ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a liquifier and, in particular, to one which is water-resistant, skid-resistant and drop-resistant. Still more specifically, the present invention is particularly related to a portable liquifier which can operate on replaceable batteries.
A liquifier or blender driven by rechargeable batteries provides the user with a distinct portability advantage. In particular, a cordless blender may be used anywhere, such as back yards, beaches, on boats, or at a pool side. Battery operated liquifiers that were previously marketed, however, suffered from limitations, such as the rechargeable batteries not being replaceable by the user. Such portable liquifiers also had limited water-resistance.
It is, therefore, an object of this invention to provide a portable liquifier which can operate on replaceable, rechargeable batteries and is particularly water-resistant, skid-resistant, and drop-resistant.
SUMMARY OF THE INVENTION
The foregoing object and other objects of the invention are attained in a liquifier having a base member. The base member includes a housing having an upstanding wall, a support surface at an upper end of the upstanding wall, and a substantially open bottom end. A liquifier jar is mounted on the support surface of the base member. A rigid frame member is attached to the housing member for substantially closing the open bottom end of the housing member. An elastomer cover is secured to the bottom surface of the frame member and includes a first portion in spaced relation to the bottom surface of the frame member to form a battery compartment therebetween. The cover has a pivotal door formed therewith. A hinge for the pivotal door is formed integral with the cover.
The liquifier preferably includes at least one removable battery in the battery compartment. The battery is preferably rechargeable. A portion of the battery in the battery compartment underlies a flange-like surface of the door for maintaining the door in its closed position.
The liquifier preferably includes a rocker switch pivotally mounted within an opening formed by the housing wall. A lever extends from an outer surface of the housing wall and is connected to the switch for pivoting the switch between on and off positions. A follower extends from the frame member into the path of movement of the switch, with engagement of the switch with the follower turning the switch on.
