DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting a top plate and side plates in a counter or the like.

[0002]

2. Description of the Related Art For example, Japanese Patent Publication No. 1-2486 discloses a method in which a plurality of top plates are arranged side by side between left and right side plates.
A counter is disclosed in which a connection bolt and a nut screwed to the connection bolt are tightened and connected between them.

[0003] In this method, when connecting the side plate and the top plate, the end of the connection bolt protruding from the side end of the top plate is connected to the inner side of the side plate of the double wall structure having the inner plate and the outer plate. The nut is screwed to the face plate and inserted into the nut, and a nut is screwed into the connection bolt from the outside of the fastener to tighten it.

[0004]

In the above-mentioned conventional structure,
In addition to the fastening force of the connecting bolt acting on the fastener just screwed to the inner plate of the side plate, a large load such as the top plate and articles placed on it acts to pull the fastener. However, there is a risk that the inner plate is deformed, the screw of the stopper is loosened, and the stopper is peeled off, and the adhesion between the side end surface of the top plate and the side plate is impaired. Further, there is a disadvantage that the appearance is poor because the stoppers and the like are exposed to the outside.

An object of the present invention is to provide a coupling device which can firmly receive the pulling force of the coupling bolt on the top plate side when connecting the top plate and the side plate, and furthermore, does not expose the parts to the outside and has a good appearance. It is in.

[0006]

According to the present invention, the above-mentioned problem is solved as follows. (1) An open-top box-shaped nut receiving member whose inner end is overlapped with the inner plate is fixed to the inner surface of the outer plate of the side wall of the double wall structure having the inner plate and the outer plate. And a mounting hole having a recessed portion smaller than the width of the head portion and larger than the width of the cylindrical portion of the cylindrical nut having a head portion at the outer end of the cylindrical portion in the overlapped portion of the inner plate and the inner surface plate. Then, the cylindrical nut whose head is locked in the recessed portion of the mounting hole and a connection bolt projecting from a side end of the top plate are screwed and fastened.

(2) In the above item (1), the mounting hole formed in the overlapping portion between the inner surface plate of the leg side plate and the nut receiving member is formed in a flat T-shape having a recessed portion in the middle, so that the support is orthogonal. A mounting bracket for a top plate, comprising an inverted L-shape, and a notch with an open bottom at the bottom corresponding to the recessed part, and the mounting piece being the head of the cylindrical nut. It is arranged so as to be located between the part and the depression part.

As a whole, it has a T-shape that is horizontally long and low. Depression
The width of (5b) is smaller than the head (6b) of the cylindrical nut (6) described later, though it passes through the cylindrical portion (6a). In some cases, the side plate (3) may be composed of only the inner surface plate (3a).

As is apparent from FIG. 2, inside the side plate (3), a box-shaped nut receiving member (open to the top) is provided on the back of the outer surface plate (3b) at a position corresponding to the mounting hole (5). 7) is attached. The nut receiving member (7) is superposed on the inner plate (3a), and is provided between the inner and outer plates (3a) and (3b) from both sides of the vertical base piece (7a) having the same notch as the recess (5b). A side piece (7b) extending outward; and a bent piece (7c) welded to the outer face plate (3b) at the outer end of the side piece (7b), wherein the mounting hole (5) is provided. Surrounds the bottom and sides of the Base piece (7a) and side piece (7
b) A bottom piece (7d) is provided between the lower edges.

FIG. 3 (8) is an inverted L-shaped receiving metal fitting which is inserted from the inside into the mounting hole (5) of the side plate (3). The metal piece is bent at a right angle to the mounting piece (8a). A support piece (8b) is provided, and the mounting piece (8a) is horizontal before insertion.

In the embodiment shown, the mounting piece (8a) is reinforced as double. The width of the mounting piece (8a) is shorter than the width of the horizontal portion of the mounting hole (5), and a cutout (8c) that opens toward the free end is provided at the center thereof. The width of the notch (8c) is the same as that of the aforementioned notch (5b) of the mounting hole (5).
Is equal to the width of The supporting piece (8b) is, as shown in FIG.
(1).

The cylindrical nut (6) is provided at the tip of the cylindrical part (6a), which is the main body, with the width of the notch (5b) of the mounting hole (5) and the notch (8c) of the receiving bracket (8). It has a head (6b) that is larger than the width. As shown in FIGS. 6, 7 and 8, the female screw hole (6c) of the cylindrical nut (6) is connected to the connecting bolt (4) shown in FIG.
Can be screwed into the external thread (4a).

At the time of assembling, first, as shown by the arrow in FIG. 2, the cylindrical nut (6) is placed with its head (6a) first.

【The invention's effect】

(A) The head of the cylindrical nut is engaged with a nut receiving member fixed to the back surface of the outer plate of the side plate, and the inner plate of the side plate is sandwiched between the side end surface of the top plate and the nut receiving member. The inner plate and the outer plate of the side plate are less likely to be deformed when fastening the cylindrical nut and the connection bolt, and the entire side plate is drawn to the side end surface of the top plate, so that the top plate and the side plate adhere to each other. Can be combined. In addition, since the components for mounting the cylindrical nut to the side plate, such as the nut receiving member, are not exposed to the outside, the top plate and the side plate can be joined without impairing the appearance of the side plate. Further, the nut receiving member also serves to prevent the cylindrical nut from falling into the side plate before screwing the connection bolt (the invention according to claim 1).

According to the second aspect of the present invention, the load of the top plate and the articles placed thereon can be directly supported on the inner side plate of the side plate via the receiving bracket.
