1 Claim.
(c1. unease)v
This invention relates to new and useful im
provements in a double tie sheet for beds.
The invention has for an object the construc
tion of a device as ‘mentioned which is adapted
to be used in combination with a bed having
longitudinal‘ side horizontal bars beneath the
mattress thereof, and‘vertical side bars at the
sides thereof.
' More particularly, the double tie sheet accord
10 ing to this invention is characterized by a bottom
sheet of the width of the mattress of said bed
and having cords or the like at the sides adapted
to be attached to said horizontal bars, and a
top sheet of the width of said mattress and hav
“ ing cords or the like at the sides, and the cords
at the rear portion thereof being adapted to be
attached on said side horizontal bars and the
cords at the front portion thereof being adapted
to be slidably connected with said vertical bars.
A further object of the invention is the arrange
20
ment of the front cords upon the edges of the
top sheet so that they may be removed and re
placed in different positions.
.
A feature of the constructions described in the
25 previous paragraphs is that the possibility of a
baby being strangled by the sheets is entirely
eliminated since the top sheet is yieldable in that
the front strings thereof may slide on the bars.
A further object of the invention is a con
30
struction whereby the front portion of the top
sheet cannot be tied down to the horizontal bars
so as to make the device fool proof.
Another object is the construction of a device
as mentioned which is simple and durable and
which‘ may be manufactured and sold at a rea
sonable cost.
For further comprehension of the invention,
and of the objects and advantages thereof, refer
ence will be had to the following description and
40 accompanying drawing, and to the appended
claim in which the various novel features of the
invention are more particularly set forth.
In the accompanying drawing forming a ma
terial part of this disclosure-—
Fig. 1 is a perspective view of a bed to which
a double tie sheet, according to this invention,
may be applied.
Fig. 2 is a fragmentary transverse sectional
view of the bed ‘shown in Fig. 1 witha mattress
and a double tie sheet according to this inven~
tion thereon.
Fig, 3 is a side elevational view of a mattress
with the bottom sheet according to this invention
55 engaged thereon.
Fig. 4 is a perspective View of the bottom sheet
per se.
Fig. 5 is a longitudinal sectional view of a mat
tress with the double sheet engaged thereon.
Fig. 6 is a perspective view of the top‘ sheet.
Fig. 7 is a fragmentary perspective View similar
to a portion of Fig. 6 but showing a modi?cation.
Fig. 8 is a sectional view taken on the line
8—8 of Fig. 7.
The double tie sheet, according to this inven- ‘
tion, comprises a bottom sheet II) of a width sub
stantially corresponding with the width of a
mattress IIa to which the sheet is to be engaged.
This bottom sheet I0 is provided with cords II
at the sides thereof at the front and rear por 15
tions. These cords are adapted to be attached
upon horizontal bars I2 of a bed to which the
device is applied. In conjunction with the bot
tom sheet I0 there is a top sheet I3 also of the
width of the mattress, which has cords I4 or
the like at the sides at the rear portion thereof
and which has other cords I4’ also at the sides
but at the front portion thereof.
The rear cords I4 are adapted to be tied to the
horizontal bars I2 of the bed so as’ to hold the 25
sheet in position. The front cords I4’ are
adapted to be slidably tied to the vertical bars
I5 of the bed.
This invention is intended only to be used in
combination with beds having horizontal bars
for supporting the spring and mattress for the
bed, such as the bars I2, and also having verti
cal slide bars such as the bars I5.
The bottom sheet I0 is adapted to have its
end portions I0a and Illb tucked under the front
and rear ends of the mattress. The rear portion
I39‘ of the top sheet I3 is adapted to be tucked
under the rear end of the mattress, while the
front end I3b is adapted to be bent rearwards a
short distance so as to be at a convenient height 40
for a child sleeping in the bed.
The front cords I4’ are rel-easably laced through
button holes I6 formed along the sides of the
sheet I3. When desired, the cords may be re
moved from certain of the button holes and en 45
gaged in others of the button holes.
In Figs. '7 and 8 a modi?cation of the inven
tion is disclosed in which the top sheet I3’ has
rigid inserts I8 mounted on the ends thereof.
These inserts may be of composition rubber or
other stiff material. Each of these inserts is
formed with an opening I9 having a reduced
mouth I9a. Cords or the like III" are secured
together at their inner ends and are connected
with buttons 2| which are adapted to engage be 55
2
2,137,012
neath the inserts l8. Each button 2| is of a
larger diameter than the opening [9 so that as
long as the cords H" are drawn upwards, the
parts remain connected. Should the cords ll"
be moved relatively downwards they may pass
between the restricted area l9n and so disconnect
from the insert.
'
Bushings 20 are slidably mounted upon the ver
tical bars l5 and are adapted to frictionally main
10
tain adjusted positions. Preferably, these bush
ings should be of rubber. The cords [4" are
adapted to be tied upon the bars l5 above the
bushings so that they are restrained from. slip
ping downwards. The bushings 20 must be at a
15 suflicient height so that the front portion of the
top sheet l3 may be raised as is required when a
child sleeps beneath it, but at the same‘ time, to
prevent the disengagement from the cords I4"
through the'mouths I9“. If the child sits up
20 there is a relative movement between the front
portion of the sheet l3 and the cords [4".
Should these cords slide upwards there will be
no disconnection, but should the cords maintain
their positions, the cords will disengage from the
inserts of the sheet.
The feature of the invention resides in the fact
that the sheets are held in position. They will
not slip upwards or downwards as is customary
with standard sheets, especially if they are of in
30 su?icient size so that the edges and ends thereof
may not be properly tucked under the mattress.
While the sheets are tied down the front portion
of the top sheet is loose or may be freed so as to
prevent any strangulation of the baby.
While I have illustrated and described the pre
ferred embodiment of my invention, it is to be
understood that I do not limit myself to the pre 5
cise construction herein disclosed and the right
is reserved to all changes and modi?cations com
ing within the scope of the invention as de?ned
in the appended claim.
Having thus described by invention, what I
10
claim as new and desire to secure by United
States Letters Patent is:
A separable fastener of the type described,
comprising a stiff sheet-like member having a
narrow opening in one edge thereof merging into 15
an opening of increased size inwardly thereof
forming shoulders, and a button-like member
having one or more ?at bendable securing-tapes
attached at one of their ends to one face of said
button-like member, said edge opening being
20
only of a width sufficient to receive said tapes
edgewise, said tapes being within said larger
opening, said button having its said face abut
ting the material of said member around said
larger opening to prevent said tapes from being
pulled axially from said larger opening and said
tapes having their edges abutting said shoulders
to prevent said tapes from being pulled through
said narrow opening in their crosswise position
except when an excess pull is applied thereto.
