Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interlocking sliding door that can be selectively opened and closed on either the left or right side. Each sliding door had the disadvantage that it was not easy to open and close smoothly.

Furthermore, it is inconvenient to use because it can only be opened and closed on either the left or right side.

In addition, conventionally known sliding doors described in Japanese Patent Publication No. 52-33899 etc. are known to have a structure in which when one door is pulled, the other door opens in conjunction, but the two doors are opposite each other. When moving in the direction, only the central part of the entrance always opens and closes, and it is not suitable when it is desired to selectively install the doorway of a building with either a left-hand or right-hand entrance.

Another drawback was that the total width of the door pocket (dead space) was larger than the effective width of the doorway.

The present invention eliminates these drawbacks, has a simple structure, can be manufactured at low cost, can be opened and closed easily and smoothly without any trouble, does not expose the interlocking mechanism, eliminates the risk of injury to hands and feet, and is designed to It can be installed as is at the entrance/exit of either a building with a pull or right-hand pull, leaving only the left side of the entrance wide open.
Alternatively, the purpose is to provide an interlocking sliding door that can be selectively opened wide only on the right side, eliminates the need for separate left and right parts from a production standpoint, and completely standardizes the parts. Its feature is that it is an interlocking sliding door consisting of three front doors, a middle door, and a rear door, and a rotor is rotatably pivoted near the left and right ends of the upper edge of the middle door. Transmission members such as belts, ropes, chains, etc. that can be freely extended and bent are interlocked between the rotors in an endless manner so that both rotors can rotate in conjunction with each other in the same rotation direction. A part of the upper edge of each door is fixed to a symmetrical position of the transmission member with a fixing device, and a fixing device is provided for selectively connecting and fixing the front door and the rear door to the surrounding frame member. be.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

Figures 1, 2, and 3 show an embodiment of the present invention in a closed state, a right-pull state, and a left-pull state, respectively, and Fig. 4 is a cross-sectional view thereof. 1 is a front door, 2 is a middle door, and 3 is a rear door, and these three doors 1.
2.3 is installed.

Moreover, it has a structure without a door pocket. As shown in FIG.
It fits into the rail grooves 11 and 12 of the rail and is suspended while rolling.

15°16, these rollers 9 and 10 are pivotally mounted, and the front door 1
This is a hanging member fixed to the upper edges 17 and 18 of the cutout 3.

Reference numeral 19 denotes a mounting member that is attached to the upper edge 20 of the center opening 2 and has a hanging rod 21 on which the roller 13 is pivotally mounted. It is pivoted around the center so that it can rotate freely.

Reference numeral 22 denotes a lateral vibration prevention roller rotatable around a shaft vertically provided on the suspension members 15 and 16 of the front door 1 and the drawer 3. I was advised to transfer within 23 days.

In addition, the lower frame member 7 has two parallel rail protrusions 24, 24.
is protruding, and of the three doors 1 and 2.3, the front door 1 and the door 3
The doors 1 and 3 are prevented from swinging by sliding while fitting into grooves 25 and 25 formed on the lower edge surface of the door.

Further, a protruding rail portion 26, 26 is formed on the lower edge of the front and back sides of the center opening 2, and is fitted into grooved portions 27, 27 recessed at respective corresponding positions of the front door 1 and the cutout 3. In this way, the center opening 2 slides while being guided by the front door 1 and the cutout 3, thereby preventing the lower edge from swinging laterally.

Therefore, rotors 32 and 33 such as chain wheels 30 and 31 are mounted near the left and right ends 28 and 29 of the upper edge 20 of the center opening 2, and the above-mentioned suspension rod 21 is also used as a pivot shaft, and the rotors 32 and 33 are rotated. The rotors 32 and 33 are freely pivoted, and a transmission member 35 such as a chain 34 that can be freely extended and bent is engaged in an endless manner between the rotors 32 and 33. As shown in the figure, they are connected so that they rotate in the same direction.

