Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to rubber guns or catabalts, and more particularly, the present invention relates to rubber guns or catabalts, and more particularly, the present invention relates to rubber guns or catabalts, which are more accurate and sophisticated than currently known rubber guns; In one embodiment, a rubber gun or catabalt is provided that includes a reloading mechanism.

The improvement provided by the present invention is that the conventional bow (with the exception of q
(excluding crossbows), and also to compound bows, such as those described in US Pat. No. mL486.495. As used herein, the term "rubber gun" should be understood to include within its scope not only catapults, but also bows (other than curved) and compound bows.

[The problem that prior art and inventions seek to solve] The primitive rubber gun has been known for many years and consists essentially of two
It consists of a Y-shaped tool with loops of elastic material tied to the tips of two forked sections. This rubber gun has significant disadvantages in that it is prone to inaccurate aiming and it is difficult to pull the elastic ring to give the projectile an accurate trajectory.

One attempt to overcome this drawback by providing a guide path for the bullet was made in U.S. Pat. No. 4.386.5.
It is described in No. 98. However, this prior art catapult uses a magnetic device to hold the bullet until it is fired by a sling. Obviously, some of the sling's energy is used to overcome the magnetic forces holding the bullet in place.

Additionally, this prior art catabalt is limited to magnetic or magnetizable projectiles. There are two further drawbacks. That is, in the first preferred embodiment of the above patent, the bullet is fired from the barrel, and some of the energy imparted to the bullet is dissipated by impact and friction between the bullet and the barrel wall. It can be predicted. In a second embodiment, a series of telescoping tubes are used, with the bullet running outside, but as acknowledged in the specification, some accuracy is sacrificed.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a rubber gun or catabalt which significantly improves the drawbacks of the prior art as described above.

[Means to solve the problem]

According to the present invention, in order to achieve the above object, the present invention includes: an elongated guide device, a main body portion including a handle and attached to the guide device, a strong pulling unit slidably attached to the guide device, and a strong pulling unit. a carriage that is attached to the guide device between the and the main body portion and can slide on the guide device independently of the strong pull unit; a bullet rest disposed within or on the carriage; a strong pull unit; A rubber gun for firing a bullet is provided that includes a power sling coupled to a carriage, a catch for holding the power sling in a ready-to-fire position, and a trigger device for releasing the catch.

[Actions, effects and modes of the invention]

In addition to being more accurate, the rubber gun of the present invention allows for the use of a wider range of bullets and does not require selection based on magnetic properties. Therefore, the rubber gun of the present invention is
For example, it can be used with plastic bullets or darts. In a further preferred embodiment,
The rubber gun of the present invention also has a quick reload facility.

The present invention also exhibits significant advantages in the field of archery in general. Currently, conventional bows are the most popular archery equipment, and bows are almost no longer standard bows. -Many archers prefer traditional bows for the enjoyment of the physical involvement of drawing and shooting an arrow. However, in competitive archery, there is no uniformity of bows or arrows, and different competitors are allowed to use bows of varying weights, with arrows of varying weights, lengths, and diameters.

The present invention is suitable for types of competition in which all competitors use the same shooting equipment and projectiles of the same size and weight, whereby the skill of each competitor, rather than any particular combination of equipment, is the key. Are suitable.

The rubber gun of the present invention allows steel balls or darts (as used herein, the term "dart" refers to arrows) to be released from the shooting tool by releasing the clasp, rather than firing the bowstring with the fingers as in the case of a conventional bow or catabalt. and the like). Unlike arrows in conventional bows, the rubber gun of the present invention is capable of firing bullets (projectiles) such as This makes it easier to use than traditional bows.

Furthermore, the rubber gun of the present invention has a distinct advantage over previous traditional bows since it does not need to be hammered in preparation for firing, as with bows, which poses the risk of accidental firing. . Getting the bow ready to fire requires a certain degree of mobility that is not normally possible, for example, for people with disabilities who often desire to enjoy archery as a sport or competition. In most cases, the firing position
> requires the user to stand and place his weight on the striking mechanism. Such mobility is not necessary at all in the case of the rubber gun of the present invention, which allows the user to prepare and fire the gun without having to stand.

Furthermore, the rubber gun with the quick reloading device of the preferred embodiment of the present invention becomes attractive to users with disabilities.

