Description

[Detailed Description of the Invention] This invention relates to a connecting fixture that can be used, for example, to efficiently and strongly suspend and support display boards suspended in supermarkets.

For example, in supermarkets and the like, display boards are hung from the ceiling floor to provide information about the store and to clearly indicate where products are advertised and sold.

In this case, there are various types of display boards, ranging from light ones to extremely heavy ones, and therefore, a suspension device that can withstand them is required.

However, with the conventional type, the ceiling decorative board was mounted at a distance below the ceiling floor, and as a result, it was not able to withstand the increased weight. A bolt (rod-shaped body) installed in the board to suspend the board.
It is proposed to support using

In this case, a connecting fixture is provided at the upper end of the link chain on the display board side, and the link chain is connected and fixed to the stud bolt via this, but it is very troublesome to install this fixture, and it may slip off under load. There was also a danger that this would happen.

This invention was proposed in order to eliminate such disadvantages and inconveniences.

The details will be explained below based on the drawings.

FIG. 1 shows the entire suspension device constructed for the purpose of suspending a display board 1. As shown in FIG.

2 is a ceiling floor finished with a strong concrete base, and a large number of bolt-shaped rod-like bodies 3 are vertically implanted and fixed in the bottom part.

A ceiling decorative board 4 is mounted slightly lower through these rod-like bodies 3, leaving a predetermined space between it and the ceiling floor 2.

5 is a board support rod of the display board 1, one of which is shown in the figure, and this support rod 5 is located in the space through a hole in the ceiling decorative board 4.

A chain engagement ring 6 is fixedly installed near the upper end of the support rod 5, and the base end of a link chain 7 is connected to three locations on the outer periphery of the chain engagement ring 6.

The upper end of each link chain 7 is connected and fixed to each rod-shaped body 3 via a connecting fixture 8, which will be described below.

A preferred embodiment of the connecting fixture 8 is shown in FIGS. 2-5.

Among them, 9 is an L-shaped connecting board, 1 is
0 is a flat type prone plywood.

The connecting board 9 has a lower notched groove 11 in the horizontal plate portion 9a, which is a U-shaped long groove that guides and fits the rod-shaped body 3.

At the bottom of the lower notch groove 11, a U-shaped hanging piece 12 is welded to protrude downward, and inverted L-shaped groove-shaped hanging parts 13 are formed at the upper and lower middle parts of the hanging piece 12. .

On the other hand, a wide pivot opening 14 is provided through the upright portion 9b of the connecting board 9, and the proximal end of the prone plywood 10 is pivoted to this opening.

The prone plywood 10 has an upper notch groove 15 cut out in the direction completely opposite to the lower notch groove 11, and has a guide port 16 at the open end thereof. This hanging plywood 10 is
The angle can be freely changed between a state substantially parallel to the bottom surface of the connecting board 9 and a state facing upward, and when the upper and lower notch grooves 15 and 11 are concentrically matched in the parallel state, and the prone plywood 10 is facing upward. The upper notch groove 15 exhibits a so-called twisted state. Then, a spring 17 is interposed between the base ends of both plates 9 and 10, and the ply plate 10 is attached to the connecting board 9.
The top can be opened at will. Note that 18 is a spring holder that fixes the top and bottom of the spring 17, and 19 is a stopper that engages and holds the prone plywood 10 in a fixed upward position.

In this way, the connecting fixture 8 is made of prone plywood 1 whose portion excluding the stopper 19 is formed narrower than the pivot opening 14.
0 through the pivot opening 14 and inserting the spring 17, it can be assembled very easily.

When this is used, the connecting fixture 8 is placed in a horizontal position so that the U-shaped frame space formed by both plates 9 and 10 corresponds to the outer periphery of the rod-shaped body 3 as shown in FIG. The upper notch groove 15 is made to open upward, and the lower notch groove 11 is made to face downward.

Next, in FIGS. 6 and 7, the prone plywood 10 is held parallel to the connecting board 9 by pressing as shown by the arrow P, and the connecting fixture 8 is rotated vertically as shown by the arrow X. , the upper notch groove 15 is fitted into one side of the rod-like body 3, and the lower notch groove 11 and the hook piece 12 are brought into a relationship where they are fitted into the other side of the rod-like body 3. When it is completely inserted, it will be in the state shown in Figures 2 to 5.

