Abstract

PROBLEM TO BE SOLVED: To provide a pop-out type door lock handle device that has a high protection performance against breakdown and further can be small-sized and reduced in cost.SOLUTION: A lock handle device comprises a handle case 2, an inner cylinder 5, a lock member 6, a handle shaft 7, a spring member 8, a locking mechanism 9, and a lock unit 10. A handle plate 12 comprising a hard material is fixed to a front end of the handle shaft 7. The handle plate 12 has an opening 12a exposing a front end of the lock unit 10, and covers a front surface of a flange part 4 of the handle case 2 when the handle shaft 7 is positioned rearward. A portion exposed to the front surface side of a door is entirely covered by the handle plate 12 comprising the hard material, so that the protection performance against breakdown is high. Furthermore, a conventional handle greatly exposed to the front surface side of the door 1 becomes unnecessary, and the flange part 4 of the handle case for receiving this large handle is reduced, and thereby cost reduction thanks to a small size is attained.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, the lock handle device includes a handle case 2, an inner cylinder 5, a locking member 6, a handle shaft 7, a spring member 8, a locking mechanism 9, and a lock unit 10.

  1, 4, 5, and 6, the handle case 2 includes a shaft tube portion 3 that extends in the front-rear direction and a flange portion 4 provided at the front end portion of the shaft tube portion 3. The first door 1 is brought into contact with the front surface of the door 1 and fixed to the first door 1.

  1, 7, 8, and 9, the inner cylinder 5 is rotatably inserted into the shaft cylinder part 3 of the handle case 2, and the shaft cylinder part is formed by the front flange part 5 a and the rear stop plate 13. 3 cannot move forward and backward. The inner cylinder 5 opens forward, and the rear is closed by an end wall 5b.

  In FIG. 1, the locking member 6 is connected to the rear end portion of the inner cylinder 5, and is integrated with the inner cylinder 5 between a locking position where the door 1 is locked with respect to the housing and an unlocking position where the door 1 is released. Rotate forward and backward.

  1, 10, 11, and 12, the handle shaft 7 is configured in a substantially cylindrical shape, is non-rotatably inserted into the inner cylinder 5, and protrudes from the handle case 2 at a rear position where it is immersed in the handle case 2. It is slidable back and forth with respect to the front position, and can be rotated between the locking position and the unlocking position integrally with the inner cylinder 5 at the front position.

  In FIG. 1, the spring member 8 is inserted between the end wall 5 b of the inner cylinder 5 and the handle shaft 7 via a cover plate 14 and urges the handle shaft 7 forward with respect to the inner cylinder 5.

  In FIG. 1, the locking mechanism 9 is provided at the rear part in the handle shaft 7, and restrains or releases the handle shaft 7 with respect to the inner cylinder 5 when the handle shaft 7 is in the rear position.

  In FIG. 1, the lock unit 10 is assembled and fixed to the front portion of the handle shaft 7 and is driven directly or indirectly so that the lock mechanism 9 is restrained or released by rotation of the rotor 11 by key operation.

  1, 13, and 14, a handle plate 12 made of a hard material is fixed to the front end of the handle shaft 7. The handle plate 12 includes an annular protrusion 2 b having an opening 12 a that exposes the front end of the lock unit 10. The annular protrusion 12b protrudes rearward from the periphery of the opening 12a and is fitted and fixed to the inner periphery on the front end side of the handle shaft 7. The handle plate 12 covers the front surface of the collar portion 4 of the handle case 2 when the handle shaft 7 is in the rear position. That is, the handle plate 12 is configured to have a similar outer shape with a slightly larger area than the front surface of the flange portion 4 of the handle case 2, and a standing edge portion that surrounds the periphery of the flange portion 4 and a recess 12 c in which the flange portion 4 is fitted 12d. When the handle shaft 7 is in the rear position, the flange 4 is fitted into the recess 12 c of the handle plate 12, and the front surface of the flange 4 is covered with the handle plate 12.

  In FIG. 1, the locking mechanism 9 receives the rotational force from the rotor 11 of the lock unit 10, and engages and disengages the locking operation unit with respect to the inner cylinder 5. The body portion of the lock unit 10 is formed with an outer peripheral screw portion 10a over the entire length, and the opposite side surfaces are formed with flat portions 10b that are deleted in parallel with each other, and the cross section of the body portion is a so-called oval shape. It is formed. As shown in FIGS. 10, 11, and 12, the middle wall 7 a of the handle shaft 7 is formed with an oval opening 7 b, and the rear end of the body portion of the lock unit 10 is fitted therein. Therefore, the lock unit 10 cannot rotate with respect to the handle shaft 7.

  In FIG. 1, a fixing ring 15 is screwed into the outer peripheral screw portion 10 a of the lock unit 10, and is in contact with the rear end of the annular protrusion 12 b of the handle plate 12. A U-shaped fixing bracket 16 is inserted into a diameter-direction receiving hole of the handle shaft 7 and fixed with screws 17. When the two parallel leg portions 16a (FIG. 16) of the fixing bracket 16 are engaged with the outer peripheral groove 15a (FIG. 15) of the fixing ring 15, the lock unit 10 is moved in the front-rear direction with respect to the handle shaft 7. Fixed. Since the parallel contact surface 16b of the leg portion 16a is in contact with the flat surface portion 10b of the lock unit 10, the lock unit 10 cannot rotate with respect to the handle shaft 7 by this.

  The annular protrusion 12b of the handle plate 12 has an outer protrusion 12e, which is prevented from rotating with respect to the handle shaft 7 by being fitted into a rotation stopper recess 7c formed on the inner periphery of the front end of the handle shaft 7. The screw 18 is coupled to the handle shaft 7. As shown in FIGS. 13 and 14, an inner flange 12 g having an oval opening 12 f that fits into the body of the cylinder lock unit 10 is formed at the rear end of the annular protrusion 12 b.

  A guide screw 19 screwed into the rear portion of the handle shaft 7 engages with a guide groove 5c (FIG. 7) formed in the inner cylinder 5 in the front-rear direction. It is impossible to rotate, and it can slide back and forth.

  The pop handle door lock handle device according to this embodiment is covered with a handle plate 12 made of a hard material, so that the portion exposed to the front side of the door 1 is covered with a hard material. The conventional handle that is exposed to a large distance is omitted, and the collar portion of the handle case that receives this large handle is also reduced, so that the cost can be reduced by downsizing.
