A wall-mounted backup indicator for vehicle is mounted on a wall surface, or
appropriate fixed surface which makes the device operable, the device being
near an access door to which a van or truck needs to backup to. A signaling
alerts the driver when it is time to stop.
1. A wall-mounted backup indicator comprising:
in cooperation; a wall plate, a frame extending therefrom, an abutting arm
attached to said frame by way of a pivot;
a switch to switch on or off a a signaling means, a biasing means to bias said
arm in an outward configuration;
said wall-mounted backup indicator normally situated on the lateral side of a
dock door with said abutting arm in an outward configuration;
said abutting arm assuming an inward position when pushed by a backing vehicle
which releases said switch so that it brings power to thebiasing means.
2. A wall-mounted backup indicator having ther following method of operation:
as a truck is backing up, it intercepts an abutting arm which moves from its
outward configuration to an inward configuration which releases a switch, said
providing electrical contact between a power source and a signaling means,
signaling means thus turned on, alerts the driver of said truck;
when said truck leaves, a biasing means returns said abutting arm back to its
configuration which depresses said normally open switch which cuts off power
signaling means, which turns it off.
3. A wall-mounted backup indicator as in claim 1 wherein:
said signaling means is a visual cue.
4. A wall-mounted backup indicator as in claim 1 wherein:
said signaling means is a audio cue.
5. A wall-mounted backup indicator as in claim 1 wherein:
said signaling means is a combination audio and visual cue.

WALL-MOUNTED BACKUP INDICATOR FOR VEHICLE
FIELD OF THE INVENTION
The present invention relates to the general field of vehicle safety
accessories and is
particularly concerned with a wall mounted indicator warning when the distance
a vehicle and a wall is getting critically small.
BACKGROUND OF THE INVENTION
The problems associated with blind spots while moving a vehicle in reverse
been recognized. There have been repeated accidents associated with vehicles
up involving personal injury and damage to property.
While it is difficult for the drivers of any vehicles to evaluate the distance
rear of the vehicle and a rearwardly positioned obstacle, the problem is
when using long trucks, such as semi-trailers, which increases the possibility
or both the truck and the loading dock will be damaged.
Some documents found in the prior art address these types of problems. Indeed,
prior art has proposed technical aid to improve vision to the rear by short
or target detection and distance measurement devices. Some of these devices
been developed in recent years and introduced into the market. These devices
fall into three categories. The first category involves obstacle systems using
sensors, infrared light, video or laser devices. A second category includes
CA 02463535 2004-04-16
measurement systems and a third category involves ultrasound systems. Most of
so called relatively high-tech solutions, although offering many advantages,
to be costly and, hence, have not obtained commercial success.
Other types of systems using mechanical components have been proposed.
those mechanically activated devices typically include a large number of
components which are subject to mechanical breakdown. Moreover, they often
judgment and interpretation on the part of the driver. Another main drawback
with both high-tech and mechanical devices relates to the fact that they are
reliable and thus gives a false sense of security to the driver which may be
worst than having no indicator device at alf.
This inventor has proposed a low-cost, low-tech solution to this problem in
6,651,581, issued November 25, 2003 which proposed a back-up range guide for
vehicles mounted on the vehicle. However, it has proved a problem installing
convincing truck owners to install such a device on a truck. Some states have
vehicle departments which offer opposition to having certain type of
on trucks for various safety concerns.

SUMMARY OF THE INVENTION
The present invention offers a backup indicator which is mounted on a wall
any appropriate fixed surface which makes the device operable, the device
positioned near an access door to which a van or truck needs to back-up to.
more such doors in the United States than there are vans or trucks in
therefore, the market is larger and is not subject to motor vehicle department
and indeed are likely not to be the subject of any restrictions since they are
and do not present any danger to passerbys given their location which can be
from the ground that the most passerbys.
It is therefore an object of this invention to provide for a wall-mounted
for trucks and vans that allows the driver of a vehicle that is backing up
loading dock to conveniently and accurately determine, just by looking into
the rear view
mirror, the spacing between the back end of the truck and the loading dock.
It is a second object of this invention to allow continuous monitoring of the
spacing between the back end of the truck and the loading dock, in order to
risk of injury to occupants of the vehicle, standers-by or damage to the
vehicle or the
It is a final object of this invention to be fully reliable without requiring

To accomplish this, the wall-mounted backup indicator is comprised of an
usually situated on a lateral side of an access door onto which a vehicle is
backup for pickup or delivery purposes and in such a way as that the backing
intercept it. Thus, as the vehicle closes in on the loading dock, the
abuttting arm is
depressed from a first position into a second position which actuates a switch
turn lights up a light or sounds off an alarm or both, to alert the driver.
biasing means repositions the abutting arm back to its first position as the
moves away from the loading dock. Besides a visual cue such as a light, an
can be used because in broad daylight, if the sun hits the light directly, it
may be difficult
to see whether it is on or off, that is why, in the desscription, the
means" is used co encompass any suitable means, all falling within the scope
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 Front view of the wall-mounted backup indicator.
Fig. 2a Top view of the wall-mounted backup indicator switched on.
Fig. 2b Top view of the wall-mounted backup indicator switched off.
Fig. 3 Side view of the wail-mounted backup indicator.
Figs. 1-3 A wall-mounted backup indicator (10) is comprised of an abutting arm
wall plate (14) a pivot (16) supported by a frame (18) which acts as unifying
means to all
the parts, including a switch (20) a biasing means (22) which can also be
the pivot (16), and a signaling means (24) connected to a power source (not

electrical wiring (26). The biasing means (22) has one anchoring point at one
of the abutting arm (12) and the other anchoring point at the edge of the wall
FIG. 4 The wall-mounted backup indicator (10) is situated on the lateral side
of a loading
dock door (30), next to the back up pads (32) in such a way that the backing
intercept it. Thus as the vehicle closes in on the loading dock, the abuttting
arm (12) is
moved from a position such as in Fig. 2a to a position such as in Fig. 2b
pressure on the switch (20), this actually turns the switch (20) on so that
the signaling means (24) via electrical wiring (26). The driver, thus alerted,
backing up. When the truck leaves the dock, the biasing means (22) puts the
arm (12) back to the position shown in Fig. 2a.
