Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to dusting,
In particular, it relates to dusting with a pivoting base.

[0002]

BACKGROUND OF THE INVENTION Conventional dustpans include a base and often a cover surrounding a storage cavity in the base. A long shaft or rod is attached to the base by a yoke. The handle at the top of the rod allows the user to grab and move the dustpan. The yoke allows the base to pivot so that the front of the base lifts when the rod is lifted to carry the assembly. The yoke also allows the base to pivot so that the front of the base is lowered when the rod is lowered to allow the user to sweep debris into the dustpan.

Conventional dustpans are not properly designed to prevent the base from wearing out during pivoting. When a conventional dustpan is lowered or lifted off the ground, the trailing edge of the base contacts the ground and wear can occur. Conventional dustpans have a wear pad on the base to minimize the effect of wear.

Also, conventional dusting is not properly designed to easily remove dust and dirt.
Conventional dustpan bases often have sharp inner corners. Dust and dirt accumulate in such corners, making it difficult to clean the base.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dustpan having a wear reducing member.

[0006]

SUMMARY OF THE INVENTION An advantage that can be realized with the present invention is that the base is lifted off and lowered to such a surface to sweep debris from the ground or other surface into the base. Sometimes the wear of the base is reduced.

Another advantage that can be realized with the present invention is that the user's ability to clean the base is increased.

[0008] Other advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. .

[0009] According to one aspect of the invention, the dustpan includes a base for collecting debris, the base having at least one wall formed for receiving a rolling member.
A handling member is connected to the base. At least one rolling element is disposed on at least a part of the at least one wall.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention. Things.

A preferred embodiment of the dustpan according to the invention is shown in FIGS. This dedusting comprises a base 1, a handling member 2 and at least one rolling member 7.

The base 1 preferably has five faces: a right face 11, a left face 13, a top face 12, a bottom face 14, and a back face 15. Surfaces 11, 12, 13, 14, 15
Forms a cavity 23 that can sweep out dust, dirt and other debris. The bottom surface 14
It has a wall 6 for receiving a rolling member 7. Although a single wall 6 can be provided for receiving one or more rolling members 7, in the preferred embodiment shown, a wall is provided for each rolling member 7. The bottom surface 14 also has an inclined surface return 5 provided to keep dust and other debris within the base after it has been swept into the base. Top surface 12 has a substantially flat leading edge 8 and a substantially curved trailing edge 9.

The base 1 has a wall 6 and a surface return 5 formed therein.
The inner surfaces of 2, 13, 14, 15 are designed to form one substantially continuous surface. When the corners of the base (otherwise made by joining the sides of the base 1) are rounded to form a substantially continuous surface, especially when the debris is sticky, Filth,
Eliminating corners where dirt and other debris can be trapped aids in cleaning the base.

The rear face 15 of the base 1 preferably has a slot 10 slightly below the rear edge 9 of the top face 12. This slot is preferably wide enough to receive four fingers. The user can use the slot 10 to hold the base 1 in a desired position. For example, the user may lift the
Can be held parallel to the ground. Also, when the user discards the contents of the base 1, the user holds the base 1 through the slot 10, thereby preventing the contents falling from the base 1 from touching while the base is empty. be able to. Keeping the user out of the debris in this way helps prevent the user from being contaminated by the contents of the base. The ability to keep the user from touching the debris is particularly advantageous in the medical field where debris swept into the base 1 may contain bodily fluids that may cause the user to become infected with an infectious disease.

The handling member 2 is preferably a shaft or a rod. More preferably, rubber maid
Commercial Products LLC (Rubbermaid Commercial
Products LLC) (part number 2534), such as an ergonomic handle
A handle can be provided as part of the handling member 2. The cross section of the handling member 2 can have any shape. Furthermore, the handling member 2 is preferably hollow (to reduce the total weight of the dust), but may be solid. If the handling member 2 is hollow with a circular cross section, it preferably has an elongated tubular shape.

Preferably, a yoke 3 is provided for connecting the handling member 2 to the base 1. The lower portion 16 of the yoke 3 can be pivotally attached to the right and left surfaces 11 and 13 of the base 1 by hinge pins 25 at pivot points 4. Lower part 16 of yoke 3
Is wider than the upper part 17 of the yoke 3, thereby giving the yoke 3 a substantially triangular shape. The upper part 17 is connected to the lower end 18 of the handling member 2. This connection can be achieved by connecting the upper part 17 to the lower end 18 by molding, or more preferably by connecting the upper part 17 and the lower end 1.
It can be established in a number of ways, such as by providing a complementary screw (not shown) on 8.