36.37 are the upper edges of front door 1 and opening 3, 17° and 18 respectively.
It is a fixing device that fixes and connects a part of the transmission member 35 to a symmetrical position as shown in FIG. 1, and in the closed state shown in FIG. This fixing tool 36,3
As shown in FIGS. 1 to 3, one of the fasteners 36 linearly reciprocates the upper straight part of the loop-shaped endless transmission member 35, and the other fastener 37 moves the lower straight part of the loop-shaped endless transmission member 35. Reciprocate in a straight line and fix the fixture in a loop-shaped symmetrical position 36.37
is located.

In FIG. 4, the fixing device 36 is constructed by a protruding piece 38 protruding from the hanging member 15, and one of the connecting pins of the chain 34 extended and attached to the protruding piece 38 as a connecting pin 39. Although not shown, the other fixing member 37 is similarly composed of a protruding piece from the hanging member 16 and a connecting pin.

40. 41 is a fixing device, which can be detachably attached to the front door 1 and the drawer 3.
are fixed to the vertical members 4 and 5, respectively, so that the front door 1 or the drawer 3 can be held so that they do not move, and can be used by selecting right-hand or left-hand pull as desired, as shown in Figures 2 and 3. It is like that.

In addition, as the transmission member 35, a belt, rope, wire, etc. may be used in addition to the chain 34, and the rotor 3
As for 2.33, you are free to use a pulley or rope wheel.

Further, the transmission member 35 is not limited to being arranged in a loop shape in a plane, but may be arranged in a loop shape in a vertical plane.

At that time, the rotors 32 and 33 are pivotally supported to rotate around the horizontal axis.

In any case, both rotors 32, 33 rotate in conjunction in the same rotational direction.

Furthermore, it is also possible to suspend the center opening 2 by rolling and fitting the suspension rollers 3.13 of the center opening 2 into rail grooves formed in the front door 1 and the cutout 3.

To explain the operation of the interlocking sliding door of the present invention constructed as above, first, move the front door 1 toward the rear door 3 in the direction of arrow A, as shown in FIGS. 1, 2, and 3. If you pull it by hand, the fixing tool 36 will pull the upper straight part of the transmission member 35 to the right even though the fixing tool 41 is fixed, so the rotor 3
2 to the right in the direction of arrow B.

At this time, arrow A. If the moving distance of front door 1 and center opening 2 in direction B is a·S2, then 5=282, and doors 1 and 2 completely overlap door 3 in the open state.

Conversely, if the front door 1 is pulled in the direction opposite to the arrow A, the center opening 2 will move in the direction opposite to the arrow B by a distance above, returning to the closed state shown in FIG. 1.

Next, as shown in FIG. 3, the fixture 40 is fixed to the member 4,
When the puller 3 is pulled in the direction of arrow C, the fixing tool 37 is attached to the transmission member 3.
5 to the left, the rotor 33 is moved in the direction of the arrow.

At this time, if the moving distances of the opening 3 and the opening 2 in the directions of arrows C and D are respectively S3 and S2, it becomes 3-282, and the doors 3 and 2 completely overlap the door 1 in the open state.

Conversely, if the punch 3 is pulled in the direction opposite to the arrow C, the center opening 2 moves in the opposite direction to the arrow C by a distance above, returning to the closed state shown in FIG. 1.

Note that the doors 1 and 3 may be detachably fixed to the upper and lower frame members 6 and 7 using fixtures 40 and 41.

As described in detail above, the present invention effectively achieves the intended purpose, eliminates the need for a put-in space like a door pocket, provides the maximum width of the entrance and exit, and selectively connects the fixtures 40° and 41 to the surrounding frame member. 8, it is extremely useful because it can be opened and closed to the left or right as desired, and can be widely applied from ordinary houses to factories and warehouses.

Furthermore, since the rotors 32, 33 and the transmission member 35 can be completely and compactly housed within the upper frame member 6, it is aesthetically pleasing and there is no risk of injury to the body.

In particular, it can be installed in any entrance/exit area without considering left-handed or right-handed (right-handed or left-handed).
This is an excellent invention because the effective opening width of the doorway can be nearly twice as large as the width of the door pocket (the corresponding fixed door).
