Claim 1
Independent Claim
211 words
A friction applying assembly for a panel movable from a first position to a second position comprising: a mounting plate rigidly secured to the panel, said plate having a non-circular aperture, a hinge support arm having at one end thereof a non-circular aperture, a bolt arm having a head at one end inserted into the non-circular aperture of the hinge support arm to prevent relative movement between the bolt arm and hinge support arm, the bolt arm being elongated with a large diameter section adjacent the head and a smaller diameter section at the opposite end and a tapered conically shaped intermediate section between the large diameter section and small diameter section, a bushing having an elongated body with one end inserted into the non-circular aperture of the mounting plate and secured thereto to prevent relative movement between the bushing and mounting plate, and an internal tapered conically shaped cavity complementary to and in frictional engagement with the intermediate section of the bolt arm, a compression spring having one end seated against the bushing and the opposite end retained by fastening means on the smaller diameter section of the bolt arm, whereby the bushing is urged into movable frictional engagement with the tapered conically shaped intermediate section of the bolt arm.

A friction applying assembly for a panel movable from a first position to a second position comprising: a mounting plate rigidly secured to the panel, said plate having a non-circular aperture, a hinge support arm having at one end thereof a non-circular aperture, a bolt arm having a head at one end inserted into the non-circular aperture of the hinge support arm to prevent relative movement between the bolt arm and hinge support arm, the bolt arm being elongated with a large diameter section adjacent the head and a smaller diameter section at the opposite end and a tapered conically shaped intermediate section between the large diameter section and small diameter section, a bushing having an elongated body with one end inserted into the non-circular aperture of the mounting plate and secured thereto to prevent relative movement between the bushing and mounting plate, and an internal tapered conically shaped cavity complementary to and in frictional engagement with the intermediate section of the bolt arm, a compression spring having one end seated against the bushing and the opposite end retained by fastening means on the smaller diameter section of the bolt arm, whereby the bushing is urged into movable frictional engagement with the tapered conically shaped intermediate section of the bolt arm.
Claim 3
Dependent Claim
40 words
The friction applying assembly of claim 1 wherein the elongated body of the bushing has two sections with one having a smaller diameter than the other with a shoulder between the two sections and the spring seats against said shoulder.
Claim 4
Dependent Claim
44 words
The friction applying assembly of claim 1 wherein the mounting plate non-circular aperture has straight sides and the bushing body end inserted into the aperture has complementary mating straight sides received in the aperture to prevent relative movement between the bushing and mounting plate.
Claim 5
Dependent Claim
31 words
The friction applying assembly of claim 1 wherein the fastening means for retaining the compression spring is a pin through a bore in the smaller diameter section of the bolt arm.
Claim 6
Dependent Claim
17 words
The friction applying assembly of claim 4 wherein a washer is located between the spring and pin.
Claim 7
Dependent Claim
19 words
The friction applying assembly of claim 5 wherein there is a slip washer located between the washer and spring.
Claim 8
Dependent Claim
18 words
The friction applying assembly of claim 1 wherein the bolt arm is metal and the bushing is plastic.
