上記の特許文献１〜３に開示された手すり用ブラケットは、それぞれが固有の課題を解決した構成であり、特徴的な作用、効果を奏するものと認められる。
しかしながら、敢えて言えば、特許文献１に開示された手すり用ブラケットは、固定板と支持板とのピンジョイント部分が緩んで軟弱になりがちと認められる。そのため支持した手すりがぐらぐらと揺れ動き易く、この手すりに掴まって歩く人の安心感、信頼感を得難く、歩行を助ける実効性が低いように認められる。 Each of the handrail brackets disclosed in Patent Documents 1 to 3 has a configuration in which each of the unique problems is solved, and is recognized to exhibit characteristic actions and effects.
However, daringly speaking, it is recognized that the handrail bracket disclosed in Patent Document 1 tends to become loose because the pin joint portion between the fixing plate and the support plate is loosened. For this reason, the supported handrails are swaying and swinging easily, and it is recognized that it is difficult to obtain the sense of security and reliability of the person who walks by grabbing the handrails, and the effectiveness of assisting walking is low.

特許文献２に開示された手すり材取付用ブラケットは、手すり材の支持方向や角度の自在性を持たない構成であるから、使い勝手が悪く、適用範囲が狭い。
特許文献３に開示された手すり材取付用ブラケットは、固定板と、手すり材を支持する支持板とを回転可能に連結した構造が、特許文献１のブラケットよりも頑丈な構成と認められる。しかし、固定板および支持板の構造、並びに両者の連結構造がいかにも複雑である。また、構成部品の点数が多いので、製作に手数が掛かり、高価なものと認められる。 Since the handrail material mounting bracket disclosed in Patent Document 2 has a configuration that does not have flexibility in the support direction and angle of the handrail material, it is not easy to use and has a narrow application range.
In the handrail material mounting bracket disclosed in Patent Document 3, a structure in which a fixed plate and a support plate that supports the handrail material are rotatably connected is recognized as being more robust than the bracket of Patent Document 1. However, the structure of the fixing plate and the support plate, and the connection structure between them are extremely complicated. Further, since the number of component parts is large, it takes a lot of work to manufacture, and is recognized as expensive.

本発明の目的は、構成が簡単で、構成部品の点数が少なく、製作が容易であり、安価に製造できる、手すり設置用の自在ブラケットを提供することである。
本発明の次の目的は、手すり支持部材の軸部と、ベース部材の軸孔の構成とを共通させるかぎり、ベース部材を共通に使用して様々なソケット形状の手すり支持部材を必要に応じて選択し使用することができ、使用の自由度、適用範囲が広い、手すり設置用の自在ブラケットを提供することである。 An object of the present invention is to provide a universal bracket for installing a handrail that has a simple configuration, has a small number of component parts, is easy to manufacture, and can be manufactured at low cost.
As long as the shaft portion of the handrail support member and the configuration of the shaft hole of the base member are made common, the present invention aims to use various types of socket-shaped handrail support members as needed. It is to provide a universal bracket for handrail installation that can be selected and used, has a wide range of freedom of use, and a wide range of applications.

本発明の更なる目的は、設置対象が壁や柱である場合はもとより、特には壁面から幅狭くせり出した柱の露出側面へも設置可能であり、このような柱の露出側面へ設置することにより手すりが壁面から室内側へ突き出す寸法の縮小化を達成できる、手すり設置用の自在ブラケットを提供することである。
本発明は、手すり材を壁面と平行な方向に、しかも床面に対して任意所望の角度に傾斜させて設置することができ、手すり設置計画の自由度が高い、手すり設置用の自在ブラケットを提供することも目的としている。 A further object of the present invention is not only when the installation target is a wall or a pillar, but also particularly on the exposed side surface of a pillar protruding narrowly from the wall surface. It is intended to provide a universal bracket for installing a handrail that can achieve a reduction in the size of the handrail protruding from the wall surface to the indoor side.
The present invention provides a universal bracket for handrail installation, which can be installed by tilting the handrail material in a direction parallel to the wall surface and at an arbitrary desired angle with respect to the floor surface, and has a high degree of freedom in handrail installation planning.

Is perpendicular with respect to the front face, the back of the seating surface 10 As will be described later, one is provided in a direction that is non-vertical and inclined at a certain angle .
More specifically, as shown in the enlarged view of FIG. 5B, induction bore hole 12 of the base member 2 is a non-perpendicular to the seating surface 10, the axis e of the socket portion 3 of the handrail supporting member 1 and substantially Inclined at a certain angle in the parallel direction. Its meaning base by wood screws 14 screwed firm support of the handrail member b which respect the floor is placed inclined at a prescribed angle to the vertical direction, the pillar d through Toriwa only induced bore hole 12 as shown in FIG. 5A The support / fixed state of the member 2 is the most stable and effective state (the invention described in claim 4).

