DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
While the present invention is described with reference to embodiments described herein, it should be clear that the present invention is not limited to such embodiments. Therefore, the description of the embodiments herein is merely illustrative of the present invention and will not limit the scope of the invention as claimed.
As generally described herein, FIGS. 1-9B illustrate embodiments of a windscreen 10. As shown in FIG. 1, the windscreen 10 generally comprises a body portion 20 removeably secured to one or more bases 30. The windscreen 10 is capable of being positioned adjacent a fire 40, for example, to protect the fire 40 from the wind. It is to be understood that the windscreen 10 may provide protection from the wind while starting the fire, while containing the fire, and while cooking over the fire. Such protection may also allow the smoke generated from the fire to travel upwardly and dissipate in the air and prevent ash and/or smoke from being blown in an area surrounding the fire.
As best shown in FIGS. 2A and 2B, the body portion 20 has a first side 50 capable of being positioned adjacent the fire 40, and a second side 60 opposite the first side 50 to face away from the fire 40. It is to be understood that the first side 50 may be constructed from any material including, but not limited to, metal, such as steel or aluminum, glass, plastic, refractory materials, ceramics, composites, and the like. For example, the first side 50 may be constructed from a fireproof material or a heat reflective material capable of reflecting heat away from the first side 50. In a non-limiting example, the body portion 20 may be made from a material capable of being rolled into a substantially cylindrical shape for shipping or storage.
It is to be understood that the second side 60 may be constructed from any material including, but not limited to, the materials used for the first side 50. In a non-limiting example, the first side 50 and second side 60 may be a see-through or clear material, such as glass or plastic. It is also to be understood that the first side 50 and second side 60 may be provided in a variety of finishes, including, but not limited to a polished finish.
In a non-limiting example, the second side 60 may be constructed of a material having low thermal conductivity. Illustrative examples include, but are not limited to, composites, fireproof boards, blankets, and the like. One or more handles 70 may be connected to or positioned along the second side 60 to allow the wind screen 10 to be carried or otherwise repositioned. As the second side 60 is constructed of a low conductivity material, the handles 70 are capable of remaining cool to the touch to allow a person to reposition the windscreen 10 without gloves or tools. Although the handles 70 are shown as integral with the second side 60, one of ordinary skill in the art will appreciate that a variety of handles 70 may be used.
As shown in FIG. 1, the body portion 20 may be removeably secured to the base 30 to support the body portion 20 in a substantially vertical orientation along a surface 97. As used herein, the surface 97 may include, but is not limited to, the ground, grills, grill supports, fire pit walls, and the like.
As shown in FIG. 1, the body portion 20 may have a curved shape. In an embodiment, the body portion 20 may be provided with one or more securing members 72 for removeably securing additional body portions 71, 80, and 82. Such a configuration reduces the size of the windscreen 10 during transportation and storage. For example, the securing member 72 may be positioned along one or more ends of the body portion 20 to secure a body portion 71 (hereinafter referred to as “the horizontal member 71”) thereto. In an illustrative example, as shown in FIGS. 3A and 3B, the securing member 72 may be positioned on or along the side 60 to removeably secure the horizontal member 71. As shown in FIGS. 3A and 3B, the securing member 72 may be in the form of a rail or track that allows for the selective positioning of the horizontal member 72 along the body portion 20. The securing member 72 may also be in the form of a protrusion capable of insertion in a corresponding channel (not shown) along the horizontal member 71 that allows the horizontal member 71 to be selectively positioned therealong. Accordingly, the horizontal member 71 may be selectively positioned from a first position as shown in FIG. 3A to a second extended position as shown in FIG. 3B, and any position therebetween. In either position as shown in FIGS. 3A and 3B, the body portion 20 and horizontal member 71 may form a curved shape capable of surrounding at least a portion of a fire.
It is to be understood that a locking mechanism 73 may be provided to secure the horizontal member 71 at any point between the first to the second position. The locking mechanism 73 may include, but is not limited to, pins, bolts, and the like. For example, the body portion 20 and horizontal member 71 may be provided with a series of apertures (not shown) capable of coaxial alignment for insertion of a pin or bolt therein to secure the horizontal member 71 at a desired position along the body portion 20. It is also to be understood that a fireside 74 and a backside 75 of the horizontal member 71 may be constructed of the same material as the first side 50 and second side 60, respectively.
