Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a storage,
In particular, the present invention relates to a storage having an improved mounting structure for casters and the like.

[0002]

2. Description of the Related Art Generally, storages such as commercial refrigerators and refrigerators are supported by pedestals. For instance,
As shown in 1988 and JP-A-2000-81275, a male screw of a pedestal is screwed into a female screw formed at the bottom of the storage body to fix the pedestal.
Then, the height of each pedestal is adjusted by turning the adjusting screw at the tip of the pedestal in contact with the floor, and the horizontal level of the storage main body is maintained.

[0003] The female screw is formed by welding a nut to another thick sheet metal or by tapping on a highly rigid mounting plate without directly mounting the female screw on the bottom plate of the storage main body. The female screw is embedded in the heat-insulating foam of the storage body and cannot be removed from the outside.

[0004] A storage such as a commercial refrigerator or a refrigerator having such a pedestal structure is conventionally located near a cooking place, that is, in a kitchen room, so that the foodstuffs stored in the storage can be easily taken out and used. It was generally installed. Therefore, after being installed in a corner of the kitchen room, it hardly moved.

[0005]

In recent years, the method of providing food materials has changed, and a so-called take-out system has emerged in which customers can freely select food materials. In such a service form, a hotel bread is provided on the upper surface, and various ingredients such as salads, side dishes, and desserts are stored in the hotel bread.
A horizontal refrigerator-freezer provided to customers is used. And
Conventionally, a horizontal refrigerator-freezer used in a kitchen room is often diverted. In addition, layout changes in the store are frequently performed for the purpose of sales promotion, customer acquisition, and the like. In such a case, in addition to the weight of the storage main body, the weight of the stored food is added to the horizontal refrigerator-freezer,
The weight is 100 kg or more, and there is a problem that conventional pedestals cannot be easily moved.

[0006] Therefore, if the pedestal of the conventional storage is replaced with a caster, it can be easily moved by the wheels of the caster. However, when replacing the existing pedestal with casters on site, there are many cases where there is no caster that fits the female screw of the pedestal, and the mounting method may be different, so there is a problem that it can not be easily replaced. Was. In addition, casters of various specifications are designated according to the demands of the store, and must conform to various standards such as inch screws and fine screws. Generally, the bottom plate of the storage main body is usually thin, and there has been a problem that a nut cannot be directly welded or tapped on the bottom plate. Furthermore, when a flange-mounted caster that cannot be adjusted in height is designated, there is a problem that the height of the storage cannot be adjusted to other equipment. However, designing and manufacturing one storage body for each orderer for the mere installation of casters would be very labor-intensive and costly, and would not meet the delivery date.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and allows a non-genuine component of the storage, such as a caster, to be easily attached to the bottom surface of the storage in the market. It is an object of the present invention to provide a storage which can be adjusted freely.

[0008]

Means for Solving the Problems Claim 1 of the present invention provides:
In a storage unit in which a pedestal is attached to the bottom surface of the storage unit main body, one end is fixed to the bottom surface, and the other end is configured to be attachable to the bottom surface via an attachment plate fixed to a caster or the like. Therefore, the height of the casters and the like can be freely adjusted, and the casters and the like can be attached to an arbitrary position on the bottom surface of the storage main body.

According to a second aspect of the present invention, in a storage in which a pedestal is mounted on a bottom surface of the storage body, a first mounting plate fixed to the bottom surface and a second mounting plate fixed to a caster or the like.
The casters and the like are configured to be attachable to the bottom surface via a support plate of an elastic member, so that excessive force applied to the casters and the like does not reach the bottom surface of the storage. I have to.

According to a third aspect of the present invention, in a storage in which a pedestal is mounted on a bottom surface of a storage body, a first mounting plate fixed to the bottom surface and a second mounting plate fixed to a caster or the like.
The mounting plates are connected so that their relative positions can be moved, and the casters and the like can be attached to the bottom surface. I can do it.

FIG. 5 is an enlarged sectional view of a main part of a caster showing a second embodiment of the present invention, FIG. 6 is an exploded perspective view of the caster of FIG. 5, and FIG. 7 is a caster showing a third embodiment of the present invention. 8 is an exploded perspective view of the caster of FIG. 7.

