DETAILED DESCRIPTION OF THE INVENTION

[0021] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0022] As noted above, there is a long-felt need in the art for an improved gate. There also exists in the art a long-felt need for an expandable gate that allows a user to easily change the width of the gate per his or her specific needs in order to cover the opening of the corral or pen. Further, there exists a long-felt need in the art for a gate that allows a user to have access to gates having an adjustable width within one single gate. Finally, there is a long-felt need in the art for an expandable gate that can be quickly expanded and locked into an expanded position.

[0023] The present invention, in one exemplary embodiment, includes an expandable gate device that is primarily comprised of a frame that has at least one vertical member, at least one horizontal member, at least one horizontal expansion member, at least one diagonal member and at least one locking bolt. All components of the frame are preferably manufactured from a square or tubular metal such as, but not limited to, steel, iron aluminum or metal alloys. Further, the width and length of the frame and the members can be adjusted as needed in accordance with the particular size requirements of the user. The outermost vertical members on each side of the frame have at least one hinge and at least one latch to allow the frame to be attached to and secured to at least one fence post. All members of the frame and the horizontal members are preferably hollow, such that an interior space exists within each of the frame members.

[0024] The top surface of the horizontal member has at least one continuous opening that receives a bolt or other fastening member. The shaft of the bolt is positioned through the opening such that it is positioned within the interior space. A horizontal expansion member also resides within the interior space of the horizontal member to accommodate the fastening member. The top surface of the fastening member has a groove that receives the shaft of the bolt to allow the expansion member to be slid in to or out of the interior space, which in turn allows the width of the frame to become smaller or larger. Once the fastening member has been positioned at the desired location within the interior space to achieve the desired frame width, the body of the bolt can then be turned until the shaft sufficiently contacts the groove to prevent the fastening member from sliding further into or further out of the interior space. The groove may also have a fixedly-attached or removable and repositionable stop which ensures the frame remains at the desired width when in use, once the width has been set by the user using the expansion member.

[0025] Additionally, the expansion member can be partially removed from one horizontal member in order to allow the frame to partially separate, such that only a portion of the frame may be opened while the rest of the frame remains stationary until both halves of the frame are rejoined by reinserting the expansion member and securing the member with the bolt. The frame may further include at least one wheel assembly having a generally u-shaped frame, that may be fixedly or removably-attached to any member of the frame. Alternatively, in lieu of a wheel, a skid or ski may be used and placed on the bottom of the gate to allow the gate to be moved over muddy ground or snow without a wheel getting caught in the mud or snow. The frame of the wheel assembly further receives at least one wheel or skid that allows the frame to be easily pushed to allow the gate to easily open and close when needed.

[0026] Accordingly, the expandable gate of the present invention is particularly advantageous as it provides a gate that can increase or decrease in width based on the needs of the user. Further, the device allows a user to have access to gates that can be changed to multiple widths and lengths. Finally, the device can be quickly expanded and locked into the expanded position. The gate may also have removable padding applied over the bars to reduce the risk to animals and equipment when traversing the opening.

[0027] Referring initially to the drawings, FIG. 1 illustrates a perspective view of one potential embodiment of an expandable gate 100 of the present invention while attached to two fence posts 10 in accordance with the disclosed specification. The device 100 has a frame 110 with at least one vertical member 120, at least one horizontal member 130, at least one horizontal expansion member 140, at least one diagonal or bracing member 150 and at least one locking bolt 170 (see FIG. 3). All components of the frame 110 are manufactured from square or tubular metal, such as but not limited to steel, iron, aluminum or other metal alloys, unless otherwise specific herein. It is further contemplated that in any embodiment, the width and length of the frame 110 and the members 120, 130, 140, 150 can be varied as needed per the size requirements of the opening of the corral or livestock pen. Further, the members can be arranged 120, 130, 140, 150 in any suitable position, orientation or arrangement that ensures structural stability to the frame 110. In addition, the frame elements can be personalized to create an emblem of the ranch or farm.

