Abstract

A transportable or hand carriable forced air dryer for boots, gloves and facepieces such as gas masks and other headpieces with attached drinking tubes. A pair of manifolds having spaced parallel tubes extend in opposite directions from a blower housing/plenum structure. Each manifold has plural spaced upstanding air discharge tubes. Each air discharge tube has attached thereto a form expander in looped form extending in spaced parallel arrangement and terminating beyond the air discharge to prevent air blockage by the article to be dried. One manifold is permanently connected and the other is quick connected and quick disconnected, without tools for field reassembly. For transport, the released manifold is inverted and nested on the permanently connected manifold for compact installation in a tote bag. The air discharge tubes are provided with a nipple sized and threaded to receive thereon a standard military canteen cap having a reduced size nipple thereon for connection to a drinking tube of a gas mask disposed for drying on an adjacent air discharge tube.

Claims

1. A transportable forced air dryer for articles of apparel comprising:

(a) a blower housing including a blower therein;

(b) structure defining a plenum chamber attached to the blower housing and operative to receive in the plenum chamber forced air from the blower and including a first and second set oppositely directed air discharge ports;

(c) a first and second manifold, each including a pair of spaced generally parallel tubes each having an open end and a closed end, wherein the open end of each pair of tubes is attached to a mounting member, wherein the mounting member for the pair of tubes of the first manifold is non-removably attached to the blower plenum with the respective open ends of the pair of tubes communicating with the first set of air discharge ports; and

, the mounting member of the second manifold is releasably quick-connected to the blower plenum with the respective open ends of the pair of tubes communicating with the second set of air discharge ports;

(d) a plurality of air discharge tubes disposed on each of the generally parallel tubes and having an end thereof receiving forced air therefrom;

(e) a form expanding member for an article to be dried disposed adjacent each air discharge tube in spaced generally parallel relationship thereto for preventing an article received over the respective air discharge tube from blocking air discharge therefrom; and

,

(f) a first end support member non-releasably attached to the ends of the pair of tubes of the first manifold distal the mounting member; and

, a second end support member releasably quick-connected to the ends of the pair of tubes of the second manifold distal the mounting member, wherein upon quick-disconnect of the second mounting member of the second manifold from the blower plenum, wherein the second manifold is operative to be inverted and nested on the first manifold with the respective discharge tubes and form expanding members of the first and second manifolds closely interdigitated for compactness of packaging in a container.

2. The dryer of claim 1, wherein the blower plenum includes a pair of spaced mounting lugs and the second manifold mounting member includes a pair of slots correspondingly spaced for slidably engaging and disengaging the lugs for effecting quick connect and disconnect of the second manifold.

3. The dryer of claim 1 further comprising a nipple releasably disposed over an end of a discharge tube adjacent a discharge tube having a facepiece received thereon for drying, wherein the nipple is configured to receive a canteen cap thereon for connection to a drinking tube attached to the facepiece for separately discharging air into the drinking tube.

4. The dryer of claim 3, wherein the air discharge fitting on the nipple includes a threaded portion for connection to a canteen cap.

5. The dryer of claim 1, wherein the first and second mounting members comprise a thin plate member having a stiffening flange formed on an edge thereof.

6. The dryer of claim 1, wherein each of the form support members comprises a wire loop attached to each of the respective air discharge tubes.

7. The dryer of claim 1, wherein the mounting plate of the second manifold includes a hooked flange releasably engaging an edge of the plenum structure for effecting the quick connect and disconnect.

8. The dryer of claim 1, wherein the form expanding member extends vertically beyond the air discharge tube.

9. The dryer of claim 1 further comprising a nipple sized and configured for connection to the air discharge tubes and configured for receiving thereon a NATO standard military canteen cap.

10. A kit for a transportable forced air dryer for articles of apparel comprising:

(a) a blower housing with an electrically operated blower therein and a blower plenum with a power cord attached to the plenum with a first air distribution manifold non-releasably attached to one side of the plenum, the first manifold including a pair of spaced generally parallel tubes, each with a plurality of spaced air discharge tubes and form expander for an article to be dried disposed with each discharge tube in spaced in generally parallel relationship thereto and an end support member non-releasably attached to the pair of tubes distal the plenum;

(b) a second air distribution manifold with a pair of spaced generally parallel tubes attached to a mounting plate configured for quick-connect and disconnect to a side of the plenum opposite the first manifold, the second manifold including a plurality of spaced air discharge tubes disposed on the pair of parallel tubes and an article form expander for an article to be dried disposed in spaced generally parallel relationship thereto from each air discharge tube and an end support member configured for connect and disconnect on the second manifold;

(c) wherein the second manifold is nested inverted on the first manifold with the respective discharge tubes and article support form closely interdigitated; and

,

(d) a container having the blower housing with plenum and nested manifolds, power cord and second support plate received therein, the container sized for closely inter-fitting over the nested components for hand carrying the dryer to a remote site for assembly and operation.

11. The kit of claim 10, wherein the container comprises a tote bag.

12. The kit of claim 10, further comprising a plurality of nipples for connection to the air discharge tubes and configured for receiving thereon a NATO standard military canteen cap.

13. The kit of claim 10, further comprising a plurality of lengths of flexible tubing sized to interfit the ends of the air discharge tubes.
