Description

載貨自行車Cargo bike

本發明係關於一種載貨自行車,特別是,一種具有一可折疊框架之載貨自行車。The present invention relates to a cargo bicycle, in particular, a cargo bicycle with a foldable frame.

載貨自行車通常係已知的,且包含沿著該載貨自行車之一縱向軸線按距離定位該載貨自行車之一前輪及一後輪的一框架。典型地,載貨自行車包括一貨物固持器,其例如用來以一方便方式固持及/或運輸貨品及/或人員,特別是,兒童。通常,貨物固持器包括橫向於載貨自行車之縱向軸線延伸的一面,諸如,貨物固持器之橫向側面或底面。與例如習知二輪車或三輪車相比,該貨物固持器使載貨自行車相對較大。載貨自行車通常包括兩輪及三輪配置。在三輪配置(諸如,三輪車)之情況中,例如,在貨物固持器之各別縱向側面上的載貨自行車之縱向軸線之任一側處提供兩個前輪,且框架沿著載貨自行車之縱向軸線按距後輪一段距離定位前輪。此外,載貨自行車通常包含用於驅動該自行車之一驅動系、連接至一曲柄軸以用於嚙合該驅動系之一踏板、用於使用者坐下之一座墊配置及用於使該載貨自行車轉向之一轉向配置。雖然如上提到,載貨自行車係方便的,例如,用於運輸貨品及/或人員/兒童,但已知載貨自行車之下側為其相對大之大小,此導致載貨自行車之停車及存放問題。Cargo bicycles are generally known and include a frame that positions a front wheel and a rear wheel of the cargo bicycle at a distance along a longitudinal axis of the cargo bicycle. Typically, a cargo bicycle includes a cargo holder, which is used, for example, to hold and/or transport cargo and/or people, especially children, in a convenient manner. Generally, the cargo holder includes a side extending transversely to the longitudinal axis of the cargo bicycle, such as the transverse side or bottom surface of the cargo holder. Compared with, for example, conventional two-wheeled vehicles or three-wheeled vehicles, the cargo holder makes the cargo bicycle relatively large. Cargo bicycles usually include two-wheel and three-wheel configurations. In the case of a three-wheel configuration (such as a tricycle), for example, two front wheels are provided on either side of the longitudinal axis of the cargo bicycle on the respective longitudinal sides of the cargo holder, and the frame is pressed along the longitudinal axis of the cargo bicycle Position the front wheels at a distance from the rear wheels. In addition, cargo bicycles usually include a drive train for driving the bicycle, a pedal connected to a crankshaft for engaging the drive train, a seat cushion configuration for the user to sit on, and a seat for making the cargo bicycle Turn to one of the steering configurations. Although, as mentioned above, the cargo bicycle is convenient, for example, for transporting goods and/or people/children, it is known that the underside of the cargo bicycle is relatively large, which causes parking and storage problems for the cargo bicycle.

為了減輕劣勢,過去已提議具有一可疊起框架之載貨自行車,其經設計成在一伸長狀態與一經疊起狀態之間疊起。與伸長狀態相比,在經疊起狀態中,框架通常沿著載貨自行車之縱向軸線按一較小距離定位前輪及後輪。此對於有助於載貨自行車之停車及/或存放可為合乎需要的。In order to alleviate the disadvantages, a cargo bicycle with a stackable frame has been proposed in the past, which is designed to stack between an extended state and a folded state. Compared with the extended state, in the folded state, the frame usually positions the front and rear wheels at a smaller distance along the longitudinal axis of the cargo bicycle. This may be desirable for facilitating the parking and/or storage of cargo bicycles.

雖然具有可疊起框架之已知載貨自行車對於固持/運輸貨品及/或人員/兒童可相當令人滿意,但已發現,在經疊起狀態中的載貨自行車之緊湊性使一些事成為需要。特別是,實務上已證明提供一種具有在經疊起狀態中適當緊湊的一容易操作之可疊起框架之載貨自行車有困難。Although known cargo bicycles with a stackable frame can be quite satisfactory for holding/transporting goods and/or persons/children, it has been found that the compactness of the cargo bicycle in the folded state necessitates something. In particular, it has proved difficult in practice to provide a cargo bicycle with an easy-to-handle stackable frame that is appropriately compact in the folded state.

本發明旨在減輕前述劣勢中之一或多者。特別是,本發明旨在提供一種具有一可折疊框架之載貨自行車,其具有改良之停車及/或存儲能力,同時維持一使用者友好可折疊構造。The present invention aims to alleviate one or more of the aforementioned disadvantages. In particular, the present invention aims to provide a cargo bicycle with a foldable frame that has improved parking and/or storage capabilities while maintaining a user-friendly foldable structure.

為此目的,本發明提供一種載貨自行車,其包含:一可折疊框架,該可折疊框架可在一伸長狀態與一經折疊狀態之間調整,在該伸長狀態中,該可折疊框架沿著該載貨自行車之一縱向軸線按一第一距離定位該載貨自行車之一前輪及一後輪,在該經折疊狀態中,該可折疊框架沿著該載貨自行車之該縱向軸線按一第二較小距離定位該前輪及該後輪;用於固持貨物之一貨物固持器,其包含實質上橫向於該縱向軸線延伸之一面,且其中在該可折疊框架之該經折疊狀態中,該等輪中之至少一者橫向於該載貨自行車之該縱向軸線延伸,且至少部分與該橫向延伸之面重疊。To this end, the present invention provides a cargo bicycle comprising: a foldable frame that can be adjusted between an extended state and a folded state, in the extended state, the foldable frame runs along the cargo A longitudinal axis of the bicycle positions a front wheel and a rear wheel of the cargo bicycle at a first distance, and in the folded state, the foldable frame is positioned at a second smaller distance along the longitudinal axis of the cargo bicycle The front wheel and the rear wheel; a cargo holder for holding cargo, which includes a surface extending substantially transverse to the longitudinal axis, and wherein in the folded state of the foldable frame, at least one of the wheels One extends transversely to the longitudinal axis of the cargo bicycle, and at least partially overlaps the transversely extending surface.

藉由允許該等輪中之至少一者橫向於該載貨自行車之該縱向軸線延伸且至少部分重疊該貨物固持器之該橫向延伸之面,該相關輪可方便地向旁邊置放。特別是,該橫向延伸之面(諸如,該貨物固持器之一橫向側面或底面)可提供用於至少部分容納該相關輪之空間,較佳地,容納該輪之一區段,諸如,該輪之一圓扇形。By allowing at least one of the wheels to extend transversely to the longitudinal axis of the cargo bicycle and at least partially overlap the transversely extending surface of the cargo holder, the related wheels can be conveniently placed sideways. In particular, the laterally extending surface (such as a lateral side or bottom surface of the cargo holder) may provide a space for at least partially accommodating the relevant wheel, preferably a section of the wheel, such as the One of the rounds is fan-shaped.

