As shown in Fig. 2, the lock piece 8 of one of the options is composed of a plate-like block, the base end portion is a mounting portion toward the handle base 1, and the front end portion is a separation side end portion of the latch 67. The latch engagement portion provided on the front end side of the lock piece 8 is constituted by the latch guide portion 82 and the latch catch portion 83, wherein the front end portion of the latch guide portion 82 is formed in a substantially trapezoidal cross section. Or a substantially triangular shape or a curved surface of the above-mentioned shape, and when the handlebar 4 is pulled up or fallen, the latch 67 in the forward state is sequentially moved and guided to the backward direction and the forward direction, and the latching portion is latched. The 83 is formed in a substantially concave shape adjacent to the proximal end side of the latch guide portion 82, and can be engaged with the latch 67 in the forward state when the handlebar 4 is laid down. The lock member engaging portion 84 provided on the proximal end side of the lock piece 8 is formed to be engageable before the handle bar 4 is laid down The locking groove of the locking member 73 of the advanced state. Thus, the locking piece 8 is fixed to the bottom surface of the handle base 1 through the fixing shaft, and extends from the bottom surface of the handle base 1 in a substantially horizontal direction (a substantially right angle with respect to the sill) into the part space S. The way to install. Thus, by attaching the locking piece 8 to the handle base 1 and on the side opposite to the latch 67 of the dial lock 6, the latch of the detachable latch 67 is configured by the lock ‧ unlocking action on the dial lock 6 The lock engaging portion 81, on the other hand, on the side opposite to the lock member 73 of the cylinder lock 7, the lock member engaging portion of the detachable lock member 73 is disposed by the lock lock/unlock operation of the cylinder lock 7 84.

On the other hand, as shown in Fig. 3, the lock lever 9 is formed of a plate-like block, the base end portion is a shaft branch portion supported by the handle base 1, and the front end portion is a rotation side end portion. The latch engagement portion 91 provided on the front end side of the lock lever 9 is formed in a substantially planar shape that can abut against the latch 67 in the forward state when the handlebar 4 is laid down. The lock member engaging portion 92 provided on the proximal end side of the lock lever 9 is constituted by the lock groove 93, the cam inclined surface 94, and the inclined surface 95, wherein the lock groove 93 is fitted to the forward state when the handle bar 4 is laid down The lock member 73 is formed such that the cam inclined surface 94 is formed obliquely to the front end portion side in the direction in which the lock groove 93 is expanded, and the inclined surface 95 is connected to the cam inclined surface 94 to be inclined toward the direction gradually separated from the latch engagement portion 91. It is formed on the front end side. The cam inclined surface 94 and the inclined surface 95 are used to guide the forward-locking member 73 to the front end portion of the lock lever 9 when the handlebar 4 is pulled up, and are guided in the opposite direction when the handlebar 4 is laid down, and utilize the forward state. The lock member 73 is pressed toward the latch 67. In this way, the lock lever 9 pivots the pivot portion of the base end portion to the handle base 1 through the pivot shaft and the coil spring. The bottom surface of the handle base 1 extends from the bottom surface of the handle base 1 in a substantially horizontal direction into the component space S, and is attached in a vertical direction, that is, by rotating the outer peripheral surface of the cylinder lock 7 to impart potential energy. Thus, by attaching the lock lever 9 to the handle base 1, on the side opposite to the latch 67 of the dial lock 6, the latch 6 can be abutted by the locking and unlocking operation of the dial lock 6. The latch engaging portion 91 is disposed on the side opposite to the lock member 73 of the cylinder lock 7, and the lock member engaging portion 92 of the detachable lock member 73 is disposed by the locking and unlocking operation of the cylinder lock 7.

The lock lever device H has such a configuration, and when the lock piece 8 is attached to the component space S (locking position P), the handlebar 4 accommodated in the handle base 1 is locked by the dial 6 and the cylinder. The lock 7 is double-locked, and the lock lever 4 is unlocked by unlocking the two locks 6, 7 (hereinafter, simply referred to as "double lock type"). On the other hand, when the lock lever 9 is attached to the component space S (locking position P), the handle base 1 and the handlebar 4 are locked by the dial lock 6 and the cylinder lock 7, and by One of the dial lock 6 or the cylinder lock 7 is unlocked to release the lock lever 4 (hereinafter referred to as "emergency unlocking mode"). In any case, as described above, the handle base 1 is fitted into the longitudinally long receiving hole provided in the sill from the front side of the sill, and the U-shaped gasket plate is fitted from the back side of the handle base 1 and The screw is locked and fixed to the sill.

