Patent Application
20190368874
The present invention relates to level apparatuses and, more particularly, to a level apparatus for chainsaws.
When chainsaw users flush cut a stump when cutting a tree down, it is hard to make the chainsaw saw stay at a level angle through the bottom cut. By keeping the chainsaw level the user can cut all the way around the stump and stay within the same cut of the tree.
As can be seen, there is a need for a level apparatus for chainsaws.
In one aspect of the present invention, a chainsaw level apparatus includes a vial having a planar portion and a transparent or translucent curved portion, the planar portion engaging at least a periphery of the curved portion; and a fluid encased a vial cavity defined by the curved and planar portions.
In another aspect of the present invention, the chainsaw level apparatus includes a vial having a planar portion and a transparent or translucent curved portion, the planar portion engaging at least a periphery of the curved portion; a fluid encased a vial cavity defined by the curved and planar portions; a bubble accommodated by said fluid; a center marking at a center of a curvature of the curved portion; and an adhesive layer provided along the planar portion beyond the periphery of the curved portion.
In yet another aspect of the present invention, a method of indicating that a chainsaw blade is in a horizontal orientation during use includes the steps of providing the above-mentioned chainsaw level apparatus and adhering said chainsaw level apparatus via the adhesive layer to a portion of the chainsaw that is coplanar with said chainsaw blade so that during use the user can determine if the bubble is resting near the center marking.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
and
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, an embodiment of the present invention provides a level apparatus for chainsaws that can be adhered to pre-existing chainsaws for indicating when a user is keeping the chainsaw level through a cut. The level apparatus may include a transparent vial defined by a curved portion and a planar portion engaging the curved portion along its periphery so that a fluid be may encased between the curved and planar portion. The fluid may accommodate a bubble that in a level state occupies the marked center of the curved portion, and wherein a non-level state the bubble slides along the inner portion of the curved portion accordingly, thereby indicating to the user that the level apparatus is not level.
Referring to
The level apparatus 12 may include a slightly curved transparent vial 30 with constant inner diameter at each viewing point. The vial 30 may have a curved portion 34 and an interconnecting planar rear portion 32 defining a vial cavity. The vial cavity may be incompletely filled with a fluid 16, such as alcohol or the like, leaving a bubble 14 in the encased fluid 16. As seen in
In certain embodiments, the level apparatus 12 may provide an adhesive layer 18 along an outer portion of the planar portion 34 so that the level apparatus 12 may be retrofitted (affixed) to a pre-existing chainsaw 10.
A method of using the present invention may include the following. The level apparatus 12 disclosed above may be provided. A user may attach said level apparatus 12 to a side of a chainsaw 10, enabling the user to keep the chainsaw 10 at a perfectly level position when cutting a tree 20.
Additionally, the level apparatus 12 can be used on any tools that needs to be applied on a level basis.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