在本申請案之上下文內,應將一輪橫向於該載貨自行車之該縱向軸線延伸理解為該輪之一側面實質上橫向於該載貨自行車之該縱向軸線延伸。此側面可特別暗示該輪之一圓側面。在本申請案之上下文中,術語「橫向延伸」可考慮為意謂橫跨延伸,亦即,關於與該載貨自行車之該縱向軸線成直角的偏離應在範疇內。舉例而言,當該輪或面橫向於該載貨自行車之該縱向軸線延伸時,其可自與該載貨自行車之該縱向軸線的該直角發散-30度至30度,較佳地,小於-20度至20度,諸如,-10度至10度。又,在本申請案之上下文內,術語「與……部分重疊」應解釋為該輪之部分或該輪之一輪支撐結構之部分(特別是,一輪支柱)置放至該橫向延伸之面上。特別是,該輪或輪面之部分可沿著例如該貨物固持器之該橫向側面延伸,且遵循該貨物固持器之該橫向側面之傾斜度。亦即,該輪或面之部分可例如實質上平行於該貨物固持器之該(傾斜之)橫向側面延伸。如此,在該經折疊狀態中,該輪或輪面之一下部部分可在該貨物固持器之該底面下延伸。由此,可甚至更方便地收起該輪。In the context of this application, a wheel extending transversely to the longitudinal axis of the cargo bicycle should be understood to mean that one side of the wheel extends substantially transversely to the longitudinal axis of the cargo bicycle. This side can specifically imply a round side of the wheel. In the context of this application, the term "lateral extension" can be considered to mean spanning extension, that is, deviations at right angles to the longitudinal axis of the cargo bicycle should be within the scope. For example, when the wheel or surface extends transversely to the longitudinal axis of the cargo bicycle, it can diverge from the right angle to the longitudinal axis of the cargo bicycle by -30 degrees to 30 degrees, preferably, less than -20 Degrees to 20 degrees, such as -10 degrees to 10 degrees. Also, in the context of this application, the term "partially overlaps with" should be interpreted as a part of the wheel or a part of the wheel support structure (especially, a pillar) placed on the laterally extending surface . In particular, the wheel or part of the wheel surface may extend along the lateral side of the cargo holder, for example, and follow the inclination of the lateral side of the cargo holder. That is, the part of the wheel or surface may, for example, extend substantially parallel to the (inclined) lateral side of the cargo holder. In this way, in the folded state, the wheel or a lower part of the wheel surface can extend under the bottom surface of the cargo holder. As a result, the wheel can be stowed even more conveniently.

較佳地,提供一鎖定機構用於在該經折疊狀態之一端位置中可釋放地緊固該相關輪,例如,重疊該橫向延伸之面的該輪及/或輪支撐結構之部分可緊固至該鎖定機構。由此,該相關輪可方便地向旁邊緊固,及釋放以返回至該伸長狀態。Preferably, a locking mechanism is provided for releasably securing the relevant wheel in an end position of the folded state, for example, the part of the wheel and/or the wheel support structure overlapping the laterally extending surface can be secured To the locking mechanism. Thereby, the related wheel can be conveniently fastened to the side and released to return to the extended state.

若在該框架之該經折疊狀態中,至少部分與該橫向延伸之面重疊的該至少一個輪之一輪轂實質上處於由該載貨自行車之橫向邊界界定之一封套內,則可抵消該輪轂橫向於該載貨自行車突起。較佳地,該輪轂處於由在該縱向軸線之任一側上延伸的該等橫向邊界之間的距離之四分之一界定之一封套內。如此,可達成,該輪之一實質部分處於由該載貨自行車之該等橫向邊界界定的該封套內,此又可導致在該經折疊狀態中之一更緊湊載貨自行車。橫向邊界例如由該貨物固持器之縱向側面界定,或在三輪車之情況中,例如,由沿著該貨物固持器之該等縱向側面延伸的該等前輪之側面或對稱平面界定。If in the folded state of the frame, the hub of the at least one wheel that at least partially overlaps the laterally extending surface is substantially within an envelope defined by the lateral boundary of the cargo bicycle, the lateral direction of the hub can be offset. The cargo bicycle protrudes. Preferably, the hub is within an envelope bounded by a quarter of the distance between the lateral borders extending on either side of the longitudinal axis. In this way, it can be achieved that a substantial part of the wheel is within the envelope defined by the lateral boundaries of the cargo bicycle, which in turn can result in a more compact cargo bicycle in the folded state. The lateral boundary is defined by, for example, the longitudinal sides of the cargo holder, or in the case of a tricycle, for example, by the sides or planes of symmetry of the front wheels extending along the longitudinal sides of the cargo holder.

當在該框架之該經折疊狀態中,至少部分與該橫向延伸之面重疊的該至少一個輪之一輪轂位於該縱向軸線處或附近,特別是,在該貨物固持器之該對稱平面附近或沿著該對稱平面,可有助於該輪甚至更少地橫向於該載貨自行車突起。因此,可使該構造在該經折疊狀態中甚至更緊湊。When in the folded state of the frame, the hub of the at least one wheel at least partially overlapping the laterally extending surface is located at or near the longitudinal axis, in particular, near or near the plane of symmetry of the cargo holder Along the plane of symmetry, it may be helpful for the wheel to protrude even less transversely to the cargo bike. Therefore, the configuration can be made even more compact in this folded state.

藉由將該可折疊框架之至少一部分(特別是,該載貨自行車之一輪支撐結構)鉸鏈連接至該可折疊框架以便可圍繞實質上橫向於該縱向軸線延伸之一豎直軸線樞轉,可有助於使相關輪樞轉以實質上橫向於該載貨自行車之該縱向軸線延伸。特別是,藉由鉸鏈連接該輪支撐結構(諸如,一輪支柱),可有助於可將該輪支撐結構置放至該橫向延伸之面上。該輪支撐結構或所謂的輪支柱可包含一後上叉及/或後下叉。較佳地,提供一支柱鉸鏈以允許該可折疊框架之至少一部分相對於該可折疊框架樞轉。如此,可達成一相對簡單之可折疊構造。By hinge-connecting at least a part of the foldable frame (especially, the wheel support structure of the cargo bicycle) to the foldable frame so as to be pivotable about a vertical axis extending substantially transverse to the longitudinal axis, there may be Helps pivot the related wheels to extend substantially transverse to the longitudinal axis of the cargo bicycle. In particular, connecting the wheel support structure (such as a wheel support) by a hinge can help to place the wheel support structure on the laterally extending surface. The wheel support structure or so-called wheel strut may include a seat stay and/or chain stay. Preferably, a pillar hinge is provided to allow at least a part of the foldable frame to pivot relative to the foldable frame. In this way, a relatively simple foldable structure can be achieved.

