TECHNICAL FIELD
This disclosure is related to a polymerized adapter for channeling an airflow, in particular a compact and portable device for the evacuation of air from vacuum bags or other containers, including ancillary devices that may be used with commonly available devices and equipment to adapt those devices for such evacuation.
BACKGROUND
The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art.
Vacuum bags for compacting clothing and other articles for storage or transport are commonly available in various sizes and configurations. One of the most common methods to evacuate the air from these bags, compacting the contents, is the use of an ordinary and widely available vacuum cleaner, attaching the hose thereof to the valve of the vacuum bag. This works well in cases in which the user is at home, or otherwise has access to a vacuum cleaner. However, when traveling, users seldom have access to a vacuum cleaner, and generally are obliged to evacuate as much air as possible by rolling the vacuum bag tightly to evacuate as much air as possible, but, in the process, causing the bag and its contents to become distorted and wrinkled, reducing the effective volume by less than would be optimal.
SUMMARY
A vacuum adapter device is useful for connecting a suction generating device to a garment bag. The device includes at least one conical section. the conical section includes a wide opening configured be connected to one of the suction generating device and the garment bag and a narrow opening connected to a reinforcing feature configured to prevent the narrow opening from collapsing when suction is applied to the device. The conical section is constructed with a flexible polymer material.

DETAILED DESCRIPTION
The present invention encompasses improvements to the prior art, by providing a simple and elegant design lending itself to very economical manufacturing means, providing a broadly adaptable interface with vacuum bags, enabling it to the used with most all of the available vacuum bags, and providing for easy collapse and compaction for transport.
With the present invention, any number of available hair dryers may be used to evacuate almost any of the vacuum bags currently available for purchase by consumers. It comprises a compact, flexible unit that is easily collapsed for inclusion in a traveler's luggage with a minimum of space requirement, and may be used to evacuate any number of air-containing vessels, including air mattresses.
Most hotels include a hair dryer in the hotel room for use by guests. While these hairdryers are intended primarily to blow air, heated to various levels, in order to dry the hair of guests after washing, they must draw air into the unit for that purpose. The intake is generally on the end of the hairdryer, and is defined on a surface that is round, oval or rectangular. The present invention is capable of functioning with all of these surfaces, being sufficiently flexible to conform to the various shapes, while being sufficiently stiff to maintain the opening connecting the hair dryer (or other device) to the vacuum bag valve. Moreover, in the preferred embodiment, the Adapter is capable of sealing interface with a variety of vacuum bags and vacuum bag valve designs, wherein a smaller cone defined on the opposite end of the Adapter from the conical section that conforms to the hair dryer of other device is sufficiently flexible, owing to a thinner section thickness, to readily conform, in response to the vacuum, to the surface of the vacuum bag surrounding the vacuum bag valve, whenever the shape and size of the vacuum bag valve is such that the end of the cylindrical section does not adequately seal on the internal or external diameter of the vacuum bag valve opening.
As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various and alternative forms. The accompanying drawings are not necessarily to scale, and some features may be exaggerated or minimized to show details of particular components or features. Therefore, specific structural or functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Referring now to the drawings, wherein the numerals refer to like of corresponding parts throughout the several views, the present invention is generally characterized as an adapter, comprising a single, unitary molded item, in which a larger conical section is connected to a smaller section by a cylindrical section, completing an adapter whose larger conical section is designed to conform to the intake end of most hair dryers, and drawn into sealing contact with such hair dryer by the vacuum created by the air-moving portion of the hair dryer. The end of the cylindrical section at its intersection with the smaller conical section is of such size and shape to allow it to fit snugly with the termination of the valve of most vacuum storage bags. The smaller conical section is of such size and wall thickness as to allow it to be drawn sealingly to the surface of a vacuum storage bag surrounding the valve by the vacuum, effecting a functional seal even in those cases wherein the cylindrical termination does not adequately seal to the termination of the valve.
Adapter devices are disclosed for use connecting a hair drier device or other suction creating device to a garment bag. The suction created by the attached device pulls air through the adapter from the garment bag. The adapter device includes at least one conical section with flexible walls in the conical section which accommodates sealing to one of the hair drier device and garment bag or the valve portion of the garment bag. The adapter device, in addition to the at least one flexible conical section includes at least one reinforced portion configured to provide structure to the at least one conical section and prevent the device from collapsing upon itself as the suction is applied to the garment bag through the adapter. The reinforced portion can include a cylinder shaped portion with a reinforcing feature preventing the cylinder shaped portion from deforming in response to suction being applied to the adaptor.
Referring now to the drawings, wherein the showings are for the purpose of illustrating certain exemplary embodiments only and not for the purpose of limiting the same, FIGS. 1-3 illustrate an exemplary vacuum adapter device in a perspective view, including a first conical section configured to attach to a hairdryer and a second conical section configured to attach to a garment bag valve portion. Adapter device 10 is illustrated. Small conical section 1 is illustrated connected to an intersection 2 with the cylindrical section, 4. The cylindrical section, 4, is shown connecting also connecting to larger conical section 5. According to one embodiment of the disclosure, section thickness of the material of cylindrical section 4 can be greater than the section thicknesses, 6 and 7, of either of the two conical sections, 5 and 1, respectively. In one embodiment, section thicknesses 6 and 7 can be kept relatively thin, such that the thin material of the two cone shapes can easily comply to a mating surface upon a connecting hairdryer and a mating surface around a valve portion of a garment bag. While it can be preferable for the cone sections to be pliable, it can also be preferable that cylindrical section 4 be resistant to deformation when a lower pressure or suction is applied within the device. This rigidity of cylindrical section 4 ensures that the suction applied by the hairdryer is useful to draw air from the garment bag. The increased thickness of cylindrical section 4 is one way to accomplish this rigidity. Other exemplary methods to increase the rigidity of cylindrical section 4 include forming annular ribs in the material of the cylindrical section 4, molding a plastic ring within cylindrical section 4, or molding a disk with through holes within cylindrical section 4. Each of conical sections 1 and 5 include wide openings configured to attach to one a suction generating device such as a hair drier and a valve portion of a garment bag. Each of conical sections 1 and 5 include narrow openings connected to a reinforced portion configured to prevent the narrow openings from collapsing when a suction is applied to the adapter device.
