Abstract:
An improved guide device (10) for the opening and the support of furniture doors suitable for guiding and supporting the movement thereof both during opening and closing phases, comprising a container body (11) of substantially rectangular shape attached on the inner face of a lateral shoulder (12) of a frame of an item of furniture (14) provided with a door (16) fall-front openable via at least one hinge (18) attached to the frame of the furniture (14) and operatively connected to the container body (11) by means of a cable (20) attached to said door (16) via a fastening element (22) constrained to an inner face of the same door (16), said device which likewise comprises a body-slide (48) sliding inside said container body (11) and integrating means roto-translating with respect to a cogged profile or rack (32) of the container body (11) for a movement of said body-slide (48) and an unwinding/winding of said cable (20) in contrast to or assisted by a return spring and/or by damping means.
Abstract:
The invention relates to devices for opening/closing sliding doors. The opening/closing mechanism comprises at least one guide track with at least two guideways disposed therein, said track being fastened to the ceiling and/or to the top of a door aperture and/or being integral therewith, at least two carriages disposed in the track with the ability to move horizontally, thereby enabling the movement of an outer door and an inner door to which they are connected, a door handle, and movable pulleys fastened to the inner door and situated in the top part thereof, which are connected to stationary pulleys situated at the ends of the guide track to form, together with a cable or cord, a pulley and cable system that is connected to the leaf of the outer and inner doors via fastenings of the stationary pulleys/rollers and fastenings of the cable/cord to the door so that when the sliding doors are moved in a horizontal position, the speed of movement of the outer door is greater than the speed of movement of the inner door. The technical result is a reduction in noise when the device is in operation, and the elimination of shocks and deformations.
Abstract:
The invention relates to a sash for laboratory fume hoods, having two telescopically movable slides, a front slide (4, 4') and a rear slide (8, 8'), of which one slide (4, 4') is connected to a counterweight via a pulling means (6, 6'). The front slide (4, 4') is suspended at one end (5) of the pulling means (6, 6'), of which the end which is directed away from the end (5) fixed to the slide is fastened on the counterweight. The rear slide (8, 8') is supported by elements (10, 9) which are in operative connection with the front slide (4, 4') such that the rear slide (8, 8'), when the front slide (4, 4') moves, moves in the same direction as the front slide (4, 4') and over half the distance of the front slide (4, 4').
Abstract:
A rectangular one-piece garage door (404) has rigid horizontal upper and lower rails (406) (408) and rigid vertical first and second side rails (410) (412). A small door (416) is mounted in the garage door. A track assembly has horizontal first and second upper tracks (420) (422). The track assembly has vertical first and second lower tracks (424) (426). An arcuate first intermediate track (428) couples the first upper track and the first lower track. An arcuate second intermediate track (430) couples the second upper track and the second lower track. First and second upper hinged brackets (436) (438) are secured to the garage door adjacent to the upper rail. First and second lower brackets (440) (442) are secured to the garage door adjacent to the lower rail. Rollers (448) are each coupled to one of the brackets and rotatably received within one of the tracks for guiding the movement of the garage door between a closed lower orientation and an open raised orientation.
Abstract:
Die Erfindung betrifft ein Tor (1) welches ein Antriebssystem umfasst, mittels dessen ein seitlich in Führungsschienen geführtes Torblatt (2) zwischen einer Öffnungsstellung und einer Schließstellung bewegbar ist. Eine Gewichtsausgleichseinrichtung umfasst eine Seileinheit (8) und eine Federeinheit (9) an einer oder jeder Torblattseite sowie eine der Seileinheit (8) zugeordnete Seilspannungs-Ausgleichseinrichtung (12). Die oder jede Seilspannungs- Ausgleichseinrichtung (12) ist sicher gegen Seilbruch. Die oder jede Seileinheit (8) besteht aus einem Seil (10), welches an der ortsfest gelagerten Seilspannungs-Ausgleichseinrichtung (12) umgelenkt ist, so dass zwei in Abstand zueinander verlaufende Seilstränge erhalten werden. Die freien Enden des Seils (10) sind zusammengeführt und am Torblatt (2) befestigt. Alternativ kann die Seilspannungs-Ausgleichseinrichtung (12) am Torblatt (2) befestigt sein. Dann sind die freien Enden des Seils (10) ortsfest gelagert.
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 mechanism and method for operating a track-mounted door is disclosed. The mechanism includes a pair of side drums that are connected by first cables to the bottom of the door. The side drums are coaxially mounted on a shaft for simultaneous rotation with a pair of cable drums. The cable drums are connected to high pressure gas struts by second cables. Each second cable is carried around a shiv wheel that slides along a guide track as the second cable moves. Each shiv wheel is operatively connected to one of the gas struts. As the shiv wheel moves along the guide track toward the cable drum, the gas strut is charged. As the shiv wheel moves away from the cable drum, the gas strut is discharged. A standard electric motor and screw driven lift-arm is used to initiate the opening and closing of the door. The charged gas strut stores sufficient energy to overcome friction and gravity to assist the electric motor and lift-arm to open the door.
Abstract:
A cord tensioned by a spring supports the sash of a hung window in a stationary position while the sash is maintained tilted into a building for cleaning the window's external surface. The cord pulls a pulley attached to the spring, which extends as the sash is further tilted. A tubing houses the spring and pulley and provides a stop that limits the maximum tilt of the sash.
Abstract:
A window having a window panel that slides in a frame and at least one balancer that is secured to the window panel is disclosed. The window is of the tiltable hung type having a vertical operating position in which the balancer slides with the window panel in the frame and a tilted position in which the balancer remains secured to the window panel. The balancer includes an extensible member having a first end operatively coupled to the balancer and a second end operatively coupled to a frame so that the balancer can exert a force on the window panel to assist against the force of gravity when the window panel is in the vertical operating position. A method of constructing a tiltable hung window with a balancer secured to the window panel is also disclosed.