因此描述一種載貨自行車,其包含一可折疊框架,該可折疊框架可在如上所述之一伸長狀態與一經折疊狀態之間調整,進一步包含一貨物固持器,該貨物固持器具有實質上橫向於該載貨自行車之該縱向軸線延伸的一面,其中在該可折疊框架之該經折疊狀態中,該等輪中之至少一者橫向於該載貨自行車之該縱向軸線延伸且至少部分與該橫向延伸之面重疊。特別是,當作為該可折疊框架之部分的該載貨自行車之一輪支撐結構之至少一部分鏈接連接至該可折疊框架之一其餘部分時,該輪支撐結構及/或輪支柱之該部分可方便地圍繞一樞軸線樞轉,該樞軸線實質上橫向於該載貨自行車之該縱向軸線延伸。如此,該輪支撐結構及/或輪支柱之該部分可朝向該貨物固持器之該橫向延伸之面折疊,使得在該經折疊狀態中的各別該前輪及/或該後輪至少部分與該橫向延伸之面重疊,因此允許各別該前輪及/或該後輪方便地向旁邊置放,特別是與諸如坐墊支柱及/或後下叉的輪支撐結構之至少一部分一起。因此,可達成在該經折疊狀態中之一特別緊湊構造,其可接取且相對易於在該伸長狀態與該經折疊狀態之間調整。以此方式,該載貨自行車可方便地具備典型自行車輪(亦即,相對普通、市售輪),及具有一標稱輪緣及輪胎大小(諸如,根據歐洲輪胎及輪緣技術組織(ETRTO)標準之大約559 mm、590 mm、622 mm或635 mm)之輪胎。由此,具備鉸鏈連接至該可折疊框架之其餘部分的該輪支撐結構之一部分的該載貨自行車可裝備有有益於在該伸長狀態中的該載貨自行車之騎車舒適度之典型輪,同時維持在該經折疊狀態中之一特別緊湊構造,該構造相對易於操作及在各別該伸長狀態與該經折疊狀態之間調整。特別是,該輪支撐結構之該部分可經由至少一個鉸鏈(例如,提供於該輪支撐結構之一後下叉部件、一後上叉部件及/或叉頭部件上)鉸鏈連接。亦即,該至少一個鉸鏈提供於該輪支撐結構上,在一輪懸架與例如一曲柄軸及/或該輪支撐結構至該可折疊框架之一其餘部分(諸如,座管或主管)的一連接之間。Therefore, a cargo bicycle is described, which includes a foldable frame that can be adjusted between an extended state and a folded state as described above, and further includes a cargo holder that is substantially transverse to The side of the cargo bicycle on which the longitudinal axis extends, wherein in the folded state of the foldable frame, at least one of the wheels extends transversely to the longitudinal axis of the cargo bicycle and is at least partially aligned with the transverse extension The faces overlap. In particular, when at least a part of the wheel support structure of the cargo bicycle as part of the foldable frame is linked to the rest of the foldable frame, the part of the wheel support structure and/or the wheel strut can be conveniently Pivoting about a pivot axis, the pivot axis extending substantially transverse to the longitudinal axis of the cargo bicycle. In this way, the part of the wheel support structure and/or the wheel strut can be folded toward the transversely extending surface of the cargo holder, so that the respective front wheel and/or the rear wheel in the folded state are at least partly connected to the The laterally extending surfaces overlap, thus allowing the respective front wheel and/or the rear wheel to be conveniently placed sideways, especially with at least a part of the wheel support structure such as the cushion pillar and/or chainstay. Therefore, a particularly compact configuration can be achieved in the folded state, which is accessible and relatively easy to adjust between the extended state and the folded state. In this way, the cargo bicycle can conveniently be equipped with typical bicycle wheels (ie, relatively ordinary, commercially available wheels), and have a nominal rim and tire size (such as according to the European Tire and Rim Technology Organization (ETRTO) The standard tires are approximately 559 mm, 590 mm, 622 mm or 635 mm). Thus, the cargo bicycle provided with a part of the wheel support structure hingedly connected to the rest of the foldable frame can be equipped with typical wheels that are beneficial to the riding comfort of the cargo bicycle in the extended state, while maintaining One of the folded states is particularly compact, which is relatively easy to handle and adjust between the respective extended state and the folded state. In particular, the part of the wheel support structure may be hingedly connected via at least one hinge (for example, provided on a chainstay member, an upper fork member and/or a fork member of the wheel support structure). That is, the at least one hinge is provided on the wheel support structure, a connection of a wheel suspension and, for example, a crank axle and/or the wheel support structure to the rest of the foldable frame (such as a seat tube or main pipe) between.

當該可折疊框架之至少一部分(較佳地,全部框架)可圍繞一水平軸線樞轉時,在該伸長狀態中,該水平軸線實質上沿著該載貨自行車之該縱向軸線延伸,可有助於使該相關輪樞轉以實質上橫向於該載貨自行車之該縱向軸線延伸。在本申請案之上下文中,術語「沿著……延伸」應解釋為意謂平行於例如該載貨自行車之該縱向軸線或與該縱向軸線重合。When at least a part of the foldable frame (preferably, the entire frame) can pivot about a horizontal axis, in the extended state, the horizontal axis extends substantially along the longitudinal axis of the cargo bicycle, which can help The related wheel is pivoted to extend substantially transversely to the longitudinal axis of the cargo bicycle. In the context of this application, the term "extends along" shall be interpreted as meaning parallel to or coincide with the longitudinal axis of the cargo bicycle, for example.

若該可折疊框架包含一基底部分及在該伸長狀態與該經折疊狀態之間沿著該縱向軸線相對於該基底部分可滑動且反之亦然之一伸縮部分,則可允許該伸縮部分滑入及滑出該基底部分。如此,在該經折疊狀態中,可獲得一相對緊湊構造。藉由圍繞該伸縮部分配置該基底部分作為一套管,使得該伸縮部分可滑動穿過該基底部分,可實現用於折疊該框架之一相對簡單構造。較佳地,該基底部分相對於提供於該貨物固持器上之另一套管可滑動,使得該基底部分可沿著該縱向軸線關於該貨物固持器伸縮滑動。此允許在該載貨自行車之該經折疊狀態中的一特別緊湊構造。If the foldable frame includes a base portion and a telescopic portion that is slidable relative to the base portion along the longitudinal axis and vice versa between the extended state and the folded state, the telescopic portion can be allowed to slide in And slide out the base part. In this way, in this folded state, a relatively compact structure can be obtained. By arranging the base part as a sleeve tube around the telescopic part, so that the telescopic part can slide through the base part, a relatively simple structure for folding the frame can be realized. Preferably, the base part is slidable relative to another sleeve provided on the cargo holder, so that the base part can telescopically slide with respect to the cargo holder along the longitudinal axis. This allows a particularly compact construction in the folded state of the cargo bicycle.

藉由提供將該可折疊框架之一第一部分鉸鏈連接至一第二部分的一第一鉸鏈,該等兩個部分可朝向彼此疊起。若該第一鉸鏈可在該等各別伸長及經折疊狀態中鎖定,則在兩個各別狀態中可實現該載貨自行車之一相對穩定構造。較佳地,該第一鉸鏈位於該貨物固持器之一底面下。亦即,該第一鉸鏈較佳地位於由該貨物固持器之該底面之邊界界定的一封套內。藉由使該第一鉸鏈位於該底面下,可有助於在該經折疊狀態中在該載貨自行車之該底面下方便地收起該等兩個部分。By providing a first hinge connecting a first part of the foldable frame to a second part, the two parts can be stacked toward each other. If the first hinge can be locked in the respective extended and folded states, a relatively stable structure of the cargo bicycle can be realized in the two respective states. Preferably, the first hinge is located under a bottom surface of the cargo holder. That is, the first hinge is preferably located in an envelope defined by the boundary of the bottom surface of the cargo holder. By positioning the first hinge under the bottom surface, it can help to conveniently store the two parts under the bottom surface of the cargo bicycle in the folded state.

藉由進一步提供將該可折疊框架之該第二部分鉸鏈連接至一第三部分的一第二鉸鏈,且其中該第二鉸鏈可在各別該伸長狀態及該經折疊狀態中鎖定,可有助於該等各別部分可朝向彼此折疊,正似一手風琴。如此,可在該經折疊狀態中實現一特別緊湊構造。特別是,當該第一鉸鏈及該第二鉸鏈經置放使得允許該可折疊框架之至少兩個部分在該經折疊狀態中部分地沿著彼此延伸時。By further providing a second hinge connecting the second part of the foldable frame to a third part, and wherein the second hinge can be locked in the extended state and the folded state, respectively, there may be This helps the individual parts to be folded towards each other, just like an accordion. In this way, a particularly compact structure can be achieved in this folded state. In particular, when the first hinge and the second hinge are placed so as to allow at least two parts of the foldable frame to partially extend along each other in the folded state.

若該載貨自行車之一驅動系包括一齒狀帶用於在該驅動系中之動力傳輸,則可達成可疊起的該驅動系之一靈活構造。結合該可折疊框架之該可樞轉部分(特別是,一輪支撐結構),此特別有用,因為此可允許該驅動系之一部分與此可樞轉部分一起樞轉。可置放一齒狀帶導塊,例如,在該支柱鉸鏈附近或作為該支柱鉸鏈之部分,以導引該齒狀帶且有助於該齒狀帶之打褶,例如,圍繞該支柱鉸鏈。If a drive train of the cargo bicycle includes a toothed belt for power transmission in the drive train, a flexible structure of the drive train that can be stacked can be achieved. This is particularly useful in combination with the pivotable part of the foldable frame (especially a wheel support structure) because it allows a part of the drive train to pivot together with the pivotable part. A toothed belt guide block can be placed, for example, near the pillar hinge or as part of the pillar hinge to guide the toothed belt and facilitate the pleating of the toothed belt, for example, around the pillar hinge .

