TECHNICAL FIELD OF THE INVENTION
The present invention relates to a member mounting structure in which a member can be hooked on a required hook portion using an elastic claw.
[0002]
[Prior art]
2. Description of the Related Art A mounting structure in which an elastic claw for hooking is provided on a part of a member and the member is mounted by hooking the elastic claw on a hook portion set at a mounting position has been generally known. As one example, a structure in which a wiring duct is vertically attached to the inner surface of a panel constituting a desk can be cited.
[0003]
Such a wiring duct is generally formed in a channel shape, and is arranged by striking a pair of side walls against the front surface of the panel such that the duct space faces the panel side, and an upward hook-shaped elastic claw is provided on the upper end side of the side wall. At the same time, a downward hook-shaped elastic claw is provided at the lower end side. Then, these elastic claws are elastically engaged with a bent portion that opens downward on the upper edge of the panel and a bent portion that opens upward on the lower edge side of the panel, so that the wiring duct is attached to the panel. . At this time, the elastic claw is formed of a single leg having a base end supported at an appropriate position on the side wall and having a free end at the tip, and a hook-shaped hook portion is formed at the tip end of the leg. It is customary.
[0004]
[Problems to be solved by the invention]
By the way, in such a conventional mounting structure, when it is necessary to increase the strength of the elastic claw, there is no other way than to make the legs thicker. However, conventional elastic claws are mainly composed of a single leg in the form of a plate, so that there is a limit in improving strength and delicate adjustment of elastic force. In some cases, the elastic claws may break. Further, in order to change the thickness of the legs, a large change in the mold is required.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides an elastic claw having a block shape without impairing its elastic deformation function, thereby enabling effective improvement of strength and a delicate elastic force. It is configured such that any adjustment can be performed by parameters other than the thickness of the legs forming the elastic claws.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
For this purpose, the member mounting structure of the present invention is configured such that an elastic claw for hooking is provided on a part of the member, and the member is mounted by hooking the elastic claw on a hook portion set at the mounting location. A pair of legs capable of elastically deforming the elastic claws in the facing direction by projecting the elastic claws on the base end side of the member and projecting the distal end side in a face- to- face state, and a connecting portion connecting the front end portions of both legs. A hook portion is formed on a part of the leg or the connecting portion so as to engage with the latch portion, and the elastic claw is integrally formed with the member .
[0007]
According to such a mounting structure, the strength is doubled due to the pair of legs, and the resistance caused by the difference in the amount of bending between the legs when the entire leg, including the connecting portion, attempts to bend during elastic deformation. It can be expected that the strength will be improved. In particular, even if the present invention is repeatedly used for a long period of time, since the load applied during elastic deformation can be dispersed and supported by each elastic claw, damage and breakage due to fatigue can be effectively prevented for a long period of time. .
Further, since the elastic claws are integrally formed together with the member, the function of the elastic claws can be easily performed and appropriate.
[0008]
In order that the fine adjustment of the elastic force can be performed without relying only on the thickness of the leg, the member has a portion along the leg of the elastic claw and a portion extending on the same plane from the portion. It is preferable to have a side wall, and to connect between the leg and the side wall over a certain area on the base end side.
As a specific embodiment, the member is a channel-shaped member having a bottom wall and a pair of side walls, and the base end sides of the elastic claws paired with the bottom wall are positioned between the side walls. In addition to supporting the elastic nails, a leg and a corresponding side wall of each elastic claw are connected to each other over a certain area on the base end side.
[0009]
In order to perform the function of the elastic claw easily and properly, it is desirable that the elastic claw is integrally formed with the member together with the resin.
As a preferable application example of the present invention, a member in which a member is a wiring duct and a mounting portion is a panel forming a desk is cited.
As the existing structure, the panel has a bent portion having an opening groove that opens upward at a lower edge of the panel, and an opening that opens upward along the width direction at a position above the bent portion of the panel. A cord receiving attachment portion having a groove is formed, and as an embodiment of the present invention suitable for arranging a wiring duct in a vertical direction across the cord receiving attaching portion and the bent portion, a part of a member is provided. An elastic claw for hooking is provided, and the member is attached by hooking the elastic claw on a hook portion set at a mounting position, and the elastic claw is supported at the base end side by the member. A pair of elastically deformable legs having protruding distal ends, and a connecting portion for connecting between the distal ends of both legs, and a hook portion that engages with a latch portion on a part of the leg or the connecting portion. The member is a wiring duct, the mounting portion is a panel forming a desk, and a bent portion having an opening groove that opens upward at a lower edge of the panel is formed, and a bent portion of the panel is formed. Also, a cord receiving attachment portion having an opening groove that opens upward along the width direction is formed at an upper position, and a wiring duct is vertically arranged over the cord receiving attaching portion and the bent portion to form a cord receiving portion.

