Definitions
- wooden frames can be equipped [encased in part] with weather resistant surfaces by running the wooden components through a special extruder which places a weather resistant rigid polyvinylchloride shell on selected surfaces of the wood.
- An example of the latter is Andersen 400 series patio door which has an outer polyvinylchoride skin which is bonded to the exterior faces of the wooden components in an extruder of a special design which allows a wooden component to pass through the extruder when the skin or shell is applied to selected surfaces of the wooden component.
- novel patio doorframe of this invention is made of frame members, which are fully extruded members, employing multiple extruders.
- each frame member has a constant cross section, like pipe, rod, tube, etc. but with several integral components, including a rigid plastic shell for the exterior or weather faces of the frame member, a core element of polylvinylchloride/wood floor foam with channels formed therein for door components and integral flexible plastic sealing strips incorporated in the channels.
- Three or more extruders are employed in fabricating the novel frame member and coordinated to achieve a single extruded product.
- An extruded frame member for windows and doors having surfaces exposed to weather elements includes an integrated three element extrusion of a constant cross section having a core element with at least one channel formed therein, soft sealing strips integrated within said channel and a protective plastic shell formed on selected exterior surfaces of said core element extruded as an integral unit.
- On the surfaces of the core element not protected by the plastic shell wood patterns can be embossed for aesthetic reasons and core element is formed of materials which can be painted or stained so that frame member can be co-ordinated with the decor or of a room where the frame is installed.
- the manufacturing method of this invention also includes the steps of extruding a foamed selected profile of polylvinylchloride and wood flour with at least one channel therein and reduced dimension where a protective shell is desired, co-extruding a plastic shell of polylvinylchloride on the profile where the reduced dimension are provided in profile to form a protective shell, passing the co-extrusion through a calibration die, heating the co-extrusion form the calibration die at selected locations where weather stripping is desired, passing said co extrusion through a final extrusion die where weather stripping elements are extruded at the heated location and cooling the extrusion form the final extrusion die where weather stripping elements are extruded at the heated location and cooling the extrusion form the final extrusion die.
- Frame members constructed according to this invention have a plastic shell on their exterior or weather surfaces of any color selected before the members are extruded, such as white, sandstone, dark brown or any other color obtainable with pigments compatible with polyvinylchloride.
- the core element can include wood graining on its exposed surfaces and has channels for the door components formed therein without milling the core component. Also these channels include integrated plastic sealing strips for a door, when extruded.
- the core element is formed a wood flour laced polyvinylchloride foam extrusion, such as described the composition described in U.S. Letters Patent 6,380,272 issued to Chen.
- the plastic shell is weather resistant polyvinylchloride and the plastic sealing strips are a soft polyvinylchloride.
- the core element being an extruded part, can take advantage of hollow core-designs which lessen its weight without sacrificing strength and can include wood graining on the exposed surfaces which are not cover with the shell.
- the exposed surfaces of the core element can be painted or stained to coordinate with the interior of a room where a patio doorframe is installed. Colors such as country white, Spanish oak, dark mahogany, or any other suitable color can be used to provide an initial color to the core element.
- the core element is formed of a powered PVC, wood flour, thermal stabilizers, inorganic foaming aids, organic foaming agents, inorganic foaming agents, processing aids, modifiers, lubricants, fillers and pigments.
- a powered PVC wood flour
- thermal stabilizers inorganic foaming aids
- organic foaming agents organic foaming agents
- inorganic foaming agents processing aids
- modifiers modifiers
- lubricants fillers and pigments.
- Suitable polyvinylchloride [PVC] powers are those sold by Formosa Plastics Corporation as S-60 and S-65.
- the wood flour it can be derived form hardwood wastes, will preferably have a fiber length below 0.6 mm and a fiber diameter is between 0.04 to 0.6 mm along with an aspect ratio between 2 to 6.
- Such wood flour is sold by JRS as CB-120 as well as other entities.