Fig. 4 is a view showing an example of use when the lock lever device H is constructed in a double lock form.

In this lock device H, the solution of the dial lock 6 is previously determined. The lock symbol column is assigned to the user who is permitted by the owner or manager of the machine to use the machine, and the key 74 for unlocking the cylinder lock 7 is delivered to the user.

When the user closes and locks the door sill in order to use the machine, the sill is closed, and as shown in FIG. 4 (1), the dial is locked while the handle bar 4 is placed on the handle base 1 and stored. The scale disc 61 of 6 is rotated into an arrangement other than the particular unlock symbol sequence assigned. In this way, the lock plate 65 of the dial lock 6 rotates and becomes the position of the lock portion 65 locking the end portion of the lock member 66, so that the lock plate 65 prevents the backward movement of the slide member 66, and The dial lock 6 is in a locked state. In this locked state, even if the handlebar 4 is to be pulled up from the handle base 1, the latch 67 of the dial lock 6 in the forward state is engaged with the latching catching portion 83 of the locking piece 8 to restrict it. Moving to the latch guide 82 prevents the handle lever 4 from rotating in the pulling direction. When the user inserts the key 74 into the key hole of the cylinder lock 7 and rotates it in the upward locking direction, the rotor 71 rotates and the lock member 73 advances and is caught by the lock member engaging portion of the lock piece 8 ( Lock groove) 84. In this manner, even if the handlebar 4 is rotated from the handle base 1 in the pull-up direction, the lock member 73 of the forward state of the cylinder lock 7 is caught by the lock member engaging portion (lock groove) 84 of the lock piece 8, Therefore, the rotation of the handlebar 4 in the pulling direction is prevented. In this way, the handlebar 4 is double locked (double lock).

Conversely, when the user unlocks and opens the sill in order to use the machine, the key 74 is inserted into the keyhole of the cylinder lock 7 and rotated in the unlocking direction from the above-described threshold. In this way, the rotor 71 of the cylinder lock 7 rotates, and the lock member 73 retreats. The engagement with the lock member engaging portion (lock groove) 84 of the lock piece 8 is released. Further, here, the locking of the cylinder lock 7 is first released, and the dial lock 6 is in a locked state, that is, the latch 67 at the front end of the slider 66 is engaged with the latching portion of the locking piece 8. In the state of 83, the movement of the slider 66 in the backward direction is blocked by the lock plate 65, so that it is controlled so that the rotation of the handle bar 4 in the pulling direction cannot be performed. Next, the scale disk 61 of the dial lock 6 is rotated so as to be an arrangement of the specific unlock symbol sequence to be assigned. In this way, the lock plate 65 of the dial lock 6 is rotated back to the original position, and is returned to the position where the locking end portion of the lock plate 65 is not engaged with the stopper portion of the slider 66, so The slide member 66 is prevented from moving backward in the direction of the main body portion of the dial lock 6, and the scale key 6 is in an unlocked state. In this unlocked state, when the handle base 4 is rotated from the handle base 1 in the pull-up direction, the latch 67 of the dial lock 6 is latched from the lock piece 8 by the guidance of the latch guide 82. The catching portion 83 is sequentially moved to the retreating direction and the advancing direction. As shown in Fig. 4 (2), the latching guide portion 82 is disengaged from the locking piece 8 and the handle bar 4 is pulled up to a predetermined angle. status. When the handlebar 4 is rotated around the handle shaft 2, the buckle 5 connected to the handlebar 4 through the handle shaft 2 is detached from the bracket portion on the fixed frame side of the machine storage case body or the like. The restriction on the fixed frame of the sill is lifted, and the sill is opened by directly pulling the handlebar 4 forward.

Thus, in the lock device H of the double lock type, in the state in which the handle bar 4 is placed on the handle base 1 in a state of being folded, the dial lock 6 and the cylinder lock 7 are double-locked (double-locked), and the scale is set. The unlocking operation is performed on both sides of the disc lock 6 and the cylinder lock 7, so that the locking of the handlebar 4 can be given Lifted.

Next, an example of the case where the lock lever device H is configured to be in an emergency unlock mode will be described with reference to Fig. 3.

