Description
The present invention relates to a device for locking a weapon support, swiveling about a horizontal axis of rotation, of an elevationally trainable weapon, for instance a rapid-fire gun, relative toa member suppor~ing it on the outside of a turret swivelable in a vehicle about a vertical axis of rotation. The device comprises a bore and bolt to the free end of which a handle is attached which is capable of a 180 of rotation, the bolt being axially movable under a spring pressure and moves axially in a helical txack in a casing surrounding the bolt.
The vehicle may be an armored wheel, half-track or full-track vehicle with a full-circle swivelable turret. The locking device makes it possible to selectively secure the weapon in the zero position 'Itied position" of the weapon support or move it in any firing position.
Irrespective of combat, armored wheel, half-track or full-track vehicles are for terrain-related reasons subjected to considerable mechanical stresses. Such stresses require for instance the safe storage of the ammunition for the on-~oard 20 weapons in the vehicle interior. This applies equally to the on-board weapon(s), specifically to a rapid-fire gun on the vehicle. It requires both for off the road and on the road travel a careful and safe securing in its zero or "tied position'.' It were, for instance with impending weapon use, the on-board weapon must in the shortest possible time be in firing readiness.
This requires that the fixing of the weapon in the zero or "tied position" can be eliminated as quic~ly as possible.
The aforementioned locking device has the disadvantage that due to its ~ounting onthe outside of the vchicle and/or vchicle turret the device can only from the outside be rendered o~erational or non-operational. For this purpose it is neccssary that a crew member get outside tlle armor protection ~;i6~JS~
provided by the vehicle and the turret. The resulted hazard for the soldier operating ~he locking device is to be viewed, as a considerable disadvantage.
The invention provides a locking device of the above type which allows the crew member operating the device to re-main within the armor portection and which, moreover, effects the locking in a particularly simple, quick and trouble-free manner, without requiring visual observation of the exactly corresponding position of the bore and bolt pairing of the device.
According to the present invention there is provided an apparatus for securing and releasing a weapon support of an armored vehicle from inside the turret of the vehicle, comprising a casing fixed in the turret and forming a guideway communicating with the exterior and interior of the turret, a bolt axially received in the guideway having one end exterior to the turret, a handle connected to the other end of the bolt interior to the turret for rotating the bolt about 180 degrees within the guideway, a bore in the weapon support for receiving the one end of the bolt, a spring axially biasing the one end of the bolt into engagement with the bore, an index pin connected to the bolt and extending transverse to the axis of the bolt, a gate in the casing for receiving the index pin, the gate including a helical track and a guide surface opposite the track for engaging the index pin in response to axial movement of the bolt, the index pin communicating with the track and being movable between latching, unlatching, and intermediate latching positions when the bolt is rotated in the casing, and run-on surfaces on the weapon support adjacent to the bore, the one end of the bolt engaging the run-on surfaces when the index pin is in the intermediate latching position whereby swivel movement of the weapon support causes the run-~ 2 -5~
on surfaces to axially move the bolt against the force o~ the spring and the guide surface to guide the pin into the latching position.
- Thus, according to the present invention the bore is lQ
, , . . .
. . -2a ~
arranged in the weapon support while the bol~ housing i5 located in the turret hood and extends into its interior. Further, the helical track i9 contained in a gate which between the limit engagemen~ positions for locking and unlocking, has an intermediate engagement position for the bolt for moving it during the weapon support swivel, onts faces which flank the bore in the weapon support in the engagement area of the bolt, with the axial movement generared upon run-on of the bolt exceeding the spring pressure and allowing forced control of an index pin firmly connected with the bolt, into the locking position by the gate.
