Definitions

  • This invention is concerned with a hook bolt lock for e.g. a sliding window or sliding door, comprising a hook bolt mounted for pivotal movement in a lock casing about a fixed axis between a first position, in which an end of the hook bolt projects from the casing, and a second position, in which said end is retracted into the casing, an operating handle which lies flush or substantially flush with the surface of the window or door frame when the lock is mounted therein, and which is mounted for sliding movement in the casing between first and second end po - sitions corresponding to the first and second positions respectively of the hook bolt, and a transmission mechanism comprising a rotary member which is operatively connected to the handle in such a manner that sliding movement of the handle causes rotation of the member to take place, and further which is operatively connected to the hook bolt in such a manner that rotation of said member causes pivotal movement of the hook bolt to take place.
  • a further disadvantage of the lock of US-A 2736185 resides in that the overall dimensions of the lock are determined by the "throw" of the levers of the transmission mechanism required to give on the one hand an adequate rotation of the hook bolt and on the other a favourable mechanical advantage in the mechanism.
  • a hook bolt lock of the type set out in the first paragraph above, in that a first link operatively connects the handle to the rotary member, being pivotally connected to the rotary member, and a second link is pivotally connected at one end to the rotary member and at the other to the hook bolt and thus provides the operative connection therebetween, the pivotal connections being such that the application of pressure to the projecting end of the hook bolt, when the latter is in its first position, is effective, through the second link, to urge the rotary member to rotate and thus to urge the first link in one direction, and in that locking means is provided for preventing such movement of the first link in said one direction and thus movement of the hook bolt from its first position, in response to such applied pressure, said locking means comprising an abutment which is mounted on the lock casing and against which an abutment surface provided on the first link is pressed when the latter is urged in said one direction.
  • the pivotal connections of the links with the rotary member are disposed both at the same side of a line extending through the axis of the rotary member and the pivotal connection of the second link with the hook bolt, and thus urging the first link in said one direction is effective to urge the handle from its first to its second end position in this case, furthermore, the abutment is movable between an operative position, in which it is operatively engageable by the abutment surface on the first link, and an inoperative position, and cam means is provided movable with the operating handle, when the latter is moved from its first to its second end position, and engageable with a cam surface associated with the abutment, for camming the abutment out if its operative position, the arrangement being such that the operating handle is connected to the first link by a lost motion arrangement allowing movement of the handle relative to the first link sufficient to effect the camming action.
  • a positive stop can be applied to the first link, and thus to the hook bolt, when the latter is urged out of its projecting position by the application of pressure to the projecting end thereof, but this stop does not interfere with the normal operation of the lock by moving the sliding handle.
  • actuating means comprising an actuator which is urged into a position in which it projects from the casing at the same side as the hook bolt end, but is retractable into the casing, such retraction of the actuator causing the abutment to be urged into its operative position, while movement of the actuator to its projecting position causes the abutment to be moved to its inoperative position.
  • the actuating means is effective to render the locking means operative when the window or door in which the lock is incorporated is closed, but does not interfere with the operation of the lock when said window or door is open.
  • the abutment which may be fixed in the casing in this case, and indeed may be constituted by the pivot pin on which the rotary member is mounted, is engaged by the abutment surface on the first link when the handle is moved into its first end position, and in fact defines said position.
  • the second embodiment of lock may also comprise further locking means for locking the first link, and thus the hook bolt, in the second position of the latter, said further locking means comprising a further abutment surface provided on the first link and a further abutment carried by a support pivotally mounted on the casing for movement into and out of an operative position in which it can operatively engage said further abutment surface, actuating means being provided for moving the abutment into and out of its operative position, said actuating means comprising an actuator which is urged into a position in which it projects from the casing at the same side as the hook bolt end, but is retractable into the casing, and the support and actuator being connected by a pin-and-slot connection such that movement of the actuator between its projecting and retracted positions causes pivoting movement of the support to take place.
  • the hook bolt can be retained in its retracted position while the window or door is open, the further locking means releasing the first link only upon retraction of the actuator, e.g. by closing the door or window.
  • the risk of damage to the hook bolt end or the frame of the door or window or both by collision therebetween is minimised.
  • first and second embodiments referred to above are suitable for use where the handle is accessible only at one side of the door or window. Where, on the other hand, it is desired to provide a handle at each side of the door or window, it will be desirable also for the operation of the lock to be disabled when the window or door is closed and to this end, in a third embodiment of lock in accordance with the invention auxiliary locking means is provided for locking the hook bolt, transmission mechanism and operating handle against movement in the casing when the hook bolt is in its first position.
  • auxiliary locking means comprises a locking member movable between an advanced, locking, position and a retracted position in the casing, said member having an abutment surface engageable with a stop associated with the hook bolt, transmission mechanism and operating handle, e.g. mounted on the hook bolt.
  • Such locking member may be moved between its advanced and retracted positions by means of a key-actuated lever.
  • the first lock in accordance with the invention (see Figs. 1 to 3) comprises a casing 2 made up of profiled front and back plates 2,2'. Within the casing 2 a pivot pin 3 is provided for a hook bolt generally designated 4, which pivots on the pin 3 between a first position (Fig. 1), in which a hook end 5 thereof projects from the casing, and a second position (Fig. 2), in which the end 5 is retracted into the casing.
  • the hook bolt 4 carries a pin 32 which projects through a curved slot 33 formed in the back plate 2' and is engaged by a spring 31 (Fig. 3) to urge the hook bolt 4 into its first, projecting, position.
  • an operating handle 7 is provided, which lies flush or substantially flush with the surface of the frame of the door or window in which the lock is incorporated.
  • the handle 7 is slideable, between first and second end positions corresponding to the first and second positions of the hook bolt 4, linearly in a recess (not shown) formed in said frame and comprises an integral pin slideable in slots 15,15' formed in the plates 2,2' of the casing.
