A device (1) for covering a surface is provided. The device includes: (a) a cover (10) of which each longitudinal edge is provided with a bead (12); (b) a rotatably mounted drum (2) capable of winding or unwinding the cover, movable on rails placed on either side of said surface; and (c) a system for continuously locking/unlocking the bead in the rails during the translation of the drum.

An apparatus for providing protection to a curb or a ledge against damage caused by physical contact to the curb or the ledge during performance of a sporting activity is disclosed. The apparatus includes a top component and a side component extending from the top component at an angle within an angle range of 60?-90?, wherein the top component and the side component are formed of steel, wherein the top component and side component are configured to be placed on the curb or the ledge. In some instances, the top component and the side component are integrally formed from a single sheet of 14 gauge cold-rolled steel, and wherein a bend is formed in the single sheet of steel to form the angle between the top component and side component. In some instances, the angle is 75? or 90?.

An apparatus for installing and removing glass panels and methods of using the apparatus are disclosed. The apparatus includes a base portion, a back support structure secured to the base portion, and a glass adjustment system moveably coupled to the back support structure. Methods for using the apparatus to install and remove glass panels from, for example, ice rink boards, are also disclosed.

A device for covering a is provided that includes (a) a cover, each longitudinal edge of which is provided with a protruding element; (b) a drum mounted so as to rotate on frames and capable of winding the cover; (c) a translation system for translatably moving the drum on rails that are placed on either side of the surface; (d) a system for continuously locking/unlocking the protruding element into/from the rails during the translation of the drum. The translation system includes: a first rotation means (M1) for activating the rotation of a closing axle that winds a pull cord (21) enabling the drum to be pulled in an opening direction (Do) along the rails. The drum (2) is translatably mounted so as to also be moved in translation along a component perpendicular to the plane (X, Y) so that the drum always rests on the surface or on the rails.

A device for covering a surface includes (a) a covering, each longitudinal edge of which is provided with a projecting element; (b) a rotatably mounted drum suitable for rolling up or unrolling the covering, and movable in translation on rails placed on either side of the surface; (c) a system for continuously locking/unlocking the projecting element in the rails during the translation of the drum. The projecting element includes a multitude of discreet elements distributed along each longitudinal edge separated from one another by an average distance (d).