當用於收納一座位及/或座桿的該載貨自行車之一座管固定至該載貨自行車之該可樞轉部分(特別是,該輪支撐結構)使得其可與該可折疊框架一起或關於該可折疊框架樞轉時,可達成一特別簡單且精緻構造,其允許沿著該貨物固持器之橫向側或底面將座位與相關輪一起方便地收起。此有助於易於使用該可折疊框架,同時維持或改良該載貨自行車在該經折疊狀態中之緊湊性。When a seat tube of the cargo bicycle for accommodating a seat and/or seatpost is fixed to the pivotable part (in particular, the wheel support structure) of the cargo bicycle so that it can be together with the foldable frame or in relation to the foldable frame When the foldable frame is pivoted, a particularly simple and delicate structure can be achieved, which allows the seat and related wheels to be conveniently stowed along the lateral side or bottom surface of the cargo holder. This helps to facilitate the use of the foldable frame while maintaining or improving the compactness of the cargo bicycle in the folded state.

若用於收納一座位及/或座桿的該載貨自行車之一座管鉸鏈連接至該可折疊框架,使得該座管可在一疊入位置(其中該座管位置較接近在該貨物固持器之該橫向底面下且實質上平行於該橫向底面延伸之一平面)與一疊出位置(其中該座管位置較遠離該平面,特別是,使得該座管實質上豎直地延伸至該平面以提供在該可折疊框架之該伸長狀態中的一座墊配置)之間折疊,則可進一步有助於在該經折疊狀態中在該貨物固持器之該底面下的該可折疊框架之收起。由此,在該經折疊狀態中,包括該座位及/或該座桿之該座管可實質上在該貨物固持器之該底面下延伸。如此,可在該經折疊狀態中達成一特別精緻且緊湊構造。較佳地,提供一快速鎖定機構,例如,在該載貨自行車上或在該座桿上,其允許座位高度之簡單降低及升高。如此,可相對容易地在一降低之狀態與一升高之狀態之間調整座管與座位總成,例如,同時考量使用者對座位之首選使用高度。If a seat tube of the cargo bicycle for storing a seat and/or seatpost is hinged to the foldable frame, the seat tube can be in a stacking position (where the seat tube is closer to the cargo holder) A plane extending under the lateral bottom surface and substantially parallel to the lateral bottom surface) and a stacking position (where the seat tube is located farther away from the plane, in particular, so that the seat tube extends substantially vertically to the plane. The provision of folding between the seat cushion configuration in the extended state of the foldable frame can further facilitate the folding of the foldable frame under the bottom surface of the cargo holder in the folded state . Thus, in the folded state, the seat tube including the seat and/or the seat post can substantially extend under the bottom surface of the cargo holder. In this way, a particularly delicate and compact structure can be achieved in the folded state. Preferably, a quick locking mechanism is provided, for example, on the cargo bicycle or on the seatpost, which allows simple lowering and raising of the seat height. In this way, it is relatively easy to adjust the seat tube and the seat assembly between a lowered state and an elevated state, for example, while considering the user's preferred use height for the seat.

若在該經折疊狀態中實質上全部可折疊框架經沿著該貨物固持器之橫向於該縱向軸線延伸的面(諸如,該貨物固持器之橫向側面及底面)收起,且該可折疊框架實質上處於由該載貨自行車之橫向邊界界定的一封套內,則可抵消該可折疊框架之部分突起於該封套之外。由此,在該經折疊狀態中,可獲得一特別精緻且緊湊構造。If in the folded state, substantially all of the foldable frame is retracted by a surface extending along the cargo holder transverse to the longitudinal axis (such as the lateral side and bottom surface of the cargo holder), and the foldable frame Substantially within the envelope defined by the lateral boundary of the cargo bicycle, the part of the foldable frame protruding outside the envelope can be offset. Thus, in this folded state, a particularly delicate and compact structure can be obtained.

具有或無可疊起框架的習知載貨自行車之另一缺點為,不應留下在貨物固持器中未被注意到的貨品及/或人員/兒童,例如,當辦事時或在購物期間。本發明進一步旨在減輕習知載貨自行車之此缺點。特別是,本發明旨在提供一種具有一可折疊框架之載貨自行車,在經折疊狀態中,該可折疊框架可相對易於走路帶著。Another disadvantage of conventional cargo bicycles with or without a stackable frame is that they should not leave unnoticeable goods and/or persons/children in the cargo holder, for example, when doing business or during shopping. The present invention further aims to alleviate this shortcoming of conventional cargo bicycles. In particular, the present invention aims to provide a cargo bicycle with a foldable frame, which can be carried relatively easily when in a folded state.

如前所提到,藉由配置在該可折疊框架之經折疊狀態中的載貨自行車之至少一個輪以沿著橫向延伸之面及至該橫向延伸之面上置放,使得該至少一個輪至少部分與該橫向延伸之面重疊,允許相關輪向旁邊置放。此外,藉由沿著該橫向延伸之面(諸如,該貨物固持器之橫向側面或底面)及至該橫向延伸之面上置放相關輪,允許一使用者相對容易地在該載貨自行車之該橫向側面後實質上成方形地定位其自身。由此,在經折疊狀態中之載貨自行車可易於用作一推車。以此方式,貨品及/或人員/兒童不必自貨物固持器移除,例如,當辦事時或在購物期間。此節省了大量時間及催促,尤其當帶著兒童時。購買之貨品(例如,雜貨)可方便地在貨物固持器中運輸,甚至與人員/兒童一起。在購物後,載貨自行車可相對容易地轉換回至一騎行狀態,且可相對快速地騎行。此可節省大量時間及體能。As mentioned above, the at least one wheel of the cargo bicycle arranged in the folded state of the foldable frame is placed along the laterally extending surface and to the laterally extending surface, so that the at least one wheel is at least partially Overlap with the laterally extending surface, allowing the relevant wheels to be placed sideways. In addition, by placing relevant wheels along the laterally extending surface (such as the lateral side or bottom surface of the cargo holder) and onto the laterally extending surface, it allows a user to relatively easily move on the lateral surface of the cargo bicycle. It positions itself substantially squarely behind the side. Thus, the cargo bicycle in the folded state can be easily used as a cart. In this way, the goods and/or persons/children do not have to be removed from the goods holder, for example, when doing business or during shopping. This saves a lot of time and haste, especially when taking children. Purchased goods (for example, groceries) can be easily transported in the cargo holder, even with people/children. After shopping, the cargo bicycle can be converted back to a riding state relatively easily, and can be ridden relatively quickly. This can save a lot of time and energy.

若該載貨自行車進一步包含支撐於該框架及/或該貨物固持器上之至少一個支撐件以用於在一表面(特別是,地面)上支撐該載貨自行車,則可相對容易地達成一相對簡單且穩定構造,特別是,在該經折疊狀態中。If the cargo bicycle further includes at least one support member supported on the frame and/or the cargo holder for supporting the cargo bicycle on a surface (especially, the ground), a relatively simple structure can be achieved relatively easily And the structure is stable, especially, in this folded state.

