Securing structure of a seat of a cart for use by the elderly and handicapped persons

Abstract

A cart includes a locating tube, a circular part, a bottom plate, and a control rod; the locating tube is secured on a frame of the cart; the circular part is secured at an upper end of the locating tube, and it has several gaps on an edge; the bottom plate is secured on a lower side of a seat, and it has a protruding part on a lower side; the seat is supported on the locating tube with the protruding part being held in the circular part; the control rod is pivoted on the lower side of the bottom plate, and it is normally in a first position and fitted in one of the gaps at a front end thereof, which has slopes on two lateral sides so as to become gradually narrower; the seat is angularly displaceable when the control rod is disengaged from the circular part.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the invention [0002] The present invention relates to a securing structure of an angularly displaceable seat of a cart for use by the elderly and handicapped persons, more particularly one, which can prevent the seat from hitting the associated part or producing noise to cause discomfort and annoyance to the rider. [0003] 2. Brief Description of the Prior Art [0004] In order for the elderly and the physically handicapped to be easily seated on the seats of carts especially provided for use by them, the seats are first angularly displaced so as to make the front edges thereof face the left or the right direction. And, the seats are turned back to the original orientation for the front edges to face the front again after people are seated thereon from the left or the right sides of the carts. [0005] Referring to FIG. 6, a currently existing cart 4 for use by the elderly and handicapped persons includes a frame, and a seat; the frame has a...

Benefits of technology

[0007] The securing structure of the present invention includes a locating tube, a circular part, a bottom plate member, and a control rod. The locating tube is held in and securely connected to an outer tube secured on an upper side of a frame of the cart. The circular part is secured at an upper end of the locating tube, and it has several gaps on an edge thereof. The bottom plate member is secured on a lower side of a seat of the cart, and it has a protruding part on a lower side thereof. The seat is supported on the locating tube with the protruding part being held in the circular part. The control rod is pivoted on the lower side of the bottom plate member. The control rod is normally in a first position and fitted in a selected one of the gaps of the circular part at a front end thereof, and it can be pivoted upwards by means of exerting an external force thereon; the control rod will pivot back to the first position when there one stops exerting force thereon. The seat is angularly displaceable when the control rod is pivoted and disengaged from the circular part. The front end of the control rod is formed with slopes on two lateral sides so as to become gradually narrower.

Problems solved by technology

Consequently, the pivotal control rod 42 will hit the circular part 441, and produce noise when the cart moves along, causing discomfort and annoyance to the rider.
