Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stock cart used for carrying and carrying luggage and for storing and storing luggage in a warehouse.

[0002]

2. Description of the Related Art A conventional stock cart is a dolly to which casters are attached, a pair of shelf frames attached to the front and rear parts of the dolly, and a shelf whose both ends are supported by the pair of shelf frames. It is composed of a board.

[0003]

[Problems to be Solved by the Invention] Conventional stockcar
Since the casters of the cart project from the base plate of the trolley, there is a drawback that it is difficult to operate by entwining with other stock carts during storage and storage. In addition, the shelves and shelves are likely to fall apart during storage and storage, which makes it difficult to organize them, and it takes time to set them during use.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
It is an object of the present invention to provide a stock cart that can be used easily without being entangled even when a dolly comes into contact with another dolly. Another object of the present invention is to provide a stock cart that can store and store movable shelf frames and shelf board members in a suspended state in a fixed shelf frame when not in use.

The above and other objects and novel characteristics of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a nestable frame having a tip portion having a width smaller than that of a rear end portion, and a tip supported on the upper portion of the frame. And a caster attached to both sides of the front end and the rear end of the frame so as not to project outward from the outer periphery of the base. And a shelf support bar having an inner width dimension larger than the width dimension of the base plate having a front end formed on an inclined surface and a lower end fixed to both sides of the rear end of the frame of the base. A fixed shelf frame having, and a movable shelf frame having a shelf plate support bar facing the fixed shelf frame detachably attached to the movable shelf frame support portion formed at the tip of the frame of the carriage, Both ends of the shelf support bar of the movable shelf frame and the shelf support bar of the fixed shelf frame are Constitute the door - Sutokkuka between shelf plate member that is detachably supported.

[0007]

With the stock cart constructed as described above, the caster does not protrude outward from the outer peripheral portion of the base plate, and the tip of the fixed portion of the fixed shelf frame with the frame is inclined. Since it is a surface, it does not get tangled even if it comes into contact.

[0019]

Different Embodiments of the Present Invention Next, different embodiments of the present invention shown in FIGS. 14 to 21 will be described. In the description of these different embodiments of the present invention, the same components as those of the first embodiment of the present invention will be designated by the same reference numerals and redundant description will be omitted.

The second embodiment of the present invention shown in FIGS. 14 to 16 is different from the first embodiment of the present invention in that the height of the fixed shelf frame 15 is the same as that of the fixed shelf frame 15 attached to the carriage 1. Since the movable shelf frame 23A is formed so as to have the height, the movable shelf frame 23A thus formed has a hook mounting bar 29.
Fixed shelf frame 15
It can be used as a stock cart 36A that can be attached and hung from the inside.

The third embodiment of the present invention shown in FIGS. 17 to 19 is mainly different from the second embodiment of the present invention in that the locking piece is attached to the shelf plate supporting bar 25 of the movable shelf frame 23B. 20,
20 to form a movable shelf frame 23B outside the fixed shelf frame 15,
The stock cart 36B configured in this way is that the shelf member 31 can be hung on the movable shelf frame 23B.
Even in this case, the same effect as that of the first embodiment of the present invention can be obtained.

The fourth embodiment of the present invention shown in FIGS. 20 and 21 is mainly different from the first embodiment of the present invention in that the base plate 7 is fixed to the frame 2A having a rectangular frame shape. Dolly 1
A and the stock cart 36C formed in this way in that the pair of shelf frames 23, 23 detachably attached to both ends of the carriage 1A are used, the first embodiment of the present invention The same effect as the example can be obtained.

[0023]

As is apparent from the above description, the following effects can be obtained in the present invention.

(1) A frame in which the front end has a smaller width dimension than the rear end and can be nested, a base plate supported on the upper portion of the frame so that the front end can be opened, and the frame can be opened. Of the frame of the trolley and casters mounted on both sides of the front end and both sides of the rear end of the trolley so as not to project outward from the outer periphery of the base plate. A fixed shelf frame having a shelf plate support bar having an inner width dimension larger than the width dimension of the base plate having a tip end portion formed on an inclined surface on both sides and fixed at a lower end portion; and a frame of the carriage. A movable shelf frame having a shelf plate support bar facing the fixed shelf frame detachably attached to a movable shelf frame support portion formed at the tip, a shelf plate support bar of the movable shelf frame, and the fixed shelf. It consists of a shelf board member whose both ends are detachably supported by the shelf board support bar of the frame. Therefore, the casters do not project outward from the outer periphery of the base plate of the trolley, and the lower end tip of the fixed shelf frame is an inclined surface, so even if it comes into contact with other stock carts, it will entangle. It is possible to use it comfortably by reliably blocking.

(2) According to the above (1), since the structure is simple, it can be manufactured at low cost.

(3) According to the above (1), the trolley portion can be nested, so that many can be stored in a small space in an aligned state.

(4) According to the second aspect, the same effects as (1) to (3) can be obtained, and the movable shelf frame and the shelf plate member can be stored and stored in a fixed shelf frame in a suspended state, so that they are scattered. It is possible to surely prevent problems such as getting sick and searching when used.
