Abstract

Abstract A free stop retainer which comprises a retainer body formed with an engaging portion and an article retaining portion, a post formed with at least one groove formed longitudinally, the engaging portion elevationally slidably engaged in a longitudinal rail hole formed at the side wall of the post in such a manner that the article retaining portion is projected from the rail hole outwardly, the retainer body formed with a tapered surface opposed to the side wall of the post in such a manner that the space to the side wall becomes the maximum width at the lower end thereof and the minimum width at the upper end thereof. A lever is rotatably formed with a stopper at one end thereof and the stopper is guided on the tapered surface. The lever is elastically urged by a spring in the direction that the stopper urges the side wall of the post. Thus, the free stop retainer can be elevationally slidably engaged with the longitudinal rail hole formed at the side wall of a hollow post, and can also be fixedly secured at the desired position by a simple manual operation without using a tool.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 241 words
A free stop retainer comprising: (a) a retainer body (2) with an upper and a lower side, an engaging portion, (2a), and an article retaining portion (2b); (b) a post (1) with a side wall (1e) having a rail hole (5), said side wall (1e) having an inner and an outer surface also at least one longitudinal groove (1d), said engaging portion (2a) being elevationally slidably engaged in the longitudinal rail hole (5) of the side wall (1e) in such a manner that said article retaining portion (2b) is outwardly projected from the rail hole (5) of the side wall (1e); (c) a tapered surface extending from said engaging portion (2a) along one of the surfaces of the side wall (1e) to define a groove (2g) with an upper closed end and a lower open end in such manner that the space next to the side wall is at the maximum width at the lower end of the defined groove (2g) and at the minimum width at the upper end of the defined groove; (d) a lever (3) rotatably held in the article retaining portion (2b) with a stopper (3b) at one end and a lever actuating portion at the other end thereof, the stopper (3b) being disposed in the defined groove (2g) and guided along the tapered surface, and, (e) spring means acting on the other end of said lever (3) urging said stopper (3b) against the side wall (1e).
Claim 2
Dependent Claim 241 words
A free stop retainer comprising: (a) a retainer body (2) with an upper and a lower side, an engaging portion, (2a), and an article retaining portion (2b); (b) a post (1) with a side wall (1e) having a rail hole (5), said side wall (1e) having an inner and an outer surface also at least one longitudinal groove (1d), said engaging portion (2a) being elevationally slidably engaged in the longitudinal rail hole (5) of the side wall (1e) in such a manner that said article retaining portion (2b) is outwardly projected from the rail hole (5) of the side wall (1e); (c) a tapered surface extending from said engaging portion (2a) along one of the surfaces of the side wall (1e) to define a groove (2g) with an upper closed end and a lower open end in such manner that the space next to the side wall is at the maximum width at the lower end of the defined groove (2g) and at the minimum width at the upper end of the defined groove; (d) a lever (3) rotatably held in the article retaining portion (2b) with a stopper (3b) at one end and a lever actuating portion at the other end thereof, the stopper (3b) being disposed in the defined groove (2g) and guided along the tapered surface, and, (e) spring means acting on the other end of said lever (3) urging said stopper (3b) against the side wall (1e).
