Definitions

  • the present invention relates to a lock device equipped with an opening support mechanism and a sliding door including the lock device equipped with an opening support mechanism, the lock device being applied to a sash window assembly.
  • a relatively large force is required to overcome an inertial force and open a sash window assembly, especially a sliding door, that is closed and larger in size as well as heavier than a normal fixture.
  • a lock device equipped with an opening support mechanism is used in such sash window assembly (sliding door) requiring the relatively large force at the beginning of opening it.
  • As such lock device equipped with an opening support mechanism there is known a "hook lock equipped with an opening support mechanism" disclosed in Japanese Patent No. 4426477 , for example.
  • FIG. 11 is a longitudinal profile of the traditional hook lock equipped with an opening support mechanism disclosed in Japanese Patent No. 4426477 , as seen from the front of a sliding door.
  • the hook lock equipped with an opening support mechanism includes, in a case 110 mounted to a sliding door 102, a hook bolt 115 engaged with and disengaged with a striker 104 attached to a jamb, a thumb turn shaft 120 formed integrally with a thumb turn lever that switches the hook bolt 115 between a locked position and an unlocked position, a trigger 117 restricting the switching of the hook bolt 115 in an unlocked state to the locked position, and an opening support mechanism.
  • the opening support mechanism of the hook lock equipped with an opening support mechanism includes a kick lever 142 pivotally supported to be able to reciprocate between a standby position in the case 110 and an operated position in which the lever partially protrudes from the case 110, a return spring 146 biasing the kick lever 142 to be moved toward the standby position, and an operation handle 145 switching the position of the kick lever 142 to the operated position against the biasing force of the return spring 146.
  • the kick lever 142 and the hook bolt 115 are connected to be able to operate in conjunction with each other via a link bar 147.
  • the hook bolt 115 is operated in conjunction with a handle operation of the operation handle 145 to be unlocked from the locked state when the sliding door 102 that is fully closed is forcibly opened with the operation handle 145.
  • the operation unit (such as the thumb turn lever) performing locking and unlocking and the operation handle operating the opening support mechanism are provided separately.
  • Such hook lock equipped with an opening support mechanism allows for successive operations to unlock and open a window but, as an operation to close the window and lock is performed independently, the operation becomes cumbersome.
  • the structure of the hook lock equipped with an opening support mechanism is also complex.
  • the mechanisms to operate the kick lever and the hook bolt are all accommodated in one case so that the case has a complex structure and, at the same time, it is difficult to dispose the kick lever at an arbitrary position away from the position of the operation handle thereof and is also unable to dispose a plurality of kick levers. Moreover, there needs to be solved a problem that limitations of the case make it difficult to increase the size of each component to transmit a large torque with an operation lever.
  • DE 101 07 028 A1 relates to a sliding door with an energy accumulator.
  • the sliding door is associated with an energy accumulator which is formed as a spring-loaded stopper for the door panel.
  • the energy accumulator is supported by the door panel and stops at the wall opening and assists the movement of the door panel from the closed position when relaxed.
  • the door panel is held closed by an unlockable snap connection supported by same.
  • the snap connection is spring-loaded in the locking direction and is coupled to a handle lever on the door through a traction member.
  • Yet another object is to allow the operations of locking, unlocking, and kicking-out of the sliding door to be performed with one operation handle not to impair the design.
  • a lock device equipped with an opening support mechanism includes: an operation mechanism mountable to a stile of a sliding door and configured to be operated with an operation handle; the opening support mechanism configured to kick out the sliding door; a link bar configured to connect between the operation mechanism and the opening support mechanism; and a lock configured to unlock or lock the sliding door in conjunction with turning of the operation handle.
  • the operation mechanism includes a slider configured to move vertically in conjunction with the turning of the operation handle.
  • the opening support mechanism includes: a guide pin attachment unit connected to the link bar at a predetermined interval from the slider, the link bar being connected to the slider and transmitting a vertical motion of the slider; a kick-out arm configured to turn in order to press one of a sliding door jamb and a vertical frame in conjunction with the vertical motion of the guide pin attachment unit; and an operation delay unit configured to delay a kick-out operation by the kick-out arm in order for the kick-out operation by the kick-out arm in the opening support mechanism to be performed after the sliding door is unlocked by the lock
  • the lock device further comprises an idle lock prevention mechanism including a door stop portion, wherein the idle lock prevention mechanism is mountable to the stile of the sliding door while being biased in a direction at which the door stop portion protrudes from the stile, the idle lock prevention mechanism is configured to: be engaged with the link bar to inhibit the vertical motion of the link bar when the sliding door is positioned away from a frame body at a predetermined distance; and be brought into contact with one of the sliding door jamb and the

  • the guide pin 56 of the guide pin attachment unit 54 connected to the link bar 50 moves further upward.