ベース部材２の上記軸孔８の内周面には、上記手すり支持部材１の軸部５に設けられた突起７を軸線方向へ通す縦溝１５が形成されている。また、軸部５の上端の回転座面６が軸孔８の上端面１６へ図３のように着座すると突起７が到達する深さ位置に、前記溝１５を通過した突起７が回転することを許容し、且つ抜け止め作用を奏する円周方向の段差面１７が形成されている（図３と図７を参照）。段差面１７より下方はそのまま大径の貫通孔に形成されている。 A longitudinal groove 15 is formed on the inner peripheral surface of the shaft hole 8 of the base member 2 to pass the projection 7 provided on the shaft portion 5 of the handrail support member 1 in the axial direction. Further, when the rotary seat surface 6 at the upper end of the shaft portion 5 is seated on the upper end surface 16 of the shaft hole 8 as shown in FIG. 3, the projection 7 that has passed through the groove 15 rotates to a depth position where the projection 7 reaches. And a stepped surface 17 is formed in the circumferential direction that exhibits a retaining action (see FIGS. 3 and 7). The portion below the step surface 17 is formed as a large-diameter through hole as it is.

要するに本実施例のブラケットａの使用法としては、先ずベース部材２を、手すりの設置対象である図５Ａに示す柱ｄの露出側面ｄ’に対して、取付け部１１の着座面１０を図５Ｂ及び図５Ｃのように密着させ、ネジ誘導孔１２へ通した固定具としての木ねじ１４を前記柱ｄへねじ込んで固定する。本実施例のベース部材２は、取付け部１１および着座面１０を、壁面から幅狭く露出した柱ｄの露出側面ｄ’へ全面一様に接する大きさ、形状に可及的に小さく設けており、柱ｄの露出側面ｄ’へ十分強固に固定できる。したがって、柱ｄの前面へ取り付ける場合に比して、壁面から手すり材ｂが突き出る寸法を縮小化できる。勿論、ベース部材２は、図３に例示したように、壁面ｃ或いは柱ｄの前面へ着座面１０を密接させた状態にも取り付け固定できるのであり、手すりの設置場所を壁ｃや柱ｄの側面など多様に選択して使用できる便利さ、使い勝手の良さがある。固定具としては前記木ねじ１４が代表的であるが、釘類やセルフタップビスなどを使用することもできる。この点は以下の各実施例にも共通する。 In short, as a method of using the bracket a of the present embodiment, first, the base member 2 is placed on the seating surface 10 of the mounting portion 11 with respect to the exposed side surface d ′ of the column d shown in FIG. Further, as shown in FIG. 5C, the wood screw 14 as a fixture passed through the screw guide hole 12 is screwed into the column d and fixed. In the base member 2 of this embodiment, the mounting portion 11 and the seating surface 10 are provided as small as possible in size and shape so as to be in uniform contact with the exposed side surface d ′ of the column d exposed narrowly from the wall surface. It can be fixed sufficiently firmly to the exposed side surface d ′ of the column d. Therefore, compared with the case where it attaches to the front surface of the pillar d, the dimension which the handrail material b protrudes from a wall surface can be reduced. Of course, as illustrated in FIG. 3 , the base member 2 can be mounted and fixed in a state where the seating surface 10 is in close contact with the front surface of the wall surface c or the column d. Convenient and convenient to use by selecting various aspects such as side. The wood screw 14 is representative as a fixture, but nails, self-tapping screws, and the like can also be used. This point is common to the following embodiments.

