Abstract
Abstract A key ring clip lock apparatus for holding the plunger of a gas pump handle in a positional mode for automatic pumping operation has a key holding portion for directly holding keys or the like thereon, including a resiliently deformable portion for permitting opening and closing of the key holding portion to receive and to remove such keys or the like, and a clip-like portion for grabbing part of the pump handle to hold the apparatus thereto with the plunger in a substantially compressed, valve-open position so as to allow hands-off gas pumping operation of an associated gas pump. In a preferred embodiment the apparatus is a formed rigid metal wire with first and second rigid lengths, one being concave curved with respect to the other, and a connecting length securing them in relatively fixed positions spaced apart a distance adequate to accommodate at least part of the plunger and pump handle with the plunger in an automatic pumping positional mode, and the key holding portion is formed of a rebent extension of the second rigid length providing a useful lever arm to facilitate placing and removing keys and to provide an enlarged effective surface to facilitate manual manipulation and use of the apparatus.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
105 words
A key ring clip lock apparatus for pump handles and their plungers, or the like, comprising holding means for directly holding keys or the like, said holding means including a resiliently deformable portion for permitting opening of said holding means to receive and to remove keys or the like; and clip means cooperative with said holding means for holding the apparatus to a gas pump handle and for confining between said holding means and said clip means at least a portion each of the pump handle and of the plunger thereof in an automatic pumping positional mode normally to retain the plunger in such mode.
Claim 2
Dependent Claim
105 words
A key ring clip lock apparatus for pump handles and their plungers, or the like, comprising holding means for directly holding keys or the like, said holding means including a resiliently deformable portion for permitting opening of said holding means to receive and to remove keys or the like; and clip means cooperative with said holding means for holding the apparatus to a gas pump handle and for confining between said holding means and said clip means at least a portion each of the pump handle and of the plunger thereof in an automatic pumping positional mode normally to retain the plunger in such mode.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1, wherein said apparatus comprises a formed metal wire of sufficient thickness to give the apparatus adequate strength and rigidity for holding the plunger in the automatic pumping positional mode, said wire having a diameter sufficiently small for placing keys thereon.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 or 2, said holding means comprising parallel arms joined at one end thereof.
Claim 5
Dependent Claim
92 words
The apparatus of claim 3, the other end of a first one of said arms having an upturned portion facing a second one of said arms, a clearance space between an edge of said upturned portion of relatively small dimension to avoid release of keys therebetween, and said one arm forming a lever arm to facilitate application of force to deform said holding means at the junction of the ends of said arms thereby to enlarge said clearance space to permit passage of keys therethrough for direct mounting on said holding means.
Claim 6
Dependent Claim
17 words
The apparatus of claim 4, further comprising curved means for integrally joining said first and second arms.
Claim 7
Dependent Claim
43 words
The apparatus of claim 1, further comprising connecting means for connecting said holding means and said clip means, said holding means including a substantially linear arm and said connecting means comprising a further linear arm generally perpendicular with respect to the former arm.
Claim 8
Dependent Claim
33 words
The apparatus of claim 1 or 2, said clip means comprising a curved arm openingg concavely toward said holding means for engaging the pump handle with the concave side of said curved arm.
Claim 9
Dependent Claim
34 words
The apparatus of claim 7, said curved arm having an approximate radius of curvature with a center of such curvature being positioned approximately on an axis that is approximately perpendicular to said holding means.
Claim 10
Dependent Claim
78 words
The apparatus of claim 8, said holding means comprising a pair of generally parallel arms generally coplanar with said clip means, one of said parallel arms forming a rebent extension of the other and said parallel arms being joined by a curved length at one end thereof, and said center of curvature being approximately on an axis that extends perpendicularly from about one-fourth to about three-fourths of the length of one of said arms of said holding means.
Claim 11
Dependent Claim
109 words
The apparatus of claim 9, further comprising rigid connecting means generally coplanar with said arms and clip means for securing said clip means and said holding means in fixed relative positions spaced apart from each other with the linear dimension between opposite ends of said curved arm of said clip means being approximately the same, parallel, and coextensive with respect to that of one of said parallel arms of said holding means, one of which parallel arms is closer to said curved arm than is the other of said parallel arms, and which closer parallel axis is for engaging and retaining the plunger in its automatic pumping positional mode.
Claim 12
Independent Claim
110 words
An apparatus for holding the plunger of a gas pump handle in an automatic pumping positional mode, comprising a formed rigid metal wire having first and second rigid lengths and a connecting link generally coplanar with and securing said first and second lengths in relatively fixed positions spaced apart a distance adequate to confine between them at least a part each of the plunger and pump handle with the plunger in an automatic pumping positional mode, the apparatus having adequate strength and rigidity to hold the plunger in such positional mode and being cooperative with the resilient reaction force of the plunger to hold the apparatus on the pump handle.
