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, portable wagons have been developed which can be used as desk sleeves, side desks and the like. However, in the conventional one, a drawer is provided in a plurality of stages on a wagon body provided with casters, and the entire wagon can be moved to a desired position by applying an external force.

[0003] However, in the conventional one, although the end plate of each drawer is provided with an opening having a handle function, there is no place for the wagon main body to be hooked. For this reason, there is no problem in pressing and moving, but it is inconvenient when drawing out from under the desk. In addition, since small items such as writing utensils are often stored in the top drawer, it is desirable to increase the practicality by making the top drawer thin and the other drawers thick. However, if the uppermost drawer is provided with the same opening as the drawers of the other stages as in the related art, the uppermost drawer cannot be made thin, and the degree of freedom in design is impaired. There are drawbacks.

Accordingly, the present inventor has disclosed in Japanese Patent Application No. Hei.
In Japanese Patent Publication No. 0, a caster is attached to the bottom surface of a wagon body having drawers provided in a plurality of stages, while a top plate is provided on the top surface of the wagon body, and a hand is provided on the front end surface of the top plate from the bottom surface side. The upper cutout window is formed on the upper edge of the drawer of the uppermost drawer, and the upper cutout window is formed on the upper edge of the drawer that can be reached from the upper side, and the drawer is closed. In such a case, a configuration was developed in which a downward opening window and an upward opening window could face each other to form a single opening.

[0005] According to such a configuration, if the finger inserted into the opening is hung from the lower surface of the top notch in the top plate and pulled, the entire wagon can be moved forward.
The uppermost drawer can be pulled out by hooking the finger inserted into the opening in the upward cutout of the drawer from the upper surface side and pulling. Therefore, by forming the opening separately, the operability in transporting the entire wagon is improved, and only one half of the opening needs to be formed in the uppermost drawer. This has the effect of enabling flattening.

[0006]

However, in such a wagon, the uppermost drawer must be operated by putting a hand on the upper side. However, we customarily recognize that drawers are hand-held from the underside. For this reason, when the wagon is used, there is no case where the intention of operating the drawer causes the case in which the wagon body is operated, and the operation force at that time is not so large, so that there is no trouble that the wagon body moves. Anyway, there is a disadvantage that the hand must be reinverted from the top side and re-operated.

The object of the present invention is to eliminate such erroneous operations.

[0008]

In order to achieve the above object, the present invention employs the following configuration.

That is, in the wagon according to the present invention, a caster is attached to a bottom surface of a wagon body having a plurality of drawers, and a top plate is disposed on an 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 lower side can be formed, and the upper edge of the end plate of the top drawer can be reached from the upper side that can be reached from the upper side. A portable wagon configured such that a notch window is formed and a downward opening window and an upward opening window face each other to form a single opening when the drawer is closed. An operation piece that is integral with the drawer and that can be put on from the lower surface side is disposed between the notch windows in the unit.

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

In order to prevent the operation of the downward cutout window from being hindered by the presence of the operating piece, the operating piece is a movable one whose rear edge is hinged to the drawer, and the downward cutout window of the top plate. It is desirable to be configured so as to perform a rotational retreat operation downward by a pressing force when a hand put on a hand contacts.

At this time, in order to reduce the number of parts,
Conveniently, the operating piece is hinged to the drawer via a resin hinge.

As another mode for preventing the operation of the downward cutout window from being disturbed by the presence of the operation piece, the operation piece is a movable one having left and right side edges attached to drawers, And a device configured to perform a curving and retreating operation downward by a pressing force when a hand hung on the downward cutout window contacts.

When the operation piece is movable, it is desirable to provide a stopper for the operation piece to inhibit the upward retreat operation or the bending retreat operation.

The operation piece may be fixed to the drawer. In this case, in order to ensure the operability of the downward notch window, the operation piece has a notch in the center, and it is possible to insert the notch and reach the downward notch window of the top plate. It is preferable that it is constituted so that it can be performed.

[0016]

With such a construction, the entire wagon can be moved to the front if the finger inserted into the opening is hung on the lower notch of the top plate from the lower surface side and pulled.
Further, if the finger inserted into the opening is hung from the upper surface side of the drawer to the notch of the drawer and pulled, the uppermost drawer can be drawn. Furthermore, the uppermost drawer can be pulled out even when the finger inserted into the opening is hung on the operation piece of the drawer from the lower surface side and pulled.

