Abstract

An independently interactive interconnected lock includes an interconnecting mechanism that retracts a latchbolt and a deadbolt when an inner handle is moved between an up position, an intermediate position and a down position. The deadbolt is retracted by a deadbolt lock mechanism as the inner handle moves from the up position to the intermediate position. The latchbolt is retracted by a latchbolt lock mechanism as the inner handle continues to move from the intermediate position to the down position. When the inner handle is moved to the up position, both the latchbolt and deadbolt are extended and the deadbolt lock mechanism is disconnected from the latchbolt lock mechanism such that manipulation of the latchbolt lock mechanism to retract the latchbolt does not retract the deadbolt. The inner handle operates with low handle torque because the deadbolt and the latchbolt are not retracted simultaneously.

Description

LOCK INTERCONNECTED INDEPENDENTLY INTERACTIVE TECHNICAL FIELD This invention relates to interconnected locks. The interconnected locks are locks in which the outside of the door perishes with separate conventional locks comprising a hook bolt lock mechanism in the lower part and a blind bolt lock mechanism in the upper part. However, inside the door, the hook bolt and the blind bolt are interconnected so that when turning the inner handle the blind bolt automatically retracts as the hook bolt retracts.

DETAILED DESCRIPTION OF THE RELATED ART On the closed external side, a door adapted with an interconnected closure seems to have two separate conventional closures. Normally the upper hook seems to be a conventional blind but operated by a key to drive a blind bolt and the lower lock looks like a normal cylindrical or tubular lock that drives a hook bolt. However, inside, the two locks are interconnected.

A main advantage of the interconnected locks that simply come out of a closed area. With the blind bolt and hook bolt seamers coming out of a closed area, two movements are required, turning a rotating butterfly piece to retract the blind bolt and rotating the inner handle to retract the hook bolt. To exit through an interconnected lock requires only a single movement. By turning the inner handle of the interconnected lock, the blind bolt and the hook bolt are simultaneously retracted. The convenience provided by the interconnection described above, however, is a security disadvantage for conventional interconnected locks of the prior art. If a bandit can remove or remove the end handle it may be possible to gain access from inside the closed area through the missing bolt lock to the inner spindle and other components of the blind bolt lock rotated by the inner handle. In such a case, the interconnection of an interconnected lock of the prior art between the hook bolt lock components and the blind bolt lock will allow the bandit to retract the blind bolt as well as the hook bolt by manipulating the components in the lock interconnected on the inner side of the door. When the blind bolt and hook bolt are installed separately, the Failure of the hook bolt lock mechanism does not affect the safety of the blind bolt lock mechanism. Because hook bolt locks, such as cylindrical locks and tubular locks, are generally less resistant to attack than blind bolt locks, the overall safety of interconnected locks of the prior art is less for an installation using a bolt. Blind completely separate and independent and hook bolt lock. There is a need for an interconnected lock design where the blind bolt and hook bolt mechanisms interact to provide the advantages of an interconnected lock, yet which is as secure as if it were installed separately and blind bolt and bolt lock mechanisms Hook operated independently. Because of the ease with which you can get out of a closed area, interconnected locks are often installed for use by elderly or weak people. The speed of operation and simplicity of using the interconnected lock is particularly valuable in an emergency, such as a fire. The benefits may be greater when the occupant of the closed room is an elderly person and / or has reduced mental capacities, given that they can not remember to rotate the rotating wing piece of a dead bolt installed separately before attempting to exit via the closed door. Nevertheless, these advantages for the elderly and mentally disabled people are not parallel due to the current design of interconnected locks for those who are physically disabled, weak, injured or disabled. Conventional interconnected locks simultaneously retract the hook bolt and blind bolt as the inner handle is rotated. The simultaneous operation of the blind bolt and bolt mechanisms requires more torque than the operation of these elements separately. Older and weaker people may not be able to easily produce the required increased torque, making it more difficult to operate the interconnected lock for whom the lock offers some of the greatest advantages. The use of lever handles to provide greater torque, as used in public buildings to improve access by the handicapped, exacerbates the safety disadvantage described above because a bandit can use a lever handle to produce more torque. twisting and separating the hook bolt lock portion of an interconnected lock. Consequently, there is a need for an interconnected lock that does not it requires more torque to operate than the torque required to operate a conventional blind bolt or a conventional cylindrical lock separately. Another disadvantage of conventional interconnected locks is that they can simplify the process to exit to a closed area, but not the process of closing the door. The blind bolt portion of the interconnected lock can still be closed separately by rotating the rotating wing piece inside the door after the door is closed. This is often not done. An improved interconnected lock design could be convenient to allow the blind bolt to extend as easily as it retracts.

