Description

  The present invention relates to a slide hinge with a damper provided with a damper device.

  Generally, a slide hinge used for furniture or the like is a housing-side mounting member that is attached to the inner surface of the housing of the furniture, and a horizontal direction between a closed position and an open position via a pair of links to the housing-side mounting member. A door-side mounting member that is pivotally connected and fixed to the back surface of the furniture door, and the door-side mounting member is positioned between a predetermined neutral position and a closed position between the closed position and the open position. And a rotation urging means for urging and urging the door side mounting member toward the closed position. In such a slide hinge, when the door is closed and rotated from the open position toward the closed position to the neutral position, the door is thereafter closed and rotated to the closed position by the rotation biasing means. The door is relatively fast when it reaches the closed position. When the door rotates to the closed position at a high speed, there is a problem that the furniture becomes less elegant. In addition, there is a problem in that a loud impact sound is generated due to the door colliding with the housing at high speed.

  Therefore, recently, a slide hinge with a damper provided with a damper device is frequently used. As described in Patent Document 1 below, the slide hinge with a damper is provided with a damper device on the door-side mounting member. The damper device has a movable member that can advance and retreat, and a damper mechanism that suppresses the retreating speed of the movable member to a low speed, and when the door reaches a predetermined contact position from the closed position to the neutral position, The movable member hits the tip of the housing side mounting member. Thereafter, the movable member slides on the housing side mounting member toward the rear end side with the rotation of the door toward the closed position, and is moved backward by the housing side mounting member. At this time, the backward movement of the movable member is suppressed to a low speed by the damper mechanism, and the closing rotation speed of the door is suppressed to a low speed. As a result, a high-class feeling as furniture can be obtained. Further, it is possible to prevent a large hitting sound from being generated when the door collides with the housing.

  By the way, as described in Patent Document 2 below, there is a slide hinge in which a protruding portion is provided at the front portion of the housing side mounting member. The protruding portion is protruded in a direction orthogonal to both directions of the rotation axis direction of the pair of links and the direction connecting the front end portion and the rear end portion of the housing-side mounting member. That is, it is made to protrude toward the other inner surface from one inner surface of the housing to which the housing side attachment member was attached. And a pair of link is provided in the protrusion part so that rotation is possible. Thus, when the door is rotated to the open position, the door is positioned as far forward as possible in the direction from the one inner surface to the other inner surface.

  It is demanded to attach a damper device also to a slide hinge having a protrusion. When the damper device is provided on such a slide hinge, the movable member hits the front end surface of the protruding portion, and slides on the front end surface of the protruding portion toward the rear end side as the door is closed. However, the movable member comes off the rear end side from the front end surface of the protruding portion before the door reaches the closed position. Therefore, after that, the damper effect cannot be obtained. In addition, depending on the slide hinge, it may not be possible to design the movable member to abut against the protruding portion. In any case, in the case of a slide hinge having a protrusion, the damper device cannot be attached so as to obtain a damper effect. For this reason, none of the conventional slide hinges having the protrusions are provided with a damper device.

In order to solve the above problems, the present invention is connected to the housing side mounting member and the front end portion of the housing side mounting member via a pair of links so as to be rotatable between a closed position and an open position. A door-side mounting member; and a rotation urging means for rotating the door-side mounting member from a predetermined neutral position between the closed position and the open position to the closed position, A protruding portion that protrudes in a direction orthogonal to both directions of the rotation axis direction of the pair of links and the direction connecting the front end portion and the rear end portion of the housing-side attachment member is formed at the front end portion, In the slide hinge in which the pair of links are rotatably attached to the projecting portion , a contact member is provided on the housing-side mounting member separately from the housing-side mounting member and the projecting portion. The contact member is provided with a contact surface facing the protruding direction of the protruding portion. This abutment surface is the skeleton side is disposed in front of the mounting member with respect to the rear end portion from the protruding portion in the projecting direction of the projecting portion, the above-mentioned door side attachment member, the movable member and movable A damper device having a damper mechanism that suppresses the moving speed of the movable member to a low speed is provided, and the door side mounting member is moved to the closed position when the door side mounting member is turned from the neutral position to the closed position. The movable member comes into contact with the contact surface of the contact member, and the door-side mounting member is turned from the contact position to the closed position. with it, the movable member is the slide towards the top the contact surface to the rear end side together, characterized in that it is moved by the abutment surface.
In this case, when the door-side mounting member reaches the front contact position in front of the contact position by a predetermined angle during the closing rotation of the door-side mounting member, the movable member is brought into contact with the front end surface of the protruding portion. The movable member slides toward the rear end side on the front end surface of the projecting portion as the door side mounting member rotates from the front contact position to the closed position side, and At least a tip portion of the contact surface that is moved by the tip surface and is adjacent to the protrusion is disposed on a rear extension of the tip surface of the protrusion, and the door-side mounting member is turned and closed. When the contact position is reached, it is desirable that the movable member moves from the tip end surface of the projecting portion onto the contact surface of the contact member and slides on the contact surface.

