REFLECTOR FOR MARKING DRIVEWAYS AND THE LIKE
Abstract
The reflector for marking driveways and the like is adapted to
be resiliently clamped to a rod which can be inserted into the
ground. One or more reflectors can be supported on the rod at
various angles and reflect the lights of passing cars to mark, for
example, the entrance to a driveway. Each reflector is constructed
of a circular molded plastic frame to hold the reflecting plastic
and has internal resilient members projecting inwardly from the
frame which cooperate to securely clamp the reflector to the
supporting rod which passes through aligned holes in the frame and
a passage between the springlike internal members. Each reflector
at one end has an octagonally shaped embossment on the frame around
one of the holes in the frame, and a second embossment around the
aligned hole at the opposite side of the frame which has an
octagonally shaped inset. Thus, the embossment of one reflector can
be seated in the inset embossment of an adjacent reflector to
locate a respective reflector at four different angular positions
on the supporting rod relative to an adjacent reflector.

marking driveways and the like, which comprises a frame for receipt
of reflecting means, a pair of internal resilient clamping members
extending inwardly from the frame toward each other in cooperating
relationship to a position directly opposed with respect to each
other to provide a passage therebetween, aligned apertures at
opposite ends of the frame and in line with said passage to adapt
the reflector for receipt of a standard passing through the aligned
apertures and passage, and with the resilient clamping members
disposed to securely clamp the reflector to the standard with which
it is assembled but permitting ready manual movement of the
reflector to varying positions on said standard.

Description
BACKGROUND OF THE INVENTION
Reflectors supported on standards or rods which may be inserted
into the ground to mark the entrance or edges of the driveway are
well known. However, heretofore the reflectors have been held onto
the standard or rod by fasteners, such as external clamps, which
had to be released before the reflectors could be moved up or down
on the rod. Furthermore, the reflectors needed to be completely
removed from the rod before they could be changed to different
angular positions. The constructions described are expensive and do
not have the desired versatility for use under varying
circumstances.
SUMMARY OF THE INVENTION
The present invention overcomes the deficiencies of the prior
reflector markers by supplying a reflector which is easily
assembled on the rod and requires no removable fastening members to
hold it in the position described on the standard or supporting
rod.
The reflectors of the invention preferably are assembled on a round
standard or rod for ease of rotation of the reflectors held by the
rod to the angular position desired without removal of the
reflectors from the rod.
The reflectors may be made in several different ways. Each
reflector normally has a circular frame which is preferably molded
from plastic and provided internally with annular seats on opposite
sides to receive and retain colored reflecting members on both
sides of the frame Under one embodiment of the invention, a pair of
resilient armlike members are secured at one end to the inside of
the circular frame and then curve inwardly toward each other with
the inner end of one of the armlike members being free and located
opposite the free end of the other armlike member. The armlike
clamping members extend for a short distance in a parallel plane in
cooperation with each other to provide a passage therebetween which
is aligned with apparatus or holes provided on opposite sides of
the frame. The passage between the armlike members is slightly less
in cross section than the supporting rod to which the reflector is
adapted to be applied by passing the rod through the aligned holes
in the frame and the passage between the armlike members. Due to
their resilience, the armlike members are compressed outwardly
toward the frame by the insertion of the rod in the passage between
them and consequently securely clamp the rod to the frame at the
position desired. Although the reflectors are securely held in
place, they are easily moved up and down on the rod or rotated to
different positions and readily stacked one upon the other.
Under another embodiment of the invention, an additional clamping
of the rod by the armlike members is accomplished by permitting the
free ends to move slightly before engaging an abutment molded to
the inside of the frame which changes the rotational movement of
the arms to a straight line movement whereby further compression of
the armlike members occurs.
Even a greater clamping of the armlike members of the reflector can
be accomplished by securing both ends of the armlike members to the
frame so that they extend toward each other in a semi-circular
complementary manner. In this case, since neither end is free to
move, the body or central portions of the armlike members are
compressed upon insertion of the rod between them to securely clamp
each reflector to the rod.
In all of the described embodiments, an octagonal shaped embossment
is provided around one of the rod-receiving holes in the frame. A
second embossment having an octagonal shaped insert is secured to
the frame around the opposite rod-receiving hole in the frame. With
this construction, when the reflectors are stacked on a rod, the
octagonal shaped embossment of one reflector rests in the octagonal
insert embossment of the next adjacent reflector. The construction
permits one reflector to be securely held at four different angular
positions with respect to an adjacent reflector.
DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a side elevational view with parts broken away and
illustrating one embodiment of reflectors stacked on top of the
other on a supporting standard;
FIG. 2 is a section taken on line 21'2 of FIG. 1;
FIG. 3 is a section taken on line 3--3 of FIG. 1 and illustrating
in phantom the various angular positions in which a reflector may
be located on a standard;
FIG. 4 is a perspective view illustrating a second embodiment of
the invention; and
FIG. 5 is a perspective view of another embodiment of the
invention.
Referring to FIGS. 1-3 of the drawings, there is illustrated three
reflectors 1 assembled on the standard 2 which is shown as a rod
which at one end is adapted to be inserted in the ground for
marking a driveway or the like and which at the other end is
provided with cap 3. The reflectors 1 are shown as stacked one on
top of the other with the upper two reflectors facing in the same
direction but with the lowermost reflector turned at an angle of
90.degree. with respect to the upper two reflectors.
The reflectors 1 shown in FIGS. 1-3 have a circular frame 4 which
may be molded from plastic and the frame 4 internally on both sides
is inset to provide the annular seats 5 for receipt of the colored
reflecting members 6 which reflect light the color of the
reflecting members. Reflecting members 6 are preferably of a
specially designed plastic material and are force fitted onto seats
5 and may be cemented or otherwise secured into place.
