Description

  The present invention is provided with a damper used to close and move a movable object such as a door in front of a fixed object such as a case or move along a side wall of the fixed object to open and position on a side surface of the fixed object. This relates to the improvement of the hinge.

  It is required in various fields that a movable object such as a door is positioned in front of a fixed object such as a case and closed, or moved along a side wall of the fixed object and opened on a side surface of the fixed object. . For example, when the interface part of the computer main body is arranged on the front side of the computer main body, the front face looks bad, and foreign objects such as dust can easily enter the insertion hole of the interface part, and there is a door that opens and closes the interface part. (For example, refer to Patent Document 1).

    However, the door disclosed in Patent Document 1 has a pinion rack means for horizontally moving the door laterally with respect to the front of the case, and pivoting the door along the side wall of the case at the door open position. In addition to having a complicated structure, the operation for horizontally moving the door and the operation for pivoting the door are required, and the operation for opening and closing the door is complicated. .

  Therefore, it is desirable to use a hinge that can be rotated so that a movable object such as a door is continuously displaced from the front side to the side surface of a fixed object such as a case.

  However, since a simple hinge simply opens and closes a movable object with respect to a fixed object, the opening and closing operation of the movable object is performed rapidly, and the movable object is moved to the fixed object in a shocking manner or in the closed or open position. Since the movable object becomes unstable, a damper is incorporated in the hinge so that the movable object is opened and closed with resistance, and the movable object is kept in a stable state at the closed position or the open position of the movable object. It is preferred that it be possible.

  Conventionally, hinges with dampers have been used in various fields. However, if the dampers are arranged away from the pivot part of the movable member of the hinges, a separate space in which the dampers are to be placed is required or the dampers and hinges are arranged. This requires a mechanism for connecting the pivot part to the device, and the device using the damper-equipped hinge is undesirably large (see, for example, Patent Documents 2 and 3).

  When the damper is built in the pivot part of the movable member of the hinge, a separate space in which the damper is to be arranged is not required, and thus the apparatus can be reduced in size as a whole (for example, Patent Document 4). reference).

  However, this type of hinge with a damper of the prior art incorporates the completed damper in the case of the hinge pivot part, so that the damper is incorporated into the hinge pivot part and the pivot part and the hinge. There is a drawback that the assembly with the members needs to be performed separately, and the assembly is troublesome. In addition, the pivot portion for accommodating the damper becomes large, and the hinge cannot be miniaturized.

  One problem to be solved by the present invention is to provide a damper-equipped hinge that can be assembled easily by simultaneously incorporating the damper and assembling the hinge.

  Another problem to be solved by the present invention is to provide a damper-equipped hinge that can be miniaturized as a whole without increasing the size of the pivot portion into which the damper is incorporated.

  The present invention relates to a hinge with a damper to be provided between a fixed object and a movable object attached to the fixed object so as to be openable and closable, and a mounting bracket to be attached to the fixed object and a movable object to be held However, the present invention is directed to a damper-equipped hinge including an arm member pivotally attached to a mounting bracket and a damper provided at a pivot portion of the arm member.

Basic problem-solving means of the present invention, which is provided between the movable object mounted openably to the fixed body and the fixed body, a mounting bracket for fixing the object mounting, said as a movable object retaining an arm member mounted pivotally to the mounting bracket, the damper hinged consisting of a damper provided in the pivot of the arm member, has the form of a substantially U-shaped mounting bracket is made from a resilient material The upper and lower plate pieces of the mounting bracket each have a shaft hole, and the damper is composed of a circular recess formed in the pivot part of the arm member and a damper disk housed in the circular recess, And the axis of the pivot part of the arm member is composed of a shaft part extending from the upper surface of the damper disk and a shaft part extending from the bottom part of the circular recess, and One of the shaft portions of the lower plate piece corresponds to the shaft hole of the lower plate piece, and the other shaft portion corresponds to the shaft hole of the upper plate piece, and In the relative relationship between the mounting bracket, the arm member, and the damper, the pivot portion of the arm member is inserted between the upper and lower plate pieces of the mounting bracket by expanding the pivot portion of the arm plate while expanding the openings of the two plate pieces. The shaft portion of the damper disk is fitted and fixed in the shaft hole of the upper plate piece and the shaft portion of the circular recess is fixed to the shaft of the lower plate piece by the intervention of the pivot portion between the two plate pieces. The two plate pieces are expanded by being fitted in the hole and rotatably supported , and the shaft portions are fitted in the two shaft holes .

