  The present invention relates to a footwear rotating device, and more particularly to a footwear rotating device that rotates 180 degrees so that a subsequent user can easily wear it after, for example, a user uses and removes footwear such as slippers and indoor footwear. Is.

  For example, at the entrance and exit of a toilet, it is often the case that a slipper for a toilet installed in advance is replaced with a slipper used outside the toilet.

  In such a case, the slipper used in the toilet is usually removed by the previous user with its tip side (toe side) facing away from the toilet. The operation of the slipper must be changed by operation, or the user must wear the slipper by inverting his / her body.

  In order to solve such inconvenience, various footwear rotating apparatuses configured to automatically rotate the direction of footwear such as slippers by 180 degrees have been proposed.

  In Patent Document 1, a rotary table on which footwear that is rotatably incorporated in a box-shaped body is combined with a load sensor that detects a load acting on the rotary table, and a detection signal of the load sensor is obtained. There has been proposed a rotary footwear table configured to automatically reverse the direction of footwear on a rotary table by 180 degrees.

  In Patent Document 2, a motor is attached to a rotary table on which footwear incorporated so as to be rotatable with respect to a box-shaped main body, a rotation sensor for detecting the rotation position of the rotary table, and a load acting on the rotary table are detected. There has been proposed a rotary footwear table that is provided with a heavy load sensor and a light load sensor that automatically rotate the direction of the footwear on the rotary table by 180 degrees based on detection signals of these sensors.

  Patent Document 3 proposes a footwear turntable provided with a turntable that can be moved up and down and rotated on a base, and further equipped with automatic rotation means for automatically rotating the turntable by 180 degrees.

However, in any of Patent Documents 1 to 3 described above, the rotary table is not the same surface as the floor surface where these devices are installed, and has a step with respect to the floor surface (from the floor surface). This is inconvenient when, for example, a person with weak legs wears the footwear and puts it on the rotary table, or takes off the footwear and gets off the rotary table.

  Next, the connection configuration of each circuit component and the motor 15 described above will be described in detail with reference to the sequence control circuit diagram shown in FIG.

  In this sequence control circuit, for example, a fuse 32 is connected in series and a capacitor 33 is connected in parallel to a power supply mount 31 for introducing AC 100V power.

  A power switch 30 is connected in series to the power supply mount 31, and a contact LS1 of the first switch 34, a contact LS2 of the second switch 36, and a series circuit of the electromagnetic relay 35 are connected in parallel. Further, the contact RYS1 of the electromagnetic relay 35 is connected in parallel to the contact LS1 to constitute a self-holding circuit.

  Furthermore, the contact RYS2 of the electromagnetic relay 35 and the motor 15 are connected in parallel to the power supply mount 31.

  Next, the operation of the footwear rotating apparatus 1 having the above-described configuration will be described with reference to FIG.

In a state where the power switch 30 is turned on, when a user wearing slippers 100 on both feet is placed on the footwear placement table 4 in the footwear rotation device 1, the footwear placement is performed by the load (weight) of the user. The table 4 has its three stop pins 4a sliding down in the three receiving holes 22 provided in the outer rotating body 17 and vertically descending, and the lower surface is in contact with the four spacers 14 in total. Stop.
At this time, the lower surface of the footwear placing table 4 operates the first switch 34 to close (turn on) the contact LS1. As a result, the electromagnetic relay 35 is energized from the AC100V power source via the contacts LS1 and LS2, and the electromagnetic relay 35 is excited to close (turn on) the contacts RYS1 and RYS2. When the contact RYS1 is closed, a self-holding circuit is formed in a series circuit including the electromagnetic relay 35.

  When the contact RYS2 of the electromagnetic relay 35 is closed, a voltage is applied from the AC 100V power source to the motor 15, and the motor 15 is started. As a result, only the inner rotating body 16 rotates. At this time, since the load (weight) by the user is applied to the footwear placing table 4 and the outer rotating body 17, the clutch means 18 is in a disconnected state, and the footwear placing table 4 and the outer rotating body 17 do not rotate.

  By the above operation, the outer rotating body 17 and the footwear placement table 4 are not linked to the inner rotating body 16, and only the inner rotating body 16 is rotated by the motor 15.

  Next, when the user removes the slipper 100 from both feet and leaves the footwear placement table 4 (load release), the footwear placement table 4 is lifted vertically upward by the three levitation springs 23, thereby The first switch 34 is activated to open (turn off) the contact LS1. Even if the contact LS1 is opened, since the self-holding circuit is formed in the series circuit including the electromagnetic relay 35, the electromagnetic relay 35 is not demagnetized, and thus the motor 15 continues to rotate.

  With the above operation, the footwear placement table 4 is rotationally driven by the motor 15 in the direction of the arrow shown in FIG.

  Eventually, when the rotation angle of the footwear placement table 4 reaches approximately 180 degrees from the initial position, the stop pin 4b of the footwear placement table 4 engages with the free end of the spring piece 37, and this spring piece 37 Is bent once in a bow shape and detached from the spring piece 37 by further rotation of the footwear placing table 4.

  When the stop pin 4b is disengaged from the spring piece 37, the spring piece 37 is suddenly displaced by its own spring force, abuts against the switch operating piece 36a of the second switch 36, and the contact of the second switch 36. LS2 opens (turns off). When the contact LS2 is opened, the electromagnetic relay 35 is deenergized and demagnetized to open the contacts RYS1 and RYS2. When the contact RYS2 is opened, the motor 15 is deenergized, whereby the motor 15 stops.

  By the above operation, the footwear placement table 4, and thus the slipper 100 thereon, is stopped at the position shown in the lower column of FIG. 9 rotated 180 degrees in the direction of the arrow from the initial position shown in the upper column of FIG. It is possible to make it easy for a person to wear.

  In addition, since the upper surface of the footwear placement table 4 is arranged in the same or substantially the same surface as the surrounding floor surface, it can be used without any danger even when used by a person with weak legs. And can easily respond to barrier-free requests in recent housing and the like.

  The present invention can be applied to a variety of footwear such as sandals, indoor shoes, sports shoes, leather shoes, etc. It can be installed on a floor of a part, a floor of a self-explanatory for entering and exiting outside the kitchen, and a wide range of applications are possible.