[0010]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The member mounting structure of this embodiment is used when a wiring duct 3 as a member of the present invention is mounted on a panel 2 constituting a desk 1 shown in FIG.
The desk 1 has the top plate 12 supported between the upper ends of the left and right legs 11 and the panel 2 is provided at a position where the non-use end side of the lower limb space 13 is blindfolded. A bent portion 21 that is disposed between the inner surfaces of the body 11 and has an opening groove 21a that opens upward at the lower edge is formed, and a position above the bent portion 21 also serves to reinforce the face plate portion of the panel 2, A cord receiving attachment portion 22 having an opening groove 22a that opens upward in the width direction is formed. The cord receiver mounting portion 22 can hold the cord receiver 23 at an appropriate position in the width direction, and can hold the cord receiver 23 by winding the cords around the cord receiver 23 or the like.
[0011]
A pair of hooking elastic claws 30 is provided on the upper end side of the wiring duct 3, and these hooks 30 are hooked in the opening grooves 22 a of the cord receiving attachment portion 22 which is a hooking portion of the present invention. In this way, the wiring duct 3 is attached, and the wiring duct 3 can be guided on the top plate while concealing the wiring rising from the floor.
[0012]
As shown in FIGS. 3 to 5, the wiring duct 3 is a channel having a bottom wall 31 and a pair of side walls 32, and has a longitudinal dimension between the cord receiving mounting portion 22 and the bent portion 21. The side wall 32 has a concave portion 32a that opens downward, and a concave portion 32b that opens rearward near the rear edge near the upper end of the side wall 32.
[0013]
Each of the elastic claws 30 is located between the side walls 32 of the wiring duct 3 and at a position adjacent to the inner side of each side wall 32, and has a pair of plate-like legs 30a, 30b, and tips of the legs 30a, 30b. And a connecting portion 30c for connecting the portions. The legs 30a and 30b have their base ends supported by the bottom wall 31 of the wiring duct 3 and their front ends projecting in parallel along the side wall 32 of the wiring duct 3 in a face-to-face state. The end portions 30a and 30b are smoothly connected with substantially the same plate thickness. Between the side wall 32 and each of the legs 30a and 30b, the mold is devised with a simple design so that the fixed region X (see FIG. 4) on the base end side is connected to each other by a resin material after molding. Alternatively, a connection portion X1 is formed in the region X by making an appropriate cut after molding. A hook portion 30d that engages with the cord receiving attachment portion 22 is formed on the lower surface of the leg 30b that is located on the lower side in the attached state. The hook portion 30d has a downward hook shape, that is, a downwardly projecting mountain shape so that the hook portion 30d can be hooked in the opening groove 22a of the cord receiving attachment portion 22.
[0014]
In order to attach the wiring duct 3 having the above-described configuration, first, in a rearwardly inclined position shown by imaginary lines in FIG. Fit from. Then, the wiring duct 3 is rotated in the upright direction with the fitted portion as a fulcrum. At this time, the hooks 30d of the elastic claws 30 provided on the upper end side of the wiring duct 3 gradually move elastically upward when the legs 30a and 30b cross over the upper surface of the cord receiving and mounting portion 22, and at positions where the legs 30a and 30b cross over. The legs 30a and 30b are restored to the original state, and the hook portion 30d can elastically engage with the opening groove 21a of the cord receiving and attaching portion 21. In this state, the wiring duct 3 can be slid along the width direction while maintaining the engagement state, and if the operation reverse to that at the time of mounting is performed, the wiring duct 3 can be easily removed from the panel 2. Can be removed.
[0015]
As described above, in the member mounting structure of the present embodiment, the elastic claws 30 are supported by the wiring duct 3 on the base end side and protrude in parallel with the distal end side facing each other (in the direction of the arrow in FIG. 5). ) Has a pair of elastically deformable legs 30a, 30b and a connecting portion 30c for connecting the distal ends of both legs 30a, 30b. A hook portion 30d that engages with the attachment portion 22 is formed. The hook portion 30d is hooked on the cord receiving attachment portion 22, so that the wiring duct 3 can be attached to the panel 2. .
[0016]
For this reason, the strength is doubled due to the pair of the legs 30a and 30b, and the entire structure including the connecting portion 30c tends to bend during elastic deformation due to the structure in which the legs 30a and 30b protrude in a facing state. The difference in the amount of deflection between the legs 30a and 30b at this time can be expected to improve the strength due to the resistance, and a more reliable mounting state of the members can be realized as compared with the conventional mounting structure. In particular, even if the present embodiment is repeatedly used for a long period of time, the load applied during the elastic deformation can be dispersed and supported by the respective elastic claws 30. And breakage can be effectively prevented.
