Abstract

PURPOSE:To achieve miniaturization and to prevent a sliding door from bouncing back and catching fingers by causing the sliding door to follow the reacting movement of a sensor member upon detection of the different level of the recess of a guide rail during movement of the sliding door, and decelerating a main sash roller while the sliding door abuts the main sash roller. CONSTITUTION:When a main sash roller 7 passes an area near a vertical frame, a roller 39 slides on the snapping member of a guide rail 3 and an adapter 20 is rotated clockwise against energizing force. As a result, a rotary damper 34 opens or closes a sliding door with a slight force while avoiding engagement with the gear 38 of the main sash roller 7. When the main sash roller 7 enters the area near the vertical frame, the roller 39 responds to the recessed wheel of the V-rail 26 of the guide rail 3 and the adapter 20 is rotated counterclockwise as it is energized by a spring 40. Then the gear 38 of the outer member 37 of the damper 34 is engaged with the gear 32 of the main sash roller 7 and the outer member 37 gradually suppresses the force of the gear 38 under the damper action of an inner member 36 to brake the gear 32. Therefore, when closed to some extent the sliding door can be gradually decelerated just before abutting the vertical frame.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door with a speed reducer capable of sufficiently reducing the speed of the sliding door and effectively preventing the sliding door from bouncing, pinching fingers, etc., while having a relatively simple structure and being downsized.

[0002]

2. Description of the Related Art In a detached house, an office building or the like, a sliding door may be provided for partitioning an interior room. As such a sliding door, there are a hanging type and a lower supporting type, but in recent years, a large one is used.
The weight of the sliding door itself is heavy due to the fact that glass and the like are fitted into the sliding door. Therefore, a rail made of resin or the like is provided on the upper frame or the lower frame of the sliding door, and a door roller traveling on the rail is provided on the upper side or the lower side of the sliding door, whereby the opening / closing force of the sliding door is reduced as much as possible. For example, when opening and closing, a force of about 0.1 to 0.2 kg has appeared as a force applied to the sliding door, and opening and closing of the sliding door can be performed very smoothly by applying a slight force to the sliding door. ing.

[0003]

Reducing the opening / closing force of the sliding door in this way is preferable because it reduces the burden on the resident or the like who opens and closes the sliding door. However, if this opening / closing force is reduced, the sliding door moves at a relatively high speed, so even when the sliding door is closed with a light force, the sliding door bounces off the vertical frame, and carelessly, the sliding door and the vertical For example, a finger may be caught between the frames, which causes a new problem due to the reduction of the opening / closing force.

In order to prevent such bouncing, finger pinching, etc., conventionally, for example, a top hanging type sliding door is provided with a rack on the upper frame, while a gear is provided on the upper side of the sliding door so as to mesh with the rack. At the same time, the gear is configured to be gradually rotated by a hydraulic cylinder. As a result, when the sliding door is closed to some extent, the gear is gradually rotated while meshing with the rack, and as a result,
The sliding door is gradually decelerated immediately before it comes into contact with the vertical frame, the opening / closing force is increased, and the sliding door is prevented from bouncing and the fingers are pinched.

However, in such a mechanism, since a piston type hydraulic cylinder is used, the speed reducing mechanism becomes large. as a result,
For example, a relatively thin sliding door cannot be provided with such a speed reducer, and a lower-supporting type sliding door has a limited space for incorporating the speed reducer. It is difficult to incorporate the speed reducer.

The object of the present invention was made in view of the above-mentioned circumstances, and it is possible to sufficiently decelerate the sliding door and bounce the sliding door while reducing the size with a relatively simple structure.
An object of the present invention is to provide a sliding door with a reduction gear that can effectively prevent finger pinching and the like.

[0007]

In order to achieve this object, a sliding door with a reduction gear according to the present invention is a sliding door having a reduction gear housed in a housing and rotatably supported by the housing. A main door wheel, a guide rail for guiding the main door wheel, a guide rail having a concave or convex step in the vertical frame vicinity section at a position at a predetermined distance from the vertical frame, and a concave rail when the sliding door is moved to the vertical frame vicinity section. Alternatively, a detection member that detects a convex step and moves in response to it, and a speed reduction member that decelerates the main door wheel while contacting the main door wheel following the response movement of the detection member, are provided. I am trying.

