A sliding door device (hereinafter referred to as a flat sliding door) in which a closed sliding door is conventionally arranged on the same plane as another sliding door installed in parallel is disclosed in, for example, Utility Model Application Publication No. 109715/1983, Various proposals have been made, such as No. 33541, but very few have been put into practical use due to their complex structure and the inability to expect reliable and smooth operation. .

In view of the above-mentioned difficulties with flat sliding doors, the present invention was conceived with the aim of providing a flat sliding door that has a simple structure and can operate smoothly and reliably. In a sliding door device that is arranged between the sliding doors so that when one sliding door is closed, the front sides of the sliding door and the other sliding door are all aligned on the same plane, the top of both sides in the width direction of both sliding doors is , on both lower surfaces, running wheels having a bulging shape with an arcuate cross section are provided in a direction parallel to the sliding door, while on the upper and lower stile, on the non-door stop side when the sliding door is closed. The part corresponding to the running wheel located thereon is inclined in the direction in which the sliding door is opened from there to the rear of the stile,
In addition, a diagonal guide groove on the non-door stop side where the side walls of the groove diverge upward, and a straight guide groove slightly parallel to the length direction of the stile in the part corresponding to the running wheel located on the door stop side. A diagonal guide on the doorstop side that forms a shaped groove, communicates with the end of the groove and is inclined toward the side where the sliding door is opened from there toward the rear of the stile, and the side wall of the groove expands upward. grooves, and running guide grooves formed along the longitudinal direction of the stile at the rear of the stile and communicating with the terminal ends of both of the guide grooves; A guided member formed by an inclined side substantially parallel to the oblique guide groove on the non-door stop side and an inverted L-shaped claw piece separated from the side in the vertical direction,
The left and right sliding doors are provided with the vertical relationship reversed to each other, and the terminal ends of the two inclined guide grooves on the non-door stop side at the rear of the upper and lower stiles correspond diagonally to the guided members of the left and right sliding doors. The present invention is characterized in that a guide member is provided on the upper part of the guide member by two sets of guide rolls that respectively guide the inclined side of the guided member and the inverted L-shaped claw piece.

Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 5 show an example in which the device of the present invention is applied to a sliding door. The lower stile 2 and 3 are diagonal guide grooves formed in the right half of the lower stile 1 at an angle with respect to the longitudinal direction of the stile 1 and inclined from the front 1a side of the stile 1 toward the rear 1b. The grooves 2 and 3 have a cross section with the side walls 2a and 3a widened upward.
It is formed in the shape of In this embodiment, the groove 3
has an inclination angle slightly smaller than that of the groove 2, and the outer end of the front side of the stile 1 forms a straight groove part 3.
It is formed in b.

In the left half of the lower stile 1, diagonal guide grooves 21 and 31 are formed which are symmetrical in plan to the diagonal guide grooves 2 and 3 and which guide the other sliding door.
In addition, 21a and 31a are the side walls of the guide grooves 21 and 31,
31b is a straight groove portion connected to the groove 31. Reference numeral 4 denotes a running guide groove at the rear of the lower stile 1, communicating with the rear end side of each of the grooves 2, 3, 21, and 31 and recessed between the rear ends of the grooves 3 and 31;
With the above steps, the basic structure of the lower stile 1 is formed.
Note that 2b, 21b, 3c, and 31c are depressed portions of running wheels (described later) that are recessed in front of the oblique guide grooves 2, 21, 3, and 31.

On the other hand, as shown in FIG. 2, the upper stile 5 has the same shape as the lower stile 1 and the same shape as the guide grooves 2, 21, 3, 31 and 4 in this embodiment. Guide grooves 2', 21', 3', 31' and 4' are provided.

Between the stiles 1 and 5 configured as described above, two sliding doors 6 and 61 are arranged so that in the closed state, they are parallel to both stiles and the front surfaces of both sliding doors are in the same plane. However, on the lower surface of both sliding doors 6, 61, there are running grooves parallel to the running guide groove 4 at positions corresponding to the wheel drop portions 2b, 3c, 21b, 31c of the lower stile 1, respectively. Wheels 7, 8, 71, 81 are provided.

The running surfaces 7a, 8a, 71a, 81a of each of the wheels 7, 8, 71, 81 described above are formed to have an arcuate cross section. When sliding obliquely in the oblique guide grooves 2 and 3 having a square cross-section at the beginning of opening, the running surfaces 7a and 8a move along the left side walls 2a and 3 of the grooves 2 and 3, respectively.
This is to rotate the running wheels 7 and 8 by contacting the wheels 3a. When the sliding doors 6, 61 move obliquely, in order for the wheels to rotate within their oblique guide grooves, the side walls of each groove need only have a shape that expands upward.