Since the bolt casing is located in the turret hood and extends into its interior, with the gate also disposed inside the turret hood, the soldier operating the locking device is no longer endangered in the sense explained above, irrespect-ive of whether a locking or unlocking action is intended. For unlocking, the device needs to be moved, according to the invention, only into the intermediate locking position for the bolt. As soon as the weapon is lowered or raised and the bolt encounters during the weapon support swivel one or the other run-on face, an axial bolt movement is of necessity generated which is transmitted also to the index pin firmly connected with it. The index pin is force-controlled into the locking position by the gate. Obtained without further assistance of the person responsible for the locking device is thus a very simple, quick and trouble-free locking in blind action. An arm is desirably rigidly connected with the bolt is which in the locking position runs on a signal head fastened on the turret, tllereby signaling its proper arrival in the locking position.
Further, the bore and bolt desirably have a slightly conical shape in order to additionally facilitate the automatic latching in that the end surface of the bolt has a smaller diame-ter than the entrance of the bore opposite the end surface of the bolt. When mated, this provides the further advantage of a latching without play, which is still effective with wear.
The gate desirably has an inclined, force control surface which is located axially opposite the intermediate latching position and swivels the index pin during its axial movement in a direction toward the latching position. As soon as the bolt, under spring pressure, can engage the bore, it moves axially again in an opposite direction whereby the index pin moves into the limit latching position for locking. These movements take place completely automatically.
The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a side elevation, partially broken away of a turret of an armored vehicle(not shown in detail)with a weapon support and rapid-fire gun;
Figure 2 is a rear view of the turret,of Fig. 1 from the rear in the direction of travel;

Referring to the drawings a turret 1 is mounted on a wheel, half-track or full-track vehicle (not shown) in a conventional manner so as to swivel about a vertical axis of rotation 5. Rigidly connected with the turret 1, on its outside, is a weapon standard 2 on which a weapon support 3 is mounted in a manner allowing elevational training about a horizontal axis of rotation 2a. Arranged on the weapon support 3 is an on-board weapon~ for instance a rapid-firP gun 4. In order to home in on a target, the sideways training of the weapon 4 thus takes place by swiveling the turret 1 around its vertical axis of rotation ~. Elevational training of the weapon 4 is accomplished by swîveling the weapon support 3 on the weapon standard 2 about a horizontal axis 2a. A hatch la disposed of in the direction of travel on the far side of the weapon standard
The vehicle may be an armored wheel, half-track or full-track vehicle with a full-circle swivelable turret. The locking device makes it possible to selectively secure the weapon in the zero position 'Itied position" of the weapon support or move it in any firing position.
Irrespective of combat, armored wheel, half-track or full-track vehicles are for terrain-related reasons subjected to considerable mechanical stresses.

It were, for instance with impending weapon use, the on-board weapon must in the shortest possible time be in firing readiness.
This requires that the fixing of the weapon in the zero or "tied position" can be eliminated as quic~ly as possible.
The aforementioned locking device has the disadvantage that due to its ~ounting onthe outside of the vchicle and/or vchicle turret the device can only from the outside be rendered o~erational or non-operational. For this purpose it is neccssary that a crew member get outside tlle armor protection ~;i6~JS~

Further, the helical track i9 contained in a gate which between the limit engagemen~ positions for locking and unlocking, has an intermediate engagement position for the bolt for moving it during the weapon support swivel, onts faces which flank the bore in the weapon support in the engagement area of the bolt, with the axial movement generared upon run-on of the bolt exceeding the spring pressure and allowing forced control of an index pin firmly connected with the bolt, into the locking position by the gate.
Since the bolt casing is located in the turret hood and extends into its interior, with the gate also disposed inside the turret hood, the soldier operating the locking device is no longer endangered in the sense explained above, irrespect-ive of whether a locking or unlocking action is intended. For unlocking, the device needs to be moved, according to the invention, only into the intermediate locking position for the bolt. As soon as the weapon is lowered or raised and the bolt encounters during the weapon support swivel one or the other run-on face, an axial bolt movement is of necessity generated which is transmitted also to the index pin firmly connected with it.

When mated, this provides the further advantage of a latching without play, which is still effective with wear.
The gate desirably has an inclined, force control surface which is located axially opposite the intermediate latching position and swivels the index pin during its axial movement in a direction toward the latching position.

These movements take place completely automatically.
