The invention resides in the novel constructions and come binations and arrangements of the parts of the lock which accounts for its simplicity of construction and its reliability and ease of operation and further features and advantages will be herein rev-erred to or will become apparent to those skilled in the art to which the invention pertains from the following description of the preferred embodiment depicted in the accompanying drawings.
Figure 1 is a fragmentary, elevation Al view of a closed body highway truck having a lock embodying the present invention - Ed s assembled therewith;
Figure 2 is a fragmentary sectional view approximately on the line 2-2 of Figure 1 looking in the direction of the arrows;
Figure 3 is a fragmentary view partly in section and partly in elevation showing a modified lock embodying the present invention; and Figure 4 is a fragmentary view with parts broken away of the embodiment of Figure 3.
Although the closure control mechanism of the present invention designated generally by the reference character A, can be otherwise employed, it is herein depicted and described as connected to the inside of a - ye pivoted door B of a closed body highway truck, the body of which is designated generally by the reference char-cater C. the door B opens outwardly and is hinged at its left hand vertical side, as viewed in Figure l, to the truck body C. It is to be understood however, that the closure control mechanism A is equally apply-cable to either right or left hand doors. Closure control mechanisms of the type to which the invention no-fates are typically referred to in the trade to which it relates as a "lock' and the closure control motion is depicted in the drawings and herein described will lo be hereinafter sometimes referred to as a lock. The reference character G designates a soft gasket around the door opening in the truck body C against which the door B closes.
The closure control mechanism or lock A comprises top and bottom dead bolt assemblies D, E which are dupe ligates of one another and are connected to the inside of the door adjacent to its free vertical edge 12 and its non-pivoted upper and lower horizontal edges 14, 16 by headed and threaded fasteners indicated by the refer-once character 18. Since the bolt assemblies D, E reduplicates, only the upper assembly D will be herein described in detail and the duplicate parts of assembly E will be designated by the same reference characters with a prime mark affixed thereto.
The bolt assembly D includes a frame or bolt sup-porting bracket 20 comprising a base plate 22 and a channeled top or cover plate 24 equal in size to the plate 22, as viewed in elevation, connected together and to the door B by the fasteners 18. The plates 22, 24 form there between an aperture 26 in which a dead bolt 28 is slid ably supported with at least one end, which in the case of the bolt 28 is the upper end there-of, projecting from the bracket 20 in the direction of I
the adjacent horizontal edge of the door B. This upper end of the bolt 28 which is the end that engages a keeper or catch in the form of a plate 30 connected to the adjacent structure of the door opening of the truck body C, is bifurcated, providing two tines 34, 36 bet-wren which a roller 40 is rotatable supported on a pin 42. The end of the bolt 28 is tapered as at 44 on the side thereof facing in the direction of the door. The roller 40 extends slightly beyond the side of the member in which it is supported facing the inner side of the door and is the part of the bolt which engages the keeper or catch 30, except for the tapered end I of the member 28 there above, as the bolt is moved to a locking post-lion after the door is closed.
The lower end of the bolt 28, that is, the end facing in the direction away from the upper edge 14 of the door B, is also bifurcated, providing front and back tines 50, 52 between which the upper flattened end of a rod 54 for reciprocating the bolt 28 is pivoted on a headed and threaded fastener 56 the shank of which is threaded into a tapped aperture in the tine 52. The lower flattened end of the rod 54 is pivoted to an up-standing or forwardly extending stud or post 60 on a rotatable operating member 62 supported in a frame as-symbol 64 of a bolt operating structure or member design noted generally by the reference character F. The stud 60 is eccentrically located with respect to the axis of rotation of the member 62.
The frame assembly 64 comprises a back plate 66 and a channel-like front or cover member 68 providing an aperture between the members 66, 68 in which the member 62 is rotatable supported by suitable means in-eluding a boss 70 on the rear side (adjacent the door) of the member 62 which is rotatable received in a air-cuter aperture 72 in the plate 66. The stud or pivot pin 60 extends forwardly of the cover plate 68 and is provided with a roller where it projects past the cover plate 68. One side of the lower end of the rod 54 abuts an end of the roller 74 and a cotter pin 76 in the end of the stud 60 engages the other side of the rod to maintain it assembled with the stud 60.
