Description

SPECIFICATION Toy pistol for the successive firing of detonator capsules The invention relates to a toy pistol for the successive firing of detonator capsules provided with a spring-loaded cock which has a firing pin and which is cockable and releasable by means of a trigger lever, wherein the firing pin hits respective detonator charges of a plastics detonator strip conveyable in a guide channel running through the body of the gun.

From DE-PS 12 75413 a toy pistol is known wherein the firing pin for igniting the detonator charge of the detonator capsule is arranged at the rear end of the tubular barrel. This barrel is biased by a leaf spring to carry out a resetting movement in the direction towards the grip of the gun and is fitted at approximately its middle section with an entraining cam engaged by a spring-loaded trigger lever. By means of the trigger lever the barrel together with the firing pin can be pushed forward against the force of a leaf spring, whereby after exceeding the pressure point, the trigger lever releases the barrel with the firing pin and bounces back under the effect of the spring force of the leaf spring and hits a detonator capsule.The movement of the trigger lever is transmitted through the barrel to the firing pin arranged at the end of the barrel. The plastic detonator strip is located in a magazine housed in the grip of the gun and can be advanced into the position required for the firing of the detonator capsule by a to-and-fro movement of the barrel actuated by a two-armed lever, wherein this lever acts upon the plastic detonator strip from one side and eccentrically, whereby in addition to a displacement force, a torque is exerted on the plastic detonator strip, which could cause jamming of the plastic detonator strip in its guide channel. In addition to the firing pin a cutting blade for severing and ejecting the detonated capsules is arranged at the rear end of the tubular barrel.Particularly in embodiments where the tubular barrel is encased in the gun body, the detonating movements are not visible from outside.

A cock formed on the gun body is merely a dummy and does not participate in the firing movements.

in another known toy gun, although a cock fitted with a firing pin is used, yet the firing pin is arranged wholly inside the gun body and cannot be seen from the outside. The advance of the plastic detonator strip toward the barrel in a guide is actuated by a spring elementformed as an extension of the trigger lever. This spring element acts also from one side and eccentrically on the plastic detonator strip; thus jamming of the strip in its guide cannot be excluded in this known embodiment. In addition, in this known embodiment also a cocking arrangement is moulded on the gun body and so cannot participate in any firing movement.

The aim of the present invention is to provide a toy gun (pistol) of the above-mentioned type wherein the cock fitted with a firing pin can within the range of its motion move out of the gun body and by the movement of the trigger lever not only the cock, but also the advance of the plastic detonator strip may be operated safely and without jamming, while the firing and transport mechanism consist of the lowest possible number of components.

The aim of the invention is achieved in that the trigger is arranged at a distance from the cock but is connected to it by a transmission rod which includes entraining members which, during cocking in the direction of feed, engages cams on both sides of the plastic detonator strip. Since it is possible to place the cock at any desired position spaced from the trigger lever, the external configuration of the toy gun is freely selectable while on the other hand the symmetrical engagement of the entraining members with cams on both sides of the plastic detonator strip assures its jam-free advance. The movement of the cock can be seen from the outside at each firing and the toy gun looks like a real weapon.

The entraining members may advantageously be integrally connected to the transmission rod, the entraining members together being of a fork shape and developed in the form of tongues of the transmission rod produced by a chipless forming technique. In this way, simple, low-cost components for firing and advancing the plastic detonator strip may be produced.

For a precise control of the advance of the plastic detonator strip and the ignition strike of the cock one end of the transmission rod may be connected by means of a pivot pin to the trigger lever and its other end to an entraining cam of the cock via a sliding pawl; the transmission rod is provided with a lifting cam surface sliding on a fixed point of the gun body to release the cock after termination of the cocking movement.

To ensure that after firing the transmission rod is re-engaged with an entraining cam of the cock, in a further constructional feature of the invention the connecting rod is biased to resetting by a force storage device the biasing action of which is directed approximately towards the fixed point of the gun body co-operating with the lifting cam surface.

