[0001]

[Industrial applications]

 The present invention relates to a desk clip for locking and connecting a top plate and a chassis on which the top plate is placed and which forms a desk together with the top plate.

[0002]

[Prior Art]

 As shown in FIG. 2, the desk clip is used when assembling the desk 10 by mounting the top plate 14 on a pair of chassis 12 forming left and right legs, and as shown in FIG. 13, the chassis 12 and the top plate are used. It is located between 14 and to connect both.

As shown in FIGS. 13 and 14, the desk clip 63 has a hanging piece 64 facing each other and a connecting piece 66 connecting the upper ends thereof. Both ends of the shaft 72 are fixed to the inner surface of the facing hanging piece 64. An upper end portion of a claw 70 is rotatably supported on the shaft 72, and an L-shaped hook 71 protruding outward is formed at a lower end portion of the claw 70. Further, the other end of the compression coil spring 74, one end of which is locked to the bridging piece 73 that is bridged between the hanging pieces 64, is fixed to the middle portion of the pawl 70, whereby the pawl 70 is fixed to the clip 63. Is urged outward.

Further, a taper portion 65 is formed at the lower end of the hanging piece 64 so as to become narrower toward the lower side. According to this taper portion 65, when the clip 63 is inserted into the insertion hole 80 formed in the upper surface of the plate material of the chassis 12, the outer peripheral surface of the clip 63 constitutes the insertion hole 80 and the lower part of the insertion hole 80 is formed. The insertion position of the clip 63 is regulated by being brought into contact with the wall portion 81 that shrinks corresponding to the taper portion 65. In this state, the tip of the taper portion 65 projects from the opening lower end 82 of the insertion hole 80.

Here, when the clip 63 is inserted into the insertion hole 80, as shown in FIG. 13, the hook 71 of the claw 70 is attached to the wall portion 81 of the insertion hole 80 as the clip 63 is inserted. Then, the claw 70 is pushed inward and rotates inward of the clip 63 against the biasing force of the compression coil spring 74. Then, when the clip 63 is completely inserted and the insertion position of the clip 63 is restricted, the hook 71 of the claw 70 comes out downward from the opening lower end 82 of the insertion hole 80 and the pressing is released, and the claw 70 is compressed. It is returned and rotated by the urging force of the coil spring 74, the hook 71 of the claw 70 is locked to the opening lower end 82 of the insertion hole 80, and the clip 63 is prevented from coming off.

On the other hand, an enlarged diameter disk 78 is provided on the upper surface of the connecting piece 66 via a neck portion 76. According to the expanded diameter disk 78, the expanded diameter disk 78 is inserted into the large diameter hole 54 formed in the lower surface of the plate of the top plate 14, and after the insertion, the neck portion 76 is connected to the large diameter hole 54 with a small diameter. When the slide plate is slid along the elongated hole 56 (see FIG. 3 for the large diameter hole 54 and the elongated hole 56), the top plate 14 is sandwiched between the expanded diameter disk 78 and the connection piece 66.

In this way, the clip 63 is locked to the chassis 12 and the top plate 14, and the chassis 12 and the top plate 14 are connected.

In order to remove the clip 63 from the insertion hole 80 of the chassis 12, the hook 71 of the claw 70 is pushed by using a driver so that the claw 70 resists the compression coil spring 74 and moves inward of the clip 11. Then, the hook 71 of the claw 70 and the lower end 82 of the opening of the insertion hole 80 are disengaged from each other.

[0009]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional desk clip 63, a shaft 72 for axially supporting the pawl 70 and a compression coil spring 74 for urging the pawl 70 are attached in order to attach the pawl 70 as a retaining member. Is needed.

Therefore, the number of component parts of the clip 63 is increased, the weight is increased, the manufacturing cost is increased, and each component part is made of metal, and rust may occur.

In consideration of the above facts, the present invention aims to provide a desk clip which can reduce the number of constituent parts, reduce weight and cost, and eventually realize a single part. .

