Detailed Description

In order to make the object, technical solution and technical effect of the present invention more apparent, the present invention will be further described with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, the degree of softness and hardness of the bed is reflected in the degree of ease of deformation of the flexible support member and the magnitude of downward movement under pressure, as described below. When the mattress is produced and molded, the deformation difficulty is constant. Therefore, the softness and hardness of the mattress can be adjusted by adjusting the amplitude of the downward movement of the flexible bearing element under the pressure.

Referring to fig. 1 and 2, the adaptive soft and hard adjustable mattress comprises a bed frame 10, a plurality of arc-shaped elastic rods 20 and a flexible bearing piece 30. The plurality of arc-shaped elastic rods 20 are suspended side by side on the bed frame 10, and the two opposite sides 31 of the flexible bearing member 30 are mounted at the two ends 21 of the arc-shaped elastic rods 20, tensioned and mounted on the arc-shaped elastic rods 20. It will be appreciated that the flexible carrier 30 must overcome its resistance to bending in order to pull the curved resilient rods 20 to deform.

The adaptive adjustable-softness mattress further comprises a softness adjusting mechanism 100 which is arranged below the arc-shaped elastic rod 20 and supports the arc-shaped elastic rod 20 upwards; the flexible bearing member 30 is deformed by the downward pressure and presses the arc-shaped elastic rods 20 to move downward, and the hardness and softness adjusting mechanism 100 controls the downward movement amplitude of the arc-shaped elastic rods 20, so as to control the hardness and softness of the mattress.

When a person sleeps on the flexible bearing member 30, the flexible bearing member 30 bears the weight of the human body and deforms by sinking downwards. Different parts of the human body have different weights, for example, the weight of the chest, the waist and the abdomen, the hip and the leg, and different pressures are respectively applied to the flexible bearing parts 30 attached to the parts, so that the corresponding flexible bearing parts 30 generate depressions with different amplitudes to adapt to the physical curve of the human body. Meanwhile, the flexible supporting part 30 applies downward pressure to the suspended arc-shaped elastic part 20, so that the arc-shaped elastic part moves downward with different amplitudes and drives the flexible supporting part 30 to move downward. The flexible supporting member 30 further applies a pulling force to the two end portions 21 of each of the arc-shaped elastic rods 20 connected to the two side edges 31 thereof, and when the pulling force exceeds the bending resistance of the arc-shaped elastic rods 20, the two end portions are relatively closed, so that each of the arc-shaped elastic rods 20 is deformed in different ranges, thereby achieving the effect of self-adapting to the physical and physical curve of the human body. Different persons have different requirements on the softness and hardness of the mattress, i.e. different requirements on the ease and extent of deformation of the flexible load bearing member 30. The hardness adjusting mechanism 100 adjusts the degree of difficulty and the amplitude of the flexible supporting member 30 moving downward by adjusting the degree of difficulty and the amplitude of the arc-shaped elastic rod 20 moving downward under pressure, that is, the hardness of the mattress.

Two soft and hard adjusting mechanisms 100 are symmetrically arranged below the arc-shaped elastic rod 20; the hardness adjusting mechanism 100 comprises a driving element 110 and a pushing element 120, the driving element 110 pushes the pushing element 120 to rotate, and the pushing element 120 contacts and pushes up the arc-shaped elastic rod 20, so as to adjust the difficulty and the amplitude of downward movement of the arc-shaped elastic rod 20 under the stress, i.e. adjust the hardness of the mattress.

The soft and hard adjusting mechanisms 100 are respectively arranged below the two end portions 21 of the arc-shaped elastic rod 20. The hardness adjusting mechanism 100 includes a pair of mounting seats 130, the pair of mounting seats 130 is fixedly connected to two ends of the bed frame 10, and each mounting seat 130 is provided with a pivot shaft 124. The pushing assembly 120 includes a rotating rod 121, a pushing rod 122 and two pivoting arms 123, and each pivoting arm 123 is mounted on and rotatable about one of the pivoting shafts 124. Two ends of the rotating rod 121 are respectively and fixedly mounted at the bottom ends of the two pivoting arms 123, and two ends of the pushing rod 122 are respectively and fixedly mounted at the top ends of the two pivoting arms 123 and are located below the end portion 21 of the arc-shaped elastic rod 20. The driving member 110 is connected to the rotating rod 121. The driving member 110 pushes the rotating rod 121 to drive the pivoting arm 123 to rotate around the pivoting shaft 124, so as to drive the pushing rod 122 to rotate, contact and push up the arc-shaped elastic rod 20. Assuming that the flexible carrier 30 is pressed downward, and the downward pressure applied to the arc-shaped elastic rod 20 is F, and the force of the pushing rod 122 pushing the arc-shaped elastic rod 20 upward is F1, when F > F1, the arc-shaped elastic rod 20 can move downward and drive the flexible carrier 30 to move downward. When F = F1, the arc-shaped elastic rod 20 cannot move downwards, and when F < F1, the arc-shaped elastic rod 20 will move upwards and drive the flexible bearing member 30 to move upwards. Obviously, when F1=0, that is, the pushing rod 122 does not contact the curved elastic rod 20 and does not apply an upward force thereto, the curved elastic rod 20 is moved downward most easily by the force F and the magnitude of the downward movement is the largest, and correspondingly, the mattress is the softest. As F1 increases, the curved spring rods 20 are more and more difficult to move downward under pressure, and the mattress is correspondingly stiffer.

