The cam (20) rotates with the lock plug (111), while the motion control sleeve (40) is stationary. The cam (20) has at least one cam slot, and the motion control sleeve (40) has at least one motion control slot. A shaft (50) extends outward from the housing and has at least one projection which is engaged with both the cam slot and the motion control slot. The cam slot and the motion control slot are configured such that rotation of the lock plug imparts a sequence of rotational and axial movements to the shaft (50). A latching member (70) attached to the shaft, moves between a latched position and an unlatched position in a sequence of axial and rotational motions in order to selectively secure a door, panel, or the like in the closed position.

Description

LOCK OPERATED BY KEY WITH COMBINED ACTION ROTATION AND TRANSFER ACTION TECHNICAL FIELD The present invention relates generally to fastening devices and more particularly to fastening devices, for fastening a first member such as a door, panel or the like in a closed position with respect to a second member such as a door, panel or corresponding frame. PREVIOUS TECHNIQUE Various types of ironing devices are known for use in securing a first closure member such as a door, panel or the like in a closed position with respect to a single corresponding closure member such as a door, panel or frame. Some types incorporate a similar ratchet or member, which is actuated to engage a locking member for fastening. In particular, bolts operating to move the locking member both rotationally and translationally have been proposed to engage a locking member for locking. For example, U.S. Pat. No. 5,165,738 issued to Edwards McCormak on November 24, 1992, U.S. Pat. No. 4,878,367 issued to Robert H. Bisbing on November 7, 1989, US Pat. No. 4,583,775 issued to Robert H. Bisbing on April 22, 1986 and US Pat. No. 4,556,244 issued to Robert H. Bisbing on December 3, 1985, all showing locking mechanisms with a combined action of rotational and translational locking. However, none of the references cited previously illustrate or suggest the unique structural features of the key-operated bolt of the present invention. DESCRIPTION OF THE INVENTION The present invention is generally directed to a key operated lock for use with a door, panel or the like. The bolt includes a housing having a bore, a first end and a second end. A lock plug, a lock plug sleeve, a movement control sleeve and a sleeve type cam are received within the bore of the housing. The lock plug sleeve and the motion control sleeve are supported within the housing such that they are stationary with respect to the housing. The lock plug is placed coaxially with the lock plug sleeve and is selectively rotationally movable relative to the lock plug sleeve when using a key. The sleeve-type cam engages the lock plug such that it rotates with the lock plug. The sleeve-type cam has at least one cam groove and the movement control sleeve has at least one groove for movement control. The bolt further includes an arrow that is positioned at least in part within the housing, with a portion of the arrow extending outward from the second end of the housing. The arrow has at least one projection that engages both the cam slot and the motion control slot. The cam slot and the motion control slot are configured such that rotation of the lock plug imparts movement in the arrow which is a sequence of movements including rotational movement and axial movement. A bolting member is supported by the arrow outside the housing, such that the bolting member and the arrow move as a unit. In this way, the locking member moves between a locked position and a released position in a sequence of axial and rotational movements in order to selectively and releasably hold the door, panel or the like in the closed position. Accordingly, an object of the present invention is to provide a bolt operated by novel key. Another object of the present invention is to provide a novel latch of the type that incorporates a ratchet or similar member and which is actuated through the operation of the key. Still another objective of the present invention is to provide a bolt operated by novel key, wherein the ratchet moves both rotationally and axially. Still another object of the present invention is to provide a novel latch that applies a compressive force between first and second closure members. These and other objects of the present invention will be more readily apparent when taken into consideration with the following description and the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is directed to a key operated lock that it has wide application and can be used with a wide variety of closure members such as a door or the like, to releasably hold a closure member in the closed position. One embodiment of a bolt according to the present invention is illustrated in the Figures. The particular bolt illustrated in the present embodiment is similar in many respects to a bolt shown, described and claimed in US Pat. No. 4,583,775 (Patent * 775) entitled "Latch assembly having pull-up action" (bolt structure having extraction action) which is incorporated by reference herein. For reasons of brevity, emphasis will be made in the following description to the characteristics in the present modality that differ from that established in the '775 Patent. As illustrated in the Figures, the bolt structure 10 according to the present includes, as its portions, a housing 30, an arrow 50 having an end 54, fastening means comprising in this embodiment a latch ratchet 70. mounted on the threaded end of the arrow 50 by mounting nuts 71, and driving means comprising in this mode, a sleeve-type cam 20, a motion control sleeve 40, a transverse pin 60, a