DESCRIPTION OF THE INVENTION Having in mind the problems and shortcomings of the prior art, it is therefore an object of the present invention to provide an interconnected lock which is safer than conventional interconnected locks, particularly when the lever handles are installed. It is another object of the present invention to provide an interconnected lock that requires operation of less handle torque to operate the lock that is required to operate the conventional interconnected locks that simultaneously retract the hook bolt and the blind bolt. A further object of the invention is to provide an interconnected lock that simplifies the closing process by extending the blind bolt with the inner handle, as well as retracts it. It is still another object of the present invention to provide an interconnected lock that allows the lock state to be quickly determined from the position of the inner handle. Still other objects and advantages of the invention will be partly obvious and in part will be evident from the specification. The above objects and others, which will be apparent to those skilled in the art, are achieved in the present invention which is directed to an interactive interconnected lock having a hook bolt lock mechanism, a blind bolt lock mechanism and a interconnection mechanism connected between the hook bolt and the blind bolt lock mechanisms. The hook bolt lock mechanism can be mounted in a first hole through a door, and the blind bolt lock mechanism can be mounted in a second hole through the deflected door of the first hole. The hook bolt lock mechanism it includes a hook bolt and an outside handle that moves the hook bolt between hooked and unhooked positions. The blind bolt lock mechanism is mounted in a second hole through the deflected door, of the first hole. The blind bolt lock mechanism includes a blind bolt movable between the bolted or unbolted positions. The interconnection mechanism * can be operated by an inner handle to drive the hook bolt between the hooked and unhooked positions and the blind bolt between the bolted or unbolted positions. The inner handle can be moved between a top position, an intermediate position and a bottom position. The interconnection mechanism drives the blind bolt to the bolted position when the inner handle moves to the upper position. It drives the bolt blind to the bolted position when the inner handle moves to the intermediate position, and drives the hook bolt to the hookless position when the inner handle moves to the lower position. In the preferred design of the interactive interconnected lock independently, the inner handle drives the blind bolt from the boltless to the bolted position as the inner handle moves from the upper position to the intermediate position and the inner handle drives the hook bolt from the hooked position to the hookless position as the inner handle moves from the intermediate position to the lower position. An aspect of the invention is that the interlocking mechanism disconnects the hook bolt lock mechanism from the blind bolt lock mechanism when the inner handle moves to the upper position. Thus, manipulation of the hook bolt lock mechanism from the outside to move the hook bolt to the hookless position does not move the blind bolt to the boltless position. Another aspect of the invention is that the inner handle and the outer handle are rotated in different axes of rotation. The axis of rotation of the outer handle is through the first hole and the axis of rotation of the inner handle is located between the first and second holes, corresponding to the positions of the. Hook bolt and blind bolt mechanisms. In the most preferred embodiment of the invention, the interconnection mechanism includes two blind bolt impellers, which may be blind bolt gears. The two blind bolt impellers deviate from the axis of rotation of the outer handle by distances corresponding to two non-parallel distances of the hole normal in the industry to install separate hook bolt locks and blind bolt locks. This allows the lock to be used with existing installations, pre-drilled doors and patterns and tools to drill doors at any of the normal deviation distances in the industry. In the preferred design of the invention the inner handle drives a handle gear which is a partial gear. The handle engagement engages at least one blind bolt engagement as the inner handle moves from the upper position to the intermediate position to drive the blind bolt from the bolted position to the boltless position. The handle gear does not drive the blind bolt engagement as the inner handle moves from the intermediate position to the lower position. A retraction spring acts to apply a reengagement force of the blind gear and the partial handle gear as the inner handle moves through the intermediate position as it moves from the lower position to the upper position. The dead bolt engagement drives two secondary blind bolt gears preferably via an intermediate blind bolt engagement. The two secondary blind bolt gears form two alternative blind bolt impellers deflected from one axis of rotation of the outer handle by distances that correspond to two non-parallel distances of the normal hole in the industry. In order to urge the hook bolt lock mechanism independently of the blind bolt lock mechanism, the inner handle urges a first hook bolt lever with loss of movement from an extended hook bolt position to a retracted position of the bolt. hook bolt. The inner handle does not drive the first hook bolt lever as the inner handle moves from the upper position to the intermediate position during the loss of movement interval. The inner handle begins to drive the first hook bolt lever to retract the hook bolt as the inner handle moves from the intermediate position to the lower position. The hook bolt lever drives the sliding plate of the hook bolt vertically. The sliding plate of the hook bolt, in turn, drives a second hook bolt lever connected to a hook bolt hub, which engages to urge the hook bolt locking mechanism and retracts the hook bolt. To reduce friction between the first hook bolt lever and the hook bolt sliding plate, the sliding plate of the hook bolt includes a roller at the contact point between the first hook bolt lever and the sliding plate of the hook bolt. The sliding plate of the hook bolt preferably engages the second hook bolt lever with a rotary bearing having a sliding plate channel formed therein. The rotating bearing rotates in the sliding plate of the hook bolt and the second hook bolt sliding slides in the channel of the sliding plate of the rotary bearing. In an alternative embodiment of the invention, the handle gear interferes with the hook bolt hub when the inner handle is in the upper position to prevent the outer handle from rotating when the inner handle is in the upper position and the bolt extends. blind. The invention is also directed to a perforated lock interconnect mechanism for driving a hook bolt lock mechanism in a first hole in a door and a blind bolt lock mechanism in a second hole in the door. The interconnection mechanism includes a handle gear rotated by a movable inner handle between a top position, an intermediate position and a bottom position. At least one blind bolt gear is engaged to drive the blind bolt lock mechanism between bolted or unbolted positions.

