Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
A space thermostat for the sight handicapped comprising a base member adapted to be mounted on a wall of a space, temperature responsive control means mounted on said base member adapted to control temperature conditioning apparatus supplying temperature conditioned medium to a space, temperature control point adjusting means attached to said base member and connected to said temperature responsive control means for adjusting the temperature to be maintained in the space, said adjusting means having a raised control temperature reference portion, indicia support means attached to said base member and cooperating with said reference portion, raised indicia means on said indicia support means corresponding with temperature whereby a person with sight handicap can feel said reference portion and said indicia means to position said reference portion to the desired temperature control set point, said indicia support means comprises a cover ring mounted on said base member and surrounding said adjusting means, and raised indication marks on said cover ring between raised reference temperature numbers, said marks corresponding to two temperature degree steps in the movement of said adjusting means.
Claim 2
Dependent Claim
179 words
A space thermostat for the sight handicapped comprising a base member adapted to be mounted on a wall of a space, temperature responsive control means mounted on said base member adapted to control temperature conditioning apparatus supplying temperature conditioned medium to a space, temperature control point adjusting means attached to said base member and connected to said temperature responsive control means for adjusting the temperature to be maintained in the space, said adjusting means having a raised control temperature reference portion, indicia support means attached to said base member and cooperating with said reference portion, raised indicia means on said indicia support means corresponding with temperature whereby a person with sight handicap can feel said reference portion and said indicia means to position said reference portion to the desired temperature control set point, said indicia support means comprises a cover ring mounted on said base member and surrounding said adjusting means, and raised indication marks on said cover ring between raised reference temperature numbers, said marks corresponding to two temperature degree steps in the movement of said adjusting means.
Claim 3
Dependent Claim
47 words
The invention of claim 1 comprising detent means connected to said control point adjusting means to provide a tactile step movement of said adjusting means to provide an audible signal each time said adjusting means moves said raised portion between predetermined temperature marks of said indicia means.
Claim 4
Dependent Claim
150 words
A space thermostat for the sight handicapped comprising, a base member adapted to be mounted on a wall of a space, temperature responsive control means mounted on said base member, said control means adapted to control temperature conditioning apparatus for supplying temperature conditioned medium to the space, temperature control point adjusting means attached to said base member and connected to said control means for changing the control temperature thereof, said adjusting means having a raised pointer, the position of said pointer can be felt by a sight handicapped person, and a circular temperature scale mounted on said base and associated with said adjusting means and pointer, said scale comprising large raised numbers coinciding with temperature values which can be felt by a sight handicapped person so said pointer can be positioned to select the desired temperature to adjust said temperature control means to maintain the selected temperature in the space.
Claim 5
Dependent Claim
