7 Claims. (Cl. 189-46) This invention relates to metal doors and particularly to doors the center panels of which are made of glass, fiberboard or other preferred sheet material.

In metal doors of this character as made prior to my invention, the center panel is held in position in the frame between opposed glazing beads or stops, one of which is formed integral with the" frame on one face of the door and the other of which is removable and held in position by screws or the like on the other face of the door. The removable bead or stop must, of course, be located on the inner face of the door where access to it cannot be had by intruders. Since the glazing stop which is integral with the door frame on one face of the door is formed during the fabrication of the door, the door consequently be-- comes identified before shipment as a right-hand swing in or left-hand swing out door, or as a left-hand swing in or right-hand swing out door. Unless thus mounted with the permanent integral glazing stop on the outside, the removable glazing stops, it disposed on the outer face of the door, will be accessible for unauthorized removal to afford illegal entry through the door.

It will be apparent, therefore, that since neither a distributor nor a dealer can anticipate whether demand will be predominantly for right-hand or left-hand'swingor swing out doors, they are obliged either to stock both types in substantial numbers, many of which: will inevita-' bly constitute stagnant inventory, or to have their re"- quirements for each customer made to order. The latter alternative, which is at present the customary practice, results in prolonged and vexatious delays in delivery.

The primary purpose of my present invention isytdpro-I vide av standard metal door which may be warehoused and stocked in quantities and sold to behung and used as either a right or a left-hand swing door without'ex posing the removable glazing stops on the outer face of the door. To this end the panel structure including. the panel proper is reversible in the frame,v thereby enabling the removable glazing stops to be disposed on the inside face of the door irrespective of whether the door be hung" as a right-hand-or a left-hand swingdoon.

A more specific object is to provide a door in which the glazing stops, instead of being mounted on thefrarfle of the door, are mounted on a detachable molding which can be removed from and reversedin'thefra'me- A further object is the provision of molding. strips or members which may be readily detached from and reversedrelatively to the door frame in which the reversible panelv is carried;

A still further object is to provide a reversible panel structure, the principles of which may be employed in connection with the different types of metal doors known respectively as industrial doors and hollow metal doors, thereby enabling both types to be made in standard form and equipped with reversible panel structures.

When the reversible panel structure'comprises aplurah ity of panes or panel members withinterposed muntin bars, my invention" contemplates the provision of novel means for detachably securing the removable muntin United States Patent ice 2,747,705 Patented May 29,

2 bars in position, thereby enabling their removal and reversal in the door.

Another feature of my invention resides in the provision of novel means for detachably securing the vertical mun'tin bars to the horizontal nnintin bar and to the detach'able molding so that they' r'na'y be readily detached and reassembled.

Still another feature of my ihvention resides in the provision of means for locking the detachable molding to the door frame so that the molding will be securely held in assembled relation to the frame.

Other objects and inherent advantages of my inventionwill be better a preciated as the same becomes further understood by reference to thefollowing description when considered in connection with the accompanying drawings.

The door,- iii this instance, is hinged at the left side is known" as a left-hand swing out door. It comprises the: frontupright stile 16, the rear upright stile 17, the marsh-18, a center rail 1-9 and a bottom rail (nctshcvvn).

Within the door frame formed by the stiles a d' the connecting cross rails is moiinted' the detachable and reversible panel structure comprising the upper and lower

molding strips ormembers

21 and 22, the transverse muntinbar 23, the-upper and lower niuntin bars 24 and 25', respectively, and the glass panels designated collectively by reference character 26.

By reference to Fig. 2, it will be observed that the ing roove 28. These rooves are designed tc'rece'ive the resilie'nt 'legs Z9 a'iid Bi -of the molding strips 21' and 22, respectively, whereby these strips are detachably connected to and carried by their respective cross-rails 18 i and 19. The

moldings

21 and 22 are shaped, as will be apparent from Fig. 2, to provide an abutment or

shoulder

32 and 33, respectively, against which the upper and lower margins of the outer faces of glass or other preferred material panels 26 abut when the panels are in assembled position.

