Description

  The present invention relates to a structure suitably used when a second member is attached to a first member so as to be rotatable around two orthogonal axes, and a hanging device using the structure.

  For example, an accessory hook called a magnet hook is known as this type of hanging tool. This accessory hook is roughly divided into a fixed type in which a hook body for hanging an article is simply fixed on a pedestal provided with a magnet on the back surface, and the hook body is rotatably attached around an axis protruding from the surface of the pedestal 1 It is classified into a shaft rotation type and a biaxial rotation type in which a hook body is rotatably mounted around an axis protruding from the surface of the pedestal and an axis orthogonal to the axis.

  Among these, the one-axis rotation type and the two-axis rotation type have the hook body from the surface of the pedestal regardless of the mounting direction of the pedestal when the pedestal is mounted on a vertical metal surface such as a cabinet door. Since it can be rotated around the projecting axis to take a drooping posture, there is the convenience that an appropriate use state can be ensured even if it is attached unreasonably. Furthermore, in the case of the two-axis rotation type, when the pedestal is attached to a horizontal metal surface such as the lower surface of the shelf board, the hook body is rotated by 90 degrees around the axis orthogonal to the axis and suspended from the surface of the pedestal Therefore, the degree of freedom of the mounting direction can be further improved.

As such a biaxial rotation type hanging tool, the one shown in Patent Document 1 is known.
Japanese Utility Model Publication No. 57-46864

  However, in Patent Document 1, a hollow body-like insertion portion provided in a rotating member is inserted into a hole provided in a pedestal, and a locking portion provided by bulging at the tip of the insertion portion is vertically divided. By inserting the pin into the hole from the back in this state, it is inserted into the hole provided in the pedestal while compressing the insertion part, and the locking part is expanded at the insertion end. Thus, the rotary member is press-fitted into the hollow portion to prevent the rotating member from falling off the pedestal. An insertion recess is opened in the axial direction perpendicular to the axis of the rotating member, and the proximal end of the hook body is pivotally attached.

  In this way, the rotating member is first rotatably attached to the pedestal in a state where it cannot fall off, and then the hook body is pivotally attached to the rotating member, so the number of parts is large and the structure is complicated, There is a problem that work is troublesome because there are many processing and assembly processes.

As other structures, a structure in which a claw or a rib is provided so that it cannot be removed once the insertion portion of the rotating member is fitted into the hole portion, or a pin is provided on the rotating member side to provide a hole. There is a structure that can be caulked at the passing position of the part, but in each case, the rotating member is attached to the pedestal so that it can not be dropped, and then the hook body is pivotally attached to the rotating member. The structure is the same as that of Document 1 and has the same problems.

  The present invention has been made paying attention to such a problem, and is not limited to the relationship between the pedestal and the hook body. Generally, the second member with respect to the first member is arranged around two orthogonal axes by a simple structure. It is an object of the present invention to provide a novel and useful structure that can be rotatably mounted and a hanging device using the structure.

In order to achieve this object, the present invention takes the following measures.

That is, the structure of the present invention is a structure in which the second member is attached to the first member so as to be rotatable around two orthogonal axes, and the rotating member is interposed between the first member and the second member. This rotating member can be rotated around the first axis by being externally fitted to a support shaft provided on the first member, and an insertion recess is formed in the second axis direction perpendicular to the first axis. The second member is opened, and can be rotated around the second axis by pivotally mounting the base end to the insertion recess of the rotating member, and the base end is pivotally supported by the first member when pivotally mounted. It is characterized in that means is provided for engaging the part without disturbing the rotation of the rotating member and prohibiting the removal of the rotating member from the first member.

In such a configuration, the second member can rotate around the first axis of the first member together with the rotating member, and can rotate around the second axis relative to the rotating member. As a result, the first member can be rotated around two orthogonal axes. In addition, since the structure in which the base end of the second member is pivotally attached to the rotating member also serves to inhibit the rotating member from falling off the first member without preventing the rotating member from rotating, the first member is first rotated. Compared to the case where the structure is such that the member can be rotated in a state where it cannot fall off and then the second member is attached to the rotating member, the number of parts can be reduced and the structure can be simplified. Therefore, the work efficiency can be effectively improved.

