[Detailed description of the device]

[0001]

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.
Two plates consisting of a stop rod formed by forming a plurality of annular locking projections on the tip of a shaft body with a large diameter head at appropriate intervals in the axial direction, and an elastic locking plate having a radiation groove. There is disclosed a configuration in which a stop rod is inserted into a through hole formed in a member having a ring shape, and a radiation groove in the elastic locking plate is locked to a locking projection of a tip end 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 in that the fastener cannot be located in the middle of the wall thickness of the member, and it is difficult to mount the fastener at 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 of the present invention is a device for connecting a first member and a second member in furniture or the like, in which a base end of a shaft portion is a first member. One of a stop rod and a flat annular elastic plate body, which is attached to a member so as not to come off, and a plurality of annular locking projections are formed on the outer periphery of the tip end of the shaft portion protruding from the first member at appropriate intervals. And a pair of locking claws that are opposed to each other in the cut-out portion that is separated from each other and are bent in the inner diameter direction of the flat annular elastic plate body, and the second member includes the fastener. Is formed into a locking hole that can be inserted from the side, while the end surface of the second member is provided with a leading end portion provided with a locking projection of the locking rod in the locking hole. A communication hole that can be inserted between the locking claws is formed.

[0006]

With this configuration, if the fastener is previously inserted into the locking hole formed in the side surface of the second member,
This fastener does not fall off. The tip end portion of the retaining rod projectingly provided on the first member is inserted from the communication hole of the second member toward the retaining hole, and the retaining protrusion of the retaining rod engages the pair of retaining claw portions of the retaining fitting. When pressed, the pair of locking claws can be locked to the small diameter side of the locking projection after the locking claws are once separated due to the elastic deformation of the annular elastic plate body itself which is partially cut off in the fastener. .

Therefore, by using the connecting device of the present invention, the two members can be connected very easily and the usability can be significantly improved. Further, there is an effect that the entire connecting device can be downsized.

[0008]

[Embodiments] Next, embodiments embodying the present invention will be described. FIG. 1 is a perspective view of a unit desk. The bookcase 1 is composed of a main plate 2, a top plate 3, a pair of side plates 4 and 4, a central partition plate 5, a plurality of shelves 6 and the like. Items such as books can be taken in and out. Further, the shelf plate 6 can be changed in vertical position by a conventionally known structure. For example, support pins (not shown) are inserted into four front, rear, left and right locking holes at the same height among the locking holes formed in the inner surface of the side plate 4 and the inner surface of the vertical partition plate 7 at appropriate vertical intervals. The shelf 6 is supported by one support pin.

A pair of left and right desk top plates 8 and 8 are detachably mounted on the upper and lower midpoints of the bookcase 1 and side cabinets 9 and 9 which are appropriately spaced on both left and right sides of the bookcase 1. Place and lock with bolts or locking pins. Each side cabinet 9 is provided with a multistage drawer body. Reference numeral 10 is an auxiliary table arranged on the outer surface of the bookshelf 1 on one side.
Is attached.

2 to 6 show the coupling device of the present invention,
An example is shown in which the desk top plate 8 as the first member and the side plate 13 of the side cabinet 9 as the second member are detachably connected. This connecting device is a stop rod 1.
4 and a stopper 15 made of a leaf spring. A male screw portion 16 is formed at the base end of the shaft portion 14a of the stopper rod 14, while an annular locking projection is formed on the outer periphery of the tip end portion of the shaft portion 14a. A plurality of 17 are formed at appropriate intervals. The tip of the shaft portion 14a is formed in a hemispherical shape or a conical shape.

The fastener 15 is provided with a pair of locking claws 19 and 19 facing each other in a cutout portion obtained by cutting off a part of the flat annular elastic plate member 18 in the direction of the inner diameter of the flat annular elastic plate member 18. Let me prepare. On the lower surface of the desk top plate 8, a female screw portion 20 to which the male screw portion 16 of the stop rod 14 can be screwed is formed on the inner periphery, and a sunk nut 21 having a male screw portion on the outer periphery is mounted.

