BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carry for carrying articles such as containers. More specifically, it is possible to stably stack a large number of carry, save space at the time of storage, and easily move and carry a large number of carry in a stacked state, The present invention relates to a carrying carrier having excellent transportability.

[0002]

2. Description of the Related Art Conventionally, a carrier equipped with four casters is a typical carrier used for transporting containers and the like, but a conventional transport carrier is used for loading and unloading containers and the like. Many proposals have been made with an emphasis on workability, ease of transportation, and stability when loading goods, and focus on the simplicity of storage of the carry itself, the economy of storage space, ease of transportation, etc. There were few improvements and improvement proposals. A so-called four-wheel adjustable type, in which all four casters are rotatable, and a two-wheel, two-wheel fixed type in which two of the four casters are rotatable. Many types are used. Each of these carries has advantages and disadvantages. In particular, the four-wheel adjustable type has the advantage of a small turning radius and excellent maneuverability, but has a problem of lack of straightness. In connection with the properties, there is a difficulty in stably stacking, and there is also a problem in the stacking workability.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a four-wheel adjustable carrying carrier that can easily and stably stack the carriers, and has a good storability. Another object of the present invention is to provide a four-wheel adjustable carrying carrier that can easily carry a multi-tiered product and has a good carrying property.

[0004]

According to the present invention, a carrying carrier comprising a quadrilateral support plate for loading articles and four casters provided on the lower surface side of four corners of the support plate. , The four casters are all swivel casters, and guide side plates extending upward are provided on four side surfaces of the support plate, and each caster is mounted on the loading surface side of the support plate. A caster stationary recess or opening is provided corresponding to the installation position of the caster, and among the caster stationary recesses or openings, caster guiding grooves are provided between those arranged along the straight traveling direction of the caster. Are extended, and two holes are formed at small intervals in the center of the support plate so as to form a carry grip, and a bottom of the support plate is provided at the bottom of the support plate. Fork insertion Groove, stacking possible carrying carry is provided, characterized in that it is formed toward the opposite side from the bottom portion side.

In the present invention, it is preferable that at least one of the casters is a caster with a stopper, and a cutout portion is formed in the guide side plate at a portion corresponding to a mounting position of the caster with the stopper.

[0006]

The carry of the present invention is of the four-wheel adjustable type described above, and it is important that all four casters are of the swivel-type. In this swivel-type caster, a wheel supporting member is rotatably attached to a lower surface of the article loading support plate, as described above.
A four-wheel adjustable carrying carrier using such a caster is excellent in mobility, but lacks straightness, and thus has a problem that the carrying work of the carrier itself is poor. In other words, since the two-wheel fixed two-wheel adjustable carry has a good straight running property, the workability of stacking work is particularly good, and various proposals have been made with respect to improvement of stability when stacked. In fact, such proposals have hardly been made with respect to a four-wheel adjustable carrying carrier.

However, according to the present invention, in such a four-wheel adjustable carrying carrier, the aforementioned guide side plate,
Caster stationary recess or opening, caster guide groove,
Provision of two holes for forming the carrier grip and the groove for inserting the fork of the automatic carrier makes it possible to easily stack the carry itself, and also extremely stable for a large number of carry stacked Can be held in

[0008] That is, the stacking work of the transport carry of the present invention is performed as follows. First, a finger is passed through two holes provided in the center of the article loading support plate to grasp a portion between the holes, and the carry is lifted up in a substantially horizontal state. In this state, slightly tilt the tip of the carry down,
When sliding on the support plate for loading goods of another carry, the wheels of the caster are guided along the caster guide groove,
The carrier enters the recess or opening for stationary placement, the carrier is fixed in position, and the stacking is performed. In the case of further stacking, the stacking may be performed on the carry stacked in the same manner as described above.

As is apparent from the above-described stacking operation, the two holes for forming the carry gripping portion at the center of the article stacking support plate are extremely important for performing the stacking operation quickly and efficiently. It is. That is, since such a hole is formed, the carry to be stacked can be easily lifted to a substantially horizontal state with one hand, and the other carry can easily slide on the article loading support plate. . For example, even if the carry can be easily lifted, the stacking operation cannot be performed quickly unless it is held in a substantially horizontal state. The caster guiding groove is for guiding the wheels of the caster into the caster stationary recess or opening, and the recess or opening is
This is for fixing the position of the wheel.

[0010] Further, the guide side plates provided on the four side surfaces,
It is intended to stably hold the stacked carry so that it does not fall from the support plate for loading goods of the lower carry, but at the same time, to carry out the carry stacking work quickly and smoothly is important. That is, in the carry of the present invention, since the casters are of a swivelable type, when the carry is slid on the support plate for loading the goods of another carry during stacking, the carry is meandered by the swivel of the casters, Wheel is not guided by the guide groove, and in an extreme case, it may jump out of the article loading support plate. However, by providing the guide side plate as described above, meandering of the carry is effectively suppressed, and the guiding of the wheels by the guiding grooves is performed smoothly.

