Abstract
Abstract In an electromotorically driven apparatus with an apparatus component which can be driven by a drive element and which performs a reciprocating vibratory movement, strip-shaped integral hinges are provided for the parallel guidance of said apparatus component. To increase the life of the integral hinges, at least one spring which exerts a force component in the direction of the vibratory movement is provided for each of the integral hinges.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
An electromotively driven apparatus comprising an apparatus component, an electromotively driven element adapted to drive said component in a reciprocating vibratory movement, means for parallel guiding said component, said means for parallel guiding positioned at each facing side of said component in the direction of said vibratory movement and comprising at least one strip-shaped integral hinge having one end hinged to said drivable apparatus component and the other end hinged to a stationary part of said apparatus, each of said two integral hinges including at least one spring mounted with respect to said hinge for exerting a force component in the direction of said vibratory movement, said spring acting between said drivable apparatus component to be parallel guided and said stationary part of said apparatus.
Claim 2
Dependent Claim
125 words
An electromotively driven apparatus comprising an apparatus component, an electromotively driven element adapted to drive said component in a reciprocating vibratory movement, means for parallel guiding said component, said means for parallel guiding positioned at each facing side of said component in the direction of said vibratory movement and comprising at least one strip-shaped integral hinge having one end hinged to said drivable apparatus component and the other end hinged to a stationary part of said apparatus, each of said two integral hinges including at least one spring mounted with respect to said hinge for exerting a force component in the direction of said vibratory movement, said spring acting between said drivable apparatus component to be parallel guided and said stationary part of said apparatus.
Claim 3
Dependent Claim
29 words
An apparatus as claimed in claim 1, wherein said spring exerts a further force component which is directed perpendicularly to said vibratory movement and which tensions said integral hinge.
Claim 4
Dependent Claim
19 words
An apparatus as claimed in claim 1, wherein said spring extends through an opening formed in said integral hinge.
Claim 5
Dependent Claim
33 words
An apparatus as claimed in claim 3, wherein said opening takes the form of a slot which extends up to one end of said integral hinge and which is open at one end.
Claim 6
Dependent Claim
37 words
An apparatus as claimed in claim 1, wherein said drivable apparatus component to be guided in parallel, together with said integral hinges and said springs, is a structural unit adapted to be fitted onto the apparatus housing.
Claim 7
Dependent Claim
64 words
An apparatus as claimed in claim 1, wherein said drivable apparatus component to be guided in parallel comprises two parts, one of said parts being connected to said integral hinges and comprising a coupling member for the drive element, said springs associated with said integral hinges acting on the other of said parts and being adapted to be detachably connected to said coupling member.
Claim 8
Dependent Claim
46 words
An apparatus as claimed in claim 6, wherein said coupling member is connected to said integral hinges, and is adapted to be mounted in said apparatus housing, said second part together with said springs being a structural unit adapted to be fitted onto said apparatus housing.
Claim 9
Dependent Claim
11 words
The apparatus of claim 1 wherein each said spring is helical.
Claim 10
Dependent Claim
143 words
An electromotively driven housed apparatus construction comprising a reciprocatingly driven vibratory element having a plane of movement, first hinge means hingeably coupling one side of said element in said plane of movement to the housing of said apparatus, second hinge means hingeably coupling the other side of said element in said plane of movement to the housing of said apparatus, a first resilient springlike member coupled between said element and said housing for exerting a first force in said plane of movement between said housing and said element, and a second resilient springlike element for exerting a second force, opposite to said first force, in said plane of movement between said housing and said element, said resilient springlike elements taking up alternately occurring tensile and pressure loads, thereby relieving said hinges of said loads and thus substantially increasing the life of said hinges.
Claim 11
Dependent Claim
143 words