lock plug 111, a lock plug sleeve 113, a bushing 115, a retaining ring 117 and a key 119, the details of which will be described below. In the present embodiment, the locking pawl 70 is rotationally movable by the arrow 50 and is also movable by the arrow 50, axially in the longitudinal direction of the arrow. In operation, the bolt structure 10 is mounted in an opening through a member, such as a closure member, and the pawl is moved to engage a second member, such as a corresponding frame. To fasten the closing member to the frame, the locking ratchet 70 is first rotated to a position such that it is in line with the frame member. The locking ratchet 70 then moves longitudinally, such that it engages the edge of the frame. The arrow 50 moves rotationally and also longitudinally by the driving means. The lock plug 111 is generally cylindrical and in the nature of a conventional lock plug, it includes an opening for key access in a set of wafers or platelets that are retracted when the key 119 is inserted. The lock plug sleeve 113 is also generally it is cylindrical and includes a bore 18, generally cylindrical in configuration and receiving the lock plug 111. The bushing 115 comprises a generally annular member in this embodiment, including the through opening 130 and operates to retain the internal components, including the valve plug. lock 111, lock plug sleeve 113, sleeve type cam 20, movement control sleeve 40 and transverse pin 60. Retaining ring 117 is also a generally annular member and operates to support the anterior components of the arms. means of the drive within the housing 30. The housing 30 in the present embodiment is a compose generally elongated having a first end, a second end, a bore extending longitudinally through the housing 30 and an outer surface. The second end 32 of the housing 30 has a central opening, contiguous with the bore of the housing 30, through which the arrow 50 passes. As used herein, the distal end of a component part refers to that end of the housing. component door which is located furthest from the first end of the housing 30, when the bolt 10 is fully assembled, while the proximal end of a part of the component is the end closest to the first end of the housing 30, again when the bolt 10 It is fully assembled. In the present embodiment, the distal ends of the movement control sleeve 40 and the sleeve cam 20 abut against the end wall surrounding the central opening at the second end 32 of the housing 30. The lock plug 111 and the Lock plug sleeve 113 are positioned within the bore of the housing 30 adjacent the first end 33 of the housing 30. The outer surface of the housing 30 includes a first flanged portion 35 adjacent the first end 33. The outer surface of the housing 30 also includes a second portion 37. The second portion 37 of the housing 30 is provided with interrupted threads on a portion of its outer surface. The threads on the outer surface of the second portion 37 of the housing 30 are interrupted by four planes formed on the outer surface of the housing 30. The planes formed on the outer surface of the housing 30 prevent rotation of the housing 30 when the key 119 is used to rotate the lock shutter 111, once the lock 10 is installed in a closing member such as a door or the door frame. The interrupted threads on the outer surface of the housing 30 are engaged by a nut to hold the bolt 10 in place, once the bolt 10 is installed in a closing member such as a door or the door frame. In the present embodiment, the lock plug 111 is rotatable within the housing 30 and prevented from moving in the axial direction, i.e. over the longitudinal axis of the housing 30, by the retaining ring 117. The retaining ring 117 receives inside the slots 13 and 161, which are located in the hub 115 and the housing 30, respectively and are in register with each other. As a result, the bushing 115 and the retaining ring 117 rotate as the lock shutter 111 rotates., means are provided between the lock plug 111 and the cam 20, to allow rotation of the cam 20 before rotation of the lock plug 111. In the illustrated embodiment, the distal end of the lock plug 111 is provided with a pair of notches 16 receiving ears 21 projecting axially from the proximal end of the cam 20. From this variety, when the lock plug 111 is rotated, such as by the key 119, the sleeve cam 20 is also rotated. The sleeve-type cam 20 is provided with at least one and in the present embodiment, a pair of cam slots 25 spaced 180 ° circumferentially. Each of the slots 25 runs in a direction that has both circumferential and axial components. The lock plug sleeve 113 in this embodiment is received in the housing 30 in a substantially fixed rotational position. As illustrated, the lock plug 111 is substantially enclosed by the lock plug sleeve 113, which operates to substantially center the lock plug 113 within the opening in the housing 30. In addition, means are provided between the plug sleeve lock 113 and lock plug 111, to provide locked and released conditions of bolt structure 10. In this embodiment, lock plug sleeve 113 includes a groove 150 on its interior surface, which cooperates with the sealing wafers of lock 111, in order to provide the latched and released conditions of the bolt structure 10. In particular, in this embodiment, the wafers of the lock bolt 111, extend when the key 119 is removed and in this way, the rotation of the Lock plug 111 is prevented when the wafers are received in slot 150 of sleeve 113. Wafers of lock plug 111 are retracted away from the slot 150 in the lock plug sleeve 113 by the insertion of the key 119 that allows subsequent rotation of the lock plug 111 with respect to the lock plug sleeve 113. Installed coaxially between the housing 30 and the sleeve type cam 20, there is a movement control sleeve 40, which has a pair of motion control slots. Each movement control slot has an axial slot portion 41 and a circumferential slot portion 42. Each of the axial portions 41 extends in a direction parallel to the longitudinal axis of the housing 30, and each of the circumferential slot portions. 