BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a connecting device for removably connecting two members of a desk and furniture such as a side cabinet to each other.

[0002]

2. Description of the Related Art For example, Japanese Utility Model Publication No. 36-18605 discloses an apparatus for interconnecting two plate-like members.
The two plates are composed of a locking rod formed by forming a plurality of annular locking ridges at an end portion of a shaft body with a large diameter head at appropriate intervals in the axial direction, and an elastic locking plate having a radial groove. A configuration is disclosed in which a stop rod is inserted into a through hole formed in a member, and a radiation groove in the elastic locking plate is locked to a locking ridge at a tip end portion of the stop rod protruding from the other member. .

[0003]

According to this configuration, the fastening device and the stop rod must be held by both hands at the time of connecting work, which is troublesome for connecting work. Further, since the fastener is engaged with the stop rod in a state where the fastener is exposed on the outer surface of the other member, when the thickness of the other member is large, the length of the stop rod must be increased. There is a disadvantage that it does not. In other words, there is a drawback that the fastener cannot be located in the middle of the thickness of the member, and it is difficult to attach the fastener to a so-called blind hole.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting device which can eliminate the drawbacks of the prior art and can be easily connected.

[0005]

In order to achieve the above object, a connecting device according to the present invention is a device for connecting a first member and a second member of furniture or the like, wherein a base end of a shaft portion is a first member. A stop rod which is irremovably attached to a member and has a locking projection formed at a tip end of a shaft protruding from the first member, and faces a locking rod in which the locking projection of the locking rod is locked. A fastening device made of an elastic plate having a pair of inward locking claws, and a receiving body having a storage portion for detachably storing the fastening device,
The second member has a mounting hole through which a receiving body storing the fastener can be inserted from a side, and an end surface of the second member has a receiving portion for receiving the receiving body inserted into the mounting hole. A communication hole through which the locking projection of the locking rod can enter is inserted between a pair of locking claws of the fastener, and the receiving body is opened on the side of the second member of the mounting hole. A cap for covering the portion is provided integrally.

[0006]

According to this construction, if the fastener is previously stored in the receiving portion of the receiving body and this receiving body is inserted in advance into the mounting hole formed on the side surface of the second member,
This fastener does not fall off, and the insertion work is extremely simple as compared with inserting only the fastener into the mounting hole.
Further, by the insertion, the portion of the mounting hole that opens to the side of the second member can be covered with the cap of the receiving body, so that the fastener part can be hidden from the outside of the second member, and the appearance can be reduced. There is an effect that it can be improved.

[0007] Then, the locking projection of the distal end of the stop rod protruding from the first member is inserted from the communication hole of the second member toward the mounting hole, and the locking projection of the stop rod is provided in the fastener. When the pair of locking claws are pressed, the pair of locking claws are temporarily separated from each other by the elastic deformation of the elastic plate body of the fastener, and then the pair of locking claws are engaged with the small diameter side of the locking projection. Can be stopped. Therefore, by using the connecting device of the present invention, the two members can be connected extremely easily, and the usability can be remarkably improved and the appearance of the connecting portion is also improved.

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view of a desk, and FIG. 2 is a perspective view of a receiving body and a fastener in the connecting device. The desk 1 has legs 3, 3 attached to the lower surface on both left and right sides of the top plate 2 by a connecting device described later. The side cabinet 4 includes a multistage drawer body.

FIGS. 2 to 5 show the connecting device of the present invention, wherein the top plate 2 as a first member and the leg 3 as a second member.
This is shown as an embodiment in the case of removably connecting. This connecting device includes a stopper 5, a fastener 6 made of a leaf spring, and a receiving body 7 made of synthetic resin or the like. As shown in FIG. While the male screw portion 8 is formed, an annular locking projection 9 is formed on the outer periphery of the tip portion of the shaft portion 5a. The tip of the locking projection 9 is formed in a hemispherical or conical shape.

