摘要:
A damper unit which brakes the speed of movement of a moving body by using a piston damper provided with a cylinder and a piston rod which is connected to a piston inside the cylinder, is provided. The damper unit includes a case wherein the above-mentioned piston damper is disposed; a transmitting member slidably provided inside the case and transmitting an external force accompanied by the movement of the above-mentioned moving body; a link member whose one end side is attached to the above-mentioned case so as to become the rotational center, and also whose the other end side is pivotally supported by the above-mentioned transmitting member; and a connecting member connected between both ends of the link member and being in contact with or connected to either the piston rod or the cylinder.

A controlled closure system for a sliding element of a piece of furniture, comprises an elongated body (15) provided in which is a rectilinear groove (20) passing through the body and extended axially in the closure direction. An engagement element (16) slides along the groove (20) to move from a first idle position to a second closure position through the action of a spring (29). The engagement element (16) comprises abutment surfaces to delimit, between them, a seat (44) intended to accommodate a drawing projection (17) integral with the sliding element. Suitable sliding surfaces between the engagement element (16) and the groove cause the rotation of the engagement element (16) when it is in the idle position in such a manner to lower the front abutment surface (48) towards a groove and allow the passage of the drawing projection (17) towards the closure until it pushes against the rear abutment surface and rotate the engagement element to raise the front abutment surface and draw the projection (17) towards the closed position of the sliding element of a piece of furniture.

A catcher 2 includes a catcher stopper 21, a holder 22 for a striker 1, and a biasing member 23 for the catcher stopper and the holder. When the catcher stopper 21 is projected by the biasing member 23, the holder 22 is set in a forward position and in a non-holding state, and when the holder 22 is set in a backward position and in a holding state, the catcher stopper 21 is withdrawn. The recess Mb has an engageable hole 402 formed therein for engagement with the catcher stopper 21, and a force is stored in the biasing member 3 when the catcher 2 is set in a reference position where the catcher stopper 21 is brought into engagement with the engageable hole 402. The sticker 1 enters the holder 22 of the catcher 2 when the catcher is set in the reference position since the movable member M is moved forward to a self-propelled movement start position.

Provided is a liquid damper device by which the operation of a movable body can be silently completed due to damping, the durability of a valve body can be improved, and the characteristics in the relationship between a moving speed and a drag of a piston can be adjusted in a wider range. A liquid damper device (1) is provided with a cylinder (3) in which a silicone oil is enclosed, a piston (5) which divides the inside of the cylinder (3) into a pressure chamber (11) side and a contra pressure chamber (13) side and which is provided with a piston rod (15) which protrudes outwardly from the cylinder (3), flow passages (41) provided in the piston (5) to cause the pressure to be adjusted, and a flexible valve body (42) for the flow passages (41). The surface (37) of the piston (5) which is located on the pressure chamber (11) side and into which the flow passages open is provided with convex surface portions (43) which locally support the outer peripheral edge of the valve body (42) at two points opposite to each other in the diametral direction of the piston (5) and a concave surface portion (45) which is formed between the convex surface surface portions (43). The flow passages (41) open at a bottom (45a) of the concave surface surface portion (45).

The invention relates to a furniture hinge (10) with a hinge arm (20) and a fastening portion (30), wherein the hinge arm (20) and the fastening portion (30) are pivotably connected to one another via a multi-axis articulated connection (40), and wherein a damping element (60), which damps in a deflection direction, for damping the movement of the hinge arm (20) and a spring (76) for adjusting the hinge arm (20) with respect to the fastening portion (30) are provided. It is provided here that the damping element (60) is mounted in such a way that, during a folding movement of the hinge arm (20) from a first end position into a second end position, a maximum or a minimum deflection of the damping element (60) is carried out within an adjusting movement of the damping element (60) caused by said folding movement. As a result, a furniture hinge which can be produced cost-effectively and which allows damped opening and closing of the hinge arm is provided.
