Abstract

A modular step composed of a fiber reinforced thermoplastic. The modular step has a body and two flanges and is configured in size and shape to be detachably affixed to a window well. The modular step mates to the window using a friction fit, mechanical fasteners or tabs/slots. Multiple modular steps can be attached to a single window well. The modular step can be used to facilitate egress through a window well and improves the visual aesthetics of a window well.

Description

BACKGROUND

Technical Field

This disclosure generally relates to window wells, modular window well inserts, modular steps for window wells, and window well manufacturing processes that use fabric veils. More specifically, the present disclosure relates to modular steps that allows a user to safely and easily exit through a window well.

Related Technology

A window well is one type of a building component that can be used to hold back dirt and other material from a window that is below ground level. A typical window well is embodied as a U-shaped wall formed out of metal. One purpose of a window well is to let natural light into basement windows, while also providing an access point for entry/escape, should it be necessary. Window wells are often attached directly to a building structure and are visible from both the inside and outside of the building structure. Additionally, window wells must be strong enough to hold back and retain backfill soils without deflecting.

Many window wells are made of steel or a similar metal, which makes them relatively heavy and difficult/expensive to transport. Additionally, metal window wells can be easily damaged during transportation and installation. Even after installation, a metal window well can be damaged. For instance, a window well can be impacted by other devices after the window well has been installed. When a damaged window well needs to be replaced, it can be an expensive and time intensive process to excavate and replace an installed window well.

Additionally, since the window wells are exposed to the elements, they can become corroded and rust (depending on their material composition). Even when not corroded, metal window wells can be somewhat unattractive. Furthermore, it is difficult to make a metal window well look like a natural material or be aesthetically pleasing.

Some window wells are manufactured out of plastic materials, which makes them easier to apply an aesthetic texture to. However, the improved aesthetics often come at a cost of sacrificing durability and strength. In particular, existing window wells manufactured out of current plastic materials are typically not strong enough to compete with metal window wells because the types of plastic that are suitable for injection molding or rotomolding (the typical processes used for manufacturing plastic window wells), for example, cannot be used to manufacture a layered or reinforced plastic material.

Accordingly, there is a need for a window well that is durable, lightweight and visually attractive. Additionally, there is a need for improving techniques for repairing and replacing window wells.

The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced.

Overview of a Modular Step for a Window Well

Embodiments disclosed herein relate to a modular step that is configured in size and shape to be detachably affixed to a window well. The modular step allows a user to efficiently customize a window well by detachably attaching one or more modular steps to the window well. Additionally, the modular step provides better footing for a user that is exiting a building through the window well cavity. Thus, the modular step can be used to create an easily accessible exit that may be used during an emergency.

In some embodiments, the modular step is made of fiber reinforced thermoplastic and comprise of a body and one or more flanges. In some embodiments, the modular step may also be made of thermoset plastic or metal. In some embodiments, the flanges mate with the grooves of the window well. For example, some flanges snap into the window well grooves when a user firmly presses the modular step into the window well. In other words, the flanges and grooves create an interference fit that semi-permanently attaches the modular step to the window well. Similarly, in some embodiments the flanges have tabs that snap into corresponding slots in the window well. Thus, a user can install the modular step with minimal effort and costs and without having to remove the window well from a building structure.

A user can also remove the modular step from the window well with minimal effort. For example, in some embodiments a user can remove the modular step by horizontally pulling the modular step away from the window well. Thus, a user can easily modify the placement of the modular steps after attaching them to the window well.

The disclosed embodiments also include a modular handle that can be detachably attached to a window well. In other words, the modular handle is configured in size and shape to be detachably affixed to a window well. Thus, a user can further customize a window well by detachably attaching one or more modular handles.

Overall, the modular step provides a variety of improvements over traditional egress window wells.

The Lightweight and Durable Window Well

FIG. 1 illustrates a perspective view of one embodiment of a lightweight and durable window well 100. In FIG. 1, the body 105 of the window well 100 is a generally U-shaped wall. However, some embodiments have a body that is generally box or V shape. Furthermore, it should be noted that the body can be a wall of any shape that retains backfill soil (e.g., square, rectangular or circular/curve shaped).

In the embodiment shown in FIG. 1, the body 105 of the window well has ten grooves 110 and eleven wall surface portions 115. However, other embodiments include more or less grooves and wall surface portions. Further details on these grooves 110 and surface portions 115 will be provided later.

The lightweight and durable window well 100 also has substantially planar flanges 120 on each side. The flanges 120 are the portions of the window well which contact the structure and are disposed on distal or terminal ends of the window well 100. The planar flanges 120 have attachment holes 125 which facilitate installation of the lightweight and durable window well 100 (i.e., facilitate attaching the window well 100 to a structure).

The attachment holes 125 allow the lightweight and durable window well 100 to be fastened to a structure using a screw or a bolt. The attachment holes can be placed every 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 30 cm or more than 30 cm according to needs or preferences. Additionally, the size and shape of the holes can vary to allow for a variety of fasteners. It should be noted that some embodiments do not include attachment holes. In embodiments without attachment holes, a user can add custom holes during the installation (e.g., by using a drill).

The attachment holes 125 also help in the transportation of the lightweight and durable window well 100. For example, the attachment holes 125 can be used to align, stack or secure the window wells while the window wells are being transported. Additionally, more material/thickness can be positioned at the flanges 120 to increase the strength of the flanges 120, while also reducing the amount of material in the rest of the window well, thereby reducing the overall weight of the window well.

FIG. 2 illustrates a perspective view from the back of the lightweight and durable window well 100. In FIG. 2, ten ribs 130 are shown. It should be noted that the ribs 130 increase the stiffness and strength of the window well. Additionally, each one of these ribs 130 has a corresponding groove 110. In other words, the ribs 130 and grooves 110 are opposite sides of the same features (i.e., the groove describes the front/inside surface while the rib describes the back/outside surface of the same feature). Additionally, more details on these ribs 130 will be provided later.

The lightweight and durable window well 100 is also configured, in some embodiments, with one or more four directional indicators 200. The directional indicators 200 facilitate proper placement during installation by helping a user correctly orient the window well 100. The indicators 200 also facilitate proper orientation during storage and shipping. For example, in some embodiments, the window wells can be stored more compactly if all the window wells in storage have the same orientation.

The directional indicators 200 can be formed into the surface of the window well 100 (i.e., the indicators 200 can be molded directly into the window well 100). However, in some embodiments, the directional indicators are formed into the window well 100 after the molding process (e.g., through etching or stamping). In yet other embodiments, the directional indicators can be printed on the window well.

In FIG. 2, the directional indicators 200 comprise of a directional arrow and the word “UP.” In some embodiments, the directional indicators only consist of either an arrow or a word (e.g., the word “TOP” on the top portion of the window well). In some embodiments, the window well only has one directional indicator. However, in other embodiments the window well has two or more indicators. Additionally, the directional indicators can be placed on the front and/or back of the window well.

FIG. 3 illustrates a front view of the lightweight and durable window well 100. The lightweight and durable window well 100 has two tabs 305 and two slots 205 on the bottom groove 110 and rib 130, respectively. However, in some embodiments, the window well has tabs on multiple grooves and slots on multiple ribs. Additionally, some embodiments have tabs on every groove and slots on every rib. It should also be noted that some embodiments have more than two slots and tabs per groove/rib. Additionally, some embodiments, have no tabs and/or slots (e.g., window well 400). More details on these tabs and slots will be provided later.

FIGS. 4 through 8 illustrate multiple views of a lightweight and durable window well 400. The height of the body 105 of the window well 100 may vary to accommodate different needs and preferences, from 30 cm to 35 cm, 40 cm, 50 cm, 100 cm, 150 cm, 200 cm or more than 200 cm. Likewise, the width (i.e., the distance between the two opposite planar flanges) and the depth (i.e., the distance from the front of the planar flanges to the furthest point on the back of the ribbing) of the body 105 of the window well 100 may vary to accommodate different needs and preferences, from 0.25 m to 1 m, 2 m, 3 m or more than 3 m.

