Description

Technical Field

[0001] The utility model belongs to the field of household articles, and in particular relates to a U-shaped neck pillow. Background Art

[0002] People often suffer from cervical pain when working, studying or traveling long distances. In order to relieve cervical pain, many people use U-shaped neck pillows. U-shaped neck pillows can provide certain support to the neck when people lean against the seat back, such as supporting the back or sides of the neck to relieve neck fatigue and make the neck more comfortable. However, the pillow body of this U-shaped neck pillow is relatively thick and the front end is open, which cannot effectively support the lower jaw, and basically does not play a supporting role for cervical pain caused by bowing the head for a long time. If the front opening is forcibly pulled together by the laces to increase the tension, because the pillow body is relatively thick and the internal filling has strong elasticity, it will drive the two sides of the U-shaped neck pillow to clamp inward and squeeze the neck blood vessels at the same time, resulting in insufficient blood supply to the head, which is very uncomfortable. Now there is also a thin and long strip chin support, which is easy to bend, can completely surround the neck for a week to effectively support the chin without squeezing the neck blood vessels, but this chin support is too thin and cannot provide effective support to the back and sides of the neck when resting against the seat back, and is not suitable for use when working, studying or resting on long journeys.

[0003] The utility model provides a U-shaped neck pillow, which can not only provide effective support for the back and sides of the neck when working, studying or resting during long-distance travel, but also provide effective support for the mandibular area without closing the opening of the U-shaped neck pillow, thereby preventing cervical vertebrae pain caused by bowing the head for a long time, and can also conveniently store the mandibular support. The design is ingenious and easy to use. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will further describe the technical solution of the utility model through implementation modes with reference to the accompanying drawings. It should be noted that the following implementation modes are used to help understand the utility model, but do not constitute a limitation to the utility model.

[0024] In the description of the present application, it should be understood that the terms "upper", "lower", "upper part", "lower part", "upper end", "lower end", "vertical", "top", "inside", "outside", "front", "back", etc., indicating orientations or positional relationships, are based on the orientations shown in the drawings or the orientations of objects in use, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application. Example 1

[0025] The utility model provides a U-shaped neck pillow, comprising a pillow body 1 and a chin rest 2, wherein the chin rest 2 is movably connected to the pillow body 1 through a wire-retracting and -releasing device; when the chin rest 2 is in use, the wire-retracting and -releasing device releases wires and provides continuous tensioning force to the chin rest 2, so that the chin rest 2 can be placed against the chin or cover the eye area; when the chin rest 2 is not in use, the wire-retracting and -releasing device retracts wires and stores the chin rest 2 on the outer surface of the pillow body 1, and fits tightly with the pillow body 1.

[0026] Specifically, Figure 1 As shown, the U-shaped neck pillow includes a pillow body 1, a chin rest 2 and two wire boxes 3, the wire boxes 3 are fixed to the outside of the pillow body 1, the box bodies of the two wire boxes 3 are provided with through holes for extending the ties 36 in the box bodies, the free ends of the ties 36 in the two wire boxes 3 extend out from the wire boxes 3 through the through holes, and the free ends of the two ties 36 are connected to the two ends of the chin rest 2.

[0027] The outer contour of the chin support 2 is basically consistent with the chin curve and the neck size, and can cover the area around the eyes; at the same time, the chin support 2 has a certain thickness and can support the chin. Its exterior is made of fabric and its interior is filled with sponge or other soft fillers.

[0028] As a preference, Figure 1 As shown, the two wire boxes 3 are directly fixed to the rear of the pillow body 1 or to the left and right sides near the rear. The chin rest 2 is stored behind the pillow body 1 when not in use and fits tightly with the pillow body 1. This arrangement makes it easier to store the chin rest 2 and makes the overall structure of the U-shaped neck pillow more compact. Example 2

[0029] On the basis of the first embodiment, in order to make the lace 36 be pulled out and retracted more smoothly, the wire box 3 is fixed to the pillow body 1 through the connection device of the wire box, and the wire box 3 can rotate freely relative to the connection device of the wire box. In this way, when the chin rest 2 is adjusted, the wire box 3 will also rotate together, and the lace 36 can be pulled out and retracted smoothly.

