Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings.

In fig. 1 and 2, the lock handle device 1 includes a handle housing 2 (fig. 2), an inner tube 3, a lock member 4, a handle 5, a spring member 6, a locking mechanism 7, and a lock unit 8.

In fig. 2, 3, and 4, the handle housing 2 includes a bearing cylinder 9 extending in the front-rear direction and a flange 10 provided at a front end of the bearing cylinder 9, and as shown in fig. 3 and 4, a rear surface of the flange 10 is brought into contact with a front surface panel of a door D of the housing and fixed to the door D. A handle receiving recess 11 for receiving a handle plate portion 12 of the handle 5 is formed in the front surface of the flange portion 10.

In fig. 2, 3, and 4, the inner cylinder 3 is inserted into the bearing cylinder 9 of the handle housing 2 so as to be relatively rotatable about an axis by substantially 90 ° between the locked position and the unlocked position, and the inner cylinder 3 is provided so as not to be movable forward and backward with respect to the bearing cylinder 9 by the front flange portion 13 and the lock member 4 fixed to the rear end. As shown in fig. 1, the inner tube 3 is open toward the front, and the rear of the inner tube 3 is closed by an end wall 14. As shown in fig. 3, 4, and 7, the end wall 14 is exposed rearward of the bearing tube 9, and the lock member 4 is fixed to the rear surface of the end wall 14. As shown in fig. 2, the stopper projection 15 formed on the rear surface of the flange portion 13 is fitted into the substantially 90 ° arc-shaped recess 16 formed on the inner peripheral front edge portion of the bearing tube portion 9 of the handle housing 2, whereby the rotation range of the inner tube 3 with respect to the handle housing 2 is restricted to substantially 90 °. By changing the insertion angle of the inner cylinder 3 toward the bearing cylinder 9 by 180 °, the rotation direction of the inner cylinder 3 can be changed.

In fig. 2 to 4, the lock member 4 is fixed to the rear surface of the end wall 14 of the inner cylinder 3, and the lock member 4 is rotated forward and backward within a range of approximately 90 ° with respect to the handle housing 2 integrally with the inner cylinder 3 between a locked position extending in the vertical direction and locking the door D with respect to the housing and an unlocked position extending in the horizontal direction and releasing the door D with respect to the housing.

In fig. 1, the handle 5 has a substantially cylindrical handle shaft portion 17 and a handle plate portion 12, and the handle plate portion 12 extends in one direction (downward) from the front end of the handle shaft portion 17 in the axis orthogonal direction. The protrusion 18 on the outer periphery of the handle shaft portion 17 is fitted into the recess 62 on the inner periphery of the inner cylinder 3, and the handle shaft portion 17 is fitted into the inner cylinder 3 so as to be relatively movable within a predetermined range in the axial direction, although it cannot relatively rotate around the axis with respect to the inner cylinder 3.

Therefore, the handle 5 is slidable in the front-rear direction with respect to the inner tube 3 between a retracted position (fig. 3) retracted into the handle housing 2 and a projected position (fig. 4) projected from the handle housing 2, and is also rotatable with respect to the handle housing 2 at the projected position between a locked position (solid line in fig. 5) and an unlocked position (imaginary line in fig. 5) integrally with the inner tube 3 and the lock member 4.

As shown in fig. 3 and 5, in the retracted position, the handle plate portion 12 is retracted into the handle support recess 11 of the handle housing 2 and cannot be rotated. As shown in fig. 1, the handle plate portion 12 has an opening 19 that communicates with the handle shaft portion 17 and is open to the front, and a flap support concave portion 20 that extends on the outer edge of the opening 19.

In fig. 1, 3, and 4, the spring member 6 is inserted between the end wall 14 of the inner tube 3 and the rear end of the handle shaft portion 17, and urges the handle 5 in the forward projecting direction.