The rotatable member 62 is provided with a driving connection in the form of a square through-aperture 78 concentric with its axis of rotation for the reception and disengagement of a manual tool for oscillating the same to extend and retract the bolt 28. The tool for oscillating the member 62 may include a handle fixed to the member 62, if desired. An aperture H in the door B
in alignment with the aperture 78 allows insertion of a tool such as the tool K for operation of the lock from the exterior of the vehicle. During oscillation of the member 62 the roller 74 rolls along an arcuate surface 80 on the side of the cover plate 68 which surface ton-minutes in reverse bends or arcs 82, I that limit the travel of the roller 74 and in turn the extent of move-mint of the bolt 28.
The rotatable member 62 is resiliently held or biased to whichever of its limited positions to which it is manually moved by a compression spring 90 on the shank of an eye member 92 the eye 94 of which engages about a short stud or projection 96 on the member 62 located at one side of the vertical centerline through the frame assembly 64 and through which centerline the axis of rotation of the member 62 passes. The free end of the shank of the eye member 92 projects through an aperture in lower forwardly extending part 98 of the 30 cover plate 68 the center of which aperture lies in the aforementioned centerline. The lower end of the spring abuts the part 98 of the cover plate 68 and the upper end abuts the member 62.
I
The lower bolt 28' is connected to the rotatable member I in the bolt operating assembly by a rod 54' similar to the rod 54 and connected to the bolt 28' and a second stud or projection 60' on the member 62 in a manner similar to that in which the rod 54 is connected to the bolt 28 and to the stud 60 and the corresponding parts being designated by the same reference characters with a prime mark affixed thereto.
The studs or projections 60, 60' are located 180 from one another about the axis of rotation of the mom-bier 62 from which axis they are offset eccentrically a distance to effect the desired movement of the bolts 28, 28' in their supporting brackets. In operation of the lock, the roller 741 on the stud 60' travels along an arcuate surface Blue similar to the surface 80 and at the ends of its travel abuts reverse arcs 82', 84' in a manner similar to that in which the roller 74 abuts the arcs 82, 84. As the door is closed and the member 62 rotated to secure the door in closed position, the in-dined ends 44, 44' first contact the striker plates 30, 30 1 and upon continuous rotation of the member 62 the rollers 40, 40l engage the plates and draw the door tightly closed compressing the gasket G. The plate-like keepers 30, 30 ' may be omitted if desired and the bolts 28, I allowed to engage directly parts of the truck body adjacent thereto. Alternately, one embody-mint of the invention utilizes tapered plates similarity plates 30, 30 I but that vary in thickness along their length, being relatively thin adjacent the door edge and thicker farther from the edge to form an incline so movement of the bolts into a locking position applies progressively more closing force as the rollers 40, 40' move up the inclines.
As another feature of the invention, the rotatable bolt actuating member 62 is further provided with a cam go type bolt in the form of an arm 110 projecting from one side thereof in the direction away from and normal to the vertical free edge of the door for engagement with a keeper or catch 112 in the form of a plate fixed to the truck body C when the bolts 23, 28' are engaged with their respective keepers or catches 30, 30'. The free end of the arm 11~ carries a roller sleeve 114 for engagement with the keeper 112 to facilitate its enrage-mint and disengagement thereof with the keeper. One end aye of the plate-like keeper 112 is inclined to provide a surface for -the roller sleeve 114 to roll up upon and pull the door closed.
The lock A of the invention is herein shown and described as applied to the inside of an outwardly open-in door B of a closed body highway truck, but it is equally applicable to various closure members even those that are not pivoted along one edge. The depicted lock, for example, can be applied to a door such as the door B but opening inwardly of the truck body by removing the bolts 28, 28' from their supporting brackets 20, 20l, rotating the bolts 180~ about their longitudinal axis and reassembling them with their supporting break-eta. This would necessitate providing either surface mounted or recessed keepers or catches having apertures for the reception of the ends of the bolt or bolts. In the event the center bolt 110 is employed, a suitable 25 keeper or catch would also be provided. Recessed keep-ens or catches are shown in United States Patent No.
