DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a large number of dishes and trays in a stacked state and raises the dishes and trays so that the removal position is always constant even if the tableware or tray at the removal position is removed. The present invention relates to an open-lift tableware dispenser as described above.

[0002]

2. Description of the Related Art An example of a conventional open-lift type tableware dispenser will be described with reference to FIGS. First, a flat rectangular parallelepiped base 1 is provided with four casters 2.
Are mounted, and bumpers 3 are provided at the four corners of the base 1.
Is attached. A support 4 is erected on one side of the base 1. The support 4 includes a support frame 5 having a channel-like cross section with openings facing each other, and a cover plate 6 provided according to the thickness of the support frame 5. 7 are formed. Slits 8 are formed on both inner sides of the support 4 so as to be located at the boundary between the support frame 5 and the cover plate 6. A plate-shaped support member 9 is inserted into each of the slits 8, and a bearing 10 abutting on the inner surface of the support frame 5 is provided at an upper position inside the internal space 7 of the support member 9. In the lower position, a bearing 12 abutting on the other inner surface of the support frame 5 is provided on a support shaft 13. A spring hook angle 14 is provided below the support member 9, and a plurality of tension springs are provided between the spring hook angle 14 and a spring hook portion 15 provided above the support frame 5. 16 are spanned to form a spring lift structure 17.

[0003] A tableware holder 18 for holding tableware and trays is attached to the support member 9 above the base 1. In general, the tableware holder 1 is formed by stacking a plurality of racks accommodating a large number of tableware such as cups, or by stacking a large number of trays.
8 on top.

In such a configuration, the tableware holder 18
The tableware and trays held at the top are sequentially taken out from the uppermost one, whereby the support member 9 urged upward by the tension spring 16 to reduce the overall weight moves upward. This moving amount corresponds to the height of the removed tableware or tray, and the spring constant of the tension spring 16 is set so that the tableware and the like in the uppermost layer are always in a fixed position.

[0005]

Since the conventional open-lift type tableware dispenser has the above-described structure, there is a problem that the width B of the support frame 5 must be increased. That is, the bearings 10 and 12 and the tension springs 16 which are located opposite to each other are provided in the space inside the support frame 5, and in particular, the space inside the support frame 5 is limited due to structural restrictions. The dimensions are bearing 10,
12 and the radius of each of the bearings 10, 12
Is obtained by adding the diameter of the support shafts 11 and 13 and the diameter of the tension spring 16 disposed between the support shafts 11 and 13. For example, in an example of a product currently being produced, about It is 10 cm.

The fact that the width dimension B of the support frame 5 is large means that the movable tableware dispenser is dull and does not give a light impression. In addition, the effective use floor area on which dishes or trays can be placed is reduced with respect to the total occupied floor area.

Further, the conventional structure has another problem that the strength of the support frame 5 must be increased. That is, in the state shown in FIG. 8, the weight of the tableware acts on the support frame 5 as a force in the direction in which the bearings 10 and 12 open. Therefore, when the mechanical strength of the support frame 5 is weak, the support frame 5 is deformed as shown in FIG. This deformation impairs smoothness of movement and is not preferable. Therefore, in order to reduce the degree of deformation, the thickness of the support frame 5 is increased to increase its strength. For this reason, there is a disadvantage that the weight of the support frame 5 increases and the cost also increases.

[0008]

[0014]

FIG. 1 shows a first embodiment of the present invention.
4 through FIG. First, four casters 20 are attached to a flat rectangular parallelepiped flat base 19, and bumpers 21 are attached to four corners of the base 19. A support 22 is erected on one side of the base 19. This support 22
The support frame 24 includes two support frames 24 having channel-shaped cross sections with the opening portions 23 facing each other, and inner and outer cover plates 25 and 26 provided in accordance with the thickness of the support frames 24. An inner space 27 is formed by the cover plates 25 and 26. In addition, slits 28 are formed on both inner sides of the support 4 so as to be located at the boundary between the support frame 5 and the cover plate 25. A plate-like support member 29 is inserted into these slits 28, and an internal bearing 30 abutting on the inner surface of the support frame 24 is provided above the support member 29 at an upper position inside the internal space 27. Is provided. The internal bearing 30 is a relatively small-diameter ball bearing. Next, the support frame 24 is positioned below the support member 29.
An external bearing 32 is provided on the support shaft 33 so as to be in contact with the outer surface thereof. A spring hook 34 is provided below the support member 29, and a plurality of tension springs are provided between the spring hook 34 and a spring hook 35 provided above the support frame 24. 36 are spanned to form a spring lift structure 37.

