DOOR SAFETY DEVICE
This invention relates to a door safety device. It relates particularly to a
device for fitting
at the hinge side of a door and door frame in order to reduce the risk of
injury to a child's fingers
if they should attempt to enter this space.
When a door is in the open position, the hinge side of the opening between the
door side
and the door frame offers a gap into which a young child's hand or fingers can
very easily be
inserted. If the door should then be closed, possibly by another child or by
pressure from a
draught of wind, there is a serious risk that the hand or fingers will become
hurt or badly
damaged. In time, of course, any child will learn that the gap at the edge of
a door that is being
closed is a dangerous area in the home and any fingers should be kept well
away from this zone.
However, the younger child will not be aware of this risk and may suffer a
crushed finger.
The present invention was devised to provide a shield that would reduce the
risk of injury
to a child's hand.
According to the invention, there is provided a door safety device comprising
a cover for
a gap at the hinge side of a door and door frame combination, the cover
comprising a strip of
rigid material which is flexible about its major axis, said strip having first
and second long edges,
the strip having attachment means at its long edges so that the fwst edge may
be secured to the
door and the said second edge to the door frame of the combination, the
securing means being
such at one edge is firmly fixed to one of the door/door frame combination
whilst the other edge
is fixed in a manner that allows a vertical movement of that edge with respect
to the other
member of the doorldoor frame combination, and the cover being formed with
rigid portions and
longitudinally-directed hinges, the arrangement being such that a vertical
edge of a door when
present forms a support for one rigid portion of the device whereby the device
will be maintained
in a generally convex attitude whilst the door is being opened and closed.

The cover may be formed of four rigid portions connected by three fold areas.
The cover
may be made of a fibrous or fluted board material.
The attachment means at one side of the strip may include the strip edge being
formed in a
T-shape and this edge being positioned in a C-shaped housing which will hold
the T-shape
yet allow the necessary vertical movement.
By way of example, some particular embodiments of the invention will now be
described
with reference to the accompanying drawings, in which:
Figure 1 is a partial horizontal cross-sectional view through a door and door
frame when
fitted with the door safety device,
Figure 2 is a view similar to that of Figure 1 when the door has been opened
through an
angle of sixty degrees,
Figure 3 is a similar view when the door has been opened fully,
Figure 4 is a cross-sectional view through the safety device,
Figures 5 and 6 are similar views of a different embodiment of safety device,
Figures 7 and 8 show a further embodiment, and,
Figure 9 depicts on a reduced scale a view of a door and door frame with a
fitted safety
device.
As shown particularly in Figure 1, the safety device is intended to be fitted
at the hinge
side of a door located in a door frame so that it will cover the large gap
that appears when the
door is opened. It is not necessary for the device to extend the full length
of the vertical door
side because a young child cannot be expected to reach very far up the door
side. Therefore,
a cover which extends a little more than halfway up the door side is likely in
practice to be
sufficient protection.

Figures 1 to 3 show the door being opened to different angles with respect to
the door
frame. The door 1 is mounted on hinges 2 that are located on the door frame 3.
The safety
device 4 is adhesively secured at one side to the door 1 and at the other side
to the door frame
3. When the door is in the closed position (Figure 1), the safety device 4
forms a flattened
shape which occupies the corner where the door and frame come together. As the
door is
opened, the device 4 unfolds into a generally convex shape (Figures 2 and 3)
which will tend
to cover over the gap that appears with the greater angle of opening. A
child's fingers will
thus be prevented from entering this gap so there will be a reduced risk of
accidental damage
when the door closes. Upon closure of the door, the safety device 4 becomes
folded again so
that it will return to the position of Figure 1.
Figure 4 shows a cross-sectional view of the safety device which was made of a
PVC
composition with sections of rigid and flexible material. At the left hand
side, the view
depicts a T-shaped foot 6 which carries an adhesive pad 7. The foot 6 is
attached by means
of a fold area 8 to a rigid portion 9 and then by a further fold area 8 to a
second rigid portion
11. The second rigid portion 11 is attached by another fold area 8 to a plate
12 on which a
further adhesive pad 7 is located.
In operation of the safety device, the pads 7 are secured in the positions
shown in Figure 1
to the door and door frame. The installation is effected with the rigid
portions (9,11) being
bent about their connecting fold area 8. Upon opening the door 1, the rigid
portions (9,11)
then unfold from one another and open outwards so that a convex shield is
provided over the
door edge gap. When the door reaches the position depicted in Figure 3, the
second rigid
portion 11 is seen to lie in contact with the flat surface of the door 1 so
that the door edge 13
forms a fulcrum for supporting the rigid portion 11. The door edge 13 thus
serves to

maintain the convex shape of the safety device 4 so that it is unlikely to be
distorted by
pressure from a child's fingers.
Figures S and 6 show a further embodiment which is particularly suitable for
being made
from a board material such as a rigid cardboard, a fluted board or a board
made of a plastics
material. The different parts have the same reference numerals as those
already described. In
Figure 6, the fold areas 8 are made by a creasing operation on the board.
Whilst the embodiments already described are suitable for use on doors with
conventional
door hinges, there is also in common use a different hinge termed a rising-
butt hinge which
allows a small vertical movement of the door upon opening so that a raised
carpet edge can be
cleared. The embodiment shown in Figures 5 and 6 is readily adapted for this
type of hinge
since the board material of the device can be allowed vertical movement by
providing a
vertical column of diagonally directed slits along the length of the device.
There are also
other ways of obtaining the vertical movement capability such as combinations
of cutting and
creasing and these techniques will be well-known to those familiar with this
material.
In order to provide a safety device that was suited to both conventional and
rising-butt
door hinges, the embodiment shown in Figures 7 and 8 was devised. In this
construction,
the foot 6 is replaced by an anchor 14 in the shape of a letter T which is
capable of being
secured in a C-shaped housing 16. The housing 16 is provided with its own
adhesive pad 7
by which it may be attached to the door frame 3. The housing 16 thus forms a
secure fixing
for the anchor 14 but it permits the anchor to move up and down along the
housing as may be
required to compensate for the vertical movement of a door mounted on rising-
butt hinges.
Figure 9 shows a door 1 located in a door frame 3 with the safety device 4 of
the invention
mounted at the hinge side of the door 1. It will be seen that the device 4
does not need to

extend up the full height of the door because a young child will not be able
to reach much
more than halfway up the door. The safety device 4 is designed to fold
automatically upon
closure of the door so that it can remain unobtrusive in appearance.
The foregoing description of embodiments of the invention has been given by
way of
example only and a number of modifications may be made without departing from
the scope
of the invention as defined in the appended claims. For instance, instead of
the safety device
edges being secured by adhesive pads, an alternative method such as screw
fixings could be
used. The plastics material used for the safety device has been described as a
combination
of rigid and flexible PVC material. This is preferably a translucent PVC or
even a PVC that
has been given a light blue tint. It is also preferred that the safety device
will have an
unobtrusive appearance when it is located on the protected door and there are
likely to be
many other plastics and alternative materials that will fulfil this object.
