Int. Cl. E06b 3/00 U.S. Cl. 49501 Claims ABSTRACT OF THE DISCLOSURE An integrally molded box locker door is described, for use either in substitution for steel doors in ordinary lock box construction, or for use in the original construction of lock boxes of synthetic plastic materials. A rectangular door face panel formed with a peripheral skirt defining a vertically-extending hinge side portion having a wall section of divergently increasing thickness, with respect to which hinge leaves are adapted to secured for hinging f r the door to a lock box opening, is described, whereby, due to the resilience of the skirt hinge side with respect to the face panel, spring action operative to prevent door slamming is effected.

This invention relates to box lockers, gymnasium lockers, wardrobe lockers and the like, and is directed particularly to an improved door construction for such lockers.

Various kinds of multiple-unit lockers are used in schools, gymnasiums, public institutions etc. for the personal storage of books, clothing, athletic equipment and the like. Since such lockers are ordinarily constructed of sheet steel, the unlocking and locking of the doors, and the closing of the doors, creates considerable noise. When a great number of such locker compartments are used at the same time, as commonly occurs in schools and gymnasiums, the resulting din can be most unpleasant and annoying. This is especially true in schools where lockers are located in hallways adjacent to classrooms in which classes are being held.

It is, accordingly, the principal object of this invention to provide an improved door for steel lockers that, for the most part, eliminates the noise associated with the opening and closing of locker doors.

A more particular object of the invention is to provide a new and improved locker door of the above nature including resilient means operative just prior to full closure of a locker compartment door that reacts in such a way as to substantially eliminate slamming of the door against the strike plate, or frame structure in which the door is hinged.

Another object of the invention is to provide a locker door of the character above described that can be readily molded or otherwise formed of tough synthetic plastic material.

Yet another object of the invention is to provide a locker door including a combination handle and padlock eye for use in association with an eye plate fixed with respect to the door frame for the insertion of a padlock, and which serves as a strike for the padlock to further minimize noise accompanying the locking and unlocking of a door.

Still another object of the invention is to provide an improved locker door of the character described that can be readily substituted for steel doors in ordinary steel locker construction, as well as being applicable to use in lockers constructed entirely of non-metal or synthetic materials.

Another object is to provide an improved locker door of the character described which will be simple in construction, economical to manufacture, easy to install, which can readily be manufactured in a wide variety of different colors for esthetic purposes and for purposes of identification, and which will be eflicient, quiet, and durable in use.

Other objects, features and advantages of the invention will be apparent from the following description when read with reference to the accompanying drawings. In the drawings, wherein like reference numerals denote corresponding parts throughout the several views:

FIG. 1 is a partial front elevational view of a typical steel box locker illustrating doors embodying the invention assembled thereto;

FIG. 2 is a rear elevational view of a locker door embodying the invention, shown separately;

FIG. 3 is a horizontal cross-sectional view, taken along the plane indicated at 3-3 in FIG. 1, on an enlarged scale;

FIG. 4 is a vertical cross-sectional view, taken alon the plaiie indicated at 4-4 in FIG. 1, on an enlarged scale; an

FIG. 5 is a perspective view, on an enlarged scale, of the upper hinge corner position of the locker door, illustrating constructional details thereof.

Referring now in detail to the drawings, reference numeral 10 designates, generally, an ordinary steel locker equipped with locker doors 10a embodying the invention. In order that the constructional and operational features of the present invention may be better understood, details of the locker door framework will first be described. As illustrated in FIGS. 1, 3 and 4, the locker framework 11 comprises a plurality of rectangular compartment door openings 12, each of which is formed with benTsheet metal header and sill portions 13 and 14, respectively, and laterally-spaced, vertically-extending jamb portions 15 and 16. As best illustrated in FIG. 3, the vertically-extending jamb portions 15 and 16 are bent to form co-extensive, right-angular, inwardly-extending

door strike portions

17 and 18, respectively.

Door hinges

19 and 20 are secured in spaced relation along the jamb portions 16 as by having one hinge leaf thereof received through an appropriate slot (not illustrated) in said jamb portion and welded, riveted or otherwise afiixed against the inside of the face of the sheet metal locker framework. In an alternative construction, the fixed hinge leaves could be secured flat against the outside of the jamb portion 16.

