[0002]

2. Description of the Related Art Heretofore, there has been known a swinging sliding door in which a sliding door running on an upper and lower rail can freely swing at an end of the upper and lower rail. In this conventional swing sliding door, a main traveling tool is provided on the upper and lower rails above and below one end of the sliding door, and an auxiliary traveling tool is provided on the upper and lower rails above and below the other end of the sliding door. The depth of insertion into the upper and lower rails is shallow, and a notch is provided in the front part near the end of the upper and lower rails, so that the main traveling tool can freely travel on the upper and lower rails without jumping out of the notch, In the notch, the upper and lower rails can be freely moved in and out, and the auxiliary traveling tool is made to protrude to the outside at the notch, so that the sliding door swings around the main traveling tool portion fitted in the upper and lower rails.

[0003]

In this conventional example, there is a problem that the appearance is deteriorated because a cutout portion is provided in the upper and lower rails so that the sub-running tool projects outside. In addition, when the sliding door swings around the main traveling tool part fitted into the upper and lower rails with the auxiliary traveling tool protruding from the notch, the upper and lower main traveling tools are shifted in the horizontal direction and the sliding door tilts smoothly. There is a problem that it is difficult to swing. Further, in the case where a notch is provided on the front surface of the upper and lower rails to allow the auxiliary traveling tool to protrude, there is a problem that the structure becomes complicated when two or more upper and lower rails are provided.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide no cutouts on the front surfaces of the upper and lower rails and to tilt the sliding door. It is an object of the present invention to provide a swing sliding door which can swing smoothly and can prevent a pinion from coming off a rack in a state of swinging with a simple configuration and can reliably prevent a tilt in a swing state.

[0005]

In order to solve the above-mentioned problems, a swing sliding door of the present invention comprises a main traveling tool 4 which is mounted on upper and lower rails 2 and 3 so as to be able to travel freely above and below one end of a sliding door 1. The main traveling tool 4 is provided with a pinion 5 that is rotatable with respect to the sliding door 1. Auxiliary running tool 6 that can be pulled out freely
And a rack 7 in which the pinion 5 of the main traveling tool 4 meshes only at a part of the longitudinal direction of the upper and lower rails 2 and 3. The end of the shaft 60 of the pinion 5 is axially movable and has a spring material 61. Is provided in the upper rail 2, and when the pinion 5 and the rack 7 begin to mesh with each other, the downward projecting portion 64 for the leading end of the moving body 62 to jump over while elastically contacting the moving body 62 is provided. Provided and downward projection 6
A press contact base 66 having a shorter projecting length downward than the downward projection 64 for the distal end of the moving body 62 to elastically contact with the end of the upper rail 2 is provided between the lower projection 4 and the end of the upper rail 2. The side surface opposite to the press contact base 66 is defined as an introduction inclined surface 63a,
The side surface of the downwardly projecting portion 64 on the side of the press contact base 66 is formed as an escape inclined surface 63b. With such a configuration, when the pinion 5 starts to mesh with the entrance of the rack 7 and moves along the rack 7, the moving body 62 is moved downward by the introduction inclined surface 6 of the downward projection 64.
The lower end of the moving body 62 elastically contacts the lower surface of the press-contacting base 66 after passing through the downward projection 64 while being pushed down against the spring material 61 while using the 3a as a guide. Thus, in the swing state in which the pinion 5 meshes with the rack 7, the pinion 5 is prevented from coming off the rack 7 and the sliding door 1 is prevented from tilting.

Further, it is preferable that the press contacting base 66 is provided with a groove 65 into which the upper end of the moving body 62 enters and moves. With such a configuration, it is possible to prevent the pinion 5 from rattling in the width direction of the upper rail 2 and reliably maintain the meshing state between the pinion 5 and the rack 7 in the swing state.