Additionally, the lightweight and durable window well 100 can be formed of different materials, such as a thermoplastic composite. It should be noted that the embodiment in FIGS. 1 through 8 is made of long fiberglass reinforced polypropylene.

However, some window wells within the scope of the present invention are made of a different thermoplastic composite. For example, some embodiments use long fiber reinforced thermoplastic (LFRT) (e.g., fiberglass reinforced polypropylene, reinforced nylon, rigid thermoplastic polyurethane, polybutylene terephthalate, polyetherimide, polyphthalamide, or some other reinforced thermoplastic). Additionally, some embodiments are manufactured from a glass mat thermoplastic or a continuous fiber reinforced thermoplastic. Furthermore, it should be noted that other fiber reinforced plastics may be used if the material is suitable for high pressure thermoforming such as, but not limited to, sheet molding compounds, bulk molding compounds and other high-performance thermoset composites.

In some embodiments, the thermoplastic is reinforced using fibers, such as glass fibers, carbon fibers or natural fibers (e.g., hemp, flax, ramie). These fibers may have variable lengths, but preferably include at least some relatively long fibers having lengths of greater than the length that is generally suitable/desired for injection molding plastics (e.g., 6 mm to 10 mm). In some instances, the fiber lengths of at least some fibers in the window well are greater than 12.5 mm and, in some instances, greater than 25 mm. In some embodiments, the average length of the fibers ranges from 25 mm to 45 mm. In other embodiments, the average length of the fibers ranges from 45 mm to 80 mm. In yet other embodiments, the average length of the fibers ranges from 80 mm to 120 mm. Additionally, some embodiments have continuous fibers having lengths of many millimeters (e.g., greater than 150 mm).

In some embodiments, the fibers are oriented in random directions (e.g., random directional or omnidirectional relative to other fibers in the material). In other embodiments, the fibers are positioned substantially unidirectionally. Notably, the directionality of the fibers is specifically descriptive with reference to the orientation of a fiber with relationship to other fibers within the material as contained within the relatively flat portions of the molded material (e.g., not the curved or angular portions of the molded material where even unidirectionally positioned fibers will have alignments that are not parallel with other fibers in the flat portions (i.e., the wall surface portions) of the molded material).

In many instances, the reinforced thermoplastic is lighter and more durable to environmental conditions than traditional window well materials, such as metal and other plastics. For example, the reinforced thermoplastic material is more UV resistant and rust/corrosion resistant than traditional materials used to manufacture window wells. The reinforced thermoplastic material also performs well at low temperatures and has increased heat resistance.

Furthermore, the reinforced thermoplastic is more impact resistant than traditional window well materials. In other words, the disclosed embodiments can experience more torsion, bending and impact forces without deforming or cracking, as compared to traditional window wells. Overall, because of the high-quality and strength of the reinforced thermoplastic material, the lightweight and durable window well 100 has a longer lifespan than traditional window wells.

The design of disclosed embodiments also adds strength and durability to the lightweight and durable window well 100. For example, the ribs 130 significantly increase the stiffness of the lightweight and durable window well 100. In some embodiments, the ribs are only visible on the backside of the window well. In other words, the front surface of the window well is substantially flat and does not contain or visually show the ribs that are present on the back surface of the window well.

FIG. 9A is a cross-section side view of the window well 100 which illustrates a cross-section of these ribs 130. FIG. 9A also illustrates a cross-section of the grooves 110. As discussed above, the grooves 110 define the general shape of the ribs 130 of the window well 100. It should also be noted that the grooves 110 and ribs 130 improve the visual aesthetics of the window well 100. While the current embodiment shows ten ribs 130, it will be appreciated that the window well 100 can include more or fewer than ten ribs.

The spacing between the grooves/ribs 110, 130 can also vary to accommodate different needs and preferences (e.g., 5-10 cm), or less (e.g., 4-6 cm or less) or more (e.g., 10-12 cm or more). In some embodiments, the distance between the grooves/ribs is different within the same window well. For example, one distance between the grooves/ribs is 5 cm, while the next distance between the grooves/ribs is 15 cm.

Additionally, as discussed above, the body of the window well 100 includes a plurality of wall surface portions which surround each groove 110. However, in some embodiments, there is only one wall surface portion (i.e., there are no grooves). The wall surface portion may vary in height to accommodate different needs and preferences, from 10 cm, 20 cm, 30 cm, 40 cm, 50 cm, 60 cm or more than 60 cm. Additionally, in some embodiments, the wall surface portions follow the curvature of the body of the window well. However, the depth of the wall surface portion may vary to accommodate different needs and preferences, from 10 cm, 25 cm, 50 cm, 75 cm, 100 cm or more than 100 cm.

FIG. 9B includes a close-up view of the grooves 110 and the ribs 130. It should be noted that the height of the groove 110 is defined by a greatest open latitudinal space within the groove 110 at any corresponding point in the groove 110 (i.e., the distance between the top of the groove and the bottom of the groove at the front surface of the window well). Similarly, the depth of the groove 110 is defined by a greatest longitudinal distance in the groove 110, as measured from a flat surface of the window well to the most interior portion of the groove 110.

In some embodiments, the wall thickness varies. For example, FIG. 9B illustrates both a wall 905 with a constant thickness and, in dashed lines, a wall 910 with varying thickness. In some instances, the wall thickness varies from 3-4 mm (furthest from the ribs) to 6-7 mm (nearest the ribs). It should be noted that positioning more material/thickness at the ribs increases the strength of the window well, while also reducing the amount of material between the ribs to thereby reduce the overall weight of the window well.

Although FIG. 9B illustrates the wall 910 expanding outwards, in some embodiments the wall expands inwards. In other words, in some embodiments, the height and depth of the grooves decrease as the wall expands. Additionally, in some embodiment, the wall thickness changes more dramatically. For example, the wall thickness can vary from 1-3 mm (furthest from the ribs) to 7-8 mm (nearest the ribs).

Additionally, in some embodiments the top lip of the window well is reinforced. For example, FIGS. 10A and 10B illustrate one embodiment of a window well with a reinforced (i.e., thicker) top lip 1005. The reinforced top lip 1005 protects the window well from impact damage during transportation and installation. Additionally, the reinforced top lip 1005 increases the overall durability of the window well. In some embodiments, the reinforced top lip 1005 is 20% to 100% thicker than the non-reinforced portions (i.e., the regular wall thickness). Additionally, in some embodiments, the reinforced top lip 1005 is 40% to 60% thicker than the non-reinforced portions and even more preferably 50% thicker. However, in some instances the reinforced lip 1005 is less than 20% thicker or more than 100% thicker than the non-reinforced portions.

In some embodiments, the region around the attachment holes can also be reinforced. For example, FIGS. 10C, 10D and 10E illustrate one embodiment of a window well with reinforced (i.e., thicker) regions 1010 that surround the attachment holes 125. The reinforced regions 1010 (i.e., the wall immediately surrounding the attachment holes 125) are 20% to 100% thicker than non-reinforced regions. Additionally, in some embodiments, the reinforced regions 1010 are 40% to 60% thicker than the non-reinforced regions and even more preferably 50% thicker. However, in some instances the reinforced regions 1010 are less than 20% thicker or more than 100% thicker than the non-reinforced portions.

In some instances, the grooves 110 vary in height and depth throughout their length and may have different dimensions as described below. In the illustrated embodiment, the grooves 110 expand from the center (i.e., the position between the two outer edges of the window well) of the groove 110 (see FIG. 12) to the terminating ends of the groove 110 (see FIG. 11, which is a cross-section near but not at a terminating end).