The elongated guide device may, for example, be a rail of suitable cross-section with respect to the force pulling unit and the carriage, so that the force pulling unit and the carriage are held on the guide rail during operation of the rubber gun, and the force-pulling unit and the carriage are held on the guide rail with a minimum It slides smoothly with “play”. In one embodiment, the elongate guide rail has a "T"-shaped cross-section, and the force pull unit and carriage each have a rail guide portion that carries a crosspiece portion of the "T". In another embodiment, The guide rail has a "C"-shaped cross-section, and each strong pull unit and carriage has a bulb extending radially from the center of the guide rail to retain the strong pull unit and the carriage, respectively, on the guide rail. Other shapes of the guide device will be apparent to those skilled in the art and any guide mechanism is applicable.

The body portion can be integrated with a pistol grip or similar shaped handle. Most conveniently, the trigger is placed close to the handle so that it is operated by the index finger of the hand gripping the handle.

The force pulling unit can take various shapes.

When the rubber gun of the invention is of the catapult type, the force-pull unit preferably has a handle that, in use, depends below the guide device, so that the user can use one hand (e.g. the right hand) to gripping the handle of the main body with the other hand, the force pulling unit can be pulled or pushed away from the carriage, thus tensioning the rubber gun for firing when the carriage is in the ready-to-fire position. The rubber gun of the present invention can be fired by either right-handed or left-handed users, which is further appreciated as an advantage over prior art archery equipment of the rubber gun of the present invention.

When the rubber gun of the present invention takes the form of a bow, the arm of the bow forms part of the powerful pull unit.

An adjustable stop collar may be mounted on the guide device so that the stop can be locked into position on the guide device. In use, the power pull unit is pulled until it reaches the strike spring, the power sling in the ready position is released through the catch, and the bullet is fired. By using an adjustable stopper, the rubber gun of the present invention can be adjusted for different arm lengths and forces.

The carriage is mounted on a guide device between the force pulling unit and the main body part. The power sling is connected to the carriage by suitable means.

Preferably, said connection is a permanent connection in order to ensure that the tension in the sling forming the loop between the carriage and the force pulling unit is equal.

Of course, even in the case of a permanent connection, the power sling should be replaceable when worn or JJ II.

A bullet rest in or on the carriage is configured to receive a bullet and retain it in or on the bullet rest at least until the rubber gun is fired. The shape of the bullet rest depends on the shape and nature of the bullet to be fired.

If the bullet is a steel ball or a spherical pellet, the bullet holder may form a spherical recess for receiving such a bullet.

If the bullet is a dart, the bullet rest may include a support for the body of the dart, and preferably the bullet rest holds the dart in place on the carriage until the carriage reaches the end of its exit path. including the means to maintain it. These means may consist of pivoting tongues which are themselves located in slots provided for this purpose in the dart body.

The releasable clasp is operated by a trigger mechanism, preferably including a release lever configured to release the clasp and release the power sling.

The fastener shall retain the power sling in any suitable manner. For example, the fastener may be operative to fasten the carriage to which the power sling is attached. However, in the case of a substantially spherical bullet, the clasp actually supports the bullet when it occupies the pad, and the clasp cannot hold the carriage when the pad is empty. It is preferable to design the carriage so that: In this way, dry firing of the rubber gun is prevented.

The power sling preferably takes the form of a pair of power bands, each connected at one end to the carriage and at the other end to the force pulling unit.

This embodiment is particularly suitable when the rubber gun of the invention takes the form of a catabalt. When the rubber gun of the present invention is in the form of a bow, a power sling is constructed from the bow and the bow string.

It is preferable to insert a damper between the force pulling unit and the carriage, so that when the carriage is released under tension, this does not strike the force pulling unit, but rather prevents it from being spring-loaded. contact with a shock absorber configured to reduce the impact by other means.

Preferably, the rubber gun of the present invention also includes a magazine and means for feeding bullets from the magazine to the bullet rest.

Means may also be included to ensure that no ammunition is dispensed from the magazine unless the magazine is in proper position relative to the magazine.

If the rubber gun of the invention includes a magazine, the shape of the magazine and the manner in which the bullets are fed to the bullet rest depend to a large extent on the nature of the case. For example, if the bullet is a steel ball, the magazine may be gravity-fed, and a breech plug (located at the breech) to ensure that the bullet is not fed from the magazine unless the bullet rest is in the correct position with respect to the magazine. It is preferable to provide a closure body).

If the bullets are darts or the like, they can be stacked in the magazine and biased against the bottom of the magazine by a spring. Each dart may be fed into the bullet rest by pressure applied by a spring until the dart is placed on the bullet rest and the tongue of the bullet rest is disposed in a slot in the dart body. The tongue is actuated for this purpose by a catch so that the dart can be released when the tongue descends and leaves the slot during firing of the rubber gun.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to some preferred embodiments shown in the accompanying drawings.

