Abstract

PURPOSE:To eliminate a trouble of wrongly operating a downward cut-out window when a drawer is drawn out in a portable type wagon constituted to form a single opening when the downward cut-out window formed in a ceiling plate is opposed to an upward cut-out window formed in the uppermost drawer. CONSTITUTION:An operating piece 8 united with the uppermost drawer 2 to be manually operated from the lower surface side is disposed between a downward cut-out window 77 and upward cut-out window 22 in an opening section. Even if a hand is put on the uppermost drawer 2 to operate it from the lower surface side according to the existing concept, the uppermost drawer 2 can surely be drawn out so long as the hand is set to be put more easily on the operating piece 8 than on the downward cut-out window 77. Thus, the problem of wrong operations for the uppermost drawer 2 frequently operated can surely be eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable wagon having a plurality of drawers.

[0002]

2. Description of the Related Art Recently, a portable wagon which can be used as a sleeve of a desk or a side desk has been developed. However, in the conventional one, the wagon body provided with casters is provided with a plurality of drawers, and the whole wagon can be moved to a desired position by applying an external force.

However, in the conventional case, the end plate of each drawer is provided with an opening that functions as a handle, but the wagon body has no place to reach. Therefore, although there is no problem in pressing and moving, it is inconvenient when pulled out from under the desk. In addition, the top drawer is often used to store small items such as writing instruments, so it is desirable to make the top drawer thin and the other drawers thick to improve practicality. However, if the uppermost drawer is provided with an opening similar to the drawers of other tiers as in the past, the uppermost drawer cannot be made thin and the degree of freedom in design is impaired. There are drawbacks.

Therefore, the inventor of the present invention has filed Japanese Patent Application No. 1-4392.
In JP-A-0, the casters are attached to the bottom surface of a wagon body having a plurality of drawers, while the top plate is disposed on the top surface of the wagon body, and the front end surface of the top plate is provided with a hand from the bottom surface side. A downward cutout window that can be hung on is formed, and an upper cutout window that can be reached from the top side is formed on the upper edge of the uppermost drawer end plate, and the drawer is closed. In this case, we have developed a structure in which the downward cut window and the upward cut window can face each other to form a single opening.

According to this structure, the whole wagon can be moved to the front by hooking the finger inserted into the opening to the downward cutout of the top plate from the lower surface side and pulling it.
The uppermost drawer can be pulled out by hooking the finger inserted in the opening into the upward cutout of the drawer from the upper surface side and pulling. Therefore, by forming the opening portion in a divided manner, the effect of improving the operability in transporting the entire wagon, and since it is sufficient to form one half of the opening portion in the uppermost drawer The effect is that flattening is possible.

[0006]

However, in such a wagon, the uppermost drawer must be operated with the hand from the upper surface side. However, we customarily recognize that the drawer is to be reached from the bottom side. For this reason, when the wagon is used, there are many cases in which the drawer is operated but the wagon body is being operated, and since the operation force at that time is not so large, there is no problem that the wagon body moves. However, there is an inconvenience that it is necessary to hold the hand and hang it again from the upper surface side to perform the operation again.

An object of the present invention is to eliminate such an erroneous operation.

[0008]

The present invention adopts the following constitution in order to achieve the above object.

That is, in the wagon according to the present invention, while the casters are attached to the bottom surface of the wagon body having a plurality of drawers, the top plate is disposed on the upper surface of the wagon body.
On the front end face of the top plate, a downward cutout window that can be reached from the bottom side is formed, and at the top edge of the top end drawer end plate, you can reach from the top side. A transportable wagon configured such that a cutout window is formed, and when the drawer is closed, the downward cutout window and the upward cutout window face each other to form a single opening. An operating piece that is integral with the drawer and that can be reached with a hand from the lower surface side is disposed between the notched windows in the section.

In order to more appropriately eliminate the erroneous operation with respect to the uppermost drawer, it is desirable that the operation piece is disposed at a portion which is offset toward the downward cutout window side with respect to the center of the opening.