Reference numeral 1 denotes a storage, which is a storage main body 3 which is open at the front and has a storage room 2 therein, a door 4 for closing the opening of the storage main body, and a machine for freezing or chilling the storage room 2. The room 5 is constituted. 6 is a caster, 7
Is a pedestal, and 8 is a female screw into which the pedestal is screwed.
The storage main body 3 includes an inner wall 9, an outer wall 10, and a bottom plate 11, and is filled with a heat insulating material 12, such as urethane, and is integrated. The top surface 13 of the storage main body 3 has a large opening 14, into which a plurality of hotel pans 15 are dropped, and the bottom is exposed to the storage room 2. A blower fan 16 and a suction port 17 are provided on the left side surface of the storage room 2, and form an air passage while communicating with the machine room 5. A cooling unit (not shown) is provided in the machine room 5 to cool the air circulating in the air passage and cool the storage room 2.

The hotel bread 15 is filled with ingredients such as salads, prepared dishes and desserts, and is indirectly cooled by the cool air in the storage room 2. Spare ingredients and the like are cooled and stored in the storage room 2, and the doors 4 are opened and closed to put in and out.

At the time of manufacture, the storage 1 is integrally foamed with a female screw 8 incorporated therein, and the pedestal 7 is packaged separately and shipped. At the site, the pedestal 7 is screwed into the bottom of the storage 1 and the foot is upright before use. According to the present invention, when there is a request from the store side to freely move the storage, when the casters 6 are added at the site, the convenience is most exhibited.

Based on the overall configuration described above, the first aspect of the present invention
FIG. 4 which is an embodiment of the present invention will be described. The caster 6 includes a wheel 18, a pedal 19, a cam 20 connected to the pedal, a brake 21 for braking the wheel, a spring 22 for releasing the brake, a caster body 23 for supporting the entire caster, and the caster body freely. It comprises a caster shaft 24 to be rotated, and caster bolts 25 which are vertically connected to the caster shaft. The caster bolt 25 usually has nuts 26 and 27 and a washer 28 fitted thereto.
Are attached to the caster bolt 25. Therefore, there is no need to purchase these nut parts newly on site.

In mounting the caster 6 on the bottom plate 11 of the storage main body 3, the mounting plate 29 has an inverted hat-shaped cross section.
Done through. A caster bolt 25 is passed through a hole (not shown) formed in the center of the mounting plate 29, and nuts 26, 2
The caster bolt 25 is fixed with 7 and the washer 28. At this time, by adjusting the extension H of the caster bolt 25, the height of the caster 6 can be changed, and thus the total height of the storage can be adjusted. Thus,
After the caster 6 is firmly fixed to the mounting plate 29, the flange of the mounting plate 29 is applied to an arbitrary position of the bottom plate 11, and the tapping screw 30 is screwed through holes (not shown) formed at four corners of the flange. 29 is fixed to the bottom plate 11. The bottom plate 11 of the storage main body 3 is generally a thin steel plate and has a thickness of about 0.6 mm, so that the tapping screw can be screwed in without difficulty.

As shown in FIG. 2, if four mounting plates 29 are attached to arbitrary positions of the bottom plate 11 and the casters 6 are provided, the storage 1 can be moved freely. At this time,
Adjusting the tip screw portion of the pedestal 7 so that the pedestal 7 does not touch the ground first, shorten the pedestal 7 or adjust the extension H of the caster bolt 25 in FIG. Raise the legs 7. Also, the four legs 7 may be left attached,
As shown in FIG. 1 and FIG. 2, only the front two may be left,
Or you may remove all.

When the storage is stopped so as not to move, the pedal 19 of the caster 6 is depressed. Then, cam 2
0 rotates, and the brake 21 is pressed against the wheel 18 to brake the wheel 18. When the pedal 19 is returned to the original position, the cam 20 separates from the brake 21, the brake 21 separates from the wheel 18 by the restoring force of the spring 22, and the braking is released.

As described above, according to the first embodiment of the present invention, since the caster is mounted via the mounting plate, the caster can be mounted at an arbitrary position on the bottom surface of the storage main body regardless of the size of the bolt of the caster. And the height of the casters can be freely adjusted.