First, referring to FIG. 1, the rubber gun 1 is powered by a pair of power bands 2 connected to a carriage 3 by an arm 4 (see FIG. 3) and to a powerful pulling unit 5 by an arm 6 (see FIG. 6). Has a sling.

The carriage 3 and the powerful pulling unit 5 are mounted on a guide rail 7 having a "T"-shaped cross section as shown in FIGS. 4 and 5.

The force pulling unit 5 has a handle 8 for pushing or pulling the force pulling unit 5 along the guide rail 7 away from the carriage 3. The adjustable pull stop collar 9 can be locked in a desired position along the guide rail 7 by means of a set screw 10, thereby allowing the user to:
It can be adjusted to suit the length of his arm and ensures that he applies the same amount of force each time he pulls the rubber gun.

The body portion 11 has a release lever 13 configured to release the handle 12 and the catch 14 (see, for example, FIG. 2). The magazine chamber 15, which is integral with the body part 11, has a cheek rest 16. Above the magazine chamber 15 there is a rear peep sight 17 and an adjustable sight spindle 18 (see Figures 1 and 7).
is installed. The front sight 19 is integrated with a pull stop collar 9 mounted on the guide rail 7 as shown.

Now, referring to Figures 2, 3, 4, and 5,
Carriage 3 shown mounted on guide rail 7
has a bullet holder 20 configured to receive a spherical bullet 21, for example a spherical bullet made of metal, plastic or rubber. For purposes of illustration, the bullet 21 is shown separated from the bullet rest 20. As is clear from the following explanation, when the clasp 14 is in the firing preparation position, the bullet 21 is
The clasp 14 holds the carriage 3 and power band 2 in the ready-to-fire position. Rotation of the catch 14 about the pivot bin 22 (by use of the release lever 13 of FIG. 1) allows the bullet 21 to be fired.

The recess 23 of the carriage 3 is configured to cooperate with a tail plug, as will be explained later.

To prevent dry firing, the carriage 3 has a slot 24 (shown in FIG. 5) into which the fastener 14 is inserted when there is no bullet in the bullet rest 2o.

4 and 5 show the carriage 3 mounted on the guide rail 7, which has a rail guide portion 25 (see FIG. 5) for retaining the carriage 3 on the guide rail 7. FIG.

FIG. 6 illustrates an optional shock absorber that may be included in the rubber gun of the present invention. The shock absorber 26 has a spring retaining pin 30
Powerful pulling unit 5 by two springs held by
It has a buffer stop 27 connected to an extension 28 of the buffer. After release, the carriage 3 strikes the buffer 26 at the contact point 31. This prevents further advancement of the carriage 3 and the bullet 21 (not shown in this figure) continues to be directed towards the target by its momentum. For simplicity of illustration, power band 2
has been removed from this figure.

FIG. 7 shows another embodiment of the rubber gun of the present invention optionally equipped with reloading equipment. The magazine chamber 15 shown in FIG.
A gravity-fed magazine 32 with 3 is employed. Bullet 2
1 are fed into the carriage 3's bullet holder 20 one at a time via the breech channel 36. The sliding breech plug 37 is the breech chamber 38
, and is biased toward the carriage 3 by a tail plug spring 39 fixed by a spring retaining pin 40. When the catch 14 is released, the power band 2 contracts and the carriage 3 is propelled away from the tail plug 37, which then travels in the same direction until the tail plug stopper 41 strikes the contact portion 42.

In this position, the tongue piece 44 of the tail plug 37 (see FIG. 9)
closes the breech path 36 and sufficiently prevents the bullet 21 in the bullet travel path 33 from passing through the breech path 36. By pulling the handle 8 of the force pulling unit 5 towards the handle 12 of the body (the buffer 26 engages the carriage 3 at the contact point 31 of the buffer) the carriage 3 is moved over the catch 14 into the ready firing position. When pulled, the tail plug 37 moves its position,
The tongue 44 is withdrawn from the breech channel 36 and the next bullet 21 drops into the bullet rest 20. In this state, the tongue piece 44 is pushed into the recess 23 of the carriage 3 (see FIGS. 2 and 3) and helps the tail plug 37 to be placed behind the carriage 3.

To fire the rubber gun again, the handle 8 is pushed away from the handle 12 until it reaches the stop collar 9, and the release lever 13 is operated to deflect the catch 14 and the carriage 3 is released, as explained below. and is driven forward until it hits the contact point 31 of the shock absorber 26, as described above.

Details of the trigger mechanism are illustrated in FIG.