一方、手すり支持部材１は、その軸部５を前記ベース部材２の軸孔８へ、その突起７と縦溝１５の位置とを整合させて差し込み、回転座面６が軸孔８の上端面１６へ突き当たり着座した段階で回転させることにより、軸部５の突起７を段差面１７へ掛け止めて抜け止めが行われる。そして、前記抜け止め状態でソケット部３を手すり材ｂの設置方向の角度に設定して使用する。したがって、外観意匠はシンプルでスマートであり、従来技術のように、連結箇所にボルトやピンが露出する見栄えの悪さはない（図２参照）。
手すり支持部材１のソケット部３は、軸部５の突起７が、ベース部材２の軸孔８における縦溝１５の位置から段差面１７へ移動して掛け止められ抜け止め作用が奏されている角度範囲（図４の角度α）であるかぎり、自由に任意所望の手すり設置角度に設定して使用することができる。 On the other hand, the handrail support member 1 is inserted into the shaft hole 8 of the base member 2 with the projection 7 and the longitudinal groove 15 being aligned, and the rotary seat surface 6 is the upper end surface of the shaft hole 8. By rotating at the stage where it abuts against 16 and is seated, the projection 7 of the shaft portion 5 is hooked on the stepped surface 17 to prevent it from coming off. And the socket part 3 is set and used for the angle of the installation direction of the handrail material b in the said retaining state. Accordingly, the appearance design is simple and smart, and there is no bad appearance in which the bolts and pins are exposed at the connection places as in the prior art (see FIG. 2).
Socket 3 of the handrail supporting member 1, the projection 7 of the shaft portion 5, the position omission is hooked by moving the stepped surface 17 from stopping the action of the longitudinal groove 15 in the shaft hole 8 of the base member 2 is achieved As long as it is in the angle range (angle α in FIG. 4), it can be freely set to any desired handrail installation angle.

上記のような使用態様を前提として、請求項６に記載した発明では、手すり支持部材１の軸部５の突起７が、例えば図１に示したように、ソケット部３の軸線ｅを平面的に見た位置関係として約９０°隔てた方向に１８０°対称な配置で２個（但し、１個でも可）設けられている。一方、ベース部材２の軸孔８における縦溝１５を平面的に見た位置は、図４に矢印Ｆで示した手すり設置方向と同一の向きに設けられている。したがって、手すり支持部材１のソケット部３は、手すり材ｂの設置方向（矢印Ｆ）を中心として約９０°の角度範囲αでは、必ず軸部５の突起７が、ベース部材２の軸孔８における段差面１７による抜け止め作用を受けて安全に使用できる角度範囲として使用可能であり、手すり設置角度の自由度が高い。 In the invention described in claim 6 on the premise of the use mode as described above, the projection 7 of the shaft portion 5 of the handrail support member 1 is flat with the axis e of the socket portion 3 as shown in FIG. As shown in FIG. 2, two (but only one) are provided in a symmetrical arrangement of 180 ° in a direction separated by about 90 °. On the other hand, the position of the longitudinal groove 15 in the shaft hole 8 of the base member 2 as viewed in plan is provided in the same direction as the handrail installation direction indicated by the arrow F in FIG. Therefore, the socket portion 3 of the handrail support member 1 always has the projection 7 of the shaft portion 5 in the shaft hole 8 of the base member 2 in an angle range α of about 90 ° with respect to the installation direction (arrow F) of the handrail material b. Can be used as an angle range that can be used safely by receiving the retaining action by the stepped surface 17 and has a high degree of freedom in the handrail installation angle.

本実施例のブラケットａを用いて手すり材ｂを設置するには、図５Ａ〜Ｄに例示したように、先ずベース部材２の着座面１０を設置面へ密着させ木ねじ１４で固定する。このベース部材２の軸孔８へ、手すり支持部材１の軸部５を差し込み回転して、突起７がベース部材２の軸孔８における段差面１７で抜け止め作用を受ける状態とし、ソケット部３を手すり設置方向の角度に設置する。前記のようにして２個のブラケットａ、ａを設置し、これら２個のブラケットａ、ａの有効間隔よりも少し短めの手すり材ｂの両端部を交互に各ソケット部３へ嵌め込み略等分の長さ支持させる。そして、各ソケット部３の外筒部に予め設けてあるネジ孔１８へ止めネジ１９をねじ込み、各ソケット部３と手すり材ｂとを強固に結合する。 In order to install the handrail material b using the bracket a of the present embodiment, the seating surface 10 of the base member 2 is first brought into close contact with the installation surface and fixed with the wood screws 14 as illustrated in FIGS.

Is installed at an angle in the direction of handrail installation. As described above, the two brackets a and a are installed, and both ends of the handrail material b slightly shorter than the effective interval between the two brackets a and a are alternately fitted into the respective socket portions 3 to be substantially equally divided. Support the length of. Then, a set screw 19 is screwed into a screw hole 18 provided in advance in the outer cylinder portion of each socket portion 3 to firmly bond each socket portion 3 and the handrail material b.

