Abstract: A holding installation with an integrated closing sequence regulation is described for double doors comprising a leading door which is the first to close and a trailing door which then closes. The hydraulic door closer associated with the trailing door is provided with a signal generating device which is actuated in dependence on the piston position, and with an additional return flow passage for hydraulic fluid. The signal generating device controls the solenoid valve which holds the leading door by preventing the movement of hydraulic fluid contained in the door closer for the leading door, thus preventing movement of the associated piston.

Abstract: The mechanism of the invention can be mounted on and in contact with a frame. A spindle (2) is disposed within a shallow strip-like housing (1) parallel to an edge of a glazed sash of a window or door and a slider (3) displaceable on rotation of the spindle (2) is mounted on the spindle in order to drive a latching and/or deployment device for the glazed sash. The spindle can be adjusted by means of a knob-like handle (4) which is drivingly connected with the spindle (2) via gears (5, 6). A safety coupling (15 to 23) which limits the maximum achievable positioning force is arranged inside the handle (4).

Abstract: The cross-country ski binding has a plate which is arranged on the upper surface of the ski and is pivotable about a vertical axis located in the ball region of a boot. The plate is held in the central position by means of a latch device which releases to permit rotation of the plate relative to the ski on the occurrence of impermissibly high turning moments relative to the vertical axis and thus relative to the ball region.

Abstract: A safety toe unit for a ski binding has two sole retaining jaws (11, 12) which can pivot laterally outwards in opposite directions. A respective projection (13, 14) of a pressure member (19) acts on each of the sole retaining jaws at the front between the pivot axes (15, 16) and shoe retaining rollers (17, 18). The pressure member (19) is arranged for displacement in the longitudinal direction of the ski substantially in front of the sole retaining jaws (11, 12) and is urged in a rearward direction by a compression spring (21) which is braced against a housing (20) which in operation is secured to the ski. The two pivot axes (15, 16) which are spaced by a small transverse distance (A) from the central longitudinal plane (22) are tilted slightly inwardly towards the vertical and central longitudinal axis (22). The pressure member (19) has an extension (24) which extends forwardly inside the coil spring (21) and which is journalled by means of a ball-shaped head (24' ) in an elongate guide sleeve (26).

Abstract: A door closer the closing force of which can be adjusted is provided with a device for indicating the selected closing force. The device used to indicate the prevailing closing force is actuated in dependence on the adjustment of the spring which determines the closing force.

Abstract: Apparatus is described for regulating the closing sequence of double doors with at least one door closer associated with the leading door and a control arrangement which is actuated by the trailing door and which cooperates with the door closer of the leading door. The special feature of the apparatus lies in the fact that the control arrangement consists of a positioning member, which is arranged in the hinge edge region of the trailing door and is movable by the trailing door between first and second switching positions, and of a connection member which is connected to the positioning member. The connection member extends up to the door closer for the leading door and mechanically transmits the movement of the positioning member, to the closer for the leading door. The leading door end of the connecting member acts on a control member which blocks the closing movement of the door closer in one of the two switching positions of the positioning member.

Abstract: A door closing apparatus is described which embraces a unit for generating a closing force, a lever attached thereto via a releasable clutch for actuating the door and a controllable blocking device. The releasable clutch consists of a threaded connection which permits relative rotation between the actuating lever and the drive axle over a predetermined stroke. An abutment for frictionally locking the actuating lever is provided, with the frictional locking abutment becoming effective relative to the actuating lever at at least one end of the stroke. The holding force which sets in between the actuating lever and the frictional locking abutment is smaller than the holding force of the blocking device which blocks the unit for generating the closing force in the closing direction.

Abstract: The ski binding part consists essentially of a fulcrum part (1) which is affixed to the ski or displaceable thereon against a biasing spring (5) and on which a latch (2) is fulcrumed on a transverse axis (3) of the ski for the purpose of gripping the heel of the ski boot. On the side of the fulcrum (1) facing away from the boot, a thrust block (10) is displaceably guided on or in the latch and cooperates with a counterthrust member (13) integral with the latch. The longitudinal central axis (M) of the thrust block is disposed at a radial distance (a) below the fulcrum axis (3).

