SPECIFICATION

This invention relates to an accessory for a long firearm, and more particularly to a sling ass embly for rifle , shotgun or similar firearms .

Conventional sling for rifles have their rear 5 swivels attached to the toes of the rifle butts and their

^• front swivels to the bottoms of the fore-ends of the rifle stocks _* The main purpose of this kind of sling assembly is to carry the rifle at the back of a person during parade or long hike.

10 In target, practice , when the shooter is in prone , sitting or kneeling position ^* , the sling helps to make a rigid brace for the arm that supports the rifle under the barrel _* However, in combat or in fast shooting, the same sling becomes superfluous and cumbersome _* -t_ 5 In case of. emergency such as during ambuscade , it . takes a long time and deliberate movement to untangle the* sling from his shoulder and put the rifle at firing position _* Precious seconds are lost and the delay may even cost his life. 0 Some European soldiers made some improvement by attaching the swivels at the sides of their sub- machineguns so that they can fire the same from waist or hip level during emergency with the slings still attached at their shoulders . But firing the ' firearms 5 from the hips ^* or waist requires a lot of practice and consumption of considerable quantity of ammunitions . Some users of submachineguns have developed the tendency to "walk" the bullets towards the targets , hitting a target beyond ten meters from the waist or hip level becomes a guesswork.

The pres ent sling ass embly , as embodied in this invention , allows a rifle , shotgun, or even sub- machineguns , to be carried in a ready position at a waist or hip level parallel to the ground> 'without tiring the arms of the soldier. At this ready position, the firearm can be fired instantly from the waist, hip and more' importantly mounted at the shoulder and fixed at eye level for accurate firing or shooting.

The obj ect therefore of this invention is to provide a sling ass mbly for a rifle, shotgun or similar firearm that considerably increases the usefulness of the- fire¬ arm _*

Another object of this invention is ^" to provide as. sling assembly for a rifle, shotgun or similar firearm, which allows said firearm when carried, while walking, sitting- or in standing position , to have its.- slingr secured across the shoulder of the soldier or hunter and to. hold the grip comfortably by one hand_.

Another bject of this invention is- to provide a sling assembly for a rifle, shotgun or similar firearm which allows- said firearm, to be carried conveniently in ready-to-fire position by securing its sling across the shoulder of the soldier or hunter with the firearm parallel to the ground at hip or waist level at his left or right side and allowing him to hold the firearm grip with, only one hand, while its- weight is borne through the shoulder, thus preventing undue strain on his arms .

Still another object of this invention is to provide a sling ass embly for a rifle , shotgun or

similar firearm which allow said firearm to be fired instantly from the waist or hip level , if necessary , but more importantly moved instantly upward from the waist or hip level and mounted at the shoulder and fired at eye level with considerable accuracy. The sling as sembly automatically guides the butt to the correct point at the shoulder.

A further object of this invention is to provide a sling ass embly for a rifle, shotgun or similar firearm which allows a soldier or hunter, while sitting down or relaxing, to place his- firearm at the back , but ensuring that he can immediately put said firearm in ready-to- fire position in cas e of emergency.

A* further object of this invention is to provide a sling assembly for a rifle , shotgun or similar firearm whose sling portion does not only aid the shooter in steadying his shots in conventional or target positions , but also, firing in full automatic in actual combat.

Other objects and advantages of this invention will become clear and apparent as this specification proceeds .

Referring to Figs . 1 , 2 , 3 , 4 , 5 , 6 , and 7 , the sling assembly, which is the basic form of the invention, includes a rear portion ^" of the butt 1 of a firearm stock , a fore-end 2 of the same stock , a rear swivel 3 pivotally attached between the toe and the heel of the butt 1 , a front swivel 4 pivotally attached to the fore-end 2 of the firearm stock and a sling 5 of considerable length whos e ends are connected to the rear and front swivels 3 and 4.

Specifically , the rear swivel 3 has a U shape and provided with an elongated opening or slot 3a at its outer and portion through which the sling or strap

s nser o p v n ro s pp ng s ew se. The two ends portions of the rear swivel 3 are turned inwardly forming short shafts 3b. Forming parts of the rear swivel are two washers 3c with small screw holes . The swivel 3 is pivotally ^* attached to the butt 1 of the firearms stock , between its heel and toe, by securing its short shafts 3b through the center holes of the washers 3c which are in turn fastened to the sides of the butt 1 by suitable wood screws and allowing the swivel 3 to pivot or swing at about 180 degrees from the toe to the heel and . vice versa _*

