Abstract: A clamp-type locking mechanism has a driven element rotatably arranged with respect to a holding element and having ramps which together with a track of the holding element define clamping gaps for receiving spring-loaded clamp rollers. An adjustment element is swingable to a limited extent with respect to the driven element and provided for rotation in unison with the driven element, with the adjustment element having engagement members for moving the clamp rollers out of their clamping gaps. Located between the driven element and the holding element is a friction device for transmitting a friction moment. In order to maintain a correct friction moment during wear of the friction device, a spring mechanism is provided by which the friction device is biased with its friction surface against the holding element.

Abstract: A clamp-type locking mechanism includes a housing (1) with an inner cylindrical clamping surface (3) and with driving elements (5) and driven elements (4) positioned concentrically therewith. The driven element (4) is provided with clamping ramps (23, 24) facing the clamping surface (3), which have arranged thereon clamping roller pairs formed of two clamping rollers (25) successively placed along the circumference. Both clamping rollers (25) are spring-biased by an interposed spring element (26, 30) in direction away from each other towards the clamping surface (3) and the clamping ramp (23, 24), with the driven element (4) being provided with stops (28) for claws (19) of the driving element (5).

Abstract: A free-running roller coupling transmits in both directions of rotation a torque between two structural members. This coupling has an outer ring in which clamping tracks are formed by recesses. An inner element has a cylindrical clamping track. Pairs of clamping rollers, prestressed by a pressure spring against the ramp-like end of each clamping track, are arranged between the clamping track of the inner element and the clamping tracks of the outer ring. An unblocking arrangement has comb-like carriers that extend through slots in an edge of the outer ring, which carriers can unblock the rollers while allowing the outer ring to be driven by a switching sleeve.

Abstract: A locking element freewheel comprising an outer race ring (1) and an inner race ring (2) with cylindrical and mutually concentric locking surfaces (7,8) between which tiltably suspended locking elements (5) are guided in a cage (6) wherein the central portion of the locking surfaces (7,8) of the outer race ring (1) or inner race ring (2) has a smaller or larger diameter than the ends thereof. If, due to differing wall thicknesses, the race rings (1,2) have differing rigidity, the edge region of highest rigidity of the locking surfaces (7,8) of the outer race ring (1) and/or inner race ring (2) has a larger or smaller diameter and by such a profiling of the locking surfaces, an overloading at the edges of the locking elements is prevented.

Abstract: The invention concerns a switchable locking element freewheel with two concentric cage rings and locking elements lodged in pockets thereof, the cage rings being movable relative to each other for switching the freewheel. In order to make such a freewheel basically operable in two opposing directions and to provide simple switchover facilities herefor and also for cases in which switchability is required only in one direction, the relative movement of the two cage rings serving to switch the freewheel is an axial displacement which, with a view to any further embodiments of the freewheel, can be converted into a rotary movement.

Abstract: An overrunning clutch comprising clamping rings arranged concentrially in each other with mutually facing clamping paths between which clamping elements are arranged and a switching member arranged equiaxially with one of the clamping rings which is designed to have a variable diameter, acting on this clamping ring by utilizing a wedge-surface effect so that a rotation of the switching member relative to the clamping ring with variable diameter causes a change in the distance between the clamping paths, characterized in that the clamping ring with variable diameter is divided by at least one axial slit and pre-tensioned by at least one spring to oppose the change in distance between the clamping paths which can be effected by the switching member.

Abstract: An overrunning clutch comprising a clamping ring provided with clamping ramps and spring-loaded clamping rollers housed in pockets of a cage and associated with the clamping ramps, the clutch being switchable from a first indexing position into a second by rotation of the cage with respect to the clamping ring. The cage is characterized by either directly or with the help of an intermediate member on the one hand, and the clamping ring with projections and recesses on the other, engage in each other in such a way after the fashion of a screw thread that when the cage or the intermediate member, as the case may be, is axially displaced, the cage executes a movement of rotation with respect to the clamping ring.

Abstract: A cage for an overrunning clutch with a metallic outer race accommodating concentrically a metallic inner element and having in a cage arranged between the outer race and the inner element camming elements retained under the action of springs in camming contact with the surfaces of the outer race, on the one hand, and of the inner element, on the other hand, the cage being made of injection moldable or castable polymeric material and having pockets for the camming elements defined by crossbars and at least one end ring connected therewith, at least one circumferential surface of the cage cooperating in the form of a sliding bearing with a cylindrical surface of the adjacent structural part (outer race and/or inner element), characterized in that the cage (1,15,22,30,39) is provided at least in the area of the end ring (4,18,23,33,45) with an annular metallic reinforcement shield (13,19,20,26,27,34,35,47) connected to the cage (1,15,22,30,39) in a form-fitting manner especially through injection-molding around

Abstract: In a pen holder device, a pen holder body (3) contained in a support body (2) is pivotable between an operational position, which is slightly inclined from the perpendicular, and a generally horizontal readiness position, wherein an acute angle exists between the operational position and the readiness position. Bearing shoulders (15) provided on opposite sides of the pen holder body (3) rest with little friction upon support surfaces (12) having evenly curved surface areas. The center of gravity (21) of the pen holder body (3) alone is below the bearing shoulders (15) and the common center of gravity (20) of the pen holder body (3) and a writing instrument (4) inserted in it is above the bearing shoulders (15).

The sealing element (4) has a bearing area for contact with a writing tube (12) that is convex curved in the direction toward said insertion opening of the stand (1, 2) and is deformable away from said insertion opening by contact with the tube. The stand further is characterized by an elastically deformable restraining element (5) which is provided between said sealing element (4) and said insertion opening, and adapted to engage against an inserted tubular writing pen (10, 11, 12).