In the embodiment of the invention in FIGS. 1-3, frame 4 is
provided with the resilient, springlike, compressible arms 7 which
extend inwardly of frame 4 toward each other. The arms 7 are
secured to the inside of frame 4 at one end at opposite sides of
the frame and extend inwardly toward each other in a semi-circular
manner to a position relative to each other whereby they extend in
a parallel plane for a short distance and cooperate to provide a
passage 8 between them of a lesser cross section than rod 2. The
inner ends of the complementary extending arms 7 are free and
located opposite each other and curve outwardly toward the frame 4.
The rod 2 is assembled with each reflector 1 by insertion through
the aligned apertures or holes 9 in opposite sides of the frame 4
and the passage 8. The insertion of rod 2 between the arms 7
compresses arms 7 outwardly toward the frame 4 due to the greater
cross section of the rod to effect a secure clamping by arms 7 of
reflector 1 to rod 2.
However, reflectors 1 are readily moved up and down rod 2 to
different positions and can be readily applied to or removed from
standard 2. When standard 2 is a round rod, the reflectors 1 are
also readily rotated to different positions.
In order to locate one reflector 1 in a fixed location with respect
to an adjacent reflector 1, each reflector is provided with an
embossment 10 around one of the holes 9 and preferably, the
embossment 10 on the outside, is of octagonal shape. A second
embossment 11 is provided around the opposite hole 9 and this
embossment is of larger size and has an inset 12 preferably of
octagonal shape and of a size to receive an embossment 10 of an
adjacent reflector 1. Once the embossment 10 is seated in inset 12
of embossment 11, the reflectors 1 are fixed relative to each other
at the angle selected. If the embossments 10 and 11 have the
octagonal shaped described, a reflector 1 may be set in four
different angular positions relative to an adjacent reflector 1.
The securing of the reflectors together, as described, permits easy
separation to change the angle of one with respect to the other and
permits simultaneous rotation of several reflectors which are
secured together. FIG. 3 illustrates in full lines the angular
position of the lowermost reflector 1 with respect to the middle
reflector 1, and in phantom lines there is shown the various
angular positions to which the lowermost reflector 1 in FIG. 1 may
be moved.
A second embodiment of the invention is illustrated in FIG. 4. In
that embodiment, the frame 4 of the reflector 1 is provided with
the aligned apertures or holes 9 at opposite sides of the frame 4
and with the embossments 10 and 11, previously described, around
the holes 9 on the outside of the frame to stack one reflector on
top of the other and secure them together. The semi-circular arms
13 are secured internally of frame 4 on opposite sides of the frame
and extend toward each other and in a parallel plane for a short
distance to provide the passage 14 therebetween and aligned with
holes 9 for receipt of the standard 2 when it is inserted through
the aligned holes 9. Arms 13 have free ends 15 which curve
outwardly toward the frame 4. In addition, the L-shaped abutments
16 are secured to the inside of frame 4 with the bottom of the L of
each abutment terminating a short distance from the free end of
each arm 13. The free end 15 of each arm 13 is free to move in a
semi-circular path or a short distance under compression upon
insertion of standard 2 but upon engagement with a respective
abutment 16, the free end 15 of each arm 13 tends to move in a
straight line. Consequently, the body portion of each arm 13
engaging standard 12 is compressed toward frame 4 by standard 2 and
clamps the reflector 1 to standard 2 with even greater pressure
than do the arms 7 of the first embodiment.
In the event the frame 4 is molded, the L-shaped abutments 16 are
offset to the outside of the frame under the molding procedure. In
such event, the enlarged ledge 17 is provided on the inner leg of
each abutment and extends inwardly so that it will be engaged by
the free end 15 of a respective arm 13 when the arm 13 is
compressed by insertion of standard 2 in the reflector.
Another embodiment of the invention illustrated in FIG. 5 effects
even a greater clamping force by the arms of the reflector 1 on the
standard 2.
This embodiment, the same as the embodiments described, has the
aligned apertures or holes 9 at opposite sides of the frame 4 and
the embossments 10 and 11 which are provided on the outside of
frame 4 around holes 9 in order to secure one reflector 1 to
another in stacked relation on standard 2. In this embodiment, the
semi-circular internally extending arms 18 have both ends secured
to the inside of frame 4. The arms 18 are formed complementary to
each other and the body portions of the arms 18 extend in parallel
planes for a short distance and provide a passage 19 therebetween
of lesser cross section than standard 2 which is aligned with holes
9 for receipt of standard 2. Because the ends of arms 18 are not
free to move, when standard 2 is inserted in passage 19 the body
portions of arms 18 are compressed by standard 2 to tightly clamp
the reflector 1 to the standard and yet leaving it free for
movement up and down standard 2 or rotation on standard 2 to
different angular positions.
The invention provides reflectors for ready assembly on a standard
or rod to provide a driveway guide or marker in that the reflectors
are secured to a standard by resilient arms which permit ready up
and down movement and rotation of the reflectors to the positions
desired. Simplified securing of reflectors together on a standard
are provided by mating embossments of octagonal shape on the frame
of each reflector to hold the reflectors in angular relationship to
each other.
The reflectors are preferably circular and made of molded plastic
but may be of other shapes and of other material. Likewise,
although the embossments described for securing the reflectors
together are of octagonal shaping to obtain maximum versatility,
they may be of other shapes. The driveway guide may be used as a
marker in many different locations.
Various modes of carrying out the invention are contemplated as
being within the scope of the following claims particularly
pointing out and distinctly claming the subject matter which is
regarded as the invention.
