Abstract
A mixing device (2) provided with a motor (12) received in a work portion (3) for driving a mixer rod (7) is adapted to be assembled without the need for screw-threaded connections and adhesives. For this purpose, the individual components (12, 19, 24, 4, 60, 70) are so relatively arranged and equipped with noses and projections for interengagement or latching that, after all components are fitted together, a completely assembled mixing device (2) is obtained which is totally enclosed in its outer circumferential contour.
Claims17
A hand-held household appliance, such as an immersion mixer, comprising a work portion having first and second engaging portions, bearing structure including a latch portion for engagement with said first engaging portion of said work, a motor received in said work portion, said motor being supported in said bearing structure when said bearing structure latch portion is in engagement with said first engaging portion of said work portion, and a handle portion including an engagement portion for engagement with said second engaging portion of said work portion for rigid securing of said handle portion to said work portion, said handle portion accommodating control components of said motor such that said work portion, said bearing structure, said control components, and said handle portion can be assembled in a particular successive sequence after which they are securely interconnected, and can then be disassembled only in reverse order of said particular successive sequence.
A hand-held household appliance, in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said bearing structure having two arm portions and said handle portion having a flange and a nose, said bearing structure and said handle portion being fixedly secured to said work portion by having one of said arm portions of said bearing structure engage into an opening of said work portion and another of said arm portions engaging said flange formed on said handle portion and said nose of said handle portion engaging into an opening in said work portion, and said handle portion being engaged with said bearing structure by an axial guideway disposed opposite said flange and said another arm portion.
A hand-held household appliance, in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said motor having its driven end axially slidably received in said work portion via a resilient bearing, and its other end supported on said bearing structure and secured in said work portion by engaging means on said bearing structure and by engaging means on said handle portion.
A hand-held household appliance, in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said work portion having an opening and being adapted to be completed to a device housing by said handle portion, said handle portion including for insertion into said work portion a slotted guide provided on the peripheral rim of said opening, said guide being adapted to be pushed on the front edges of said opening of said work portion such that a nearly closed circumferential surface is obtained between the device housing and said handle portion.
A hand-held household appliance in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said bearing structure including a dovetail and said handle portion including a dovetail guide extending approximately parallel to the longitudinal axis of the device and adapted to be slid on said dovetail on said bearing structure.
A device as claimed in claimed 11, characterized in that the cord is run to the outside through a bore provided on the side of the handle portion.
A hand-held household appliance, in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said handle portion having opening structure and cord receiving structure at its end remote from said motor which serves to receive and fasten the motor-side end of a power cord, and a cover having hook extensions on its underside is adapted to be into said opening structure, with said hook extensions being adapted to be introduced between said bearing structure and said cord receiving structure until said hook extensions are in locking engagement with the underside of said cord receiving structure and at the same time said hook extensions on the cover are laterally guided through wall parts of said bearing structure and said cord receiving structure.
A hand-held household appliance, in particular an immersion mixer, comprising a work portion, bearing structure, a motor received in said work portion adapted to be supported in said bearing structure and serving to drive a tool, a handle portion adapted to be rigidly secured to said work portion, and control components of said motor,
- said bearing structure, said work portion and said handle portion each being provided with engaging means which, as individual parts are assembled in successive sequence, are each adapted to be securely interconnected with said work portion or with a part assembled in a prior or subsequent operation,
- said work portion including opening structure opposite said handle portion, and a rocker control disposed in said opening structure, said rocker control being pivoted to said bearing structure by means of pivot pin structure, and a nose on the end of said rocker control opposite said pivot pin structure said nose limiting the rotational movement of said rocker control in outward direction.
A device as claimed in claimed 15, wherein said rocker control further includes spring structure that bears against a wall part of said bearing structure and resiliently urges said rocker control in said outward direction.
