Description

The present invention relates to a method for adjusting an opening and closing door device, which adjusts the positional relationship between an upper rail that guides the door body in the opening and closing direction on the upper side, and a lower rail that guides the door body in the opening and closing direction on the lower side.

Conventional door opening and closing devices include, for example, those described in Patent Document 1, which are equipped with a door body that opens and closes in the opening width direction, an upper rail that guides a hoist attached to the upper part of the door body in the opening and closing direction, and a lower rail that guides a lower car attached to the lower part of the door body in the opening and closing direction.
When such an opening and closing door device is installed in an opening in the framework of a building or the like, if the parallelism between the upper rail and the lower rail is not appropriate, there is a risk of problems with the opening and closing operation.
Therefore, in the conventional construction method, the installer would slowly open and close the door body between the upper and lower rails and determine by intuition whether the parallelism of the upper and lower rails was appropriate.

However, with the conventional construction method described above, the parallelism between the upper and lower rails can vary depending on the construction worker, site conditions, etc.

In view of the above problems, the present invention has the following configuration.

<Specific embodiment>
Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings.
In this specification, the term "visible direction" refers to the width direction of the frame body (the left-right direction in FIG. 1). The term "visible direction" refers to the direction of the frame thickness that is approximately perpendicular to the "visible direction."
Furthermore, the "opening width direction" refers to the lateral width direction of the opening that is opened and closed by the door body, and in this embodiment, this is the same direction as the "finding direction."
Furthermore, the "door thickness direction" refers to the direction of the thickness of the door body, which in this embodiment is the same direction as the "front direction."

1 and 2 show an example of an opening and closing door device to which the opening and closing door device adjusting method according to the present invention is applied.
The opening and closing door device 1 is configured to open and close an opening A, which penetrates a vertically long rectangular wall of a building or the like, in the width direction by a door body 10 (see Figs. 1 and 2).

The opening and closing door device 1 is a sliding door device comprising a door body 10 that moves in the opening width direction to open and close the opening A, a door-end side vertical frame 20 that faces the door end of the door body 10, a lower rail 31 that guides the door body 10 in the opening and closing direction on the lower side, and a transom 40 that incorporates an upper rail 46 that guides the door body 10 in the opening and closing direction on the upper side.
This opening and closing door device 1 is provided with a device for automatically closing or automatically opening the door body 10, a damper device for reducing the closing speed or opening speed of the door body 10, etc. as required.

The door body 10 is a member that opens and closes in the width direction of the opening.
The door body 10 comprises a front panel 11 and a back panel 12 (see FIG. 3) that are spaced apart in the door thickness direction and are generally parallel to each other, and a plurality of frames that secure the front panel 11 and the back panel 12 together on the inside.

Of the multiple frames, the uppermost one is a horizontal frame 13 that spans almost the entire width of the door body 10. A hoist 14 that suspends the door body 10 and rolls on the upper rail 46 is supported on the top surface of this horizontal frame 13.

The hoist 14 is arranged at the top of the door body 10 on the door tip side.
The hoist 14 is supported at the upper end of the door body 10 via a bracket 15 or the like so as to rotate about an axis in the door thickness direction. The hoist 14 protrudes upward from the door body 10 and engages with an upper rail 46.

In addition, a recessed groove 16 that opens downward and extends across the width of the door is provided at the lower end of the door body 10 (see Figure 4). A carriage 17 is supported within this recessed groove 16 so that it protrudes downward from the trailing edge of the door body 10.

The recessed groove 16 supports the undercarriage 17, wheel-off prevention member 16a, airtight material 16b, etc. via brackets, etc.

The lower carriage 17 rotates freely around a rotation axis in the door thickness direction as a fulcrum, and rolls on the lower rail 31.
The wheel-off prevention member 16 a is a member having a substantially L-shaped vertical cross section, and is configured to engage with a wheel-off prevention locking portion 33 integral with the rail 31 when the dismounting vehicle 17 moves upwardly away from the rail 31 .
The airtight material 16b protrudes downward from the door body 10 across the door width direction and contacts the lower immovable surface F, and is supported so as to be movable up and down.

