Abstract

(57) [Summary] [Problem] To use a ladder so that the ladder does not fall down even if work is performed on the ladder. SOLUTION: A support member is attached to a side of a pillar of a ladder,
It is hard to fall to the side.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a ladder, and more particularly, to a ladder that prevents a person from falling sideways when riding.

[0002]

[Prior art]

 Conventionally, ladders were manufactured not only as ladders but also as ladders, that is, ladders that were folded in two and used as ladders.

[0003]

[Problems to be solved by the invention]

 However, when used as a conventional ladder, the tendency is particularly remarkable when used as a ladder, but there is a drawback that the ladder easily falls down to the side during use. The present invention has been made to solve this problem and ensure safety during use.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the ladder in the present invention is provided with a support member for the side to prevent the ladder from falling to the side during use.

[0005]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. FIG. 1 shows a conventional ladder. FIG. 2 is a view showing a place where a conventional ladder is folded in two and used as a stepladder. FIG. 3 is an example of the ladder according to the present invention. FIG. 4 is a diagram showing a place where the ladder according to the present invention is folded in two and used as a stepladder. It is preferable that the support members 2 are provided on the columns 1 on both the left and right sides, respectively. In the case of FIG. 4 as well, it is more effective to attach the support member 2 to the column 1 in the same arrangement as that of FIG. 3 in order to prevent overturning due to torsion. A support may be attached to the column in position.

FIG. 5 is a drawing showing an example of a mounting portion of a support member. As shown in FIG. 6, not only can the support member 2 freely change the angle between the (support member) and (support column) with respect to the support column 1 as indicated by the arrow, but also the support member 2 has an arrow around its longitudinal axis. There is a structure that can be rotated like this. By doing so, the installation position of the landing section 3 can be freely selected. FIG. 6 shows an example of a structure for further adjusting the length of the support member 2. In addition, the side in the present specification does not necessarily indicate one direction but refers to all directions in which the ladder may fall.

[0007]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. That is, in the conventional type shown in FIGS. 1 and 2, when a person works with force on a ladder or a stepladder due to lack of support, the person often falls laterally. In addition, when a ladder is used upright, that is, when it is used at an angle close to vertical, the ladder is often bent back even if a person just rides on it. Even in such a case, if the ladder is used to support the side so that the ladder does not bend back using the support material according to the present invention, it is safe to stand on the ladder at an angle close to vertical. Can work.

Further, the support according to the present invention can have a more active role. In other words, the ladder is normally used as a support by touching something near its upper end, but if there is no such suitable support, use the support material according to the present invention as a support for the ladder. Is also possible. When a support is used for such a purpose, it is within the scope of the present invention to provide a plurality of supports for one support.

In describing the effects of the present invention, the term ladder is mainly used. The concept of the ladder used in the present invention includes: (1) a ladder that can be extended to two or three steps, and (2) Includes those that can be folded and used as stepladders.

As shown in FIG. 6, if the length of the support member is adjustable, the angle between the support member and the column can be changed, and the support member can rotate around its own longitudinal axis. In addition, the position where the landing part is set can be more freely selected. Therefore, the safety of the work is further increased.