According to the present invention having the above-described characteristic configuration, when the door-side mounting member reaches a predetermined contact position when the door-side mounting member is turned, the movable member contacts the contact surface of the contact member. Thereafter, when the door-side mounting member rotates to be closed from the contact position to the closed position, the movable member slides on the contact surface and is moved by the contact surface. At this time, the moving speed of the movable member is suppressed to a low speed by the damper mechanism. Therefore, a damper device can be mounted even on a slide hinge in which a protrusion is provided on the housing-side mounting member, and the damper device can suppress the closing rotation speed of the door-side mounting member near the closed position to a low speed. it can.
In addition, when the movable member is brought into contact with the front end surface of the protruding portion, the angle at which the door is closed and rotated before the movable member moves from the front end surface of the protruding portion to the abutting surface of the abutting member. As a result, it is possible to widen the angle range in which the rotation speed of the door can be kept low. Furthermore, since the contact surface is located on the extension of the tip surface, the movable member can smoothly transfer from the tip surface of the protrusion to the contact surface of the contact member.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows furniture A in which a slide hinge 1 with a damper according to the present invention is used. The furniture A includes a rectangular parallelepiped box B having a front surface opened, and a plate-like door C that opens and closes the opening of the box B. One side of the door C (the left side in FIG. 1) has two damper hinges 1 and 1 on one side of the casing B (the damper device 3 described later is omitted for the lower slide hinge 1). And is supported so as to be rotatable in the horizontal direction. The door C is rotatable between a closed position where the opening of the housing B is closed and an open position shown in FIG. 1 which is approximately 90 ° away from the closed position. The slide hinge 1 can be applied to other than the furniture A.

  As shown in FIGS. 2 to 4, the damper-equipped slide hinge 1 includes a hinge portion 2, a damper device 3, and a contact member 4.

  The hinge part 2 has a base part 21. This base 21 is fixed to one side inner surface of the housing B (in FIG. 1, the left side inner surface. Hereinafter, the top, bottom, front, back, left, and right refer to the top, bottom, front, back, left, and right in FIG. 1). A first intermediate member 22 is provided on the base 21 so as to be adjustable in the vertical direction (in FIG. 3, the front and back direction in the drawing), and is fixed by a bolt B1. A second intermediate member 23 is detachably attached to the first intermediate member 22 by a known attachment structure. The second intermediate member 23 is provided with a housing-side mounting member 24 whose longitudinal direction is the front-rear direction (left-right direction in FIG. 3) so that the position can be adjusted in the front-rear direction, and is fixed by a bolt B2. An adjustment screw B <b> 3 is provided between the distal end portion of the second intermediate member 23 and the distal end portion of the housing-side mounting member 24. The position of the distal end portion of the housing side mounting member 24 is adjusted in the left-right direction (vertical direction in FIG. 3) by the adjusting screw B3. Therefore, the housing side attachment member 24 is detachable from the housing B. In addition, the position of at least the tip of the housing-side mounting member 24 can be adjusted in the vertical and front-back and left-right directions with respect to the housing B. The housing side mounting member 24 may be directly fixed to the housing B.