  • the guide pin 56 is brought into contact with an upper wall of the oblique portion of the second guide groove 63a and pushes the upper wall of the second guide groove 63a upward. This allows the kick-out arm 63 provided with the second guide groove 63a to turn upward about the connecting pin 62.
  • the kick-out roller 64 pivotally fixed at the free end (turning end) of the kick-out arm 63 pushes the sliding door jamb and separates (or kicks out) the sliding door from the sliding door jamb.
  • the kick-out roller 64 keeps kicking out the sliding door until the guide pin 56 reaches an end of the oblique upward portion of the second guide groove 63a with the turning of the operation handle 20a.
  • FIGS. 8C and 9C illustrate the position of the operation handle 20a and the positional relationship between the resin nut 34 (contact portion 34a) and the pressing member 32 (flat surface 32a) at this time.
  • Each of the operation handle 20a and the resin nut 34 is turned less than 120° from the state in FIGS. 8A and 9A to reach the position illustrated in FIGS. 8C and 9C , in the present embodiment.
  • FIGS. 8C and 9C illustrate the state in which the operation handle 20a (and thus the contact portion 34a) is turned about 30° from the state in FIGS. 8B and 9B .
  • the guide pin 56 of the guide pin attachment unit 54 of the link bar 50 is in contact with the upper end of the bent portion of the second guide groove 63a of the kick-out arm 63 extending obliquely upward, and the operation handle 20a (contact portion 34a) is turned to the farthest position.
  • the flat surface of the contact portion 34a is in contact with the flat surface 32a of the pressing member 32 at an angle of about 30°.
  • the positional relationship between the two is thus unstable where moment in a reverse turning direction is acting on the contact portion 34a. Accordingly, when one lets go of the operation handle 20a in the state illustrated in FIGS. 8C and 9C , the operation handle 20a turns in a direction opposite to the direction in which the handle turns to reach the state in FIGS. 8C and 9C from the state in FIGS. 8B and 9B , whereby the contact portion 34a returns to the state illustrated in FIGS. 8D and 9D ( FIGS. 8B and 9B ). That is, the resin nut 34 turns automatically to return to the state in FIGS.
  • every turning of the operation handle 20a is exerted as a click motion.
  • the idle lock prevention mechanism 70 is then operated to prevent idle locking at the stage where the series of unlocking and kick-out operations of the sliding door is completed. This point will now be described.
  • the idle lock prevention mechanism 70 is provided at the appropriate position between the operation mechanism 20 and the opening support mechanism 60 along the link bar 50 that is disposed along the stile 2c.
  • FIGS. 10A to 10D are diagrams illustrating an operating procedure of the idle lock prevention mechanism 70 (unlinked unit) at the time of locking ( FIG. 10A ), unlocking ( FIG. 10B ), kicking out ( FIG. 10C ) and preventing idle locking ( FIG. 10D ).
  • the stile 2c of the sliding door and the sliding door jamb 1c are in contact with each other so that the door stop portion 72 is in contact with the sliding door jamb 1c or vertical frame against the biasing force of the coil spring 74.
  • the door stop portion 72 is thus held still on the side of the stile 2c, thereby allowing the link bar 50 to move freely through the groove 72b of the door stop portion 72.
  • the sliding door is separated from the sliding door jamb 1c in this state, whereby a force from the sliding door jamb 1c against the coil spring 74 does not act on the door stop portion 72.
  • This causes the door stop portion 72 to be on the verge of protruding outward from the stile 2c of the sliding door but, since a lower portion of the notch 55 of the link bar 50 is in contact with a lower side wall of the groove 72b of the door stop portion 72, the protrusion of the door stop portion 72 is prevented.
  • FIG. 10D illustrates the state in which the link bar 50 is moved down from the state in FIG. 10C as the kick-out roller 64 once kicked out returns to the original standby position automatically. That is, the door stop portion 72 restrained by the link bar 50 is released at the instant when the notch 55 of the link bar 50 is in alignment with the groove 72b while the link bar 50 moves downward, whereby the biasing force of the coil spring 74 causes the door stop portion 72 to pop out of the stile 2c through the notch 55 of the link bar 50.
  • the idle locking of the lock can thus be prevented.
  • the continuity of operation can be ensured because the operation of locking or unlocking and kicking out can be performed all by one operation handle in an orderly manner.
  • the operation handle itself is increased in size to allow for the use of relatively large moment by the operation handle.
  • the idle locking of the lock can be prevented automatically by a simple structure of the contact between the door stop portion and the link bar, whereby one can obtain an effect such as the simplified operation of the lock device as a whole.
  • the operation associated with the sliding door including unlocking to opening the window or closing the window to locking can be successively performed all by one operation handle.
  • the opening support mechanism can be disposed at an arbitrary position and, as needed, a plurality of the mechanisms can be disposed by using the link bar to link the operation of the opening support mechanism of the sliding door and the mechanism operating the operation handle.
  • the design is not impaired since the operations of locking, unlocking, and kicking-out of the sliding door are performed with one operation handle.
