Description
``` 212~463 The present invention relates to a dustpan and more particularly, to improvements in dustpans.
Dustpans are well known in the art and are used to pickup dust or debris following a sweeping operation. Many such dus~pans are known in the art with the basic dustpan comprising a base, a rear wall, a pair of side walls, and a relatively short handle extending horizontally from the rear wall in a plane which is generally parallel to the base.
This type of dustpan requires bending over or stooping of the person using the same and to obviate this, there have been proposals in the art for various types of dustpans which incorporate extended handles. Thus, for example, there is shown a dustpan having an extended handle and with a spout for emptying collected debris in U.S. Patent 2~864,117 to Williams. Other arrangements having extended handles include, for example the dustpan of U.S. Patent 4,562,611 wherein an elongated handle is provided with the dustpan pivotably mounted on the handle for emptying purposes.
Some of the problems which still exist with such dustpans is the relationship of the handle to the dustpan.
Typically, when using the dustpan for a plurality of operations, one must leave the dustpan by itself while continuing a sweeping operation. Most of the known dustpans will have the handle fall down to the floor thereby again requiring a stooping or bending operation by the person using the dustpan. ~lso, a similar problem occurs when the dustpan is to be stored. ~t is desirable that the pan can be stored with the handle in an upright position and easily removed therefrom.

- 2 -```~ 2123463 -It is an object of the present invention to provide a dustpan wherein the handle will remain in an upright position without requiring any exterior support.
It is a further object of the present invention to provide a dustpan which is simple and economic to manufacture.
According to one aspect of the present invention, -~
there is provided a dustpan which includes a substantially planar base member having a front edge, a rear edge and a pair of side edges which extend between the front and rear --edges. A rear wall extends upwardly from the rear edge of ---the planar base member, with the rear wall also being angled inwardly towards the base member to thereby form an angle o~
less than 90 with respect thereto. Side walls extend upwardly ~rom the side edge. There is provided a handle - -receiving member which is adjacent the rear wall, the handle receiving member being such that when a handle is attached thereto, the handle can be supported by the rear wall when in -~
an upright position.
In greater detail, the dustpan may be formed of di~ferent materials which are well known in the art including, for example, a metallic material. However, for reasons which will become apparent hereinbelow, it is particularly pre~erred that the dustpan be formed as a single unit o~ a plastic material. The particular plastic material can be selected ~rom many such known materials; however, it is preferred that the plastic material have the property o~
being ~lexible a~ a certain thic~ness and also being durable and capable o~ being ~lexed a number o~ times without --~``` 2123~63 substantial deterioration of the material.
As is conventional, the base member of the dustpan will have a substantially planar configuration. In this respect, it will be understood that the base member may be formed such that the front edge i5 beveled to assist in pickup of the dust or debris and indeed, the base member may be itself slightly angled to better place the front edge in contact with the surface on which the debris is to be picked up. In other words, when placed on the floor, the base member may be somewhat inclined with respect to the floor as is well known in the art.~
,~ Side walls are provided for the purpose of ¦ containing the dirt or debris which is picked up and as such, ¦ may be formed in different configurations including having a --¦~ somewhat triangular shape with an angled upper edge as i~
well known in the art.
The rear wall of the dust pan, as previously mentioned, is preferably formed integrally with the base member and extends upwardly and inwardly with respeck thereto such that the angle between the base member and the rear wall is less than perpendicular or 90. Preferably, the rear wall is angled inwardly such that it forms an angle of between 2 and 15 with rcspect thereto.
The handle receiving member of the dustpan can be formed in several different manners. Thus, the attachment between the handle and the dustpan may be such as ko permit rotational movement in at least one direction through use of a suitable joint. It is essential that the attachment be such that the handle i8 pivotable through a range where at ~ 4 -;~ 2123~63 one extremity, it can lie adjacent the rear wall and then be pivotable to a more rearward position.
In a preferred embodiment, the handle receiving member has a portion thereof which functions as a hinge member. To this end, a portion of the handle receiving member may comprise a substantially planar extension of the ~-base member and which is of a thickness so as to permit -flexing thereof. This hinge member, as previously mentioned, is preferably formed integrally with the main portion of the dustpan; in an alternative, a separate portion may be used ¦ and suitably secured to the pan by adhesive means or welding --or a similar operation. -~
The means of attaching the handle to the handle receiving element may be selected among many known arrangements.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of a dustpan according to the present invention;
Figure 2 is a perspective view illustrating the rear wall portion thereof;
Figure 3 is a perspective view illustrating movement of the handle;
Figure 4 is a perspective view similar to Figure 1 of a further embodiment;
Fiyure 5 is a perspective view similar to Figure 2 of the embodiment of Figure 4; and _5_ ~,. . . .
-` 2~23~63 Figure 6 is a perspective view of the embodiment of Figure 4 showing movement of the handle.
Referring to the drawings in greater detail, and by reference characters thereto, the dustpan includes a base 10 which is of a g~nerally rectangular configuration and has a front edge 10, a rear edge 14 and a pair of opposed side edges 16 and 18.
Extending upwardly from side edges 16 and 18 respectively are side walls 20 and 22. As may be seen, side walls 20 and 22 are of a somewhat triangular configuration and merge to meet a rear wall 24 which extends upwardly from rear edge 14. A reinforcing rib 26 is formed in rear wall 24. Also, as may be seen from the drawings, base portion 10 has a rib 28 which extends along front edge 12 to assist in retaining dust or other debris which is placed in the dustpan.
Rear wall 24, while extending upwardly from rear edge 14 of base 10, does so at an inwardly inclined angle for reasons which will become apparent hereinafter.
Rear wall 24, as may be seen from Figure 2, has a pair of parallel ears or flanges 30 extending outwardly from the rear wall. Flanges 30 each have an aperture extending therethrough. A coupling member 32 having internal threads formed therein, is secured to flanges 30 by means of a pin which extends through coupling member 32 and flanges 30.
A handle 36, which has a gripping portion generally designated by reference numeral 38, is screw threadedly engaged with coupling member 32.
~"!ij~ " ~ ,; " ~ "~, " ~
2123~63 As shown in Figures 1 to 3, the dustpan may include retaining means for the handle and to this end, a pair of retaining clips 40 and 42 may be formed inte~rally with rear -wall 24 and are of a somewhat flexible nature such that they are adapted to retain handle 36.
¦ As shown in Figure 3, the pivotable connection ¦ between coupling member 32 and the dustpan permits rotational movement of the handle as indicated by arrow 44. Also, as may be seen in Figure 1, the inward angled rear wall 24 permits the handle 36 to remain in an upright position when -the dustpan is in its normal ready to use orientation. Thus, handle 12 which essentially lles parallel to rear wall 24 forms an angle 48 with respect to a vertical line 46.
Referring to Figures 4 to 6, a further embodiment of the invention is illustrated with many of the components being similar to that of Figures 1 to 3 and thus, will not be described in detail.
In the embodiment of Figures 4 to 6, there is provided a base 50 having a dirt retaining rib 52 extending along the front edge thereof. Side walls 54 and 56 extend upwardly from the base as does an inwardly angled rear wall 58.
An integrally formed flange 60 extends outwardly -from base 50 (Figure 6) and is of a flexible nature. A ;~
coupling member 62 is also formed to receive handle 64 by means of a friction fit.~ It will be noted that coupling member 62 may include a clip member 64 adapted to engage the upper peripheral edge 68 of rear wall 58.