  A protruding portion 24 a is formed at the distal end portion (the end portion located on the front side of the housing B) of the housing-side mounting member 24. This protrusion 24a protrudes horizontally in the direction from one side of the housing B to the other side, that is, in the right direction. One end of a pair of links 25 and 26 is connected to the projecting portion 24a via a shaft S1 and S2 whose axis is directed in the vertical direction so as to be rotatable in the horizontal direction. Here, when the projecting direction of the projecting portion 24a is defined using the axial direction of the shafts S1 and S2 and the front-rear direction of the housing-side mounting member 24, the projecting portion 24a corresponds to the axial direction of the shafts S1 and S2 and the housing-side mounting member. It protrudes in a direction orthogonal to both directions of the direction connecting the front end portion and the rear end portion of 24. The front end surface 24b of the protrusion 24a is slightly inclined so as to approach the inner surface of one side portion of the housing B as it goes rearward. The tip surface 24b may be inclined in the opposite direction, or may be a flat surface extending in parallel with the inner surface of the one side portion.

  The other ends of the pair of links 25 and 26 are rotatably connected to the door-side mounting member 27 via axes S3 and S4 parallel to the axes S1 and S2. As a result, the door side mounting member 27 is supported by the housing side mounting member 24 so as to be rotatable in the horizontal direction. The door-side mounting member 27 is fixed to the left side portion of the back surface of the door C. Therefore, the left side portion of the door C is supported by the left side portion of the housing B via the hinge portion 2 so as to be rotatable in the horizontal direction. As is clear from this, the door-side mounting member 27 and the door C rotate together. Therefore, the same name is given to both rotation positions.

  As shown in FIGS. 3 and 8, when the door C (door-side mounting member 27) rotates to the open position, the link 25 hits the axis S4. Thereby, the open position of the door C is defined. As shown in FIG. 11, when the door C rotates to the closed position, the link 26 hits the shaft S3. Thereby, the closed position of the door C is determined. You may determine the open position and closed position of the door C by abutting the door C on the housing B by other well-known methods, for example.

  Between at least one of the pair of links 25 and 26 and the housing side mounting member 24, a rotation urging means (not shown) made of an elastic member such as a coil spring is provided in a known manner. The rotation urging means is located between a closed position and a predetermined neutral position between the closed position and the open position, for example, a position 45 degrees away from the closed position toward the open position. The door C is urged to rotate toward the closed position via one link and is rotated to the closed position. On the contrary, when the door C is located between the neutral position and the open position, the door C is urged to rotate to the open position side through one link and is rotated to the open position.

  The contact member 4 is detachably fixed to the housing side mounting member 24. The abutting member 4 is disposed on the rear end side from the projecting portion 24a and covers the outer surface of the housing-side mounting member 24 facing the projecting direction of the projecting portion 24a. A contact surface 41 is formed at the tip of the surface facing the right side of the contact member 4 (the protruding direction of the protruding portion 24a). The contact surface 41 is disposed so as to be located on the rearward extension of the front end surface 24b of the protrusion 24a. Therefore, the contact surface 41 is inclined at the same angle in the same direction as the front end surface 24b. Moreover, the leading edge of the abutting surface 41 (the edge adjacent to the protruding portion 24a) is on the left side of the trailing edge of the leading end surface 24b by the distance that the abutting surface 41 is slightly rearward from the leading end surface 24b. positioned. The front end edge of the abutting surface 41 is desirably as close as possible to the front end surface 24b, and is particularly preferably in contact with the rear end edge of the front end surface 24b. In such a case, the front end edge of the contact surface 41 is arranged at the same position in the left-right direction as the rear end edge of the front end surface 24b. The contact surface 41 is disposed at substantially the same position as the tip surface 24b of the protruding portion 24a in the vertical direction.

  The contact member 4 is formed with two through holes 42 and 43 penetrating the contact member 4 in the left-right direction. One through-hole 42 is disposed at the rear end portion of the contact member 4 and faces the bolt B2. The other through-hole 43 is formed in the contact surface 41 and faces the bolt B3. Therefore, a screwdriver tool such as a screwdriver can be inserted from the through holes 42 and 43 and the bolts B2 and B3 can be rotated. Thereby, in the state which attached the contact member 4 to the housing side attachment member 24, the position of the housing side attachment member 24 can be adjusted to the front-back direction and the left-right direction. Needless to say, a through hole may be formed in a portion of the contact member 4 facing the bolt B1, and the bolt B1 may be rotated through the through hole.

  The damper device 3 has a housing 31. The housing 31 is detachably attached to the back surface of the door C by fixing means (not shown) such as bolts. Moreover, one end of the housing 31 (the end located on the housing B side when the door C is positioned at the open position) is detachably engaged with the door-side mounting member 27, thereby positioning the housing 31. Has been.

