[0002]

2. Description of the Related Art Conventionally, when working at a high place,
Workers prepared lifting equipment such as stepladders and ladders and tools to be used there, and carried them while holding them with both hands. Also, when working on a stepladder, etc., many types of tools and materials such as nails, screws, hammering and screwdrivers may be required, but the operator must change the tools each time. He interrupted his work and went up and down a stepladder to get tools. Further, as described in Japanese Utility Model Publication No. 51-9461, a ladder and a column are erected on the upper surface, and wheels and leg rods are mounted on the lower front, rear, left and right corners of a base on which a tread plate is mounted. The rod is pivotally supported by a side end of a pivot plate pivotally attached to the base side, and is movable vertically when the pivot plate is pivoted. A connecting rod is pivotally attached to a lower end of the pivot plate. The connecting rods corresponding to the front and rear are connected to positions eccentric to each other on a shaft that is rotated by pedal operation, and are formed so that the connecting rods are moved in the direction of separation and approach when the shaft is rotated. A protrusion formed of a pin or the like protruding from one side of a rod member connecting the first and second cutouts of a locking plate suspended from the lower surface of the base; When the projection is engaged with the engaging portion of the first notch, the lower end of the leg rod is positioned higher than the wheel installation surface, and the second notch engages. There is arranged and formed by a stepladder to be positioned below than the installation surface of the wheel when engaged in part.

[Problem to be solved by the invention] When carrying a lifting device such as a stepladder or ladder by hand, both hands are used up, so even if you want to carry a tool box etc. at the same time, hold it in your hand. It was irrational because it was not possible to go back and forth between the work site where the elevating equipment was to be used. As described in Japanese Utility Model Publication No. 51-9461, in the case where a stepladder body fixed with both legs always open is installed on a base with casters, a measuring instrument and A large tool box with tools can be installed, but it has a special shape that is bigger and heavier, with legs always open, regardless of whether it is used or not, and is far from commonly used stepladders And could not be diverted to another. That is, in the device described in Japanese Utility Model Publication No. 51-9461, the use place and usage of the stepladder are inevitably restricted due to its shape, and the floor needs to be hard and flat, and the compactness is required. It is extremely difficult to carry the stepladder freely to the intended work place because storage, bringing it to a narrow place, assembling a stepladder while avoiding things under your feet, or moving to the second floor or outside, etc. can not be achieved at all. It was something. Therefore, the tools mounted on the stepladder base could not be transported naturally while being mounted on the base. In addition, in the device described in this publication, the tool box can simply be transported without the need for power, and the tool box is an off-the-shelf product. The box is placed on a “base” close to the ground or floor.When working on a stepladder, etc., the worker must interrupt the work every time the tool is replaced, etc. It was necessary to go down to the ground to get things, etc., and still had to go up and down the stepladder many times. Furthermore, in the invention described in this publication, the tool box is placed `` on the base '', that is, directly below the stepladder, so not only can not take out the tool from the stepladder, but also if you go to get the tool It was located far away, and had the inconvenience of making a circuitous detour.

[0004] In addition, although the lifting equipment such as stepladders and ladders are large and cannot be overlooked, they are often difficult to work because they cannot find the necessary tools for working at heights. Met.

[0005] In order to avoid wasting time on the stepladder or the like to get tools and so on while interrupting the work, there are cases where a screw or a hammer is temporarily placed on a stepboard such as a stepladder. They had problems with safety, such as dropping from the upper stepladder and losing important things or damaging the floor.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems of the prior art, the lifting and lowering device with casters according to the present invention has the following configuration. That is, a tread plate of a device for lifting such as a stepladder or a ladder (6)
As a structure for forming a pocket (7) between (6) or between the legs (1), (1), necessary tools and small materials can be stored therein.

[0007]

[Function] If you are going to work in high places, bring the stepladder to the site, open both legs of the stepladder and try to assemble the stepladder.
The pocket provided between the step plate on this side of both legs of the stepladder and the step plate facing the other side will be pulled between the two legs and spread horizontally. Also, if you try to close between the two legs to clear the stepladder after the work, the open pocket will bend and bend, forming a pocket like a bag or box. Will be closed naturally. In addition, this pocket is not necessarily fixed to a stepladder etc., and a pocket body with a wallet type or back type formed partially can be detached from the stepladder, so it is possible to carry it alone as needed It is.