Preferably, the hardness adjusting mechanism 100 further comprises a lever assembly 140, and the lever assembly 140 alone or in combination with the pushing rod 122 adjusts the difficulty and magnitude of the downward movement of the curved resilient rod 20 under pressure. The lever assembly 140 includes a plurality of sleeving parts 141, a plurality of levers 142 and a supporting rod 143, each sleeving part 141 is mounted on one of the arc-shaped elastic rods 20 and is located between the middle of the arc-shaped elastic rod 20 and the pushing rod 122, one end of each lever 142 is fixedly connected to one sleeving part 141, and two ends of the supporting rod 143 are respectively and fixedly mounted in the middle of the pivoting arm 123 and are located below the lever 142 to contact with or approach to the lever 142.

As shown in fig. 3, in the initial position, the pivot arm 123 is substantially perpendicular to the horizontal plane 152 of the mattress, and the support bar 143 contacts or is closer to the lower surface of the lever 142, and there is a distance between the push rod 122 and the lower surface of the curved elastic bar 20. When a human body lies on the flexible bearing member 30, the flexible bearing member 30 is pressed down by the weight of each part of the human body, and the curved elastic rod 20 connected thereto is pressed down, assuming that the force of pressing down the curved elastic rod 20 is F. At this time, each of the arc-shaped elastic rods 20 is pushed downward and drives the lever 142 to move downward through the sleeve 141 thereon, so that the supporting rod 143 supports the other end of the lever 142, and the reaction force exerted by the supporting rod 143 on the arc-shaped elastic rods 142 through the lever 142 and the sleeve is assumed to be F2, where F2 is extremely small or equal to 0 and can be basically ignored. At this time, the curved elastic rod 142 is most easily moved downward by a force, and the magnitude of the downward movement is also the largest, and the mattress is the softest.

As shown in fig. 4, the driving member 110 is actuated to push the rotating rod 121 to rotate, so as to drive the pivoting arm 123 to rotate around the pivoting shaft, thereby driving the pushing rod 122 and the supporting rod 143 to rotate, and the supporting rod 143 moves along the lever 142 toward the socket. While the push rod 122 has not yet contacted the curved elastic rod 20. In the state shown in fig. 4, when a human body lies on the flexible bearing member 30, the flexible bearing member 30 is pressed down by the weight of each part of the human body and the arc-shaped elastic rod 20 is pressed down, and the support rod applies an upward supporting force F2 to the arc-shaped elastic member through the lever and the socket member to increase, so as to offset a part of the downward pressure F. When F is the same, the degree of difficulty and magnitude of the downward movement of the curved resilient bars 142 is reduced and the mattress is relatively stiff, as compared to the case illustrated in fig. 3.

As shown in fig. 5, the driving member 110 continuously pushes the rotating rod 121 to rotate, so as to drive the pushing rod 122 and the supporting rod 143 to also continuously rotate, when the pushing rod 122 contacts and pushes against the arc-shaped elastic rod 20, at this time, the pushing rod 122 pushes upwards against the arc-shaped elastic rod 20 to apply a force F1 thereto, and the supporting rod also pushes upwards against the arc-shaped elastic rod 20 through the lever 142 and the socket member 141 to apply a force F2 thereto. In the state shown in fig. 5, when a human body lies on the flexible bearing member 30, the flexible bearing member 30 is pressed down by the weight of each part of the human body and the arc-shaped elastic rod 20 is pressed down, the support rod applies an upward supporting force to the arc-shaped elastic member through the lever and the socket member, and the push rod 122 also applies an upward supporting force to the arc-shaped elastic rod 20. When F > F1+ F2, the arc-shaped elastic rod 20 can move downward, but the amplitude is small, when F = F1+ F2, the arc-shaped elastic rod 20 cannot move downward, and when F < F1+ F2, the arc-shaped elastic rod 20 moves upward. Obviously, with the same F, the mattress becomes stiffer with increasing F1 and F2.