  The housing 31 is formed with an accommodation hole 31a. The accommodation hole 31a is arranged so as to extend substantially in the front-rear direction when the door C is rotated to the open position. Therefore, when the door C is rotated to the closed position, it extends in the left-right direction. When the door C is rotated to the open position, one end of the accommodation hole 31a located on the housing B side is open, and the other end is closed by the bottom 31b.

  A damper unit 32 is inserted into the accommodation hole 31a from the opening. The damper unit 32 has a cylinder (movable member) 33 and a rod 34. Most of the cylinder 33 excluding one end located on the left side in FIG. 3 is movably accommodated at the end on the opening side of the accommodation hole 31a. The rod 34 is accommodated in the end portion on the bottom 31b side of the accommodation hole 31a. One end of the rod 34 is accommodated in the cylinder 33 so as to be movable in the longitudinal direction. The other end of the rod 34 protrudes from the cylinder 33 and abuts against the bottom 31b of the accommodation hole 31a. Therefore, the rod 34 does not move, and the cylinder 33 moves relative to the rod 34.

  A damper mechanism (not shown) is provided inside the cylinder 33. The damper mechanism unit suppresses the moving speed to a low speed at least when the cylinder 33 moves toward the bottom 31b with respect to the rod 34 (hereinafter referred to as a backward movement). Further, the cylinder 33 moved backward to the bottom 31b side is moved to the initial position shown in FIG. 4 (hereinafter referred to as forward movement).

  A driven member 35 is detachably attached to the cylinder 33. The driven member 35 is formed with a cylindrical portion 35a. This cylinder part 35a is arrange | positioned so that it may extend in the front-back direction when the door C is rotated to an open position. One end portion of the cylindrical portion 35a located on the housing B side is opened, and the other end is closed by the bottom portion 35b. A tip end portion of the cylinder 33 is inserted into the cylindrical portion 35a in a detachable manner. In addition, the cylinder 33 is not only inserted into the cylindrical portion 35a with a predetermined frictional resistance, but also abuts against the bottom 35b. Therefore, the driven member 35 moves forward and backward integrally with the cylinder 33.

  A contact portion 35c is integrally provided on one side portion of the cylindrical portion 35a, that is, the side portion facing the rear end side of the housing B when the door B is rotated to the closed position, as shown in FIG. Yes. As shown in FIG. 9, when the door B (door side mounting member 27) rotates to close from the open position toward the closed position, the contact portion 35 c exceeds the neutral position and reaches a predetermined front contact position ( For example, when reaching a position 30 ° away from the closed position toward the open position), the tip of the contact portion 35c is disposed so as to abut against the tip surface 24b of the protrusion 24a.

  When the door C rotates from the front contact position toward the closed position, the door-side mounting member 27 moves leftward (downward in FIG. 9) and rearward (leftward in FIG. 9). In other words, the door side mounting member 27 is rotatably connected to the housing side mounting member 24 via the pair of links 25 and 26 so as to move in this way. Therefore, when the door C rotates from the front contact position to the closed position side, the contact portion 35c slides on the front end surface 24b toward the rear end side of the housing side mounting member 24, and the contact portion 35c and thus The driven member 35 is relatively moved backward by the distal end surface 24b. As a result, the cylinder 33 is moved backward. At this time, the reverse movement speed of the cylinder 33 is suppressed to a low speed by the damper mechanism.

  When the door C is further closed and rotated from the front contact position and reaches a predetermined rear contact position (contact position), the front end portion of the contact portion 35c becomes the front end edge of the contact surface 41 of the contact member 4. bump into. The front end portion of the contact portion 35c may simultaneously contact the contact surface 41 and the front end surface 24b while the door C is rotated by a predetermined angle from the rear contact position toward the closed position. At the moment when the position reaches the rear contact position, it may be separated from the front end surface 24 b and may contact the contact surface 41. In any case, after the door C reaches the rear contact position when the door C is turned, the contact portion 35c moves from the front end surface 24b to the contact surface 41 and slides on the contact surface 41. In addition, the contact member 35 is moved backward by the contact surface 41, and as a result, the cylinder 33 is moved backward. Of course, also at this time, the reverse movement speed of the cylinder 33 is suppressed to a low speed by the damper mechanism.

