Abstract

<P>PROBLEM TO BE SOLVED: To provide a bullet loading unit of an electric driven toy gun having a bullet acceleration function at the time of loading the bullet. <P>SOLUTION: In this unit, a spring for control operation is formed with a strip of thin plate spring which is fixed to an end at a bottom part of an outer cylinder for structuring the electric driven toy gun and a control protrusion in a stabilizing fin form is formed at another end. At the time of shooting operation, an inner cylinder pushes the control protrusion and a tip end of the outer cylinder shoves a plastic bullet into a barrel to conduct complete loading. Then, while straining force with repelling force of the spring, the inner cylinder is made to escape from the control projection and the plastic bullet is injected by pumping operation with the outer cylinder. In addition, an upper-lower line guide fixed to a main body of the gun is engaged and slid with an upper-lower control slider set at an appropriate position of the control operation spring. Just before shooting, the control protrusion fits in the inner cylinder from a bottom part of the outer cylinder and helps the inner cylinder to push the control protrusion. At the time of shooting, the upper-lower control slider detaches from the bottom of the outer cylinder. At the same time, the control protrusion slides just like escaping from the inner cylinder and the bullet is loaded in the same manner as the above. In the case that the control protrusion can not support the inner cylinder against repelling force of the spring, the inner cylinder escapes while straining the force and performing pumping operation with the outer cylinder and the plastic bullet is shot. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Industrial application fields

  The invention relates to an impacting device that accompanies acceleration of an electrically driven toy gun that can be enjoyed by firing plastic bullets.

  Conventionally, a plastic bullet filled in a magazine is pushed with a spring, and the lid that pushes and pushes the bullet is removed and crowned while synchronizing with the firing operation. For acceleration, etc., the idea is not far away, just stuffing the bullet into the barrel, and the mechanism is to move the air outlet of the outer cylinder back and forth at the outlet of the magazine with the firing operation, or The magazine entrance is linked with the gear that drives the gun via a spring, synchronized with the firing operation, pulled and returned with the gear and spring, and the magazine mouth is opened and closed and loaded etc. However, the former has a large device, so it cannot be used very much for small pistols, which is a big obstacle to miniaturization of electrically driven toy guns, and the latter is simple and incomplete, and can not be fully loaded. Yes, no For the both of the bullet acceleration it was not even the totally considering the fragments.

Problems to be solved by the invention

In addition to the above-described drawbacks, the method of moving the air outlet of the outer cylinder to be moved back and forth at the outlet of the magazine together with the firing operation, which is to be adopted in the impacting device with acceleration of the electrically driven toy gun of the present invention, has a serious defect. Explaining that, the firing operation started, the inner cylinder and the outer cylinder started to move together, the rear end of the outer cylinder hit the rear end wall of the gun itself and stopped, and at the same time the air outlet of the outer cylinder moved backward Open the magazine entrance, the plastic bullet jumps out and stops at the barrel mouth, only the inner cylinder advances further, the spring reaches the maximum displacement point, and when it reverses, the inner cylinder returns with the outer cylinder due to the repulsive force However, the outer cylinder has a tip at the air outlet that loses the force of the plastic bullet being pushed by the compression spring of the magazine, and cannot be pushed into the plastic bullet mouth, but it stops and only the inner cylinder moves forward. The tip of the outlet and the plastic When air leaks from the gap with the bullet and pump action cannot be performed and the inner cylinder reaches the inner wall at the tip of the outer cylinder, the inner cylinder pushes the outer cylinder, returns to the final point, and finishes the firing operation. However, plastic bullets only fall from the muzzle, do not fly at all, and do not use electric drive toy guns at all.
For this reason, in the impacting device with acceleration of the electrically driven toy gun of the present invention to be improved by improving such drawbacks, it is a problem to solve this, and the cooperative operation of the inner cylinder and the outer cylinder is performed. The plastic bullet must be fired at a bullet speed that is eye-catching, taking into account the complete effect of loading plastic bullets and taking into account the new effect of bullet acceleration.

