Skid steer attachment lock
View Patent ↗A skid steer attachment lock for preventing the theft of a tool attached to a skid steer loader. The device comprises of an extendable hollow shaft having a first and second opposite ends, wherein the first and second opposite ends are open and adapted to respectively accommodate a first and second attachment tool locking arms when the arms are facing each other; and a locking mechanism disposed in the outer shaft of the extendable shaft for temporarily locking the extendable shaft at a desired length.
1. An attachment lock to inhibit the illicit removal of a skid steer attachment tool from a steer skid loader, said attachment lock consisting of:
an extendable hollow shaft having an outer shaft segment and an inner shaft segment, each shaft segment having a longitudinal axis;
the outer shaft segment having a first open end along the longitudinal axis of the outer shaft segment, the first open end being configured to accommodate a first attachment tool locking arm of a steer skid loader;
the inner shaft segment having a second open end along the longitudinal axis of the inner shaft segment, the second open end being opposite the first open end and being configured to accommodate a second attachment tool locking arm of a steer skid loader, the inner shaft segment being configured to telescope into the outer shaft segment;
restriction means for preventing the inner shaft segment from telescoping through the first end, the restriction means being a hollow metal element welded to and positioned within the outer shaft segment proximate the first open end; and
a locking mechanism attached to the extendable hollow shaft for temporarily locking the extendable shaft at a desired length thereby providing the attachment lock, wherein the locking mechanism is surrounded and protected by a housing,
whereby the attachment lock is configured to prevent the illicit removal of a skid steer attachment tool from a steer skid loader.
2. An attachment lock as in claim 1 , wherein the restriction means has a generally rectangular cross-section, the outer shaft segment has a generally rectangular cross-section and is perforated to define an outer hole, and the inner shaft segment has a generally rectangular cross-section and is perforated along at least one side thereby defining a plurality of inner holes, and wherein the locking mechanism is capable of engaging with the outer hole and one of the plurality of inner holes to prevent movement of the inner shaft segment relative to the outer shaft segment.
3. An attachment lock as in claim 1 , wherein the restriction means has a generally rectangular cross-section, the outer shaft segment has a square cross-section and is perforated to define an outer hole, and the inner shaft segment has a square cross-section and is perforated along at least one side thereby defining a plurality of inner holes, and wherein the locking mechanism is capable of engaging with the outer hole and one of the plurality of inner holes to prevent movement of the inner shaft segment relative to the outer shaft segment.
4. An attachment lock as in claim 1 , wherein the outer shaft segment is configured to prevent the inner shaft segment from separating from the attachment lock when the attachment lock is held in a vertical orientation.
5. An attachment lock as in claim 1 , wherein the inner and the outer shaft segments are square in cross section.
6. An attachment lock as in claim 1 , wherein the outer and inner shaft segments and the restriction means are made of steel in order to provide durability and strength.
7. An attachment lock as in claim 1 , in combination with the first attachment tool locking arm of a steer skid loader.
8. An attachment lock to inhibit illicit removal of a skid steer attachment tool from a steer skid loader, said attachment lock consisting of:
an extendable hollow shaft having an outer shaft segment and an inner shaft segment, each shaft segment having a longitudinal axis;
the outer shaft segment, the first open end being configured to accommodate a first attachment tool locking arm of a steer skid loader;
the inner shaft segment having a second open end along the longitudinal axis of the inner shaft segment, the second open end being opposite the first open end and being configured to accommodate a second attachment tool locking arm of a steer skid loader, the inner shaft segment being configured to telescope into the outer shaft segment;
restriction means for preventing the inner shaft segment from telescoping through the first end, the restriction means being a hollow metal element of square cross-section welded to and positioned within the outer shaft segment proximate the first open end; and
a locking mechanism attached to the outer shaft segment, wherein the locking mechanism is surrounded and protected by a housing,
wherein the outer shaft segment is of square cross-section and perforated to define an outer hole, and the inner shaft segment is of square cross-section and perforated along one side thereby defining a plurality of inner holes, and wherein the locking mechanism is capable of engaging with the outer hole and one of the plurality of inner holes to prevent movement of the inner shaft segment relative to the outer shaft segment thereby temporarily locking the extendable shaft at a desired length.
9. An attachment lock as in claim 8 , wherein the outer and inner shaft segments and the restriction means are made of steel in order to provide durability and strength.
10. An attachment lock as in claim 8 , in combination with the first attachment tool locking arm of a steer skid loader.
