Description

  The present invention relates to a damper device suitable for use in a hinge such as a slide hinge and a damper-equipped hinge having the damper device.

  Generally, the slide hinge includes a first fixing member, a main body member detachably attached to the first fixing member, and a second fixing member rotatably connected to the main body member via a pair of links. have. The first fixing member is attached to the housing, and the second fixing member is attached to the door. As a result, the door is attached to the housing so as to be capable of opening and closing through the slide hinge. Moreover, when at least one of the pair of links connecting the main body member and the second fixing member is located between the closed position and a position away from the door by a predetermined angle (for example, 30 °). Then, the door is urged to rotate toward the closed position. As a result, the door is rotated to the closed position and maintained at the closed position.

  When the door reaches the closed position, the door is accelerated at high speed by the slide hinge. For this reason, there is a problem in that a large collision sound is generated when the door rotates from the open position to the closed position and hits the housing.

  In order to prevent such a problem, the following Patent Document 1 proposes a slide hinge with a damper including a damper device. In this slide hinge with a damper, a damper device is attached to a main body member of the slide hinge. The damper device includes a holder attached to the main body member, a movable member provided to the holder so as to be linearly movable, and a damper mechanism that keeps the moving speed of the movable member low, and the door is in the open position. When the door is rotated from the side toward the closed position and reaches a contact position in front of the closed position by a predetermined distance, the door comes into contact with the movable member. Therefore, while the door rotates from the contact position to the closed position, the rotation speed of the door is suppressed to a low speed. Thereby, it is prevented that a loud collision sound is generated when the door collides.

The other ends of the pair of links 25A and 25B are connected to the door-side fixing member 26 so as to be rotatable in the horizontal direction about an axis extending in the vertical direction. Thereby, the door side fixing member 26 is connected to the main body member 24 so as to be rotatable in the horizontal direction. As shown in FIG. 2, the door-side fixing member 26 is fixed to the door B. As a result, the door B is connected to the housing A through the hinge portion 2 so as to be rotatable in the horizontal direction.

  At least one of the pair of links 25A and 25B has elasticity, and the door B is located between the closed position and a neutral position separated from the open position by a predetermined angle (for example, 30 °). When doing so, the door B is urged to rotate toward the closed position. Then, the door B is rotated to the closed position by the rotation biasing force and is maintained at the closed position. Further, the one link rotates and biases the door B toward the open position when the door B is located between the neutral position and the open position. Then, the door B is rotated to the open position by the rotation biasing force and is maintained at the open position. Of course, as with other known slide hinges, a pair of links may be rigid, and a biasing means such as a coil spring may be provided between the one link and the connecting member.

  Next, the damper part 3 will be described. The damper part 3 includes a holder 31 and a damper assembly 32 as shown in FIGS. 11 and 12 in particular.

  The holder 31 is formed by molding a hard resin and is formed in a substantially rectangular parallelepiped shape. The holder 31 is arranged to face the inner surface of the left side portion of the housing A with the longitudinal direction thereof directed in the front-rear direction and the width direction thereof directed in the up-down direction and the thickness direction directed in the left-right direction. ing. The holder 31 may be formed of a material other than resin, or may be formed in a shape other than a rectangular parallelepiped.

  The end surface of the holder 31 facing the inner surface on the left side of the housing A, that is, the end surface facing left (hereinafter referred to as the lower surface, and the surface facing right) is referred to as the upper surface. An accommodation recess 31a extending toward the top is formed. The housing recess 31 a is disposed in a range from the center in the up-down direction of the holder 31 to the lower end. The main body member 24 is accommodated in the accommodating recess 31a except for its front end. In particular, as shown in FIG. 8, the housing recess 31 a is set to a size such that a gap S is formed between the inner surface and the outer surface of the main body member 24. The size of the gap S is set so that the main body member 24 does not contact the inner surface of the housing recess 31a even if the main body member 24 is adjusted to the maximum in the vertical and horizontal directions and the front and rear directions. Yes. The accommodating recess 31a may be sized to accommodate substantially the entire body member 24.