The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a side elevation, partially broken away of a turret of an armored vehicle(not shown in detail)with a weapon support and rapid-fire gun;
Figure 2 is a rear view of the turret,of Fig. 1 from the rear in the direction of travel;
Figure 3 is a vertical section through -the latching device of Fig. 1 serving to fix or release the weapon support;
Figure 4 is a schematic of the switching positions of the turnable handle of the device of Figure 3, and;
Figure 5 is a gate type guide as a forced control with defined latching positions.
Referring to the drawings a turret 1 is mounted on a wheel, half-track or full-track vehicle (not shown) in a conventional manner so as to swivel about a vertical axis of rotation 5. Rigidly connected with the turret 1, on its outside, is a weapon standard 2 on which a weapon support 3 is mounted in a manner allowing elevational training about a horizontal axis of rotation 2a. Arranged on the weapon support 3 is an on-board weapon~ for instance a rapid-firP gun 4. In order to home in on a target, the sideways training of the weapon 4 thus takes place by swiveling the turret 1 around its vertical axis of rotation ~. Elevational training of the weapon 4 is accomplished by swîveling the weapon support 3 on the weapon standard 2 about a horizontal axis 2a. A hatch la disposed of in the direction of travel on the far side of the weapon standard
2 can be closed by means of a hatch cover lb. The opening radius of the cover lb is indicated by arrow lc (Figure 2).
The device for latching the weapon support 3 relative to the weapon standard 2 and/or the turret 1 comprises a bore lOb and a bolt 8 to the f-ree end of which there is attached a turning handle 6 rotatable through 180~. Thé ~olt ~ is axially movable under the bias of the spring and extends length-wise in a helical track contained in a housing 7 surrounding the bolt 8.
The bore lOb is disposed in the weapon support 3. The ~ bolt housing 7 is in the hood of the turret 1 and extends into - its interior. The helical track is contained also in a gate 7a tsee Figures 3 and 5) which has between the limit latching positions 7b, Eor locking, and 7d, for unlocking, an intermediate latching position 7c for the bolt 8 to run onto run-on surfaces lOa as the weapon support 3 swivels, which run-on surfaces lOa flank the bore lOb in the weapon support 3 in the engagement area of the bolt 8. With the illustrated, preferred embodiment the run-on surfaces lOa are provided on a locking bar 10 which is fastened on the weapon support 3. The axial movement generated by the run-on of the bolt 8 overcomes the pressure spring 9 and causes an index pin 11 which is rigidly connected t]~ereto to be force-controlled by the gate 7a into the latching position 7b.
The index pin 11 is transverse to the bolt 8 and runs in the manner to be seen from Figures 3 and 5 in the gate 7a of the bolt casing 7. Illustratea for example in Fi~ure 4, is the turning handle 6 and in Figure 5,for example, the index pin 11, each in its three defined latching positions, with the corresponding positions 6 and 7b serving the locking and/or tying, the positions 6a and 7c the partial. unlatching and/or untying (so-called inte~mediate latching position) and, lastly, the positions 6b and 7d the unlatching and/or untying of the bolt 8, which on its upper end 8a is slightly conical, relative to the recess lOb which is appropriately shaped and arranged in the locking bar 10.
In the illustrated, preferred embodiment the gate 7a has an inclined force-control face 7e which is axially located opposite the intermediate latching position 7c. When it is desired to move the device into a latching position.in which the index pin 11 is in position 7b, the soldier operatiny the latching device only neéds to move the turning handle 6 froM the position 6b (Figure 4), which corresponds to the unlatching position 7d of the index pin 11, to the position 6a, which corresponds to the partial unlatching position 7c o:E the index pin 11. In this context, it is pointed out that the top edge of gate 7a, in Figure 5, is relative to Figure 3 turned upside down, whereas the bottom edge of the gate is turned up. ~hen row swiveling the weapon support 3 for latching purposes around the horizontal axis of rotation 2a in order to cause the bore lOb and the cone 8a of the bolt 8 to engage, either one or the other run-on faces lOa of the locki.ng bar 10, dcpending on whether the weapon support 3 is turned up or down, runs onto the conical portion 8a which in the intermediate latchi.ng position 7c extends a certain length above the surface of the turret 1.
