Abstract:
A finger protection device (2) for a door or window comprising attachment means (5) for attachment to either a door or window or a corresponding door/window frame, which door or window is arranged for relative movement with respect to its frame, and abutment means (4) connected to the attachment means (5) and biased towards an opening created by movement of the door or window out of its corresponding frame.
Abstract:
The invention concerns a damping device for damping the kinetic energy of movable cabinet components, which has a first damping element with a first cylinder that has a first piston, which slides lengthwise in it, and at least one more (second) damping element with a second cylinder that has a second piston, which slides lengthwise in it. Both damping elements are located one behind the other in a serial arrangement and form an integral system. The invention is characterized by the fact that each of the two damping elements are each designed as pneumatic (air) dampers, and a compression chamber and an expansion chamber respectively contain variable volumes; whereby, the damping effects of the damping elements are affected by the guide canals, which control the air distribution and air flow within and between the compression chambers and/or expansion chambers.
Abstract:
An automatic door closer for a sliding door. The closer has a reel with a cable extending around a pulley on the end of the rod of a return mechanism. In preferred embodiments, the return mechanism is an oil dammed gas spring or a magnetic spring. A spool rotates on a common shaft with the reel and is wound with a flat tape which is attached to the door frame. The reel, spool, return mechanism and cable are attached to the door so that application of an opening force will cause the cylinder rod to retract. Upon release, the stored energy will cause the rod to extend, rotating the reel and spool to wind the tape onto the spool applying a controlled rate closing force. The spool has a core with a greater diameter than the core of the reel so a mechanical advantage exists between the spool and reel and friction is reduced.
Abstract:
A retractable door system for returning to a nearly closed position a door that has been opened having: a catch knob secured to a doorframe; a housing secured to a door; a retractable cord anchored within the housing at one end and having means for attaching to the catch knob at an opposite end; and a cord retracting means located within the housing for retracting the cord within the housing. The retractable door system may optionally further have a pad on the portion of the housing contacting a doorframe when the door is placed in a nearly closed position or a pad on the portion of the housing contacting a door or means for adjusting the tension of the retractable cord.
Abstract:
A multi-function door stop is provided comprising a first vertical plate for mounting to a wall and a second horizontal plate affixed to and extending outwardly from the first plate. A hollow elongated tube extends outwardly in a direction away from the second plate in a normal position substantially perpendicular to the first plate. An extension member is interposed between the second plate and the elongated tube, the extension member being fixedly secured at one end to the second plate. The elongated tube is pivotally connected to the other end of the extension member permitting adjustment of the tube to a ninety degree impact with the door. A means is associated with the extension member for releasably locking the tube in its normal position. In use, the door stop remains in its normal position until the elongated tube is struck by an object, such as a vacuum cleaner or mop. The impact releases the tube from its locked position and allows it to swing about its pivot point to an out of the way position substantially parallel to the wall.
Abstract:
A damping device for movable furniture parts, such as doors or drawers, includes a cylinder filled with a free-flowing medium which is compressed by a piston which has a spring applied to it in its extended position. In order to provide a damping device of this type of smaller length, the cylinder includes a telescopic cylinder having at least two stages. A pressure spring is clamped between the bottom of the outer cylinder of the last stage and the piston of the first stage.
Abstract:
This invention offers advantages over the prior art by providing a simple, inexpensive mechanism and method for reducing the shock load on the drive of a rotary or linear actuator when the motion of the actuator output shaft is slowed, even to the point of stopping. This is referred to as bringing the actuator to a “soft stop.” This invention uses a single spring wherein the spring may be a torsion, ribbon or compression spring. The mechanism generally includes a spring, a spring cup and a drive cup. When the motion of the output shaft is slowed or reaches its limit of travel, the spring begins to store energy and brings the drive cup to a soft stop.
Abstract:
A device (10; 10a) for guiding and limiting the travel of a sliding door element (1) has a receiving and stop element (12; 12a; 12b; 12c) which cooperates by positive engagement with a centering element (11; 11a). It is proposed that the centering element (11; 11a) be embodied with a wedge-shaped portion (18; 29) and that the receiving and stop element (12; 12a; 12b; 12c) be embodied with a V-shaped portion (19; 40). The device (10; 10a) is especially simply embodied and requires only little effort for assembly.
Abstract:
There is described a balancing element for a flap opening especially at an automobile, with two end points, which are adjustable relative to one another in the principal direction of the element, and comprising two draw yokes (15) which are operatively connected together and which are enclosed by a tension spring (20) snugly embracing them and having its end points fixed near the end points of the draw yokes (15).
Abstract:
A rattle-free peripheral interface between a housing and a top latched thereto including at least generally vertically extending, integral, resilient members which are resiliently deformed when the top is latched to the cover, with the integral resilient members providing the sole contact between the opposed peripheries of the top and of the housing. A first form of resilient member includes a pair of oppositely extending, diagonal legs extending down from the top and terminating in feet which resiliently contact rigid shelves or facing areas on the opposed housing (FIG. 4), the housing having a castellated, interdigitated interface with the resilient member. A second form of resilient member includes a vertically extended, thin member on the underside of the top, which is resiliently deformed and in contact with an opposed rigid shelf when the top is latched onto the housing (FIGS. 5A and 5B). A pair of opposed, pivoting latching arms are integrally provided at opposite ends of the top, with each having a fixed restraint limiting the outward movement of the top of the arm, preventing overstressing of the latching system including the integral junction between the arm and the top. With the contact between the top and housing being limited to the resilient members, the balance of their opposed peripheries being generally out of contact, the top has a relatively rattle-free interface with the housing avoiding the need for, for example, a foam gasket.