  In the basic problem-solving means of the present invention, the first member that suppresses the arm member from moving in the closing direction with respect to the mounting bracket beyond the inner stop position slightly beyond the position where the movable object closes. And second stopper means for restraining the arm member from moving in the opening direction with respect to the mounting bracket beyond the outer stop position slightly beyond the position where the movable object is completely opened. It is preferable.

    In this case, the first stopper means is formed on a connecting plate piece that connects the end surface opposite to the free end of the arm member and the upper and lower plate pieces of the mounting bracket, and the notch end surface with which the end surface of the arm member engages. It can consist of

    Further, the second stopper means may be composed of a protruding portion provided on the arm member and a stopper surface which is formed on the side end surface of the mounting bracket and engages with the protruding portion.

  In particular, the damper includes a circular recess formed in the pivot portion of the arm member, a damper disk housed in the circular recess, and a damper cap that closes the circular recess so as to close the damper disk. The shaft preferably comprises a shaft portion extending from the damper disk and a shaft portion extending from the bottom of the circular recess.

    The damper also includes a damper cap that closes the circular recess to close the damper disk, and a damper liquid that is stored in a damper space surrounded by the circular recess and the damper cap, and the shaft portion extending from the damper disk has a damper cap. It is preferable to pass through.

  According to the present invention, the shaft of the pivot part of the arm member and the damper are accommodated while the openings of the upper and lower plate pieces of the substantially U-shaped mounting bracket are expanded, and the arm member and the damper can be rotated to the mounting bracket. Since it can support, an arm member and a damper can be attached to a mounting bracket by one touch, an assembly is easy and a hinge with a damper can be provided at low cost.

  The arm member has a first stopper means for restraining the movable object from moving further in the closing direction at the inner stop position slightly beyond the closed position, and slightly exceeds the position where the movable object is fully opened. The second stopper means for preventing the arm member from being moved further in the opening direction at the outer stop position allows the arm member to be stored and transported without excessively closing and opening the arm member. It can be prevented from being damaged in some cases.

  In this case, the first and second stopper means respectively stop the arm member at an inner stop position slightly exceeding the position where the movable object closes and an outer stop position slightly exceeding the position where the movable object is completely opened. Therefore, when the mounting bracket is attached to the fixed object and the arm member is attached to the movable object, the opening and closing of the movable object is not interfered by this stopper means, and therefore the movable object is completely opened or completely closed. It is not hindered to do.

    In particular, when the damper is composed of a damper disk housed in a circular recess formed in the pivoting portion of the arm member, the arm member also serves as a damper casing, and the damper is integrally incorporated. By reducing the diameter of the moving part, the hinge with the damper can be downsized as a whole.

    In this case, since the shaft portion extending from the damper disk and the shaft portion extending from the bottom of the circular recess can be used as the shaft portion of the pivot portion of the arm member, the length in the axial direction is shortened and the hinge with the damper is reduced in size. Can be

    In addition, a liquid type damper having a damper cap that closes a circular recess so that the damper closes the damper disk, and a damper liquid housed in a damper space surrounded by the circular recess and the damper cap can be easily configured. In this case, the shaft portion extending from the damper disk can be supported by the mounting bracket by penetrating the damper cap.

  An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows one use example of a hinge 10 with a damper according to the present invention.

Finally, it is positioned so as to be substantially parallel to the side wall (side surface) of the computer main body 1.

    Of course, the damper-equipped hinge 10 of the present invention can be used to attach a movable object to any fixed object other than the computer main body so as to be freely opened and closed.

The damper- equipped hinge 10 of the present invention, as shown in FIGS. 5 to 7, should hold a mounting bracket 20 to be attached to a computer main body (fixed object) 1 and a door (movable object) 2 and is to be attached to the mounting bracket. The arm member 40 is pivotally attached to the arm 20 and the damper 60 is provided on the pivot portion 50 of the arm member 40. The mounting bracket 20 and the arm member 40 can be made of any material, but are preferably made of plastic.

