Description

Automatic height-adjusting pillow

[0001] The present invention relates to an automatic height-adjusting pillow, and more particularly, to an automatic height-adjusting pillow whose height is flexibly adjusted according to changes in the user's posture while sleeping.

[0002] In modern society, the use of cutting-edge IT devices such as personal computers and cell phones has become a daily routine, leading to the habit of keeping one's head down all day, leading to numerous people complaining of shoulder and neck pain.

[0003] Patients with neck and shoulder pain complain of worse pain, especially in the morning after waking up, and the biggest reason for this is believed to be the pillow they slept on all night that does not fit their body.

[0004] In general, a pillow supports the head to induce a comfortable sleep, secures the stability of the body structure by protecting the cervical spine, and facilitates breathing and blood circulation. However, if you continue to use a pillow that is too high or too low without considering your body, it can cause a flat neck, so-called turtle neck, or the alignment of the spine can change, causing numbness or pain.

[0005] In general, when lying on your side (hereinafter referred to as the 'side posture'), the height of the pillow should be about 10 to 15 cm higher due to the height of your shoulders so that the cervical spine of your torso and head can comfortably be maintained in a 'straight' shape. When lying down looking straight at the ceiling (hereinafter referred to as the 'upright posture' or 'front posture'), your shoulders fall down and your head directly touches the pillow, so it should be lowered by about 6 to 8 cm again so that the cervical spine shape when lying down becomes a 'C' shape, which is a normal, comfortable posture.

[0006] However, existing pillows are manufactured in a standardized form without considering individual physical characteristics or sleeping posture. Therefore, users have no choice but to adjust their body height and shape to the standardized pillow while sleeping. Continued use of these pillows can lead to the aforementioned flat neck, also known as turtle neck, or spinal misalignment, leading to numbness and pain.

[0007] To address this issue, the inventors of the present invention have developed a conventional technology that supports a height-adjusting member (variable member) between the upper and lower plates by the elastic force of a tension spring. This configuration allows the height to be adjusted based on the difference in load applied to the pillow when lying on one's side or upright, thereby maintaining proper posture while sleeping.

[0008] However, the conventional technology described above had a problem in that the displacement speed was irregular and it did not provide a comfortable feeling when getting on and off because the height was controlled only by the elasticity of the tension spring. In addition, the automatic height-adjusting pillow according to the conventional technology had a problem in that the lever ratio was applied as the angle of the 'X' frame structure supporting the upper and lower plates changed (as the upper and lower plates got closer), causing a phenomenon in which the inherent elasticity of the spring was rapidly reduced. In other words, there was a problem in that the spring could not appropriately provide the force to adjust the height according to the change in the user's posture.

[0009] Referring to Figure 1(a), this is an experiment assuming the user's head load to be 6 kg (the standard human head weight determined based on various papers and empirical data), and the graph in ① shows the force required for a 6 kg load, the graph in ② shows the force that a single tension spring with a constant elastic coefficient can generate, and the graph in ③ shows the size of the insufficient force of ② with respect to ①.

[0010] Looking at it, it can be seen that the graph shapes of ① and ② have many parts that do not match each other, and because a single tension spring with a constant elastic coefficient is used, it can be seen that it is difficult for the elastic force provided by the tension spring to sufficiently provide the force necessary to support the load applied to the pillow and adjust the height while the user's posture changes from the frontal posture to the side posture.

[0011] Accordingly, when the user's posture changes from a frontal posture to a side posture or from a side posture to a frontal posture during sleep, the tension spring may not provide the height adjustment unit with the appropriate force to adjust the height accordingly, which may cause the user to feel uncomfortable and uncomfortable in the posture.

[0012] Another conventional technology involves supporting a variable member (height-adjusting member) between the upper and lower plates by the driving force of a drive cylinder. This conventional technology, by using a drive cylinder, can provide a more regular displacement speed and stable driving force when controlling height.

[0013] However, these conventional technologies also had the problem of not being able to provide adequate power to adjust the height according to changes in the user's posture.

[0014] In other words, referring to Fig. 1(b), this is an experiment assuming a user's head load of 6 kg, the graph of ① shows the force required for a 6 kg load, the graph of ②' shows the force that a certain driving cylinder can produce, and the graph of ③ shows the size of the insufficient force of ② with respect to ①.

[0015] Looking at it, it can be seen that the graph shapes of ① and ②' have many parts that do not match each other, and because a driving cylinder that provides a constant driving force is used, there was a limit to providing a constant driving force of the driving cylinder to support the load applied to the pillow and adjust the height while the user's posture changes from a frontal posture to a side posture.

[0016] Accordingly, when the user's posture changes from a frontal posture to a side posture or from a side posture to a frontal posture during sleep, the pillow may not provide enough force to appropriately adjust the height of the variable portion accordingly, which may cause the user to feel uncomfortable and uncomfortable in their posture.

[0017] The present invention is intended to solve the above problems, and provides an automatic height-adjusting pillow whose height can be flexibly adjusted by a difference in the load applied to the pillow according to a change in the user's posture, and which allows the user's neck to maintain a proper shape through such height adjustment.

[0018] In addition, the purpose is to provide an automatic height-adjusting pillow that provides an appropriate amount of force required for a change in the height of the pillow according to a change in the user's posture, so that the user can feel comfortable.

[0019] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0020] According to one aspect of the present invention, an automatic height-adjusting pillow is provided.

[0031] At this time, the elastic adjustment axis may be provided with the main elastic member and the auxiliary elastic member together between the first pressing member and the second pressing member as a single axis.