Abstract: A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally fixed toe restrainer (13) and generates, via a force deflection transmission, a longitudinal force which is dependent on the contact force which acts on the toe and which counteracts the spring force via a bar member (12). At least one lever (14) which is acted on by the vertically displaceably or pivotably arranged toe restrainer (13) acts on the same bar member (12) in the same sense with a release force which is dependent on the vertically upwardly directed force acting on the toe restrainer (13).

Abstract: A ski safety binding has a sole clamp 14, preferably formed as two sole clamp halves 14', 14", which is pressed by spring force against first and second abutment surfaces 12 provided on the binding housing 24 on respective sides of the central longitudinal axis 11. The first and second abutment surfaces 12 extend, at least in part, obliquely outwardly in the direction towards the ski boot in such a way that, during sideways release, the sole clamp 14 pivots about one or other of its points of contact 13 with the first and second abutment surfaces 12 and the associated point of contact 13 moves in the longitudinal direction of the ski in substantially exactly the same way as the vertical pivot axle 15 connecting the sole clamp to the release spring and draw rod assembly 31, 29 (FIG. 2). This means that the draw rod moves in a straight line without angular movement as in the prior art.

Abstract: An electrically releasable safety ski binding in which a measuring system determines the load applied to a skier's leg during skiing and a release mechanism incorporating an electromechanical converter such as a solenoid acts on a clamp device securing the ski boot to the binding to release the ski boot when the aforementioned load reaches a dangerous level. To prevent the binding becoming inoperative on failure of the electrical power supply the binding is equipped with an auxiliary release mechanism having a first inoperative state and a second operative state which can be selected either manually or automatically should the electrically operated release mechanism fail.

Abstract: A ski safety binding is designed to allow both a dangerous bending moment exerted about a transverse axis 15 through the weakest point of a skier's leg and a torsional moment exerted about a vertical axis 24 through the skier's leg to be detected and to be used to initiate release of the ski boot 54 from the binding when the bending and/or torsional loads approach dangerous levels. The binding basically consists of a sole plate 11 which carries a boot retaining system 56, 57 and which is mounted on a ski 12 for limited displacement in the longitudinal direction of the ski and for limited pivotal movements about a transverse axis 17 and a vertical axis 24. The sole plate is guided at its rear end for limited movement along an inclined guide 18 and along a transverse guide 21. This movement is resisted by respective hydraulic retaining means 28, 28'; 29, 29' which are however able to resiliently deflect once a predetermined load is exceeded.

Abstract: A ski safety binding is provided with a measuring system for determining the occurrence of a dangerous bending moment about a transverse axis 11 passing through the weakest point of the skier's leg lying generally somewhat above the ankle. In a first embodiment first, second and third measuring transducers 14, 15, 12 are strategically arranged between the sole of the ski boot and parts of a binding 33, 35 and the output signals from these measuring transducers are fed to a processing circuit 17 which computes the size of the bending moment about the transverse axis 11 and passes a release signal to an actuation device A to release the binding as soon as a dangerous level is reached. In a modification (FIG. 3) the ski boot is supported in the binding in such a manner that only two pressure measuring transducers are required. A variety of other embodiments are disclosed which show the use of ski bindings incorporating sole plates 24 (FIGS.

Abstract: A cross country ski binding has a support element attachable directly to a ski for engaging a forwardly extending boot sole extension, and is also provided with latching mechanism for latching the sole extension to the supporting element, under imposition of spring forces. The cross country ski binding may include spring biased detent members engageable into detent provisions provided directly on the boot sole extension, such that the forward part of the ski boot is automatically locked in position upon insertion of the boot sole extension into the support element. Preferred embodiments of the invention include those accommodating an axial movement of the boot sole extension into the support element and latching mechanism, as well as embodiments wherein the boot sole extension is placed downwardly over a pivot pin forming part of the holding mechanism. Also, certain embodiments of the invention include additional locking levers for locking the latching mechanism in a latched position.

Abstract: A ski brake of the type having a pair of brake arms and a boot plate which, when depressed, holds the brake arms in an in-use skiing position and which, when released, enables the brake arms to pivot to an in-use braking position under application of spring force, the brake arms partially overlying the top surface of the ski in the in-use skiing position, is improved with respect to the manner in which the ends of the brake arms are transversely pulled-in during movement to said in-use skiing position. According to a preferred embodiment, this improvement comprises the provision of control elements for achieving the transverse pulling-in of the braking arms that comprise right-angular shoulders on a bearing plate and diverging wire sections on an actuating part of the ski brake.
