Total Claims: 8
Claim 1
Independent Claim
255 words
In a shower bath cabinet including a door opening having a fixed edge of predetermined contour, a shower door comprising: (a) a one-piece body including a dished closure panel having a peripheral edge portion of the same shape as the contoured edge of the door opening to be closed by said door, (b) said closure panel also having a front surface, a concave rear surface, top and bottom portions and first and second opposite side portions, (c) said edge portion comprising a substantially continuous rim, including first and second opposed side rim portions, projecting rearward from said closure panel and terminating in a free peripheral edge and (d) pivotal support means on the top and bottom portions of said body for attaching said body to the fixed edge of the door opening in operative position for pivotal movement of said body about a fixed vertical axis in the door opening (extending) spaced between said first and second side rim portions so that said body may swing between a closed position in which said body closes the door opening and said vertical axis is spaced behind said concave rear surface, and an open position in which one side portion of said body swings behind the door opening and the other side portion swings in front of the door opening, and (e) one of said side rim portions being adapted to engage the corresponding edge of the door opening when in said closed position to limit the swinging movement of said panel away from said open position.

In a shower bath cabinet including a door opening having a fixed edge of predetermined contour, a shower door comprising: (a) a one-piece body including a dished closure panel having a peripheral edge portion of the same shape as the contoured edge of the door opening to be closed by said door, (b) said closure panel also having a front surface, a concave rear surface, top and bottom portions and first and second opposite side portions, (c) said edge portion comprising a substantially continuous rim, including first and second opposed side rim portions, projecting rearward from said closure panel and terminating in a free peripheral edge and (d) pivotal support means on the top and bottom portions of said body for attaching said body to the fixed edge of the door opening in operative position for pivotal movement of said body about a fixed vertical axis in the door opening (extending) spaced between said first and second side rim portions so that said body may swing between a closed position in which said body closes the door opening and said vertical axis is spaced behind said concave rear surface, and an open position in which one side portion of said body swings behind the door opening and the other side portion swings in front of the door opening, and (e) one of said side rim portions being adapted to engage the corresponding edge of the door opening when in said closed position to limit the swinging movement of said panel away from said open position.
Claim 3
Dependent Claim
20 words
The invention according to claim 1 in which at least the major portion of the bottom rim portion declines rearward.
Claim 4
Dependent Claim
49 words
The invention according to claim 1 in which the door opening is symmetrical about a vertical center line, said vertical pivot axis coinciding with said center line so that the first and second side portions of said body are balanced about said vertical pivot axis in said operative position.
Claim 5
Dependent Claim
87 words
The invention according to claim 3 in which said pivotal support means comprises an upper hinge pin projecting upward from the top rim for registering with a corresponding hole in the upper edge of the door opening and a lower hinge pin projecting downward from the bottom rim for registering with a corresponding hole in the bottom edge of the door opening, and means for retracting one of said pins coaxially of the pivot axis to facilitate assembly and disassembly of said door in the door opening.
Claim 6
Dependent Claim
