Description

Floor fixed rolling pillow

The present invention relates to a floor-type rolling pillow, and more particularly, to a floor-type rolling pillow capable of continuously maintaining a comfortable and correct sleeping posture by naturally moving the central axis of the cushion member by a user's movement.

In general, the basic posture of sleeping is a posture lying on the floor with both shoulders on the floor, and it is known that even if you can sleep only 50% of the sleep time with this posture, there is no problem with your sleep health.

Typically, when you lie down for sleep, you will receive gravity all over your body, and an average of 20 to 30 turns will occur.

At this time, when the user who is using the normal pillow is turned back, the central axis of the user is changed, so that the neck and shoulders are twisted, and accordingly, power is applied to the neck or shoulder, thereby preventing a comfortable sleep.

As a related prior art, there is a pillow for correcting sleep posture disclosed in Korean Registered Utility Model Publication No. 20-0469632.

This prior art has an upward wall extending upwardly to the left and right of the upper surface of the body supporting the user's head, whereby the user's head interferes with the upward wall and prevents the user from rolling to the side, so that the user returns to the side. It is a technique that prevents you from lying down.

However, in the prior art as described above, since the bottom surface of the body is formed flat and the user's head and the upward wall interfere when the user turns to the side, the sleeping position is fixed in the direction that the user's face is always looking at the sky. Rather, there is a problem that can cause strain on the cervical spine and spine.

The present invention was created in order to improve the problems of the prior art as described above, and in the sleeping state, a floor capable of continuously maintaining a comfortable posture by maintaining the central axis of the user through the movement of the cushion member when the user is turned over. The aim is to provide a stationary rolling pillow.

Specifically, it is an object of the present invention to provide a floor-type rolling pillow that can be maintained in a correct posture without twisting a shoulder or neck by allowing the movement of the cushion member in a lengthwise or widthwise direction according to a user's movement.

In addition, an object of the present invention is to provide a floor-type rolling pillow that can be used in a fixed state by selectively limiting the movement of the cushion member.

In order to achieve the above object, the floor-type rolling pillow according to one embodiment of the present invention provides a supporting force in a state placed on the floor, and a groove-shaped receiving space forming an arc shape on the upper surface is formed to form a user's head A base member accommodating the accommodation space; A cushion member movably seated in the accommodation space of the base member to support a user's head; And a cushion moving member that movably couples the cushion member to the base member and allows movement of the cushion member by a user's movement.

For example, the cushion moving member may include: a guide rail formed in at least one of a length direction and a width direction of an upper surface of the receiving space of the base member to provide a movement path of the cushion member; A slider movably coupled to the guide rail and fixed to the bottom surface of the cushion member to move along the guide rail; And it can be configured to include a roller that is rotatably installed on the upper surface of the base member to support the slider.

For example, the guide rail includes a horizontal rail formed in a groove shape along the longitudinal direction of the base member, and the roller is formed in a wheel shape and rotates forward or reverse in a direction corresponding to the longitudinal direction of the horizontal rail. It may be configured to include a guide wheel for moving the slider along the horizontal rail while rotating.

In addition, the guide rail, a horizontal rail formed in a groove shape along the longitudinal direction of the base member; And a vertical rail formed in a groove shape along the width direction of the base member to form an orthogonal state with the horizontal rail, and the roller is formed in a ball shape and defined in a direction corresponding to the horizontal rail and the vertical rail. It may be configured to include a guide ball for moving the slider along the horizontal rail and the vertical rail while rotating or reverse rotation.

Further, the cushion moving member may further include a roller brake that selectively restricts the rotation of the roller and selectively allows the slider to move.

For example, the roller brake may be configured to include a pressing protrusion that is installed on the base member and prevents the roller from rotating arbitrarily while being caught by a portion of the roller by the user.

In the floor-type rolling pillow according to an embodiment of the present invention, the cushion member supporting the user's head is allowed to move by the user's movement through the cushion moving member, even when the user's backseat occurs in the sleeping state. Through the movement of the user, the central axis of the user is maintained, so that a comfortable and correct sleeping posture can be continuously maintained.

Specifically, in the present invention, since the cushion member moves along the guide rail by the roller together with the slider, the cushion member can be smoothly moved by the user's movement, and accordingly, the central axis is maintained even by the user's movement, so that the shoulder or neck Sleep position can be maintained without distortion.

In addition, in the present invention, when the roller is composed of a guide wheel, the cushion member may be allowed to move in the horizontal direction, and when the roller is composed of a guide ball, the cushion member may move in the horizontal direction as well as in the vertical direction.

In addition, according to the present invention, the rotation of the roller can be selectively limited by the roller brake, so that the cushion member can be easily switched to a fixed type if necessary.

Hereinafter, the present invention will be described in more detail with reference to examples.

The examples presented are only specific examples of the invention and are not intended to limit the scope of the invention.

<실시예><Example>

In order to analyze the effect induced by the floor-type rolling pillow having a structure as shown in FIGS. 1 to 5, the first floor-type rolling pillow provided with a guide wheel-shaped roller and the second floor provided with a roller-shaped guide ball After using a fixed rolling pillow to sleep for a certain period of time, an epidemiological study of the body changes of the users was performed.

(1) 사용자 선택(1) User selection

In order to analyze the effects of the floor-fixed rolling pillow on the body changes of users, 16 males in their 30s who have no history of musculoskeletal disorders in their neck or waist and who are in good health were selected as users and carried out physical epidemiology studies. In order to minimize errors, all were selected as people using the right hand, and the anthropometric values of the users are shown in Table 1 below.