The locking mechanism 7 has a bolt 21 and a rotor cam 22, and the locking mechanism 7 is assembled into each of housing spaces 23 and 24 (fig. 3 and 4) in the handle shaft portion 17, interlocked with a locking/unlocking operation of the lock unit 8, and restrains or releases the handle shaft portion 17 in the front-rear direction with respect to the inner cylinder 3 at the retracted position.

The lock unit 8 is assembled and fixed to a lock housing space 25 (fig. 3, 4) of the handle shaft portion 17, and the lock unit 8 is driven so that the bolt 21 is lifted to the unlock position by the rotor cam 22 by rotation of the rotor 26 from the lock position to the unlock position by key operation.

The keeper 21 is assembled into a keeper housing space 23 of the handle shaft portion 17, is freely advanced and retreated in the radial direction between a locking position protruding from the handle shaft portion 17 in the radial direction of the handle shaft portion 17 as shown in fig. 3 and 8 and an unlocking position retracted into the handle shaft portion 17 as shown in fig. 4 and 9, and is biased to the locking position by a spring 27.

The rotor cam 22 is assembled to the rotor cam receiving space 24 of the handle shaft portion 17. The rotor cam 22 transmits the rotation of the rotor 26 of the lock unit 8 to the keeper 21, and the rotor cam 22 has a driving engagement portion 29 (fig. 8 and 9) that engages with a driven engagement portion 28 of the keeper 21, and the rotor cam 22 is axially rotatable between a lock position (fig. 8) and an unlock position (fig. 9). The rotor cam 22 rotates in the unlocking direction in accordance with the rotation of the rotor 26 in the unlocking direction, and pushes up the bolt 21 to the unlocking position (fig. 3 and 8).

In fig. 3 and 4, a lock accommodating space 25, a rotor cam accommodating space 24, and a bolt accommodating space 23 are formed in the handle shaft portion 17 from the front to the rear. The lock housing space 25 is open forward through the opening 19. A bearing hole 30 for supporting the rear end portion of the rotor cam 22 to be freely rotatable is formed at the rear end of the handle shaft portion 17. A sector-shaped engagement recess 31 that regulates the rotation angle of the rotor cam 22 is formed on the outer peripheral side of the bearing hole 30. A bolt entrance opening 33 is formed in a lower portion of the peripheral wall 32 of the bolt housing space 23. As shown in fig. 8 and 9, the bolt housing space 23 holds the bolt 21 so as to freely extend and retract in the radial direction from the bolt entrance/exit opening 33. As shown in fig. 1, an opening 34 for inserting a lock fixing member 35 is formed on the right side of the peripheral wall 32 of the lock housing space 25.

As shown in fig. 1 and 3, the inner tube 3 has a through opening 37 corresponding to the bolt entrance opening 33 of the handle shaft portion 17 in a peripheral wall 36 of the inner tube 3. When the handle 5 is in the retracted position (fig. 3), as shown in fig. 3 and 8, the through opening 37 faces the bolt insertion/removal opening 33, and the bolt 21 protruding from the bolt housing space 23 is inserted downward and moved to the lock position, thereby restraining the handle 5 to the retracted position. When the handle 5 is not in the retracted position, as shown in fig. 4 and 9, the keeper 21 is pressed by the peripheral wall 36, thereby holding the keeper 21 in the unlocked position. A long guide hole 38 extending forward continuously from the through opening 37 is formed in the peripheral wall 36 of the inner cylinder 3, and a projection 39 of the latch 21 is movably engaged with the long guide hole 38.

Therefore, after the top portion 45 of the keeper 21 is removed from the through opening 37, the handle 5 can move in the front-rear direction with respect to the inner cylinder 3 within a range in which the protrusion 39 moves along the long hole 38 (fig. 3, 4).

