Abstract
An extruded, seamless and weld-free, loop of flexible material for use as a coil in an airbed. The extruded coil provides more strength and no weak points for coils, and thus a more stable, durable, airbed. In addition, the process of using an extruded coil allows for less manufacturing deviation, and thus a more consistently durable airbed. The extruded coils may be textured inside and out to allow for ease of assembly, and to keep the coils from sticking during inflation and deflation of the product.
Description
- The present invention is directed to airbeds, and more specifically to reinforcing structures for airbeds.
- An airbed is a large rectangular rubber or plastic bag that is filled with air so that it may be used as a bed. Airbeds are well known in the art and have proven themselves to be very useful. On the one hand, when there is no need to sleep on an inflatable airbed, an owner may simply deflate the airbed (i.e., let all the air out), fold it up, and then store it away in a closet or basement. On the other hand, when guests arrive or when the owner of the airbed takes a trip to a place where there is no bed, the owner may simply inflate the airbed and sleep on it.
- Most current inflatable airbeds have a single chamber, meaning that air can travel anywhere inside the airbed since there is no barrier sealing off one portion of the airbed from another. Therefore, when multiple people sleep or sit on the airbed, air is constantly being moved from one portion of the airbed to another as the weight of the person is shifted.
- For example, suppose person A is sleeping on the left side of an inflated queen size airbed. Because there is currently no weight on the right side of the airbed, air would naturally flow toward the unweighted right side of the airbed until an equilibrium pressure condition is established (i.e., the right side cannot hold anymore air). This shifting of air to the right side consequently would cause the right side of the airbed to rise.
- Next, suppose person B wants to sleep on the now elevated right side of the airbed. As person B descends onto the right side of the airbed, this new weight causes a redistribution of the air back toward the left side of the airbed where person A is sleeping. Air flows back to the left side of the air bed, causing the left side to rise due to the newly added air pressure underneath. This unexpected elevation in the left side of the airbed may even awake person A. Furthermore, each time person A or B moves around during their sleep and causes a shift in weight on the airbed, air may also be shifted around inside the entire airbed. This constant movement of air inside the airbed in response to weight shifts causes different portions of the airbed to rise and fall until the weight movement stops. This constant rocking, elevation or depression of various portions of the airbed every time one person moves can disrupt a good night's sleep.
- To address the unequal distribution of air in an airbed, a variety of different constructions have been used to control the structure and shape of airbeds. A first type is an internal I-beam structure, having a material that extends from an interior of a top wall of an airbed to an interior of a bottom wall of the airbed. This structure is designed in such a way to consist of well defined start and stop points, the start and stop points attached to the inner surfaces of the airbed. The I-beam prevents portions of the airbed adjacent to the I-beam from rising beyond a certain height. However, I-beams are inherently weak because of the start and stop points.
- An improvement to the I-beam construction is the concept of coil designs. Coils allow for an effectively closed loop to be attached at upper and lower portions of the loop to the interior portions of the upper and lower walls of the airbed. Because a loop is used, there are effectively no start and stop points in this design. Thus, this structure greatly improves the performance and durability of an airbed.
- The most commonly used coils in contemporary airbeds are formed by taking two flat sheets of material and butt welding the edges of these materials together, forming a tube. The butt welded tube is then heat welded to the top and bottom walls of the airbed with ellipse-like welds. It has been found that the ellipse-like welds and other discretely shaped welds, such as circular, triangular, or rectangular-shaped welds, provide users with more comfort than a rigid, narrow weld, such as a standard I-beam-type weld. Moreover, the ellipse-like welds also allow for optimal strength characteristics in bonding of the coils.
- Such a structure is shown in
FIG. 1 , where anairbed 10 includescoils 12 havingbutt welds 14 at top and bottom edges.Oval welds 16 are utilized to connect thecoils 12 to upper and lower walls of theairbed 10. Thebutt welds 14 are contained within and extend perpendicular to theoval welds 16. Thebutt welds 14 are not strong enough to maintain a permanent connection of thecoil 12, and thus serve as a temporary, end-process weld that holds thecoil 12 together until thecoil 12 is attached to the upper and lower walls of theairbed 10 by theoval welds 16. Theoval welds 16 then hold the two ends in place. - One problem with the design shown in
FIG. 1 is that thebutt weld 14 can become a weak spot for the attachment of thecoil 12 to theoval weld 16. Thus, thebutt weld 14 can reduce the durability of the airbed. - The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
- In accordance with an embodiment, an extruded, seamless and weld-free, loop of flexible material is provided for use as a coil in an airbed. The extruded coil provides more strength and no weak points for coils, and thus a more stable, durable, airbed. In addition, the process of using an extruded coil allows for less manufacturing deviation, and thus a more consistently durable airbed.
