Problems solved by technology

Such conventional air mattresses, represented in the prior art as far back as U.S. Pat. No. 31048 to Williams, Jan. 1, 1861 to as recently as U.S. Pat. No. 5787531 to Pepe, Aug. 4, 1998 have a problem in that the camper fails to get sound sleep because the sleeping bag is prone to slipping off the mattress.
Large conventional air mattresses are also difficult to inflate.
If a small or thin mattress is used then the problem of slipping off becomes more apparent and the unit is not likely to separate the user sufficiently from a cold surface to provide good insulation.
These devices, while inventive, are undesirable because of their large size, the large volume of air needed to fill them, or their susceptibility to puncture.
These again are more susceptible to puncture and require a large volume of air to fill.
While achieving the goals of stability on the mattress and greater comfort, they again introduce complexity and additional pieces of equipment that have to be kept track of and transported.
This device is not inflatable, generally not portable for backpacking, adds bulk and weight to the camping gear, uses many sheets to form a coverlet, and is not designed to receive a sleeping bag.
These devices work as proposed but none have been adapted to camping purposes.
Many in the prior art are complicated, difficult to manufacture, and too fragile for outdoor use.

second embodiment

[0049] FIG. 10 is an embodiment where the interior of mattress portion 20 is comprised of a self-inflating bladder 50a. The interior of self-inflating bladder 50a is comprised of expandable foam 51a. Expandable foam 51a is surrounded by a gas-impermeable shell 52a. Gas impermeable shell 52a is partially cut-away in this view for the purpose of revealing expandable foam 51a. Sealed to gas-impermeable shell 52a of self-inflating bladder 50a is air-fill mechanism 40. Air-fill mechanism 40 is constructed and connected to the second embodiment in a similar manner as in the preferred embodiment.

Operation of the Second Embodiment

[0050] The second embodiment is operated in the same manner as the preferred embodiment except for the air-fill mechanism 40. In the second embodiment, valve 46 is opened and air begins flowing into self-inflating bladder 50a because of the expansion of expandable foam 51a. When the sleeping device is rolled up, expandable foam 51a is compressed, and air is forced ...

third embodiment

Description of a Third Embodiment

[0051] FIG. 11 depicts an embodiment where the interior of mattress 20 is comprised of cushioning foam 50b.

Operation of the Third Embodiment

[0052] The third embodiment is operated in the same manner as the preceding embodiments except that it is not inflatable and thus requires no air-fill mechanism.

fourth embodiment

Description and Operation of a Fourth Embodiment

[0053] FIG. 12 depicts an embodiment where the coverlet portion is a netting coverlet 22a constructed of a netting material and fastened to mattress 20 by snaps 30a. Netting coverlet 22a performs the same function as coverlet 22.

Abstract

An inflatable mattress is provided that has a method of retaining a sleeping bag on top of it. Retaining a sleeping bag on top is achieved by using a coverlet. The coverlet is connected to the top of the inflatable mattress by suitable fasteners. The pocket formed between the coverlet and mattress portion is where a sleeping bag is inserted. An air fill mechanism is provided that is easily accessible from the outside of the mattress. An integral protective flap is also provided. The flap encases the mattress when in a rolled-up configuration and protects it during storage and transport. The device operates as one self-contained unit.

Description

CROSS REFERENCE / RELATED APPLICATION[0001] This invention is related and complimentary to the invention of our co-pending application Ser. No. 09 / 793270, filed Feb. 22, 2001.[0002] 1. Field of the Invention[0003] The present invention relates to a mattress and more particularly to a mattress that is used for outdoor activities such as camping, hiking, backpacking, military purposes, and the like.[0004] 2. Description of the Prior Art[0005] Those who enjoy the outdoors and wilderness activities have always sought to bring some form of comfort along on their adventures and thus the conventional inflatable camping accessory has an extensive history in the prior art. Inflatable devices are desirable because when deflated they are light, compact, and easy to transport. The conventional air mattress for camping purposes is composed of an inflatable device that lies on the ground and onto which a sleeping bag is laid. Such conventional air mattresses, represented in the prior art as far bac...