Here, the upper shaft 23 is provided with an upper holding block 19a to be mounted on an upper portion of a concave portion 70 provided at one end of the sliding door 1.
The lower shaft 20 is rotatably held by a lower holding block 19b attached to one end of the sliding door 1, but is held so as not to move in the vertical direction. Further, the upper shaft 23 and the lower shaft 20 are connected by a connecting shaft, so that both are integrally rotated.

A rack 7 is provided on a side surface inside the longitudinal ends of the upper and lower rails 2 and 3. Also, upper rail 2
And two lower rails 3 are arranged side by side. As shown in FIG. 4, the two upper rails 2 arranged side by side are formed by integral molding. Rail 3
Is formed by integral molding. The upper surface between the side edges of the opening for both rails of the two lower rails 3 formed by integral molding has a mountain-like shape with a higher center, and the two halves of this mountain-shaped upper surface are respectively formed on both sides. The running surface 21 is inclined. The running surface 2 which is the upper surface on one side of the upper surfaces on both sides of each rail opening of the lower rail 3
Numeral 1 is higher than the upper surface of the other one of the upper surfaces of both side edges of each rail opening so that the horizontal wheel 10 provided on the main traveling tool 4 is mounted on the inclined traveling surface 21 and travels. It has become. In other words, only the portion of the lower surface of the horizontal wheel 10 that is in contact with the traveling surface 21 on one side is placed,
The horizontal wheel 10 can rotate smoothly with low resistance, and can run and swing more smoothly. In addition, the inclination of the inclined running surface 21 is a gentle inclination, so that it is not difficult to walk even when the running surface 21 has the mountain shape as described above during walking.

When the rack 7 is provided on the lower rail 3, the running surface 21
The rack 7 is provided along the side farthest from the rack 7. With such a configuration, a portion where the load of the sliding door 1 is supported on the lower rail 3 by the horizontal wheel 21 and a portion where the pinion 5 meshes with the rack 7 are balanced on both sides of the axis of the main traveling tool 4. As a result, the main traveling tool 4 can travel and rotate smoothly in a well-balanced manner with respect to the lower rail 3. Particularly, as shown in FIG. 4, by making the traveling surface 21 an inclined surface, when the horizontal wheel 10 is placed on the inclined traveling surface 21,
Although the lower main traveling tool 4a tends to shift in the direction of the arrow in FIG.
Since the rack 7 is arranged along the side of the lower rail 3 that is farthest from the running surface 21, the force for shifting is a force in the direction in which the pinion 5 meshes with the rack 7. Therefore, for this reason, the phenomenon that the pinion 5 moves in the direction away from the rack 7 and rattles can be prevented.

On the lower surface of the upper surface at the end of the upper rail 2, a downward projecting portion 6 is formed in the vicinity of the entrance of the rack 7.

The side surface on the side of the press contact base 66 is an escaped inclined surface 63b.

As shown in FIG. 8, a moving body 62 is fitted in a shaft portion 60 of the pinion 5 of the upper main traveling tool 4b so as to be movable up and down. I'm going. Here, the shaft portion 60 of the pinion 5
May be formed integrally with the upper shaft 23 described above, or may be formed integrally with the pinion 5, or the upper shaft 2
The shaft portion 60 separate from the pinion 3 and the pinion 5 may be attached to the pinion 5.

The moving body 62 has an upper end in elastic contact with the downward projection 64 and the pressing projection 66 at the downward projection 64 and the pressing projection 66, but the downward projection 64 and the pressing projection 66. In a portion where the base 66 is not provided, the lower surface of the upper surface of the upper rail 2 is in a non-contact state. At the other end of the sliding door 1, there is provided an auxiliary traveling tool 6 which is fitted to the upper and lower rails 2 and 3 so as to be able to travel freely and can be freely moved up and down and can be pulled out from the upper and lower rails 2 and 3. As will be described in detail later, the auxiliary traveling device 6 includes an upper auxiliary traveling device 6b and a lower auxiliary traveling device 6a.

