(7) Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list.

(8) FIGS. 1 and 2 illustrate an adjustable vault apparatus 10 for use on a ground surface 15, such as an animal competition track or the like. A base 20 has a width W and a length L for resting on the ground surface 15 in a substantially horizontal orientation. The base 20 is stable on the ground surface 15 and not prone to tipping, even if knocked by a running animal for example, since the center of gravity of the apparatus is substantially towards the ground surface 15 and W and L are sufficiently large (at least 24 inches each, for example). Preferably the base 20 is comprised of a width spanning member 22 having opposing ends 26, and a length spanning member 23 that are mutually fixed together to form a T-shaped base 21 (FIG. 4). In one embodiment, the base 20 is readily collapsible for facilitating breakdown and setup of the vault apparatus 10, and storage and transportation thereof.

(9) A pair of linear actuators 30 are mounted in a substantially vertical orientation with the base 20 at opposing sides 25 thereof, and in the embodiment having the width spanning member 22, at the opposing ends 26 thereof. In one embodiment, each linear actuator 30 is adjustably and selectively fixed along the width spanning member 22 so as to set the width W between the linear actuators 30 as desired so as to support jump bars 90 of varying lengths therebetween.

(10) Each linear actuator 30 is adapted to move a bar support 40 thereof vertically between a lowered position 50 (FIG. 5) and a raised position 60 (FIG. 2). The bar supports 40 are mutually opposing, facing each other across the width W of the base 20. Each bar support 40 is adapted to support one end of an elongated jump bar 90 at a bar trough 100 thereof, by gravity. As such, a slight bump by an animal (not shown) attempting to jump over the jump bar 90 causes the jump bar 90 to become dislodged from the bar trough 100, indicating a failed jump by the animal. Each jump bar 90 is preferably elongated, linear, and light in weight, as required by animal competition rules or the like. Further, each jump bar 90 may be made from an elastomeric or resilient material.

(11) In one embodiment, each bar support 40 is adapted to support the ends of two jump bars 90 in parallel, each at two different heights above the ground surface (FIG. 4). In such an embodiment, preferably the bar support 40 is comprised of a lower bar support 41 slidably engaged with an upper bar support 49, such that at the lowered position 50 the lower bar support 41 slides up and is sandwiched between the upper bar support 49 and the base 20 (FIG. 5).

(12) Each linear actuator 30 moves the bar support 40 in accordance to a control circuit 70 electrically connected with each linear actuator 30 and a power source 80. The power source 80 may be an external source such as an AC adapter or line voltage (not shown), or a battery 81 (FIG. 3), for example. A control signal received by the control circuit 70 causes the control circuit 70 to actuate each linear actuator 30 to either raise or lower in unison each bar support 40 and the at least one jump bar 90, the at least one jump bar 90 preferably remaining level while being moved either up or down.

(13) Preferably each linear actuator 30 includes a motor 110 (FIG. 3) enclosed in a motor enclosure 120 and connected with a lower end 132 of a threaded shaft 130 that extends upwardly through a shaft enclosure 140. The shaft enclosure 140 includes a longitudinal slot 150 traversed by the bar support 40. A proximal end 42 of the bar support 40 includes a threaded portion 160 rotationally engaged with the threaded shaft 130. A distal portion 48 of the bar support 40 terminates at the bar trough 100. The longitudinal slot 150 rotationally fixes the bar support 40 within the linear actuator 30, while allowing the bar support 40 to be raised or lowered in accordance with the direction that the motor 110 spins the threaded shaft 130. A top end 148 of the shaft enclosure 140 may include a shaft cap 170 having a central aperture 175 through which an upper end 138 of the threaded shaft 130 is rotationally captured, thereby maintaining the position of the rotational axis of the threaded shaft 130 within the shaft enclosure 140. Preferably each motor enclosure 120 is made from a rigid plastic or metal material and sealed against water ingress.

(14) In one embodiment, a first motor enclosure 121 includes a battery 81 as the power source 80, and the control circuit 70. In such an embodiment, the control circuit 70 of the first motor enclosure 121 drives the motors 110 of both the first motor enclosure 121 and a second motor enclosure 122 (FIG. 2). As such, the base 20 includes at least one electrical conductor 180 for powering the motor 110 of the second motor enclosure 122, the circuit being completed through the base 20 that is metallic and electrically conductive. Alternately, at least two electrical conductors 180 may be included between the motor enclosures 120 when the base 20 is non-conductive, such as when made from a rigid or non-flexible plastic material for example. Preferably each conductor 180 includes at least one releasable connector 190 (not shown with conductors 180) so that if the vault apparatus 10 is physically impacted, the base 20, motor enclosures 120, and each conductor 180 will all separate so as not to damage the at least one conductor 180.

(15) The first motor enclosure 121 may include a pair of the control connectors 190, whereby an external control line 16 may be connected with each of the control connectors 190 to direct the circuit 70 to power each motor 110 to either raise or lower the at least one bar support 90. In an alternate embodiment, the control circuit 70 of at least the first motor enclosure 121 includes a wireless receiver 200, whereby a wireless control signal may be received by the wireless receiver 200 and conveyed to the circuit 70 for powering each linear actuator 30 to either raise or lower the at least one bar support 90.

(16) In an alternate embodiment of the invention, each motor enclosure includes its own battery 81 or other power source 80, and its own circuit 70, whereby each linear actuator operates independently to receive the control signal, either through the wired control line 16 or wirelessly, to power the linear actuator 30 to either raise or lower the at least one bar support 90.

(17) In one embodiment, each linear actuator 30 may include a wing mount 210 (FIG. 2) opposite the bar support 40 for securing a wing 220 laterally away from the jump bar 90. Such a wing mount 210 may be a pair of magnets 230, for example, or other mechanical support that is readily collapsible.

(18) While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, the linear actuators 30 herein are described as being rotational threaded shafts, but other types of linear actuators 30 could be utilized as well, such as pneumatic or hydraulic linear actuators 30.
