[0001] Title: Hand-deployable active body with a manually grippable housing body and method for operating an active body
[0002] Description
[0003] The invention relates to a hand-thrown active device, with a manually grippable housing body, with a manually operable triggering device with a spring-loaded striking body, with an ignition device which can be initiated by the triggering device and which comprises an ignition charge, with a delay device which can be initiated by the ignition device and which comprises a delay charge and a delay section, and with an active device which can be initiated directly or indirectly by the delay charge. The invention therefore relates to an active device which is manually triggered or ignited and is then manually thrown away by the user. In particular, it can be a hand grenade or a decoy. Accordingly, the active device comprises an explosive device or another pyrotechnic active device.It should be noted that the term "initiate" is chosen and used throughout the present application to refer to any type of ignition, igniting or triggering of a combustion or transfer of a pyrotechnic composition or explosive device of whatever type.
[0004] Active elements of the type mentioned above usually have so-called rocker arm trigger devices, which have so far been used for cylindrical designs. These systems usually comprise a safety pin with a ring that can be gripped and pulled by the user's finger, as well as a safety bracket and a pre-tensioned firing spring, whereby the safety bracket holds the firing spring in its pre-tensioned state when in a position secured by the safety pin. When the safety pin is pulled out, the safety bracket can pivot away under the action of the pre-tensioned firing spring and the firing spring can then act as an impact element or by means of an impact element to initiate the ignition device or its ignition charge. The subsequent delay device with its delay charge gives the user sufficient time to throw away the active element.US 2012 / 0288830 A1 shows an active element which, however, does not comprise a pyrotechnic delay charge, but rather has a mechanically implemented delay device which delays the pivoting of a rocker arm. In a previously known non-lethal hand grenade of the ABC-M25A2 type, a firing pin comprising an ignition charge is under permanent spring force even before intended use and is secured by a safety pin with a pull ring. US 1,897,992 describes a rod-like active element for the expulsion of irritant or irritant gases, in which a manually tensionable and triggerable striking mechanism for igniting the gas discharge is provided in a handle section.
[0005] Other trigger devices known to date generally utilize pre-tensioned firing springs, which is inherently complex and potentially risky. Furthermore, once the safety pin has been removed, it is no longer possible to re-secure the trigger device. Grasping and removing the safety pin generally also prevents one-handed operation. Furthermore, the trigger device represents an additional component to the ignition device and delay device.
[0006] The object of the present invention is to create a more compact design. In further development of the invention, further disadvantages of the above-described should also be avoided. This object is achieved according to the invention in a hand-deployable active body of the type mentioned at the outset in that the spring-preloaded impact body comprises the ignition device including the ignition charge and the delay device including the delay charge and including the delay section, and that the impact body can be brought manually along its longitudinal axis against a spring force into a preloaded position and releasably locked there and can be released by manually operating a trigger element of the trigger device, so that it can spring from its preloaded position along the longitudinal axis against an axial stop and in this way initiate the ignition charge.
[0007] According to the invention it is therefore proposed that the use of a safety split pin with a ring and safety bracket as well as a pre-tensioned firing spring be dispensed with and that instead the triggering device is designed in such a way that the striking body can only be manually moved into a pre-tensioned position and releasably locked there when this is necessary. Also no separate striking body is provided, but the striking body simultaneously accommodates and encloses the ignition device and the delay device. Thus, unlike in the prior art, a separate striking body is not accelerated against an ignition device, usually in the form of a so-called primer cap, but the ignition device and the delay device form the striking body in a sense and are thrown against an axial stop, which can also be referred to as an anvil, so that the ignition charge is initiated.In a further development of the invention, it proves advantageous if the impact body is at least partially sleeve-shaped and forms a receiving space for the ignition device and the delay device. In this way, the ignition charge and the delay charge can be connected to one another to a certain extent and accommodated in the receiving space formed by the sleeve-shaped impact body.
[0008] The impact body, which is movable along its longitudinal axis, can be accommodated in any desired manner within the housing body so that it can be moved longitudinally. However, in a further development of this concept, it proves advantageous if the impact body is guided longitudinally along its longitudinal axis within a helical spring, with the helical spring being axially supported at one end, directly or indirectly, against the housing body with respect to the longitudinal axis.
