Technical Field of the Invention
[0001] The present invention relates to a stretcher carrier comprising a base susceptible
of being coupled to the inner floor of an emergency vehicle, a platform shiftably
assembled on the base and suitable for supporting the stretcher and drive means driving
the movement of the platform with respect to the base.
Background of the Invention
[0002] In the field of transport of wounded people, sick people or patients by means of
vehicles which are generally called emergency vehicles, such as ambulances, the use
of stretchers for supporting and moving them is widely known. Furthermore, there are
different regulations to that respect which regulate what said stretchers must be
like and how they must be securely fastened to the floor of the vehicles used for
said purpose of transporting and moving people.
[0003] Notably, all the efforts up until now have been aimed at creating stretchers with
an easy manoeuvrability, i.e., for example stretchers which can adopt different positions
according to the need required, such as a position in which the stretcher is at the
height of the floor or in a position in which the stretcher is at a higher position
so that the healthcare personnel can care for the patient in situ without having to
bend down. Another type of development has been aimed at offering systems or devices
allowing the secure fastening of the stretcher inside the vehicle, for the purpose
of preventing the stretcher from moving inside the vehicle during its transport or
systems allowing the regulation of the height of the stretcher inside the vehicle.
[0004] Furthermore, there is another type of development which is aimed at providing the
stretcher or systems associated therewith with elements which allow supporting objects
or devices necessary for treating the sick people and/or wounded people who are being
cared for during their transport from the site of the accident to the corresponding
hospital centre.
[0005] All these developments are also accompanied by automatic, hydraulic or electric systems
facilitating the different operations and movements which may be performed by the
healthcare personnel with the stretchers such as the lifting of the bed with respect
to the floor or the movement of the base when the stretcher is loaded or unloaded
from the vehicle.
[0006] Even so, all the known developments are deficient in that although the healthcare
or emergency personnel have more elements and features for their work and the safety
of the patients, such personnel are prone to suffering from considerably back injuries
due to the physical efforts that they must still make in order to perform the tasks
of loading and unloading the patient or sick person.
Disclosure of the Invention
[0007] For the purpose of providing a stretcher carrier solving the problems set forth above,
a stretcher carrier is disclosed which comprises a base susceptible of being coupled
to the inner floor of an emergency vehicle, a platform shiftably assembled on the
base and suitable for supporting at least one stretcher and drive means driving the
movement of the platform with respect to the base.
[0008] The stretcher carrier object of the present invention is essentially
characterized in that the platform comprises motor-operated driving means for the stretcher, suitable for
fastening the stretcher and for shifting it longitudinally above the platform from
a coupling position to a loading position in which the stretcher rests on said platform.
[0009] Advantageously, with the installation in the stretcher carrier of said driving means
it is not necessary to use the strength and effort of the emergency personnel to load
and unload the stretchers in the emergency vehicles as occurs in current stretcher
carriers and which inevitably entails considerable injuries to said personnel.
[0010] According to another feature of the invention, the driving means comprises fastening
means for fastening the stretcher, longitudinally shiftable along respective guides
provided for such purpose on the surface of the platform.
[0011] According to another feature, the fastening means comprises a nut coupled by screwing
to a motor-operated rotating spindle, the fastening means being prevented from rotating
by means of the respective guides, such that the rotation of the spindle in one direction
or another causes the longitudinal shift of the fastening means along the guides towards
one end or another of the platform, respectively.
[0012] According to another feature, the fastening means comprises at least one hook. Said
hook of the fastening means is sinkable, being susceptible of adopting at least two
positions, a sunken position with respect to the platform and an extracted position,
in which the hook is subjected to the action of elastic means maintaining it in said
extracted position, especially suitable for fastening the stretcher.
[0013] According to another feature, the fastening means further comprises stop means adjacent
and complementary to the hook which facilitate the secure fastening of the stretcher
and prevent it from moving.

Detailed Description of the Drawings
[0015] The stretcher carrier 1 depicted in Figures 1 to 5 comprises a base 2 suitable for
being coupled to the inner floor of an emergency vehicle, not depicted, a platform
3 shiftably assembled on the base 2 and drive means 4 connecting and driving the movement
of the platform 3 with respect to the base 2.
[0016] The platform 3 is the one suitable for receiving and supporting at least one stretcher,
not depicted. In Figure 2, part of the platform 3 has been concealed, specifically
the outermost surface thereof and which is where the stretcher to be supported rests,
in order to be able to observe other details of the stretcher carrier 1 of the invention
which are described below.
[0017] It should be mentioned that the drive means 4 connecting and linking the platform
3 with the base 2 are formed by an electric system which allow the lifting of the
platform 3 with respect to the base 2 (see arrow A of Figure 3), as well as the tilting
of the platform 3 on the horizontal (see arrow B). Furthermore, it is provided that
said drive means 4 are hydraulic in other embodiments.
[0018] In addition to these elements, the platform 3 of the stretcher carrier 1 comprises
motor-operated driving means 6 for the stretcher. Said driving means 6 are suitable
for allowing the fastening of the stretcher and for being able to shift it longitudinally
above the platform 3 from an initial coupling position to a loading position in which
the stretcher rests on said platform 3.
[0019] Specifically, as observed in Figures 1, 2 and 3, the driving means 6 comprise fastening
means 61 for fastening the stretcher. The platform 3 is provided with respective guides
62 on its surface allowing the mentioned fastening means 61 to shift longitudinally
along them, and therefore the stretcher. This shift of the fastening means 61 is due
to the fact that the mentioned fastening means 61 comprise, as observed in Figure
2, a nut coupled by screwing to a motor-operated rotating spindle 63, the fastening
means 61 being prevented from rotating by means of the mentioned respective guides
62, such that the rotation of the rotating spindle 63 in one direction or another
(see arrow C) causes the longitudinal shift of the fastening means 61 along the guides
62 towards one end or another of the platform 3, respectively (as indicated with arrow
D).
[0020] Together with said longitudinal shift movement of the fastening means 61 with respect
to the platform 3 of the stretcher carrier 1 and with the tilting movement caused
with the drive means 4 connecting the platform 3 with the base 2, the loading, unloading
and handling of the stretcher in the stretcher carrier 1 are allowed without needing
to use the physical effort of the healthcare and emergency personnel handling said
stretcher carrier 1.
[0021] In the embodiment depicted in the figures it is observed that the fastening means
61 are formed by two hooks, which are sinkable, i.e., they are susceptible of adopting
at least two positions: a sunken position with respect to the surface of the platform
3 and an extracted position, in which the hooks are subjected to the action of elastic
means maintaining them in said extracted position, especially suitable for fastening
the stretcher.
[0022] The fastening of the stretcher during the operations of loading and/or unloading
the stretcher of the stretcher carrier 1, even its fastening when the stretcher is
supported in the platform 3 of the stretcher carrier 1 during the transport of the
patient or wounded person in the emergency vehicle, is allowed by means of said hooks
of the fastening means 61.
[0023] In a complementary manner, it is provided that the fastening means 61 further comprise
stop means adjacent and complementary to the hook which facilitate the secure fastening
of the stretcher and prevent it from moving, i.e., the correct fastening of the stretcher
in the stretcher carrier 1 without it being accidentally released from the fastening
means 61 is thus ensured.
[0024] It must be emphasized that this stretcher carrier 1 is suitable for fastening and
driving the stretchers which are conventionally used and in accordance with the regulations
required in this type of system and mechanism used by emergency services.
