[0009]
Steel desks such as office desks and study desks mass-produce top plates, legs, sleeves, curtains, etc., and assemble them by screwing them together at the factory assembly line and packaging them in the final finished product state. Shipped or disassembled finished products into major parts and shipped, stocked at each sales agent, and assembled at the sales destination. Therefore, it is necessary to provide a line for the assembly in the factory, or to assemble at the sales agent, the customer's office, etc. Don't be. In order to solve this inconvenience, there is a connecting device that does not require screwing as described in the section of the prior art. However, this conventional technique also has a problem.
[0010]
What solved this problem is the connector of the present invention. A specific embodiment for connecting the connector of the present invention to a table top and a leg or sleeve cabinet will be described in detail with reference to FIGS.
[0011]
FIG. 1 is a perspective view showing a steel desk 1 that is assembled by using a connector for connecting the top plate of the present invention to legs and sleeve cabinets. In the figure, 2 is a top plate, 3 is a leg, Reference numeral 4 denotes a sleeve cabinet having a plurality of drawers. FIG. 2 is a perspective view showing a state in which the connector 7 is attached to the attachment holes 5 of the leg 3 or the sleeve cabinet 4 and the attachment holes 6 of the top plate formed in the reinforcing plate 8 of the top plate. Sectional drawing of the state connected and fixed with the connector 7 from the state of each is shown.
And this invention is applicable to various things, if it is an assembly article which connects two members.
[0012]
Here, the connection between the top plate 2 and the leg 3 of the steel desk 1 will be described in detail as a specific embodiment of the present invention.
When the top plate 2 and the leg 3 are connected on the connecting surface side, the top plate mounting hole 6 is formed in the top plate reinforcing plate 8, and the mounting hole 5 is formed in the leg 3. In this embodiment, a top plate mounting hole 6 is formed in the reinforcing plate 8 formed in the periphery of the top plate 2 so that the locking claw 9 of the connector 7 can be locked, and the connecting surface of the leg 3 to the top plate 2 is formed. A mounting hole 5 for attaching the connector 7 is drilled.
[0013]
The mounting hole 5 engages with a narrow guide hole 11 on which the guide rail 10 formed on the bottom surface of the connector 7 can slide and guide, and a detent claw 12 formed on the bottom surface of the connector 7. The narrow cutout hole 13 is formed.
[0014]
Next, the connector 7 will be described in detail with reference to FIGS.
The connector body 14 is integrally formed of synthetic resin and has a rectangular cross section and is laid sideways. A reinforcing wall 15 is formed at the center of the connector body 14. A notch 18 is formed so that a part on the side of the locking claw 9 attached to the plate 2 is cut out, and the locking claw 9 is provided on one of the outer sides of the connector main body 14.
[0015]
Further, one side (corresponding to the bottom side in this embodiment) of the rectangular tubular connector main body 14 is extended to integrally form the plate member 16 so that the plate member 16 can use an elastic restoring force. Further, a detent pawl 12 is formed at the end of the plate member 16, and a guide hole 17 for removal is inserted in front of the detent pawl 12 so that a rod-shaped member, for example, a tip end of a screwdriver or the like can be inserted. Make a hole with a diameter that can be stopped. And the guide rail 10 is formed in the bottom part of the square cylinder-shaped connector main body 14. FIG.
[0016]
Here, the connection between the top plate 2 and the leg 3 of the steel desk 1 will be specifically described. The guide rail 10 formed on the bottom portion of the connector main body 14 is inserted into the mounting hole 5 formed on the leg portion 3 and inserted and fixed while being slid to the guide hole portion 11 side (the plate member 16 has an elastic restoring force at this time). Because it is made of a certain material, slide the upper part of the leg 3 in a slightly bent state). Then, the detent pawl 12 provided at the end of the plate member 16 engages and is fixed to the narrow notch 13 formed in the attachment hole 5 of the leg 3.
[0017]
As described above, when the connector 7 is attached to the leg 3, when the top plate 2 is pushed down from above while aligning, the notch 18 in which the wall 15 of the connector main body 14 is not cut is formed. For this reason, it engages with the mounting hole 6 of the top plate drilled in the reinforcing plate 8 of the top plate 2 while causing slight deformation, and can be locked and connected. Thus, it can be connected and fixed without any need for screwing or the like.
[0018]
Further, in order to adapt to the mounting hole 6 of the top plate, positioning can be easily performed by providing a guide 19 as shown in FIG. Furthermore, when product strength is particularly required, there is no deviation with respect to the force in the front-rear direction because the connector 7 is attached to the front and rear of the top plate 2. And with respect to the force of an up-down direction, there is no shift | offset | difference by latching with the attachment hole 6 of the top plate before and behind the top plate 2, and the latching claw 9 of the connector 7. FIG. In addition, with respect to the force in the left-right direction, the guide 19 indicates that there is a possibility that the top plate mounting hole 6 and the latching claw 9 may be scratched from the top plate mounting hole 6 in the case of strong rattling. It can be prevented by guiding.
[0019]
Moreover, the guides 19 are preferably provided at four locations in the A part of FIG. In addition, you may provide four or more places including B part. The groove 20 illustrated in FIGS. 2 and 3 may be omitted, but if the groove 20 is formed, the stress on the locking claw 9 can be dispersed.
[0020]
Next, removal of the connector 7 will be described with reference to FIG.
While inserting a rod-shaped object, for example, a screwdriver or the like, into the guide member 17 formed in the plate member 16 of the connector main body 14 by pushing up the plate member 16, It can be released by removing the thickness of the leg 3 and shifting the connector 7 so as to shift the driver or the like sideways.
[0021]
In addition, if it is a rod-shaped thing instead of this removal guide hole 17, for example, what can be shifted by a driver etc., a function will be performed similarly also in a recessed part or a convex part.
[0022]