The blind bolt gear is driven by the handle gear as the inner handle moves between the vertical position and the intermediate position and is not driven by the handle gear as the inner handle moves between the intermediate position and the lower position. A hook bolt hub is connected to drive the hook bolt lock mechanism between hooked and unhooked positions. The hook bolt hub is driven by the handle gear with loss of movement so that the hook bolt hub is not driven by the handle gear as the inner handle moves between the upper position and the intermediate position and the hook bolt hub is driven by the handle gear as the inner handle moves between the intermediate position to the lower position.

BRIEF DESCRIPTION OF THE DRAWINGS The aspects of the invention that are thought to be novel and the characteristic elements of the invention are exhibited with particularity in the appended claims. The figures are for illustration purposes only they are not drawn to scale. However, the same invention, both for organization and method of operation, can be better understood by reference to the following detailed description taken in conjunction with the accompanying drawings in which: Fig. 1 is a right side elevational view of an interconnected lock according to the present invention showing the lock installed in a portion of a door. The view is from the edge of the door and shows that the inner handle on the left rotates on a different axis from the outer handle on the right. The inner handle is shown in the upper position, indicating that the interlocked lock is with hook and bolt. Fig. La is a view in right lateral elevation of an interconnected lock according to the prior art showing the lock installed in a portion of a door. The view is from the edge of the door and shows that the inner handle on the left rotates on the same axis as the outer handle on the right. Also shown is the rotatable butterfly piece required for an interconnected lock of the prior art. Fig. 2 is a front elevation view of the lock interconnected in Fig. 1 showing the lock interconnected from inside the door. The inner handle is in the upper position as in Fig. 1 and it can be seen that the blind bolt and the hook bolt extend both, indicating that the interconnected lock is with hook and bolt.

Fig. 3 is also a front elevational view of the interconnected lock as in Fig. 2 except that the lock is shown with the inner handle in the intermediate position where the hook bolt extends and the blind bolt retracts. Fig. 4 shows the same view as Figs. 2 and 3 except that the lock is shown with the inner handle in the lower position when the hook bolt and the blind bolt are retracted so that the door can be opened. Figs. 5-7 show the interconnection mechanism within the interconnected lock of Figs. 1-4. The interconnection mechanism is below a cover or sheet that can be seen in Fig. 1 on the inner side of the door.

Fig. 8 illustrates the interconnection mechanism in the hooked and bolted position corresponding to Figs. 2 and 5 when the inner handle is in the vertical position with the blind bolt and hook bolt extended.

MODES FOR CARRYING OUT THE INVENTION To describe the preferred embodiment of the present invention, reference will be made herein to FIGS. 1-8 of the drawings in which similar numbers refer to similar aspects of the invention.