On the other hand, in this embodiment, wheels 7', 8', 71', 81' similar to the traveling wheels 7, 8, 71, 81 are provided on the upper surface of the sliding doors 6, 61. . These wheels are different from the aforementioned traveling wheels in that they do not receive the load from the respective sliding doors 6, 61, but they are different from the aforementioned running wheels in that they do not receive the load from the respective sliding doors 6, 61, but the wheels are different from the aforementioned running wheels in that they do not receive the load from the respective sliding doors 6, 61, but they are attached to the respective diagonal guide grooves 2', 3', 2 of the upper stile 5.
The action on wheels 1' and 31' is similar to that on the traveling wheels. 9 and 91 are provided with a horizontal support plate 9b protruding toward the front of the lower stile 1 from a support member 9a erected at the rear of the lower stile 1 in the longitudinal direction, and in front of the plate 9b. Two guide rolls are rotatably provided on the upper and lower surfaces of the plate 9b above the terminal ends of the oblique guide grooves 2 and 21 of the lower stile 1 via vertical shafts 9b, respectively.
As will be described later, the first guide roll 9 ensures the oblique movement at the end of one sliding door 6 when the door is closed, and prevents the other sliding door 61 from accidentally entering the oblique guide groove 2 at the beginning of straight movement. The guide roll 91 functions as an abutting member that ensures the oblique movement of the other sliding door 61 at the end when the door is closed, and prevents the one sliding door from accidentally entering the oblique guide groove 21 at the beginning of the straight movement.

Reference numeral 10 denotes a guided member that is provided on the back surface of one of the sliding doors 6 corresponding to the roll 9 on the starting end of the oblique guide groove 2, and is guided obliquely when it is in contact with the roll 9. Sloped side 10 above and parallel to the diagonal guide groove 2 of the lower stile when viewed from above
a, and an inverted L-shaped claw piece 10b positioned with a gap 10c below the side, and when closing the sliding door, the running wheels 7 and 8 are removed from the running guide groove 4, respectively. When opening the sliding door 6, the pawl piece 10b enters the opposite side of the guide roll 91 located on the end of the diagonal guide groove 21 and is guided. This prevents the wheels 7 of the sliding door 6 from entering the other oblique guide groove 21 by mistake.

Reference numeral 11 denotes a guided member provided on the back surface of the other sliding door 61 on the non-door stop side, which has an inclined side 11a and an inverted L-shaped claw piece 11b having the same shape and structure as the member 10 on the sliding door 61 side. The member having the above member 1
0 is attached to the sliding door 61 with the vertical relationship reversed.

This is because the guide roll 91 that guides the inclined side 11a of the guided member 11 is provided on the lower surface of the support plate 9b, and the roll 9 that guides the inverted L-shaped claw piece 11b of this member is provided on the support plate 9b. This is because it is provided on the top surface.

Therefore, the guide roll 91 abuts and guides the inclined side 11a of the guided member 11 near the closing end of the sliding door 61, thereby closing the sliding door 61.
While forcing the wheels 71 and 81 to move to the diagonal guide groove 2, the guide roll 9 also forces the wheels 71 and 81 to move into the diagonal guide groove 2 so that the wheels 71 do not erroneously move into the other diagonal guide groove 2 at the beginning of opening the sliding door 61. By being held by the letter-shaped claw piece 11b, it guides the sliding door in a diagonal or straight direction.

The upper stile 5 and the sliding doors 6, 61 are provided with two guide rolls (not shown) similar to the above-mentioned guide rolls 9, 91 and the corresponding guided members 10, 11, and these rolls. A corresponding guided member (not shown) is provided, each of which corresponds to the above-mentioned sliding door 6.
a guide roll 9 and a guided member 10, and
Guide roll 91 and guided member 1 regarding sliding door 61
1 to ensure that the sliding door 6 or 61 slants at the end of closing.

The operating mode of the device of the present invention constructed as described above will be explained below by taking the sliding door 6 as an example.

When both sliding doors 6 and 61 are in a closed state,
The running wheels 7, 8, 71, 81 of 6, 61 are located on the front end side (the front 1a side of the lower stile) of the diagonal guide grooves 2, 3, 21, 31, respectively.
b, 3c, and the front surfaces of the sliding doors 6, 61 are flush with each other. In addition, each wheel 7', 8', 71', 81' on the upper stile 5 also has a diagonal guide groove 2',
It is located on the front end side of 3', 21', and 31'.

Now, when you grab the handle 6h of the sliding door 6 and pull it to the left in FIG. (At this time, the running wheel 8 is in the straight groove 3b.) However, the wheel 7 that has come into contact with the side wall 2a is because its running surface 7a has an arcuate cross section, and this wheel 7 is in contact with the side wall 2a. Since the contacting side wall 2a is inclined in the expanding direction of the groove 2, the oblique guide groove 2
It rotates in the direction of travel while moving diagonally. On the other hand, the traveling wheel 8 located on the side of the handle 6h also enters the diagonal guide groove 3 after traveling a short distance in the straight groove 3b, and rotates in the diagonal guide groove 3 in the same manner as the wheel 7. go That is, the sliding door 6 begins to open and moves obliquely within the oblique guide grooves 2 and 3 due to the rotation of the wheels 7 and 8. In addition, wheels 7' provided on the top surface of the sliding door 6,
Similarly to the wheels 7 and 8, the wheels 8' also move within the oblique guide grooves 2' and 3'.