An opening 37 'and a long hole 38' having the same shape as the through opening 37 and the long guide hole 38 are provided at (above) a position of the peripheral wall 36 of the inner tube 3 which is rotationally symmetrical at 180 degrees with respect to the through opening 37 and the long guide hole 38. The head of the stopper bolt 61 screwed to the upper surface of the rear end portion of the handle shaft portion 17 is fitted into the opening 37 ' and the long hole 38 ', so that the range of relative movement in the axial direction of the handle 5 and the inner tube 3 is limited to the extension range of the long hole 38 ' (fig. 2 and 3).

As shown in fig. 2 and 3, a groove portion 40 that faces the through opening 37 and the guide long hole 38 and extends forward and backward in the axial direction is formed in the bearing cylinder portion 9 of the handle housing 2. When the door bolt 21 protrudes from the through opening 37 to the lock position (fig. 3 and 8), the lower end of the protrusion 39 is exposed from the groove portion 40 to the outside lower side of the bearing cylinder portion 9.

As shown in fig. 1 and 8, the keeper 21 has a head 41 and a pair of parallel legs 42 extending from the head 41. A projection 39 projects from the top 45 of the head 41. The driven engagement portion 28 is provided on the front surface side of one leg portion 42. The head portion 41 penetrates the bolt insertion and removal opening 33 of the handle shaft portion 17 at the lock position and projects outward downward (fig. 8). The latch 21 is assembled in the latch accommodating space 23 in the handle shaft portion 17 so as to be relatively movable in the radial direction, and the shaft cylindrical portion 43 of the rotor cam 22 is inserted between the pair of leg portions 42 in the front-rear direction. The bolt 21 is biased to the lock position by interposing the spring 27 between the front end of the leg portion 42 and the inner periphery of the handle shaft portion 17.

As shown in fig. 1 and 8, the driven engagement portion 28 of the latch 21 is formed of a recess provided on the front surface side to receive the driving engagement portion 29 of the rotor cam 22, and the driven engagement portion 28 has an abutment surface 44 with which the driving engagement portion 29 abuts.

As shown in fig. 3 and 8, the rotor cam 22 is assembled into the handle shaft portion 17 so as to be rotatable around the shaft between the lock position and the unlock position. As shown in fig. 1 and 3, the rotor cam 22 includes a shaft tube portion 43, a flange portion 46, a driving engagement portion 29, and a protrusion 47, wherein the shaft tube portion 43 is fitted with the rotor 26 of the locker unit 8, the flange portion 46 is formed at a front end portion of the shaft tube portion 43, the driving engagement portion 29 is provided to protrude from a rear surface of the flange portion 46, and the protrusion 47 is formed to extend in an axial direction on an outer periphery of the shaft tube portion 43. The driving engagement portion 29 engages with the driven engagement portion 28 of the keeper 21. As shown in fig. 2 and 8, the cylindrical shaft portion 43 of the rotor cam 22 engages the protrusion 47 with the fan-shaped engaging recess 31, and the cylindrical shaft portion 43 is supported at the rear end portion by the bearing hole 30 of the handle shaft portion 17. Therefore, the rotor cam 22 is rotatable around the shaft between the lock position (fig. 8) and the unlock position (fig. 9) in the angular range of the fan-shaped engagement recess 31 integrally with the rotor 26 of the lock unit 8 with respect to the handle shaft portion 17.

The drive engaging portion 29 is disposed: when the rotor cam 22 rotates to the unlock position, the driving engagement portion 29 engages with the abutment surface 44 of the driven engagement portion 28 of the latch 21, and the latch 21 moves to the unlock position.

As shown in fig. 1 and 3, the lock unit 8 is assembled to the handle 5 in such a manner that the guard shield 50 is sandwiched between the lock housing 48 and the fixing ring 49. The lock case 48 is cylindrical and has a threaded portion 51 on the outer periphery, and a pair of flat surfaces 52 parallel to the axis on opposite side surfaces of the lock case 48. The fixing ring 49 has an annular groove 53 at the outer periphery, and this fixing ring 49 is screwed and fixed to the outer periphery of the lock case 48. The guard 50 is made of a hard material and is effective against violent damage caused by a drill bit or the like.

