The present invention relates generally to improvements in systems for drying personal protective equipment, and more specifically to systems for drying protective turnout gear worn by firefighters.
Personal protective equipment often gets wet for a variety of reasons and needs to be dried. Specifically, personal protective equipment gets wet whenever it is washed and may require a system specifically designed for protective equipment to be properly dried.
For example, firefighter turnout gear is washed by putting the gear into a bath and thoroughly soaking and rinsing the gear. After washing, the turnout gear is difficult to quickly and properly dry due to the bulk and design of the gear. As a result of ineffective drying, turnout gear may mildew or mold or otherwise be harmed, which decreases the effectiveness of the gear. Furthermore, because turnout gear may still be wet when it is next needed by a firefighter, firefighters are less likely to wash their turnout gear. Therefore a drying system specifically suited for drying protective equipment is needed.
Modern drying systems specifically for protective equipment are available but have certain shortcomings. To ensure that protective equipment is properly maintained and dried, thereby ensuring the integrity of the equipment, there is a constant need for improvement in functional aspects of such equipment drying systems.
The novel features believed characteristic of the embodiments of the present application are set forth in the appended claims. However, the embodiments themselves, as well as a preferred mode of use, and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:
While the assembly and method of the present application is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular embodiment disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present application as defined by the appended claims.
Illustrative embodiments of the drying system according to the present application are provided below. It will of course be appreciated that in the development of any actual embodiment, numerous implementation-specific decisions will be made to achieve the developer's specific goals, such as compliance with assembly-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

Frame assembly 103, according to the preferred embodiment of the present application, is made of several sub-components, including straight ducting frame segments 105, bent ducting frame segments 107, and ducting junctions 109, 111, 113. Frame segments 105 and 107, and junctions 109, 111, 113 direct air from blower 119 through frame assembly 103 and valves 123, 125 to ventilated garment racks 115 and ventilated gear racks 117, 501. Blower 119 is connected to frame assembly 103 through junction 109, valves 123 are connected at junctions 111, and valves 125 are connected at junctions 113. The sub-components of frame assembly 103 are preferably made of durable and corrosion-resistant materials, such as stainless steel, aluminum, polymer, or composites. Frame components may have surface treatments applied to increase their durability and corrosion resistance, such as painting, powder coating, or other treatments. In some embodiments, sub-components may be commonly available parts like PVC pipe lengths and fittings, or metal pipe or conduit and fittings.
The sub-components of frame assembly 103 preferably are attached to each other by some type of removable coupling method, such as flange couplings, threads formed in the sub-components, or dimensioning the sub-components such that they may be held together by friction. Due to the use of such sub-components and coupling methods, frame assembly 103 may be easily modified, reconfigured, or assembled to extend or reduce the length of frame assembly 103 and easily add or remove junction 111, 113 in the event that a user wishes to have more or fewer than the preferred number of ventilated garment racks 115 and ventilated gear racks 117.
Frame assembly 103 and other attached features are supported by and attached to a rolling base assembly 127 according to the preferred embodiment in the present application. Rolling base assembly 127 generally comprises a hollow base 129, casters 131, frame mounts 133, base-mounted bracing 135, a blower seat 137, at least one grate 139, a drain 141, a base valve 143, and at least one opening 145 in the top surface of hollow base 129. The features of rolling base assembly 127 are preferably made of durable and corrosion-resistant materials, such as stainless steel, aluminum, polymer, or composites. These features may have surface treatments applied to increase their durability and corrosion resistance, such as painting, powder coating, or other treatments. However, other material and material treatment choices may be made depending on the needs and demands of the desired application of gear dryer 101.
Hollow base 129 is generally a rectangular shape, having four sides, a top, and a bottom. Openings 145 are formed through the top surface of hollow base 129. According to the preferred embodiment in the present application, openings 145 allow any runoff or drips from protective equipment drying on ventilated garment racks 115 to fall into and be captured by hollow base 129. Openings 145 are covered by and support grates 139. Grates 139 catch debris or other objects that fall from racks 115 above and from equipment drying on racks 115.
According to the preferred embodiment in the present application, base assembly 127 contains a plurality of openings 145, and an equal number of grates 139 covering openings 145. As illustrated in
According to the preferred embodiment in the present application, hollow base 129, as well as openings 145 and grates 139, extends at one end only to a first end of frame assembly 103, thereby not providing for the capture of any runoff or drips from gear racks 117, 501. In alternative embodiments, base 129, as well as openings 145 and grates 139, may extend beyond the first end of frame assembly 103 (not shown) in order to capture runoff or drips from equipment on gear racks 117, 501. Gear racks 117, 501 may also alternatively face inwards on frame assembly 103 (not shown) such that they are located above openings 145 and grates 139 when base 129 only extends on one end to the edge of frame assembly 103.
