Publication number: 20230331197Abstract: A pump head configured to secure various air valve types is disclosed. The pump head may include a housing defining an aperture sized and shaped to receive a valve head therein; a moveable pin disposed within the housing defining a pin notch disposed about an exterior circumference of the moveable pin; a first taper unit disposed in the housing; a second taper unit disposed in the housing and adjacent to the first taper unit, the second taper unit biased away the first taper unit; and an elastic ring disposed between the first and second taper units, wherein the second taper unit is moveable towards the first taper unit, thereby compressing the elastic ring circumferentially in at least one of two positions, the elastic ring compressed about the pin notch in the first position and about the valve head in the second position.Type: ApplicationFiled: June 19, 2023Publication date: October 19, 2023Inventors: Stephen C.

Patent number: 11679743Abstract: A pump head configured to secure various air valve types is disclosed. The pump head may include a housing and an interior unit sized and shaped to receive a valve head. A moveable pin disposed within the housing coaxially with the first axis may define a pin notch disposed about an exterior circumference of the moveable pin. A first taper unit may be disposed in the housing coaxially with the first axis and coupled to the pin return spring. A second taper unit may be disposed in the housing coaxially with the first axis and adjacent to the first taper unit. An elastic taper C-ring may be disposed between the first and second taper units. The second taper unit is moveable towards the first taper unit, thereby compressing the elastic taper C-ring circumferentially in at least one of two positions, the elastic taper C-ring compressed about the pin notch in the first position and about the valve head in the second position.Type: GrantFiled: December 22, 2021Date of Patent: June 20, 2023Assignee: Bell Sports, Inc.Inventors: Stephen C.

Patent number: 9376841Abstract: A lock comprising a shackle and a shackle-receiving portion. The shackle can comprise a resilient flexible portion, which, absent any external deformation forces, can retain an overall substantially U-shaped form. The shackle-receiving portion can comprise a locking mechanism operable to secure the shackle to the shackle-receiving portion. The substantially U-shaped form can comprise substantially straight and parallel legs. The flexible portion can further comprise a heat-treated coil spring that maintains the overall substantially U-shaped form, and the shackle can further comprise a cable.Type: GrantFiled: September 3, 2014Date of Patent: June 28, 2016Assignee: Bell Sports, Inc.Inventor: Andy Yu Sang Chan
