Description of the Invention (i) [Technical Field] The present invention relates to an elevator door device. (Please read the precautions on the back before filling out this page.) [Background] In the case of automatic doors at the entrances and exits of general buildings and two centrally opened portals, the driven doors are usually two and the quality is mostly About 50 ~ 7 0kg. On the other hand, in the elevator door device, even for the same two centrally opened portals, it is necessary to operate the door on the trunk side and the door on the passenger side, and the equipment is required to be higher than the automatic door Safety, so the quality of the driven door is more than 100 times to 400 kg of automatic door. And compared with automatic doors installed between the house and the building, the elevator door system installed in the building is required to have higher quietness, so the gearless motor with a lower noise than the gear motor generally used in electric doors is The torque required by the motor becomes larger, which is larger than the automatic door. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Because the automatic door system must be controlled below the height of the ceiling for the up and down direction, the size is strictly limited, but in the direction orthogonal to the plane along the door surface, there are Obstacles are rare, and size restrictions are not as described above. Generally, automatic doors are less restrictive than elevator door devices in terms of size due to the small size of the motor and the direction orthogonal to the plane along the door surface. Therefore, the motor has a rotation axis arranged in a direction slightly orthogonal to the plane along the door surface, and it is easy to set the length of this rotation axis to be narrower than the width of the automatic device, and it is generally performed. This & Zhang scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) ~ '-4- 579364 A7 B7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) On the other hand, The door device is based on the above-mentioned reasons, the motor is large, and the elevator door device is generally installed on the car. Therefore, for the plane along the door surface, there is a side door device in the boarding direction in an approximately orthogonal direction. In order to avoid contact with these parts during the travel of the elevator, the plane along the surface of the door is strictly restricted in size to approximately orthogonal dimensions (about 90 legs in the two doors that open in the center). In this regard, since the device is arranged at a position higher than the top of the car, the size restriction in the up-down direction is not strict compared with the electric door, and most of the allowance is more than 300 legs higher than the height of the entrance and exit. The characteristics of the motor of the door device and the characteristics of the installation conditions are such that when an electric motor is installed between the end of the boarding side of the trunk side of the trunk and the side of the trunk side of the rail frame, the rotary shaft is arranged approximately vertical. Japanese Unexamined Patent Publication No. 8-2 0 8 1 5 9 is known as a conventional elevator door device in which a rotating shaft is arranged vertically, as shown in FIG. 7. The elevator car doors 1 2 and 1 3 are attached to the upper part of the elevator, and door hooks 6 and 7 having rotatable rollers 8 to 11 are respectively installed, and the rollers 8 to 11 of each door hook 6 and 7 are fixed along The door rail 14 of the rail frame 5 can travel horizontally, and the door sliding feet 15 to 18 are installed under the trunk doors 1 2, 1 3, and the sliding feet 15 to 18 are along the bottom of the box. The plate 19 can be moved in a horizontal direction. At the left end portion of the guide rail frame 5, a door motor 1 is mounted on the rotation axis of the drive pulley 2. On the right end portion of the guide rail frame 5, a driven pulley 3 is disposed opposite the drive pulley 2. In the drive pulley 2 --------- 1¾ clothing ------ 1T ------- ^ (Please read the precautions on the back before filling this page) This paper size applies to Chinese national standards (CNS) A4 specification (210X29 * 7 mm) -5- 579364 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (3) The rotation transformation of the door motor 1 is wound between the driven pulley 3 The door belt 4 which moves linearly is connected between the door belt 4 and the door hooks 6 and 7 by brackets 20 and 21 respectively. Therefore, the rotation system of the door motor 1 is transformed into rotation on the horizontal plane of the door belt 4 between the driving pulley 2 and the driven pulley 3, and the car case connected to the door belt 4 is opened / closed by the brackets 20, 21. Doors 1 2, 1 3. Here, the door motor 1 is made long in the axial direction of the shaft rotation shaft and has a small diameter, and the rotation shaft is arranged substantially perpendicularly. However, in the conventional door device for an elevator, since the door motor 1 must be disposed within a wide width of the guide rail frame 5 in the direction of entry and exit of the car door 1 2, 1 3, once it is installed on the rotary shaft of the door motor 1 The diameter of the driving pulley 2 is designed to be within the wide width of the guide rail frame 5. Then, the diameter of the driving pulley 2 is restricted, so that the life span of the door belt 4 which greatly changes as the portion of the driving pulley 2 rotates with a small radius of curvature is reduced. , Or the mass of the driveable car door 1 2, 1 3 is limited. Moreover, when a reduction gear is installed in an elevator door device, it is impossible to increase the reduction ratio when the reduction pulley is controlled within the width of the guide rail frame 5. The quality of the car door 1 2 1 3 is related to the torque of the motor. Is limited. Therefore, in restaurants, etc., it is desired to increase the height of the car door 1, 2 or 3, or to attach decorative panels on the surface to improve the aesthetics and creativity, but this cannot be implemented. An object of the present invention is to provide an elevator door device that can increase the life span of a door belt without increasing the width of a guide rail frame