  In the furniture A in which the casing B and the door C are rotatably connected by the slide hinge 1, it is assumed that the door C is now located at the open position shown in FIGS. When the door C is rotated from the open position toward the closed position and exceeds the neutral position, the door C is closed and rotated by the rotation urging means of the hinge portion 2. When the door C is closed and rotated to the front contact position, as shown in FIG. 9, the contact portion 35c comes into contact with the front end surface 24b of the protrusion 24a. As a result, the cylinder 33 is moved backward as the door C is closed. At this time, the backward movement speed of the cylinder 33 is suppressed to a low speed by the damper mechanism portion of the damper device 3. When the door C is closed and rotated from the front contact position to the rear contact position, the contact portion 35c is transferred from the front end surface 24b onto the contact surface 41. At this time, since the contact surface 41 is located on the rearward extension of the tip surface 24b, the contact portion 35c can smoothly transfer from the tip surface 24b to the contact surface 41. Thereafter, the abutting portion 35c slides backward on the abutting surface 41 as the door C is closed and rotated. Here, although the through hole 43 is formed in the contact surface 41, the contact portion 35 c slides across the through hole 43. Therefore, smooth sliding of the contact portion 35 c is not hindered by the through hole 43. Further, as the door C is closed and rotated, the contact portion 35c is moved backward, and as a result, the cylinder 33 is moved backward. At this time, the backward moving speed of the cylinder 33 is suppressed to a low speed until the door C reaches the closed position by the damper mechanism portion of the damper device 3. Therefore, a high-class feeling can be given to furniture. Further, even if the door C reaches the housing B when it reaches the closed position, it is possible to prevent a large collision sound from being generated.

  When the door C is rotated from the closed position to the open position, the contact portion 35c slides on the contact surface 41 toward the front end side while the door C rotates from the closed position to the rear contact position. To do. Accordingly, the cylinder 33 and the driven member 35 are moved forward by the damper mechanism. Until the door C passes the rear contact position and reaches the front contact position, the contact portion 35c slides on the front end surface 24b, and the cylinder 33 and the driven member 35 further move forward. When the door C reaches the front contact position, the contact member 35 and the cylinder 33 return to the initial position. When the door C exceeds the front contact position, the contact portion 35c is separated from the front end surface 24b. Thereafter, when the door C exceeds the neutral position, the door C is rotated to the open position by the rotation urging means of the hinge portion 2.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above embodiment, the rod 34 is abutted against the bottom 31b of the accommodation hole 31a, but the direction of the damper unit 32 may be reversed and the cylinder 33 may be abutted against the bottom 31b. In this case, the rod 34 becomes a movable member that moves forward and backward.
Further, in the above-described embodiment, the cylinder (movable member) 33 is abutted against the tip surface 24b and the contact surface 41 via the driven member 35. However, the cylinder 33 is opposed to the tip surface 24b and the contact surface 41. You may hit it directly. Of course, when the rod 34 is a movable member, the rod 34 may directly abut against the tip surface 24b and the contact surface 41.
In the above-described embodiment, when the door C reaches the front contact member from the open position, the contact portion 35c of the driven member 35 comes into contact with the tip surface 24b of the protruding portion 24a. The member 35 may be caused to abut only against the abutting surface 41 of the abutting member 4 without abutting against the front end surface 24b. In that case, it is not necessary to arrange the contact surface 41 on the rearward extension of the distal end surface 24b. For example, the contact surface 41 may be disposed away from the distal end surface 24b in the projecting direction of the protruding portion 24a. Good. However, when the abutting portion 35c is abutted against the front end surface 24b, the door closing rotation speed is equal to the angle at which the door C rotates while the abutting portion 35c slides on the front end surface 24b. It is possible to increase the angle range that suppresses the low speed. Therefore, it is desirable that the abutting portion 35c be abutted against the tip surface 24b.
Furthermore, in the above-described embodiment, the entire contact surface 41 is disposed on the extension of the tip surface 24b of the protruding portion 24a, but the driven member 35 smoothly transfers from the tip surface 24b to the contact surface 41. As long as the tip of the contact surface 41 is disposed on the extension of the tip surface 24b, the other part of the contact surface 41 may be removed from the extension of the tip surface 24b. For example, the contact surface 41 may be inclined in the direction opposite to the tip surface 24b so as to be parallel to the inner surface of one side portion of the housing or to be separated from the inner surface of the one side portion as it goes rearward.
