Abstract:
An actuator assembly for hand-grippable devices, such as levers for a brake or clutch, triggers, scissor-action tools, etc. The actuator assembly is a lever having a rotation-restriction mechanism, such as a one-way bearing, mounted on a shaft, with a sleeve assembled over the rotation-restriction mechanism and shaft. As the lever is grasped by the fingertips and pulled toward the operator's palm, the sleeve rotates about the shaft axis, thereby allowing the lever to roll from the fingertips toward the base of the fingers near palm of the operator's hand, where the operator has greater strength and control over the lever. The sleeve is prevented from rotating in the reverse direction, so, when the operator releases the lever, the lever slides along toward the fingertips, allowing the operator to slow the motion as desired. The actuator assembly reduces fatigue and loss of control over hand-operated mechanisms.
Abstract:
The invention relates to a cable (4)-operated mechanism which is used to control a remote member and which is intended for civil engineering machinery or similar. The inventive mechanism consists of a casing (3) housing a control member comprising a proximal end forming a lever (1) which is articulated to the casing (3) and which is used to control the cable (4). The aforementioned control member consists of at least two abutting segments which are articulated to one another, namely: a proximal segment which forms the lever, and a distal segment comprising an elastically-deformable member which rests against the casing in order to form a lever control assist member.
Abstract:
Es wird eine Verstellvorrichtung für eine Bowdenzuganordnung in Form eines Hand- oder Spannschlosses beschrieben, welche ein Gehäuse (10), eine in dem Gehäuse (10) drehfest und axial beweglich geführte Gewindespindel (70), die mit einem Draht der Bowdenzuganordnung zu koppeln ist, und zwei Halbschalen (50), welche in dem Gehäuse (10) axialfest und drehbar angeordnet sind und sich mit der Gewindespindel (70) in Gewindeeingriff befinden, umfasst. An dem Gehäuse (10) befindet sich ein Ansatz (16) mit einer Öffnung (13), durch welche der Draht der Bowdenzuganordnung in axialer Richtung aus der Verstellvorrichtung geführt ist. Dem Ansatz (16) ist eine Hülse (30) zugeordnet, welche auf den Ansatz (16) formschlüssig aufzusetzen ist und eine Deformation des Ansatzes (16) bei einer Betätigung der Verstellvorrichtung verhindert.
Abstract:
A bicycle gear shifting system includes a gear shifting derailleur, a rotatable shift member to be rotatably carried by handlebars of the bicycle and connected to the gear shifting derailleur, and a hand attachment to be carried by a hand of a rider. The rotatable shift member and the hand attachment may each have respective mating surfaces for positively engaging one another to facilitate gear shifting by the rider and are readily releasable to permit the rider to change hand positions. More particularly, the mating surfaces may include pairs of corresponding recesses and projections. The pairs of corresponding recesses and projections may also be tapered. Furthermore, the mating surfaces may engage in superposed relation upon radial squeezing of the hand of the rider. According to another embodiment, the mating surfaces may engage in side-by-side relation upon lateral positioning of the hand of the rider.
Abstract:
A single handle mechanical brake system (14) is disclosed which comprises a container (20), a fixed axle (28) extending between two opposing sides of the container (20), a pivoting cam lever (26) mounted for rotation about the axle (28), the cam lever (26) also comprising a first pulley (30), a second pulley (24) which is actuated by a brake handle (10) and which interacts with the cam lever (26) to cause the cam lever to pivot about its axle (28), and a cable (16, 18) which extends over the first pulley (30) and has its ends secured to brake units (not shown); whereby the actuation of the lever (26) causes substantially equal pressure to the brake units at a multiple of the braking input pressure, the multiple being determined by the shape of the cam surface.
Abstract:
A brake operating device (30) is configured such that actuation of the brake lever (34) around the lever pivot (36) displaces the cable (38) in a direction transverse to the cable length toward the lever pivot (36), as the user is actuating the brake lever (34). This provides at least a 33 % increase in mechanical advantage over the actuation range of the brake lever (34).
Abstract:
A compensation device (7) is disclosed for a brake system operated by brake cables (4, 10), in particular a hand brake system for motor vehicles. An operating lever (1) is connected via a first brake cable (4) to a first brake (21) and a flexible tube (5) of the first brake cable (4) is supported on a lever-side support (6) and on the compensation device (7). A second brake cable (10) has an inner cable (9) which is hinged at one end on the compensation device (7) and connected at the other end to a second brake (22). The compensation device (7) has a transmission gear (20) and the first brake cable (4) has a split inner cable (3, 3a). One inner cable (3) is connected at one end to the operating lever (1) and at the other to an input of the transmission gear (20). The other inner cable (3a) is connected at one end to an output of the transmission gear (20) and at the other to the first brake (21).
Abstract:
The following techniques are implemented in order to provide a speed change system for a bicycle and a method of speed change for a bicycle, wherein the speed change operation can be performed almost without removing hands from a handle bar and no error is caused in the speed change operation to the low speed side or to the high speed side. That is, in a speed change system (1) for a bicycle constructed such that there is provided a speed change device including a front speed change gear (1a), a rear speed change gear (1b) and tubular operating members (4a, 4b) which are rotatably fitted on and supported by the outer peripheries of right and left gripping portions (3a, 3b) of a handle bar (2), said respective speed change gears being respectively operated by operating cables (T) pulled or delivered by the rotary operation of said respective tubular operating members, the upper surfaces of said respective tubular operating members (4a, 4b) are rotatably operated in the rearward moving direction, whereby said respective speed change gears (1a, 1b) are operated to the side of running at low speed.