In FIG. 2, the adaptor 10 is shown viewing from the end with the smaller conical section, 1, with the numbers corresponding as in FIG. 1. Thickness 7 of smaller conical section 1 can be the same as thickness 6 of the larger conical section 5. In another embodiment, thickness 6 can be greater than the thickness 5. Internal diameter 3 of the cylindrical section 4 is illustrated in FIG. 2. Now referring to FIG. 3, adapter device 10 is illustrated, including a lateral section view showing in clearer detail the relative sizes of the two conical sections, 1 and 5, and the relative section thicknesses of the larger conical section, 6, the section thickness of the smaller conical section, 7, and the section thickness, 8, of the cylindrical section, 4.
The adapter may be constructed without the smaller conical section if it is desired to have it specialized and usable with vacuum bags with the same or very similar valve terminations, as might be the case if provided by the vacuum bag manufacturer or distributor with or as an option for that manufacturer's product.
FIG. 4 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a conical section and a reinforced cylindrical section. Adapter device 100 is illustrated. Conical section 105 is illustrated connected to an intersection with the cylindrical section 104. The cylindrical section, 104, includes a thickness 106 which is wider than thickness 106 of conical section 105. The relatively wider thickness 106 of section 104 reinforces section 104. The relatively thinner thickness 106 of section 105 permits section 105 to deform and conform to a surface of one of a hair drier intake portion or a garment bag surface or valve.
FIG. 5 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a first conical section, a second conical section, and a cylindrical section joining the two conical sections, wherein the cylindrical section includes annular ribs around an outer circumference in order to reinforce the cylindrical section.

The cylindrical section, 204, includes a similar or same thickness of conical sections 205 and 201. Annular rings 209 formed on an outer surface of cylindrical section 204 reinforce section 204 and prevent section 204 from collapsing when suction is applied through adapter 200.
FIG. 6 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a conical section and a cylindrical section, wherein the cylindrical section includes annular ribs around an outer circumference in order to reinforce the cylindrical section and a garment bag interface feature. Adapter device 300 is illustrated. Conical section 305 is illustrated connected to an intersection with the cylindrical section 304. The cylindrical section, 304, includes a similar or same thickness of conical section 305. Annular rings 309 formed on an outer surface of cylindrical section 304 reinforce section 304 and prevent section 304 from collapsing when suction is applied through adapter 300. Cylindrical section 304 includes interface features 301 configured to connect and seal to features 312 of garment bag valve 310.
FIG. 7 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a first conical section, a second conical section, and a cylindrical section joining the two conical sections, wherein the cylindrical section includes a molded-in ring to reinforce the cylindrical section. Adapter device 400 is illustrated. First conical section 405 and second conical section 401 are each illustrated connected to an intersection with the cylindrical section 404. First conical section 405 includes a relatively narrower conical shape than the conical shape of second conical section 401. The cylindrical section, 404, includes a similar or same thickness of conical sections 405 and 401. A polymer ring 409 is molded-in within the material of section 404. The rigidity of polymer ring 409 prevents the cylindrical section from collapsing when suction is applied to adapter 400. Ring 409 can be exposed to an inner or outer surface of adapter 400, or ring 409 can be entirely within the material of adapter 400 such that the ring is not visible from an outside of the adapter.
FIG. 8 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a conical section and a cylindrical section, wherein the cylindrical section includes a molded-in disk including through holes in order to reinforce the cylindrical section. Adapter device 500 is illustrated. Conical section 505 is illustrated connected to an intersection with the cylindrical section 504. A polymer disk 509 with through holes 510 is molded-in within the material of section 504 and reinforces section 504.
FIG. 9 illustrates the disk including through holes from FIG. 8. Disk 509 is illustrated including two exemplary through holes 510 and outer surface 511. Surface 511 or any other surface of disk 509 or of ring 409 of FIG. 7 can include grooves or texturing to improve retention of the reinforcing feature to the mating material of a vacuum adapter device.
FIG. 10 illustrates an additional exemplary embodiment of a vacuum adaptor device, which includes a first conical section, a second conical section, and a cylindrical section joining the two conical sections, wherein interior surfaces of the cone shapes intersect within the two conical sections resulting in a triangular cross section within the cylindrical section. Adapter device 600 is illustrated. First conical section 605 and second conical section 601 are each illustrated including interior conical shapes 603 and 602, respectively. A cylindrical section 604 is illustrated on an outside surface of device 600. Interior conical shapes 603 and 602 intersect within section 604 to form a triangular cross-section 609 within cylindrical section 604. The triangular cross-section 609 provides increased rigidity as compared to flat walls of the conical sections and prevents the cylindrical section from collapsing when suction is applied to adapter 600.
FIG. 11 illustrates the vacuum adapter device of FIG. 1 being used in conjunction with an exemplary hair drier device to remove air from an exemplary garment bag.
