Description

[Detailed Description of the Invention] The present invention relates to a door installed at the entrance/exit of a building, and particularly relates to a hanging type sliding door.

Suspended sliding doors, which are used in buildings such as factories, generally have a hollow mounting bracket fixed to the wall above the entrance, and a door roller that can move freely on a rail installed inside the bracket. The door body is connected to a hanging bolt that hangs down, and the door body is opened and closed by pushing the door body by hand when people, cars, etc. enter or exit.

However, since such sliding doors are manually operated, they are not suitable for large doors or places with frequent access.

On the other hand, automatic sliding doors have recently become popular. This uses a drive source such as a motor to open and close a door connected to it via a transmission member such as a chain or belt, but its installation location must actually be the entrance of a new building. .
This is because in order to automate a door, it is necessary to install a drive device, etc., which requires major modifications such as replacing the existing mounting bracket, which requires a lot of effort and cost.

The present invention has been developed in view of the above circumstances, and its purpose is to add the minimum number of elements to the existing manual door device, thereby achieving door automation at minimum cost.

Another purpose of the present invention is to provide a door device that can be used as a manual door by simply removing elements for automation such as a driving device for entrances and exits that do not require an automatic door. be.

According to the present invention, there is a hollow mounting bracket that is attached to the upper part of the entrance of a building, a rail disposed within the mounting bracket, a door roller that is movably disposed on the rail, and a hanging bolt that hangs from the door roller. In a hanging sliding door comprising a door body suspended by a connecting piece having a bolt attachment part, a pressing piece for fixing the connecting piece to a mounting bracket, and a pressing piece for driving the door body to open and close. The device further includes a drive unit, a door connecting member, and a power transmission member for transmitting the driving force from the drive unit, and the connecting piece is fixed to the outer surface of the mounting bracket by screwing the pressing piece to the mounting bracket. , the drive unit is attached to the bolt attachment part, the door connecting member is attached to the upper end of the door body, the power transmission member drivingly connected to the drive unit is connected to the door connecting member, and the door connecting member is attached to both upper and lower ends. Consisting of a plate material whose portion is bent substantially vertically and whose middle portion extends approximately horizontally, the downwardly bent corner portion has a
A long hole whose width is slightly larger than the outside diameter of the hanging bolt is formed, and the hanging bolt is inserted into the long hole and the door connecting member is held between two nuts positioned above and below the long hole. A hanging sliding door is provided, characterized in that a connecting member is fixed to the door body.

Hereinafter, specific examples of the present invention will be described with reference to the accompanying drawings.

First, FIG. 1 is a cross-sectional view of an existing manual sliding door. A rail 6 disposed within the mounting bracket 4, a door roller 8 disposed movably on the rail, and the door roller 8.
The door body 14 is connected to the bolt 10 by having its upper end held between upper and lower nuts 12a and 12b at the lower end of the hanging bolt 10 hanging from the door. A steady rest 16 is provided at the lower end of the door body 14 to prevent the door body from swinging in a direction perpendicular to its surface.

According to the present invention, the manual sliding door is automated as follows. This is shown in Figures 2 to 4.
Referring to the drawings, first, a plate-shaped connecting piece 18 is fixed to the outer surface of the mounting bracket 4, extending along its longitudinal direction. This connecting piece 18
As shown in FIG. 3, there are two upper and lower bolts 22 for fixing the drive unit 20, which will be described later, in a predetermined position (for example, near one end of the mounting bracket 4).
It has bolt mounting parts 24a and 24b that house the heads of each of bolts a and 22b and support each bolt substantially horizontally. The pair of upper and lower bolt attachment portions 24a and 24b protrude above the connecting piece 18, respectively, and form grooves 26a and 26b into which the heads of the bolts 22a and 22b are laterally inserted. Further, as shown in FIG. 2, the connecting piece 18 has a mounting portion 32 for a reed switch holder 30 holding a reed switch 28 for detecting the position of the door body 14 at a predetermined position near its lower edge. The upper and lower edges of the mounting portion 32 protrude from the surface of the connecting piece 18 at an appropriate distance, and the reed switch holder 30 has two upper and lower elastic arms that extend laterally and have hook-shaped tips. It is attached to the attachment part 32 by engaging the pieces 31a and 31b so as to sandwich both upper and lower edges of the attachment part 32. The reed switch holder 30 preferably elastically holds the reed switch 28 in a removable manner using two elastic arm pieces 31c and 31d extending in the vertical direction.

In the illustrated example, the connecting piece 18 is
It is fixed to the outer surface of the mounting bracket 4 by pressing its upper and lower edges with pressing pieces 34 and 36 screwed to the mounting bracket 4. More specifically, the mounting bracket 4 has threaded holes in the upper and outer bottom walls of the mounting bracket 4, and setscrews 38 and 40 that fit into these threaded holes, respectively, so that the mounting bracket 4 has edges bent at a substantially right angle. Two pressing pieces 34 and 36 are pressed against the mounting bracket 4. Therefore, by engaging and pressing the bent edges of the pressing pieces 34 and 36 with the upper and lower edges of the connecting piece 18, the connecting piece 18 is fixed in close contact with the mounting bracket 4. . and,
When fixing the connecting piece 18, use the mounting bracket 4.
It is sufficient to simply drill appropriate screw holes in advance at predetermined positions.

