Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shelf, and more particularly to an improvement in the structure of a shelf body supported by columns.

[Background technology and its problems]

In recent years, steel shelves have been widely used in schools, hospital kitchens, etc. from the viewpoint of hygiene and durability. In this type of shelf, the height of the shelf body on which tableware or cooking utensils are placed can be adjusted with respect to the pillars, so that the shelf body can be positioned at the optimal height and placed. There are some that aim to make effective use of the area. For example, Japanese Patent Publication No. 50-25372 discloses a shelf in which the height of the shelf body is adjustable. This product consists of a cylindrical column in which grooves are formed in the circumferential direction at predetermined pitches in the axial direction, a two-piece intermediate member attached to the column, and a pusher that is tapered and fitted to the intermediate member. It is composed of a shelf body equipped with a shelf body. This shelf body adjusts the height position of the shelf body by unfitting the bushing from the intermediate member, shifting the mounting position of the intermediate member, and fitting the bushing at the newly positioned position. However, the intermediate member is a two-piece type that combines two approximately semi-cylindrical members, and requires the work of butting the two members together when attaching it to the pillar, so it can be done with one hand. Due to the operation, so-called one-touch installation was impossible. Moreover, the shelf main body disclosed in the above publication has an outer frame made up of two parallel steel wires with a substantially circular cross section and steel wires extending in a corrugated manner to connect these steel wires. This had the disadvantage of complicating the structure of the frame. In addition, the steel wire that is installed between the inner sides of the outer frame is fixed by welding with its end intersecting one of the steel wires that constitute the outer frame. The welded portion is visible on the outside as it is, causing a loss of appearance. Moreover, depending on the quality of the welding, it also has the disadvantage of extremely poor texture.

[Purpose of the invention]

The object of the present invention is to have a simple structure, and
To provide a shelf having excellent strength and appearance.

[Means and actions for solving problems]

The present invention provides a plurality of struts having grooves formed in the circumferential direction at predetermined pitches, intermediate members removably attached to predetermined positions of these struts, and a structure supported by the struts via these intermediate members. In the shelf, the intermediate member has a peripheral wall that is open at both ends, and a slit is formed in the axial direction of the peripheral wall, and one end of the slit is formed in a notch that gradually widens. and a locking portion that engages with a predetermined position of the support column is formed along the circumferential direction on the inner peripheral surface of the peripheral wall, and further, at least one weakened portion extending in the axial direction is formed in the peripheral wall portion. The shelf body is connected to engagement members that are fitably provided to each of the intermediate members, and is connected so as to span over each of these engagement members to define a predetermined shape. This device is characterized by being composed of an outer frame made of a plate-like member in which a large number of shaped holes are formed, and a receiving portion forming member disposed between the inner sides of the outer frame.

In short, the present invention makes it possible to easily attach the intermediate member to the support and adjust its attachment position, and also improves the strength of the shelf body by forming the outer frame from a plate-like member, and also improves the appearance. The purpose is to achieve the above objective by improving the texture.

and four shelf bodies 12 which are supported by these pillars 11 and formed in the same shape.

The support column 11 is provided in a hollow elongated cylindrical shape made of steel or the like (fourth column).
(see figure), grooves 13 are formed in the circumferential direction at predetermined pitches in the axial direction.

At the outer periphery of the support column 11, the shelf body 12
As shown in Figure 4, the part supporting the
An intermediate member 14 is removably fitted. This intermediate member 14 is made of vinyl chloride resin, AS resin,
It is molded from a flexible synthetic resin material selected from ABS resin, polyethylene, polypropylene, polycarbonate, etc., and its inner diameter is approximately the same as the outer diameter of the support column 11, and the outer diameter slightly expands downward. It is formed into an open tapered shape, and its overall shape is a short cylinder. Also,
As shown in FIG. 5, a part of the peripheral wall 15 of the intermediate member 14 is formed with a slit 16 that reaches both ends in the vertical direction. It is formed in a skirt-like notch 17. Also,
As shown in FIG. 6, weakened portions 15A are provided at two locations on the inner surface of the peripheral wall 15 along the vertical direction of the peripheral wall 15, respectively. These weakened portions 15A are formed by thinning the peripheral wall 15 so that the planar shape is substantially arcuate, and as a result, the intermediate member 14 allows the notch portion 17 to be attached to the support 11 as shown in FIG. When pressed along the slit 16 while in contact with an arbitrary position, the slit 1
The peripheral wall 15 near 6 is expanded in the direction of expansion from the weakened portion 15A, is forcibly fitted to the support column 11, and can be removed by pulling in the opposite direction. Further, a groove 13 formed in the support column 11 is provided on the inner periphery of the upper end of the peripheral wall 15 of the intermediate member 14.
A protrusion 18 that fits into the groove 13 is provided, and when the protrusion 18 is fitted into the groove 13, the intermediate member 1
4 cannot be freely moved up and down on the support column 11.