The fork insertion groove of the automatic carrier provided at the bottom of the article loading support plate is for directly transporting a large number of stacked carriers by the automatic carrier easily. However, the formation of the groove makes it possible to make the guide side plate as high as possible, or to hold the wheels of the casters deeply in the caster fixing recesses or openings. That is, the fork insertion groove is extremely important for stably holding the stacked carriers.

For example, when transporting a large number of carry stacked by an automatic carrier, a fork of the carrier is inserted under the lowest one of the stacked carriers, and the carrier is stacked. The carried carry is lifted and carried. In this case, in the lowermost carry, a space is always formed between the wheel grounding surface and the bottom of the article loading support plate, so that no particular problem occurs in inserting the fork.
However, there is a problem when pulling out and using the stacked carry. That is, in this case, a fork is inserted and lifted between the lowermost carry and the upper carry among the stacked carry, and the lowermost carry is pulled out in this state. Therefore, in order to stably hold the stacked carriers, the guide side plate is made as high as possible, or the wheels of the caster are held deeply in the recesses or openings for stationary casters. The distance between the upper end of the carrier and the bottom of the support plate for carrying articles thereon is reduced by that much, so that sufficient space for inserting a fork cannot be formed. For this reason, the height of the guide side plate and the size of the caster stationary recess or opening are limited, and it has been difficult to stably hold the stacked carriers.

However, according to the present invention, since the fork insertion groove is formed at the bottom of the support plate for loading articles, the height of the guide side plate and the recess or opening for fixing the caster can be made as large as possible. Thus, it is possible to effectively draw out the stacked carry without impairing the holdability of the stacked carry.

Further, at least one of the swivel casters provided on the carry of the present invention is a caster with a stopper, for example, by locking the stopper of the stacked carry to stabilize the carry. can do. In addition, the work for stacking another carry on the carry can be easily performed, and the workability for stacking can be further improved.

In the case of the carry of the above-described embodiment, the guide side plate of the carry is partially formed at a portion corresponding to the stopper mounting position of the carry so that the locked state of the stoppers of the stacked carry can be easily determined from the outside. It preferably has a notched structure.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The carry of the present invention will be described based on a specific example shown in the accompanying drawings. In FIG. 1, which shows a perspective view of an example of the carry of the present invention, the carry has a support plate 1 for loading articles such as containers. The support plate 1 has a quadrilateral shape such as a square or a rectangle, and the upper surface thereof is an article loading surface. Of course, the support plate 1 does not need to be a strict quadrilateral, and for example, each of the four corners may have a curvature.

In the present invention, the casters 3 are respectively attached to the four corners on the bottom surface side of the support plate 1. In the present invention, the four casters 3 are all swivelable. Therefore, the carry can make a small turn and the mobility is extremely good. The swivel-type caster 3 has a wheel support member rotatably mounted on the lower surface of the support plate 1. Generally, the support member 3 is mounted on an extension of the rotation axis of the support member in the axial direction. A structure in which the rotation axis of the wheel is located at a slightly shifted position (hereinafter sometimes referred to as an eccentric caster) is used. That is,
In this eccentric caster, the wheel (axle) of the caster
By eccentrically outwardly with respect to the axial direction of the rotation axis of the support member, the carry is stabilized, and the work of loading articles on the carry can be performed stably. In addition, this eccentric caster is also suitable in terms of, for example, the storability of the stacked carry (in this regard,
See below). Further, it is preferable that at least one of the four casters 3 has a stopper.

In the present invention, four sides of the support plate 1
An upright guide plate 2 is provided, and a support plate 1 is provided.
It has a structure such that articles such as containers stacked thereon do not fall off the carry. When a caster with a stopper is used as the caster 3, a portion of the guide plate 2 corresponding to the position of the caster with a stopper 3 (the caster with a stopper in which no wheel is visible in FIG. 1) is cut off. A notch 5 is formed. Thus, the stopper can be locked in the stacked state, and the locked state of the stopper can be easily checked together with the position confirmation of the stacked carry.

On the upper surface of the support plate 1, that is, on the article loading surface side, caster fixing recesses 4 for fixing wheels of the casters are provided corresponding to the mounting positions of the casters 3. That is, the wheels of the stacked casters are fitted and held in the recesses 4. The recess 4 is provided with a hole 10 for draining water.

The materials constituting the support plate 1 and the guide side plate 2 are not particularly limited as long as they have strength and other properties capable of exhibiting the functions of these members. Any material such as a combination can be used, but the use of plastic is preferred because it is lightweight and easy to mold. When the support plate 1 is made of plastic, the guide side plate 2 and the support plate 1 can be integrally formed, or both can be separately manufactured and combined.