Created thereby is of necessity an axial downward movement of the bolt 8 in Figure 3 against the force of tl-e helical compression spring 9, which force is transmitted to the index pin 11. As a result, the index pin 11 strikes the force-control face 7d and is turned as the bolt 8 continues its axial movement in the direction towardsthe latching position 7b, shown in Figure 5, that is, to the right. As soon as the bolt 8 and/or its cone 8a engages the bore lOb and is thus permitted to move under the effect of the helical compression spring 9 axially inthe opposite direction, the index pin 11 moves also in the appropriate direction and latches positively, according to Figure 5, in the position illustrated by solid lines. Both the bolt 8 and the index pin 11 are held in this latching position 7b by the effect of the helical compression sprlng 9.
The device of the present invention thus assures a very simple, quick and trouble-free latching, so to speak, in blind operation, without requiring the soldier operating the latching device to do more than move the turning handle 6 from the position 6b, which corresponds with the unlatching position 7d of the index pin 11, into position 6a, which corresponds with the intermediate latching position 7c of the index pin 11.
Rigidly connected with the bolt 8 is an arm 12 which in ~0 the latching position 7b runs on a turret-mounted signal button 13 and signals the complete latchingby means of an acoustic and/
or optical signal 13', 14 which indicates to the commander or the gunner, that ~he weapon support 3 with the rapid-fire gun 4 is latched and/or tied. In the opposi~e case, when the acoustic signal ceases or the optical indication turns off, the crew is able to recogni~e that the mechanical locking between turret 1 and weapon support 3 has been eliminated and/or is in the partial unlatching position. When the rapid-fire gun 4 is to be readicd for firing from the latching position 7b, the turning handle 6 is moved to the position 6b in which the index pin 11 is located again in the unlatching position 7d. The cone 8a of bolt 8 disengages, through the resulting axial shift, the bore lOb of ~6~
the locking bar 10. The necessary downward, axial movement against the force of the helical spring 9 surrounding the shaf~
of the bolt 8, in Figure 3/ is controlled by the index pin 11 which runs in the gate 7a and moves into the ~nlatching position 7d.
For the sake of completeness it is pointed out that Figure 5, naturally, represents a roll-off of the gate 7a, which according to Figure 3 extends down the wall of the bolt casing 7 and, thus, in its peripheral direction. Also, it is pointed out that it would be possible, ~s the case may be, to make do without a separate turning handle 6 and, instead, make the index pin 11 sufficiently long to serve as an operating handle.
The device for latching the weapon support 3 relative to the weapon standard 2 and/or the turret 1 comprises a bore lOb and a bolt 8 to the f-ree end of which there is attached a turning handle 6 rotatable through 180~. Thé ~olt ~ is axially movable under the bias of the spring and extends length-wise in a helical track contained in a housing 7 surrounding the bolt 8.
The bore lOb is disposed in the weapon support 3. The ~ bolt housing 7 is in the hood of the turret 1 and extends into - its interior. The helical track is contained also in a gate 7a tsee Figures 3 and 5) which has between the limit latching positions 7b, Eor locking, and 7d, for unlocking, an intermediate latching position 7c for the bolt 8 to run onto run-on surfaces lOa as the weapon support 3 swivels, which run-on surfaces lOa flank the bore lOb in the weapon support 3 in the engagement area of the bolt 8. With the illustrated, preferred embodiment the run-on surfaces lOa are provided on a locking bar 10 which is fastened on the weapon support 3. The axial movement generated by the run-on of the bolt 8 overcomes the pressure spring 9 and causes an index pin 11 which is rigidly connected t]~ereto to be force-controlled by the gate 7a into the latching position 7b.