That is, a concave portion 80 is provided on the side surface at the other end of the sliding door 1, and a support block 94a is mounted movably up and down on a guide frame 91a mounted on the lower portion of the concave portion 80. The lower shaft body 33 cannot be moved up and down, but is rotatably inserted into the lower shaft body 94a. The horizontal roller 34 is vertically moved relative to the lower shaft body 33 at a position slightly above the lower end of the lower shaft body 33. Although it is not possible, it is mounted rotatably. The lower portion of the lower shaft body 33 is a lower guide 35, and the lower guide 35 and the horizontal roller 3
4 and the lower shaft 33 constitute a lower auxiliary traveling tool 6a.

Further, a support block 94a is provided for a guide frame 91b mounted on the upper portion of the concave portion 80 at the other end of the sliding door 1.
Are mounted to be movable up and down.
The upper shaft 39 cannot be moved up and down, but is rotatably inserted and mounted on the upper shaft 39. An upper guide 40 is provided at the upper end of the upper shaft 39 to form an upper auxiliary traveling tool 6b. It is.

The upper connecting shaft 41 is provided on the upper support block 94a.
Are connected to each other, and the lower end of the lower connecting shaft 36 is connected to the lower support block 94b. As shown in FIG. 6, a central frame 99 is attached to a substantially central portion in the vertical direction in the concave portion 80 on the side surface at the other end of the sliding door 1. The central frame 99 is configured by connecting the upper and lower frame bodies 45. As shown in FIG. 6, a handle 46 is rotatably supported on each of the shaft supporting portions 45a provided on the upper and lower frames 45, respectively. Here, a portion slightly forward of the rear end of the handle 46 is supported by the shaft supporting portion 45d by a shaft 46a. The handle 46 pivotally supported by each frame 45 is in a state in which the handle 46 fits into the upper handle storage groove 45b around the shaft 46a from the state in which the handle 46 fits into the lower handle storage groove 45b. It is rotatable in the range. That is, the handle 46 is rotatable within a rotation range of about 180 ° in a vertical plane.

A moving body 47 is attached to the back of the upper and lower frames 45 so as to be movable in the vertical direction. In the embodiment shown in the accompanying drawings, the rear portion of the frame 45 and the frame 45
A moving body 47 is vertically movably disposed between the moving body 47 and a pin 54 attached to the moving body 47. The movable body 47 is provided with a bottomed cylindrical portion 47a having an open front, and a spring 4 is provided in the bottomed cylindrical portion 47a.
A pressing body 49, which has the interior 8 and is urged forward by the spring 48, is fitted so as to be movable in the front-rear direction. The front end of the pressing body 49 is supported at the rear end of the handle 46 by a shaft 46b.

When the handle 46 is rotated, the moving body 47 is moved vertically while the pressing body 46 is moved backward against the spring 48. For example, when the handle 46 is rotated in the direction of the arrow in FIG. 6 in a state where the handle 46 is housed in the upper handle housing groove 45b supported by the lower frame 45 as shown in FIG.
The moving body 47 attached to the lower frame 45 moves upward in FIG. 6 while being pushed rearward against the shaft 46a and the shaft 4a.
6b is over the so-called neutral position located on the same horizontal line, and further when the handle 46 is located in the lower handle storage groove 45b, the movement of the moving body 47 stops and the handle 46 is stored by the force of the spring 48. The moving body 47 is stopped by being pressed against the groove 45b. When the handle 46 is turned in the opposite direction, the operation returns to the state shown in FIG. 6 through the reverse operation.

A concave portion 80 provided on the side surface at the other end of the sliding door 1
The upper end of the lower connection shaft 36 is connected to the lower end of the moving body 47 of the lower frame 45 of the upper and lower frames 45 attached to the substantially central portion in the vertical direction of the upper frame 45, and the upper frame 45 is moved. The lower end of the upper connecting shaft 41 is connected to the upper end of the body 47. Therefore, the handle 46 of the lower frame 45 is turned upside down so as to fit into the upper handle storage groove 45b, thereby lowering the moving body 47 and projecting the lower auxiliary traveling tool 4a downward. Then, the handle 46 of the lower frame 45 is pivoted down and fell down so as to fit into the lower handle storage groove 45b, thereby raising the movable body 47 and pulling the lower auxiliary traveling tool 4a upward. I have.

