DETAILED DESCRIPTION
[0030] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
[0031]
[0032]
[0033] As shown in
[0034] As shown in
[0035] The valve retainer 10 also includes a projection 42, preferably threaded, extending generally perpendicularly away from the first side 28 and substantially centered on the base 26 and the boss 27. The projection 42 includes external threads 46 and a substantially annular end surface 50. The first side 28, the end surface 50, and the boss 27 may all be substantially parallel with one another. Alternatively, the boss 27 may extend in a convex shape from the first side 28 of the base 26, such that the boss 27 is thicker near the projection 42 than it is near the outer edge of the boss 27. At least a portion of the projection 42 is configured to extend through the opening 9 provided in the helmet shell 7. Preferably the entire projection 42 is disposed within the opening 9 so that the projection 42 is protected by the helmet shell 7.
[0036] A central through bore 58 of the valve retainer 10 extends through each of the threaded projection 42, the boss 27 and the base 26. The central through bore 58 is sized and configured to receive a valve body 18. The valve body 18 may be press fit or otherwise secured (e.g., by adhesives) within the central through bore 58. The base 26 of the valve retainer 10 is sealingly coupled to an exterior of a corresponding bladder 13 in the pad assembly 12 such that at least the second side 30 of the base 26 is in fluid communication with the bladder 13. The bladder 13 may be RF welded, molded, overmolded and the like to the valve retainer 10. For example, the material of the bladder 13 may be sealingly in contact with all of or a portion of the first side 28 of the base 26, and not in contact with the boss 27. When the valve retainer 10 is coupled to the pad housing 12 and the pad assembly 15 is secured to the interior of the helmet shell 7, the boss 27 engages with the inner surface 8 of the helmet shell 7 surrounding the opening 9, and the valve retainer 10 is substantially fixed with respect to the helmet shell 7.
[0037] In an alternate embodiment as shown in
[0038] The valve retainer 10a also includes a projection 42a, preferably threaded, extending generally perpendicularly away from the first side 28a and substantially centered on the base 26a. The projection 42a includes external threads 46a and a substantially annular end surface 50a. The first side 28a, the end surface 50a, and the end surfaces 38 are all substantially parallel with one another. A distance between the end surface 50a and the first side 28a is approximately two times a distance between the end surface 38 and the first side 28a. Thus, the length of the projection 42a is approximately twice the length of the standoffs 34. An extent of the projection 42a is configured to extend through the opening 9 provided in the helmet shell 7.
[0039] A central through bore 58a of the valve retainer 10a extends through each of the threaded projection 42a and the base 26a. The central through bore 58a is sized and configured to receive the valve body 18 (not shown). The valve body 18 may be press fit or otherwise secured (e.g., by adhesives) within the central through bore 58a. The second side 30a of the valve retainer 10a may be sealingly coupled to an exterior of a corresponding bladder 13 in the pad assembly 15 such that the valve body 18 is in fluid communication with the bladder 13. The valve retainer 10a can be RF welded to the exterior of the corresponding bladder 13. When the valve retainer 10a is coupled to the pad housing 12 and the pad assembly 15 is secured to the interior of the helmet shell 7, the valve retainer 10a is substantially rotationally fixed with respect to the helmet shell 7.
[0040] As shown in
[0041] As shown in
[0042] A through opening 82 is also provided in the flange portion 70 and, in the illustrated configuration, extends from a floor 86 of the manipulation recess 78 and through the flange portion 70. The through opening 82 thus communicates with the interior of the base portion 66 of the cap 14. When the cap 14 is threadedly coupled with the valve retainer 10, the through opening 82 is substantially aligned with the central opening 22 of the valve body 18. In the illustrated construction, the through opening 82 is generally cross shaped, which can accommodate slight axial misalignment of the through opening 82 with respect to the central opening 22.