With reference to Figs. 1-4, the present invention includes an interconnection mechanism 10 having an internal handle 12 which drives a hook bolt lock mechanism 14 and a blind bolt lock mechanism 16. The interconnect mechanism 10 is installed inside 18 of the door 20. The hook bolt lock mechanism 14 includes an outer handle 22 and an outer portion 24 mounted on the external surface 26 of the door 20. The hook bolt lock mechanism 14 is a substantially perforated lock conventional, such as a cylindrical lock or tubular lock, including a conventional lock core (not shown) installed in a first hole 28 (see Fig. 29 extending perpendicularly from the inner surface 18 of the door 20 to the outer surface 26. The axis of the hole 28 is aligned with the axis of rotation of the outer handle 22. The hook-bolt lock mechanism 14 operates a hook bolt installed with conventionally 30. The blind bolt lock mechanism 16 includes a key operated external portion 32 that is conventionally installed in a second hole 34 (see Fig. 2) and a blind bolt 36. Fig. 1 shows an installation of the art. previous one of an interconnection mechanism 10 'what operates a blind bolt lock mechanism 16 and a hook bolt lock mechanism 14. It can be seen that the interconnected lock of this invention and an interconnected lock of the prior art appear from the inside as a blind bolt 16 and a hook bolt 14 installed separately conventional. The outer portions of the blind bolt and hook bolt lock mechanisms, as well as the blind bolt and hook bolt itself are the same in Figures 1 and 1 and are of conventional design as are used in separate installations as well as designs of Interconnected lock. However, inside the door, the present invention, as seen in Fig. 1, provides an interconnection mechanism 10 and an associated inner handle 12 which differs significantly from the interconnection mechanism 10 'and inner handle 12' of the prior art design observed in Fig. la. Specifically, the present invention omits the inner butterfly rotating part 13 of FIG. 1 and moves the inner handle 12 to a rotational axis different from the outer handle 22 and the inner handle 12 'of the prior art. In the interconnected locks of the prior art, as exemplified in Fig. 1, the inner handle 12 'and the outer handle 22 rotate about the same axis. However, as can be seen in Fig. 1, in the present invention, the inner handle 12 rotates on a shaft separated from the outer handle. The inner handle 12 of the present invention rotates on an axis that is located between the axes of the first and second holes 28, 34. As will be described in detail below, placing the inner handle on an axis different from the rest of the lock mechanism independently of hook bolt 14 and outer handle 22, it is possible to operate a bolt lock mechanism and blind bolt lock mechanisms independently, allowing them to act as required. This independent operation improves the safety by uncoupling the inner handle 12 and the blind bolt lock mechanism 16 of the outer handle 22 and the hook bolt lock mechanism 14. The blind bolt is isolated from the internal components of the lock mechanisms of hook bolt and groove 80 (see Figs 5-7) used to rotate the internal spindle of the hook bolt lock mechanism. Even if the outer handle 22 is separated or removed, and even if the internal components of the hook bolt lock mechanism are manipulated from the outside to retract the hook bolt, the decoupling design of the present invention prevents the blind bolt retract simultaneously with the hook bolt.