  The mounting bracket 20 is made of an elastic plastic material. As shown in FIGS. 5 and 7, the upper and lower plate pieces 22U and 22L and the upper and lower plate pieces 22U and 22L are connected at one end thereof. 22C has a substantially U-shaped form integrally formed.

  Further, the mounting bracket 20 integrally has upper and lower mounting flanges 24UF and 24LF extending in opposite directions at the ends of the upper and lower plate pieces 22U and 22L on the opposite side to the connecting plate piece 22C. As shown in FIGS. 2 to 4, the flanges 24 </ b> UF and 24 </ b> LF are used to screw onto the inner surface of the end wall 1 </ b> W of the computer main body 1 that is a fixed object.

  The mounting bracket 20 has shaft holes 26UH and 26LH in which the shaft of the pivot portion of the arm member described later is engaged and supported at a portion of the upper and lower plate pieces 22U and 22L close to the connecting plate piece 22C. Shaft guide grooves 28UG and 28LG extending from end portions on the side having flanges 24UF and 24LF to shaft holes 26UH and 26LH are provided on the inner surfaces of the upper and lower plate pieces 22U and 22L.

  As shown in FIGS. 9 to 12, the mounting bracket 20 has a protruding plate portion 30 </ b> L that protrudes laterally from the upper plate piece 22 </ b> U on the lower plate piece 22 </ b> L, and the protruding plate portion 30 </ b> L has an inner surface. In addition, a spring retaining pin 32 is provided integrally with which one end of a winding spring of an elastic means described later is latched.

  As shown in FIGS. 5 to 7, the arm member 40 includes a substantially trapezoidal base portion 42 and an elongated arm 44 extending in a lateral direction from one side of the base portion 42, and has a substantially L-shaped form as a whole. Have As shown in FIG. 9, the base portion 42 and the arm 44 have horizontal wall portions 42HW and 44HW and vertical wall portions 42VW and 44VW that integrally extend downward from the outer side edges, respectively. The vertical wall portion 42VW of the base portion 42 extends to a part of an edge that is continuous with the outer side edge of the base portion 42, and this extended portion is indicated by reference numeral 42VWE. Similarly, the vertical wall portion 44VW of the arm 44 extends in an approximately L shape to an end edge continuous to the outer side edge of the arm 44 and a part of the inner side edge, and this L-shaped extension. The part is indicated by reference numeral 44VWE.

  The arm 44 has a notch hole 46H into which the positioning pin 2P of the door (movable object) 2 to be attached to the arm member 40 is to be engaged, and the notch hole 46H is connected to the horizontal wall 44HW of the arm 44. Since it is formed so as to straddle the vertical wall portion 44VWE, the cutout hole 46H has a substantially inverted L shape.

  Further, the arm 44 has a thin movable object mounting wall 44E integrally extending at right angles from the vertical wall extension portion 44VWE on the inner side edge thereof, and this movable object mounting wall 44E has a vertical wall extension due to its small thickness. Recessed stepwise with respect to the portion 44VWE. Further, a metal screw cylinder 48 is integrally embedded in the movable object mounting wall 44E. The screw cylinder 48 is formed by overlapping the protrusion 2S of the door (movable object) 2 so that the protrusion of the door 2 protrudes. The set screw 100 is screwed over the portion 2S and the screw cylinder 48.

    Accordingly, the door (movable object) 2 is fixedly attached to the arm member 40 by engaging the positioning pin 2P into the cutout hole 46H of the arm 44 and screwing the projection 2S (not shown) and the screw cylinder 48. .

  As shown in FIGS. 9 to 12, the arm member 40 is integrally provided with a spring retaining pin 49 on the lower surface of the horizontal plate wall 42 </ b> HW of the base portion 42 so that the other end of the spring of the resilient means described later is latched. .

  The pivot portion 50 of the arm member 40 includes a shaft 50X that is rotatably supported between the upper and lower plate pieces 22U and 22L of the mounting bracket 20 together with the damper 60. The pivot portion 50 is illustrated in FIG. This will be described in detail later with reference to FIG.