[0017]
Further, the wiring duct 3 has side walls 32 along the legs 30a, 30b of the elastic claw 30, and the side walls 32 and the respective legs 30a, 30b are connected over a certain region X on the base end side. If the region X is made longer, the deformation of the elastic claw 30 is more restricted, and if the region X is made shorter, the deformation becomes easier. This can be done not only by the thickness but also by the width of the connection area, and the degree of freedom in setting the elastic force can be greatly improved as compared with the related art.
[0018]
In particular, in the present embodiment, the wiring duct 3 is formed in a channel shape having a bottom wall 31 and a pair of side walls 32, and the elastic claws 30 forming a pair with the bottom wall 31 are positioned between the side walls 32, 32. Are supported, and the legs 30a and 30b of each elastic claw 30 and the corresponding side wall 32 are connected to each other over a fixed area X on the base end side. It can be mounted evenly on the panel 2 to ensure the mounting state.
[0019]
Further, in this embodiment, since the elastic claws 30 are integrally formed with the wiring duct 3 by resin, the manufacturing can be simplified and a required elastic deformation function can be easily provided.
As described above, this embodiment can be extremely useful when attaching the wiring duct 3 to the panel 2 of the desk 1.
[0020]
In particular, the panel 2 of this embodiment has a bent portion 21 that opens upward at the lower edge thereof, and a cord receiving mounting portion that opens upward along the width direction at a position above the bent portion 21 of the panel 2. In order to arrange the wiring duct 3 in the vertical direction across the cord receiving attachment portion 22 and the bent portion 21, the wiring duct 3 is used as a hook portion for the cord receiving attachment portion 22. Since the elastic claw 30 having the hook portion 30d having a downward hook shape is provided at the corresponding position, the wiring duct 3 can be effectively attached without changing the existing desk structure.
[0021]
In addition, an elastic claw having a hook portion having a downward hook shape may be provided at a position corresponding to the wiring duct, with the bent portion on the lower edge side of the panel as a hook portion.
In this way, even if the upper or lower elastic claw is inserted first, the other elastic claw can be engaged with the corresponding latching portion with the fulcrum as a fulcrum, thereby effectively improving the degree of freedom in mounting. Can be done. Of course, in such a configuration, the upper and lower elastic claws can be engaged with the corresponding latch portions by simply moving the wiring duct horizontally, so that the degree of freedom of attachment is further increased. In addition, the specific configuration of each part is not limited to the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention. In addition, the present invention can be applied to various things such as a movable partition wall other than the desk.
[0022]
【The invention's effect】

That is, member mounting structure of the present invention, upon mounting the member hooked to the retaining portion over the elastic claw to the required attachment points, the elastic claw, and a distal end side is supported proximally member is projected in a face-to-face state A pair of legs that can be elastically deformed in the opposite direction and a connecting portion that connects between the tip portions of both legs, and a hook portion that engages with the latch portion is formed on a part of the leg or the connecting portion. And the elastic claw is integrally formed with the member .
[0023]
For this reason, in addition to the doubling of the strength due to the paired legs, an improvement in the strength due to the difference in the amount of deflection between the legs serving as resistance can also be expected, and even if used repeatedly over a long period of time. In addition, it is possible to prevent damage and breakage due to fatigue, and to provide a mounting structure that is more excellent in strength and durability than before.
Furthermore, since the elastic claw is integrally formed with the member, the number of parts and man-hours can be reduced, and the connection between the base end of the elastic claw and the member is ensured to realize a mounting structure that is hard to break. it can.
The member may have a side wall having a portion along the leg of the elastic claw and a portion extending on the same plane from the portion, and the leg and the side wall may be connected over a certain area. The larger the area, the more the deformation of the elastic claw is limited, so the fine adjustment of the strength and elastic force of the elastic claw through the dimension setting of the connection area, coupled with the setting of the leg thickness It can be performed effectively without accompanying.
[0024]
When the member is in the form of a channel, a pair of elastic claws are projected from the bottom wall positioned between the side walls of the member, so that the legs of each elastic claw and the side wall located adjacent thereto are connected to each other. In this case, the members can be uniformly engaged with the latching portion in the left and right directions, so that the mounting state can be made stable and reliable.
If the elastic claws are integrally formed of resin together with the wiring duct, it can be manufactured simply and a required elastic deformation function can be easily provided.
[0025]
