Abstract: There is provided an access panel for releasably covering an aperture in a structure, the access panel including a panel member having inner and outer sides, and a panel stop extending from said inner side. The access panel includes a mounting member attached to the inner side adjacent a first edge to engage the structure. The access panel also includes a movable clip member slidably mounted on the panel member. The clip member comprises a casing and a mounting flange secured to a first end of the casing. The casing is linearly movable over the panel stop. The mounting flange is adapted to engage the structure proximate an opposed second edge of the panel member. The access panel also includes a spring situated within the casing between the first end of the casing and the panel stop for biasing the clip member toward the second edge in use.

Abstract: A removable cover for covering an access opening in a structure includes a plate member having two opposite side edges and front and rear sides. An elongate clamping member has two opposite end sections each forming an elongate clamping element and each extending towards a respective one of the side edges from a central region of the plate member. The clamping member is formed from a flexible material and is attached at a central portion thereof to the rear side of the plate. The two opposite end sections are substantially rigid while a central section has at least one flexible transverse portion. A separate spring device is mounted on the clamping member and has two elongate spring arms projecting outwardly in order to engage and bias the clamping elements towards engagement with the rear side of the plate member.

Abstract: A multipurpose device useable as a cover for a hatch opening in recreational vehicles and vessels. The device includes several panels connected together and adjustable straps for removable attachment to a resident hatch or closure panel. When installed on a fully or partially open hatch, the device is useful to increase ventilation and reduce the entrance of rain or water passing through the hatch opening. The device is multiform and multipurpose and can be used for alternate recreational activities when not installed as a hatch opening cover.

Abstract: An access panel for installation over an opening in panelling of a wall or ceiling of a structure includes a plate having two opposite side edges and a positioning flange extending rearwardly from a rear surface of the plate, this flange being located inwardly from adjacent edges. The panel includes two elongate clamping elements, each extending towards a respective one of the side edges from a central region of the plate attached to a rear side of the plate. Each clamping element is made of a resilient springy material so that an outer end portion can be pulled away from the plate during installation. These elements are used to secure the panel to opposite sides of the opening. Preferably each clamping element has a special profile to enable fast and easy installation over the opening.

Abstract: A detachable panel or grill for covering an opening in panelling of a wall or ceiling or in an appliance. The panel can be installed quickly and rigidly without the need for any special framing. The panel or grill can be installed or removed by the rotation of a single screw which passes through a threaded opening in an elongate fastening arm. The arm extends generally parallel to an inner surface of the panel during use thereof. The arm is pivotable relative to the panel between a first position usable for insertion of the arm into the opening and a second position used for clamping the panel to edge structure defining the opening. A slideway is connected to an inner surface of the panel and limits the extent of pivotal movement of the arm. The screw extends through a hole in the panel and connects the arm to the panel. A spring biases the arm so that it pivots towards the second position.

Abstract: A removable access door for covering small openings in walls and ceilings includes a panel member and at least two devices for removably attaching the panel member to the structure. Each device includes a clamping member pivotally mounted adjacent a side edge of the panel and an engagement member for pivoting the clamping member from a first position that permits the clamping member to be inserted into the opening towards a second position where the clamping member extends behind an edge section of the structure. The engagement member is connected to its respective clamping member and is movable to an initial position to engage and be actuated by an edge section of the structure as the attaching device is inserted into the opening. A spring biases the attaching devices to swing the clamping members to the second position and releasably clamp the edge sections. The door can be easily removed with the use of a screwdriver inserted behind the edge of the panel.
