Description
IrOG'1C FOR BOIrT-AL'1'IOI~ FIRBARX
SPECIFICATION
FIBLD Op T8S INP~tTIOZI
The present invention relates to a gun lock. More particularly this invention concerns an insert lock for a bolt-action firearm.
B~CxGROD~iD OF THB Il~lVE~iTION
Nowadays it is becoming standard practice and even the law in many jurisdictions to require that any firearms be made l0 unusable or inaccessible. The gun cabinet is expensive and prevents a person fro~a displaying the firearms.
Various gun locks have been provided that inhibit trigger action of firearms. They are fairly effective but often somewhat easy to overcome as both faces of the lock are exposed on opposite sides of the trigger guard. They can be relatively easily drilled out or pried loose. In addition they do not prevent the firearja from actually being stolen.
Some more secure syste~as are described in US patents 3,673,725 of Cravener, 4,262,127 of Karkkainen, 5,081,779 of 2o Pack, and 5,361,525 of Bowes. All these systems have the lock, including a key-operated cylinder, actually integrated into the pistol or rifle. Operation of the key can disable a necessary part of the firing mechanism, for instance preventing the trigger from being pulled back. They cannot reasonably be retrofitted to existing firearms and also do not prevent the gun from being stolen.
OB.TBCTS OF TH$ INPS~tTION
It is therefore an object of the present invention to provide an improved gun Lock, in particular for a bolt-action firearm.
to Another ob3ect is the provision of such an improved gun lock, in particular for a bolt-action firearm which overcomes the above-given disadvantages, that is which is very difficult to overcome and easy to use.
A further object is the provision of such a gun lock that can actually inhibit unauthorized moving of the weapon.
B~RY OF Tg8 I~iVENTIOl~1 A firearm has a rearvardly open longitudinally eartend-ing breech formed with a transversely inwardly open recess and with a bolt normally fitting in and closing the breech but 2o removable wholly therefrom and having a stop engageable in the recess to retain the bolt in the breech. A lock for this firearm has according to the invention an elongated metal insert fittable snugly in the breech and extending past the recess and a retain-ing element displaceable transversely on the insert between a locking position projecting from the insert and, when the insert is fitted to the breech, engaging in the recess and a freeing position recessed in the insert and permitting the insert to be fitted longitudinally into and removed longitudinally from the breech. A key-operated cylinder on the insert coupled to the retaining element can displace same between its positions.
Thus this system replaces the bolt with an insert which can only be removed from the gun's breech by means of a key, and that renders the weapon completely inoperative while it is i_n place. The system can readily be adapted to fit a multiplicity of different weapons, even antique ones. once it is removed from the rifle and the bolt is reinstalled, the weapon handles nor-orally.
The insert according to the invention is formed with a groove and the lock further has according to the invention a flexible element having one end adapted to be anchored and an opposite end complementarily engageable in the groove and not removable therefrom so that the firearm is tethered by the flexible element. Thus the lock actually can prevent theft of the weapon without requiring it to be locked away. This insert can be formed with a pair of such grooves and the flexible element can be provided on its opposite end with a clip having feet engageable in the grooves. These grooves are diametrally opposite each other relative to a longitudinal axis of the insert and the clip is U-shaped.
In accordance with the invention the cylinder has a core rotatable about a longitudinal axis of the insert and provided with an extension having an entrainment formation offset from_the axis and coupled to the retaining element. In addition a spring urges the retaining element into the locking position.
Furthermore the insert and the breech have interengaging forma-tions preventing rotation of the insert in the breech when the IO insert is fully inserted into the breech.

B~RY OF Tg8 I~iVENTIOl~1 A firearm has a rearvardly open longitudinally eartend-ing breech formed with a transversely inwardly open recess and with a bolt normally fitting in and closing the breech but 2o removable wholly therefrom and having a stop engageable in the recess to retain the bolt in the breech. A lock for this firearm has according to the invention an elongated metal insert fittable snugly in the breech and extending past the recess and a retain-ing element displaceable transversely on the insert between a locking position projecting from the insert and, when the insert is fitted to the breech, engaging in the recess and a freeing position recessed in the insert and permitting the insert to be fitted longitudinally into and removed longitudinally from the breech. A key-operated cylinder on the insert coupled to the retaining element can displace same between its positions.