The shelf main body 12, as shown in FIG.
An outer frame 20 provided so that the planar shape defines a substantially rectangular shape, and bushes 21 as engagement members provided at the four corners of this outer frame 20,
It is constituted by steel wires 22 arranged vertically and horizontally as receiving part forming members extending inside the outer frame 20.

The outer frame 20 includes a pair of plate-like members 20A that extend relatively long and in parallel, and these plate-like members 2.
A pair of plate-like members 20B connect both ends of 0A via the bush 21. These plate-like members 20A and 20B have the same cross-sectional shape, and are shown in FIGS. 4 and 8.
As shown in the figure, a flat plate part 23 in which circular holes 25 are bored at predetermined intervals in the longitudinal direction;
In the figure, the edge 24 is formed along the longitudinal direction of the flat plate part 23 at both upper and lower end edges. These edges 24 are formed so as to have a circular cross-sectional shape, so that the outer frame 2
The entire 0 gives a smooth texture.

The bush 21 allows the support 11 to support the shelf main body 12 which is tapered fitted to the outer peripheral surface of the intermediate member 14, and is formed into a substantially cylindrical shape. The inner circumferential surface of this bush 21 is formed into a tapered surface corresponding to the outer circumferential tapered surface of the intermediate member 14, so that the bush 21 is fitted into the intermediate member 14, and as a result, the shelf body 12 is supported by the support column 11. It is becoming more and more common.

As shown in FIG. 1, the steel wire 22 includes a large number of short members 22A that are arranged in parallel to connect the long plate members 20A;
The short plate-like members 2 are orthogonal to these short members 22A and are welded to each other at alternating points.
It is composed of a pair of long members 22B extending in parallel so as to connect the wires 0B, and these steel wires 22 form a receiving part for cooking utensils and the like. The steel wires 22 are respectively connected to the upper portions between the circular holes 25 in the flat plate portion 23 (see FIG. 4). At this time, the end surface 28 of the steel wire 22 to be connected is
It abuts against the flat plate part 23 at right angles and is fixed by welding at the corner part 28B. Further, a reinforcing plate-like member 26 is stretched between the plate-like members 20B at an axially intermediate portion of the steel wire 22A, and this reinforcing plate-like member 26 is connected to the plate-like member 20A of the outer frame 20. It is made of a member similar to that without edges. Note that the reference numeral 27 in the figure is a height adjustment screw screwed into the lower end of the support column 11.

Next, the manufacturing process of the shelf according to this embodiment will be explained.

To assemble the shelf body 12, first, the plate members 20A and 20B are set in relative positions so as to define a rectangle. Next, the plate members 20A and 20
Bushes 21 are interposed at both ends of B, that is, at the corners of the rectangle, and in this state they are connected and fixed by welding or the like to form the outer frame 20. The outer frame 20 formed in this manner is placed, for example, on a floor surface. Here, the steel wires 22 are arranged one by one between the plate-like members 20A, and the steel wires 22 and the flat plate portions 23 of the plate-like members 20A are connected by welding. At this time, the ends of the steel wires 22 are locked to the bases of the edges 24 of the plate-shaped member 20A, and are naturally set in a state exactly opposite to that shown in FIG. is extremely easy to perform. After the steel wires 22 are welded and connected in this way, the reinforcing plate member 26 is placed between the short plate members 20B, and the plate members 20B and the reinforcing member 26 are welded together.

On the other hand, each of the pillars 1 has one intermediate member 14.
the intermediate member 1 at a predetermined position.
The protrusions 18 of No. 4 are fitted into the grooves 13 of the support columns 11. When fitting the intermediate member 14 to the column 11, the notch 17 of the intermediate member 14 is brought into contact with the outer peripheral surface of the column 11 as shown in FIG. While pressing it, make it stand up in the direction of the arrow in the figure. Then, the notch 17 is expanded along the outer circumferential shape of the support 11, the slit 16 is also gradually expanded, and by further pushing the intermediate member 14 into the support 11, the fitting is completed. At this time, the weakened portion 15 is attached to the peripheral wall 15.
Since A is formed, the peripheral wall 15 can be expanded without difficulty, and there is no risk of damage. Furthermore, pillar 1
When a plurality of shelf bodies 12 are to be locked to the shelf body 1, only the lowermost intermediate member is fitted.

In this way, when the preparation for assembling the shelf main body 12 and the pillars 11 is completed, the pillars 11 are inserted into the bushes 21, and the bushes 21 are attached to the pillars 1.
1 until the intermediate member 14 is fitted. In this state, the support column 11 can be erected on the floor, and after fitting the intermediate member 14 to the erected support column 11 in the same way, each shelf body 12 is inserted from above via the bush 21. Then, a multi-stage shelf as shown in FIG. 2 can be obtained.