[0032] At this time, the elastic adjustment shaft may be a plurality of elastic adjustment shafts arranged in parallel at different positions, and each elastic adjustment shaft may be provided with the main elastic member and the auxiliary elastic member.

[0033] At this time, the variable part includes a first support member having one side fixed at one side of the upper surface of the lower plate and hinge-rotatably installed through a first-first hinge, and the other side installed at the other side of the lower surface of the upper plate and hinge-rotatably installed through a first-second hinge; a second support member having one side fixed at one side of the lower surface of the upper plate and hinge-rotatably installed through a second-first hinge, and the other side installed at the other side of the upper surface of the lower plate and hinge-rotatably installed through a second-second hinge; and the first support member and the second support member are connected through a link member and may have an “X” shape.

[0034] At this time, the variable portion may be positioned forward with an imaginary line dividing the automatic height-adjusting pillow into front and rear.

[0035] At this time, the upper plate portion includes an upper plate rail portion having a length on a bottom surface; the lower plate portion includes a lower plate rail portion having a length on an upper surface; the first support portion includes an upper guide block integrally fixed to the first-second hinge, and the upper guide block is slidably coupled to the upper plate rail portion; and the second support portion includes a lower guide block integrally fixed to the second-second hinge, and the lower guide block can be slidably coupled to the lower plate rail portion.

[0036] At this time, the height adjustment unit may include a height adjustment knob having a shape that a user can grip; a height adjustment shaft having one end rotatably connected to the height adjustment knob; a first support block fixedly connected to the upper part or the lower part and having the height adjustment shaft passing therethrough and rotatably supported; a support pipe having an end side of the height adjustment shaft threadably connected to an inner circumference; a connection block integrally formed with the support pipe; a restraint block slidably connected to one end of the upper plate rail part or the lower plate rail part; and a connection frame integrally connected to the connection block while integrally connecting the restraint block and the upper guide block or the lower guide block.

[0042] According to the above configuration, the automatic height-adjusting pillow according to the present invention has the effect of allowing the user's cervical spine to maintain a correct shape even while sleeping by changing the height of the variable portion supporting the upper portion accordingly when the load applied to the upper portion changes due to a change in posture of the user while sleeping.

[0043] In addition, the driving unit that provides elastic driving force for changing the height of the variable section is composed of a main elastic member and an auxiliary elastic member with different elastic forces and driving points, and has the effect of flexibly responding to changes in the load applied to the upper part due to changes in the user's posture, thereby providing an appropriate elastic driving force.

[0044] Additionally, the height of the pillow required can be stably changed without separate operation according to changes in load due to changes in posture while sleeping, which has the effect of allowing the user's neck to maintain the correct shape.

[0045] Additionally, the height adjustment section allows the user to adjust the height of the pillow to suit their body type, including shoulder height and head size, when using it for the first time, allowing each user to select a pillow height that suits their sleeping preferences.

[0046] In addition, the elasticity of the main elastic member and auxiliary elastic member constituting the driving unit can be adjusted through the elasticity adjustment unit, so that not only can an elastic driving force be provided that is tailored to each user, reflecting the user's head weight, etc., but also has the effect of stably providing an elastic driving force through readjustment of the elastic driving force over time.

[0047] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present invention or the composition of the invention described in the claims.

[0063] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts irrelevant to the description are omitted in the drawings, and the same reference numerals designate identical or similar components throughout the specification.

[0067] When a component is said to be "in front of," "behind," "above," or "below" another component, this includes not only being placed "in front of," "behind," "above," or "below" the other component in direct contact with it, but also if there is another component intervening therebetween. Furthermore, when a component is said to be "connected" to another component, this includes not only being directly connected to one another, but also being indirectly connected to one another, unless there are special circumstances.

[0068] In addition, in explaining the present invention, specific descriptions of related known functions or configurations will be omitted in order to avoid obscuring the gist of the present invention.

[0069]

[0070] Hereinafter, an automatic height-adjusting pillow according to one embodiment of the present invention will be described with reference to the drawings.

[0071] Referring to FIGS. 2 to 13, as illustrated, an automatic height-adjusting pillow (1) according to one embodiment of the present invention is configured to automatically adjust the height of the pillow so that the user's cervical spine can maintain a correct posture even when the user's posture changes while sleeping, that is, when the user's posture changes from a straight posture (front posture) looking at the sky to a posture when lying on the side (side posture).

[0072] To this end, an automatic height-adjusting pillow (1) according to one embodiment of the present invention largely includes an upper portion (10), a lower portion (20), a variable portion (30), and a driving portion (40). In addition, the pillow may be configured to further include a height-adjusting portion (50) for adjusting the height of the pillow, and an elasticity-adjusting portion (60) for adjusting the elastic driving force of the driving portion (40).

[0073] Meanwhile, the upper part (10) includes a cushion member (3) on which the user's head rests. In addition, the upper part (10), the cushion member (3), the lower part (20), and the variable part (30) are internally included and a cover (2) that surrounds them are included to form an automatic height-adjusting pillow (1) that is actually used by the user.

[0074] For convenience of explanation, most of the covers (2) and cushion members (3) in the city are excluded, but it is stated that these covers (2) and cushion members (3) are components that constitute the automatic height-adjusting pillow (1) of the present invention.

[0075] Meanwhile, in the automatic height-adjusting pillow (1) according to one embodiment of the present invention, the height of the pillow (1) is automatically adjusted as the height of the variable portion (30) changes according to a change in the user's posture. This change in the height of the variable portion (30) is implemented through the correlation between the user's head load and the elastic driving force provided by the driving portion (40).

[0076]

[0077] Again, referring to the drawings, the automatic height-adjusting pillow (1) according to one embodiment of the present invention will be examined in more detail as follows.