[0043] With the cap 14 threadedly coupled with the valve retainer 10, the through opening 82 provides an access point for a standard inflation needle (not shown) to be inserted into the central opening 22 of the valve body 18. When the inflation needle is moved beyond the check valve or self-sealing material provided in the valve body 18, inflation fluid (e.g., air) can be introduced into or allowed to escape from the bladder 13 of the pad assembly 15 with which the valve retainer 10 is sealingly coupled.
[0044] The above described system of the valve retainer 10 and cap 14 facilitates the attachment, adjustment and removal of the pad assembly 15 without damaging or detaching the valve retainer 10 or valve body 18 from the pad assembly 15. For example, to attach the pad assembly 15 to the protective sports helmet 5, the pad assembly 15 is positioned such that the threaded projection 42 of the valve retainer 10 extends into the shell opening 9. The base portion 66 of the cap 14 is then inserted into the shell opening 9 and threadedly engaged with the threaded projection 42. In this regard, the base portion 66 is positioned radially outward of the projection 42 and the valve body 18. The cap 14 can initially be finger tightened and then, as the components begin to draw snug, a tool, such as a screwdriver, can be used to fully tighten the cap 14 and the valve retainer 10. Disassembly is the reverse operation, whereby the cap 14 is loosened and removed from the shell opening 9 and the valve retainer 10 can then be withdrawn from the internal side of the shell opening 9.

[0047] Referring further to
[0048] The top wall 138 defines a generally rectangular top opening 150. The top opening 150 is sized and configured to receive a portion of the chin strap that extends over the central body portion 118 and between the first and second chin strap openings 122, 126 of the buckle 114. The top opening 150 includes first and second laterally extending edges 152a, 152b. The bottom wall 142 defines a centrally located attachment opening 154 that is aligned with and that receives the attachment portion 130 of the buckle 114. The attachment opening 154 includes a pair of diametrically opposed first arc segment edges 158 that extend generally in the lateral direction La and that have a first diameter, and a pair of diametrically opposed second arc segment edges 162 that extend generally in the longitudinal direction Lo and that have a second diameter greater than the first diameter. Laterally extending straight edge segments 166 extend between respective ends of the first arc segment edges 158 and second arc segment edges 162. In some configurations, including configurations where the cover 110 is removably securable to the buckle 114, the larger diameter second arc segment edges 162 facilitate insertion and removal of the attachment portion 130 with respect to the attachment opening 154. In other configurations, the attachment opening 154 may be a substantially uniform circle.
[0049] The bottom wall 142 also defines a first strap opening 170 and a second strap opening 174. The first and second strap openings 170, 174 are substantially rectangular and are positioned for alignment with the first and second strap openings 122, 126 in the buckle 114 when the buckle 114 is inserted into the cover 110. As best seen in
[0050] As shown in
[0051] As viewed from above (
[0052] As viewed from the side (
[0053] As viewed from the end (
[0054] When the buckle 114 is inserted into cover 110 and the chin strap is extended through the buckle 114 and the cover 110, the chin strap and the cover 110 cooperate to substantially completely cover the body portion 118 of the buckle 114. More specifically, the outer portions of the buckle 114 are received within the channel 182, and the central area of the body portion 118, e.g., where the central rivet 134 is located, is covered by the chin strap. In this regard there is little, if any, exposed buckle surface present on the exterior of the helmet when the buckle 114 is attached to the helmet to secure the chin strap. The cover 110 may be easily removed and replaced by flexing the top wall 138 to withdraw the buckle 114 from the channel 182 and then extracting the attachment portion 130 from the attachment opening 154. The cover 110 may be formed of a rubber material that can be colored to match or compliment the color of the chin strap, the face mask, and/or the helmet, thereby increasing the aesthetic appeal of the buckle assembly.
[0055] It is to be understood that the invention is not limited to the exact details of construction, operation, exact materials or embodiments shown and described, as obvious modifications and equivalents will be apparent to one skilled in the art. For example, the valve retainer may be integrally formed with a liner portion of the pad assembly. Accordingly, the invention is therefore to be limited only by the scope of the appended claims. While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying claims.
