Description

  The present invention relates to a hinge with a damper function for supporting a door so that it can be opened and closed in an opening, and suppressing a door closing speed when the door is closed.

2. Description of the Related Art Conventionally, a hinge with a damper function is known in order to suppress a door closing speed in a door that is swingably supported by a hinge on one side of an opening such as a house entrance.
Such a hinge with a damper function suppresses the closing speed of the door when the door moves to the closing position with respect to the opening, and slowly closes the door at a closing speed of a certain speed or less.
This prevents human fingers from being caught between the door and the opening when the door is closed, and generates a loud sound when the door collides with a fixed part near the opening, for example, the frame around the opening. To prevent it.

As a hinge with a damper function, a hinge having a so-called hydraulic damper is known.
Such a hinge with a hydraulic damper can surely suppress the door closing speed based on the action of the hydraulic damper, and can realize a door closing speed below a certain speed.

However, the hydraulic damper is large in itself, and in order to provide the hydraulic damper in the hinge, the hinge is also enlarged.
Furthermore, the space occupied by the hydraulic damper in the hinge is large, and the degree of freedom of arrangement of the mechanism for adjusting the position in the triaxial direction when the hinge is attached is reduced.
Therefore, for example, the direction of the position adjustment screw may not coincide with the direction to be adjusted, and it is difficult to perform intuitive position adjustment.

  In view of the above, the present invention has an object to provide a hinge with a damper function that can be configured in a small size with a simple configuration and that can be easily and intuitively adjusted in position.

  According to the configuration of the present invention, the above object is a hinge with a damper function that supports the door so as to be swingable through the opening and suppresses the door closing speed when the door is closed, and is attached to one side of the opening. Provided in the base mounting portion, a braking member that moves in a direction perpendicular to the swing axis of the door within the base portion, a door mounting portion that is attached to the door and is supported so as to be pivotable with respect to the base portion, and the door mounting portion And a connecting member that advances and retracts the braking member in the base portion when the door is opened and closed.The base portion has two sliding surfaces facing each other so as to sandwich the moving path of the braking member. A pair of pushers that are urged toward the two sliding surfaces from the main body that slides along the moving path. The main body of the brake member and each pusher are configured such that the main body of the brake member swings the door. Two as you move towards the axis Each pusher follows the shape of the taper when the brake member approaches the moving path toward the swing axis of the door via the connecting member in conjunction with the closing of the door. This is achieved by a hinge with a damper function, which is pressed against the corresponding sliding surface of the base portion, and the closing of the door is suppressed by the frictional force between the two pushers and the two sliding surfaces.

  In the hinge with a damper function according to the present invention, the main body portion of the braking member is preferably urged by an elastic member toward the swing shaft of the door.

  The hinge with a damper function according to the present invention is preferably such that the door is pivotally supported via a link with respect to the opening, and the door swings around the swing axis via the link when the door is closed. Thus, the connecting member moves the braking member.

  In the hinge with a damper function according to the present invention, preferably, the connecting member is provided with a pusher pin extending in parallel with the swing shaft of the door on the brake member side, and the main body portion of the brake member is provided on the main body portion of the brake member. And a slit extending in a direction different from the moving direction of the swinging shaft of the door and the braking member, and a pusher pin is engaged with the slit.

  In the hinge with a damper function according to the present invention, preferably, the base portion includes a movable portion that defines a moving path of the braking member, and the movable portion is positionally adjustable in three axial directions with respect to the base portion.

  In the hinge with a damper function according to the present invention, the movable part preferably includes a first adjustment screw disposed on an axis extending in at least one adjustment direction, and the movable part rotates the first adjustment screw. By moving it, the position can be adjusted by parallel movement in the corresponding axial direction.

  The hinge with a damper function according to the present invention is preferably configured such that the movable portion is pivotally supported on one side so as to be swingable in at least one adjustment direction and disposed on an axis extending in the adjustment direction on the other side. An adjustment screw is provided, and the movable portion can be adjusted in position by swinging in the corresponding axial direction by rotating the second adjustment screw.