當該載貨自行車包含用於該至少一個支撐件之一可收縮總成時,可提供一相對簡單構造用於相對容易地收起該至少一個支撐件,例如,當騎行時,或為了穩定性而將其降低,例如,在該經折疊狀態中,該可收縮總成可在該至少一個支撐件在該框架及/或該貨物固持器之一方向上收縮之一收縮狀態與降低該至少一個支撐件以用於在一表面上支撐該載貨自行車之一支撐狀態之間調整。When the cargo bicycle includes a retractable assembly for the at least one support member, a relatively simple structure can be provided for relatively easy storage of the at least one support member, for example, when riding, or for stability Lower it, for example, in the folded state, the collapsible assembly can shrink in a contracted state and lower the at least one support in a direction of the frame and/or the cargo holder. It is used to support the cargo bicycle on a surface and adjust between a supporting state.

當該至少一個支撐件包含一輪或由一輪形成時,特別是,一自位輪(swivel wheel),該載貨自行車可在該經折疊狀態中相對容易且穩定地移位。當在經折疊狀態中將該載貨自行車用作一推車時,此特別有用。When the at least one support includes a wheel or is formed of a wheel, in particular, a swivel wheel, the cargo bicycle can be displaced relatively easily and stably in the folded state. This is particularly useful when the cargo bicycle is used as a cart in the folded state.

The foldable cargo bicycle 1 includes a foldable frame 2. The foldable frame can be adjusted between an extended state I and a folded state II. In the extended state I, the foldable frame 2 presses a first distance L1 along a longitudinal axis 5 of the cargo bicycle 1 (see Figure 3) The front wheel 3 and the rear wheel 4 of the cargo bicycle 1 are positioned. In the folded state II, the foldable frame 2 positions the front wheel 3 and the rear wheel 4 along the longitudinal axis 5 of the cargo bicycle 1 at a second smaller distance L2. The cargo bicycle 1 includes a cargo holder 6 for holding cargo. The cargo holder 6 includes a side 7 extending substantially transversely to the longitudinal axis 5 of the cargo bicycle 1, such as the transverse side 7a or the bottom surface 7b of the cargo holder 6. This exemplary embodiment is a tricycle, so that the cargo bicycle 1 includes two front wheels 3 placed along the longitudinal sides 8 of the cargo holder 6. The two-wheel configuration is shown in FIG. 6 and discussed in more detail later, in which a single front wheel 3 is placed at or near an opposite end of the cargo holder 6 with respect to the rear wheel 4. The front wheel 3 can be arranged on the cargo holder 6, the foldable frame 2 or the wheel support structure 9 of the cargo bicycle, for example. In this exemplary embodiment, the front wheel 3 is configured on a wheel support structure 9 connected to the cargo holder 6.

此處,在圖1之可折疊框架2之經折疊狀態II中,後輪4橫向於載貨自行車1之縱向軸線5延伸,且至少部分與橫向延伸之面7重疊,亦即,用於後輪4之輪支撐結構9置放至橫向側面7a上。載貨自行車1進一步包含一鎖定機構10,用於在橫向延伸之面7上的經折疊狀態II之一端位置中可釋放地緊固後輪4。Here, in the folded state II of the foldable frame 2 of FIG. 1, the rear wheel 4 extends transversely to the longitudinal axis 5 of the cargo bicycle 1, and at least partially overlaps the transversely extending surface 7, that is, for the rear wheel The wheel support structure 9 of 4 is placed on the lateral side 7a. The cargo bicycle 1 further includes a locking mechanism 10 for releasably securing the rear wheel 4 in an end position of the folded state II on the laterally extending surface 7.

用於後輪4的載貨自行車1之輪支撐結構9鉸鏈連接至可折疊框架2。在此例示性實施例中,用於後輪4之輪支撐結構9由一支柱鉸鏈11連接至可折疊框架2。此處,支柱鉸鏈11提供於一後下叉部件(下部)上,且經由支柱鉸鏈11將輪支撐結構9連接至可折疊框架2之其餘部分。替代地,支柱鉸鏈可提供於後上叉部件(上部)或後上叉部件及後下充滿部件兩者上。亦即,支柱鉸鏈11將後下叉部件鉸鏈耦接至該框架之一主管,作為可折疊框架2之其餘部分。支柱鉸鏈定位於後輪4之一輪懸架與載貨自行車1之一曲柄軸之間。另外或替代地,用於後輪4之輪支撐結構9可由可折疊框架2包含或形成可折疊框架2之部分,使得可折疊框架2之一部分可相對於可折疊框架2樞轉。此處,在經折疊狀態II中,使輪支撐結構9關於可折疊框架2圍繞支柱鉸鏈11樞轉,使得後輪4至少部分與橫向側面7a重疊。支柱鉸鏈11界定一實質上豎直軸線12,其實質上橫向於載貨自行車1之縱向軸線5延伸。較佳地,支柱鉸鏈11之豎直軸線12實質上平行於貨物固持器6之橫向側面7a延伸,使得輪之至少一部分重疊在經折疊狀態中的橫向側面7a。The wheel support structure 9 of the cargo bicycle 1 for the rear wheel 4 is hingedly connected to the foldable frame 2. In this exemplary embodiment, the wheel support structure 9 for the rear wheel 4 is connected to the foldable frame 2 by a pillar hinge 11. Here, the pillar hinge 11 is provided on a chainstay member (lower part), and the wheel support structure 9 is connected to the rest of the foldable frame 2 via the pillar hinge 11. Alternatively, the strut hinge may be provided on the seat stay (upper part) or both the seat stay and the lower rear filling part. That is, the pillar hinge 11 couples the chainstay hinge to a main pipe of the frame as the remaining part of the foldable frame 2. The pillar hinge is positioned between the one-wheel suspension of the rear wheel 4 and the crankshaft of the cargo bicycle 1. Additionally or alternatively, the wheel support structure 9 for the rear wheels 4 may be included by the foldable frame 2 or form part of the foldable frame 2 so that a part of the foldable frame 2 can pivot relative to the foldable frame 2. Here, in the folded state II, the wheel support structure 9 is pivoted about the pillar hinge 11 with respect to the foldable frame 2 so that the rear wheel 4 at least partially overlaps the lateral side 7a. The pillar hinge 11 defines a substantially vertical axis 12 that extends substantially transversely to the longitudinal axis 5 of the cargo bicycle 1. Preferably, the vertical axis 12 of the pillar hinge 11 extends substantially parallel to the lateral side 7a of the cargo holder 6, so that at least a part of the wheel overlaps the lateral side 7a in the folded state.

在此例示性實施例中,將載貨自行車1之前輪3及後輪4提供為典型輪,亦即,相對普通、市售輪及具有一標稱輪緣及根據歐洲輪胎及輪緣技術組織(ETRTO)標準之635 mm之輪胎大小的輪胎。然而,可提供任一普通、市售輪,例如,具有一標稱輪緣及在大約406 mm至642 mm之間的輪胎大小,諸如,大約559 mm、590 mm、622 mm。In this exemplary embodiment, the front wheel 3 and the rear wheel 4 of the cargo bicycle 1 are provided as typical wheels, that is, relatively common, commercially available wheels and have a nominal rim and according to the European Tire and Rim Technical Organization ( ETRTO) standard tires with a tire size of 635 mm. However, any common, commercially available wheel can be provided, for example, with a nominal rim and a tire size between approximately 406 mm and 642 mm, such as approximately 559 mm, 590 mm, and 622 mm.

載貨自行車1包含一第一鉸鏈13,其將可折疊框架2之一第一部分14鉸鏈連接至一第二部分15,此可在圖4中更清晰地看出且稍後描述。該第一鉸鏈13位於該貨物固持器6之一底面7b下。用於收納一座位20及/或座桿的載貨自行車1之座管19固定至載貨自行車1之輪支撐結構9。座管19及輪支撐結構9可關於可折疊框架2一起樞轉。The cargo bicycle 1 includes a first hinge 13 that hinges a first part 14 of the foldable frame 2 to a second part 15, which can be seen more clearly in FIG. 4 and described later. The first hinge 13 is located under a bottom surface 7b of the cargo holder 6. The seat tube 19 of the cargo bicycle 1 for storing a seat 20 and/or a seatpost is fixed to the wheel support structure 9 of the cargo bicycle 1. The seat tube 19 and the wheel support structure 9 can pivot together with respect to the foldable frame 2.