In this way, the running wheels 7 and 8 of the sliding door 6 reach the rear ends of the oblique guide grooves 2 and 3 and reach the running guide groove 4, but a force is still applied to the sliding door 6 in the direction of opening the sliding door. Therefore, the wheels 7 and 8 of the sliding door 6 run while rolling in the travel guide groove 4, and the sliding door 6 is positioned on the back side of the other sliding door 61 to open the door, similar to a conventional sliding door. . Incidentally, each wheel 7', 8' on the upper stile 5 also operates along the guide groove 4'.

In the above, the sliding door 6 has its oblique guide grooves 2 and 3.
When reaching the traveling guide groove 4 from above, the guided member 10 provided on the back surface of the sliding door 6
A gap 10 formed between a and the claw piece 10b
Since the guide roll 91 passes through the part c, the guide roll 91 protruding from the front side of the lower stile 1
does not obstruct the movement of the sliding door 6. At this time, the vertical wall portion of the claw piece 10b is guided by the roll 91 and assists the sliding door 6 to move straight in this portion. In other words, the wheel 7 is prevented from entering the other oblique guide groove 21 erroneously.

This also applies to a member similar to the roll 91 provided on the upper stile 5 and a member similar to the guided member 10 provided with the sliding door 6.

To close the sliding door 6 that has been opened as described above, grasp the handle 6h and pull the sliding door 6 to the right in the figure. When the sliding door 6 is pulled in the closing direction, the running wheels 7 and 8 rotate on the running guide groove 4, so that the wheels 7 and 8 are connected to the rear end portions of the oblique guide grooves 2 and 3, respectively. The guided member travels straight along the guide groove 4 until it reaches the connecting portion between the guide grooves 2 and 3 and the traveling guide groove 4. However, when the handle 6h is further pulled toward the closing side in this state, the guided member The ten inclined sides 10a contact the protruding guide roll 9, preventing the sliding door 6 from moving straight on the running guide groove 4, and at the same time, the sliding door 6 tilts along the inclination angle of the inclined side 10a. start going.

Since the sliding door 6 begins to move diagonally when its wheels 7 and 8 are located at the rear ends of the skew guide grooves 2 and 3,
The running wheels 7, 8 easily and smoothly move from the running guide groove 4 into the oblique guide grooves 2, 3, and as a result, even if the inclined piece 10a separates from the guide roll 9,
The running wheels 7, 8 rotate while contacting the right side walls 2a, 3a of the respective diagonal guide grooves 2, 3, and the sliding door 6 can be smoothly tilted toward the front side 1a of the lower stile 1. .

Furthermore, since the wheels (not shown) of the sliding door 6 on the upper stile 5 operate in the same pattern in synchronization with the wheels 7 and 8, the sliding door 6 will not wobble at all.
To continuously perform diagonal motion while traveling straight without tilting.

Although the above example of operation has been described only for one sliding door 6, the other sliding door 61 is also omitted because its operation mode is the same except that the opening/closing direction is different from that of the sliding door 6.

Furthermore, in the above embodiment, a case was described in which two sliding doors were installed oppositely, but the present invention
Alternatively, it is of course possible to implement it in a place where a wall or the like is fixedly provided in the same position as when 61 is closed.

The present invention is as described above, and is a sliding door that is arranged between the upper and lower stiles so that when one sliding door is closed, the front sides of the sliding door and the other sliding doors are all aligned on the same plane. In the device, running wheels having a bulging arc-shaped cross section are installed on the upper and lower surfaces of both sides in the width direction of the sliding door, and the running wheels are installed near the end of closing of the sliding door. The diagonal guide grooves provided in the upper and lower stile to guide the diagonal movement of the sliding door are made to have a shape that expands toward the top so that the cross section is approximately 〓 shape. In a portion where the running wheels are located at the rear end of the diagonal guide groove when the sliding door is closed on the rear end side, on the back side of the sliding door and the rear side of the stile,
Since the sliding door device is constructed by relatively protruding the guide roll and the guided member having the inclined piece that is guided in contact with the roll, the number of parts is extremely small compared to this type of sliding door device that has been proposed in the past. The advantage is that it is possible to provide a so-called flat sliding door that operates smoothly and reliably and is easy to manufacture and at low cost.

In particular, in the sliding door device of the present invention, the planar pattern of the guide groove is similar to that previously proposed;
The diagonal guide groove has a cross-sectional shape with the side wall expanding upward, and the running surface of the running wheels guided by the groove has an arc-like bulge in cross section. Even when the vehicle is traveling diagonally, the wheels are brought into contact with the side wall and rotated, and smooth diagonal travel can be achieved with a simple structure, an effect not found in conventional products, which is extremely useful. Furthermore, in the device of the present invention, the guide grooves and guide members of the upper and lower stile have a common structure, and the wheels of the sliding door have the same structure on the upper and lower sides. Structures and parts can be standardized, and assembly can be easily done without having to take into account the stock of parts or the orientation of materials during manufacturing and assembly.This, combined with the reduction in the number of parts, makes it easier to manufacture than before. It is more advantageous than other products.
