Description

FIELD OF THE INVENTION

The present invention relates to the technical field of mattress, more particularly, to a mattress for bed frame with bow structure.

BACKGROUND OF THE INVENTION

In daily life, people often use various portable beds for comfort when camping outdoors or taking a lunch break in the company office. The normal portable beds generally consist of frames and mattress fixed on the frame. The mattress are usually made of a single piece of fabric. If the mattress is too thin, it is difficult to support users with high body weight. If the mattress is too thick, it is not very breathable, which can easily cause sweat on the user's back and affect the user experience.

Chinese Utility Model CN201617494U discloses a type of portable bed, which mainly includes a bed frame, a bed board and a few of bed legs. The bed frame is composed of several shelves detachably connected through pins, and the bed board is composed of several straps fixed on the bed frame. The shelves is also detachably connected with arc supporting rods in the same direction as the straps. The shelves are detachably connected with the bed legs through the pins. Although the type of portable bed are convenient and breathable, it still has supporting deficiencies. If the straps are harder, the comfortability will poor, and if the straps are too soft, it will difficult to support the user's body. What's more, there is no connection structure between the adjacent straps, when users step on them, the pressure per unit region is relatively high and cannot be shared so that the strips are prone to breakage, and there is also a risk of foot sprains caused by users stepping on them empty. Therefore, it is necessary to improve the prior art to solve the above deficiencies,

The current mattress are generally hard mattress that can not be deformed, as shown in FIG. 1, when user lies on it, in the normal body curve of the human body, the curves of the buttocks and that of the back protrude from the back waist, which often causes the back waist to be suspended and unable to be supported, for a long time, this can lead to the waist diseases.

The current mattress is also made of latex, as shown in FIG. 2. Latex is prone to adaptive deformation according to the human body. However, latex mattresses are too soft, which can cause the human body to sink and cause the spine to bend, which is not conducive to human health. In addition, latex mattresses have many holes, which are easy to accumulate dust, insect eggs, etc. They are not easy to clean and are not breathable.

Therefor, it is urgent to develop a new mattress to overcome the deficiencies of the prior art.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a mattress for bed frame with bow structure, aiming to solve the mattress in the prior art is too hard or too soft. Which can not support the user's body better.

In order to achieve the above object, the present invention provide a mattress for bed frame with bow structure, which includes fixed seat and multiple of arc-shaped elastic rods, the mattress is formed by staggered connection of horizontally arranged weft lines and longitudinally arranged warp lines, and the weft lines are unevenly distributed in high-density regions and low-density regions. The multiple of arc-shaped elastic rods are sequentially installed side by side on the fixed seat and in the same direction as the weft lines. The free ends of each of the arc-shaped elastic rods are respectively directly or indirectly connected on the opposite edges of the mattress to tension and set up the mattress above the arc-shaped elastic rods.

Each of the high-density regions is composed of at least two of the weft lines side by side, each of the low-density regions is blank regions, or is composed of at least one of the weft lines and blank regions on both sides thereof, or the low density region is composed of several weft lines and the blank regions on both sides of each of the weft lines.

The diameter of each of the weft lines is 0.04-2 mm, the width of each of the blank regions is 0.2-2 mm; the diameter of each of the weft lines is 2-100 times of that of each of the warp lines.

Preferably, the weft lines and the warp lines are both made of Teslin.

Preferably, the widths of each of the high-density regions is equal or unequal to each other, while the width of the low-density regions is equal or unequal to each other.

The warp lines distributes evenly or unevenly, the distance of the adjacent warp lines is 0.2-5 mm. The adjacent warp lines pass above or under each of the weft line respectively

Both edges of the mattress are sewn with reinforcement lines.

The fixed seat includes two side rods. The free ends of all of the arc-shaped elastic rods are fixed on the side rods respectively, the opposite edges of the mattress are connected with the two side rods respectively.

Each of the edges wounds around one of the side rods and passes through joint points of the free ends and the side rods.

Each of the edges is folded to form a double-layer structure. The double-layer structure wounds one of the side rods and passes through the joint points of the free ends and the side rod. The double-layer structure is provided with a limiting hole above the arc-shaped elastic rods, the inserting rod is inserted the limiting hole and against the arc-shaped elastic rods across one side of the double-layer structure, thereby fixing the side edge.

The above one or more technical solutions in the mattress for bed frame with bow structure provided by the embodiments in the present invention have at least one of the following technical effects:

The mattress for bed frame with bow structure in the present invention is set up the bed frame with bow structure composed of multiple of the arc-shaped elastic rods, when a user sits or lies on the mattress, the region of the mattress directly suffering the pressure is depressed downwards and deformed, the amplitude of the depression in this region is related to the magnitude of the pressure. The greater the pressure, the greater the depression amplitude, and the smaller the pressure, the smaller the depression amplitude. In addition, the deformation is defined by the body shape of the user, the deformation curve matches the contact body shape of the user.