According to the above configuration, when the door is closed, the door mounting portion turns as the door is closed, and the braking member moves toward the swing axis of the door within the base portion by the connecting member.
At this time, due to the movement of the braking member, each pusher is pressed against the corresponding sliding surface by the main body portion of the braking member based on the inclination of the taper. Therefore, the frictional force with respect to the sliding surface of each pusher increases, and the moving speed is suppressed.
Accordingly, the swinging speed of the door mounting portion and the door is suppressed via the connecting member, and it is possible to reliably prevent the fingers and the like from being caught between the door and the opening when the door is closed. Generation of impact sound due to collision with the frame around the opening can be prevented.

On the other hand, when the door is opened, the door mounting portion turns as the door is opened, and the braking member moves away from the swing shaft of the door within the base portion by the connecting member.
At this time, due to the movement of the braking member, each pusher moves away from the corresponding braking surface based on the inclination of the taper. Therefore, the frictional force with respect to the sliding surface of each pusher decreases, and the braking member moves with a small force.
Thereby, a door attachment part and a door move easily to a full open position via a connection member, and are opened.

In this case, in order to suppress the closing speed of the door, the conventional hydraulic damper is not used, but the sliding damper made of the above-described braking member is used, so the damper function is small and low cost. A hinge with a hinge can be constructed.
Further, the pair of pushers are urged against the sliding surfaces facing each other, so that not only the door closing speed is suppressed, but also the braking member is positioned and adjusted with respect to the base portion. Therefore, the number of parts can be reduced, and the overall part cost and assembly cost can be reduced.

  When the door is pivotally supported with respect to the opening via a link, when the door is closed, the door swings around the swing shaft via the link, so that the connecting member smoothly moves to the braking member. Press.

  The connecting member is provided with a pusher pin extending parallel to the swing shaft of the door on the brake member side, and the main body portion of the brake member is provided on the main body portion of the brake member, and the movement of the swing shaft of the door and the brake member When the pusher pin is engaged with the slit, and the pusher pin is guided along the slit, the connecting member moves the brake member through the pusher pin. Move it securely.

  The base portion includes a movable portion that defines a moving path of the braking member, the movable portion can be adjusted in position in three axial directions with respect to the base portion, and the movable portion is on an axis extending in at least one adjustment direction. If the movable part can be moved and adjusted in the corresponding axial direction by rotating the first adjustment screw, the first adjustment screw is adjusted. Since the direction matches the adjustment direction of the movable part with respect to the base part, the position adjustment of the movable part with respect to the base part can be performed intuitively.

As described above, according to the present invention, it is possible to provide a hinge with a damper function that can be configured in a small size with a simple configuration and can be easily and intuitively adjusted in position.

The attachment portion 21 is made of, for example, a sheet metal or the like, and is fixed to the opening portion 11 with a fixing screw 25 in a state where the flat bottom surface is in contact with the surface of the opening portion 11 as shown in FIG.
Further, the mounting portion 21 includes engaging portions 21a and 21b provided at both ends in the X direction, and bearing portions 21c rising from both sides in the center in the X direction.

The first movable portion 22 is made of, for example, a sheet metal or the like, and is placed on the bottom surface of the attachment portion 21, and both ends 22 a and 22 b in the X direction are engaged portions 21 a and 21 b of the attachment portion 21. The movement in the X direction and the Z direction in FIG. 1 is restricted.
The first movable portion 22 is selected such that the width in the Y direction is narrower than the width of the bottom surface of the mounting portion 21.
Thus, the first movable portion 22 is supported on the bottom surface of the attachment portion 21 so as to be slidable in the Y direction.

Further, the first movable portion 22 includes a female screw portion 22c extending in the Y direction near the center in the X direction.
The first adjustment screw 26 is inserted into and screwed into the female screw portion 22c through the bearing portion 21c of the mounting portion 21.
One end of the first adjusting screw 26 is locked to the outside of both side surfaces of the attachment portion 21 by a screw head 26a and the other end by a so-called E ring 26b.
Thereby, by rotating the first adjustment screw 26, the first movable portion 22 is based on the screw engagement between the screw portion of the first adjustment screw 26 and the female screw portion 22 c of the first movable portion 22. Are translated in the Y direction to adjust the position in the Y direction.