[0008]

An embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a partial perspective view showing a first embodiment of the present invention. In the first embodiment, a pocket (7) is provided by utilizing a space between a step plate (6) and a step plate (6) on one leg of a lifting device such as a stepladder. The pocket (7) may be rigid or soft, but in any case, it may be necessary to open the tread plate so that the foot can be put on the tread plate (6). When the pocket (7) is provided, the step board (6) and the step board (6)
It is needless to say that may be provided in a stepped manner.

FIG. 4 is a partial perspective view showing a second embodiment of the present invention. In the second embodiment, a net-like or cord-like part is provided at a part between the tread plate (6) on this side of both legs of the stepladder and the tread plate (6) facing the other side, that is, at a part between both legs of the stepladder. A cloth-like or the like, or a folding, wallet-type or back-type pocket (7) is provided. Alternatively, a pocket (7) having the same shape as described above is provided between the step plate (6) on this side of the stepladder and the stepped step plate (6) facing the other side. In the pocket (7) provided between the former positions, when the stepladder is opened and assembly is to be performed, both ends of the pocket are pulled between both legs, and the entire pocket or a part of the mouth of the pocket is opened, so that the inside of the pocket is opened. We are creating a system in which stored tools can be taken out at any time. Since the pockets are spread horizontally,
Alternatively, by forming the pocket body only in the vicinity of the center between the legs, it is possible to prevent the pocket body from hitting the toes of the foot and obstructing the foot when climbing up and down the stepladder. In the latter pocket (7), it is the same as trying to form a pocket having a bag-like shape or a box-like shape by bending. The large storage area makes it easier to see the entire pocket from one leg when the pocket is opened. In the first embodiment and the second embodiment, the pocket (7) may be made detachable in consideration of the convenience of use of a lifting device such as a stepladder or a ladder. In addition, as described above, several inner pockets and outer pockets such as wallet type and back type, shallow pockets and deep pockets, etc. It is assumed that tools can be organized and stored. Therefore, the pocket (7)
Is not fixed to the step plate (6) of the stepladder or between the two legs, and a pocket having a shape suitable for each purpose of use and tools used by the stepladder is selected from among a plurality of pockets, and a ready-made stepladder is selected. It can also be easily attached to In general, the stepladder is provided with an opening prevention metal fitting for fixing both legs, but this can be used as a part of the pocket of the present invention. Also, if the pocket of the present invention is attached to a stepladder provided with casters on a part of the leg, even if more items are stored in the pocket, it can be easily transported and moved without requiring any force. Indeed, this pocket will also have the function of a dolly integrated with the stepladder.

FIG. 5 is a perspective view showing a third embodiment of the present invention. In a third embodiment, a folding wallet-shaped pocket (7) has a belt-shaped joint (8) at each end of the pocket (7) for connection to a foot plate (6) or a leg (1) of a lifting device. Is provided.

[0011]

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

When the two steps of the stepladder are to be opened to assemble the stepladder, the pocket provided between the stepboard on this side of the stepladder and the stepboard on the opposite side is pulled between the two legs and spread horizontally. The mouth of the pocket will open. In other words, if the tools used for high-altitude work are stored and stored in this pocket, the necessary tools can be taken out at any time at the stage of opening the legs to assemble the stepladder and assembling. Is what it is. Moreover, since the pocket is not placed directly on the ground or the floor unlike a general tool box, it does not damage or stain the floor, and its position is close to the worker's line of sight. There is no need to go up and down such as stepladders to search for tools or change tools by bending, which can improve work efficiency. In addition, the pockets that are spread horizontally can be used as accessory shelves for materials and tools that are useful when working on a stepladder, etc. The opened pocket (7) bends and bends, forming a pocket like a bag or a box, closing the opening naturally, and naturally storing materials and tools therein. Will be. In other words, instead of collecting and clearing the tools after the work is completed, they intend to store and store the tools used in the work as they are. Therefore, the operation of simply closing both legs of the stepladder ends the cleaning work and prevents the tools from being left behind somewhere. Further, since the stepladder and the tools necessary for the work can be integrated and stored, the tools cannot be found and cannot be prepared, so that it is not difficult to work. In addition, this pocket is not stored on the floor like a general tool box, but is stored in a state of being suspended on a stepladder, so there is no need for a special storage base for the tool box. It is.