- Thermal stabilizers are selected form organic and/or inorganic thermal stabilizer in powder form which are used to prevent the thermal degradation of PVC resin, typically organic tin carboxylate, organic tin mercaptide and barium/zinc stabilizer are preferred.
- Inorganic foaming aids are selected form magnesium oxide and zinc oxide, which are employed to increase the volume of gas form the organic and inorganic foaming agents.
- organic foaming agents selections can be made form azodicarbonamide, benzene-sulfohydrazide and diphenylene oxide-4, 4'-disulfohydrazide which act as blowing agents to provide gas for the foamed product.
- the inorganic foaming agent which also acts as product, can be blowing agents to provide gas for the foamed product, can be sodium bicarbonate.
- methyl methacrylate copolymer and high molecular weight acrylic polymers can be used as processing aids.
- Modifiers are employed for the purpose of increasing the strength of the plastic component in the composite and typically are selected form ethylene-vinyl acetate, acrylate/methyl methacrylate graft polymer and chlorinated polyethylene. Likewise it is also helpful to use external lubricants such as polyethylene wax and paraffin wax, which are employed to reduce friction during the extrusion process. Fatty acids, fatty alcohols and fatty acid esters are employed for the purposes of increasing the gelatinization of the powders during the extrusion step.
- fillers can be selected form calcium carbonate or precipitated calcium carbonate can be used and pigments such as titanium dioxide, iron oxide and carbon black can be employed.
- Extrusion machines having a twin-screw extruder such as the extruder model CM-65 built by Cincinnate further process the core mixture by shearing and heating it until it is gradually gelatinized as its is forced by the extruder into the adapter, then into the extrusion die and finally through the calibration die that controls the cross-sectional profile of the foamed core element of the novel frame member.
- each extruder is connected to the extruder for the core element ahead of the calibration die.
- One extruder contains weather resistant polyvinylchloride and extruders the shell, which forms the outer or exterior surfaces of the novel frame members. This shell extrusion marries with extruded core element in the machine.
- Suitable polyvinylchloride for the shell are those conventionally used for coated window and doorframes now on the market.
- the third extruder is likewise connected to the extruder for the core element and provides the soft plastic weather stripping elements in the channels formed in the core element during extrusion.
- the strips are applied the channels in the core element have been formed and strips are located in the channels where desired as the core element the shell as desired. This is accomplished after the shell-coated profile leaves the calibration die.
- the profile and is still hot and additional heat is applied to the profile where the strips are to be place for weather stripping, either is the core element or the shell.
- the profile passes through a final die where the soft polyvinylchloride is extruded in the desired locations.
- a soft polyvinylchloride such as EPDM purchased form Kupoaoch Chemical Limited can be employed.
- the extrusion passes through the calibration die controlling it final dimensions. As indicated above this profile is heated where the soft polyvinylchloride weather stripping is to locate and passes through the final die. After the three-element co-extrusion leaves the final calibration die passing the extrusion through a cooling tank cools it. Before cooling occurs a wood grain surface can be applied to the desired surfaces of the core element in the three-element co-extrusion by rollers having a reserves grain pattern on theirs surfaces.
- the continuous extrusion can be cut into appropriate lengths for forming a frame for a sliding or swing a patio doorframe, such as illustrated in Fig.4.
- Figures 1 and 2 illustrate several profiles employed in frame members for constructing a frame for a sliding glass patio door.
- the cross section in Fig. 1 is that of vertical frame member 20 for the fixed portion of the sliding glass door.
- the polyvinylchloride protective shell 21 is deployed on the surfaces of the frame member that will be exposed to the weather when a doorframe with this frame member 20 is installed in a building or home.
- the polyvinylchloride/wood flour core element 22, which is co-extruded with the protective shell 21, has a channel 23 for the frame of the fixed door of a sliding glass door.
- a third co-extrusion is carried out which places a soft polyvinylchloride sealing strip 24 in the channel 23 so that when the fixed door of the sliding glass door is installed these strips 24 will form a weather seal against a face of this fixed door.
- the polyvinylchloride/wood flour extrusion forming the core element 22 readily accepts paint and stains.