Further, the handle 46 of the upper frame 45 is turned and turned down so as to be fitted in the lower handle storage groove 45b, thereby raising the movable body 47 and thereby moving the upper auxiliary traveling tool 4b.
Is projected upward, and conversely, the handle 46 of the upper frame body 45 is rotated and tilted upward so as to fit into the upper handle storage groove 45b, thereby lowering the moving body 47 and moving the upper auxiliary traveling tool 4b. It is designed to retract downward. Therefore,
The lower auxiliary traveling tool 6a and the upper auxiliary traveling tool 6b fall out of the openings of the lower rail 3 and the upper rail 2 by turning the upper and lower handles 46 and tilting the handle 46 downward or upward, or It is inserted inside.

The main traveling tool 4 having the sliding door 1 provided above and below one end thereof is mounted on the upper and lower rails 2 and 3 so as to be able to travel freely, and the auxiliary traveling tool is provided from above and below the other end of the sliding door 1. The upper and lower auxiliary traveling tools 6 are inserted into the upper and lower rails 2 and 3 so as to run freely by projecting the sliding door 6, and this state is a state in which the sliding door 1 is slidably mounted along the upper and lower rails 2 and 3.

In this case, the sliding door 1 located at one end
The pinions 5 provided on the upper and lower main traveling tools 4 are engaged with a rack 7 located at one end of the upper and lower rails 2 and 3. Note that the sliding door 1 is parallel to the upper and lower rails 2 and 3 when the auxiliary traveling tool 6 is fitted to the upper and lower rails 2 and 3, but in the explanatory view of FIG. The sliding door 1 is illustrated as being orthogonal to the upper and lower rails 8 for the sake of convenience in explaining the fitting of the auxiliary traveling tool 6 in the description showing the state in which the tool 6 is fitted. The sliding door 1 is parallel to the upper and lower rails 2 and 3 when the traveling tool 6 is fitted to the upper and lower rails 2 and 3.

When the sliding door 1 is rotated (swinged) and opened, first, the upper and lower auxiliary traveling tools 6 are operated by operating the upper and lower handles 46 of the first sliding door 1a in FIG. 3 and in this state the upper and lower main running tools 4
The first sliding door 1a is rotated about the portion as a rotation center as shown in FIG. 2 (rotates substantially 90 degrees with respect to the upper and lower rails 2, 3). Next, the second sliding door 1b is moved to the rack 7
Side, the upper and lower pinions 5 of the second sliding door 1b are moved to an arbitrary position on the rack 7 while being engaged with the upper and lower racks 7, and at this position, the auxiliary traveling tool 6 of the second sliding door 1b is moved. Are removed from the upper and lower rails 2 and 3, and the second sliding door 1 is rotated about the upper and lower main traveling tools 4 as a rotation center. Similarly, the third sliding door 1c also moves to the rack 7 side, and moves to an arbitrary position of the rack 7 in a state where the upper and lower pinions 5 of the third sliding door 1c are engaged with the upper and lower racks 7, and at this position. Then, the auxiliary traveling tool 6 of the third sliding door 1c is removed from the upper and lower rails 2, 3, and the third sliding door 1c is moved to the upper and lower main traveling tools 4.
The part rotates around the center of rotation.

In this way, the sliding door 1 is rotated and opened one after another. In this case, the traveling tool 6 is connected to the upper and lower rails 2,
When the sliding door 1 is rotated while being removed from the sliding door 3, the sliding door 1 is rotated in a state where the upper and lower pinions 5 that rotate in synchronization with the upper and lower racks 7 are rotated, so that the sliding door 1 is prevented from tilting. It can be rotated accurately.