In this lock device H, the unlock symbol column of the dial lock 6 is assigned in advance to the user who is allowed to use the machine by the owner or manager of the machine. On the other hand, the cylinder lock 7 is normally set to a locked state, for example, a manager having a wider authority than the user (hereinafter referred to as a superior authority), and the handlebar 4 can be used without using the unlocking symbol row described above. In the manner of the pulling operation, the key 74 of the cylinder lock 7 is given to the superior authority.

When the user closes and locks the door sill, the user closes the sill and causes the handle bar 4 to fall down and is stored on the handle base 1 to rotate the scale disk 61 of the dial lock 6 into a Arranges other than the specific unlock symbol column assigned. In this way, the lock plate 65 is rotated and moved to the position where the locking end of the lock plate 65 collides with the stop portion of the slide member 66, so that the backward movement of the slide member 66 is blocked by the lock plate 65, and the dial is blocked. The lock 6 is in a locked state. In this state, the lock lever 9 to which the latch 67 of the front end of the slider 66 is engaged cannot be rotated backward in the restriction releasing direction (upward direction in FIG. 3). In the locked state above the dial lock 6, when the handlebar 4 is to be rotated from the handle base 1 in the pull-up direction, the handlebar 4 is rotated only by a slight angle and at the front end of the lock member 73 of the cylinder lock 7. When pushed to the cam inclined surface 94 of the lock lever 9, the rotation in the pulling direction is blocked.

In the locked state above the dial lock 6, it is limited to the superior authority, and the handle can be used without using the specific unlock symbol column to be assigned. The lever 4 is rotated in the lifting direction. As described above, the superior authority is given the key 74 of the cylinder lock 7, so that when the user forgets the release symbol column of the dial lock 6, or because the unlocking symbol column of the dial lock 6 is unknown, the outsider and the intrusion When the scale disk 61 is rotated to an irregular angle, and the dial lock 6 is unintentionally set in an emergency state such as when the lock state is reached, the superior authority uses the key 74 to unlock the cylinder lock 7, The handlebar 4 can be operated and the sill can be opened. In addition, the lock state of the dial lock 6 can be reset. At this time, the superior authority inserts the key 74 into the key hole of the rotor 71 of the cylinder lock 7, and drives the internal lock mechanism in the release direction in accordance with the required key tooth code. In this manner, when the rotatable rotor 71 is rotated in the unlocking direction by the key 74, the lock member 73 is pulled from the insertion opening 45 of the handlebar 4 into the inside of the handlebar 4, and the front end portion of the lock member 73 is The snap-fit state of the lock groove 93 of the lock lever 9 is released. When the dial lock 6 is in the locked state, since the locking end portion of the lock plate 65 is in a position colliding with the stopper portion of the slider 66, the backward movement of the slider 66 is blocked by the lock plate 65, and The lock lever 9 cannot be rotated backward in the restriction release direction (upward direction in FIG. 3). However, when the cylinder lock 7 is unlocked by the key 74, the lock member 73 is retracted to the position where the lock lever 9 is not engaged, so that the handlebar 4 is not interfered by the lock lever 9, and the handlebar 4 can be Pull out from the handle base 1. That is, even if the scale discs 61 of the dial lock 6 are not arranged in the unlock symbol row, the lock of the handlebar 4 can be unlocked by unlocking the cylinder lock 7 with the key 74. Furthermore, when the lock state of the dial lock 6 is reset, after the door sill is opened, the irregular lock state is performed by operating an appropriate reset means from the back side of the sill. Released for repair processing.

Conversely, the user gives the threshold in order to use the machine. When unlocking and opening, the scale disc 61 of the dial lock 6 is appropriately rotated forward and backward in such a manner as to be assigned to its own unlocking symbol. When the symbols of the scale disk 61 are arranged in the assigned unlock symbol sequence, the dial lock 6 is in an unlocked state. That is, the locking end portion of the lock plate 65 is moved to a position where it is not engaged with the stopper portion of the slider 66, and the backward movement of the slider 66 in the direction toward the main portion of the dial lock 6 is not prevented. status. At this time, the cylinder lock 7 is in a locked state, and the front end portion of the lock member 73 is engaged with the lock groove 93 of the lock lever 9, and the snap-in state is caused by the spring member rotating the lock lever 9 toward the cylinder lock 7. It is given potential energy to maintain it. In this way, the handlebar 4 is restrained from the lodging and storage position in the front opening 10 of the handle base 1.

