Japanese Patent No. 4106233 JP 2003-28130 A

  The retractable hook device particularly emphasizes safety and appearance, but has the following restrictions on usability. For example, in recent years, there are an increasing number of people who keep pets such as dogs and cats, and the number of pets in cars is increasing for shopping. Pets are usually brought into the passenger compartment in a state where they can be restrained by a mooring string connected to a collar. In the passenger compartment, the pet is preferably hooked on a hook device provided on the seat or the inner side wall using a connecting tool such as an eggplant provided on the terminal of the mooring string. However, the hook member has a J shape in a side view, and it is easy to hook a bag or a hanger on the one end side hook portion, but it is difficult to attach or detach a connecting tool such as an eggplant.

  In Japanese Patent No. 3911224, the hook device is not a type in which a hook member is housed in a case, but includes a base body and an annular hook body, and a groove for hanging a bag or a hanger provided on the base body. There is disclosed a device including a hook portion having a ring shape and a ring portion that is provided on an annular hook body and hooks a hook or the like. In this structure, when the annular hooking body is unnecessary, it can be rotated and assembled to the base body, but the groove-like hooking part is provided on the upper part and the side part of the base body and opened outward. Therefore, it is harder to hook a bag or hanger than a J-shaped hook, and since the annular hook is a ring part, it is difficult to attach and detach a connecting tool such as an eggplant. Also, for example, even if the anchoring string of the mooring string can be connected to the annular hook body, safety is sacrificed because the annular hook body is rotated and protrudes from the base body.

  Accordingly, an object of the present invention is to enable a bag or a hanger to be hung from a hook member with a minimum number of parts in a retractable hook device, and to be able to hang a connection tool such as an eggplant in the hook member retracted state. It is to improve usability.

  In order to achieve the above object, the present invention can be switched between a case opened at the front side, a retracted state in which the hook portion is pivotally supported by the case and housed in the case, and a use state protruding outside the case. In the hook device provided with a hook member, the hook member is substantially J-shaped in a side view, and protrudes into one end side of the main body that is substantially contained in the case in both the storage state and the use state. It is characterized by having a support shaft portion that is formed of the hook portion provided and that is disposed so as to be within the thickness of the main body and capable of hooking a connecting tool such as an eggplant.

The present invention as described above is more preferably embodied as described in claims 2-5. That is, (a) The main body has a substantially frame shape, and the support shaft portion is arranged in the frame shape (Claim 2).
(B) The support shaft portion also serves as a shaft member that pivotally supports the hook member on the case (Claim 3).

(C) The support shaft portion is formed integrally with the main body (Claim 4).
(D) The hook member is configured to be inverted by approximately 180 degrees with a substantially middle portion between the upper and lower sides as a fulcrum in the case (Claim 5).

  In the invention of claim 1, in addition to hanging an article such as a bag or a hanger on one end side hook portion (substantially J-shaped tip side) in the use state of the hook member as illustrated in FIG. As illustrated in (a), the connecting member such as the eggplant provided at the end of the mooring string as described above can be hooked on the support shaft portion regardless of whether the hook member is stored or used. it can. In addition, since the support shaft portion is provided so as to be within the thickness of the main body, which is always within the case among the hook members, as shown in FIG. When a connecting tool such as an eggplant is hooked in the retracted state, there is no protrusion from the case, which is excellent in terms of usability and safety.

  In the invention of claim 2, since the main body of the hook member has a substantially frame shape, and the support shaft portion is disposed in the frame shape frame, when the connecting tool such as an eggplant is hooked on the support shaft portion, Good operability can be maintained due to the presence of the inner space.

  In the invention of claim 3, since the support shaft portion also serves as a shaft member that pivotally supports the hook member on the case as exemplified in FIGS. 1 to 4, the member configuration is at least a case and a hook member. The three-point configuration of the support shaft is simplified. On the other hand, in the invention of claim 4, compared to claim 3, the number of members can be reduced if the support shaft portion is formed integrally with the hook member as illustrated in FIGS. Of course, the support shaft portion of the present invention is not limited to the structure of claims 3 and 4 and can be configured by a dedicated shaft member independent of the shaft member for shaft support.