The catch 14 is tensioned by a spring 47 which is secured by a pin 48. The roller 45 is rotatably attached to a shaft 46. The release lever 13 pivots around the bin 49. When the power sling is in the ready-to-fire position, the carriage 3 pushes against the catch 14, which pivots around the pin 22 and simultaneously engages the roller 45. When the release lever 13 is pulled toward the handle 12 of the main body,
The roller 45 releases the catch 14, which then pivots further until it abuts the contact 54, at which time the carriage 3 is released from the catch 14. Release lever 13
is biased to its upper position by a spring 50 and a pin 51, and the retraction of the release lever 13 is limited by a release lever stopper 52.

When the carriage 3 is in the form of the embodiment of FIG. 10 or FIG.
can be deflected into the recess 53 by the bottom of the recess 53 . carriage 3
is in the form of the embodiment of FIGS. 2-5, and when the carriage 3 is pulled past the catch 14 toward the ready-to-fire position, the catch 14 passes through the slot 24 and the bullet 21
Preparation for firing is not completed until the bullet holder 20 is occupied.

In either case, the linear side surface 5 of the fastener 14
5 and the engagement of the catch 14 with the roller 45 as described above prevents accidental release of the carriage 3.

Tension adjustment screw 56 serves to adjust the amount of force required to release fastener 14 to suit individual tastes.

Returning now to Figures 10, 11 and 12, the carriage 3 is designed to carry a Dart 64 (Figure 12) or similar bullet, and as part of the bullet rack,
It has a firing tongue 57 configured to be placed in a slot in the dart body as described below. In the firing position, the firing tongue 57 can pivot around the pin 58 until it reaches the stop 74, and in the retracted position the firing tongue 57 also reaches the stop 74. can rotate around the bin 58 up to

The dart 64 in FIG. 13 includes a dart body 69, a pointed end 70,
It has a plurality of blades 71, a stem 72, and a slot 73 passing through the dart body 69. (As a modification, the dart 64 can be made to have a recess on the lower side of the dart body 69 instead of having the slot 73 passing through the six dart bodies.) When moved to the firing position, the catch 14 pushes the firing tongue 57 upward to the firing position. The firing tongue 57 then either manually places the dart on the carriage 3 (FIGS. 10 and 11) or in the magazine chamber 15 {! By supplying darts from the storage tank (FIG. 12), the darts are placed in the slots 73 of the dart body 69. (In the dart modification example described above, the firing tongue piece 57 engages with the recessed portion on the lower side of the dart body 69.)
When the catch 14 is released by pulling the release lever 13, the carriage 3 is released and propelled. The force being applied to the carriage 3 by the power band 2 causes the dart 64 to remain in place on the carriage 3 until the carriage 3 hits the contact point 31 (see FIG. 6) of the shock absorber 26 and comes to its end of travel. The firing tongue piece 57 is held at the firing position while maintaining the firing position.

The Dart magazine illustrated in FIG. can. A locking catch 60 secures the magazine cover 62. Compression leaf spring 63 supports the top of the stack of darts 64 in the magazine, and darts 64 are maintained in a stacked condition by dart tip guide 66 and dart vane guide 67. Dart 6 by leaf spring 63
4 is biased toward a leaf spring stop 65 on the slotted magazine chamber bottom 68.

When the rubber gun is in the ready-to-fire position, the carriage 3 is pulled along the guide rail 7 in the direction of the handle 12, the catch 14 pushes up the firing tongue 57 as already explained, and the carriage 3 pushes up the firing tongue 57. adjust its position under the force applied by the power band 2 until it is placed in the slot 73 of the dart body 69. In this position, the dart 64 to be fired is out of alignment with the remaining darts 64 in the magazine, as shown in FIG. By then releasing the catch 14 via the release lever 13,
The carriage 3 is driven forward until it strikes the buffer 26, and the firing tongue 57 is retracted until it stops against the stopper 74, which prevents the bottom of the firing tongue 57 from protruding above the carriage 3. , and the dart 64 is fired as described above.

The arrows or darts that can be fired from the rubber gun of the present invention can be much shorter than the power stroke of the rubber gun;
It would be appreciated as a further advance improvement over traditional bows, which require longer arrows than the bow's power stroke.

Furthermore, it is to be understood that the description of the invention in connection with the drawings is for purposes of illustration only and is not intended to limit the scope of the invention.

For example, it will be apparent to those skilled in the art that the power pull unit 5 of the figures can include a pair of bow arms. Furthermore, the powerband 2 can also be replaced by a bow and bowstring, preferably permanently affixed to the carriage 3 via the arm 4. Similar adjustments can be made to adapt the principles of the invention to compound bows.
