A deformable ladder is disclosed and claimed for patent protection in U.S. Pat. Each of these ladders consists of U-shaped frames connected to each other by hinges that allow each frame to be folded or slid into an adjacent wide frame when not in use. Each of these ladders has a locking mechanism that allows each frame to be reliably locked when the ladder is in the extended or raised position.

In all of the above patent applications, except US Patent Application No. 06/417.382, a U-shaped pivoted frame is used which is compacted and folded into an adjacent wider frame for storage or transportation. Each pivoted frame can rotate 360 degrees around its axis, so
It can be transformed into a stepladder, workbench, etc. in various ways. No. 06/537.276 discloses a modification of the ladder to the workbench and is illustrated in FIG. 6 of the drawings of that application. This workbench can be formed from a folding ladder by simply folding the second (from the bottom) and fifth (from the bottom) frames. These frames are then locked into place,
It is supported by brackets 32 at least at two corners. These brackets generally take the form of metal or plastic rods with a protrusion at one end and an opening at the other end. If this structure is used as a workbench, it is highly desirable to have a work surface on which to work.

DESCRIPTION OF THE DRAWINGS AND PREFERRED EMBODIMENTS OF THE INVENTION FIG. 1 is a top perspective view of a table top plate or workbench top plate 1. FIG. The top plate is substantially rectangular and has an extension 2 of a width no wider than the width of the main rectangular structure 3. The top plate 1 has a top part 4 and a side wall having approximately the same height all around the outer edge of the top plate 1.
It has a knob 5. These side walls 5 provide a tight fitting encirclement around the rails 6 of the support structure or workbench 7.

The dimensions of the main rectangular portion of the removable top plate 1 are slightly larger than the dimensions of the upper outer portion of the workbench 7. In the extension 2 of the top 1 is located a recessed pocket 8 which can be used for screws, nails, bolts, tools and other items needed when working with the workbench 7. The extension portion 2 may have any external shape, but preferably has a rectangular shape so that it fits snugly between the rails 9 as shown in FIG.

In FIG. 2, the table top plate 1 has been inverted to show the bottom part as a bottom perspective view. The wall 5 completely surrounds the outer edge of the table top 1 and its tight fit on all four sides ensures that the table top 1 is held in place. The cutout portion 10 allows the table top plate 1 to be firmly fitted around the rail 9 and the bracket 11.

The notch 10 is located between the end of the extension part 2 and the recess 1 of the table top plate 1.
Located close to 2. The bottom surface 13 of the pocket 8 serves two functions. First, the article is held in the pocket 8 and one side of the storage chamber 14 for the bracket is formed.

When the bracket 11 is not in use, it is stored in the storage chamber 14 (as shown in FIG. 5).

The bottom inner surface 15 of the wall 5 is connected to the legs 16 of the ladder or workbench 7.
and firmly fit together. This bottom inner wall 15 is preferably grooved as shown in the drawings to ensure that the legs 16 are held in place. Also, as shown in FIG. 5, it is preferable to locate a protrusion or nipple 17 on the bottom surface of the table top plate 1 in order to better support the ladder when in the stowed configuration. When the ladder or workbench 7 is stored in the top plate 1, the protrusion 17 contacts the rail or rack 18 to hold it fixedly. The groove part 20 is located on the bottom side of the top plate 1, and accommodates the legs of a ladder or support part when it is in a folded or stored form and when it is stored during transportation or storage.

In FIG. 3, the ladder 7 is shown transformed into a workbench or table 7. The brackets 1-11 are located at diagonal corners for optimal support. However, they can be used at all four corners if desired. The side rails 6 around which the table top plate l of the invention fits constitute the external longitudinal framework of the top surface of the worktable top plate. Accordingly, the table top plate 1 fits around the top of the rack 19 with the side rails 6 forming the contour of the top structure of the workbench 7.

FIG. 4 shows a workbench 7 on which the table top plate 1 of the present invention is attached. The side wall 5 is a case 1 forming the upper surface of the workbench 7.
9 and the side rails 6 completely and rigidly. Due to the secure fit, the table top plate 1 is firmly held in place and does not slip.

Further safety is provided by cutouts 10 that fit around the brackets 11 and/or side rails to lock the table top plate 1 in place. The bokeh 8 is shown positioned within the extension 2 to fit between the narrow side rails 9. Bracket 11 is clearly shown in place at a diagonal corner of workbench 7.

FIG. 5 shows the ladder or rung when the rails and rungs (which constitute the frame 21 of the ladder or support structure of the invention) are folded and placed within the tabletop 1 for storage 2 transportation and protection. A workbench 7 is shown. The bracket II is housed in the upper storage chamber 14 and is in contact with the upper side wall of the pocket.

The ladder 7 abuts the lower side wall of the pocket and is held firmly in place at the same location and at other locations around its outer edge. The legs 16 are firmly in contact with the inner wall 5 of the table top plate 1, and since the table top plate 1 is made of a material having some degree of elasticity (preferably polystyrene material), a spring-like locking action is performed. When folded in this way, the ladder 7 is firmly fitted into the table top plate 1,
The elasticity of the table top plate l firmly grips the ladder and holds it in place.

When the table top plate is made of metal, the elastic locking effect is slightly reduced, but the rubber end portions of the legs 16 ensure a certain degree of elastic locking effect.

The rail 18 or the case 18 fits over both protrusions 17,
To prevent the ladder from slipping during transportation, a holding operation is performed. It is preferable that the table top plate 1 has at least one protrusion or arbitrary-shaped structure located on the bottom surface and extending downward from the bottom surface. This is removable. It can be in the shape of a bar extending across part or the entire width of the table top plate 1.

Furthermore, the protrusions and the like can be integrated with the table top plate 1, or can be detachably attached thereto. In this way, it can be instantly attached to the bottom surface of the table top plate 1Φ when necessary for operation, etc., and can be removed when in use.

Additionally, a platform top plate similar to that described above can be used when using a ladder or support structure as shown in FIG. 3B of co-pending US patent application Ser. No. 600,804. This means that when one frame of the ladder is folded, the ledge becomes the working surface of the ladder.

Brackets 11 are used to support this working surface formed by the folded frame. The platform top plate is simply mounted on the folded frame to provide a surface on which paint cans, tools, and other items can be placed. The workbench top plate may include a paint roller brush, pad, etc., as well as a recessed pocket into which the paint being used is poured. This pocket can be provided with vertical or sloped walls for storing used rollers and pads. The platform top plate can be provided with additional strength by fitting into a recess in the frame or by fitting side rails of the frame.

While the preferred and most preferred embodiments of the invention have been described and the basic concepts of the invention have been illustrated in the accompanying drawings, it will be understood that many changes can be made without departing from the spirit and scope of the invention. .
