Description

[0024] The invention will be described in more detail below by means of schematic figures of specific embodiments.

[0025] FIGS. 1A to 2C show different partial views and partial and partial sectional views of a weighted comforter according to the invention at hand.

[0026] FIG. 3 represents a further embodiment of a weighted comforter comprising a hexagonal structure.

[0027] In the drawing as well as in the description, identical or similar reference numerals will be used below in order to refer to identical or similar components or elements.

[0028] FIGS. 1A to 1C in each case show a top view onto one of the three main parts of the weighted comforter 2 according to the invention, an upper cover or upper outer layer 42, a lower cover or lower outer layer 42, as well as a core layer 10 comprising weight elements or weights 4, respectively. The weighted comforter, i.e. the core layer 10, the outer layers 42 and optional the cover 50 can have a width 14 of for example 135 cm and a length 12 of 200 cm.

[0029] FIG. 1A shows an upper outer layer 42 in a top view. The outer layer is divided into longitudinal channels comprising a width by means of seams. Provision can be made in the middle of the outer layer 42 for a zipper 52, by means of which the blanket or the outer layer 42, respectively, can be divided into two parts in a longitudinal direction. The outer layer can be provided with a circumferential hook and loop fastener, so as to connect the outer layer(s) 42 to a core layer 10. On the edge, outer layers and core layer are sewn with a piping.

[0030] The outer layer is provided with longitudinal channels 40, which run in the longitudinal direction across the outer layer 42. A width of the longitudinal channels can be adapted to width dimensions of weight and ventilation channels of the core layer 10.

[0031] FIG. 1B shows a core layer 10 of the weighted comforter comprising air channels 6 and weight channels 8, which run parallel to the length 12 of the blanket. The channels are in each case formed of two cotton layers 18, 20 with a length 36 of 20 cm. The weight channels have a width 32 of 8.5 cm and the air channels have a width 34 of 1.5 cm. The weight channels are divided into individual weight pockets 22 by means of stitched seams.

[0032] FIG. 1C corresponds exactly to FIG. 1A and will thus not be described once again.

[0033] FIG. 2A shows a sectional view through the weighted comforter in the longitudinal direction of a weight channel. The weighted comforter 2 comprises three layers, the outer layers 42 and the core layer 10, which, in turn, are in each case divided into three sublayers. The weighted comforter 2 furthermore also comprises a cover 50 of lycocell 30, which wraps the entire weighted comforter. The outer layers 42 in each case comprise two layers of a non-woven material or of a fleece material 28, respectively, which are connected to one another and which are filled with a cellulose filling material 26 in the embodiment at hand. The core layer 10, in the case of which an upper cotton layer 18 and a lower cotton layer 20 enclose weights 4 in the form of the filling material of glass beads, polypropylene or polyethylene 24, e.g. in particle form or in a particulate form, respectively, is arranged between the outer layers 42. The weight channel 8 extends along the entire longitudinal direction of the weighted comforter 2 and can be divided into individual weight pockets 22 by means of separating walls or stitched seams 38. The weight pockets 22 prevent that the weights 4 or also the polypropylene, polyethylene or the glass beads filling 24 can shift too much in the longitudinal direction. The weight pocket 22 has a length of 20 cm.

[0034] Analogous to FIG. 2A, FIG. 2B shows a sectional view through the weighted comforter in the transverse direction of the blanket through two weight channels 8 and two air or ventilation channels 6. The layer structure of the outer layers 42 corresponds to that of FIG. 2A. The weight channels 8 are cut in the transverse direction and thus have a smaller width 32 of 8.5 cm than in the longitudinal direction. In the shown section, two weight pockets 22 are illustrated, which are separated by an air channel 6. Here, the air channels 6 correspond to the weight channels, but only have a width 34 of 1.5 cm and are not filled. The air channels can be divided into air pockets in the transverse direction by means of stitched seams. It is preferred, however, that the air channels 6 extend along the entire length 12 of the weighted comforter 2. It can be seen in the cross section that the outer layers 42 are also divided in the transverse direction by means of stitching or stitched seams. Longitudinal channels 40 are formed in the outer layer 42 by means of the stitching. Here, the weighted comforter is set up in such a way that the sum of the width 32 (8.5 cm) of a weight channel 8 and of the width 34 (1.5 cm) of an air channel 6 of the core layer 10 corresponds to the width of a longitudinal channel 40 (10 cm) of the outer layers 42. It can thus be attained that the structure of the outer layers 42 corresponds to the structure of the core layer 10. In the illustrated embodiment, the core layer and the outer layers are in each case three-layered, and the weighted comforter is additionally surrounded by two lycocell 30 layers of the cover 50. This embodiment thus has 9 layers. The lycocell layer is connected to the fleece and non-woven as outer layer.

