Description

[Detailed description of the invention] (Industrial application field) This invention connects a support frame that supports the top of furniture such as counters, tables, commercial countertops, and sinks with legs made of pipe material. Concerning a new structure for

(Prior art) Conventionally, the legs of a connecting fitting were fitted into the upper ends of legs made of round pipe material, and the ends of the frame material for supporting the top plate were fixed to the horizontally extending support arms of the connecting fitting. 2. Description of the Related Art Furniture is known in which a rectangular top plate support frame is constructed, a top plate is supported on the top plate support frame, and the two are connected.

(Problem to be solved by the invention) In such furniture, since the load from the top plate applied through the top plate support frame is received only by the support arms of the connecting fittings, the mounting base of the support arms There was a risk that the support arm would break due to the load being applied to it. In addition, the use of connecting fittings with a complicated structure increases the cost of the product and also makes it difficult to assemble the product.

(Means for solving the problem) This invention is an attempt to solve the drawbacks of the connection structure between the top plate and the legs in conventional furniture. A groove 3 extending a certain length along the direction is provided, and a vertical groove 3 abutting against the side surface of the leg 1 is provided at the tip of the support frame 2 which is connected to the upper part of the leg 1 and extends in the horizontal direction to support the top plate. A connecting piece 4 is extended, and the concave groove 3 is formed in the connecting piece 4.
It is characterized in that a protrusion 5 that engages in the groove 3 is provided in a protruding manner, and while the protrusion 5 engages in the concave groove 3, the connecting piece 4 is brought into contact with and fixed to the side surface of the leg 1.

(Embodiment) The drawing shows a preferred embodiment of this invention, and in the drawing, 1 is a furniture leg made of a square pipe, and 2 is a support frame fixed horizontally to the upper end of the leg 1. , the support frame 2 is made of a cross-sectional shape.

A groove 3 extending longitudinally from the upper end of the leg 1 is formed in an adjacent side surface of the upper part of the leg 1. Support frame 2
As shown in the figure, a connecting piece 4 extending from the tip of the vertical plane is provided at both ends of the connecting piece 4, and a protrusion 5 that engages in the groove 3 is provided on the connecting piece 4 in a protruding manner.

The support frame 2 is horizontally joined to the upper part of the leg 1 while the protrusion 5 is engaged in the groove 3, and both are fixed with set screws 6. In this way, by spanning and connecting the support frame 2 to the four legs 1 arranged at the corners of the rectangle, a rectangular horizontal support frame is constructed, and a top plate is placed on the top of this support frame. are placed and combined by desired means to construct furniture. Reference numeral 7 denotes a support piece extending from the tip of the upper surface of the support frame 2, which contacts and supports the upper surface of the leg 1 when connected.

However, this support piece 7 is not necessarily necessary, and the tip end surface 8 may be brought into contact with the side surface of the leg 1 and fixed with a set screw 9, as shown in FIG. still,
The support frame 2 shown in FIG. 3 is constructed of a square pipe or a cross-shaped section.

Due to the engagement between the groove 3 and the protrusion 5, the couple generated between the leg 1 and the support frame 2 due to the load applied to the support frame 2 is absorbed by the groove 3 and the protrusion 5. , there is no fear that the support frame 2 will deform with respect to the leg 1.

(Effect of the invention) According to the connection structure between the top plate and the legs in the furniture of this invention, a groove 3 extending a certain length along the longitudinal direction of the leg 1 is formed in the upper part of the leg 1 made of a square pipe. , a vertical connecting piece 4 that comes into contact with the side surface of the leg 1 is extended at the tip of a support frame 2 that is connected to the upper part of the leg 1 and extends horizontally to support the top plate;
A protrusion 5 that engages the groove 3 is provided protrudingly on the groove 3.
Since the connecting piece 4 is fixed in contact with the side surface of the leg 1 while the protrusion 5 is inserted into the ridge 5, the support frame can be connected to the upper part of the leg with an extremely simple structure to support the top plate. In addition to being able to form a frame, even if the support frame receives a load from the top plate, there is no fear that the support frame will rotate and deform with respect to the legs because the protrusions are engaged in the grooves. In addition, since the protrusions are inserted into grooves of a certain length, it is possible to achieve a certain positioning without the need for other members, and the grooves and protrusions can be simply pressed together. It can be easily formed by molding.
