Abstract

Abstract A snap operating vane of this invention constituting an automatic blinker particularly adapted to the control of automobile signals is characterized by a plurality of parallel bosses being aligned at predetermined positions and having the center lines forming a certain angle with the longitudinal axis of an electric heating belt, said electric heating belt being secured to the vane through slots in substantial extended elements of said vane where the longitudinal axis of said slot and extended elements are coincidental with the axis of said belts.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 77 words
A snap operating device characterized in that said device comprises a vane made of resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent and held in a stressdeformed state by the contracted state of said tractive member, said vane includes elements projecting substantially therefrom and being diagonally opposed, and said projected elements include hooking grooves for receiving said expansible tractive member''s ends.
Claim 2
Dependent Claim 77 words
A snap operating device characterized in that said device comprises a vane made of resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent and held in a stressdeformed state by the contracted state of said tractive member, said vane includes elements projecting substantially therefrom and being diagonally opposed, and said projected elements include hooking grooves for receiving said expansible tractive member''s ends.
Claim 3
Dependent Claim 109 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state, said vane includes projected parts extending substantially from both ends of said vane by 20 to 30 percent of said vane''s diagonal, and hooking grooves are provided at the innersides of said projected parts, and slots are provided at the outsides of said projected parts to regulate bending of said project parts relative to said vane.
Claim 4
Dependent Claim 109 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state, said vane includes projected parts extending substantially from both ends of said vane by 20 to 30 percent of said vane''s diagonal, and hooking grooves are provided at the innersides of said projected parts, and slots are provided at the outsides of said projected parts to regulate bending of said project parts relative to said vane.
Claim 5
Dependent Claim 159 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state around the line forming a certain angle against itself and further in a tensed state, and projected parts are provided at both ends of said vane extending substantially from said vane, and hooking grooves are provided in said projected part, said vane includes a plurality of substantially parallel bosses whose parallel axis form an acute angle with the longitudinal axis of said expansible tractive member, said bosses being arranged in two sets symmetric to the center of said vane, and being arranged so that a line tangential to the inner ends of a set of bosses is perpendicular to the longitudinal axis of said tractive member.
Claim 6
Dependent Claim 159 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state around the line forming a certain angle against itself and further in a tensed state, and projected parts are provided at both ends of said vane extending substantially from said vane, and hooking grooves are provided in said projected part, said vane includes a plurality of substantially parallel bosses whose parallel axis form an acute angle with the longitudinal axis of said expansible tractive member, said bosses being arranged in two sets symmetric to the center of said vane, and being arranged so that a line tangential to the inner ends of a set of bosses is perpendicular to the longitudinal axis of said tractive member.
Claim 7
Dependent Claim 120 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state, said vane includes a plurality of bosses each of whose longitudinal axis being substantially parallel and forming a certain angle with the longitudinal axis of said tractive member, said bosses being arranged in two sets symmetric to the center of said vane, and being arranged so that lines connecting inner ends of the bosses of a set are perpendicular to the longitudinal axis of said tractive member.
Claim 8
Dependent Claim 120 words
A snap operating device characterized in that said device comprises a vane made of a resilient material having generally a single plane and an expansible tractive member secured to said vane at its both ends, said vane being bent in a contracted state of said tractive member and maintained in a stress-deformed state, said vane includes a plurality of bosses each of whose longitudinal axis being substantially parallel and forming a certain angle with the longitudinal axis of said tractive member, said bosses being arranged in two sets symmetric to the center of said vane, and being arranged so that lines connecting inner ends of the bosses of a set are perpendicular to the longitudinal axis of said tractive member.