In order to prevent the operation of the downward cutout window from being obstructed by the presence of the operation piece, the operation piece is a movable one hinged to the rear edge of the drawer and the downward cutout window of the top plate. It is desirable to be configured to perform a downward pivoting and retracting operation by the pressing force when the hand hung on the hand contacts.

In this case, in order to reduce the number of parts,
It is convenient for the operating piece to be hinged to the drawer via a resin hinge.

As another mode for preventing the operation of the downward cutout window from being obstructed by the presence of the operation piece, the operation piece is a movable one having both left and right edges attached to the drawer, and the top plate. An example is one that is configured to perform a curved retracting operation downward by the pressing force when the hand hung on the downward cutout window comes into contact.

When the operation piece is movable, it is desirable to attach a stopper to the operation piece to prohibit the upward turning and retracting operation or the bending retracting operation.

Further, the operation piece may be fixed to the drawer. In this case, in order to ensure the operability of the downward cutout window, the operation piece has a cutout in the center, and it is possible to insert the cutout to reach the downward cutout window of the top plate. It is preferably configured so that it can.

[0016]

With this structure, the whole wagon can be moved to the front by hooking the finger inserted into the opening in the downward cutout of the top plate from the lower surface side and pulling it.
The uppermost drawer can be pulled out by hooking the finger inserted into the opening into the upward cutout of the drawer from the upper surface side and pulling. Further, the uppermost drawer can be pulled out even when the finger inserted into the opening is hooked on the drawer operation piece from the lower surface side and pulled.

Therefore, in the wagon of the present invention, even if the operator tries to operate the uppermost drawer from the conventional concept, he or she may touch the operation piece from the lower side, and the operation piece may be placed on the operation piece rather than the downward cutout window. If you set it to be easy,
It is possible to reliably pull out the uppermost drawer.

A downward cutout window 77 is formed on the front end surface 7a of the top plate 7 so that a hand can be reached from the lower surface side, and the upper edge of the end plate 21 of the uppermost drawer 2 can be touched from the upper surface side. Form an upward cutout window 22 that can be hung,
When the drawer 2 is closed, the downward cutout window 77 and the upward cutout window 22 face each other to form a single opening 23. Specifically, the downward cutout window 77 is formed by cutting out the central portion of the lower edge of the front plate portion 73 of the top plate 7, and the rear side of the downward cutout window 77 is surrounded by a partition wall 78. On the other hand, the end plate 21 of the uppermost drawer 2 includes a back plate portion 25 fixed to the front end of the body plate 24 by welding, a front plate portion 26 attached to the front surface of the back plate portion 25, and the front plate portion 26. Housing 2 made of synthetic resin, which is arranged between the back plate 25 and the back plate 25.
7, the casing 27 is exposed to the outside from a notch 26a formed at the center of the upper edge of the front plate 26 to form the upward notch window 22. There is. The housing 27 is opened at the front surface and the upper surface, and has a ridge 27b formed on the front edge of the bottom wall 27a thereof, which makes it easy to reach from the upper surface side. And this housing 2
By attaching projecting mounting portions 27g having screw holes 27f at both left and right ends of 7, screw 27h penetrating the back plate portion 25 is screwed into the screw holes 27f of the mounting portion 27g and tightened. The housing 27 is fixed to the back plate portion 25. The horizontal dimension of the upward cutout portion 22 is set to be the same as the horizontal dimension of the downward cutout portion 77,
When the drawer 2 is closed, these downward cutouts 77
And the upward cutout 22 face each other to form a substantially rectangular opening 23. And this opening 23
Is substantially the same as the openings 33 and 43 for the handles provided in the end plates 31 and 41 of the other drawers 3 and 4.