In Figure 1, reference numeral 18 denotes a handle for opening and closing the door body 10, and reference numeral 19 denotes a keyhole or thumb turn for the locking device.

The door-end vertical frame 20 is a long, columnar member that extends vertically and is fixed to the wall surface of the main body along the left edge of the opening A.
This door-end vertical frame 20 has a continuous groove in the vertical direction on the surface facing the door body 10 so that the door end of the door body 10 can fit into it.

The lower rail 31 is fixed to the lower stationary surface F on the door trailing edge side of the upper rail 46 by detachable fixing means such as screws or bolts.
The lower rail 31 is formed in a long shape that protrudes from the lower immovable surface F and continues in the door body opening and closing direction.
One end of the lower rail 31 is located closer to the tail end of the door body 10 in the fully closed position (see Figure 1) and closer to the door tip than the lower carriage 17, and the other end of the lower rail 31 is located closer to the tail end of the door body 10 in the fully open position (see Figure 2) and closer to the tail end than the lower carriage 17.

In the example shown in Figure 4, the lower stationary surface F is a metal sliding member fixed to the floor surface or the like across the opening and closing range of the door body 10. As another example of this lower stationary surface F, it could also be the floor surface itself.

A wheel-off prevention locking portion 33 is fixed to the lower rail 31 so as to engage with the wheel-off prevention member 16 a of the door body 10 .
This anti-wheel slippage locking portion 33 is a member with an inverted L-shaped cross section that continues in the opening width direction along the lower rail 31, and the portion that protrudes in the door thickness direction is positioned above the lower end piece of the anti-wheel slippage member 16a (see Figure 4).

In addition, a lower anti-sway member 32 is provided on the lower stationary surface F, closer to the door tip than the lower rail 31. This lower anti-sway member 32 is a roller supported on the lower stationary surface F so that it rotates around a vertical axis, and is loosely fitted into the recessed groove 16 to prevent the lower end of the door body 10 from swinging in the door thickness direction.

The transom 40 is configured to be long in the width direction so as to cover the upper end portion of the door body 10 in the fully closed state over the entire length in the opening and closing direction.
As shown in Figure 3, this door frame 40 comprises a base 41 that supports the upper rail 46 and is attached to the wall W, and a front cover member 44 that is removably attached to the base 41 and covers the upper end of the door body 10 and the hoist 14, etc. from the front side.

In Figure 3, reference numeral 21 denotes a vertical frame member that covers the vertical edge of opening A in the vertical direction, reference numeral 22 denotes an upper frame member that covers the upper horizontal edge of opening A, and reference numeral 23 denotes an airtight material that elastically contacts the back surface of the upper end of the door body 10 in the opening and closing direction.

The base 41 is a long, fixed member that extends along the upper wall surface w1 of the opening A in the width direction of the opening.
This base 41 integrally comprises a rail side base member 41a to which the upper rail 46 is attached, a wall side base member 41b which is fastened to the wall portion W, and a top member 41c which covers the upper part of the upper rail 46 and the hoist 14 etc.

The rail-side base member 41a has a substantially vertical, flat base plate portion 41a1 to which the upper rail 46 is attached. This base plate portion 41a1 is continuous and elongated across the width of the opening.

The wall-side base member 41b is a member that extends in an elongated shape in the opening width direction above the opening A so as to cover a part of the outdoor-side wall surface w1.
The wall-side base member 41b is fixed to the wall W by well-known fixing means such as screws, rivets, or welding.
3, reference numeral 41d denotes a fastening member such as a screw that fastens the stacked wall-side base member 41b and top member 41c to the wall surface w1. Reference numeral 41e denotes a substantially cylindrical anchor member embedded in the wall portion W for screwing in the fastening member 41d.

