Abstract
Abstract A mounting mechanism for the rear portion of a tilting cab on a motor vehicle which securely locks and supports the cab relative to the vehicle frame but which may be unlocked to permit tilting of the cab. The mounting includes a support mechanism which is released upon excessive twist of the frame to permit limited movement or separation of the cab and the frame to avoid twisting and distortion and possibly permanent damage to the cab.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
A mounting mechanism for detachable securing a tilting cab on the chassis frame of a motor vehicle comprising, a first pivot element adapted to be releasably supported in a fixed position relative to said frame for release upon tilting of said cab relative to said frame, a second pivot element adapted to be supported in a fixed position relative to said cab, a guide link pivotally connected to said first pivot element, a master link connected to said second pivot element, and a third pivot element connecting said links to each other for relative movement thereof, all of said pivot elements having pivot axes disposed parallel to each other and normally being disposed in a common plane to position said links to restrain movement of said first pivot element relative to said second pivot element, said guide link being movable in response to movement of said first and second pivot elements laterally of each other to move said third pivot element out of said plane and permit limited separation of said first and second pivot elements relative to each other when said first pivot element is in said fixed position relative to said frame.
Claim 2
Dependent Claim
194 words
A mounting mechanism for detachable securing a tilting cab on the chassis frame of a motor vehicle comprising, a first pivot element adapted to be releasably supported in a fixed position relative to said frame for release upon tilting of said cab relative to said frame, a second pivot element adapted to be supported in a fixed position relative to said cab, a guide link pivotally connected to said first pivot element, a master link connected to said second pivot element, and a third pivot element connecting said links to each other for relative movement thereof, all of said pivot elements having pivot axes disposed parallel to each other and normally being disposed in a common plane to position said links to restrain movement of said first pivot element relative to said second pivot element, said guide link being movable in response to movement of said first and second pivot elements laterally of each other to move said third pivot element out of said plane and permit limited separation of said first and second pivot elements relative to each other when said first pivot element is in said fixed position relative to said frame.
Claim 3
Dependent Claim
61 words
The combination set forth in claim 1 and further comprising an opening formed in said master link, said first pivot element passing through said opening for limited movement between a first position in which all of said pivot elements are in said plane and a second position in which said second pivot element has moved away from said first pivot element.
Claim 4
Dependent Claim
83 words
A mounting mechanism as set forth in claim 2 in which said opening formed in said master link is in the form of an elongated slot receiving said first pivot element and in which the latter is disposed at one end of said slot when said first, second and third pivot elements are disposed in said plane and in which said first pivot element is movable toward the other end of said slot when said third pivot element moves out of said plane.
Claim 5
Dependent Claim
25 words
The mounting mechanism set forth in claim 3 in which said slot is arcuate about a radius having its center at said third pivot element.
Claim 6
Dependent Claim
34 words
The mounting mechanism set forth in claim 3 and further comprising means for moving said third pivot means out of said plane in response to lateral movement of said cab relative to said frame.
Claim 7
Dependent Claim
57 words
A mounting mechanism as set forth in claim 5 in which said means for moving said third pivot means includes a tab portion associated with said second pivot element and a complementary tab portion associated with said guide link, said tab portions being engageable with each other upon said lateral movement of said cab and said frame.
Claim 8
Dependent Claim
188 words
A mounting mechanism for a tilting cab mounted on the frame of a vehicle comprising; a houSing, means detachably connecting said housing to said frame and being detachable for tilting of said cab relative to said frame, a guide link pivotally connected to said housing for movement about a first axis fixed relative to said housing, a master link connected to said guide link for pivotal movement about a second axis and being connected to said cab for pivotal movement about a third axis, said first, second and third axes normally being disposed in a common plane and in parallel relation to each other whereby said guide and master links are positioned to restrain displacement of said third axis relative to said first axis, means associated with said guide link and operative to move the latter and said second axis out of said plane upon lateral displacement of said third axis relative to said first axis upon twisting of said frame relative to said cab to permit limited vertical displacement of said first and third axes relative to each other when said housing is connected to said frame.
Claim 9
Dependent Claim
188 words
A mounting mechanism for a tilting cab mounted on the frame of a vehicle comprising; a houSing, means detachably connecting said housing to said frame and being detachable for tilting of said cab relative to said frame, a guide link pivotally connected to said housing for movement about a first axis fixed relative to said housing, a master link connected to said guide link for pivotal movement about a second axis and being connected to said cab for pivotal movement about a third axis, said first, second and third axes normally being disposed in a common plane and in parallel relation to each other whereby said guide and master links are positioned to restrain displacement of said third axis relative to said first axis, means associated with said guide link and operative to move the latter and said second axis out of said plane upon lateral displacement of said third axis relative to said first axis upon twisting of said frame relative to said cab to permit limited vertical displacement of said first and third axes relative to each other when said housing is connected to said frame.
Claim 10
Dependent Claim
47 words
The mounting mechanism set forth in claim 7 and further comprising lock means associated with said housing and being operative upon detachment of said housing from said frame to prevent movement of said master link and maintain said first, second and third axes in said common plane.
Claim 11
Dependent Claim
50 words
The mounting mechanism set forth in claim 8 in which said lock means includes a lock element disposed in spaced relationship to said master link when said housing is connected to said frame and being movable into engagement with said master link upon disengagement of said housing from said frame.
Claim 12
Dependent Claim
72 words
The mounting mechanism set forth in claim 7 in which a pin establishes said first axis and in which said master link forms a slot receiving said pin, said master link normally being positioned with said pin at one end of said slot to prevent movement of said master link in one direction and to permit movement in the opposite direction for movement of said second pivot means out of said plane.