In the present invention, two openings 6 and 6 for gripping a carry are formed in the center of the support plate 1. That is, a finger can be passed through the opening 6 to grasp a portion between the openings 6, and the carry can be lifted with one hand in a substantially horizontal state with a good balance. Accordingly, the shape and size of the openings 6 and 6 are not particularly limited as long as a finger can be easily inserted, and the portion between the openings 6 and 6 is wide and long enough to be gripped by one hand. What is necessary is just to have a thing.

The caster guiding groove 7 is provided between the caster stationary recesses 4 which are arranged along the straight running direction of the caster (in FIG. 1, obliquely downward on the left side).
Is extending. That is, when stacking, the guiding grooves 7
Along with the wheels of the casters 3 are guided into the recesses 4.
On the bottom side of the support plate 1, a fork insertion groove 8 for a forklift or the like is provided.

The carry stacking operation shown in FIG. 1 is performed in the following manner. First of all, the caster of the lowermost carry 3
Lock the stopper. Next, the carry to be stacked is lifted while inserting the fingers into the above-mentioned openings 6 and 6 while maintaining a substantially horizontal state, and while slightly tilting the front wheel side (corresponding to the left side in FIG. 1) downward. Then, the carrier is driven on the support plate 1 as the lowermost layer. Thereby, the wheels of the casters, particularly the front wheels, are guided along the guide grooves 7,
It is fitted and held in the caster stationary recess 4. At the same time as the front wheel is held in the recess 4, the rear wheel lands and is held in the recess 4. In this case, since the guide plate 2 is provided in the present invention, the meandering of the carry is effectively prevented, the guide along the guide groove 7 of the wheel is performed smoothly, and the stacking work is performed quickly. Can be. When the eccentric casters described above are used, the front wheels are eccentric inward (rear wheel side) due to frictional force as they are guided along the guide grooves 7, while the rear wheels are inwardly moved by their own weight (front wheel side). ), The stacking is performed in a compact form, which is advantageous in terms of storability. After the completion of the above stacking, the stopper of the caster is locked, and further stacking is performed in the same manner.

The carry thus stacked is
The lowermost carry can be freely moved by releasing the caster lock. Alternatively, the fork can be inserted into the fork groove 8 and transported by a forklift or the like. Furthermore, the drawer of the stacked carry can be inserted by inserting a fork into the fork groove 8 of the carry located above the lowermost carry, lifting the carry above the carry, pulling out the lowermost carry, and using the carry. Can be provided.

In the above-described present invention, the depth of the caster fixing recess 4 and the height of the guide plate 2 are determined when the carry is stacked and the bottom of the support plate 1 of the stacked carry and the lower portion thereof. Can be set to such an extent that little gap is formed between the carry and the upper end of the guide plate 2. Usually, a fork is inserted into this gap, and the stacked carry is lifted to carry out the carry thereunder. In the present invention, the fork groove 8 is formed in the bottom of the support plate 1. It is not necessary to form such a gap, and as a result, the depth of the concave portion 4 and the height of the guide plate 2 can be set as large as possible, and the stacked carry can be stably held. You can do it. If the depth of the recess 4 and the height of the guide plate 2 are excessively increased, the stacked carry will be supported by the upper end of the guide plate 2 of the carry below it, and the wheels of the casters 3 will be supported. It is necessary to be careful because it will float.

In the carrying carrier of the present invention, various design changes can be made within a range in which the above-mentioned workability for stacking is not impaired. For example, the support plate 1 can be provided with a large opening, that is, a cutout portion, to reduce the weight of the carry. FIG. 2 is a plan view of such a carry, in which the support plate 1 is provided with four large openings 9.

The shape and size of the caster fixing recess 4 are not particularly limited as long as the wheels of the caster 3 can be properly set. For example, as shown in FIG. The shape may be a semi-elliptical shape (FIG. 3 (a)) or an inverted trapezoidal shape (FIG. 3 (b).) In any case, a drain hole is formed at the bottom of the shape. Further, as shown in FIG.
An opening may be used instead of the recess. The length of the opening should be slightly shorter than the diameter of the caster wheel, and its width should be slightly wider than the width of the caster wheel.

Further, in order to reinforce the strength of the support plate 1,
Ribs can be provided on the side and bottom of the support plate 1. FIG. 4 shows an example in which such reinforcing ribs are provided, and a reinforcing rib 11 is provided on the lower surface side (back surface side) of the support plate 1. In FIG. 4, reference numeral 12 denotes a caster fixing seat.

[0029]

According to the present invention, the work of stacking the four-wheel adjustable carry can be easily performed with one hand, and the stacked carry is stably and compactly held.
The transportability of the stacked carry is improved, and the carry storage space can be minimized, which is extremely advantageous in terms of storage and the like. Further, it is possible to easily pull out the carry from the stacked carry.