  On the side surface located on the lower side of the holder 31, a protruding portion 31 b that protrudes downward is formed. The protruding portion 31b is disposed so as to face the lower end portion of the substrate portion 21a in the horizontal direction. The surface of the protruding portion 31b that faces the substrate portion 21a is flush with the lower surface of the holder 31, and a concave portion 33 is formed on the surface. The upper end of the recess 33 communicates with the housing recess 31a. The recess 33 accommodates a lower end portion of the substrate portion 21 a that protrudes downward from the main body member 24. The inner side surface of the recess 33 is substantially in contact with the front, lower, and rear side surfaces of the lower end portion of the substrate portion 21a. Thus, the holder 31 is positioned with respect to the lower end portion of the substrate portion 21a.

  In particular, as shown in FIG. 9, a first engagement convex portion 33 b is formed on the lower end portion (left end portion) in FIG. 9 of the inner side surface 33 a located on the front side (left side in FIG. 9) of the concave portion 33. The first engagement convex portion 33b passes through a notch 21e (see FIGS. 11 and 12) formed on the front side surface of the lower end portion of the substrate portion 21a, and is below the substrate portion 21a (the lower side in FIG. 9). It enters and engages with the lower surface of the substrate portion 21a. A second engagement convex portion 33d is formed at the lower end portion in FIG. 9 of the inner side surface 33c located on the rear side (right side in FIG. 9) of the concave portion 33. The second engaging convex portion 33d enters the lower side of the substrate portion 21a through a notch (not shown) formed on the rear side surface of the lower end portion of the substrate portion 21a, and engages with the lower surface of the substrate portion 21a. Match. The first and second engaging convex portions 33b and 33d engage with the lower surface of the substrate portion 21a, while a contact portion (not shown) formed on the inner surface of the concave portion 33 abuts against the upper surface of the substrate portion 21a. The first and second engaging protrusions 33b and 33d and the contact portion sandwich the substrate portion 21a in the vertical direction of FIG. Thereby, the protrusion part 31b is connected and fixed to the lower end part of the board | substrate part 21a, and the lower part of the holder 31 is connected and fixed to the lower end part of the board | substrate part 21a by extension.

  In particular, as shown in FIGS. 8 and 17, a recess 34 is formed on the lower surface of the holder 31. The recess 34 is disposed above the housing recess 31a. The lower end of the recess 34 (the right end in FIG. 8) communicates with the housing recess 31a. The concave portion 34 accommodates the upper end portion of the substrate portion 21 a protruding upward from the main body member 24. The inner side surface of the recess 34 is substantially in contact with the front, upper, and rear side surfaces of the upper end portion of the substrate portion 21a. Accordingly, the holder 31 is positioned with respect to the upper end portion of the substrate portion 21a.

  On the inner side surface 34a on the front side of the concave portion 34, an engaging convex portion 34b corresponding to the first engaging convex portion 33b of the concave portion 33 is formed. The engaging protrusion 34b enters the lower side of the substrate portion 21a through a notch (see FIG. 17) formed on the front side surface of the upper end portion of the substrate portion 21a, and engages with the lower surface of the substrate portion 21a. Yes. A contact portion corresponding to the contact portion formed in the recess 33 is formed on the inner surface of the recess 34. By sandwiching the upper end portion of the substrate portion 21a by the contact portion and the engaging convex portion 34b, the upper portion of the holder 31 is connected and fixed to the upper end portion of the substrate portion 21a.

