Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf device suitable as a mounting shelf of a printer to which continuous paper (hereinafter, referred to as paper) such as computer continuous slip paper is supplied.

[Conventional technology]

Conventionally, in a shelf device on which a printer is mounted, since a paper is continuously supplied from the rear of the printer, in order to secure a space behind the printer, a shelf plate is suspended between left and right supports to form a shelf plate. It has a configuration that supports both left and right sides.

[Problems to be Solved by the Invention] However, according to this double-sided support method, the support structure is provided on both the left and right sides, so that the entire structure is inevitably complicated and is not preferable in terms of aesthetic appearance.

Further, it is convenient if the printer can be operated not only from the front but also from the side. However, in this case, there is an inconvenience in handling since the columns on both sides hinder the operation from the side.

On the other hand, it is conceivable to adopt a configuration in which the shelf board is supported by a single column, but there is a problem in the supply of paper, and there is a possibility of causing an adverse effect such as insufficient load supporting force.

In view of the above, according to the present invention, by adopting a structure in which the center of the rear end of the shelf is supported by one support, the structure can be simplified, the appearance can be improved, and the handling can be facilitated. It is an object of the present invention to provide a shelf device that can solve the problem in the case of employing a one-point support system called strength.

[Means for solving the problem]

The invention according to claim 1 includes a shelf plate and a column supporting a rear end central portion of the shelf plate. The shelf plate is provided on a lower surface of a shelf plate body provided with a paper feed hole at a rear portion. A shelf frame consisting of a frame material, a front frame material, and left and right horizontal frame materials is attached and configured.
The lower surface of the rear frame material is formed on a slope that is tapered downward from both left and right ends toward the center so that the vertical width of the rear frame material is largest at the center, and the vertical width of both ends of this rear frame material Have the same dimensions as the vertical width of the other frame members, and the central portion of the rear frame member is attached to the above-mentioned support.

According to a second aspect of the present invention, in the configuration of the first aspect, a reinforcing bar is provided between rear portions of the left and right horizontal frame members of the shelf frame, the reinforcing bar being in contact with the lower surface of at least one of the front and rear sides of the sheet feeding hole in the shelf body. is there.

According to a third aspect of the present invention, in the configuration of the first or second aspect, the shelf body has a shape that covers the entire upper surface and side surfaces of the shelf frame.

According to a fourth aspect of the present invention, in the configuration of any one of the first to third aspects, the shelf main body is made of a net plate material.

[Action]

In this way, by adopting a configuration in which the center of the rear end of the shelf is supported by a single column, the configuration is simplified, a simple aesthetic appearance is obtained, and the printer can be operated from both the left and right sides. It becomes convenient for handling.

In addition, since the shelf is formed by attaching a shelf frame as a load supporting member to the lower surface of the shelf main body, necessary load supporting strength can be sufficiently secured.

This point is particularly effective when the shelf board is formed of a net board material.

Further, since the paper feed hole is provided at the rear portion of the shelf body, continuous supply of paper to the printer can be performed without any trouble.

In addition, the rear frame member of the shelf frame has a shape having the largest vertical width at the center portion, which is an attachment point (a so-called hanging base) to the column, that is, a shape corresponding to the load distribution of the rear frame member. By setting the upper and lower widths of both ends of the material to be equal to the upper and lower widths of the other frame members, a sufficient load supporting force can be obtained with a minimum shelf frame material and a minimum shelf frame weight. Further, since only the vertical width of the central portion of the rear frame member is made larger than the others, the interval between the upper and lower shelves can be increased.

On the other hand, according to the second aspect of the present invention, the reinforcing bar is provided on the shelf frame in contact with the lower surface of at least one of the front and rear sides of the paper feeding hole, thereby effectively reinforcing the periphery of the paper feeding hole which is weak in strength. As a result, the load supporting strength of the shelf can be increased.

According to the third aspect of the present invention, since the shelf main body covers the entire upper surface and side surfaces of the shelf frame, the surface of the shelf plate becomes a smooth surface with no steps, which is convenient for cleaning and the like. further,
Since the shelf frame is concealed, it is aesthetically preferable.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

1. First Embodiment (See FIGS. 1 to 4) In FIG. 1, reference numeral 1 denotes a single support, reference numeral 2 denotes a base attached to a lower end of the support 1, and reference numerals 3 ... shelf boards.

As shown mainly in FIG. 2 and subsequent figures, each shelf 3 is provided on the lower surface of the shelf main body 4 with rear, front, left and right frame members 51, 52, and 5 respectively.
A shelf frame 5 formed by combining 3,54 in a square is attached and configured.
The central part of the rear frame member 51 in the shelf frame 5 is
(See FIGS. 3 and 4).

In this way, the center of the rear end of the shelf 3 is supported by the column 1 and the shelf load is mainly supported by the shelf frame 5.

Each of the frame members 51, 52, 53, and 54 of the shelf frame 5 is formed of a plate material, and ends of adjacent ones are rigidly welded.

In this case, the front frame member 52 and the left and right horizontal frame members 53, 54 are each formed in a normal strip shape having the same vertical width over the entire length, and the vertical width and the thickness of each are the same. I have.

On the other hand, since the rear frame member 51 is a portion to be attached to the column 1, the thickness of the rear frame member 51 is made larger than those of the other frame members 52, 53, 54 in order to have particularly high strength.