This configuration can increase the strength of the ribs 130 and improve the molding of the window wells. The variability in height of the grooves 110 may be greater than 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm or more than 6 mm, from a smallest height dimension to a greatest height dimension, of the variable height along a single groove 110 length. In some embodiments, the variability in depth may be greater than 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm or more than 6 mm, from a smallest depth dimension to a greatest depth dimension, of the variable depth along a single groove 110 length.

However, in some embodiments the grooves 110 maintain a constant height and depth throughout their length. In other words, the cross-section would remain the same throughout the window well's entire length.

Additionally, the varying height, depth and shape of the grooves 110 and ribs 130 improves the stacking ability of the window wells. The wall angles of the window wells also improve the stacking ability of the window wells. Therefore, the amount of window wells that can be transported on a single pallet is increased. In some embodiments, the ribs 130 of the lightweight and durable window well are manufactured with draft angles which prevent the window wells from binding together when stacked. Therefore, the draft angles of the ribs 130 facilitate the unpacking of window wells from a pallet. The increase efficiency in the packing, transporting and unpacking of the window wells can significantly reduce manufacturing and shipping costs.

In some alternative embodiments, the grooves maintain a constant height and/or depth. For instance, the fixed depth may be a depth of 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or more than 7 mm. Likewise, the fixed height may be a height of 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or more than 7 mm.

Additionally, in some embodiments, the grooves have a flared portion 210, see FIGS. 2 and 3, at the terminal ends of the grooves. More particularly, the height and the depth of the groove substantially increases at the terminal ends of the grooves (i.e., each groove expand more dramatically the last 5-10 cm of each side of the groove). In embodiments with flared portions, the variability in height of the grooves within the flared portions may be greater than 1 mm, 2 mm, 4 mm, 6 mm, 8 mm or more than 8 mm. Similarly, in embodiments with flared portions, the variability in depth of the grooves within the flared portions may be greater than 1 mm, 2 mm, 4 mm, 6 mm, 8 mm or more than 8 mm. However, in some embodiments, there are no flared portions at the end of the grooves.

In some embodiments, the flared portions have a fastening mechanism to facilitate stacking and transportation. For example, in FIGS. 2 and 3, the flared portions 210 have tabs 305 within the inner rib surface (e.g., along the groove) and slots 205 along the outer rib surface that snap into a friction fit with opposing slots/tabs positioned on the opposing rib surface of an adjacent window well. However, in some embodiments, the tabs are positioned along the outer rib surface, and the slots are positioned within the inner rib surface.

Additionally, some embodiments without flared portions also have a fastening mechanism (e.g., a protruding tab—not shown) along the grooves and/or ribs. In other embodiments, stacked window wells may be held together using a friction fit between the grooves and the ribs. Some embodiments use both a fastening mechanism and a friction fit to facilitate the stacking and transporting of window wells. Overall, the flared portions of the grooves can improve the aesthetics of the lightweight and durable window well, as well as improve the stacking ability of the window wells.

The aesthetics of the window well may also be improved by applying a texture or pattern to the surface of the window well. FIGS. 13 and 14 show examples of textures or patterns that can be added to the window well. More particularly, FIG. 13 illustrates an acid-etched texture with a horizontal grain, and FIG. 14 illustrates a laser-etched texture with a wave pattern.

The texture can be etched onto the surface of the mold and, thereby, into the window well when the window well is molded. The texture patterns can vary to accommodate different preference and structures (e.g., horizontal grain patterns, vertical grain patterns, wave patterns, symmetrical patterns and asymmetrical patterns).

In some embodiments, a fabric veil is used to increase the realism of a texture or pattern. For example, the realism and natural look of a stone texture can be improved by applying a multi-colored veil onto the window well. To apply the veil to the window well, the fabric veil is inserted into the compression mold before the window well is manufactured. In other words, the fabric veil is positioned within the mold on top of the heated fiber reinforced thermoplastic sheet. However, in some embodiments, the fabric veil is positioned within the mold below the heated fiber reinforced thermoplastic sheet. Then during the molding/compression, the multi-colored pattern is embedded into the texture of the window well. The fabric veil can also be used to achieve other natural/organic looks such as wood, marble and granite textures.

This process of using a fabric veil can be particularly beneficial for blocking unsightly fibers and to provide more control over the final aesthetics that are presented as the exterior of the window well. Additionally, the texture minimizes minor blemishes that are caused by the molding/compression process. Overall, using a fabric veil can significantly add to the overall realism of the organic surface texturing caused by the mold (and/or subsequent acid etching or other finishing processes), which is typically difficult to achieve for thermoplastic materials, particularly those that are impregnated with fibers. The veil/fabric can also add additional strength and integrity to the final product. For example, the veil can increase the stiffness and durability of the window well. More details on the fabric veil will be provided later.

Manufacturing Process for the Lightweight and Durable Window Well

The lightweight and durable window well is manufactured using a two-part mold, and one or more sheets of plastic. In some embodiments, the window well is manufactured using one or more sheets of fiber reinforced thermoplastic. FIG. 15 illustrates the male mold 1500 and FIG. 16 illustrates the female mold 1600. Both illustrated molds are made of aluminum. However, some embodiments may use molds of a different material (e.g., steel, composite, etc.). Additionally, in some embodiments, the molds have guide pins (not shown) to ensure that the two molds align during compression.

In some embodiments, the molds are designed so that the window well has varying wall thickness. For example, in some embodiments the wall will be thicker in the ribbed areas and thinner in the non-ribbed areas. In other words, in some embodiments, the wall is thickest at the ribs and/or the portions of the wall near the ribs. In some instances, the wall surface portions near the ribs are thicker than parts of the wall surface portions that are furthest from the ribs, such as the wall surface portions that are centrally positioned between the ribs.

It should be noted that in order to create the ribs on the window well, the mold also needs to have ribbing. Furthermore, some embodiments require additional material (e.g., additional strips of reinforced thermoplastic) to be placed at the ribs of the mold. The varying wall thickness allows the window wells to be strong while also being lightweight. The varying wall thickness also allows the molding process to be more efficient, such as by allowing the fiber reinforced plastic (and particularly the long fibers) to flow through the mold more efficiently during the molding process.

In alternative embodiments, the mold is configured with ribs and spacing that cause the molded window well to have a uniform thickness throughout the body, grooves and/or ribs. Additionally, in some embodiments, the mold is configured to make a window well with a height of 2 m, 3 m or more than 3 m. The window well can then be cut to produce two or three window wells. For example, a window well with a height of 3 m can be cut into two window wells (e.g., a 2 m window well and a 1 m window well). However, it should be noted that the steps and methods for producing the window wells are the same or similar regardless of the size of the window well.

FIG. 17 illustrates a flow chart of an exemplary method for producing the lightweight and durable window well. In the first step 1705, fiber reinforced thermoplastic sheets are heated to a relatively high temperature (e.g., greater than 250° F. and, in some instances, to above 300° F.). In some embodiments, the sheets of fiber reinforced thermoplastic are heated to temperatures of about 385° F. or, in some embodiments, above 385° F. prior to or during the compression.

When the sheets of reinforced thermoplastic are heated, the sheets loft up or expand from about 3.8 mm to a thickness of about 5 mm (e.g., greater than 10%, greater than 15%, greater than 20% or more than a 20% increase in sheet thickness). Using lofted sheets increases the quality of the lightweight and durable window well by allowing the thermoplastic to have increased flow once it is placed on the mold.

In the next step 1710, the heated fiber reinforced thermoplastic sheet or sheets are placed in the mold. If a fabric veil is being used, then the fabric veil is placed into the mold on top of the heated fiber reinforced thermoplastic sheet or sheets.

In some embodiments of step 1710, the fabric veil is placed into the mold before the heated thermoplastic sheet or sheets. In such embodiments, after placing the veil into the mold, the heated thermoplastic sheet is then placed into the mold on top of the veil.