As shown in FIG. 5, the rolling member 7 on the base 1 is preferably a wheel. The rolling member 7 is provided to suppress abrasion of the bottom surface 14 (particularly, back corners and edges) of the base 1 when the base is lifted off the ground or lowered on the ground. Rolling member 7 has a small diameter, preferably 1.25 inches.

The rolling member 7 prevents the bottom surface 14 (particularly the back portion) of the base 1 from rubbing against the ground, thereby suppressing abrasion of the bottom surface 14 when the base 1 is lifted off the ground or lowered onto the ground. I do. For example, when the handling member 2 is lifted, the front 2
1 starts pivoting upward towards the lower end 18 of the handling member 2. The back 22 of the bottom surface 14 can roll on the ground via the rolling member 7 when the base 1 pivots. Wear is reduced by allowing the back 22 to roll over the ground rather than rub it. Similarly, when the base 1 is lowered onto the ground, the rolling members 7 are initially positioned to contact the ground, whereby the front 21 of the base 1 starts a downward pivoting. If the user continues to lower the base 1 after the rolling member 7 contacts the ground, the back portion 22 will roll along the ground via the rolling member 7 as the front portion 21 continues to pivot downward. Due to this rolling property, abrasion of the bottom surface 14 is suppressed.

The user can carry this assembly by the handling member 2. When the user lifts the handling member 2, the front portion 21 of the base 1 is lifted and pivots in the direction of the lower end 18 of the handling member 2.
At this time, the back 22 of the base 1 is initially in contact with the ground. When the front part 21 finishes the turning movement, the back part 22 is lifted off the ground if the user lifts the handling member 2 sufficiently high. The turning motion of the front part 21 is
This is realized by pivotally attaching the yoke 3 to the base 1 at the pivot point 4. When the base 1 is lifted from the ground, the yoke 3 is located substantially near the bottom surface 14 of the base 1. On the other hand, when the base 1 is placed on the ground, the yoke 3 is located substantially near the front edge 8 of the top surface 12 of the base 1.

Preferably, a cover 20 is provided on the base 1. The cover 20 can be attached to the upper surface 12 of the base 1 by a hinge pin 26 located at the clip point 19. In a dustpan having the cover 20, the lower end 18 of the handling member 2 can be pivotally supported on the cover 20 through the cavity 24, whereby the lower end 18 of the handling member 2 can be engaged with the upper portion 17 of the yoke 3. . When the base 1 is on the ground, the handling member 2 holds the cover 20 in the open position (FIG. 1) so that a user can sweep dirt, dust and other debris onto the base. Conversely, when the base 1 is lifted off the ground, the handling member 2 forces the cover 20 into a closed position (FIG. 3) in which the cavity 23 of the base 1 is closed, whereby the debris retained on the base 1 Is covered.

In order to eliminate the undesired box-like appearance of a conventional dustpan, the base 1 is substantially rounded. To achieve this goal, the right side 1 of the base 1
1 and left surface 13 are generally curved in a direction from a position abutting on bottom surface 14 to a position abutting on top surface 12. When the cover 20 is included, the cover
It is rounded in two directions, generally in the direction from the leading edge 8 towards the surface return 5 and in the direction generally from the right side 11 to the left side 13. Finally, the top surface 12 is rounded generally in the direction from the leading edge 8 to the trailing edge 9 and, as mentioned above, the trailing edge 9 itself is also rounded.

When manufacturing the above-described dustpan, it is preferred that all parts are manufactured from lightweight plastic. By using a lightweight plastic, the overall weight of the dustpan can be reduced, thereby allowing the user to easily lift the base when emptying the dustpan, or not to use the dustpan Sometimes the assembly can be easily transported and the refuse can be easily transported.

In view of the foregoing improvements, other obvious improvements are within the scope of the dusting claimed in the present invention. For example, the handling member can be attached to the base by a structure other than the yoke. Also, various handles can be formed on the handling member or can be removably attached to the handling member.

[0027] Other embodiments of the invention will be apparent to those skilled in the art from a consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.

[0028]

According to the present invention, there is provided a dustpan having at least one rolling member on the back, and the rolling member suppresses abrasion of the base when the base is lowered to the ground and when the base is lifted from the ground. Was provided.