The front swivel 4 has a T shape with elongated opening or slot 4a at its enlarged outer or ^' and portion through which, the sling or strap 5 is inserted. The front swivel 4 has also at its pivot and a hole 4b for rotatably securing the front swivel 4 to the side of the fore-end 2 of the rifle stock by means of a screw or bolt 4c and a pair of washers 4d. If the fore-end 2 of the rifle stock is made of wood , a wooden screw 4c may be us ed. However, if the fore- end 2 is made of plastic or nylon material , a bolt 4c , together with metal strap e and nut 4f may also be used, as illustrated in Figs. 5 and 7. Inasmuch as the rear swivel 3 is pivotally connected to the butt between its toe and heel , and the front swivel 4 is rotatably attached to one side of the fore-end 2 of the firearm stock it becomes obvious that the sling 5 can easily be placed to the barrel side or to the stock side of. the firearm , as illustrated in Figs. 1 and 2. BURS _____P

The s econd embodiment of this invention is basically similar to the first embodiment , except that this sling ass embly , as shown in Figs . 8 , 9 , 10 , 11 and 12 has ^' modified butt 6 ^' and a modified rear swivel 7.

The butt 6 has a cut or slot 6a along the eionga- ted cross section of its and ^" portion defining a narrow back wall βb that extends from -the tow to the heel of the same butt S .

The swivel 7 is in the form of a pivoting rod having, an enlarged outer end provided with an elongated opening. 7a through which the sling 5 is secured, and provided at its inner or pivot end with pin hole.. Forming part of the swivel 7 is its holding member 8 which, is formed, by two parallel rectangular side plates 8a having a common back, plate 3b and a bottom, plate* 8c _* The plates 3a are both provided with aligned pin holes; while the back and . bo tom plate 8b and 8c are , respectively, have two holes and two threaded holes .

The swivel 7 , through its inner or pivot and, is pivotally s ecured to the holding member 8 , through its side plates 8a, by means of a. pin 9. The holding member 3 is a s ecured inside the sloe Sa of the butt 8 , near its toe, by fastening the same by means of, screws 10 , through its back plate 8b , to the- ack wall 6b of the slot Sa _* - Fitted to the threaded hole of the bottom plate 3c , adjacent to the back plate 3b , is a fixing screw 11 , ^' and fitted to the ether threaded hole of the same bottom plate 8c is an adjustment screw 12 , It will be obser- /ed - from. Figs . 10 & 11 that the swivel

_-d has a short extended portion beyond its pin hole, so that if the tip of the fixing screw 11 is not pressing against this extended portion of the swivel rod , the swivel 7 is free to move about its pivot, S allowing the same to swing at about 90 degrees . The adjustment screw 12 is used for predetermining the

_ degrees of swing of the swivel 7; while the fixing screw 11 is designed for fixing the swivel 7 at the end of the swing. 0 Although this modified swivel 7 has also the same basic features as that of the swivel 3 , it has , however, o e good advantage particularly if applied or used on a shotgun or target rifle. .If this swivel T is fixed in the horizontal position as a rear extension of the butt 6 , the 5 swivel 7 fits- the shooter's armpit, and at the same time brings the barrel of the firearm, to eye-level to facilitate - sightings.

The third embodiment of the same invention is similar to the foregoing embodiment,, except that this 0 sling assembly, as shown in Figs . 13 , 14 , 15 , and IS , has a modified rear swivel 13.

This rear swivel 13 ^" has a T shape with elongated or slot 13a at its enlarged outer or end portion through which the sling or strap 5 is inserted. The rear swivel 5 . 13 has also at its pivot end a hole I ^' 3b and forming part of this rear swivel 13 are the required fittings consisting of a bolt or screw 14 , a sleeve 15 and may also include a washer IS and a nut 17.

If the butt o is made of plastic or nylon ail the above-mentioned fittings will be included. However,

certain distance from each other. Forming parts of the rear swivel 18 are link holder 19 , a screw 20 and a washer 21. The link holder 19 is in the form of a small place of metal block with a short cylindrical bas e and having trwo opposite shoulders , each of which is defined or. formed by horizontal surface 19a and vertical surface 19b. The link holder 19 has an axial hole 19a which extends from its top through the center of its base and a hole 19d passing transversely across its middle portion, and crossing the axial hole 19c to position each end of the hole 19d just above the horizontal surface 19a of its base..

The rear swivel 18 is adapted to be pivotally attached to the link holder 19 by a securing its two ends through the hole. 19d_ Rotatably secured to the screw- is the link holder 19 , through its axial hole 19c. It will be observed that the link 18 which can be rotated , together with the link holder 19 , at 360 degrees with respect to the screw 4 will not anyway scratch the rifle butt. It is understood that a bolt together with a nut may also be used instead of a screw , particularly if the butt 6 is made of plastic or nylon.

Although it is not clearly shown in the drawings , it is also understood that the length of the strap or sling 5 is adjustable to fit the size of the soldier or shooter:

While but four preferred embodiments of the invention with various modifications have been shown and described, it is apparent that some more modifications and changes may be made therein within spirit and scope
