Abstract

The invention discloses a furniture hinge, which comprises a movable cup seat connected through an articulated jib. A torsional spring for at least generating opening/closing acting force on the movable cup seat is arranged in the hinge. The furniture hinge is characterized in that a buffer for buffering in a hinge closing process is arranged in the movable cup seat; the articulated jib is connected with the buffer at least when the hinge is closed; the articulated jib or/and the buffer is/are provided with hinge closing working surfaces; and each hinge closing working surface is at least provided with one section of curved surface. One end of the articulated buffer is provided with at least one section of curved surface which is at least in surface or linear contact with the articulated jib in an articulation closing process, the shape, curvature and the like of the curved surface are designed, and useful force component acting on the curved surface of the buffer when the hinge is closed is kept invariant, reduced gradually or increased gradually, so that uniform-speed, uniform-decreased-speed or uniform-increased-speed closing of a door body is realized, collision among furniture is reduced during uniform-speed, uniform-decreased-speed or uniform-increased-speed closing of the door body, and low noise and high practicability are achieved.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

The first embodiment

Referring to Fig. 1-Fig. 5, this furniture hinge comprises the flexible cup base 1 that connects by articulated jib 2 and regulates cover plate 6 that articulated jib 2 one ends are hinged by bearing pin and flexible cup base 1, and the other end is by eccentric nail and adjusting 6 adjustable connections of cover plate.

Be provided with in the hinge at least flexible cup base 1 is produced the torsion spring 4 that opens and closes active force, torsion spring 4 is arranged on the cup of flexible cup base 1, and comprises that the first feet 4.1 is connected with articulated jib 2, and the second feet 4.2 is connected with flexible cup base 1; Described articulated jib 2 corresponding the first feets 4.1 arrange at least one section cambered surface 2.2 and are connected, also be provided with working of plastics 5 on the first feet 4.1, working of plastics 5 is connected in the hinge opening-closing process with the cambered surface 2.2 of articulated jib 2, and described working of plastics 5 is the opening shell-like.

Also be provided with the Automatic-reset hydraulic damper 3 that plays cushioning effect in the hinge closing process in the flexible cup base 1, articulated jib 2 is connected when hinge is closed at least with Automatic-reset hydraulic damper 3; Described articulated jib 2 is closed work plane or/and be provided with hinge on the Automatic-reset hydraulic damper 3.

Above-mentioned Automatic-reset hydraulic damper 3 comprises cylinder body 3.1 and piston rod 3.2; Be provided with groove position 1.1 in the cup of flexible cup base 1, cylinder body 3.1 is arranged on the groove position 1.1 by damper cover 7; Be provided with damping element (failing among the figure to show) in the cylinder body 3.1, piston rod 3.2 1 ends connect damping element, and the other end stretches out cylinder body 3.1 and joins with flexible cup base 1 inwall; The other end of cylinder body 3.1 is provided with hinge and closes work plane A, and articulated jib 2 corresponding hinges are closed work plane A and are provided with contact site 2.1, and contact site 2.1 is closed work plane A with hinge and contacted when hinge is closed at least.

The hinge of cylinder body 3.1 is closed work plane A and is overlooked and be plane, and as shown in Figure 6, it is that face contacts when hinge is closed that contact site 2.1 is closed work plane A with hinge;

Perhaps, the hinge of cylinder body 3.1 is closed work plane A and is overlooked V-shapedly, and such as Fig. 7, shown in Figure 8, it is that line contacts when hinge is closed that contact site 2.1 is closed work plane A with hinge.

More than the stationarity of two kinds of hinges technical scheme of closing work plane A can both guarantee that hinge is closed the time.

Referring to Fig. 9-Figure 11, the stressing conditions of hinge of the present invention in closing process: when hinge was closed, the hinge of 2 pairs of cylinder bodies 3.1 of articulated jib was closed work plane A and is produced respectively the vertical and F level of F; Wherein F vertically becomes the frictional force of damper 3, the F level is touched damper 3 and is shunk, cause hinge to be closed, namely hinge is closed the component F level of work plane A and angle that hinge is closed work plane A consists of the horizontal cosX of formula F=F by acting on the power F that closes hinge.

Among the horizontal cosX of formula F=F, acting on hinge closes in the poor situation of power F of work plane A, as long as the X angle is constant, just can not change for the power F that closes hinge, hinge is closed and is reached at the uniform velocity, then as long as in the hinge closing process, change at any time the contact angle X that contact site 2.1 and hinge are closed work plane A, just can realize at the uniform velocity closing of a body.In like manner, as long as angle X slowly increases progressively or slowly reduces, the door body is thereupon even to accelerate to close or speed is slowed down and closed.

Referring to Figure 12, Figure 13, the Another Application of articulated jib, difference is that articulated jib 2 and adjusting cover plate 6 are formed in one.

Referring to Figure 14, hinge is closed work plane A and is made of a plane and one section spill cambered surface, when hinge is closed, contact site 2.1 and the hinge of articulated jib 2 closed work plane A and contacted, along with hinge is closed, contact site 2.1 act on hinge close work plane A useful component because hinge to close the curvature of work plane A different, cause be used to the active force of closing hinge substantially to remain unchanged, thereby realize at the uniform velocity closing of door body.

The second embodiment

Referring to Figure 15, this furniture hinge, the hinge of cylinder body 3.1 is closed work plane A and is connected and composed by a plurality of planes.

The 3rd embodiment

Referring to Figure 16, this furniture hinge, the hinge of cylinder body 3.1 are closed work plane A and are made of one section spill cambered surface.

The 4th embodiment

Referring to Figure 17, this furniture hinge, the hinge of cylinder body 3.1 are closed work plane A and are connected and composed by one section spill cambered surface and one section convex-shaped arc surface.

Above-mentioned is preferred version of the present invention, and those of ordinary skills all drop within protection scope of the present invention its simple modification or transformation.
