Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bag frame structure suitable for hanging a dust bag or a laundry bag, and more particularly to a bag frame assembly structure.

[Conventional technology]

Generally, to facilitate the handling of the contents of garbage bags and laundry bags, put a paper or vinyl bag on the inner surface of the bag frame and fold the edge of the bag back to the outside of the metal frame to lock it. It is customary to remove the bag from the bag frame at the same time it is closed.

Moreover, when forming a frame body not only by a bag frame but generally by a metal rod or a metal tube, it is also the same as combining several kinds of them into a three-dimensional structure.

[Problems to be solved by the device]

Generally, the bag frame has few technical difficulties in manufacturing and is easy to produce in developing countries, and in addition, it is necessary to manufacture a product at a very low price in order to have an advantage in product competition due to its use. It is essential to employ a simple coupling structure that uses as few members as possible.

In addition, the frame made by combining the metal tubes is shipped with each part disassembled, so if the fitting of the connecting part is not precise, the overall rigidity will decrease and it will not be useful, but it is made precisely Therefore, not only the manufacturing cost rises, but also the assembly work by the user tends to be difficult.

[Means for Solving the Problems]

The present invention is intended to solve such a problem, to provide a bag frame structure in which the number of parts is small and the assembling work is easy, and the fitting portion is prevented from rotating after the assembly. Two substantially Z-shaped side pipes made by bending steel pipes
A structure in which an end portion of 1a is connected by a rod-shaped connecting member 1b to form a frame, in which the two side tubes 1a, 1a and the connecting member are connected.
One of the members 1b and 1b is bent at the end to be the insertion side A, and the end of the other member B inserted therein is configured as an inclined surface inclined with respect to the longitudinal direction. There is.

[Action]

The two side pipes 1a and the connecting member 1b are made of pipes as parts to be inserted side A, and the other end is inserted and fixed to the bent ends. Since the end portion of the member B on the inserting side is an inclined surface, if the inclined surface is pushed outside with respect to the bent portion on the inserted side, the inclined surface buffers the inner surface of the inserted side A and the insertion is released. Unless it is turned, it is blocked.

〔Example〕

The present invention will be described below with reference to the illustrated embodiment. In the figure, a dust bag C is composed of a metal bag frame 1 and a bag body 2 of paper, vinyl or the like.

As shown in FIGS. 3 and 4, the bag frame 1 includes two substantially Z-shaped side pipes 1a manufactured by bending a steel pipe and two straight tubular connecting members 1b for connecting between both ends thereof. It is assembled by and. The "a" part of the assembled bag frame 1 forms a locking part for locking a paper / vinyl bag, the "b" part forms a base part to be placed on the floor, and both are oblique. They are joined together by the connecting portion “C” installed at, and are prevented from coming off by covering the bag body 2.

The side tube 1a and the connecting member 1b are coupled by fitting.
That is, one of the members A is bent to be the insertion side, and the other end B is inserted and fixed to the inner surface thereof. In the example of FIG. 3, the end portions of the side tubes 1a are bent so as to face each other to be the insertion side A, and a straight tubular connecting member.
1b is the insertion side B. On the contrary, in the example of FIG. 4, the connecting member 1b is made of a steel pipe, and both ends thereof are bent in parallel to form the insertion side A, and the end of the side pipe 1a is inserted as the insertion side B. Engage.

Here, as shown in FIG. 5, the two side tubes 1a and the connecting member 1b are made of a tube, and the end of the side tube 1a and the connecting member 1b are bent. Further, since the end portion of the insertion side B is inclined with respect to the longitudinal direction, if the inclined surface on the insertion side is pushed toward the outside of the bent portion on the inserted side, the inclined surface becomes the inner surface of the inserted side A. It becomes impossible to rotate by buffering.
Therefore, the rigidity of the frame body of the assembled bag frame C is increased.
In addition, the shape of the end portion on the insertion side B does not necessarily need to have a sharpened tip, and as shown in FIG. 6A, only the tip portion may be cut at a right angle to the longitudinal direction. Further, the means for forming the inclined surface is arbitrary, and it is also possible to use cutting or the like, or to indent only a part of the tube inward as shown in FIG.

[Effect of device]

As described above, the present invention comprises the inserted portion A formed by bending the connecting portion of the side pipe 1a and the connecting member 1b and the insertion portion B having the end portion having the inclined surface inclined with respect to the longitudinal direction. Since the inclined surface on the insertion side is pushed toward the outside of the bent portion on the insertion side to be joined, it has a simple structure to be assembled by joining the metal pipes, and moreover, the joining portion rotates after assembling. There is an effect that there is no problem such as being unable to maintain the shape.