In one of the above-described embodiments of the invention the fork body is rotatably journalled on the transmission rod such that towards the end of the resetting movement the tips of the fork can slide into the 'ready' position over the feed cams engaging below the plastic detonator strip. Since the fork body is preferably an angularly displaceable flat piece journalled on one angled shank of the transmission rod, it can carry out angular movements that are limited by a nose on the fork body projecting into a window aperture in the transmission rod, and so simple, readily producible and assemblable components may be produced.

In an embodiment provided with a pivotable fork body, the tips of the fork are chamfered to facilitate a more reliable engagement of the cams on the underside of the plastic detonator strip at the start of the advancing and cocking movement of the cock.

In order to ensurethatthe plastic detonator strip remains in the grip of the gun invisible from the outside until the last detonator capsule is fired, according to another constructional feature of the inven ron, the strip guide is arranged in the grip, optionally as an infeed channel arranged in an insertable magazine and an outlet channel located in the barrel of the gun, which channels are connected together by an approximately quadrant-shaped channel piece, while the outlet channel exits from the barrel of the toy pistol in the region of the gun-sight.

Two preferred embodiments of the invention are illustrated in the drawings and are described hereafter in greater detail. In the drawings: Fig. 1 shows the toy pistol according to the invention in a side elevation partly broken away, before actuation or the trigger lever; Fig. 2 shows the part of the toy gun containing the firing mechanism in aviewsimilarto Fig. 1, wherein the trigger lever has been squeezed to just shortly before the pressure point; Fig. 3 shows a part of the toy gun iilustrated in Fig.

The pistol body formed from a grip or butt 10 and a barrel 11 consists of two essentially symmetrical parts made of thermoplastic material in which are contained the cavities and seats for supporting and guiding mechanical components. A stationary shaft oraxle 12 is arranged in the gun body in the lower region of the barrel 11 on the side contiguous with the grip 10 and a trigger lever 13 is pivotaily journalled on the axle. A trunnion 14 is located on the part of the trigger 13 which protrudes into the gun body and pivotally journals a transmission rod 15. The transmission rod 15 is essentially of an angle shape, with a longer shank 16 and a shorter shank 17. A pressure plate 18 is fitted on the top of the longer shank 16 on which plate a compression spring 20 journalled in a recess 19 of the gun body exerts a resetting effect.The lower end of the shorter shank 17 of the transmission rod 16 is provided with a chamfered sliding pawl 21 acting on a cock 24 rotat ablyjournalled on a pin 23 fixed in the gun bodlf behind an entrainment cam 22. The cock 24 is of approximately angle shape, one shank of this angle being journalled on the pin 23 and the other shank being formed as a firing pin 25 In the region of the junction of the two shanks the cock 24 has a lug 26 projecting through an opening 27 of the pistol body.

The shank of the cock 24 which is fitted with the cams 22 is provided with a lateral recess in the vicinity of pin 23 in which is arranged a torsion spring 28 that surrounds the pin 23. The free leg of the torsion spring 28 is fixed on the one hand in a bore 29 in the cock 24 and on the other hand on an abutment 30a of the gun body. The torsion spring 28 acts on the cock 24 in such a way that after release by the transmission rod 16 it is rotated anti-clockwise and the tip of the firing pin 25 hits one of the detonator capsules 30 of the plastic detonator strip 31.The detonator capsules 30 are connected together and to the strip 31 by way of webs 45 which are provided at their lower part with feed (advancing) cams 32 projecting from both sides of the strip transversely to the longitudi nal direction of advance of the plastic detonator strip 31, as illustrated particularly in Figs. 4-6.

