Abstract:
A catch for two objects moveable in relation to one another, in particular a door catch, includes a cylinder, which is operatively connected to a first object, a friction surface carrier, which is operatively connected to a second object, a friction element for creating a frictional grip between the cylinder and the friction surface carrier through an energy input. The friction element being connected to an electrical voltage supply device, wherein a change in the volume of the friction element, which constitutes an actuating movement of the friction element in relation to the friction surface, occurs as a function of the voltage applied to the friction element.
Abstract:
A detented and dampened hinge mechanism with push-pull and pull-push operation is disclosed. The present invention relates generally to a hinge mechanism that includes a first arm and a second arm that are pivotally connected to one another such that the arms can be moved relative to one another between a closed position and an open position. A damper is fitted into a cutout of the second arm such that the damper can engage with a length of teeth of the first arm when the hinge mechanism moves between the open and closed positions. Biasing means is fitted between hooks or bosses of the arms, and biases the first and second arms toward the open position.
Abstract:
A sliding resistance member (3) is interposed between a glove box (B) and a rod type air damper (21). It is assumed that when a glove box lid (L) corresponding to a open-close member starts opening, the rod type air damper (21) rotates while running idle in conjunction therewith, in a relation in which the rotary type oil damper (3) is positively interposed between the glove box (B) corresponding to the mounting shaft and the rod type air damper (21). However, since a braking force of the sliding resistance member (3) is applied to the side of the open-close member in a rotating section of the rod type air damper (21), an sufficient damper effect can be obtained even when the open-close member starts opening.
Abstract:
The invention is directed to a simply designed and easy-to-operate brake retardation apparatus in which a push rod is moveable in guides of a housing and possesses a section formed as a gear rack which meshes with a pinion of a shock absorber also retained in the housing.
Abstract:
A pair of door mounting assemblies mount an oven door assembly to an oven such that the oven door assembly may move between a closed baking position, a broiling position, and an open position. Each of the door mounting assemblies includes a mounting member that is pivotally connected to the door assembly. Each door mounting assembly includes a spring biased mechanism to enable the oven door assembly to be biased by the weight thereof when in a first range of movement, to be biased toward and into the broiling position when in a second range of movement, and to be biased toward and into the baking position when in a third range of movement. A damper assembly provides resistance to the movement of the oven door assembly within the second and third ranges to limit the rate of movement of the oven door assembly toward the broiling and baking positions.
Abstract:
A damping device for damping the relative rotation of a rotating member. The damping device includes a casing, a rotor disposed in an interior space of the casing, and a damping mechanism including a viscous liquid disposed in an annular chamber formed between the casing and the rotor. The viscous liquid exerts frictional forces to damp the relative rotation between the rotor and the casing in a first rotation direction but not in the opposite rotation direction, the damping force increasing when the rotor and the casing rotate relative to each other from a first relative angular position to a second relative angular position in the first rotation direction. The casing and the rotor are structure to provide a damping force by impeding the flow of the viscous liquid within the chamber, and to provide another damping force by the contacting of the rotor and the casing. A valve is further provided within the chamber to restrict the flow of the viscous liquid. A toilet seat and lid unit incorporating two identically shaped damping devices, as well as a toilet bowl incorporating the seat and lid unit are also provided.
Abstract:
There is provided a hinge rotatably connecting a first body to a sacond body, including (a) a main body to be fixed onto the first body, the main bodyr including a hollow cylindrical portion horizontally extending, (b) a rotation shaft fixed at one end to the second body and rotatably connected at the other end to the main body, (c) an outer collar connected to the hollow cylindrical portion of the main body in a direction in which the hollow cylindrical portion extended extends and (d) a frictional collar filling space therewith between the rotation shaft and both the outer collar and the hollow cylindrical portion. For instance, the first body may be a keyboard, and the second body may be a display screen in a note-type computer. The hinge ensures smooth rotation between the first and second bodies, and further ensures a greater upper limit in the rotation number than that of a conventional hinge used in a note-type computer.
Abstract:
A rotary damper uses a motor to selectively dynamically brake the rotational movement between a housing and a cover of a wireless communications device. A clutch that is moveable between an engaged position and a disengaged position connects the motor to the cover so that the relative rotational movement between the housing and the cover in at least one rotational direction is resisted by the motor when the clutch is in an engaged position. The clutch preferably includes a coupler axially moveable between a deployed position directly engaging the flip cover and a retracted position disengaged from the cover, and an actuator moveable between a first position and a second position so as to cause the coupler to assume the deployed position and the retracted position, respectively. The actuator preferably includes a spring to bias the coupler towards the deployed position. A shaft preferably extends through the motor and connects the actuator to the coupler. The coupler may rotate at a slower speed relative to the shaft or may rotate at the same speed. The rotary damper may also include an eccentric weight attached to the shaft so as to spin therewith. When the clutch is in the disengaged position, the motor may intermittently spin the shaft causing the eccentric weight to spin, thereby imparting a shaking motion to the overall phone.
Abstract:
Door hinge with a locking device based on a field force, including a cylinder divided by a piston into working spaces that are filled with an operating medium whose viscosity can be changed by means of a field force. The working spaces are connected to one another by at least one flow connection that is subject to the influence of a field force generating element. The door hinge is designed as a pivot bearing, wherein the cylinder takes the form of a bearing eye and the piston takes the form of a rotary piston with at least one blade.
Abstract:
An overhead door is provided with a pair of stays and respective stay holding tension springs arranged such that, when the door is closed, they are expanded only less than twice of their length they have when the door is opened so that they are not subjected to excessive loads and hence can have a prolong service life. Each of the stays is rotatably fitted to the inner surface of a corresponding lateral wall of a cabinet main body by way of a rotary shaft and have its front end pivotably secured to the door at a position close to the lower edge of the door. A pair of slide rail assemblies, each comprising an outer rail and an inner rail 9b, are arranged such that the outer rails are fitted longitudinally in parallel with each other on the inner surface of the door and the upper end of each of the inner rails is pivotably secured to the front edge of the roof board of the cabinet main body. Each of the stay holding tension springs are soarranged that each of them is hooked at an end to a position located upward and forward relative to the corresponding rotary shaft on the inner surface of the related lateral wall of the cabinet main body and at the opposite end to a middle point of the corresponding stay. Thus, the outer rails and the door are urged upward relative to the inner rails by the stay holding tension springs so that the door may be opened lightly and the torque applied to the door when the door is closed is alleviated by the stay holding tension springs.
