Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
74 words
In an electrically heatable home appliance including a stationary base part and a movable top part, each of the parts being provided with a hot plate and with a hinge joint portion, a combination comprising an extendable supporting member adapted for coupling and guiding said hinge joint portions of said parts; and abutment surfaces provided on said hinge joint portions and said supporting member for holding said parts in predetermined vertical and angular positions.
Claim 2
Dependent Claim
74 words
In an electrically heatable home appliance including a stationary base part and a movable top part, each of the parts being provided with a hot plate and with a hinge joint portion, a combination comprising an extendable supporting member adapted for coupling and guiding said hinge joint portions of said parts; and abutment surfaces provided on said hinge joint portions and said supporting member for holding said parts in predetermined vertical and angular positions.
Claim 3
Dependent Claim
112 words
The combination as defined in claim 1, wherein said supporting member includes an extendable linking plate the upper end of which is pivotably coupled to the hinge joint portion connected to said top part, the lower end portion of said linking plate being provided with two pairs of laterally projecting pins, the hinge joint portion connected to said base part having two guiding grooves for guiding said projecting pins, said guiding grooves having at their upper range recesses for passing through the upper pair of said pins and being terminated with bearing cups for supporting said upper pins when said linking plate and thereby said upper part are in an elevated position.
Claim 4
Dependent Claim
42 words
The combination as defined in claim 2, wherein a first pair of abutment surfaces is provided approximately in the middle range of said guiding grooves for supporting the lower end of said linking plate when the latter is swung open about 180°.
Claim 5
Dependent Claim
44 words
The combination as defined in claim 3, wherein the top edges of said bearing cups are arranged in a slightly rearwardly inclined plane and form an abutment surface for said upper hinge joint portion when said upper part is swung open slightly above 90°.
Claim 6
Dependent Claim
31 words
The device as defined in claim 4, wherein said lower hinge joint portion extends below a bottom portion of said base part and forms rear supporting legs for said base part.
Claim 7
Dependent Claim
96 words
The combination as defined in claim 4, wherein said upper hinge joint portion has a U-shaped cross-section defining two shanks directed towards said upper part and a bridging portion, the corner area between the lower shank and said bridging portion being provided with a recess for passing through the upper end of said linking plate, said recess forming an abutment surface in said shank and another abutment surface in said bridging part, said abutment surfaces in said corner recess forming substantially a right angle and being equally spaced from the pivotable joint of said linking plate.
Claim 8
Dependent Claim
89 words
The combination as defined in claim 6, wherein an abutment nose is provided in the central area of the outer wall of said lower hinge portion for supporting the end portion of said linking plate when the latter is extended to a raised position in which the upper pair of said pins rests in said bearing cups and the upper end of said linking plate bears upon said abutment surface in said corner recess, thus holding said upper part in a spaced parallel position relative to said base part.
Claim 9
Dependent Claim
59 words
The combination as defined in claim 6, wherein said upper hinge joint portion includes an additional abutment surface arranged opposite said pivotable joint of said linking plate for supporting a surface of said linking plate when said top part is swung open slightly above 90° and rests with its side surface against the abutment surface in said corner recess.
Claim 10
Dependent Claim
33 words
The combination as defined in claim 1, wherein said upper hinge portion and said lower hinge portion are provided respectively with holding fingers for disconnectably engaging corresponding recesses provided in respective hot plates.
Claim 11
Dependent Claim
38 words
The combination as defined in claim 9, wherein the plane of the top surface of the upper hot plate in the 90° swung open position of said upper part intersects the top surface of said stationary hot plate.
Claim 12
Dependent Claim
34 words
The combination as defined in claim 1, wherein said top part is provided with a handle having an arched portion adapted for supporting said top part when the latter is swung open about 180°.
Claim 13
Dependent Claim
33 words
The combination as defined in claim 1, wherein the rear supporting legs of said base part include recesses that in cooperation with angular supporting legs form a winding track for a connection cable.
Claim 14
Dependent Claim
30 words
The combination as defined in claim 5, further including electrical connectors arranged in the empty space of the part of the lower hinge joint portion forming the rear supporting legs.