  The lower portion of the substrate portion 21a is fitted into the concave portion 33 to position the lower portion of the holder 31 with respect to the substrate portion 21a, and the lower portion of the holder 31 is formed by the first and second engaging convex portions 33b and 33d and the contact portion. As is clear from the fact that the lower end portion of the substrate portion 31 is connected and fixed, the lower portion (one end portion) of the holder 31 is placed on the substrate by the concave portion 33, the first and second engaging convex portions 33b and 33d, and the contact portion. An attachment portion for attaching to the lower end portion of the portion 21a is configured. Further, the upper end portion of the substrate portion 21a is fitted into the concave portion 34 so that the upper portion of the holder 31 is positioned with respect to the substrate portion 21a, and the upper portion of the holder 31 is placed on the substrate portion 21a by the engaging convex portion 34b and the contact portion. As is apparent from the fact that it is connected and fixed to the upper end portion, an attachment portion for attaching the upper portion (the other end portion) of the holder 31 to the upper end portion of the substrate portion 21a by the concave portion 34, the engaging convex portion 34b and the contact portion. Is configured. That is, in this embodiment, in order to attach the holder 31 to the housing side fixing member 21, attachment portions are formed at both upper and lower ends of the holder 31.

  The rear side wall portion 31c of the protruding portion 31b formed with the second engaging convex portion 33d is rotated in the directions of arrows A and B in FIG. 9 by elastic deformation of the base end portion (upper end portion in FIG. 9). Is possible. When the knob portion 31d formed on the outer surface of the rear side wall portion 31c is pushed upward in FIG. 9, the rear side wall portion 31c rotates in the arrow A direction. Accordingly, the second engaging convex portion 33d moves to the right (backward) in FIG. When the rear side wall portion 31c is further rotated, the second engagement convex portion 33d is separated rearward from the substrate portion 21a, and the engagement between the second engagement convex portion 33d and the substrate portion 21a is released. In this state, the holder 31 can be rotated in the counterclockwise direction of FIG. 9 with the first engaging protrusions 33b and the engaging protrusions 34b and the board portions 21a as the center. Then, after rotating the holder 31 counterclockwise until the second engaging convex portion 33d moves upward from the substrate portion 21a in FIG. 9, when the holder 31 is moved leftward in FIG. The engagement convex portion 33b and the engagement convex portion 34b are separated from the substrate portion 21a forward (leftward in FIG. 9), and the engagement is released. As a result, the engagement between the holder 31 and the substrate portion 21 a is released, and the holder 31 can be detached from the housing side fixing member 21.

  Conversely, when the holder 31 is fixed to the housing-side fixing member 21, the first engaging convex portion 33b and the engaging portion 33 are engaged with the rear end portion of the holder 31 being slightly spaced upward from the substrate portion 21a in FIG. The convex portions 34b are engaged with the substrate portions 21a, respectively. Thereafter, the holder 31 is rotated in the clockwise direction in FIG. 9 with the first engaging convex portion 33b, the engaging convex portion 34b, and the engaging portions of the substrate portion 21a as the center. Then, the inclined surface 33e formed continuously downward from the second engaging protrusion 33d in FIG. 9 abuts against the rear side surface of the lower end portion of the substrate portion 21a. In this state, when the holder 31 is further rotated in the same direction, the rear side wall portion 31c is rotated in the direction of arrow A in FIG. 9 by the inclined surface 33e. Thereafter, when the holder 31 is further rotated, the second engaging convex portion 33d gets over the substrate portion 21a and faces the notch. Then, the rear side wall portion 31c returns to its original state due to its own elasticity, and the second engagement convex portion 33d engages with the lower surface of the substrate portion 21a. Thus, the holder 31 is attached to the housing side fixing member 21 in a fixed state.

  Note that the top plate portion of the holder 31 is formed with two through holes 31f and 31g reaching from the upper surface to the housing recess 31a. As is clear from FIGS. 3 and 10, one through hole 31f is for inserting a screwdriver such as a screwdriver for rotating the adjusting bolt 28, and the through hole 31g is a bolt 27A. And a screwdriver such as a screwdriver for rotating the adjustment bolts 29, respectively.

  In particular, as shown in FIGS. 7, 8, 11, 12, 17, and 18, the holder 31 is formed with a mounting hole 31 e that extends substantially horizontally from the front to the rear. The mounting hole 31e is arranged so that the central portion in the vertical direction (left-right direction in FIG. 8) is positioned substantially the same in the vertical direction as the central portion in the vertical direction of the engaging convex portion 34b.