[0008]

With this configuration, in the present invention, when the sliding door is moved on the guide rail and moved to a section near the vertical frame at a position at a predetermined distance from the vertical frame, the detection member is moved to this section. It moves in response to a concave or convex step. As a result, the deceleration member comes into contact with the main door wheel to decelerate the main door wheel. Therefore, when the sliding door is closed to some extent, the sliding door is gradually decelerated immediately before it comes into contact with the vertical frame, the opening / closing force is increased, and the sliding door can be prevented from rebounding and finger pinching.

Therefore, without using a large member such as a piston type hydraulic cylinder as in the conventional case,
The constituent members are integrally incorporated in the housing, and while the structure is simple and lightweight, the sliding door can be decelerated sufficiently when necessary to effectively increase the opening / closing force.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A sliding door with a speed reducer according to an embodiment of the present invention will be described below with reference to the drawings.

1 to 12, the first aspect of the present invention
An example will be described. First, roughly explaining, as shown in FIG. 1, the speed reducer-equipped sliding door according to the present embodiment is a type of a lower support in a room, and is used for a frame structure including a vertical frame 1, a lower frame 2, and the like. It is a sliding door.
However, the present invention is not limited to indoor sliding doors,
It may be used outdoors, or may be used as a single door instead of a sliding door.

The lower frame 2 is provided with a guide rail 3 made of resin. The shape and the like of the guide rail 3 will be described later, but as shown in FIG. The range d located at is a section in the vicinity of the vertical frame, and is provided with a concave step 4 as compared with other portions of the guide rail 3.

The sliding door includes a door roller device 5 having a speed reducer,
And a normal door roller device 6 are provided, and these main door rollers 7,
8 is configured to be guided on the guide rail 3.

Next, the configuration of the door roller device 5 and the guide rail 3 will be described in detail with reference to FIGS. 6 to 2 based on FIG.

As shown in FIG. 2, the door roller device 5 is provided with a housing 11 which is attached to a sliding door. The housing 11 is for adjusting the height of the sliding door as shown in FIG. Guide grooves 12 and 13 are formed.

A slide core 14 is movably accommodated in the housing 11, as shown in FIG.
As shown in FIG. 7, guide grooves 15 and 16 for adjusting the height of the sliding door are formed in the slide core 14 at an angle of approximately 45 °.
The screw hole 1 in which the screw 17 provided in the housing 11 is screwed into the side wall of the slide core 14 in order to move the screw hole 1.
8 is formed.

Further, as shown in FIG. 8, an adapter 20 is rotatably provided in the slide core 14. The adapter 20 is rotatably supported with respect to the slide core 14 by a pivot 21 fitted in a hole 19 formed in the adapter 20. Further, a pair of flanges 22 are formed below the adapter 20, and rollers 39 to be described later are provided in holes 23 of these flanges 22.
(Detection member) is rotatably attached. A hole 24 is formed above the adapter 20, and in this hole 24,
A rotary damper 34 (deceleration member) described later is attached. Further, a bent projecting piece 25 is formed on the upper right side (FIGS. 2 and 8) of the adapter 20.

As shown in FIG. 2, the adapter 20 has a spring 40 interposed between the projecting piece 41 of the slide core 14 and the projecting piece 25 of the adapter 20 so that the adapter 20 rotates counterclockwise around the pivot 21. Is always energized.

On the other hand, the guide rail 4 is shown in FIGS. 9 (a) and 9 (b).
As also shown, the V-shaped rail 26 and the V-shaped rail 2
6 and a snap member 27 fitted together, both of which are made of resin. A concave portion 28 into which the snap member 27 is fitted is formed in the center of the V-shaped rail 26, and inclined surfaces 29 on both sides of the concave portion 28 are slanted for sliding the main door pulley 7. Are formed. Engaging portions 30 for attaching to the lower frame 3 are provided on both outer sides of the V-shaped rail 26.
Are formed. Further, the top surface of the snap member 27 is formed smooth, and a recess 31 is formed below the snap member 27 so as to be bent at the time of fitting.

In this embodiment, this snap member 27 is not fitted to the V-shaped rail 26 in the section d near the vertical frame shown in FIG. 1, so that the concave step 4 is formed.
A snap member 27 is fitted in a portion other than the vertical frame vicinity section d. Further, as shown in FIG. 1, the changing portion between the vertical frame vicinity section d and the other portions is configured to be appropriately inclined. Depending on the configuration of the roller 39 (detection member), the vertical frame vicinity section d may be formed in a convex shape, and the other portions may be formed in a concave shape.