[0030] As an implementation method, Figures 2 to 5 As shown, a protrusion is provided at the bottom of the wire receiving box 3, and the connecting device of the wire receiving box includes a chassis 5. A hole slightly longer than the protrusion, or a groove for accommodating the protrusion is opened on the chassis 5. The protrusion at the bottom of the wire receiving box is extended into the hole or groove, so that the protrusion can rotate freely in the hole or groove. During installation, the protrusion is extended into the hole or groove of the chassis 5, and then the protrusion is limited to rotate freely in the hole or groove by a limiting device, and finally the chassis 5 is directly fixed on the pillow body 1. If the U-shaped neck pillow is a PVC inflatable pillow, the chassis 5 and the pillow body 1 can be directly connected by high-frequency hot melting. Of course, the chassis 5 can also be directly fixed on the pillow body 1 by other connection methods that can be easily thought of by those skilled in the art.

[0031] Preferably, the limiting device is a threaded hole opened from bottom to top in the middle of the bottom of the protrusion, the hole on the chassis 5 is a through hole, or a screw mounting groove is opened from the bottom of the hole to the lower surface of the chassis 5, the nut size of the screw is larger than the outer diameter of the hole, and the protrusion is limited in the hole by the screw; or, the limiting device is a claw arranged at intervals at the bottom of the protrusion and extending from bottom to top toward the outside of the protrusion; after the protrusion passes through the hole of the chassis 5, the claw is clamped at the end of the hole on the side away from the wire receiving box 3. Example 3

[0032] On the basis of Examples 1 and 2, Figure 2-8 As shown, the connection device of the wire take-up box includes a chassis 5 and a pressure plate 6, and the protrusion is a cylinder 31 arranged at the bottom of the wire take-up box 3. The chassis 5 is a circular plate, and a through hole 51 is opened in the middle of the circular chassis. On the lower surface of the chassis 5, an annular boss 52 is arranged cocentrically with the through hole 51, and the inner side of each boss 52 forms an accommodating space 555. In order to support the cylinder 31 and make it rotate more smoothly, a bearing 7 is also arranged in the accommodating space 555. In order to make the cylinder 31 always rotate freely in the accommodating space 555, a limit device is also arranged on the cylinder 31.

[0033] The pressure plate 6 is provided with a groove 61 for accommodating the boss 52. The pressure plate 6 is also a circular plate, and the middle of the pressure plate 6 is sunken from top to bottom to form the groove 61, and the diameter of the groove 61 is slightly larger than the outer diameter of the boss 52.

[0034] Preferably, the above-mentioned limiting device is a threaded hole from bottom to top arranged in the middle of the bottom of the protrusion or cylinder 31. The cylinder 31 passes through the through hole 51 and the bearing hole, and the screw 8 is screwed into the threaded hole. Since the size of the screw nut is larger than the bearing hole, the screw nut is limited to the side of the bearing 7 away from the wire receiving box 3. Therefore, the setting of the screw 8 limits the cylinder 31 in the accommodating space 555, and plays a role in connecting the wire receiving box 3 and the chassis 5. Alternatively, the limiting device can also be a claw that is arranged at intervals at the bottom of the cylinder 31 and extends from bottom to top toward the outside of the cylinder 31; the claw passes through the bearing hole and is clamped on the side of the bearing 7 away from the wire receiving box 3.

[0035] In order to further limit the position of the bearing 7, a stopper 522 extending from bottom to top toward the center of the chassis 5 is further provided at the inner lower part of the boss 52, and the upper surface of the stopper 522 is at a certain height from the lower surface of the boss 52. The upper surface of each stopper 522 and the inner side of each boss 52 form an accommodation space for accommodating the bearing 7, and the inner side of each stopper forms an accommodation space for accommodating the screw 8 or the claw.

[0036] During installation, the cylinder 31 at the bottom of the wire-receiving box 3 is passed through the through hole 51 and the bearing hole in the middle of the chassis 5, and then the wire-receiving box is connected to the chassis by screws 8 or claws. Finally, the pressure plate 6 is fixedly connected to the chassis 5, and the pressure plate 6 is directly fixed on the pillow body 1, so that the wire-receiving box 3 is directly fixed on the pillow body 1.

[0037] In order to facilitate the quick connection between the chassis 5 and the pressure plate 6, preferably, the chassis 5 and the pressure plate 6 are connected by a snap connection. Figure 6 As shown, a notch 62 is provided on the side wall of the groove 61 corresponding to the position of the boss 52 , and an inclined platform 63 is provided above the notch 62 and extends outward from the inner side of the groove 61 to the upper surface of the pressure plate 6 .

