Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a soft closer mechanism that completes a gentle operation from the vicinity of the end of movement of a moving body toward the end of movement.
[0002]
[Prior art]
Conventionally, a soft closing mechanism is applied to a movable part such as a drawer or a door to perform a gentle closing operation. For example, as disclosed in Patent Document 1, “for closing operation and / or pulling in a movable part of furniture” Is known. FIG. 7 is a perspective view of the soft closer mechanism disclosed in the patent document.
[0003]
In FIG. 7, 01 is a closer, which is a rotary damper having a slider 03 supported by a closer plate 02 that can move in the same direction as a movable member (not shown) and a pinion 04 that meshes with a rack 03a of the slider 03 (see FIG. 7). And a closer hook 06 which is swingably attached to the slider 03 via a shaft 05. The slider 03 is always pulled in the closing direction of the door by a tension spring 07 having one end locked to the closer plate 02 and the other end locked to the closer hook 06, but the movable member acts. In a state where the movement is not performed, the slider 03 is not moved in the closing direction of the door because the movement is restricted by the guide way 08 to which the closer hook 06 is offset.
[0004]
The soft closer mechanism includes a closer 01 and a pin (not shown) attached to the movable member, and the closer hook 06 has an arcuate hole 06a that can be engaged with the pin of the movable member. When the movable member moves in the closing direction and the pin catches the arc-shaped hole 06a, the closer hook 06 swings away from the offset guide way 08, and the slider 03 is integrated with the movable member in the closing direction. Moving. At this time, since the slider 03 rotates the pinion 04 engaged with the rack 03a, the slider 03 is decelerated by a buffering action from the rotary damper.

[0011]
In the soft closer mechanism of the present invention, it is preferable that the elastic member is a spring member housed in a groove extending in parallel with the moving direction of the moving body formed on the surface of the slider.
In this way, by storing the spring member in the groove, the closer can be made compact, and the groove extends in parallel with the moving direction of the moving body, so that the slider can be moved smoothly.
[0012]
In the soft closer mechanism according to the present invention, the guide portions are formed on the left and right sides of the slider, and two pairs of grooves are formed on the front and back surfaces of the slider from the middle position between the guide portions to the target position. It is preferable.
In this way, since the spring members can be freely selected and stored in the four grooves, the number of spring members can be increased or decreased based on the weight of the moving body, and the spring members can be displayed on the slider. By disposing the slider on the back surface, it is possible to prevent the slider from being lifted, and by disposing two on the front or back surface of the slider, the slider can move smoothly without twisting in the horizontal direction of the slider.
[0013]
In the soft closer mechanism of the present invention, it is preferable that the closer housing is constituted by connecting two detachable casings for accommodating closer parts including a slider, a damper, and a closer hook.
In this way, the closer part can be protected, and at the same time, the closer part can be easily replaced or inspected.
[0014]
In the soft closer mechanism of the present invention, the moving body is a door, the fixed body is a cabinet body having an opening, the moving end direction of the moving body is a direction to close the door, and the counter moving end direction is to open the door. It is preferable that the direction is.

[0019]
Thus, by arranging the mounting height position of the soft closer mechanism at substantially the same level as the mounting position of the handles H1 and H2 in the vicinity of the central portion in the height direction of the hanging door 1, both the outer doors 1b and 1c are arranged. Can be opened and closed stably without distortion.
[0020]
Next, the soft closer mechanism of the present invention will be described with reference to FIGS.
[0021]
The soft closer mechanism is intended to complete a gradual closing operation from the vicinity of the closing operation end of the hanging door 1 toward the closing operation of the door, and the rear surfaces of the outer doors 1b and 1c of the hanging door 1. The locking pin 10 provided on the horizontal support piece 6c of the bracket 6 (see FIG. 4) attached to the left and right ends of the door, and the locking pin 10 near the end of the closing operation of the outer doors 1b and 1c. It consists of closers S1 and S2 with different right and left sides attached to the lower surface of the left and right ends of the shelf 2a to be engaged and disengaged, and the locking pin 10 is rotatably fitted to the metal pin shaft 10a and the pin shaft 10a. And a buffer tube 10b made of a soft material such as synthetic resin.
[0022]
These closers S1 and S2 are housed inside a case body with a different right and left shape formed in a thin rectangular shape, which will be described later, which can be divided into upper and lower sides. As shown in FIG. A base casing S2a that is a closer housing integrally formed of a resin material, and a cover casing S2b that is joined to the joint portion of the base casing S2a are joined to each other. The base casing S2a has left and right ends of the front end of the shelf 2a. It is directly attached to the back of the unit.
