TITLE OF INVENTION
A universal adapter for appliances with rotational drive motion.
APPLICANTS :
Crompton Greaves Limited, CG House, Dr Annie Besant Road, Worli, Mumbai 400 030, Maharashtra, India, an Indian Company
INVENTOR (S):
Jain Gaurav of M/S. Upkar Agencies, Varni Colony, Sagar, Madhya Pradesh - 470002, India and Kusale Sarang of Crompton Greaves Ltd, Industrial Design Centre, Global R&D Centre, Crompton Greaves Ltd., Kanjumarg (East), Mumbai - 400042, Maharastra, India ; both Indian Nationals.
PREAMBLE TO THE DESCRIPTION;
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

Field of the Invention:
This invention relates to the field of home appliances.
Particularly, this invention relates to home appliances requiring rotational drive motion.
Still particularly, this invention relates to a universal adapter for appliances with rotational drive motion.
More particularly, this invention relates to a remote rotational drive used for multiple home appliances.
Background of the Invention:
In a conventional kitchen, there exists a plurality of equipment, devices, instruments which work on rotational drive motion. Some such devices inciude a mixer / grinder, a dough kneader, a blender, a food processor, a juicer, wet waste trap, egg beater and the like. All these devices may use various vessels and various blades which rotate as driven by the rotational drive motion and at different speeds.

In today's scenario, there is a constant need to achieve compact things especially electrical equipment and devices. Also, modularity is the need of today's appliances and equipment. Instead of having multiple devices as mentioned above (which are essential devices for a standard kitchen), there is a need to have an even more compact assembly or device or system which serves as a substrate for the function for each of the above-mention devices or the like devices requiring rotational drive motion.
In a conventional kitchen a mixer occupies some space; a blender occupies some space, and the like. Some kitchens provide for such spaces which become dead spaces once they are used during the time of meal preparation. Some other kitchens do not have enough space and require that the user store it somewhere else, from where it can be retrieved during need of use.
As it is known that conventional kitchen mixer grinder is placed on a kitchen platform during operation; thus there is always a possibility of it getting it exposed to water due to the presence of kitchen sink and water supply thereof.

Prior Art:
The use of a separate motor is disclosed in GB995612 and US5112135.
However, none of these patent applications provide a modular or space saving concept wherein a single motor drives multiple appliances.
Also, a plurality of rotatable (or driven) units is not disclosed (which may be driven by a single drive unit).
Objects of the Invention:
An object of the invention is to provide a compact assembly for providing rotational drive motion remotely for multiple appliances.
Another object of the invention is to provide universal rotational drive motion.
Yet another object of the invention is to provide a modular appliance.
Still another object of the invention is to provide a modular appliance with rotational drive motion.

Summary of the Invention:
According to this invention, there is provided a universal adapter for appliances with rotational drive motion, said adapter comprises:
a. an adapter housing adapted to receive a vessel with suitable blades,
driven by rotational motion; and
b. mating means on said housing adapted to mate with a mating
mechanism with a rotational drive element powered by a motor,
said motor spaced apart from said adapter housing.
A flexible shaft and coupler is used to mate motor with adapter (housing).
Preferably, said motor is a wall mounted motor unit; electrical or pneumatic.
Typically, said rotational drive element comprises:
a. motor unit adapted to provide power; and
b. shaft adapted to translate said power into rotational motion.
Additionally, said rotational drive element comprises:
a. motor unit adapted to provide power;
b. shaft adapted to translate said power into rotational motion; and

c. gear mechanism adapted to transfer said rotational motion from said shaft onto said vessel blades.
Typically, said shaft is a flexible shaft.
Preferably, said shaft is a retractable shaft retractable into said motor unit.
Typically, said rotational drive element comprises a coupler adapted to couple said shaft to said adapter housing.
Typically, said rotational drive element comprises a coupler, said coupler being a universal coupler so that it couples the shaft to the universal adapter, through its gear mechanism in order to transfer the rotational motion from a motorized shaft to said vessel blades.
Typically, said mating means includes a complementary gear assembly with one of the gears fitted onto a motorized shaft from said motor and the other gear fitted into said universal adapted housing for translating rotational motion of said motorized shaft to blades of said vessel.
Typically, said gear assembly is connected to a static shaft adapted to connect with a coupler.

Brief Description of the Accompanying Drawings:
The invention will now be described in relation to the accompanying drawings, in which:
Figure 1 illustrates a schematic of a universal adapter for appliances with rotational drive motion along with its associated drive mechanisms.
Detailed Description of the Accompanying Drawings:
According to this invention, there is provided a universal adapter (100) for appliances with rotational drive motion.
Figure 1 illustrates a schematic of a universal adapter for appliances with rotational drive motion along with its associated drive mechanisms.
In accordance with an embodiment of this invention, there is provided an adapter housing (100) adapted to receive a vessel (V) with suitable blades. Typically, these vessels are mixer vessels, grinder vessels, blender vessels, food processing vessels which perform the tasks of mixing, grinding, blending, food processing respectively, driven by rotational motion of the blades incorporated by the vessel.

In accordance with another embodiment of this invention, there is provided a motor unit (M) adapted to provide the power it generates to drive said blades of said vessel. This motor unit is spaced apart from the universal adapter. It may be wall mounted according to a preferred embodiment. It typically occupies a minimal space on a wall.
In accordance with yet another embodiment of this invention, there is provided a shaft (S) adapted to translate power generated by the motor into rotational motion for driving the blades. The shaft is preferably a flexible shaft which may be retractable into said wall mounted motor unit. The shaft may be moved to any location with the defined length with which it is fitted to be fixed to the universal adapter. The shaft is coupled to the universal adapter.
The motor and the shaft form the rotational drive element.
In accordance with still another embodiment of this invention, there is provided a coupler (C) adapted to couple said shaft to said adapter housing. The coupler is a universal coupler so that it couples the shaft to the universal adapter, preferably through its gear mechanism in order to transfer the rotational motion.

Typically, the housing adapter includes a mating means (MT) adapted to receive the shaft (S) by means of the coupler (C). The mating means transfers the shaft motion to a rotational motion which drives the blades. The mating means may include a gear assembly (G) (with complementary gears), as shown in Figure 1 of the accompanying drawings. The gear assembly is connected to a static shaft adapted to connect with the coupler.
This invention, therefore, provides a lightweight and modular solution to the plurality of appliances which require rotational drive motion, wherein the motor is separated from each of the various appliances and replaced by a universal adapter and a plurality of vessels, preferably fitted with various blades in accordance with the need of the task that needs to be fulfilled. This also provides a space saving measure.
Also in certain exemplary cases of the present scenario, the mixer grinder has to be shifted to storage space after its use. By the incorporation of this invention, it becomes easy for the user to carry it or store it at same place due to its lightweight and compactness.
The motor unit operating flexible shaft can be mounted on any surface. Once the electrical / pneumatic connection is provided to the motor unit, the shaft at the other end starts rotating.

The operative portion of the shaft can be situated on the shaft handle as well as on the base depending on user's convenience.