  In the hinge 10 with a damper according to the present invention, the arm member 40 does not further move in the closing direction beyond the inner stop position where the door (movable object) 2 slightly exceeds the position where the computer main body (fixed object) 1 is closed. The arm member 40 is not further moved in the opening direction beyond the outer stop position slightly beyond the position where the first stopper means 70 and the door (movable object) 2 are completely opened. And second stopper means 80 to be suppressed.

    The first stopper means 70 includes an inner end surface 72 (see FIGS. 7 and 9 to 12) of the end wall of the base 42 opposite to the free end of the arm member 40 (the tip of the arm 44) and the mounting bracket 12. It consists of a notch end surface 74 (see FIGS. 9 to 12) formed on the connecting plate piece 22C and with which the end surface 72 of the arm member 40 engages.

    Further, as shown in FIGS. 9 to 12, particularly FIG. 12, the second stopper means 80 includes a protruding portion 82 provided on the base portion 42 of the arm member 40 and the side of the plate piece 22 </ b> U above the mounting bracket 20. It comprises an end face and a stopper face 84 with which the protrusion 82 is engaged.

  FIG. 9 shows a state where the first stopper means 70 is working, and FIG. 12 shows a state immediately before the second stopper means 80 works (a state where the door is completely opened). In the state of FIG. 9, the arm member 40 is displaced in the door closing direction from the position of FIG. 2 where the door (movable object) 2 is completely closed. In the state shown in FIG. 12, the arm member 40 is in a position corresponding to the position where the door (movable object) 2 is fully opened. The stopper means 80 of 2 acts to displace the arm member 40 slightly in the opening direction of the door. This is because the door (movable object) 2 completely opened the computer main body ('fixed object) 1. The outer stop position is slightly beyond the position.

    In this way, the arm member 40 can be moved further by the first and second stopper means 70, 80 at the fully closed position of the door (movable object) 2 and the stop position inside and outside slightly beyond the fully opened position. Otherwise, even if the arm member 40 is urged in the closing direction and the opening direction by the elastic means described later, the hinge 10 with the damper is not displaced in the closing direction and the opening direction. Can be maintained.

  Further, in this way, the first and second stopper means 70, 80 have an inner stop position where the door (movable object) 2 slightly exceeds the fully closed position, and the door (movable object) 2 slightly moves to the fully open position. When the arm member 40 is stopped at the outer stop position exceeding the position (1), when the mounting bracket 20 is attached to the computer main body (fixed object) 1 and the arm member 40 is attached to the door (movable object) 2, the door ( The opening and closing of the movable object 2 is not incomplete by these stopper means 70, 80, and therefore the door (movable object) 2 is not prevented from being fully opened or completely closed. It is advantageous.

  The damper 60 includes a circular recess 62 formed in the pivot portion 50 of the arm member 40, a damper disk 64 accommodated in the circular recess 62, and a damper cap 66 that closes the circular recess 62 so as to confine the damper disk 64. And a damper liquid (not shown) housed in a damper space surrounded by the circular recess 62 and the damper cap 66. As shown in FIGS. 8A and 8D, the damper disk 64 has a large number of liquid grooves 64G formed in the radial direction on the upper and lower surfaces thereof, and the damper liquid is composed of these liquid grooves 64G. It has a function to brake the damper disk 64 from entering and rotating.

    Therefore, it is understood that the damper 60 is formed with a part of the arm member 40 as a case, and the diameter of the pivot portion 50 can be reduced as compared with the case where the completed damper is incorporated.

    In this case, the shaft 50 </ b> X of the pivot portion 50 includes a shaft portion 64 </ b> A extending from the damper disk 64 through the disk cap 66 and a shaft portion 62 </ b> A extending from the bottom of the circular recess 62. In FIG. 6, reference numeral 68 denotes an O-ring fitted between the shaft portion 64 </ b> A of the damper disk 64 and the disk cap 66.

  As shown in FIG. 9, the elastic means 90 includes a winding spring 92, and one circular end 92 a of the winding spring 92 is hooked on the spring retaining pin 32 of the mounting bracket 12, and the other circular shape. The end 92 b is hooked on the spring stopper pin 49 of the arm member 40.

