Abstract
In a security system, a transmitter housing and first and second transmitter actuation elements cooperate to define thumb and finger saddles on opposite sides of the housing. The peripheral edge of the housing and the first and second actuation elements have matched configurations aligned at the thumb and finger saddles for guiding a hand to properly operate the transmitter while blocking other objects from accidental operation. The housing extends beyond the actuation elements at the ends of the elements while the actuation elements extend beyond the housing at the center of the elements. The housing has a first texture, such as a rigid plastic, while the actuation elements have a softer feel provided, for example, by an elastomeric material.
Claims15
A hand portable communicator for use with a security system, said communicator comprising:
- a radio frequency transmitter;
- a housing containing said transmitter, said housing having a peripheral edge defining first and second opposed concavities, said concavities extending inwardly at opposite sections of said peripheral edge;
- and,
- actuation keys supported for relative movement in said housing, said keys including first and second opposed actuation surfaces accessible from outside said housing for operating said transmitter, said first and second surfaces being inwardly concave adjacent said first and second housing concavities, respectively.
A hand holdable communicator including a wireless transmitter, a housing containing the transmitter and defining a peripheral edge, and first and second actuation elements for operating the transmitter, characterized in that:
- the housing defines first and second pairs of arcuate lips at said peripheral edge on opposite sides of said housing, respectively, said lip pairs being concave inwardly relative to said housing,;
- and,
- the first and second actuation elements define opposed arcuate surfaces concave inwardly relative to said housing and accessible between said lips to operate the transmitter, said arcuate surfaces lying closely adjacent said respective lip pairs.
A hand holdable communicator including a wireless transmitter, a housing containing the transmitter and defining a peripheral edge, and first and second actuation elements for operating the transmitter, characterized in that:
- said peripheral edge of said housing and said first and second actuation elements together define thumb and finger saddles on opposite sides of said housing, respectively, said peripheral edge and said first and second actuation elements having aligned depressions at said thumb and finger saddles.
A hand portable communicator for use with a security system, said communicator comprising:
- a radio frequency transmitter;
- a housing containing said transmitter, said housing having first and second spaced panels joined along a peripheral edge extending between said panels, said peripheral edge defining opposed concave sections including opposed apertures in said peripheral edge;
- and,
- two actuation keys for operating said transmitter, said keys having opposed actuation surfaces accessible through said opposed apertures and defining concave shapes conforming approximately to the shape of said concave sections.