3,333,878.
A second embodiment of the invention is shown in Figures 3 and 4 of the drawings, constructed to provide 30 handles 110, 112 on two opposite sides of a door L, the handle 110 being on the inside of a closed compartment of a vehicle and the handle 112 on the outside. This construction is useful on vehicles, such as tactical military vehicles, and allows a person within the vow-ale to selectively disable the outside handle 112 from inside of the vehicle so tile outside handle will not operate the bolts and will not prevent operation of the inside handle. Thus, if the outside handle is padlocked in place the bolts can nevertheless be operated with the inside handle.
A bolt operating assembly M is provided similar to the assembly F, but having a first rotatable member 114 similar to the member 62 but having a hub 116 extending from a larger diameter body portion 117. The member 114 is rotatable received in a frame assembly 120 semi-far to the frame assembly 64. The hub extends from the frame assembly into the vehicle and supports the inside handle 110, which is pinned to the hub. Rotation of the handle rotates the member 114 to actuate the bolts in the same manner as does the member 62.
The bolt assembly M also has a second rotatable member 122 that has a hub 124 extending from a larger diameter body portion 126~ The hub 124 receives a square operative shaft 129 of the handle 112, which is rotatable attached to the outside of the door L. The member 122 is rotatable secured in the frame assembly 120 and has a central axis of rotation in common with a central axis of rotation of the member 114. The body portion 126 has a circular outside periphery 127 rotatable received within a circular counter bored recess 128 in the body portion 117. The members 114 and 122 each have a central through-passage 130, 132, respectively, of substantially square cross-section and aligned. The members also each have a cross bore 134, 136, respect-lively, for receiving detents that retain a release mom-bier 140 in the through passages 130, 132.
The release member 140 has a handle portion 142 adjacent the inside operating handle 110 and a square I
rod portion 1~4 extending from the handle portion 142 through the inside handle 110 and, depending upon the position of the release member, into the first rotate able member 114 only (as shown in the phantom position of Figure 3) or into both the first and second rotate able members 114 and 122 (as shown in solid line). The square rod fits closely within the through passages 130, 132 and therefore is not relatively rotatable with respect to the members 114 and 122 when it extends into the through passages. Thus, when in the solid line position, the rod is rotated by the member 114 when the handle 110 is rotated, thereby rotating the second mom-bier 122 and the handle 112. Conversely, rotation of the handle 112 will rotate the member 122, the rod 144, the member 114, which operates the bolts, and the handle 110. When the rod 144 is in the phantom position and not extending into the member 122, rotation of the ken-die 110 will rotate the member 114 but not the member 122 or the handle 122 nor will the locking of the handle 122 in a fixed position prevent rotation of the member by the handle 110.
The rod 144 has a pair of detents 150 positioned to cooperate with the cross bores 134, 136; i.e., post-toned to cooperate with the bores 134 with the end aye withdrawn from the member 122, and with the bores 136 when the end aye extends into the member 122. The detents are ball bearings and are held in a partially extending position from opposite flat surfaces of the rods by a central shaft 154 movable longitudinally with-in the rod and biased by a compression spring 156 to the position shown in Figure 4, where an end 144b ox-tends beyond the handle portion 142. When the end Boyce pressed to move the shaft against the spring bias, a peripheral groove 158 on the shaft is moved into align-mint with the detents, allowing them to retract into aye the rod 144, which can then be moved within the through-passages 130, 132 to one of the two positions shown!
where either both members 114 and 122 rotate together or where rotation of one has no effect on the other.
When the shaft is released and the detents aligned with the cross bores, the shaft will force the detents into the cross bores to retain the rod 144 in the desired position.
From the foregoing, it will be apparent the objects heretofore enumerated and others have been accomplished and that the present invention provides a novel and improved closure mechanism or lock for doors of highway trucks, military vehicles, and the like, including one or more dead bolts which are easily moved into and out of engagement with their keepers under adverse poor closing conditions, and which in one embodiment provides a mechanism for selectively enabling and disabling opera-lion through an outside handle.