  A damper assembly 32 is inserted into the mounting hole 31e so as to be detachable. The damper assembly 32 has a casing (movable member) 35 and a rod 36. A front end portion of a rod 36 is inserted into the casing 35 so as to be movable in the front-rear direction. The rear end portion of the rod 36 protrudes rearward from the rear end surface of the casing 35. The rod 36 is movable between an initial position shown in FIG. 12 with respect to the casing 35 and a limit position that is a predetermined distance away from the initial position.

  Inside the casing 35, a damper mechanism and an urging means (both not shown) are provided. The damper mechanism prevents the rod 36 from moving at high speed in the front-rear direction with respect to the casing 35 and suppresses the moving speed to a low speed. The urging means is made of an elastic member such as a coil spring and urges the rod 36 in the direction from the limit position toward the initial position, that is, backward. Therefore, the rod 36 is located at the initial position shown in FIG. 12 unless an external force in the axial direction acts on the rod 36.

  In particular, as shown in FIGS. 11 and 12, a casing 35 is slidably inserted into the mounting hole 31e. In this case, the casing 35 is inserted into the mounting hole 31e with the rod 36 first, and the rear end of the rod 36 abuts against the bottom surface of the mounting hole 31e. When the rod 36 is located at the initial position, the front end portion of the casing 35 protrudes forward from the mounting hole 31e. Then, when the door B is closed and rotated from the open position side to a front contact position by a predetermined angle (for example, 20 °) of the initial position, the door B hits the front end surface of the casing 35. When the door B is further closed and rotated, the casing 35 is pushed backward, and the rod 36 enters the casing 35. When the door B rotates to the closed position, the rod 36 enters the casing 35 to a position slightly before the limit position, and the casing 35 moves rearward by that amount. Also at this time, the front end portion of the casing 35 projects forward from the mounting hole 31e.

  It is assumed that the door B is now closed in the case A and the door B in which the damper hinge 1 having the above-described configuration is used. At this time, the rod 36 is located at a position slightly before the limit position from the initial position, and the casing 35 is moved rearward by that amount. In this state, the urging means of the damper portion 3 urges the door B in the opening direction through the casing 35, but at least one rotational urging force of the pair of links 25 </ b> A and 25 </ b> B of the hinge portion 2 is the damper portion 3. It is larger than the biasing force of the biasing means. Therefore, the door B is maintained in the closed position.

  It is assumed that the door B is opened from the closed position to the open position, for example. Then, the rod 36 is returned to the initial position by the biasing means. Accordingly, the casing 35 is moved forward. At this time, the moving speed of the rod 36 and the casing 35 is suppressed to a low speed by the damper mechanism.

  When the door B is closed and rotated from the open position, when the door B reaches a predetermined neutral position, the door B is thereafter closed and rotated by the rotation biasing force of the hinge portion 2. The door B is rotated at a high speed by the hinge portion 2 until reaching the contact position from the neutral position. When the door B rotates to the contact position and hits the casing 35, the rotation speed of the door B is suppressed to a low speed by the damper mechanism of the damper portion 3. Then, the door B hits the housing A in a low speed state. Therefore, it is possible to prevent a large collision sound from being generated when the door B hits the casing A.

In that case, a rotation urging means for urging the door in the closing direction is provided between the housing and the door. Then, the damper device prevents the door from colliding with the casing vigorously by the rotation urging means.
The hinge damper device according to the present invention can be applied not only to the slide hinge but also to other hinges.
In the above-described embodiment, the casing 35 of the damper assembly 32 is a movable member that abuts against the door B. However, the rod 36 of the damper assembly 32 may be a movable member that abuts against the door B. In that case, the casing 35 is abutted against each bottom portion of the mounting hole 31 e of the holder 31.
Further, in the above-described embodiment, the casing 31, the rod 36, the damper mechanism 32 having the damper mechanism and the urging means are attached to the holder 31, but the movable member is directly provided on the holder 31, and this movable member A damper mechanism and a biasing means may be provided between the holder 31 and the holder 31.