Next, a door connecting member 42 is coupled to the upper end of the door body 14. As clearly shown in FIG. 4, this door connecting member 42 has upper and lower ends 42a and 42b.
is made of a plate bent substantially perpendicularly to a flat intermediate portion 42c, and the intermediate portion 42c and the lower end portion 42
A long hole 44 is provided at the corner formed by b. The width d of the elongated hole 44 is defined to be slightly larger than the outer diameter of the elongated hole 44 in order to pass the hanging bolt 10 through the elongated hole 44. On the other hand, on the outside of the upwardly bent portion 42a of the door connecting member 42, there is a bent pick-up piece 46 as shown in FIG. Fixed. This pick-up piece 46 is attached to the drive unit 20 at a portion extending perpendicularly to the upper end 42a of the door connecting member.
It has a mounting hole 48 for connecting through a chain (not shown) that transmits the power from the door to the door connecting member 42 fixed to the door body 14. In addition, in the specific example shown, as shown in FIG. A magnet 50 for actuating 28 is installed. The mounting position of the magnet is set so that the magnet 42 is approximately at the same height as the reed switch 28 when the door connecting member 42 is mounted on the upper end of the door body 14.

The door connecting member 42 is attached to the door body 14 using two nuts 12a and 12 screwed onto the hanging bolt 10 on the upper end surface of the door body 14.
This is accomplished by positioning the intermediate portion 42c of the door connecting member 42 between the holes 44 and 42b, inserting the hanging bolt 14 into the elongated hole 44, and tightening it with the upper and lower nuts 12a and 12b. At that time, it is necessary to position the central axis of the hanging bolt 10 at a position half the thickness of the door main body 14, so that the elongated hole 44 of the door connecting member 42 is located in the middle as shown in FIG. It is important that the distance l from the bending point at the boundary between the portion 42c and the lower end portion 42b to the center of the semicircle, which is slightly larger than the hanging bolt 10, is formed to be equal to half the thickness of the door body 14. .

The door connecting member 42 attached to the door main body 14
is drivingly connected to a drive unit 20 for driving the door body 14 in the opening/closing direction by a power transmission member such as a chain or belt connected thereto. In the illustrated example, the drive unit 20 has a sprocket 52 for moving a chain (not shown) as shown in FIG. It is equipped with a reduction gear mechanism and a motor as a drive source. This drive unit 20 is fixed to the mounting bracket 4 by the above-mentioned connecting piece 18, so that the mounting parts 24a and 2 of the connecting piece 18 are provided on the side of the casing.
Bolts 22a and 22 protrude laterally from 4b
Bolt mounting portions 54a and 54b are provided for fixing the drive unit 20 to the connecting piece 18 by inserting the bolts 23a and 23b, respectively, and tightening the nuts 23a and 23b screwed onto each bolt.

As described above, when automating an existing manual door device, the connecting piece 18 is attached to the mounting bracket 4.
The drive unit 20 and the necessary reed switch 28 for detecting the door position are attached to the upper end of the door body 14 using a hanging bolt 10 and two nuts 12a and 12b screwed thereto. All that is required is the additional work of attaching the door connecting member 42, connecting the power transmission member from the drive unit 20 to this door connecting member, and attaching the magnet for operating the reed switch, and there is no need to replace the existing door device. Door automation can be realized extremely easily and economically. Also, especially
There is no need to perform any processing on the door body 14 side.

Further, the mounting bracket 4 and the connecting piece 18 are connected by using a mounting bracket having threaded holes for screwing the setscrews 38 and 40 in predetermined positions in consideration of automation, as in the above specific example. In case No. 4, this can be achieved by simply pressing the pressing pieces 34 and 36 with set screws, which is very efficient. On the other hand, if automation is not required, there is no need to prepare a manual door device again, and the mounting bracket can be used as a manual door by simply removing automation elements such as the drive unit, making it extremely versatile. .

In the illustrated example, a magnet is used as a reed switch to detect the position of the door body, but instead of this, the number of rotations of the motor of the drive unit is detected to control the opening and closing of the door body. Good too. In summary, according to the present invention, in a hanging sliding door, a minimum number of elements are added to the existing manual door device, and a screw hole for tightening the pressing piece is provided in the mounting bracket. Door automation can be easily achieved without any other processing. Furthermore, assembly and removal operations can be easily performed.

From the above, it is possible to obtain a manual door as is without adding the minimum elements for automation, and in the end, according to the present invention, both automatic and manual doors can be provided extremely easily and at low cost. It has the effect of being able to.
