Abstract
Abstract A quick-release article holder adapted for mounting on a vertical surface and having a bifurcated lower support member and a spaced upper clamping member which is pivotally mounted for rotative movement into or out of engagement with the upper portion of the article to be held. The holder is particularly adapted for use in retaining cylindrical breathing apparatus which is mounted on the wall of a fire station or on a panel of a mobile fire apparatus and serves to retain and support the breathing apparatus when it is not in use or while it is being harnessed to the back of the user. A lever-operated linkage serves to pivot the upper retaining member out of clamping engagement with the apparatus so that the entire breathing apparatus can be moved horizontally away from the holder by the action of the user walking away from the holder after the breathing apparatus has been harnessed to his back. The breathing apparatus can be restored to the holder by reversing the removal procedure and moving the upper clamping member back into locking engagement with the upper part of the breathing apparatus. Adjustable features are provided for varying the spacing between the upper and lower members, changing the position of the upper member at its limits of pivotal movement and maintaining a spring-loaded clamping force on the upper member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
In a quick-release article holder for mounting on a vertical surface, the combination of a horizontally-extending lower support member adapted to underlie the article, a retaining member spaced upwardly from said support member and engageable with the article, means mounting said retaining member for pivotal movement toward and away from said article-engaging relationship, and an operation linkage connected to said retaining member for effecting said pivotal movement, said operating linkage including a link connected to said retaining member to create a moment arm about said pivotal connection, a toggle plate secured to the free end of saId link, an operating lever, a rotatable cam operatively secured to said lever and engaging said toggle plate to provide an over-center toggle joint interconnecting said link to said lever to effect linear displacement of said link relative to said moment arm in response to lever-actuated plate-displacing rotation of said cam, and spring means yieldably maintaining said toggle joint in one or the other limit of its position.
Claim 2
Dependent Claim
164 words
In a quick-release article holder for mounting on a vertical surface, the combination of a horizontally-extending lower support member adapted to underlie the article, a retaining member spaced upwardly from said support member and engageable with the article, means mounting said retaining member for pivotal movement toward and away from said article-engaging relationship, and an operation linkage connected to said retaining member for effecting said pivotal movement, said operating linkage including a link connected to said retaining member to create a moment arm about said pivotal connection, a toggle plate secured to the free end of saId link, an operating lever, a rotatable cam operatively secured to said lever and engaging said toggle plate to provide an over-center toggle joint interconnecting said link to said lever to effect linear displacement of said link relative to said moment arm in response to lever-actuated plate-displacing rotation of said cam, and spring means yieldably maintaining said toggle joint in one or the other limit of its position.
Claim 3
Dependent Claim
41 words
A combination as defined in claim 1, wherein said support member is bifurcated to provide spaced article-support arms to underlie one portion of the article, the space therebetween providing an opening for horizontal movement therethrough of another portion of the article.
Claim 4
Dependent Claim
27 words
A combination as defined in claim 1, including adjustable mounting means for said members for selectively changing the spacing between said support member and said retaining member.
Claim 5
Dependent Claim
20 words
A combination as defined in claim 1, wherein said retaining member is mounted for pivotal movement about a horizontal axis.
Claim 6
Dependent Claim
22 words
A combination as defined in claim 4, wherein said retaining member is ring-shaped and adapted to overlie an article of cylindrical shape.
Claim 7
Dependent Claim
30 words
A combination as defined in claim 1, including means carried by said link for adjustably changing the effective length thereof to vary the limits of position of said retaining member.
Claim 8
Dependent Claim
23 words
A combination as defined in claim 1, wherein said retaining member clampingly engages the article in response to lever-actuated retraction of said link.
Claim 9
Dependent Claim
36 words
A combination as defined in claim 7, including a spring-loaded lost-motion connection between said link and said retaining member to yieldably permit retraction of said link after pivotal movement of said retaining member has been arrested.
Claim 10
Dependent Claim
140 words
In a quick-release holder for an air cylinder having a downwardly-projecting necked portion, the combination of a horizontaly-extending support member adapted to underlie said cylinder, said support member having spaced support arms to permit horizontal traverse of the necked portion of said cylinder therebetween, a ring-shaped retaining member of smaller internal diameter than said cylinder spaced upwardly from said support member and adapted to be disposed in overlying clamped engagement with said cylinder, means mounting said retaining member for pivotal movement about a horizontal axis, and a lever-operated operating linkage connected to said retaining member to effect pivotal movement thereof out of and into clamping engagement with said cylinder, said linkage including a spring-loaded lost-motion connection to said retaining member to yieldably permit retraction of said linkage after pivotal movement of said retaining member has been arrested by said cyinder.
Claim 11
Dependent Claim
140 words