The second movable portion 23 is composed of a bottom portion 23a made of, for example, die casting, and a cover portion 23b made of, for example, a sheet metal that covers the upper surface of the bottom portion 23a from both sides and above, as shown in FIG. An engaging portion 23c provided on the lower surface of the front end in the X direction of the bottom portion 23a is engaged with the engaging portion 21a of the mounting portion 21 from the front side.
The cover portion 23b defines a hollow portion 23j that opens toward the front side in the X direction above the bottom portion 23a.
Here, both side surfaces of the cover portion 23b are formed smoothly as sliding surfaces 23d for a braking member, which will be described later.

Further, the second movable portion 23 includes a female screw portion 23e extending in the Z direction in the vicinity of the rear end thereof.
A second adjustment screw 27 is inserted into and screwed into the female screw portion 23e from above in FIG.
The second adjustment screw 27 has a head in the upper direction in the Z direction that is rotatably locked to the upper surface of the frame 24 described later.
Thereby, by rotating the second adjustment screw 27, the frame 24 is moved to the second position based on the screwing of the screw portion of the second adjustment screw 27 and the female screw portion 23e of the second movable portion 23. The position is adjusted in the Z direction by moving in the Z direction with respect to the movable portion 23.

Furthermore, the second movable portion 23 includes a lever 23g supported at the rear end so as to be swingable around a shaft 23f extending in the Y direction.
The lever 23g is given right-handedness in FIG. 2 by a spring (not shown).
The lever 23g has a hook portion 23h, and the hook portion 23h engages with an engagement portion 21b provided at the rear end of the attachment portion 21 from the lower rear side.
Accordingly, the second movable portion 23 is detachably attached to the attachment portion 21 by the engagement portion 23c of the bottom portion 23a and the hook portion 23h of the lever 23g engaging with the attachment portion 21.
When the lever 23g is rotated counterclockwise against the tension of the spring in FIG. 2, the hook portion 23h is disengaged from the engaging portion 21b of the attachment portion 21, and the second movable portion 23 is detached from the first movable portion 22. be able to.

The frame 24 is made of, for example, a sheet metal or the like, and is fitted so as to cover the second movable portion 23 from above and from both sides in the Y direction.
Here, as described above, in the frame 24, the second adjustment screw 27 is locked in the engagement hole 24b provided near the rear end of the upper surface 24a, and the second adjustment screw 27 is moved to the second movable screw 24b. It is attached to the second movable portion 23 by being screwed into the female screw portion 23e of the portion 23.
The engagement hole 24 b extends in the X direction, and the front end thereof is formed as an enlarged portion that is larger than the head of the second adjustment screw 27.

Further, as shown in FIG. 3, the frame 24 includes a pair of projecting portions 24 c that protrude forward in the X direction from both sides in the Y direction.
Each overhang portion 24c is provided with a shaft hole 24d in the vicinity of the upper end thereof and a shaft hole 24e on the lower side behind the shaft hole 24d.
A shaft 24f is inserted through the shaft hole 24e, and this shaft 24f passes through a through hole 23i provided in the front end of the second movable portion 23 and extending in the Y direction.
Here, the through hole 23i has an elongated cross-sectional shape in the X direction, and the shaft 24f is movable in the X direction within the through hole 23i.
Thus, the frame 24 can move in the X direction with respect to the second movable portion 23 and can swing around the shaft 24f.

Further, the frame 24 includes a falling portion 24g whose rear end in the X direction extends downward, and a female screw portion 24h is provided on the falling portion 24g.
A third adjustment screw 28 is screwed into the female screw portion 24 h, and the tip of the third adjustment screw 28 is in contact with the rear wall of the second movable portion 23.
Accordingly, the second movable portion 23 is moved and adjusted in the X direction by the rotation of the third adjustment screw 28.

As shown in FIG. 5, the braking member 30 includes a main body portion 31 and a pair of pushers 32 provided on both side surfaces in the Y direction with respect to the main body portion 31.
The main body 31 is accommodated in the hollow portion 23j of the second movable portion 23 so as to be slidable in the X direction, and is moved forward in the X direction by the compression coil spring 33 accommodated in the closed end of the hollow portion 23j. On the other hand, it is energized as indicated by reference numeral F1.

