The present invention relates to wedge assemblies which are used
to reduce vehicle user squeak and rattle complaints due to door and door latching
Vehicle doors are conventionally pivotally mounted to a vehicle frame
and latched closed. During operation, the doors may rattle and the generated stress
tends to cause sheet metal fatigue at the hinge and latch locations. Cracking and
stress marks may result with the likelihood of corrosion increasing. Wedge assemblies
are intended to prevent door vibrations and to thereby protect the hinge and latch
mechanisms from deterioration.
Wedge assemblies are subject to manipulation by the installer and
are occasionally damaged prior to installation. It is accordingly an object of
the present invention to provide a wedge assembly which is designed to prevent
damage prior to installation.
Other objects and advantages of the present invention will become
apparent from the following portion of this specification and from the accompanying
drawing which illustrates in accordance with the mandate of the patent statutes
a presently preferred embodiment incorporating the principles of the invention.
REFERRING TO THE DRAWING:
- Figure 1 is to top view of a wedge assembly made in accordance with the teachings
of the present invention;
- Figure 2 is a view of the wedge assembly taken along lines 2-2 of figure 1;
- Figure 3 is a view of the wedge assembly taken along lines 3-3 of figure 1.
The wedge assembly has a base plate 10 which has a pair of holes
12 permitting connection by bolts or the like to the door of a vehicle. The base
plate 10 supports a movable slide element 14 which is slideable along a pair of
spaced parallel and inclined cam surfaces 16 defined on the base plate. The slide
element is pulled toward its start position, at the left end of the cam surfaces
in figure 2 by a spring element 18 and can be forced down the cam surfaces against
the action of the spring by the vehicle surface which it strikes when the door
The slide element 14 is generally U-shaped (upside down) with the
bottom surfaces 20 comprising the cam followers. Elongated slots 22 are defined
in the base plate 10 in which stop elements 24 are located. These stop elements
extend downwardly from flanges 26 that extend horizontally outwardly from the
U-shaped body and are displaceable within the slots 22. The flanges 26 are trapped
by overlying inwardly extending base plate flanges 28. Movement of the wedge element
to the left (to the start position) is stopped by engagement of the rear vertical
surfaces 30 of the wedge element with inwardly extending base plate projectories
32 and forward movement is limited by the engagement of each stop 24 with the portion
34 of the base plate at the forward end of its slot 22.
To permit assembly, the overlying flanges 28 terminate short of the
forward of the forward end of the slots and are beveled 36 inwardly along the lower
front edge. As shown in figure 3, the slide element can be pivoted into its trapped
operating location (the front portion of the overlying flanges 28 will be slightly
As can be seen from figure 2, the ends of the spring are captured
by J-shaped catches 40 which open in the direction opposite to the removal direction
for the ends of the spring. These J-shaped hooks or catches minimize the likelihood
that the spring can come off a result of snapping the wedge element.
- 1. A wedge assembly comprising:
a base plate to be secured to the frame of a door including;
a pair of spaced parallel cam surfaces,
a pair of spaced parallel slots situated outwardly of said cam surfaces, defined
in a base portion of said base plate, and
a pair of capturing flanges overlying said spaced parallel slots,
a slide element to be displaced from a free state location to an advanced location
a pair of spaced parallel cam follower surfaces for engaging with the said cam
a pair of flanges, to be captured below said capturing flanges
stop means projecting downwardly from said slide element flanges for location within
said slots, said slots being selectively sized so that the displacement of said
slide element towards said advanced location will be stopped by engagement of
said stop means and the adjacent end of said slots, and
spring means interconnecting said base plate and said slide element.
- 2. A wedge assembly according to claim 1, wherein the ends of said base plate
flanges proximate the engaged ends of the the slots terminated rearward therefrom
to permit assembly of the wedge assembly.
- 3. A wedge assembly according to claim 2 wherein the lower front edges of said
base plate flange ends are beveled to facilitate assembly.