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a head that is locked in a mounting hole formed in a top plate of a desk, and a top plate that is placed and is recessed in a chassis that forms a desk together with the top plate. In a desk clip that is configured to be inserted and locked in an insertion hole that has a storage wall in the direction, and the outer peripheral surface of the leg is cut in a U-shape in a desk clip that connects the top plate and the chassis. The elastic piece formed by cutting off the insertion direction side of the portion, and the locking portion provided at the tip of the elastic piece, and when the leg portion is inserted into the insertion hole, As the locking portion provided at the front end of the elastic piece is pressed by the edge portion of the storage wall to elastically deform the elastic piece inward of the leg, the locking portion moves inside the leg. When it moves toward the edge of the storage wall, the pressed state is released, the elastic piece elastically returns, and the locking portion is locked at the edge of the storage wall. Further, by pressing the elastic piece from the outside toward the inside of the leg portion, the engagement state between the edge portion of the storage wall and the engagement portion is released. It is a proposal for a clip.

Further, in the above-mentioned configuration, the elastic piece extends from the base of the elastic piece toward the inside of the leg, contacts the bottom surface formed at the tip of the leg, and extends toward the inside of the leg of the elastic piece. It is proposed to have a structure including an overhanging portion that controls the amount of deformation.

[0014]

[Action]

 In the desk clip configured as described above, the elastic piece is formed on the outer peripheral surface of the leg portion that is inserted into the insertion hole formed in the chassis. When the leg portion of this elastic piece is inserted into the insertion hole, the locking portion provided at the tip of the elastic piece is pressed against the end edge portion of the storage wall of the insertion hole, so that the elastic piece moves toward the leg portion. Elastically deforms inward. Next, when the leg is further pushed into the insertion hole and the locking portion separates from the edge of the storage wall, the elastic piece elastically returns and the locking portion is locked to the edge of the storage wall. .

Further, in order to release the locked state between the locking portion and the edge portion of the storage wall, the elastic piece is pushed inward of the leg portion by a driver or the like, and at the same time, the leg portion is pushed through the insertion hole. It is enough to remove it, and the simple operation is enough.

As described above, since the elastic piece is formed integrally with the clip, the number of constituent parts can be reduced, the weight can be reduced, and the cost can be reduced.

Further, the inward deformation of the leg portion of the elastic piece is such that the bottom surface provided at the tip of the leg portion is stretched inward from the base portion which is the center of rotation of the elastic piece. The amount of deformation is limited by the contact of the protrusion. This prevents the elastic piece from being deformed more than necessary, and avoids weakening the elastic piece.

【Example】

 A first embodiment of a desk clip according to the present invention will be described in detail with reference to FIGS.

FIG. 2 shows a desk 10 to which a desk clip 11 is applied. As shown in FIG. 3, the desk 10 includes a pair of left and right chassis 12 which are U-shaped legs with an open front, and a top plate 14 straddles the chassis 12. It is placed and connected by a clip 11 (see FIG. 3). In the figure, 13 is a cover panel of the desk 10.

The clip 11 is composed of a leg portion 16 corresponding to the chassis 12 and a head portion 18 corresponding to the top plate 14.

The leg portion 16 corresponding to the chassis 12 is formed in a box shape and, as shown in FIGS. 4 to 8, when viewed from the front side of the desk 10 (in the direction of arrow A in FIGS. 1 to 3). (Seeing), the back surface is open and the other five surfaces are closed by the front wall 24, the top wall 26, the bottom wall 28, the left wall 30 and the right wall 32, as shown in FIG. The chassis 12 is designed to be inserted into an insertion hole 34 formed in the upper surface of the upper wall of the chassis 12.

The left side wall 30 and the right side wall 32 of the leg portion 16 have one side edge of the upper end portion extending outward from the front wall 24 and the other side edge so that the upper end portion is the lower end portion. The taper portion 25 is formed in the middle portion and has a narrow width. Further, between the left side wall 30 and the right side wall 32 of the leg portion 16, a reinforcing middle wall 40 is formed so as to span the central portion in the vertical direction, and the left side wall 30 and the right side wall 32 are formed. A reinforcing rib 44 is formed so as to project from the upper end portion to the intermediate portion at the widthwise central portion on the outer surface of the.