The main body 31 includes an extension 31a whose front end in the X direction extends forward, and a slot 31b at the front end 7 in the X direction.
As shown in FIG. 6, the slot 31b includes a linear portion 31c that extends straight in the upper Z direction, and an arc-shaped portion 31d that extends obliquely from the lower end of the linear portion 31c toward the rear in the X direction. Become.
The arcuate portion 31d is formed along an arc centered on the shaft 24f when the braking member 30 is positioned rearward in the X direction within the hollow portion 23j of the second movable portion 23.

Further, the main body 31 includes a recessed portion 31 e for receiving the pusher 32. Each of the recessed portions 31e has a taper so as to become shallower toward the rear in the X direction, and is formed at a predetermined angle, for example, an inclination angle of 25 degrees.
Each recessed part 31e has a through hole 31f that penetrates a back-facing slope in the Y direction.

On the other hand, each pusher 32 has an outer surface corresponding to the side surface of the main body 31 and a taper corresponding to the taper of the concave 31e in a state of being accommodated in the corresponding concave portion 31e of the main body 31, respectively. And having an inner surface.
Further, each pusher 32 has a convex portion 32a protruding in the X direction near the center of the inner side surface.
As a result, each pusher 32 is loaded into the recessed portion 31e with the second compression coil spring 34 interposed in the through hole 31f of the main body portion 31.
Accordingly, each pusher 32 always has a second compression coil spring 34 in the corresponding recessed portion 31e, as indicated by reference numeral F2 in FIG. 7, always in a direction away from each other in the Y direction, that is, as indicated by reference numeral F2. It is energized by.
Thus, when the braking member 30 is inserted into the hollow portion 23j of the second movable portion 23 constituting the base portion 20, each pusher 32 is against the inner surface on both sides of the hollow portion 23j, that is, the sliding surface 23d. It is urged by the compression coil spring 34 and comes into contact therewith.

Thus, when the braking member 30 accommodated in the hollow portion 23j of the second movable portion 23 moves rearward in the X direction within the hollow portion 23j, as shown in FIG. The pusher 32 abuts against the sliding surface 23d of the hollow portion 23j due to the tension of the second compression coil spring 34, and a frictional force is generated. Enter the part 31e. At this time, the distance between the outer surfaces of each pusher 32 is W.
On the other hand, when the braking member 30 moves toward the front in the X direction in the hollow portion 23j, each pusher 32 is hollow by the tension of the second compression coil spring 34 as shown in FIG. Since the frictional force is generated by abutting against the sliding surface 23d of the portion 23j, when the braking member moves by a distance d, for example, when the braking member moves by a distance d, the frictional force is generated from the recessed portion 31e along the taper. Projects outward by Δw. At this time, the distance between the outer surfaces of each pusher 32 is (W + Δw). Therefore, the frictional force on the sliding surface 23d of each pusher 32 further increases, and the movement of the braking member 30 is suppressed.

The door mounting portion 40 includes a main body portion 41 formed in a hollow rectangular parallelepiped shape, and flange portions 42 that extend from the open end of the main body portion 41 to both sides in the Y direction.
The main body 41 is made of, for example, a sheet metal or the like, and has two shafts 41a and 41b extending in the Y direction at the rear in the X direction in FIG.
The shaft 41a is disposed near the open end in a region near the rear edge of the main body 41, and the shaft 41b is disposed near the bottom surface of the main body 41 on the front side of the shaft 41a.

The flange portion 42 is configured integrally with the main body portion 41 and has a screw hole 42a.
As a result, the main body portion 41 of the door attachment portion 40 is accommodated in a recessed portion provided in advance in the door 11, and an attachment screw (not shown) is inserted into the screw hole 42 a of the flange portion 42 and screwed in. The door mounting portion 40 is fixed at a predetermined position of the door 11.

The connecting member 50 is composed of two links 51 and 52.
One end of the link 51 is connected to a shaft 41a provided on the main body 41 of the door mounting portion 40, and the other end has two shaft holes 51a and 51b as shown in FIG. .
The shaft hole 51 a is disposed on the lower side in the Z direction, and the shaft 24 f of the frame 24 is inserted therethrough and supported rotatably with respect to the frame 24.
The shaft hole 51b is disposed slightly rearward in the X direction than the shaft hole 51a, and the pusher pin 53 is inserted as shown in FIG. The pusher pin 53 engages with a slot 31 b provided in the main body 31 of the braking member 30.