Figures 2-4 show the interconnected lock of the present invention in three different stages corresponding to 1) with bolt and with hook, 2) without bolt and with hook and 3) open. More specifically, in Fig. 2, the inner handle 12 is rotated to an upper position 40. In the upper position 40 of the blind bolt 36 and the hook bolt 3) both extend (closed and hooked) and the door closes. In Fig. 3, the inner handle 12 has been rotated from the upper position 40 to the intermediate position 42. As the handle moves between these two positions, the blind bolt 36 retracts (without bolt). When the lower handle 12 fully reaches the intermediate position 42, the blind bolt 36 has completely retracted into the door. As the handle continues to move from the intermediate position 42 to the lower position 44, the hook bolt 30 is retracted. As can be seen in Fig. 4, with the handle 12 in the completely lower position, the hook bolt 3 it retracts completely and the door is released to open. As the inner handle moves between the upper position 40 and the intermediate position 42, the blind bolt moves between the bolted and unbolted positions. In deference to the interconnected locks of the prior art, as in Fig. La, the inner handle 12 also it can be used to extend the blind bolt. Consequently, a rotating butterfly piece 13 inside the door is not required to extend the blind bolt. This greatly simplifies the operation of the lock since it is not necessary to operate a separate rotating wing piece to extend the blind bolt. In addition to improving safety, the design of this invention decreases the maximum torque required to operate the lock mechanism. Because the retraction of blind bolt and lock bolt occur in different sectors of the inner handle rotation, at no point is it necessary to simultaneously drive the blind bolt and lock bolt. The torque required to operate the handle as it moves from the upper position 40 to the intermediate position 42 depends solely on the friction and spring pressure required to operate the blind bolt lock mechanism. The torque required to rotate the inner handle from the intermediate position 42 to the lower position 44 depends solely on the design of the hook bolt lock mechanism. Consequently, unlike the prior art which simultaneously retracts the blind bolt and the hook bolt, the interconnected lock of the present invention does not increase the torque required to operate the bolt. lock above what is required for a blind bolt lock mechanism or separate hook bolt. In addition to the safety advantage, the advantage of simplified blind bolt extension and the advantage of reduced torque, the present invention makes it easier to verify that the door is closed. Those who have low vision, and those who are far from the door can easily see if the door is properly closed by simply referring to the position of the interior handle. The details of the interconnection mechanism 10 are shown in Figs. 5-7, which illustrate the components of the interconnection mechanism and their relative positions in the three positions shown in Figs. 2-4. Fig. 5 corresponds to Fig. 2 with the blind bolt 36 in the bolted position and the hook bolt 30 in the hooked position. Fig. 6 corresponds to Fig. 3 with the blind bolt retracted (without bolt) and the extended hook bolt (with hook) with the inner handle in the intermediate position. Fig. 7 corresponds to Fig. 4 with the blind bolt and the retracted hook bolt (without bolt and without hook) and the inner handle 12 in the lower position. The interconnection mechanism in Figs. 5-7 includes a series of gears mounted on a reinforcing plate 50. An identical faceplate has been removed to show the placement of the internal components. The plate The reinforcement and the faceplate contain the internal components sandwiched between them and act as bearings to maintain necessary arrows for the gears shown. The complete interconnection assembly is mounted on the inner surface 18 of the door 20 and covered by a decorative cover or sheet as seen in Figs. 2-4. Referring to Fig. 5, the interconnection mechanism includes a handle gear 52 which is a partial gear having teeth along a first sector of approximately 90 ° and a uniform toothless perimeter on the rest of the gear. The handle gear 52 is driven every time by the inner handle 12 and moves with the handle as can be seen by comparing the position of said gear in Figs. 5, 6 and 7 with the corresponding position of the handle in Figs. 2, 3 and 4. The gear of the handle 52 drives a blind bolt gear train as long as the gear portion engages the gear train, but does not drive the blind bolt gear train when the uniform sector reaches the point of contact with gear with the bolt gear of blind bolt. The blind bolt gear train is comprised of a primary blind bolt gear 54, an intermediate blind bolt gear 56, mounted on the same shaft as the primary blind bolt gear, and a pair of gear bolts. secondary blind bolt 58, 60 lying above and below the primary and intermediate blind bolt gears. As the inner handle 12 moves from the upper position in Fig. 5 to the intermediate position in Fig. 6, the handle gear 52 rotates and drives the blind bolt gear 54. The primary blind bolt gear also is a partial gear and stops rotating when the uniform toothless portion of the handle gear 52 reaches the point or contact with the primary blind bolt gear 54. As the inner handle moves from above to the level, FIG. 5 to Fig. 6, the primary blind bolt gear and the intermediate blind bolt gear 56 rotate. The rotation of the intermediate blind bolt gear 56 drives the secondary blind bolt gears 58, 60. The two secondary blind bolt gears are located on the arrows that deviate two different distances from the axis of rotation of the external handle to 62. Non-parallel distances correspond to normal non-parallel distances in the industry between the first hole for the hook bolt lock mechanism and the second hole for the blind bolt lock mechanism. The design allows the interactive mechanism to be installed with any of the two non-parallel deviations between the blind bolt and the hook bolt and allows the use of normal patterns and accessories. The interconnected lock it can be used in pre-existing installations with preexisting normal non-parallel holes for the blind bolt and bolt. Consequently, the external portion of the blind bolt lock mechanism will be axially aligned with the axis of rotation of the secondary blind bolt gear 58 or blind bolt gear 60. The groove in the center of the shaft of the blind bolt gear 58 or gear of the bolt 58 blind bolt 60 receives an arrow from the blind bolt lock mechanism. The blind bolt gear train rotation as the inner handle moves between the middle and upper positions will drive the blind bolt between bolted and boltless positions. Raising the inner handle extends the blind bolt and decreasing the handle retracts it. The uniform segment portion of the handle gear 52 and the partial gear design of the primary blind bolt gear 54 ensures that the rotation of the inner handle between the intermediate position and the lower position has no effect on the blind bolt lock mechanism . Because the primary blind bolt gear 54 decouples the handle gear 52 as the uniform portion of the handle gear reaches the contact point, a spring 64 is provided. As can be seen in Fig. 5, the spring Reattachment comprises an arm of a spring arm. The spring arm comes into contact with a primary blind pin engagement pin 54 just as the gear disengages from the tooth sector of the handle gear 52 and is in the spring loaded contact with the uniform non-toothed sector of the handle gear. The engagement spring 64 provides a rotational torque to the primary blind bolt engagement to ensure that the first tooth in the partial portion of the primary dead bolt engagement 54 is properly reattached to the first tooth in the toothed sector of the handle engagement 52. as the internal handle is rotated from below the intermediate position after the intermediate position towards the upper position. During the operation of the blind bolt lock mechanism described above, the hook bolt is not affected. To operate the hook bolt lock mechanism a first hook bolt lever 66 is mounted to freely rotate on the same axle as the handle gear 52. The handle large 52 drives the first hook bolt lever 16 with a lost motion interaction so that rotating the handle gear 52 from the position in Fig. 5 (inner top handle) to the position in Fig. 6 (middle position) has no effect on the first hook lever 66 As can be seen by comparing Figures 5 and 6, the handle gear 52 has been rotated, but the first hook bolt 66 has not moved.

