Description

  The present invention relates to a walking training apparatus that trains a pedestrian to walk at an arbitrary speed.

  As part of improving production efficiency in factories, there are attempts to train workers to walk so that they can move to work places while maintaining an appropriate walking speed. The walking training apparatus shown in Patent Document 1 is used for such walking training, which will be described below.

  A conventional walking training apparatus includes a sensor that generates a walking start signal disposed at one end of a walking area, a plurality of lamps arranged at equal intervals in the walking area, and a control unit that can sequentially turn on the plurality of lamps. And means for determining the lighting interval of the lamp in accordance with the ideal walking time, and the sensor outputs a walking start signal so that the predetermined number of lamps on the sensor side are sequentially determined according to the lighting interval. And a means for outputting a command to turn on the lamp. Next, the operation of the conventional walking training apparatus will be described. First, the sensor detects a pedestrian walking in the walking area and outputs a walking start signal, and the walking start signal is input to the control means. Thereafter, the control means turns on the adjacent lamps in order from the sensor-side lamp at predetermined time intervals. Therefore, the pedestrian can determine whether his / her walking speed is an ideal walking speed by checking the lamps that are sequentially turned on.

JP-A-2005-348836

  Since the conventional walking training apparatus sequentially turns on the lamps from the sensor side, there is a problem that walking training cannot be performed in which a plurality of pedestrians walk in opposite directions at the same time. In order to solve this problem, it is conceivable to install a sensor and a plurality of lamps for each walking direction. However, this increases the number of sensors and lamps by the number of walking directions, which increases the manufacturing cost. In addition, there is a problem that the control for sequentially lighting the lamps in each walking direction becomes complicated.

  This invention was created in view of the said subject, and even if it is a case where a some operator walks in the direction which opposes simultaneously, it aims at provision of the walking training apparatus which can perform both walking training simultaneously. In order to achieve this object, the present invention provides a rotary drive source that can rotate at an arbitrary speed, a rotatable drive pulley that is connected to the output shaft of the rotary drive source, and an opposing position of the drive pulley. An endless circulating and moving member that is circulated and fed by the operation of the rotary drive source in a walking training apparatus comprising a driven pulley that is freely rotatable and an endless circulating and moving member that is wound around the driven pulley and the driving pulley. It is characterized in that a plurality of marks are attached to.

  In addition, you may enable the drive of a rotational drive source based on the sensor arrange | positioned in the position which a pedestrian can detect, and the detection signal output from this sensor. Further, bevel gears may be arranged on the output shaft of the rotational drive source and the drive pulley, respectively, and the rotation of the output shaft may be transmitted to the drive pulley by engagement of these bevel gears.

  According to the walking training apparatus of the present invention, since the endless circulation moving member is sequentially fed at a predetermined speed, even when a plurality of pedestrians walk simultaneously in opposite directions, there is an advantage that both walking training can be performed simultaneously. is there. In addition, since the endless circulation moving member is marked, the conventional lamp and the control for sequentially lighting the lamp are unnecessary, and the configuration of the apparatus is relatively simple compared to the conventional one, so that the manufacturing cost is low. There is also an advantage that can be greatly reduced.

It is a schematic explanatory drawing of the walking training apparatus of one Example concerning this invention. It is principal part schematic explanatory drawing of another Example concerning this invention.

  First, the walking training apparatus of the present invention will be described below with reference to FIG. The walking training apparatus 1 of the present invention includes a motor 4 that is an example of a rotational drive source, a disk-shaped drive pulley 5 that is rotatably arranged integrally with an output shaft 4 a of the motor 4, and the drive pulley 5. A driven pulley 7 having the same dimensions and rotatably arranged, and a belt 2 which is an example of an endless circulation moving member wound around the driven pulley 7 and the driving pulley 5 are provided.

  The motor 4 is fixed to a mounting plate 6 having an L-shaped cross section, and the mounting plate 6 is fixed to the upper surface of a gantry 11a made of an iron member. The gantry 11a is composed of a leg assembled by welding using a plurality of iron members having a cross-sectional "<" shape and a base plate made of an iron plate, and the base plate is welded to the upper end of the leg. The upper surface of the base plate is substantially horizontal with respect to the floor surface. That is, the motor 4 is arranged so that a part of the output shaft 4a protrudes from the mounting plate 6 and the axis of the output shaft 4a is substantially horizontal with respect to the floor surface.

  The drive pulley 5 and the driven pulley 7 are each composed of an iron disk, and grooves 5a and 7a having a “U” -shaped cross section are formed over the outer periphery of these disks. Further, the center of the drive pulley 5 and the driven pulley 7 is bored, and these holes are provided on the output shaft 4a in the case of the drive pulley 5 and on the shaft described later in the case of the driven pulley 7. 14 are formed with dimensions that allow them to be inserted. Further, since the screw holes are formed in the inner diameters of these holes from the outer periphery to the inner diameter, the driving pulley 5 and the output shaft 4a or the driven pulley 7 and the shaft 14 are respectively fixed by screws and integrated. Can rotate. The shaft 14 protrudes from both side surfaces of the driven pulley 7, and the driven pulley 7 is rotatably supported by support bases 8 and 8 that support these protruding portions. The support bases 8 are fixed to the upper surface of a base 11b having the same structure as the base 11a, and the axis of the driven pulley 7 is substantially horizontal with respect to the floor surface.