As a result, when the link 51 rotates counterclockwise around the shaft 24f in FIG. 2, the pusher pin 53 first slides along the arcuate portion 31d of the slot 31b, and then the pusher pin 53 moves to the linear portion 31c of the slot 31b. Then, the link 51 rotates counterclockwise while moving the braking member 30 forward in the X direction.
The main body 31 of the braking member 30 is also connected to the frame 24 via a pusher pin 53, a link 51, and a shaft 24f, whereby the frame 24 is also urged forward in the X direction by the compression coil spring 33. The Therefore, the tip of the third adjustment screw 28 at the rear end of the frame 24 is always in contact with the rear wall of the second movable portion 23 based on the biasing force of the compression coil spring 33.

  The link 52 connects the door 11 and the opening 12 and pivotally supports the door 12 so as to be swingable with respect to the opening 12. One end of the link 52 is provided on the main body 41 of the door mounting portion 40. The shaft 52 a is connected to the shaft 41 b and has the other end inserted into the shaft hole 24 d of the frame 24, and can swing around the shaft 52 a extending in the Y direction with respect to the frame 24.

The hinge 10 with a damper function is configured as described above, and operates as shown in FIG. 9 when the door 12 is closed from the fully opened state.
That is, first, in the fully open state (opening degree of 95 degrees) shown in FIG. 9A, the pusher pin 53 inserted into the shaft hole 51b of the link 51 is the lower end of the slot 31b provided in the bottom 31 of the braking member 30. The braking member 30 is located rearward in the X direction within the hollow portion 23j of the second movable portion 23.
From this state, when the door 12 is closed, the link 52 first rotates clockwise around the axis 52a and the link 51 rotates clockwise around the axis 24f. In the state where the door 12 is half-opened to the opening degree of 65 degrees, the pusher pin 53 slides along the arcuate portion 31d of the slot 31b, so that the braking member 30 remains stationary.

When the door 12 is closed to a half-open state with an opening of 35 degrees, as shown in FIG. 9C, the door 12 rotates clockwise around the axis 41b, and the link 52 rotates counterclockwise around the axis 52a, The link 51 rotates clockwise around the axis 24f.
As a result, the pusher pin 53 slides by a distance d1 to a position past the uppermost portion of the arc-shaped portion 31d of the slot 31b, that is, the boundary with the linear portion 31c. Accordingly, the braking member 30 moves slightly forward in the X direction.

After that, when the door 12 is closed to the fully closed state (opening degree 0 degree), as shown in FIG. 9D, the door 12 is further rotated clockwise around the shaft 41b, and the link 52 is connected to the shaft 52a. Further, the link 51 is further rotated to the right around the axis 24f.
Thereby, the pusher pin 53 slides on the linear portion 31c of the slot 31b. At this time, the pusher pin 53 moves the main body portion 31 of the braking member 30 by a distance d2 toward the front in the X direction based on the shape of the linear portion 31c.

Here, when the braking member 30 tries to move forward in the X direction in the hollow portion 23j of the second movable portion 23, the pusher 32 tries to protrude from the side surface of the main body portion 31, as shown in FIG. It comes into stronger contact with the sliding surface 23d. Thereby, the frictional force with respect to the sliding surface 23d of the pusher 32 increases. Therefore, the moving speed of the braking member 30 forward in the X direction is suppressed, and the closing speed of the door 12 is also suppressed.
In this case, the frictional force with respect to the sliding surface 23 d of the pusher 32 is constant due to the taper shape (tilt angle) of the pusher 32 and the tension of the second compression coil spring 34. Accordingly, the frictional force increased by the forward movement of the braking member 30 in the X direction is also constant, so the closing speed of the door 12 is also constant.
Thus, when the opening degree of the door 12 becomes 35 degrees or less when the door 12 is closed, the moving speed of the braking member 30 forward in the X direction is kept constant, so that the door closing speed becomes a constant speed. Become. Accordingly, it is possible to surely prevent a finger or the like from being caught between the door 12 and the opening 11 when the door is closed, and to prevent generation of an impact sound due to a collision with the frame of the opening 11 of the door 12. can do.

