Abstract

The object of invention is an adjustable device applicable to climbing on wooden and concrete, polyester or metallic poles which enables climbing and safe work on poles of various diameters or which can be simply adjusted to the variable pole circumference due to its conical shape during the very climbing respectively, without any danger of slippage for the climber. The adjustable device for climbing on wooden and concrete, polyester or metallic poles according to the invention is composed of an embracement shackle (1) attached in a movable manner through a regulating mechanism (3) to a foot (4) as well as a movable console (8) connected in an adjustable manner through a mechanism (6) with a traction arm (7) in such a way that the grasp to the pole by the embracement shackle and the movable console occurs in three points always, irrespective of the pole diameter.

Description

ADJUSTABLE PREPARATION FOR CLAMPING ON WOOD AND CONCRETE, POLYESTER OR METAL RODS The subject of the invention is an adjustable climbing device for wooden and concrete, polyester or metal poles, which is useful and allows climbing and safe work on poles of different thicknesses, ie adjust to the changing range, or conical shape of the pole during climb, without the risk of the climber slipping.

2o The invention belongs to Class A63B 27/00 of the International Patent Classification.

A technical problem that is successfully solved by the present embodiment of the device according to the invention is the construction and implementation of such a climbing mechanism that will allow easy adjustment of the climbing device to different ranges of masts without descent or special additional loading of the climber.

Wooden and concrete, polyester or metal poles for use as supporting poles for overhead lines, telephone lines, street lighting and the like. have insulators through which wires run through. In addition, distribution boxes, transformers, etc. may be installed on top of such poles. All these parts are subject to failures caused by various technical causes, atmospheric discharges, etc. For this reason, it is necessary to climb on such a pole from time to time and perform certain work on it.

The problem with climbing such poles is that the different poles have different thicknesses, and the poles are usually conically shaped, which means that the dimensional difference between the diameter at the bottom and the diameter at the tops can be quite big. When climbing such a pole, however, the climber does not have much opportunity to adjust. adapting a climbing device to the thickness of the pole to which it is climbing.

is A technical problem that has not been successfully solved by climbing mechanisms so far is the implementation of such a device for climbing wooden and concrete, polyester or metal poles, which will be useful for climbing on poles of different thicknesses, and will also allow easy adjustment to different thicknesses The poles will also be useful for climbing wooden as well as concrete, polyester or metal poles.

Previous solutions for pole-climbing systems consisted of more or less unsuccessful attempts to implement aids that did not provide safe climbing and did not allow work on top of the pole. One such solution is also described in patent document WO 97/43016, which does not, however, successfully resolve the technical problem posed.

Also, the solution described in patent document WO 94/19063, which is intended for climbing on poles having a special profiled groove, does not solve satisfactorily the technical problem. As an accessory for pole climbing, the solution described in document WO 95/15790 also serves. this solution involves the insertion of specially designed screw nuts into the pole and then, when climbing, the inserting of the special nozzles into the adapted body of the screw nozzle. The solution does not provide a satisfactory io effect, and the screw nozzles need to be screwed into the pole even before it is installed, which only increases the cost of implementation.

In addition to the described devices, there are also known climbers that attach to each leg and are made up of a fixedly connected hug and foot. The foot is fixed by the climber to the leg, and the climb is performed in such a way that the climber alternately moves one and the other leg, and thus also the embrace arch along the pole. Climbers made in this way allow climbing only along certain dimensions of the poles, depending on the distance between the bow arch and the foot. Therefore, climbers with different sizes of arches should be used when climbing on differently thick poles, or the position of the climber at the height and narrow pole is unstable.

The adjustable climbing device on wooden and concrete, polyester or metal poles according to the invention consists of a controllable connected arch with a foot via a control mechanism, and an adjustable, movable bracket connected via a pull-arm mechanism so that the grip of the pole with the arc and the movable bracket is always at three points, regardless of the thickness of the pole.

The invention will be explained in more detail on the basis of an embodiment and accompanying drawings, of which:

Figure 1a is a schematic view of an adjustable climbing device on wooden poles in a top view set for climbing broad poles;

Figure 1b is a schematic view of an adjustable climbing device on wooden poles in top view set for climbing narrow poles;

Figure 2a is a schematic illustration of an adjustable climbing device for concrete, polyester or metal poles in a top view set for climbing wider poles;

Figure 2b is a schematic illustration of an adjustable climbing device for concrete, polyester or metal poles in a top view set for climbing narrow poles.

The adjustable device of the invention shown in Figures 1 and 2 is useful for climbing wooden as well as concrete, polyester or metal poles. The basic structural features of the device according to the invention are the same, the only difference is that the clamping teeth on the pole arch and the movable bracket have 2 ', 9' and 10 'clamping teeth while concrete, polyester or metal poles made of rubber pads 2, 9 and 10. Therefore, in describing the preparation according to the invention, we will describe the preparation with rubber pads, that is, for climbing on concrete, polyester or metal poles, which also applies to the climbing device on wooden poles.

The adjustable climbing device on concrete, polyester or metal poles according to the invention consists of a clamping arch 1 at the end of which a rubber pad 2 is mounted, with the clamping arch 1 being movably attached to the foot 4 on which a rubber stirrup 5 is mounted. with strap and buckle. From the foot 4, a movable bracket 8 is mounted, adjustable by means of a mechanism 6 with a pull lever 7, which has two rubber pads 9, 10 installed at the end. grip teeth 2 ', 9', 10 '.

When adjusting the device according to the invention, first, by means of the control mechanism 3, the correct distance of the clamping arc 1 is adjusted, and by the mechanism 6 with the crank 7, the position of the movable bracket 8 so that the device rests on the pole on which it is intended to climb via the rubber pads 2, 9 and 10 . While climbing the variable height pole, then by simply pulling the pull lever 7 through the mechanism 6, the sliding bracket 8 is moved closer to the pole, so that there is always an optimal grip between the devices of the invention and the pole at three points.

The foot 4, on which a rubber stirrup 5 is mounted with a clamping strap and a buckle, is designed to fit any shoe size. The rubber stirrup 5 holds the clamping strap in such a position that it is quick and easy to place the leg preparation. The device according to the invention is fixed to the leg only by pulling the clamping belt through the sliding buckle. In the same way, we also remove the preparation from the foot.

The main feature of the adjustable device for climbing concrete, polyester or metal poles according to the invention is its simple adaptability to different thicknesses of the poles by adjusting the position of the clamping arc 1 by means of the control mechanism 3, or by the simple possibility of adjusting the position of the movable bracket 8 by means of a mechanism 6 with a drawbar lever 7 while climbing. In this way, the device according to the invention replaces several size types of standard climbers, and while climbing a conically shaped pole, the device is always in contact with the pole at three points through rubber linings 2, 9, 10 or teeth 2 ', 9',

10 '.

Only the preparation body as well as the clamping arch 1 are made of hollow profiles and not of solid materials, as is the case with climbers known so far.
