Problems solved by technology

[0005] However, in the walking assistance device described in Japanese Patent Application Laid-Open No. 2016-154718, when an impact force is applied to the handle such as when the walking assistance device is overturned, there is a possibility that the pressing member applies an impact force to the piezoresistive sensor via the slide tube. , thus making piezoresistive sensor failure concerns
In addition, since the pair of piezoresistor sensors and the pressing member are arranged inside the sliding tube and the fixed tube, there is a problem that repair work is troublesome when the pair of piezoresistor sensors and the like fail.

no. 1 Embodiment approach

[0111] (A) for example, such as Figure 8 As shown, a pair of shafts 35b formed from a cross-sectional circle protruding from the two end faces of the circular plate portions 35a of each of the rolling members 35 disposed on each through hole 225 disposed in the rolling members of the shaft members 22L, 22R. A cross-sectional arc-shaped leaf spring (upper body) 81 protruded from the bottom surface portion of the respective recess 225a in the center position in the axial direction (front-rear direction) of the through hole 225 is respectively formed. Further, each rolling member 35 is made upward.

[0112]Thereby, each of the rolling members 35 is biased upward by a leaf spring (upper body force member) 81, and pressing the inner peripheral surface of each sliding member 23L, 23R. As a result, it is possible to suppress loosening in the up and down direction of each slide member 23L, 23R, so that the direction of the operating force of the handle member 25L, 25R can be further reli...

no. 2 Embodiment approach

[0114] (B) Additionally, for example, a plurality of spherical rolling components are disposed in the circumferential direction of the outer peripheral surface of each of the outer circumferential surfaces of each shaft member 22L, 22R may be replaced with a roller-shaped rolling member 35. Specifically, a plurality of concave portions of the outer circumferential surface of each of the outer circumferential surfaces of the respective shaft members 22L, 22R may be formed along the axial direction, and the sphere is disposed in each recessed member as a rolling member.

[0115] Thereby, even if the user is dejected on the travel assist device 10, the body weight is applied to each of the handle members 25L, 25R, and the handle member 25L, 25R can be made in the front-rear direction, in other words, in the shaft member 22L. The axial direction of 22R is smoothly sliding. As a result, in a state where the user is applied to the travel assist device 10, the handle member can be reliab...

Embodiment approach

[0117] (C) Further, for example, it may be used instead of each of the operating direction detecting devices 71L, 71R, and Figure 9 as well as Figure 10 The respective operating direction detecting devices 91L, 91R are shown. The operating direction detecting means 91L, 91R are left and right pairs, and the handle frames 51L, 51R are configured or left, so based on Figure 9 as well as Figure 10 The operating force direction detecting device 91L on the left will be described, omitting the description of the operating force direction detecting device 91R on the right side.

[0118] Such as Figure 9 As shown, the operating force direction detecting device 911 includes a base member 92, a moving member 93, a pair of pressure sensitive sensors (moving direction detecting components) 75. The base member 92 is a substantially the same structure as the base member 72 of the above embodiment. Specifically, the base member 92 is the same as the base member 72 of the above embodiment, a...

Abstract

A walking assistance device is provided with: a main frame having a pair of left and right handle frames; a pair of left and right shaft members; a pair of left and right sliding members; a pair of left and right handle members; a pair of left and right operation force direction detection devices which are respectively provided to opposing side wall sections of the pair of handle frames and are configured so as to detect the direction of operation force acting on the pair of sliding members in the axial direction with respect to the pair of sliding members via the pair of handle members; and apair of left and right transmission members configured to transmit the operation forces acting on the pair of sliding members in the axial direction to the pair of operation force direction detectiondevices, respectively.

Description

Technical field [0001] The present invention relates to a walking assist device. Background technique [0002] A variety of techniques related to walking assisting devices that assist in elderly, etc. are proposed. For example, in the walking assist device described in Japanese Laid-Open Patent Publication No. 2016-154718, an operating force detecting device that detects the operating force of the handle is provided in the handle on the outer side of the handle. The operating force detecting device has a sliding tube that is slidably in the axial direction, and a fixed tube disposed inside the sliding tube. One end of the fixed tube is fixed to the main frame of the walking assist device. [0003] In order to detect the operation force acting on the axial direction of the sliding tube, the fixed tube has a pair of pressure sensitive resistance sensors configured relative to the fixed tube along the axial direction and separating the specified distance. The sliding tube has a pres...
