Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a handle device that is attached to a cover body for opening and closing an opening/closing door or an inspection port of various devices, and is used when opening and closing the door.

(Technical background of the invention and its problems) In buildings such as high-rise buildings, large Western-style opening doors are increasingly being used. Such a door can be opened and closed by pulling or pushing a handle toward you, and is difficult or impossible to open and close if the handle is not operated.

By the way, conventionally, a handle is simply attached to the opening/closing door, so that an outsider or a child can easily operate the handle, which not only poses a security problem but is also extremely dangerous. Therefore, a locking device is usually attached to the opening/closing door, but if the handle is made inoperable, the locking device becomes unnecessary, which simplifies the configuration and is economical.

In addition, if the lids used to open and close the entrances of caves and manholes, or the lids used to open and close the inspection ports of various devices, are easily or impossible to open and close by operating the handle, when necessary. It is preferable and safe to be able to operate the handle only.

(Purpose of the invention) An object of the invention is to provide an opening/closing handle device that allows the handle to be operated only when opening/closing an opening/closing body.

(Summary of the invention) This invention provides an engaging piece and a lock boss on the lock rotor located at the key hole position of the main body, and also forms a guide groove and a locking hole on the seat to which the main body is attached, and places the lock rotor at the locking hole position. It is characterized in that the locking boss is locked in the locking hole at the same time as the locking piece is turned in the locking hole of the handle, thereby making it impossible to operate the handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an opening/closing handle device according to the present invention. This opening/closing handle device includes a main body 1. This main body 1 has a front disk portion 1A and a shaft portion 1B, and the shaft portion 1B is fitted into a cylindrical portion 2a of a disk-shaped round seat 2. The round seat 2 is directly attached to an opening/closing body such as an opening/closing door. A handle 3 is housed between the small-diameter half of the disk portion 1A and the round seat 2. This handle 3 has a tapered engagement hole 3a in the center, and shafts 3b at both ends.
3b is integrally formed. These axes 3
b and 3b are rotatably pressed against the back surface of the disk portion 1A by a spring plate 4. Handle 3 of disc part 1A
A keyhole 1a is formed nearby, and a locking rotor 5 is rotatably fitted into a hole 1b provided coaxially with the keyhole 1a of the disc portion 1A. As shown in FIG. 3A, this locking rotor 5 has a locking boss 6 on one surface, and protrusions 5a and
5a is provided. An engagement piece 7 is attached to this locking rotor 5. That is, this engagement piece 7 is attached with the lock boss 6 passing through it and the protrusions 5a, 5a being fitted into the notches 7a, 7a. As shown in FIG. 3B, a key set hole 5b is formed in the other surface of the lock rotor 5, and a key 8 is inserted into this key set hole 5b through the key hole 1a.
The tip of the is inserted. Therefore, by rotating the key 8, the lock rotor 5 is rotated, and the lock boss 6 and the engaging piece 7 are also rotated accordingly.

As shown in FIG. 3C, the spring plate 4 has a through hole 4a through which the lock boss 6 passes, and a protrusion 4b for guiding the lock boss 6 is formed on the periphery of the hole 4a. As shown in FIG. 2, this spring plate 4 is screwed to the back surface of the disk portion 1A, and presses the shafts 3b, 3b of the handle 3 and the engaging piece 7 against the back surface.

As shown in FIG. 4, the round seat 2 has a guide groove 2b.
is formed. A locking hole 9 is formed in communication with one end of the guide groove 2b. This lock hole 9
has a step 9a for locking.

Next, the operation of the opening/closing handle device of the present invention will be explained.

First, as shown in FIG. 5, when the end of the lock boss 6 is not engaged with the step 9a of the locking hole 9, the engaging piece 7 is out of the engaging hole 3a of the handle 3. The handle 3 can be rotated about the shafts 3b, 3b, and protruded toward the front as shown by the two-dot chain line in FIG. Therefore, by grasping and operating the handle 3, the lock boss 6 can be engaged in the guide groove 2b and guided as shown in FIG. 4, and the main body 1 can be rotated.
By operating a lock mechanism (not shown) interlocking with the main body 1, it becomes possible to open and close the opening/closing door and the like.

Next, when the tip of the key 8 is inserted into the key set hole 5b of the lock rotor 5 through the key hole 1a and the lock rotor 5 is rotated, as shown in FIG.
The lock boss 6 also rotates, and its end engages with the stepped portion 9a of the lock hole 9. Further, the engagement piece 7 also rotates and enters the engagement hole 3a of the handle 3. Therefore, the handle 3 cannot be projected forward, and the main body 1 cannot be rotated either. Therefore, it is possible to reliably prevent outsiders or young children from opening and closing the door.

(Effects of the device) According to the device, a lock rotor is provided at the key hole position of the main body, a lock boss and an engagement piece are provided, a guide groove and a lock hole are formed in the seat to which the main body is attached, and the lock rotor is rotated at the lock hole position to engage the engagement piece into the engagement hole of the handle and at the same time engage the lock boss with the lock hole, so that the handle can be protruded and operated as needed. Therefore, it is possible to provide a simple opening and closing handle device that can be opened and closed with a simple structure without attaching a locking device to the opening and closing body, and can be kept in the closed state. This can prevent dangers associated with children operating the handle, and is also effective in crime prevention.