In addition, the top member 41c is formed in an approximately L-shaped vertical cross section from a fastening piece portion 41c1 that is superimposed on and fastened to the wall side base member 41b and a top plate portion 41c2 that protrudes from the upper end of the fastening piece portion 41c1 toward the outdoors, and is continuous in a long shape in the opening width direction.
This top member 41c can also be formed as an integral member with the wall-side base member 41b or the rail-side base member 41a.

The rail-side base member 41a and the wall-side base member 41b are integrally formed with the fastening piece 41c1 of the top member 41c sandwiched therebetween (see FIG. 3).
The rail-side base member 41 a and the top member 41 c are detachably connected to the wall-side base member 41 b. This connection may be achieved by means of screws, for example, but may also be achieved by rivets that can be removed by cutting, or by detachable fittings.

The wall portion W is a wall of the building or other structure on which the opening and closing door device 1 is to be installed, and is made of concrete, mortar, or the like. Anchors (not shown) for fixing the wall-side base member 41b, upper frame member 22, etc. are embedded in this wall portion W as necessary.

In Figure 3, reference numeral 101 denotes the ceiling of the frame on which the door opening/closing device 1 is installed, reference numeral 102 denotes the outer wall of the frame, reference numeral 103 denotes a batten-shaped member attached to the wall W so as to cover the upper end of the base 41, and reference numeral 104 denotes a filler that covers the batten-shaped member 103 and seals the gap between the lower end of the outer wall 102 and the ceiling member 41c.

An upper rail 46 is provided on the base 41 so as to protrude from the base plate 41a1 and continue in the opening width direction.
The upper rail 46 is a long member with an approximately L-shaped longitudinal cross section that continues in the opening width direction, with one vertical end attached to the base plate portion 41a1 and the other end protruding horizontally from the base plate portion 41a1 on which the hoist 14 is placed and engaged (see Figure 3).
The length of the upper rail 46 is set so as to include the range in which the hoist 14 moves as the door body 10 opens and closes.
In the drawing, reference numeral 41f denotes fasteners (for example, screws, bolts, etc.) that fasten the upper rail 46 to the base plate portion 41a1.

Next, a method for adjusting the opening and closing door device according to the present invention, which is targeted at the opening and closing door device 1, will be described.
This method for adjusting the door-opening/closing device can be applied to positioning the lower rail 31, which is fixed later, approximately parallel to the upper rail 46, which has been fixed earlier, when assembling the door-opening/closing device 1 and installing it in an opening in the structure of a building or the like, or when maintaining the door-opening/closing device 1 after installation.

In the example shown in Figures 5 to 7, the door-end vertical frame 20, vertical frame member 21, transom 40, lower rail 31, and lower immovable surface F, which is the door slide member, are assembled as a single unit in a factory. After these are installed in an opening in the structural frame of a building, etc., the lower rail 31 is loosened and the position of the lower rail 31 relative to the upper rail 46 is adjusted.

Note that "substantially parallel" refers to the upper rail 46 and the lower rail 31 being substantially parallel when viewed from above or below. In other words, in this "substantially parallel" state, the distance between the upper rail 46 and the lower rail 31 in the projected direction is substantially the same at the leading edge and trailing edge.

This door opening/closing device adjustment method includes a first step of installing the laser emission device X so that the optical path plane P is close to or in contact with the upper rail 46 and the lower rail 31 (close in the example shown in Figure 6(a)), a second step (see Figure 6(b)) of adjusting the position of the laser emission device X so that the upper rail 46 and the optical path plane P are parallel, and a third step (see Figure 6(c)) of adjusting the position of the lower rail 31 so that it is parallel to the optical path plane P.

