Line trimmer support ski

A support ski for mounting to a line trimmer to support a trimmer in a spaced relationship to a ground surface. The ski is attachable to a line guard typically present on conventional trimmers and extends from a rearward position thereof to a forward position underneath the rotating line. The ski includes a pointed tip for permitting a forward sliding motion of the trimmer over the ground, and further includes upwardly curved side edges for allowing a lateral motion of the associated trimmer. An alternate embodiment of the present invention includes an adjustment means for selectively adjusting a relative height of the trimmer to the ground surface.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to trimmer supports and more particularly 
pertains to a line trimmer support ski for mounting to a line trimmer to 
support the trimmer in a spaced relationship to a ground surface. 
2. Description of the Prior Art 
The use of trimmer supports is known in the prior art. More specifically, 
trimmer supports heretofore devised and utilized for the purpose of 
supporting a trimmer are known to consist basically of familiar, expected 
and obvious structural configurations, notwithstanding the myriad of 
designs encompassed by the crowded prior art which have been developed for 
the fulfillment of countless objectives and requirements. 
For example, an adjustable carriage for electric string trimmers is 
illustrated in U.S. Pat. No. 4,688,376 in which a light weight tubular 
frame has a central resilient housing-clamping mechanism adapted for 
holding a string trimmer. A plurality of castors are mounted to the 
tubular frame and quick detach forward/quick attach features enable the 
string trimmer to be used conveniently by itself or when desired. In 
addition, the carriage is provided with two height adjustment provisions 
and a convenient tilt adjustment for positioning the spring trimmer 
relative to the ground. 
A weed and grass trimmer is described in U.S. Pat. No. 5,048,615 in which 
three wheels are used to support the weight of the trimmer. Cutting height 
is adjusted by way of an adjustable height arm and a secondary handle is 
provided to receive and translate an upward urging force into a tipping 
motion of the trimmer. The cutting head can be easily removed and a brush, 
snowblade, or blower can be installed thereto for accommodating a 
plurality of long care tasks. 
Another patent of interest is U.S. Pat. No. 4,922,694 which discloses a 
wheeled support for a line trimmer that allows the trimmer to be used as a 
wheeled lawnmower or a wheeled edger. The lightweight, two wheeled support 
is adjustable for use with substantially all line trimmers. 
Other known prior art trimmer supports are disclosed in U.S. Pat. No. 
5,095,687, and U.S. Pat. No. 4,077,191. 
While these devices fulfill their respective, particular objectives and 
requirements, the aforementioned patents do not disclose a line trimmer 
support ski for mounting to a line trimmer to support the trimmer in a 
spaced relationship to a ground surface in which the ski is attachable to 
the trimmer line guard and extends from a rearward position thereof to a 
forward position underneath the rotating line and which further includes a 
pointed tip for permitting a forward sliding motion and upwardly curved 
side edges for allowing a lateral motion of the associated trimmer. 
Furthermore, none of the known prior art trimmer supports teach or suggest 
a line trimmer support ski which still further includes an adjustment 
means for selectively adjusting a relative height of the trimmer to the 
ground surface therebeneath. 
In these respects, the line trimmer support ski according to the present 
invention substantially departs from the conventional concepts and designs 
of the prior art, and in so doing provides an apparatus primarily 
developed for the purpose of mounting to a line trimmer to support the 
trimmer in a spaced relationship to a ground surface. 
SUMMARY OF THE INVENTION 
In view of the foregoing disadvantages inherent in the known types of 
trimmer supports now present in the prior art, the present invention 
provides a new line trimmer support ski construction wherein the same can 
be utilized for mounting to a line trimmer to support the trimmer in a 
spaced relationship to a ground surface. As such, the general purpose of 
the present invention, which will be described subsequently in greater 
detail, is to provide a new line trimmer support ski apparatus which has 
many of the advantages of the trimmer supports mentioned heretofore and 
many novel features that result in a line trimmer support ski which is not 
anticipated, rendered obvious, suggested, or even implied by any of the 
prior art trimmer supports, either alone or in any combination thereof. 
To attain this, the present invention essentially comprises a support ski 
for mounting to a line trimmer to support a trimmer in a spaced 
relationship to a ground surface. The ski is attachable to a line guard 
typically present on conventional trimmers and extends from a rearward 
position thereof to a forward position underneath the rotating line. The 
ski includes a pointed tip for permitting a forward sliding motion of the 
trimmer over the ground, and further includes upwardly curved side edges 
for allowing a lateral motion of the associated trimmer. An alternate 
embodiment of the present invention includes an adjustment means for 
selectively adjusting a relative height of the trimmer to the ground 
surface. 
There has thus been outlined, rather broadly, the more important features 
of the invention in order that the detailed description thereof that 
follows may be better understood, and in order that the present 
contribution to the art may be better appreciated. There are, of course, 
additional features of the invention that will be described hereinafter 
and which will form the subject matter of the claims appended hereto. 