Here, the insertion hole 34 of the chassis 12 has a storage wall 35 formed in a tapered shape corresponding to the shape of the tapered portion 25 of the leg portion 16, and the lower end of the leg portion 16 is provided. In a state in which the portion is projected downward from the end edge portion 36 of the storage wall 35, the tapered portion 25 of the leg portion 16 is brought into contact with the storage wall 35, and movement of the leg portion 16 in the insertion direction is restrained, and at the same time, it is inserted. Rotation around the axis of the entry direction is restricted. A rib groove 45 is formed in the insertion hole 34 so as to correspond to the reinforcing rib 44, as shown in FIG.

An elastic piece 22 is formed at the lower end of the front wall 24 of the leg portion 16. The elastic piece 22 is formed to be thinner than the front wall 24 of the leg 16 and has a rectangular shape, and the peripheral edge of the elastic piece 22 is U-shaped except for the lower end continuous with the front wall 24 of the leg 16. It is cut (the lower end of the elastic piece 22 is left uncut). As a result, the elastic piece 22 is elastically deformable so as to rotate around the lower end of the elastic piece 22 as an axis. Further, a portal-shaped reinforcing rib 43 is provided on the outer surface of the elastic piece 22 except the lower end of the peripheral edge thereof. The reinforcing rib 43 is inclined so that the protruding length thereof becomes longer as it goes toward the upper end portion of the elastic piece 22, and the upper end portion thereof serves as the locking portion 42.

According to this, as the leg portion 16 is inserted into the insertion hole 34, the locking portion 42 of the elastic piece 22 is pressed against the end edge portion 36 of the storage wall 35 of the insertion hole 34, so that FIG. As shown in FIG. 5, the leg 16 is moved inward in the direction of arrow B. When the elastic piece 22 is further inserted, the locking portion 42 of the elastic piece 22 leaves the end edge portion 36 of the storage wall 35 of the insertion hole 34, and the elastic piece 22 elastically returns to the chassis 12 as shown in FIG. Outside the insertion hole 34, the locking portion 42 of the elastic piece 22 is locked to the end edge portion 36 of the storage wall 25 of the insertion hole 34.

On the other hand, the head portion 18 corresponding to the top plate 14 is provided on the upper surface of the upper surface wall 26 of the leg portion 16, is protruded upward through the neck portion 52, and has a diameter-expanded portion 48 in a part thereof. It is composed of a disk 50.

As shown in FIG. 3, the enlarged diameter disc 50 is adapted to be inserted into a large diameter hole 54 formed in the lower wall of the double wall of the top plate 14, and the large diameter hole 54 The neck 52 is slid relative to and positioned in a small-diameter long hole 56 that is formed continuously with the large-diameter hole 54 and constitutes a mounting hole. The lower wall of the top plate 14 is sandwiched between the disc 50 and the upper wall 26 of the leg 16.

The clip 11 configured as described above is obtained by integrally molding with a mold using a resin molding material.

Next, the operation of this embodiment will be described. In order to insert and lock the leg portion 16 of the clip 11 in the insertion hole 34 of the chassis 12, as shown in FIG. 10, when the leg portion 16 is inserted into the engagement hole 34 of the chassis 12, the leg portion 16 As the lower end portion penetrates the insertion hole 34, the locking portion 42 of the elastic piece 22 is pressed by the end edge portion 36 of the storage wall 35 of the insertion hole 34 to rotate the elastic piece 22 inward of the leg portion 16. Then, the locking portion 42 of the elastic piece 22 moves inward of the leg portion 16. Then, when the locking portion 42 of the elastic piece 22 comes out downward from the end edge portion 36 of the storage wall 35 of the insertion hole 34 and separates, the taper portion 25 of the leg portion 16 contacts the storage wall 35 of the insertion hole 34. As a result, the insertion position of the engagement body 20 is restricted. At the same time, the locking portion 42 of the elastic piece 22 is released and deformed so that the pressing by the end edge portion 36 of the storage wall 35 is released, and the elastic piece 22 is returned to the original shape so that the locking piece 22 is locked. The portion 42 is located outside the insertion hole 34 and is locked to the end edge portion 36 of the storage wall 35. This locking prevents the leg portion 16 from coming off.

