Abstract
A sleeping bag (10) includes baffles (20) cut according to a curved pattern in order to enhance the loft of the canopy of the sleeping bag, thereby improving the thermal performance of the sleeping bag.
Description
- This invention relates to sleeping bags, and particularly to sleeping bags which utilise down and/or feathers and/or other bulk material for insulation.
- It is well known to include baffles extending between the inner skin of the bag and the outer skin of the bag for the purpose of preventing unwanted migration of the insulating material. The present invention provides a novel baffle construction which improves the loft and thermal performance of the sleeping bag.
- The present invention provides a sleeping bag including baffles according to the following claims. Preferred features of the invention will be apparent from the dependant claims and from the following description of the preferred embodiment.
- The invention will now be described in a non-limiting manner with respect to preferred embodiments in which:
-
FIG. 1 is perspective view of a sleeping bag; -
FIG. 2 is a sectioned view along line 2-2 ofFIG. 1 ; -
FIG. 3 is a sectioned view along line 3-3 ofFIG. 1 ; -
FIG. 4 is a view of a pair of prior art baffles for the canopy and floor respectively; -
FIG. 5 is a view of a first embodiment of a pair of baffles for the canopy and floor respectively according to the present invention; -
FIG. 6 is a view of a second embodiment of a pair of baffles for the canopy and floor respectively according to the present invention; -
FIG. 7 is a view of a third embodiment of a pair of baffles for the canopy and floor respectively according to the present invention; -
FIG. 8 is a view of a fourth embodiment of a pair of baffles for the canopy and floor respectively according to the present invention; and -
FIG. 9 is a view of a fifth embodiment of a pair of baffles for the canopy and floor respectively according to the present invention. - With reference firstly to
FIG. 1 , there is illustrated a downsleeping bag 10. Thesleeping bag 10 has a longitudinal axis A-A and is formed in the usual manner from anouter skin 12 and aninner skin 14. Thesleeping bag 10 has a lateral zipper 16 provided to facilitate entry to, and exit from, thesleeping bag 10. - Referring now to
FIG. 2 , there is shown a sectional view taken along line 2-2 ofFIG. 1 . In the sectional view shown inFIG. 2 , it would readily seen that the sleeping bag combines an upper canopy portion 11, which in use is above the user, and alower floor portion 13, which in use is below the user. Down 15 is provided intermediateinner skin 14 andouter skin 12 in the usual manner. Aflap 18 is provided on the upper canopy portion 11 in order to limit the loss of body heat through the non-insulated area at and adjacent to zipper 16. - Turning now to
FIG. 3 , there is shown a sectional view taken along line 3-3 ofFIG. 1 . It will be appreciated that line 3-3 is coincident with a transverse baffle provided in the sleeping bag. It will be noted that there is anupper baffle 20 provided in the canopy portion of the sleeping bag and alower baffle 22 provided in thefloor portion 13 of the sleeping bag. Theupper baffle 20 is stitched to thelower baffle 22 at the left hand side as shown inFIG. 3 . - In the prior art, the
upper baffle 20 andlower baffle 22 were both cut according to a straight pattern. An example of the prior art straight cut baffles is shown inFIG. 4 . Typically these baffles are formed from a mesh material. It should be noted at this stage that, whilst the straight baffles of the prior art are cut according to a straight pattern as shown inFIG. 4 , they nonetheless adopt a deformed or curved shape when actually in place within the sleeping bag. Hence, a distinction is drawn between the baffles being curved when in situ, and baffles which are curved from the outset when cut according to a curved pattern. - With reference now to
FIG. 5 toFIG. 9 , there are shown multiple embodiments of baffles cut in a curved manner according to the present invention. In each ofFIGS. 5 to 9 thelower baffle 22 is straight cut as per the lower baffle of the prior art. However, in alternative embodiments (not illustrated), thelower baffle 22 could also be cut according to a curved pattern. - With reference firstly to
FIG. 5 , there is shown thebaffle 20 which is cut according to a radial arc. - With reference to
FIG. 6 , theupper baffle 20 is cut according to a radial arc and the width of the baffle varies along its length with the point of maximum width midway along the length ofupper baffle 20. - With reference to
FIG. 7 , there is shown anupper baffle 20 having a consistent width, but being of substantially U-shaped configuration. - With reference to
FIG. 8 , there is shown another U-shapedupper baffle 20, although in this case the upper baffle varies in width along its length. - Finally, with reference to
FIG. 9 , theupper baffle 20 is cut according to several straight segments, with each straight segment being angularly off set with respect to a neighbouring straight segment. - As mentioned above, both the upper and lower baffles are typically formed from a mesh-like material which has limited structural strength. Notwithstanding this limited structural strength, it has been surprisingly found that upper baffles formed according to the present invention result in the canopy portion of the sleeping bag having additional loft and hence additional thermal performance.
- Whilst the invention has been described with reference to specific examples, it will of course be appreciated that many different configurations on baffle will fall within the scope of the present invention.
Claims (7)
1. A sleeping bag having a longitudinal axis, an upper canopy portion, and a lower floor portion, the sleeping bag comprising an inner skin and an outer skin, insulating material being located intermediate the inner and outer skins of at least the canopy portion, transverse baffles extending between the inner and outer skins of the canopy portion for inhibiting migration of the insulating material in the canopy portion, characterised in that the transverse baffles are cut from fabric according to a curved pattern.
2. A sleeping bag as claimed in claim 1 , wherein the curved pattern is a radial arc.
3. A sleeping bag as claimed in claim 2 , wherein the width of the curved pattern varies along its length.
4. A sleeping bag as claimed in claim 1 , wherein the curved pattern is substantially U-shaped.
5. A sleeping bag as claimed in claim 4 , wherein the width of the curved pattern varies along its length.
6. A sleeping bag as claimed in claim 1 , wherein the curved pattern includes multiple straight sections, with each section being angularly offset with respect to a neighbouring straight section.
7. A sleeping bag as claimed in any one of claims 2 to 6 , wherein the sleeping bag includes transverse baffles in the floor portion, and where the transverse baffles in the floor portion are shorter than the corresponding baffles in the canopy portion.