[0028] In order to allow the frame 110 to attach to at least one fence post 10, the outermost vertical members 120 on each side of the frame 110 have at least one (but preferably two) hinge elements 122 and at least one latch 124. The hinge 122 may be adjustable or fixed in position on the vertical frame member 120. The hinge 122 and the latch 124 are of a type known in the art with specific respect to fences and gates. The latch 124 further allows the frame 110 to be secured or unsecured from a fence post 10 by lifting or lowering the latch 124. The hinge 122 further allows the device 100 to pivot around the fence post 10 opposite the latch 124. In differing embodiments, the hinge 122 and the latch 124 may be removably or fixedly-secured to the vertical member 120. Padding 121, 123, 125 and 127 may be added to different portions of the frame 110 of the gate 100. The padding elements are movable and removable so as to avoid damage to livestock or equipment traversing the gate.

[0029] FIG. 2 illustrates a perspective view of one potential embodiment of an expandable gate device 100 of the present invention in accordance with the disclosed specification. It is further preferred that all members 120, 130, 140, 150 of the frame 110 or at least the horizontal members 130 are hollow, such that an interior space 136 exists within each of the members 120, 130, 140, 150. Further, any surface of any member 120, 130, 140, 150, but preferably the top surface 132 of the horizontal member 130, has at least one continuous opening 134. FIG. 2 also shows a skid 137 attached to the base of one of the extending elements 135 which can be used to move the gate 100 along muddy surfaces or through snow. In addition, the skid 137 can be used as a foot to prevent the gate from sinking in wet soil or mud when it is not suspended between fence posts.

[0030] FIG. 3 illustrates an enhanced perspective view of one potential embodiment of an expandable gate 100 of the present invention in accordance with the disclosed structure. The continuous opening 134 further receives at least one bolt or fastening member 170 that may be of any threaded or slot bolt type or other pin such as a “carter” pin having a head, and in one embodiment is preferably a wing nut bolt. The shaft 174 of the bolt 170 is positioned through the opening 134 such that it resides within the interior space 136. A horizontal expansion member 140 further resides within the interior space 136 of the horizontal member 130, and the ends 148 of the member 140 are preferably tapered. In differing embodiments, the member 140 may also be vertical and reside in the interior space of the vertical member 120 such as shown in FIG. 2. The top surface 142 (or in any alternative embodiment, any surface) of the member 140 includes a groove 144 that receives the shaft 174 of the bolt 170. In one embodiment, the groove 144 is on the bottom surface of the member 140 to remain protected from weather. To this effect, the expansion member 140 can be slid in to or out of the interior space 136 to allow the frame 110 to become smaller or larger in width, as needed to fill the opening to the corral or livestock pen. Once the member 140 has been positioned at the desired location within the interior space 136 to achieve the desired frame 110 width, the body 172 of the bolt 170 can be turned until the shaft 174 sufficiently contacts the groove 144 to prevent the member 140 from sliding further into or out of the interior space 136, as best seen in FIG. 4. In addition, the groove 144 may have a fixedly-attached or removable and repositionable stop 146 that is attached to the shaft 174 of the bolt 170 in the event that the member 140 attempts to slide inwards into the interior space. In this regard, both the bolt 170 and the stop 146 ensure the frame 110 remains at the desired width once the width has been set by the user using the expansion member 140, 133, and/or 135. Each expansion member 140 may also include a gauge 141 to aid the user in setting each expansion member at the correct position whether horizontally or vertically.

[0031] FIG. 5A and FIG. 5B illustrates perspective views of one potential embodiment of an expandable gate 100 of the present invention while separated and while attached in accordance with the disclosed specification. It is contemplated that the expansion member 140 can be partially removed from one vertical member 120 in order to allow the frame 110 to partially separate into individual portions. In this manner, only a portion of the frame 110 may be opened while the rest of the frame 110 remains stationary (and attached to a fence post 10) until both halves of the frame 110 are rejoined by reinserting the expansion member 140 and securing the member 140 with the bolt 170 or bolts 170. In order to facilitate the movement of the frame 110 over a ground surface 12, the frame 110 may further include at least one wheel assembly 160 or skid 137 (see FIG. 2). The assembly 160 has a generally u-shaped frame 162 that may be fixedly or removably-attached to any member 120, 130, 140, 150 of the frame 110. In one optional embodiment, the frame 162 further receives at least one wheel 164 or skid, ski or foot that allows the frame 110 to be easily pushed to allow the device 100 to easily open and close when needed.

[0032] FIG. 6 shows the gate assembly 100 of the present invention in which the frame 110 has been provided with a personalized indicia 601 in the form of an “M.” Any other shapes, designs or the like are possible depending on the personalization preferences of the individual purchasing the gate.