As shown in fig. 1 and 3, the lock unit 8 is fixed into the handle shaft portion 17 by inserting a fixing member 35 of the handle shaft portion 17 in the axis orthogonal direction through a fixing-fitting insertion opening 34.

As shown in fig. 2 and 3, a push type electromagnet (japanese: プッシュソレノイド)55 electrically connected to a control center is fixed to the rear surface side of the lower flange portion 10 of the handle case 2 via a mounting fitting 56. The push-type electromagnet 55 is used to press the keeper 21 located at the lock position to the unlock position in response to an electric signal from the control center, and to fix the tip of the push rod 57 to the projection 39 of the keeper 21 projecting downward from the groove 40 to the bearing cylinder 9.

A cover member 58 is attached to the lower rear portion of the handle case 2, and the cover member 58 is made of a hard material for making it difficult for a force from the front to approach the lower end portion of the push rod 57 of the push-type electromagnet 55. This can prevent the push rod 57 from being pushed upward from the lower end side by a tool while punching a hole in the front surface panel of the door D, thereby preventing improper unlocking.

A micro switch 59 for detecting the position of the handle 5 and transmitting an electric signal to a control center is attached to the rear surface side of the upper flange portion 10 of the handle housing. The base end side of the sensor pin 60 penetrating the flange portion 10 so as to be movable in the front-rear direction abuts on the actuator of the micro switch 59, and the front end of the sensor pin 60 protrudes from the front surface of the handle support concave portion 11.

Now, the following procedure will be explained: from the state shown in fig. 3 and 8 in which the door D is locked to the housing in the closed state by the locking member 4, the locking of the door D is released, and after the door D is opened and the work is completed, the door D is closed and locked again.

In the state shown in fig. 3 and 8, the lock member 4 is in the locked position, the handle 5 is retracted into the handle housing 2, the door bolt 21 is in the locked position in which it engages with the through opening 37 of the inner cylinder 3, and the rotor 26 and the rotor cam 22 of the lock unit 8 are also all in the locked position.

From this state, when the key is inserted into the lock and rotated by substantially 90 ° clockwise in fig. 8, the driving engagement portion 29 of the rotor cam 22 presses the abutment surface 44 of the driven engagement portion of the keeper 21 and draws in the keeper 21 toward the unlock position. The door latch 21 is pulled out from the through opening 37 of the inner tube 3, and the handle 5 is pushed out from the handle housing 2 by the spring member 6, so that the door latch 21 is held at the unlocked position by the peripheral wall 36 of the inner tube 3 in the state of fig. 4 and 9.

Thus, when the handle 5 is gripped and the handle 5 is rotated by 90 ° counterclockwise, for example, the lock member 4 is rotated to the unlock position together with the inner tube 3 and is moved out of the corresponding engagement portion of the housing, which is not shown, so that the door D can be opened.

When the door D is closed after completion of a required operation, the handle 5 is rotated by 90 ° clockwise together with the inner tube 3 and the lock member 4 to return to the locked position, and the handle 5 is pushed into the handle housing 2, the door bolt 21 is pushed by the spring 27 to automatically protrude from the handle shaft portion 17 and engage with the through opening 37 at a position where the through opening 37 of the inner tube 3 faces the groove portion 40 of the handle housing 2, and the door D is locked to the housing.

Further, the unlocking operation can be performed by exciting the electromagnet 55 as shown in fig. 10 by a remote operation from a control center or the like without operating the lock. When the electromagnet 55 is excited, the push rod 57 protrudes upward to push up the latch 21 to the unlock position and push out the handle 5 from the handle case 2, so that the lock does not need to be operated. This also enables remote irregular unlocking. By adding an electric authentication device to restrict the unlocking authority as required, the safety can be improved, the unlocking means can be diversified, and the use of the pop-up lock handle device can be greatly expanded.
