DETAILED DESCRIPTION OF THE DRAWINGS
(6) FIG. 1 is a detailed exploded view of the preferred embodiment of the present invention which includes a protector unit 1 for a sliding door frame 2. The sliding door frame 2 consists of a sill plate 3 and a sill riser 4. The sill plate 3 is attached to the door entryway and has a plurality of tracks 5 for supporting the rollers at the base of the sliding doors. The number of tracks 5 would be equal to the number of sliding doors plus screen doors for a particular building arrangement. A channel space 6 is provided on either side of the tracks 5 for passage of the sliding doors. For example, if there were three sliding doors then there would be three tracks and four channel spaces. This is well known in the construction trades and is not considered part of the present invention. The sill riser 4 abuts the sill plate 3 and extends parallel thereto. The height of the sill riser 4 is driven by the design pressure measured in pounds per square foot of wind pressure on the sliding door assembly. During construction of a building, the sliding door frame 2 is installed between the supporting walls of a building. The sliding door frame 2 is exposed to damage by the mere moving of equipment in and out of the building through the entryway. The protector unit 1 of the present invention provides for a sill riser cover 7 and a sill plate cover 8 which are fastened together by connection means 9. The sill riser cover 7 is shown as an modified inverted U-shaped flexible member made of a rubberized plastic, cardboard or vinyl material which can be either molded or extruded and can be about .sup.th of an inch thick. The sill plate cover 8 is flat planar flexible member having an upper surface 8a and a lower surface 8b which extends horizontally over the sill plate 3 and can be made of a rubberized plastic, cardboard or vinyl material which can be either molded or extruded and can be about of an inch thick. A plurality of channel members 10 extend from said lower surface 8b of the sill plate cover 8 and are seated within the channel spaces 6 between the tracks 5 which give stability to the sill plate cover 8.
(7) FIG. 2 is a sectional view of the connection means 9 showing the detail of the sill riser cover 7 having a first leg 7a and a second leg 7b with the first leg 7a having an extension edge 12 capable of mating with a slot 13 on the upper surface 8a of the sill plate cover 8. The extension edge 12 has a plurality of splines 14 positioned thereon to insure a rigid snap fit into the slot 13. The second leg 7b has a plurality of score marks 11a and 11b positioned vertically thereon which can be easily cut when the carpet pad, carpet, wood flooring are laid. For example, once the carpet and carpet pad were installed, the sill riser cover 7 would be cut at score mark 11a. If wood flooring was laid then the sill riser cover 7 would be cut at score mark 11b.
(8) FIG. 3 is a sectional view of the connection means 9 showing the detail of the sill riser cover 7 having a first leg 7a and a second leg 7b and wherein the first leg 7a having a recess 16 which can easily mate with a finger 15 extending upwardly from the upper surface 8a of sill plate cover 8. The finger 15 can have a plurality of splines 17 thereon to insure a rigid snap fit into the recess 16 within the sill riser cover 7. For example, once the carpet and carpet pad were installed, the sill riser cover 7 would be cut at score mark 11a. If wood flooring was laid then the sill riser cover 7 would be cut at score mark 11b.
(9) FIG. 4 is a sectional view of the connection means 9 including the sill riser cover 7 having a first leg 7a and a second leg 7b. The first leg 7a is inserted into the groove 20 defined by a pair of walls extending upwardly from the upper surface 8a of the sill plate cover 8 and a second leg 7b positioned on the room side of the sill riser 4. For example, once the carpet and carpet pad were installed, the sill riser cover 7 would be cut at score mark 11a. If wood flooring was laid then the sill riser cover 7 would be cut at score mark 11b.
(10) FIG. 5 is a sectional view of the sill plate cover 8 having a plurality of channel members 10 extending from the lower surface 8b thereof. An additional segment 18 is provided with additional channel members 19 extending from the lower surface 18b and having a protuberance 21 capable of mating with opening 22 on the channel member 10. It is contemplated that this design could take on many different alternatives; for example, the opening 22 on channel member 10 could run the entire length thereof with the protuberance 21 running the entire length of the additional channel member 19. Openings 22 could be designed as a plurality of openings spaced along the channel member 10. Of course the protuberance 21 would be designed accordingly to mate the channel member 10 with the additional channel member 19. As another alternative, the protuberance 21 could extend from the channel member 10 with the openings 22 formed in the additional channel member 19.
