The umbrella is positioned adjacent the cup holder to cover the cup holder. The umbrella includes a shaft and a cover. The shaft has a top end and a bottom end coupled to the inflatable body. The shaft is inflatable to project from an outer surface of the inflatable body and deflatable to be collapsed. The cover is coupled to the top end of the shaft. The cover is inflatable to project radially from the shaft and deflatable to be collapsed.

A hydrofoil vehicle comprises a frame and at least one foil. The vehicle comprises a moveable control surface configured to control a pitch of the vehicle, in use. A locking mechanism is provided for restricting movement of the control surface when the vehicle is not foiling, for example during launching. In examples, the locking mechanism activates automatically when the hydrofoil vehicle is not foiling. In examples, the vehicle is human powered.

The utility model relates to the field of water leisure boat, especially a spliced inflatable water leisure boat, including inflatable leisure boat, installation cover, crossbar, connecting frame and support rod etc., inflatable leisure boat is equipped with left and right two, and the upper side of two parts of inflatable leisure boat is connected with left and right two installation cover, and four installation covers on the same horizontal position are all connected with crossbar, and connecting frame is connected between crossbar, and the middle part of crossbar is connected with support rod in front part. The utility model uses the cooperation of connecting square tube, hollow square tube and screw rod to splice a proper number of the device, after splicing, by pulling the pull -out plate to remove and rotating and snap ring clamping reinforcement, then the device is pushed into water for use, can place the articles carried on the hollow plate, so that the device can be spliced for use while realizing reinforcement and facilitating article placement, convenient for adapting to different number of people and activity demand, enhancing structural stability and safety, flexible and convenient to use.

Example systems and methods are provided herein for generating paths for watercraft. Such systems include a memory and a processor, and the processor is configured to determine a set of condition parameters that each correspond to desired conditions for a potential navigation path, select at least one condition parameter from the set of condition parameters, and then determine and apply a constraint relaxation to the selected condition parameter(s) to form constraint relaxed condition parameter(s), each of which increases a range of input values that satisfy the corresponding desired conditions for the potential navigation path. The processor is also configured to determine a region based on an updated set of condition parameters, including the constraint relaxed condition parameter, and then to determine a navigation path within the region.

Various implementations include a tower having one or more legs, a top section, and a linkage mechanism. Each leg includes at least one leg portion and a mount for coupling the tower to a water craft. A proximal end of one leg portion is rotationally coupled to the mount. A distal end of each leg portion is rotationally coupled sequentially to the proximal end of another leg portion. The top section is rotationally coupled to the distal end of the last leg portion of each leg. The leg portions of each leg are rotatable such that the tower is movable between a lowered position and a raised position. The linkage mechanism rotationally clocks the rotational movement of the mount to the top section causing the top section to be non-rotatable relative to the mount of the leg.

The utility model discloses a kind of yacht can be opened boarding gate device, belong to ship outfitting technical field, including ship body and ship gate, the side of the ship gate is provided with built-in cavity, and lock handle mechanism is arranged on the ship gate and located the inside of built-in cavity, locking cavity is opened in the side of built-in cavity on the ship body, and lock head is fixedly connected with the inside of locking cavity on the ship body, two groups of hinges are arranged between the ship gate and the ship body, and the ship gate is rotatably connected on the ship body by two groups of hinges, the utility model, by lock whole hidden design, the use of boarding gate is improved beautiful, while the double-layer structure of sealing part and positioning groove blocks water flow from seeping in;Finally hinge outer opening structure saves cabin space, handle labor-saving lever design, so that smaller force can be operated, limit column and reset spring double false opening mechanism, improve the security of boarding gate use.

This invention discloses a water bicycle, relating to the field of water sports equipment technology. It includes a buoyancy platform main frame, a steering mechanism at the top front end of the main frame, a seat fixedly connected to the middle area of ​​the main frame, a drive chain gear mechanism below the seat, and a rudder mechanism at the other end of the main frame. The main frame is fixedly connected to a steering bracket, a steering rod rotatably connected to the steering bracket, and a rudder plate fixedly connected below the steering rod. By sitting on the seat and stepping on the drive chain gear mechanism, the user indirectly drives a first adjustable rod and an outer fixed inner arc bearing to swing via an auxiliary rod. The outer fixed inner arc bearing pushes the rudder to swing left and right on a universal joint, simulating human rowing. By replacing human rowing with mechanical transmission, the efficiency of rowing can be greatly improved, and human labor consumption reduced.

An object moving device comprises a drive device, an inner cable that is wound and unwound by the drive device, a moving member that is raised and lowered together with a moving object by winding and unwinding of the inner cable, a guide rail extending in a moving direction of the moving object, wherein the guide rail slidably engages with the moving member and is capable of guiding a movement of the moving member, a cushioning member provided on the moving member, and a receiving portion that is provided on a member mounted to the guide rail and abuts onto the cushioning member to restrict the movement of the moving member. The receiving portion is a structure having a high frictional force portion provided at a site where the receiving portion abuts onto the cushioning member.