  The belt 2 is formed of a single resin material having a round cross section at both end faces and having a slight elasticity, and is provided with a plurality of marks 2a at a predetermined size and interval. They are joined to each other by heat treatment or the like to form an endless member. The belt 2 is wound around grooves 5 a and 7 a of the drive pulley 5 and the driven pulley 7, and the distance between the shafts of the drive pulley 5 and the driven pulley 7 is a distance at which a constant tension is generated in the belt 2. Is set. That is, between the shafts of the drive pulley 5 and the driven pulley 7, two straight portions that are parallel in the vertical direction appear by the belt 2.

  On the other hand, iron covers 9 and 9 are respectively fixed to the upper surfaces of the gantry 11a and 11b, and these covers 9 and 9 are positioned so as not to interfere with the belt 2 wound around the drive pulley 5 and the driven pulley 7. Each notch is provided. In addition, since the transparent cover 3 is fixed to the covers 9 and 9 so as to cover the two straight portions of the belt 2 described above, a pedestrian (see FIG. (Not shown).

  In addition, sensors 30a and 30b capable of emitting optical axes 31a and 31b extending in a direction orthogonal to the extending direction of the belt 2 are fixed to the side surfaces of the mounts 11a and 11b. When the optical axes 31a and 31b are interrupted by a pedestrian walking in a path 12 that is substantially parallel to the path 12, detection signals are output from the sensors 30a and 30b.

  On the other hand, a control device 20 is fixed to the side surface of the gantry 11a and the surface facing the sensor 30a. On the front surface of the control device 20, a volume 21 capable of changing the rotation speed of the output shaft 4a, An emergency stop switch 22 capable of outputting a stop command to the motor 4 is provided. The volume 21 can adjust the rotation speed of the output shaft 4a, while the emergency stop switch 22 can be pressed to stop the rotation of the output shaft 4a.

  Next, the operation of the walking training apparatus 1 according to the present invention will be described. When a pedestrian walking in the passage 12 walks from the motor side to the driven pulley side, the optical axis 31a is blocked by the pedestrian, so the sensor 30a outputs a detection signal to the control device 20. To do. In response to this, the control device 20 gives a rotation command to the motor 4 based on the speed set by the volume 21. Due to this rotation command, the drive pulley 5 rotates clockwise at a predetermined speed, so that the belt 2 is circulated and fed by contact resistance with the groove 5a, and the driven pulley 7 also rotates. That is, since the belt 2 is fed from the drive pulley side to the driven pulley side if the lower straight portion described above, the mark 4a moves in the feed direction 10a, while the belt 2 is moved from the driven pulley side if it is the upper straight portion. Since it is sent to the drive pulley side, the mark 4a moves in the feed direction 10b. Thereafter, since the optical axis 31b is blocked by the pedestrian, the sensor 30b outputs a detection signal to the control device 20. Thereby, the control device 20 gives a rotation stop command to the motor 4 to stop the circulation feed of the belt 2.

  As described above, according to the walking training apparatus 1 of the present invention, since the pedestrian can see the mark 2a moving in the same direction as his / her own walking direction, is his / her walking speed an appropriate speed? You can walk while checking. Further, since the feeding directions 10a and 10b of the mark 2a can obtain two directions by one operation, there is an advantage that walking training in opposite directions can be performed simultaneously. Further, since the belt 2 is marked with a mark 2a, the conventional lamp and the lighting control of the lamp are not necessary, and the apparatus configuration is relatively simple as compared with the conventional one. There is also an advantage that can be greatly reduced.

  In the embodiment, the drive pulley 5 is directly attached to the output shaft 4a of the motor 4. However, as shown in FIG. 2, the bevel gears 15 and 15 are fixed to the output shaft 4a and the drive pulley 5, respectively. The drive pulley 5 is preferably arranged so that the axes thereof are orthogonal. This also has the advantage that the walking training apparatus 1 can be reduced in size because the protruding direction of the motor 4 can be changed from horizontal to vertical. Further, the gear ratio of the bevel gears 15 and 15 may be changed in accordance with the maximum output torque or the maximum output rotation speed of the rotation drive source. Moreover, although the magnitude | size of the drive pulley 5 and the driven pulley 7 was made into the same dimension, it cannot be overemphasized that each magnitude relationship may be changed as needed. On the other hand, although the operation control of the motor 4 is performed based on the detection signals of the two sensors 30a and 30b, the operation of the motor 4 is started by the detection signal of one sensor, and the operation is stopped after a predetermined time has elapsed from the start of the operation. Thus, timer control may be used. Furthermore, although the cross-sectional shape of the grooves 5a and 7a is a “U” shape, it may be changed to a shape with good rotation transmission efficiency in accordance with the contact resistance of the belt 2 and the grooves 5a and 7a. On the other hand, although the endless circulation moving member is the belt 2, for example, a toothed belt or a transmission roller chain may be used. In this case, the drive pulley 5 and the driven pulley 7 are connected to the endless circulation movement member. Needless to say, it may be changed to a toothed pulley or a sprocket that can be reliably engaged.
