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

The conventional open state holding device for a rotary door will be described below. There are a state in which the device 1 is pivotally supported by the horizontal shaft 2 with respect to the case 1 and is housed in the case 1, and a state in which it projects upward from the case 1. It is provided with a substantially semi-circular rotor 3 which is rotatable in a range of 180 degrees between them. When the case 1 is housed in the outer case 4, the open state holding device for the rotary door is embedded at a predetermined position on the floor 5. Then, the rotor 3 is rotated so that the rotor 3 comes into contact with the outer surface of the lower end of the opened rotary door 6 when the rotary door 6 is to be opened. It is designed to project.

More specifically, the rotor 3 is attached to the case 1
The operation of rotating between the state where the rotor 3 is housed inside and the state where the rotor 3 projects upward from the case 1 is performed by hand, and one end side that is the projecting start end side of the rotor 3 is made heavy, so
The posture can be maintained when the case 1 is rotated by 80 degrees and is projected upward from the case 1. When projecting the rotor 3 housed in the case 1 from the case 1,
By pressing the lighter upper surface of the other end side of the rotor 3 with a finger, one end side of the rotor 3 projects upward from the case 1, and the portion is pinched by the finger to rotate the rotor 3.

[0005]

However, in the above-mentioned conventional open state holding device for a rotary door, the rotor 3 is used.
When the heel of the high heel is placed on the lighter upper surface of the other end of the rotor 3 in a state where the heel of the high heel is placed in the case 1, the heel of the high heel enters the case 1 and the heel is cut off, or even the foot is damaged. There was a problem such as breaking down.

The present invention solves such a problem. Even when a heel of a high heel is placed on the upper surface of the other end side of the rotor in a state where the rotor is housed in the case, the heel of the high heel remains in the case. It is an object of the present invention to provide a highly safe rotary door open state holding device that does not enter.

[0007]

In order to solve this problem, according to the present invention, when the revolving door is opened by being buried in the floor so that the upper end thereof is flush with the floor surface, almost half of the floor surface is opened. An open state holding device for a rotary door, wherein a circular rotor is projected to stop the closing movement of the rotary door, and is locked to one end of the rotor when the rotor fits in a case and does not project. The gist of the present invention is a device for holding an open state of a revolving door in which a lock member having a claw is provided in a case.

[0008]

With this structure, the claw of the lock member is locked to the step portion on the one end side when the rotor is housed in the case, so that even if the heel of the high heel is placed on the upper surface of the other end side of the rotor. It is possible to provide a highly safe open state holding device for a rotary door without the heel of a high heel entering the case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5, reference numeral 11 denotes a case 12 which is pivotally supported by a horizontal shaft 13 at the upper end of the case 12
It is a substantially semi-circular rotor that is rotatable within a range of 180 degrees between a state where it is housed inside 12 and a state where it projects upward from the case 12. Since the one end side which is the projecting start side is made heavy, the rotor 11 can maintain its posture when the rotor 11 is rotated 180 degrees and projected upward from the case 12. Further, both end portions of the substantially semicircular outer peripheral surface of the rotor 11 are cut off with a thin thickness to form step portions 14 and 15.

Inside the case 12, the rotor 11 is a case.
The rotor 11 is provided with a claw 16 that is locked to the step portion 14 on the one end side and the step portion 15 on the other end side in the state of being housed in the case 12 and the state of being completely projected upward from the case 12. A lock member 17 for stopping rotation is provided. The lower end of this lock member 17 is pivotally supported by a horizontal shaft 18, and the claw 16 is stepped 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 in which it is locked with the step portion 15. Therefore, when the rotor 11 is housed in the case 12, the claw 16 of the lock member 17 is locked to the step portion 14 on the one end side, and when the rotor 11 is completely projected upward from the case 12, the other end is formed. The claw 16 of the lock member 17 is engaged with the step portion 15 on the side and holds each posture unless the lock is released. In addition, the rotor 11 is housed in the case 12 and the stepped portion on one end side
When 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. Further, when the rotor 11 projects completely upward from the case 12 and the claw 16 of the lock member 17 is locked to the step 15 on the other end side, the step 14 on the one end side contacts the upper end of the case 12.

When the case 12 is housed in the outer case 21, the open state holding device for the rotary door is embedded in a predetermined position on the floor 22 and opened when the rotary door 23 is desired to be opened. The rotor 11 is rotated so that the rotor 11 comes into contact with the outer surface of the lower end of the rotary door 23, and is projected upward from the surface of the case 12 and the floor 22 for use.

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 recess 25 for inserting a coin or the like used when unlocking is formed.

In the above structure, when the rotor 11 is projected upward from the surface of the case 12 and the floor 21, the lock member 17
Insert a coin or the like into the recess 25 at the upper end of the rotor 11 to release the lock of the claw 16 of the lock member 17 with respect to the step portion 14 at one end side of the rotor 11, and press the other end side upper surface of the rotor 11 with a finger in that state. As a result, one end side of the rotor 11 projects upward from the case 12, and the portion may be pinched with a finger to rotate the rotor 11 180 degrees. Rotor 11 protruding upward from case 12
Also when putting the inside of the case 12, insert a coin or the like into the recess 25 at the upper end of the lock member 17, and
Release the locking of the claw 16 of the lock member 17 with respect to the 15
Pick 11 with your finger and rotate 180 degrees.

[0014]

As described above, according to the present invention, since the claw of the lock member is locked to the step portion on one end side when the rotor is housed in the case, the upper surface on the other end side of the rotor is formed. Even if the heel of the high heel is placed on the inside of the case, the heel of the high heel does not enter the case, and it is possible to provide a highly safe rotary door open state maintaining device.