  According to the fifth aspect of the present invention, the hook member rotates about 180 degrees forward / reverse or reverses about 180 degrees around the upper and lower intermediate portions as in the form of the embodiment to switch from the stored state to the used state or from the used state to the stored state. Compared to the conventional type that rotates approximately 90 degrees, the amount of overhang from the case side can be easily suppressed with stable switching operability.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. This description will be described in detail in the order of the device structure, assembly and main operation, and modification.

(Device Structure) The hook device of the embodiment can be switched between a case 1 having an opening on the front side, a retracted state that is pivotally supported by the case 1 and enters the case, and a use state in which the tip side hook portion 21 protrudes outside the case. A hook member 2, a shaft member that pivotally supports the hook member 2 on the case 1, and a shaft 3 that also serves as a support shaft portion of the present invention are provided.

  The hook device is designed to be attached to the back side of the seat back of the seat in the vehicle interior. However, the hook device may be attached to the side wall of the seat or the wall of the vehicle interior other than the seat. Reference numeral 4 in FIG. 1 assumes a panel or bracket for attaching the hook device to the attached surface (in this example, the back of the seat back).

  The case 1 is made of a resin molded product and has a container shape with a front opening as shown in FIGS. 2 and 4, and includes a front edge portion 10, a container body 11 behind the edge portion 10, and a container body 11. It consists of upper and lower engaging portions 12A, 12B provided on the rear outer wall. The case is a substantially rectangular solid space. Of these, the engaging portions 12A and 12B are configured to engage with a locking hole (not shown) provided in the bracket 4 as shown in FIG. As shown in FIGS. 1 and 4, the engaging portion 12A includes an elastic engaging claw 12a provided on the upper side and defined by a U-shaped slit 12b, and ribs 12c provided on both sides. The engaging portion 12B is composed of a pair of elastic locking pieces. Of course, the configuration of the engaging portions 12A and 12B is changed as necessary.

  Both inner side walls 13 are provided with shaft holes 17 on the front side and penetrating on the coaxial line. On one side surface (right side surface) of the edging portion 10, a relief cutout portion 18 communicating with the corresponding shaft hole 17 is provided. The front side 14a of the upper inner wall 14 is greatly thinned outward as compared to the back side, and is connected to the back side via an inclined front / rear intermediate part 14b. The front side 14a and the front / rear intermediate portion 14b are in contact with the one end side hook portion 21 of the hook member 2 with appropriate strength. The lower inner wall 15 is provided with a substantially U-shaped locking groove 16 at the approximate center. The locking groove 16 includes an intermediate lateral groove 16a formed through and front and rear grooves 16b on both sides. Of these, the front and rear grooves 16 b function as substantial locking grooves 16.

  On the other hand, the hook member 2 is made of a resin molded product, has a substantially J shape in side view as shown in FIG. More specifically, the hook member 2 includes a substantially rectangular frame-shaped main body 20 and a hook portion 21 provided on one end side (front end side) of the main body 20. The main body 20 has a shaft hole 23 formed on both sides of the frame shape and having substantially the upper and lower intermediate portions formed on the coaxial line, and a pair of protrusions 24 (in FIG. Only the projection 24 is shown). The main body 23 is almost contained in the case in the retracted state in which the entire hook member 2 is accommodated in the case 1 and in the usage state in which the hook portion 21 is projected out of the case. The hook portion 21 is formed in a loose arc shape. The hook portion 21 is in pressure contact with the front side 14a and the front / rear intermediate portion 14b constituting the upper inner wall 14 of the case 1 in a retracted state in which the hook member 2 is accommodated in the case 1 as shown in FIG. It is formed with curvature.

