Abstract
Abstract A latching means for use upon the hood of a vehicle. The latch has a ball and socket interlock with definitive camming surfaces and the elements are so interrelated that the latching action includes an over center movement. The over center movement of the latch allows for greater latch security with far less operator effort. In most installations, the operating force required to operate this latch is horizontal, away from the body, as opposed to a vertical force at arms length that is required on latches without this over center feature.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A latch for drawing and securing two elements together using the over center principal comprising; substantially socket shaped latch receiving means comprising a pair of spatially located arcuate ears adapted to be secured to one of the elements, extendable linking means pivotally attached to the other of the elements, and handle means pivotally attached to the linking member and having a first and adapted to be hand engaging and a second substantially ball shaped end including camming surfaces integral therewith for cooperation with the latch-receiving means whereby the ball can be engaged with the socket and the handle member pivoted about the ball latching the two elements together.
Claim 2
Dependent Claim
108 words
A latch for drawing and securing two elements together using the over center principal comprising; substantially socket shaped latch receiving means comprising a pair of spatially located arcuate ears adapted to be secured to one of the elements, extendable linking means pivotally attached to the other of the elements, and handle means pivotally attached to the linking member and having a first and adapted to be hand engaging and a second substantially ball shaped end including camming surfaces integral therewith for cooperation with the latch-receiving means whereby the ball can be engaged with the socket and the handle member pivoted about the ball latching the two elements together.
Claim 3
Dependent Claim
46 words
A latch as in claim 1 wherein the linking means is substantially Y-shaped and adapted to be attached to the element to be latched at the foot of the Y and the handle means is attached to and positioned between the two arms of the Y.
Claim 4
Dependent Claim
39 words
A latch as in claim 2 wherein the latch is so designed that when in the latched position the socket of the latch-receiving means and the ball portion of the handle means lie between the arms of the Y.
Claim 5
Dependent Claim
15 words
A latch as in claim 1 wherein the linking means is a one-piece elastomeric element.
Claim 6
Dependent Claim
24 words
A latch as in claim 1 wherein the handle means, when latched, is biased against the surface of the element supporting the latch-receiving means.
Claim 7
Dependent Claim
22 words
A latch as in claim 1 wherein the ball-shaped end portion has camming surfaces integral therewith for cooperation with the latch-receiving means.
Claim 8
Dependent Claim

Claim 9
Dependent Claim
19 words
A latch as in claim 6 wherein the camming surfaces are radially outwardly extending and have an irregular shape.
Claim 10
Dependent Claim
106 words
A latch for drawing and securing two elements together using the over center principal comprising; substantially socket-shaped latch-receiving means adapted to be secured to one of the elements, extendable one-piece elastomeric linking means pivotally attached to the other of the elements, and handle means pivotally attached to the linking member and having a first end adapted to be hand engaging and a second ball-shaped end having radially outwardly protruding camming surfaces having an irregular profile adapted to be engaged by the edges of the socket whereby the ball can be engaged with the socket and handle member pivoted about the ball latching the two elements together.
Claim 11
Dependent Claim
106 words
A latch for drawing and securing two elements together using the over center principal comprising; substantially socket-shaped latch-receiving means adapted to be secured to one of the elements, extendable one-piece elastomeric linking means pivotally attached to the other of the elements, and handle means pivotally attached to the linking member and having a first end adapted to be hand engaging and a second ball-shaped end having radially outwardly protruding camming surfaces having an irregular profile adapted to be engaged by the edges of the socket whereby the ball can be engaged with the socket and handle member pivoted about the ball latching the two elements together.