As a concrete embodiment, the means for prohibiting the above-mentioned removal is provided in a pair with the base end of the second member together with the insertion recess. The thing which enters into the circumferential groove provided in the outer periphery of the spindle part of a member, and is made to engage is mentioned.

As a particularly preferable structure, at least the base end of the second member is made of an elastically deformable wire, and after a pair of opposing base ends are elastically deformed away from each other, they are pivotally attached to the insertion recess of the rotating member. It is preferable that the base end be configured not to be disengaged from the circumferential groove and the insertion recess of the rotating member unless it is engaged with the circumferential groove of the support shaft and elastically deformed again.

In order to improve the appearance and the operation, it is preferable that the rotating member has a bottomed cylindrical shape including substantially the entire support shaft portion including the circumferential groove.

As a hanging tool using such a structure, a pedestal, which is a first member having a support shaft portion projecting on the front surface and an attachment portion formed on the back surface, and a detachable outer fit on the support shaft portion of the pedestal A rotating member having an insertion recess opened in a direction orthogonal to the axis of the support shaft, and a hook body as a second member pivotally attached to the insertion recess of the rotating member. The base end may be engaged with the support shaft portion of the pedestal without pivoting the rotation of the rotating member at the time of pivoting to prevent the rotating member from being detached from the first member.

With the configuration described above, the present invention has a reduced number of parts, a simple structure, and fewer processing and assembly processes. Therefore, the parts cost and manufacturing cost when manufacturing a hanging tool are greatly increased compared to the conventional one. It becomes possible to reduce.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1-6 has shown the magnet hook which is a hanging tool using the structure of this invention.

This magnet hook is obtained by attaching a hook body 3 as a second member for hanging small items to a base 1 as a first member attached to a wall or the like via a rotating member 2.

The pedestal 1 is formed by projecting in the normal direction (first axial center m direction) from the center of the surface of a flat bottomed cylindrical main body 11 made of a resin material, and integrally forming a support shaft 12. The flat cylindrical magnet 4 made of a material such as neodymium is accommodated in the main body 11 so that it cannot be peeled off, and the back surface 4a of the magnet 4 forms an attachment portion. The support shaft portion 12 has a circumferential groove 12a provided on the outer periphery of the central portion in the axial direction of the cylindrical body, and the central longitudinal section has an H shape.

The rotating member 2 has a bottomed cylindrical shape made of a resin material, and is detachably fitted to the support shaft portion 12 of the base 1 so as to include substantially the entire support shaft portion 12 including the circumferential groove 12a. It has an inner space 2a. The rotating member 2 rotates relatively smoothly with respect to the support shaft portion 12. A through hole 21a, which is an insertion recess that opens in the direction passing through the first axis m and perpendicular to the first axis m (in the direction of the second axis n), is located at a position opposite to the first axis m of the peripheral wall 21. Provided.

The hook body 3 is capable of plastically deforming an elastically deformable linear body, is connected to a curved portion 31a described later from a pair of opposed base ends 31, and further, a hook region 33 reaching the distal end portion 32 is obliquely U-shaped in a side view. As shown in FIG. 3, various small articles Z can be hooked and hung from the tip 32 toward the bottom of the hook region 33. The base end 31 of the hook body 3 is coaxially opposed with a predetermined distance d (see FIG. 4).

And after elastically deforming between the base ends 31 and 31 of the hook body 3 in the direction which mutually leaves | separates temporarily as shown by the arrow X in FIG. 4, it is restored | restored by inserting in the said through-hole 21a, restoring | restoring Thus, the insertion end of the base end 31 is inserted into the circumferential groove 12a of the support shaft portion 12 of the base 1 so as to be engaged therewith. In this state, the opposing direction of the base end 31 of the hook body 3 coincides with the second axis n, and the hook body 3 is pivotally mounted around the second axis n. The predetermined distance d described above substantially corresponds to the diameter R of the center portion 12b located inside the circumferential groove 12a of the support shaft portion 12. The base end 31 is prevented from being detached from the circumferential groove 12a and the through hole 21a of the rotating member 2 unless the base end 31 is further elastically deformed in the direction of expanding the base end 31 between the hook body 3.