In this respect, before explaining at least one embodiment of the invention 
in detail, it is to be understood that the invention is not limited in its 
application to the details of construction and to the arrangements of the 
components set forth in the following description or illustrated in the 
drawings. The invention is capable of other embodiments and of being 
practiced and carried out in various ways. Also, it is to be understood 
that the phraseology and terminology employed herein are for the purpose 
of description and should not be regarded as limiting. 
As such, those skilled in the art will appreciate that the conception, upon 
which this disclosure is based, may readily be utilized as a basis for the 
designing of other structures, methods and systems for carrying out the 
several purposes of the present invention. It is important, therefore, 
that the claims be regarded as including such equivalent constructions 
insofar as they do not depart from the spirit and scope of the present 
invention. 
Further, the purpose of the foregoing abstract is to enable the U.S. Patent 
and Trademark Office and the public generally, and especially the 
scientists, engineers and practitioners in the art who are not familiar 
with patent or legal terms or phraseology, to determine quickly from a 
cursory inspection the nature and essence of the technical disclosure of 
the application. The abstract is neither intended to define the invention 
of the application, which is measured by the claims, nor is it intended to 
be limiting as to the scope of the invention in any way. 
It is therefore an object of the present invention to provide a new line 
trimmer support ski apparatus which has many of the advantages of the 
trimmer supports mentioned heretofore and many novel features that result 
in a line trimmer support ski which is not anticipated, rendered obvious,

trimmer support ski which is of a durable and reliable construction. 
An even further object of the present invention is to provide a new line 
trimmer support ski which is susceptible of a low cost of manufacture with 
regard to both materials and labor, and which accordingly is then 
susceptible of low prices of sale to the consuming public, thereby making 
such line trimmer support skis economically available to the buying 
public. 
Still yet another object of the present invention is to provide a new line 
trimmer support ski which provides in the apparatuses and methods of the 
prior art some of the advantages thereof, while simultaneously overcoming 
some of the disadvantages normally associated therewith. 
Still another object of the present invention is to provide a new line 
trimmer support ski for mounting to a line trimmer to support the trimmer 
in a spaced relationship to a ground surface. 
Yet another object of the present invention is to provide a new line 
trimmer support ski in which the ski is attachable to the trimmer line 
guard and extends from a rearward position thereof to a forward position 
underneath the rotating line. 
Even still another object of the present invention is to provide a new line 
trimmer support ski which includes a pointed tip for permitting a forward 
sliding motion of the trimmer over the ground, and further includes

line trimmer support ski which further includes an adjustment means for 
selectively adjusting a relative height of the trimmer to the ground 
surface therebeneath. 
These together with other objects of the invention, along with the various 
features of novelty which characterize the invention, are pointed out with 
particularity in the claims annexed to and forming a part of this 
disclosure. For a better understanding of the invention, its operating 
advantages and the specific objects attained by its uses, reference should 
be had to the accompanying drawings and descriptive matter in which there 
is illustrated preferred embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIGS. 1-6 thereof, 
a first embodiment of a new line trimmer support ski embodying the 
principles and concepts of the present invention and generally designated 
by the reference numeral 10 will be described. 
From an overview standpoint, the line trimmer support ski 10 comprises an 
elongated ski 12 having a side member extending substantially upwardly 
from an end thereof and a pointed tip 16 formed at another end thereof. 
The side member 14 is shaped so as to define a side aperture 18 through 
which a side fastener 20 may be utilized to secure the side member to a 
rear of a line guard 22 of a conventional line trimmer 24, as best 
illustrated in FIG. 2. The side member angles and continues into an upper 
member 26 which lies substantially flat upon an upper surface of the guard 
22. The upper member 26 similarly includes an upper aperture 28 through 
which an upper fastener 30 may engage a portion of the guard 22. 
When installed upon the line trimmer 24, as illustrated in FIG. 2, the ski 
12 extends beneath the rotating line 32 of the trimmer. The tip 16 of the 
ski 12, however, should not extend past an average reach of the line 32, 
thereby allowing the line to contact ground growth before the ski 12. 
In use, the line trimmer support ski 10 may be easily installed to any 
conventional line trimmer 24 by simply fabricating two small holes within 
the guard 22 and installing the support ski 10 as shown in FIG. 2. The 
support 10 may be positioned upon a ground surface, whereby a substantial 
amount of weight of the line trimmer 24 is thereby supported. In addition, 
the line trimmer support ski 10 supports the line trimmer 24 at a uniform 
distance from the ground surface, thereby providing a more even cut to the 
grass and other growth being trimmed. 
More specifically, it will be noted that the line trimmer support ski 10 
comprises an elongated ski 12 which is integrally or otherwise connected 
to a substantially upwardly extending side member 14, as best illustrated 
in FIG. 3. The side member 14 extends upwardly from the ski 12 at an angle 
S of between 0 and 20 degrees away from the vertical. Preferably, the side 
member 14 extends upwardly from the ski 12 to define an angle S of 
approximately 5 degrees. 