Then, for both embodiments (with the veil placed over or under the thermoplastic sheet(s)), the heated fiber reinforced sheet or sheets are compressed between the male mold 1500 and the female mold 1600 (step 1715).

In some embodiments, the window wells are molded and compressed with pressures ranging from 200 psi, or about 200 psi, to 900 psi, or about 900 psi, for a duration of between 30 seconds (or about 30 seconds) and up to 60 seconds (or about 60 seconds), and even more preferably within a range of between 300 psi and 800 psi for a duration of 30-60 seconds. Additionally, in some embodiments, the pressure is between 300 psi and 400 psi. In other embodiments the pressure is less than 200 psi or more than 800 psi. The duration may also be less than 30 seconds or more than 60 seconds. The compression causes the sheet or sheets of reinforced thermoplastic to take the shape of the mold.

During molding, the male mold 1500 and/or the female mold 1600 may be heated or cooled during the molding/compressing processes. In some embodiments, the molds are heated during some parts of the molding/compressing process and cooled during other parts of the process. However, in some embodiments, the molds are neither heated nor cooled.

In some embodiments, thermoset plastic (e.g., high impact polystyrene) is used for the lightweight and durable window well. In some thermoset manufacturing methods, the first step is to place a fabric veil into a male mold. However, in some embodiments, the fabric veil is placed into a female mold. Additionally, some embodiments do not use a veil.

After the veil has been placed into the mold, one or more fiberglass sheets are placed over the veil. In embodiments that do not use a veil, the one or more fiberglass sheets are placed directly onto the mold. It should be noted that neither the veil nor the fiberglass sheets need to be preheated. However, in some embodiments, the fiberglass sheets are preheated.

Once the veil and the one or more fiberglass sheets have been placed onto the mold, the veil and fiberglass sheets are vacuum sealed against the mold. Thus, the veil and fiberglass sheets are forced into the shape of the mold. In some embodiments, a vacuum bag is used to create the vacuum seal.

After the vacuum seal is created, a thermoset resin is drawn into the molding chamber. In some embodiments, the thermoset resin is pulled into the mold by the vacuum. Alternatively, the resin may be pushed into the mold using a pump. Additionally, some embodiments use both a vacuum and a pump. In some embodiments, the thermoset resin is heated before it enters the molding chamber.

Once the thermoset resin enters the molding chamber, the resin saturates the one or more fiberglass sheets and veil simultaneously and begins to cure. More specifically, the thermoset resin begins to harden and the polymer chains in the resin begin to cross-link with one another. During this process, the veil and fiberglass sheets are permanently bonded to the resin and to each other. Additionally, in some embodiments, the curing process is an exothermic reaction and does not require any external heating.

In some embodiments, the curing process takes less than 6 hours. However, in other embodiments, the curing process takes less than 24 hours. Additionally, the curing process can be accelerated by adding external heat. Thus, in some embodiments, the curing process is sped up using infrared lights or some other heating device.

As discussed above, it should be noted that the window well may be formed from a single sheet of material. In other embodiments, the window well is formed, during molding, from multiple different sheets of material that are positioned adjacent each other on the mold and that are molded/compressed into each other during the molding process.

In other embodiments, the window well is formed, during molding, from multiple different sheets of material that are stacked or overlapped such that a portion of one sheet overlaps at least a portion of another sheet on the mold and that are molded/compressed into each other during the molding process. In other words, some embodiments require the user to place multiple heated sheets of fiber reinforced thermoplastic within the mold. This may be beneficial, for example, when a single sheet is not large enough to cover an entire mold and/or for facilitating the apportionment of additional material to the rib sections, by positioning/layering strips of additional material where the ribs are formed, such that that ribs are composed of stacked layers (2 or more) of thermoplastic material.

In some embodiments, the window well is also deflashed/trimmed after compression to remove any excess material (see Step 1720). However, in some embodiments the part may be molded to near net shape on all sides. Additionally, in some embodiments, the window well coloring is controlled by color pigments added to the plastic/fibers used in the reinforced thermoplastic. However, in some embodiments, the window well is painted after molding.

Modular Insert

The exemplary method in FIG. 17 can also be used to produce a lightweight and durable modular insert. Thus, the modular insert can be produced from the same material that is used for the lightweight and durable window well, such as long fiber reinforced thermoplastic or long fiber reinforced thermoset plastic. For example, in some embodiments, the modular insert is manufactured from long fiber reinforced polypropylene.

Furthermore, in some embodiments, at least some of the fibers within the long fiber reinforced thermoplastic or thermoset plastic are omnidirectional and have a length greater than 5 mm. Similarly, some embodiments use thermoplastic reinforced with at least some fibers that have a length greater than 20 mm, 40 mm or 60 mm.

Although it is preferable to have fibers that are greater than 40 mm long for enhanced strength, it has been found that the benefits of the disclosed invention are also achieved using fibers lengths of less than 40 mm. The benefits of the disclosed inventions can even be achieved using fibers less than 5 mm in length. It should be noted that using shorter fibers increases the flow of materials during molding. In some instances, the modular window well has different fiber lengths in different body portions. For example, the central portions of the body can have shorter fibers for increased flowability while the outer portions/edges of the modular insert can have longer fibers for increased strength. Additionally, in some embodiments, a fabric veil is used to give the modular insert a more realistic or natural look.

In some embodiments, the modular insert is used alongside a window well. For example, a modular insert can be used to increase the height of a lightweight and durable window well. Additionally, a modular insert can be used to repair a damaged window well. Further details on the installation methods of the modular insert will be provided later.

FIGS. 18 and 19 illustrate perspective views of a modular insert 1800. The modular insert 1800 has the same general shape and design of the main window well, but with fewer grooves 1805, wall surface portions 1810 and ribs 1815. In the present embodiment, for example, the body 1820 of the modular insert 1800 includes two ribs 1815 and three wall surface portions 1810. In other words, the body 1820 of the modular insert 1800 has a plurality of ribs 1815 interposed between a plurality of wall surface portions 1810. Additionally, some embodiments of a modular insert may have more than two ribs, grooves and wall surface portions. Similarly, some embodiments of a modular insert may have fewer than two ribs, grooves and wall surface portions.

FIGS. 20 and 21 illustrate a top and bottom view, respectively, of the modular insert 1800 and illustrate the generally U-shaped body 1820 of the modular insert 1800. However, some embodiments of the modular insert have bodies that are a different shape in order to match the shape of the lightweight and durable window well. In other words, the body of the modular insert can be a wall of any shape that retains backfill soil (e.g., square, rectangular or circular/curve shaped).

FIGS. 22 and 23 illustrate a back and front view, respectively, of the modular insert 1800. Like the lightweight and durable window well, the modular insert 1800 has attachment holes 2205, directional indicators 2210 and flanges 2215. The attachment holes 2205 and the directional indicators 2210 facilitate proper placement during installation by helping a user correctly orient the modular insert 1800. However, some embodiments of the lightweight and durable modular insert do not have attachment holes or directional indicators.

During installation, the attachment holes 2205 of the modular insert 1800 align with the attachment holes of a lightweight and durable window well (e.g., 125 of FIG. 1). In other words, one or more of the modular insert's 1800 attachment holes 2205 align with one or more of the window well's attachment holes when the modular insert 1800 is mated to the window well. Therefore, a user can mate the modular insert to a window well by inserting a fastener (e.g., a bolt or screw) through the aligned attachment holes and into a structure.

However, in some embodiments, the attachment holes of the modular insert and the window well do not align. Thus, in some embodiments, a user will need to add additional attachment holes (e.g., with a drill) that allow fasteners to go through both the modular insert and the window well. Further details on the fastening methods of the modular insert will be provided later.

In some embodiments, the modular insert 1800 also has a recessed section 2220. One purpose of the recessed section 2220 is to facilitate the mating of the modular insert 1800 and the lightweight and durable window well. In other words, the recessed section 2220 allows the modular insert 1800 to be installed to a window well in a close sliding fit.

