Hinge set

Claim 2

A gravity hinge for swingably mounting a door member on a frame member, comprising a first hinge part adapted to be secured to one of said members and having a pintle receiving opening and an inclined cam surface at least partially surrounding said opening, a second hinge part adapted to be secured to the other of said members and having a pintle and a cam follower for riding on said cam surface, a detent in said cam surface for receiving said cam follower to restrain said door in an open position, and adjustable means selectively positionable over said detent to prevent said cam follower from entering said detent.

Claim 3

A gravity hinge as set forth in claim 1 wherein said adjustable means is a member removably positioned in said detent.

Claim 4

A gravity hinge as set forth in claim 1 wherein said first hinge part comprises a bracket member having a first portion adapted to lie against said frame member and a second plate-like portion lying in a horizontal plane, a load bearing member provided with said cam surface and disposed on said plate-like portion, said plate-like portion having a slot therein and said load bearing member therein having a slot therein, said slots extending in mutually transverse directions, a sleevelike portion of said load bearing member depending into said slot in said plate-like portion and a fastening element extending through a hole in said plate-like portion into the other of said slots for securing said load bearing member to said bracket, whereby said load bearing member is adjustable in two substantially transverse directions relative to said frame member.

Claim 5

A gravity hinge set comprising the hinge set forth in claim 3 and a second hinge, said second hinge comprising a bracket adapted to be secured to said frame member and having a plate-like portion with a slot therein, a bearing member having a pintle receiving opening aligned with said slot, and means pivotally mounting said bearing member on said bracket for adjusting the position of said pintle receiving opening relative to said frame member.

Claim 6

A gravity hinge as set forth in claim 1 wherein said second hinge part is an integral unit comprising a mounting flange portion, said rod-like pintle portion extending from said flange portion, and said cam follower extending partially along one side of said pintle portion.

Claim 7

A gravity hinge set comprising the hinge set forth in claim 1 and a second hingE, said second hinge comprising a bracket adapted to be secured to said frame member and having a plate-like portion with a slot therein, a bearing member having a pintle receiving sleeve disposed in said slot, and means pivotally mounting said bearing member in said bracket for adjusting the position of said bearing member relative to said frame member.

Claim 8

A gravity hinge set comprising first and second hinges respectively including a first hinge part adapted to be secured to a door and a second hinge part adapted to be secured to a frame member, said hinge parts each including an L-shaped bracket and a bearing member adjustably secured to a respective one of said brackets, one of said bearing members being adjustable on the respective bracket in a first direction in a horizontal plane and the other of said bearing members being adjustable in two transverse directions in a horizontal plane on the other bracket.

Claim 9

A gravity hinge set comprising first and second hinges respectively including a first hinge part adapted to be secured to a door and a second hinge part adapted to be secured to a frame member, said hinge parts each including an L-shaped bracket and a bearing member adjustably secured to a respective one of said brackets, one of said bearing members being adjustable on the respective bracket in a first direction in a horizontal plane and the other of said bearing members being adjustable in two transverse directions in a horizontal plane on the other bracket.

Claim 10

A gravity hinge set according to claim 7 wherein said second hinge comprises a hinge as set forth in claim 1.

Claim 11

A gravity hinge comprising an L-shaped bracket adapted to be secured to a door frame member, a load bearing member adjustably mounted on said bracket and having a pintle receiving opening at least partially surrounded by an inclined cam surface, said cam surface having a pair of oppositely disposed aligned grooves and a pair of slots intersecting said grooves, and a pair of members respectively insertable in said slots and having inclined upper surface portions overlying said grooves when said members are disposed in said slots.

Claim 12

A gravity hinge comprising an L-shaped bracket adapted to be secured to a door frame member, a load bearing member adjustably mounted on said bracket and having a pintle receiving opening at least partially surrounded by an inclined cam surface, said cam surface having a pair of oppositely disposed aligned grooves and a pair of slots intersecting said grooves, and a pair of members respectively insertable in said slots and having inclined upper surface portions overlying said grooves when said members are disposed in said slots.

Claim 13

A gravity hinge as set forth in claim 9 wherein the axis of said grooves intersects the principal axis of said pintle receiving opening.
