Description
~- 2 99 1 ~8 TITLE: DOOR PANEL FRAME HAVING PLASTIC COVERED INTERNAL
REINFORCEMENT
FIELD OF THE INVENTION
The present invention relates to a panel frame around and securing a door panel to a door frame. The panel frame is formed from an internal reinforcing member with a plastic cover over the reinforcing member.
BACKGROUND OF THE INVENTION
Many of today's most up to date window and door assemblies are made from plastic material such as vinyl and the like. These plastic materials have advantages over conventional wood and all aluminum constructions in that the plastic is extremely durable and it can be treated with essentially permanent finishes.
It is not however practical to have a solid plastic window or door frame so that they are therefore made with a hollow construction. In some setups such as that required for an entrance door, a hollow plastic construction of the frame requires interior stiffeners to reinforce the strength of the frame.
It is known for instance to form a door panel frame, i.e. the frame portion between the actual panel and the frame of the door with a hollow plastic construction and steel reinforcing members within the panel frame. In the past, this type of construction has been made by first forming tubular plastic jamb, header and sill frame components, inserting steel reinforcing members into the frame components and then welding the plastic frame components to one another.
Although the construction described immediately above does end up with an internal steel and exterior ~ _ 2! q91 9P~
plastic construction, the steel reinforcing members because they are fitted individually into the plastic cover portions, cannot be rigidly connected to one another. This allows unwanted play within the door panel frame.
United States Patent 4,993,204 describes a door panel frame in which reinforcing members are secured by mechanical fasteners interiorly of a plastic cover.
According to the above patent, the header, jambs and sill of the plastic cover which are open on their exterior sides are all welded to one another. The interior reinforcing member is formed into a U-shape by leaving either the header or the sill portion off and then the U-shaped reinforcing member is slid into the plastic cover. At this point, the final leg of the reinforcing member is secured by further mechanical fasteners and final cover pieces are then added to the plastic cover to complete the construction.
The above method of fitting the reinforcing member with the plastic is better than what is generally known in the art but it still suffers from the drawback that the interior reinforcing member cannot be given a complete continuous formation prior to covering and it is not possible to have a fully welded construction of a steel insert within a plastic cover. In addition, there is a requirement for welding or otherwise securing the jambs, header and sill of the plastic cover to one another before fitting of the reinforcing insert.
SUMMARY OF THE INVENTION
The present invention provides a door panel frame having an interior reinforcing member and a plastic cover over the reinforcing member. The reinforcing member is formed by a pair of side jambs rigidly secured at their opposite ends to a header and a sill. The cover comprises '' 21q91q~
a plurality of interlocking cover pieces which are introduced to one another from opposite sides of the reinforcing member thereby allowing complete formation of the reinforcing member prior to covering.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION
Figure 1 shows a door assembly generally indicated at 1. This door assembly comprises a door frame 3 which is mounted directly to the building wall. A door panel 11 is mounted to the door frame 3 by means of a panel frame 5.
SJ-9609 _ 4 _ The panel frame is secured by hinges 7 to one side of the door frame 3 with a door knob activated latch 9 on the other side of the assembly. A latch plate 10 is provided in the door frame to receive latch 9.
Panel 11 can be made in many different ways, as for example with a steel or a wood construction. It could also have a reinforced plastic construction.
The present invention relates more to the door panel frame 5 and the door frame 3.
Figure 2 shows one of the key features of the present invention in which a door panel frame 5 is formed with an interior reinforcing member generally indicated at 13 and covered by a series of plastic and preferably vinyl covering pieces which interlock with one another over the reinforcing member. The preferred method of interlocking the cover pieces is by snap connecting them to one another.
This will be described later in detail. Once all the covering pieces have been fitted in place, the plastic is welded or otherwise given a completed finish look at the four corners of the plastic frame.
The interior reinforcing member is preferably made from hollow tubular steel with jambs 17 and 18 being welded at their opposite ends to a header 15 and a sill 19 of the reinforcing member. As shown in Figure 2, the reinforcing member has a complete continuous formation prior to being covered.
The plastic cover is as earlier described formed from a series of plastic pieces namely pieces 21, 41, 51, 57, 65 and 67.
Cover pieces 21 are fitted to one side of the metal insert and reach across the inside of the insert to 2 ! 99 1 98 SJ-9609 _ 5 _ interlock with cover pieces 41 on the other side of the insert. Cover pieces 51 and 57 interlock with the cover pieces 21 and 41 on opposite outside edges of the metal insert while cover pieces 65 and 67 which also interlock with the cover pieces 21 and 41 cover the top and bottom edges of the metal insert.