[0023]
3 (a) and 3 (b) show a right-handed closer S2, which includes a slider 12 supported by a case body so as to be movable in the opening / closing direction of the suspension door 1, and the slider S2. 12 is composed of a rotary damper 14 that decelerates the movement of the outer door 1c in the closing direction, and a closer hook 16 that is attached to a part of the slider 12 in front.
[0024]
On the bottom surfaces of the base casing S2a and the cover casing S2b facing each other, guide rails 18a ′, 18b ′ and 18a, 18b which are parallel to the moving direction of the doors, which are two guide portions spaced apart by a predetermined distance to guide the slider 12, are provided. Projecting over the entire length in the longitudinal direction, a gap for inserting the closer hook 16 is formed between the joints facing the front end edges of both casings S2a and S2b. A notch groove 20 having a predetermined length is formed along the longitudinal direction.
[0025]
Further, a straight groove 22a having a predetermined length is formed on the opposing surfaces in front of the base casing S2a and the cover casing S2b from the vicinity of one end along the inside of the notch groove 20, and the outside of the straight groove 22a. An arc groove 22b having a predetermined radius is formed continuously with the door opening direction end portion bent inward at a right angle.
[0026]
A housing area for disposing a known rotary damper 14 is provided in the rear of the case body. The outer periphery of the mounting flange 14a of the rotary damper 14 is inserted into the bottom surface of the cover casing S2b serving as the housing area. A receiving recess 25 having a predetermined depth to be fitted is formed, and a support piece 15 is provided on the bottom surface of the base casing S2a so as to project and support the front end of the rotary damper 14 at a position opposed to the receiving recess 25. Yes.
[0027]
The rotary damper 14 is a rotary damper that uses a braking force generated by the viscous resistance of oil sealed inside, and is limited in one rotational direction of the output shaft 14b to which the pinion gear P is mounted. It has a structure in which power is applied and free rotation without braking load is obtained in the other rotation direction.
[0028]
Then, the guide rails 18a ', 18b' and 18a, 18b of the opposing casings S2a, S2b are formed in a flange shape at one end of a tension coil spring SP that becomes a pair of upper and lower elastic members, which will be described later. A pair of vertically long locking grooves G1 for locking the formed locking portions SP1 are formed at opposing positions.
[0029]
Guide rails 18a ', 18b' and 18a, 18b formed on the bottom surfaces of the casings S2a, S2b facing each other fit into a pair of guide grooves on the upper and lower surfaces of the resin slider 12 formed in a rectangular plate shape, The slider 12 guides and supports the movement of the door in the opening and closing direction.
[0030]
The slider 12 is formed with an outer rectangular engagement cylinder portion 26 in which an engagement recess for inserting an end portion of a locking arm 28 of a closer hook 16 to be described later is formed in front of the outer door closing direction end portion side. At the same time, rack teeth R are formed on the rear side surface along the longitudinal direction.
[0031]
Furthermore, block portions BL1 and BL2 having a predetermined thickness project from end portions of the upper and lower surfaces of the slider 12 in the opening direction of the outer doors 1b and 1c, and the block portions BL1 and BL2 have one end in the vertically long locking groove G1. A pair of locking grooves G2 for locking the flange-shaped locking portions SP2 (see FIGS. 3 to 5) at the other ends of the pair of upper and lower tension coil springs SP locked with the upper and lower surfaces are respectively formed on the upper and lower surfaces. .
[0032]
Rail pieces 34a and 34b formed on the front upper and lower surfaces extend along the longitudinal direction at the front ends of the block portions BL1 and BL2 protruding from one end of the upper and lower surfaces of the slider 12, and these rail pieces 34a. , 34b, one guide rail 18b, 18b 'is inserted between the locking piece K formed adjacent to one end side of the engaging tube portion 26 and the rear end of the engaging tube portion 26 on the other end side. . A sliding surface 19 is formed on the rear end side surface of the block portions BL1 and BL2 so as to contact the inside of the other guide rails 18a and 18a ′ and guide the slider 12 in the opening and closing direction.
[0033]
In addition, a pair of coil springs on the upper and lower surfaces of the equal positions Y1, Y2 of the slider 12 as the target position with respect to the center line Y (see FIG. 6) which is the intermediate position in the width direction of the guide rails 18a, 18b and 18a ′, 18b ′. Shallow grooves 12a and 12b having a circular arc cross section for accommodating the SP are formed in parallel with the moving direction (opening / closing direction) of the door.
