Abstract

Embodiments of the invention provide thermostat controls having improved tactile feedback. According to one embodiment, a thermostat includes a bottom member, a switch, a top member, and a motion guiding member or assembly that operationally couples the top member with the bottom member so that the top member is inwardly pressable by a user relative to the bottom member to allow the thermostat to receive input from the user by contacting the switch with a component of the top member or the bottom member. The motion guiding member or assembly contacts the top member near its outer periphery to control the inward motion of the top member relative to the bottom member to provide the improved tactile feedback.

Claims

1. A device for controlling an energy consuming system comprising:

a bottom member;

a switch;

a top member; and

a motion guiding member that operationally couples the top member with the bottom member such that the top member is inwardly pressable and pivotable relative to the bottom member to allow the device to receive input from a user by contacting the switch with a component of the top member or the bottom member;

wherein the switch is positioned near a central axis of the top member and the motion guiding member comprises a plurality of stop members that engage with corresponding components of the bottom member near an outer periphery of the bottom member to enable the top member to pivot relative to the bottom member, wherein pivoting of the top member involves three contact points including (1) a pivot point defined by engagement of a first stop member and a first component of the bottom member, (2) an inwardly directed force applied to the top member by the user generally opposite the pivot point, and (3) a mechanical engagement of the switch and the component of the top member or the bottom member, said switch being leverably forced inward responsive to the pivoting of the top member.

2. The device of claim 1, wherein the switch is centrally disposed on the bottom member and wherein the component comprises a rod coupled with the top member, the rod being positioned over the switch such that inward pressing of the top member causes the rod to contact the switch.

3. The device of claim 1, further comprising a spring coupled with the plurality of stop members, the spring biasing the top and bottom members apart.

4. The device of claim 3, further comprising a plurality of posts, each post being slidably disposed through an aperture of the bottom member and coupled with the top member such that rotational movement of the top member relative to the bottom member is limited.

5. The device of claim 1, further comprising a ring-shaped component rotationally coupled with the top member, the ring-shaped component being configured to track a rotational input motion to allow the user to scroll between options of a menu system.

6. The device of claim 5, wherein contacting the switch with the component of the top member or the bottom member allows the user to select an option of the menu system.

7. A device for controlling an energy consuming system comprising:

a bottom member;

a switch;

a top member; and

a motion guiding member that operationally couples the top member with the bottom member such that the top member is inwardly pressable and pivotable relative to the bottom member to allow the device to receive input from a user by contacting the switch with a component of the top member or the bottom member;

wherein the switch is positioned near a central axis of the top member and the motion guiding member comprises a plurality of stop members that engage with flanges of the top member near an outer periphery of the top bottom member to enable the top member to pivot relative to the bottom member, wherein pivoting of the top member involves three contact points including (1) a pivot point defined by engagement of a first stop member and a first flange of the top member, (2) an inwardly directed force applied to the top member by the user generally opposite the pivot point, and (3) a mechanical engagement of the switch and the component of the top member or the bottom member.

8. The device of claim 7, wherein the switch is centrally disposed on the bottom member and wherein the component comprises a rod coupled with the top member, the rod being positioned over the switch such that inward pressing of the top member causes the rod to contact the switch.

9. The device of claim 7, further comprising a spring disposed between the top member and the bottom member, the spring biasing the top and bottom members apart.

10. The device of claim 9, further comprising a plurality of posts, each post being slidably disposed through an aperture of the bottom member and coupled with the top member such that rotational movement of the top member relative to the bottom member is limited.

11. The device of claim 7, further comprising a ring-shaped component rotationally coupled with the top member, the ring-shaped component being configured to track a rotational input motion to allow the user to scroll between options of a menu system.

12. The device of claim 11, wherein contacting the switch with the component of the top member or the bottom member allows the user to select an option of the menu system.