The locker door 10a embodying the invention is preferably integrally formed, such as by injection molding, of a tough thermo-plastic material, and comprises a rectangular outer face portion 22, having slightly rounded corners, and a peripheral skirt 23. The peripheral skirt 23 comprises identical upper and

lower skirt portions

24, 25 and opposed, vertically-extending hinge side skirt portion 26 and handle side skirt portion 27. The hinge side skirt portion 26 is integrally formed so that its outer wall is of gradually increasing thickness from the inside to the outside along its length, as is designated by reference numeral 28 in FIGS. 3 and 5, for the purpose hereinafter appearing. The outer surface of the hinge skirt portion 26 is also provided, in spaced relation along its length, with a pair of hinge leaf recesses 29 (see FIG. 5), each having a pair of vertically-spaced through openings 30. The outer face portion 22 of the locker door a is also provided with vertical slots 31 adjacent to the inner edge of and co-extensive with the hinge leaf recesses 29. The slots 31 provide openings for the reception of the knuckle portions of the door hinges 19, upon the door being assembled to the locker framework, as in hereinbelow more particularly described.

The handle side skirt portion 27 of the locker door 10a is convexly rounded at the outside along its length, as indicated at 32, for the purpose hereinafter described.

As illustrated in FIGS. 2, 3 and 4, the inside of the outer face portion 22 of the locker door 10a is integrally formed with

outstanding reinforcement ribs

33, 34 defining laterally-extending upper and lower rectangular enclosures. For additional strength and reinforcement of the door, the outer face portion 22 is also formed with interior, outwardly-extending pairs of laterally-spaced, triangle-defining

ribs

35, 36, and vertically-spaced,

triangledefining ribs

37 and 38. As means for strengthening the locker door in the vicinity of the hinge leaf recesses 29, the interior of the outer face portion 22 thereof is integrally formed with outstanding, elongated, shallow U- shaped ribs 39, 40 co-extensive with and in spaced parallel relation with respect to hinge leaf recesses 29, which define

hinge leaf slots

41, 42 respectively, to receive for assembly to the door, the free leaves of the

door hinges

19 and 20. For the purpose of additionally reforcing locker door 10a in the vicinity of

hinge leaf slots

41, 42, the inside of the outer face portion 22 thereof is further provided with

horizontal rib portions

43, 44 interconnecting rib 39 with

ribs

33 and 37, respectively, and horizontal n'b portions 45 and 46 interconnecting rib 40 with

ribs

38 and 34, respectively.

For ventilation purposes, the outer face portion 22 of the locker door 10a is integrally formed with an upper pair of vertically-spaced, horizontally-extending, outwardly-projecting

louvers

47, 48 and a lower pair of identical louvers 49, 59, all of which are provided along lower surface portions thereof with a plurality of laterallyspaced slot openings 51.

As is best illustrated in FIGS. 1 and 3, the outer face portion 22 of the locker door 10a is integrally formed along the handle side skirt portion 27, with a rounded, outwardly-extending handle 52 provided with a tapered, laterally-inwardly-extending boss portion 53. A central rounded recess 54 is provided in the handle portion 53 to provide access to a through opening 55 in handle portion 52 (see FIG. 3). When the door is closed as illustrated in FIG. 3, the handle opening 55 is in horizontal alignment with an opening 56 in an eye plate 57 extending outwardly of the locker framework.

In use, locker doors 10a embodying the invention can readily be assembled to an ordinary steel locker, such as described above, simply by inserting the free leaves of the

door hinges

19 and 20 within the

hinge leaf slots

41 and 42 and then applying fastening rivets (not illustrated) through openings in the door hinge skirt portion 26 and aligned openings in the respective hinge leaves and in slot ribs 39 and 40. When the door is so assembled, the knuckle portions of the

hinges

19 and 20 will be received partially within the slots 31, as best illustrated in FIGS. 1 and 3, and the door frame leaves of the hinges, upon closure of the door, will be received within the recesses 29. In this connection, it is to be noted that the hinges, if desired, could be preassembled to the doors embodying the present invention, to provide for fitting of the doors directly to the door openings of doorless box lockers.

The convexly rounded configuration along the length of the outer surface of the handle side skirt portion 27, as indicated as 32 in FIG. 3, not only provides for close fitting of the door to its door frame opening, but also provides for friction slide fit of the door along the adjacent door jamb to further enhance non-slamming operation of the door. The fabrication of the box locker door by injection molding techniques or the like permits ready rounding of the peripheral corners, which offer less of a hazard when the door is opened than ordinary steel doors heretofore manufactured and having sharp, square corners.
