A system for remotely opening a door on a canvas car shelter
FIELD OF THE INVENTION
[001] The present invention relates generally to temporary shelter structures,
but more particularly to a device for remotely opening a door on a canvas
car shelter.
BACKGROUND OF THE INVENTION
[002] Garage tents or shelter are generally used in areas where snow is
abundant and the driveway is often converted into a garage for the
winter months. This eliminates the need for users to shovel their
driveway. As well as protects their cars from snow, sleet and wind.
These shelters are available in a variety of sizes and shapes that
provides protection of one or more vehicles.
[003] The doors of these shelters are made of the same material as the rest of
the shelter and must be manually opened and closed, which can be a
laborious process, which results in the flap door remaining open and
snow, sleet, and ice enters into the shelter, which defeats its purpose.
There is therefore a need for a better method of opening and closing
these doors canvas car garage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] A system for remotely opening a flap door (25) on a canvas car shelter
(24) comprises a remotely actuated motor (103) provided with a double
pulley member (20) attached to a pair of support members (32) onto a
rib frame (16), forming part of the shelter (24). The rib frame (16) as well
as canvas (34) are well known in the art of car shelters (24).
[0024] The remotely actuated motor (103) wraps or unwraps at least one wire
(30) around a double pulley member (20). The wire member (30) goes
into two direction, passes through a pair of frame pulleys (35)
attached to the rib frame (16), and down through a second set of pulleys
(37) attached proximal to a pair of slide support members (105) located
on either side of the flap door (25), and up so that its two ends are

CA 02840930 2014-01-29
7
fixedly attached to the rib frame (16). These slide support members
(105) slide around a pair of internal support rods (106) and are
connected to the lower horizontal rod (104) onto which the flap door (25)
is attached. The advantage of using a second set of pulleys (37) is that
the length of the pull by the wire (30) is cut in half. But the set second
set of pulleys (37) could be eliminated and the ends of the wire member
(30) could connect directly to the pair of slide supports (105). Also, a
pair of wire members could easily substitute for the single wire member
(30) while keeping the same operating principle.
10[0025] When the remotely actuated motor (103) is activated, the wire member
(30) raises the pair of slide brackets (105) along inner rods (106). The
inner rods (106) have the flap door (24), attached to it by way of clip
members (29). The inner rods (106) have their lower ends attached to
an adjustable bracket (109) which is itself attached to a base member
(111) forming part of the rib frame (16). The inner rods (106) have their
upper ends attached to the upper part of the rib frame (16) by way of
attachment brackets (11). The flap door (24) rises vertically and folds as
it does.
[0026] Reversing the operation obviously results in the lowering of the flap
door
(24). The remote control unit (not shown) and all associated electronics
(not shown) are well known in the art and need not be discussed herein.

CA 02840930 2014-01-29

[0027] As to a further discussion of the manner of usage and operation of the
present invention, the same should be apparent from the above
description. Accordingly, no further discussion relating to the manner of
usage and operation will be provided.
5[0028] With respect to the above description then, it is to be realized that
the
optimum dimensional relationships for the parts of the invention, to
include variations in size, materials, shape, form, function and manner of
operation, assembly and use, are deemed readily apparent and obvious
to one skilled in the art, and all equivalent relationships to those
illustrated in the drawings and described in the specification are
intended to be encompassed by the present invention.
[0029] Therefore, the foregoing is considered as illustrative only of the
principles of the invention. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not desired to
limit the invention to the exact construction and operation shown and
described, and accordingly, all suitable modifications and equivalents
may be resorted to, falling within the scope of the invention.