The transverse muntin bar 23 which is substantially T-shaped in cross section and of hollow metal construc tion, as shown in Figs. 3 and 8, is provided in the base wall of the T with a longitudinally extending slot having inturned edges 30 to receive and engage a series of glazing stop fastening screws to be later described. This muntin bar is detachably connected to the

stiles

16 and 17 of the door by tenons, one at least of which is slidably mounted in the bar in proximity to an end thereof. As shown in Figs. 7, 8, and 9 of the drawings, such tenon consists of a base 34 slidable in the head of the muntin bar and a tenon portion 35 projecting from one end of the base and reversely bent so as to provide a tenon adapted to be projected beyond the end of the muntin bar into the groove 36 of the stile 17. The free end 37 of the tenon is provided with a tapped opening 38 through which projects a machine screw 39. This screw extends upwardly through a slot 41 so that its head is accessible for engagement by a screw driver at the inner side of the door. A similar adjustable tenon or a tenon integral with the muntin bar at the opposite end of the bar is detachably engageable with a groove in stile 16 similar to the groove 36 in stile 17.

When the muntin bar is to be mounted in the door between the stiles, it is placed in approximately the vertical position desired with one tenon engaged in the frame groove, whereupon the adjustable clip or tenon at the other end of the bar is projected longitudinally from the end of the mutin bar into the aligned groove of the stile adapted to receive it. This sliding movement of the tenon or tenons may be effected with a screw driver or a light hammer, the screw 39 being free to move with the tenon longitudinally of the slot 41. The bar may be accurately positioned by tapping it lightly with a hammer to move it upwardly or downwardly with respect to the stiles, and when properly positioned is locked against movement by threading the screw 39 into the bar which is shaped to accommodate the head of the screw at each side of the slot 41, as shown in Fig. 8. When the end of the screw engages the base 34 of the tenon, the free end 37 of the tenon is forced away from the base, thus expanding the tenon in the groove of the stile so that its upturned edges are forced into firm engagement with the sides of the groove 36, thereby locking the muntin bar in its adjusted position.

The panel may consist of one, two or four glass panes. In Fig. 1 a four pane panel is illustrated. In the event a single pane panel is employed, the horizontal and vertical muntin bars are, of course, dispensed with and the panel is mounted by sliding one vertical margin into the groove of one stile until the opposite edge of the panel clears the inner edge of the opposite stile, whereupon the panel may be aligned with the groove in that stile and then shifted laterally into that groove so that both vertical margins are disposed in the stile grooves. The position of a panel extending partially into a stile groove 36 is illustrated in the broken-away fragment in Fig. l.

When a two pane panel is employed, the horizontal muntin bar 23 is required, which is positioned and locked in the stile grooves by means of the slidable locking tenons 35 previously described. Preferably each end of the muntin bar is equipped with one of these adjustable tenons.

Should a four pane panel, such as is shown in Fig. 1, be desired, the

vertical muntin bars

24 and 25 are also necessary. These muntin bars are detachably mounted in position by means of slidable locking members 42 shaped as shown in Figs. 4 and and slidably mounted 4 within the

muntin bars

24 and 25. The wings 43 of the locking members are shaped to frictionally engage the interior of the muntin bar and since they are formed of resilient sheet metal they serve to hold the locking members in longitudinally adjusted position.

In assembling the munting bars in the panel structure, the bars with the members 42 inside are placed in position, whereupon these members are projected longitudinally outwardly beyond the ends of the bars so that one of the channel-shaped ends 44 may be secured by a screw 40 to the muntin bar 23 and the other may be similarly secured to one of the

moldings

21 or 22. The members 42 accordingly serve to detachably connect the vertical muntin bars 24 and 25 to the molding and to the cross muntin bar.

When the removable panel formed by one or more panes is placed in position between the molding strip 21 and the transverse muntin bar 23, it is locked in position at the top by a glazing stop 45 mounted on the molding 21 by means of screws 46 and its lower edge is similarly held by the glazing stop 47 removably mounted on the muntin bar 23 by means of holding screws 48, all as illustrated in Fig. 2. Putty or similar sealing material may be employed along the stiles to hold the pane or panes against horizontal movement in the frame.

In the fabrication of these doors the frames consisting of the stiles and cross rails are assembled at the factory, and the panel structure comprising the detachable molding strips, the removable glazing stops and the panels, whether single pane or multiple pane, together with the necessary muntin bars, is packaged separately and assembled on the job in the frame. The door may be assembled to serve as a right-hand or a left-hand swing door at will by assembling the detachable molding strips in the frame so that the abutment shoulder 32 faces toward the inside of the room or building structure, thereby locating the removable glazing stops 45 on the inner face of the door. If the door is to be used in a reverse hand mounting, the detachable molding strips will be assembled in the frame so as to face in the opposite direction. By making the detachable molding strips reversible so that they may be assembled in the frame to face in either direction desired, I am enabled to provide astandard metal door made of standard parts capable of being assembled on the job to meet the requirements both as to hand and swing in every instance.

In the form of construction shown in Figs. 1 and 2, the detachable molding strips 21 and 22 are employed only at the top and bottom of the panel, the side margins of the panel being set into the grooves in the stiles as previously explained. It is possible, however, to employ the detachable moldings at the sides instead of the top and bottom and such use is illustrated in Fig. 14, wherein the detachable molding strips designated by reference character 49 are mounted in the

stiles

16 and 17. The glazing bead stops 51 as well as the molding are shaped somewhat dilferently from the stops and molding shown in Fig. 2, but the holding function and the removability are the same as the structure shown in Fig. 2. In this instance the screws 52 by which the glazing stops are mounted on the molding are disposed diagonally instead of parallel with the plane of the panel. Similarly shaped moldings are shown in Figs. 10 and 13, and in Fig. 13 the glazing stop 51 is similarly held by diagonally disposed screws 52.

In order to insure against accidental displacement of the detachable molding during assembly of the structure or before the panel is positioned in the frame, and in order to lend rigidity to the structure, my invention contemplates means for locking the molding to the rail, which is illustrated in Figs. 10l3, inclusive.

Referring to Fig. 10, it will be observed that in this instance the rail, which may be either

rail

18 or 19 of Fig. 2, instead of being provided with a groove having parallel side walls like

grooves

27 and 28 of Fig. 2, is provided with a groove 53 having do "nwardly diverging side walls. The legs 54 of the molding 49 are adapted to be spread to conform to such diverging side walls. For the purpose of spreading them and holding them in spread interlocking relation with the side walls, a pin or locking member 55 is provided which, as shown best in Fig. 12, is provided on opposed sides with grooves or notches 56 near one end. The opposite end is provided with a head 57 of elongated contour by which the pin may be rotated through a quarter turn to bring the notches 56 into engagement with the lower converging ends of the legs 55. This engagement of the ends of the legs in the notches 56 locks the pin 55 in position to hold the legs 54 in locking relation with the diverging walls of the groove 53.

In Fig. 13 the locking pin is shown as employed with a groove having parallel side walls. Of course, the locking effect in this instance is not as great as with the diverging side wall groove of Fig. 10. Nevertheless, the legs of the molding are spread sufficiently to provide a strong friction connection of the molding to the rail.

The industrial door which has been thus far described is, as previously stated, designed to employ detachable molding strips only on two opposed sides or ends of the panel opening in the frame. The hollow metal door previously mentioned and shown in Figs. ll8, inclusive, of the drawings contemplates the employment of detachable molding strips entirely around the panel receiving opening in the frame. In this instance, the

stiles

16 and 17 and the end rail 18 are provided with grooves 27 for the reception of the legs of the detachable molding strips 53, 54 and 55. The center cross rail 56, however, is not provided with a molding receiving groove, as will be evident from Fig. 18.

The molding strip 57 is detachably mounted on the rail 56 so that it may be removed and reversed, but since provision must be made which will enable this strip to be slid laterally into position, it is retained in position by screws 58. The glazing stop 59 is similar to although not identical in form with the stops previously described.

In mounting the panel in the hollow metal door of this type the detachable molding strip 55 is first positioned in top rail 13. The vertical molding strips 53 and 54 are then consecutively connected to their respective stiles by first inserting their mitered upper ends into the space at the mitered ends of the strip 55, whereupon the vertical strips may be swung about their upper ends as the pivot to project the legs of the strips into the stile grooves, thereby attaching the molding strips to the stiles. The center rail strip 57, the ends of which are also mitered as shown, is then slid sideways onto the center rail so that it is disposed in alignment with the molding strips 53, 54 and 55, whereupon it is secured in its required position by means of screws 58. The four strips thereby form a continuous molding for the reception of the panel proper which is then secured in position by the glazing stops in the usual manner.

It will be apparent from the foregoing that I have provided a door having a reversible panel structure comprising one or more panel panes which can be mounted in the frame so as to dispose the glazing bead stops on the inner face of the door, irrespective of whether the door be hung as a right-hand or left-hand swing door. By providing for reversibility, standard reversible doors may be carried in stock and mounted either as a right-hand or left-hand swing door. Considerable expense over stocking both right and left-hand swing doos and a substantial saving in time of delivery are thereby attained.

The structural details illustrated and described may obviously be varied within considerable limits without departing from the essence of my invention as defined in the following claims.
