Description

[Detailed description of the invention] This invention relates to a light metal Hina tier, and its purpose is to provide a folding or stationary, multi-tiered or single-tiered light metal chaise longue that is strong when assembled and easy to disassemble and store. The purpose of the present invention is to easily provide a light metal chick stage.

Light metal chick tiers are commonly used as photographic scaffolding when taking group photographs.

Among such light metal chick tiers, multi-tiered and foldable light metal banquettes are generally preferred for use when taking group photographs.

These light metal chick tiers generally have the advantage of being light in weight and easy to transport, but it is usually difficult to join the bars in the orthogonal direction (for example, the upper and horizontal bars), and it is difficult to weld them together, for example, by welding. It is necessary to remove the surface protective film, and the welded parts have the disadvantage of corroding and deteriorating during use.In addition, when joining with screws and bolts, the assembly work is complicated, and it is necessary to place an angle material on the joint part before screwing or bolting. Although it is suitable for assembly work in factories, etc., it has various drawbacks such as the fact that it cannot be reassembled once it is disassembled for storage after purchase by a general consumer.

This invention was made to solve these conventional drawbacks, namely, the inside surface of the upper end of the vertical bar is a notch surface to form a fitting part, and the upper surface of the upper bar has edges on both sides. It is made up of a wide plate with a width of 100 mm, and an engagement protrusion is provided on the top surface of this plate.Bis pockets are installed inside the corners of both sides of the upper crosspiece, and the upper crosspiece is attached to the fitting part of the upper end of the vertical crosspiece. This relates to light metal chick stages that are fitted together and screwed together from the upper end of the outer surface of the vertical bar toward the bis pocket of the upper bar.

Embodiments of this invention will be described below based on the drawings.

These vertical bars 1, upper bars 2, lower bars 3, and the connecting upper bars 4, connecting lower bars 5, or other vertical bars 6 used in the case of making a multi-tiered light metal chaise longue are each hollow light metal square columns made of aluminum or the like. Consisting of

Reference numeral 7 indicates a joint material, and this joint material 7 is expandable and retractable and is used for a foldable light metal chick stage.

When the joint material 7 is an extensible member, its extensible structure is not particularly limited, and even when it is of a fixed length, the joint structure with the vertical beam 1 is not limited in this invention. See Figures 1 and 2.

In FIGS. 3A and 3A to 4A and 4B, reference numeral 8 designates pins erected on the top plate 10, which is a wide plate having edges 9 on both sides of the top crosspiece 1.

In the illustrated embodiment, two pins 8 are erected at each end, but the number and position of the erected pins are not limited.

However, as shown in Fig. 6, we have adopted a usage method in which two pairs of chick tier frames A are used, only the seat plate 11 is spanned between the frames B, and the chick tiers are extended in the horizontal direction as three chick tiers. In this case, it is desirable that two pins 8 be provided upright at each end.

Also, this pin 8 is connected to the engagement hole 12 (9th
(see Figure A) to fix the seat plate 11 between the upper crosspieces 2, 2.

By fixing this seat plate 11 between the upper crosspieces 2, 2, there is also a reinforcing effect for the entire framework.

13 is a bis pocket, this bis pocket 13
are provided at the inner corners of both sides of the upper crosspiece 2.

In this embodiment, the bis pockets 13 are provided at four inner corners of the upper crosspiece 1, but the invention is not limited to this embodiment.

Reference numeral 14 denotes a fitting portion provided on the inner surface of the upper end of the vertical bar 1, and this fitting portion is formed by a notch 15 cut out from the inner surface of the vertical bar 1.

Incidentally, 16 and 17 are punched holes for joining the connecting upper crosspiece 4 and lower crosspiece 3, respectively, and these punched holes 16 and 1
7 is formed on the inner surface of the vertical bar 1.

Further, punched holes 17 are also formed in the lower part of the outer surface of the vertical bar 1, and are used for joining other horizontal bars.

The ends of the connecting upper crosspiece 4 and lower crosspiece 3 that fit into the punched holes 16, 17, and the connecting lower crosspiece 5 that fit into the punched hole 17 formed at the lower part of the outer surface are the fourth
As shown in the right end portion 18 of the connecting upper crosspiece 4 in Figure A, the upper surface plate 1
The edge 9 of 0 is cut out to form punched holes 16, 17,
It is possible to fit into the

Further, bis pockets (not shown) are formed at the inner corners of the ends of the upper and lower connecting bars 4, 3, and 5, if necessary.

In addition, 19 are screw holes, respectively.

In the light metal chaise lounge of this invention having such a structure, first, the end of the upper crosspiece 2 is fitted into the fitting part 14 of the vertical crosspiece 1, as shown in FIGS. 7A, B, C, and D.

The edge 9 of the upper crosspiece 2 is locked to the upper end surface of the vertical crosspiece 1, and the downward load is received by this edge 9 and the upper end surface of the vertical crosspiece 1.

Thereafter, using or not using the screw holes 19, the vertical crosspiece 1 is fixed with screws 20 from the outer side toward the screw pocket 13 of the upper crosspiece 2.

Also, to connect the vertical bar 1 to the upper and lower connecting bars 4, 3, and 5, cut off the edge 9 as shown in the right end 18 in FIG. 4A and insert the end into the punched hole 16. Then, they can be joined according to the above-mentioned method of tightening the screws 20. (See Figure 7D) Of course, in the case of non-foldable light metal chick tiers, a horizontal bar is required (this is not particularly shown), but in this case as well, the connection of the upper bar 2 and the connection of the connecting bar 2 are necessary. Follow legal.

Furthermore, even in the case where there are a plurality of connected upper and lower crosspieces in a multi-stage configuration, the above-mentioned joining method may be followed.

Finally, attach the pin 8 provided on the upper crosspiece 2 to the seat plate 11.
The seat plate 11 is inserted into the engagement hole 12 (see FIG. 9A) to fix the seat plate 11 between the upper crosspieces 2, 2.

By being fixed between the upper crosspieces 2, the seat plate 11 also serves to reinforce the entire framework of the crosspieces.

In this way, the light metal chick stage according to the present invention is completed.

In addition, FIGS. 8A and 8B show an embodiment of the expanding tool 21 for regulating the opening angle of the joint material 7. A dowel 21b is provided protruding from the fixed expanding tool 21a for fixing the vertical beam 1, and this dowel 21b is used as a guide. The guide groove (or kerf) 21 moves along the groove (or kerf) 21d.
The joint material 7 can only be expanded by an angle of 90 degrees due to the regulation d, and if it is expanded by an angle of 90 degrees, the expansion mechanism is made up of a receiving expander 21e that stops the subsequent expansion amount by a stopper 21c. The opening tool 21 is shown.

The fixed expanding tool 21a and the receiving expanding tool 21e may have their attachment states reversed.

If the opening angle of the joint material 7 is limited to 90° in this way, when installing or removing the seat plate 11,
Since the work can be carried out while the framework is accurately maintained in a U-shape, the use of the chick tier becomes simple and convenient.

FIG. 9A shows the back side of the seat plate 11, and the strength of the seat plate 11 is determined by folding the edge 11a and the horizontal crosspiece 1.
By forming the seat plate 1b only, when storing the seat plate 11, as shown in FIG. 9B, two sheets are laminated and the seat plate 11 is
It is convenient because it can be made as thick as one sheet of paper.