On the other hand, as shown in FIG. 9, in order to engage the head portion 18 corresponding to the top plate 14 with the mounting hole of the top plate 14, after inserting the enlarged diameter disk 50 into the large diameter hole 54, The neck 52 is relatively slid along the long hole 56. As a result, the head portion 18 is locked in the elongated hole 56, and the top plate 14 and the chassis 12 are connected.

When removing the leg portion 16 of the clip 11 from the insertion hole 34, the engagement state between the engagement portion 42 of the elastic piece 22 and the end edge portion 36 of the storage wall 35 of the insertion hole 34 is released. For example, the central portion of the elastic piece 22 surrounded by the reinforcing ribs 43 is pressed from the outside (in the direction shown by the arrow B in FIG. 9) by, for example, the tip of the driver 52, and the elastic piece 22 of the leg portion 16 is pressed. It is sufficient that the legs 16 are elastically deformed inward and the legs 16 are pulled out in this state, and extremely simple operation is sufficient.

Further, in the head portion 18 corresponding to the top plate 14, in order to remove the expanded diameter disk 50 from the mounting hole of the top plate 14, the neck portion 52 is directed from the long hole 56 to the large diameter hole 54. , It may be slid in the direction opposite to the arrow C in FIG.

Here, the locking and releasing of the locking portion 42 of the elastic piece 22 with respect to the end edge portion 36 of the storage wall 35 of the insertion hole 34 is performed by the elastic piece 22 integrally formed on the leg portion 16. Since the legs 16 are integrated by elastic deformation, the number of components is reduced, and the weight and cost can be reduced.

Further, by integrally forming the leg portion 16 with the head portion 18 corresponding to the top plate 14, a single part of the clip is achieved, and in particular, the leg portion 16 together with the head portion 18 is made into a resin. By integrally molding the clip 11, the clip 11 can be easily made into a single part and there is no risk of rust.

Next, a second embodiment will be described. In the desk clip 48 in this embodiment, as shown in FIGS. 11 and 12, the elastic piece 22 is provided with the overhanging portion 46 inwardly of the leg portion 50. The overhanging portion 46 is formed on the entire inner surface from the tip end portion to the base portion of the elastic piece 22 so as to become thicker as it goes downward, and between the lower surface of the overhanging portion 46 and the bottom wall 28 of the leg portion 16. Has a gap formed.

According to this structure, when the leg portion 50 of the clip 48 is removed, the elastic piece 22 is released from the engagement state with the end edge portion 36 of the storage wall 35 of the insertion hole 34, as shown in FIG. In addition, when the elastic piece 22 is pressed by the tip of the driver 52 and the amount of deformation of the elastic piece 22 that is rotationally deformed in the direction indicated by the arrow B reaches a predetermined amount, the lower surface of the overhanging portion 46 causes the leg portion 16 to move downward. It abuts the upper surface of the bottom wall 28 and limits further deformation.

Therefore, after the deformation necessary for releasing the locking state of the locking piece 22 with respect to the end edge portion 36 of the storage wall 35 of the insertion hole 34 is obtained, excessive deformation is restricted. Thus, weakening due to deformation of the locking piece 22 is avoided.

Further, the overhanging portion 46 also functions as a reinforcing rib for the elastic piece 22. The overhanging portion 46 does not have to be formed on the entire inner surface of the elastic piece 22 as long as it extends over at least the inside of the leg portion 50 from the base of the elastic piece 22.

Further, the clip 48 including the projecting portion 46 can be integrally molded of resin.

The other configurations and effects are similar to those of the first embodiment. Although the respective embodiments have been described above, the present invention is not limited to the above-mentioned embodiments and various modifications can be made.