[0034]
Therefore, the engaging portions SP2 and SP1 at both ends of the pair of upper and lower tension coil springs SP are engaged with the pair of upper and lower engaging grooves G2 of the slider 12 and the pair of upper and lower engaging grooves G1 facing the casings S2a and S2b. The slider 12 is urged in the door closing direction, and one side surface of the engaging cylinder portion 26 is provided at the end of the outer door closing direction inside the casings S2a and S2b. Even in this state, the rack teeth R of the slider 12 mesh with the pinion gear P of the rotary damper 14 accommodated in the accommodation recess 25.
[0035]
It is not necessary to stretch the coil springs SP in all of the shallow grooves 12a, 12b having a circular arc cross section that accommodates the four coil springs SP formed on the slider 12, and the necessary number of springs are provided in consideration of the weight of the door to be used. What is necessary is just to arrange | position. In addition, when four or more springs are provided, the casing and slider are designed to increase the number of locking grooves and shallow grooves accordingly. However, when at least two springs are used, preferably an even number is used. These springs may be evenly arranged vertically or horizontally so that there is no distortion in the vertical and horizontal directions of the slider.
[0036]
On the other hand, the engagement recess formed in the engagement cylinder portion 26 of the slider 12 has a cross-shaped concave groove 28a, 28b (only a pair of concave grooves are shown in FIG. 3b) in a direction perpendicular to the moving direction of the slider 12. Engagement projections T1 and T2 projecting on both sides of the end of the locking arm 28 of the closer hook 16 inserted into the concave grooves 28a and 28b from the opening end are supported slidably, In this state, the engaging protrusions 30a, 30b and 30a ', 30b' projecting from the left and right sides of the front side upper and lower surfaces of the closer hook 16 are slidably guided and supported by the linear grooves 22a or the arc grooves 22b. Yes.
[0037]
The notch hole F formed as a hook portion at the tip of the closer hook 16 is formed with an arc portion 16a in the middle and with a predetermined angle on both sides thereof, as shown in FIGS. The first straight portion 16b and the second straight portion 16c, and the third straight portion 16d connected to the second straight portion 16c.
[0038]
Therefore, when the closer hook 16 is on the outer door 1b, 1c closed end side of the linear groove 22a or the outer door 1b, 1c open side which is the end of the arc groove 22b, the closer hook 16 is shown in FIG. As shown in FIG. 2, two different modes to be described later are taken.
[0039]
Next, the operation of the soft closer mechanism will be described.
[0040]
First, when the outer doors 1b and 1c shown in FIG. 1 are in the closed position, the closer hook 16 configured as described above has a locking pin 10 formed with a notch hole F as shown in FIG. Is held on the closed end side (right end side).
[0041]
Therefore, either or both of the outer doors 1b and 1c are opened from the closed state with the handle H1 or H2. For example, when the outer door 1c is opened, the guide pin 8 moves in the guide groove 5a of the rail 5 by the movement of the outer door 1c, and the locking pin 10 that moves integrally with the guide pin 8 is shown in FIG. As shown, the slider 12 moves to the left (opening direction) against the urging force of the pair of upper and lower tension coil springs SP in the state of being engaged with the notch hole F of the closer hook 16.
[0042]
When the slider 12 moves to the left, the rotary damper 14 freely rotates clockwise through the pinion gear P meshed with the rack teeth R of the slider 12.
[0043]
When the closer hook 16 further moves left together with the slider 12 with the locking pin 10 locked, the closer hook 16 has its engaging projections 30a, 30b and 30a ', 30b' changed from the linear groove 22a to the arc groove 22b. When shifting, the engaging projections T1 and T2 integrated with the front and back of the end of the locking arm 28 engaged in the concave grooves 28a and 28b of the engaging cylinder portion 26 move forward in the opening side. It swings clockwise around the mating protrusions T1, T2.
[0044]
Further, the notch hole portion F of the closer hook 16 is positioned so that the third straight portion 16d is collinear with the front edge of the case body as indicated by the phantom line in FIG. It becomes an inclined posture.
[0045]
As a result, the locking pin 10 inside the outer door 1c is easily pulled out from the cutout hole F of the closer hook 16, and the outer door 1c becomes movable to the open end. At this time, while the buffer tube 10b that is rotatably fitted to the pin shaft 10a is in contact with the second linear portion 16c, it is rotated by the frictional force thereof.
[0046]
The engagement protrusion 30a (30a ') of the closer hook 16 after the locking pin 10 is pulled out engages with the end groove of the arc groove 22b, and the urging force of the tension coil spring SP is two points in FIG. Since the closer hook 16 indicated by the chain line is further swung clockwise, the slider 12 is locked in this position and this posture is maintained.