Next, as shown in FIGS. 10 (a) and 10 (b), the main door pulley 7 is made of resin, and the gear 3 of the rotary damper 34 (deceleration member) is provided at the center of the outer peripheral surface thereof.
It has a gear 32 that meshes with the gear 8. This gear 32
The main door pulley 7 is configured to slide on the snap member 27 when passing through a section other than the vertical frame vicinity section d. Further, inclined surfaces 33 are formed on both sides of the gear 32. The inclined surface 33 is configured to slide on the inclined surface 29 of the V-shaped rail 26 of the guide rail 4 when the main pulley 7 passes through the vertical frame vicinity section d.

Further, the rotary damper 34 (deceleration member) mounted above the adapter 20 is a fixed shaft 3
5 and an annular outer member 37 provided so as to rotate around the outer periphery thereof. A gear 38 that meshes with the gear 32 of the main door wheel 7 is formed on the outer peripheral surface of the annular outer member 37. On the other hand, the fixed shaft 35 of the inner member 36 is non-rotatably fixed to the adapter 20, so that the inside of the fixed inner member 36 is not particularly illustrated, but when the outer member 37 rotates. , The rotation of the outer member 37 is gradually allowed. That is, silicon oil is contained inside the inner member, and when the outer member 37 is rotated, this oil is made to flow through the orifice while being pressurized. Thereby, when a force is applied to the outer member 37 from the gear 32 of the main door wheel 7 to rotate the outer member 37, the outer member 37 is
The force is gradually rotated while suppressing this force, and as a result, the rotation of the gear 32 is braked.

In this embodiment, the rotary damper 34 (reduction member) is integrally constructed so as to have both the function of engaging with the gear 32 of the main door wheel 7 and the function of the damper for deceleration. Alternatively, the gear that meshes with the gear 32 of the main door wheel 7 and the damper may be separately configured and arranged coaxially.

Further, the roller 39 (detection member) rotatably mounted in the hole 23 of the flange 22 of the adapter 20 is made of resin as shown in FIGS. When the door roller 7 passes through a section other than the vertical frame vicinity section d, the door roller 7 is configured to slide on the snap member 27 against the biasing force of the spring 40.
Is passing through the vertical frame vicinity section d, the spring 40
It is configured to slide on the recessed portion 28 (concave step 4) of the V-shaped rail 26 of the guide rail 3 by the biasing force of.

Next, the operation of the sliding door with the speed reducer according to this embodiment will be described. When the main door carriage 7 of the sliding door passes through a section other than the vertical frame vicinity section d, the state is as shown in FIG. That is, the roller 39 slides on the snap member of the guide rail 3, and at this time, the pressing force from the roller 39 overcomes the biasing force of the spring 40, so the adapter 20 resists this biasing force. It is rotated clockwise. As a result, the rotary damper 34 is not meshed with the gear 38 of the main door wheel 7. Therefore, the sliding door is opened and closed by a very light force.

On the other hand, when the main door wheel 7 of the sliding door enters the section d near the vertical frame, the state shown in FIG. 3 is obtained. That is,
When the main door wheel 7 of the sliding door enters the vertical frame vicinity section d, the roller 39 (detection member) causes the V-shaped rail 26 of the guide rail 3 to move.
In response to the concave portion 28 (concave step 4), the adapter 20 supporting the roller 39 is rotated counterclockwise by the urging force of the spring 40. As a result, the outer member 37 of the rotary damper 34 (deceleration member) is
Gear 38 of the main door wheel 7 is meshed with the gear 32 of the main door wheel 7, and the outer member 37 of the damper 34 is gradually rotated by the damper action of the inner member 37 described above, thereby gradually suppressing the force of the gear 38. As a result, the rotation of the gear 32 is braked. As a result, when the sliding door is closed to some extent,
Immediately before contacting the
Bounce of the sliding door and pinching of fingers can be prevented. Therefore,
Unlike the prior art, without using a large member such as a piston type hydraulic cylinder, a (deceleration member) component such as a rotary damper 34 is integrally incorporated in the housing 11, and the configuration is simple and lightweight. When necessary, the sliding door can be decelerated sufficiently to effectively increase the opening / closing force.

In the present embodiment, the main door pulley is decelerated by meshing the gears in this way, but the friction wheel is rubbed against the main door roller or the like which does not have a normal gear. Therefore, the main door may be decelerated.

Next, the adjustment of the height of the sliding door will be described. 2 and 3 show a state in which the sliding door is in the highest position, and FIGS. 4 and 5 show a state in which the sliding door is in the lowest position. The adjustment of such a sliding door will be described by comparing FIGS. 2 and 4.