and can handle an increase in the mass of a car door. [Disclosure of Invention] (Please read the notes on the back before filling out this page) The paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) -6-579364 A7 ___ B7 V. Description of the invention (4) ( (Please read the precautions on the back before filling out this page) The present invention is to achieve the above-mentioned purpose, which includes: a trunk door; an upper door guide that guides the trunk door; and the door guide is fixed and fixed on the trunk. A guide rail; a pad that guides the lower part of the car door; a door motor that is disposed in a region from the end of the boarding place side of the pad to the car side of the rail frame and drives the car door A drive pulley provided on the door motor; a driven pulley disposed opposite the drive pulley; an elevator door device wound around the drive pulley and the driven pulley and a door belt to which the aforementioned car door is installed, which is characterized by: The door motor is provided with a rotation axis disposed substantially orthogonal to a plane along the surface of the trunk door, and the length of the rotation axis is set to be longer than the boarding place of the pad. Trunk-side end portion to the end portion of the guide block until the short distance. The door device for an elevator of the present invention is a door motor having a rotation axis arranged substantially orthogonal to a plane along a surface of a car door, and the length of the rotation axis is set to be longer than a boarding place. The distance from the side end to the side of the rail frame is short, without increasing the width of the rail frame, which can increase the radius of curvature of the door belt, so it can improve its service life and handle the quality of the car door Increase. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the aforementioned conventional technology, the volume of the motor is long in the axial direction. However, the motor of the elevator door device of the present invention has the feature of increasing the diameter. Because the torque of a motor generally relies on the surface area of a magnet, it can increase torque more efficiently than extending in the axial direction and extending in the diameter direction. Therefore, the present invention can increase the torque more efficiently than the prior art . At this time, because the motor of the elevator door device requires torque, so two centrally opened doors are taken as an example. The diameter of the motor is the size of the paper of the motor. The Chinese national standard (CNS) A4 specification (210X297 mm) is applied. -7- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 579364 A7 _B7___ V. Description of the invention (5) The length in the axial direction is about 2 to 3 times, which is about 200 to 300 mi. [Best Mode for Carrying Out the Invention] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a front view showing an elevator door device according to an embodiment of the present invention. The elevator car doors 1 2 and 1 3 are attached to the upper part of the elevator, and door hooks 6 and 7 having rotatable rollers 8 to 11 are respectively installed, and the rollers 8 to 11 of each door hook 6 and 7 are fixed along The door rail 14 of the rail frame 5 can travel horizontally, and the door sliding feet 15 to 18 are installed under the trunk doors 1 2, 1 3, and the sliding feet 15 to 18 are along the bottom of the box. The plate 19 can be moved in a horizontal direction. At the left end portion of the guide rail frame 5, a door motor 1 is mounted on the rotation axis of the drive pulley 2. On the right end portion of the guide rail frame 5, a driven pulley 3 is disposed opposite the drive pulley 2. Between the driving pulley 2 and the driven pulley 3, a door belt 4 that converts the rotation of the door motor 1 into a linear motion is wound. A bracket 20, 2 1 is connected between the door belt 4 and the door hooks 6, 7. Connected separately. The backing plate 19 and the trunk frame 5 are fixed to the trunk 22 supporting the elevator. Fig. 2 is a side view of the elevator door device shown in Fig. 1 as viewed from the right. The elevator door device is configured within a distance W from the end portion of the boarding place 19 to the end portion of the carriage side of the guide rail frame 5.

V. Description of the invention (6) The axis of rotation is generally orthogonal, and the length of this axis of rotation is set to be longer than the end from the side of the boarding place of the pad 19 to the guide rail. The distance W to the trunk-side end of the frame is short. The motor of the door device for an elevator having the above structure has a feature of increasing the diameter. Since the torque system of a motor generally relies on the surface area of a magnet, it can increase the torque more efficiently than extending in the axial direction. Therefore, the present invention increases the torque more efficiently. At this time, since the motor of the elevator door device requires torque, two centrally opened doors are taken as an example. For a motor shaft of about 90 legs, the motor diameter is 2 to 3 times the length in the direction of the motor shaft. It is about 200 ~ 300 mm. The above-mentioned elevator door device is in a plane along the surface of the car door 1, 2 or 3, or a plane parallel to it, and the drive pulley installed on the rotation axis of the door motor 1 rotates, and does not drive the pulley as in the past. The diameter of 2 can be determined without being directly limited by the width of the guide frame 5. Therefore, the same method can be applied to the roof height of the car 22, and the drive pulley 2 can be used to convey the necessary driving force according to the mass and acceleration / deceleration of the car door 1 2, 1 3. The diameter can be freely designed according to the height of the rail frame 5. Because the drive pulley 2 can be made to have a larger diameter than before, the door belt 4 formed by winding the drive pulley is rotated with a large radius of curvature, which will not reduce its service life as in the past. Or the quality of driveable car doors 1 2, 1 3 is limited. Therefore, it is possible to easily increase the height of the car door 1, 2 or 3, or to attach the decorative board on the surface.
