Keyboard assembly
View Patent ↗A shelf bracket is provided. The shelf bracket includes a shelf member and opposing side flanges extending from a back plate. A front flange extends from each of said opposing side flanges. The back plate, shelf member, side flange, and front flange define a cavity configured to receive an enclosure, such as by moving the enclosure in a vertical direction in and out of engagement with the cavity. The shelf member defines a bottom limit of the cavity such that movement of the enclosure into the cavity is limited to a first vertical direction and movement of the enclosure out of the cavity is limited to a second vertical direction, the second vertical direction being diametrically opposed to the first vertical direction. A support flange is optionally included, which is configured to engage with a support structure so as to provide support for the shelf bracket.
1. A keyboard assembly comprising:
a front shell portion;
a rear shell portion removably connected to said front shell portion so as to form a cavity;
a circuit board (“PCB”) positioned within said cavity, said PCB being displaced from a first end of said front shell portion;
a first end cap extending from said first end of said front shell portion towards said PCB; and
two opposing legs each engaged with said rear shell portion along their distal edges, said legs connected via a proximal edge to a back plate.
2. The keyboard assembly of claim 1 , wherein the distance between the distal edges of said opposing legs is less than the width of the back plate.
3. The keyboard assembly of claim 1 , further comprising a biasing member interacting with at least one of said two opposing legs.
4. The keyboard assembly of claim 3 , wherein said interaction occurs via one or more securing element associated with at least one of said opposing legs.
5. The keyboard assembly of claim 3 , wherein said opposing legs are configured in either an engaged or disengaged configuration depending on the positioning of said biasing member.
6. The keyboard assembly of claim 5 , wherein said opposing legs are considered to be in an engaged configuration when said biasing member interacts with both of said opposing legs.
7. The keyboard assembly of claim 1 , wherein the front shell portion defines a first longitudinal slot positioned within the cavity, wherein the first longitudinal slot is configured to selectively receive a first longitudinal edge of the PCB, thereby restraining the PCB in at least one degree of translational freedom, at least one degree of rotational freedom, and a first direction along a second degree of translational freedom.
8. The keyboard assembly of claim 1 , further comprising a keypad cover having flexible side members that snap fit around said front shell portion and said rear shell portion, with said side members operable to secure the first end cap in place.
9. The keyboard assembly of claim 1 , further comprising:
a slot extending into the cavity;
wherein the slot is configured to receive a ribbon cable extending from the PCB to a keypad selectively positioned in a first position over a generally flat and substantially solid front surface of said front shell portion;
wherein a first edge of the slot is defined by the front shell portion;
wherein a second edge of the slot is defined by the first end cap; and
wherein the first and second edges are opposed to and displaced from each other so as to accommodate receiving a thickness of the ribbon cable.
10. The keyboard assembly of claim 1 ,
wherein the front shell portion defines:
a first longitudinal slot positioned within the cavity; and
a longitudinal ledge opposed to the first longitudinal slot;
wherein the first longitudinal slot is configured to selectively receive a first longitudinal edge of the PCB when a second longitudinal edge of the PCB is rotated away from the longitudinal ledge, and
wherein the front shell portion is configured to restrain the PCB in at least two degrees of translational freedom and at least two degree of rotational freedom when the second longitudinal edge of the PCB is positioned adjacent to the longitudinal ledge of the front shell portion.
11. A keyboard assembly comprising:
a front shell portion;
a rear shell portion removably connected to said front shell portion so as to form a shell with a cavity;
a circuit board (“PCB”) positioned within said cavity, said PCB being displaced from a first end of said front shell portion;
a first end cap extending from said first end of said front shell portion towards said PCB;
a back plate having opposed first and second side edges;
a shelf member extending from said back plate; and
first and second side flanges extending from respective first and second side edges of said back plate;
wherein said shelf member and said first and second side flanges each extend in a first direction, and
wherein said back plate, said shelf member, and said first and second side flanges define a chamber, said chamber being configured to selectively receive the shell.
12. The keyboard assembly of claim 11 , further comprising first and second front flanges extending from said first and second side flanges, respectively, wherein said first and second front flanges further define said chamber.
13. The keyboard assembly of claim 11 , wherein the back plate is configured to inhibit movement of the shell in at least one direction.
14. The keyboard assembly of claim 13 , wherein each of said first and second side flanges is configured to prevent or otherwise inhibit movement of the shell in at least one direction, that direction being a different direction than a direction of inhibition of said back plate.
15. The keyboard assembly of claim 11 , wherein the shelf member extends from a bottom edge of the back plate and is configured to provide vertical support for the shell.
16. The keyboard assembly of claim 12 , wherein each of said first and second side flanges extend from a bottom portion of respective first and second side edges of said back plate.
17. The keyboard assembly of claim 11 , wherein the front shell portion defines a first longitudinal slot positioned within the cavity, wherein the first longitudinal slot is configured to selectively receive a first longitudinal edge of the PCB, thereby restraining the PCB in at least one degree of translational freedom, at least one degree of rotational freedom, and a first direction along a second degree of translational freedom.
18. The keyboard assembly of claim 11 , further comprising a keypad cover having flexible side members that snap fit around said front shell portion and said rear shell portion, with said side members operable to secure the first end cap in place.
19. The keyboard assembly of claim 11 , further comprising:
a slot extending into the cavity;
wherein the slot is configured to receive a ribbon cable extending from the PCB to a keypad selectively positioned in a first position over a generally flat and substantially solid front surface of said front shell portion;
wherein a first edge of the slot is defined by the front shell portion;
wherein a second edge of the slot is defined by the first end cap; and
wherein the first and second edges are opposed to and displaced from each other so as to accommodate receiving a thickness of the ribbon cable.
20. The keyboard assembly of claim 11 ,
wherein the front shell portion defines:
a first longitudinal slot positioned within the cavity; and
a longitudinal ledge opposed to the first longitudinal slot;
wherein the first longitudinal slot is configured to selectively receive a first longitudinal edge of the PCB when a second longitudinal edge of the PCB is rotated away from the longitudinal ledge, and
wherein the front shell portion is configured to restrain the PCB in at least two degrees of translational freedom and at least two degree of rotational freedom when the second longitudinal edge of the PCB is positioned adjacent to the longitudinal ledge of the front shell portion.