The invention resides in the novel constructions and come binations and arrangements of the parts of the lock which accounts for its simplicity of construction and its reliability and ease of operation and further features and advantages will be herein rev-erred to or will become apparent to those skilled in the art to which the invention pertains from the following description of the preferred embodiment depicted in the accompanying drawings.
Figure 1 is a fragmentary, elevation Al view of a closed body highway truck having a lock embodying the present invention - Ed s assembled therewith;
Figure 2 is a fragmentary sectional view approximately on the line 2-2 of Figure 1 looking in the direction of the arrows;
Figure 3 is a fragmentary view partly in section and partly in elevation showing a modified lock embodying the present invention; and Figure 4 is a fragmentary view with parts broken away of the embodiment of Figure 3.
Although the closure control mechanism of the present invention designated generally by the reference character A, can be otherwise employed, it is herein depicted and described as connected to the inside of a - ye pivoted door B of a closed body highway truck, the body of which is designated generally by the reference char-cater C. the door B opens outwardly and is hinged at its left hand vertical side, as viewed in Figure l, to the truck body C. It is to be understood however, that the closure control mechanism A is equally apply-cable to either right or left hand doors. Closure control mechanisms of the type to which the invention no-fates are typically referred to in the trade to which it relates as a "lock' and the closure control motion is depicted in the drawings and herein described will lo be hereinafter sometimes referred to as a lock. The reference character G designates a soft gasket around the door opening in the truck body C against which the door B closes.
The closure control mechanism or lock A comprises top and bottom dead bolt assemblies D, E which are dupe ligates of one another and are connected to the inside of the door adjacent to its free vertical edge 12 and its non-pivoted upper and lower horizontal edges 14, 16 by headed and threaded fasteners indicated by the refer-once character 18. Since the bolt assemblies D, E reduplicates, only the upper assembly D will be herein described in detail and the duplicate parts of assembly E will be designated by the same reference characters with a prime mark affixed thereto.
The bolt assembly D includes a frame or bolt sup-porting bracket 20 comprising a base plate 22 and a channeled top or cover plate 24 equal in size to the plate 22, as viewed in elevation, connected together and to the door B by the fasteners 18. The plates 22, 24 form there between an aperture 26 in which a dead bolt 28 is slid ably supported with at least one end, which in the case of the bolt 28 is the upper end there-of, projecting from the bracket 20 in the direction of I
the adjacent horizontal edge of the door B. This upper end of the bolt 28 which is the end that engages a keeper or catch in the form of a plate 30 connected to the adjacent structure of the door opening of the truck body C, is bifurcated, providing two tines 34, 36 bet-wren which a roller 40 is rotatable supported on a pin 42. The end of the bolt 28 is tapered as at 44 on the side thereof facing in the direction of the door. The roller 40 extends slightly beyond the side of the member in which it is supported facing the inner side of the door and is the part of the bolt which engages the keeper or catch 30, except for the tapered end I of the member 28 there above, as the bolt is moved to a locking post-lion after the door is closed.
The lower end of the bolt 28, that is, the end facing in the direction away from the upper edge 14 of the door B, is also bifurcated, providing front and back tines 50, 52 between which the upper flattened end of a rod 54 for reciprocating the bolt 28 is pivoted on a headed and threaded fastener 56 the shank of which is threaded into a tapped aperture in the tine 52. The lower flattened end of the rod 54 is pivoted to an up-standing or forwardly extending stud or post 60 on a rotatable operating member 62 supported in a frame as-symbol 64 of a bolt operating structure or member design noted generally by the reference character F. The stud 60 is eccentrically located with respect to the axis of rotation of the member 62.
The frame assembly 64 comprises a back plate 66 and a channel-like front or cover member 68 providing an aperture between the members 66, 68 in which the member 62 is rotatable supported by suitable means in-eluding a boss 70 on the rear side (adjacent the door) of the member 62 which is rotatable received in a air-cuter aperture 72 in the plate 66. The stud or pivot pin 60 extends forwardly of the cover plate 68 and is provided with a roller where it projects past the cover plate 68. One side of the lower end of the rod 54 abuts an end of the roller 74 and a cotter pin 76 in the end of the stud 60 engages the other side of the rod to maintain it assembled with the stud 60.
