Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling type simple shelves for assembling a plurality of members formed by bending steel pipes or wires.

[0002]

2. Description of the Related Art Conventionally, a simple bookshelf used in hotels and company lobbies, for holding newspapers for several days by a narrow sandwich frame and suspending them, is well known. That is, the conventional simple shelves are formed by extruding an aluminum alloy or bending a steel plate to form a member using a so-called angle material having an L-shaped cross section,
They are assembled with bolts and made into a substantially rectangular frame.

[0003]

However, in such a conventional simple shelves, it is difficult to inexpensively manufacture the members constituting the shelves, the number of parts is large, and the assembly is not easy. The goods themselves were expensive.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In the figure, 1 is a simple shelves according to the present invention, and a main frame 2 thereof has a pair of left and right side frames 2a, 2b formed by bending a steel pipe (including a stainless steel pipe) into a substantially Z shape as shown in FIG.
Are connected at both ends by connecting pipes 2c. Reference numeral 3 is a wire magazine receiving frame suspended from the outer surface of the main frame 2.

The magazine receiving frame 3 is suspended outside one or both of the side frames 2a and 2b. That is, the magazine receiving frame 3, as shown in Figure 5, the upper end portion disposed parallel to the longitudinal member 3b of multiple forming a hanging engagement portion 3a is bent downwardly, connected at a transverse connecting member 3c and to configure
Oh Ru. In this embodiment, the connecting member 3c is the vertical member 3b.
A rectangular shape made by thin wire made of a hard steel wire Similarly diameter of about 5mm and, in one side of that, is welded to the <br/> plurality of longitudinal members 3b, together determine their position, the four The magazine receiving plate 3e is supported by the hole 3d having a rectangular shape. The magazine receiving plate 3e is formed by bending a steel plate or a synthetic resin plate into a U-shape with the upper side opened, and is supported by the connecting member 3c by a downward engaging eave 3f provided on one side, and the other end extending upward is formed. Apply to the vertical member 3b and rotate
Ru detent Shi Thea to be no.

Here, the connecting structure of the connecting portion 4 between the side frames 2a, 2b and the connecting pipe 2c will be described. As shown in FIG. 4, the pipe forming the side frame and the connecting pipe 2c are made of a pipe material having the same diameter and the same wall thickness. That is, both end portions of the side frames 2a, 2b bent inward are pressed spherically from the outer surface to form hemispherical projections on the inner surface of the pressing portion 4a, while corresponding ends of the connecting pipe 2c are formed. The parts are reduced in diameter (swaging) to a diameter slightly smaller than the inner diameters of both ends of the side frames 2a and 2b, and the groove 4 in the axial direction is formed on the outer periphery of the reduced diameter.
b is formed. Incidentally, the concave groove 4b is shallow as proceeds endless surfaces to the deepest center, thus connecting pipe 2c side frame 2a, when inserting into the end of the 2b, initially can be inserted loosely, the hemisphere As the projecting part of the groove advances toward the shallower side of the concave groove 4b, the gap disappears, and finally the connecting pipe 2
c is led to the elastic deformation, the insertion is prevented.

In assembling the main frame 2, first, one of the side frames 2a is placed on the floor with the end portion facing upward, and the concave groove 4 of the connecting pipe 2c is placed therein.
Align b with the protrusion 4a on the inner surface and insert it firmly and firmly to fix it. Next, the connecting pipe 2 standing the other side frame 2b
After fitting it in c, hit it with a wooden hammer or palm to fix it so that it will not come out or rotate. Figure 3 shows the thus set only erected main frame 2. The caster wheels 2 attached to the main frame 2
d is not an indispensable structure in the structure of the present invention, but a bookcase
It is not necessary to attach it when it is used in a stationary state .

Thus, the magazine receiving frame 3 made of wire is hung on the side surface of the assembled main frame 2 at the suspending locking portion 3a at the upper end, and the lateral connecting member 3c provided on the magazine receiving frame 3 forms a quadrangle. Insert the magazine receiving plate 3e into the hole-shaped part 3d,
If the downward engaging eaves 3f is engaged with the quadrilateral hole-shaped portion 3d of the a-connecting member 3c , the other side that extends upward is increased.
Do not contact the vertical member 3b to prevent rotation.
The simple bookshelf 1 is completed.

[0010]

As described above, according to the present invention, since the main frame 2 which is the main part of the simple shelves 1 is composed of the steel pipes of the left and right side frames 2a and 2b made of steel pipe and the connecting pipe 2c, an expensive machine is used. can Ku production as it requires, and its assembly and disassembly is easier der
It The shape of the magazine receiving plate 3e and magazines receiving frame 3 attached simple bookshelves 1 to the main frame 2 is folded a simple wire or sheet material
Since it is constructed by bending and welding , molds and other expensive
It is easier to produce than when using various tools. Only
However, the assembly work can be done without using tools. Also,
Since degradation and is easy transportation also has effects such as easy.