[0078] First, the lower part (20) is a panel-shaped part having a width and length set to be placed and supported while in contact with the floor surface of the place where the user sleeps. The floor surface refers to a place where a pillow, such as a bed, is placed.

[0079] At this time, the lower part (20) supports all loads including the variable part (30) and the upper part (10) located at the top and the load of the user's head while sleeping, while also maintaining the center to prevent the pillow from tilting during use.

[0080] For this purpose, it would be desirable for the lower part (20) to have a width and length that can at least include the user's head.

[0081] Meanwhile, the lower part (20) may further include a cushion member (not shown) at the bottom separately from the upper cushion member (3) as needed, and may have a shape including a flange part that is bent upwards while being rounded in whole or in part so that the cover (2) can be stably wrapped.

[0082] In addition, the lower plate (20) may include a lower rail portion (23) integrally joined to the upper surface, a lower through hole (21) for air circulation, and a lower joining hole (22) for joining internal components.

[0083] The lower penetration hole (21) is a shape in which a portion of the lower part (20) is cut off and can have various shapes such as a circle, an oval, a rectangle, etc., and together with the upper penetration hole (11) of the upper part (10) described later, it can provide an air passage through which air inside the pillow can pass according to changes in the user's posture.

[0084] Meanwhile, the lower joint (22) enables the internal components to be stably joined to the lower part (20) by the joining member (4).

[0085] In addition, the upper part (10) is installed in a movable manner on the upper part of the lower part (20) described above in a panel shape having a width and length of a setting, so as to support the head load of the user using the pillow (1).

[0086] At this time, the upper part (10) is provided with a cushion member (3, Figs. 5 and 7) on which the user's head rests, and has a size set to prevent the pillow from tilting during use. To this end, it is preferable that the upper part (10) have a width and length that can at least accommodate the user's head.

[0087] Furthermore, the cushion member (3) may be of a shape that changes to the shape of the user's head when the user's head is placed on it, or may be of a fixed shape with a predetermined shape. The cushion member (3) may have various shapes as long as it can support the user's head while maintaining the correct shape of the cervical spine.

[0088] Meanwhile, the upper part (10) may have a shape including a flange part that is bent downwards while having all or part of the edge of the end rounded so that the cover (2) does not bend due to the weight of the user's head.

[0089] In addition, the upper plate (10) may include an upper rail portion (13) to be described later integrally joined to the lower surface, and may include an upper through hole (11) for air circulation and an upper joining hole (12) for joining internal components.

[0090] The upper penetration hole (11) is a shape in which a portion of the upper part (10) is cut off and can have various shapes such as a circle, an oval, a rectangle, etc., and together with the lower penetration hole (21) of the lower part (20) described above, it can provide an air passage through which air inside the pillow can pass according to changes in the user's posture.

[0091] Meanwhile, the upper joint (22) enables the internal components to be stably joined to the upper part (10) by the joining member (4).

[0092] Meanwhile, the cover (2) that covers the outer surface of the upper part (10) and the lower part (20) and directly contacts the user's head may have a wrinkled Javara-shaped shape so that the height of the pillow (1) can be stably changed according to the change in height of the variable part (30) described later.

[0093] Meanwhile, preferably, referring to FIGS. 5 and 7, the front end (a) of the upper part (10) described above is formed to protrude toward the user's body more than the front end (b) of the lower part (20). In other words, the front end (a) of the upper part (10) and the front end (b) of the lower part (20) have a gap (d1) and form a space.

[0094] As shown in Fig. 7, when a user using a pillow (1) lies down in a side position, the shoulder is placed on the floor and supports the head. At this time, in order for the variable part (30) of the pillow (1) to accurately respond to the load of the head, it is preferable that the user's head be positioned as close to the center of the pillow (1), that is, the vertical upper part of the variable part (30), and for this purpose, the user's shoulder part may be positioned to dig into the lower side of the pillow (1) due to the human body shape. At this time, the user's shoulder part can dig into the lower side of the pillow (1) through the space formed by the gap (d1) between the front end (a) of the upper part (10) and the front end (b) of the lower part (20) described above, so that the user can maintain a stable posture without discomfort while sleeping.

[0095]

[0096] Meanwhile, as described above, the automatic height-adjusting pillow (1) according to one embodiment of the present invention automatically adjusts its height so that the user's cervical spine can maintain a correct posture according to changes in the user's posture while sleeping.

[0097] At this time, the variable part (30) supports the user's head load while adjusting the height.

[0098] This variable portion (30) supports the height of the upper portion (10) to vary depending on the load applied to the upper portion (10), and is installed between the upper portion (10) and the lower portion (20). As a preferred example, the variable portion (30) may have an “X” shaped frame structure.

[0099] Meanwhile, the automatic height-adjusting pillow (1) of the present invention has a variable portion (30) that is lowered in height when pressed by the head load in a frontal posture, and then automatically increases in height when the head load is reduced while changing the posture to a side posture.

[0100] At this time, the driving unit (40) always provides elastic driving force to the variable unit (30) in the direction in which the height of the variable unit (30) increases.

[0101] In the frontal posture, the load on the head is greater than the elastic driving force of the driving unit (40), so the head is pressed and the height of the pillow is lowered. In the side posture, as the load on the head is reduced, the elastic driving force of the driving unit (40) supports the load, and as the height of the variable unit (30) increases, the height of the pillow increases.

[0102] Meanwhile, the automatic height-adjusting pillow (1) according to one embodiment of the present invention has a driving unit (40) implemented through a plurality of elastic members. Preferably, referring to FIGS. 4 and 10a and 10b, the driving unit (40) applied to the present invention is composed of multiple elastic members including a main elastic member (41) and at least one auxiliary elastic member (42).

