PANIC DEVICE WITH DOOR CLOSER
Disclosed is a panic bar with a door closer, the panic bar having a locking device installed at a front end of a case and a door closer provided at a rear end of the case. The locking device is released upon pushing of the push bar provided in the case. An air cylinder is installed inside the case. A guide member is installed in one side of the air cylinder and a cylinder sealing cap is installed in the other side of the air cylinder. One side of a piston rod having a piston for compressing and expanding air inside the air cylinder passes through the guide member. A spring disposed between the piston and the guide member is installed on the piston rod.
Door closers
A door closer, including: an anchor assembly, including: a frame mounting plate which is fixable relative to a door frame; and an adjustor plate; and an actuator assembly for mounting within the thickness of a door leaf to move the door leaf between open and closed configurations relative to the door frame, the actuator assembly including an operating member coupled by a link to the adjustor plate and mounted for a range of movements between a fully retracted position, in which the anchor assembly is held adjacent the actuator assembly when the door leaf is in the closed configuration, and an extended position, in which the anchor assembly is in spaced relation to the actuator assembly when the door leaf is in the open configuration, the link being configured to extend from the adjustor plate along a first axis, wherein the frame mounting plate is provided with one or more slot(s), the or each slot being elongated along a second axis, the second axis being generally orthogonal to the first axis.
FURNITURE DAMPER
A furniture damper includes a damper housing, a fluid chamber therein, a damping fluid therein, and a piston displaceably supported within the fluid chamber. A switch element can be moved, when a damping stroke is below a predetermined pressure threshold value, into a first position in which the channel of the piston is at least partially covered by the switch element and a first flow rate of the damping fluid streams through a channel of the piston. The switch element is also configured to be moved, when the damping stroke is above the predetermined pressure threshold value, from the first position into a second position in which the channel of the piston is at least partially unblocked by the switch element and a second flow rate of the damping fluid streams through the channel of the piston, with the second fluid rate being larger than the first fluid rate.
Lift assist and damper arrangement
A lockable lift assist assembly includes a piston assembly moveable between an extended position and a retracted position. A valve assembly is coupled in movement together with the piston assembly. The valve assembly is configured to selectively alter a flow of a hydraulic fluid through a fluid communication path established within the valve assembly to control movement of the piston assembly.
Movement Control Device
A movement control device comprising a housing with an elongate push rod mounted therein for reciprocal movement along a longitudinal axis between first and second positions, wherein the push rod extends out of said housing in both the first and second positions. A spring comprising a primary axis operable to provide a biasing force on the push rod is further provided in the housing. A damping device comprising a primary axis is located in the housing, wherein the damping device is in continuous engagement with the push rod through its reciprocating movement. The primary axis of the spring and the primary axis of the damping device are not coaxial.
ACTUATOR RATE CONTROL WITH ENERGY ABSORBING PRESSURE RELIEF SYSTEM
An actuator includes a piston assembly movably disposed within an assembly housing having a fixedly supported end and an opposing end that receives a movable piston assembly. The piston assembly includes a piston rod and an attached piston head having a fixed orifice as well as an orifice with a check valve to create rate control of the assembly. Hydraulic fluid is caused to move through the axially movable piston head based on compressive and tensile loads imparted to the assembly. A plurality of pre-loaded springs are configured to selectively provide pressure relief in the event the orifices of the piston become clogged, wherein the plurality of pre-loaded springs, such as disc springs, further provide an energy absorbing function of the assembly based on loading conditions.
Device for closing a hinged member
A closing device includes an actuator mechanism and a hydraulic damper mechanism. The actuator mechanism includes a pushrod urged by a resilient member towards its extended position. The hydraulic damper mechanism includes a piston, a first rack and pinion gearing for converting the translational motion of the pushrod into a rotational motion of a first pinion, a transmission, which includes a second rack and pinion gearing, between the first pinion and the piston for transmitting and converting the rotational motion of the first pinion into a translational motion of the piston, a one-way valve allowing fluid flow from a first side to a second side of the cylinder cavity when opening the hinged member, and a restricted fluid passage between the first and second sides of the cylinder cavity. The transmission provides together with the pinions of the first and second rack and pinion gearings a reduction gearing between the pushrod and the piston so that the piston reciprocates over a smaller distance than the pushrod.
DAMPING DEVICE AND FURNITURE HINGE COMPRISING THE SAME
A damping device includes a housing, a cover assembly, a piston rod, a piston and an elastic member. The housing has an inner wall defining a chamber, and an opening communicated with the chamber. The chamber is filled with a damping medium. The cover assembly is arranged adjacent to the opening of the housing. The piston rod penetrates through the cover assembly. The piston is connected to the piston rod and movable relative to the housing. The piston includes an extension part and an expansion part located between the piston rod and the extension part. A width of the expansion part is greater than a width of the piston rod. The elastic member is arranged in the chamber of the housing, and configured to provide an elastic force to the piston.
Device for a system for opening / closing a door or sliding shutter
A device for a system for opening/closing a door or a sliding shutter includes a jacket defining a longitudinal axis and a rod, having a cylinder at one end inserted into the jacket and an opposite end external thereto, which reciprocally slides along the longitudinal axis or along an axis parallel thereto in relation to the jacket between a position proximal to the jacket and a position distal therefrom.
DECELERATED HINGE FOR FURNITURE AND METHOD FOR ASSEMBLING A DECELERATING DEVICE IN A FURNITURE HINGE
A decelerated hinge for furniture, which comprises a hinge arm, a hinge box fixable to a door and swingably connected to the hinge arm by an articulation axis at a rear wall of the hinge box, elastic closing means for closing the hinge and a linear-type decelerating device comprising a housing body, a slider, a fluid damper and elastic return means, wherein the hinge box has at least one opening in at least one of a front and/or side walls, and wherein the housing body has at least a retaining protrusion conformed and arranged to be inserted in the at least one opening in such a way to be protruding outside the hinge box, wherein the retaining protrusion inserted in the opening cooperates with fixing means by which the housing body is fixed in the hinge box.
