Abstract

The invention relates to a stair climbing handle, in particular to a manual stair climbing handle with unique appearance and performance. Mainly comprises an assembly box, a strip-shaped cylinder, a fixed positive sawtooth strip, a sliding supporting barrel, an inverted T-shaped motion box, an inverted T-shaped negative sawtooth strip, a movable wheel, a folding tenon handle, a telescopic handle, a spring hole, a hanging spring, a return gravity ring, an automatic pullback spring and the like. The device is characterized in that a strip-shaped cylinder is arranged in a rectangular assembly box, a fixed forward sawtooth strip is arranged in the outer side of the cylinder, a sliding support tube is arranged on the periphery of the cylinder, an inverted T-shaped motion box is arranged on the outer side of the cylinder, an inverted T-shaped reverse sawtooth strip is arranged in the box, a movable wheel is arranged at the top end of the reverse sawtooth strip, a tenon handle is arranged at the front end of the inverted T-shaped motion box, a telescopic handle is arranged on the tenon handle, spring holes are formed in two ends of the bottom of the inverted T-shaped reverse sawtooth strip, hanging springs are arranged in the spring holes, a return gravity ring is arranged at the front end of the sliding support tube, and an automatic return spring is arranged. The hand-operated stair climbing handle made by the technology is labor-saving in stair climbing and wide in practicability.

Description

Hand-operated stair-climbing handle

Belongs to the technical field of:

the invention relates to a stair climbing handle, in particular to a manual stair climbing handle with unique appearance and performance.

Background art:

the stair climbing assistance products used at present are various in types, but most of the stair climbing assistance products need to consume electric energy, are high in manufacturing cost, particularly carry the climbing assistance products of the electronic unit, and have the defects that circuit elements are fine and complex, easy to damage, high in maintenance cost and the like.

The invention content is as follows:

the invention aims to provide a manual stair climbing handle which is free of an electronic unit and electric energy consumption, simple in structure, novel in appearance and unique in performance.

In order to achieve the purpose, the invention adopts the following technical scheme: a bar-shaped cylinder is arranged in a rectangular assembly box, a fixed positive sawtooth strip is arranged in the outer side of the cylinder, a sliding supporting barrel is arranged on the periphery of the cylinder, an inverted T-shaped motion box is arranged on the outer side of the barrel, an inverted T-shaped reverse sawtooth strip is arranged in the box, a movable wheel is arranged at the top end of the reverse sawtooth strip, a tenon handle is arranged at the front end of the inverted T-shaped motion box, and a telescopic handle is arranged at the upper end of the tenon handle. Spring holes are arranged at two ends of the bottom of the inverted T-shaped reverse sawtooth strip, hanging springs are arranged in the spring holes, a return gravity ring is arranged at the front end of the sliding support cylinder, and an automatic pull-back spring is arranged between the tenon handle and the upper end of the inverted T-shaped motion box.

The manual stair climbing handle made by adopting the technical scheme has the advantages of economic manufacturing cost, no occupation of building area and wide practicability.

Description of the drawings:

FIG. 1 is a schematic front view of the present invention.

Fig. 2 is a perspective view of the present invention.

Fig. 3 is a perspective view of the present invention.

The specific implementation scheme is as follows:

as shown in fig. 1, fig. 2 and fig. 3, an assembly box 1 is arranged at an equal height (in a wall) parallel to a stair handrail on the left wall or the right wall of an original staircase of a house, a strip-shaped cylinder 2 is arranged in the assembly box 1, a fixed positive sawtooth strip 3 is arranged in the outer side of the strip-shaped cylinder 2, a sliding support barrel 4 is arranged on the periphery of the strip-shaped cylinder 2, an inverted T-shaped motion box 5 is arranged on the outer side of the strip-shaped cylinder 4, an inverted T-shaped reverse sawtooth strip 6 is arranged in the motion box 5, a movable wheel 7 is arranged at the upper end of the inverted T-shaped cylinder 6, a tenon handle 8 is arranged at the front end of the motion box 5, a telescopic handle 9 is arranged at the front end of the telescopic handle 8, a spring hole 10 is arranged at the two ends of the bottom.

When the folding tenon type human body climbing assisting device is used, the folding tenon handle 8 is turned to the left lower side (or the right lower side) to be in a horizontal state, the tenon top of the folding tenon handle 8 can force the reverse sawteeth on the inverted T-shaped reverse sawtooth strip 6 to be mutually hung with the forward sawteeth on the fixed forward sawtooth strip 3, the folding tenon handle 8 is repeatedly pushed and taken upwards (forwards), and the inverted T-shaped reverse sawtooth strip 6 can be simultaneously hung and separated upwards (forwards) from the fixed forward sawtooth strip 3 under the action of the hanging spring 11, so that the effect of assisting the human body to climb upwards to save labor is achieved. When the hand is separated from the tenon handle 8, the handle 8 can be quickly upwards restored to a vertical state under the action of the pulling force of the automatic pullback spring 13, at the moment, the inverted T-shaped reverse sawtooth strip 6 is separated from the fixed positive sawtooth strip 3 under the action of the hanging spring 11, and the structural part on the whole support cylinder 4 automatically slides back to the initial point under the pushing of the return gravity ring 12.

The manual stair climbing handle made by adopting the technical scheme has novel and unique appearance and simple operation, is particularly suitable for indoor and outdoor original stairs without elevators, and is more suitable for assisting in climbing stairs of vulnerable groups such as the old, the disabled and the like.
