[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric partitioning device which automatically partitions a room, and more particularly to a partitioning panel which is suspended and travels along a suspension rail fixed to a ceiling. To the structure of a self-propelled runner.

[0002]

2. Description of the Related Art The present applicant has already applied for a patent for this kind of electric partitioning device (Japanese Patent Application No. 3-155947). The essential points will be described with reference to FIGS.

[0003] The upper piece (2a) and the side piece (2b) are fixed to the ceiling (1).
Tubular suspension rail formed by the base and the bottom piece (2c)
(2) Within the two runners Tsu支with支杆suspended near both side ends of one partition panel (3) (4) (5), is disposed so as to be traveling I have.

Each runner (5) is connected to a bottom piece (2) of a suspension support rail (2).
a horizontal substrate which upper end is connected in suspended to penetrations a central groove (6) facing the longitudinal drilled in c)支杆(4) (7), standing from both sides of the substrate (7) A pair of left and right side plates (8),
Front plate erected from the front and back of the board (7) ( not shown)
And the rear plate (9), side plates (8), the front plate and the rear plate hollow box-shaped runner housing consisting anchored cover plate to the upper end (10) (9) (1
1) is provided.

Forward / reverse rotatable motor with built-in reduction mechanism
(12) is supported substantially horizontally by the left and right side plates (8), and a large-diameter drive wheel (13) is firmly fitted to the rotating shaft (12a) of the motor (12) projecting rightward in FIG. Have been.

[0006] the right side of the runner body (11), in this way, the driving wheel of a large diameter (13) is only one arranged substantially in the center
However, at the bottom of the left side of the runner housing (11), the drive wheels (1
3) A pair of front and rear driven wheels (14) having a smaller diameter are pivotally supported with a shaft (15) facing left and right , and a driving wheel (13) and a driven wheel (14) are provided.
Is in contact with the bottom piece (2c) of the suspension rail (2).

A power supply control device (16) is provided on the upper surface of the cover plate (10), and a current collecting brush (17) protruding from the side of the power supply control device (16) is connected to a suspension rail ( and sliding longitudinally <br/> stretched the feed line to the side inner surface of 1) (18), are as to power the motor (12).

Power is supplied to the motor (12) by the power supply control device (16) to rotate the drive wheel (13) forward and reverse, and the drive wheel (13) and the driven wheel (14) are suspended from the suspension rail (2). By rolling along the upper surface of the bottom piece (2c), the runner (5) can be moved to move the partition panel (3) along the suspension rail (2).

[0009]

However , in the conventional structure as described above, the rotating shaft (12) of the motor (12) is not used.
If the load of the partition panel (3) is directly applied to a) and the rotation of the motor (12) is not smooth, or if the partition panel (3) is large and heavy, the rotation of the motor (12) The shaft (12a) may be broken.

In view of the above problems, the present invention prevents the load of the partition panel from being directly applied to the rotating shaft of the motor, thereby smoothing the operation of the motor and possibly causing breakage of the rotating shaft of the motor. The goal is to eliminate.

[0011]

In order to achieve the above-mentioned object, the present invention provides a partitioning device on a suspension support rail fixed to a ceiling.
A drive that fits a runner that suspends the tunnel and is attached to the runner
Connect the wheel to the rotating shaft of the motor
Rotate the drive wheels with the motor to move the runner along the suspension rails.
In the electric partitioning device,
A large-diameter annular recess coaxial with one side of the drive wheel
And a cylindrical shaft at the center,
The shaft hole in the shaft part cannot rotate with the rotation shaft of the motor.
And the outer periphery of the cylindrical shaft is attached to the side of the runner body.
It is characterized in that it is pivotally supported via a bearing into a more protruding shaft cylinder .

[0012]

The shaft portion of the drive wheel is supported by the shaft tube fixed to one side surface of the runner body. Therefore, most of the load of the partition panel applied to the drive wheel is received by the shaft tube, and the rotating shaft of the motor has:
Since the load on the partition panel is hardly applied as a bending force , the rotational force of the motor can be smoothly transmitted to the drive wheels, and the possibility of breakage of the rotary shaft of the motor can be eliminated.

Next , an embodiment of the present invention will be described with reference to FIGS. Note that the same members as the conventional example described above, the detailed description are denoted by the same reference numerals will be omitted, will be described in detail only characteristic parts of this embodiment.

In this embodiment, a large-diameter annular recess (21) is formed on one side of the drive wheel (20) so as to be coaxial with the drive wheel (20).
And setting the center of the annular recess (21), a cylindrical shaft portion (20a)
Only, the side plates of the shaft portion (20a), the right side of the runner housing (11)
The outer surface (8), the barrel which is fixed via a flange (22a)
It is pivotally supported by a ball bearing (23) in (22) so that the bearing portion is located in the annular recess (21).

The rotating shaft (12a) of the motor (12) is
The shaft (20a) is fitted into the shaft hole (20a) of the
2a) and the shaft portion (20a) are prevented from rotating by the key (24).

[0016] (25), the inner side of the side plate of the right in the runner housing (11) (8), arranged in parallel with the side plate (8), the motor (1
This is a motor support plate that supports the right end of 2). Motor (12)
Is supported by a left side plate, as in the prior art.

In this embodiment, by adopting such a configuration, most of the load of the partition panel (3) applied to the shaft portion (20a) of the drive wheel (20) is reduced to the ball bearing (23).
Received by the shaft tube (22) via a rotation shaft of the motor (12)
Almost have it act as bending forces (12a).

Therefore, the rotation of the rotating shaft (12a) of the motor (12) does not become smooth, and most of the rotating force of the rotating shaft (12a) is transmitted via the key (24) to the driving wheel (20). the transmission as a thrust, the running speed of the partition panel (3) is not lowered. The bend rotation axis (12a) is a risk or to breakage yet greens.

Further, an annular recess (21) is provided in the drive wheel (20), and the shaft of the drive wheel (20) is supported in the annular recess (21). In addition, the overall length from the left end of the motor (12) to the outer end of the drive wheel (20) can be reduced, and the size of the runner (5) can be reduced.

[0020]

[Effects of the Invention] The present invention has the following effects. (A) Since the weight of the partition panel does not directly act on the rotating shaft of the motor, no bending force is generated on the rotating shaft of the motor, so that the motor can be operated smoothly and the rotating shaft of the motor can be operated. Can be prevented from being bent or broken. (B) within the annular recess of the drive wheel, pivotally the shaft portion of the drive wheel to the shaft tube
Since was supported, can be made close to that amount drive wheels to the motor, the runner itself Ru can be miniaturized.
