Abstract: A tensioning system for a shade structure is presented. The tensioning system comprises a shade membrane coupling portion configured to couple to a shade membrane of the shade structure. The tensioning system also comprises a movement axis, along which the shade membrane coupling portion moves. In a first direction, the shade membrane coupling portion applies tension to the shade membrane and, in a second direction, releases tension applied to the shade membrane. The tensioning system also comprises a force translation mechanism configured to receive a rotational force and translate it into linear movement of the shade membrane coupling portion along the movement axis in the first and second direction.

Abstract: A playground structure that includes a plurality of panels coupled to a frame so as to form at least the majority of regular polygon surfaces included in a uniform polyhedral shape.

Abstract: A tension-release mechanism configured to facilitate a coupling between a shade membrane and a support structure is provided. The tension-release mechanism comprises a coupling sleeve configured to be installed within the support structure. The tension-release mechanism also comprises a tension actuation element configured to extend along a connection path within the coupling sleeve. The tension actuation element is configured to engage a receiving feature within a moveable sleeve coupled to the shade membrane. Actuating the tension actuation element in a first direction causes the moveable sleeve to be received within the coupling sleeve. Actuation in a second direction causes the moveable sleeve to be decoupled from the coupling sleeve.

Abstract: A method of installing a releasable shade membrane to a shade system is presented. The method comprises installing a tension release system within a structural component of the shade system. The tension release system comprises a threaded member configured to, when actuated, cause a coupling mechanism to move along an axis defined by the threaded member. The method also comprises coupling a shade membrane to the coupling mechanism. The method also comprises actuating the threaded member in a first direction, such that the coupling mechanism moves along the axis in a tensioning direction. The tension release system is configured to release applied tension upon actuation of the threaded member in a second direction, causing the coupling mechanism to move along the axis in a release direction. The release direction is substantially the reverse direction of the tensioning direction.

Abstract: A multi-use container with wheels, which includes: an opening; a base; lateral walls; end faces; a lower edge around the lateral walls and the end faces; at least two wheels coupled to each external face of the lateral walls, close to the lower edge of the lateral walls and the lower corners of the container; and recesses in the opening for receiving a lower part of the wheels of a container stacked on top. The base projects from underneath the lower edge.

Abstract: A cardholder for labelling containers designed for storing, transporting, distributing and delivering all types of products or parts. The cardholder includes an upper longitudinal edge, a lower longitudinal edge, and lateral edges, all of which surround and protect a frame, the frame including a transparent sheet. The upper longitudinal edge includes a trapezoidal opening having a slope that increases from bottom to top for inserting a label, and the lateral edges include female projections that couple to lugs included in the walls of the container.

Abstract: It is desirable to protect playground structures from direct exposure to sunlight. The present invention relates to a system and method for providing shade for playground structures to provide such protection. Playground structures include columns used to support the playground structure. A shade fixture can be made comprising shade material over supporting structural members, including at least one column. Such a shade fixture can be secured to a playground structure by attaching the column of the shade fixture to multiple columns of the playground structure. It may be desirable to have the length of a shade fixture column be variable to account for variable playground structure column heights. The one column creates a bridge between columns. The columns can be adjacent to each other or at a distance. The bridge creates a more rigid structure and supports the weight of the shade material.
