REMORQUE ORIENTABLE

English Abstract

A steerable trailer assembly allowing the directional movement of
wheels.

Claims

CLAIM(S):
The embodiments of the invention for which an exclusive property or
privilege is claimed, are defined as follows:
1. A steerable trailer assembly, which includes the directional wheels, on
which is mounted the towing hitches to the structure frame and to a tow bar,
a cable connected to electric motor passing along said tow bar and of said
structure frame, and a wheel support is engaged to said structure frame in
front of said trailer. An elongated rod is provided of fastenings means
allowing to connect the cambers angle which are mounted to each said
directional wheel and connected to a central part member by the use of a
smaller connecting rod, and which the casters are connected between said
cambers angle and said directional wheels. A chock absorber is connected at
one end of said rod by the use of bolts and nuts, or other conventional
fastenings means to said central part member, which prevents the vibration
movement of said rod connected to said cambers angle. The parts members
are mounted to said central part member by the use of connecting rods
allowing swivelling movement of said parts members, which the plates and
said parts members are connected together by the use of bolts and nuts or
other conventional fastenings means, which maintain the center portion of
leaf springs suspension assembly, and which are provided with fastenings
means engaged to said structure frame.
2. The electric motor of the claim 1 activates the longer parts member
allowing to make turn said directional wheels, and by which the smaller parts
members join said longer parts members to said electric motor.

Steerable trailer assembly
BACKGROUND OF THE INVENTION:
Field of the invention:
The present invention relates to a steerable trailer assembly allowing
the directional movement of wheels.
Description of the retated art:
A search of prior art records has unveiled the following patents:
1. CA 1,289,986 issued in 1991 to Winkler;
2. CA 384,283 issued in 1984 to Mergen;
3. CA 2,152,245 enregistered in 1995 to Chagnon; and
4. US 4,955,630 issued in 1990 to Ogren.
The patents mentioned above are probably the most relevant. As can be
seen, the patents differ from my application and do not show a steerable
trailer assembly allowing the directional movement Qf wheels.
It is well known to used a hitch assembly for coupling a trailer to a tow
vehicle, but any system adapted to a trailer sold at the present on the market
allows the directional movement of wheels.
Summary of the invention:
The gist of the invention is therefore to provide a trailer with a system
allowing the directional movement of wheels.
In accordance with the teachings of the present invention, there is
disclosed a trailer including the directional wheels, on which is mounted the
towing hitches to the structure frame and to a tow bar, a cable connected to
electric motor passing along tow bar and of the structure frame, and a wheel
support is engaged to the structure frame in front of trailer.

An elongated rod is provided of fastenings means allowing to connect
the cambers angle which are mounted to each directional wheel and
connected to a central part member by the use of a smaller connecting rod,
and which the casters are connected between the cambers angle and wheels.
A chock absorber is connected at one end of the rod by the use of bolts
and nuts, or other conventional fastenings means to the central part member,
which prevents the vibration movement of the rod connected to cambers
angle.
The electric motor activates the longer parts members allowing to
make turn the directional wheels, and which the smaller parts members join
the longer parts members to electric motor.
The parts members are mounted to the central part member by the use
of connecting rods allowing swivelling movement of parts members, which
the plates and parts members are connected together by the use of bolts and
nuts or other conventional fastenings means, which maintain the center
portion of leaf springs suspension assembly, and which are provided with
fastenings means engaged to the structure frame .

Detailed descriution of the invention:
With reference to figs. 1 to 9, there is illustrated a trailer {A) including
the directional wheels (9), on which is mounted the towing hitches (1) to the
structure frame and to a tow bar (19), a cable (2) connected to electric motor
(16} passing along tow bar (I9) and of the structure frame; and a wheel
support (3) is engaged to the structure frame in front of trailer (A).
An elongated rod (4) is provided of fastenings means allowing to
connect the cambers angle (6) which are mounted to each directional wheel
{9} and connected to a central part member (10) by the use of a smaller
connecting rod (8), and which the casters ('1) are connected between the
cambers angle (6) and wheels {9).
A chock absorber (5) is connected at one end of the rod (4) by the use
of bolts and nuts, or other conventional fastenings means to the central part
member (10), which prevents the vibration movement of the rod (4)
connected to cambers angle (6}.
1'he electric motor (1f>} activates the longer parts member {11)(12)
allowing to make turn the directional wheels (9), and which the smaller parts
members (17)(18) join the longer parts members (11}(12) to electric motor
(1G).
The parts members (15) are mounted to the central part member (I0)
by the use of connecting rods (20) allowing swivelling movement of parts

members (15), which the plates (14) and parts members (15) are connected
together by the use of bolts and nuts or other conventional fastenings means,
which maintain the center portion of leaf springs (13) suspension assembly,
and which are provided with fastenings means engaged to the structure
frame.
Although only a single embodiment of the present invention has been
described and illustrated, the present invention is not limited to the
features of
this embodiment, but includes ail variations and modifications within the
scope of claims.