Means for solving the problem

  A control action spring composed of a strip-shaped flat spring fixed at an appropriate position is installed at the tip of the outer cylinder at the center axis of the cylinder bottom, and a vertical control slider with a slide pin at an appropriate position is installed. In the rear end portion, a control protrusion having an upright wall and an inclined wall is formed by filling a soft structure in conformity with the shape. When stationary, hold the vertical control slider at almost the same height as the bottom of the outer cylinder and the control projection, start the firing operation, and when the outer cylinder starts moving together with the inner cylinder, slide the vertical control slider with the sliding pin. However, when the outer cylinder comes close to the bottom surface of the outer cylinder and the outer cylinder hits the structural base at the rear end, the up and down guides with the inclined surfaces are vertically moved so that the control projections fit into the outer cylinder control cutout grooves of the outer cylinder. It is fixed on the structure base of the gun itself so as to be in an optimum position for sliding with the control slider. Even if it hits the rear end wall of the gun itself at the rear end of the outer cylinder and stops, it moves to the inner cylinder that continues to move as if pressing the inclined wall of the control projection, and if it exceeds the upright wall, the control action spring The inner cylinder is pierced by both the inner cylinder control perforation and the outer cylinder control notch groove that overlap with each other, and the control projection is fitted. Returning together with the outer cylinder, the inner cylinder rear end lattice of the inner cylinder pushes the upright wall of the control projection, the inner cylinder pushes the outer cylinder, the inner and outer cylinders move together, and the outer cylinder moves to the air outlet At the tip, the plastic bullet already pressed by the escape cover is pushed into the barrel, and the inner cylinder is an outer cylinder that cannot be advanced first, so the upright wall of the control projection also does not move, and at the same time the outer cylinder moves, The vertical control slider is also slid with the vertical guide with a sliding pin and the height of the original control projection The control protrusion itself moves away from the inner cylinder rear end lattice to return to the inner cylinder end. The control projection is released from the restraint of the inner cylinder rear end lattice, the inner cylinder pops out vigorously, and a plastic bullet is injected from the air outlet with a tremendous momentum while pumping with the outer cylinder.

Action

An electrically driven toy gun that injects plastic bullets is fixed at an appropriate position on the front part of the outer cylinder with a control action spring consisting of a strip-shaped thin plate spring parallel to the axial direction on the bottom axis of the outer cylinder. At the rear end, the control projection is formed by an inclined wall and an upright wall filled with a soft structure conforming to the shape of a tail, and when the firing operation starts, the inner cylinder is compressed by the compression pressure of the pump action. After the movement of about 8 mm, when the rear end of the outer cylinder hits the structure base, at the same time, the control protrusion of the control action spring fits into the outer cylinder control notch groove, while the air outlet of the outer cylinder moves. Open the bullet outlet of the bullet housing so that the plastic bullets can escape easily, the plastic bullets jump out, stop at the escape lid, wait for the bullet loading operation, the inner cylinder continues to move, Pass over so that the rear end lattice of the inner cylinder crushes and crushes the inclined wall of the control projection After passing the upright wall, with the force of the control action spring, the control projection penetrates both the inner cylinder control perforations located overlapping the outer cylinder control notch groove, and after a momentary movement, Along with the return movement due to the repulsive force of the spring at the maximum displacement point of the spring of the electrically driven toy gun, the inner cylinder also begins to return, and the inner cylinder rear end lattice of the inner cylinder control bore of the inner cylinder is on the upright wall of the control projection Because of the upright structure, the outer cylinder pushes the inner cylinder by the upright wall because of the upright structure, and this action causes the tip of the air outlet of the outer cylinder to be already stopped by the escape outlet lid When the plastic bullet is pushed into the barrel, it will stop by pushing the injection packing, and when the inner cylinder stops moving, the inner cylinder corrects the repulsive force of a powerful spring. To endure, finally can not stand, control protrusion Beyond upstanding walls, hoarding the force of the spring to limit full intact, with tremendous force, by injecting air from the air injection port,

