Description

The present invention relates to an electric footwear changing device that changes the direction of footwear by 180 degrees.

  There are many scenes where people change their shoes in daily life. For example, there are many scenes in which footwear is changed in daily life, such as indoor to outdoor, outdoor to indoor, and indoor movement. At this time, the direction of the footwear is often opposite to the direction of travel, and in this case, the movement associated with reversing the direction of the footwear is the behavior of elderly people, care recipients, and healthy people when both hands cannot be used. It obstructs the flow and is accompanied by physical pain.

Japanese Patent Application Laid-Open No. 2005-224296 discloses a technique for detecting that a person is on the turntable and rotating the turntable 180 degrees after a certain time when the weight is removed.

Japanese Utility Model Laid-Open No. 6-70681 discloses a technique of automatically rotating the direction of the footwear by 180 ° after a predetermined time after the footwear is taken off on the turntable.

Japanese Utility Model Laid-Open No. 7-34780 discloses a technique for rotating the removed footwear by 180 ° within 5 seconds.

Utility Model Registration No. 3071420 discloses a technique for rotating a turntable by 180 ° via a drive system by the elasticity of a spring using the weight of a human.

    These prior arts add a mechanism to rotate the turntable and automatically rotate the footwear by changing the direction of the footwear using a timer or by detecting the weight, etc. Any voluntary operation is not taken. It is an object of the present invention to provide an electric footwear changing device that can change the direction of footwear as needed according to the user's will.

  This device has a disk-shaped turntable installed on the upper plane of the housing with almost no steps, a motor for driving the turntable, a reduction gear box for reducing the rotation of the motor, a rotation end detection microswitch, The battery comprises a battery for driving the motor, a battery holder, and a turntable rotation instruction switch. With this configuration, there are many scenes where you can change footwear in daily life, such as moving from indoor to outdoor, from outdoor to indoor, and indoors, but you can freely change the direction of the footwear by 180 degrees depending on the user's will. In addition to eliminating inconvenient movements that are physically painful and not using a commercial power supply, it is convenient to carry around anywhere.

  This device is safer by the will of the user because it obstructs the flow of behavior and prevents inconvenient movements that cause physical distress, such as when elderly people with reduced physical function, care recipients, and healthy people cannot use both hands. It is convenient for carrying around.

FIG. 1 is a plan perspective view of this apparatus, and FIG. 2 is a sectional view of a partially cut side surface of this apparatus. In FIG. 1, a box-shaped housing 1 that accommodates the turntable 2 and the drive unit 13 is provided, and a circular hole that can accommodate the turntable 2 is provided on the upper surface, and the turntable 2 is fitted into this hole. The turntable 2 is placed under the turntable 2 so as to be smoothly rotated by being placed between the turntable 2 and the turntable holding base 2-1 via a ball 8. FIG. 2 is a partial cross-sectional view of the internal structure of the apparatus. A motor as a drive unit and a gear box 11 are installed, and a gear reduction mechanism with a high reduction ratio is configured by a gear built in the gear box 11. Inadvertent rotation of the turntable 2 due to external force is prevented.

An output shaft 13 via a gear box 11 is arranged on a vertical line of the rotation center shaft 13 of the turntable 2, and a turntable rotation drive bar 5 and a power source polarity switching bar 12 are installed on the output shaft 13.

The turntable rotation drive bar 5 includes a microswitch operation terminal 4 with a turntable rotation end detection lever of the turntable, detects the rotation end (180 °) of the turntable, pushes the lever of the rotation end detection microswitch 6 and cuts off the power supply. .

A power supply polarity reversal switching bar 12 is installed on the opposite side of the drive mechanism operating rotary shaft 13 where the turntable rotary drive bar 5 is installed, and the lever of the toggle switch 9 is interlocked with the power cutoff of the rotation end detection microswitch 6. To reverse the polarity of the power supply.

By pressing the turntable rotation operation switch 16 for reversing the direction of the footwear, the substrate 16-6 is deformed (see FIG. 4 (B)) and the conductive thin film copper foil 16-5 is energized to cut off the power supply. By turning on the micro switch 6 that is on, the turntable 2 on which the footwear is mounted is rotated 180 °, the rotation end detection micro switch 6 is turned off and the power is cut off and stopped.

The outline of the circuit will be described below with reference to FIG.
This circuit includes a motor 11 for driving the turntable 2, a power source 18, a power polarity reversing circuit 19, a rotation end detection circuit 20, a turn table rotation instruction circuit 21 (see 16 in FIG. 1), and the like. ing.
When changing the footwear, when the turntable rotation operation instruction switch 16 is pressed, the turntable rotation end detection microswitch 6 is turned off and the turntable 2 starts rotating. When the turntable rotates 180 °, the rotation end detection microswitch 6 is installed at the turntable rotation drive bar 5 and the rotation end detection switch operation terminal 4 pushes down the lever of the rotation end detection microswitch 6 to cut off the power supply. The power polarity reversing toggle switch operating bar 12 operates the lever of the polarity reversing toggle switch 9 to reverse the polarity of the power source, reverses the direction of rotation of the motor and stops, enters into the preparation for the next rotation and waits for the next instruction. . By repeating this operation, it becomes possible to always respond to the user's instruction as necessary, and the turntable rotation operation instruction switch 16 needs to consider which side of the rotation end detection microswitch 6 is OFF. There is no operation.