In the present invention, the warp lines are arranged in high-density regions and low-density regions unevenly, that is in the low-density regions, the number of the warp lines is reduced, thereby in some degree, reducing the interfere effect caused by the connection of the wrap lines and the weft lines, and reducing the deforming rang caused by interference in other regions connected to the region of the mattress directly suffering the weight. When the user sleeps on the mattress, the user's leg, buttocks, waist, back will apply pressure corresponding to their weight to the regions of the mattress directly contacting, resulting in corresponding degree of depressed deformation. At the same time, due to the small interfere effect of these stressed regions and the other regions, the deformation degree of each of the stressed regions is basically adapted to the pressure it is suffered. When the user lies on his back on a mattress, in the normal body curve, the buttocks and the back protrude from the waist, and the weight of these two parts is greater than the waist, causing the region of the mattress supporting the buttocks and the back to deform and depress significantly under pressure, so that the region corresponding to the waist can just fit tightly the waist and support it, thereby avoiding the waist from hanging in the air. When the user's sleeping position changes, for example, from lying on the user's back to lying on the user's side, the regions of the user's body contacting the mattress are changed, resulting in that the mattress is changed in corresponding deformation to adapt to the user's body shape.

The low-density regions has blank regions, which increasing the the ventilation and the breathability of the mattress and can timely remove sweat and odors.

The mattress is over the arc-shaped elastic rods in the bed frame with bow structure, can adapt to the weight and the body of the user and deform accordingly, thereby providing elastic support for the user's body, better meeting the user's usage needs, greatly improving comfort, and preventing body diseases such as lumbar spondylosis caused by poor sleeping posture.

The arc-shaped elastic rods connects with the mattress and tension it, when the pressure is applied to the mattress, the mattress is deformed and pulls the arc-shaped elastic rods to deform, and the arc-shaped elastic rods store elastic potential energy. When the pressure is released, the arc-shaped elastic rod releases the elastic potential energy, which in turn tightens the mattress, allowing it to maintain a tension state for a long time without collapsing, extending the service life of the mattress.

In the mattress for bed frame with bow structure in the present invention, the mattress is hung up in the air, which can not breed bacteria, mites, etc., making it easy to clean and maintain.

In one embodiment in the present invention, as shown in FIG. 4-7, the mattress 100 for bed frame with bow structure, which includes fixed seat 300 and multiple of arc-shaped elastic rods 200, the mattress 100 is formed by staggered connection of horizontally arranged weft lines 101 and longitudinally arranged warp lines 102, and the weft lines 101 are unevenly distributed in high-density regions 100a and low-density regions 100b. The multiple of arc-shaped elastic rods 200 are sequentially installed side by side on the fixed seat 300 in the same direction as the weft lines 101. The free ends of each of the arc-shaped elastic rods 200 are directly or indirectly connected with the edge of the mattress 100 to tension and set up the mattress 100 above the arc-shaped elastic rods 200.

When a user sleeps or sits on the mattress 100, the mattress 100 bears the weight of the user to deform and pull directly or indirectly the free ends 201 of each of the arc-shaped elastic rods 200, causing the arc-shaped elastic rods 200 to deform and store elastic potential energy, and the two free ends 201 to be relatively closed, so that the mattress 100 to deform from a flat state into a downward depression state. The region of the mattress 100 directly bearing the weight of the user, that is directly contacting with the body of the user, is concave downward, the weft lines 101 and the warp lines 102 passing through the region pull the weft lines 101 and warp lines 102 in other regions and connected thereto, causing interference between each other, resulting in corresponding concave deformation in the other regions as well. The concave range of the region of the matress100 directly bearing the weight is related to the magnitude of the weight borne. The greater the weight borne, the greater the concave range. The smaller the weight borne, the smaller the concave range. The concave range of the other regions, that have interference effects with the region of the matress100 directly bearing the weight, is also the same. In addition, the deformation of the mattress 100 is also defined by the body shape of the user, and its concave curve matches the body shape of the user.

Referring to FIG. 5, in the invention, the warp lines 101 are arranged in high-density regions 100a and low-density regions 100b unevenly, that is in the low-density regions, the number of the warp lines is reduced, thereby in some degree reducing the interfere effect, and reducing the concave rang caused by interference in the other regions connected to the region of the mattress directly bearing the weight. When the user sleeps on the mattress, the user's leg, buttocks, waist, back will apply pressure corresponding to their weight to the regions of the mattress directly contacting, resulting in corresponding degree of concave deformation. At the same time, due to the small interfere effect of these stressed regions and the other regions, the concave rang of each of the stressed regions is basically adapted to the pressure it is suffered.

Referring to FIG. 3, when user's lies on his back on the mattress 100, in the normal body curve, the buttocks and the back protrude from the waist, and the weight of these two parts is greater than the waist, causing the region of the mattress supporting the buttocks and the back to deform and depress significantly under pressure, so that the region corresponding to the waist can just fit tightly the waist and support it, thereby avoiding the waist from hanging in the air. When the user's sleeping position changes, for example, from lying on the user's back to lying on the user's side, the regions of the user's body contacting the mattress are changed, resulting in that the mattress is changed in corresponding deformation to adapt to the user's body shape, providing better supporting to the user's body.