圖2展示在可折疊框架2之經折疊狀態II中的載貨自行車1之第二實施例。用於後輪4之輪支撐結構9形成可折疊框架2之部分。至少部分與貨物固持器6之底面7b重疊的後輪4之一輪轂16實質上處於由載貨自行車1之橫向邊界界定的一封套17內。如可在圖2中看出,橫向邊界可由貨物固持器6之縱向側面8 (亦即,封套17')界定,或由沿著該側面8 (封套17)延伸的前輪3之平面界定。此處,後輪4之輪轂16處於一封套17''內。封套17''由在載貨自行車1之縱向軸線5之任一側上延伸的橫向邊界之間的距離之四分之一界定。此外,後輪4之輪轂16位於載貨自行車1之縱向軸線5附近。在此例示性實施例中,載貨自行車之縱向軸線5與貨物固持器6之對稱平面重合。FIG. 2 shows a second embodiment of the cargo bicycle 1 in the folded state II of the foldable frame 2. The wheel support structure 9 for the rear wheel 4 forms part of the foldable frame 2. A hub 16 of the rear wheel 4 that at least partially overlaps the bottom surface 7b of the cargo holder 6 is substantially within an envelope 17 defined by the lateral boundary of the cargo bicycle 1. As can be seen in Figure 2, the lateral boundary may be defined by the longitudinal side 8 of the cargo holder 6 (ie, the envelope 17'), or by the plane of the front wheel 3 extending along the side 8 (envelope 17). Here, the hub 16 of the rear wheel 4 is in an envelope 17". The envelope 17" is defined by a quarter of the distance between the lateral borders extending on either side of the longitudinal axis 5 of the cargo bicycle 1. In addition, the hub 16 of the rear wheel 4 is located near the longitudinal axis 5 of the cargo bicycle 1. In this exemplary embodiment, the longitudinal axis 5 of the cargo bicycle coincides with the plane of symmetry of the cargo holder 6.

參看圖2,可折疊框架2之至少一部分可圍繞一水平軸線18樞轉,在可折疊框架2之伸長狀態中,該水平軸線18實質上沿著載貨自行車1之縱向軸線5延伸。此處,可折疊框架2可圍繞水平軸線18樞轉四分之一圈,例如,藉由按提供於可折疊框架2上的一或多個擋板之形式提供,其限制圍繞水平軸線18之移動(未展示)。用於收納一座位20及/或座桿的可折疊框架2之座管19固定至可折疊框架2之輪支撐結構9,且亦形成框架2之部分。座管19及輪支撐結構9可與可折疊框架2一起樞轉。Referring to FIG. 2, at least a part of the foldable frame 2 can pivot about a horizontal axis 18 which extends substantially along the longitudinal axis 5 of the cargo bicycle 1 in the extended state of the foldable frame 2. Here, the foldable frame 2 can pivot about a quarter turn around the horizontal axis 18, for example, by being provided in the form of one or more baffles provided on the foldable frame 2, which restricts the movement around the horizontal axis 18 Mobile (not shown). The seat tube 19 of the foldable frame 2 for accommodating a seat 20 and/or a seatpost is fixed to the wheel support structure 9 of the foldable frame 2 and also forms a part of the frame 2. The seat tube 19 and the wheel support structure 9 can pivot together with the foldable frame 2.

可折疊框架2包含一基底部分21,及可沿著縱向軸線5在伸長狀態I與經折疊狀態II之間相對於基底部分21滑動之一伸縮部分22。相反地,伸縮部分22可沿著縱向軸線5自經折疊狀態II滑動至伸長狀態I。將基底部分21圍繞伸縮部分22配置為一套管,使得伸縮部分22可滑動穿過基底部分21。又,該基底部分21相對於提供於貨物固持器上之另一套管23可滑動,使得該基底部分可沿著該縱向軸線關於該貨物固持器伸縮滑動。在此實施例中,載貨自行車1包含一驅動系24,其包括用於驅動驅動系24之一鏈條25。替代地,例如,可包括一齒狀帶以用於驅動驅動系24,或驅動系24可包含直接與一從動軸桿合作之一驅動軸桿。在後者情況中,驅動軸桿及從動軸桿例如可在其相互直接接觸之一經耦接狀態與其經去耦且間隔開之一經去耦狀態之間調整。如此,在經去耦狀態中,驅動軸桿及從動軸桿可與可折疊框架2之一可樞轉部分(特別是,輪支撐結構9)一起相對於彼此樞轉。The foldable frame 2 includes a base portion 21 and a telescopic portion 22 that can slide relative to the base portion 21 between the extended state I and the folded state II along the longitudinal axis 5. Conversely, the telescopic portion 22 can slide along the longitudinal axis 5 from the folded state II to the extended state I. The base portion 21 is configured as a sleeve tube around the telescopic portion 22 so that the telescopic portion 22 can slide through the base portion 21. Furthermore, the base part 21 is slidable relative to another sleeve 23 provided on the cargo holder, so that the base part can telescopically slide with respect to the cargo holder along the longitudinal axis. In this embodiment, the cargo bicycle 1 includes a drive train 24 including a chain 25 for driving the drive train 24. Alternatively, for example, a toothed belt may be included for driving the drive train 24, or the drive train 24 may include a drive shaft that directly cooperates with a driven shaft. In the latter case, the drive shaft and the driven shaft can be adjusted, for example, between a coupled state in which they are in direct contact with each other and a decoupled state in which they are decoupled and spaced apart. In this way, in the decoupled state, the drive shaft and the driven shaft can pivot relative to each other together with one of the pivotable parts of the foldable frame 2 (in particular, the wheel support structure 9).

