Abstract:
A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.
Abstract:
A hinge device for a door of a refrigerator, etc. moves the center of rotation of the door by interlocking with the opening/closing operations of the door, while stabilizing the opening/closing operations without any hindrance such as rattling.The hinge device comprises: a shaft member (105) which is mounted on a refrigerator main body (102) and comprises a hinge pin (153); a bearing member (107) which is mounted on a door (103) and comprises a long hole (107b) which is in contact with the hinge pin (153) to be relatively movable or relatively rotatable with respect to the hinge pin (153); and a cam (109) which is installed on the hinge pin (153) and constitutes a cam unit (C) by contacting a cam follower (107d) of the bearing member (107). The contact between the hinge pin (153) and the long hole (107b) and the contact between the cam (109) and the cam follower (107d) are constantly maintained without being interrupted by the opening/closing angle conditions of the door (103) respectively, and the contact between the hinge pin (153) and the long hole (107b) cooperates with the cam unit (C) by interlocking with the opening/closing operations of the door (103), thereby guiding the opening/closing operations of the door (103).
Abstract:
A door hinge has a first hinge plate connected with a second hinge plate that is adjustably disposed in a hinge accommodation element, so as to pivot, with a pin on a hinge roll. The hinge accommodation element has a front part and a rear part, and the second hinge plate is guided in the hinge accommodation element so as to move in the vertical direction, and can be tilted in the horizontal direction, relative to the hinge accommodation element, with an adjustment screw. The front part and the rear part of the hinge accommodation element are connected by a connection screw, and the second hinge plate is clamped in place between the front part and the rear part, so that it cannot be displaced in the vertical direction, after the connection screw has been tightened. A hinge system can be formed by three of these door hinges.
Abstract:
Provided is a door opening and closing device that includes: a main opening and closing device body attached to a housing; a mounting member attached to a door; an arm pivotably provided to the main opening and closing device body, the arm applying force to the door via the mounting member in an opening direction and/or a closing direction; a slider provided to the main opening and closing device body to be slidable in one direction; an urging unit for urging the slider in the one direction; a transmission mechanism for transmitting urging force of the urging unit to the arm; and a door restraint link pivotably linked to the arm at a position away from the center of pivot of the arm, pivotably linked to the mounting member, and slidably linked to the main opening and closing device body so that the door moves in a certain manner.
Abstract:
The invention relates to a three-dimensional adjustable hardware system. According to the invention, at least one of the hardware bodies (18) comprises at least one guide pin (28) for the purpose of adjusting the hardware system (10) in the z-direction and the housing, in which the at least hardware body is arranged, comprises at least one threaded pin (30, 32), wherein the guide pin (28) and thereby the hardware body (18) are moved relative to the housing in the z-direction when the threaded pin (30) is rotated. For the purpose of adjusting the hardware system in the x-direction at least one of the hardware bodies (16) accommodates at least one adjusting pin (34), which can be moved along the y-axis located in the xy-plane, and at least one surface (36, 38) of the adjusting pin (34) which is inclined with respect to the y-axis interacts with at least one sliding pin (40, 42), the movement of which along the x-axis located in the xy-plane being restricted by the housing (12) accommodating the at least one hardware body (16), and so the hardware body (16) can be moved relative to the housing (12) in the x-direction by adjusting the adjustment pin (34). For the purpose of adjusting the hardware system in the y-direction at least one housing (14) and the hardware body (18) arranged in said housing have at least one sliding guide (44) extending along the y-axis, along which the hardware body can be moved relative to the housing (14) in the y-direction.
Abstract:
A slip resistant hinge system for doors and, in particular, frameless glass doors, is provided. The hinge includes a dovetail-shaped central raised portion that minimizes or prevents the possibility of the glass slipping when secured to the hinge. The dovetail-shaped central raised portion can be designed as part of the hinge or can be created by inserts positioned around the central raised portion of the hinge. In operation, a corresponding dovetail-shaped opening is cut into the door for receiving the hinge.
Abstract:
An openable roof window includes: a window panel configured to be slidable along a guide rail to selectively open and close an opening in a roof and tiltable relative to a base frame; a slider having a pin and driven by a drive device to slide along the guide rail; an engagement structure that selectively engages the slider with the window panel such that they are unmovable relative to each other in a direction along the guide rail; and the engagement structure includes a stay fixedly secured to the window panel and having a cam groove formed therein, the cam groove engaging the pin of the slider and having a shape defined such that, when the engagement structure does not engage the slider with the window panel, the window panel is caused to tilt as the slider moves relative to the stay as a result of sliding of the slider along the guide rail.
Abstract:
An actuating drive (5) for moving a moveable furniture part (3), comprising: at least one moveably mounted actuating member (7) for moving the moveable furniture part (3); a spring device (11) for subjecting the actuating member (7) to force; an adjustment device (13) by means of which a force of the spring device (11), which force acts on the actuating member (7) can be adjusted; wherein the adjustment device (13) has an adjustment screw (16) having a thread (17), wherein the force of the spring device (11), which force acts on the actuating member (7), can be adjusted via a screw nut (12) which is mounted displaceably along the thread (17), wherein at least one spring element (26) is provided via which the screw nut (12) can be subjected, at at least one end region of the adjustment screw (16), to a force directed away from said end region.
Abstract:
A hinge for doors of appliances includes a movable arm connected to a door of the appliance, pivoted on a frame to rotate about an axis to make the door movable relative to the frame between closed and open positions. A control shaft extends longitudinally parallel to the axis and is connected to the frame. A sleeve attached to the movable arm extends parallel to the axis. An elastic element is contained inside the sleeve to generate an elastic force for closing the door. A mechanism drives the elastic element to determine the deformation and transmit to the movable arm the closing force. The mechanism includes two cylindrical cam operating units housed inside the sleeve, having first and second cylindrical cams operatively facing one another such that rotation of one about the axis determines translation of the other along the same axis and vice versa,
