Abstract
A dustpan includes an open-front receptacle, at least one elongated rail on the receptacle, an elongated handle having a coupling portion, and a coupling mechanism slidably coupled to the at least one rail and pivotally coupled to the coupling portion of the handle so that the handle is both slidably and pivotally moveable relative to the receptacle between use and storage positions. A broom includes an elongated second handle and a head carrying set of bristles, the head having a housing with curved side portions shaped and dimensioned to respectively nest in recesses in the dustpan handle in a stowed condition clipped to the dustpan handle in such a way that it does not interfere with the pivoting and sliding movement of the dustpan handle. The dustpan receptacle can be stood on its flat rear end wall with the stowed broom received therein.
Description
BACKGROUND
This application relates to devices for use in cleaning floors and, specifically, to tools or utensils for sweeping. The application relates in particular to dustpan and broom combinations.
Dustpans, brooms and combinations thereof have long been provided. Indeed, it has long been known to have dustpans with long handles so that they can be operated while the user is in an upright or standing position, as well as to have arrangements wherein the handles of the broom and dustpan can be clipped together for storage. In particular, arrangements have been provided wherein the broom head and/or bristles are stored within the dustpan receptacle when not in use.
However, heretofore, such combinations have required that the handles of the dustpan and broom be separated from each other in order to withdraw the broom bristles from the dustpan receptacle. Dustpans with pivoting handles have also been provided but, heretofore, they have not been capable of pivoting movement while the broom handle is connected thereto. Also, while it is known to provide dustpans with pivoting handles which can be latched in different positions, the movement to and from a latched condition has heretofore required the use of two hands, with one had to operate the dustpan handle and another to operate a latch mechanism, for example.
SUMMARY
There is disclosed in this application a dustpan/broom combination which avoids the disadvantages of prior arrangements, while affording additional structural and operating advantages. An important aspect is the provision of a dustpan with a long pivoting handle which can be easily moved between use and storage conditions with a single hand.
Another aspect is the provision of a dustpan and broom combination, wherein the broom is connectable to the dustpan handle and is moveable therewith between the various conditions of the dustpan handle.
Another aspect of the provision of a combination of the type set forth, which is a relatively simple and economical construction.
Certain ones of these and other aspects may be attained by providing a dustpan comprising an open-front receptacle, at least one elongated rail on the receptacle, an elongated handle having a coupling portion, and coupling mechanism slidably coupled to the at least one rail and pivotally coupled to the coupling portion of the handle so that the handle is both slidably and pivotally movable relative to the receptacle.

DETAILED DESCRIPTION
Referring to
FIGS. 1-3
, there is illustrated a combination, generally designated by the numeral
10
, including a dustpan
20
and a broom
70
. Referring also to
FIGS. 6 and 8
, the dustpan
20
includes an open-front receptacle
21
including a substantially flat rear end wall
22
, integral along three sides thereof with a forwardly projecting peripheral wall structure
23
including opposed side walls
24
and
25
and a top wall
26
. The side walls
24
and
25
may diverge slightly forwardly and may be slightly convex, as viewed from the outside thereof and respectively have downwardly and forwardly sloping upper front edges
27
. The top wall
26
may also be slightly convex, as viewed from the outside, and has a concavely curved front edge
28
which is continuous with the front edges
27
of the side walls
24
and
25
and defines a cutaway arcuate front opening
29
in the top wall
26
, as can best be seen in
FIGS. 1 and 3
. The peripheral wall structure
23
also includes a generally rectangular bottom wall
30
having a flat rear portion
31
and a slightly downwardly and forwardly sloping front portion
32
terminating in a beveled lip
33
.
Referring also to
FIGS. 5 and 7
, respectively integral with the side walls
24
and
25
and projecting laterally inwardly therefrom are elongated webs
34
, which are substantially parallel to the bottom wall
30
and are integral at their inner ends with rails
35
which are generally oval in transverse cross section, the oval having a major axis substantially perpendicular to the bottom wall
31
. The lateral inner surfaces of the rail
35
are cut away to define recesses
36
spaced apart by stiffening webs
37
. Projecting laterally inwardly from the forward end of each rail of
35
is a short stop lug
38
. Integral with each sidewall
24
,
25
a short distance rearwardly of the rear end of the associate rail
35
is a mounting post
39
with narrow rectangular bosses
39
a
immediately thereabove and therebelow (one shown in FIG.
