SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems in a worktable having a ladder-shaped main leg provided on a top plate so as to be foldable. It is an object of the present invention to provide an aluminum portable workbench in which the work safety is greatly improved when the work is carried on a top plate without substantially changing the structure and lightness of the portable workbench.

[0007]

In order to achieve the above object, an aluminum portable workbench according to the present invention comprises a ladder-like main leg made of an aluminum member at both ends of a top plate made of an aluminum member. On a portable workbench that can be folded along the back side of the top plate.
A first feature is that a handhold member is attached to a main leg extending from a corner of a portion or a top plate so as to be foldable along the main leg from a standing position.

[0008] Further, the handle member is provided at four corners of the top plate.
Or a vertical member of the main leg extending from the four corners,
Being foldable along the vertical member ,
The second and third features are that a slip stopper made of rubber or the like is attached to the handle member.

[0009] Further, in the standing and folding mechanism of the hanging member, the hanging member is attached to the groove of the mounting piece of the hanging member fixed to the main leg extending from the even angle portion of the top plate, and the first and second members are firstly attached.
The first pin member is rotatably pivoted by the pin member, and the through hole of the handhold member through which the first pin member is inserted is formed in a slot shape so that the first pin member can move, and is separated from the first pin member. A second pin member is provided at a position to be inserted into the handle member. A first pin member and a second pin member located inside the handle member are connected by a spring, and a second pin member protruding from the handle member is provided.
The protrusion of the pin member is fitted into the notch formed on the upper part of the mounting piece against the force of the spring, and the handle member is erected at the corner of the top plate. The handle member is folded along the main leg by pulling upward and turning downward against the protrusion to fit the protrusion of the second pin member into a notch formed in the lower portion of the mounting piece. This is a fourth feature.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the aluminum portable workbench of the present invention will be described below. The same members as those in the related art are denoted by the same reference numerals. As shown in FIG. 3, the work table of the present invention has both top plates 3 made of aluminum members.
At the side end , a ladder-shaped main leg 4 made of aluminum
In a conventional portable worktable provided so as to be foldable along the back side of the top plate, a corner portion of the top plate 3 or a corner portion of the top plate 3
The handle member 6 is attached to the main leg extending from the main leg so as to be foldable from the standing position along the main leg. Handle member
6 is preferably folded along the vertical member of the main leg 4. Figure
1 and 2 are longitudinal members of the main leg 4 extending from a corner of the top plate 3.
In addition, the handle member 6 is connected to the vertical member of the main leg 4 via the mounting piece 12.
An example of a portable worktable with a mounting structure that can be folded along
It is shown.

The handhold member 6 serves as a handhold when the worker goes up and down on the top plate 3 serving as a work table, and performs work on the top plate, thereby improving safety and workability. As shown in FIG. 2, it is rotatable between the standing position A and the folding position B, and is folded along the side surface of the main leg 4.

As shown in FIG. 1, the handle member 6 extends from the four corners of the top plate 3 or the four corners of the top plate 3.
It is preferable to provide all the vertical members of the main leg 4, but the number of installations can be changed according to the use situation of the work table.
In addition, in order to ensure safety when the operator grips the handle member 6, it is preferable to provide a slip stopper 9 lined with rubber or the like at a necessary portion of the handle member 6, as shown in FIG. .

As shown in FIGS. 1 and 2, a bendable stay 7 is attached to the work table 1 between the top plate 3 and the step 5 as in the conventional work table. Stay 7 is at both ends 1
0, 11 are the step 5 of the main leg 4 and the top plate 3, respectively.
After the operation is completed, the stay 7 is bent at the bent portion 8 so that the work table 1 can be folded and moved as shown in FIG.

The upright and folding mechanism of the handle member 6 will be described in detail. As shown in FIG. 4, the handle member 6 is fixed to the upper part of the main leg 4 extending from the even angle portion of the top plate 3 as shown in FIG.
The handle member 6 is attached to the groove 13 of the mounting piece 12 of the above, and both are pivotally connected to each other with the first pin member 14, and the through hole 15 of the handle member 6 through which the first pin member 14 is inserted is formed. First
The pin member 14 is formed in a slot shape so as to be movable.

A second pin member 16 is provided at a position distant from the first pin member 14 so as to pass through the handle member 6, and the first pin member 14 and the second pin member 16 located inside the handle member 6 are provided. Are connected by a spring 17, and a projection 18 of the second pin member 16 protruding from the handle member 6 has a notch 19 formed on an upper portion of the mounting piece 12 as shown in FIG.
The handle member 6 is brought to a position standing upright at the corner of the top plate 3 so as to fit into the top 19 against the force of the spring 17. In this case, the first pin member 14 is located at the upper end of the slot-shaped through hole 15.

As shown in FIG. 5, in order to fold the handle member 6, the handle member 6 is pulled upward (in the direction of arrow X) against the force of the spring 17, and rotated downward from the standing position A. When it is brought to the folding position B, the handle member 6 moves upward (in the direction of arrow Y) by the action of the spring 17, and the second
The protrusion 18 of the pin member 16 is fitted into the cutouts 20, 20 formed at the lower part of the mounting piece 12, and as a result, the handhold member 6 is folded along the side surface of the main leg 4. in this case,
The first pin member 14 is located at the lower end of the slot-shaped through hole 15.

The top plate 3 and the main legs 4 of the work table 1 of the present invention are made of an aluminum member. For example, the top plate 3 is made of a combination of extruded aluminum members, a combination of an aluminum plate and aluminum members, and the main leg 4 and the step 5 are made of extruded aluminum members. The handle member 6 is also preferably made of a hollow extruded aluminum member. It is desirable to apply an uneven pattern or other non-slip processing to the surface of the top plate serving as a work table. Further, the main leg 4 can be made extendable and contractible as in the conventional case.

[0018]

Embodiments of the present invention will be described below. Example A top plate (dimensions: 1500 mm in length and 500 mm in width) in which an aluminum extruded shape (material: A6063S) and an aluminum plate (material: A5052P) are combined, a ladder-shaped main leg and a handle member made of the A6063 extruded shape. Was used to assemble a work bench having a structure shown in FIGS.

When this work table was used on an actual construction work site on a work surface provided at a high place on the construction work site, the work can be performed extremely safely due to the presence of the handle member. It was confirmed that workability was also improved.

[0020]

According to the present invention, the work safety is greatly improved without substantially changing the structure and lightness of the conventional portable worktable, and as a result, the workability can be expected to be improved. A portable workbench is provided.