The laser emitting device X is a device that emits visible laser light in a vertical line. As this laser emitting device X, a well-known laser emitting device such as a laser marking device can be used.
The visible laser light emitted from this laser emission device X is a visible ray of a single wavelength, and forms a vertical, flat optical path surface P as shown in FIG.

In the first step, the upper rail 46 is fixed to the base 41, and the lower rail 31 and the like are fixed to the lower stationary surface F. Then, the laser beam emitter X is installed on one side of the opening A in the opening width direction (see FIG. 6(a)).
According to the illustrated example, the laser emission device X is placed on the floor or the like at a position closer to the door end than the installation space of the lower rail 31, and at a position away from the upper rail 46 and the lower rail 31 in the forward direction so as to emit visible laser light.

When a specific switch is turned on, the laser emission device X emits visible laser light in a vertical line. This visible laser light forms an optical path plane P that follows both the upper rail 46 and the lower rail 31 at a distance. In other words, the optical path plane P is a vertical, flat surface formed by the optical path of the visible laser light.

In the illustrated example, the optical path surface P is close to (not in contact with) both the upper rail 46 and the lower rail 31, but other examples of this first step include having the optical path surface P close to either the upper rail 46 or the lower rail 31 and in contact with the other, or having the optical path surface P in contact with both the upper rail 46 and the lower rail 31.

In the second step, the distance from the optical path plane P to a predetermined position on the door edge side of the upper rail 46 and the distance from the optical path plane P to a predetermined position on the door edge side of the upper rail 46 are measured (see Figure 6(b)), and the position of the laser emission device X is adjusted so that these two distances approximately match. Here, in the illustrated example, the predetermined position is the tip of the part of the upper rail 46 that protrudes from the base 41.

This position adjustment can be performed by rotating the laser emitting device X around a vertical axis so as to change the emission direction of the visible laser light in the projection direction, or by moving the laser emitting device X in the projection direction so that the distance between the optical path surface P and the upper rail 46 becomes appropriate.
When the two distances are approximately equal, the optical path plane P and the upper rail 46 are considered to be parallel.

In the third step, the fasteners 34 (screws, bolts, etc.) that secure the lower rail 31 to the lower immovable surface F of the door sill, etc., are loosened, allowing the lower rail 31 and the anti-slip locking portion 33 to move in the forward direction.
Then, the distance from the optical path plane P to a predetermined position on the door edge side of the lower rail 31 and the distance from the optical path plane P to a predetermined position on the door edge side of the lower rail 31 are measured (see Figure 6(c)), and the position of the lower rail 31 is adjusted so that these two distances match. In the illustrated example, the predetermined position is the tip position of the part of the lower rail 31 that protrudes upward from the lower fixed surface F.
When these two distances are approximately equal, the optical path plane P and the lower rail 31 are considered to be parallel.

In the second or third step, a linear straightedge L is used to measure the distance.
That is, in the second step, the worker or the like places a part of the straight edge L (the end in the illustrated example) against the upper rail 46 and holds the straight edge L so that it is approximately perpendicular to the upper rail 46, and places the other part of the straight edge L in the optical path plane P and reads the scale of the straight edge L indicated by the visible laser light (see Figure 6(b)), thereby measuring the dimension between the one part and the other part.
This operation is performed for both the leading edge side portion and trailing edge side portion of the upper rail 46. Then, the laser beam emitting device X is moved and positioned so that the distance at the leading edge side portion and the distance at the trailing edge side portion are approximately the same.

In the third step, the worker places a part of the straight edge L (one end in the illustrated example) against the lower rail 31 placed on the lower immovable surface F, holding the straight edge L at approximately a right angle to the lower rail 31, and places the other part of the straight edge L in the optical path plane P, and reads the scale of the straight edge L indicated by the visible laser light (see Figure 6 (c)), thereby measuring the dimension between the part and the other part.
This operation is performed for both the leading edge and trailing edge portions of the lower rail 31. Then, the lower rail 31 is moved and adjusted in position so that the distance between the leading edge and trailing edge portions is approximately the same.