- In accordance with an embodiment, the extruded coils may be textured inside and out to allow for ease of assembly, and to keep the coils from sticking during inflation and deflation of the product.
- Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:
-
FIG. 1 shows a side perspective view of a prior art airbed; -
FIG. 2 shows a side perspective view of an airbed incorporating coils in accordance with an embodiment of the present invention; -
FIG. 3 is a cross-sectional view taken along the section lines 3-3 ofFIG. 2 ; and -
FIG. 4 is a diagrammatic view representing a method by which an extruded coil may be produced in accordance with an embodiment. - In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
- Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,
FIG. 2 shows a side perspective view of anairbed 20 incorporatingcoils 22 in accordance with an embodiment. Briefly described, thecoils 22 are formed of a single-piece, seamless, weld-free, extruded flexible tube of material. - The
coils 22 are attached to upper andlower walls airbed 20 byoval welds 28. Althoughoval welds 28 are shown in the drawings, other welds may be used, including any type of ellipse-like weld, such as circular, triangular, or rectangular shaped welds, or more narrow welds. In addition, although a single weld is shown for attaching acoil 22 to theupper wall 24 and another, singleoval weld 28 is shown as attaching thelower wall 26 to thecoil 22, two or more welds may be used at the attachment of thecoils 22 to the upper and/orlower walls - In the embodiment shown, the
coils 22 are provided as short segments, and a series ofcoils 22 are provided along the length of theairbed 20. However, in an alternate embodiment,longer coils 22 may be provided, having multipleoval welds 28 or similar welds for attaching theelongate coils 22 to the upper andlower walls coils 22 may extend almost the length of theairbed 20, and may be attached by multipleoval welds 28 or similar welds along the length of thecoils 22. - The
coils 22 may be cut to proper length, or may be provided by a supplier at a desired length. Thecoils 22 are then welded in a manner known in the art to the upper andlower walls coils 22 provide structure for theairbed 20, as can be seen inFIG. 3 . Thecoils 22 prevent movement of the upper andlower walls coils 22. - In accordance with an embodiment, the
coils 22 are made of polyvinylchloride (PVC). However, any suitable material may be used. PVC, however, is typically the material used for airbeds, such as theairbed 20, and thus provides quick and easy welding to the upper andlower walls - The method for making extruded polyvinylchloride flexible tubes is known, but a process is shown in
FIG. 4 for the benefit of the reader. Anextrusion mold 30 is utilized for forming an elongate,flexible extrusion 32. Theextrusion mold 30 includes anouter dye 34 and aninner dye 36. Theelongate extrusion 32 is extruded from between theouter dye 34 and theinner dye 36. - During the extrusion process, it is important to keep the sides of the
elongate extrusion 32 from touching one another so that they will not weld together before cooling. To this end, an internal cooling airstream, indicated by thearrows 38 may be provided for the cooling and separation of theelongate extrusion 32. In addition to or in replacement of theinternal cooling airstream 38, a vacuum, such as viavacuum boxes 40 may be supplied on the outside of theelongate extrusion 32, for pulling the walls of theelongate extrusion 32 apart. Theinternal cooling airstream 38 and/or thevacuum boxes 40 may extend an appropriate length beyond theextrusion molds 30 so that theelongate extrusion 32 is cooled when it is no longer supported by theinternal cooling airstream 38 and/or thevacuum boxes 40. - The
coils 22 of the present invention provide a stable structure for an airbed, such as theairbed 20. Thecoils 22, because they are formed of an extruded material, do not include butt welds or any other potentially weak locations. - If desired, the
coils 22 may be textured on the inside and outside to allow for ease of assembly. Texturing would also prevent thecoils 22 from sticking during the inflation and deflation of theairbed 20. - The use of the extruded coils 22 permits coils to be produced with less manufacturing deviation. As such, the size of the
coils 22 is more consistent, providing a more consistentlydurable airbed 20. - Other variations are within the spirit of the present invention. Thus, while the invention is susceptible to various modifications and alternative constructions, a certain illustrated embodiment thereof is shown in the drawings and has been described above in detail. It should be understood, however, that there is no intention to limit the invention to the specific form or forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention, as defined in the appended claims.
