BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workbench used indoors or outdoors at a construction site of a building or a structure.

[0002]

2. Description of the Related Art At the construction site of a building or the like, at the time of painting outer walls, inner walls, ceilings, wiring of electric and telephone lines, plumbing, etc., both ends are supported by a frame body such as a stepladder, etc. The work table for erection of the work table is widely used. However, in the above-mentioned work, since the worker reciprocates on the work table many times, the stability of the work table is strongly required.

In particular, when the height is about 1 to 3 meters, there is no end to accidents in which the worker falls due to an unexpected impact or sudden impact on the workbench, and death in comparison with a fall from a high place,
It may cause a serious accident such as a bone fracture.

Therefore, until now, it has been obliged by the Ministry of Supervision to integrally work both end portions of the work table and the upper parts of the left and right frame bodies such as stepladders. A method of fixing by fixing a strong rubber band between the both ends of the stand and the frame of the stepladder has been adopted.

[0005]

However, in the above-mentioned conventional means, since the pulling force of the rubber band is not so strong, an accident in which the worker falls down when a shock is applied or the balance is lost and the worker falls Was occurring frequently. Therefore, there is a demand for a work table in which the tread material and the left and right frame bodies are integrated or separated by a simple operation, and moreover, are easily disengaged and do not move.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned drawbacks and problems and to cope with the conventional demands. , A tread material having both ends supported by the frame and installed, and an attaching portion and a locking portion are provided at a fixed interval on the end portion side of the tread material, and a stretchable band having strength. The one end of the body is fixed to the mounting portion, and the other end of the band body is provided with a hook portion that can be engaged with the locking portion, and the hook portion of the band body is hooked on a part of the frame body. The present invention relates to a work table which is formed by engaging with the locking portion.

[0007]

Therefore, the tread material is bridged between a pair of stepladders, the hook portion of the band body is removed from the locking portion, the band body is extended, and the band body is hooked to a part of the stepladder and then hooked again. By locking the part to the locking part, the band body is rigid and expandable and contractible, so the tread material is firmly fixed to the frame body and is stable, so the worker should perform safe work on the tread material. You can

When the work table is not used, the band body is removed from the frame body and the hook portion is locked to the locking portion,
Even when stacking tread materials, this band does not get in the way.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings. The frame body 1 such as a stepladder is generally widely used, and has, for example, a structure in which the upper ends of a pair of bifurcated leg portions 2 are connected by a horizontal rail 3.

The tread material 4 is a long plate formed of, for example, aluminum or the like, and has a shallow frame shape in which a side plate 6 having a short height is vertically provided at the front and rear side edges of the tread portion 5 so as to open downward. The uneven slip stopper 7 is provided on the surface of the tread portion 5.

On both sides of both end portions of the above-mentioned step board material 4, mounting portions 8 and locking portions 9 are provided in parallel on the inner surfaces of the front and rear side surface plates 6 at regular intervals. A rigid and stretchable band body 1 having sufficient strength with the stopper 9.
It is multiplied by zero.

The band body 10 described above is, for example, a coil spring made of metal or a rubber band material, is elastic but has a strong pulling force, and one end thereof is fixed to the mounting portion 8 as described above. A hook portion 11 is provided at the other end so that the hook portion 11 can be engaged with the engaging portion 9.

Therefore, a pair of left and right frame bodies 1 such as stepladders are arranged at a predetermined interval, the tread material 4 is bridged between the pair of frame bodies 1, and the hook portions 11 of the respective band bodies 10 are locked. 9 and the band body 10 is hung on the horizontal rail 3 of the frame body 1 from below and the hook portion 11 is re-engaged with the engaging portion 9, the tread material 4 has a pair of left and right frame bodies at both ends thereof. It will be fixedly supported by 1. Therefore, even if an operator walks on the upper surface of the tread material 4, it does not come off or disassemble,
Also, it does not collapse even when an impact is applied.

Then, the hook portion 11 of each band body 10 is disengaged from the locking portion 9, and the band body is attached to the horizontal bar 3 of the frame body 1.
When the hook portion 11 is hooked on the locking portion 9 along with the band body 10 along the inner surface of the side plate 6, the band body 10 is not exposed on the surface and therefore does not interfere with transportation or storage. There is no risk of loss.

The present invention has been described above based on the embodiments of the drawings. However, the present invention is not limited to the above-mentioned embodiments, and may be modified as long as the constitution described in the claims of utility model is not changed. It can be carried out at any time. For example, the mounting portion 8 and the locking portion 9 may be provided so as to project from the outer surface of the side surface plate 6. Further, as shown in FIG. 4, the band bodies 10 are provided at the respective end portions of the left and right side surface plates 6 of the tread plate material 4, and the tread plate body 4 is laid over the horizontal rails 3 of the left and right frame bodies 1 in each state. The band body 10 of the side plate 6 is dipped into the lower surface of the horizontal rail 3, and each band body 1
The hook part 11 of 0 is hooked on the locking part 9 of the other side plate 6 to form an X-shape, or the hook part 1 is attached to one side plate 6.
When the band body 10 having No. 1 is provided and the other side plate 6 is provided with the engaging portion 9 so that the band body 10 submerged in the lower surface of the horizontal rail 3 is engaged with the engaging portion 9 of the other side plate 6. , Frame 1
And the tread material 4 can be firmly connected.

[0016]

In summary, according to the present invention, there are at least left and right frame bodies such as stepladders, and tread material which is erected with both ends supported by the frame body. A mounting portion and a locking portion are provided on the end side at regular intervals, and one end of a stretchable band body having strength is fixed to the mounting portion, and the other end of the band body is fixed to the locking portion. Since a hook portion that can be engaged is provided and the hook portion of the band body that is hooked on a part of the frame body is engaged with the locking portion, it is only necessary to install the tread material on a pair of stepladders. The tread material can be firmly fixed, and it will not fall or collapse even if it is slightly rocked or shocked, ensuring the safety of workers at the construction site and not using the tread material. It can be stacked without taking up lots of space when it is stored, etc. Functions and effects.
