Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

A system for practicing roping of a steer may include a towing apparatus configured to tow a steer roping practice apparatus across a ground surface, a central anchor device configured to define a fixed anchor point with respect to the ground surface, an elongated guide member attachable at a first end to the central anchor device and attachable at a second end to the towing apparatus to guide the towing apparatus along a circular path about the central anchor device, and a turning device configured to engage the elongated guide member between the central anchor device and the towing apparatus in a manner causing the towing apparatus to make a turn on the ground surface from the circular path. The system may also include a mechanical steer roping practice apparatus movable across the ground surface and removably hitched to the towing apparatus.

The bicycle ramp of the present invention is foldable and easily transportable. The bicycle ramp of the present invention may be built directly onto a utility trailer with a foldable gate and wheels and thus is transportable to be pulled along the back of a suitable vehicle using the hitch. The bicycle ramp of the present invention creates an inclined surface for bicycle riding applications, including the teaching of a beginning cyclist skills such as balancing and pedal. There is a receiving slot to engage the rear wheel of the bicycle at the flat upper section of the bicycle ramp. The receiving slot stabilizes the bicycle in a static position until a releasable stopper is released to launch the rider down the angled sections of the bicycle ramp.

The invention relates to a padel court construction for playing padel, the padel court construction comprising a padel field; at least two panels configured to at least partly enclose the padel field; and at least one strut configured to connect the at least two panels to each other. The padel court construction further comprising a ground profile configured to guide the at least two panels in relation to each other, and an adjustment element configured to displace at least one of the panels in relation to the ground profile.

A mobile fitness plaza configured to be coupled to or integrated into a vehicle to provide mobile fitness stations to one or more users. The mobile fitness plaza includes one or more alcove compartments providing a storage space for exercise equipment and one or more awnings configured to be selectively adjusted between a stowed position and a deployed position to provide shelter and protection for equipment stowed therein and users positioned beneath the one or more awnings.

A deployable mobile trailer with multiple deployable walls is disclosed. The mobile trailer includes wheels rotatably coupled to a base and a frame attached to the base. The frame has vertical supports attached to the base and a top frame assembly disposed at a top end of the vertical supports. First and second elongate deployable walls are rotatably attached to respective first and second sides of the frame. The first and second walls include and are movable between respective retracted and deployed positions. A deployable end wall is rotatably attached to an end of the frame and has a retracted position and a deployed position between which it is movable. Multiple activity devices are removably attached to the top frame assembly, the first elongate deployable wall, the second elongate deployable wall, or the deployable end wall. A mobile activity structure and method for operating a mobile deployable activity structure are also provided.

An upper body exercise device for exercising in a cab of a semitruck includes a base that is configured to position on a floor of the cab of the semitruck. A frame is coupled to and extends perpendicularly from the base. A pullup bar is coupled to the frame proximate to a top of the frame. The pullup bar is configured to be grasped in hands of a user, positioning the user to perform an associated upper body exercise. Each of a pair of handles is coupled to and extends perpendicularly from a respective opposing side of the frame. The pair of handles is positioned between the base and the top of the frame so that each handle is configured to be grasped in a respective hand of the user, positioning the user to perform an associated upper body exercise.

The portable exercise system for use with a trailer or truck frame is configured for use with one or more bumper slots located on the rear bumper of the trailer. The portable exercise system for use with a trailer or truck frame is a kit that creates static structures that are attached to the trailer using the one or more bumper slots. The portable exercise system for use with a trailer or truck frame comprises a plurality of removable bollards and a plurality of grips. The plurality of removable bollards attach the plurality of grips to the one or more bumper slots. The plurality of removable bollards form the static structures. The plurality of grips allow for exercises that require a controlled change in elevation relative to the horizontal surface formed by the trailer.

A rooftop mount device for connecting to a roof of a portable gym and for attaching exercise equipment is described. The portable gym is a portable container, such as a shipping container, having a top surface, or roof, to which the rooftop mount is attachable. The rooftop mount device includes connection members. The rooftop mount can also include one or more horizontal stabilization members and equipment attachment elements. The connection members are attached to a roof of the container. Exercise equipment is attached to the parts of the rooftop mount device. The rooftop mount provides proper height and stability for the bars, racks, stands, cages, rigs and riggings, and other exercise equipment that are attached to the container's roof so that the equipment does not move during use by an exerciser. Systems and kits are also described, which include a rooftop mount device, various exercise equipment, and a portable container.
