Description

[0001] DESCRIPTION

[0002] BED COVER WITH OPENINGS

[0003] Field of invention

[0004] The present invention relates to a textile product for covering beds, more specifically to a textile product placed on a bed, namely a duvet cover, which has one or two openings for the passage of feet and its placement on the outside of the bed.

[0005] Context of the Invention

[0006] The term "Hot Sleeper" refers to a condition that affects people who constantly feel hot in bed and have difficulty cooling down at night. This can be incredibly frustrating and lead to an uncomfortable, poor-quality night's sleep.

[0007] According to neurologists and sleep study specialists, the sleep-wake cycle, called the circadian rhythm, is linked to the body temperature regulation system.

[0008] For sleep to begin, it is essential that the body lose heat, and a drop in internal temperature is mandatory. This drop begins approximately two hours before we fall asleep and lasts until morning. As internal temperature drops, to promote sleep, skin temperature rises, which causes the sensation of heat during the night.

[0009] The feet function as powerful thermoregulators of the body, authentic radiators and heat evaporators, not only because they have a large surface area, but also because they have specialized blood vessels (vasodilators) that dilate, which facilitates the passage of a greater quantity of blood volume and, therefore, releases heat quickly when necessary.

[0010] For this reason, that is, due to the need to cool the body in order to sleep, and because the feet are a good way to help the body cool down, sleep experts advise that, in certain circumstances, especially in people who suffer from the "Hot Sloppier" condition, leaving the feet uncovered at night can help you sleep better.

[0011] Background of the Invention

[0012] Several solutions have been developed to allow feet to cool down.

[0013] One of the solutions presented are the "Bedsheet lifting bars" https: / / www.amazon.com / Adj ustable-Blankets-Hospital-Accessories-Arthritis / dp / B07KSSYlNX?ref=ast sto dp. Another existing solution are the "Bedsheet lifting blocks" https: / / bedblock.co / , or even the "Fresh sheets" https: / / www.amazon.com / HUSH-Iced-Sheet-Pillowcase-White / dp / B09MR8D434 / ref=sr11sspa?Keywords=best%2Bcoolinq%2Bsheets&qid=1701365613&sr=8-l-spons&sp csd=d21kZ2V0TmFtZTl zcF9hdGY&th=l.

[0014] Other existing solutions refer to bed coverings, namely duvets, bedspreads, blankets or blankets, in which openings are made that allow the feet located under these coverings to be removed.

[0015] An example of one such solution is shown in US 2014 / 0317846, which refers to a "Multi-panel bed canopy". Although it does not specifically mention the problem that the present invention solves, US 6,640,362 refers to one of the potential solutions, which is the placement of openings in the canopy.

[0016] Other documents address solutions to more specific problems, namely when, in a double bed, one member of the couple suffers from the condition mentioned above and the other does not.

[0017] However , no document was found in the state of the art that referred to or encouraged the solution as presented in this document .

[0018] Advantages of the invention

[0019] The invention described in this document has the great advantage of providing a fresh sleep without losing the comfort and coziness of a made bed, as it is no longer necessary to undo the bed to be able to put a foot outside.

[0020] It also has the advantage of working for couples who share the bed, but not the temperature, meaning only one person in the couple can use the opening, without the other person being disturbed.

[0021] It also has the advantage of having a way of attaching the filling unit to the duvet cover, so that both work as a single piece and thus make it easier to use.

[0022] Brief description of the figures

[0023] These and other features can be readily understood from the accompanying drawings, which should be considered as mere examples and in no way restrictive of the scope of the invention. In the drawings, and for illustrative purposes, the measurements of some of the components may be exaggerated and not drawn to scale. The absolute dimensions and relative dimensions do not correspond to the actual relationships for carrying out the invention.

[0024] In one embodiment:

[0049] Detailed Description of the Invention By "substantially" it is meant that the description of the shape or position of an element of the present invention is not mathematically or geometrically exact, but that the shape or position of an element of the present invention is recognized by one skilled in the art as having generally or approximately the shape or position described.

[0050] By "duvet cover" or simply "cover" we mean the protective cover for duvets, which is made up of two layers joined together at the sides and at the head, leaving the foot part open to introduce the filling or an extra insulating layer.

[0051] As will be clear to one skilled in the art, the application of the principles described herein is not limited to the embodiments shown. Possible changes that may occur in the present invention, defined in number, remain within the scope of the present invention.

[0052] The application of the principles described herein is not limited to the specific embodiments presented.

[0053] The principles described here can be used with any bed covering system.

[0054] In a preferred embodiment, the fastening elements are buttons. In other embodiments, the fastening elements are, in particular, but not exclusively, clasps, zippers, clips, Velcro, pins, magnets or cords.

[0055] Bed coverings according to the principles described herein may comprise any number of the features presented. Additionally, although some embodiments present multiple novel features, and as will be observed throughout this document, all features may be independent and it is not essential that all be used in a single embodiment.