When the sliding door 1 is rotated (swinged) and opened, when the pinion 5 comes to the entrance of the rack 7 and starts meshing, the pinion 5 and the rack 7 are almost simultaneously meshed with each other. A movable body 62 movably provided at the end of the shaft portion 60 hits the introduction inclined surface 63a of the downward projection 64, rides down the downward projection 64 while being pressed downward against the spring force of the spring material 61, and escapes. This is to elastically contact the lower surface of the press-contact protrusion 66 via the inclined surface 63b. The sliding door 1 is rotated and swung as described above in a state in which the front end portion (that is, the upper end portion) of the moving body 62 is in pressure contact with the lower surface of the pressure contact protruding portion 66. After the swing, the distal end portion (that is, the upper end portion) of the moving body 62 is pressed against the lower surface of the press contacting protruding portion 66 by the spring force of the spring material 61, so that the pinion 5 is less likely to move with respect to the rack 7, Further, in order for the pinion 5 to be disengaged from the rack 7, it is necessary to climb over the downward projecting portion 64 having a shorter projecting length than the pressing projecting portion 66. 2 of press contact with the part 66 and getting over the downward projection 64
At this stage, the pinion 5 can be prevented from coming off the rack 7. Therefore, in the swing state, the pinion 5 does not come off the rack 7 and the sliding door 1
Can maintain an accurate posture without tilting.

On the other hand, in order to change from the fully open state in FIG. 3 to the fully closed state in FIG. 1, the operation is performed in the reverse order to the above. In this case, the sliding door 1 is rotated from the swing state to rotate the pinion 5.
The moving body 62 moves toward the downward projecting portion 64 in a state where the moving body 62 elastically contacts the lower surface of the pressing contact base 66 by pulling the sliding door 1 and applying a force to move the moving member 62 in the direction in which the rack 7 is detached from the rack 7. By moving over the downward projection 64 while being guided by the escape inclined surface 63b, the tip of the moving body 62 is in a free state, and the upper main traveling tool 4b can travel smoothly in the upper rail 2.

Next, another embodiment of the present invention will be described with reference to FIG. In the present embodiment, the groove 65 is formed on the lower surface of the press contact base 66 in a direction parallel to the longitudinal direction of the upper rail 2. In the present embodiment, a small projection 62a is provided at the upper end of the moving body 62 so as to project therefrom. In the present embodiment, the small protrusion 62a of the moving body 62 resiliently enters the groove 65 in a state where the moving body 62 has climbed over the downward protrusion 64 and reached the press-contacting base 66. In this case, the small protrusion 62a may enter the groove 65 and the upper end of the small protrusion 62a may resiliently contact the upper bottom surface of the groove 65, or the small protrusion 62a may be in the groove 65. The upper surface protruding from the small protrusion 62a of the moving body 62 at the same time may come into elastic contact with the opening edge of the groove 65). That is, in the swing state in which the moving body 62 is located on the press-contact base 66, the upper end of the moving body 62 presses against the press-contact base 66, and the small protrusion 62 a is in contact with the groove 65.
The pinion 5 is in the upper rail 2 against the rack 7
Is prevented from rattling in the width direction of the upper rail 2 (direction orthogonal to the longitudinal direction of the upper rail 2), and in this regard, the posture of the sliding door 1 in the swinging state can be maintained in an accurate posture.

In the embodiment shown in the accompanying drawings, there is shown an example in which the upper and lower rails 2 and 3 are arranged in two rows, and the plurality of sliding doors 1 in the first row are rotated at the rack 7 as described above. The second row of sliding doors 1 is pivotally opened at the rack 7 as described above. FIG.
3 shows a state in which the plurality of sliding doors 1 in the first row and the plurality of sliding doors 1 in the second row are rotated at the rack 7 and fully opened.

When the upper and lower rails 2 and 3 are arranged in two rows as described above, for example, as shown in FIG. 1A, the sliding doors 1 are arranged on the two upper and lower rails 2 and 3 respectively.
It can be made like a sliding door. In the above embodiment, the example in which the upper and lower rails 2 and 3 are provided in two lines is shown.
Three or more upper and lower rails 2 and 3 may be provided.
Of course, only one upper and lower rails 2 and 3 may be provided.

