BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of closing a rotary door by protruding a rotor from the floor in a state where the rotary door is opened and buried in the floor so that the upper end is flush with the floor. The present invention relates to a rotating door open state holding device for stopping movement.

[0002]

2. Description of the Related Art As a conventional open state holding device for a rotary door of this type, a device configured as shown in FIGS. 6 to 10 is known.

[0003] A description will be given below of the conventional rotating door open state holding device. There are two states: a state in which the case 1 is pivotally supported by a horizontal shaft 2 and is accommodated in the case 1 and a state in which it projects upward from the case 1. The apparatus is provided with a substantially semicircular rotor 3 rotatable within a range of 180 degrees between the casings 1. The casing 1 is housed in the outer casing 4, and the rotating door open state holding device is embedded in a predetermined position on the floor 5. The rotor 3 is rotated so that the rotor 3 comes into contact with the outer surface of the lower end of the opened revolving door 6 when the revolving door 6 is to be opened, so that the revolving door 6 is moved upward from the case 1 and the floor 5 surface. It is designed to protrude.

[0004] More specifically, the rotor 3 is
The operation of rotating between the state in which the rotor 3 protrudes from the case 1 and the state in which the rotor 3 protrudes upward is performed by hand.
When it is rotated by 80 degrees and protruded upward from the case 1, the posture can be maintained. When the rotor 3 housed in the case 1 is projected from the case 1,
By pressing the lightened upper surface at the other end of the rotor 3 with a finger, one end of the rotor 3 protrudes upward from the case 1 and the portion is pinched by a finger to rotate the rotor 3.

[0005]

However, in the conventional rotating door open state holding device, the rotor 3
When the heel of the high heel is placed on the lightened upper surface on the other end side of the rotor 3 in a state where the heel of the high heel enters the case 1, the heel may be cut off, and There were problems such as spoiling.

SUMMARY OF THE INVENTION The present invention solves such a problem. In a state where the rotor is accommodated in the case, even if the heel of the high heel is placed on the upper surface on the other end side of the rotor, the heel of the high heel remains in the case. It is an object of the present invention to provide an apparatus for maintaining the open state of a rotary door with high security without entering.

[0007]

SUMMARY OF THE INVENTION To solve this problem, the present invention is directed to a state in which the upper end is buried in the floor so as to be flush with the floor surface and the revolving door is opened, and approximately halfway from the floor surface. A rotating door open state holding device in which a circular rotor is projected to stop the closing movement of the rotating door, and both ends of a substantially semicircular outer peripheral surface of the rotor are cut off to form a stepped portion. A lock member having a lower end pivotally supported by the horizontal shaft is provided in a case that is formed and accommodates the rotor pivotally supported by the horizontal shaft, and the lock member has a claw having one end or the other end of the rotor. When the rotor is biased by a spring in a direction of locking to the step on the side, the step on one end side of the rotor engages with a claw of a lock member provided in the case in a state where the rotor does not fit into the case and does not protrude. And the step on the other end of the rotor is The rotation of the rotor is stopped by being locked to a step formed on the inner surface of the upper end, and the step on the other end of the rotor is brought into contact with the claw of the lock member in a state where the rotor completely projects upward from the case. The gist of the present invention is an apparatus for holding an open state of a rotary door, which is configured so as to be locked and a step on one end side of the rotor abuts on an upper end of the case to stop rotation of the rotor.

[0008]

With this configuration, the claw of the lock member is locked to the step on one end when the rotor is housed in the case, so that even if the heel of high heels is placed on the upper surface on the other end of the rotor. Thus, it is possible to provide a highly safe rotating door open state holding device without the heel of the high heel getting into the case.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 5, reference numeral 11 denotes a case which is pivotally supported by a
This is a substantially semicircular rotor that is rotatable in a range of 180 degrees between a state accommodated in the case 12 and a state protruding upward from the case 12. Since the rotor 11 has one end side, which is the start end side of the rotor, made heavy, the rotor 11 can maintain its posture when it is rotated 180 degrees to project upward from the case 12. Also, both ends of the substantially semicircular outer peripheral surface of the rotor 11 are cut off with a small thickness to form steps 14 and 15.

In the case 12, the rotor 11 has a case.
A claw 16 is provided for engaging the step 14 on one end of the rotor 11 and the step 15 on the other end of the rotor 11 in a state where the rotor 11 is accommodated in the case 12 and a state where the rotor 11 is completely protruded from the case 12. A lock member 17 for stopping rotation is provided. The lower end of the lock member 17 is pivotally supported by a horizontal shaft 18, and the claw 16 is moved by a coil spring 19 interposed between the lock member 17 and the inner surface of the case 12.
It is urged in the direction of locking with the step portion 15. Accordingly, the claw 16 of the locking member 17 is locked to the step portion 14 on one end side in a state where the rotor 11 is accommodated in the case 12, and the other end in a state where the rotor 11 is completely protruded upward from the case 12. The pawl 16 of the lock member 17 is locked to the step 15 on the side so that each position is maintained unless the lock is released. Note that the rotor 11 is housed in the case 12 and the stepped portion on one end side.
In the state where the claw 16 of the lock member 17 is locked to the step 14, the step 15 on the other end side is locked to the step 20 on the inner surface of the upper end of the case 12. When the rotor 11 completely projects upward from the case 12 and the claw 16 of the lock member 17 is locked to the step 15 on the other end, the step 14 on one end contacts the upper end of the case 12.

With the case 12 housed in the outer case 21, the revolving door open state holding device is embedded at a predetermined position on the floor 22 and opened when the revolving door 23 is to be opened. The rotator 11 is rotated so that the rotator 11 comes into contact with the outer surface of the lower end of the rotatable door 23, and is used by projecting upward from the surface of the case 12 and the floor 22.

An elastic material 24 such as rubber is provided on one side surface of the rotor 11, that is, a contact surface with the lower end outer surface of the rotary door 23.
Is installed. At the upper end of the lock member 17, a concave portion 25 for inserting a coin or the like used at the time of unlocking is formed.

In the above configuration, when the rotor 11 is projected upward from the case 12 and the floor 21, the lock member 17 is used.
A coin or the like is inserted into the concave portion 25 at the upper end of the rotor 11 to release the engagement of the claw 16 of the lock member 17 with the step portion 14 at one end of the rotor 11, and in this state, the upper surface of the other end of the rotor 11 is pressed with a finger. As a result, one end of the rotor 11 protrudes upward from the case 12, and the portion may be pinched by a finger to rotate the rotor 11 by 180 degrees. Rotor 11 protruding upward from case 12
Also, when putting in the case 12, a coin or the like is inserted into the concave portion 25 at the upper end of the lock member 17, and the step portion on the other end side of the rotor 11 is