[0009] Furthermore, it proves advantageous if the helical spring is connected to the impact body at its other end or is supported against the impact body in the direction of the longitudinal axis, in particular against a radial projection of the impact body. In this way, a space-saving arrangement of the spring and the impact body within the housing body can be realized in the longitudinal direction. The aforementioned radial projection of the impact body can be formed, for example, by an external step, an annular collar or a pin-shaped projection or the like.
[0010] In a preferred embodiment of the active body according to the invention, it is provided that the triggering device comprises a manually grippable tensioning element, by means of which the impact body can be brought into its pre-tensioned position.
[0011] This clamping element can be formed by the impact body itself, in particular by its outer surface or by a laterally projecting portion of the impact body. However, it can also be a separate, manually grippable clamping element that is drive-connected to the impact body in the direction of its longitudinal axis.
[0012] According to a further preferred embodiment, it is proposed that the manually grippable clamping element be arranged so as to be pivotable about its longitudinal axis relative to the housing body and, in particular, also relative to the impact body. The pivotable arrangement of the clamping element makes it possible to provide additional functionalities or to move the clamping element from an actuatable position to a non-actuatable position in a single adjustment process, for example, using the user's thumb.
[0013] Furthermore, it has proven advantageous if the manually gripped clamping element can be moved back and forth between a safety position and a clamping position, and if the impact body is held at a distance from the axial stop in the direction of the longitudinal axis when the manually gripped clamping element is in the safety position, and if the impact body can be moved back and forth in the direction of the longitudinal axis when the manually gripped clamping element is in the clamping position. When the clamping element is in the safety position, this also ensures that the impact body cannot inadvertently strike the axial stop and thereby initiate the ignition device. The clamping element therefore performs a clamping function on the one hand and a safety function on the other.
[0014] Following the tensioning process, it is advantageously provided that the impact body can be releasably locked in its pre-tensioned position by a spring-loaded locking element positively engaging behind the impact body in the direction of the longitudinal axis. This allows the impact body to be held in its pre-tensioned state. The positive engagement behind the impact body in the longitudinal direction means that any locking element engages in a engageable area on the impact body transversely to the longitudinal direction.
[0015] In a further development of this idea, it is proposed that the spring-loaded locking member is linearly displaceable back and forth transversely to the longitudinal axis and has a through opening extending in the direction of the longitudinal axis, through which the impact body can be moved when the locking member is in a position in which the through opening of the locking member is aligned with the longitudinal axis of the impact body.
[0016] This design allows the locking element to be guided and supported on both sides of the impact body, which makes it easier to absorb the resulting forces and dissipate them evenly into the housing body, so that jamming of the components can be better prevented.
[0017] It is also advantageous if the spring-loaded locking member is designed in the shape of a piston, rod or shaft section and is accommodated in the housing body so as to be displaceable transversely to the longitudinal axis.
[0018] It may also prove advantageous if the spring-loaded locking member has an outer circumferential constriction which forms an insertion bevel for the impact body in the direction of the through opening.
[0019] It is particularly advantageous if the manually operated trigger element of the triggering device also forms the spring-loaded locking element. This additional measure also allows for a compact design by reducing the number of parts.
[0020] The trigger element of the triggering device should be positioned near the housing body so that it is easily accessible. It is advantageous if the spring-loaded locking element projects outward beyond the housing body with one free end when it is in its position for locking the impact body.
[0021] According to a further idea of essential importance, it is proposed to design the active body in such a way that its housing body is essentially cuboid-shaped and flat and comprises a first direction and a second direction and a third direction which are orthogonal to one another and extend along or parallel to respective edges of the housing body, wherein the first direction runs along the longitudinal axis of the impact body, and wherein the dimension of the housing body in the first direction is greater than in the second and third directions and preferably the dimension of the housing body in the second direction is greater than in the third direction, and that the housing body delimits a first and a second receiving space,which both extend along the first direction and are arranged next to one another in the second direction, and in that the manually operable triggering device with ignition device and delay device is accommodated in the first receiving space, and in that the active charge is accommodated in the second receiving space. The design of the housing body as a preferably flat, cuboid-shaped housing body proves to be advantageous because the active body can then be held haptically well in the hand of a user and can be actuated. Furthermore, it proves to be advantageous if the first and the second receiving space are preferably separated from one another by a wall extending along the first direction, wherein the wall is thin or has openings so that a transfer of ignition from the delay charge to the active charge is possible through the wall.