[0103] At this time, the auxiliary elastic member (42) has an elasticity different from that of the main elastic member (41), but is arranged to provide an elasticity in the same direction.

[0104] That is, the elastic force of the main elastic member (41) and the auxiliary elastic member (42) together generate an elastic driving force that pushes in the direction in which the height of the variable part (30) increases, and the main elastic member (41) and the auxiliary elastic member (42) have different elastic coefficients and driving points.

[0105] Meanwhile, as shown in FIGS. 10a and 10b as an example, in the city, the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) are shown as being arranged on the same line along a concentric axis, but of course, the main elastic member (41) and the auxiliary elastic member (42) may be arranged in separate positions, as needed.

[0106] An automatic height-adjusting pillow (1) according to one embodiment of the present invention, as described above, is composed of a plurality of elastic members including a main elastic member (41) and at least one auxiliary elastic member (42) in which the driving member (40) is composed of a main elastic member (41) and at least one auxiliary elastic member (42), and the main elastic member (41) and the auxiliary elastic member (42) provide different elastic forces and driving points.

[0107] Accordingly, the elastic driving force provided from the driving unit (40) to the variable unit (30) is characterized in that it can appropriately provide the force required to support the change in the user's head load when the user's posture changes while sleeping.

[0108] Meanwhile, it goes without saying that two or more auxiliary elastic members (42) may be applied as needed, and it goes without saying that the additional auxiliary elastic members (42) may also be placed on the same concentric axis or in separate positions.

[0109] Referring to Fig. 11, in Fig. 11, a configuration of one main elastic member (41) and one auxiliary elastic member (42) was tested as an example, and the test assumed that the user's head load was 6 kg. At this time, the graph of ① shows the force required for a load of 6 kg, the graph of ② shows the force that the main elastic member (41) and the auxiliary elastic member (42) can generate, and the graph of ③ shows the difference in force of ② with respect to ①.

[0110] If we look at it, we can see that the graph shape of ② has many parts that are similar to the graph shape of ①, as it is implemented with multiple elastic members.

[0111] In other words, the automatic height-adjusting pillow (1) according to one embodiment of the present invention shows that the elastic force provided by the main elastic member (41) and the auxiliary elastic member (42) can stably provide the force required to adjust the height of the variable portion (30) while supporting the load applied to the pillow while the user's posture changes from a frontal posture to a side posture.

[0112] Accordingly, the automatic height-adjusting pillow (1) of the present invention allows the user to sleep comfortably without feeling any discomfort by having the driving unit (40) appropriately provide the force required for a change in the height of the pillow according to a change in the user's sleeping posture.

[0113] Through Fig. 11, it can be confirmed that if another auxiliary elastic member (42) having different elasticity and driving point is applied, the curve (①) of the force required according to the change in the head load and the curve (②) of the driving elasticity provided by the driving unit (40) can be more stably matched according to the change in the head load. Accordingly, it goes without saying that the automatic height-adjusting pillow (1) of the present invention can be configured with a plurality of auxiliary elastic members (42) having different elasticity as needed.

[0114] Meanwhile, referring again to FIGS. 10a and 10b, as described above, the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) have different elastic forces and driving points.

[0115] This driving unit (40) is arranged between the first pressure member (63) and the second pressure member (64), and the first pressure member (63) and the second pressure member (64) are arranged on the elasticity adjustment shaft (62) of the elasticity adjustment unit (60) to be described later.

[0116] At this time, the first pressure member (63) and the second pressure member (64) have at least one step, and the main elastic member (41) may be arranged between the end (63a) of the first pressure member (63) and the end (64a) of the second pressure member (64), and the auxiliary elastic member (42) may be arranged between the step (63b) of the first pressure member (63) and the step (64b) of the second pressure member (64).

[0117] The main elastic member (41) and the auxiliary elastic member (42) may be coil springs, and are arranged with springs of different thicknesses (R1, R2) and different lengths (L1, L2), and the number of coils wound is also configured differently. Accordingly, the main elastic member (41) and the auxiliary elastic member (42) have different elastic forces.

[0118] However, the main elastic member (41) and the auxiliary elastic member (42) have different elastic forces but provide elastic forces in the same direction to generate elastic driving force.

[0119] At this time, the main elastic member (41) is a spring with high elasticity, and provides elasticity to push the first pressure member (63) and the connecting block (53) between the end (63a) of the first pressure member (63) and the end (64a) of the second pressure member (64).

[0120] In addition, the auxiliary elastic member (42) is a spring with lower elasticity than the main elastic member (41), and provides elasticity to push the first pressure member (63) and the connecting block (53) between the step (63b) of the first pressure member (63) and the step (64b) of the second pressure member (64).

[0121] According to this arrangement, the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) have different elastic forces and driving points.

[0122] Meanwhile, the elastic adjustment shaft (62) may be provided with a main elastic member (41) and an auxiliary elastic member (42) between the first pressure member (63) and the second pressure member (64) as a single shaft.

[0123] Meanwhile, the elastic adjustment shafts (62) may be arranged in parallel and adjacent to each other, and each elastic adjustment shaft (62) may be provided with a main elastic member (41) and an auxiliary elastic member (42).

[0124] In addition, the elastic adjustment shaft (62) may be arranged on the same axis as the height adjustment shaft (52) to be described later, or may be arranged on a separate axis.

[0125]

[0126] Meanwhile, referring again to FIGS. 2 to 13, the variable portion (30) applied to the automatic height-adjusting pillow (1) according to one embodiment of the present invention has an “X” shape in which the first support (31) and the second support (32) are connected through a link portion (33).

