Description
TECHNICAL FIELD
[0001] The invention concerns a safety feature for a children's bed
with a guard rail for use primarily on children's beds in
hospitals, medical institutions, and home care. The safety feature
uses freely rotating elements to prevent the patient from falling
out of the bed.
BACKGROUND OF THE INVENTION
[0002] The protection of a patient's health is the most important
parameter for patient care whether in a hospital, an institution,
or in home care. If it involves the protection of a child patient's
health, then greater emphasis is placed on their safety. For this
reason, the mechanisms and accessories preventing the patient from
falling out of the bed accidentally and against the potential risk
of injury are constantly being improved. The majority of the
inventions concern the actual mechanisms of the side rails.
[0003] Document CN200987523 contains a well-known state of the art
describing a protective element for children for placement on an
adult bed, and represents a bottomless enclosure whose side walls
are filled with textiles.
[0004] Documents CN203563978 and CN204071378 describe a children's
bed that is protected by an insect net connected to a column. The
primary use of these inventions is the protection of child patients
from insects, thereby ensuring greater comfort for the child. A
secondary function is a barrier preventing the child from falling
out of the bed.
[0005] Other well-known children's beds that are equipped with a
guard rail to prevent unwanted falling out of bed comprise side
rails and ends made of impermeable material, wooden bars, or
textile nets.
[0006] An example of such a bed is, for example, document U.S. Pat.
No. 7,003,823, which describes a children's bed whose side walls
are constructed with a protective net.
[0007] In all of the aforementioned documents the protection of the
children's bed against climbing out is primarily made by high
enclosures. This height is specified by a technical standard. The
disadvantage of these solutions is that the barrier that would
safely secure the children's bed against children climbing out
would not permit the simultaneous manipulation with the child on
the bed surface, making it necessary to mechanically lower the
height of the side rails for such manipulation. This is primarily
unsuitable for hospitals where child patients spend all of their
time in bed and it is necessary to have easy and continual access
to them.
SUMMARY OF THE INVENTION
[0008] The drawbacks of the current state of the art are resolved
by attaching a safety feature to the frame of the children's bed
with guard rails against climbing out, according to the submitted
invention attached. The safety feature contains beams with lengths
corresponding to the dimensions of a bed arranged to form a
structure whose shape and dimensions correspond to the shape and
dimensions of the children's beds. The beams provide the benefit of
a circular cross-section, permitting a continuous row of axially
symmetric elements also of circular cross-section to freely rotate
around each beam, while the ends of the beams have a means for
attachment. A spacer may be placed between the elements, limiting
the creation of larger spaces between them, allowing their even
division on the beam. The beams have the benefit of being tubes
made of metal or plastic.
[0009] The continuous row of elements on the beams makes it
impossible to directly grasp the beam between the individual
elements. Thanks to the elements rotating freely around the beam,
it is impossible to grasp and prevents the child climbing over the
bed's safety feature, even when the side rails are of lower height,
and allows easier manipulation of the child in the bed.
[0010] The safety feature can include devices for attachment to the
upper part of the children's bed's frame. The attachment devices
are advantageously located at the end of the beams and are adapted
for attachment to the upper part of the support columns. The height
of the attachment devices limits the distance of the beams from the
upper edge of the children's bed, while the height of the
attachment device is chosen to prevent injury to the child becoming
caught in or by attempting to climb out through the space created
between the lower parts of the elements and the upper edge of the
children's bed. In one version of the invention the attachment
device contains an insertable vertical pin for an opening on the
support column. The height of this pin can be adjusted.
[0011] In a suitable implementation the elements are axially
symmetric along the longitudinal axis of rotation, which passes
through the opening for inserting the beam, while the diameter of
the opening of an element is greater than the diameter of the beam.
The elements are made with a smooth surface and non-toxic
materials, i.e. a suitable plastic.
[0012] The distances of the bars from the upper edge of the side
rail and from the upper edge of the entire bed are selected to
prevent the danger of injury to the child becoming caught in or by
attempting to climb out through the space created between the lower
parts of the elements and the upper edges.