Hollow base 129 has frame mounts 133 and base-mounted bracing 135 fixed on its top surface. Frame mounts 133 and bracing 135 support and retain frame assembly 103. As shown, frame mounts 133 are simple pockets into which the lower ends of frame assembly 103 fit, allowing frame assembly 103 to be easily removed from frame mounts 133 for maintenance or transport. It should be understood though that, according to the preferred embodiment or the present application, frame mounts 133 may be any form of frame mounting design, such as pockets, flanged couplings, or mounting points which allow frame assembly 103 to be bolted or otherwise attached to base assembly 127. Base-mounted bracing 135 preferably extends upwards from hollow base 129, and secures and orients frame assembly 103 as seen in
As illustrated, bracing 135 consists of multiple curved arms extending upwards and clamping around frame assembly 103, but it should be understood that bracing 135, according to the preferred embodiment in the present application, includes any form of bracing that extend between hollow base 129 and frame assembly 103. Other gear dryer embodiments may use wall-mounted bracing to secure a frame (see
Hollow base 129 has a blower seat 137 on its top surface. Blower seat 137 retains and orients blower 119. Blower seat 137, according to the preferred embodiment in the present application, may be a recess formed in the top of hollow base 129, or may be a pocket formed by bracing mounted on top of hollow base 129, or may be a combination thereof. In the preferred embodiment, air from blower 119, though primarily directed into frame assembly 103, may also be selectively directed into hollow base 129 through base valve 143. Base valve 143 may be part of a frame mount 133, or may be a separate component attached to and between frame mount 133 and frame assembly 103. Base valve 143 may be a ball valve or butterfly valve. Rolling base assembly 127 may include only one base valve 143 as shown in
By directing air into hollow base 129, blower 119 and base valve 143 allow ventilation to help dry any fluids held in hollow base 129. When blower 119 is set at a higher flow rate, air may actually vent through hollow base 129 and up through grates 139 to provide additional ventilation to equipment hanging above on garment racks 115. Hollow base 129 may at times accumulate a greater volume of fluid than can effectively be dealt with by directing ventilation into base 129. As such, a drain 141 is fitted to hollow base 129. According to the preferred embodiment in the present application, drain 141 is a selectively-opened garden hose type faucet. Drain 141 may therefore empty fluids from base 129 directly onto the floor beneath gear dryer 101, or to empty fluids to a remote location with the use of a common garden hose. In other embodiments, drain 141 may be some other type of faucet or valve, or may be a simple opening and plug.
Rolling base assembly 127 contains a plurality of casters 131 attached to the bottom of hollow base 129. Casters 131 preferably are heavy-duty type casters designed for rolling on flat hard surfaces such as shop or garage floors and contain some form of locking mechanism so that the wheels of casters 131 may be selectively locked and unlocked. As such, gear dryer 101 may be easily moved and repositioned when necessary, and may be secured into a stationary position once in place. Other embodiments of a base assembly may contain all-terrain type casters (see
Gear dryer 101 preferably has a plurality of ventilated garment racks 115 and ventilated gear racks 117, 501, to which air is supplied by blower 119. According to the preferred embodiment in the present application, blower 119 may circulate simply circulate environmental air, or may be equipped with a heating element to supply heating ventilation through frame assembly 103 to ventilated racks 115 and 117, 501. Blower 119 may have at least one filter to clean particulates and contaminants from the environmental air. Blower 119 may be configured to also add disinfecting or odor fighting substances to the ventilation supplied to ventilated racks 115 and 117, 501. Alternative gear dryer embodiments may instead only use a blower to circulate air, and may place any combination of heating elements, filters, and substance dispersal implements anywhere within or on the frame assembly. Blower 119 preferably has control functions such as automatic timers, cycle alerts, temperature control settings, or selectable flow rate.
Blower 119 is connected to junction 109 of frame assembly 103 through blower duct 121. As illustrated, blower duct 121 is a rigid piece of straight tubing positioned perpendicular to frame assembly 103. Blower duct 121 though should be understood to include any kind of rigid or flexible ducting between blower 119 and frame assembly 103, and may be positioned and oriented at any angle and along any length. For example, in an alternative embodiment, a blower duct 1521 is illustrated as being a length of flexible ducting that allows a blower 1521 to be positioned at any angle and location relative to gear dryer 1501.
Gear dryer 101 has at least one, and preferably a plurality of, gear racks 117, 501 mounted along one end of frame assembly 103. Referring now to

In other embodiments of gear dryers, garment racks may be configured in a variety of ways not shown, and may use any arrangements and combinations of rigid ventilated tubes and flexible ventilated tubes. Other gear dryer embodiments may use any number of and combination of various garment rack embodiments arranged and oriented in any way.
A benefit of the preferred gear dryer 101 embodiment according to the present application is that each ventilated garment rack 115 and ventilated gear rack 117 has its own corresponding valve 123, 125, respectively. Valves 123 and 125 preferably are ball valves. Referring now to
Valves 123 and 125 preferably are attached to racks 115, 117, 501 and junctions 111, 113 by some removable coupling method such as flange couplings or threads formed in portions of racks 115, 117, 501, valves 123, 125, and junctions 111, 113. Valves 125, junctions 113, and racks 117, 501 may also simply being dimensioned such that friction between the parts holds them together. In other embodiments, valves 123, 125 may be connected to racks 115, 117 and junctions 111, 113 permanently with methods such as the use of adhesive, screws, bolts, or welding.