The rotatable member 62 is provided with a driving connection in the form of a square through-aperture 78 concentric with its axis of rotation for the reception and disengagement of a manual tool for oscillating the same to extend and retract the bolt 28. The tool for oscillating the member 62 may include a handle fixed to the member 62, if desired. An aperture H in the door B
in alignment with the aperture 78 allows insertion of a tool such as the tool K for operation of the lock from the exterior of the vehicle. During oscillation of the member 62 the roller 74 rolls along an arcuate surface 80 on the side of the cover plate 68 which surface ton-minutes in reverse bends or arcs 82, I that limit the travel of the roller 74 and in turn the extent of move-mint of the bolt 28.
The rotatable member 62 is resiliently held or biased to whichever of its limited positions to which it is manually moved by a compression spring 90 on the shank of an eye member 92 the eye 94 of which engages about a short stud or projection 96 on the member 62 located at one side of the vertical centerline through the frame assembly 64 and through which centerline the axis of rotation of the member 62 passes. The free end of the shank of the eye member 92 projects through an aperture in lower forwardly extending part 98 of the 30 cover plate 68 the center of which aperture lies in the aforementioned centerline. The lower end of the spring abuts the part 98 of the cover plate 68 and the upper end abuts the member 62.
I
The lower bolt 28' is connected to the rotatable member I in the bolt operating assembly by a rod 54' similar to the rod 54 and connected to the bolt 28' and a second stud or projection 60' on the member 62 in a manner similar to that in which the rod 54 is connected to the bolt 28 and to the stud 60 and the corresponding parts being designated by the same reference characters with a prime mark affixed thereto.
The studs or projections 60, 60' are located 180 from one another about the axis of rotation of the mom-bier 62 from which axis they are offset eccentrically a distance to effect the desired movement of the bolts 28, 28' in their supporting brackets. In operation of the lock, the roller 741 on the stud 60' travels along an arcuate surface Blue similar to the surface 80 and at the ends of its travel abuts reverse arcs 82', 84' in a manner similar to that in which the roller 74 abuts the arcs 82, 84. As the door is closed and the member 62 rotated to secure the door in closed position, the in-dined ends 44, 44' first contact the striker plates 30, 30 1 and upon continuous rotation of the member 62 the rollers 40, 40l engage the plates and draw the door tightly closed compressing the gasket G. The plate-like keepers 30, 30 ' may be omitted if desired and the bolts 28, I allowed to engage directly parts of the truck body adjacent thereto. Alternately, one embody-mint of the invention utilizes tapered plates similarity plates 30, 30 I but that vary in thickness along their length, being relatively thin adjacent the door edge and thicker farther from the edge to form an incline so movement of the bolts into a locking position applies progressively more closing force as the rollers 40, 40' move up the inclines.
As another feature of the invention, the rotatable bolt actuating member 62 is further provided with a cam go type bolt in the form of an arm 110 projecting from one side thereof in the direction away from and normal to the vertical free edge of the door for engagement with a keeper or catch 112 in the form of a plate fixed to the truck body C when the bolts 23, 28' are engaged with their respective keepers or catches 30, 30'. The free end of the arm 11~ carries a roller sleeve 114 for engagement with the keeper 112 to facilitate its enrage-mint and disengagement thereof with the keeper. One end aye of the plate-like keeper 112 is inclined to provide a surface for -the roller sleeve 114 to roll up upon and pull the door closed.
The lock A of the invention is herein shown and described as applied to the inside of an outwardly open-in door B of a closed body highway truck, but it is equally applicable to various closure members even those that are not pivoted along one edge. The depicted lock, for example, can be applied to a door such as the door B but opening inwardly of the truck body by removing the bolts 28, 28' from their supporting brackets 20, 20l, rotating the bolts 180~ about their longitudinal axis and reassembling them with their supporting break-eta. This would necessitate providing either surface mounted or recessed keepers or catches having apertures for the reception of the ends of the bolt or bolts. In the event the center bolt 110 is employed, a suitable 25 keeper or catch would also be provided. Recessed keep-ens or catches are shown in United States Patent No.
3,333,878.