The mattress 100 can adapt to the weight and the body of the user and deform accordingly, thereby providing elastic support for the user's body, greatly improving comfort, and preventing body diseases such as lumbar spondylosis caused by poor sleeping posture.

Referring to FIG. 5, each of the high-density regions 100a is composed of at least two of the weft lines 101 side by side. The number of the warp lines 101 of each of the high-density regions is preferably 3-10. In the high-density regions 100a, the adjacent warp lines 101 are side by side, when bearing weight, they interfere with each other and share weight, thereby reducing the pressure borne by each weft line.

It should be understood that the interfere of the regions of the mattress 100 directly contacting with the user's body and the other regions of the mattress 100 not contacting with the user's body is realized by the weft lines and the warp lines passing each of the regions and swagged connection. For reducing the interfere, the low-density regions may be blank regions. On this occasions, both sides of the high-density regions are blank regions. When the high density regions bears weight to deform, the weft lines 101 in this high density regions interfere the weft lines 101 and the warp lines 102 connected with them but not bearing weight in the other regions, causing them to deform. The black regions 102a have no the weft lines 101, it can not interfere the other regions by the swagged connection of the weft lines 101 and the warp lines 102, and the number of the warp lines 102 connected the weft lines 101 in this regions is less, although the interfere effect can be caused by the swagged connection of the warp lines 102 passing through this high-density regions and the weft lines 101 and the warp lines 102 passing the other high-density regions, the interfere effect is greatly reduced, thereby each of the regions of the mattress 100 can adapt relatively independently to the weight and the shape of the user it contacted and deform. It should be understood that the low-density regions may be composed of at least one of the weft lines and its blank regions on both sides, or the low density region is composed of several weft lines and the blank regions on both sides of each of the weft line. In addition, since the number of the weft lines 101 in the high-density regions is relatively larger than that of the weft lines 101 in the low-density regions, the knitting density of the high-density region 100a is higher than that of the low-density region 100b, the high-density regions 100a is stronger, and can improve the supporting force of the mattress 100, thereby providing a wider range of application. The low density region 100b, however, has blank regions. Compared with the high-density region 100a, the low density region 100b has a low weaving density, is easy to stretch and deform, has a better air permeability, can improve the self-adaptive performance of the mattress 100, better fits the user's body, can also improve the overall air permeability of the mattress, and improves the comfort of the user.

The diameter of each of the weft lines 101 is 0.04-2 mm, the width of each of the blank regions is 0.2-2 mm; the diameter of each of the weft lines 101 is 2-100 times of that of each of the warp lines 102. The weft lines and the warp lines are both made of Teslin. The diameter of the weft lines 101 is larger than that of the warp lines 102, the two has the same material, thereby that the warp line 102 has better deformation resistance than weft lines 101, while the weft lines 101 are relatively easily to deform. When the user sleeps on the mattress, the mattress bears the weight of the user and is easy to be deformed and depressed along the direction of the warp lines 102, however it is relatively difficult to be deformed and depressed along the direction of the weft lines 101, although the weft lines 101 are depressed together with the warp lines 102, thereby providing the user with a good support.

The widths of the high-density regions 110a are equal or unequal, while the widths of the low-density regions 100b are equal or unequal. It should be understood that the widths of the high-density regions 110a and that of the low-density regions 100b can be arranged according to the weight of the body parts of the user, for example. the waist is more weight than the leg, therefor, the high-density regions 110a corresponding to the waist should be wider, the low-density regions 110b corresponding to the waist should be more narrow.

It should be understood that the wider the high densityregions100 are, the worse the self-adaptive effect of the mattress is, the more difficult it is to deform according to the shape of the user's body, and the stiffer the mattress is perceived by the user. The more the low density regions 100b are, the easier the mattress is deformed, the better the self-adaptation is, and the softer the mattress is. The widths of the high density regions 100a and the low sealing regions 102 may also be adjusted according to requirements during production, so as to adjust the self-adaptation effect and the softness of the mattress 100.

Preferably, the weft lines 101 and the warp lines 102 are both made of Teslin.

The warp lines 102 distributes evenly or unevenly, the adjacent warp lines 102 pass above or under each of the weft line 101 respectively. The distance of the adjacent warp lines is 0.2-5 mm. The distance of the adjacent warp lines is greater than the distance of the adjacent weft threads, especially greater than the distance of the adjacent weft threads in the high-density regions. The sparse arrangement of the warp lines 102 also aims to increase the deformation degree of the mattress in the direction of the warp line, so that when the user sleeps on the mattress, the mattress can adapt to the user's body to be deformed, and the deformation degree in direction of the warp lines is greater 4 than that in the direction of the weft lines, especially that in the high-density regions, thereby better supporting the user's body.

Both side edges of the mattress are sewn with reinforcement lines. The reinforcement lines avoids the weft lines 101 from being spread out after the warp lines 102 are broken so that the mattress is more durable.

Referring to FIG. 6 and FIG. 7, the fixed seat 300 includes two side rods 301. The free ends 201 of all of the arc-shaped elastic rods 200 are fixed on the side rods 301 respectively, the opposite side edges 103 of the mattress 100 are connected with the two side rods 301 respectively.