The recessed section 2220 has a greater depth than the rest of the modular insert 1800. It should be noted that the depth is measured from the front of the planar flanges to the furthest point on the back of the ribbing. In other words, the recessed section 2220 is not flush with the rest of the flange 2215 but instead is more towards the back of the ribbing.

In some embodiments, the recessed section 2220 is recessed by the amount necessary for the modular insert 1800 to slide in behind the window well. For example, if a window well has a wall thickness of 3 mm, then the recessed section 2220 would have an added depth of about 3 mm. Similarly, if a window well has a wall thickness that varies (see FIG. 10), then the added depth of the recessed section 2220 would match the window well's variations in wall thickness. Therefore, the added depth of the recessed section 2220 allows a user to place a modular insert 1800 flush behind a window well without having to modify either the modular insert 1800 or the window well.

In other words, the added depth of the recessed section 2220 may vary to accommodate different needs and preferences, from 1 mm to 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or more than 7 mm. Additionally, in some embodiments, the added depth of the recessed section 2220 varies from 2-5 mm (furthest from the ribs) to 5-8 mm (nearest the ribs).

FIGS. 24 and 25 illustrate a right and left view, respectively, of the modular insert 1800. They also illustrate another view of the recessed section 2220. The height of the recessed section may vary to accommodate different needs and preferences, from 2 cm, 5 cm, 7 cm, 10 cm, 12 cm, 15 cm, 25 cm or more than 25 cm. Similarly, the height of the modular insert may vary to accommodate different needs and preferences, from 25 cm, 50 cm, 75 cm, 100 cm, 125 cm, 150 cm or more than 150 cm.

In some embodiments, the height of the modular insert 1800 in relation to the height of a window well may vary to accommodate different needs and preferences, from ½ to ⅓, ¼, ⅕, 1/10 or less than 1/10 of the height of the window well that is being extended or repaired. Additionally, in some embodiments, the height of the modular insert 1800 in relation to the height of the window well may vary to accommodate different needs and preferences, from 75% to 60%, 50%, 30%, 25% or less than 25% of the height of the window well that is being extended or repaired.

Additionally, FIG. 26 illustrates a left-side cross section of an embodiment of the modular insert 2600. In some embodiments, the recessed section 2220 runs across the top of the modular insert 2600. Thus, the modular insert 2600 may be installed and attached to the bottom of a window well, as oppose to the top of the window well. However, in other embodiments the modular insert has a recessed section on the bottom of the modular insert that mates to the top section of a window well.

In some embodiments, the modular insert has more than one recessed section. For example, some embodiments of the modular insert have recessed sections on both the top of the modular insert and the bottom of the modular insert. Thus, a user can attach the modular insert to two different window wells.

The modular insert can also be used to repair the middle portion of a window well. In other words, a user can remove the middle section of a window well (e.g., by cutting off the damaged portion) and replace the damaged portion with a modular insert. It should be noted that some embodiments of the modular insert are design to be attached at any rib. For instance, a user can cut off the top half of the window well and attach the modular insert onto the new top-most rib or half rib.

Additionally, in some embodiments, the modular insert does not have a recessed section. Thus, instead of using a recessed section to mate with the window well, the modular insert uses an interference fit and/or a friction fit to mate with the window well.

FIG. 27 illustrates a close-up view of a cross section of the grooves 2710 and the ribs 2705 of the modular insert 2600. It should be noted that the shape and size of the grooves 2710 and ribs 2705 of the modular insert 2600 is the same as the shape and size of the grooves and ribs of the lightweight and durable window well (See FIGS. 11 and 12). Thus, in some embodiments, each rib 2705 is defined by a variable height and a variable depth.

Additionally, in some embodiments, the modular insert 2600 has a body with a varying wall thickness. For example, FIG. 27 illustrates both a wall with a constant thickness 2715 and, in dashed lines, a wall with varying thickness 2720. Additionally, in some embodiments the variable wall thickness of the body is thicker at the ribs than the wall surface portion. More particularly, the wall thickness may vary from 2-5 mm (furthest from the ribs) to 5-8 mm (nearest the ribs). Additionally, in some embodiments the variable wall surface portions have a variable thickness, varying from a minimal thickness of less than 3 mm to a maximum thickness of greater than 5 mm.

FIGS. 28 and 29 illustrate a perspective view of another embodiment of the modular insert 2800. In FIGS. 28 and 29, the modular insert 2800 has slots 2805 and tabs 2905. More specifically, the modular insert 2800 has six slots 2805 (two not shown) on the top side of the top rib. Similarly, the modular insert 2800 has six tabs 2905 (two not shown) on the top have of the bottom grooves. It should be noted that the number of tabs and slots may vary to accommodate different needs and preferences, from 1, 2, 3, 4, 5, 10, 15, 20 or more than 20 tabs and slots.

The tabs and slots may also be placed on any of the grooves and/or ribs. Additionally, multiple grooves can have tabs and/or multiple ribs can have slots. In some embodiments, all of the grooves have tabs and all of the ribs have slots. The position of tabs and slots can also be switched. In other words, the tabs can be place on the ribs and the slots can be placed in the grooves.

When the modular insert 2800 is attached to another modular insert 2800 the tabs 2905 insert the slots 2805. Thus, the modular inserts 2800 become interlocked with one another. In some embodiments, the slots 2805 and tabs 2905 create a friction fit (e.g., the tabs snap into place) when they interlock. Thus, a user does not need to use additional fasteners to install a modular insert 2800 to another modular insert 2800.

In some embodiments, a lightweight and durable window well has slots that correspond to the tabs on the modular insert 2800. Similarly, some embodiments of the lightweight and durable window well have tabs that correspond to the slots on the modular insert 2800. Thus, the modular insert 2800 can be attached to a lightweight and durable window well using tabs and/or slots. For example, in some embodiments, the tabs of the modular insert 2800 snap into the slots of the window well and create a friction fit when the modular insert 2800 is attached to the window well.

In some embodiments, the slots and tabs hold the modular insert 2800 in place while another fastening method is added. For example, in some embodiments, the slots and tabs align the modular insert with the window well while backfill soil is placed behind the modular insert. Then, a combination of the backfill soil and the friction fit of the tabs and slots fastens the modular insert to the window well.

In a similar embodiment, the tabs and slots are used to align the modular insert with the window well, but do not create a friction fit. Instead, the modular insert is fastened to the window well by placing bolts or screws into the modular insert's attachment holes. Regardless of the fastening method, the modular insert can be used to repair or extend the height of a window well.

For example, FIG. 30 illustrates a back-perspective view of a lightweight and durable window well 400 that has the modular insert 1800 attached. Similarly, FIG. 31 illustrates a front-perspective view of the same window well 400 and modular insert 1800. Furthermore, FIGS. 32, 33 and 34 illustrate close-up views of the small seam between the modular insert 1800 and the window well 400. In some embodiments, when a modular insert 1800 is mated to a window well 400, the insert 1800 and the window well 400 create an almost seamless extended window well. In other words, a user would not be able to easily identify where the window well 400 ends and where the modular insert 1800 begins.

In some embodiments, multiple modular inserts may be attached to the window well. For example, FIG. 35 illustrates an example of a window well 400 configured with one attached modular insert 3500 positioned in attachment with the window well 400. Additionally, FIG. 35 illustrates a modular insert 1800 that may be attached to the middle modular insert 3500. It should be noted that the middle modular insert 3500 has a taller recessed section 3505 than the top modular insert's 1800 recessed section 2220.

FIG. 36 illustrates an example of a window well 400 configured with two attached modular inserts, 1800 and 3500, positioned in attachment with the window well 400. More particularly, the bottom of the modular insert 1800 is attached to the top of the modular insert 3500. Similarly, the bottom of the modular insert 3500 is attached to the top of the window well 400. It should be noted that a modular insert may also be attached to the bottom of the window well 400. Overall, the modular inserts allow for a high level of customizability and allows a user to adjust the height of a window well to his or her needs or preferences.