Figures 3, 4 and 5 show, in detail, the respective cover pieces 21 and 41. It will be seen that each of these cover pieces as well as the other cover pieces have a multiple wall hollow chambered construction. In particular, cover piece 21 is formed by an outside wall 23 separated from an inside wall 25 by a plurality of spanning ribs 27 to define hollow chambers 31 within the cover piece. These chambers provide a condensation passage through the plastic frame outwardly around the metal insert. The ribs 27 are extended by rib extensions 29 which engage the metal insert. Similar rib extensions are provided on all of the other cover pieces as well.
Cover piece 21 includes an arm portion 35 at generally right angles to and at one end of the main body of cover portion 21. Arm 35 terminates with an arrow shaped head 37. The other end of the arm is provided with an open mouth region 39.
The other end of the main body of cover portion 21 away from arm 35 is provided with a barbed mouth 33.
As will be seen in Figure 3, the arm 35 of cover portion 21 substantially spans the thickness of the door panel 11 to reach across to cover portion 41. This particular cover portion is provided with a barbed mouth 45 to snap fit with the head 37 of the arm 35 of cover portion 21.
The other end of cover portion 41 is provided with a second barbed mouth 43. Plastic cover portion 51 is provided at its opposite ends with arrow shaped heads 53 and 55 which snap lock into mouth 43 of cover portion 41 and mouth 33 of cover portion 21 to complete the assembly of the jamb of the cover portion around the jamb 18 of the internal reinforcing member 13.
The only difference on the other side of the door panel frame for wrapping the plastic cover around the jamb 17 of the reinforcing member 13, is that cover portion 51 described immediately above is replaced with cover portion 57. This particular cover portion includes arrow shaped heads 59 and 61 which snap lock into the barbed mouths 43 and 33 of cover portions 41 and 21 respectively.
Cover portion 57 includes a central channel 63 which as well shown in Figure 4 of the drawings accommodates the fitting of the door latch 9 through the cover portion 57.
The actual securing of the door panel with the panel frame is provided by a glazing bead 47 integral with plastic cover piece 41 to the outside of the door and a releasable glazing bead 48 which interlocks with plastic cover piece 21 to the inside of the door. The door panel is clamped between these two glazing beads.
Figure 6 of the drawings shows that glazing bead 48 includes an arm portion 49 which fits into the open mouth 39 of the arm 35 of cover portion 21. Mouth 39 is provided to one side with a small catch 40 which releasably interlocks with a small catch 50 on the glazing bead 48.
These two catches have oppositely directed cam faces which allow them to slide over one another as the arm 49 of glazing bead 48 slides into mouth 39. The pressure applied 2 1 9~ 1 98 SJ-9609 - 7 _ on glazing bead 48 by the door panel forces the two catches 40 and 50 to effectively interlock with one another.
The header and sill plastic cover pieces 65 and 67 interlock in a similar manner to the cover pieces 21 and 41 as do the, already described, cover pieces 51 and 57.
However, the sill cover piece 67, which includes arrow shaped heads 69 and 71 for snap locking with the barbed mouths 43 and 33 of the pieces 41 and 21, additionally includes a pair of bottom channel members 73. As will be seen in Figure 6, each of these channel members is provided with a T-shaped slot to slidingly engage correspondingly shaped T-shaped projections 77 on the top surface of a door sweep 75. This door sweep includes a pair of flex sweep members 79 which, as the door is opened and closed, deflect against a sill cap 87 of the actual door frame sill 85.
The sill cap is held in place by a screw as shown and the screw is covered by a small screw cover 82. A further O-shaped seal 81 is provided behind the most forward flex sweep 79 and a flexible wind and rain guard 83 is provided at the front of the door sweep.
Figure 7 shows the two flex sweeps 79 are slideably engaged to the main body 75 of the sweep member so that they can be replaced should they deteriorate over time.
Another feature of the present invention is well demonstrated in Figure 8 of the drawings. This feature relates to the construction of the door frame 3 for receiving the door panel frame 5. More particularly, the door frame 3 again has a plastic exterior cover 91 completely around the door frame. This cover includes a plastic door stop 93. Provided within the plastic door cover 91 are three separate metal reinforcing members 95, 99 and 105.
- 2~ 991 98 The two metal reinforcement members 95 and 99 are welded side by side reinforcing one another within the door frame in the areas where the door frame applies the most pressure. One of these areas is the door stop which, without the internal stiffeners, would tend to give way under pressure. To prevent this, reinforcing member 95 has a leg portion 97 which joins with leg portion 101 of reinforcing member 99 directly behind door stop 93.
Reinforcing member 95 further includes a leg portion 103 which is directed into the door stop 93. Reinforcing member 105 includes a leg 107 which cooperates with the combined strength of legs 97 and 101 of the other two reinforcing members again directly behind the door stop.
The strengthening of both the door frame and the door panel frame, as described above, produces a door assembly with an exterior surface having the desirable qualities of a plastic material such as vinyl with internal reinforcements strengthening the assembly and hidden by the plastic material.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
