Description
Technical Field
This invention relates to swivels and more particularly to a quick-point reversible sling swivel for rifles, shotguns and the like.
Background of the Invention
Conventional slings for rifles have their rear 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 parades or long hikes.
In target practice, when the shooter is in a prone, sitting or kneeling position, the sling is used to make a not-so-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. In case of emergency, such as during ambuscades, it takes a long time and deliberate movement to untangle the sling from the shoulder and put the rifle at firing position. Precious seconds are lost and the delay may cost a life.
European soldiers have made some improvement by attaching the swivels at the side of their submachineguns so that they can fire the same from waist or hip level during emergencies with the sling still attached at their shoulders. But firing the firearms from the hips or waist level requires a lot of practice and consumption of a considerable quantity of ammunition. Some users of submachineguns have developed the tendency to "walk" the bullets towards the targets, and hitting the target beyond ten meters from the waist or hip level becomes guesswork.
The present sling assembly, as embodied in this invention, allows a rifle, shotgun or submachinegun to be carried in a ready position at a waist or hip level parallel to the ground, in a well balanced position without tiring the arms of the soldier. At this ready position, the firearm can be fired instantly from the waist or hip and, more importantly, can be mounted at the shoulder and fixed at eye level for accurate firing or shooting.
Summary of the Invention
An object, therefore, of this invention is to provide a sling assembly for a rifle, shotgun or similar firearm that considerably increases the usefulness of the firearm.
Another object of this invention is to provide a sling assembly for a rifle, shotgun or similar firearm which allows said firearm, when carried while sitting or in a standing position, to have its sling secured across the shoulder of the soldier or hunter and to have the grip held comfortably by one hand.
Another object 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 a ready-to-fire and well balanced position by securing its sling across the shoulder of the soldier or hunter with the firearm parallel to the ground, which allows the firearm to be carried at hip or waist level at the left or right side for left handed or right handed shooters by merely reversing the position of the sling, and which allows the user to hold the firearm grip with only one hand, or with both hands free, or with the firearm vertical to the ground, while its weight is borne through the shoulder, thus preventing undue strain on the arm.
Still another object of this invention is to provide a sling assembly for a rifle, shotgun or similar firearm which allows said firearm to be fired instantly from the waist or hip level, if necessary, but more importantly moved instantly upward and mounted at the shoulder and fired at eye level with considerable accuracy. The sling assembly automatically guides the butt to the correct point at the shoulder.
A further object of this invention is to provide a sling assembly for a rifle, shotgun or similar firearm which allows a soldier or hunter while sitting down or relaxing, or even while sleeping, to have the sling across his shoulder but ensures that he can immediately put said firearm in a ready-to-fire position in case of emergency.
A further object of this invention is to provide a sling assembly for a rifle, shotgun or similar firearm whose sling portion aids the shooter in steadying his firearm not only in conventional or target positon, but also in firing on full automatic in actual combat.
Other objects and advantages of this invention will become clear and apparent as this specification proceeds.

Description of a Preferred Embodiment
Referring to FIGS. 1 to 6 a sling swivel assembly according to this invention includes a rear portion of the butt 1 of a firearm stock, a fore-end 2 of the same firearm, 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 and a sling or strap 5 of considerable length whose ends are connected to the rear swivel 3 and the front swivel 4.
The rear swivel 3 has a T-shape with an elongated slot 6 at its enlarged outer end portion through which the sling or strap 5 is inserted. As a result of bending the slot 6 upward and rearward, a protrusion or tongue 7 protrudes at the outer end of the swivel 3. This tongue 7 prevents the sling 5 from scraping the surface of the butt 1.
The rear swivel 3 has also at its pivotal end a hole 8 and forming part of this rear swivel assembly are the required fittings consisting of a bolt 9 or screw, a sleeve and washer combination 10, a lockwasher 11 to prevent the bolt 9 from loosening, and a round nut 12. The diameter of this round nut 12 is slightly wider than the pivotal end of the swivel 3, and has a tail-like appendage which we shall call a retainer 13 which slightly penetrates the butt 1, thus preventing the round nut 12 from loosening from the bolt 9. More importantly, the retainer 13 prevents the swivel 3 from rotating a complete 360 degrees, thus preventing the twisting of the sling 5. In wooden butts, a wood screw can be used instead of a bolt 9 and the lock-washer removed.
The fore-end swivel 14 is also T-shaped with an elongated slot 14 at its enlarged outer end portion through which the sling 5 is inserted. It also has a tongue 15. The fore-end swivel 4 has a longitudinal hole 16 running along its narrow and pivotal end. This elongated hole 16 allows the swivel 4 to extend or retract to make it self-adjusting. At the end of this narrow and pivotal end is another tail-like appendage called a retainer 17 which also prevents the swivel 4 from rotating completely thus preventing the sling 5 from twisting. Forming part of this fore-end swivel is a bolt 18 with an enlarged mid-portion, a sleeve 19 and a nut 20.