In this structure, in this embodiment, the uppermost drawer 2 is integrated between the notched windows 22 and 77 in the opening 23, and a hand can be reached from the lower surface side. An operation piece 8 is provided. More specifically, the operation piece 8 is, as shown in FIGS.
7 has a plane dimension to be accommodated in the opening edge, and a step portion 83 is formed between the base end portion 81 and the tip end portion 82, and the step portion 83 can be touched from the lower surface side. Is done. On the other hand, downward claws 84 that are integral with the operation piece 8 are hung at three rear edges of the base end 81, and the downward claws 84 are formed at the boundary between the downward claws 84 and the base end 81. Resin hinge 84a that is easily elastically deformed in the direction in which the attachment angle of the claw 84 is changed
Is formed. A cut-and-raised piece 84b extending rearward and upward is provided at the center of each downward claw 84. On the other hand, in the housing 27, a rectangular through window 27 is formed in a portion of the rear wall 27c corresponding to the cut and raised piece 84b.
Then, a plate material 9 having a groove d formed therein and having a groove 9a opening upward is attached to the front side of the wall 27c, and a claw insertion space S is formed between the groove 9a and the through window 27d. There is. In addition,
Stoppers 27e are provided on both left and right edges of the housing 27. Then, the downward claw 84 is first slightly inserted into the claw insertion space S from above, and then the operation piece 8 is bent toward the downward claw 84, and in that state, the operation piece 8 passes through the stopper 27e. When it is pushed to the position, the bending operation force on the operation piece 8 is released there, and the downward claw 84 is further pushed in, the cut-and-raised piece 84b is inserted at the insertion end of the cut-and-raised piece 84b.
The downward claw 84 engages with the upper edge of the upper edge and is held so that it cannot move up and down. Therefore, the operation piece 8 is in a state in which it is hinged to the downward claw 84 so as to be vertically rotatable via the resin hinge 84a. Since the housing 27 is provided with the stopper 27e, when the operation piece 8 tries to rotate upward from the horizontal position, the tip end portion 82 abuts the lower surface of the stopper 27e to rotate further. The operation is prohibited. Also, the operation piece 8
Is set in a horizontal position, the operation piece 8 is set to be located at a portion displaced from the center of the opening 23 toward the downward cutout window 77.

With such a structure, the opening 23 formed at the boundary between the top plate 7 and the uppermost drawer 2.
As shown in FIG. 8, when the finger f inserted into the upper plate 7 is to be hooked from the lower surface side to the opening edge inner surface 77a side of the downward cutout portion 77 of the top plate 7, the operation piece 8 is pressed by the finger f. The pivotal retracting operation is performed downward, and the insertion space for the finger f is expanded. Therefore, the finger f can be inserted without any limitation.
Then, the inserted finger f is hooked on the opening edge inner surface 77a side and pulled, whereby the whole wagon 1 can be moved to the front side. In addition, as shown in FIG. 9, the finger f inserted into the opening 23 is inserted into the upward cutout 22 of the drawer 2.
The uppermost drawer 2 can be pulled out by hooking the handle protrusion 27b from above and pulling it. further,
As shown in FIG. 10, when the finger f inserted into the opening 23 is hooked on the step portion 83 of the operation piece 8 of the drawer 2 from the lower surface side and pulled, the operation piece 8 is in contact with the stopper 27e. The operating force is transmitted to the uppermost drawer 2 and the drawer 2 can be withdrawn.

Therefore, according to the wagon of this embodiment,
Even if an attempt is made to operate the uppermost drawer 2 and a hand is applied from the lower surface side from the existing concept, the operation piece 8 is displaced to the downward cutout window 77 side from the center of the opening 23. Since it is arranged, the operation piece 8 can be naturally put on the hand, and the uppermost drawer 2 can be reliably pulled out. Further, since the operation piece 8 rotates downward and retracts when the downward cutout window 77 is put on a hand, it is possible to eliminate a decrease in operability of the downward cutout window 77 at the same time.

The present invention is not limited to the above embodiment. For example, as shown in FIGS. 11 to 13, the operation piece 108 may be fixed to the housing 27. In this case, the tip portion 108a of the operation piece 108