Thus this system replaces the bolt with an insert which can only be removed from the gun's breech by means of a key, and that renders the weapon completely inoperative while it is i_n place. The system can readily be adapted to fit a multiplicity of different weapons, even antique ones. once it is removed from the rifle and the bolt is reinstalled, the weapon handles nor-orally.
The insert according to the invention is formed with a groove and the lock further has according to the invention a flexible element having one end adapted to be anchored and an opposite end complementarily engageable in the groove and not removable therefrom so that the firearm is tethered by the flexible element. Thus the lock actually can prevent theft of the weapon without requiring it to be locked away. This insert can be formed with a pair of such grooves and the flexible element can be provided on its opposite end with a clip having feet engageable in the grooves. These grooves are diametrally opposite each other relative to a longitudinal axis of the insert and the clip is U-shaped.
In accordance with the invention the cylinder has a core rotatable about a longitudinal axis of the insert and provided with an extension having an entrainment formation offset from_the axis and coupled to the retaining element. In addition a spring urges the retaining element into the locking position.
Furthermore the insert and the breech have interengaging forma-tions preventing rotation of the insert in the breech when the IO insert is fully inserted into the breech.
BZtIBP D88C.btIPTIO~ OF THE DR~~1G
The above and other objects, features, and advantages Will become more readily apparent from the following descriptian, reference being made to the accompanying drawing in which:
FIG. 1 is a side view of a bolt-action carbine with a lock according to the invention:
FIG. 2A is a partly diagrammatic section through the lock of this invention:
FIGS. 2B and 2C are views like FIG. 2A through alterna-tive arrangements in accordance with the invention;
FIG. 3 is a side view of the bolt of the rifle of FIG. 1; and FIG. 4 is a side view mainly in axial section through the breeGx lock according to the invention.
SPECIFIC DEBCRIPTIOld As seen in FIGS. 1 and 3 a carbine 1 has a bolt 2 that can engage in a breach 4 at the rear end of a barrel 3. A catch element or dog 20 on the side of the bolt 2 can engage in a recess 8 formed as a radially inwardly open groove in the breech 4 to retain the bolt 2 in the breech 4. As is standard, this bolt 2 can press a cartridge into the rear end of the barrel 3 and a firing pin normally in the bolt 2 can be operated to fire the cartridge, whereupon the bolt 2 can be retracted to eject the l0 spent casing and restart the loading/firing cycle. A stop normally prevents the bolt 2 from being withdrawn rearwardly as illustrated from the breech 4 altogether, but the stop can be depressed or pivoted out of the way to allow such withdrawal, as is necessary for instance to clean the gun.
. According to the invention a basically cylindrical insert body 5 is inserted from the rear along a longitudinal axis A of the barrel 3 into the breech 4 once the bolt 2 has been removed. This insert, 5 is basically cylindrical and of the same shape and diameter as the bolt 2 so it fills the breech 4 and, fits snugly into the rear end of the barrel 3.
As shown in FIG. 4 the insert 5 is provided With a key cylinder t having a core 11 that can be rotated about the axis A
by a key 9 bitted to displace schematically illustrated tumblers 10. An extension 12 of the core 11 has an eccentric crank nose 13 that engages in a retaining dog or slide 7 displaceable in a laterally open recess 21 formed in the insert 5. A spring 22 urges the dog 7 outward and this dog 7 has an angled face 23 allowing it be rammed into the recess 21 when the insert 5 is pushed into the rear end of the breech 4. When the insert 5 is fitted to the breech 4 this dog 7 fits in the recess 8 and retains it axially in place. Due to the tight fit of the insert 5 in the breech 4, it is impossible to slip a tool in and depress the dog 7; instead it must be pulled in by the key 9 in order to pull the insert 5 out of the rear end of the breech 4.
