Access doors

1. An access door adjustable to an opening having a size defined by a width and a height, comprising:

a frame adjustable to the size of the opening; and

a door panel, of a size at least the size of the opening;

wherein said frame adjustable to the size of the opening comprises side members and corner members;

each corner member comprising two arms, each arm comprising a receiving surface and a positioning pin extending perpendicularly from said receiving surface;

each side member having a section adapted to receive an edge of the opening and comprising a first part adapted to lay flat on an outer surface of the edge of the opening and a second part extending within the opening along a surface generally perpendicular to said outer surface of the edge of the opening, said second part comprising engagement positions along a length thereof, said receiving surface of a corner member being adapted to align the first part of a side member with the corner member, said positioning pin of the corner members being adapted to connect by snapping, with one of the engagement positions of the side member, between a maximum length for each side of the frame, by using outermost engagement positions along the length of the side member on each side of the side member, and a minimum length for each side of the frame, by using innermost engagement positions on each side of the side member, to adjust to the size of the opening, thereby directly forming a frame adjusted to the width and the height of the opening and adapted to directly receive said door panel for closing said opening;

and wherein said door panel comprises at least one glide on an inner surface thereof, said glide comprising a part rising from said inner surface of the door panel and having a distal end, and at least one corner member comprises a notch, said distal end being aligned with said notch and adapted to engage said notch of the corner member.

2. The access door of claim 1 , wherein said second part of said side member comprises foldable tabs, said tabs being foldable, inside the opening, generally perpendicularly to said outer surface of the edge of the opening, thereby locking the frame into place within the opening.

3. The access door of claim 1 , further comprising at least one cable connected between the corner member and said glide.

4. The access door of claim 1 , wherein said door panel comprises a lock, said lock comprising a proximal end secured to an inner surface of the door panel and a distal end, and at least one side member comprises, on said second part extending within the opening along a surface generally perpendicular to said outer surface of the edge of the opening, a locking slot adapted to receive said distal end of the lock.

5. The access door of claim 4 , wherein said lock comprises a slot at the distal end thereof and a series of holes along a length thereof, allowing different locations to adjust to the size of the frame, for securing the lock to the door panel by said proximal end of the lock so that the distal end of the lock is able to engage the locking slot of said second part of the side member.

6. The access door of claim 1 , wherein said side members are metallic members and said corner members are plastic members.

7. The access door of claim 6 , wherein said door panel is metallic and at least one corner member comprises an embedded magnet.

8. The access door of claim 1 , wherein two consecutive of said side members are connected together by one of said corner members by selecting an engagement position of the side members for snapping with said positioning pin of the corner members.

9. The access door of claim 1 , wherein the second part of at least one of the side members comprises at least one tab adapted to be foldable, outward of the opening, generally parallel to the outer surface of the edge of the opening.

10. The access door of claim 1 , wherein at least one of i) said corner members and ii) said side members comprises telescopic parts.

11. The access door of claim 1 , wherein the positioning pin comprises a detent.

12. An access door adjustable to an opening, in a wall, ceiling or floor panel, the opening having a size defined by a width and a height, comprising:

a door panel, of a size at least the size of the opening, said door panel comprising at least one glide on an inner surface thereof, said glide comprising a part rising from said inner surface of the door panel and having a distal end;

side members adjustable to the size of the opening, each side member comprising a first part adapted to lay flat on an outer surface of an edge of the opening and a second part adapted to extend within the opening along a surface generally perpendicular to said outer surface of the edge of the opening and comprising foldable tabs and positioning slots along a length thereof;

corner members, each corner member comprising two arms, each arm comprising a receiving surface and a positioning in extending perpendicularly from said receiving surface, and at least one corner member comprising a notch;

wherein the receiving surface is adapted to align the first part of a side member with the corner member; the positioning pin is adapted to connect by snapping with one of the positioning slots of the side member between i) a maximum length for each side of the frame by using an outermost positioning slot along the length of the side member on each side of the side member, and ii) a minimum length for each side of the frame by using an innermost positioning slot on each side of the side member to adjust to the size of the opening,-thereby forming a frame adjusted to the width and the height of the opening; the foldable tabs being adapted to fold inside the opening, behind the wall, ceiling or floor panel, and said distal end of said glide being aligned with said notch and adapted to engage said notch of the corner member to secure said door panel over said opening.
