Abstract:
A convenient cover opening and closing method, system, and apparatus are described. A cover grasper, adjustable tension, an anchor, and a stabilizer provide the necessary torques so that a cover opens and closes in a controlled smooth manner. Moreover, the apparatus and system may be conveniently removed from and secured to the cover's container, may be secured in a more permanent fashion to the container, or components of it may be secured on the container while others are not.
Abstract:
The present invention provides for apparatus and methods for operating a garage door. An embodiment of an operating assembly for a door includes a shaft, a graduated drum, and an energy storing member. The shaft is coupled to the door such that the shaft rotates in a first direction as the door is opened and rotates in a second direction as the door is closed. The coupling of the shaft to the door is typically accomplished by a cable. The graduated drum is coupled to the shaft and the energy storing member is coupled to the graduated drum by another cable. The energy storing member is arranged such that the energy storing member stores energy as the door is closed and releases stored energy as the door is opened to assist in the raising and lowering of the door.
Abstract:
A horizontally extending screen door system having balancing cords that pull in a direction that opposes the force on a handle by the screen exerted by the wind up mechanism of the screen.
Abstract:
A resistance mechanism suitable for applications such as resistance exercise equipment, cable reels, garage doors and other equipment requiring a resistive force. Resistance packs (26) include circular rims (28) and central hubs (30) connected by deformable spokes (32). The packs (26) are stacked in pairs with the rims (28) in each pair pinned together and the hubs (30) ratatable relative to one another. Each hub has a spline (34) connection with the hub of the next resistance pack in the adjacent pair. This provides a series arrangement of the resistance packs (26) which allows a long extension of the actuator with the spokes (32) of each pack being deformed only slightly. A spiral pay out pulley for the cord assists in avoiding varying resistance with extersion of the cord. The mechanism includes a preload system for applying a preload force to the resistance packs and a visual indicator for indicating the level of the preload force. An alternative construction involves forming the resistance packs in a single base having a pair of the resistance devices housed together. The devices may include arms connected by peripheral portions to provide loops that are looped around walls on the base to avoid a need for a bonded connection of the arms to the rims.
Abstract:
La porte basculante comporte un ouvrant (1) et des moyens de commande d'ouverture et de fermeture agencés pour déplacer le bord inférieur (12) de l'ouvrant selon un plan de fermeture vertical et pour déplacer le bord supérieur (11) de l'ouvrant selon un plan d'ouverture horizontal ou oblique. Les moyens de commande comportent des liens souples (2, 3, 4) de transmission d'effort arrangés selon un circuit horizontal et un circuit vertical, l'un étant un circuit maître et l'autre un circuit esclave, le circuit horizontal étant situé dans le plan d'ouverture et connecté au bord supérieur (11) de l'ouvrant, et le circuit vertical étant situé dans le plan de fermeture et connecté au bord inférieur de l'ouvrant, un moyen moteur (5) étant agencé pour entraîner en défilement le circuit maître, et les deux circuits étant reliés par un tiroir (6) mobile transversalement, préférentiellement situé dans une zone au-dessus de la porte, où les deux circuits comportent des segments parallèles, le tiroir portant des éléments de renvoi des liens agencés de manière qu'un déplacement provoqué du ou des liens (3, 4) d'un des deux circuits entraine un déplacement simultané asynchrone du ou des liens (2) de l'autre circuit en répartissant automatiquement les efforts exercés par les liens respectivement sur le bord supérieur et sur le bord inférieur de la porte.
Abstract:
A plug (1) for use with a counterbalancing system (3) of a cable-operated door (5). The plug (1) includes flange and collar portions (13,15), the flange portion (13) being connectable to a mounting component (7) of the counterbalancing system (3) in order to allow a torque transfer from a torsion spring (9) to the mounting component (7), and the collar portion (15) being configured for winding into a given end (17) of the torsion spring (9), the collar portion (15) having opposite first and second extremities (19,21), and an outer surface (23) extending between these extremities (19,21), the outer surface (23) of the collar portion (15) being provided with a plurality of threads (25) and a plurality of corresponding recesses (27) each being defined between a pair of adjacent threads (25), each recess (27) being configured for receiving therein a single coil segment (11a) of the torsion spring (9), and being further shaped and sized for preventing another coil segment (11b) of the torsion spring (9) from embarking onto said recess (27).
Abstract:
Eine Faltfassaden- oder Faltmarkisenanordnung, umfasst zumindest zwei Fassaden- oder Markisenelemente (12A, 12B), von denen ein erstes Fassadenoder Markisenelement (12A) um eine Achse (12A' ) schwenkbar an einem Gebäude (1 ) befestigt ist, und von denen ein zweites Fassaden- oder Markisenelement (12B) um eine verlagerbare zweite Achse (12B' ) schwenkbar gehalten und entlang von Führungen (16A, 16B) verlagerbar ist mittels eines Antriebsgliedes (18), und eine erste Ausknickkante, (15A) des ersten Fassaden- oder Markisenelementes (12A) mit einer zweiten Ausknickkante (15B) des zweiten Fassaden- und Markisenelementes (12B) unter Ausbildung eines Ausknickgelenkes (14A, 14B) schwenkbar verbunden ist und losgelöst von den Führungen (16A, 16B) im Sinne eines Ausknickens quer zu der Fassade und bewegbar ist und ferner umfassend mindestens ein Ausknick- und/oder Verriegelungsmittel. Ein sicherer Betrieb wird dadurch erreicht, dass mindestens ein schwenkbares Betätigungselement in Gestalt eines Ausknick-, Heranzieh- und/oder Verriegelungsmittels vorgesehen ist.
Abstract:
A bottom bracket (12) for an overhead garage door (10) having a spring tension assisted lift system. The bottom bracket (12) has protrusions (22) that interlock with mating slots (46) in the stile (15) of the garage door bottom panel (14) thus preventing the bracket (12) from detaching from the garage door (10) when the bracket is attached to the spring (18) under tension, even if the bracket fastening screws (33) are removed.
Abstract:
A window frame comprising a plurality of elongate frame members defining a frame opening for receiving a window for closing the frame opening. At least one of the elongate frame members having a longitudinally extending recess; and a slide mechanism received within the recess, wherein the slide mechanism comprises a first track fixed within the recess and a second track movable within and along the recess and coupled to the first track via a rotary coupling member such that movement of second track along the recess causes the rotary coupling member to rotate, wherein the second track is arranged to be coupled to the window when the window is received within the frame opening to enable the window to slide relative to the frame.