Next, at the connecting portion between the lower end of the support 22 and the base 19, a support frame 24 of the support 22 is provided.
As a result of the reduction in the width dimension, there is a problem in strength.
For this reason, a reinforcing member 38 in the form of a scissor is fixed to an outer portion of a connecting portion between the lower end of the support 22 and the base 19.

A table holder 39 for holding tableware and trays is attached to the support member 29 above the base 19 to form a lift table 40. In general, racks for accommodating a large number of tableware such as cups are stacked on a plurality of stages, or a number of trays are stacked and placed on the tableware holder 39. In the present embodiment, it is assumed that a large number of trays 41 are placed.

In such a configuration, in use, a required number of trays 41 are placed on the tableware holder 39 in a superimposed manner. At this time, the spring constant of the tension spring 36 is set so that the total weight of the tray 41 placed on the tableware holder 39 is lowered by the height of the stacked layers. That is, no matter how many trays 41 are placed, the weight of the trays 41 acts to extend the tension springs 36, and the lift table 40 descends, and the amount of descending is equal to the height of the stacked trays 41. Since they match, the uppermost position of the overlapped trays 41 is always constant.
Further, although the width of the support 22 is small and the strength of the connecting portion with the base 19 is not strong, since the reinforcing member 38 is reinforced, the connection rigidity of the support 22 to the base 19 increases, There is no problem even if the overall weight of the tray 41 to be placed is large.

Next, when using the tray 41,
The trays 41 held by the tableware holder 39 are sequentially taken out from the uppermost one. The lift table 4 urged upward by the tension spring 36 to reduce the overall weight is thereby removed.
0 moves upward. This moving amount corresponds to the height of the removed tray 41, and the uppermost tray 41 is always located at the fixed position.

The weight of the tray 41 acting on the tableware holder 39 is in a cantilevered state by the support member 29.
The load in this cantilevered state is due to the internal bearing 30
4, the outer bearing 32 presses the outer wall of the support frame 24, and the tableware holder 38 is held so as not to be inclined. Moreover, since both the inner bearing 30 and the outer bearing 32 are small-diameter ball bearings, their rolling properties are good, and the lifting and lowering of the support member 29 is extremely smooth.

Further, since the support frames 24 are provided on both sides of the support body 22, and two support members 29 having a predetermined interval are inserted into each of the two slits 28,
It is held in a state where it does not fall laterally.

In particular, as compared with the conventional structure, the external bearing 32 extends outward from the inside of the support 22, so that the internal bearing 30 and the tension spring 36 are provided in the internal space 27 of the support 22. And the inner bearing 30 can be a small-diameter ball bearing, so that the width of the support frame 24 can be made very small. In one design example, the width of the support frame 24 can be reduced to 4 cm, which achieves the same function as that in the state where a width of 10 cm is conventionally required, thereby reducing the width by 6 cm. It was something that could be done. Further, even when the external bearing 32 is exposed, the external bearing 32 is located below the tableware holder 39, so that there is no obstacle in use. Further, since the inner bearing 30 and the outer bearing 32 are disposed so as to sandwich the common wall of the support frame 24, the support frame 2
Even if 4 is thin, the degree of its deformation is small.
The support frame 24 can be reduced in weight. In particular, when the inner bearing 30 and the outer bearing 32 are brought closer to the corner near the outer wall of the support frame 24, the degree of deformation of the support frame 24 is further reduced.

Next, a second embodiment of the present invention will be described with reference to FIG.
It will be described based on. In this embodiment, one base 1
9, two sets of support frames 24 are provided in parallel with each other, and a support member 29 is attached to the support frames 24 of each set, and two types of trays 41 and the like are independently placed. It is something that can be done. Therefore, items having different weights or different shapes can be placed on the independent tableware holder 39, respectively. In carrying out the present invention, they may be juxtaposed in a large number.
