A system for anchoring unmanned aerial vehicles to surfaces includes a landing pad configured to be installed on an agricultural machine, with the landing pad defining a landing surface. Furthermore, the system includes an unmanned aerial vehicle (UAV) configured to land on the landing surface and a top surface of a field across which the agricultural machine is traveling. The UAV, in turn, includes an anchoring device configured to engage soil within the field to anchor the UAV to the field when the UAV has landed on the top surface of the field. Additionally, the anchoring device is further configured to engage the landing pad to anchor the UAV to the landing surface when the UAV has landed on the landing pad.

A wheel immobilization device for preventing unintended movement of a wheel of a mobile object of a type having a wheel includes a rope body that includes a first end and a second end opposite the first end and that has an elongate, pliable, and flexible configuration, the rope body having a plurality of strands twisted together between the first and second ends. The immobilization includes a tail portion situated at the first end of the rope body, the tail portion having a linear configuration and a leader end. The immobilization device includes a retaining portion opposite the tail portion and situated at a second end of the rope body, the retaining portion including a loop that defines a head opening configured and operable to receive the tail portion therethrough.

The novel bladder systems and tie down systems set forth herein provide systems and apparatuses that mitigate or prevent damage, such as tipping over/capsizing, of a watercraft stored on shore or an aircraft secured to a ground surface during adverse wind, rising water, or storm events. Further, novel apparatuses and methods for storing a watercraft using the bladders as cushioning or holding devices when installed within a cavity, whether the cavity is created by digging a hole or building an enclosing berm, provides additional stability and security for the watercraft during adverse wind, rising water, or storm events.

The invention relates to a wheel chock for blocking a stationary wheel having a bottom surface (1) for resting on a floor and a wheel surface (2) for engagement with the wheel. The wheel surface (2) is provided for blocking the wheel angled to the bottom surface (1). The bottom surface (1) and wheel surface (2) are connected to each other via a hinge and designed to be foldable. A locking device is arranged movably on the bottom surface (1) and/or the wheel surface (2) and, in a locking position, locks the bottom surface (1) and wheel surface (2) in an unfolded, angled state.

The utility model relates to a pluggable two-way tire slip stopper, which is used for solving the problem of sliding when a vehicle is parked. The pluggable two-way tire slip stopper includes two slip stoppers, the back portions of the two slip stoppers are plugged together via a slot in a protrusion manner, the two slip stoppers are identical in structure, and the slip stopper includes the anti-slip portion of a front end and the plug portion of a rear end, the anti-slip portion is integrally formed with the plug portion, the plug portion is in the shape of a square, the plug portion is a triangular column shape with an obliquely upward surface, and the anti-slip portion is provided with a plurality of anti-slip belts, and the anti-slip belt is disposed at a certain distance, the upper surface of the anti-slip belt is inclined, and the anti-slip belt is provided thereon with a plurality of anti-slip protruding strips. The two slip stoppers of the utility model can be combined and plugged together, can be used in combination, and uses a two-wheeled vehicle to prevent slippage, whose effect is very good. The utility model has the advantages of scientific design, convenient use and good use value. The utility model is light and durable, convenient to carry, safe and convenient.

A system for anchoring unmanned aerial vehicles to surfaces includes a landing pad configured to be installed on an agricultural machine, with the landing pad defining a landing surface. Furthermore, the system includes an unmanned aerial vehicle (UAV) configured to land on the landing surface and a top surface of a field across which the agricultural machine is traveling. The UAV, in turn, includes an anchoring device configured to engage soil within the field to anchor the UAV to the field when the UAV has landed on the top surface of the field. Additionally, the anchoring device is further configured to engage the landing pad to anchor the UAV to the landing surface when the UAV has landed on the landing pad.

The wheel chock handling unit includes a base, an articulated cantilever arm assembly, a main spring assembly and a force-compensation mechanism. The arm assembly has a first end pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position. It also has a second end receiving a wheel chock. The main spring assembly extends between the arm assembly and the base. The force-compensation mechanism includes a lever pivotally mounted to the base for angular displacement in a plane that is substantially parallel to that of the arm assembly.
