Description

BACKGROUND INFORMATION

Field of the Invention

The invention relates to windscreens, particularly those for use with outdoor sports and activities.

Discussion of Prior Art

Many outdoor sports and activities, such as fishing, hunting, and gardening, frequently require a person to sit or crouch in a certain location while participating in the activity. Ice fishing, for instance, often involves sitting on a lake for an extended period of time while a fisherman waits to catch fish. The weather, and in particular the wind, is often an obstacle in the participants enjoyment of these types of activities.

That is particularly true with ice fishing as lakes in the winter are frequently subject to harsh winds. To enjoy ice fishing on windy winter days the sporting goods industry has created a number of huts and hut-like structures that are intended to shield a user from the weather. However, all are cumbersome to transport, to setup and to tear down.

What is needed, therefore, is an easily portable and easily assembled and disassembled windscreen.

BRIEF SUMMARY OF THE INVENTION

The invention is a portable windscreen that easily attaches to a support vehicle and shields the user from the wind when in use and that is easily transported when not in use. The windscreen generally includes a shield that is a relatively rugged sheet of material, the shield being supported by one or more support posts and secured to the support vehicle using one or more securing means. When not in use the shield and securing means are easily wrapped around the support post for compact transport. To assemble the windscreen the shield is simply unwrapped, the support post mounted and the securing means attached to the vehicle.

The support vehicle may be, for example, a snowmobile or an all-terrain vehicle. The shield may come in a variety of shapes, for example, a shield that is relatively triangular in shape is particularly well suited for use with a snowmobile or all-terrain vehicle. In this example, a single support post may be used near the mid-point of the shield to hold the triangular shape, with the securing means attaching the ends of the shield to the front and rear of the support vehicle.

When properly attached to the support vehicle the windscreen effectively attaches to one side of the support vehicle, allowing the user to sit on the vehicles seat while being shielded from the wind. The user is then able to enjoy his/her activity, such as ice fishing on a windy lake.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.

FIGS. 1 and 2 illustrate the portable windscreen 100 according to the invention attached to a support vehicle V. At times the disclosure discusses the support vehicle V as a snowmobile, however, it is understood that snowmobiles are only used as an illustrative example and that the portable windscreen 100 may be used with other types of vehicles and is in no way limited to use with a snowmobile.

The portable windscreen 100 includes a shield 10, at least one support post 20 and securing means 30. When fully assembled the support post 20 supports the shield 10 in the vertical plane and the securing means 30 attach the shield 10 to the support vehicle V for support in the horizontal plane. When in a collapsed position for transport or storage the shield 10 is typically wrapped around the support post 20 and the securing means 30 may be used to hold the wrapped shield in position, after which the windscreen 100 is easily transported as shown in FIG. 6.

To assemble the portable windscreen 100 from a collapsed and transportable position, the user need only unroll the shield 10, insert the top post end 22 into or onto the shield top 12 while positioning the bottom post end 24 on a lower portion of the support vehicle V or on an adjacent ground surface, and then secure the securing means 30 to the ends of the vehicle V. In all, the process may be completed in very little time, potentially less than one minute for experienced users.

In the embodiment shown, the shield 10 is shaped roughly like a triangle, having a peak, or a shield top, 12, two shield ends 14 and a shield bottom 15. One support post 20 is included that has a top post end 22 and a bottom post end 24. Inserting or attaching the top post end 22 to the shield top 12 and placing the bottom post end 24 on the vehicle V or on an adjacent area of ground surface supports the shield 10 in the vertical plane. The securing means 30 attaches the two shield ends 14 of the shield 10 to the support vehicle V to support the shield 10 in the horizontal plane and further secure the position and strength of the shield 10.

The shield 10 is comprised of a lightweight and rollable but sturdy material. A wide range of materials are acceptable for the shield 10, however, sturdy materials such as a canvas or other closely woven clothes that are made of linen, cotton, and/or other synthetic fibers such as nylon, polyester, aramids and carbon fibers are best. For example, those materials that are used for making sail boats sails and/or heavy-duty tarps are particularly suitable for the shield 10.

The top post end 22 is insertable into an upper securing post receiver 16 in the peak 12 of the shield 10. The upper securing post receiver 16 may be any form of receiver that is suitable for securing the end of a post, such as, for example, a pocket that is made into the fabric as shown in FIG. 1 or a ring that attaches to or inserted/sown into the fabric. The bottom post end 24 is typically inserted into, or onto, the support vehicle V, however the bottom post end 24 may also be placed on a ground surface or it may inserted into a lower securing post receiver (not shown) on the shield that simply holds the shield vertically but does not attach to the support vehicle V or a ground surface.

The securing means 30 may be any suitable securing means, however, elastic cords such as bungee cords are particularly advantageous. Bungee cords in particular customarily have hooks on either ends of an elastic cord that are easily attached to the shield 10 and vehicle V, and are commonly used with both snowmobiles and all-terrain vehicles. The shield ends 14 may have reinforced openings to secure a hook on a bungee cord.

In the embodiment shown, the support vehicle V is a snowmobile. This embodiment is particularly advantageous for ice fishing. To transport the windscreen 100 to the fishing site the shield 10 is wrapped around the support post 20 and securely fastened, either with the securing means 30 or an additional bungee cord or conventional ties (not shown). The disassembled windscreen 100 is then attached to, or held on, the snowmobile and the user rides to the preferred fishing site. The snowmobile is parked in a position perpendicular to the direction of the wind and the collapsed windscreen 100 is untied and assembled on the snowmobile V.

The top post end 22 of the support post 20 is inserted into the upper securing post receiver 16 and the bottom post end 24 is placed on or in the foot well area on the snowmobiles running boards FW. FIGS. 3-5 illustrate the post 20 in position on the support vehicle V without the shield 10. FIG. 4 illustrates one embodiment of the support post 20 that is designed to sit on the foot well FW and FIG. 5 illustrates a second embodiment of the support post 20 that is designed to fit in an opening O in the foot well FW. The support post 20 may also be secured in position by the snowmobile handlebar H as shown in FIG. 3.

The first securing end 14 is secured to the front F of the snowmobile V by the securing means 30 and the second securing end 14 is secured to the rear R of the snowmobile V by the securing means 30. Additional ties 32 may also be used as shown in FIG. 1 to further secure the shield 10, and in particular the bottom of the shield 10, to the support vehicle V.

After assembling the portable windscreen 100 and securing it to the snowmobile V the user may sit on the snowmobile's seat S and fish while being shielded from the wind. The approximately triangular shape of the shield 10 is advantageous for quick and convenient use, however, other shapes are also suitable. For example, the shield 10 may have an approximately rectangular shape, and additional support posts 20 may be used to fix or hold the shield 10 in different configurations. The additional support posts 20 may be attached to the shield ends 14 extending upward in the vertical direction to support the rectangular shield in the vertical plane, and additional support posts may extend along the top of the shield 10 in the horizontal plane to further secure and support the shape of the shield 10.

It is understood that the embodiments described herein are merely illustrative of the present invention. Variations in the construction of the portable windscreen may be contemplated by one skilled in the art without limiting the intended scope of the invention herein disclosed and as defined by the following claims.
