Abstract
Abstract A locking mechanism in combination with a buckle connecting the separate straps of a horse blanket. A buckle includes a T-shaped coupling and a curved U-shaped coupling which couple together to form the buckle. The strap lock itself is comprised of a flat rectangular plate which has one end folded back onto itself to form a flange member, a base and a hollow cavity at the bight of the flange. The base contains raised projections which act as stops for preventing the loss of the strap lock. The strap lock is made of a resilient material because as it is being forced into its locking position, the bight of the flange member has to spread apart enough to slide over the curved area of the U-shaped coupling. The edge of the flange member confronts the head of the T-shaped coupling and prevents the T-coupling from sliding forward and twisting and uncoupling the buckle. The base of the strap lock lies below the slot of the T-shaped coupling and also prevents this coupling from twisting, thus preventing disengagement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A strap lock for a strap buckle, said buckle having a T-shaped coupling and a curved U-shaped coupling, each having a slot for connection to separate straps attached to a horse blanket, said strap lock being insertable into one of said buckle slots for preventing uncoupling of the buckle when the blanket is in place on an animal and the T-shaped coupling and U-shaped coupling are engaged, said strap lock comprising: a flat rectangular plate having one end folded back upon itself and forming a flange, a base, and a bight between said flange and said base; when said strap lock is in a locked position said base is lying below the slot of the T-shaped coupling for preventing it from twisting, said bight is holding the engaged U-shaped and T-shaped couplings and prevents the engaged couplings from twisting and becoming uncoupled; stop means on said base for inhibiting the disengagement of said base through the slot of the U-shaped coupling;
Claim 2
Dependent Claim
161 words
A strap lock for a strap buckle, said buckle having a T-shaped coupling and a curved U-shaped coupling, each having a slot for connection to separate straps attached to a horse blanket, said strap lock being insertable into one of said buckle slots for preventing uncoupling of the buckle when the blanket is in place on an animal and the T-shaped coupling and U-shaped coupling are engaged, said strap lock comprising: a flat rectangular plate having one end folded back upon itself and forming a flange, a base, and a bight between said flange and said base; when said strap lock is in a locked position said base is lying below the slot of the T-shaped coupling for preventing it from twisting, said bight is holding the engaged U-shaped and T-shaped couplings and prevents the engaged couplings from twisting and becoming uncoupled; stop means on said base for inhibiting the disengagement of said base through the slot of the U-shaped coupling;
Claim 3
Dependent Claim
43 words
The device as recited in claim 1 wherein said strap lock is comprised of a resilient material such as plastic nylon for allowing said bight of said flange to spread apart while said base is inserted through said slot of said U-shaped coupling.
Claim 4
Dependent Claim
66 words
The device as recited in claim 1 wherein said stop means comprises at least one raised projection having a height slightly greater than the width of said slot of said U-shaped coupling, said height being close enough in dimension to said width of said slot for allowing forced insertion of said stop means through said slot and inhibiting detachment of said lock other than by force.
Claim 5
Dependent Claim
60 words
The device as recited in claim 1 wherein flange has an edge which confronts the head of said T-shaped coupling and said base lies below said slot of said T-shaped coupling, when said T-shaped coupling and said U-shaped coupling are engaged and when said strap lock is engaged, thereby preventing the disengagement of said T-shaped coupling from said U-shaped coupling.
Claim 6
Dependent Claim
49 words
The device as recited in claim 3 further comprising a slit in said raised projection for allowing forced insertion of said stop means through said U-shaped slot having a width much less than the height of said raised projection and inhibiting detachment of said lock other than by force.
