Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
Electrical apparatus comprising: (a) a stand, an appliance supportable by the stand, and an electrical connector device located between said stand and said appliance; (b) electrical socket means in said connector device; (c) electrical plug means on said appliance and releasably engaged in said socket means; (d) first detent means to mechanically couple said stand to said electrical connector device, second detent means to mechanically couple said connector device to said appliance; (e) a bistable mechanism operative to actuate said first and second detent means; and (f) manually actuable means at a location separate from said electrical connector device operative to switch the bistable mechanism between a first state in which the first detent means couples said stand to said device and the second detent means does no coupling, and a second state in which the second detent means couples said device to said appliance and the first detent means does no coupling.
Claim 2
Dependent Claim
153 words
Electrical apparatus comprising: (a) a stand, an appliance supportable by the stand, and an electrical connector device located between said stand and said appliance; (b) electrical socket means in said connector device; (c) electrical plug means on said appliance and releasably engaged in said socket means; (d) first detent means to mechanically couple said stand to said electrical connector device, second detent means to mechanically couple said connector device to said appliance; (e) a bistable mechanism operative to actuate said first and second detent means; and (f) manually actuable means at a location separate from said electrical connector device operative to switch the bistable mechanism between a first state in which the first detent means couples said stand to said device and the second detent means does no coupling, and a second state in which the second detent means couples said device to said appliance and the first detent means does no coupling.
Claim 3
Dependent Claim
47 words
An electrical apparatus as claimed in claim 1, wherein the electrical connector device comprises a first male portion and a second male portion, said first male portion includes switch means being operable by insertion of said plug means into said socket means to energize said socket means.
Claim 4
Dependent Claim
44 words
An electrical connector device as claimed in claim 2 wherein side walls of said first male portion are apertured for passage of said second detent means; and wherein side walls of said second male portion are apertured for passage of said first detent means.
Claim 5
Dependent Claim
31 words
An electrical connector device as claimed in claim 2 wherein said bistable mechanism is housed in said second male portion and is mechanically connected to said first and second detent means.
Claim 6
Dependent Claim
28 words
Electrical apparatus as claimed in claim 1 wherein the bistable mechanism is housed in said connector device; and wherein the manually actuable means is housed in said stand.
Claim 7
Dependent Claim
16 words
Electrical apparatus as claimed in claim 1 wherein said bistable mechanism is housed in said stand.
Claim 8
Dependent Claim
16 words
Electrical apparatus as claimed in claim 1 wherein said bistable mechanism is housed in said appliance
Claim 9
Dependent Claim
42 words
Electrical apparatus as claimed in claim 1 wherein said manually actuable means comprises actuators mounted on said mechanism, and said mechanism carries one of said detent means and controls the other of said detent means via said one of the detent means.
Claim 10
Dependent Claim
211 words
Electrical apparatus comprising: (a) a stand, an appliance supportable by the stand, and an electrical connector device located between the stand and said appliance; (b) electrical socket means in said connector device; (c) electrical plug means on said appliance and releasably engaged in said socket means; (d) first detent means movable between an operative position mechanically coupling said stand to said electrical connector device and an inoperative position in which it does no coupling; (e) second detent means movable between an operative position mechanically coupling said connector device to said appliance and an inoperative position in which it does no coupling; (f) a bistable mechanism operatively associated with said first and second detent means and switchable reversibly between a first stable condition actuating the first detent means to its operative position and actuating the second detent means to its inoperative position, and a second stable condition actuating the first detent means to its inoperative position and actuating the second detent means to its operative position; and (g) manually actuable means disposed solely on one of said stand, appliance and connector device, and actuable by a single manual displacement to switch the bistable mechanism between said first and second stable conditions to effect simultaneous actuation of said first and second detent means.
Claim 11
Dependent Claim
211 words
Electrical apparatus comprising: (a) a stand, an appliance supportable by the stand, and an electrical connector device located between the stand and said appliance; (b) electrical socket means in said connector device; (c) electrical plug means on said appliance and releasably engaged in said socket means; (d) first detent means movable between an operative position mechanically coupling said stand to said electrical connector device and an inoperative position in which it does no coupling; (e) second detent means movable between an operative position mechanically coupling said connector device to said appliance and an inoperative position in which it does no coupling; (f) a bistable mechanism operatively associated with said first and second detent means and switchable reversibly between a first stable condition actuating the first detent means to its operative position and actuating the second detent means to its inoperative position, and a second stable condition actuating the first detent means to its inoperative position and actuating the second detent means to its operative position; and (g) manually actuable means disposed solely on one of said stand, appliance and connector device, and actuable by a single manual displacement to switch the bistable mechanism between said first and second stable conditions to effect simultaneous actuation of said first and second detent means.
Claim 12
Dependent Claim
18 words
An electrical apparatus as in claim 9, wherein the appliance carries the manually actuable means and said mechanism.
Claim 13
Dependent Claim
48 words
Electrical apparatus as claimed in claim 9 wherein said mechanism comprises two bolt members each of which carries at least one of said detent, and is slidably mounted for reciprocal movement relative to the other bolt member and is linked to the other bolt member by a cross-link.
