Definitions

  • This invention relates to a hinge with a damper which can be suitably used to be attached between a case such as a box etc., for example and a door thereof to moderately open or close the door.
  • hinges with the built-in damper is disclosed in patent document 1 and the hinge is formed by inserting damper parts into a pivotal portion of two hinge members from both sides.
  • This hinge comprises a piston type bellows damper attached between a free end of a lever pivotally supported in a hinge arm and the hinge arm.
  • the damper Since the hinge with the built-in damper of such a construction has the piston type damper provided between the hinge arm and the lever, the direction in which the hinge moves and the direction in which the damper moves are different from each other and therefore, the damper has the movement disordered out of a linear movement whereby the assembling of the hinge gets troublesome and therefore similarly it can be disadvantageously inapplicable to various forms of hinge.
  • the hinge with the damper is formed by the absolutely independent hinge and damper as shown in patent document 3, they have to be separately attached between the case and the door.
  • the attachment operation of them requires much labor and if they are attached to incorrect positions, the movement of the hinge and the movement of the damper interfere with each other so that they cannot interlock with each other. This makes the setting of the attachment position troublesome and the attachment operation cannot be effectively made.
  • An object of the invention is to provide a hinge with a damper adapted to be applicable to various forms of hinge without making troublesome the assembling of the hinge.
  • Another object of the invention is to provide a hinge with a damper adapted to easily assemble the damper.
  • a hinge with a damper provided with a hinge comprising first and second hinge members pivotally connected with each other and a damper for controlling the opening and closing of the first and second hinge members, characterized in that the damper comprises a first arm having one end pivotally supported on the first hinge member; a second arm having one end pivotally supported on the second hinge member; and damper force generation means provided between the other ends of the first and second arms and that the damper force generation means is adapted to generate a damper force by relative rotary movement of the first and second arms.
  • the damper force means may comprise a damper body to generate the damper force between stationery and movable sections, the movable section of the damper body may be in the form of a rotary shaft, the other end of the first arm may be secured to the stationery section of the damper body and the other end of the second arm may be in the form of being secured to the rotary shaft.
  • the second arm may comprise a pair of arm portions connected to each other at their connection and the damper body may be attached through a spacer between the pair of arm portions.
  • the rotary shaft may have a portion slightly protruding from one side of the damper body and the spacer may have a thickness almost corresponding to the length of the protrusion portion of the rotary shaft.
  • the rotary shaft and one arm portion of the second arm may be securely connected at their fitting portion and especially the fitting portion may be preferably angular fitting portion.
  • the other arm portion of the second arm may be rotatably disposed through a spacer between a fixed cap secured to the stationery section and the spacer.
  • the arm portion of the first arm on the side of the stationery section may have a fixed cap secured through the spacer to the stationery section of the damper body.
  • the first and second hinge members may be pivotally connected through a linkage arm to each other and the damper may be disposed between the first and second hinge members over the linkage arm.
  • the damper may be formed by disposing the movable section within a cylindrical case, which is the stationery section and the movable section may include the rotary shaft to be connected to the second arm.
  • the second arm may include the arm portions disposed on both sides of the cylindrical cases.
  • One end of the rotary shaft may have a head extending through these arm portions to engage with a part of the movable section and the other end of the rotary shaft may have a caulked portion to be forcibly tightened against an escape stopper plate engaging with the arm portion.
  • the damper comprises the first arm having one end pivotally supported on the first hinge member, the second arm having one end pivotally supported on the second hinge member, and the damper force generation means provided between the other ends of these first and second arms, the damper can be attached to the hinge members in the state of completion, but not contained in the hinge members and therefore the hinge with the damper can be easily assembled.
  • the damper since the damper is attached to the hinge, it may be easily attached to the opening and closing member such as a door or a cover. Since the damper is attached through the two arms to the hinge members, the movement of the hinge members can be converted into the relative rotation of the two arms and since the rotation of the arms induces the buffer function of the damper body, the motion of the hinge and the motion of the damper never interfere with each other and therefore the hinge can smoothly move.
  • the damper body can be easily attached to the second arm.