  Normally, the resilient means 90 urges the arm member 40 to the movable object closed position (see FIG. 10) or the movable object open position (see FIG. 12), and moves the arm member 40 from the closed position to the open position. Or, when moving from the open position to the closed position, both circular ends 92a and 92b are compressed so as to approach each other while being slightly opened from the neutral position (see FIG. 11) (counterclockwise in FIG. 11). ) Or the closing direction (clockwise in FIG. 11), the arm member 40 has a function of urging the arm member 40 to automatically move to the open position or the closed position.

  As described above, the first and second stopper means 70, 80 are configured so that the arm member 40 slightly exceeds the closed position (position shown in FIG. 10) or the open position (position shown in FIG. 12) by the elastic means 90. It has a function to prevent excessive displacement beyond the position (inner stop position or outer stop position).

As shown in FIGS. 6 and 7, the hinge 10 with a damper according to the present invention accommodates a damper disk 66 together with a damper liquid in a circular recess 62 of an arm member 40, and covers a damper cap 66 through an O-ring 68. The arm member 40 and the upper and lower plate pieces 22U of the mounting bracket 20 are fixed together with the damper 60 while the winding spring 92 of the elastic means 90 is spanned between the mounting bracket 20 and the spring retaining pins 32 and 49 of the arm member 40. 22L is expanded and inserted between these plate pieces 22U, 22L, and the shaft portions 64A, 62A of the damper 60 are engaged with the upper and lower shaft holes 26UH, 26LH of the mounting bracket 20 for assembly. In this assembly, the arm member 40 is inserted into the mounting bracket 20 while the shaft portions 64A and 62A are guided along the shaft guide grooves 28UG and 28LG of the mounting bracket 20. When the arm member 40 and the damper 60 reach a predetermined position of the mounting bracket 20, the upper and lower plate pieces 22U and 22L of the mounting bracket 20 automatically expand and the assembly is completed.

    With this assembly method, it can be seen that the operation of assembling the damper 60 into the arm member 40 and the operation of assembling the arm member 40 and the damper 60 to the mounting bracket 20 are performed simultaneously. Further, in this assembled state, the arm member 40 is not excessively closed or opened with respect to the mounting bracket 20 by the first and second stopper means 70, 80, and the combined state of both may be damaged. In addition, it is easy to store and manage the hinge 10 with the damper.

  As shown in FIGS. 2 to 4, the hinge 10 with a damper according to the present invention is fixed by screwing the mounting bracket 20 to the inside of the end wall 1W of the computer main body (fixed object) 1 with the mounting flanges 24UF and 24LF. The positioning pin 2P of the door (movable object) 2 is inserted into the notch hole 46H of the arm member 40, and the mounting protrusion 2S of the door 2 is superposed on the movable object mounting wall 44E of the arm member 40. The door (movable object) 2 can be attached to the computer main body (fixed object) 1 by being fixed to the movable object attachment wall 44E.

  The interface part of the computer main body 1 to which the door (movable object) 2 is attached in this way can be opened and closed by the door 2, and the door 2 is opened and closed by the winding spring 92 of the resilient means 90. However, when the neutral position (position in FIG. 11) is slightly exceeded, the door 2 is opened in the opening direction (counterclockwise in FIG. 11) or in the closing direction (by the counterclockwise direction in FIG. 11). It moves automatically in the clockwise direction in FIG. At this time, since the damper 60 suppresses the sudden movement of the door 2, the door 2 moves slowly so as to open and close the door 2, thereby reducing the impact when the door 2 is opened and closed.

  As already mentioned, the first and second stopper means 70, 80 are arranged in the fully closed position (position in FIG. 10) or fully open position (FIG. 12) before the hinge 10 with damper is attached. Since the arm member 40 is stopped at a position slightly exceeding (position) (position slightly displaced in the clockwise direction from the position in FIG. 9 and the position in FIG. 12), the door ( When the movable object 2 is attached to the computer main body (fixed object) 1, the first and second stopper means 70 and 80 do not work, and the door (movable object) 2 is completely attached to the computer main body (fixed object) 1. Can be opened and closed to a closed position or a fully open position.

  According to the present invention, the shaft and the damper of the pivoting portion of the arm member are accommodated in the mounting bracket, and the arm member and the damper can be attached to the mounting racket with one touch. To improve industrial usability.