The racks 7 may be provided on the upper and lower rails 2 and 3 not only at one longitudinal end of the upper and lower rails 2 and 3 but also at both longitudinal ends of the upper and lower rails 2 and 3. Good. In this case, for example, when two vertical rails 2 and 3 are provided, the first vertical rails 2 and 3 are provided with a rack 7 at one end in the longitudinal direction, and the second vertical rails 2 and 3 are long. A rack 7 is provided at the other end in the direction, and the sliding door 1 traveling on the first rails 2 and 3 and the sliding door 1 traveling on the second rails 2 and 3 in the longitudinal direction of the upper and lower rails 2 and 3 are provided. You may make it able to rotate and open separately on both sides.

It should be noted that a rack 7 is provided on the entire length of the upper and lower rails 2 and 3.
It is also conceivable that the upper and lower pinions 5 are meshed with each other, but in this case, even in a place where the sliding door 1 is not rotated, the sliding door 1 is moved along the upper and lower rails 2 and 3 by engaging the rack 7 and the pinion 5. There is a problem that it is difficult to move smoothly when moving by moving. However, according to the present invention, the rack 7 is provided only at the position where the sliding door 1 is rotated, and the rack 7 is not provided at other portions.
At a position where the sliding door 1 travels along the sliding door 3, the sliding door 1 can travel smoothly without engagement between the rack 7 and the pinion 5.

[0033]

According to the first aspect of the present invention, as described above, the main traveling tool is provided on the upper and lower rails above and below the one end of the sliding door so as to be able to run on the upper and lower rails. The tool has a pinion that is rotatable with respect to the sliding door, and the other end of the sliding door has an auxiliary running tool that is fitted into the upper and lower rails so that it can run freely and that can be moved up and down and can be pulled out from the upper and lower rails. There is a rack in which the pinion of the main traveling tool engages only in a part of the direction, so that the auxiliary traveling tool is moved up and down to separate from the upper and lower rails, so that notches are not provided on the front of the upper and lower rails as in the past. Also, the auxiliary traveling tool can be detached from the upper and lower rails, so that the appearance is good, and since the rack where the pinion of the main traveling tool meshes only in a part of the longitudinal direction of the upper and lower rails is provided, By moving the sliding door to the position of the rack and rotating the sliding door at any position of the rack with the pinion engaged with the rack, the upper and lower pinions mesh with the rack and the sliding door is not tilted correctly It can be made to swing. Also, since the rack is provided only in a part of the longitudinal direction of the upper and lower rails, the main traveling tool and the auxiliary traveling tool can be moved smoothly along the upper and lower rails in the part where there is no rack. Also, when the pinion and the rack begin to mesh with each other in the upper rail, a downward projection is provided to allow the distal end of the moving body to jump over while elastically contacting, and moves between the downward projection and the end of the upper rail. Providing a press-contact base having a shorter protruding length downward than the downward protrusion for the distal end of the body to elastically contact, and a side surface on the side opposite to the press-contact base of the downward protrusion as an introduction inclined surface, Since the side surface of the downward projection on the side of the press-contacting base is used as an escape slope, when the pinion starts to mesh from the entrance of the rack and moves along the rack, the moving body guides the introduction slope of the downward projection to the guide. While being pushed down against the spring material, the moving body climbs over the downward projection, and after passing through the downward projection, the distal end of the moving body elastically contacts the lower surface of the press-contacting base portion, thereby pressing the moving body. The pinion can be prevented from coming off the rack in the swinging state and the sliding door can be prevented from tilting by the two-step drop-preventing means of pressing against the platform and climbing down the downward projecting part. Can be held.

According to the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, the groove for moving the upper end portion of the moving body into the press-contacting base portion is provided. Since it is provided, the pinion is prevented from rattling in the width direction of the upper rail, and the meshing state between the pinion and the rack can be reliably maintained in the swing state. As a result, the posture of the sliding door in the swing state Can be maintained in an accurate state.