(2) 목 자세 분석(2) neck posture analysis

In order to analyze the effect induced when using a floor-type rolling pillow, changes in the user's neck posture during sleep were analyzed, and at this time, commercially available pillows and memory foam pillows were used as controls.

For neck posture analysis, all 16 users are required to wear comfortable clothing and find and mark the reference points (ear ball point, shoulder point point, back head point, neck back point) necessary for measuring neck posture change, and then use the electrode attachment point as alcohol. It was sterilized (alcohol preparation), and each surface electrode of six channels was attached.

Mark the reference points needed to measure neck posture change, take the picture by letting the user stand upright, and find the most comfortable posture in the supine position by first and second floor fixed rolling pillows, normal pillows or memory foam pillows Then, the lying neck position was taken again while maintaining the most comfortable position. To reduce the error of shooting, the camera was fixed to a tripod so that there was no position change.

For reference, an important element of the function of the floor-mounted rolling pillow or pillow is to maintain the natural posture of the neck while the user is standing. Maintaining the natural posture of the neck means that the 7 cervical vertebrae are aligned in a straight line to form a cervical curvature. However, if the cervical spine is not properly aligned and deviates from the center line a lot, shear force is generated in the opposite direction to the direction in which the cervical spine is distorted. At this time, the shearing force refers to a force acting in parallel along the surface so that the size is the same and the directions are opposite to each other based on a specific surface in the object. If an inappropriate pillow is used, cervical curvature may be disturbed, and Shear force occurs in the direction opposite to the disheveled direction, and when shear force occurs, it can be said that the stability of the cervical vertebra is broken. Therefore, it can be considered that the cervical spine is stable when the woodcarving degree is close to 0 °.

Based on the conditions as described above, sleep was performed for 3 hours, and the amount of change in neck angle in the supine position was measured and expressed as an average value, and the results are shown in Table 2 below.

As shown in Table 2, it was confirmed that the amount of change in neck angle was significantly lower in the case of users who had to sleep using the floor-type rolling pillow, compared to those with the pillow and memory foam pillow. Could. In particular, it was confirmed that the amount of change in the neck angle of the users who took the sleep by using the second floor fixed rolling pillow equipped with the guide ball-shaped roller was lower, thereby maintaining the most natural posture.

This is the most natural posture because it maintains a proper lying posture by automatically aligning to maintain a sleeping position and keeping the balance of the neck even when the posture is changed when sleeping by using the floor-type rolling pillow of the present invention. It was judged to be able to maintain.

(3) 체압분포 측정(3) Body pressure distribution measurement

Body pressure, which is the pressure applied to the head surface, was measured using a pressure sensor to measure how evenly the body pressure is distributed when the first and second floor-type rolling pillows, a general pillow, or a memory foam pillow are cut and laid. The pressure measurement points are two points (S1 and S2) where the posterior head point meets, two points located up and down parallel to the posterior head protrusion point (S3 and S4), the semi-parpical muscles (Semispinalis capitis, S5 and S6), the lateral head Measured at a total of eight points (S1 and S8) at two points (S7 and S8) based on the imaginary line parallel to the point, and the thickness is negligible without directly attaching the sensor to the user's head surface to reduce errors when measuring. It was measured after attaching the sensor using a thin cloth.

For reference, the fact that the body pressure is high in a specific part is that the floor-mounted rolling pillow or pillow does not distribute the weight of the head, and local pressure occurs, and if this local pressure is maintained, it is possible that it may cause pain at the pressure point. It means that there is.

In the analysis of muscle activity, the head surface body pressure (g / cm ³ ) was measured to find out how much the muscle activity in the reclined position is distributed using a floor-fixed rolling pillow or pillow, and the results are shown in the table below. It is shown in 3.

As shown in Table 3, it was confirmed that the first and second floor-type rolling pillows, general pillows, and memory foam pillows both had pressure applied to the back through points S1 and S2 and the back through protrusions S3 and S4. , In the case of the memory foam pillow, pressure was intensively applied to a specific portion such as a back through point due to the characteristics of the shape, and thus it was confirmed that the body pressure was relatively higher than that of the first and second floor fixed rolling pillows and general pillows.

However, in the case of the users wearing the first and second floor-type rolling pillows, it was confirmed that the body surface pressure was evenly distributed to maintain a balanced posture compared to a user using a normal pillow or a memory foam pillow.

In addition, when the body is turned during sleep, in the case of the first and second floor-type rolling pillows, the body shape is not evenly distributed because the body pressure is not concentrated in one place by maintaining the proper shape to support the head as a whole. On the other hand, when using a general pillow or a memory foam pillow, it was confirmed that body pressure is frequently concentrated in one place.

Through the above results, the floor-fixed rolling pillow according to the embodiment forms a structure in which the cushion member moves smoothly by the movement of the user because the cushion member moves along the guide rail by the roller together with the slider when used, Accordingly, it was confirmed that the central axis is maintained even by the user's movement to help maintain the correct sleeping position without distorting the shoulders or neck.

Particularly, in the case of the second floor-type rolling pillow equipped with a guide wheel type roller, it was confirmed that the cushion member has an effect of moving in the vertical direction as well as in the horizontal direction, thereby helping to maintain a more proper sleeping posture.

The above-described embodiments are for illustration only, and those skilled in the art to which the above-described embodiments belong can easily be modified into other specific forms without changing the technical idea or essential characteristics of the above-described embodiments. You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.

The scope to be protected through the present specification is indicated by the claims, which will be described later, rather than the detailed description, and should be interpreted to include all the changed or modified forms derived from the meaning and scope of the claims and their equivalent concepts. .