- the exposed surfaces 25, 26 and 27 of the core element 22 can be painted to coordinate with the color scheme of the interior room, which the sliding door services.
- frames using polyvinylchloride on all the surfaces of the frame were limited to color used by the manufacturer. Since materials used for the core element 22 are structurally sound, the frame member can have void coring 28, 29 and 30 to lighten the member and affect a cost savings in materials.
- a cross section of the vertical frame member 40 is illustrated, which is used on the opposite side of the door relative to frame member 20. It is constructed with a protective shell 41 on exterior surfaces of its core element 42 of polyvinylchloride/wood flour.
- the core element has a door channel 43 formed therein during the co-extrusion process described and a soft plastic sealing strip 44 in integrated in this channel 43.
- This sealing strip 44 is of softer vinyl than that used for the protective shell and is co-extruded with the protective shell 41.
- the surfaces of the core element 42 making up the three component co-extrusion readily accepts paints and/or stains allowing its interior surfaces 45, 46 and 47 to be painted or stained to coordinate with the room decor which the sliding glass door services.
- the core element 42 Since the core element 42 has adequate strength for making a doorframe, it has coring voids 48, 49 and 50 to reduce the weight and make the frame member more economical to produce.
- a further advantage is achieved with the fully extruded three component doortrame members, and that is providing weather stripping gloves 51 which are formed during the extrusion processes eliminating the necessity of milling the several frame members, with the accompanying cost savings.
- the composition of the core element in the several frame members is such that it can be worked with standard wood working tools, such as saws and drills and also be nailed to the supporting building structures when a frame constructed of this member is installed in a building.
- the bottom profile of the frame can be seen in the cross section illustrated in Fig. 3, and it can be this bottom frame member 60 is composed mostly of the same weather resistant polyvinylchloride 61 that is used for the shell on the other frame members. It has a small core element 62, which is extruded with the polyvinylchloride that allows the inside surfaces of the bottom frame member 60 to be stained or painted as previously described.
- the top 63 of this frame member 60 includes a doorpost 64 with a knob 65 at its top, which accepts a metal cap (not known) on which the rollers for the sliding glass door ride.
- the bottom of the glass door is grooved so that the doorpost 64 will be received in the groove.
- doorpost 64 can include sealing strips 66 and 67 which are formed of a soft polyvinylchloride and extruded simultaneously with the parts of the frame member. When used these sealing strips 66 and 67 prevent air drafts form passing under the sliding glass door. Also on the top of the bottom frame member grooves 68 and 69 are formed for receiving finishing strips (not known) that merely snap into these grooves. At the end of this frame member a toe piece 70, shown in phantom, can be secured in the grooves 71 and 72 provided for this purpose. Typically the toe piece 70 is an aluminum extrusion.
- Fig. 4 shows the cross section of the top frame member 80.
- the top frame member 80 Like the vertical frames members, it includes a core element 81 formed of polyvinylchloride and wood flour, a weather resistant plastic shell 82 on the portions of the core element 81 that will be exposed to weather conditions along with an integrated weather seal strip 83 which is formed of a soft plyvinylchloride.
- the individually identified components are extruded together in a single extrusion.
- the top frame member 80 there are two door channels 84 and 85 formed during the extrusion process with door channel having the protective plastic shell channel.
- the channel grooves 86 and 87 are provided for weather stripping (not known) for sides of a sliding glass door that moves back and forth through this channel. These weather stripping grooves 86 and 87 allow the weather stripping in channel 85 to be replaced if needed.
- coring voids 88, 89 and 90 are employed to reduce the cost of the materials without a loss of strength.
- the frame 100 is composed of vertical frame member 20 and vertical frame member 40 along with the bottom frame member 60 and the top frame member 80 shown in a building wall 101 illustrated in phantom.
- the frame members can be employed in both right hand opening doors and left hand opening doors by merely reversing the vertical frame members, top to bottom.
- the surfaces 91, 92 and 93 which are exposed inside the room when the frame is installed can be painted or stained to accommodate the room decor.