When adjusting the height of the shelf body 12 after assembly is completed, lift the shelf body 12 and remove each bush 21 from the intermediate member 14.
Either remove the intermediate member 14 partway from the support 11 and slide it along the support 11 to the desired position in this state, or remove the intermediate member 14 completely from the support 11 and place the removed intermediate member 14 on the support 11. It is fitted from the notch 17 at the desired height position as described above. By fitting the bush 21 onto the intermediate member 14 whose height has been adjusted in this manner, the height position of the shelf body 12 can be adjusted.

According to this embodiment, the following effects can be obtained.

That is, each of the plate-like members 20A and 20B constituting the outer frame 20 is formed by a flat plate portion 23 and an edge 24 having a substantially circular cross section.
Steel wire 22 installed inside 20B
The outer frame 20
The outer surface of the product can be made smooth, so that the welded part does not appear on the outer surface as in the conventional method, and it feels good to the touch and does not spoil the appearance at all. Further, since the edge 24 of the plate-like members 20A, 20B has a circular cross section, the edge 2
4, the steel wire 22 can be locked to the continuous portion with the flat plate part 23, which is the base of the outer frame 20, so there is no need to provide any support when welding the steel wire 22 to the outer frame 20, and the locked state can be maintained. Welding can be performed extremely easily and workability can be improved.

Furthermore, since the plate-like members 20A and 20B can be integrally formed by extrusion molding, press molding, etc., they are easy to form and have superior strength compared to conventional wire-made members. be able to. Further, since the flat plate portion 23 is configured to have circular holes 25 bored at predetermined intervals along the longitudinal direction, ventilation of the entire shelf can be maintained.
Not only is it hygienic as it can improve drainage as a kitchen shelf, but the shape of the holes can be set according to the customer's requests. In this case, if the customer is a company, it is conceivable to use a hole shaped like a company sign.

Furthermore, since the intermediate member 14 can be removably fitted to any position of the support column 11 by providing a slit 16 and a skirt portion 17 in the peripheral wall 15, the attachment position of the intermediate member 14 to the support column 11 can be changed. By changing the height of the shelf body 12, the height of the shelf body 12 can be adjusted, and in the case of a multi-level shelf, by appropriately changing the dimensions between each level,
Space for placing cooking utensils, etc. can be used effectively without waste. In addition, since the intermediate member 14 has the weakened portion 15A, the slit 16, and the skirt-like notch 17, it can be forcibly deformed without difficulty, and can be easily attached to and detached from the support column 11, as well as being integrally molded with a mold. It can be manufactured at low cost.

Note that in this embodiment, the outer frame 20
The plate-like members 20A and 20B were composed of a flat plate part 23 and an edge 24, and the edge was formed to have a circular cross-sectional shape.
The shape is not limited to this, and for example, a plate-like member 20 as shown in FIG. 9 may be used. The upper edge 3 of this plate-like member 20
0 extends outward from the upper end of the flat plate part 23 in a semicircular arc shape, and its tip is formed to gently point inward and diagonally downward, while the lower edge 31 extends outward from the lower end of the flat plate part 23. It extends toward the direction in a semicircular arc shape, and its tip is cut off in the same plane as the inner surface of the flat plate portion 23. Further, this plate member 20 is formed by forming a plate material with holes punched by press molding, or by press working entirely. When such a plate member 20 is used, the steel wire 22 and the plate member 20 are spot welded from two directions indicated by arrows A in FIG.
Therefore, there is no need to perform welding work between the steel wire 22 and the plate member 20 in a narrow area, improving work efficiency, and reducing the length of the end of the steel wire 22. Since it is somewhat short and does not need to come into contact with the plate-shaped member 20, and there is no need to be so concerned about variations in the dimensions of the steel wire 22, work efficiency can also be improved from this point of view. Moreover, since the lower edge 31 of this plate member 23 is cut out in the same plane as the inner surface of the flat plate part 23, the steel wire 2
2 can be easily interposed between the plate-like members 20A, and there is also the added effect that there is no risk of dust etc. accumulating inside the edges 31.

Note that the plate members 20A and 20B described above do not necessarily require the edge 24, and may be a simple flat plate or a so-called punching metal. moreover,
Although the shelf main body 12 has a rectangular planar shape, it may have a polygonal shape other than a rectangular shape, a circular shape, or other shapes. However, a rectangular shape is advantageous in that steel wires, plate-shaped members, etc. having uniform length can be used. In addition, although the receiving portion forming member is made of steel wire, it is also possible to use copper wire, aluminum wire, or wire made of other metal materials.
Additionally, a material in which a predetermined metal material is covered with plastic can also be used. Furthermore, the arrangement of the steel wires is not limited to a lattice-like arrangement, as long as it has enough strength to allow tableware and the like to be placed thereon.

〔Effect of the invention〕

According to the present invention as described above, the structure is simple;
It is possible to provide a shelf that is excellent in strength and has a good appearance.