  In this case, since the door closing speed is suppressed by the frictional force between the pusher 32 of the braking member 30 and the sliding surface 23d of the second movable part 23, it is necessary to use a conventional hydraulic damper. Absent. For this reason, the hinge 10 with a damper function can be comprised by the whole in small size and low cost.

On the other hand, when the door 12 is opened from the fully closed state, it is reverse to that when the door is closed, that is, sequentially in FIGS. 9D, 9C, 9B, and 9 ( As shown in A), the door 12 is closed.
At that time, during the period from the fully closed state with the door opening degree of 0 degrees to the half-opened state with the door opening degree of 35 degrees, the pusher pin 53 is moved in a straight line of the slot 31b by the swing of the link 51 as the door 11 is opened. The portion 31c is slid, thereby moving the braking member 30 rearward in the X direction.
At this time, as shown in FIG. 8A, the pusher 32 of the braking member 30 enters the recessed portion 31d, and does not protrude from the side surface of the braking member 30. Accordingly, the braking member 30 moves smoothly because the sliding surface 23d of the pusher 32 has no frictional force. Thereby, the door 12 is smoothly opened without suppressing the closing speed.

Next, the position adjustment at the time of attachment to the opening part 11 of the hinge with a damper function is demonstrated.
First, the position adjustment in the Y direction is performed by rotating the first adjustment screw 26.
Since both ends of the first adjustment screw 26 are rotatably fixed to the attachment portion 21, when the first adjustment screw 26 is rotated, the female screw portion 22c into which the first adjustment screw 26 is screwed is formed in the Y direction. The first movable portion 22 is moved and adjusted in the Y direction. As a result, as shown in FIGS. 10 and 11, the second movable portion 23, the frame 24, and the braking member 30 attached to the first movable portion 22 are also moved and adjusted in the Y direction by the distance dy. In this case, the movement adjustment in the Y direction is intuitively performed by rotating the first adjustment screw 26 extending in the Y direction.

Next, the position adjustment in the X direction is performed by rotating the third adjustment screw 28.
That is, since the third adjustment screw 28 is screwed into the screw hole 24h of the frame 24, when the third adjustment screw 28 is screwed in, the tip of the third adjustment screw 28 moves forward in the X direction. Then, the rear wall of the second movable part 23 is pushed. Here, since the second movable portion 23 is actually fixed with respect to the X direction, the frame 24 relatively moves by a distance dx rearward in the X direction. At this time, the shaft 24f of the frame 24 moves in the X direction in the through hole 23i of the second movable portion 23, and the second adjustment screw 27 moves in the X direction in the engagement hole 24b.
Thereby, the movement adjustment in the X direction is intuitively performed by rotating the third adjustment screw 28 extending in the X direction.

Finally, the position adjustment in the Z direction is performed by rotating the second adjustment screw 27.
That is, the head of the second adjustment screw 27 engages with the engagement hole 24b of the upper surface 24a of the frame 24 and is screwed into the female screw portion 23e of the second movable portion 23. When the adjustment screw 27 is loosened, the second adjustment screw 27 moves up in the female screw portion 23e and moves upward in the vicinity of the engagement hole 24b of the frame 24.
Here, since the front portion of the frame 24 is pivotally supported by the shaft 24f, the frame 24 swings about the shaft 24f, and a portion in front of the X direction from the shaft 24f swings downward in the Z direction. . As a result, the shaft 52a attached to the front end in the X direction of the frame 24 is moved and adjusted downward in the Z direction by a distance dz.
Accordingly, the movement adjustment in the Z direction is intuitively performed by rotating the second adjustment screw 27 extending in the Z direction.

The present invention can be implemented in various forms without departing from the spirit of the present invention.
For example, in the above-described embodiment, the base portion 20 has two movable portions, that is, the first movable portion 22 and the second movable portion 23, and the second movable portion 23 is the first movable portion. Although it is configured to be detachable with respect to the portion 22, these movable portions 22, 23 may be configured integrally.

  As described above, according to the present invention, it is possible to provide a hinge with a very excellent damper function that can be configured in a small size with a simple configuration and can be easily and intuitively adjusted in position. .
