The system, apparatuses and methods described herein generally relate to a head support system and, in particular, to portable head support for sleeping when traveling.
For centuries travelers have been seeking devices to help sleep when traveling. Long distance travel requires long times sitting and waiting to arrive at the destination. This is a particularly acute issue when traveling on red-eye, overnight airplane flights.
Various designs for portable pillows have been proposed. Some have designed Orthopedic pillows correct body positioning for sleepers. The pillow sets the placement and orientation of particular body parts in safe and healthy resting positions. There are particular challenges for body positioning when a sleeper is in the sitting position, such as when a passenger is seated on an airplane flight. The room is limited, and mobility is restricted. An ideal body position for sleeping is not always possible in an airplane seat. Difficult seated positions for sleeping can also be found in other situations, such as riding in trains and long distance rides in cars.
A number of devices have been developed to facilitate sleeping in the seated position. A neck pillow is a common option for travelers. The U-shaped pillow is placed on the back of the neck of the user so that the head is prevented from falling side to side and back and forward. The neck pillow fits on the user so that the height is always correct and set by the neck of the user. But the neck pillow is bulky, not particularly portable and difficult to store.
Several patents and publications are available for review in the field of sleeping devices, when the body is in the seated position. U.S. Patent Publication No. 20130047342, published for Schwingendorf et al, on Feb. 28, 2013, discloses a neck pillow with a bone structure support. U.S. Patent Publication No. 20130125312, published for Harooni, on May 23, 2013, describes a new pillow with a hood. The hood suspends the pillow around the neck to accommodate a sleeper. U.S. Design Pat. No. D695,996, issued on Dec. 24, 2013 to Paul, shows a travel pillow with a scarf attachment to maintain position of the neck pillow on the user.
The prior art devices fail to stabilize the head of the sleeper on the seat. The devices do not consistently hold the position of the head to the seat back or top of the seat. Additionally, the devices are not adjustable for sleepers of different sizes and heights. Furthermore, the devices are not portable. There is a long felt need in the industry for a comfortable head support that can be easily placed in a laptop bag for transport.
An apparatus for supporting a head of a user is described herein. The apparatus is made up of a first piece of fabric and a second piece of fabric with a plurality of flat, rigid geometric shapes arranged in between the first and second fabric. There is adhesive connecting the first fabric and the second fabric at the edges of the fabric and in between the geometric shapes, such that the fabric holds the geometric shapes in place. In addition, there are a plurality of patches of hook and loop material adhered to the fabric. The arrangement of the geometric shapes is such that when the fabric is folded the hook and loop material hold the geometric shapes into a hollow three dimensional structure rigid structure.
In some embodiments of the apparatus there are eight geometric pieces. In some cases the adhesive could be heat welds or chemical adhesive or thread sewn between the first and second fabric. In some embodiments the fabric is brushed polyester and in other embodiments it is felt. The geometric shapes could be hard plastic, cardboard or other materials.
A method of creating a support for a head of a user is also described. The method comprises the steps of (1) folding a flat structure with a plurality of geometric shapes adhered between two pieces of fabric with a first fold such that a first geographic shape is behind the other geometric shapes; (2) folding the flat structure with a second and third folds, moving a second and third geometric shapes behind the flat structure, such that the second geometric shape is in contact with a fourth geometric shape; (3) folding the flat structure with a fourth fold such that the first geographic shape is in contact with a fifth geographic shape; (4) folding an eighth geographic shape is folded in front of the flat structure; and (5) folding a seventh and sixth geographic shape forward until the eighth geographic shape is in contact with the fifth geographic shape.
The first geographic shape could be a triangle. The second geographic shape could be a polygon. The third geographic shape could be a triangle. The fourth geographic shape could be a polygon. The fifth geographic shape could be a polygon. The fifth geographic shape could be divided into two sections. The sixth geographic shape could be a triangle. The method could further comprise the step of adhering the fifth geographic shape to the eighth geographic shape with a hook and loop mechanism. The method could further comprise the step of adhering the fifth geographic shape to the first geographic shape with a hook and loop mechanism. The method could further comprise the step of placing the third geometric structure on a shoulder of a user and resting a head against the seventh geometric shape.