EXAMPLES OF IMPLEMENTING THE INVENTION
[0019] FIG. 1 shows a safety feature 1 for a children's bed 2 with
a guard rail 3 against climbing out of the bed according to the
invention, which is arranged for attachment to the frame 4, which
can be the ends 6 of the bed 2, the side rails 5 or the support
columns 15. The children's bed 2 contains an undercarriage or
static lower section, a mattress platform and a guard rail 3
containing side rails 5 and the bed end 6. In a suitable
implementation the guard rail 3 is removable or height adjustable,
as can be seen in FIG. 1, where the side rail is in the lower
position and in the middle position, though the side rails 5 can be
placed in the upper position, where its upper edge is on the sale
level of the upper edge of the bed end 6. The safety feature 1
contains beams 7 with a length corresponding to the dimensions of
the children's bed 2, arranged in a structure corresponding to the
bed 2 in terms of shape and dimensions. The beams 7 provide the
benefit of a circular cross-section. Each beam 7 is equipped with a
row of elements 8 freely rotating around the beam 7, while the ends
of the beams 7 are equipped with a means for attachment 10. In a
suitable implementation the elements 8 do not intrude over the edge
of the mattress platform.
[0020] FIG. 2a depicts a suitable implementation of an element 8,
which is equipped with an opening 9 for placement on the beam 7.
Each element 8 is borne by the beam 7 so that the axis of the beam
7 passes through the axis of the rotating element 8, as is evident
in FIG. 2b, which depicts a cross-section of an element 8, which is
borne by the beam 7. A suitable implementation for this
characteristic is the placement of the axis (in the case of a
rotating element) or the centre of gravity (in the case of an
element with an irregular shape) of the element 8 close to the axis
of the beam 7. The ideal bond for this implementation is a coaxial
or rotational bond. In a suitable implementation the elements 8 are
round in shape, though in an alternative implementation they can be
any shape, since free rotation around the beam is important for the
purpose of the invention. The dimensions and number of elements 8
are adapted so that a continuous row of bodies 8 without spaces is
created, thus preventing the direct grasping of the beam 7 by a
child's hand. In an alternative implementation the shape of the
element 8 that is attractive to a child patient can be used, e.g. a
combination of shapes of angular bodies with round bodies, or it is
also possible to make it more attractive by combining materials
with a different reflexivity of various wavelengths. In another
alternative implementation the element 8 can be hollow and filled
with material that generates sounds when the element 8 moves.
[0021] In an alternative implementation it is possible to use only
one rotational body 8 corresponding to the length of the and be
wound around the beam's 7 entire length. An example of this
alternative would be a tube encircling the entire beam 7.
[0022] In an alternative implementation it is possible to place at
least one limiting unit 11 on the beam 7 to fill the space between
the elements 8 if their total length does not entirely correspond
to the entire length of the beam 7. This limiting unit 11 is seen
in FIG. 3. The limiting unit 11 can also be rotational.
[0023] The safety feature 1 is meant to be attached above the guard
rail 3 of the bed 2, as can be seen in FIG. 3. In a suitable
implementation the shorter beams 7 are solidly attached using a
means of attachment 12 to connect it to the longer beams 7, though
in an alternative implementation they can also be connected to each
other in the opposite manner. The longer beams 7 are solidly
attached using a means for attachment 13 to the frame 4 using a pin
14. In the given example the frame 4 is represented by the columns
15 of the children's bed 2, as can be seen in FIG. 4. In an
alternative implementation the shorter beam 7 may be attached to
the longer beam 7, which is attached to the frame 4. In another
alternative implementation, the beams 7 can be attached using
common means for attachment 8 at the same level. There is also
another way to attach the safety feature 1 to the children's bed 2
that a regular expert knowledgeable in the state of the art is
capable of implementing.
[0024] The safety feature 1 includes in the corners a means 10 for
attachment to the frame 4 of the children's bed 2. The means 10 for
attachment to the frame are equipped with a vertical pin 14 that is
inserted into an opening in the frame 4. The height of the pin 14
determines the distance of the beam 7 from the relevant upper edge
of the children's bed or the distance between the lower part of the
elements 8 and the upper part of the children's bed 2. The height
of the pin 14 is chosen to prevent injury to the child becoming
caught in or by attempting to climb out through the space created
between the lower parts of the elements 8 and the upper edge of the
children's bed 2. In an alternative implementation the safety
feature 1 can be attached separately to the side rails so that it
moves together with the side rails.
[0025] In an alternative implementation the safety feature 1 is
removable, either whole or in part.
