Abstract

Abstract A computer system unit including a tower unit having a generally narrow base with respect to the depth and height of the tower unit. An extensible leg capable of extending in a generally transverse direction to the depth of the tower unit may be extended on only one side of the tower unit to prevent the tower unit from overturning. Means are provided for attaching the extensible leg to the base of the tower unit.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 73 words
A computer system unit comprising: a tower unit having a generally narrow width base with respect to the depth and height of said tower unit; two slidably extensible legs, each of said legs capable of extending to only one side of said tower unit for preventing said tower unit from overturning, said extensible legs slidably engaging and cooperatively interacting with each other; and means for attaching said extensible legs to said tower unit.
Claim 2
Dependent Claim 73 words
A computer system unit comprising: a tower unit having a generally narrow width base with respect to the depth and height of said tower unit; two slidably extensible legs, each of said legs capable of extending to only one side of said tower unit for preventing said tower unit from overturning, said extensible legs slidably engaging and cooperatively interacting with each other; and means for attaching said extensible legs to said tower unit.
Claim 3
Dependent Claim 50 words
The computer system unit of claim 1, wherein each of said extensible legs retracts substantially within the area of said base of said tower unit to permit said tower unit to be placed substantially adjacent to a wall or side of a desk on which side said leg is retracted.
Claim 4
Dependent Claim 24 words
The computer system unit of claim 1, further comprising: a retracting locking means for locking each of said legs in the fully extensible position.
Claim 5
Dependent Claim 25 words
The computer system unit of claim 1, further comprising: an extending resisting means for resisting each of said legs from extending from the retracted position.
Claim 6
Dependent Claim 36 words
The computer system unit of claim 1, further comprising: at least one guide member for guiding said extensible legs while extending and retracting said legs, said guide member attaching to said base of said tower unit.
Claim 7
Dependent Claim 69 words
The computer system unit of claim 1, wherein said means for attaching said extensible legs to said tower unit comprises: a base member having a generally planar lower surface with opposing first and second side walls generally perpendicular to said planar lower surface, said opposing first and second side walls attaching to said base of said tower unit in a direction transverse to the depth of said tower unit.
Claim 8
Dependent Claim 48 words
The computer system unit of claim 6, further comprising: a plurality of stops attached to said base member and a corresponding plurality of vertical tabs attached to said extensible legs, said vertical tabs contacting with said stops for preventing said extensible legs from dislocating with said tower unit.
Claim 9
Dependent Claim 16 words
The computer system unit of claim 1, wherein said extensible legs are identical to each other.
Claim 10
Dependent Claim 26 words
The computer system unit of claim 1, wherein each of said extensible legs has a length greater than one-half of the width of said tower unit.
Claim 11
Dependent Claim 236 words
A stabilizing apparatus for a computer system tower unit, wherein the tower unit has a generally narrow base with respect to the depth and height of the tower unit, comprising: a base member having a generally planar lower surface with opposing first and second side walls generally perpendicular to said plane lower surface, said opposing first and second side walls attaching to the base of the tower unit in a direction transverse to the depth of the tower unit; two slidably extensible legs received between the base of the tower unit and said generally planar lower surface of said base member, each of said legs capable of extending to only one side of the tower unit for preventing said tower unit from overturning, each of said legs has a length greater than one-half of the width of the tower unit, wherein said legs slidably engage and cooperatively interact with each other and wherein each of said legs retracts substantially within the area of the base of the tower unit; a plurality of stops attached to said base member and a corresponding plurality of vertical tabs attached to said extensible legs, said vertical tabs contacting with said stops for preventing said extensible legs from dislocating with the tower unit; and at least one guide member for guiding said extensible legs while extending and retracting said legs, said guide member attaching to the base of the tower unit.
Claim 12
Dependent Claim 236 words
A stabilizing apparatus for a computer system tower unit, wherein the tower unit has a generally narrow base with respect to the depth and height of the tower unit, comprising: a base member having a generally planar lower surface with opposing first and second side walls generally perpendicular to said plane lower surface, said opposing first and second side walls attaching to the base of the tower unit in a direction transverse to the depth of the tower unit; two slidably extensible legs received between the base of the tower unit and said generally planar lower surface of said base member, each of said legs capable of extending to only one side of the tower unit for preventing said tower unit from overturning, each of said legs has a length greater than one-half of the width of the tower unit, wherein said legs slidably engage and cooperatively interact with each other and wherein each of said legs retracts substantially within the area of the base of the tower unit; a plurality of stops attached to said base member and a corresponding plurality of vertical tabs attached to said extensible legs, said vertical tabs contacting with said stops for preventing said extensible legs from dislocating with the tower unit; and at least one guide member for guiding said extensible legs while extending and retracting said legs, said guide member attaching to the base of the tower unit.
Claim 13
Dependent Claim 15 words
The stabilizing apparatus of claim 10, wherein said extensible legs are identical to each other.
