DETAILED DESCRIPTION
[0036] To further illustrate the disclosure, embodiments detailing a travel pillow are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
[0037] FIG. 1 is a perspective view of a travel pillow 300 according to Example 1 of the disclosure. The travel pillow 300 is U-shaped and comprises a notch for receiving the neck and head of a user, thus providing a natural resting position for improving neck and upper back pain of the user.
[0038] As shown in FIG. 2, the travel pillow 300 comprises a mounting assembly 200 and a main body (not shown). The main body comprises a U-shaped case 100 detachably connected to the mounting assembly 200 to allow for easy assembly and disassembly of the travel pillow 300, thus allowing easy cleaning and replacement of the mounting assembly 200 and the main body. The term “detachably connected” refers to connection means that provide detachable connectors for joining different parts together and hence allow low-cost replacement of specific parts.
[0039] Referring to FIGS. 1-2, the mounting assembly 200 is U-shaped and comprises an inner surface in contact with the U-shaped case. The U-shaped case comprises an outer surface fitting in with the inner surface. The mounting assembly 200 is matched with the U-shaped case 100 in shape and it can be detachably attached thereto by any suitable connection means such as zippers, buttons, and clamps. The detachable connection means allow for easy assembly and disassembly of the travel pillow, allow cleaning and replacement of the main body or the U-shaped case 100.
[0040] As shown in FIGS. 3-4, the mounting assembly 200 comprises a cover 210, a U-shaped filler 220, and an inner frame 230. The cover 210, the U-shaped filler 220, and the inner frame 230 are disposed sequentially from outside to inside so as to protect the neck of the user. The U-shaped filler 220 is detachably attached to the U-shaped case 100. The cover 200 is configured to protect the U-shaped filler 220 and the inner frame 230 from being damaged. The cover 210 comprises an arc-shaped middle 210a and two end parts 210b. The cover 210 covers a plurality of connectors (not shown) disposed on the U-shaped filler 220 to give an improved visual aesthetic. The arc-shaped middle 210a is configured to protect the U-shaped filler 220 from being damaged. Each end part is configured to protect the corresponding arm from being damaged. The cover 210, the U-shaped filler 220, and the inner frame 230 are successively connected by the plurality of connectors, which allows for easy attachment and detachment of the cover 210 and the inner frame 230. The U-shaped filler 220 is configured to improve user's comfort. The inner frame 230 is configured to support the main body and the U-shaped filler 220, thus allowing for easy assembly of the travel pillow 300.
[0041] Referring to FIG. 8, the inner frame 230 comprises an arc-shaped support body 231 and two arms 232; the two arms 232 are rotatably disposed on both ends of the arc-shaped support body 231, respectively. An included angle between the arc-shaped support body 231 and each arm is adjusted to satisfy the requirement of the user. The arc-shaped support body 231 is configured to prop up the user's neck. The two arms 232 are rotated to transmit pressure from the arc-shaped support body 231 to the main body so as to adjust an opening of the main body for receiving the neck of the user, thus improving user's comfort.
[0042] Referring to FIG. 4, the cover 210 comprises an arc-shaped middle 210a and two end parts 210b; the two end parts 210b are formed integrally with the arc-shaped middle 210a or detachably connected thereto by a bolted joint or a snap-fit joint; a detachable connection allows for easy maintenance of the inner frame 230 and rapid replacement of the two arms 232 or the arc-shaped support body 231; an integral formation is performed through a stamping process, reducing number of components and greatly reducing manufacturing time. The cover 210 comprises a rigid-plastic material or a stiff metal material for protecting the U-shaped filler 220 and the arc-shaped support body 231 from being damaged.
[0043] Referring to FIGS. 5 and 6, the U-shaped filler 220 is detachably connected to the U-shaped case 100 through a zipper or a button; the zipper comprises nylon, resin, or metal; the zipper or the button is low cost, easy to manufacture, and allows for disassembly and replacement of the U-shaped filler 220 and the U-shaped case 100; the U-shaped filler 220 comprises an elastic material such as silicone or rubber, which is stiffer than a sponge or a cloth; the elastic material enables a stable bolt connection among the U-shaped filler 220, the cover 210, and the inner frame 230; as the two arms 232 rotates relative to the arc-shaped support body 231, the elastic material stretches and does not tear easily, compared to the cloth material; the silicone or rubber improves comfort and prop for a user's neck; and the U-shaped filler 220 is detachably connected to the U-shaped case 100, which allows easy cleaning or replacement of the U-shaped case 100.
[0044] As shown in FIG. 7, the U-shaped filler 220 comprises a first groove 221; as shown in FIGS. 9 and 10, the arc-shaped support body 231 comprises a first protrusion 231a; the first groove 221 is detachably connected to the first protrusion 231a to fix the U-shaped filler 220 on the arc-shaped support body 231, which allows for easy assembly and disassembly of the travel pillow 300.
[0045] As shown in FIG. 7, the U-shaped filler 220 further comprises a second groove 222; as shown in FIG. 11, each of the two arms 232 comprises a second protrusion 232a; the second groove 222 is detachably connected to the second protrusion 232a to fix the corresponding arm 232 on the U-shaped filler, which allows for easy assembly and disassembly of the travel pillow 300.
[0046] Referring to FIGS. 9, 12, and 13, the travel pillow 300 further comprises two rotary connectors each for controlling an included angle between the arc-shaped support body 231 and a corresponding arm 232; each end of the arc-shaped support body 231 comprises a first knuckle 231b; and the included angle is controlled to fit a diverse range of neck shapes, thus improving user's comfort.
[0047] As shown in FIGS. 12 and 13, each arm 232 comprises a second knuckle 232b; as shown in FIGS. 14 and 15, the first knuckle 231b comprises a through hole, and each rotary connector comprises a rotating shaft 233 and a nut 234; the rotating shaft 233 comprises a threaded end 233a and a rotating part 233b; the threaded end 233a is in threaded connection to the nut 234; the rotating shaft 233 is disposed in the through hole; the first knuckle 231b is disposed between the nut 234 and the second knuckle 232b; and the rotating part 233b is disposed in the second knuckle 232b. As one of the two arms 232 rotates, the rotating shaft 233 rotates as well, causing the second knuckle 232b to rotate around the rotating part 233b; as a result, the included angle between the arc-shaped support body 231 and the corresponding arm 232 is controlled to improve user's comfort. The threaded end 233a is in threaded connection to the nut 234 to prevent the rotating shaft 233 from sliding out of the first knuckle 231b.
Example 2
[0048] A second example of the travel pillow 300 is illustrated in FIG. 16. It is similar to Example 1, except for the following specific differences: the travel pillow 300 further comprises a hang tab 220a comprising a hole (not shown); the hang tab 220a is disposed on one side of the U-shaped filler 220 that props up the user's head. In use, gravity pulls down the hang tab 220a, so that the hang tab 220 covers a zipper in the middle of the U-shaped filler 220 and the U-shaped case 100; when not in use, the travel pillow 300 is hung on a hook through the hang tab 220a.
[0049] It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