The invention will be described in detail with reference to the drawings with regard to the impacting device with bullet acceleration of the electrically driven toy gun. As shown in FIG. 1, when the trigger (1) is pulled, the gear mechanism (3) driven by the battery-operated motor (2) is moved via the rack (4) to the slide box (28), The linkage between the slide bodge (26) and the inner cylinder bodge (15) compresses the spring (14) loaded in the inner cylinder (9) to be fitted into the outer cylinder (10), thereby maximizing the displacement of the spring (14). At this point, the rack (4) is released from the last tooth of the semicircular toothed drive gear (8) constituting the last of the gear mechanism (3), and all the mechanisms are restored to return the inner cylinder (9). The outer cylinder (10) is also triggered by an electrically driven toy gun that injects air from the air outlet (27) of the outer cylinder (10) by the repulsive force of the spring (14) and injects a plastic bullet (6). When (1) is pulled and the firing operation is started, the inner cylinder bodge (15) By the engagement of the dovodge (26), the driving force of the motor (2) transmitted from the gear mechanism (3) to the rack (4) and the slide box (28) is transmitted to the inner cylinder (9), When the inner cylinder (9) and the outer cylinder (10) start to move simultaneously due to the compressive force due to the pump action and the rear end of the outer cylinder (10) reaches the structural base (24), the air injection of the outer cylinder (10) By opening the outlet (27) backward enough to allow the plastic bullet (6) to escape the bullet escape outlet (8) of the bullet housing (7), the plastic bullet (6) will pop out, The inner cylinder (9) continues to move as it is stopped by the escape outlet lid (13) and is fired, and is filled with the soft structure (29) in accordance with the shape of the tail blade, and the inclined wall ( 20) and an upright wall (23) to form the end of the control action spring (11). Thus, as soon as the inclined wall (20) of the control projection (21) fitted in the outer cylinder control notch structure (12) is pressed down to reach the upright wall (23), the final half-circular tooth is finalized. Due to the reversal of the spring (14) due to the release of the rack (4) from the drive gear (16), the inner cylinder (9) starts to return together with the outer cylinder (10), and the upright wall (23) that rises forward. As a result, the inner cylinder rear end lattice (17) of the inner cylinder (9) does not pass the upright wall (23) but pushes forward, so that the inner cylinder (9) pushes back the outer cylinder (10). The tip of the air outlet (27) of (10) abuts against the injection packing (18) of the barrel mouth (5) and press-bonds, and the plastic bullet (6) is pushed into the barrel mouth (5), and at the same time, The inner cylinder back end lattice (17) of the inner cylinder (9) 14) The inner cylinder rear end lattice (17), which has finally become unbearable, is filled with the soft structure (29) according to the shape so that it can withstand the repulsive force. Overcoming the upright wall (23) of the formed control projection (21), the inner cylinder (9) is instantly restored, while the outer cylinder (10) is pumped and a powerful spring ( 14) All of the repulsive force stored by shaving is transferred to the pump action, and a plastic bullet (6) is injected from the tip of the barrel at a tremendous momentum.
Another method with further improvements is to engage the sliding pin (29) of the vertical control slider (19) set in the control action spring (11) at an appropriate position of the structural base (24). For the firing operation of the outer cylinder (10) so that it is slid and kept at the same height as the control projection (21) away from the bottom surface of the outer cylinder (10) when stationary before the firing operation. Along with the movement to the structural base (24), the vertical guide (22) is appropriately adjusted so as to form a slope that is close to the bottom surface and fits the control projection (21) into the outer cylinder control notch groove (12). When the trigger (1) is pulled and the firing operation is started, the outer cylinder (10) and the inner cylinder (9) start to move together by the compressive force of the pump action, and slide up and down. The container (19) is also slid by the sliding pin (29) along the slope of the vertical guide (22). When the outer cylinder (9) starts to move toward the bottom surface and the rear end of the outer cylinder (10) hits the structural base (24), the outer cylinder (10) stops moving, thereby the outer cylinder (10). The air jet outlet (27) of the battery is fully opened, and the plastic bullet (6) easily jumps out of the bullet escape outlet (9) of the bullet feed housing (7) and is stopped by being pressed by the escape outlet lid (13). The plastic bullet (6) will wait in that position, while the inner cylinder (9) continues to move and the inclined wall (20) of the control projection (21) already fitted in the outer cylinder control notch groove (12). ) Is pushed forward to reach the upright wall (23), the upright wall (23) is restored by the spring force of the control action spring (11), and the inner cylinder control perforation ( 25) and the outer cylinder control notch groove (12), the upright wall (23) rises, At the end, during the firing operation, the spring (14) reverses at the maximum displacement point, the repulsive force causes the inner cylinder (9) to return, and the upright wall (23) is the inner cylinder of the inner cylinder control perforation (25). The inner cylinder (9) pushes the outer cylinder (10) by being pushed by the rear end lattice (17), and the outer cylinder (10) is already at the tip of the air outlet (27) and waits. The plastic bullet (6) is pushed into the barrel opening (5), and the tip of the air outlet (27) is pressed against the injection packing (18), and the inner cylinder rear end lattice (17) of the inner cylinder (9) The up-and-down control slider (19) climbs up the upright wall (23) as it tries to return to the height of the control projection (21) by the slope of the up-and-down guide (22), and the support allowance is increased. By reducing the amount, the repulsive force of the spring (22) cannot be withstood, and the corrected force is converted into a pump action. Of course, the inner cylinder (9) and the outer cylinder (10) are unthinkable so far by blowing air from the air cylinder outlet (27) climbing the outer cylinder (10) with tremendous momentum. Inject at speed. Thus, the impacting device with bullet acceleration of the electrically driven toy gun according to the present invention is capable of skillfully forming a position relative to the firing mechanism by the new device at the stage of firing operation of the plastic bullet (6), The bullet fires at an amazing speed with efficient operation.