圖3展示在一伸長狀態I中的載貨自行車1之第三實施例。可折疊框架2沿著載貨自行車1之縱向軸線5按第一距離L1定位載貨自行車1之前輪3及後輪4。載貨自行車1包含兩個前輪3,其經由一輪支撐結構9可旋轉地安裝至貨物固持器6。轉向控制26 (特別是,車把)提供於貨物固持器6上。載貨自行車1之可樞轉轉向機構27將可折疊框架2可樞轉地連接至貨物固持器6。載貨自行車1之座管19鉸鏈連接至可折疊框架2。一座管鉸鏈28提供至其處。座管19處於一疊出位置α中,在該疊出位置α中,座管19位置較遠離在貨物固持器6之底面7b下且實質上平行於該底面7b延伸之一平面,特別是,使得座管19實質上豎直地延伸至該平面以提供在可折疊框架2之伸長狀態I中的一座墊配置。提供一鎖定構件c,用於將座管可釋放地緊固於疊出位置α中。鎖定構件c亦充當用於在各別伸長狀態I及經折疊狀態II中可釋放地緊固第一鉸鏈13之鎖定機構。又,提供一緊固機構d,用於將後輪4之輪支撐結構9可釋放地緊固至可折疊框架2。另外或替代地,可提供緊固機構d用於將座管19可釋放地緊固至後輪4之輪支撐結構9。特別是,該緊固機構d可由提供於座管19上之一開關(未展示)控制。提供一快速鎖定機構b,用於相對快速地降低及升高座位20。如此,可相對容易地在一降低之狀態與一升高之狀態之間調整座管19與座位20總成,例如,同時考量使用者對座位20之首選使用高度。特別是,座位20之降低及/或升高可用來方便地控制提供於座管19上之開關。另外或替代地,一把手a可方便地提供於座位20處或附近以操作用於降低及升高座位20之快速鎖定機構b (見圖3)。FIG. 3 shows a third embodiment of the cargo bicycle 1 in an extended state I. The foldable frame 2 positions the front wheel 3 and the rear wheel 4 of the cargo bicycle 1 along the longitudinal axis 5 of the cargo bicycle 1 at a first distance L1. The cargo bicycle 1 includes two front wheels 3, which are rotatably mounted to a cargo holder 6 via a wheel support structure 9. The steering control 26 (especially, the handlebar) is provided on the cargo holder 6. The pivotable steering mechanism 27 of the cargo bicycle 1 pivotally connects the foldable frame 2 to the cargo holder 6. The seat tube 19 of the cargo bicycle 1 is hingedly connected to the foldable frame 2. A tube hinge 28 is provided to it. The seat tube 19 is in a stacking-out position α. In the stacking-out position α, the seat tube 19 is positioned farther away from a plane extending under the bottom surface 7b of the cargo holder 6 and substantially parallel to the bottom surface 7b, in particular, The seat tube 19 is made to extend substantially vertically to the plane to provide a seat cushion configuration in the extended state I of the foldable frame 2. A locking member c is provided for releasably securing the seat tube in the stacking-out position α. The locking member c also serves as a locking mechanism for releasably securing the first hinge 13 in the respective extended state I and the folded state II. Furthermore, a fastening mechanism d is provided for releasably fastening the wheel support structure 9 of the rear wheel 4 to the foldable frame 2. Additionally or alternatively, a fastening mechanism d may be provided for releasably fastening the seat tube 19 to the wheel support structure 9 of the rear wheel 4. In particular, the fastening mechanism d can be controlled by a switch (not shown) provided on the seat tube 19. A quick locking mechanism b is provided for lowering and raising the seat 20 relatively quickly. In this way, it is relatively easy to adjust the assembly of the seat tube 19 and the seat 20 between a lowered state and an elevated state, for example, while considering the user's preferred height of use of the seat 20. In particular, the lowering and/or raising of the seat 20 can be used to conveniently control the switch provided on the seat tube 19. Additionally or alternatively, a handle a can be conveniently provided at or near the seat 20 to operate the quick lock mechanism b for lowering and raising the seat 20 (see FIG. 3).

另外或替代地,可樞轉轉向機構27可經配置以包括一轉向連桿組,該轉向連桿組具備一或多個控制桿、一搖桿及連接至各前輪3之一轉向桿或具備與前輪3之轉向齒條合作之一小齒輪的一轉向軸桿。在此後者情況中,轉向齒條經由一各別樞軸點連接至各前輪3。安裝於貨物固持器6上(例如,經由一輪支撐結構9)之各前輪3經配置以圍繞一豎直軸線樞轉,該豎直軸線實質上橫向於載貨自行車1之縱向軸線5延伸以允許其轉向。在可轉向前輪3之情況中,可提供用於將貨物固持器6可釋放地緊固至可折疊框架2之一樞軸鎖定機構(未展示),例如,以將載貨自行車1鎖定於伸長狀態I中。Additionally or alternatively, the pivotable steering mechanism 27 may be configured to include a steering linkage group having one or more control rods, a rocker, and a steering rod connected to each of the front wheels 3 or A steering shaft with a pinion that cooperates with the steering rack of the front wheel 3. In this latter case, the steering rack is connected to each front wheel 3 via a separate pivot point. Each front wheel 3 mounted on the cargo holder 6 (for example, via a wheel support structure 9) is configured to pivot about a vertical axis that extends substantially transversely to the longitudinal axis 5 of the cargo bicycle 1 to allow it Steering. In the case of the steerable front wheel 3, a pivot locking mechanism (not shown) for releasably fastening the cargo holder 6 to the foldable frame 2 may be provided, for example, to lock the cargo bicycle 1 in the extended state I.

在此例示性實施例中,將載貨自行車1之前輪3及後輪4提供為典型輪,亦即,相對普通、市售輪及具有一標稱輪緣及根據歐洲輪胎及輪緣技術組織(ETRTO)標準之622 mm之輪胎大小的輪胎。然而,可提供任一普通、市售輪,例如,具有一標稱輪緣及在大約406 mm至642 mm之間的輪胎大小,諸如,大約559 mm、590 mm、622 mm。In this exemplary embodiment, the front wheel 3 and the rear wheel 4 of the cargo bicycle 1 are provided as typical wheels, that is, relatively common, commercially available wheels and have a nominal rim and according to the European Tire and Rim Technical Organization ( ETRTO) standard tires with a tire size of 622 mm. However, any common, commercially available wheel can be provided, for example, with a nominal rim and a tire size between approximately 406 mm and 642 mm, such as approximately 559 mm, 590 mm, and 622 mm.

圖4展示在經折疊狀態II中的圖3之載貨自行車1之簡化示意性俯視圖。此處,可看出,可樞轉轉向機構27充當一第二鉸鏈,其將可折疊框架2之第一部分14鉸鏈連接至貨物固持器6。第一部分14及第二部分15經朝向彼此折疊。特別是,第一鉸鏈13及呈可樞轉轉向機構27之形式的第二鉸鏈經置放使得可折疊框架2之第一部分14及第二部分15在經折疊狀態II中部分橫靠彼此延伸。另外或替代地,載貨自行車1可包含一第二鉸鏈,其將可折疊框架2之第二部分15鉸鏈連接至一第三部分,其中該第二鉸鏈可鎖定於各別伸長及經折疊狀態中(未展示)。舉例而言,此可有利地實施於兩輪載貨自行車1中以達成相同結果。Fig. 4 shows a simplified schematic top view of the cargo bicycle 1 of Fig. 3 in the folded state II. Here, it can be seen that the pivotable steering mechanism 27 acts as a second hinge that hinges the first part 14 of the foldable frame 2 to the cargo holder 6. The first part 14 and the second part 15 are folded toward each other. In particular, the first hinge 13 and the second hinge in the form of a pivotable steering mechanism 27 are placed so that the first part 14 and the second part 15 of the foldable frame 2 partially extend across each other in the folded state II . Additionally or alternatively, the cargo bicycle 1 may include a second hinge that hinges the second part 15 of the foldable frame 2 to a third part, wherein the second hinge can be locked in respective extended and folded states (Not shown).

如在其他實施例中,在可折疊框架2之經折疊狀態II中,將後輪4向旁邊置放。此處,轉向控制26 (特別是,車把)可由一使用者接取以用於將載貨自行車1作為一推車來推動。As in other embodiments, in the folded state II of the foldable frame 2, the rear wheel 4 is placed sideways. Here, the steering control 26 (especially, the handlebar) can be accessed by a user for pushing the cargo bicycle 1 as a cart.

圖6展示在經折疊狀態II中的載貨自行車1之一第四實施例(特別是,兩輪配置)之簡化示意性俯視圖。在經折疊狀態II中,可折疊框架2沿著載貨自行車1之縱向軸線5按一距離L2定位前輪3及後輪4。此處,前輪3提供於貨物固持器6之橫向側面7a之前部,以允許用於相對於可折疊框架2樞轉前輪3之空間。在彼處,用於支撐前輪3之輪支撐結構9 (特別是,前叉)可樞轉地配置於可折疊框架2上。前輪3之輪轂16可旋轉地安裝至前輪3之輪支撐結構9。轉向控制26 (特別是,車把)以技術人員已知之一方式經由可樞轉轉向機構27連接至前輪3之輪支撐結構9。由此,前輪3可藉由轉向控制26轉向。Figure 6 shows a simplified schematic top view of a fourth embodiment (in particular, a two-wheel configuration) of the cargo bicycle 1 in the folded state II. In the folded state II, the foldable frame 2 positions the front wheel 3 and the rear wheel 4 along the longitudinal axis 5 of the cargo bicycle 1 by a distance L2. Here, the front wheel 3 is provided in front of the lateral side 7a of the cargo holder 6 to allow space for pivoting the front wheel 3 with respect to the foldable frame 2. There, a wheel support structure 9 (especially, a front fork) for supporting the front wheel 3 is pivotally arranged on the foldable frame 2. The hub 16 of the front wheel 3 is rotatably mounted to the wheel support structure 9 of the front wheel 3. The steering control 26 (especially the handlebar) is connected to the wheel support structure 9 of the front wheel 3 via a pivotable steering mechanism 27 in a manner known to the skilled person. In this way, the front wheels 3 can be steered by the steering control 26.