[0127] Specifically, referring to Fig. 8, the first support (31) is configured to connect and support one side (right side) of the upper surface of the lower plate (20) and the other side (left side) of the lower surface of the upper plate (10).

[0128] And, the second support (32) is configured to connect and support the upper surface (left side) of the lower plate (20) and the lower surface (right side) of the upper plate (10).

[0129] At this time, the first support (31) and the second support (32) have an “X” shape as the intersecting central axis portions are connected through the link portion (33).

[0130] More specifically, the first support (31) is installed so as to be hinge-rotatable through the first-first hinge (34) while one side is fixedly positioned on one side (right side) of the upper surface of the lower plate (20), and the other side is installed so as to be hinge-rotatable through the first-second hinge (35) while the other side is positioned variably on the other side (left side) of the lower surface of the upper plate (10).

[0131] And, the second support (32) is installed so that it can pivot by hinge through the second-second hinge (36) while one side is fixed in position on one side (right side) of the lower surface of the upper plate (10), and the other side is installed so that it can pivot by hinge through the second-second hinge (37) while its position is variable on the other side (left side) of the upper surface of the lower plate (20).

[0132] Meanwhile, the upper plate (10) has a length in the left and right directions on the other side (left side) of the lower surface and includes an upper plate rail (13) that is integrally connected through a connecting member (4).

[0133] And, the lower plate (20) includes a lower plate rail (23) that has a length in the left and right directions on the upper surface (left side) and is integrally connected through a connecting member (4).

[0134] At this time, the first support (31) includes an upper guide block (14) that is integrally fixed with the first-second hinge (35), and the upper guide block (14) is coupled so as to be able to slide along the upper plate rail portion (13).

[0135] And, the second support (32) includes a lower guide block (24) that is integrally fixed to the second-second hinge (37), and the lower guide block (24) is coupled so as to be able to slide along the lower rail portion (23).

[0136] That is, the first support (31) and the second support (32) have a structure in which the height can be adjusted as the upper guide block (14) and the lower guide block (24) slide along the upper rail portion (13) and the lower rail portion (23).

[0137] Meanwhile, the variable portion (30) applied to the automatic height-adjusting pillow (1) according to one embodiment of the present invention is preferably configured to be positioned forward with an imaginary line dividing the front and the rear at the center.

[0138] Referring to Fig. 5, the user's head is connected to the body, so when sleeping using a pillow (1), the load is inevitably more concentrated toward the part that the body touches. Accordingly, even if the variable parts (30) are installed on both the front and rear sides and are made as sturdy as possible, the upper part (10) will inevitably tilt.

[0139] In other words, since less load is applied to the rear portion of the upper part (10), the rear portion becomes higher, and since more load is concentrated on the front portion of the upper part (10), the front portion becomes lower than the rear portion. In this case, the rear portion of the user's neck rises and the front portion falls, so the cervical vertebrae cannot maintain a "C"-shaped curve, making it impossible to maintain a correct posture.

[0140] However, since the automatic height-adjusting pillow (1) of the present invention is configured so that the variable portion (30) is positioned closer to the center of gravity of the user's head and tilted forward closer to the user's body, the variable portion (30) is positioned closer to the center of gravity of the user's head, and the inclination of the upper portion (10) is minimized. Accordingly, the cervical vertebrae can better maintain the "C"-shaped curve, and the user can sleep more comfortably without discomfort during sleep.

[0141]

[0142] Meanwhile, an automatic height-adjusting pillow (1) according to one embodiment of the present invention includes a height-adjusting unit (50) so that the user can set the height of the pillow to suit the user at the beginning of use according to the user's physical characteristics (size of the head and shoulders and weight of the head) when using the pillow, as described above.

[0143] And, it includes an elasticity control unit (60) that controls the elasticity of the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) to control the elastic driving force of the driving unit (40).

[0144] Preferably, the height adjustment part (50) and elastic adjustment part (60) have a structure in which the height or elastic driving force can be adjusted by rotating the connected adjustment shaft (52, 62) while the user holds and rotates the adjustment knob (51, 61) formed to protrude outwardly of the automatic height adjustment pillow (1).

[0145] It is preferable that the height adjustment part (50) and the elasticity adjustment part (60) be placed on the lower side of the upper part (10) of the pillow (1), or more generally, on the upper side of the pillow (1), so that the user can easily operate the height adjustment part (50) and the elasticity adjustment part (60) while lying down to sleep.

[0146] However, the arrangement of the height adjustment part (50) and the elastic adjustment part (60) is not limited to this, and it goes without saying that they may be arranged on the upper side of the lower part (20), or on the lower side of the pillow (1) as a whole, as needed.

[0147]

[0148] First, referring to FIG. 4 and FIG. 12, the height adjustment unit (50) includes, for example, a height adjustment knob (51) that allows a user to hold and rotate it in a grippable shape, and a height adjustment shaft (52) that is rotatably connected to the height adjustment knob (51) and has a length in the left and right directions.

[0149] In addition, the height adjustment unit (50) includes a connecting block (53) that changes position according to the rotation of the height adjustment shaft (52) and moves the variable unit (30) in a direction in which the height increases or decreases. This connecting block (53) may have a structure that is connected to one end of the variable unit (30) and can pull or push the variable unit (30).

[0150] Accordingly, the user can adjust the height of the variable part (30) to the desired height of the pillow simply by holding and rotating the height adjustment knob (51).

[0151] Meanwhile, this height adjustment part (50) is installed to be fixed to the lower surface of the upper part (10) or the upper surface of the lower part (20).