The hanging tool of the present embodiment having such a configuration can rotate the hook body 3 around the first axis m of the pedestal 1 as shown by an arrow in FIG. Further, the hook body 3 can be rotated around the second axis n as shown by the arrow in FIG. 7B with respect to the rotating member 2, so that the hook body 3 is orthogonal to the base 1 as a result. It can be rotated about two axes (m, n).

Therefore, when the base 1 of the hanging device is attached to a vertical metal surface such as a cabinet door, the hook body 3 rotates about the axis m of the base 1 regardless of the mounting direction of the base 1. By doing so, it is possible to take a vertical drooping posture, and it is possible to ensure an appropriate use state even if it is handled in a random manner. Further, since the hook body 3 can rotate around the axis n orthogonal to the axis m, for example, when the pedestal 1 is attached to a horizontal metal surface such as the lower surface of the shelf board, FIG. As shown by the imaginary line in b), if the hook body 3 is rotated by approximately 90 °, the hook region 33 can be suspended substantially vertically from the surface of the pedestal 1, and the degree of freedom of the mounting orientation can be further improved. It becomes.

Moreover, the structure in which the base end 31 of the hook body 3 as the second member is pivotally attached to the rotating member 2 prevents the rotating member 2 from dropping from the base 1 as the second member at the same time without disturbing the rotation of the rotating member 2. Therefore, the number of parts can be reduced as compared with the conventional structure in which the rotating member 2 is pivotally attached to the base 1 and the hook body 3 is attached to the rotating member 2 separately. In addition, since the number of processing and assembly processes is small, work efficiency can be effectively improved. Therefore, the cost of the product can be effectively reduced as compared with the conventional case.

Specifically, the base end 31 of the hook body 3 which is the second member is provided in a pair with the through hole 21a which is the insertion recess, and the base end 31 is passed through the through hole 21a when pivotally attached to the first member. The structure of the three members 1, 2 and 3 is very simple because it only needs to be engaged with a position in the circumferential groove 12a provided on the outer periphery of the support shaft portion 12 of the pedestal 1. Attaching can be completed easily in one operation.

In particular, the hook member 3 as the second member is formed of a linear body that can be elastically deformed, and after the pair of opposed base ends 31 are elastically deformed in directions away from each other, the hook member 3 is pivotally attached to the through hole 21a of the rotating member 2. Since the base end 31 cannot be detached from the circumferential groove 12a and the through hole 21a of the rotating member 2 unless it is engaged with the circumferential groove 12a of the support shaft portion 12 and elastically deformed again, the rotating member 2 or It is possible to effectively prevent the hook body 3 from accidentally falling off.

In particular, a curved portion 31 a that changes the direction of the linear body by 90 ° or more is provided at the boundary portion between the base end 31 of the hook body 3 and the hook region 33, and the base ends 31, 31 are opened by a load applied to the hook region 33. Since the structure is difficult, an appropriate use state can be effectively maintained in this respect as well.

Further, since the rotating member 2 has a bottomed cylindrical shape including substantially the entire support shaft portion 12 including the circumferential groove 12a, once the rotating member 2 is put on the base 1 and the hook body 3 is attached, the base 1. The rotating member 2 and the hook body 3 conceal the internal structure and are assembled together without gaps, exhibiting a good appearance, and at the same time, having an effect that the operation is also good without rattling. In particular, since the base end 31 of the hook body 3 is in close contact with or close to the center part 12b of the support shaft part 12, it is possible to prevent the hook body 3 from rattling in the axis n direction and to obtain a good feeling of use. Can do.

As described above, when the present invention is used as a hanging tool, the effect is excellent, but the structure of the present invention has a lower degree of freedom of rotation around two orthogonal axes with respect to other members. It can be widely applied to various uses in which other members are to be attached.

In addition, the specific configuration of each part including the shape of the hook body and the like is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