本実施例において、手すり支持部材１の軸部５の突起７を矩形断面に設けた理由は、上述したように、突起７を縦溝１５へ通過させ、更に段差面１７の方向へ回転させて抜け止めを行う上で効率のよい断面形状という意味である。したがって、突起７を矩形断面以外の例えば丸断面等に設けた構成で実施しても良い。 In this embodiment, the reason why the projection 7 of the shaft portion 5 of the handrail support member 1 is provided in a rectangular cross section is that, as described above, the projection 7 is passed through the vertical groove 15 and further rotated in the direction of the stepped surface 17. This means that the cross-sectional shape is efficient in preventing the removal. Therefore, you may implement by the structure which provided the processus | protrusion 7 in round cross sections etc. other than a rectangular cross section.

図６は、手すり支持部材１’のソケット部３’の形態が異なる実施例を示す。即ち、上記図１の実施例１における手すり支持部材１のソケット部３は、開口とは反対側の後端側が絞り尾部４により完全に閉鎖された片開口の形態（図３も参照）であるが、本実施例２のソケット部３’は、完全に貫通した中空円筒形状であり、その円筒外壁からソケット部３’の軸線と直角方向へ延びる軸部５が設けられている。従って、本実施例のブラケットは、長い手すり材ｂの中間部を支持する部材として便利に使用できる。
本実施例のブラケットに使用するベース部材２の構成は、上記実施例１と同一の構成であり、要するにベース部材２には互換性があり、共通に使用できる構成である。
ソケット部の形状、構造としては、Ｃ字形状に一部開放された形状でも良いし、或いは非円形の例えば多角形状等であってもよい。 FIG. 6 shows an embodiment in which the shape of the socket portion 3 ′ of the handrail support member 1 ′ is different. That is, the socket portion 3 of the handrail support member 1 in the embodiment 1 of FIG. 1 is in the form of a single opening in which the rear end side opposite to the opening is completely closed by the aperture tail portion 4 (see also FIG. 3). However, the socket part 3 ′ of the second embodiment has a completely hollow cylindrical shape, and a shaft part 5 extending from the outer wall of the cylinder in a direction perpendicular to the axis of the socket part 3 ′ is provided. Therefore, the bracket of the present embodiment can be conveniently used as a member that supports the middle portion of the long handrail material b.
The structure of the base member 2 used for the bracket of the present embodiment is the same as that of the first embodiment. In short, the base member 2 is compatible and can be used in common.
The shape and structure of the socket portion may be a shape that is partially opened in a C shape, or may be a non-circular shape such as a polygonal shape.

図８は、請求項３に記載した発明３に係る手すり設置用自在ブラケットの実施例を示している。このブラケットも構成の多くが、上記実施例１のブラケットと共通するので、共通部分の説明は省略する場合があることを前置きして、以下の説明を行う。
本実施例のブラケットも、手すり支持部材１と、取付用のベース部材２とからなる。各々はやはりアルミニュームのダイキャスト製品として製作されている。 FIG. 8 shows an embodiment of a handrail installation universal bracket according to the third aspect of the present invention. Since many of the configurations of this bracket are the same as those of the bracket of the first embodiment, the following description will be given with an introduction that the description of the common portions may be omitted.
The bracket of this embodiment also includes a handrail support member 1 and a base member 2 for mounting. Each is also made as an aluminum die-cast product.

本実施例の手すり支持部材１も、手すり材を支持するソケット部３と、ソケット部３の軸線と直角方向へ延びる軸部５とで構成され、軸部５の上端に回転座面６が段差面状に形成されている。
本発明３の特徴は、手すり支持部材１の軸部５が基本的に均等断面の棒状体であり、突起も溝も設けられていないことである。但し、図８に示した実施例の場合、上記の実施例１に倣う形に軸部５の先端部外周に突起７を形成しているが、この点には技術的にさしたる意味がなく、付記的事項に過ぎない。 The handrail support member 1 of the present embodiment also includes a socket portion 3 that supports the handrail material and a shaft portion 5 that extends in a direction perpendicular to the axis of the socket portion 3. It is formed in a planar shape.
The feature of the third aspect of the present invention is that the shaft portion 5 of the handrail support member 1 is basically a rod-shaped body having a uniform cross section, and no protrusions or grooves are provided. However, in the case of the embodiment shown in FIG. 8, the protrusion 7 is formed on the outer periphery of the tip portion of the shaft portion 5 in a shape similar to that of the first embodiment, but this point has no technical significance. It is only an additional matter.