When the sliding door is adjusted from the highest position to the lowest position, the screw 17 is rotated in the tightening direction in FIG. As a result, the entire slide core 14 in which the screw hole 18 into which the screw 17 is screwed is formed is
It is moved to the right in FIGS. 2 and 4. At this time, the guide grooves 12, 1 of the housing 11 fixed to the sliding door
3 is immovable laterally. Therefore, the shaft of the main door roller 7 and the pivot 21 of the adapter 20 apparently move upward in the guide grooves 12 and 13, and move obliquely upward along the oblique guide grooves 15 and 16 in the slide core 14. To be done. Thus, the shaft of the main door wheel 7 and the adapter 20
As a result of the pivot shaft 21 of the above is moved obliquely upward with respect to the slide core 14, the sliding door is moved downward by the height of this movement. On the other hand, when the sliding door is moved from the lowest position to the highest position, the screw 17 may be rotated in the opposite direction. However, FIG. 4 shows a state where the sliding door is at the lowest position and the reduction gear is not operating.
Shows the state in which the speed reducer is operating with the sliding door being in the lowest position.

Next, a sliding door with a reduction gear device according to a second embodiment of the present invention will be described with reference to FIGS. 13 and 14. However, the same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted and the description of the height adjustment of the sliding door will be omitted.

As shown in FIG. 13, in this embodiment, the main door pulley 5 provided on the slide core 14 in the housing 11 is provided.
No gear is formed on the outer peripheral surface of the main door pulley 51.
The outer peripheral surface is formed to be convex toward the center.
Further, the adapter 20 is configured to be rotatable about the pivot 21 as in the first embodiment, and the spring 40
The roller 39 (detection member) is provided below the adapter 20 while being urged in the counterclockwise direction by.

On the other hand, similarly to the first embodiment, the guide rail 3 also has a snap member 27 which is not fitted to the V-shaped rail 26 in the vertical frame vicinity section d as shown in FIG. As shown in FIG. 13, the snap members 27 are fitted to the V-shaped rails 26 at locations other than the frame vicinity section d.

In this embodiment, instead of the rotary damper 34 (deceleration member) of the first embodiment, as shown in FIG. 13, an arc-shaped brake for frictionally decelerating while contacting the outer peripheral surface of the main door wheel 51. A shoe 53 is provided. The brake shoe 53 is made of resin or the like in three layers, and its cross-sectional shape is formed to be concave toward the center corresponding to the cross-sectional shape of the main door wheel 51 whose outer peripheral surface is convex toward the center. ing. The brake shoe 53 is attached to the adapter 20 by the support member 52, and the center line of the arc of the brake shoe 53 is the main door wheel 51.
It is arranged to face the axis of.

With this construction, in this embodiment, when the main door wheel 51 of the sliding door enters the vertical frame vicinity section d, the state shown in FIG. 14 is obtained. That is, when the main door wheel 51 of the sliding door enters the vertical frame vicinity section d, the roller 3
9 (detection member) responds to the concave step 4 of the V-shaped rail 26 of the guide rail 3, and as a result, the adapter 20 supporting this roller 39 is rotated counterclockwise by the urging force of the spring 40. It As a result, the brake shoe 53 (deceleration member) makes frictional contact with the outer peripheral surface of the main door wheel 7, and gradually suppresses the turning force of the main door wheel 51 to brake the main door wheel 51. As a result, when the sliding door is closed to some extent, the sliding door is gradually decelerated immediately before it comes into contact with the vertical frame 1, the opening / closing force is increased, and the sliding door can be prevented from rebounding, finger pinching and the like. Therefore, without using a large member such as a piston-type hydraulic cylinder, the sliding door can be decelerated sufficiently when necessary, and the opening / closing force can be effectively increased while the structure is simple and lightweight.

The present invention is, of course, not limited to the above-mentioned embodiments, but can be variously modified. In particular, matters that can be modified in the specification are included in the scope of the present invention.

[0036]

As described above, according to the present invention, when the sliding door is moved on the guide rail and moved to the vertical frame vicinity section at the position of the predetermined distance from the vertical frame, the action of the detection member causes
The deceleration member comes into contact with the main door wheel to decelerate the main door wheel. Therefore, when the sliding door is closed to some extent, the sliding door is gradually decelerated immediately before it comes into contact with the vertical frame, the opening / closing force is increased, and the sliding door can be prevented from rebounding and finger pinching. Therefore, unlike the conventional technology, the components are integrated into the housing without using a large member such as a piston type hydraulic cylinder, and the structure is simple and lightweight, but the sliding door is decelerated sufficiently when necessary. The opening / closing force can be effectively increased.