7
). Respectively integral with the side walls
24
and
25
and projecting laterally inwardly therefrom, just rearwardly of the mounting posts
39
, are retaining projections
40
, each including a narrow rectangular rib
41
integral with a downwardly-opening, general C-shaped flange
42
(see FIGS.
7
and
8
).
Respectively mounted on the mounting posts
39
are two substantially rectangular stop plates
44
, each having a circular central opening therethrough receiving the associated post
39
, being retained in place by a toothed washer
46
, such as a Tinnerman washer, which fits over the associated mounting lug
39
to firmly mount the stop plate
44
in place. The bosses
39
a
provide parallel seating surfaces for the stop plates
44
on the diverging side walls
24
,
25
. Each stop plate
44
has a laterally inwardly projecting flange
45
at a forward end thereof which is disposed in use against the rear or inner end of the associated rail
35
.
Referring also to
FIG. 4
, the dustpan
20
has a handle assembly
50
including an elongated shaft
51
provided at the distal end thereof with an overmolded grip
52
, which may be formed of a suitable elastomeric material, such as that sold under the trademark SANTOPRENE. The grip
52
is provided at its lower end with a forwardly projecting C-clip
53
. The proximal end of the shaft
51
is socketed in the neck portion of a generally y-shaped yoke
55
having a pair of legs
56
, respectively defining concave recesses
57
on the sides thereof generally facing downwardly and forwardly in use. Each leg
56
is provided at its proximal end with a retaining extension
58
provided at its end with a thickened stiffening lug
59
.
Referring in particular to
FIGS. 5 and 6
, each retaining extension
58
has formed therethrough a generally keyhole-shaped aperture
60
, including a circular portion
61
and a generally triangular tongue portion
62
. The legs
56
are disposed in use just laterally inwardly of the rails
35
, being respectively connected thereto by couplers
65
. Each coupler
65
includes a generally cylindrical shank
66
which extends through the aperture
60
in the associated leg
56
, the shank
66
being provided at its inner end with a keyhole-shaped head
67
dimensioned to fit through the aperture
60
in the associated leg
56
in one orientation. Each coupler
65
is provided at the opposite end of the shank
66
with a generally C-shaped channel
68
adapted to slidably receive the associated rail
35
therein, as can best be seen in FIG.
5
.
In assembly, the heads
67
of the couplers
65
are respectively fitted through the keyhole-shaped apertures
60
in the legs
56
from the outside to the inside, and then rotated 180 degrees, so that the tongue portions
62
extends toward the distal ends of the legs (see FIG.
6
). Then, the channels
68
are slipped over the rear ends of the rails
35
and the stop plates
44
are then mounted in place, the stop plate flanges
45
cooperating with the stop lugs
38
on the rails
35
to prevent the couplers
65
from coming off the rails
35
. Thus, the couplers
65
cooperate to form a coupling mechanism which permits sliding movement of the handle
50
along the rails
35
between a forward position against the stop lugs
38
(see
FIG. 5
) and a rearward position against the stop flanges
45
(see FIGS.
3
and
8
), while at the same time accommodating pivotal movement of the handle
50
about the axes of the coupler shanks
66
relative to the receptacle
21
. When the handle
50
is in its rearward position and in a storage condition generally parallel to the bottom wall
30
, the retaining extensions
58
of the handle legs
56
will respectively overlie the retaining projection ribs
41
, as can best be seen in
FIG. 8
, for a purpose to be explained more fully below.
When the handle
50
is slid to its forward position it can be pivoted between the storage condition and an upright use position (see FIG.
5
), wherein the longitudinal axis of the shaft
51
is disposed at a large acute angle to the bottom wall
30
. More specifically, as the handle
50
is pivoted upwardly, the distal ends of the retaining extensions
58
frictionally engage the inner surface of the bottom wall
30
, just rearwardly of the sloping front portion
32
thereof and, as pivoting movement of the handle
50
continues, the bottom wall
30
flexes slightly to allow the distal ends of the retaining extensions
58
to cam forwardly past the junction between the rear portion
31
and sloping front portion
32
of the bottom wall
30
until the handle legs
56
engage the front edge
28
of the top wall
26
in a use position, wherein the longitudinal axis of the shaft
51
is tilted just slightly rearwardly past the vertical (see FIG.
5
). Thus, the retaining extensions
58
undergo a camming, over-center movement to resiliently retain the handle
50
in its upright use condition. It will be appreciated that the arcuate front opening
29
in the top wall
26
accommodates the pivotal movement of the handle
50
.