  • the handle 7 is operatively connected to the hook bolt 4 by a transmission mechanism generally designated 6, now to be described.
  • the transmission mechanism 6 of the first lock comprises a rotary plate member 12 pivotally mounted on a pivot pin 11 carried by the casing 2. Pivotally connected, by a pin 13, to the member 12 is a first link 8 having a slot 16 which receives the pin of the handle 7. Also pivotally connected, by a pin 14, to the member 12 is one end of a second link 9, the other end of which is pivotally connected, by a pin 10, to the hook bolt 4.
  • locking means which comprises an abutment 26 carried on a lever 24 which is pivotally mounted in the casing 2 on a pin 20 for movement into and out of an operative position (see Fig. 1) in which the abutment 26 is disposed in the path of an abutment surface 28 formed on the first link 8.
  • actuating means generally designated 17 comprising a plate-like actuator 18 movable between a projecting position (Fig.2), in which it projects from the casing 2, at the same side thereof as the hook bolt 4, and a retracted position (Fig.l), in which it is held accommodated within the casing, e.g. when the door or window in which the lock is incorporated is closed.
  • the actuator 18 has formed therein a slot 19 in which the pin 20 is accommodated and also carries-a pin 21 slideable in a slot 22 formed in the casing 2.
  • a spring 23 mounted on the back plate 2' (Fig.3) acts on the pin 21 thus to urge the actuator 18 into its projecting position.
  • a further spring 27, of lesser force, is also provided which acts to urge the lever 24 into its operative position upon retraction of the actuator 18 (see Fig.l), but when the actuator 18 is moved to its projecting position the pin 21 engages with a cooperating recess formed in one edge of the lever 24 and cams the latter out of its operative position.
  • the pin of the handle 7 For enabling the handle 7 to be moved from its first to its second end position the pin of the handle 7 carries a camming ring 29 which cooperates with an inclined cam surface 30 of the lever 24 to cam the latter out of its operative position.
  • This camming action is achieved, furthermore, by the pin of the handle 7 being movable relative to the first link 8 along the slot 16 therein, which thus provides the necessary lost motion to enable the lever 24 to be retracted before the pin engages the end of the slot 16 and begins to move the hook bolt 4 out of its first position.
  • the second lock in accordance with the invention is generally similar, except as now described, to the first lock.
  • the pins 13,14 are disposed at opposite sides of a line (shown in chain-dot) extending through the pins 10,11.
  • the rotary plate member 12 is urged, through the second link 9, in a clockwise direction and thus, through the first link 8, urges the handle 7 in a direction away from its second end position, i.e. in a direction opposite to its "opening" movement.
  • locking means comprising an abutment provided by the pin 11 and a cooperating abutment surface 35 formed on the first link 8.
  • abutment provided by the pin 11 and a cooperating abutment surface 35 formed on the first link 8.
  • the cooperation between the abutment and abutment surface serves to define the first end position of the handle 7 so that pressure applied to the hook bolt end 5 as aforesaid merely serves to urge the abutment surface 35 against the abutment (11); it will of course be appreciated that the first link 8 is restrained against lateral pivotal movement on the pin 13 by the engagement of the pin of the handle 7 in the slots 15,15'.
  • the second lock also has further locking means for locking the first link 8, and thus the hook bolt 4, in the second position of the latter, that. is to say in its retracted position.
  • the further locking means comprises a lever 36 pivotally mounted in the casing 2 and having at its lower end an abutment 39 which can engage with a further abutment surface 34 formed on the first link 8. The lever 36 is so positioned that the abutment surface 34 engages the abutment 39 when the handle 7 is in its second end position.
  • actuating means generally designated 17 is provided of a similar construction to the actuating means 17 of the first lock.
  • the actuator 18 is urged into a projecting position by means of the spring 23.
  • the pin 21 is accommodated in a profiled slot 38 formed in the lever 36, the arrangement being such that, as the actuator 18 is moved from its projecting position into the casing 2, the lever 36 is pivoted clockwise (viewing Fig.5) to move the abutment 39 out of operative position.
  • the abutment 39 is held out of its operative position.
  • the actuator 18 moves to projecting position, the pin 21 thus causing the lever to pivot anti-clockwise to bring the abutment 39 into the operative position.
  • the abutment 34 has an inclined camming face associated therewith so that, as the handle is moved to its second end position, the first link 8 is cammed over in the region of the slot 15 to move the abutment surface 34 past the abutment 39.
  • the third lock in accordance with the invention is generally similar to the second lock, but is provided with auxiliary locking means operable e.g by means of a cylinder lock (not shown), so that provision can in this case be provided for operating the lock as aforesaid from either inside or outside.
  • the auxiliary locking means comprises a lever 41 slideable transversely along a guide rail 40 and having a recess 42 which can be engaged by the operating tongue (not shown) of a cylinder lock assembled in a key hole 43 formed in an extension of the casing 2.
  • the lever 41 carries a pin 48 which is captive in a slot 47 formed in a locking plate 44, the latter also having a vertical slot 45 formed therein accommodating a pin 46 mounted in the casing 2.
  • the locking plate 44 has a should 49 which provides an abutment for an abutment pin 50 carried by the hook bolt 4, the arrangement being such that when the hook bolt is in its projecting position, the pin 50 abuts against the shoulder 49. In this position, therefore, the hook bolt cannot be moved to its second position even by operation of the handle 7, but rather the bolt 4, transmission mechanism 6 and handle 7 are all locked against movement within the casing.
  • auxiliary locking means of the aforementioned type may also be used in the first lock described above.
  • auxiliary locking means may also be used in the first lock described above.
  • locks of other types may also be contemplated in this connection.