1o The insert 5 is provided With an upwardly extending screw 14 that fits in the normally provided doWnwardly open groove at the rear end of the barrel 2, so that once in position the insert 5 cannot be rotated about the axis A. In addition the sides of the insert are each formed with a pair of longitudinally extending and radially outwardly open grooves that are diametral-ly opposite each other relative to the axis A and that are rearwardly closed and forwardly open. A flexible antitheft element 17, for instance a chain, has one end secured to a fixed point 18 and an opposite end provided with a horseshoe-shaped clip 16 whose feet are fitted into the grooves IS, held in place thin by a dovetail or undercut shape of these grooves 15 and the fit of the feet against the sides of the breech 4. This clip 16 can be slid on the insert 5 as it is moved forward through the laterally open breech, but once the front end of the insert 5 is in the rear end of the barrel 2, it is captured. As a result only a person irith a key can remove the insert and untether the rifle 1.
FIG. 2B shows another system where instead of a pair of diametrally opposite and radially outwardly open grooves 15 there is a single dovetail groove 24 in which is fitted a dovetail-section retainer 16a connected via a cable or chain 17 to another such retainer 16a'. This system allows two firearms to be tied together, with the element 17 running through a fixed eye or the like, to secure them both. In FIG. 2C a fixed stanchion 19 is secured to the clip 16a so that the gun can actually be hung up by the lock.

. According to the invention a basically cylindrical insert body 5 is inserted from the rear along a longitudinal axis A of the barrel 3 into the breech 4 once the bolt 2 has been removed. This insert, 5 is basically cylindrical and of the same shape and diameter as the bolt 2 so it fills the breech 4 and, fits snugly into the rear end of the barrel 3.
As shown in FIG. 4 the insert 5 is provided With a key cylinder t having a core 11 that can be rotated about the axis A
by a key 9 bitted to displace schematically illustrated tumblers 10. An extension 12 of the core 11 has an eccentric crank nose 13 that engages in a retaining dog or slide 7 displaceable in a laterally open recess 21 formed in the insert 5. A spring 22 urges the dog 7 outward and this dog 7 has an angled face 23 allowing it be rammed into the recess 21 when the insert 5 is pushed into the rear end of the breech 4. When the insert 5 is fitted to the breech 4 this dog 7 fits in the recess 8 and retains it axially in place. Due to the tight fit of the insert 5 in the breech 4, it is impossible to slip a tool in and depress the dog 7; instead it must be pulled in by the key 9 in order to pull the insert 5 out of the rear end of the breech 4.
1o The insert 5 is provided With an upwardly extending screw 14 that fits in the normally provided doWnwardly open groove at the rear end of the barrel 2, so that once in position the insert 5 cannot be rotated about the axis A. In addition the sides of the insert are each formed with a pair of longitudinally extending and radially outwardly open grooves that are diametral-ly opposite each other relative to the axis A and that are rearwardly closed and forwardly open. A flexible antitheft element 17, for instance a chain, has one end secured to a fixed point 18 and an opposite end provided with a horseshoe-shaped clip 16 whose feet are fitted into the grooves IS, held in place thin by a dovetail or undercut shape of these grooves 15 and the fit of the feet against the sides of the breech 4. This clip 16 can be slid on the insert 5 as it is moved forward through the laterally open breech, but once the front end of the insert 5 is in the rear end of the barrel 2, it is captured. As a result only a person irith a key can remove the insert and untether the rifle 1.
FIG. 2B shows another system where instead of a pair of diametrally opposite and radially outwardly open grooves 15 there is a single dovetail groove 24 in which is fitted a dovetail-section retainer 16a connected via a cable or chain 17 to another such retainer 16a'. This system allows two firearms to be tied together, with the element 17 running through a fixed eye or the like, to secure them both. In FIG. 2C a fixed stanchion 19 is secured to the clip 16a so that the gun can actually be hung up by the lock.