The present inventions describe a foldable neck rest 100 for supporting the head of a traveler, whether the traveler is attempting to sleep in an airplane, train, boat, or automobile. The neck rest 100 is stored flat or folded twice for transport, and then folded into shape when the user desires sleep. The neck rest is made of rigid material with a number of flexible areas for folding. The neck rest also has several fasteners for holding the folded pieces together.
All of the sections are enclosed in between two pieces of a fabric material 101 such as felt, brushed polyester, cotton, nylon, viscose, polyester nylon blend, rayon, wool, terrycloth, or similar materials. In another embodiment, the sections could be enclosed in single piece of fabric folded in half. The two pieces of fabric material 101 could be connected by sewing, staples, adhesive, heat welding, sonic welding, or similar techniques. The fabric material extends beyond the geometric shapes by approximately 0.5 cm in each direction. The extended fabric is used for adhering the two pieces of fabric together. The thickness of the fabric and rigid material can vary, but in one embodiment is approximately 0.4 cm. In another embodiment, the fabric material is created around the geometric shapes using a thermoform process that creates a 3-D shape and structure. In still a further embodiment, a 3-D printer with multiple heads is used to create the geometric shapes of a ridged material inside of a more flexible material.
The neck rest 100 is 11 cm by 52.5 cm in size in one embodiment, but the dimensions can be proportionally changed without detracting from the inventions described herein. It is envisioned that there will be different sizes for different people.
The neck rest 100, at one side, has a scalene triangle shape 101 of rigid material. This scalene triangle 101 has an angle of 79 degrees at the outer corner, 77 degree at the inner corner, and 24 degrees at the far end. Given the tolerances, this triangle could be an isosceles triangle in some embodiments. The width of the triangle is approximately 9 cm and the length is about 3.75 cm.
The scalene triangle 101 has a triangular patch 102 of hook material from a hook and loop material (for instance Velcro). This triangular patch 102 is a right triangle 2 cm along the bottom and 4.5 cm wide. It is located at the top of the scalene triangle 101. In one embodiment, it is adhered to the fabric with an adhesive, There are two triangular patches 102 of hook material, one on each side of the neck rest 100 in approximately the same location.
Next to the scalene triangle 101 trapezoidal shape 103 of rigid material. The first trapezoid 103 has a short length of 6 cm and a long length of 14.5 cm. The angles are 103 degrees along the short length by the scalene triangle 101 and 124 degrees at the other side. The long length has a 77 degree angle by the scalene triangle 101 and a 56 degree angle on the opposite end. The width of the first trapezoid is about 10 cm.
The first trapezoid 103 has a 5 cm by 1 cm patch 104 of hook material from a hook and loop material (for instance Velcro) along the top edge of the fabric starting at the corner along the long edge of the first trapezoid 103 near the peak of the scalene triangle 101. There are two patches 104 on the neck rest 100, one on each side of the first trapezoid 103. In one embodiment, when the neck rest 100 is laid flat, the patch 104 is close to, but does not meet, the triangle patch 102. When folded, the two patches 102,104 may be in contact.
Adjacent to the first trapezoid 103 is an isosceles triangle 105 of rigid material with two 56 degree angles on the bottom and a 68 degree angle on the top. Given the tolerances, this could be an equilateral triangle. The isosceles triangle 105 has a width of 9.5 cm and a base of 13 cm. In some embodiments, the isosceles triangle 105 is covered with a tactile material to increase friction of the triangle on a user's shoulder, so that the head rest 100 does not slip from position when in use.
