Description

200407495 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a flat handle device that hides the whole or main part of the handle into a front recess of the box when the handle is not in use. [Prior Art]-It is known that there is a handle device (for example, Patent Document 1), which is used to rotate the handle about the lateral pivot axis of the base end when the handle is used, and to protrude from the front concave portion of the box, When using the handle, hide the handle in the front recess of the box body, and lock the handle in the box body with a locking mechanism built in the lower part of the box body. -It is urged, however, that this flat handle device is designed and manufactured on the premise that it is used in a dust-free indoor environment. Recently, when the device is installed in an outdoor machine door that is not expected by a retailer, it will be in the lock cylinder. The keyhole, the outer peripheral surface of the lock cylinder, or the side surface of the flash lock block the dust, or the remaining moisture is frozen in the above part, causing problems such as poor operation of the lock cylinder and the latch. Patent Document 1 Japanese Utility Model Publication No. 8 2 1 2 [Contents] Problems to be Solved by the Invention The object of the present invention is to provide a lock cylinder and a latch which can solve the problems caused by clogging or freezing of dust. Flat handle device with poor locking action. Angle ^: Method of the problem In the following, the component symbols in the drawings are used for explanation. The main purpose of the flat handle device of the present invention is that when the handle 2 is used, the handle 2 is rotated around the lateral pivot 5 of the base end portion 4 and protrudes from the front concave portion 3 of the box body 1. When the handle 2 is not used, the handle 2 is hidden in the front recess 3, and

Description of the invention (2) The lock mechanism 6 built in the lower part of the box body 1 and the handle 2 is locked in the box body 1, among which the lock cylinder 1 for housing the lock mechanism 6 7 Between the lower side portion 2 2 a of the lock case 2 2 and the inner side surface 1 a of the box body 1, a communication gap 2 6 opened toward the front side of the box body 1 is formed, and a latch formed in the lock case 2 2 is formed. The lower end portion of the receiving groove 25 opens toward the communication gap 26, and a communication hole 28 opening toward the communication gap 26 is formed in the lower inner surface of the lock cylinder receiving hole 27 of the lock case 22, and the above The inner end of the lock cylinder receiving hole 27 is connected to the above-mentioned latch receiving groove 25. The lower end 2 5 a of the invention functions in the flat handle device. The key hole 21 of the lock cylinder 17 enters the lock cylinder receiving hole. 2 7 dust rainwater, dust entering the latch receiving groove 25 from the gap between the handle 2 and the front recess 3, and dust entering the lock cylinder receiving groove 27 from the gap between the lock cylinder 17 and the lock shell 22 And rainwater are introduced into the communication gap 26 through the openings at the lower ends of the communication holes 28 and the latch accommodating grooves 25, and from the positive of the communication gap 26. The surface side openings 2 6 a are discharged. The rainwater dripped into the flat handle device can be used as a spring force for pushing the dust out of the communication gap 26 to flush the dust out. [Embodiment] In the illustrated embodiment, the flat handle device is a pull-out rotary operation type mechanism, which is provided with: a box body 1 fixed to the lintel 12; and disposed in the front and rear directions of the box body 1 and accommodated in The box body 1, and a locking shaft 1 4 of a locking plate 1 3 which can be fastened to and detached from the receiving portion on the side of the fixed frame body is fixed at the rear end; the front recess 3 can be freely entered and stored in the box body 1, and With the lateral pivot 5

Description of the invention (4) The leading edge portion 8 formed in the handle 2 extends from the front side portion of the front end portion 7, and the end surface 7a of the front end portion 7 and the front recessed portion A gap between the inner side surface 3a of 3 is shielded, and a front edge receiving portion 9 for receiving the front edge portion 8 when the handle 2 is hidden and rotated is formed on the front portion of the lock case 22. A first concave-convex portion 10 is formed along the longitudinal direction of the handle 2 on the back side of the front edge portion 8, and a first concave-convex portion 10 is formed on the front side of the front-edge receiving portion 9 to mesh with the first concave-convex portion 10. 2 irregularities 1 1. In the flat handle device of the embodiment, since the aforementioned front edge portion 8 shields the gap between the end surface 7 a of the front end portion 7 and the inner surface 3 a of the front concave portion 3, it is possible to prevent the violent illegal unlocking with a screwdriver. Even if the front end of the screwdriver is inserted from the gap between the front end surface 8 a of the leading edge portion 8 and the inner side surface 9 a of the leading edge accommodation portion 9 and the front end of the screwdriver is slid along the front face of the front edge accommodation portion, The second concave and convex portion 1 on the front face of 9 is an obstacle that prevents the front end of the screwdriver from moving. Therefore, regardless of the angle at which the screwdriver is inserted, the front end of the screwdriver cannot enter the back side of the front edge portion 8. Also, the leading edge portion 8 cannot be cut. Therefore, the aforementioned protective function of the leading edge portion can be maintained. The pitch dimension of the first uneven portion 10 and the second uneven portion 11 is set to be smaller than the width dimension of the front end of the screwdriver, even if the front end of the screwdriver extends from the front end portion 8 a of the front edge portion 8 to the front edge portion receiving portion 9. After inserting the gap between the inner side 9a, even if the front end of the screwdriver does not slide along the front face of the leading edge accommodation portion 9, it can be prevented from being inserted through the meshing gap of the first uneven portion 10 and the second uneven portion 11 Insert the front end of the screwdriver. In addition, it is possible to insert a wider gap than the front end of the screwdriver from the meshing gap of the first uneven portion 10 and the second uneven portion 11.

W-ptd Page 9 200407495 V. Description of the invention (5) When the metal strip plate with a finer degree is used and the handle 2 is pushed up, the metal strip plate may be broken or bent, and illegal unlocking cannot be performed. In addition to those shown in the above embodiments, the flat handle device applicable to the present invention also uses a horizontal pivot to pivotally mount the base end portion of the handle on the box body, and uses a small screw in the front-rear direction to lock the unit. The cymbal area is installed on the back of the box body, and the action protrusion provided on the back of the base end portion of the handle is inserted into the passive hole of the central portion, and the action protrusion is used to press the edge of the passive hole. [Effects of the invention] _The flat handle device of the present invention is connected between the side surface portion 2 2 a below the lock case 2 2 and the inner side surface 1 a of the box body 1 to form a communication gap opened toward the front side of the box body 1 26, and the lower end portion of the latch accommodating groove 25 of the lock case 22 is opened toward the communication gap 26, and the communication hole 28 opened toward the communication gap 26 is formed in the lock cylinder of the lock case 22 The inner surface of the lower side of the hole 27 allows the inner end of the lock cylinder receiving hole 27 to communicate with the lower end 2 5 a of the flash lock receiving groove 25, so even if it is installed on outdoor equipment, it can be greatly suppressed. In the case of the keyhole 21 of the lock cylinder 17, the outer peripheral surface of the lock cylinder 17 or the side of the latch 16, or dust remaining in the part, the moisture can become trapped, and a lock cylinder 17 and the latch are obtained. Flat handle device with extremely excellent movement stability of the lock 16.