  • the damper body and the second arm can be assembled by inserting the damper body including the protrusion portion of the rotary shaft between the pair of arm portions of the second arm, thereafter fitting the protrusion portion of the rotary shaft into the one arm portion of the pair of arm portions and disposing the spacer between the other arm portion and the damper body and therefore the assembling of the damper with the arm can be effectively made.
  • the second arm has two arm portions engaging with the cylindrical case which is the stationery section into which predetermined parts are inserted and through which passes the rotary shaft, which is a part of the movable section and is caulked thereto to thereby effectively assemble the damper with the arm, similarly.
  • the hinge with the damper can be applied to various forms of hinge and therefore, its usage for general purposes can increase.

  • the viscous fluid 43F of the damper 30 is filled between the cylindrical case 42C and the intermediate annular member 44M of the switching mechanism 44 (see Figs. 15 through 18).
  • the damper action is generated by resistance of the viscous fluid 43F, but even though there is the relative rotation of the first and second arms 21 and 22, no damper action is generated unless there occurs the relative movement of the cylindrical case 42C and the intermediate annular member 44M.
  • the damper built-in hinge 10 is assembled as follows; Into the cylindrical case 42C of the damper 30 are inserted the middle cylindrical portion 42CM, the inner cylindrical portion 42BM and the intermediate annular member 44M having the key members 44K, which are the component parts for the switching mechanism 44.
  • the cylindrical case 42C having various parts contained therein in this manner is disposed between the pair of arm portions 34A and 34A' of the second arm 34 and then the removal stop plate 43W and the resistance body 43R are engaged from the outside of the pair of arm portions 34A and 34A'.
  • the resistance body 43R and the intermediate annular member 44M are bonded by the key members 44K, when the hinge 10 is moved from the position of Fig. 15 to the position of Fig. 16, the resistance body 43R and the intermediate annular member 44M rotate in a counterclockwise direction along the inner face of the cylindrical case 42C of the stationery section 42 in accordance with the rotation of the second arm 34 while they are subject to resistance by the viscous fluid 43F and the key members 44K of the switching mechanism 44 get faced to the arc-like cam recess face 42CC of the cylindrical case 42C of the stationery section 42.
  • the angle from the door complete closing position of Fig. 15 to the door half-opening position of Fig. 16 where the damper action works can be set at 30 degree, for instance. In this manner, the door is subject to some resistance when the door starts to be opened, but when the door should be closed, the door starts to be closed without any resistance and just before the door is completely closed, the damper action works.
  • the opening and closing operation of the door can be preferably performed in a smooth manner.
  • the damper built-in hinge 10 according to the form of embodiment of Fig. 13 and the succeeding figures can have less degree of reduction of the occupancy volume in the same manner as the damper built-in hinge 10 according to the form of embodiment of Figs. 1 through 12 and since the damper 30 is assembled to the hinge 20 in the state of completion, the damper built-in hinge 10 can be easily assembled.
  • the damper built-in hinge 10 of this form of embodiment has the damper 30 attached through the two arms 32 and 34 to the hinge members 21 and 22 in the same manner, the movement of the hinge members 21 and 22 is converted into the relative rotation of the two arms 32 and 34 of the damper 30 and this rotation induces the shock absorbing action of the damper body 41.
  • the movement of the hinge 20 never interferes with the movement of the damper 30 and the hinge 23 can move smoothly.
  • the damper 30 having the arms attached thereto can be effectively and assembled by inserting the rotary shaft 435, the intermediate annular member 44M including the key members 44K of the switching mechanism 44 etc., , which are the component parts of the movable section into the cylindrical case 42C which is the stationery section 42, then inserting the rotary shaft 43S and caulking the rotary shaft.
  • the hinge 20 has the linkage arm 23 provided between the first and second hinge members 21 and 22, the invention can be applied to the form in which the first and second hinge members 21 and 22 are pivotally supported on each other in a direct manner
  • the damper built-in hinge of the invention since the damper in the completed form is attached to the hinge members and is never contained within the hinge members, the damper built-in hinge can be easily assembled. Especially, the operation of attaching the arms to the damper can be effectively performed and the damper built-in hinge can be inexpensively provided with the result that the possibility of utilization in industries can be improved.