Additionally, the height of the window well 400 is reflected by the bracket 3615. Similarly, the height of the modular insert 3500 is reflected by the bracket 3610, and the height of the modular insert 1800 is reflected by the bracket 3605. It should be noted that the window well 400 and the modular insert 3500 overlap by the amount indicated by bracket 3625. Similarly, the middle modular insert 3500 and the top modular insert 1800 overlap by the amount indicated by bracket 3620.

As mentioned above, in some embodiments, the attachment holes (e.g., 125 of FIG. 1) in the flanges (e.g., 120 of FIG. 1), line up with each of the modular inserts and/or the window well, when they are nested/placed together in the configuration shown, so as to further facilitate their installation in an aligned and correct fashion. However, in some embodiments, the attachment holes of the window well and the modular inserts do not line up.

The amount of overlap between a window well and a modular insert may vary to accommodate different needs and preferences, from 3 cm, 5 cm, 10 cm, 20 cm, 30 cm or more than 30 cm. Similarly, the amount of overlap between one modular insert and a different modular insert may vary to accommodate different needs and preferences, from 3 cm, 5 cm, 10 cm, 20 cm, 30 cm or more than 30 cm.

For example, in FIG. 36, the bottom portion of the bottom groove of the modular insert 1800 overlaps with the top ridge of the modular insert 3500. In other words, the modular inserts, 1800 and 3500, have about 4 cm of overlap (see bracket 3620). Similarly, the second to bottom groove of the modular insert 3500 overlaps with the top ridge of the window well 400. However, unlike the overlap of modular inserts 1800 and 3500, the bottom groove of the modular insert 3500 also overlaps with the top groove of the window well 400. In other words, the modular insert 3500 and the window well 400 have about 12 cm of overlap (see bracket 3625).

Additionally, in some embodiments, a modular insert and a window well have two or more grooves that overlap. Similarly, in some embodiments, a modular insert and a different modular insert have two or more grooves that overlap. It should be noted that in some embodiments, the amount of overlap corresponds to the height of the recessed section. However, in other embodiments, the amount of overlap is greater than or less than the height of the recessed section.

Furthermore, in some embodiments, more than two modular inserts can be stacked on top of each other to further increase the height of the window well. In other embodiments, no window well is used. Instead, two or more modular inserts are combined to make a full-size window well.

For example, in FIG. 37, six modular inserts 3705 are stacked to create a full-size window well 3700. Additionally, all the modular inserts 3705 are the same height and have the same amount of overlap with the adjacent inserts 3705. However, in some embodiments, modular inserts of different heights are stacked together and have different amounts of overlap.

FIG. 38 shows a close-up view of the full-size window well 3700. It should be noted that although the overlap of the modular inserts 3705 is visible from the back of the window well 3700, the transition from one modular insert 3705 to another modular insert 3705 is inconspicuous from the front. In other words, a user viewing the window well 3700 would not easily notice that the window well 3700 is composed of multiple modular inserts 3705.

Additionally, in some embodiments the modular insert can be attached and installed to a window well while the window well remains attached to a structure. For example, a damaged section of the window well may be cut off and replaced with a modular insert. In other words, in order to repair a window well a user can (1) remove a damaged portion of the window well while the window well remains attached to the structure, and (2) replace the damaged portion of the window well with a modular insert which has a recessed section designed to mate with the window well while the window well remains attached and installed to the structure. It should also be noted that the damaged portion of the window well can be replaced by two or more stacked modular inserts.

Additionally, the modular insert can be replaced without detaching the main window well from its corresponding structure. However, in some embodiments the window well or modular insert is removed from the structure before the damage portion is removed and replaced. Overall, the modular insert allows for easy and efficient repairs if the modular insert or the main window well is damaged.

Veil Printing Processes for Molding Thermoplastic Window Wells

In some embodiments, a fabric veil can be used to improve the aesthetics and/or the durability of a fiber reinforced thermoplastic window well. A fabric veil can also be used to improve the aesthetics and/or the durability of a modular insert.

FIG. 39 illustrates an exemplary blank veil 3900. In some embodiments, the veil 3900 is made of a synthetic fabric. For example, the fabric may be polyester, aramid or fiberglass. However, in some embodiments, the veil can also be made from natural fabrics (e.g., linen, cotton, leather or cashmere). Additionally, the thickness of the veil 3900 may vary to accommodate different needs and preferences from 1 mm, 5 mm, 10 mm, 20 mm, 30 mm, 50 mm, 100 mm or more than 100 mm.

In some embodiments, the veil 3900 is compressed into a thermoplastic sheet or sheets during the manufacturing of the lightweight and durable window well. Thus, after manufacturing, the window well has a new outer layer that is composed of the fabric veil that is at least partially embedded into the thermoplastic. In other words, the veil becomes the outer layer of the window well.

In some embodiments, this new outer layer adds strength and integrity to the window well. For instance, the outer layer can improve the strength and durability of the window well and make the surface of the window well less likely to chip or crack. Additionally, in some embodiments, the outer layer can increase the window well's UV light resistance and corrosion resistance. The outer layer can also increase the window well's resistance to various outdoor climates. In other words, the veil can be used to weatherproof (i.e., protect against rain, dust, wind, and/or humidity) the window well.

The outer layer created by the veil can also be used to increase the aesthetics of a window well or modular insert. For example, in some embodiments, the outer layer can be used to hide imperfections caused during the molding process of the window well. The outer layer can also hide unsightly fibers from the thermoplastic. In other words, the outer layer gives a manufacturer more control over the final aesthetics of the exterior of the window well. It should be noted that this level of control over the aesthetics of the thermoplastic product is hard to achieved with traditional manufacturing processes.

The outer layer created by the veil can also be used to add to the overall realism of the organic surface texturing of a window well or modular insert. For example, in some embodiments, a pattern is printed or transferred onto a veil. These patterns can be used to imitate the texture of natural materials. For instance, a veil with a printed pattern can be used to manufacture a window well that has a realistic brick, stone, metal or wood finish. It should be noted that the patterned veils can be used in conjunction with the surface texturing produced by the mold or during post molding operations.

FIG. 40 illustrates some exemplary patterned veils (4000, 4005 and 4010). As seen in FIG. 40, the pattern on the veils can vary to fit the needs and preferences of the manufacturer. For example, some patterns are used to improve the aesthetics of the window well by imitating natural materials or by imitating different surface finishes (e.g., Gloss, Eggshell or Matte).

Additionally, the pattern can be a single color or multiple colors. In other words, the number of colors may vary to accommodate different needs and preferences from 1 color to 2 colors, 3 colors, 4 colors, 5 colors or more than 5 colors.

Once a veil has been chosen, the veil is prepared for the window well manufacturing process. FIG. 41 illustrates one embodiment of a window well manufacturing set-up that implements a veil 4105.

In some embodiments, the veil 4105 is inserted into the mold, below the pre-heated thermoplastic sheet 4110 (with the mold, 1500 and 1600, being raised to approximately 450° F., or at least greater than 385° F. and less than 500° F.). However, in other embodiments, the veil 4105 is place on top of the pre-heated thermoplastic sheet 4110. After placement of the veil 4105 and thermoplastic 4110, the veil 4105 and the thermoplastic 4110 are compressed by the molds.

Overall, the method for manufacturing a window well with a veil comprises (1) heating a fiber reinforced thermoplastic sheet to more than 250° F.; (2) positioning the fiber reinforced thermoplastic sheet, after the heating, within a mold; (3) positioning a veil or multiple veils onto the fiber reinforced thermoplastic sheet; and (4) compressing the fiber reinforced thermoplastic sheet and veil within the mold with a pressure of greater than 200 psi. It will be appreciated that the veil may be used with a variety of different molds (e.g., steel or composite), and/or different materials (e.g., LFRT, GMT or continuous-fiber reinforced thermoplastic).

