Description
BEDS AND MATTRESSES
This invention relates to beds and mattresses, and more particularly to
beds and mattresses incorporating a plurahty of springs, the aim of the
invention being to provide a sprung bed or mattress in which the firm¬
ness of the bed or mattress may be varied by varying the compression
of the springs of the bed or mattress, or some at least of said springs.
There has been several prior proposals for providing such beds or
mattresses, but such prior proposals have all been complex in nature
see for example United States Patent Nos 3,739,409 (Johnson) and
2,724,842(Rogovy). Both of these prior United States patents
proposed complicated and expensive constructions for varying the
compression of the springs of a bed or mattress, and the present
invention seeks to obviate the drawbacks and disadvantages of these
and other proposals.
According to one aspect of the present invention there is provided a
bed or mattress including a plurality of springs which, or some at least
of which, are movable in their axial directions so as to vary the
compression of the springs or some at least of said springs, without
materially or substantially changing the position of the upper surface
of the bed or mattress.
The springs may be coil springs, pocketted springs, double pocketted
springs, helical springs, or any other suitable springs.
The bed or mattress will preferably include a base to which the
springs, or some of the springs, may be directly or indirectly secured,
said base being movable in the axial direction of the springs so as to
vary the compression of said springs or some at least of said springs,
an upper surface of said bed or mattress remaining in the same
horizontal plane or substantially the same horizontal plane regardless
of the degree of compression of said springs or some at least of said
springs and the position of said base.
The base may be formed as a single structure or alternatively the base
may be formed of a plurality of sections movable independently of one
another so that the compression of the springs may be varied in
selected areas or in a selected area of said bed or mattress.
The springs will be arranged in rows each surrounded or partially
surrounded by fabric, or alternatively two rows, three rows, or more
may each be surrounded or partially surrounded by a single piece of
fabric or other material. Alternatively, the rows of springs or some of
said rows of springs may be secured directly to said base, hi yet a
further alternative, adjacent rows of springs or groups of rows of
springs may be adhesively secured together and a bar or other means
may be located between said rows or groups of rows of springs.
The springs will preferably be single pocketted springs, double
pocketted springs, i.e. a pocketted spring within a pocketted spring,
pocketted springs arranged in end-to-end and co-axial relationship, or
a combination thereof.
The base or a part or parts of said base may be moved in the axial
direction of the springs by means of one or more air bags, screw
motors, electric motors, or by means of jack handle(s) or by any other
suitable means, the number of such means being a matter of choice.
According to a second aspect of the present invention there is provided
a method of varying the compression of the springs or some at least of
the springs of a bed or mattress including a plurality of springs
secured directly or indirectly to a base of said bed or mattress, the
method comprising moving the base or at least a part or parts of the
base in the axial direction of the springs whilst mamtaining an upper
surface of the bed or mattress in the same horizontal plane or
substantially the same horizontal plane regardless of the degree of
compression of the springs and the position of said base.
In order that the invention may be more readily understood,
embodiments thereof will now be described, by way of example only,
reference being made to the accompanying drawings, wherein:
Figure 1 is a diagrammatic representation of a plurality of springs
forming part of a bed or mattress according to the invention;
Figures 2 and 3 are views similar to Figure 1, but showing alternative
arrangements of the springs;
Figures 4 and 5 show how the rows of springs are secured together
when forming the bed or mattress;
Figure 6 is a view similar to Figure 1 and shows a base forming a part
of the bed or mattress; and
Figure 7 is a view similar to Figure 6, but showing the base or a
portion of the base in a different position during compression of some
of the springs of the bed or mattress.
Referring to the drawings, and firstly to Figure 1, there is shown a
plurality of pocketed springs arranged in side-by-side rows, one spring
of each row being indicated by the reference numerals 2 to 16, it being
understood that the whole bed or mattress will comprise more rows of
springs than is shown in Figure 1. As will be seen, each of the springs
2 to 16 are pocketted springs and in fact are double pocketted springs
in that each spring comprises an outer spring and an inner spring
which is itself a pocketted spring.
