Abstract:
Overhead door assemblies having both interlocking and releasable guide assemblies, and guide track assemblies for use with same are disclosed herein. An overhead door track configured in accordance with an embodiment of the invention includes a first side portion spaced apart from a second side portion to define a channel or gap region therebetween. The first side portion has a first guide surface and a first retention surface. Similarly, the second side portion has a second guide surface and a second retention surface. In this embodiment, the first and second guide surfaces diverge outwardly from the gap region in a first direction, and the first and second retention surfaces diverge inwardly from the gap region in a second direction, opposite the first direction. An overhead door configured in accordance with another embodiment of the invention can include a first guide member configured to extend through the gap region and movably engage the first and second retention surfaces, and a second guide member configured to be removably engaged with the first and second guide surfaces.

Abstract:
A door opening and closing device for a slide door, which can be horizontally open and close the slide door by application of a light load and which can be constructed and maintained at low costs. The door opening and closing device has a transmission mechanism for converting through a lever (31) the amount of settlement of a tread plate (21) placed on floor surfaces at positions in front and back of the slide door (12), into a predetermined displacement amount. The tread plate (21) is weight-wise balanced such that the transmission mechanism and settlement of the tread plate due to the weight of an adjustment weight (W) causes the tread plate (21) to float through the lever (31). Up-down movement of the long transmission member (32) presses a drive rotation body (42) to an open door rail (41), and a component force of the pressing force allows the slide door (12) to be opened by application of a light load.
Abstract:
A window regulator rail, in particular for a motor vehicle, includes a mounting portion and a fastening bolt. The fastening bolt includes an attachment collar and first and second fastening portions that are arranged on opposite sides of the attachment collar. The fastening bolt is releasably and adjustably attached to the mounting portion of the window regulator rail in a predefined position by the first fastening portion. On the second fastening portion, a fastening member is arranged in a mounting position. The fastening bolt allows adjustment of the window regulator rail as needed.
Abstract:
A sliding door comprises a door structure and a guide rail. The door structure comprises a first surface, a second surface and at least one attachment assembly and defines at least one door aperture extending from the first surface to the second surface. The at least one attachment assembly comprises a first attachment member and a second attachment member. The second attachment member engages the first attachment member and extends through the at least one door aperture having at least a portion of the second attachment member extending beyond the second surface. The guide rail comprises a first contact surface and a second contact surface and defines at least one rail aperture configured to align with the at least one door aperture of the door structure. The second attachment member abuts the second contact surface of the guide rail. Methods of attaching a guide rail to a door structure are also provided herein. Vehicles are also provided.
Abstract:
A linear guidance system including a guide rail (1) and a carriage (2) which is guided displaceably on the guide rail by way of at least two ball bearings (3, 3′), wherein the ball bearings respectively comprise a plurality of balls (4) and a ball cage (5) and the guide rail (1) has running surfaces (9, 9′) and the carriage (2) has running surfaces (10, 10′) for the rolling movement of the balls (4) of the ball bearings (3, 3′), wherein the carriage (2) includes a profile member (11) which is substantially C-shaped in cross-section, wherein the running surfaces (10, 10′) are provided at the respective end portions (11′, 11″) of the C-shaped profile member (11) and the carriage (2) further includes a plate (12) which extends between the end portions (11′, 11″) of the C-shaped profile member (11) of the carriage (2) and is connected to said end portions (11′, 11″), forming a closed hollow profile.
Abstract:
A suspension-type storage unit that is particularly well suited for storing works of art or other hanging items in a space-efficient manner The storage unit includes a number of features that enable the storage unit to be moved between retracted and extended positions with a smooth, easy motion, without vibration, so as to protect and prevent damage to articles or items carried by the storage unit. The storage unit includes an overhead rail that defines a downwardly open guide slot and a pair of support surfaces located one on each side of the guide slot, in combination with a frame and at least a pair of trolley assemblies interposed between the rail and the frame for enabling movement of the frame relative to the rail along the guide slot. Each trolley assembly is formed with a head section that extends through the guide slot, and a wheel arrangement that is mounted to the head section. The wheel arrangement includes a pair of wheels between which the head section is located. Each wheel is engaged with one of the support surfaces of the overhead rail, for providing movement of the trolley along the rail. Each trolley assembly further includes a pair of arms that extend in opposite directions from the head section, and the frame is engaged with the pair of arms in a suspension-type manner.
Abstract:
A guide rail assembly for motor vehicle window lifters and a method for the production thereof. Two guide webs having protrusions formed thereon form a guide rail on a carrier plate made from a plastic material. The guide webs may be bent elastically inwards or outwards, enabling the driving element to be clipped on by pushing it on in the vehicle's transverse direction y and considerably simplifies production in an injection moulding process because the guide rail may be removed by elastically bending the guide rails such that a smaller number of sliders is required in the moulding tool. In one embodiment, there is also provided a driving element comprising a body of a first material and, securely held therein, sliding inserts comprised of a second material which material ensures a particularly good tribological pairing with the material of the associated guide web.
Abstract:
Two or more panels of a power-operated folding door are supported by a novel articulated arm assembly that ensures that the door closes tightly against a wall-mounted seal and easily opens. The articulated arm assembly includes a connector with two spaced-apart pivot points about which two adjoining arms of the assembly can rotate as the door opens and closes. The two pivot points allow the panels to readily fold up and store more compactly when the door is open. To provide an airtight seal where two leading panels come together at the center of the doorway, one or more control mechanisms coupled to the articulated arm assembly ensure that the leading panels overlap when the door is closed.
Abstract:
A ceiling driving unit for moving doors comprises a motor unit (12) arranged at the end of a running rail (11) for a door-dragging carriage (17). The motor unit has a driven axis (14) that engages a mechanism in the rail to transmit movement to the carriage and between the rail and motor unit there are mutual coupling means (26-27-28-29, 30-31-32-33) for connecting the motor unit to the rail and which are driven by manual rotation of the motor unit around the driven axis.