Therefore, even if the wagon of the present invention requires the user to operate the drawer at the uppermost stage from the conventional concept, the operator must grasp the operation piece more than the downward cutout window. As long as it is set to be easy,
The uppermost drawer can be reliably drawn.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the wagon 1 has a caster 6 attached to the bottom surface of a wagon body 5 provided with a plurality of drawers 2, 3, and 4, and a top plate 7 disposed on the upper surface. Become.

The wagon body 5 is of a housing type having a front surface and an upper surface opened, and casters 6 are attached to four corners of the lower surface. A top plate 7 made of a synthetic resin is covered on the upper surface as shown in FIGS. The top plate 7 includes an upper plate portion 71, a side plate portion 72 suspended from the upper plate portion 71 on both side edges, a front plate portion 73 suspended from the upper plate portion 71 on the front edge side, and the upper plate portion. A flat plate having a back plate portion 74 hanging down from the base plate 71 to the trailing edge side. The lower surface of the upper plate portion 71 has a longitudinal rib 7 for reinforcement as shown in FIG.
5 and a lateral rib 76 are provided, and are integrally formed of a synthetic resin. The upper plate 71 constituting the upper surface 7b of the top plate 7 has a peripheral portion 7 so as to form a tray.
1a is formed higher than the central portion 71b.

A downward cutout window 77 is formed on the front end surface 7a of the top plate 7 so that a hand can be engaged from the lower surface side. To 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. More specifically, the downward cutout window 77 is formed by cutting out the center of the lower edge of the front plate 73 of the top plate 7, and the rear 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 a front plate portion 26. Case 2 made of synthetic resin disposed between
7, the housing 27 is exposed to the outside through a notch 26a formed at the center of the upper edge of the front plate 26, thereby forming the upward cutout window 22. I have. The housing 27 has a front surface and an open top surface, and has a ridge 27b formed on the front edge of the bottom wall 27a to facilitate a hand from the top surface side. And this case 2
A mounting portion 27g having a screw hole 27f is protrudingly provided on each of the right and left ends of 7, and a screw 27h having the back plate portion 25 penetrated is screwed into the screw hole 27f of the mounting portion 27g to be tightened. The housing 27 is fixed to the back plate 25. Note that the left-right dimension of the upward notch 22 is set to be the same as the left-right dimension of the downward notch 77,
When the drawer 2 is closed, these downward notches 77
And the upward cutout 22 face each other to form a substantially rectangular opening 23. And this opening 23
Has substantially the same shape as the handle openings 33 and 43 provided in the end plates 31 and 41 of the other drawers 3 and 4.

In such a configuration, in the present embodiment, the uppermost drawer 2 can be integrated with the hand 2 from the lower side between the cutout windows 22 and 77 in the opening 23. Operation piece 8 is provided. Specifically, as shown in FIGS. 4 to 7, the operation piece 8 is
7, which has a plane dimension accommodated in the opening edge thereof, and has a step portion 83 formed between the base end portion 81 and the tip end portion 82, and a hand can be put on the step portion 83 from the lower surface side. It is like that. On the other hand, at the three rear edges of the base 81, downward claws 84 integral with the operation piece 8 are hung down, and the boundary between each of the downward claws 84 and the base 81 is downward. Resin hinge 84a that is easily elastically deformed in the direction in which the mounting angle of the claw 84 is changed
Is formed. A cut-and-raised piece 84b extending upward and rearward is provided at the center of each downward claw 84. On the other hand, the housing 27 has a rectangular through window 27 at a portion of the rear wall 27c corresponding to the cut and raised piece 84b.
Then, a plate material 9 having a groove 9a opening upward is recessed on the front side of the wall 27c, and a nail insertion space S is formed between the groove 9a and the through window 27d. I have. In addition,
Stoppers 27e are provided on both left and right side edges of the housing 27. Then, the downward claw 84 is first inserted slightly into the claw insertion space S from above, and then the operation piece 8 is bent toward the downward claw 84, and in this state, the operation piece 8 passes through the stopper 27e. When the bending operation force on the operation piece 8 is released and the downward claw 84 is further pushed in, the cut-and-raised piece 84b is formed at the insertion end of the through-hole 27d.
And the downward claw 84 is locked so as not to move up and down. Therefore, the operation piece 8 is in a state of being vertically hinged to the downward claw 84 via the resin hinge 84a. Since the housing 27 is provided with a stopper 27e, when the operation piece 8 is to be rotated upward from the horizontal position, the distal end portion 82 comes into contact with the lower surface of the stopper 27e, and the rotation is further performed. Operation is prohibited. Operation piece 8
Is set in such a manner that the operating piece 8 is located at a position deviated from the center of the opening 23 toward the downward notch window 77 when is located at the horizontal position.

