The present invention relates to a piercing member protection device (9) which comprises a first, a second and a third cylindrical member (100, 200, 300). The first cylindrical member (100) is at least partly encompassed by the second cylindrical member (200), and the second cylindrical member (200) is at least partly encompassed by the third cylindrical member (300). The third cylindrical member (300) comprises a piercing member (400) having a piercing tip (401). A first locking arrangement (250) is arranged to enable or prevent the turning of the first and third cylindrical member, with respect to the second cylindrical member, while a second locking arrangement (350) is arranged to enable or prevent movement of the piercing member (400) along the longitudinal center axis A, so as to expose the piercing tip (401) of the piercing member (400). The piercing member protection device (9) provides a safe device which reduces the risk of accidental exposure of the piercing tip (401) and contamination for a user.

The invention relates to an endoscope having a shaft in which at least one working channel is positioned and having on the distal end of the shaft an endoscope head, such that the part of the working channel contained in the endoscope head can be rotated with respect to the related working channel by a Bowden cable that is mounted on a control handle on the proximal end by a collet. To configure an endoscope in such a manner that it ensures simple construction as well as a constantly even tension of the Bowden cable, it is proposed with the invention that the depth of insertion of a cable cord of the Bowden cable into the collet can be limited by a pressure element acting on the cable cord and collet.

It is an object of the invention to provide a wire retainer capable of easily mounting a wire on a retainer part and of simply fixing the wire retainer to a circuit board. A lower part of a long cylindrical body forms a fixed part which is fixed to the hole defined in the circuit board by a solder, and a base part of a retainer member is fixed to a substantially central part of the long cylindrical body. The base part has an extension part extending upward therefrom and a restriction part is fixed to an upper end of the extension part and extends downward along an upper portion of the long cylindrical body. A lead wire is inserted between the restriction part and the upper portion and retained by the retainer member.

A surface treating appliance, such as a vacuum cleaner, includes a handle, a surface treating head and a support assembly. The support assembly is rollably mounted to the main body for allowing the main body to be rolled along a surface. A linkage is provided between the main body and the surface treating head and arranged such that rotating the main body about its longitudinal axis causes the surface treating head to turn in a new direction. The support assembly may house a component of the appliance, such as a motor, and may accommodate a fluid inlet for receiving fluid flow and a fluid outlet for exhausting fluid. The handle may carry the main body of the appliance.

A knee walker includes a frame; a cushion; a front crossmember; two rear wheels; two front spindles and two front wheels each pivotally connected to one of the two front spindles. Positive steering is provided by a handlebar rotatably connected to the front end of the frame; a steering gear responsively engaged with the rotatably connected handlebar shaft; a steering arm actuated by the steering gear responsive to the handlebar; a steering rod connecting the steering arm and one of the two front spindles, so as to pivot one associated front wheel responsive to the steering arm; and a tie rod linking the two front spindles responsively to the steering rod.

A device for axially retaining blades on a rotor disk of a turbomachine, includes an annulus which is mounted via a radially inner edge in an annular groove of the disk and which presses against the roots of the blades mounted in grooves in the periphery of the disk, and an annular lock received in the annular groove of the disk to prevent the annulus from turning, the annular lock being turnable in the annular groove between an annulus-locking position and a position for mounting and dismounting in the annular groove.

The invention relates to a washer for a tube coupler device, the washer having an inner portion subdivided into a plurality of teeth with active portions having a free edge that defines an inside edge of the washer and that is arranged to penetrate into an outside surface of the tube, wherein the active portions are arranged so that the inside edge is substantially continuous. The invention also provides a method of making the washer and a coupler device.

In a cable clamp for fixing an electrical cable (8) that is connected to a connector, it is proposed to insert a clamping element (10) into a cylindrical cable receptacle (2) integrally moulded on the connector housing (1) such that it can be displaced by means of a pressure screw (20). Clamping fingers (13) that are integrally moulded on the clamping element (10) fix the electrical cable (8) extending within the clamping element (10) while guiding fingers (12) integrally moulded on the clamping element (10) prevent the clamping element (10) from turning.

An initially sealed storage apparatus carrying a material is provided. The present invention is directed to a mixing unit comprising a sealed container joined to a second container. When the second container is fully united with the sealed container, a seal in the sealed container is breached and the contents of the first container and the second container can be mixed. The seal is breached by a bushing enclosed within the sealed container or enclosed in a coupler between the sealed container and the second container which is advanced against the seal, and ruptures the seal when the second container is advanced into the coupler of the coupler portion of the sealed container.

An apparatus and method of securing a bicycle handlebar stem to the front wheel fork steerer tube with handlebar height adjustability and rotation of the handlebar and stem for easy storage. A steering assembly is provided where the handlebar stem is moveably fastened to the front fork steerer tube using a manually operated primary locking device and requiring a secondary action to allow for movement in the form of either height adjustment, or rotation, or both. The connection between the handlebar stem and the front fork steerer tube can be on the interior or the exterior of the front fork steerer tube. With the interior connection, the steerer tube can be elongated to extend above the top of the headset bearings where it is fitted with a collar for clamping onto the internally mounted stem. The handlebar stem and fork steerer tube are fitted with corresponding octagonal or other cross sectional shapes, or a safety tracking system. For bicycles equipped with handlebar stems which clamp to the outside of the fork steerer tube, the handlebar stem is equipped with a safety lock and can be rotated for storage with no height adjustability.
