A pair of connectors is attached in advance to members that are to be connected to each other, and assembly and disassembly of prefabricated furniture or connection and separation of unit furniture are performed by connecting and separating the pair of connectors. , Conventional connectors require jigs and tools for connection and separation.

The present invention does not require any jigs or tools to assemble or disassemble such assembled furniture or connect or separate unit furniture.
The object of the present invention is to provide a furniture connection device that can be easily and accurately connected without using any tools.

In addition, the present invention provides a first structure that is embedded in two members to be connected to each other with their surfaces exposed and coupled to each other.
and a second connector, the first connector forming a fitting hole and a locking hole on the surface of the frame,
A hook locking portion is provided in the locking hole, and the second connector has a fitting protrusion that fits into the fitting hole on the connection surface side of the member adjacent to the surface of the frame body. is provided protrudingly inside the frame body, and the hook portion at the tip protrudes toward the connection surface side to pivotally support the base of the hook body that engages and disengages from the hook locking portion in the locking hole, and A spring body is provided inside the body to bias the hook body in a direction in which the hook portion is engaged with the hook locking portion, and the hook portion is attached to the surface portion of the frame body. The device is characterized in that an operating lever body that rotates the hook body in a direction in which it is released from the hook body is pivotally supported.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

In FIG. 1, A and B are members of the assembled furniture that are connected to each other, and these two members A and B are the first
and are separably connected by second connectors 1 and 2.

As shown in FIGS. 2 and 3, the first connector 1 connects a large-diameter cylindrical frame 11 and a small-diameter cylindrical positioning body 12 with a triangular connecting piece 13 at the front end thereof. The frame body 11 has a pair of fitting holes 14 on both sides of which the diameter gradually decreases toward the inside, on the surface of the frame body 11. Similarly, the first half of the locking hole 15 gradually becomes smaller in diameter toward the inside, and the second half has a larger diameter.
is formed at the center of the locking hole 1.
A metal round rod 16 serving as a hooking and locking portion is provided in the middle portion of the locking hole 15 in a state in which it is positioned on an extension of the slope 15 _a of the front half of the locking hole 15 and is supported by the frame body 11 at both ends. .

Moreover, a retaining protrusion 17 is formed in parallel on the outer circumferential side of the frame body 11, and the frame body 1
A projection 18 is formed on one side of the surface of the connecting piece 13, and a guide slope _13a is formed on the front half of the edge of the connecting piece 13 on the frame 11 side.

Then, this first connector 1 is manufactured by press-fitting its frame 11 into a large-diameter hole formed in the connection surface of one member A, and inserting the retaining protrusion 17 into the inner wall of the hole. , by inserting the positioning body 12 into a small diameter hole formed in the connection surface of member A.
When press-fitting, the frame 11 is exposed with its surface side exposed.
is embedded and fixed in member A without rotating.

As shown in FIGS. 2 and 3, the second connector 2 has a rectangular flange portion 22 integrally provided at the front end of the large-diameter cylindrical frame 21, and A pair of fitting protrusions 23 that closely fit into each fitting hole 14 of the first connector 1 are integrally provided on one side of the outer periphery adjacent to the surface of the body 21, and The base of the S-shaped hook body 24 is pivotally supported on the other side of the interior, and the hook portion 25 at the tip of the hook body 24 is attached to the frame 21.
The metal round bar 16 of the first connector 1 protrudes between the fitting protrusions 23 on one side of the outer periphery, and the hook part 25 engages with the metal round bar 16 within the frame body 21. A spring body 26 is provided to bias the hook body 24 in the direction in which the hook body 24 is stopped, and the hook portion 25 rotates the hook body 24 in the direction described above from the metal round bar 16 on the surface of the frame body 21. The operating lever body 27 to be moved is pivotally supported.

The frame 21 is made of synthetic resin, and on the outer periphery thereof, except for the one side surface, i.e., the connection surface side, a pair of parallel retaining protrusions 28 are formed, and on the one side surface of the outer periphery, a recess 29 is formed corresponding to the protrusion 18 of the first connector 1.
is provided.

The hook body 24 is made of metal, and has a metal shaft 30 supported at both ends by the frame body 21.
The recess 2 on the S-shaped base side is pivotally supported by
_4a is fitted with the spring body 26.

Further, the spring body 26 is a metal coil spring, and its side portion is supported by a support piece 31 formed on the inner circumferential wall of the frame body 21.

The operating lever body 27 is molded from synthetic resin, and a shaft portion 32 is integrally formed on both sides of the operating lever body 27. The operating portion 34 at one end is fitted into a recess 35 formed on the surface of the flange portion 22, and the driving portion 36 at the other end engages the hook body 24. It is in contact with the recess _24b on the tip side of.

Then, the frame 21 of the second connector 2 is press-fitted into a large-diameter hole formed in the mounting surface adjacent to the connecting surface of the other member B, and the retaining protrusion 28 is attached to the inner wall of the hole. By biting into the member B, the fitting protrusion 23 and the hook portion 25 at the tip of the hook body 24 are embedded and fixed in the member B with the hook portion 25 protruding toward the connecting surface of the member B.

With such a configuration, when connecting members A and B, each fitting protrusion 23 of the second connecting tool 2 is inserted into each fitting hole 14 of the first connecting tool 1, and
The hook portion 25 of the hook body 24 is hooked onto the locking hole 15.
is inserted, and the hook part 25 of the hook body 24 is locked to the round bar 16.

In this case, since the fitting hole 14 gradually becomes smaller in diameter toward the inside, the fitting protrusion 23 can be easily inserted, and the hook portion 25 also fits into the locking hole 15.
Since it rotates along the slope _15a , it can be easily inserted, and just before the insertion is completed,
The frame body 21 is connected by the guide slope _13a of the connecting piece 13.
is guided, and when the insertion is completed, the edge of the connection surface side of the frame 21 is held by the protrusion 18 of the frame 11 and the connecting piece 13, and at the same time, each fitting hole 14 and each fitting protrusion 23 are in close contact with each other, so each connector 1, 2
The connection between the parts A and B can be made extremely strong, and each member A and B can be connected reliably.

In addition, when separating members A and B, rotate the operating part 34 of the operating lever body 27 with your fingertips so as to pull it out from the recess 35 of the flange part 22 of the frame body 21,
Thereby, members A and B can be separated by rotating the hook body 24 and disengaging the hook portion 25 from the round bar 16.

As described above, according to the present invention, when connecting members, if the first and second connectors are attached to the member to be connected, the fitting hole and the locking hole of the first connector are simply inserted. By simply inserting the fitting protrusion of the second connector and the hook part of the hook body, the hook part is locked to the hook part in the locking hole.
It is extremely easy to connect, and the fitting holes and protrusions make the connection reliable and strong.
When separating the components, simply rotating the operating lever body with your fingertip releases the hook part from the hooking and locking part, making it easy to separate the parts. Therefore, no jigs or tools are required. Connection and separation of members can be easily and accurately performed without any problems.
