Abstract
Abstract A detachable hinge assembly consisting of a generally L-shaped member secured to a movable structure and a second generally z-shaped member secured to a frame, the L-shaped member having openings in each of its leg portions through which leg portions the Z-shaped members extend. The relationship between the openings and leg portions is designed so that the upward and sideward member of the L-shaped member relative to the z-shaped member is restricted, while permitting the L-shaped member to be pivoted relative to the z-shaped member, so that the movable structure to which the L-shaped member is attached can be disengaged from the z-shaped member without the use of tools.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A detachable hinge assembly comprising a first, generally L-shaped member secured to a movable structure, a second member secured to a frame, said first member defining openings in each of its leg portions, said second member having leg portions extending through the openings in said first member, the relationships between said leg portions and at least one of said openings being designed so that the upward and sideward movement of the first member relative to said second member is restricted and the first member can be pivoted relative to said second member so that the movable structure can be disengaged from said second member without the use of tools.
Claim 2
Dependent Claim
109 words
A detachable hinge assembly comprising a first, generally L-shaped member secured to a movable structure, a second member secured to a frame, said first member defining openings in each of its leg portions, said second member having leg portions extending through the openings in said first member, the relationships between said leg portions and at least one of said openings being designed so that the upward and sideward movement of the first member relative to said second member is restricted and the first member can be pivoted relative to said second member so that the movable structure can be disengaged from said second member without the use of tools.
Claim 3
Dependent Claim
34 words
A detachable hinge assembly as set forth in claim 1 in which one of said members defines a flange portion to limit the rearward movement of said first member relative to said second member.
Claim 4
Dependent Claim
40 words
A detachable hinge assembly as set forth in claim 2 in which said first member defines the flange portion adjacent the opening receiving the leg portion to limit the upward movement of the first member relative to the second member.
Claim 5
Dependent Claim
39 words
A detachable hinge assembly as set forth in claim 1 in which the second member defines a downwardly extending stop member that supports the first member and movable structure in a downwardly directed position relative to said second member.
Claim 6
Dependent Claim
136 words
A detachable hinge assembly for mounting a hood relative to the frame of a tractor comprising a first, generally L-shaped member secured to the hood, a second, generally Z-shaped member secured to the frame of the tractor, said L-shaped member defining an opening in its vertical leg portion and a second opening in its horizontally extending leg portion, said Z-shaped member comprising a first leg extending into the opening of said upwardly extending leg portion of the first member and a second leg disposed through the opening in said second leg portion of the first member, the openings in said L-shaped member and the corresponding leg portions in said Z-shaped member being defined so that the movement of the hood is restricted in the upper and sidewise directions relative to the frame member of the tractor.
Claim 7
Dependent Claim
136 words
A detachable hinge assembly for mounting a hood relative to the frame of a tractor comprising a first, generally L-shaped member secured to the hood, a second, generally Z-shaped member secured to the frame of the tractor, said L-shaped member defining an opening in its vertical leg portion and a second opening in its horizontally extending leg portion, said Z-shaped member comprising a first leg extending into the opening of said upwardly extending leg portion of the first member and a second leg disposed through the opening in said second leg portion of the first member, the openings in said L-shaped member and the corresponding leg portions in said Z-shaped member being defined so that the movement of the hood is restricted in the upper and sidewise directions relative to the frame member of the tractor.
Claim 8
Dependent Claim
50 words
A hinge assembly as set forth in claim 5 in which the vertically extending leg portion of said L-shaped member defines a flange member adapted to engage the vertical leg portion of said Z-shaped leg member to prevent movement of the hood in a rearward direction relative to said tractor.
Claim 9
Dependent Claim
53 words
A detachable hinge assembly as set forth in claim 5 in which said Z-shaped member defines a stop portion comprising a downwardly inclined leg portion whereby when the hood and associated L-shaped member is pivoted relative to said Z-shaped member it will be retained in the downwardly inclined position by said stop member.
Claim 10
Dependent Claim
82 words
A detachable hinge assembly as set forth in claim 5 in which forward movement of the hood relative to the tractor is retained by the rearward edge of the opening in the horizontal leg of the first member against the upwardly extending leg portion of the second member, this relationship of the opening in the horizontal leg of the first member to the upwardly extending leg portion of the second member also functioning as the pivotal means of the detachable hinge assembly.