The index pin 11 is transverse to the bolt 8 and runs in the manner to be seen from Figures 3 and 5 in the gate 7a of the bolt casing 7. Illustratea for example in Fi~ure 4, is the turning handle 6 and in Figure 5,for example, the index pin 11, each in its three defined latching positions, with the corresponding positions 6 and 7b serving the locking and/or tying, the positions 6a and 7c the partial. unlatching and/or untying (so-called inte~mediate latching position) and, lastly, the positions 6b and 7d the unlatching and/or untying of the bolt 8, which on its upper end 8a is slightly conical, relative to the recess lOb which is appropriately shaped and arranged in the locking bar 10.
In the illustrated, preferred embodiment the gate 7a has an inclined force-control face 7e which is axially located opposite the intermediate latching position 7c. When it is desired to move the device into a latching position.in which the index pin 11 is in position 7b, the soldier operatiny the latching device only neéds to move the turning handle 6 froM the position 6b (Figure 4), which corresponds to the unlatching position 7d of the index pin 11, to the position 6a, which corresponds to the partial unlatching position 7c o:E the index pin 11. In this context, it is pointed out that the top edge of gate 7a, in Figure 5, is relative to Figure 3 turned upside down, whereas the bottom edge of the gate is turned up. ~hen row swiveling the weapon support 3 for latching purposes around the horizontal axis of rotation 2a in order to cause the bore lOb and the cone 8a of the bolt 8 to engage, either one or the other run-on faces lOa of the locki.ng bar 10, dcpending on whether the weapon support 3 is turned up or down, runs onto the conical portion 8a which in the intermediate latchi.ng position 7c extends a certain length above the surface of the turret 1.
Created thereby is of necessity an axial downward movement of the bolt 8 in Figure 3 against the force of tl-e helical compression spring 9, which force is transmitted to the index pin 11. As a result, the index pin 11 strikes the force-control face 7d and is turned as the bolt 8 continues its axial movement in the direction towardsthe latching position 7b, shown in Figure 5, that is, to the right. As soon as the bolt 8 and/or its cone 8a engages the bore lOb and is thus permitted to move under the effect of the helical compression spring 9 axially inthe opposite direction, the index pin 11 moves also in the appropriate direction and latches positively, according to Figure 5, in the position illustrated by solid lines. Both the bolt 8 and the index pin 11 are held in this latching position 7b by the effect of the helical compression sprlng 9.
The device of the present invention thus assures a very simple, quick and trouble-free latching, so to speak, in blind operation, without requiring the soldier operating the latching device to do more than move the turning handle 6 from the position 6b, which corresponds with the unlatching position 7d of the index pin 11, into position 6a, which corresponds with the intermediate latching position 7c of the index pin 11.
Rigidly connected with the bolt 8 is an arm 12 which in ~0 the latching position 7b runs on a turret-mounted signal button 13 and signals the complete latchingby means of an acoustic and/
or optical signal 13', 14 which indicates to the commander or the gunner, that ~he weapon support 3 with the rapid-fire gun 4 is latched and/or tied. In the opposi~e case, when the acoustic signal ceases or the optical indication turns off, the crew is able to recogni~e that the mechanical locking between turret 1 and weapon support 3 has been eliminated and/or is in the partial unlatching position. When the rapid-fire gun 4 is to be readicd for firing from the latching position 7b, the turning handle 6 is moved to the position 6b in which the index pin 11 is located again in the unlatching position 7d. The cone 8a of bolt 8 disengages, through the resulting axial shift, the bore lOb of ~6~
the locking bar 10. The necessary downward, axial movement against the force of the helical spring 9 surrounding the shaf~
of the bolt 8, in Figure 3/ is controlled by the index pin 11 which runs in the gate 7a and moves into the ~nlatching position 7d.
For the sake of completeness it is pointed out that Figure 5, naturally, represents a roll-off of the gate 7a, which according to Figure 3 extends down the wall of the bolt casing 7 and, thus, in its peripheral direction. Also, it is pointed out that it would be possible, ~s the case may be, to make do without a separate turning handle 6 and, instead, make the index pin 11 sufficiently long to serve as an operating handle.