42 extends over an arc length of a circle formed in a plane perpendicular to the longitudinal axis of the housing 30, with the structure of the bolt 10 in the fully assembled configuration. In the present embodiment, the motion control slots are 180 ° apart from each other. The end of each axial groove portion 41, located distally of the first end of the housing 30, connects to one end of a respective one of the circumferential grooves 42. The bolt structure 10 further includes means for substantially preventing rotation of the movement control sleeve 40 with respect to the housing 30. In this embodiment, the sleeve 40 includes two notches 152 at its lower end and resting on two tabs 160 inside the bottom of the housing 30. The structure of the bolt 10 also includes means between the control sleeve of movement 40 and the lock plug sleeve 113, to substantially prevent rotation of the lock plug sleeve 113 relative to the housing 30. In this embodiment, the sleeve 40 includes a pair of notches 44 at its upper end and which receive ears 140. which project axially from the distal end of the lock plug sleeve 113. The motion control sleeve The fixed part 40 can also be provided integral with the housing 30, which is formed directly within or extends from an interior surface of the housing 30. The slot portions 41, 42 in the movement control sleeve 40 function respectively as rotational motion control slots and as axial movement control slots. The arrow 50 is elongated and projects outwardly from the second end of the housing 30 as it passes through the central hole in the second end 32 of the housing 30. The arrow 50 is held such that the longitudinal axis of the arrow 50 matches with the longitudinal axes of the housing 30, the movement control sleeve 40 and the cam 20. At least the majority of the portion of the arrow 50 that is outside the housing 30 is provided with interrupted threads. The threads of the arrow 50 are interrupted by a pair of planes machined on either side of at least the threaded portion of the arrow 50. The threaded portion of the arrow 50 fits through a hole in a ratchet end 70. The hole at the ratchet end 70 it has flat sides corresponding to the planes on both sides of the arrow 50. In this way, relative rotation movement between the pawl 70 and the arrow 50 is prevented, and the pawl 70 and the arrow 50 rotate with respect to the longitudinal axis of the arrow 50 as a unit. The threads interrupted in the arrow 50 are engaged by the mounting nuts 71 so as to hold the pawl 70 in place at a desired location over the length of the threaded portion of the arrow 50. The relative positions of the movement control sleeve 40 and cam 20, can be reversed. That is, the movement control sleeve 40 can be inside the cam 20 instead of outside, as illustrated. Mounted on arrow 50 is transverse pin 60 which projects laterally from opposite sides of arrow 50 and functions as both a cam follower and a motion control pin. The transverse pin 60 cooperates with the cam 20 and the movement control sleeve 40, to control, if in response rotation of the lock plug 111, the arrow 50 and the ratchet 70 move only axially or rotationally only. This is determined if the opposite ends of the pin 60 are placed through the axial slot portions 41 or through the circumferential slot portions 42.

The housing 30 is mounted on the closure member by retaining means which, in the present embodiment, are constituted by a washer and a mounting nut which engages the threads on the outer surface of the housing 30. In the present embodiment, the housing 30 it is installed in a closure member when placing the bolt assembly 10, such that the housing 30 extends through an opening that passes through the closure member. The bolt structure 10 is installed in such a way that the first end of the housing 30 is accessible by a user to insert the key 119. The installation of the bolt structure 10 is more easily achieved when the pawl 70 is not mounted on the latch. arrow 50, such that arrow 50 can first be inserted through the opening in the closure member. The pawl 70 can then be mounted on the arrow 50 after the housing 30 is positioned to extend through the opening formed in the closure member, however, this sequence of steps for the installation of the bolt structure 10 is not a requirement The housing 30 is then held within the opening of the closure member by the mounting nut and if the washer is also desired. In the present embodiment, the components of the bolt structure 10 are preferably made of metal and metal alloy materials, however other suitable materials may also be used when desired. Furthermore, in the present embodiment, the closure member may be constituted by any suitable materials such as wood or metal and may be of varying thickness. The operation of the bolt when installed as part of a structure including a closing member will now be described. When the lock plug 111 is rotated, such as by the key 119, the sleeve cam 20 will move to rotate in the same direction as the lock plug 111. When the cam 20 is rotated, the transverse pin 60 moves, but that the movement be axial or rotational, depends on whether the ends of the pin 60 are in the axial groove portions or in the circumferential groove portions of the movement control sleeve 40. When in the locked position, the lock plug 111 is in its fully clockwise position, and the two opposite ends of the transverse pin 60 are positioned through the axial slot portions 41 of the motion control sleeve 40, near the ends of the portions. of axial groove 41, which are closer to the first end of the housing 30. In addition, the portions of the transverse pin 60 projecting from either side of the arrow 50, mate simu At the same time the cam grooves 25 of the cam 20. At the end of the clockwise rotation of the lock plug 111, the projecting portions of the transverse pin 60 are placed closer to the ends of the cam grooves. 