Input assemblies for exercise machines and methods of assembling input assemblies for exercise machines
An input assembly is for an exercise machine. The input assembly has a housing having a keypad window, an insert in the housing, and a keypad in the keypad window, the keypad being sandwiched between the housing and the insert such that a seal is formed there between, the seal being configured to prevent ingress of liquid to the housing via the keypad window.
1. An input assembly for an exercise machine, the input assembly comprising:
a housing having a keypad window;
an insert in the housing; and
a keypad in the keypad window, the keypad being sandwiched between the housing and the insert such that a seal is formed there between, said seal being configured to prevent ingress of liquid to the housing via the keypad window, wherein the housing extends from an open end to a closed end and a seam extends along opposite sides of the housing and along the closed end.
2. The input assembly according to claim 1 , wherein the housing provides a handlebar extending between the open end and the closed end and through which the keypad window is formed.
3. An input assembly for an exercise machine, the input assembly comprising:
a housing having a keypad window;
an insert in the housing; and
a keypad in the keypad window, the keypad being sandwiched between the housing and the insert such that a seal is formed there between, said seal being configured to prevent ingress of liquid to the housing via the keypad window, wherein the housing extends from an open end to a closed end and further wherein insertion of the insert into the housing compresses the keypad between the housing and the insert, thereby forming the seal.
4. The input assembly according to claim 3 , wherein the housing comprises a first housing portion and a second housing portion which are ultra-sonically welded together along a seam.
5. The input assembly according to claim 3 , wherein the housing provides a handlebar extending between the open end and the closed end and through which the keypad window is formed.
6. A method of assembling an input assembly, the method comprising:
providing a housing that extends from an open end to a closed end and has a keypad window there between;
inserting a keypad into the housing via the open end and aligning the keypad with the keypad window; and
inserting an insert into the housing via the open end thereby compressing the keypad against the housing and forming a seal there between which is configured to prevent ingress of liquid to the housing via the keypad window.
7. The method according to claim 6 , further comprising providing the housing by ultrasonically welding a first housing portion and a second housing portion together along a seam.
8. The method according to claim 6 , wherein insertion of the insert into the housing sandwiches the keypad between a compression surface of the insert and a window frame of the housing, thereby forming the seal.
9. The method according to claim 6 , wherein the insert snap engages with the housing upon insertion into the housing.
10. The method according to claim 6 , wherein the insert is rotationally locked into a predetermined orientation in the housing upon insertion into the housing.
11. The method according to claim 6 , wherein the housing provides a handlebar extending between the open end and the closed end and through which the keypad window is formed.
12. An input assembly for an exercise machine, the input assembly comprising:
a housing having a keypad window;
an insert in the housing; and
a keypad in the keypad window, the keypad being sandwiched between the housing and the insert such that a seal is formed there between, said seal being configured to prevent ingress of liquid to the housing via the keypad window;
wherein the housing extends from an open end to a closed end and comprises a window frame extending around the keypad window;
wherein the insert comprises a compression surface; and
wherein insertion of the insert into the open end sandwiches the keypad between the compression surface and the window frame, thereby forming the seal.
13. The input assembly according to claim 12 , wherein the keypad comprises a channel and the window frame comprises a lip which is received in the channel upon insertion of the insert into the housing, thereby forming the seal.
14. The input assembly according to claim 13 , wherein the lip extends around a perimeter of the window frame and the channel extends around a perimeter of the keypad.
15. The input assembly according to claim 12 , further comprising a retainer device which retains the insert in the housing.
16. The input assembly according to claim 15 , wherein the retainer device comprises a rib on the housing which snap engages with the insert upon insertion of the insert into the housing.
17. The input assembly according to claim 12 , further comprising a guiding device which guides the insert into a predetermined orientation in the housing upon insertion of the insert into the housing.
18. The input assembly according to claim 17 , wherein the guiding device comprises a protrusion on the insert which interacts with a guiding device in the housing.
19. The input assembly according to claim 12 , wherein the insert comprises an elongated body having a first body portion and a second body portion; and the compression surface is on the first body portion.
20. The input assembly according to claim 19 , further comprising a ramp surface on the first body portion, the ramp surface being configured to engage the keypad and facilitate sliding of the first body portion under the keypad upon insertion of the insert into the housing.
21. The input assembly according to claim 12 , further comprising a handlebar and a plurality of crush ribs on a second body portion, the plurality of crush ribs being configured to crush when the input assembly is coupled to the handlebar thereby frictionally engaging the input assembly with the handlebar.
22. The input assembly according to claim 12 , further comprising a handlebar; wherein the housing is fastened to an end of the handlebar by a fastener which extends through the housing and the insert.
23. The input assembly according to claim 12 , wherein the housing provides a handlebar extending between the open end and the closed end and through which the keypad window is formed.
