Description
BACKGROUND OF THE INVENTION
[0001] This device is directed to a 2 in one Broom Set. wherein a
standard house broom can be joined with a push broom.
[0002] The art indicates that there are a number of patents which
are similar in design or utility to the present invention. None of
the aforesaid patents, however, militate against the unique
structure defined by this invention.
[0003] As described below in brief ,are examples of somer of the
most pertinent inventions.
[0004] U.S. Pat. No. 3,073,603 is directed to a size adjustable
rake, wherein the rake can be adjusted as to its overall width and
the number of rake fingers carried by the rake. The gardener can
use the rake at its maximum size with a minimum number of fingers
for raking leaves from the lawn, while areas having limited access
to be raked such as between flowers in a flower bed can be handled
by easily adjusting the rake to its smaller size with a minimum
number of fingers.
[0005] U.S. Pat. No. 3,855,766 teaches a controllable broom rake
convertible from a relatively wide lawn type rake to a relatively
narrow type rake. This rake has a center section and two foldable
end sections hinged to opposite ends and selectively movable
between an open position extending contimuously from the center to
provide a wide raking span and a closed position folded rearwardly
over the center section to provide a narrow raking span.
[0006] U.S. Pat. No. 4,244,168 pertains to a broom rake useful
outdoors for sweeping debris and raking leaves off a smooth hard
surface such as sidewalks or a discontinuous surface such as
gravel. The device has a base, a handle attached to the base from
which bristles extend. Each bristle has a first portion attached to
the base and a second portion at an angle to the first portion. By
making the bend angle betweeen 100 and 150 degrees, the implement
operates as a broom when pushed away from the user and as a rake
when pulled toward the user.
[0007] U.S. Pat. No. 6,032,447 describes a gardening tool that
includes a detachable broom head that can easily be removed from a
garden rake on which it is mounted. A gardener can use a single
tool for both raking and brooming. The detachable broom head makes
it possible to switch from raking to brooming by merely rotating
the rake side The broom head is attached to the upper face of the
rake frame so that a dual purpose lawn and garden tool is created.
Flipping the tool over so that the broom bristles face the ground,
the tool becomes a broom. When no longer needed the broom can be
detached and stored. There are several embodiments for attachement
including a pair of flexible clips that grip the rake frame. The
profile of the broom head is contoured to assist in engaging the
frame.
[0008] U.S. Pat. No. 6,134,739 is cited to show a push broom handle
brace similar to that used in the invention wherein the brace
includes two integral angular legs each leg having a bottom end
with an aperture through which a fastener is used to fasten the
brace to the base of a broom. Coincident with the spaced apart legs
is a horizontal section having in its medial region an arcuate
section with two vertical legs. The arc embraces and secures the
handle by passing a bolt through the two extending legs.
[0009] While the references cited do show tools that lend
themselves to expansion and adjustment as well as a brace for
securing a handle to a broom, the designs are structurally
different from those of applicant's two in one broom. Furthermore
for the most part the function of these tools is generally
different. Outside of '739 the cited implements are used outdoors
on lawns and sidewalks, whereas applicant's broom is intended to be
used in the household. Of course if desired, this broom could
readily be used on sidewalks and the like.
[0010] It is therefore an object of this invention to make a broom
which combines the features of an ordinary house broom with that of
a push broom.
[0011] It is also an object of this invention to make the so called
two in one broom readily detachable so that for small jobs the
house broom could be used per se.
[0012] It is a further object of this invention to make the handle
of the broom angularly adjustable with respect to a vertical plane
that intersects the transverse position of the broom head.
[0013] It is finally an object of this invention to use a brace to
provide a strong support for combining the elements of a push broom
and a house broom compactly.
SUMMARY OF THE INVENTION
[0014] This invention is directed to a convertible broom wherein
the standard house broom is enlarged to be used as a push broom.
Several embodiments can be used to achieve this objective. In one
embodiment the standard broom is joined by fitting this broom into
a U-shaped base with broom into respective interlocked mating
surfaces. A second embodiment includes a broom head having
identical right handed and left handed members wherein the standard
broom is aligned with the two members and inserted therebetween.
The two members are then pressed together whereupon a latch secures
the three units together. A third embodiment has the two heads
hinged at one end. the standard is aligned with the two members
which are then swung together and latched as in the second
embodiment. A fourth embodiment uses a rectangular slot in the push
broom, wherein the standard broom is inserted upwardly through the
slot and connected to the push broom. To make a secure connection
between the two brooms a brace is fastened to the base of the push
broom. The broom handle is secured to a seat of the brace.