[0022] With this cuboidal design of the housing body, it proves to be advantageous if the manually grippable clamping element projects outwards beyond the housing body in its securing position in the second direction.
[0023] In such a case, it is conceivable to arrange the clamping element in such a way that the user can operate it with his thumb and move it from the locking position to the clamping position and vice versa.
[0024] It proves to be advantageous if the manually grippable tensioning element can be pivoted from its securing position into its tensioning position and, in the tensioning position, projects outwards beyond the housing body in the third direction. In particular, it is possible and therefore proves to be advantageous for the tensioning element and the triggering element of the triggering device to be arranged on the housing body in such a way that the active body can be operated with one hand, in particular for pre-tensioning the impact body and for triggering the triggering device. Furthermore, it proves to be advantageous if the above-mentioned spring-biased locking member projects outwards beyond the housing body in the second direction when it is in its position blocking the impact body. In particular, it can be arranged in such a way that the user can press the locking member back into the housing body by applying finger pressure.
[0025] According to a further inventive idea of independent significance, protection is claimed for a method having the features of claim 20 .
[0026] The method according to the invention proves to be advantageous because it allows the active body to be operated with one hand.
[0027] For this purpose, it is further advantageous if the tensioning element is moved from its locking position into its tensioning position, in particular pivoted, in particular and preferably by means of the thumb of a user's hand holding the impact body. The user can then use the same or another finger of the same hand to actuate the triggering device, so that the tensioned impact body springs against a stop and the ignition is initiated.
[0028] In a further development of the method, it is proposed that, in order to releasably lock the impact body in its pre-tensioned position, a spring-loaded locking member is automatically brought into a position which locks the impact body along the longitudinal axis when the impact body is tensioned.
[0029] It is also advantageous if the locking element protrudes from the housing body in the position blocking the impact body and is pressed back into the housing body as a trigger element in order to release the impact body.
[0030] It is also advantageous if the impact body, including the spring means, is accommodated in a guide housing body that can be inserted into the housing body and can be inserted into the housing body together with the guide housing body. In this way, a prefabricated unit comprising the components of the manually operable triggering device with impact body, triggering device, ignition device, and delay device can be provided and inserted into the housing body.
[0031] The subject matter of the method according to the invention also includes all measures with procedural content which were previously explained in connection with the structural design of the active body.

[0044] The figures show various views of an active device according to the invention which can be thrown by hand and is designated overall by the reference numeral 2. The active device 2 comprises, by way of example and preferably, a flat, particularly cuboid-shaped housing body 4. The active device 2 further comprises a manually operable triggering device 6 which is accommodated in a first receiving space 8 of the housing body 4. In an adjacent second receiving space 10 there is accommodated an active charge 12 (not shown in detail), which can ultimately be initiated with a delay in a manner to be explained below and which is, for example, an explosive device or another pyrotechnic active device, as is used in particular in decoys.
[0045] The triggering device 6 includes a spring-loaded impact body 14, which, in the exemplary and preferred case shown, is preloaded by a helical spring 16 and, at the same time, is guided for longitudinal displacement in the first receiving space 8. The helical spring 16 is supported at one end, directly or indirectly, against the housing body 4 and at the other end against the impact body 14, so that the impact body 14 is linearly movable and preloaded along a longitudinal direction or longitudinal axis 18.
[0046] According to the invention, the impact body 14 is not merely formed by a mass body by means of which a kinetic impulse can be exerted on an ignition device of the active body, but the impact body 14, in the exemplary and preferred case shown, is partially sleeve-shaped and simultaneously accommodates in its interior an ignition device 20 including ignition charge 22 and a delay device 24 including delay charge 26. The ignition device 20 and delay device 24 are therefore part of the impact body 14 and are tensioned and triggered together with it in a manner to be described below.
