FOLDABLE MAT
Abstract
A foldable mat adapted to be carried by a child and used thereby
at nursery school, kindergarten and elsewhere as a type of bed or
pad for rest periods. The mat includes a soft, pliable core
enclosed in a colorful casing stitched to the core along
longitudinally extending and also along transversely extending
lines, at least certain of which form hinges that facilitate a
child's folding of the mat into a compact package for storage and
carrying. A cover secured to the mat in generally overlying
relation with the upper face of the cover serves as a blanket, and
a protective sheet removably secured to the underside of the mat
protects the same from dirt and abrasion during use. Pockets
provided by the mat adjacent one end thereof permit a smock, cap
and other articles to be conveniently and accessibly carried, and
the folded mat can be placed within a napsack equipped with straps
to permit the same to be carried as a backpack by a small
child.

Description
This invention relates to mats and, more particularly, to foldable
mats such as those used by children during rest periods in nursery
school, kindergarten and elsewhere.
It is common for school children in the lower grades, nursery
school and kindergarten for example, to have rest periods during
which they recline on the floor preferably upon a small pad
provided for this use -- very small area-rugs often being employed
for this purpose. Arrangements of this type are less than
satisfactory since rugs and similar products used therefor do not
afford a child any degree of comfort, they are difficult to fold
and carry, they are often heavy, and they have substantially no
esthetic attraction for children.
An object of the present invention is to provide a product
specifically intended as a rest mat for children to be used thereby
at home, at school and elsewhere as, for example, while travelling
in a station wagon or like vehicle. Another object of the invention
is in the provision of a mat adapted for uses of the types
described, and in which the mat lies flat along a floor surface or
the like for use to afford a relatively large area and is foldable
into a small compact package for storage and transport.
Further objects, among others, of the present invention are that of
providing an improved foldable mat of the character described that
is colorful and attractive; is generally utilitarian and
comfortable in use; that is equipped with a cover that serves as a
blanket to overlie a child resting upon the mat; which also has a
protective sheet of durable, easily cleaned material along the
underside thereof to protect the same against dirt and abrasion;
which is easily folded by a small child because of hinge lines
provided along the mat at predetermined locations, thereby causing
the mat to assume a predetermined disposition when folded; which
mat is equipped with pockets permitting articles of clothing and
the like to be kept with the mat where they are conveniently
accessible; and which mat includes a soft, pliable core
substantially covered and enclosed by a casing stitched to the core
along both longitudinally extending and traversely extending lines
at least certain of which establish the aforementioned hinge lines
along which the mat bends when being folded.
Additional objects and advantages of the invention, especially as
concerns particular features and characteristics thereof, will
become apparent as the specification continues.
An embodiment of the invention is illustrated in the accompanying
drawing, in which:
FIG. 1 is a top plan view of a mat embodying the invention, the
cover component thereof being shown in a partially open
position;
FIG. 2 is a bottom plan view of the mat;
FIG. 3 is an enlarged, broken longitudinal sectional view taken
along the line 3--3 of FIG. 2;
FIG. 4 is an end view in elevation of the mat as it is illustrated
in FIG. 1;
FIG. 5 is a perspective view of the mat illustrating the same in a
partially folded condition;
FIG. 6 is a side view in elevation of the mat when completely
folded;
FIG. 7 is an enlarged, perspective view of the mat in the
completely folded position thereof shown in FIG. 6; and
FIG. 8 is a perspective view illustrating the folded mat within a
napsack carrier therefor.
The embodiment of the mat shown in the drawing is indicated
generally with the numeral 10, and in the unfolded condition of use
thereof shown in FIGS. 1 and 2 is a flat, generally planar
structure having substantial length and width. The precise
dimensions of the mat 10 may be varied greatly depending upon the
use intended therefor, and in the case of the mat being used by a
young child, such as a rest mat for kindergarten, may have a length
of four feet and a width slightly less as, for example, about 21/2
feet. As indicated, however, these dimensions are in no sense
critical.
The mat 10, as shown best in FIG. 3, includes a core or pad 11 that
is relatively soft and pliable and may be formed from a great
variety of materials including rubber, cotton batting, and various
synthetic plastics as, for example, polyurethane foam. In the mat
10, the core 11 is a continuous component covered by a casing 12
that may constitute any of a vast number of materials including
natural and synthetic fibers, a fabric such as cotton material, for
example. The casing 12 may completely encapsulate the core 11, as
shown, and therefore has a top or upper face 13 and a bottom face
14 secured to each other wherever appropriate, as by stitching 15
shown in FIG. 3.
