Helmet strap clip, and assembly

Claim 2

For use with a helmet chin strap and forward and rearward straps connected to and depending from the helmet, a clip structure, comprising (a) a first upright clip element having forward slot means connectible with the forward strap, and rearward slot means connectible with the rearward strap, (b) a second upright clip element having lower slot means connectible with the chin strap, (c) the two elements having upper and lower pairs of interconnectible tongue and groove means whereby they are connectible together and disconnectible from one another in response to finger pressure exertion thereon.

Claim 3

The combination of claim 1 wherein the two clip elements have opposed faces brought into predetermined face-to-face registration in response to interconnection of the tongue and groove means.

Claim 4

The combination of claim 1 wherein the two-clip elements when interconnected form a Y-shaped assembly with two upper diverging portions and a lower stem portion, the forward and rearward slot means located at said upper diverging portions, and said lower slot means located at said lower stem portion, the upper pair of tongue and groove means located between said two upper diverging portions defined by the first clip element.

Claim 5

The combination of claim 3 wherein the second clip element defines said lower stem portion, and also has an upper stem portion which partly overlies said two upper diverging portions which are defined by the first clip element.

Claim 6

For use with a helmet chin strap and forward and rearward straps connected to and depending from the helmet, a clip structure, comprising (a) a first upright clip element having forward slot means connectible with the forward strap, and rearward slot means connectible with the rearward strap, (b) a second upright clip element having lower slot means connectible with the chin strap, (c) the two elements having interconnectible tongue and groove means whereby they are connectible together and disconnectible from one another in response to finger pressure exertion thereon, (d) the two clip elements when interconnected forming a Y-shaped assembly with two upper diverging portions and a lower stem portion, the forward and rearward slot means located at said upper diverging portions, and said lower slot means located at said lower stem portion, (e) said interconnectible tongue and groove means including (i) upper tongue and groove parts located generally between said forward and rearward slot means, (ii) lower tongue and groove parts located above said lower slot means.

Claim 7

For use with a helmet chin strap and forward and rearward straps connected to and depending from the helmet, a clip structure, comprising (a) a first upright clip element having forward slot means connectible with the forward strap, and rearward slot means connectible with the rearward strap, (b) a second upright clip element having lower slot means connectible with the chin strap, (c) the two elements having interconnectible tongue and groove means whereby they are connectible together and disconnectible from one another in response to finger pressure exertion thereon, (d) the two clip elements when interconnected forming a Y-shaped assembly with two upper diverging portions and a lower stem portion, the forward and rearward slot means located at said upper diverging portions, and said lower slot means located at said lower stem portion, (e) said interconnectible tongue and groove means including (i) upper tongue and groove parts located generally between said forward and rearward slot means, (ii) lower tongue and groove parts located above said lower slot means.

Claim 8

The combination of claim 5 wherein said upper tongue and groove parts interfit generally vertically in response to downward motion of the second clip element relative to the first clip element, the upper tongue part projecting generally vertically.

Claim 9

The combination of claim 6 wherein said lower tongue and groove elements interfit in response to motion of the second clip element bringing said face-to-face elements into predetermined registration, said lower tongue part projecting generally normal to said faces.

Claim 10

The combination of claim 7 wherein said two elements have V-shaped surfaces which are interengageable to act as guides in response to said bringing of the elements into predetermined registration.

Claim 11

The combination of claim 6 wherein said two elements have V-shaped surfaces which are interengageable to act as guides in response to said bringing of the elements into predetermined registration, said V-shaped surfaces located proximate said upper tongue and groove parts.

Claim 12

The combination of claim 1 including said helmet chin strap connected to said lower slot means.

Claim 13

The combination of claim 10 including said helmet forward and rearward straps connected to said forward and rearward slot means, respectively.

Claim 14

The combination of claim 7 wherein said lower tongue and groove means form a detent connection.

Claim 15

The combination of claim 11 including the helmet connected with said chin strap and with said forward and rearward straps.

Claim 16

The combination of claim 1 wherein said clip elements consist of molded plastic material.

Claim 17

The combination of claim 12 wherein the lower tongue has (i) an upper convex nose surface to cam against a first lower surface defined by the first element, thereby to cause the lower tongue to enter the lower groove, and (ii) a lower convex nose surface to cam against a ramp defined by the first element, thereby to cause spring deflection of the lower tongue, which is cantilevered, and retention of the lower nose surface adjacent a crest defined by the ramp, when the two elements are in face-to-face interengagement.
