Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art For example, in Japanese Examined Patent Publication No. 1-12486, a plurality of top plates are arranged side by side between left and right side plates,
A counter is disclosed in which the mutual connection is achieved by tightening a connecting bolt and a nut screwed to the connecting bolt.

In this structure, when connecting the side plate and the top plate, the end portion of the connecting bolt projecting from the side end of the top plate is inserted into the stopper fitting screwed to the side plate, and the nut is attached from the outside of the stopper fitting. Is screwed into the connecting bolt and tightened.

[0004]

In the above-described conventional structure, not only the tightening force of the connecting bolts acts on the fasteners that are simply screwed to the side plates, but also the top plate and the articles placed thereon. The large load of acts to pull the stopper, loosening the screw of the stopper,
In the worst case, the stopper may be broken and separated from the side plate, and further, there is a problem that the top plate end hangs down or a gap is generated between the top plate and the side plate. In addition, since there are many screw-fastened portions, the number of assembling steps is large, and the screw-fastened portions of the fasteners are exposed to the outside, impairing the appearance.

An object of the present invention is to firmly receive a pulling force by a connecting bolt on the top plate when connecting the top plate and side plates in a counter or the like, and moreover, to receive a vertical load on the top plate without difficulty. The object of the present invention is to provide a coupling device that can be assembled and is easy to assemble.

[0006]

According to the present invention, the above-mentioned problem is solved as follows. A flat T-shaped mounting hole formed in the upper part of the side plate and having a recess in the middle,
A long tubular nut that has a head larger than the width of the recess, and extends substantially horizontally from the head inserted into the flat T-shaped mounting hole through the recess.
It is composed of a mounting piece and a supporting piece which are orthogonal to each other, is an inverted L-shape, and the mounting piece is provided with a notch corresponding to the recess and opening to the free end side, and the mounting piece is attached to the head of the tubular nut. And the metal fitting to be inserted into the mounting hole so as to be located between the mounting hole and the recessed portion, and extending from the side end of the top plate toward the recessed portion of the mounting hole of the side plate, and the tip end of the cylinder. It has a long connecting bolt screwed into the shaped nut.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a counter (A) according to the present invention has a side plate (a) at the end of a main body (2) with a single or a plurality of parallel top plates (1). 3) is attached, and for connection thereof, a horizontally long connecting bolt (4) arranged so as to pass through the lower portion of the top plate (1) is used.

As shown in FIGS. 2 to 8, the side plate (3) comprises an inner face plate (3a) and an outer face plate (3b), and a mounting hole (5) is formed in the upper part of the inner face plate (3a). It is set up. This mounting hole (5)
The lower part of the horizontal part (5a) has a recess (5b) in the middle.
As a whole, it has a horizontally long, low-profile T-shape. Depression
The width of (5b) is smaller than that of the head portion (6b) of the tubular nut (6), which will be described later. 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), behind the outer plate (3b), at the position corresponding to the mounting hole (5), a box-shaped nut receiving member (upper surface open) is formed. 7) is attached. The nut receiving member (7) is overlapped with the inner surface plate (3a) and has a notch having the same shape as the recessed portion (5b) From both sides of the vertical base piece (7a) to the inner and outer surface plates (3a) (3b). A side piece (7b) extending outward is provided, and a bent piece (7c) to be welded to the outer surface plate (3b) is provided at the outer end of the side piece (7b), and the attachment hole (5) is provided. It surrounds the bottom and sides of the. Base piece (7a) and side piece (7
A bottom piece (7d) is provided between the lower edges of b).

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

In the illustrated embodiment, the mounting piece (8a) is double reinforced. The width of the mounting piece (8a) is shorter than the width of the horizontal portion of the mounting hole (5), and a notch (8c) opening in the free end direction is provided at the center thereof. The width of this notch (8c) is the same as the drop (5b) of the aforementioned mounting hole (5).
Equal to the width of. The support piece (8b) is a top plate as shown in FIG.
You will receive (1).

The tubular nut (6) has the width of the recessed portion (5b) of the mounting hole (5) and the cutout portion (8c) of the receiving metal fitting (8) at the tip of the tubular portion (6a) which is the main body. It has a head (6b) larger than its width. As shown in FIGS. 6, 7 and 8, the female screw hole (6c) of the tubular nut (6) has the connecting bolt (4) shown in FIG.
It can be screwed onto the male thread (4a) at the end of the.

In assembling, first, as shown by the arrow in FIG. 2, the cylindrical nut (6) is placed with its head (6a) first.
The upper part of the recess (5b) of the mounting hole (5) and the horizontal part (5
At the point of contact with a), it is inserted inside the side plate (3), that is, inside the box-shaped nut receiving member (7).

Then, as shown in FIG. 3 to FIG.

【The invention's effect】

(a) The head of the tubular nut is inserted inside the side plate and contacts the mounting piece of the receiving metal fitting. Therefore, by fastening the connecting bolt of the top plate and the tubular nut member, the side plate and the receiving metal fitting are also connected. It is attracted to the top plate side, the top plate and side plate are brought into close contact,
Can be firmly bonded. That is, since the mounting piece of the receiving metal fitting is interposed between the inner surface plate of the side plate and the head portion of the tubular nut, the local attraction force of the head portion of the tubular nut applied to the inner surface plate of the side plate is: It is widely dispersed on the inner plate of the side plate, and the inner plate can be attracted to the top plate as a whole.

(B) By fastening the connecting bolt and the tubular nut member, the receiving metal fitting is also firmly fixed, the top plate can be supported by the supporting piece, and the load is directly transmitted to the side plate at the lower end of the depression. Therefore, sufficient strength can be obtained even with a downward load on the top plate.

(C) When the tubular nut is attached to the side plate, screwing is not necessary and the mounting piece of the receiving metal fitting is not exposed to the outside, so that the assembly is easy and the appearance is good.