The side member 14 angles and continues to define an upper member 26 which 
extends substantially outwardly therefrom at an angle U of between 0 and 
30 degrees from the horizontal. Preferably, the upper member 26 extends 
away from the side member 14 at an angle U of approximately 10 degrees 
from the horizontal. 
Both the side member 14 and the upper member 26 are provided with apertures 
18, 28 which allow fasteners 20, 30 to engage the guard 22, thereby 
securing the line trimmer support ski 10 to the associated line trimmer 
24. It has been found that by providing the support ski 10 with both 
vertical and horizontal mounting areas, i.e. the side member 14 and the 
upper member 26 respectively, the ski is more securely supported by the 
guard. In addition, such mounting arrangement reduces fatigue and stress 
upon the outer portions of the guard 22 while simultaneously precluding a 
rotation of the support ski 10 about both horizontal and vertical axis. 
FIG. 4 is a cross-sectional view of the ski 12 and it can be seen from this 
Figure that the ski is shaped so as to define respectively opposed 
upwardly curved edges 34 which cooperatively define a downwardly 
positioned convex surface 36. The convex surface 36 is the portion of the 
ski 12 which rests upon the ground and, because of the upwardly curved 
edges 34, allows the ski 10 to laterally translate over rough or uneven 
terrain. 
As best illustrated in FIG. 3, the upwardly curved edges 34 of the ski 12 
tapper off as they approach the side member 14 so as to define a flat area 
38 which allows the ski 12 to resiliently pivot slightly with respect to 
the side member. Thus, the presence of the flat area 38 between the side 
member 14 and the ski 12 provides a resilient coupling between the ski and 
the side member and imparts a slight shock absorbing capability to the 
line trimmer support ski 10. 
The ski 12, in addition to defining the upwardly curved edges 34, further 
includes an upwardly pointed tip 16 which permits a forward translation of 
the line trimmer support ski 10, and the associated line trimmer, over 
rough or uneven terrain. The tip 16 is integrally formed as a part of the 
ski 12 and extends upwardly therefrom to a point below the rotating line 
32 so as to not interfere with the cutting capabilities of the line. In 
addition, and as best illustrated in FIG. 2, the tip 16 of the ski 12 
should not extend past a reach of the line 32. Preferably, the tip 16 
extends to a distance D behind the outermost reach of the line 32, wherein 
D is between approximately 1/4 of an inch and 6 inches. Most preferably, 
the distance D behind the outermost reach of the line 32 to which the tip 
16 extends is equal to approximately 2 inches. 
FIGS. 5 and 6 are a top plan view and a perspective view, respectively, of 
the line trimmer support ski 10 and it can be seen from these Figures that 
the support ski may be easily constructed of a single piece of metal such 
as steel, aluminum, or the like. In addition, it is within the intent in 
preview of the present invention to provide a line trimmer support ski 10 
made of any conceivable material, including plastics and the like. 
In use, the line trimmer support ski 10 may be easily installed to any 
conventional line trimmer 24 by simply fabricating two small holes within 
the guard 22 and installing the support ski 10 as shown in FIG. 2. The 
support 10 may be positioned upon a ground surface, whereby a substantial 
amount of weight of the line trimmer 24 is thereby supported. In addition, 
the line trimmer support ski 10 supports the line trimmer 24 at a uniform 
distance from the ground surface, thereby providing a more even cut to the 
grass and other growth being trimmed. 
A second embodiment of the present invention as generally designated by the 
reference numeral 40 which comprises substantially all of the features of 
the foregoing embodiment 10 and which further comprises a height 
adjustment means 42 will now be described. As best shown in FIGS. 7-8 it 
can be shown that the height adjustment means 42 comprises an adjustable 
member 44 which, instead of the side member 14, is connected to the upper 
member 26. The adjustable member 44 is shaped so as to define the side 
aperture 18 through which the side fastener 20 may be positioned and 
secured to couple the adjustable member 44 and the upper member 26 to the 
guard 22 of the line trimmer 24 as described above. 
The side member 14 of the second embodiment 40 includes an elongated 
aperture 46 which extends vertically and longitudinally therealong and the 
adjustable member includes a pair of adjustment fasteners 48 which are 
fixedly secured to thereto and are operable to extend through the 
elongated aperture 46, thereby to adjustably couple the adjustable member 
44 to the side member 14 . By this structure, the adjustment fasteners 48 
may be loosened, the ski 12 may be adjustably positioned to a desired 
height or distance from the line trimmer 24, and the adjustment fasteners 
48 retightened to secure such adjustment. The adjustment means 42 of the 
second embodiment 40 allows a user to selectively vary the cutting height 
provided by the line trimmer support ski 10 to accommodate various terrain 
and cutting requirements. 
As to a further discussion of the manner of usage and operation of the 
present invention, the same should be apparent from the above description. 
Accordingly, no further discussion relating to the manner of usage and 
operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