In this state, as shown in the third figure, the upper notch groove 15
is twisted around the rod-like body 3, and the spring 17 always biases it in the biting direction, resulting in a biting behavior that can be moved upward to adjust the tension, but cannot be moved downward at all. .

If the upper link 7a of the link chain 7 is turned sideways to the connecting fixture 8 installed in this manner and is inserted into the groove of the hanging part 13, the connecting fixture 8 will be attached to the rod-shaped body 3 as shown in FIG. It is completely locked without being pulled out in the direction of falling.

As explained above, the connecting fixture of the present invention is
One end of both plates 9 and 10 is pivoted so that the connection board 9 and prone plywood 10 face each other so that the angle can be changed freely, and a spring 17 is interposed between both plates 9 and 10 to form the prone plywood. 10 in the direction of expanding away from the connecting board 9, and both plates 9, 10 have cutout grooves 11, which fit into one side and the other side of the circumference of the rod-shaped body 3.
15 are provided in opposite directions to each other, and the sides between the opposing sides of both plates 9 and 10 are opened, and the rod-shaped body 3 is inserted into each notch groove 1.
1, 15. Therefore, as described above, this connecting fixture is first placed in a horizontal position, then the prone plywood 10 is held down by hand to make it parallel to the connecting board 9, and then returned to a vertical position and released. By this, notch grooves 11 and 15 are cut from the side of the existing rigid rod-shaped body 3.
can be inserted easily and quickly. In addition, the connecting fixture is configured such that the prone plywood 10 is expanded apart from the connecting board 9 by the spring 17, and the edge of the notch groove 15 contacts and engages the circumference of the rod-like body 3.
When a tensile load is applied to the connecting fixture by a member 7 such as a link chain, the edge of the notched groove 15 bites into the circumference of the rod-shaped body 3 and becomes strongly engaged, so that it slides down due to the load. Instead, it is firmly fixed.

Further, for example, if the prone plywood 10 is configured with a leaf spring and has its own spring properties to urge the prone plywood 10 to expand, the prone plywood 10 is a plate having spring properties. Therefore, although it is possible to suspend a lightweight object using such a board material, when a heavy object is suspended, it easily deforms and becomes unbearable, resulting in a disadvantage. In this regard, in this invention,
Since the prone plywood 10 is urged to expand by a separate spring 17, the prone plywood 10
When selecting the material, a hard steel plate that can withstand the suspension of heavy objects can be selected.

Furthermore, since the cutout grooves 15 of the prone plywood 10 and the cutout grooves 11 of the connection board 9 are provided in opposite directions, the connection fixing tool is attached to the rod-like body 3 after it is engaged with the rod-like body 3. It can also be reliably prevented from being pulled out (in the opening direction of each notch groove 11, 15).

In this way, the proposed connection fixture can be used from the side without having to insert into the rod 3 from below, especially when suspending a heavy object using the rod 3 already installed in the ceiling etc. It is excellent in that it can be firmly and stably fixed just by guiding it from the ground.

In particular, the proposed connection fixture allows only the prone plywood 10 to be expanded in a direction oblique to the rod-shaped body 3,
Since the connecting board 9 is held in a position perpendicular to the rod-shaped body 3 via the hanging piece 12, unless the prone plywood 10 is pressed on the rigid rod-shaped body 3, it will not move. Downward movement can be completely prevented, and upward movement is possible without holding down the prone plywood 10, making it easy to push up and move.This connection and fixation also allows for upward movement in the ceiling. This has the advantage that the height of the tool can be easily adjusted, contributing to improved workability.

It goes without saying that this connecting fixture 8 can be used for a variety of purposes other than the above-mentioned display.

In addition, we are planning to make changes such as making the prone plywood 10 side L-shaped as shown in FIG. 8, or forming both plates 9 and 10 with square-shaped plates. Furthermore, as shown in FIG. 9, for the spring receiver 18, both plates 9 and 10 may be stopped in a parallel relationship to form a screw-type stopper for easy and reliable mounting, or each plate 9 and 10 may be individually hammered. It may also be formed by an integrated protrusion. The link chain 7 may also be a rod-shaped body, a string, or other material. In addition, in the illustrated example, the link chain 7 is also used as a locking means, and a great effect can be achieved as an embodiment. It is also planned to configure a dedicated locking means separately from the link chain 7. Further, the connecting member 7 may be pivoted using a hinge.