The shank 17 of transmission rod 16thatcan be connected to the cock 24 is provided with entraining members 46 for engaging the feed cams 32 of the plastic detonator strip 31. In the embodiments illustrated in Figs. 4-6 these entraining members 46 are integral with the shank 17 in the form of tongues 47, 48 which together have an approximately forkshaped configuration for surrounding the detonator capsules 30.While the tongue 47 is formed by an outwardly bent wall portion of the shank 17, the tongue 48 is located on an angled part 49 of the shank 17 and is in turn bent into a position corresponding with the tongue 47, the dimensions and the angular position of the tongues being chosen in such a way as to enable the unimpeded introduction of the entrainment members between consecutive pairs of feed cams and their advancing as well as the sliding off of the entrainment members from the advanced pair of feeds cams.

To form the entrainment members 46 in the embodiments illustrated in Figs. 7-9, the shank 17 connectable to the cock 24 is provided with an ang led limb 33 on which the fork body 34 made of a flat piece is journalled for angular movements. This fork body 34 is provided with a fork shank or tine 35 for embracing a respective detonator capsule 30, which tine is chamfered on its tip in order more reliably to engage the feed cams 32 of the plastic detonator strip 31. To support the fork body 34 on the short shank 17 of the transmission rod 16 and to limit its angular movement, the rear end of the fork body 34 isjournalled with a clearance in slots of the angled limb 33, while the shank 35 adjacenttothe shank 17 of the transmission rod 16 is engaged via a nose 39 in a window aperture 40 of the transmission rod 15.

In the present embodiment, to release the entrain ing cam 33 on the cock 24 for an ignition strike on the one hand and to advance the plastic detonator strip 31 on the other hand, a curved lifting cam surface 37 is provided on an inner corner segment between the shanks 16 and 17 of the transmission rod 15; the surface slidably bears on a fixed point 38 of the gun body. Proceeding from one of the positions of the trigger mechanism illustrated in Figs. 1,4 and 7, by pivoting the trigger lever 13 anti-clockwise about the trunnion or pivot pin 14, the transmission rod 15 is pulled forward against the spring 20.This causes the lifting cam surface 37, which in the present embodiment has a two-stage inclination, to slide upwards over the fixed point 38 and by doing so, to displace the cock 24 clockwise whereby, due to the upward movement caused by the lifting cam surface 37 the slide jaw 21 of the entraining cam 22 is unlocked at the so-called pressure point.

Figs. 2, 5 and 8 illustrate a position shortly before the release of the entraining cam 22 on the cock 24.

Simultaneously with the forward movement of the transmission rod 15 the entraining members 46 engage in the gap between two pairs of superposed feed cams 32 and get into position to push the next pair of transport cams 32 upwardly. The conditions are selected in such a way that when the pressure point is attained, i.e. when the slide pawl 21 has slid off from the entraining cam 22, the next undetonated capsule 30 arrives in a position in which the firing pin 25 of the backward bouncing cock 24 can strike the capsule 30. This moment of firing is illustrated in Fig.

3. As soon as the trigger 13 is released, the tensioned compression spring 20 pushes the transmission rod 15 back into the position illustrated in Figs. 1,4 and 7.

To advance the detonator capsules 30 of the plastic detonator strip 31 to the point of firing an inlet guide channel 41 can be formed inside the grip 10 of the gun body, running along the longitudinal axis of the grip 10 and may be formed by a magazine (not shown) that can be pushed into the grip 10 of the toy gun. The section of the plastic detonator strip 31 containing the already detonated capsules is pushed into an outlet guide channel 42 extending in the barrel 11 of the gun body and connected to the inlet channel 41 by a quarter-circle-shaped channel section 43. In this embodiment the firing region is located in the arcuate channel section 43. The outlet channel 42 exits from the barrel 11 immediately before the gun-sight 44 situated at the end of the barrel 11 and its length is so chosen that after the firing of the last capsule, the beginning of the plastic detonator strip 31 just leaves the barrel 11.

As already mentioned, the illustrated embodiments are mere examples of realizing the invention which is not restricted to these embodiments: many other embodiments of the invention are possible.