The lower rail 31 is then fixed immovably to the lower fixed surface F by tightening the loosened fasteners 34 (screws, bolts, etc.).

Therefore, according to the method for adjusting an opening and closing door device of the present invention, the work of installing the lower rail 31 substantially parallel to the upper rail 46 can be performed efficiently and with high precision.
In particular, in the illustrated example of the opening and closing door device 1, the upper rail 46 and the lower rail 31 are positioned apart in the opening and closing direction, but according to the present invention, the parallelism of the upper rail 46 and the lower rail 31 can be adjusted with high precision even in such a positional relationship.

<Modification>
Next, a partially modified embodiment of the above-mentioned method for adjusting an opening and closing door device will be described.
7(a) and 7(b) show another example of the method for adjusting an opening and closing door device according to the present invention.
In this door opening and closing device adjusting method, in the second step described above, the position of the laser emitting device X is adjusted without using the straightedge L so that the optical path surface P is in contact with the upper rail 46 in a substantially parallel manner.

Explaining in more detail, in this second step, the laser emission device X is adjusted so that a predetermined position on the door leading side of the upper rail 46 (in the illustrated example, the tip in the door thickness direction) is in contact with the optical path surface P, and a predetermined position on the door trailing side of the upper rail 46 is also in contact with the optical path surface P. In other words, the laser emission device X is moved so that the tip of the upper rail 46 is in contact with the optical path surface P over the entire extension direction of the upper rail 46.

Then, in the third step, the lower rail 31 is placed on the lower fixed surface F, and the distance from the optical path surface P to a predetermined position on the door edge side of the lower rail 31 (in the illustrated example, this is the upper end of the lower rail 31 on the door edge side) and the distance from the optical path surface P to a predetermined position on the lower rail 31 on the door tail side of the predetermined position on the door edge side (in the illustrated example, this is the upper end of the lower rail 31 on the door tail side) are measured using a straight edge L, and the lower rail 31 is moved and fixed so that these two distances match.

In the measurement operation, a part of the straight edge L (the lower surface at the tip end in the example of Figure 7) is brought into contact with the upper end of the lower rail 31, and the other part of the straight edge L (the tip end in Figure 7) is placed in the optical path plane P.
The worker or the like looks at the straightedge L from the side and reads the scale on the straightedge L to measure the dimension between the one portion and the other portion.

Therefore, with the door opening/closing device adjustment method shown in Figure 7, the second step can be carried out without hitting the straightedge L against the base 41, which is located at a relatively high position, making the work easier.

In the above embodiment, the lower rail 31 is provided closer to the door tail than the upper rail 46, but the door opening/closing device adjustment method of the present invention can also be applied to door opening/closing devices in which the lower rail is provided directly below the upper rail.

Furthermore, in the above embodiment, the laser emission device X is installed closer to the tail end of the door than the opening/closing door device 1 in the opening width direction. However, as another example, the laser emission device X can also be installed closer to the front end of the door than the opening/closing door device 1 in the opening width direction.

In addition, in the above embodiment, a linear straight edge L is used, but as an alternative, it is possible to use a ruler other than the straight edge L shown in the illustration, such as a triangular ruler, T-square, or right-angle ruler, instead of the straight edge L.

In addition, in the above embodiment, the door body 10 is guided between the upper rail 46 and the lower rail 31 in the opening width direction to perform the opening and closing operation. However, the opening and closing door device adjustment method of the present invention can also be applied to opening and closing door devices other than the illustrated example that have upper and lower rails, such as a folding door device that opens and closes by folding and unfolding the door body between the upper and lower rails, or a balanced door device that opens and closes by moving the door body on the door front side in the opening width direction while rotating between the upper and lower rails.

Furthermore, the present invention is not limited to the above-described embodiments, and modifications can be made as appropriate without departing from the spirit of the present invention.