Next to the isosceles triangle 105 is a second trapezoid 106 of rigid material. This second trapezoid 106 has a short base of about 3 cm and a long top of about 15 cm. The second trapezoid is about 10 cm wide. The short base has an angle of 124 degrees on the side by the isosceles triangle 105 and an angle of 121 degrees on the other side. The long top has an angle of 56 degrees on the side by the triangle 105 and 59 degrees on the other side.
The second trapezoid 106 has a 5 cm by 1 cm patch 107 of loop material from a hook and loop material (for instance Velcro) along the top edge of the fabric starting at the corner along the long edge of the second trapezoid 106 opposite the peak of the isosceles triangle 105. There are two patches 107 on the neck rest 100, one on each side of the second trapezoid 106.
Adjacent to the second trapezoid 106 is a third trapezoid 108 of rigid material. This trapezoid 108 has a long base, perhaps 11.5 cm and a shorter top 6 cm in length. The third trapezoid 108 is about 10 cm in width. This trapezoid has a 59 degree angle at the long base by the second trapezoid 106 and a 90 degree angle at the other side of the long base. The short top has a 121 degree angle at the side near the second trapezoid 108 and a 90 degree angle at the other corner. There is also a fold or break in the rigid material delineated by the dashed line 113. This break 113 does not have a seam in the fabric, and the fabric holds both portions of the rigid material closely together. The break occurs at the top corner of the trapezoid 108 and continues to the long base at 5.5 cm from the second trapezoid 106. This creates a 5.5 cm by 10 cm right triangle and a 6 cm by 10 cm rectangle within the area of the third trapezoid 108.
The third trapezoid 108 has a 6 cm by 4 cm right triangle patch 109 of loop material from a hook and loop material (for instance Velcro) along the top edge of the trapezoid 108 starting at the corner where the internal rectangle and triangle meet. There are two patches 109 on the neck rest 100, one on each side of the third trapezoid 108.
Next to the third trapezoid 108 is a right triangle 110 of rigid material. The right triangle 110 has a 6 cm top and a 10 cm width. The angle at the bottom is 29 degrees and at the top right the angle is 61 degrees.
Next to the right triangle 110 is a trapezium 111. The trapezium 111 has a base about 4 cm in length. On the side of the right triangle 110, the angle is 61 degrees at the base. At the opposite corner, the angle is 147 degrees. From that corner, the side runs 8.5 cm to a corner. This corner has a 73 degree angle to a top side, the top side has a length of about 7.5 cm to a 79 degree corner. The final side has an 11 cm side.
Adjacent to the trapezium 111 is a second right triangle 112. This second right triangle 112 has sides of 6 cm by 5 cm. The angle closest to the trapezium 111 is 33 degrees and the remote angle is 57 degrees.
The second right triangle 112 has a 4.5 cm by 4.5 cm right triangle patch of hook material from a hook and loop material (for instance Velcro) coveting most of the second right triangle 112. There are two patches on the neck rest 100, one on each side of the second right triangle 112.
The folding pattern described above is for the right side sleep support, if you turn the headrest over on the long side and follow folding instructions above, the neck rest loot shall accommodate the left side for sleep support.
When unfolded in its flat state, the neck rest 101 can be folded into a 26 cm by 16 cm by 1 cm thick shape for easy storage in a folio or a laptop bag. The isolates triangle 105 is moved backwards at the fold between the isolates triangle 105 and the second polygon 106 until the isolates triangle 105 flat against the second polygon 106. Next, the third polygon 108 is pushed backwards at the fold between the third polygon 108 and the second polygon 106 until the third polygon 108 flat against the isolates triangle 105.
The foregoing devices and operations, including their implementation, will be familiar to, and understood by, those having ordinary skill in the art. All sizes used in this description could be scaled up or down without impacting the scope of these inventions. All angles have a tolerance of ±10 degrees.
The above description of the embodiments, alternative embodiments, and specific examples, are given by way of illustration and should not be viewed as limiting. Further, many changes and modifications within the scope of the present embodiments may be made without departing from the spirit thereof, and the present invention includes such changes and modifications.