(Assembly and main operation) The case 1 and the hook member 2 described above are assembled as follows. That is, the hook member 2 is placed in the case 1 and positioned so that each shaft hole 23 overlaps the corresponding shaft hole 17 on the case side. From this state, the hook member 2 is inverted 180 degrees with respect to the case 1 by inserting the shaft portion 31 of the shaft 3 into the right shaft hole 17 and the shaft hole 23 and the left shaft hole 23 and the shaft hole 17. The hook device is assembled as possible. In this assembled state, the tip of the shaft portion 31 is engaged with the left shaft hole 17 to prevent the shaft 3 from coming off, and the head portion 30 fits in the case-side escape notch portion 18 in an attractive manner. The hook device is attached to the seat back side frame of the seat via the panel or bracket 4 as shown in FIG. Operationally, the following advantages can be obtained.

(1) The hook device includes the hook member 2 in the retracted state of FIG. 1A in which the protrusions 24 abut against the groove ends of the locking grooves 16 (front and rear grooves 16b) with respect to the case 1, and 1B is reversed about 180 degrees with the shaft portion 31 of the shaft 3 as a fulcrum to the use state of FIG. In this structure, the hook member 2 is inverted approximately 180 degrees with the shaft portion 31 as a fulcrum, so that it is easier to suppress the amount of protrusion from the case 1 in use compared to a conventional configuration that rotates, for example, 90 degrees, It becomes easy to reduce the size of the storage space.

(2) Of course, in the retracted state, the tip side hook portion 21 is stably held in the retracted state by being pressed against the front side 14a and the front / rear intermediate portion 14b constituting the upper inner wall 14 as shown in FIG. The In the use state, the back surface side of the hook portion 21 abuts on the front surface portion of the case side edging portion 10 and is in pressure contact with the front side 14a and the front / rear intermediate portion 14b of the upper inner wall 14, so that the use state is stably maintained.

(3) In the use state, the article 6 such as a bag or a hanger can be suspended from the one end side hook part (substantially J-shaped tip side) 21. In addition, the hook 5 can be hooked with the connecting member 5 such as the eggplant provided on the end of the anchoring string on the shaft portion 31 on the side of the main body 2 regardless of whether the hook member 2 is stored or used. it can. Since the shaft portion 31 is provided in the hook member 2 so as to be within the thickness of the main body 20 that is always within the case 1, that is, so as not to protrude from the main body, Since it is arranged in the frame shape of the main body, when the connecting member 5 such as an eggplant is hooked in the retracted state of the hook member 2 as shown in FIG. It is excellent in terms of usability and safety.

(4) In this structure, the shaft 3 serves as both the shaft member that pivotally supports the hook member 2 on the case 1 and the support shaft portion of the present invention. Since it can be constituted by three points of the member 2 and the shaft 3, it is simplified.

(Modification) FIG. 5 and FIG. 6 show another configuration example of the shaft 3. 5 corresponds to FIG. 2, and FIG. 6 corresponds to FIG. In this description, members that are the same as or similar to those in the above-described embodiment are given the same reference numerals, and only the changed configuration will be described in detail.

  That is, in this modification, the main body 20 includes a support shaft portion 25 that is integrally formed in a state of being coupled to both inner surfaces of the frame, and a shaft portion 26 that projects from both outer surfaces of the frame. The support shaft portion 25 is horizontally disposed at a substantially intermediate position in the upper and lower sides in the main body frame. As shown in FIG. 6A, the support shaft portion 25 is hung with a connecting tool 5 such as an eggplant provided on the end of the mooring string as described above. Can be stopped. The shaft portion 26 protrudes at a substantially intermediate position in the vertical direction outside the main body frame, and pivotally supports the hook member 2 with respect to the case 1 by fitting in the case side shaft hole 17a. In this modification, since the support shaft portion 25 and the shaft portion 26 are formed integrally with the hook member 2 as compared with the above embodiment, the number of members can be reduced and the cost can be easily reduced.

  Note that the above embodiments do not limit the present invention. The hook apparatus of this invention should just be equipped with the technical element specified by Claim 1, and a detail can be variously changed as needed. For example, the support shaft portion is constituted by a dedicated shaft member. In addition, when upgrading, a mechanism for restricting the rotation of the hook member as exemplified in Patent Document 1 is adopted, or means for biasing the hook member in the direction of use as exemplified in Patent Document 2; A means for locking in the retracted state may be provided, and a means for braking the rotation of the hook member may be added.