[0035] The weight channels 8 and air channels 6 are sewn adjacent to one another by the connection of the upper cotton layer 18 and lower cotton layer 20. The air channels 6 ensure an air circulation in the entire weighted comforter 2 at least in the core layer 10, while they exert pressure on the weight channels, whereby the filling weights 4 of glass beads, polypropylene or polyethylene particles remain distributed evenly and the movement of the filling material 24 is prevented at the same time. The blanket includes 14 air channels 6, which move through the entire length 12 of the blanket 2 or the core layer 10, respectively, and 14 weight channels 8, which are divided by horizontal seams in the width, whereby a total of up to 140 weight pockets 22 are formed.

[0036] Each weight channel 8 or each weight pocket 22, respectively, is filled with the filling material glass beads, polypropylene or polyethylene 24. Depending on the weight category ranges between 35 to 128 grams, in particular 43 grams of polypropylene, polyethylene or glass-beads filling 24 are located in each weight pocket 22. The used glass-beads filling 24 in the form of glass sand or the used polypropylene or polyethylene filling 24 in the form of balls can also be washed at 95 degrees (Celsius) and adapts well to the textiles due to the round shape of the individual weight elements 4.

[0037] The two outer layers 42 in each case comprise a non-woven fabric 28, a cellulose filling material 26, as well as a lycocell 30 cover 50. They are also stitched in longitudinal channels 40 and in each case blanket a width of a weight channel 8 and air channel 6 at a width of 10 cm per longitudinal channel 40 (mentioned in FIG. 2C). By means of this interaction of the widths of the channels in the core layer and the outer layers, the function of a comforter is reflected to the outside, and the appearance of the filling material can no longer be recognized from the outside.

[0038] As shown in FIG. 2C, this structure also provides for an improved mobility, which is associated with the intricacy of design of the connection of the weights and air channels. The blanket can be folded and washed, and the zipper in the center provides for an easier handling of blanket parts, which in each case weigh only half of the core layer. The separation through the zipper also allows to combine two different weight categories within one comforter to adjust for the different body weights if two people use the comforter, guaranteeing the optimization of pressure effects as stated in the medical literature which attributes 10% body weight to be effective

[0039] FIG. 3 represents a top view onto a weighted comforter 2, in the case of which the weight channels form a grid 46 of weight channels. Perpendicular air channels 44, which allow for an air exchange through the blanket, are formed in the spaces between the grid, The grid 46 of weight channels is divided by means of stitched seams 38 for dividing the weight channel into individual weight pockets, in order to prevent a movement of the weight filling inside the blanket. It can also be ensured by means of the stitched seams that the blanket can adapt well to a person, who lies underneath it. It goes without saying that triangular grids or square grids are also possible instead of hexagonal grids.

[0040] The inner core of the comforter may be manufactured by providing two fabrics on top of each other and applying seams in a longitudinal direction to form channels. Air channels may be filled with means for providing air flow, weight channels may be filled with filling material after sewing the seams.

[0041] Alternatively single channels may be pre-sewn and a plurality of these separate channels are laterally arranged and sewn together, thus forming the inner core of the comforter reaching to its extent. Advantageously, means for providing air flow and filling material may be inserted into the channels either before or after sewing the channels together, thus providing the option of facilitating the manufacturing process.

[0042] The air channels, which are provided e.g. in a aforementioned manner, may be supported by inserted tubes, preferably made of a soft material, to prevent collapse of the volume in an air channel and/or to prevent closing/sealing of the air channel by orthogonal stitch seaming. Alternatively a meshed tubes may be used, which further allows radial flow/entry of air into the tube. Further alternatively air-permeable tubes may be used for the same purpose.