In addition, in view of the fact that a large load acts on the central portion (hanging source) 51a of the rear frame member 51, which is the actual attachment portion to the column 1, the vertical width of the central portion 51a is maximized.

Specifically, the upper and lower width dimensions of the left and right ends are changed to other frame members 52, 53,
It has the same dimensions as that of 54, and its lower surface is formed in a shape in which the central portion is flat and the left and right ends are inclined downward from the left and right ends toward the central portion.

In this way, the central portion 51a of the rear frame member 51 that is the suspension base, that is, the reaction force supporting portion, is given the highest strength, and the stress due to the shelf load is dispersed because the central portion 51a has a large area. Therefore, the load supporting force is high.

In addition, the left and right sides of the rear frame 51, or other frame
Compared to the case where the vertical width of 52, 53, 54 is the same as the vertical width of the rear frame material central portion 51a, the shelf frame material is minimally reduced,
In addition, the shelf board weight can be minimized and the gap (shelf board interval) between the shelf board and the lower shelf board can be increased.

On the other hand, the shelf main body 4 is formed by bending a side edge portion 42 in an arc shape below the entire peripheral portion of the main portion 41 having a shape substantially corresponding to the planar contour shape of the shelf frame 5 by a net plate material such as punched metal. The main portion 41 covers the upper surface of the shelf frame, and the side edge portion 42 covers and is fixed to the shelf frame 5 so as to cover the entire periphery of the side surface of the shelf frame.

In this way, by covering the entire shelf frame 5 with the shelf main body 4, the surface of the shelf is formed as a smooth surface with no steps, so that wiping cleaning or the like becomes easy.

The shelf main body 4 is provided with a long slot-shaped paper feed hole 43 on the left and right sides at the rear of the main portion 41, as shown by the phantom line in FIG. 3, for the printer 7 mounted on the shelf 3. This feed hole 43 from below
The paper 8 is continuously supplied through the.

In this way, even in this shelf device in which the space behind the shelf plate, which is a conventional paper supply path, is blocked by the support 1, the continuous supply of the paper 8 to the printer 7 can be performed without any trouble.

At the center of the rear end of the main portion 41, a notch 44 for escaping from the column 1 is provided. In FIG. 2, reference numerals 45... Denote corner members attached to each corner of the main body 4.

Second Embodiment (see FIG. 5) Only differences from the first embodiment will be described.

If the sheet feeding hole 43 is provided in the shelf main body 4, the strength near the sheet feeding hole 43 is inevitably weakened. In particular, when the shelf main body 4 is formed of a net plate material, this point poses a serious problem since the load supporting force of the main body 4 is originally weak.

Therefore, in the second embodiment, the left and right horizontal frame members in the shelf frame 5
The paper feed hole 4 in the main portion 41 of the shelf body 4
(3) A reinforcing bar 9 is provided in contact with the lower surface of the rear side, and the load applied to the vicinity of the paper feeding hole 43 is supported by the reinforcing bar 9 so that deformation and damage near the paper feeding hole of the main part 41 is prevented. ing. Incidentally, the reinforcing bar 9 may be provided so as to be in contact with the lower surface of the front side portion of the paper feeding hole 43, or may be provided on both front and rear sides of the paper feeding hole 43.

Further, the configuration of the present invention in which the shelf 3 is constituted by the shelf main body 4 and the shelf frame 5 is particularly effective when the shelf main body 4 is weak in strength. Although the case where the main body 4 is formed of a net plate material is taken as an example, the main body 4 may be formed of a normal metal plate (blind plate).

Also in this case, a high effect is exhibited in that the load supporting force of the shelf can be increased to obtain a stable supporting state.

〔The invention's effect〕

According to the present invention as described above, since the rear end central portion of the shelf board is configured to be supported by a single support, compared with a conventional shelf device that supports the left and right sides of the shelf by conventional two-sided support, Since the overall configuration is simplified, a simple aesthetic appearance is obtained, and the printer can be operated from both the left and right sides, it is convenient to handle the printer.

In addition, since the shelf is constructed by attaching a shelf frame as a main load supporting member to the lower surface of the shelf main body, a necessary load supporting strength can be sufficiently secured. This point is particularly effective in the invention of claim 4 in which the shelf main body is formed of a net plate material.

In addition, the rear frame member of the shelf frame has a shape having the largest vertical width at the center portion, which is an attachment point (a so-called hanging base) to the column, that is, a shape corresponding to the load distribution of the rear frame member. By setting the upper and lower widths of both ends of the material to be equal to the upper and lower widths of the other frame members, a sufficient load supporting force can be obtained with a minimum shelf frame material and a minimum shelf frame weight.

Accordingly, the material cost can be reduced, and the weight of the shelf is reduced, which is advantageous for assembly and transportation.

Further, since only the vertical width of the central portion of the rear frame member is made larger than the others, the interval between the upper and lower shelves can be increased.

Furthermore, because a paper feed hole is provided at the rear of the shelf body,
The continuous supply of paper to the printer can be performed without any trouble.

On the other hand, according to the invention of claim 2, the reinforcing frame provided in the shelf frame in contact with the lower surface of at least one side portion of the front and rear sides of the paper feed hole is provided. The load supporting strength of the plate can be increased.

Furthermore, according to the third aspect of the present invention, the shelf main body covers the entire top surface and the side surface of the shelf frame, and the shelf surface is a smooth surface with no steps, which is convenient for cleaning and the like. Further, since the shelf frame is concealed, it is aesthetically preferable.