[0152] As a more specific example, the height adjustment unit (50) will be described again with reference to FIGS. 4 and 12 as follows. In the illustration, the height adjustment unit (50) is shown as being arranged on the lower surface of the upper plate (10), but it is not limited thereto and of course, it can be arranged on the upper surface of the lower plate (20).

[0153] In one embodiment, the height adjustment unit (50) may include a height adjustment knob (51), a height adjustment shaft (52), a connecting block (53), a restraint block (54), a connecting frame (55), a first support block (56), and a support pipe (57).

[0154] As described above, the height adjustment knob (51) has a shape that can be gripped by a user in a position that protrudes from the outside of the automatic height adjustment pillow (1). This height adjustment knob (51) may have a circular, oval, or polygonal shape, and of course, various shapes can be applied as long as the user can apply a force to grip and rotate it.

[0155] And, the height adjustment shaft (52) is positioned to have a length in the left and right directions inside the pillow (1), and has a structure in which it rotates when the user turns the height adjustment knob (51) in a bar shape that is integrally connected to the height adjustment knob (51).

[0156] Meanwhile, the height adjustment shaft (52) is supported in position by the first support block (56), and the first support block (56) is fixedly connected to the upper plate (10) or the lower plate (20) and the height adjustment shaft (52) is rotatably passed through the first support block (56).

[0157] Meanwhile, the end side of the height adjustment shaft (52) is screw-connected with the screw thread formed on the inner surface of the support tube (57).

[0158] This support pipe (57) is provided as an integral part with the connecting block (53), and as the height adjustment shaft (52) threadedly connected to the inner surface of the support pipe (57) rotates, the support pipe (57) and the connecting block (53) can move linearly in a direction of being pulled or pushed.

[0159] Meanwhile, it goes without saying that the support member (57) may further include a catch (not shown) as needed to prevent the height adjustment shaft (52) from falling off or coming off.

[0160] Meanwhile, on one side of the upper rail section (13) or the lower rail section (23), a restraining block (54) is provided that is slidably connected to one side of the upper rail section (13) or the lower rail section (23) separately from the upper guide block (14) and the lower guide block (24).

[0161] At this time, the restraint block (54) is integrally connected to the upper guide block (14) or the lower guide block (24) through the connecting frame (55). In addition, the connecting frame (55) has a structure in which it is integrally connected to the connecting block (53).

[0162] In Fig. 12, the height adjustment part (50) is structured to be placed on the lower surface of the upper part (10), and when the user rotates the height adjustment knob (51), the height adjustment shaft (52) is supported by the first support block (56) and rotates along the internal screw thread of the support pipe part (57).

[0163] At this time, the support member (57) moves in a linear direction toward or away from the height adjustment knob (51), and the connecting block (53), connecting frame (55), restraining block (54), and upper guide block (14) integrally connected to the support member (57) also move in a linear direction together.

[0164] At this time, the upper guide block (14) is structured to be connected to the first support (31) through the first-second hinge (35, Fig. 8), and as the upper guide block (14) moves along the upper rail portion (13), the first support (31) also moves variably in the direction of increasing height or decreasing height, and as a result, the height of the variable portion (30) including the first support (31) can be variably changed.

[0165] Accordingly, the user can set the height of the automatic height-adjusting pillow (1) according to the present invention to a height that suits him / her at the beginning of use.

[0166]

[0167] Meanwhile, referring to FIG. 4 and FIG. 13, the elastic control unit (60) can control the elastic driving force of the driving unit (40) disposed between the first pressing member (63) and the second pressing member (64) according to the user's selection.

[0168] To this end, the elasticity adjustment unit (60) includes an elasticity adjustment knob (61) that allows the user to hold and rotate it in a grippable shape, and an elasticity adjustment shaft (62) that is rotatably connected to the elasticity adjustment knob (61) and has a length in the left and right directions.

[0169] At this time, the elastic adjustment shaft (62) is provided to penetrate the first pressing member (63) and the second pressing member (64) in which the driving member (40) is arranged at a gap between them.

[0170] When the user rotates the elasticity adjustment knob (61), the elasticity adjustment shaft (62) rotates, and the positions of the first pressure member (63) and the second pressure member (64) are adjusted in a direction in which the gap between them increases or decreases, and accordingly, the elastic driving force of the driving unit (40) can be adjusted.

[0171] Meanwhile, this elastic adjustment part (60) can be installed fixedly on the lower surface of the upper part (10) or the upper surface of the lower part (20) like the height adjustment part (50).

[0172] As a more specific example, the elasticity control unit (60) will be described again with reference to FIGS. 4 and 12 as follows. In the illustration, the elasticity control unit (60) is shown as being arranged on the lower surface of the upper plate (10), but it is not limited thereto and of course, it can be arranged on the upper surface of the lower plate (20).

[0173] In one embodiment, the elasticity adjustment unit (60) may include an elasticity adjustment knob (61), an elasticity adjustment shaft (62), a first pressure member (63), a second pressure member (64), and a second support block (65).

[0174] As described above, the elastic adjustment knob (61) has a shape that can be gripped by the user in a position that protrudes from the outside of the automatic height adjustment pillow (1). This elastic adjustment knob (61) may have a circular, oval, or polygonal shape, and of course, various shapes can be applied as long as the user can apply a force that can be gripped and rotated.

[0175] In addition, the elastic adjustment shaft (62) is positioned to have a length in the left and right directions inside the pillow (1), and has a structure in which it rotates when the user rotates the elastic adjustment knob (61) in a bar shape that is integrally connected to the elastic adjustment knob (61).