25 which are closer to the proximal end of the cam 20. The pitch of each of the cam grooves 25 is such that the axial distance, ie the distance measured in a direction parallel to the longitudinal axis of the cam 20, between a place on the cam groove 25 and the proximal end of the cam 20, increases in the clockwise direction, starting at the end of the cam groove closer to the proximal end of the cam 20. For releasing the closure member for example from the cabinet frame, the lock shutter 111 is rotated in a counterclockwise direction. When this is done, the lock plug 111 and the cam rotate as a unit. The transverse pin 60 can not move rotationally because its opposite ends are within the axial slot portions 41 of the stationary motion control sleeve 40. As a result, when the cam 20 is rotated in the counterclockwise direction, the opposite ends 13 of the pin 60 follow the opposite cam grooves 25 and as a result, the pin 60 and therefore also the arrow 50 and the ratchet of the bolt 70, will move away from the first end of the housing 30 in a direction parallel to the longitudinal axis of the arrow 50. The axial movement of the arrow 50 and the pawl 70, away from the first end of the housing 30 and away from the member frame of closure, continues until the ends of the pin 60 reach the circumferential groove portions 42. After the lock plug 111 and the cam 20 have been rotated as a unit by approximately 120 °, the transverse pin 60 has moved axially away from the proximal end of the movement control sleeve 40 and is now aligned with the opposite circumferential slot portions 42. Additional rotation of the lock plug 111 and the cam 20 now causes rotational movement of the transverse pin 20, arrow 50 and ratchet 70, as the ends of the pin 60 move over the opposite circumferential slot portions 42. In this manner, the pawl 70 moves out of alignment with the frame member and after approximately 60 ° of rotation, the closing member or the door is completely released. The lock plug 111 has now been rotated approximately 180 ° from its fully locked position. The locking action is simply the inverse of the liberation action just described. When locking, as the lock plug 111 is rotated clockwise, the opposite ends of the transverse pin 60 move in the clockwise direction over the circumferential slot portions 42 and arrow 50 rotates in the direction clockwise about its longitudinal axis. Then, the transverse pin 60 moves axially towards the proximal end of the movement control sleeve 40, when the transverse pin 60 reaches the axial slot portions 41. These sequential movements are caused by the walls 22 of the cam slots 25, which move the ends of the transverse pin 60 over the circumferential groove portions 42 in the clockwise direction, until the ends of the transverse pin 60 buttress against the edge of the axial slot portions 41. Subsequently , the walls 42 of the cam grooves 25 move the ends of the transverse pin 60 axially towards the proximal end of the movement control sleeve 40 over the axial slot portions 41. In this manner, the cam 20 and the control sleeve movement 40 causes cooperatively the rotational and axial movements of the arrow 50 to be carried out in sequence, in response to movement rotational movement of the lock plug 111 in the locking direction or in the clockwise direction in a continuous movement. The new bolt structure has been described as mounted on a movable door. This is the preferred location. However, a bolt incorporating the basic concept in the present invention can be mounted in the fixed cabinet instead of the door. In this case, the arrow and ratchet of the bolt will rotationally move to engage a latch mounted on the inside of the door and then axially away from the first end of the housing 30 to urge the door to the closed position tightly. This is the inverse of the axial movement used to close the door tightly, when the bolt is mounted on the door. When the bolt 10 is used in this mode, the closing member will lock in the counterclockwise direction and turn in the clockwise direction. The locking and unlocking directions of the bolt 10 can be reversed by simply reversing the pitch of the cam grooves 25 of the direction in which the axial groove portions 41 extend relative to the circumferential groove portions 42. The directions in the clockwise and counterclockwise as used here, refers to the direction of rotation as perceived by an observer in front of the fixed keyway of the lock plug 111. It will be recognized by those skilled in the art that changes may be made to the above-described embodiments of the invention without departing from its concept. extensive inventiveness. It is understood, therefore, that the invention is not limited to the particular embodiments described, but is intended to cover all modifications that fall within the scope and spirit of the invention as defined by the appended claims. INDUSTRIAL APPLICABILITY The present invention is directed to a latch mechanism having a wide range of industrial applicability, in any part where it is required to releasably fasten a first closure member such as a door, panel or the like, with respect to a second latch member. closure such as a door, a panel, a compartment, a cabinet, a container, a frame or the like.