Referring also to
FIG. 9
, the broom
70
includes a handle
71
having an elongated hollow tubular shaft
72
provided at its distal end with an overmolded grip
73
, which may be formed of SANTOPRENE and may have a hole
74
formed therethrough at the distal end thereof. The broom
70
also includes a head
75
having a generally flattened, hollow housing
74
provided with a cylindrical neck
76
and flattened, generally triangularly-shaped front and rear walls
77
and
78
, joined by arcuate, sloping sides
79
. The broom
70
includes a plastic bristle plate
80
having holes or apertures formed in the lower surface thereof for respectively receiving bunches of bristles
82
, which may be secured in place by adhesive or other suitable means. The bristle plate
80
has a neck post
83
projecting upwardly therefrom centrally thereof and is received in the lower end of the hollow handle shaft
72
, being secured in place by any suitable means. The bristle plate
80
has a snap rim
85
formed on the outer periphery thereof adapted for engagement with snap beads
84
projecting laterally inwardly from the head housing
74
adjacent to its lower end (see FIG.
3
).
In assembly, the lower end of the handle shaft
72
is fitted through the upper end of the head housing neck
76
and is secured to the neck post
83
of the bristle plate
80
. Then, the handle shaft
72
is pulled upwardly, drawing the bristle plate
80
upwardly into the lower end of the head housing
74
until the snap rim
85
snaps past the snap beads
84
, for locking the bristle plate
80
in place, with the bristles
82
projecting downwardly well below the lower end of the head housing
74
. The handle shaft
72
is preferably circular in transverse cross section and is dimensioned to be snap-fitted in the C-clip
53
of the dustpan-handle
50
(see
FIG. 2
) for attaching the two together. Also, as can best be seen in
FIGS. 2 and 3
, the broom head
75
and, in particular, the sloping sides
79
thereof, are dimensioned and shaped to nest in the leg recesses
57
of the dustpan handle
50
in a stowed condition, with the broom handle shaft
72
retained in the C-clip
53
just below the grip
73
. When thus stowed, the broom
70
can move with the dustpan handle
50
and does not interfere with either its pivoting or sliding movements.
Thus, after the broom
70
has been attached to the dustpan handle
50
, preferably when the handle
50
is in its upright use position, the dustpan handle
50
can be pivoted downwardly to its storage position. Then, when the dustpan handle is held upright, the dustpan receptacle
21
will, by gravity, hang freely with the couplers
65
in their forwardmost positions against the stop lugs
38
. The receptacle
21
may then be supported on its rear end wall
22
and the handle
50
and attached broom
70
may be dropped into the receptacle
21
, with the retaining extensions
58
respectively riding over the retaining projections
40
(see
FIGS. 2
,
3
and
8
). Thus, the engagement of the retaining extensions
58
with the retaining projections
40
prevents pivotal movement of the handle
50
toward the top wall
26
, while engagement of the broom head housing
74
with the receptacle bottom wall
30
prevents pivotal movement in the opposite direction, so that the combination
10
will remain balanced on the receptacle rear end wall
22
and not tip over.
When it is desired to use the combination
10
, the joined handles are simply grasped and pulled upwardly, allowing the receptacle
21
to drop away until the couplers
65
stop against the stop lugs
38
at the forward ends of the rails
35
, as shown in FIG.
10
. Then, the receptacle may be laid down with its bottom wall
30
on the floor
15
and the handle
50
pivoted to its use position, as explained above (see FIG.
11
), whereupon the broom
70
can be disengaged from the handle
50
for use, as shown in FIG.
12
.
Preferably, the combination
10
is formed of suitable plastic materials, except for the Tinnerman washers
46
and the handle grips
52
and
73
. The broom bristles
82
may also be formed of suitable plastic materials. Preferably, the receptacle
21
, the handle yoke
55
and the broom head
75
are of molded, one-piece construction, as is the bristle plate
80
. However, it will be appreciated that, if desired, other materials and fabrication techniques could be used.
From the foregoing, it can be seen that there has been provided an improved dustpan and broom combination, wherein the dustpan handle can be easily moved between storage and use positions with one hand, by undergoing a combined pivoting and sliding movement, and the broom can be stowed on the dustpan handle without interfering with its pivoting and sliding movements.
The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While a particular embodiment has been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution.