[0047] The triggering device 6 further comprises a manually grippable tensioning element 28 which, in the exemplary and preferred case shown, is pivotally connected to the impact body 14. The tensioning element 28 forms a type of pivoting lever and can be pivoted between a securing position 30 shown in Figure 1 and a tensioning position 32 shown in Figures 2 and 4. The tensioning element 28 is initially drive-connected to the impact body 14 with respect to the longitudinal axis 18. For example, it is provided axially between two radial projections or annular flanges or is drive-connected to the impact body 14 in some other way. In order to explain this even better, a first direction 34, a second direction 36 and a third direction 38 of the housing body 4, which run orthogonally to one another and are shown in the figures. The first direction 34 runs parallel to the longitudinal axis 18.Accordingly, the respective edges of the housing body 4 extend along one of the three directions, provided that the housing is ideally cuboid-shaped, although this does not necessarily have to be the case. The preferred housing body 4 shown as an example is, however, to be regarded as flat and cuboid-shaped insofar as its dimensions in the first direction 34 are greater than in the second direction 36 and greater than in the third direction 38. In the case shown as an example, the clamping element 28 extends outwards in the second direction 36 over the housing body 4 in its secured position 30 so that it can be easily touched and actuated, for example with the thumb of a user. In this secured position 30, the clamping element 28 extends outwards through a slot 40 in a housing wall 42 (best seen in Figure 2).It is therefore held in a form-fitting manner with respect to the longitudinal direction 18 by flanks of the wall 42 of the housing body 4 which border the slot 40. As a result, the impact body 14 is also held or fixed with respect to the longitudinal axis 18. It can be seen that in the secured position of the clamping element 28, a free longitudinal end 44 of the impact body 14 is spaced at a distance in the direction of the longitudinal axis 18 from an axial stop 46 (not yet mentioned), which can also be referred to as an anvil, within the first receiving space 8. If the clamping element 28, starting from the secured position 30 shown in Figure 1, is pivoted about the longitudinal axis 18 by 90° here as an example, so that it projects beyond the housing body 4 in the third direction 38 (as can be seen from Figure 4), then it is in its clamped position 32.In this clamping position 32, the clamping element 28 and, with it, the impact body 14 can be moved against the spring tension and along the longitudinal axis 18 into the pre-tensioned position 48 of the impact body 14 shown in Figure 2. This can also be accomplished by means of the thumb of a user's hand holding the cuboid-shaped housing body 4.
[0048] As soon as the tensioning element 28 and with it the impact body 14 are brought into the pre-tensioned position 48 shown in Figure 2, the impact body 14 is automatically releasably locked in its pre-tensioned position 48. This is achieved in that the triggering device 6 further comprises a spring-tensioned locking member 50 which can be moved back and forth transversely to the longitudinal axis 18, specifically along an axis 52 extending orthogonally to the longitudinal axis 18. The locking member 50 is pre-tensioned in the direction of the axis 52 by means of a spring element 54. It comprises a through opening 56 which extends along the longitudinal axis 18, so that, as shown in Figure 1, the impact body 14 can extend through this through opening 56.If the impact body 14 is now brought from the position shown in Figure 1 into its pre-tensioned position 48 shown in Figure 2 by means of the tensioning element 28, the locking member 50 snaps from its position shown in Figure 1 into the position shown in Figure 2. The locking member 50 then moves in front of the free longitudinal end 44 of the impact body and supports or secures the impact body 14 in the pre-tensioned position 48 shown in Figure 2. As can also be seen from Figure 2, the locking member 50 extends outwards through an opening 57 in the wall 42 of the housing body 4 and projects outwards beyond the housing body 4 in the second direction 36. An outwardly projecting region or free end 58 of the locking member 50 simultaneously forms a triggering element 60 of the triggering device 6, as can easily be seen from the figures.If, starting from the pre-tensioned position 48 of the impact body 4 shown in Figure 2, a user actuates the trigger element 60 by exerting finger pressure on the free end 58 of the locking member 50, the locking member 50 is moved along the axis 52 back into the position shown in Figure 1. When this position is reached, the impact body 14 is aligned with the clear cross-sectional area of the through opening 56 of the locking member 50 and is then suddenly accelerated along the longitudinal axis 18 by the relaxation of the helical spring 16. It snaps against the axial stop 46. The resulting impulse transfer causes an impact ignition, and the ignition device 20 provided inside the impact body 14 immediately adjacent to the free longitudinal end 44 of the latter is initiated. Based on this, the delay device 24 and its delay set 26 are initiated.The user must now quickly throw the active body towards its destination, where the active charge 12 is then ignited starting from the burning delay charge.
