Abstract: A high-speed stroke-type moving device for an elongate flexible body having at least one supply line. The device has a guideway for guided displacement of the body, having a spiral portion, in which at least part of the body is compactly accommodatable in a plurality of spaced tracks which are not in mutual contact and extend substantially spirally inwards. The invention provides that the body has a line guideway for the at least one supply line. According to the invention, the line guideway here has a first sub-portion which is guided in the spiral portion and an unguided second sub-portion having a first end which is connected at the end to the first sub-portion and a second end which is connected at the end to a rotary feedthrough for the at least one supply line. A corresponding device having an energy chain is furthermore disclosed.

Abstract: A ball-bearing control cable comprising an outer sheath surrounding a central blade. The outer sheath comprises a central portion extending between two endpieces. Each endpiece comprises a tubular central body that surrounds the central blade, each central body extending from a proximal abutment secured to the central portion towards a free distal abutment, each abutment of an endpiece projecting from the central body of the endpiece, each endpiece including a resilient system interposed around the central body of the endpiece between an abutment of the endpiece and a ring, the resilient system of one endpiece being arranged between the distal abutment and the ring of the endpiece, and the resilient system of the other endpiece being arranged between the proximal abutment and the ring of the other endpiece.

Abstract: A brake adapter for a bicycle brake is provided with a bent, rigid tube including a plurality of transverse holes communicating with interior of the bent, rigid tube; and a plurality of rollers rotatably disposed in the transverse holes respectively. Both ends of each transverse hole are smaller than both ends of each roller respectively.

Abstract: Conventional linkages between bicycle handlebar-mounted controls and rear brakes and gears are unable to accommodate unlimited rotation of the handlebars as is required on some so-called “freestyle” bicycles. A prior attempt to solve the problem employs a linkage comprising a bearing having two parts that are relatively rotatable about an axis. However this proposal is unable to handle situations where there are two or more mechanisms to be controlled e.g. a rear brake and a gear. The problem is solved by using multiple bearings (15, 16, 17) that share a common axis (X-X) of rotation but are located at different radial positions with respect to the axis. This avoids interference between the different linkages and makes it possible to locate the linkages around a stem on which the front wheel fork of the bicycle is mounted. A possible suitable location may be within a head tube of the bicycle frame. The invention is not limited to use with bicycles and can be employed in robotic and other machines.

Abstract: A brake level for a bicycle is assembled and disassembled by a locking method. After assembly of the brake level, a brake cable can be assembled to the brake level just by means of a single through hole. By such arrangements, the assembling cost of the brake level can be reduced, and the brake level can be assembled and disassembled repeatedly.

Abstract: A safety cable system for a fitness device including a resistance load and a user interface device. A redundant cable apparatus connects the resistance load to the user interface device for lifting the resistance load by a force applied to the user interface device. The redundant cable apparatus comprises two cables extending in redundant cable paths between the resistance load and the user interface device. The two cables can share the resistance load or one of the cables can be dormant until failure of the other cable.

Abstract: A pull cable can restrain cable curvature by the use of cable links configured to provide a limit to a range of an angular relationship between neighboring cable links. By limiting the angular variation between links, a minimum radius of the pull cable can be provided. The cable links can inhibit kinking of the inner cable by restricting the cable from reaching a small radius that could induce kinking.

Abstract: The present invention is a computer controlled display device. In one embodiment, the display device includes a flat panel display having an input for receiving display data. Additionally, a moveable assembly may be coupled to the display. The moveable assembly may provide at least three degrees of freedom of movement for the flat panel display device. Additionally, the moveable assembly may have a cross-sectional area, which is substantially less than a cross-sectional area of a display structure of the flat panel display.

Abstract: A pull cable system, includes a cable for transmitting a tensile force, a flexible tube for accommodating the cable, and a casing surrounding the tube for absorbing a pressure force. The casing is composed of a plurality of form-parts so joined to one another as to form a continuous axial passageway which is defined by an inside dimension. The form-parts are so configured that abutting end faces between successive form-parts have a complementary configuration to thereby enable a disposition of the casing along an arcuate path, with the tube being defined by an outside dimension corresponding to the inside dimension of the passageway.

Abstract: A rolling bearing for journalling an outer machine component (12) for rotary movements in relation to an inner machine component (13). For connection to at least one of the machine components, the bearing comprises corresponding outer and inner main elements, respectively, in the shape of a helical spring (14/15), which is wound to form parts (16/22) supporting rolling surfaces for the rolling bodies (17) of the bearing, which rolling bodies are arranged in an annular raceway. The spring is wound from said supporting part so that it forms a connection part (19/24) in at least one axial direction. These connection parts are arranged to connect and join with further operative parts of the bearing. Examples include parts for connecting the supporting part in question for said rolling surface with further such parts to form a bearing with several rows.
