Problems solved by technology

In this way, due to the instability of the electrical components, once a fault occurs, it will cause loss of power or slippage, which will easily cause the user to fall, and there is a large potential safety hazard.
[0006] In order to solve the above-mentioned problems, the applicant once applied for a patent for a method of assisting stair climbing to prevent falls, which introduced a device for assisting stair climbing, but there are still some structural designs in the device that are not reasonable enough, and the handrail clamp The tightening effect is poor, and the defect of using security is not enough

Embodiment 1

[0050] Example 1: See Figure 1-4 One type of stadium is tie rod device, including the tie rod 1, which is horizontally disposed, one end of the tie rod 1 is the taciting end, the tapered end of the lever has two downwards (based on the means used in the device) Description) The extension arm 3, the inner side of the two card connecting arm 3 and the outer surface of the tie rods between the two are enclosed in the bayonet 2; the bayonet width direction and the lever length direction and the bayonet can be slidably The armrest 14 of the stairs is; it is characterized by that the tie rod includes a cartridge segment and a pulling section, and the signal of the left side is fixed to the card opening section, and the card of the right side is fixed to the pull section, the card The front side of the mouthpiece and the pulling section relies on the vertical hinge shaft 25 which is rotatable, and the barrier segment and the pull section have a width of the rotation slit 26 gradually inc...

Embodiment 2

[0079] Embodiment 2, in the present embodiment and the first embodiment, the structure is in that the active abutment mechanism is canceled, and the two card joints are set to two fixed card joints, the remaining structure and the first embodiment. Thus, the fixed card joint can be directly supported, so that the support process of the above effect is more stable.

Embodiment 3

[0080] Embodiment 3, in the present embodiment and the first embodiment, the structure is different in that the card connector on the left side of the bayonet is set to the fixed card joint, and the card connector on the right is directly set to the active card joint, the remaining structure and the embodiment. 1 is the same.

[0081] In this way, the advantage of the two types of card connector structures can be balanced. When the device uses a rotation force, press the button to drive the active card joint to extend and rely on the cam, form two fixed card joints, and then combined with rotation slot It is possible to increase the addition effect of the right side card switch arm rotation angle, which can better ensure the clamping of the handrail, better ensure the stability and reliability of the support process. When the device moves forward without the needle, loosen the button, the active card joint relies back to the spring force to retract backward, and the convenience ba...

Abstract

The invention discloses a pull rod device for climbing stairs, which comprises a pull rod arranged horizontally as a whole, one end of the pull rod is a clamping end, and the clamping end of the pull rod has two downwardly extending clamping arms arranged at intervals. The inner side of the clamping arm and the lower surface of the pull rod between the two form a bayonet; the width direction of the bayonet is consistent with the length direction of the pull rod, and the bayonet can be snapped into the handrail of the stairs by sliding back and forth; it is characterized in that the pull rod includes The bayonet section and the pull section, the snap arm on the left is fixedly connected to the bayonet section, the snap arm on the right is fixed on the pull section, and the front side of the butt end of the bayonet section of the pull rod and the pull section relies on a vertical hinge The shaft is rotatably connected, and there is a rotating gap whose width gradually increases from the front side to the rear side between the bayonet section and the pulling section. The invention can help the elderly or the disabled go upstairs more labor-saving, can prevent falling, and has the advantages of better safety, convenient implementation and low cost.

Description

Technical field [0001] The present invention relates to the field of living aids of old or leg feet, which relates to a rod device for the upper staircase. Background technique [0002] The existing high-rise buildings are usually equipped with elevators, but some layers of layers and some old buildings are still relying on the stairs to achieve up and down the floor. In some housing structures, it is usually also installed steps. Stairs. In this way, for some old people or some legs and foot inconveniences, they will be more difficult to climb this step-style staircase, which is easy to fell, causing safety accidents. Especially for the elderly, falling in this step, the head collision of the head and steps will have a great threat to life safety. [0003] CN201711032317.3 An aircraft for up and down buildings is disclosed; including a lift stage disposed on a stair step in a residential, and a controller for controlling the rising platform. A lift is provided with a lifting sta...
