SNOW REMOVAL DEVICE
A shovel device designed for pulling along a surface to remove accumulated snow. The preferred device includes a substantially vertical blade having a curved surface, a pair of wheels, and a handle. The blade further includes an attachment collar, one on each surface of the blade. The handle is releasably attached to the blade through one of the two attachment collars to allow either pushing or pulling the blade through, e.g., a snow pile. The wheels, which may pivot about a vertical axis, are mounted to the convex surface of the vertical blade, via a bracket or other suitable connector, to facilitate movement of the device along a surface.
This application is a continuation-in-part of U.S. patent application Ser. No. 13/772,588 filed Feb. 21, 2013, and claims the filing priority of U.S. Provisional Application No. 61/601,851 titled “Snow Removal Device” and filed on Feb. 22, 2012.
TECHNICAL FIELD OF THE INVENTIONThe present invention relates to shovel devices. Particularly, the shovel device relates to a manual snow removing device for removing snow from a surface, such as a driveway, sidewalk, play area, and the like.
BACKGROUND OF THE INVENTIONSnow shoveling is a primary cause in countless physical injuries and fatalities every year in the U.S. Particularly, the heavy lifting required to clear even a small layer of snow causes many individuals to lift improperly, lose balance or just generally over-exert themselves, bringing about falls, upper and lower back injuries and, in some cases, heart attack. Combined with the cold that usually accompanies such snow conditions, and even the healthiest of individuals can find themselves headed for a local hospital.
Typical snow shovels are not self-limiting. Accordingly, people tend to attempt using the entire shovel area to scoop and lift snow. Even a small amount of water-laden snow at the end of a shovel can amount to great strain on a user. As mentioned, shoveling can be a dangerous undertaking for many individuals. Snow blowing is far safer, but the relatively high-cost of a dependable snow-blowing machine restricts use to those with the financial means.
These and other problems in the art are identified and resolved by the invention of the present application.
SUMMARY OF THE INVENTIONThere is disclosed herein an improved shovel which avoid the disadvantages of prior devices and methods while affording additional structural and operating advantages.
A shovel device is described and claimed. Generally speaking, the shovel device comprises substantially vertical blade, a handle fixed to a surface of the blade, and a set of wheels.
In one embodiment, a shovel device is described. The shovel device comprises a curved blade having a top and bottom edge, a handle removably fixed to a concave surface of the curved blade, and at least one wheel affixed to a convex surface of the blade.
In another embodiment, a manual snow moving device is disclosed. The device comprises a blade having a top edge and a bottom edge and curved about a vertical axis, a first attachment collar on the concave surface of the curved blade, a second attachment collar to the convex surface of the blade, a handle releasably attached to a surface of the blade through one of either the first attachment collar or the second attachment collar, and at least one wheel assembly affixed to the convex surface of the blade.
These and other aspects of the invention may be understood more readily from the following description and the appended drawings.
For the purpose of facilitating an understanding of the subject matter sought to be protected, there are illustrated in the accompanying drawings embodiments thereof, from an inspection of which, when considered in connection with the following description, the subject matter sought to be protected, its construction and operation, and many of its advantages should be readily understood and appreciated.
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated.
Referring to
With reference to the embodiment of
The wheels 16 are preferably provided in a single pair or multiple pairs, but the device 10 may use only a single wheel attached approximate a mid-line of the blade 12. The wheels 16 can be standard wheels, but are preferably about the size of typical push lawnmower wheels, for example. As the device 10 is predominately used on slick surfaces, significant tire tread will help grip such surfaces during use. A bracket 19 may be used to attach the wheel axle to the concave surface of the blade 12. A caster like swivel attachment (not shown) for wheels (or wheel pairs) may be used to connect to the bracket 19 to facilitate turning of the shovel device 10 during use.
To provide balance and stability to the device 10 in use, the handle 14 is preferably attached to the blade 12 approximate the center of gravity, while the wheels 16 are also preferably attached approximate the center of gravity. Attaching weighted structures to the blade 12 to lower the center of gravity and also increase the overall weight of the device 10 may also assist in overall stability. The preferred handle attachment configuration prevents the handle 14 from pulling the blade 12 downward at the top (i.e., tipping the blade 12), which would allow snow to pass under the blade. The wheels 16 counteract, to some extent, upward pull of the handle 14 on the blade 12 as well.
In use, the device 10 can be positioned at one end of a snow covered surface and pulled by the handle 14 toward an opposite side of the surface, thereby dragging the blade 12 across the surface to remove the snow. Reversing the motion deposits the accumulated snow. The motion can be repeated for the length of the surface to move all snow to one side, as desired, without ever having to lift the snow from the surface. The user can even stand to the side of the device 10 to move it along the surface and remove snow—similar to the motion of sweeping. This will prevent the snow from being packed down under the walking pressure of the user.
With reference to the embodiments of
The shovel device 110 of
With reference to, the embodiments of
When the handle 114 is inserted into the preferred collar, a locking mechanism such as a pin, clip, latch or similar device, may be used to releasably hold the handle 114 into the collar. For example, as shown in
The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have 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. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