後輪4之輪支撐結構9經由支柱鉸鏈11鉸鏈連接至可折疊框架2。如可在圖6中看出,在可折疊框架2之經折疊狀態II中,後輪4實質上橫向於載貨自行車1之縱向軸線5延伸,且至少部分與橫向延伸之面7重疊。此外,至少部分與橫向延伸之面7重疊的後輪4之輪轂16實質上處於由載貨自行車1之橫向邊界界定的封套17內。較佳地,後輪4之輪轂16處於由在載貨自行車1之縱向軸線5之任一側上延伸的橫向邊界之間的距離之四分之一界定的封套17'內,以允許在經折疊狀態中之緊湊構造。驅動系24包括一齒狀帶29以實現後輪4之輪支撐結構9的樞轉。The wheel support structure 9 of the rear wheel 4 is hingedly connected to the foldable frame 2 via a pillar hinge 11. As can be seen in FIG. 6, in the folded state II of the foldable frame 2, the rear wheel 4 extends substantially transversely to the longitudinal axis 5 of the cargo bicycle 1 and at least partially overlaps the transversely extending surface 7. In addition, the hub 16 of the rear wheel 4 at least partially overlapping the laterally extending surface 7 is substantially inside the envelope 17 defined by the lateral boundary of the cargo bicycle 1. Preferably, the hub 16 of the rear wheel 4 is within an envelope 17' defined by a quarter of the distance between the lateral boundaries extending on either side of the longitudinal axis 5 of the cargo bicycle 1 to allow the Compact structure in state. The drive train 24 includes a toothed belt 29 to realize the pivoting of the wheel support structure 9 of the rear wheel 4.

在此實施例中,將可折疊框架2之基底部分21圍繞可折疊框架2之伸縮部分22配置為一套管,使得伸縮部分22可滑動穿過基底部分21。伸縮部分22在伸長狀態I與經折疊狀態II之間及在經折疊狀態II與伸長狀態I之間沿著縱向軸線5相對於基底部分21可滑動。可提供一鎖定機構,其將可折疊框架2鎖定於各別伸長狀態I及經折疊狀態II中之各者中。為了將可折疊框架2滑動至伸長狀態I,伸縮部分22滑出基底部分21。隨後,圍繞座管鉸鏈28將座管19豎直地疊起至疊出位置α,且接著圍繞支柱鉸鏈11使輪支撐結構9及後輪4樞轉以沿著載貨自行車1之縱向軸線5延伸。較佳地,後輪4之輪支撐結構9藉由一緊固機構緊固至可折疊框架2。較佳地,載貨自行車1之兩輪配置亦包含具有支撐輪31之一可收縮支撐總成30,以提供在可折疊框架2之經折疊狀態II中的穩定性。在此情況中,在框架之經折疊狀態II中的載貨自行車1可作為具有一可轉向前輪3之推車操作。In this embodiment, the base portion 21 of the foldable frame 2 is configured as a sleeve around the telescopic portion 22 of the foldable frame 2 so that the telescopic portion 22 can slide through the base portion 21. The telescopic portion 22 is slidable relative to the base portion 21 along the longitudinal axis 5 between the extended state I and the folded state II and between the folded state II and the extended state I. A locking mechanism can be provided that locks the foldable frame 2 in each of the respective extended state I and the folded state II. In order to slide the foldable frame 2 to the extended state I, the telescopic part 22 slides out of the base part 21. Subsequently, the seat tube 19 is vertically folded around the seat tube hinge 28 to the folded out position α, and then the wheel support structure 9 and the rear wheel 4 are pivoted around the pillar hinge 11 to extend along the longitudinal axis 5 of the cargo bicycle 1 . Preferably, the wheel support structure 9 of the rear wheel 4 is fastened to the foldable frame 2 by a fastening mechanism. Preferably, the two-wheel configuration of the cargo bicycle 1 also includes a retractable support assembly 30 having a support wheel 31 to provide stability in the folded state II of the foldable frame 2. In this case, the cargo bicycle 1 in the folded state II of the frame can be operated as a cart with a steerable front wheel 3.

另外或替代地,在經折疊狀態II中,前輪3可橫向於載貨自行車1之縱向軸線5延伸,且至少部分與橫向延伸之面7重疊。以此方式,可將前輪3折疊,且前輪3之一側面及/或前輪3之輪支撐結構9可至少部分沿著橫向延伸之面7置放。在此情況中,可提供具有支撐輪31之另一可收縮支撐總成30,以允許將在可折疊框架2之經折疊狀態II中的載貨自行車1用作一推車。Additionally or alternatively, in the folded state II, the front wheel 3 may extend transversely to the longitudinal axis 5 of the cargo bicycle 1 and at least partially overlap the transversely extending surface 7. In this way, the front wheel 3 can be folded, and a side surface of the front wheel 3 and/or the wheel support structure 9 of the front wheel 3 can be placed at least partially along the laterally extending surface 7. In this case, another collapsible support assembly 30 with support wheels 31 may be provided to allow the cargo bicycle 1 in the folded state II of the foldable frame 2 to be used as a cart.

在圖3至圖6中,支柱鉸鏈11提供於後下叉部件(上部及下部)上,且經由支柱鉸鏈11將輪支撐結構9連接至可折疊框架2之其餘部分。亦即,支柱鉸鏈11將後上叉部件及後下叉部件鉸鏈耦接至可折疊框架2之其餘部分。支柱鉸鏈定位於後輪4之一輪轂與載貨自行車1之一座管之間。藉由更朝向輪轂定位支柱鉸鏈,可達成,在可折疊框架之經折疊狀態中,輪中之至少一者橫向於載貨自行車之縱向軸線延伸,且至少部分與橫向延伸之面重疊。由此,在經折疊狀態中,可實現一緊湊構造,特別是,其相對易於操作及在各別伸長狀態與經折疊狀態之間調整。替代地,輪支撐結構9可例如包含僅一後下叉部件或一後上叉部件(亦即,分別無後上叉部件或後下充滿部件),或前輪之一叉頭,該叉頭經由一支柱鉸鏈鉸鏈耦接至可折疊框架之其餘部分。In FIGS. 3 to 6, the pillar hinge 11 is provided on the chainstay parts (upper and lower), and the wheel support structure 9 is connected to the rest of the foldable frame 2 via the pillar hinge 11. That is, the pillar hinge 11 couples the seat stay and the chain stay hinge to the rest of the foldable frame 2. The pillar hinge is positioned between a hub of the rear wheel 4 and a seat tube of the cargo bicycle 1. By positioning the pillar hinge further toward the hub, it can be achieved that in the folded state of the foldable frame, at least one of the wheels extends transversely to the longitudinal axis of the cargo bicycle and at least partially overlaps the transversely extending surface. Thus, in the folded state, a compact structure can be realized, and in particular, it is relatively easy to handle and adjust between the respective extended state and the folded state. Alternatively, the wheel support structure 9 may include, for example, only one chainstay member or a seatstay member (that is, no seatstay member or underfill member respectively), or a fork head of the front wheel through A pillar hinge hinge is coupled to the rest of the foldable frame.