ベース部材２の基本形状も、上記実施例１〜３と同様であり、上記手すり支持部材１の軸部５を挿入するほぼ同径の軸孔８を備えている。この軸孔８を形成した主部９の低部両側に、図５の壁ｃ又は柱ｄ等の設置面へ全面一様に接する着座面１０を形成した取付け部１１が設けられ、この取付け部１１には前記着座面１０に向かって貫通するネジ誘導孔が設けられている構成には変わりない。 The basic shape of the base member 2 is also the same as in the first to third embodiments, and includes a shaft hole 8 having substantially the same diameter into which the shaft portion 5 of the handrail support member 1 is inserted. On both sides of the lower portion of the main portion 9 in which the shaft hole 8 is formed, there are provided mounting portions 11 each having a seating surface 10 that uniformly contacts the installation surface such as the wall c or the column d shown in FIG. 11 does not change to a configuration in which a screw guide hole penetrating toward the seating surface 10 is provided.

本発明３の特徴は、上記主部９の軸孔８は均等断面の単純孔でよく、突起も溝も設けられていないことである。但し、主部９には、前記軸孔８に向かって貫通するネジ孔３０が設けられ、これに止めネジ３１がねじ込まれる構成である。図８の実施例の場合、軸孔８には、上記手すり支持部材１の軸部５の突起７に対応する形に、同突起７を通過させる縦溝が段差面１７まで形成されているが、その図示は省略している。前記縦溝も、やはり付記的事項に過ぎない。 The feature of the present invention 3 is that the shaft hole 8 of the main portion 9 may be a simple hole having a uniform cross section, and no projections or grooves are provided. However, the main portion 9 is provided with a screw hole 30 penetrating toward the shaft hole 8, and a set screw 31 is screwed into the screw hole 30. In the case of the embodiment of FIG. 8, the shaft hole 8 is formed with a vertical groove that passes through the projection 7 up to the step surface 17 in a shape corresponding to the projection 7 of the shaft portion 5 of the handrail support member 1. The illustration is omitted. The longitudinal groove is also an additional matter.

本実施例４の場合も、ベース部材２は、取付け部１１の着座面１０を例えば図５の壁ｃ又は柱ｄ等の設置面へ密着させ、ネジ誘導孔へ通した木ねじ等の固定具を前記設置面へねじ込むなどして固定する。手すり支持部材１は、その軸部５を前記ベース部材２の軸孔８へ差し込み、ソケット部３を手すり設置方向の角度に設置する。
本実施例の場合、手すり支持部材１の軸部５は、ベース部材２の軸孔８に対して、図８に示す許容ストローク範囲Ｓの限度に軸方向にスライドさせることができる。よって、着座面１０（又は設置面）からソケット部３の軸心までの距離を任意に出入り調整して、ソケット部３の出入り調整を確定した段階で、主部９のネジ孔３０へ止めネジ３１をねじ込み、軸部５を強固に固定して使用するのである。 Also in the case of the fourth embodiment, the base member 2 is provided with a fixing tool such as a wood screw that has the seating surface 10 of the mounting portion 11 in close contact with the installation surface such as the wall c or the column d in FIG. Fix by screwing into the installation surface. The handrail support member 1 has its shaft portion 5 inserted into the shaft hole 8 of the base member 2, and the socket portion 3 is installed at an angle in the handrail installation direction.
In the case of the present embodiment, the shaft portion 5 of the handrail support member 1 can be slid in the axial direction with respect to the shaft hole 8 of the base member 2 within the limit of the allowable stroke range S shown in FIG. Therefore, when the distance from the seating surface 10 (or the installation surface) to the axial center of the socket part 3 is arbitrarily adjusted to enter and exit, and the adjustment of the entrance and exit of the socket part 3 is confirmed, the set screw is inserted into the screw hole 30 of the main part 9. 31 is screwed and the shaft portion 5 is firmly fixed for use.

なお、上記実施例４と同様に、上記発明１及び２の実施例１〜３に関しても、その主部９に、軸孔８に向かって貫通するネジ孔（３０）を設け、同軸孔８へ差し込まれた手すり支持部材１の軸部５のソケット部３を手すり設置方向の角度に設置した段階で、主部９のネジ孔へねじ込んだ止めネジ（３１）で固定する構成で実施することも好ましい（請求項５に記載した発明）。 As in the fourth embodiment, also in the first to third embodiments of the inventions 1 and 2, the main portion 9 is provided with a screw hole (30) penetrating toward the shaft hole 8 to the coaxial hole 8. It is also possible to carry out a configuration in which the socket portion 3 of the shaft portion 5 of the inserted handrail support member 1 is fixed with a set screw (31) screwed into the screw hole of the main portion 9 at the stage where the socket portion 3 is installed at an angle in the handrail installation direction. Preferred (the invention described in claim 5).
