OBJECT OF THE INVENTION
[0001] This specification refers to a Utility Model application, relating to an improved
hand-driven cart to transport coffins, the purpose of which is evidently to transport
a coffin with a body inside. The surface that supports the cart can be adjusted to
a variety of heights in order to simplify the operations involved in transporting
the coffin with its contents on the cart itself, such as from the funeral parlour
to the hearse and vice versa. By making use of the independently activated hydraulic
pumps, the support surface can be adjusted to a diagonal position. The operations
of elevating and lowering the surface are carried out by means of pedals, which directly
act upon the pumps involved, together with the relevant support mechanism.
[0002] The height of the invention, thanks to its lifting and lowering mechanism, can be
lowered in order to reduce its total volume for storage or transport purposes.
FIELD OF THE INVENTION
[0003] This invention is applicable in the industry dedicated to the manufacture of carts,
lift-trucks and similar articles.
BACKGROUND OF THE INVENTION
[0004] The applicant is aware of the existence of a large number of hand-driven carts designed
to transport coffins, the common denominator of which are the wheels that move the
cart and a rectangular surface on which the coffin is positioned, with a gripping
area to guide it when being moved and having the whole of it a closure around the
perimeter, either flexible or not.
[0005] However, during the many operations involved in the moving and transport of coffins,
it can be seen that the transport vehicles that operate as hearses, pathology vans
and others, have different heights, in which case the persons in charge of the transport
have to be aided by other employees to move the coffins containing bodies, if the
carts used for this transport are not of the same height as the vehicle.
[0006] The evident solution to this problem would consist of using an improved hand-driven
cart on which the upper surface is capable of being positioned at different heights.
This height adjustment needs to be a simple operation, aligning the cart with the
surface of the vehicle in which the coffin containing the body is to be taken to the
cemetery or to the funeral parlour, or even when the body is to be autopsied and therefore
has to be placed at the disposal of a pathologist before the burial.
[0007] However, the applicant is unaware of the existence of an invention equipped with
these suitable characteristics.
DESCRIPTION OF THE INVENTION
[0008] The improved hand-driven cart to transport coffins proposed in this invention is
an element designed to transport coffins which, in addition to being lowered and raised
in height, can also be positioned on a diagonal plane by raising either the front
or the rear of its surface.
[0009] More concretely, the improved hand-driven cart to transport coffins which is the
subject matter of this invention is based on a metal structure or framework which
constitutes its rigid structure, and is sufficiently resistant for the purpose for
which it is intended.
[0010] On the top of the invention there is a rectangular surface made of stainless steel
plate, whereas on the bottom, and fastened by one of its ends to the structure of
framework, there are two independent hydraulic pumps activated by a couple of pedals
that are positioned beneath one of the short sides, at the centre and on the bottom,
on the same side where there is a grip handle.
[0011] This grip handle consists of a chrome plated iron bar which is used to steer the
cart, which is fitted with two pairs of rubber wheels with bearings. The front wheels
are fixed, whereas the rear wheels turn 360° and are equipped with a hand brake.
[0012] On the top of the invention, and over the support surface, there is a stainless steel
tray that slides along the surface thanks to the lower bearings with which it is fitted,
receiving or ejecting one end of the coffin with the least possible effort.
[0013] On the end of the invention that is opposite the end with the grip handle, there
is a retractable bracket that prevents the coffin from moving once it is positioned,
consisting of a metal bar with holes that can be adjusted to handle any size of coffin.
[0014] The invention has two drapes at the sides to hide all the interior mechanism, so
that the hand-driven cart has a suitable appearance.
DESCRIPTION OF THE DRAWINGS
[0015] To complete this description, and in order to provide a better understanding of the
characteristics of the invention, this specification contains two sheets of drawings,
to illustrate the invention, but which do not limit it in any way, showing the following:
Figure number 1 represents a perspective view of the object of the invention, relating
to an improved hand-driven cart to transport coffins, in which the coffin support
surface is raised and therefore affords a view of the interior mechanism.
Figure number 2 represents a side view of the object represented in figure number
1.
Figure number 3 represents an aerial view of the object shown in the previous figures.
Figure number 4 represents a view of the object shown in the previous figures from
one of the short sides.
PREFERRED EMBODIMENT OF THE INVENTION
[0016] These figures show how the improved hand-driven cart (1) to transport coffins is
based on a metal structure or frame (2), which has two pairs of wheels on the bottom,
one of which pairs of wheels (3) is mobile and turns freely up to 360° and acts as
steering wheels, and the other of which pairs of wheels (3') is fixed.
[0017] The invention has two drapes (4) on the sides in order to keep the internal mechanism
out of sight.
[0018] Inside, there are two pairs of parts positioned diagonally (5) and (5') and also
(6) and (6'), joined by transversal parts (7) and (7'), in the centre of which there
are two pairs of metal strips (23) and (23'), which are fastened to the upper ends
of two pumps (10) and (10'), which are independent hydraulic pumps that are activated
independently by two pedals, each of which activates each of the hydraulic pumps (10)
and (10'), allowing for pumping and purging the hydraulic oil that will generate the
raising and lowering movement of the coffin supported by the upper surface of the
support platform (13).
[0019] The two pairs of metal strips identified above as (5), (5'), (6) and (6') are in
turn fastened to two pairs of diagonal parts (8) and (8') and (9) and (9'), one of
the ends of which is joined to the structure (2) and the opposite end of which is
joined to the lower ends of the support surface (13), constituting said parts the
surface (13) support, raising and lowering mechanism, and the diagonally positioned
parts (8), (8'), (9) and (9') attached to the structure or chassis (2) move about
inside by means of two pairs of guides (12) and (12') positioned one in front of the
other coinciding with the area where these parts are fitted, so that, depending on
the rising and lowering movements generated by the pumps (10) and (10'), these parts
make the surface (13) move likewise.
[0020] Obviously, the pedals (11) and (11') are connected to the pumps by means of hoses
(21) and (21'), as can be seen on figure number 2.
[0021] Continuing with figure number 1, on the top there is a tray (14) that slides along
the surface (13) by means of bearings, in order to receive the coffin, for which two
stops (15) and (15') are fitted, which, when they slide from one end to the other
when a coffin is in place, act as stops when the bearings beneath the mobile tray
(14) are forced to stop when they reach the area that coincides with the grip handle
(17), which is telescopic, and therefore increases the support surface (13) and the
mechanism consisting of the tubular part (20) in which a part (16) with its corresponding
clamping member (18) is inserted forming a 90° angle to immobilise this sliding part
(16) when the coffin has been placed on the surface (13).
[0022] The end of the surface (13) that is opposite the end with the grip handle (17) is
equipped with a sliding cylinder (19) that collaborates with the movement of the coffin.
[0023] The invention works by aligning the surface (13) on the same plane on which the coffin
to be transported is positioned, and applying the brake mechanism (22) to the rear
wheels (3).
[0024] One of the ends of the coffin (neither represented nor referenced) is placed on the
upper tray (14) resting on the stops (15) and (15') and the coffin is then slid until
the tray (14) reaches the stop located near the grip handle (17).
[0025] The safety brake consisting of the bracket (16) is now applied, and the surface is
raised and retains the coffin at the end opposite the end first positioned on the
platform (13) in collaboration with the tray (14).
[0026] The brakes (22) are then removed from the rear wheels (3) and the coffin is transported
to the desired place, where operations proceed in reverse and, if necessary, by using
the brakes (11) and (11'), at the optimal inclination generated by the pedals on the
hydraulic pumps (10) and (10') independently.