A second embodiment of the invention is shown in Figures 3 and 4 of the drawings, constructed to provide 30 handles 110, 112 on two opposite sides of a door L, the handle 110 being on the inside of a closed compartment of a vehicle and the handle 112 on the outside. This construction is useful on vehicles, such as tactical military vehicles, and allows a person within the vow-ale to selectively disable the outside handle 112 from inside of the vehicle so tile outside handle will not operate the bolts and will not prevent operation of the inside handle. Thus, if the outside handle is padlocked in place the bolts can nevertheless be operated with the inside handle.
A bolt operating assembly M is provided similar to the assembly F, but having a first rotatable member 114 similar to the member 62 but having a hub 116 extending from a larger diameter body portion 117. The member 114 is rotatable received in a frame assembly 120 semi-far to the frame assembly 64. The hub extends from the frame assembly into the vehicle and supports the inside handle 110, which is pinned to the hub. Rotation of the handle rotates the member 114 to actuate the bolts in the same manner as does the member 62.
The bolt assembly M also has a second rotatable member 122 that has a hub 124 extending from a larger diameter body portion 126~ The hub 124 receives a square operative shaft 129 of the handle 112, which is rotatable attached to the outside of the door L. The member 122 is rotatable secured in the frame assembly 120 and has a central axis of rotation in common with a central axis of rotation of the member 114. The body portion 126 has a circular outside periphery 127 rotatable received within a circular counter bored recess 128 in the body portion 117. The members 114 and 122 each have a central through-passage 130, 132, respectively, of substantially square cross-section and aligned. The members also each have a cross bore 134, 136, respect-lively, for receiving detents that retain a release mom-bier 140 in the through passages 130, 132.
The release member 140 has a handle portion 142 adjacent the inside operating handle 110 and a square I
rod portion 1~4 extending from the handle portion 142 through the inside handle 110 and, depending upon the position of the release member, into the first rotate able member 114 only (as shown in the phantom position of Figure 3) or into both the first and second rotate able members 114 and 122 (as shown in solid line). The square rod fits closely within the through passages 130, 132 and therefore is not relatively rotatable with respect to the members 114 and 122 when it extends into the through passages. Thus, when in the solid line position, the rod is rotated by the member 114 when the handle 110 is rotated, thereby rotating the second mom-bier 122 and the handle 112. Conversely, rotation of the handle 112 will rotate the member 122, the rod 144, the member 114, which operates the bolts, and the handle 110. When the rod 144 is in the phantom position and not extending into the member 122, rotation of the ken-die 110 will rotate the member 114 but not the member 122 or the handle 122 nor will the locking of the handle 122 in a fixed position prevent rotation of the member by the handle 110.
The rod 144 has a pair of detents 150 positioned to cooperate with the cross bores 134, 136; i.e., post-toned to cooperate with the bores 134 with the end aye withdrawn from the member 122, and with the bores 136 when the end aye extends into the member 122. The detents are ball bearings and are held in a partially extending position from opposite flat surfaces of the rods by a central shaft 154 movable longitudinally with-in the rod and biased by a compression spring 156 to the position shown in Figure 4, where an end 144b ox-tends beyond the handle portion 142. When the end Boyce pressed to move the shaft against the spring bias, a peripheral groove 158 on the shaft is moved into align-mint with the detents, allowing them to retract into aye the rod 144, which can then be moved within the through-passages 130, 132 to one of the two positions shown!
where either both members 114 and 122 rotate together or where rotation of one has no effect on the other.
When the shaft is released and the detents aligned with the cross bores, the shaft will force the detents into the cross bores to retain the rod 144 in the desired position.
From the foregoing, it will be apparent the objects heretofore enumerated and others have been accomplished and that the present invention provides a novel and improved closure mechanism or lock for doors of highway trucks, military vehicles, and the like, including one or more dead bolts which are easily moved into and out of engagement with their keepers under adverse poor closing conditions, and which in one embodiment provides a mechanism for selectively enabling and disabling opera-lion through an outside handle.
While preferred embodiments have been illustrated and described in detail it is to be understood that the invention may be otherwise embodied and it is the inter lion to cover all adaptations and arrangements thereof which come within the practice of those skilled in the art to which the invention relates and the scope of the appended claims.
