SLEEPING BAG TEMPERATURE RANGE EXTENDER INSERT

摘要

An insulated sleeping bag insert constructed such that when used with a sleeping bag provides additional insulation thickness above and to the sides of the user, thereby extending the lower limit of the usable temperature range of the sleeping bag. The insert is fitted with attachment mechanisms that allow it to be attached and retained in position within the interior of the sleeping bag. The insulated sleeping bag insert construction is unique in that, in addition to a layer of uniform insulation over the sleeper's body, additional insulation-containing space fillers are incorporated into the sides of the insert to fill-in around the sleeper for reducing the internal volume of the bag.

主权项

1. A sleeping bag assembly comprising:
a sleeping bag having a first half, a second half, a closure device for defining a primary sleeping compartment between the first and second halves when located in a closed position, and a pair of first insert attachment devices located along opposite lateral sides of the sleeping compartment; an insulated insert configured to be located within the primary sleeping compartment adjacent to the first half of the sleeping bag, the insulated insert having a pair of second insert attachment devices adapted to engage the pair of first insert attachment devices for releaseably securing the insulated insert to the sleeping bag for defining a secondary sleeping compartment configured to receive a user's body between the insulated insert and the second half of the sleeping bag; and at least one space filler extending lengthwise along an edge of the insulated insert and expanding inwardly into the secondary sleeping compartment for filling voids surrounding the user's body when received within the secondary sleeping compartment.