[0176] Meanwhile, the elastic adjustment shaft (62) is supported in position by a second support block (65), and the second support block (65) is fixedly connected to the upper plate (10) or the lower plate (20) and the elastic adjustment shaft (62) is rotatably passed through the second support block (65).

[0177] At this time, the second support block (65) may have a structure in which screw threads are formed on the inner surface. Accordingly, the second support block (65) and the elastic adjustment shaft (62) may have a structure in which the screw threads are connected, and the elastic adjustment shaft (62) may have a structure in which it moves linearly along the screw threads while rotating.

[0178] Meanwhile, the elastic adjustment shaft (62) can be arranged on the same axis as the height adjustment shaft (52) of the height adjustment unit (50) described above. At this time, the elastic adjustment shaft (62) is arranged to be rotatable while penetrating the connecting block (53).

[0179] And, the first pressure member (63) is rotatably penetrated by an elastic adjustment shaft (62) and is fixed integrally with the connecting block (53).

[0180] In addition, the second pressure member (64) has a structure in which it is integrally fixed to the elastic adjustment shaft (62). At this time, the second pressure member (64) has a structure in which it is arranged on the outer surface of the elastic adjustment shaft (62) with a gap therebetween and the first pressure member (63), and the driving unit (40) is arranged on the gap therebetween.

[0181] Meanwhile, the elastic adjustment shaft (62) can be arranged on the same axis as the height adjustment shaft (52) and has a structure that can move linearly along the internal space of the height adjustment shaft (52).

[0182] According to this structure, the elastic adjustment part (60) applied to the automatic height adjustment pillow (1) according to one embodiment of the present invention is adjusted so that the second pressure member (64) moves toward the first pressure member (63) and the gap between them becomes wider or narrower as the elastic adjustment shaft (62) rotates and moves in a straight line.

[0183] Accordingly, the main elastic member (41) or auxiliary elastic member (42) constituting the driving member (40) arranged between the first pressure member (63) and the second pressure member (64) can have its elasticity adjusted according to changes in the gap between the first pressure member (63) and the second pressure member (64).

[0184] Meanwhile, the elastic adjustment shaft (62) may be arranged on the same axis as the height adjustment shaft (52) of the height adjustment unit (50) as described above. At this time, the elastic adjustment shaft (62) may have a structure that moves along an internal space formed at the end of the height adjustment shaft (52).

[0185]

[0186] Referring again to FIGS. 2 to 13, the state of use in which the height of the automatic height-adjusting pillow (1) according to one embodiment of the present invention is adjusted according to a change in the user's sleeping posture is as follows.

[0187] As described above, the automatic height-adjusting pillow (1) according to one embodiment of the present invention is configured to automatically adjust the height of the pillow so that the user's cervical spine can maintain a correct posture according to a change in the user's posture while sleeping, that is, a change in posture between lying down in a straight posture (front posture) and looking at the sky and lying on the side (side posture).

[0188] Fig. 2 shows a state in which the initial height can be adjusted to fit the user's body shape using the height adjustment unit (50).

[0189] At this time, when the user lies down with the pillow (1) in a frontal position for sleeping, the height of the automatic height-adjusting pillow (1) is lowered as shown in Fig. 5 due to the load of the user's head.

[0190] At this time, the elastic driving force of the driving unit (40) pushes the variable unit (30) in the direction of increasing height to increase the height, but the elastic driving force is less than the force applied by the load of the head, so the height of the pillow (1) is lowered.

[0191] Specifically, referring to FIGS. 3 to 6 and FIG. 8, when the state of FIG. 5 is such that the user's head load in a frontal posture is applied to the upper part (10), the upper part (10) is pressed toward the lower part (20).

[0192] At this time, the upper guide block (14) slides to the outside of the pillow (1) along the upper rail portion (13), and the other side of the first support (31) hinge-connected to the upper guide block (14) through the first-second hinge (35) moves in the direction in which the height of the variable portion (30) is lowered. Then, one side of the first support (31) is hinge-rotated through the first-first hinge (34), and the first support (31) is lowered in height as shown in Fig. 6.

[0193] At this time, the second support (32) is also moved downwards by pivoting a hinge through the second-first hinge (36) with one side fixed to the lower surface of the upper part (10) through a fixing block (36a), and the other side of the second support (32) is connected to the lower guide block (24) through the second-second hinge (37), and moves in a direction in which the height decreases as the lower guide block (24) slides to the outside of the pillow (1) along the lower rail part (23).

[0194] Accordingly, the overall height of the variable part (30) is lowered, and the automatic height adjustment pillow (1) is lowered in a state similar to that in FIG. 6 from the state in FIG. 5.

[0195] Meanwhile, the upper guide block (14) is formed as an integral part with the restraint block (54) and the connecting block (53) through the connecting frame (55) as described above, and as the upper guide block (14) slides along the upper rail portion (13) to the outside of the pillow (1), the restraint block (54) and the connecting block (53) also move in the same direction as the upper guide block (14).

[0196] At this time, the connecting block (53) is integrally connected to the first pressure member (63) as shown in FIGS. 10a and 10b, so that the first pressure member (63) moves toward the second pressure member (64), and the gap between the first pressure member (63) and the second pressure member (64) narrows. Accordingly, the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) arranged between the first pressure member (63) and the second pressure member (64) are in a compressed state.