[0038] like Figure 4 and 5 As shown, the bosses 52 on the lower surface of the chassis 5 are arranged at intervals in the circumferential direction, and the outer side of the bosses 52 has a locking protrusion 521 extending outward from bottom to top. Under the pressure of the ramp 63, each locking protrusion 521 on the lower surface of the chassis 5 moves inward and smoothly extends into the groove 61. When the locking protrusion 521 completely passes through the ramp 63, the locking protrusion 521 bounces outward through the notch 62, and at this time, the locking protrusion 521 is locked at the bottom of the pressure plate 6, so that the chassis 5 is locked on the pressure plate 6.

[0039] In order to strengthen the chassis 5, another boss 53 is provided between two adjacent bosses 52. The bosses 52 and 53 are concentric with the through hole 51, and the inner diameter and outer diameter of the boss 52 are respectively equal to the inner diameter and outer diameter of the boss 53; the bottom surface of the boss 53 is higher than the bottom surface of the boss 52. This arrangement can not only strengthen the chassis 5, but also allow the boss 52 to have a certain deformation space, so that the clamping protrusion 521 can smoothly extend into the groove 61.

[0040] For the sake of aesthetic design and ease of processing, preferably, the bosses 52 and 53 on the lower surface of the chassis 5 are arranged at equal intervals, and the number of each is four.

[0041] Through the above arrangement, the pressure plate 6 is first fixed on the pillow body 1 , and then the bottom plate 5 is clamped with the pressure plate 6 , so that the wire take-up box 3 is directly fixed on the pillow body 1 . Example 4

[0042] On the basis of Example 3, in order to protect the integrity of the pillow body 1 and connect the pillow body 1 to the wire receiving box 3 without being damaged, the U-shaped neck pillow further includes a cloth cover 4. Figure 8As shown, the shape of the cloth cover 4 matches the shape of the pillow body 1, and the cloth cover 4 is sleeved on the pillow body 1. The cloth cover 4 has holes corresponding to the rear of the pillow body or on both sides close to the rear, the pressure plate 6 is arranged on the inner side of the cloth cover 4, and the bottom plate 5 is arranged on the outer side of the cloth cover 4. The boss 52 on the lower surface of the bottom plate 5 passes through the hole on the cloth cover 4 and extends into the groove 61, and the clamping protrusion 521 is clamped on the bottom of the pressure plate 6, so that the cloth cover 4 is fixed between the bottom plate 5 and the pressure plate 6, so that the take-up box 3 is indirectly fixed on the pillow body 1 through the cloth cover 4.

[0043] Such a configuration can not only protect the integrity of the pillow body 1 , but also keep the pillow body 1 clean, and also facilitate the installation and removal of the wire take-up box 3 .

[0044] like Figure 2 and 3 As shown, in embodiments 1 to 4, the wire take-up box 3 includes an upper box body 32 and a lower box body 33, a limiting column 321 is provided at the bottom of the upper box body 32; a winding disk 34 is provided in the lower box body 33, a spring spring 35 is provided in the winding disk 34, a through hole is provided at the center of the winding disk 34, the limiting column 321 passes through the through hole on the winding disk and the center hole of the spring spring in sequence and extends to the upper bottom surface of the lower box body 33, the inner circle end of the spring spring 35 is clamped with the limiting column 321, the outer circle end of the spring spring 35 is clamped with the winding disk 14, the end of the lace 36 away from the free end is connected to the winding disk 34 and wound on the winding disk 34, and the lace 36 can be retracted and wound on the winding disk 34 under the action of the spring spring 35. A circular hole consisting of two semicircular arc holes is opened at corresponding positions on the upper box body 32 and the lower box body 33 of the wire take-up box, and the free end of the lace 36 extends out of the circular hole.

[0045] The U-shaped neck pillow provided by the utility model provides a continuous and moderate pulling force to the chin support through the wire-retracting and releasing device, so that the U-shaped neck pillow can not only provide effective support to the back and sides of the neck during work, study or long-distance travel, but also provide effective support to the chin without closing the opening of the U-shaped pillow, preventing cervical vertebrae pain caused by bowing the head for a long time, and the chin support can also cover the eye area and be used as an eye mask, with multiple functions. At the same time, the wire-retracting box can rotate freely relative to the connecting device of the wire-retracting box, which is convenient for retracting and releasing the wire, so that the chin support can be easily stored at the back of the pillow body, with a compact structure, ingenious design and convenient use.