On the other hand, the side plate 13 is formed with a locking hole 22 into which the fastener 15 can be inserted from the side, while the side plate 1 is formed.
A communicating hole 23 is formed in the upper end surface of the hole 3 so that the tip of the retaining rod 14 provided with the locking projection 17 communicates with the substantially central portion of the locking hole 22. In this case, the vertical dimension (H
The vertical dimension (H2) of the locking hole 22 is slightly shorter than that of 1), while the locking hole 2 is smaller than the horizontal dimension (L1) of the fastener 15.
The lateral dimension (L2) of 2 is formed to be slightly larger.
As a result, when the fastener 15 is inserted into the locking hole 22,
The elastic plate 18 resists its own elastic force, and the locking claw portion 1
When the 9 side and the opposing portion are elastically deformed into a more flat shape and are inserted into the locking holes 22, the upper and lower outer surfaces of the elastic plate body 18 are pressed against the upper and lower inner surfaces of the locking holes 22 and carelessly performed. It does not fall off from the locking hole 22.

Further, the depth of the locking hole 22 in the lateral direction is made shorter than the thickness of the side plate 13, and the diameter of the communication hole 23 is set to the stop rod 14.
It is formed to be slightly larger than the shaft portion 14a. It is convenient to form a slot 24 for a driver at the tip of the stop rod 14. In this structure, the locking hole 22 of the side plate 13 is
When the stopper 15 is previously inserted in the lateral direction so that the locking claws 19 and 19 are on the upper side, the pair of locking claws 19 and 19 of the stopper 15 are located below the communication hole 23. At, you will face downward. Then, when the tip end of the retaining rod 1 screwed to the lower surface of the desk top plate 18 is inserted downward from the communication hole 23, the retaining fitting inserted into the retaining hole 22 at the large diameter portion of the retaining ridge 17. A pair of locking claws 19, 19
While deforming against the elasticity, the stop rod 1
4, the pair of locking claws 19 and 19 can be locked at an appropriate small-diameter portion of the locking projection 17, so that the locking rod 14
The desk top plate 8 and the side plate 13 can be connected to each other very easily by preventing them from coming out upward.

The diameter of the communication hole 23 is the shaft portion 1 of the stop rod 14.
By being slightly larger than the diameter of 4a, the mounting position error can be absorbed, while the lateral dimension of the locking hole 22 is formed slightly larger than the lateral dimension of the fastener 15, so that the locking ridge 17 of the locking rod 14 is formed. It is possible to allow movement of the fastening device 15 when the pair of locking claw portions 19 and 19 are fitted and locked. In addition, instead of forming the fastener 15 with a leaf spring body made of a metal plate,
It may be molded with a synthetic resin material having a large elastic coefficient. Further, instead of the male screw portion 16 of the stop rod 14, a large-diameter head continuous with the shaft portion 14a may be engaged with the other side surface of the first member (desk top plate 8 or the like). It goes without saying that the two members are not limited to the desk top plate and the side plate.

The coupling device shown in the embodiment of FIGS. 7 and 8 is
An annular locking projection 26 having a small diameter is formed on the outer periphery of the tip end of the stop rod 25 which is provided on the desk top plate 8 so as not to come off. The side plate 13 is formed with a locking hole 27 on its side surface so that the side plate 1
A communication hole 28, which communicates with the locking hole 27, is formed in the upper end surface of 3. Reference numeral 29 is a fastener having an L-shaped cross section, and a bifurcated locking claw portion 30 is provided at the tip of the lateral plate thereof. In advance, fastener 29
The side plate 1 after inserting the fastener 29 into the locking hole 27 from the side.
It is fixed to 3 with screws 31. Further, the retaining rod 25 protrudingly provided on the lower surface of the desk top plate 8 is inserted into the communication hole 28, and in the retaining hole 27, the retaining protrusion 26 at the tip of the retaining rod 25 is retained by the retaining claw portion 30. When it is locked so as to be held at, the desk top plate 8 and the side plate 1
3 and 3 can be connected inseparably.