It should also be noted that in some embodiments, the window well omits a resin for securing the embedded fabric veil to the thermoplastic. In other words, the fabric veil bonds with thermoplastic without any additional bonding agents.

In some embodiments, the veil is placed onto the thermoplastic sheet before the thermoplastic sheet is heated. In other instances, the thermoplastic sheet is heated to greater than 200° F., 300° F., 400° F. or more in a first set of one or more heating and/or compression processes/cycles in the mold before the veil is placed onto the thermoplastic sheet for the final set of one or more heating/compressing processes/cycles.

During molding/compression, the veil 4105 may become embedded into the heated thermoplastic sheet in such a manner that the veil 4105 is physically and visually integrated into the surface of the window well. In other words, the pattern and colors of the veil can become the pattern and colors of the surface of the window well or modular insert. Therefore, as mentioned above, the veil 4105 becomes an outer skin or layer on top of the thermoplastic material which gives the surface a different texture and/or color.

Additionally, in some embodiments, the veil 4105 is embedded below the surface of the window well. In these embodiments, only some of the texturing and/or coloring of the veil 4105 can be seen through the thermoplastic. As a result, the printed pattern of the veil 4105 is only partially visible on the final product surface of the window well.

However, in some embodiments (e.g., when the veil is used only to provide additional strength and durability), the veil is embedded deeper into the window well and cannot be seen through the thermoplastic.

Additionally, in some embodiments, multiple fabric veils are used to manufacture the window well. For example, FIG. 42 illustrates a manufacturing set-up that will produce a window well that comprises of a thermoplastic sheet 4110 and multiple fabric veils, 4105 and 4205. In FIG. 42, one fabric veil 4205 is placed on top of the thermoplastic sheet while another veil 4105 is place below the thermoplastic 4110 sheet. However, in some embodiments, two or more fabric veils are place below the thermoplastic sheet. Similarly, in some embodiments, two or more fabric veils are place on top of the thermoplastic sheet.

When multiple fabric veils are used, the veils can either have matching patterns or each veil can have a unique printed pattern. In other words, multiple veils can be used to combine different patterns to produce more complex patterns. Using multiple veils can also make it easier to give a window well the desired aesthetics, texture and/or properties.

FIG. 43 illustrates a window well 4300 that has been manufactured with the use of a veil. Therefore, the window well 4300 has a patterned outer layer. In FIG. 43, only the front side of the window well 4300 has a patterned outer layer. However, in some embodiments, the pattern of the veil is applied to the front, back, bottom and/or top. In other words, in some embodiments, the veil surrounds the thermoplastic.

Notably, in some instances, no lamination (e.g., no resin) is used for applying/embedding the veil into the window well. It is also noted that the use of a veil to provide a print through function, such as described above, have not heretofore been used with molding thermoplastics without resins. The processing invoked is also different than processes used to mold colored veils to thermoset plastics and/or with the use of resins. Therefore, the manufacturing process is simplified and more efficient than traditional manufacturing methods.

Overall, the disclosed embodiments are directed to veil printing processes for molding thermoplastic window wells or modular insert that greatly improve the ease and efficiency of producing window wells with organic and realistic finishes. Additionally, the quality of the window well aesthetics is much higher as compared to traditional manufacturing methods.

Modular Step for a Window Well

A modular step can be detachably attached to a window well to facilitate climbing in and out of the window well. More specifically, the modular step can be used as a handhold and/or foothold by a person exiting a building through the window well. Additionally, in some embodiments the modular step is accompanied by one or more modular handles to further facilitate entry and egress by means of the window well.

FIG. 44 illustrates a perspective view of one embodiment of a modular step 4400. The modular step 4400 is configured in size and shape to be detachably affixed to a window well. In some embodiments, the modular step 4400 consists of a body 4405 and two flanges 4410. However, in some embodiments, the modular step consists of one or more flanges. Additionally, some embodiments of the modular step have no flanges.

The width, measured from the right side to the left side, of the modular step 4400 may vary to accommodate different needs and preferences from 10 cm to 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, 40 cm or more than 40 cm. Likewise, the height, measured from the end of the first flange to the end of the second flange, of the modular step 4400 may vary to accommodate different needs and preferences, from 8 cm to 9 cm, 10 cm, 12 cm, 14 cm, 16 cm, 18 cm, 20 cm or more than 20 cm. The depth, measure from the frontmost point of the step to the backmost point, of the modular step 4400 may also vary to accommodate different needs and preferences, from 8 cm to 9 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm or more than 30 cm.

In some embodiments, the lightweight and durable window well (see FIG. 1), the modular insert (see FIG. 18) and the modular step 4400 are all manufactured using the same process described above (i.e., heating a thermoplastic sheet and compressing it within a mold or vacuum sealing a thermoset resin). Similarly, the window well, modular insert and modular step 4400 can all be manufactured from the fiber reinforced thermoplastic described above. In other words, the modular step 4400 can be made using LFRT, GMT or any other fiber reinforced plastic that is suitable for high pressure thermoforming. In some embodiments, the material used for the modular step 4400 is a continuous-fiber-reinforced thermoplastic. Additionally, in some embodiments, the modular step 4400 is made using material that is not reinforced by fibers (e.g., plastic, metal or wood).

Additionally, patterns, textures and designs can be added to the modular step 4400 to improve the aesthetics of the modular step 4400. For example, as described above, a patterned veil can be added to the modular step 4400 during the thermoforming process.

Furthermore, in some embodiments, the modular step 4400 is hollow. For instance, FIG. 45 illustrates a back-perspective view of a modular step 4400 with a cavity 4415 on the back. The cavity 4415 can significantly reduce the weight of the modular step 4400. Additionally, in some embodiments, the cavity 4415 allows the modular steps 4400 to stack inside one another. Thus, the modular steps 4400 can be easily stored and transported.

FIG. 46 and FIG. 47 illustrate a front and back view respectively of the modular step 4400. It should be noted that the cavity 4415 is not visible from the front of the modular step 4400. Thus, the cavity 4415 does not detract from the visual aesthetics of the modular step 4400.

Additionally, FIG. 48 and FIG. 49 illustrate a right and left view respectively of the modular step 4400. The flanges 4410 of the modular step 4400 protrude further back than the body 4405. The protruding flanges 4410 allow the modular step to be easily attached to a window well.

FIGS. 50 and 51 illustrate a top and bottom view of the modular step 4400. In some embodiments, the step surface 4420 (i.e., the top surface that a user steps on) is coated with a non-slip coating. The non-slip coating can increase traction and reduce the risk of accidents. The non-slip coating is especially helpful if a user is stepping on the modular step in wet conditions (e.g., rain and snow). In some embodiments, the modular step can also have lights to help the user exit the window well in low light conditions. For example, the modular step can be lined with LEDs that allow a user to locate the step during the night.

FIGS. 52, 53 and 54 illustrate a perspective, front and top view respectively of a modular step 4400 that has been detachably affixed to a window well. In some embodiments, the modular step 4400 may be placed between any two grooves 110. Furthermore, in some embodiments the distance between the modular step and the ground may vary to accommodate different needs and preferences from 15 cm to 30 cm, 45 cm, 60 cm, 75 cm, 90 cm, 100 cm or more than 100 cm.

In some embodiments, one or more flanges create a friction fit with the grooves 110 of the window well when the modular step is mated to the window well. For example, FIGS. 55A and 55B illustrate a cross-section view of a modular step 4400 that has been mated to a window well using a friction fit (i.e., an interference fit or press fit). Additionally, if the window well has a wall thickness that varies (e.g., thicker near the grooves and thinner far from the grooves), then the shape of the flanges 4410 will match the window well's variations in wall thickness. Thus, the modular step 4400 is configured in size and shape to be semi-permanently affixed to a window well.