However, as the handle gear reaches the position in FIG. 6, a protruding portion of the hub 69 of the handle gear 52 contacts the first hook bolt 66 at the point marked with the handle. reference number 70. At this point the first hook bolt lever 66 begins to rotate with the handle gear. The first hook bolt lever 66 rotates from the position in Fig. 6 (extended hook bolt) to the position observed in Fig. 7 (retracted hook bolt). The range of motion lost from Fig. 5 to Fig. 6 ensures that the engagement of the handle does not drive the hook bolt when the inner handle moves from the upper position to the intermediate position. As the inner handle moves past the intermediate opposition to the lower position, and the first hook bolt lever moves from the extended position of the hook bolt in Fig. 6, to the retracted position of the bolt of the hook bolt. In FIG. 7, the first hook bolt lever drives a sliding plate of the hook bolt 72. The sliding plate of the hook bolt moves vertically in the slot 74. The hook bolt slide plate 72 is provided with a roller 76 for reducing friction between the hook bolt lever 66 and the slide plate 72.

The hook bolt plate 72 drives a second hook bolt lever 78, which rotates a hook bolt hub 80. The hook bolt hub 80 includes a slot 82 and an ear 84 which engages and drives the hook mechanism. Hook bolt lock to retract the hook bolt as the inner handle moves from the intermediate position to the lower position. The sliding plate of the hook bolt 72 drives the second hook bolt lever 789 with a rotary bearing 86 having a sliding plate channel 88 formed therein. As the sliding plate moves downward, the distance between the axis of rotation 62 of the outer handle and the bearing 86 changes. The second hook bolt lever slides axially in the sliding plate channel 88 of the rotary bearing 86 to adapt this shift distance. This design provides a solid feel to the interconnected lock while simultaneously reducing friction. The hook bolt hub 80 is urged to bring the hook bolt slide plate 72 back into its initial position with the spring 90, which also urges the inner handle back into the intermediate position. Fig. 8 is substantially identical to Fig. 5, except that it shows a modified version of the hook-pin hub 80. This modification is used with mechanisms of hook bolt lock provided with a passage function in which the internal and external screws of the hook bolt lock are directly connected together. In an alternative design shown in FIG. 8, the bolt-bolt hub 80 is provided with a protruding detent 100 that contacts the handle gear at 102. When the inner handle is in the upper position, as shown in FIG. illustrated in FIG. 8, the handle gear portion 102 prevents the projection 100 from rotating in the hub of the hook bolt 80. This prevents the internal spindle of the hook bolt lock mechanism from turning. When the used hook bolt lock mechanism has the internal and external spindles directly bonded (passage function) it closes the external handle against movement when the inner handle is in the upper part. As can be seen by comparing Figures 6 and 7, as soon as the inner handle is turned towards the intermediate or lower position, the handle gear is disengaged from the hook bolt hub 80 and the operation is identical to the operation described. before. It will be seen from the above description that the objects of this invention have been achieved. The blind bolt lock mechanism and the hook bolt lock mechanism operate independently, still interacting as desired for an interconnected lock.

The safety has been improved, the torque of the handle has been reduced compared to the interconnected locks of the prior art, and the blind bolt extension has been simplified, allowing the removal of the rotating wing piece from the locks of the bolt. previous technique. Finally, the state of the lock can be easily determined by visual inspection of the position of the inner handle. While the present invention has been particularly described in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in view of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations that fall within the scope and spirit of the present invention. Therefore, having described the invention, what is claimed is:
