Claims. (Cl. 160-96) The present invention relates broadly to door and door jamb assemblies, and in its more specific phases to a modified form of the so-called Dutch doors having upper and lowered hinged door sections which may be independently opened and closed.
Conventional house trailer door constructions involve the use of a one-piece thin panel main door for which a door jamb has to be built into the opening of the house trailer and, in addition, there is a separate full size thin panel screen door which fits the door jamb at the inner face of the door with such door jamb considerably thicker than the trailer wall to handle the two separately hinged doors. When the screen door is being used, it is common practice to fasten the outward opening main door in the fully opened position to the outer face of the house trailer.
In case of a sudden rain storm, it is then necessary for someone to go out doors to disengage the fastener holding the outer door at its latch edge, following which it can be closed. This is far from satisfactory since the person assuming this duty gets Wet in taking care of it. The fitting of a door and screen door in accordance with this practice also requires costly skilled help and normally several hours work to frame and fit the door and screen door. It was a recognition of such unsatisfactory condition of the house trailer door art and the complete lack of a thoroughly satisfactory solution to same which led to the conception and development of the present invention which, while intended primarily for house trailer use, is not restricted to same.
Accordingly among the objects of the present invention is the provision of a complete assembly of a mounting frame or door jamb, a hinged door frame, and sep arately hinged door panels fitting said door frame and fastenable to same, which assembly may be shipped as a unit from a factory and may be quickly and easily installed as a unit, thus saving a great deal of time, trouble, and labor and producing a better job than could be otherwise done.
The mounting frame or door jamb referred to above is a relatively rigid main frame to be secured to a wall in an opening such as a door opening in the latter; and the door frame referred to above is a unit construction hinged frame which fits into and closes against said mounting frame or door jamb. This door frame includes a horizontal frame member between its ends; an upper hinged door panel which is mounted between this horizontal frame member and the top member of the door frame; and a lower hinged door panel which is mounted between said horizontal frame member and the bottom member of said door frame. Hinge means unitarily unite the mounting frame or door jamb, the door frame, and the two door panels into a single unitary assembly which may be compactly packaged for shipment, and may be quickly and easily installed without highly skilled help. This assembly also preferably includes two hinged screens for the openings, which are normally closed by the hinged door panels, with the separate members of the whole assembly, except for the screens, mounted on a common set of hinges which thus avoids separate hinging operations.
Another object is to provide a strong and relatively light weight, durable, and rigid assembly, which may be made from hollow extruded aluminum alloy frame members, with the door much stronger than the ordinary house trailer door and with the door jamb of a thickness suitably matching the thickness of the wall at the opening into which it is to be framed, rather than too thick as is the case with the standard house trailer door and door jamb assembly on which is separately mounted both a door and screen door, and wherein means are provided for preventing moisture carried by warm air within the house trailer from condensing at least on part of the inner surface of the door jamb assembly.
Another object is to utilize the aforesaid horizontal frame member of the door frame for mounting the door latch which may be in the form of an ordinary door lock having a bevel-ended spring-projected bolt, knobs, and other conventional parts, thus simplifying the construction.
Another object is to provide releasable means for holding either or both door panels, which are of sash-like form with marginal frames, fully open adjacent the outer side of the trailer wall or the like in hot weather with the door frame movable independently of said panels, said means being readily accessible from the inside of the trailer by simply swinging the screens inwardly. Thus, in case of sudden rain, the door panels may be quickly closed without going outside.
Still further objects and advantages of the present invention will appear as the description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, consists of the door and door jamb assembly hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be used.
In the accompanying drawings:
Figure 1 is an outer side elevation of the assembly with the door frame and both door panels closed.
Figure 2 is an upper end view of the assembly installed, the upper door panel being held in extreme open position at the outer side of the Wall, the door frame being open, and the upper screen being dotted in partly open position.
Figure 3 is a vertical sectional view taken on line 3-3 of Figure 1, looking in the direction of the arrows.
Figure 4 is an enlarged fragmentary detail horizontal sectional view taken on line 44 of Figure 1, looking in the direction of the arrows.
A practicable construction of the door and door jamb assembly has been disclosed in the drawings, and while that construction will now be rather specifically described, it is to be understood that varitions may be made within the spirit and scope of the invention as thus set forth. Referring more particularly to the drawings, the mounting frame or door jamb is generally designated at 5, the door frame at 6, the upper door panel at 7, the lower door panel at 8, the hinges at 9, and the screens at 10.
The mounting frame 5 has vertical side members or iambs 11 and 12., a top member 13, and a bottom member or threshold 14, all of said members being suitably joined in conventional manner at the corners of the frame, and all having flanges 15 to be secured against a wall 16 when the frame 5 is inserted into the opening 17 of said wall. The flanges 15 are preferably provided with recesses 47, Figure 3, to carry a suitable gasket, such as a tubular gasket 48 of the type shown in gasket carrying flanges 18a, Figure 4, for sealing engagement with the wall 16. The members 11, 12, 13, and 14 each have a set-back shoulder 18 against which the door frame 6 is closable.
The door frame 6 comprises vertical side members 19 and 20, a top member 21, a bottom member 22, and a horizontal member 23 between said top and bottom members. This member 23, Figure 3, includes an upper horizontal bar 24, and a lower horizontal bar 25, both suitably securcd at their ends to the door frame vertical members 19 and 20, respectively. Between these bars 24, 25. there are an outer plate 26 and an inner plate 27 disposed in parallel vertical planes. The horizontal edges of the plates 26 and 27 are suitably held by the bars 24, 25 and the ends of said plates abut the members 19, 20, as will be clear from Figures 1, 3, and 4.
All of the frame elements 19, 20, 21, 22, 24, and 25 each have an outer set-back shoulder 28 and an inner setback shoulder 29 against which the door panels 7 and 8 are closable. The elements 19 to 22 have gasket-carrying flanges 18a which coact with the set-back shoulders 18 of the mounting frame or door jamb 6.
The upper door panel 7 is of sash-like form, being provided with a marginal frame 30, and a window glass 3]., supported thereon in conventional manner such as by means of a rubber gasket 49. The lower door panel 8 is also of. sash-like form, but normally has opaque panels 32 held in any convenient manner by its marginal frame 33. The side and end members of the frames 30 and 33 close against the inner set-back shoulders 29 of the door frame 7 and are provided with gasket-carrying flanges 34, similar to flanges 18a of the door frame, which close against the outer set-back shoulders 28.
Suitable latches 35, one form of which is shown in Figure 2, are provided to lock the door panels 7 and 8 in closed position, and any suitable latch such as a conventional tubular lock 36 is mounted in the hollow frame member 23 of the door frame 6 for holding the latter closed. This lock has conventional knobs 37 and a beveled spring-pressed bolt 38, the latter being engageable with an opening 39 in the jamb 12 of the mounting frame or door jamb 5, which opening functions the same as a suitable keeper or strike-plate.
The frames of the screens 10 are preferably hinged at one edge by means of vertical studs 40 (dotted in Figure 3) to door frame 6, and said screens may be held closed by suitable releasable means such as turn-buttons, one of which is indicated at 41 in Figure 2.
Any suitable holding means, such as a spring catch 42, Figure 2, is provided on the ball 16 for holding the door panels 7 and 8 in extreme open positions adjacent the outer side of said wall, when desired. By swinging the screens 10 inwardly out of the way, a person within the trailer or the like may reach through the door frame 6 and release the catch 42, thus allowing the door panels 7 and 8 to be pulled shut in case of sudden rain, or at night. without having to go out doors.
Each hinge 9, Figures 1 and 3, has three leaves 43, 44, 45 connected by a single hinge pin 50. The leaves 43 are secured to the jamb 11 of the mounting frame or door jamb 5; the leaves 44 are secured to the door frame 6; and the leaves 45 are secured two to the door panel 7 and two to the door panel 8. This allows either or both of the door panels 7 and 8 to be fastened open while allowing the door frame 6 to be moved independently, door fashion, without shifting the position of either of the door panels 7 or 8.
The element 46 in Figures 2, 3, and 4 is a strip of thermal insulation of any suitable material, such as wood or plastic, which prevents warm air in the trailer or the like from freely contacting with the inner edge of the mounting frame 5 and condensing thereon when said frame is relatively cold. While this strip, for convenience of illustration in Figure 3, is shown only on the top member 13 of frame 5, similar strips are preferably secured to the jambs 11 and 12, as shown in Figure 4. The strips, when extended over the edge of the door, would W desired. The directional terms such as inner,
then act also as inner stops for the hinged door frame 6.
From the foregoing it will be seen that a novel structure for a door and door jamb assembly has been disclosed for attaining the desired ends, but attention is again invited to the possibility of making variations without departing from the spirit and scope of the invention as set forth. While, for convenience, the apparatus has been shown in its normal upright position, it is not limited to that position since it can be operated in other positions if outer," upper, lower, top, and bottom, are accordingly to be considered as relative only, and not limiting on the construction involved.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the article and combinations herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