[0197] At this time, among the elastic members constituting the driving unit (40), the main elastic member (41) that first comes into contact with the pressure members (63, 64) by the ends (63a, 64a) is first pressured and supports the load of the head. However, soon, as shown in Fig. 1a, the main elastic member (41) alone cannot withstand the pressure of the load. At this time, the auxiliary elastic member (42) that receives the force of the pressure members (63, 64) by the ends (63b, 64b) operates in succession to the main elastic member (41), and the combined force of the main elastic member (41) and the auxiliary elastic member (42) enables the pressure according to the load of the head to be flexibly supported (see Fig. 11).

[0198] At this time, the driving unit (40) continues to provide elastic driving force in the direction of pushing the first pressure member (63).

[0199]

[0200] Next, when the user changes his / her posture from the front posture of Fig. 5 to the side posture of Fig. 7 while sleeping, the load on the head pressing on the upper part (10) is reduced.

[0201] At this time, as the compressed state of the main elastic member (41) and the auxiliary elastic member (42) is released, the height of the upper part (10) increases due to the combined elastic driving force of the main elastic member (41) and the auxiliary elastic member (42). At this time, when the height of the upper part (10) becomes a certain height or higher, the operation (provision of elastic force) of the auxiliary elastic member (42) arranged in the gap (L2, FIG. 10b) between the ends (63a, 64a) of the pressing members (63, 64) and the gaps (63b, 64b) is stopped according to the difference in the gap (L1, L2, FIG. 10b) between the gaps (63b, 64b), and the upper part (10) is lifted only by the force (elastic force) according to the operation of the main elastic member (41). Accordingly, the pillow (1) of the present invention prevents the shock of the user's head being lifted due to excessive elastic driving force, thereby enabling flexible pillow height adjustment.

[0202] In this way, the automatic height-adjusting pillow (1) of the present invention is automatically adjusted to a height at which the user's cervical spine becomes horizontal.

[0203] As shown in FIG. 11, the automatic height-adjusting pillow (1) according to one embodiment of the present invention, through the above-described process, has a curve (①) of the load applied to the height-adjusting pillow (1) by the head load according to the change in the user's sleeping posture and a curve (②) of the driving elastic force supported by the driving unit (40) that are quite close to each other.

[0204] Meanwhile, as the first pressure member (63) is pushed out by the elastic driving force, the connecting block (53) integrally connected to the first pressure member (63) is also pushed out.

[0205] As described above, the connecting block (53) is formed as an integral part with the restraining block (54), the connecting block (53) and the upper guide block (14) through the connecting frame (55).

[0206] Accordingly, the restraint block (54) and the upper guide block (14) slide along the upper rail portion (13) in the same direction as the first pressure member (63).

[0207] In other words, the upper guide block (14) and the restraint block (54) slide along the upper rail portion (13) toward the inside of the pillow (1), and the other side of the first support (31) hingedly connected to the upper guide block (14) through the first-second hinge (35) moves in the direction in which the height of the variable portion (30) increases. Then, one side of the first support (31) is hinge-rotated through the first-first hinge (34), and the first support (31) increases in height as shown in FIGS. 8 and 9.

[0208] At this time, the second support (32) is also fixed to the lower surface of the upper part (10) through a fixing block (36a) and moves upwards while pivoting on a hinge through the second-first hinge (36), and the other side of the second support (32) is connected to the lower guide block (24) through the second-second hinge (37), and as the one side moves upwards, the second lower guide block (24) slides along the lower rail part (23) and moves toward the inside of the pillow (1).

[0209] Accordingly, the overall height of the variable part (30) increases from the state of FIG. 5, and the automatic height-adjusting pillow (1) has a height that allows the user's cervical spine to remain horizontal and comfortable, as shown in FIG. 7.

[0210] The driving unit (40) always provides elastic driving force to the variable unit (30) in the direction in which the height of the variable unit (30) increases.

[0211] Accordingly, in the frontal posture, the load on the head is greater than the elastic driving force of the driving unit (40), so the head is pressed and the height of the pillow is lowered. In the side posture, as the load on the head is reduced, the elastic driving force of the driving unit (40) overcomes the load on the head, and as the height of the variable unit (30) increases, the height of the pillow increases.

[0212] In addition, the driving unit (40) is composed of a plurality of elastic members including a main elastic member (41) and at least one auxiliary elastic member (42), and the main elastic member (41) and the auxiliary elastic member (42) provide different elastic forces and driving points, so that the elastic driving force provided from the driving unit (40) to the variable member (30) can flexibly provide the force required to support the change in the user's head load when the user's posture changes during sleep.

[0213]

[0214] As described above, the automatic height-adjusting pillow (1) according to one embodiment of the present invention changes the load applied to the upper part (10) when the user changes his / her posture while sleeping and the height of the head changes, and accordingly, the height of the variable part (30) supporting the upper part (10) changes, so that the user's cervical spine can maintain the correct shape even while sleeping.

[0215] In addition, the driving unit (40) that provides elastic driving force to the variable unit (30) is composed of a main elastic member (41) and an auxiliary elastic member (42) that have different elastic forces and driving points, and can flexibly respond to changes in the load applied to the upper part (10) according to changes in the user's posture while sleeping, thereby providing an appropriate elastic driving force.

[0216] In addition, the height of the pillow (1) required can be stably changed without separate operation according to the change in load due to change in posture during sleeping, so that the user's neck can maintain the correct shape.

[0217] In addition, the height of the pillow can be adjusted to suit the user's body type when first used through the height adjustment part (50), so that each user can select a pillow height that suits their sleeping habits.

[0218] In addition, the elasticity of the main elastic member (41) and the auxiliary elastic member (42) constituting the driving unit (40) can be adjusted through the elasticity control unit (60), so that not only can an elastic driving force be provided that is suitable for the head weight of each user, but also the elastic driving force can be stably provided through readjustment of the elastic driving force over time.
