Abstract
A structure comprising movable doors for use in tub enclosures or shower stalls, each door having a frame and a panel mounted in the frame, and adjustment apparatus for raising or lowering one side of the door to compensate for out-of-plumb wall conditions, the adjustment apparatus comprising a pair of complementary adjustment members slidably inter-engaged along edges oblique with respect to the upper edge of the doorframe, a lower adjustment member being affixed to the doorframe and an upper adjustment member having a hanger assembly integral therewith provided with rollers or glides adapted to move on a track provided on a supporting doorframe or header.
Claims10
An adjustment apparatus for movably supporting a door on a track and providing means for adjusting the ends of the door vertically to compensate for out-of-plumb wall conditions, said apparatus comprising:
- A. A lower adjustment apparatus member comprising:
- (1) means for being affixed to a door frame,
- (2) means defining an inclined bearing surface,
- (3) a tab provided at one end of said member having an aperture and having a screw disposed in said aperture, said screw being oriented substantially parallel to said inclined bearing surface,
- B. An upper adjustment apparatus member comprising:
- (1) a body portion,
- (2) means for movably engaging said track,
- (3) means provided in said body portion for threadedly engaging the threads of said screw,
- (4) chamber means for receiving the portion of said screw extending beyond said means for threadly engaging the threads of said screw, and
- (5) means defining a surface adapted to engage a surface of said lower adjustable apparatus member,
- one member of said lower and said upper adjustment apparatus members being provided with a longitudinal engaging member comprising a key having a T-shaped cross-section and the other of said members being provided with a complementary slot retaining said engaging member in slidably relationship, whereby rotation of said screw causes said upper member to slide upwardly or downwardly in relation to said lower adjustment apparatus member, thereby raising or lowering the ends of said door.
In combination:
- I. a track mounted for supporting a door, and
- II. an adjustment apparatus movably mounted on said track for supporting a door, and providing means for adjusting the ends of the door vertically to compensate for out-of-plumb wall conditions, said apparatus comprising:
- A. A lower adjustment apparatus member comprising:
- (1) means for being affixed to a door,
- (2) means defining an inclined bearing surface,
- (3) a tab provided at one end of said member having an aperture and having a screw disposed in said aperture, said screw being oriented substantially parallel with respect to said inclined bearing surface,
- B. An upper adjustment apparatus member comprising:
- (1) a body portion,
- (2) means movably engaging said track,
- (3) means provided in said body portion threadedly engaging the threads of said screw,
- (4) chamber means receiving the portion of said screw extending beyond said means for threadly engaging the threads of said screw, and
- (5) means defining a surface adapted to engage a surface of said lower adjustable apparatus member, and
- III. a door affixed to said lower adjustment apparatus member, one menber of said lower and said upper adjustment apparatus members being provided with a longitudinal engaging member comprising a key having a T-shaped cross-section and the other of said members being provided with a complementary slot retaining said engaging member in slidable relationship, whereby rotation of said screw causes said upper member to slide upwardly or downwardly in relation to said lower adjustment apparatus member, thereby raising or lowering the ends of said door.
