DESCRIPTION OF THE INVENTION WITH THE HELP OF VARIOUS DRAWINGS:
The most preferred embodiment of the antiskid bowl assembly is shown in Figure 11
and in the schematic cross-sectional view of Figure 1.
The antiskid bowl assembly (1) of the instant invention mainly comprises two
components: upper one as the bowl component (as shown in figure 2) and the lower
one as the Adapter base component (as shown in figure 3). Said bowl component is
preferably made of two bowls, the inner bowl (2) and the outer plastic bowl (3), both
interlocked together at their upper edges using state-of-the art methods. Said bowl
component and the Adapter base component are so constructed that they have
provisions for mutual locking together, either of permanent nature or of non-permanent
nature. Any optional deviation from the shape, dimension and structural/constructional
12
aspects of the preferred embodiment of the antiskid bowl assembly (1), as
schematically depicted in various drawings and discussed herein, should be
considered as covered under the instant disclosure of the complete inventive concept.
Said bowl component may optionally have inner bowl (2) as a stainless steel bowl or
simply as an inner coating to the outer plastic bowl (3). Shape and dimension(s) of the
inner bowl (2) and outer plastic bowl (3) may optionally be selected as per the user’s
requirements or demand of the aesthetics or technical preferences of the person
skilled in the art.
In one preferred embodiment of the antiskid bowl assembly (1), at the bottom surface
(5) of the outer plastic bowl (3), a Ring Shaped Stand (4) is provisioned, wherein said
stand (4) is downwardly extended from said outer bottom surface (5) of the Outer
Plastic Bowl (3). At the outer cylinder surface of said ring shaped stand (4) optionally
selected locking arrangements (11), for example locking-lugs/ screw-threads, pressfit
projections etc. are provided, preferably by involving injection moulding during the
time of forming the said outer plastic bowl (3). Said structural locking arrangements
(11) are so created that each of them corresponds to another set of locking
arrangements (12), created with the Ring Lock Segment (6) of Adapter base
component. The dimension of the said Ring Shaped Stand (4) is preferably selected
as downwardly extended cylindrical wall, irrespective of the shape and dimension of
the inner bowl (2) and/or outer plastic bowl (3).
The shape/dimension of the inner bowl (2), particularly at its upper edge (13), is
optionally selected from conventional circle, oval, triangle, square, pentagon, octagon
or any other shape. Accordingly the shape and dimension of the outer plastic bowl (3)
is formed with flat bottom surface (5), so that in one hand the said inner bowl (2) is
13
effectively accommodated within the said outer plastic bowl (3) and in other side the
Ring Shaped Stand (4) is suitably formed on the outer surface of said bottom (5) of
the said outer plastic bowl (3).
In one preferred embodiment of the antiskid bowl assembly (1), the Adapter base
component, as shown in Figures 9(a) & 9(b), comprises a Ring Lock Segment (6) and
a Flexible Base Segment (or the Vacuum Rubber) (8), as shown in Figures 8(a) and
8(b). The Ring Lock Segment (6), as depicted in Figure 7, is structurally rigid and is
preferably made by plastic material in injection moulding method. The Ring Lock
Segment (6) mainly comprises a rigid flat disk (16); wherein an upwardly extended
cylindrical wall (15) is present in upper side of said flat disk (16) and a downwardly
extended cylindrical wall (17) is present below the said flat disk (16). At inner surface
of said upwardly extended cylindrical wall (15), such locking arrangements (12) (for
example locking-lugs/ screw-threads, press-fit projections etc.) are provisioned which
correspond to the locking arrangements (11) of the Ring Shaped Stand (4). Said rigid
flat disk (16) is formed either as a complete flat disk or as a flat disk with a central hole,
wherein said central hole may be created for reducing the material used.
In the preferred embodiment of the antiskid bowl assembly (1), the locking
arrangements (11) and (12) are so selected that the bowl component and the Adapter
base component are mutually locked or unlocked by the user, preferably by using his
hands and without requiring any additional tool thereof.