In this state, when the handlebar 4 is rotated from the handle base 1 in the pull-up direction, the front end portion of the lock member 73 is pressed against the cam inclined surface 94 of the lock groove 93 of the lock lock lever 9, so that the lock lever 9 is attached. The rotation is retracted toward the restriction releasing direction (upward direction in FIG. 3) around the pivot, and the lock lever 9 pushes up the latch 67 at the front end of the slider 66 to move backward. In the stage of pulling the handle bar 4 out of the handle base to a certain angle, the front end portion of the lock member 73 is no longer pressed against the lock lever 9, so that the lock lever 9 is biased by the spring member. Go back to the approximate horizontal standby position. Furthermore, the slider 66 is also advanced back to the original position by the potential energy of the spring member.

When the handlebar 4 is pulled up and rotated, or pulled up after the rotation When the handlebar 4 is held by the hand and the rotation is performed around the handle shaft 2, the buckle 5 connected to the handlebar 4 through the handle shaft 2 is detached from the bracket portion on the fixed frame side of the machine storage case body or the like. The restriction of the sill to the fixed frame is released, and the sill is opened by directly pulling the handlebar 4 to the front.

Thus, in the unlocking device H in the emergency mode, in the state in which the handlebar 4 is undulated and stored on the handle base 1, the dial lock 6 is locked with the cylinder lock 7, usually if the dial is locked The symbols of 6 are arranged in an unlocked symbol sequence, so that the lock of the handlebar 4 can be released and operated, and the cylinder lock 7 can be used for unlocking and unlocking in an emergency when the symbol is forgotten to be unlocked. Further, only one of the dial lock 6 or the cylinder lock 7 can be used as a cylinder lock.

As described above, according to the lock lever device H, a form is formed by arranging the dial lock 6 and the cylinder lock 7 on the handlebar 4, and between the handle base 1 and the handlebar 4 and on the dial Between the lock 6 and the cylinder lock 7, the latch 67 of the dial lock 6 and the lock position P of the lock member 73 of the cylinder lock 7 are set, and the lock piece 8 is fixed to the handle base 1 side and is disposed at the lock The position P is held, and the handlebar 4 accommodated in the handle base 1 is double-locked by the dial lock 6 and the cylinder lock 7, and the unlocking operation is performed to release the lock of the handlebar 4. Therefore, with the dial lock 6 and the cylinder lock 7, only the lock piece 8 of a simple shape and configuration can be used, and the lock lever device having the true double lock function can be realized relatively easily. Then, by establishing the correlation between the dial lock 6 and the cylinder lock 7 and assembling into the handlebar 4, the entire device can be easily obtained even if it is made thin. A very large number of individual keys, in addition, can also be provided for the provision of a double lock function latching system for the purpose of security enhancement.

Furthermore, according to the lock lever device H, a form is formed by arranging the dial lock 6 and the cylinder lock 7 on the handlebar 4, and between the handle base 1 and the handlebar 4 and on the dial lock 6 and the cylinder lock 7, the latch 67 of the dial lock 6 and the lock position 73 of the lock member 73 of the cylinder lock 7 are set, and the locking piece 8 of the optional part is fixed to the handle base 1 side and The lock position P is set, and the handlebar 4 accommodated in the handle base 1 is double-locked by using the dial lock 6 and the cylinder lock 7, and the two sides are unlocked to move the upper handlebar 4 The lock is released. In the locking position P, a lock lever 9 is provided instead of the above-mentioned locking piece 8 of the selective part. The base end portion of the lock lever 9 is pivotally supported on the handle base 1 side, and the front end portion is turned toward the circle by the spring member. The cylinder lock 7 rotates in the direction and gives potential energy, and the handle base 1 and the handlebar 4 are locked by the dial lock 6 and the cylinder lock 7, and the lock of the handlebar 4 is given by unlocking either side. Lifted. Therefore, as long as the minimum number of selective parts is changed, one lock device can selectively have a double lock function and a single lock function, and a plurality of parts of the entire lock handle device can be shared, and the cost can be reduced. Then, by establishing the correlation between the dial lock 6 and the cylinder lock 7 and assembling the handlebar 4, even if the entire device is configured to be thin, a large number of individual keys can be easily obtained, and can be selectively correspondingly The requirement for the provision of a latching system with a double lock function for the purpose of security enhancement, or the provision of a latching system with a Master Lock function for the purpose of facilitating the management of cabinets.