The invention's effect

  As has been often described so far, the impacting device with bullet acceleration of the electrically driven toy gun of the present invention has invented an effective and efficient impacting device with a simple device from a point of view that has not existed before. In the conventional simple impacting device, the pump pressure by driving the inner cylinder is pushed by the spring deviating from the magazine, and the plastic bullet located in front of the barrel is pushed into the barrel and loaded. Only the inner cylinder moves forward, leaving the outer cylinder that can not be advanced, and the air flows out from the gap between the air outlet at the tip of the outer cylinder and the plastic bullet, and the pump between the inner cylinder and the outer cylinder No action was taken, and the plastic bullets were only spilled from the muzzle and were not used as a toy gun at all. Flaws This is an electric drive toy gun that is completely eliminated, simple and inexpensive, and has a full function when fired with bullets. The revolutionary function of accelerating bullets is sufficient to counteract the repulsive force of the outer cylinder spring. This gives the effect of a bow squeezed to the full moon, and as a result, the force of the spring is transmitted without waste to the pump action of the inner and outer cylinders, which in turn leaves the driving force of the motor. As a result, the control spring is fixed to the inner cylinder rear end lattice and the outer cylinder of the inner cylinder. The exquisite combination of the height that determines the degree of release with the control projection of the inner cylinder creates the mutual support action between the inner cylinder and the outer cylinder, creating the main effect of the impacting device with bullet acceleration of the present invention, and further Control slider and top and bottom Along with the guide, the release degree of the control projection can be newly created by considering the formation of the slope of the vertical guide with respect to the engagement sliding between the vertical control slider and the vertical guide, for example, The vertical control slider held at a height is first moved parallel to the plane of the outer cylinder, and the slope is set so that it drops quickly when the air outlet of the outer cylinder finishes the retraction operation. If there is formed, there is no excessively large wasteful resistance that damages the control protrusion, and a more powerful plastic bullet injection can be performed by a moderate pumping and a smooth pumping action without a break. Thus, the impacting device with bullet acceleration of the electrically driven toy gun according to the present invention helps to succeed in the electrification of a toy gun of the size of a small handgun, reduces the use of chlorofluorocarbon, and reduces environmental pollution. It has helped some of the prevention, and it has doubled the interest in play and the operation by bullet acceleration of the electrically driven toy gun, its novelty from its completely new viewpoint, and the effectiveness that produces various effects Is truly amazing and also proves its invention value.
