Description

Safety hoop for vertical ladder

The present invention relates to a safety hoop for a vertical ladder, more specifically, by allowing the safety hoop to be detachably separated from the vertical ladder, thereby enabling the selective position adjustment of the safety hoop basically improved workability as well as products accordingly. The safety hoop can be improved, and the safety hoop has a single structure, and a support for supporting the safety hoop is provided to simplify the structure of the entire safety hoop. This simple and easy operation leads to an improvement in work efficiency, and also, a curved structure between the connection portion and the armrest portion of the safety hoop and between the armrest portion and the waistrest portion may cause the operator to hit the safety hoop. Safety accidents due to the cushioning function It is about a safety ladder for vertical ladder that can be prepared in advance.

In general, the vertical ladder refers to a ladder that is used for the worker to move to perform a height work in a high position or to move from a lower workshop to an upper workshop.

In addition, the safety hoop is provided at regular intervals so that the worker can support the body on the vertical ladder during movement or work through the vertical ladder.

Here, as an example, the vertical ladder and the safety hoop of the prior art will be described as follows.

As shown in Figures 1 to 3, the vertical ladder 5 of the prior art is spaced between a pair of vertical stand (5a) and a pair of vertical stand (5a) extending parallel to the vertical spaced at a predetermined interval It comprises a plurality of footrest (5b) connected and spaced at equal intervals.

Each of the vertical poles 5a is provided with a safety hoop 7 which is fixedly bonded to one end thereof and the other end thereof forms a closed curve structure.

Here, the safety hoop 7 is composed of a pair spaced up and down a predetermined interval, and has a structure that is provided with a plurality of support (9) connecting each of the upper and lower pair of safety hoop (7).

Safety hoop for the vertical ladder of this configuration is able to move upward by stepping on the footrest (5) in the state of holding the vertical stand (3) on both sides by hand when the worker moves to a high place on the vertical ladder (5).

And, if you take a rest or work during the movement will be able to relax or perform the desired work in the state to rely on the body to the safety hoop (7).

However, the safety hoop for the vertical ladder of the prior art has a problem that the safety hoop is integrally fixed and bonded to the vertical ladder, thereby making it impossible to selectively adjust the safety hoop, resulting in very poor workability.

In addition, since the safety hoop is composed of a pair, there was a problem of increased cost and installation work complicated and cumbersome due to the safety hoop manufacturing.

In addition, since the entire shape of the safety hoop has a straight structure, the safety hazard is greatly reduced, such as injury to the operator when hitting the corners, etc., and thus, the risk of safety accidents is very high.

The present invention has been made to solve such a problem, by allowing the safety hoop to be detachably separated from the vertical ladder, it is possible to selectively position the safety hoop basically improved workability as well as improved product reliability accordingly The purpose of the present invention is to provide a safety hoop for a vertical ladder that can be achieved.

In addition, by making the safety hoop a single structure and providing a support for supporting the safety hoop to simplify the structure of the entire safety hoop, it is possible to reduce the cost of the single structure and to simplify the installation work and improve the work efficiency. Another object is to provide a safety hoop for the vertical ladder that follows.

In addition, the bending between the connection portion and the armrest portion of the safety hoop and between the armrest portion and the waist support portion, due to the cushioning function provided by the bending structure in the event of a collision accident that may occur when the worker hit the safety hoop Another purpose is to provide a safety hoop for vertical ladders that can prepare for accidents.

Safety ladder for the vertical ladder of the present invention for achieving the above object is a plurality of vertical spaced apart at regular intervals and a pair of vertical poles extending in parallel up and down, spaced at equal intervals In the safety ladder for the vertical ladder so as to support the waist of the operator to a predetermined portion of the vertical ladder including a step of the safety hoop, the safety hoop is characterized in that it is detachably separated from the vertical ladder.

In addition, in the safety hoop for the vertical ladder according to an embodiment of the present invention, the safety hoop, a pair of connecting portions respectively connected to both sides of the pair of vertical stand of the vertical ladder; An arm rest portion extending forward from the pair of connecting portions to support the arm of the worker; And it may be configured to include a waist support to extend from the arm support to support the waist of the worker.

In addition, in the safety hoop for the vertical ladder according to an embodiment of the present invention, the safety hoop may be of an integral structure extending from the connection portion to the waist support portion through the arm support portion.

In addition, in the safety hoop for the vertical ladder according to an embodiment of the present invention, the bent portion bent in a curved structure between the connection portion and the armrest portion of the safety hoop and the armrest portion and the waistrest portion may be provided.

In addition, in the safety hoop for the vertical ladder according to an embodiment of the present invention, one end of which is connected to one side of the safety hoop and the other end is connected to the vertical stand of the vertical ladder is a support for supporting the safety hoop further It may be provided.

In addition, in the safety hoop for the vertical ladder according to an embodiment of the present invention, the support may be formed in a pair of the upper end is connected to the arm rest of the safety hoop, respectively, the lower end is connected to the vertical stand, respectively.

In addition, in the safety ladder for the vertical ladder according to an embodiment of the present invention, the support is to be formed in a bending structure bent equal to the curved shape of the safety hoop as the bending structure of the safety hoop is projected when viewed from above. Can be.

As described above, the safety hoop for the vertical ladder of the present invention is configured so that the safety hoop detachably detachable from the vertical ladder, thereby enabling the selective position of the safety hoop basically improved workability as well as reliability of the product accordingly The effect that can be improved can be obtained.

In addition, by making the safety hoop a single structure and providing a support for supporting the safety hoop to simplify the structure of the entire safety hoop, it is possible to reduce the cost of the single structure and to simplify the installation work and improve the work efficiency. Gain the effect that follows.

In addition, the bending between the connection portion and the armrest portion of the safety hoop and between the armrest portion and the waist support portion, due to the cushioning function provided by the bending structure in the event of a collision accident that may occur when the worker hit the safety hoop It is possible to prepare for safety accidents in advance.
