Abstract: A caster of an endless structure is provided which is almost jam-proof even in the case of a bigger gap. The caster includes a first wheel supported on a mounting leg, a second wheel supported by an axle on one end of a suspension arm of which the other end is supported by an axle which also supports the first wheel, and a wrap-around member which is wrapped around the first and second wheels. The wraparound member is formed an endless belt form by connecting independent pieces to each other. The outer peripheral section of each piece is provided with a wider section and when the wraparound member is depressed and warps, the wider section is adapted to touch a wider section of the adjacent piece, thereby preventing further depression.

Abstract: A conventional endless belt is made of a comparatively flexible member such as rubber. When the endless belt comes in contact with a gap, part of the belt is pushed inward against the gap to be depressed and as a result, a greater power is needed for the endless belt to climb over the gap and it becomes easily jamed. According to the present invention, a caster of an endless structure is provided which is almost jam-proof even in the case of a bigger gap. The caster comprises a first wheel 3 supported on a mounting leg 2, a second wheel 4 supported by an axle 8 on one end of a suspension arm 7 of which the other end is supported by an axle 6 which also supports the first wheel 3, and a wrap-around member 5 which is wrapped around the first and second wheels 3 and 4. The wraparound member 5 is formed an endless belt form by connecting independent pieces 25 to each other. The outer peripheral section of each piece 25 is provided with a wider section and when the wraparound member is depressed and warps, the wider section is adapted to touch a wider section of the adjacent piece 25, thereby preventing further depression.

Abstract: A walker apparatus includes a base, a pair of front roller mounted rotatably on a first shaft which extends from a front left side to a front right side of the base, a pair of rear rollers mounted rotatably on a second shaft which extends from a left side to a rear right side of the base, endless left and right foot belts engaging respectively one of the front rollers and one of the rear rollers, and a support unit disposed between the front and rear rollers to provide a supporting surface for the foot belts. The foot belts move independently and are to be treaded respectively by the left and right feet of the user, thereby preventing the action of the user's left foot from influencing the action of his right foot and vice-versa when the walker apparatus is in use. The walker apparatus may be used with a functional supporting frame that is in the form of a baby chair, a baby stroller, an exercise walker or any other suitable form.

Abstract: A pair of endless belt track assemblies attach to the frame of a hand truck and extend backwards from the ground wheels for a distance to facilitate travel on stairs or the like during the intervals when the ground wheels are out of contact with the stair treads. Rollers are situated between the front, back, lower and upper regions of a pair of spaced apart side plates and are spaced from the edges of the plates to define a continuous belt guideway between the peripheral regions of the side plates. An endless belt is seated in the guideway in continuous contact with each of the rollers and functions as a crawler track when the truck wheels are out of contact with the stairs. The construction reduces resistance to belt movement from friction and inhibits jamming of the rollers and snagging of the belt.