[0049] To ensure this, it can be provided that, starting from the end of the delay section, i.e. from the end of the burning delay charge 26, a direct ignition to the active charge 12 takes place, thus initiating the active charge 12. For this purpose, an opening 63 is formed, by way of example, in a separating web 61 inside the housing body 4 in Figures 1 and 2, which separates the active charge 12 from the triggering device 6 and the delay device 24. However, a plurality of openings 63 can also be formed in the separating web 61. Furthermore, it is alternatively or additionally conceivable that a pyrotechnic ignition means, for example in the form of a fuse, is provided between the delay device 24 with its delay charge 26 and the active charge 12, which connects to the end of the delay section and then leads to the active charge 12.It is also conceivable, and is indicated by way of example in Figures 1 and 2, that a detonator 68 with a primary charge and a secondary charge is provided in a sleeve-shaped receptacle 70 between the delay device 24 with its delay charge 26 and the active charge 12. This detonator is connected to the end of the delay section and the initiation of which then leads to the initiation of the active charge 12. The sleeve-shaped receptacle 70 of the detonator 68 is pushed onto the likewise sleeve-shaped receptacle of the delay device 24 and together with it forms the impact body 14.
[0050] Figure 7 shows a longitudinal sectional view of the delay device 24 with the ignition device 20 and the ignition charge 22, which can be designed in the form of a known percussion cap. The longitudinal extension of the delay charge 26 forms the delay section. Figure 8 shows a longitudinal sectional view of the detonator 68 with the primary charge 72 and the secondary charge 74.
[0051] The impact body 14, including the ignition charge 22, the delay charge 26, and the downstream detonator 68, are accommodated in a prefabricated guide housing body 76, which can be inserted into the housing body 4, with the coil spring 16 interposed, and is longitudinally displaceable. This guide housing body 76 is shown in various views in Figures 9a-e, but is not shown in Figures 1 and 2. The guide housing body 76 comprises an elongated opening 78 in the longitudinal direction, which has a step 80 (not shown), against which the coil spring 16 can be axially supported. Furthermore, on the side facing the separating web 61, a transverse opening 82 is formed, which is aligned with the opening 63 in the separating web 61, so that a transfer of ignition and thus initiation of the active charge 12 can occur through these openings 82, 63. The transverse openings 84 shown above serve for the passage of the blocking element 50.At the lower end of the guide housing body 76, the longitudinal opening 78 opens and is aligned there with an opening 86 in the housing body 4, which is visible in Figures 1 and 2 and leads to the outside. The active charge can be ignited through these openings 86 and 78 using external means (other electrical or pyrotechnic igniters).
[0052] The pre-tensioned position 48 of the
[0053] The action of the impact body 14 can also be reversed, i.e. the impact body 14 can be returned to the untensioned or only slightly pretensioned position shown in Figure 1. To do this, the user must securely hold the tensioning element 28 manually and then actuate the triggering element 60 in the manner described above until the impact body 14 is again aligned with the through opening 56 in the locking member 50 and can be moved through the through opening 56 in the locking member. The tensioning element 28 must then be pivoted back into the locked position 30 shown in Figure 1, in which position it holds the impact body 14 at a safe distance from the axial stop 46. The active body 2 is now deactivated again.
[0054] Furthermore, in this context, but also when tensioning the impact body 14 and the helical spring 16, it proves to be advantageous if a not too small clamping frictional force occurs between the boundary of the through opening 56 in the locking member 50 and the outside of the impact body 14, by means of which clamping frictional force can be prevented that the impact body 14 springs against the stop 44 when tensioning or untensioning if a finger of the user inadvertently slips off the tensioning element 28. Therefore, a clamping-type inhibition should preferably be implemented here, by means of which this can be reliably prevented. In this respect, it also proves to be advantageous if the through opening 56 is designed with a somewhat larger inside diameter than the outside diameter of the impact body 14. In the event of intentional release, this clamping connection can be released suddenly by manually actuating the release element 60.Finally, Figures 5 and 6 show views corresponding to Figures 1 and 2, but of an external visible side of the housing body 4. It can be seen that a longitudinal slot 64 extending in the longitudinal direction 18 and a transverse slot 66 are formed in one side or wall 62 of the housing body 4, so that the clamping element 28, as previously described, can be pivoted and displaced longitudinally together with the impact body 14.