[0047]
Next, when closing the opened outer door 1c, the locking pin 10 that moves to the right integrally with the guide pin 8 of the outer door 1c is provided on the closer hook 16 positioned on the outer door opening side. Engage with the tip notch hole F.
[0048]
Specifically, as shown in FIG. 3A, when the locking pin 10 abuts on the second straight portion 16b of the closer hook 16, the closer projection T1, T2 is formed in the concave grooves 28a, 28b. The engagement protrusions 30a, 30b and 30a ′, 30b ′ are guided by the arc groove 22b and swing counterclockwise around the engagement protrusions T1, T2 while moving rearward along the opening side.
[0049]
Therefore, while the closer hook 16 swings counterclockwise, the buffer tube 10b that is rotatably fitted to the pin shaft 10a rotates while contacting the first linear portion 16b.
[0050]
The slider 12 moves to the right via the closer hook 16 due to the movement of the locking pin 10 jumping into the circular arc portion 16a of the cutout hole F in the closing direction of the outer door, and at the same time the rack of the slider 12 is racked. When the rotary damper 14 rotates counterclockwise via the pinion gear P meshing with the tooth R, a braking force is generated in the rotary damper 14.
[0051]
Therefore, when the inertial force of the outer door 1c moving in the closing direction is large, the impact is mitigated by moving to the closing end while the speed is rapidly decelerated, and when the inertial force of the outer door 1c is small, The slider 12 can be automatically and gently moved to the closed end by the pulling force of the tension coil spring SP, and the impact force is alleviated by the last contact of the one side surface of the engagement tube portion 26 with the buffer contact portion 32. And stop.
[0052]
Therefore, according to the soft closer mechanism configured as described above, since the tension coil spring SP can be directly stretched on the slider 12, the attachment position and the number of degrees of freedom of the tension coil spring SP are widened. It is also possible to apply an elastic force in the same direction as the moving direction.
[0053]
Further, the rail pieces 34a and 34b of the slider 12 and the sliding surface 19 are in sliding contact with the guide rails 18a and 18b and 18a 'and 18b' formed on the base and cover casings S1a (S2a) and S1b (S2b). Since the guide portion is configured, the slider 12 can be moved stably.
[0054]
Further, since the tension coil springs SP are housed in the shallow grooves 12a and 12b having arc-shaped cross sections extending in the opening and closing direction of the suspension door 1 formed on the front and back surfaces of the slider 12, the closers S1 and S2 are compact. Moreover, since the shallow grooves 12a and 12b extend in the opening / closing direction of the suspension door 1, an elastic force can be applied in the same direction as the moving direction of the slider 12.
[0055]
Since two pairs of shallow grooves 12a and 12b are formed at the target position (Y1, Y2) from the center line Y which is an intermediate position in the width direction of the guide rails 18a, 18b and 18a ′, 18b ′, It is possible to increase or decrease the number of tension coil springs SP based on the weight of the suspension door 1 that can freely select and store the tension coil springs SP in the shallow grooves 12a and 12b. Further, by arranging the tension coil springs SP on the front and back surfaces of the slider 12, it is possible to prevent the slider 12 from being lifted, and by arranging them two evenly on the front or back surface of the slider 12, the horizontal direction of the slider 12 can be prevented. Therefore, the slider 12 can be moved smoothly.
[0056]
Further, the base casings S1a and S2a are attached to the cover casings S1b and S2b in a detachable connection, and are configured as a box body that houses a closer part including the slider 12, the damper 14, and the closer hook 16. In addition to protecting the closer part, the box body can be attached to the cabinet body 2 at the same time. In addition, since the two casings are detachable, the closer parts can be easily replaced and disassembled for inspection.
[0057]
In the above embodiment, the soft closer mechanism is applied to the suspension door 1 having a configuration in which each outer door can move independently. However, this mechanism is applied to a plurality of synchro slide doors (not shown). In this way, left and right outer doors can be closed to the left and right evenly by installing soft closer mechanisms so that the left and right outer doors complete a gentle closing operation with respect to the cupboard body 2. In particular, when the tension coil spring SP is mounted, the cabinet opening can be completely closed by the outer doors.
[0058]
Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these examples. For example, the door has been described as a hanging door, but it can be applied to a normal opening / closing door. Needless to say. Also, the scope of the present invention includes a case where a soft closer mechanism is attached by fitting a door into an opening of a built-in storage portion such as a closet.
[0059]