The casing 12 is secured to the core 11 along a plurality of lines
at least certain of which form hinge or fold lines along which the
mat tends to bend when folded into the compact pad illustrated in
FIGS. 6 through 8. In more particular terms, the casing 12 is
secured to the core 11 along a plurality of transversely spaced and
longitudinally extending lines of stitching, there being four such
lines in the embodiment of the mat being considered, and such lines
are respectively denoted with the numerals 16, 17, 18 and 19. The
casing 12 is also secured to the core along a plurality of
longitudinally spaced and transversely extending lines, thereby
being five such lines in the mat 10 respectively denoted with the
numerals 20 through 24. The longitudinally extending lines 16
through 19 are substantially parallel, as are the transversely
extending lines 20 through 24; and the two sets of lines intersect
each other as shown in FIGS. 1, 2 and 5.
As shown in FIGS. 1 and 5, the various lines of stitching terminate
a spaced distance from the upper edge of the mat 10 so as to define
a relatively large and unobstructed surface area 25 that serves
somewhat in the nature of a pillow or cushion adapted to receive
the head and face of a child thereon. Also, a cover 26 overlies the
upper face 13 of the casing 12 and is secured thereto such as along
the bottom edge 27 and a portion of the side edge 28. The cover 26
may be releasably secured to the upper face 13 along the upper edge
29 of the mat by a plurality of snap fasteners 30 located adjacent
the corner portions of the mat. Accordingly, the cover 26 may be
fixedly secured along the upper face 13 when the mat is folded for
transport and storage, and may be partially released therefrom to
permit a child to lie down upon the upper face 13 of the casing 12
and wrap himself with the cover 26. The cover 26 may be formed from
the same material as the casing 12 or from an entirely different
material.
The mat 10 along the bottom face 14 of the casing 12 is equipped
with a removable protective sheet 31 which is advantageously formed
of a sturdy, readily cleaned material, such as a transparent
polyethylene, which protects the mat during use and yet can be
wiped clean with little effort. The protective sheet 31 may be, in
the form shown, transparent and may be just slightly larger in
length and width than the casing 12 and removably secured thereto
by a plurality of snap fasteners 32, all as illustrated in FIG.
2.
Also secured to the bottom face 14 adjacent the upper end of the
mat in generally underlying relation with the unobstructed surface
area 25 thereof is a pocket-forming member 33 which may be a fabric
material stitched or otherwise secured to the face 14 along a
transversely extending line 34 and along longitudinally extending
lines 35 and 36. The member 33 is unsecured along its upper edge so
as to provide pockets adapted to receive a smock, cap or other
articles of clothing, etc. therein; and if desired, the member 33
may also be stitched to the face 14 along a median line 37 so as to
form a plurality of separated pockets 38.
The mat 10 is adapted to be folded into a compact package for
storage to facilite portability thereof, and the stitching lines 17
and 18 define or form hinges along which the mat bends or breaks
naturally to facilitate the folding operation which is usually
performed by a small child. Such folding is illustrated in FIG. 5;
and by way of being specific the mat 10 when flat, upon a floor
surface, is shown in FIG. 1, and may be folded normally along one
longitudinal edge portion, along the hinge 17, for example, so as
to bring such edge portion into juxtaposition with the center area
of the mat. Thereafter, the opposite longitudinal edge portion is
folded inwardly along the hinge 18 so as to overlie the opposite
longitudinal edge. Accordingly, in the particular mat 10 being
considered, it is folded longitudinally into three parts or thirds
of substantially equal transverse dimensions.
Next, the lower end portion of the partially folded mat is folded
inwardly along the hinge formed by the stitch line 27. Thereafter,
the upper end portion of the mat is folded thereover, as
illustrated in FIG. 7, which tends to break or bend generally along
the hinge line 23. As a consequence, a relatively flat, compact
package is afforded that may be slipped readily into a napsack 38
having a compartment designed and dimensioned to receive the folded
mat therein. The napsack may have a cover flap 39 adapted to be
secured in covering relation with the mat 10 by a plurality of snap
fasteners 40. Shoulder straps 41 secured to the napsack 38 may
permit the entire unit to be carried on the back of a child with
his arms looped through the straps.
The material used for the casing 12 and cover 26 may be colored and
provided with designs intended to appeal to a child, and the
napsack 38 might also be formed of an attractive material,
patterned as desired. The mat lies flat when in use and is readily
folded and unfolded by a child because of the natural tendency of
the mat to fold or break along the various hinge lines. The
relatively unobstructed upper portion 25 of the face 13 affords a
comfortable place for the child to rest his head and face, and the
cover is convenient to use in that rather large open areas thereof
are afforded to the casing 12 by being attached thereto. The
pockets 38 enable accessories to be carried with the mat so that
they are not readily misplaced or lost and yet do not interfere
with the use of the mat, especially folding thereof.
While in the foregoing specification an embodiment of the invention
has been set forth in considerable detail for purposes of making a
complete disclosure thereof, it will be apparent to those skilled
in the art that numerous changes may be made in such details
without departing from the spirit and principles of the
invention.