With such a configuration, the opening 23 formed at the boundary between the top plate 7 and the uppermost drawer 2 is formed.
As shown in FIG. 8, when the finger f is inserted into the opening edge inner surface 77 a of the downward notch 77 of the top plate 7 from below, the operation piece 8 is pressed by the finger f. A downward rotation operation is performed, and the insertion space for the finger f is expanded. Therefore, the finger f can be inserted without any care.
Then, the whole wagon 1 can be moved to the front by hooking the inserted finger f on the opening edge inner surface 77a side and towing. Further, as shown in FIG. 9, the finger f inserted into the opening 23 is
The uppermost drawer 2 can be pulled out by hooking it from the upper surface side to the ridge 27b for handholding. further,
As shown in FIG. 10, when the finger f inserted into the opening 23 is hung from the lower surface side of the step 83 of the operation piece 8 of the drawer 2 and pulled, the operation piece 8 comes into contact with the stopper 27 e. , The operating force is transmitted to the uppermost drawer 2, and the drawer 2 can be pulled out.

Therefore, according to the wagon of this embodiment,
Even if it is necessary to operate the drawer 2 at the top in order to operate the drawer 2 from the lower side of the existing concept, the operation piece 8 may be displaced toward the downward notch window 77 side from the center of the opening 23. Since it is provided, the operation piece 8 can be hooked naturally, and the uppermost drawer 2 can be reliably pulled out. In addition, when the hand is placed on the downward cutout window 77, the operation piece 8 performs the rotation and retreat operation downward, so that a decrease in the operability of the downward cutout window 77 can be eliminated at the same time.

Note that the present invention is not limited to only the above-described embodiment. For example, as shown in FIGS. 11 to 13, the operation piece 108 can be fixed to the housing 27. In this case, the tip 108a of the operation piece 108
Ridges 1 that can be used to hold hands from the bottom side
08b may be provided. Further, in this case, in order to prevent the operability of the downward notch window 77 from being lowered, a notch 108c as shown by an imaginary line in the figure is provided at the center of the distal end portion 108a of the operation piece 108. The notch 108c may be inserted so that a hand can be put on the downward notch window 77 of the top plate 7. In this case,
The uppermost drawer 2 can be pulled out by putting a hand on the left and right side edges of the distal end portion 108a. Further, an operation piece 208 as shown in FIG. 14 can be used. The operation piece 208 includes a downward claw 208 protruding downward from both left and right edges.
a is inserted into the claw insertion space S formed in the housing 27 in the same manner as in the above embodiment, and the cut-and-raised piece 208b provided on the downward claw 208a is engaged with the through window 27i provided on the side wall of the housing 27. A notch window 7 with a top plate 7 facing downward.
The operating piece 208 performs a curving and retreating operation downward by the pressing force when the hand on the hand 7 comes into contact, and the operability when pulling out the entire wagon 1 is secured. 27j is a stopper for preventing the operation piece 208 from performing a curving and retreating operation when pulling out the drawer 2. The operation piece 208 has a concave groove 2 for loosely fitting the stopper 27j in a horizontal position.
08c is provided. Other configurations can be variously modified without departing from the spirit of the present invention.

[0026]

According to the wagon of the present invention, a single opening is formed when the downward cut window formed on the top plate and the upward cut window formed on the uppermost drawer are joined together. In the portable device, an operation piece that is integral with the drawer and that can be hung from the lower surface side is provided between the notch windows in the opening. For this reason, even if it is attempted to operate the drawer at the top in order to operate the drawer from the lower surface side, even if it is set so that the operation piece is more easily accessible than the downward cutout window. By doing so, the uppermost drawer can be reliably pulled out, and the problem of erroneous operation of the frequently operated uppermost drawer can be solved.