Next, a second embodiment of the present invention will be described with reference to FIGS.
6 will be described. The structure of the casters 6 is the same as that of the first embodiment, and the numbers assigned are the same and the names are the same, so the description of the casters 6 is omitted. A mounting plate 29, which is a first mounting plate, is fixed to the bottom plate 11, and has a box-shaped cross section in an inverted hat shape. The base 32 as the second mounting plate
Is a flat plate integrated with the nut 27 at the welding portion 31. The base 32 is housed inside the mounting plate 29, and its end face is held down by flanges of support plates 33 and 34 made of an elastic material. The support plates 33 and 34 are firmly fixed to the side wall of the mounting plate 29 by tightening the screw 35, and press the base 32 from above with its own flange.

In such a configuration, the height of the caster is adjusted by adjusting the extension H of the caster bolt 25. The caster bolt 25 is firmly fixed by the nut 26, the washer 28, and the base 32. Now, it is assumed that an excessive force is applied to the caster 6.
For example, this corresponds to a case in which the storage body is dragged while the brake 21 is being applied while the pedal 19 is being depressed, or a case where the wheel 18 is strongly moved in a state of being restrained in the depression. In this case, a large bending moment is applied to the caster bolt 25, and a force to tilt obliquely acts. Then, the base 32 integrated with the nut 27 tends to tilt. At this time, the flanges of the support plates 33 and 34 made of an elastic material are bent, and the inclination of the base 32 is absorbed, so that the mounting plate 2
9 prevents deformation. In this manner, the first mounting plate 29 fixed to the bottom surface of the storage body and the base 32 of the second mounting plate fixed to the casters are elastically connected by the support plates 33 and 34. There is an effect that the bending moment is not applied to the thin bottom plate 11 and an excessive force is not transmitted to the thin bottom plate 11, so that the fastening of the tapping screw 30 is not loosened and the bottom plate 11 itself is not deformed.

Next, a third embodiment of the present invention will be described with reference to FIGS. The lower structure of the caster 6 is the same as that of the first and second embodiments, but the mounting method of the upper part of the caster is different. The caster 6 has a caster flange 36 as a mounting surface instead of the caster bolt. The mounting plate 29 is a first mounting plate equivalent to the first and second embodiments, and is fixed to the bottom plate 11 by tapping screws 30. The slider 38 is a second mounting plate, and the caster flange 36 is fixed by a fixing screw 37. The slider 38 has a U-shape. The inner diameter of the U-shape is slightly larger than the outer diameter of the mounting plate 29, and is designed so that it can move up and down when the slider 38 is put on the mounting plate 29. Then, four long holes 39 are formed on the side surface of the slider 38, and four female screws 40 are formed on the side surface of one mounting plate 29 at positions corresponding to the long holes 39.

A method of adjusting the height of the caster 6 with such a configuration will be described. First, the casters 6 are fixed in advance with the fixing screws 37.
After being fixed to the slider 38 with, it is put on the mounting plate 29. Then, the elongation allowance H is determined by passing the adjusting screw 41 through the long hole 39 and firmly fixed. In this state, the mounting plate 2
9 is fixed to the bottom plate 11 of the storage with tapping screws 30.
Even in the case of such a flange-type caster, the first mounting plate 29 fixed to the bottom surface of the storage and the slider 38 of the second mounting plate moving the mounting plate vertically move relative to each other. By adjusting the position with the long holes 39, the height of the casters can be changed.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and is applicable not only to a commercial horizontal refrigerator-freezer, but also to a constant-temperature high-humidity cabinet, cabinets and furniture. it can. Further, instead of the casters, the present invention can be applied to a pedestal of a reduced diameter screw. Further, the cross section of the mounting plate 29 does not necessarily have to be a hat type, but may be an I type, a T type,
The shape may be Z-shaped or U-shaped, and the connection between the parts may be rivets instead of screws.

[0025]

As described above, according to the first aspect of the present invention, since the casters and the like are mounted via the mounting plate, the casters can be mounted at any position on the bottom surface of the storage main body regardless of the size of the bolts of the casters and the like. And the like, and the height of the casters and the like can be freely adjusted.

According to the second aspect of the present invention, since the first mounting plate fixed to the bottom surface of the storage body and the second mounting plate fixed to the casters and the like are elastically connected, the bending moment up to the thin bottom plate. The effect is that the excessive force is not transmitted, the tapping screws are not loosened, and the bottom plate itself is not deformed.

According to the third aspect of the present invention, even in the case of a flange type caster or the like, the first mounting plate fixed to the bottom surface of the storage body, and the second mounting plate moving the mounting plate vertically. Can be adjusted by the elongated holes 39, so that the height of the casters and the like can be adjusted.