Additionally the broom handle is secured to the standard broom in
such a manner that it can be adjusted for use at different
angles.

DETAILED DESCRIPTION OF THE INVENTION
[0023] FIG. 1 shows a standard broom 1 that comprises a broom head
2 rectangular in shape and containing a conventional number of
bristles 3. In the center of the head is a cylinder 4, oriented in
a north south direction and pivotally mounted on a rod 5 that runs
in an east to west direction through respective apertures 6 in the
cylinder and spaced semicircular members 7, each adjacent the
cylinder. Adhesively secured to at least one of the members 7 is a
scale 8 marked in degrees from 0 to 180. A pointer 9 with a ring 10
fits tightly around the rod, and a butterfly nut 11 threadably
engages the rod at the end adjacent the scale, whereas the other
end of the rod that passes through the semicircular member is
rotatably secured with a cap 12. A handle 13 is screwed into the
top of the cylinder so that when the rod is pivoted by turning the
screw. the desired angulation of the handle can be attained. The
angulation can be maintained by turning the screw on the rod until
it presses tightly on the semicircular member.Turning the screw
counterclockwise on the rod enables readjustment of the angle of
the broom handle. The standard broom described above can be
converted into a push broom by combining the broom head 2 with
another broom head 14. The attachment can be done in a number of
ways. In FIG. 2 head 2 is combined with a broom head 14 by using
interlocking mating surfaces of angles 14a and 14b. Broom head 14
is a U-shaped member having a plurality of bristles around the
periphery of the U. Broom head 2 with surfaces 14a locks with 14b
of head 10 wherein the horizontal legs of the angles of broom head
14 will overlap the horizontal legs of the angles of head 2. A
slight modification is shown in FIG. 2a wherein horizontal legs of
the angles of broom head 2 overlap horizontal legs of the angles of
broom head 14. To support the broom head 2 in broom head 14 a brace
15 is used. Brace 15 comprises two inclined legs 16 with flanged,
ends 17 that form an oblique angle with the legs. Each of these
ends have slotted apertures 18 and fasteners 19 for securing the
flanged ends of the legs to broom head 14. The legs are joined by
an arc 20 located in the medial region between the legs. The arc is
fashioned to have a circumferential length of 340 degrees with two
parallel legs 22 extending downwardly from the respective ends of
the arc.The handle is inserted in the arc. Legs 22 have apertures
21 secured by a bolt 23 and nut 24 whereby the broom handle is
tightened in the arc. The apertures in the flanged ends 17 are
slotted so that the legs can be shifted in accordance with the
desired angular position of the handle. In FIG. 3 is a second
embodiment wherein the second broom head 10a is made in two
identical halves, each half having a U shaped slot. Broom head 2 is
aligned with the respective broom heads 10a whereupon the heads 10a
are pressed together over broom head two and latched together with
catch 26. FIG. 4 shows a third embodiment wherein two broom heads
10b identical in shape to the broom head of FIG. 2 are joined at
one end by a hinge 27. Broom head 2 is inserted into one of the two
broom heads 10b and the other broom head half is swung around so as
to enclose broom head 2. It is to be understood that the broom
heads 10b are each half the width of the broomhead 14 shown in FIG.
2. The latch is the same as in FIG. 3 except that it is located at
one end of a broom head and its connector is different. The brace
described above is also useed in the embodiments of FIGS. 3 and 4.
FIG. 4a illustrates the fourth embodiment, wherein rectangular push
broom head 34 is shown with a centrally located slot 35. Sweep
broom head 2 with all the accessories such as the cylinder,
semicircular members, rod and handle are inserted upward through
the slot. The handle is then screwed into the cylinder and
connected to the brace as explained above. FIG. 5 shows an enlarged
view of the latch 26, used in FIG. 3 which comprises a hooked
member 30, pivotally mounted on rod 29 with head 29a and threadably
fastened close to the ends of one U shaped member 10a. 26 is
connected to a stud 28 fixed on a correesponding position to the
other identical U shaped member 10a when the members 10a are
pressed together around broom 2. In FIG. 4 only one latch 26 is
used to connect the two U shaped members 10b. FIG. 6 shows latch 26
attached at the end of U shaped member 10b opposite the side where
the hinge 27 is connected. On the other U shaped member 10b a ring
shaped connector 3 lends in a rod 32 which is threaded into the
other member 10b The ring is so positioned that when the two U
shaped members 10b are pressed together over broom 2, latch 26 will
engage the connector 31.
[0024] Several embodiments of the invention have been described and
illustrated, but it should be understood that it would be obvious
to one skilled in the art that various modifications and changes
could be without departing from the invention as defined by the
appended claims.