Said Ring Lock Segment (6) is firmly fixed/integrated with the lower flat disk (7) of the
Flexible Base Segment (8). The Flexible Base Segment (8) is preferably made of
rubber, wherein it has an outwardly extended (or concave shaped) inclined circular
wall (20), a vertical circular wall (18) and a lower flat disk (7). A suitable material other
14
than rubber may also be optionally applied for forming the Flexible Base Component
(8). The rigid flat disk (16) of the Ring Lock Segment (6) seats directly above the said
lower flat disk (7) of the Flexible Base Segment (8). Both such disks, (16) and (7), play
their role in firm mutual integration of the Ring Lock Segment (6) and the Flexible Base
Segment (8). As per the most preferred embodiment of the invention, the downwardly
extended cylindrical wall (17) of the Ring Lock Segment (6) gets accommodated within
the circular channel (19), formed between the lower flat disk (7) and the vertical circular
wall (18) thereof. At the lower region of the vertical circular wall (18), another inclined
circular wall section (20) is so positioned that the said inclined wall (20) makes an
angle larger that 900 with the said vertical circular wall (18). Principally, the concept
behind the inclined circular wall (20) of the Flexible Base Segment (8), integrated with
the Ring Lock Segment (6), is that an effective volume of cavity (10) is developed
within the inner (concave) surface of said wall (20). At the lower edge of the said
inclined circular wall (20), a handle (9) is provided for lifting the said Antiskid Bowl
Assembly (1) from the surface on which it (1) is placed.
When the said antiskid bowl assembly (1) is placed on a flat surface, preferably a
smooth surface, the circular edge of the inclined circular wall (20) of the Flexible Base
Segment (8) touches the said flat surface and accordingly the volume of the cavity
(10) gets enclosed. Mild pressing of the said Bowl assembly (1) downwardly or
applying force by any means downwardly, the inclined circular wall (20) is forced to
move downwardly, leading to reduce the enclosed volume of cavity (10) towards
creation of low pressure or vacuum inside the said Flexible Base Segment (8). Once
such low pressure or vacuum is realized within the Flexible Base Segment (8), the
antiskid feature of said Antiskid Bowl assembly (1) of the instant invention gets
activated and the said Bowl assembly (1) gets almost fixed on the smooth ground
15
surface. In normal effort of a pet while getting its feed from the said Bowl assembly (1)
is not sufficient to move it and rather such effect of the pet further presses the Flexible
Base Segment (8) towards creating a vacuum like environment within the enclosed
cavity (10).
When the antiskid bowl assembly (1), kept on a smooth surface with active antiskid
feature thereof, is lifted by holding the handle (9), firstly one region of the circular edge
of the inclined circular wall (20) leaves the surface and therefore the low
pressure/vacuum created within the cavity (10) gets released. Consequently the
antiskid feature of the said Antiskid Bowl Assembly (1) gets deactivated and it
becomes easy for the user to lift the said bowl assembly (1).
The provision of detaching the bowl component of the Antiskid Bowl Assembly (1) from
the Adapter Base Component, helps the user in many ways, namely:- (i) cleaning the
bowl components on regular basis, (ii) packing both the components separately for
easy transport, (iii) replacing any one of the two components, or (iv) using more than
one type of Bowl Components with single Adapter Base Component etc., wherein all
said Bowl Components have compatible locking arrangements with the said Adapter
Base Component being used thereof.
It will be apparent to those skilled in the art that various modifications and variations
can be made in the scheme(s), programming of various software based instructions
involved, modules provisioned for data analysis and transmission/storage involved, or
other possible arrangements and rearrangements within the present invention, without
departing from the spirit or scope of the invention. Thus, it is intended that the present
invention covers the modifications and variations of this invention provided they come
within the scope of the description, illustrations, drawings, appended claims and their
equivalents.