In another embodiment, as best shown in FIG. 4, one or more body portions 80, 82 (hereinafter referred to as “the vertical members 80, 82”) may be provided. The vertical member 80 is capable of being removeably secured to the body portion 20 via the securing member 72, and extending vertically from the body portion 20. In a non-limiting example, as shown in FIG. 5, the securing member 72 may be in the form of one or more protrusions extending from the top 85 of the body portion 20. The bottom 90 of the vertical member 80 may be shaped to receive the securing member 72, for example, to form an interlock 95 with the securing member 72. It is to be understood, however, that one of ordinary skill in the art will appreciate that a variety of different securing members 72 may be used to removeably secure one or more of the horizontal member 71 and the vertical members 80, 82 to the body portion 20. It is also understood that the vertical member 80 may also be provided with a securing member 72 to removeably secure the vertical member 82 to the vertical member 80.
In an embodiment as shown in FIGS. 6A and 6B, the body portion 20 may be removeably secured to the base 30 in a slidable manner to allow the body portion 20 to be repositioned if, for example, the direction of the wind changes. As shown in FIG. 7, the base 30 may define a channel 100 capable of slidably receiving the body portion 20 therein. The base 30 may have a ball bearing portion 104 through which the body portion 20 extends. The ball bearing portion 104 may include one or more ball bearings 105 capable of engaging the sides 50, 60 to facilitate sliding the body portion 20 along the channel 100. As shown in FIGS. 6A and 6B, one or more additional bases 30 may be provided to increase the area that the body portion 20 may be positioned about the fire 40.
It is also to be understood that one or more connectors 110 may be provided for connecting a plurality of bases 30 along the path of the body portion 20. As shown in FIGS. 8A and 8B, the bases 30 may have selectively positionable feet 115 to accommodate uneven surfaces. For example, one or more grooves 120 may be provided along the length of the base 30 for selectively positioning the feet 115 therealong. For example, a knob 125 may be turned to loosen the feet 115 so that the feet 115 may be positioned along the groove 120 in a desired location. The feet 115 may be secured at a desired position by tightening the knob 125. It is to be understood, however, that one of ordinary skill in the art will appreciate a variety of other configurations for selectively positioning the feet 115 horizontally along the groove 120.
In addition, or alternatively, the feet 115 may be vertically adjustable. For example, the feet 115 may be capable of telescoping or otherwise extending to a desired elevation. In a non-limiting example, a level indicator 130 may be provided on the base 30 to facilitate proper alignment.
As shown in FIGS. 6A and 6B, the windscreen 10 may be provided with a wind sensor 135 capable of detecting the direction of the wind to facilitate proper positioning of the windscreen 10 adjacent the fire 40. In an illustrative example, the wind sensor 135 may be a windsock, weather vane, sail or other such device capable of automatically repositioning the body portion 20 along the bases 30 in response to the direction of the wind. It is to be understood that the wind sensor 135 may have many orientations with respect to the body portion 20, and that more than one wind sensor 135 may be utilized with the body portion 20.
In another illustrative example, a motor 140 may be provided that is capable of repositioning the body portion 20 along the base 30. A user, for example, may operate the motor 140 manually to selectively position the body portion 20 along the base 30. It is also to be understood that the wind sensor 135 may be operatively connected to the motor 140 so that the wind sensor 135 activates the motor 140 to position the body portion 20 in response to the direction of the wind. As shown in FIG. 6A, the motor 140 may be incorporated into one or more bases 30, and may for example rotate the ball bearings 105 to position the body portion 20 along one or more bases 30. However, it is to be understood that a variety of configurations may be utilized to allow the motor 140 to position the body portion 20. For example, the motor 140 may be a stand-alone unit separate from the base 30. It is also to be understood that any motor 140 may be used including AC and DC motors, and power may be supplied from any source including batteries.
It is to be understood that the windscreen 10 may be of any size, and in one illustrative example has a radius 20% larger than the fire or fire pit and the body portion 20 ranges from one to four feet high. It is also to be understood that a variety of other modifications and alterations can be made to the windscreen 10. In an illustrative example, ribs 145 may be provided for increased stability. In another non-limiting example as shown in FIGS. 9A and 9B, the windscreen 10 may include cut out or screened on designs 150 for a more decorative and customized appearance.
The invention has been described above and modifications and alternations will occur to others upon a reading and understanding of this specification. The claims as follows are intended to include all such modifications and alterations insofar as they come within the scope of the claims or the equivalent thereof.