Additionally, in some embodiments, the two flanges 4410 slightly compress the window well. In other words, the flanges 4410 compress the wall surface portion between the flanges 4410. The compression combined with the friction fit ensures that the modular step 4400 stays firmly attached to the window well. In some embodiments, the modular step 4400 can support up to 90 kilograms (kg) of downward force without detaching from the window well 100. However, in other embodiments, the modular step 4400 can support more than 90 kg of downward force without detaching from the window well.

In some embodiments, one or more mechanical fasteners (e.g., screws or bolts) are used to detachably affixed the modular step to the window well. FIG. 56 illustrates one embodiment of the modular step that has been affixed to the window well using fasteners 5605. The modular step and window well can either be manufactured with slots/holes for fasteners or the user can make the holes after the window well has been manufactured (e.g., with a drill).

Additionally, in some embodiments the modular step has one or more magnets that are used to detachably affix the modular step to the window well. For example, FIG. 57 illustrates one embodiment of the modular step that has 2 internal magnets 5705. Some embodiments of the window well also have corresponding magnets 5710 or magnet anchors (i.e., an attachment point of magnetic metal). Furthermore, in some embodiments the window well is embedded with a material that naturally attracts magnets. Additionally, the number of magnets in the modular step or window well may vary to accommodate different needs and preferences from 1 magnet to 2 magnets, 3 magnets, 4 magnets, 5 magnets, 10 magnets or more than 10 magnets.

The position of the magnets may also vary to accommodate different needs and preferences. For example, in FIG. 57, the magnets are placed along both flanges. Additionally, in embodiments that have a back, the magnets can be place across the back of the modular step between the flanges. In some embodiments, the magnets are placed both on the flanges and on the back of the step between the flanges.

In some embodiments, the flanges 4410 comprise of one or more protruding tabs that facilitate mating with a window well. For example, FIG. 58 illustrates a modular step that has 4 protruding tabs. Additionally, in some embodiments the window well may have one or more slots within the inner rib surface (e.g., along the groove). Thus, the protruding tabs 5805 of the flanges snap into the slots of the window well and create a friction fit when the modular step is attached to the window well.

In some embodiments, the position of the slots and tabs are reverse. In other words, the modular step has one or more slots and the window well has one or more protruding tabs that mate into a friction fit.

Additionally, in embodiments that have a back, the slots/protruding tabs can be placed on the back of the modular step in the area between the flanges. In some embodiments, the inner wall surface of the window well (e.g., between the ribs) has opposing slots/tabs that mate with the slots/protruding tabs on the back of the modular step. More specifically, the slots/tabs on the modular step and the slots/tabs on the window well snap into one another and create a friction fit that locks the modular step into place.

In some embodiments, the modular step is attached to the window well using an adhesive (e.g., glue, cement or epoxy). Additionally, some embodiments use multiple fastening methods (e.g., magnets and a friction fit) to lock the modular step into place.

In some embodiments, multiple modular steps are attached to a window well. For example, FIGS. 59 and 60 illustrate window wells that have multiple modular steps attached. The distance between the modular steps may vary to accommodate different needs and preferences from 15 cm to 30 cm, 45 cm, 60 cm, 75 cm, 90 cm, 100 cm or more than 100 cm. In some embodiments, the distance between modular steps is different within the same window well. For example, the first distance between the modular steps can be 15 cm, while the next distance between the modular steps is 30 cm. The number of modular steps may also vary to accommodate different needs and preferences from 1 step to 2 steps, 3 steps, 4 steps, 5 steps, or more than 5 steps.

Additionally, FIG. 61 illustrates a window well that has modular steps attached to one side of the window well. In some embodiments, modular steps can be attached to both sides of the front of the window well. Therefore, two users can climb out of the window well at once.

FIGS. 62 through 65B illustrate 7 different views of a second embodiment of the modular step 6200. The second embodiment of the modular step 6200 includes a recess 6205 that facilitates climbing. For example, the recess 6205 improves a user's grip by allowing her fingers to wrap around the modular step 6200 more fully. Additionally, the recess 6205 also lowers the chances that a user's foot will slip during climbing by providing a ledge for the foot to rest on.

FIGS. 66 through 69B illustrate 7 different views of a third embodiment of the modular step 6600. The modular step 6600 comprises of a rectangular rung 6605 and two connection arms 6610. When the modular step 6600 is mounted to the window well, the rung 6605 is separated from the window well, such that a space exists between the window well and the rung 6605 of the modular step. Thus, this embodiment can further facilitate a user's ability to grab ahold of the modular step 6600 during use. Additionally, in some embodiments the connection arms 6610 are in a general C-shape and have attachment holes 6615. The attachment holes 6615 facilitate the mating of the modular step 6600 to the window well.

FIG. 70 illustrates a fourth embodiment of the modular step 7000. The modular step 7000 is similar to the previous embodiments 6600. However, the modular step 7000 does not have attachment holes.

FIG. 71 illustrates a fifth embodiment of the modular step 7100. The modular step 7100 has connection arms that are more square-shaped than the previous embodiments. Similarly, FIG. 72 illustrates a sixth embodiment of a modular step 7200 with generally square-shaped connection arms. However, in the sixth embodiment, the rung is lower on the connection arm than in the previous embodiments. Additionally, FIGS. 73, 74A and 74B illustrate 3 views of a seventh embodiment of a modular step 7300. The modular step 7300 has a circular rung and generally V-shaped connection arms.

All the previous embodiments of the modular step are approximately the same size. Additionally, all the modular steps can be attached to the window well using the variety of methods described above (e.g., mechanical fasteners, magnets, friction fits and adhesive). The embodiments can also be made of a variety of materials (thermoplastic, synthetic plastic, natural plastic, metal or wood). It should also be noted that all the embodiments of the modular steps can be used both as handholds and as steps. For example, a person can grab a modular step at the top of the window well with her hand while simultaneously stepping on a modular step attach to the bottom of the window well.

Additionally, in some embodiments one or more modular handles can be attached to the window well. FIGS. 75 and 76 illustrate one embodiment of a modular handle 7500 that is configured in size and shape to be detachably affixed to a window well. Like the modular step, the modular handle 7500 can help users climb in and out of a window well. Some embodiments of the modular handles 7500 have the same fastening methods (e.g., interference fit, screws/bolts, protruding tabs) and manufacturing process (e.g., thermoforming) as the modular steps. Additionally, some embodiment of the modular handle 7500 are made of the same material as the modular steps (e.g., thermoplastic, synthetic plastic, natural plastic, metal or wood). Additionally, in some embodiments, the modular step and the modular handle 7500 are designed to match the structure and design of the window well.

Furthermore, the width of the modular handle 7500 may vary to accommodate different needs and preferences from 2 cm to 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 15 cm or more than 15 cm. Likewise, the height and depth of the modular handle 7500 may vary to accommodate different needs and preferences from 6 cm to 7 cm, 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 30 cm, 35 cm or more than 35 cm.

In some embodiments, the modular step and modular handle 7500 can be attached and detached while the window well is installed and attached to a building structure. Therefore, a user can customize the window well with the modular steps and/or modular handles 7500 to a configuration which the user prefers. For example, the user can change the number of modular steps and/or modular handles 7500 that are attached to the window well at any time. Similarly, a user can easily change the locations of the modular steps or modular handles 7500 (e.g., from the middle of the window well to the side of the window well) by detaching the modular step or modular handle and reattaching it in the desired location. Thus, a user can customize a window well with one or more modular steps and/or one or more modular handles 7500.

In conclusion, the disclosed embodiments allow a user to easily install or remove modular steps from a window well, since the modular steps are configured in size and shape to be detachably affixed to window wells. The user can also choose the location and number of modular steps to facilitate entry into and exit out of their window wells. Thus, the modular steps can improve both the safety and visual aesthetics of window wells.