The fastening device 6 is formed by bending an elastic plate such as a leaf spring. As shown in FIGS.
The left and right sides of the base 6a are bent upward, and the tip is bent inward and downward to form a pair of locking claws 10,10.
As shown in FIGS. 2 to 4, the receiving body 7 has a storage portion 11 having a substantially rectangular shape in plan view into which the fastening tool 6 can be inserted from above, and a guide formed in a downwardly curved shape on both left and right sides of the storage portion 11. Part 1
2 and 12 and a cap 13 connected to the storage section 11 and the guide sections 12 and 12. The outer envelope (see FIG. 4) of the storage portion 11 and the guide portions 12 and 12 in front view (see FIG. 4) coincides with the substantially elliptical mounting hole 14 formed in the inner surface of the leg 3 as the second member. Formed as follows.

Reference numerals 15 and 15 denote a pair of retaining portions provided on one side of the storage portion 11 (the side opposite to the cap 13). When the receiving member 7 is pulled out from the mounting hole 14, the fixing member 6 is used. It is designed to be pulled out integrally so as not to be left in the mounting hole. On the lower surface of the top plate 2, the male screw portion 8 of the stop rod 5 is screwed and mounted in advance so that the locking projection 9 at the tip projects downward. A submerged nut (not shown) to which the male screw portion 8 can be screwed may be attached.

On the other hand, a mounting hole 14 is formed in the leg 3 so that the receiving body 7 can be inserted from the side. A communication hole 16 is formed such that the projection 9 communicates with a substantially central portion of the mounting hole 14. In this case, the storage unit 1 in the receiving body 7
Each dimension is set so that the upper end of the fastener 6 housed in 1 is substantially in contact with the upper surface of the mounting hole 22.

[0013] In this configuration, a stop rod 5 is provided on the lower surface of the top plate 2.
Is attached to the storage portion 11 of the receiving body
Are housed so that the locking claws 10, 10 face upward, and the housing 11 and the guides 12, 12 are attached to the mounting holes 1.
4, the pair of locking claws 10, 10 of the fastening tool 6 face downward below the communication hole 16. When the distal end of the locking rod 5 screwed to the lower surface of the top plate 2 is inserted downward from the communication hole 16, a pair of the fastening tools 6 inserted into the mounting hole 14 at the large diameter portion of the locking projection 9. While the locking claws 10, 10 are deformed against elasticity, the distal end of the locking rod 5 enters between them,
A pair of locking claws 10, 1 at appropriate small diameter portions of the locking projection 9.
0 can be locked, so that the stopper rod 5 is prevented from coming out upward, and the top plate 2 and the leg 3 can be extremely easily connected (see FIG. 6).

When the receiving body 7 is inserted into the mounting hole 14, the cap 13 can close the opening of the mounting hole 14 on the inner side surface of the leg 3, so that the appearance is clear. In addition, as shown in FIGS. 2 and 6, if the notch groove portion 17 is formed in the portion of the cap 13,
When the receiver 7 is pulled out from the mounting hole 14, the gap between the cap 13 and the side surface of the leg 3 is widened by inserting the tip of a tool such as a screwdriver into the notch groove portion 17 and prying the same. It will be easier.

Further, as shown in FIGS.
If the elastic pressing portion 18 whose free end protrudes downward is formed integrally with the bottom plate 11a, the elastic pressing portion 18 of the mounting hole 14 Since the lower surface side is pressed to urge the receiving body 7 upward, it is possible to prevent the body 7 from rattling by hitting in the mounting hole 14. As the mounting sequence, the receiving body 7 may be inserted first into the mounting hole 14 together with the fastener 6, and then the locking rod 4 mounted on the top plate 2 may be inserted toward the communication hole 16.

When a wedge 19 made of synthetic resin or the like as shown in FIGS. 6 and 7 is pushed into the gap between the top plate 2 and the leg 3 in a connected state, the locking rod 5 and the locking claw 10 are pressed. , 10 can be eliminated, and can be fixed more firmly. At this time, if a ridge 20 is provided on the wide surface of the wedge body 19 in a direction orthogonal to the insertion direction, the ridge 2
At 0, the frictional force at the connection point increases, and the slippage and removal of the wedge body 19 can be prevented.

The fastening member 6 may be formed of a synthetic resin material having a large elastic coefficient instead of being formed of a leaf spring made of a metal plate. Needless to say, the two members are not limited to the tabletop and side plates. The depth of the mounting hole 14 in the lateral direction is shorter than the thickness of the leg 3, and
Is formed slightly larger than the shaft portion 5a of the stop rod 5.
It is more convenient to form a groove 21 for the driver at the tip of the stop rod 5.