The double pocketted springs of each row of springs is enclosed in a
shroud of fabric or other suitable material, one of such shrouds being
indicated by reference numeral 18, it being understood that all of the
other shrouds are identical. Each of the shrouds, such as that which is
indicated at 18, is open-ended at its lower end as clearly shown in the
drawing, the lower ends of the shroud being secured by suitable means
to a rigid or semi-rigid base, not shown in Figure 1.
Referring now to Figure 2, it will be seen that two rows 20 and 22 of
double pocketed springs are enclosed by a shroud 24, whilst in Figure
3, three rows 26,28, and 30 are enclosed by a single shroud 32, the
ends of the shroud 24 and the ends of the shroud 32 again being
secured to a rigid or semi-rigid base of the bed or mattress.
Instead of the shrouds 18, 24, and 32 being discrete shrouds, such
shrouds may each be formed as a single continuous shroud.
Referring now to Figure 4, this shows a plurahty of rows of springs
such as those shown in Figure 1 and shows the rows of pocketted
springs secured together by adhesive 40A. Bars 40 running down the
length of the rows are intended, in co-operation with the adhesive 40A,
to prevent the whole row rising when the compression of the springs or
some at least of the springs is varied as will be explained hereinafter.
The bars are secured by suitable means to the base, the perimeter or
other area of the bed or mattress such that they are not movable relative
to the upper surface of the bed or mattress.
Although Figure 4 shows the bars 40 and adhesive 40A at
approximately the middle position of the springs - in the uncompressed
states - it will be appreciated that such bars and adhesive may in fact
be located at any position along the length of the springs, including the
lower extremities of the springs.
Figure 5 shows a view similar to Figure 4, and illustrates the securing
of a number of the rows of pocketted springs to a base, such secure-
ment being indicated by reference numerals 42 and being provided to
prevent the attached rows from rising when the compression of the
springs or some of the springs are varied. Again, the rows of springs
are secured together by adhesive.
Referring now to Figure 6, this shows the rows of springs in Figure 5
secured to a base forming part of the bed or mattress, the base being
indicated generally by reference numeral 50. The base 50 in fact is
formed of a number of sections - indicated by reference numerals 50A,
50B, and 50C - the centre section 50B being movable in the axial
direction of the springs by means indicated at 52, such means being,
for example, one or more air motors, screw motor(s) electric motor(s)
or by any other suitable means.
Figure 6 illustrates the centre section 50B in its inoperative position in
which the springs are in their normal 'uncompressed condition,
whereas Figure 7 shows that the centre section 50B has\been raised,
thereby compressing the associated springs to the positions shown in
the Figure so as to change the firmness of the bed or mattress.
Whilst Figures 6 and 7 show only the centre section 50B as being
movable, it will be appreciated that the other sections 50A and 50C of
the base may also be movable. In fact, the whole base - formed as a
single structure - may be movable so as to vary the compression of all
of the springs of the bed or mattress. Indeed, the base maybe formed
such that it is formed of the same number of sections as there are rows
of springs, in which case the compression of the springs in each
individual row of springs may be changed independently of the springs
in all the other rows.
The fact that the rows of springs are secured together by adhesive
results in the uncompressed springs not moving upwardly when the
base or a part or parts of the base is or are moved.
In addition, where the springs are double pocketted springs, the ove-
ment of the inner pocketted spring relative to the outer pocketted
spring, without any movement of the outer pocketted spring, results in
an increase in the firmness of the bed or mattress.
Thus the invention provides a method of varying the compression of
the springs of a bed or mattress without raising or lowering the upper
surface of the bed or mattress so as to vary the firmness of the bed or
mattress and thereby provide a bed or mattress whose firmness can be
adapted to suit varying requirements of individual user of the beds or
mattresses.
It will be appreciated that whilst the illustrative examples of the
invention have been related to double pocketed springs, the springs
may be single pocketed springs or indeed any other type of spring
normally associated with beds and mattresses.
Finally, whilst the invention has been related to beds and mattresses, it
will be understood that the invention is equally applicable to other
items of upholstered units where firmness adjustment is desirable.