[0056] Referring to the figures, the invention relates to a duvet cover (1) for a bed having at least one opening (2) that allows the feet to be placed outside to promote heat release. This opening (2) is hidden by a flap (3) and is located in the bottom area of ​​the duvet cover (1), next to the feet, at a distance of between 15% and 25% from the bottom of the bed. This location facilitates use when one wants to place at least one of the feet outside, requiring only a slight lifting and bending of the legs and sliding at least one foot out of the duvet cover (1).

[0057] The duvet cover (1) has one or two openings (2).

[0058] If the duvet cover (1) is for a single bed, the duvet cover (1) has an opening (2) , placed in a substantially central position in relation to the width of the duvet cover (1) .

[0059] In one embodiment, where the duvet cover (1) is for a double bed, the duvet cover (1) has one or two openings (2). In one embodiment, where only one member of the couple suffers from the "Hot Sleeper" condition, the duvet cover (1) will have a specific opening (2) on the right or left side, depending on which side that member of the couple sleeps on. In another embodiment, where only one member of the couple suffers from the "Hot Sleeper" condition, the opening (2) is placed on one of the sides of the duvet cover (1), either left or right, and the correct placement will be achieved by aligning the position when placing the cover on the bed. In yet another embodiment, where both members of the couple suffer from the "Hot Sleeper" condition, the duvet cover (1) will have two openings (2), one on the side of each member of the couple.The openings (2) are placed in a substantially central position in relation to the width of half the duvet cover (1).

[0060] The opening (2) is hidden under a flap (3) placed across the entire width of the duvet cover (1). In the case of the duvet cover (1) for a double bed with only one opening, the fabric flap (3) is applied to both the top layer (1.3) and the bottom layer (1.4) of the cover, thus making it possible to use it reversibly. This way, the opening (2) can be used by both people sleeping on the left and right sides of the double bed.

[0061] In the event that both people wish to put their feet out, that is, in cases where there are two independent openings (2), the fabric flap (3), since it runs the entire width of the bed, covers both openings (2).

[0062] In the case where a filling unit (4) is inserted into the duvet cover (1), it is also necessary that the filling unit (4) has openings (2) located substantially coincidentally with the openings (2) in the duvet cover (1). Thus, the filling unit (4) inside may have an opening (2) located on one side or on both sides depending on the duvet cover (1). The filling unit (4) inside may also have openings (2) on both sides and be used in a duvet cover (1) with only one opening (2). In these cases, the opening (2) of the unused filling unit (4) will be closed. The fastening elements (5.1, 5.2) , in order to ensure that the openings (2) of the duvet cover (1) and the filling unit (4) remain substantially coincident, even with the movement of people during sleep, the filling unit (4) , at the edges of the opening (2) , or in a location close to the end of the opening (2) , has blockers (5.3) that allow the placement of fastening elements (5.1, 5.2) . In the upper layer (1.3) of the duvet cover (1) , at the edge of the opening (2) on the side of the feet (1.2) , a fastening element is placed that faces inwards, while in the lower layer (1.4) of the cover, at the edge of the opening (2) on the same side of the feet (1.2) , a blocker is placed that also faces inwards. In this way, the upper fixing element (5.1) placed in the upper layer (1.3) of the cover is inserted into the blocker (5.3) on the filling unit (4) and in the lower layer (1.4) of the cover and remains hidden.

[0063] Conversely, in the upper layer (1.3) of the duvet cover (1), at the edge of the opening (2) on the head side (1.1), a blocker (5.3) is placed which faces inwards, while in the lower layer (1.4) of the cover, at the edge (or end) of the opening (2) on the same side as the head (1.1), a lower fixing element (5.2) is placed which faces inwards. In this way, the lower fixing element (5.2) placed in the lower layer (1.4) of the cover is inserted into the blocker (5.3) on the filling unit (4) and in the upper layer (1.3) of the cover and is hidden.

[0064] In order for the duvet cover (1) to be washed or ironed or spread out to air dry, the upper fastening element (5.1) located on the upper layer (1.3) on the foot side (1.2) , is inserted into the blocker (5.3) located on the upper layer (1.3) on the head side (1.1) , while the lower fastening element (5.2) located on the lower layer (1.4) on the head side (1.1) , is inserted into the blocker (5.3) located on the lower layer (1.4) on the foot side (1.2) .

[0065] This ensures that the openings (2) of the duvet cover (1) remain closed and facilitate use in the domestic scenarios mentioned above, as the duvet cover (1) will maintain its rectangular structure.

[0066] Forms of realization

[0067] In a preferred embodiment, as shown in figures 6a, 7a, 8a, 9a, 10a and 11a, the fastening elements (5) are buttons, the upper fastening element (5.1) is an upper button, the lower fastening element (5.2) is a lower button and the blocker (5.3) is a buttonhole.

[0068] In an alternative embodiment, as shown in figures 6b, 7b, 8dB 9b, 10b and 11b, the fastening elements (5) are spring buttons, the upper fastening element (5.1) is an upper male spring button, the lower fastening element (5.2) is a lower male spring button and the blocker (5.3) is a female spring button.
