Abstract

A shot hollow metal ball as an entertainment appliance is disclosed. Said hollow metal ball can be shot toward target by an ejection gun, which is composed of gun barrel, two side barrels, breech, trigger, stand and ejection spring. Said breech uses a two-segment sleeve structure, a guide and a jam wheel for locking the compressed spring and shooting.

Description

The big gun ball

The present invention relates to a kind of new-type, popular recreation and competitive sport---apparatus and facility that the big gun ball is required.

In the present recreation and sports item, still there are not this type of sports apparatus and facility.

Purpose of the present invention: be exactly to design a kind of new-type used apparatus and facility of interesting strong project that can attract people extensively to participate in, to promote the human body physical and mental health.

The object of the present invention is achieved like this: by a kind of specially designed big gun that launches, pack special ball into back by the elastic force percussion, the target of shooting billiard table.Target number or the employing mode of keeping the score are come the comparison achievement to hit the target.Illustrated respectively below.

Launch big gun: constitute by gun barrel, slide cartridge, breechblock, emission spring, firing device and gun carriage etc.The big gun ball is packed into behind the gun barrel, pulls back the breechblock of both sides with both hands, and the spring in the compression bore as launch power, is pulled the plate machine of firing device behind the aiming target, and compressed spring energy is released, and ball is penetrated, and ball rushes at target along table top.

The ball that the motion of big gun ball is used is a kind of ganoid hollow metal sphere.Size is with 60mm～100mm (pressing the 80mm design) in the embodiment accompanying drawing, weight 100g～300g is advisable.

The target platform is the narrow fan-shaped ganoid horizontal long table that certain altitude is arranged.Its all each face all has backplate, at target platform far-end target is set.Some labels can be set on the target platform or place some spheroids (can be hollow metal sphere, ball, baton round or wooden shot).Goal as the big gun ball.

Owing to adopt and to launch big gun and go to hit this scheme of target, so preferably under the prerequisite, reach the desire that satisfies people's " shooting " in security with elastic force emission ball.Owing to spheroid is bigger, sight is strong, and suitable crowd is wide, can do popular recreation sexuality, can reach joyful and take exercises the promotion physical and mental health as the athletics project again.

In the embodiment of figure l, launch big gun and mainly constitute by gun barrel (1), slide cartridge (2), breechblock (3), firing device (5) (6), gun platform (8).Slide cartridge, breechblock and firing device all are bilaterals, and breechblock moves along bolt target slideway (4).

In figure (2) figure (3) of the foregoing description, the emission spring (11) that the big gun ball (10) in the gun barrel is being joined spring compressor (12) and spring base (14) withstands on the gun barrel front end.Breechblock is made of (3), guide gip (15), active pull rod (23), bolt cap (20), push rod spring (21) pull bar rope (22) bolt.Guide gip (15) is positioned at slide cartridge (2), can move together along slide cartridge and bolt handle etc.At this moment, the bolt target is in state anyhow, and active pull rod stretches into gun barrel, and the big gun ball sealing is closed.By tail end, gun barrel lateral wall indentation, there has card wheel (14) at the both sides slide cartridge.The solid spring spiral (7) of gun barrel afterbody is fixed spring base (13).As seen from the figure, breechblock is the nested structure double-deck inside and outside, and active pull rod is that bolt is inner core.

Figure (4) shows preceding each structure of emission and position relation: breechblock is pulled to breech along slideway, emission spring (11) is compressed, the tail end of guide gip (15) will block wheel (14) and clamp-on bore from indentation, there, big gun ball (10) is blocked (only having drawn side card wheel on the figure) by both sides card wheel, this moment, bolt was (3), around target pivot (18) flexing to the inside, the active pull rod (23) that is connect by link rod axle (19) makes the active pull rod front end withdraw from from bore simultaneously by flexing, and is ready for launching.Breechblock bolt handle shown in the figure, inside and outside two-layer all be one two the joint structure, inwardly flexing withdraws from active pull rod in bore.

Among Fig. 5 firing device by plate machine (5), hold handle (6), carry button shell fragment (27), draw button spring formations such as (28).Shown in figure (4) be synchronization, after launching spring and being compressed.This moment, the plate head fell into the plate trough (29) of guide gip rear portion downside, and guide gip (15) is braked, and top bolt spring (16) is simultaneously compacted.

Fig. 6 shows card wheel shape and structure, and card wheel (14) is made of metal, and wheel carrier (31) must be the shell fragment with favorable elasticity, to guarantee to block sliding certain mobility that has.

Fig. 8, Fig. 9 implement illustration: the essential structure requirement of big gun billiard table (or field).Billiard table is narrower fan-shaped microscler platform, and an end is the emplacement, and the other end is a target position.The emplacement is low, is convenient to big gun player seat or upright bit manipulation.All there is protective baffle plate (2) (3) (4) (5) (9) on covering of the fan four limits, play groove (8) and are higher than bullet pond (14), and big gun ball and target ball all can roll into by oblique return (6) and play the pond.Return can one or two, decides on the covering of the fan width, and target ball (10) is placed on the scrobicula of billiard table covering of the fan end, can be identical with big gun ball size or several different sizes are arranged.Fig. 9 board (11) that hits is another kind of target, and the target board is hung on the hack lever (13) by elastic drag rope (12), and target board bottom is fixed by the hook alive of table top.It is also unsettled to break off relations immediately after the target board is hit.

The emission mechanism of present embodiment: the first step, breechblock is pushed to gun muzzle and flexing bolt target, gun muzzle is slightly raised, put into the big gun ball after bolt stretching; In second step, both hands are held both sides bolt handle, pull to the breech end, and until putting in place, both sides card wheel locking this moment big gun ball is launched spring by maximum compression, and the plate head falls into the plate trough of guide gip; In the 3rd step, flexing, this moment, the active pull rod of locking big gun ball withdrawed from bore with the both sides bolt, by both sides card wheel locking big gun ball; In the 4th step, both hands are held both sides respectively and are held handle, run-home, and two fingers are pulled the biside plate machine simultaneously, and the plate head is stirred guide gip to front slide under the pulling together of top bolt spring, make guide gip break away from the card wheel, the resilience of card wheel, the big gun ball penetrates.

The initial velocity of big gun ball and range are decided by to launch elastic force, table top smoothness and the air drag of spring.The elastic force of emission spring can be divided into some ranks between 50N～300N, according to size and player's arm strength of field, shop, can freely change the emission spring of different elastic force.The degree of compression of spring requires not＜50%.Billiard table length can be decided according to the venue condition from several meters～tens of rice.