In one embodiment of the present invention, as shown in fig. 7, the sleeve member 141 has a through hole 144, and is sleeved on the arc-shaped elastic rod 20 through the through hole 144. The socket member 141 is provided with a plugging hole 145 below the through hole 144, and one end of the lever 142 is plugged and fixed to the plugging hole 145. It is understood that the structure of said socket 141 can be flexibly changed according to the needs, and any change of the structure of said socket 141 should be considered within the protection scope defined by the claims of the present invention, without departing from the basic idea of the present invention.

Preferably, the socket member 141 is further provided with a protrusion 146, and the protrusion 146 faces the adjacent socket member 141 and contacts therewith, so as to prevent the arc-shaped elastic rod 20 from swinging back and forth when deformed.

In one embodiment of the present invention, the flexible carrier 30 is a plurality of elongated strips of webbing, as shown. The woven belts correspond to the arc-shaped elastic rods 20 one by one, and two ends of the woven belts are connected with two ends 21 of the arc-shaped elastic rods 20 through a connecting piece 150.

In another embodiment of the present invention, the flexible carrier 30 may also be a block-shaped braid, and two opposite sides 31 thereof are connected to two ends 21 of the plurality of arc-shaped elastic rods 20 by a connecting member 150. The connecting member 150 may be flexibly disposed as required, for example, pull rings corresponding to the end portions 21 of the arc-shaped elastic rods 20 one to one are disposed on opposite sides of the knitted fabric, a hole is disposed on the end portion 21 of the arc-shaped elastic rod 20, and the pull ring passes through the hole.

In one embodiment of the present invention, as shown in fig. 1 and 2, the connecting member 150 has a bearing cavity 151, the bearing cavity 151 receives the end 21 of the curved elastic rod 20, the top of the connecting member 150 is provided as a plane 152, and extends from the plane 152 to form a buckle 153, and the side portion 31 of the flexible supporting member 30 passes through the buckle 153 and is inversely stitched on the main portion thereof. The top of the connecting member 150 is a plane 152 flush with the flexible carrier 30, which has an attractive appearance and can prevent the user from feeling hard when touching the connecting member 150. It is understood that the structure of said connecting element 150 can be flexibly changed according to the needs, and any change in the structure of said connecting element 150 without departing from the basic idea of the invention should be considered as being within the protection scope defined by the claims of the present invention.

The driving member 110 may be a motor, a pneumatic piston, or the like, which drives the rotation rod 121 to rotate.

In one embodiment of the present invention, as shown in fig. 3, 4, 5 and 8, the adaptive soft and hard adjustable mattress is further provided with a silent rubber hose 170. The mute rubber tube 170 suspends the arc-shaped elastic rod frame 20 on the bed frame in the air, and can prevent the arc-shaped elastic rod frame 20 from generating noise in the process of deformation or up-and-down movement. Specifically, silence rubber tube 170 is an elastic hose, with arc elastic rod 20 staggered arrangement, be equipped with on the silence rubber tube 170 with the perforation of arc elastic rod 20 one-to-one, every arc elastic rod 20 passes the perforation to unsettled the erection is in on the bed skeleton. When the arc-shaped elastic rods 20 are deformed, the silencing rubber tube 170 separates the adjacent arc-shaped elastic rods 20, so that the adjacent arc-shaped elastic rods 20 are prevented from touching each other to generate friction sound in the deformation process. The silent rubber tube 170 is preferably disposed at the middle position of the arc-shaped elastic rod 20.

Preferably, the adaptive soft and hard adjustable mattress is further provided with a limiting assembly 160, the limiting assembly 160 further comprises a fixing seat 161 and a plurality of mounting columns 162, and the fixing seat 161 is mounted on the bed frame 10, is parallel to the silent rubber tube 170, and is located below the arc-shaped elastic rod 20. The mounting posts 162 are mounted on the fixing base 161 at equal intervals, and each mounting post 162 penetrates through the silent rubber tube 170 between two adjacent arc-shaped elastic rods 20. Thus, the silencing rubber hose 170 is mounted on the fixing base 161. The arc-shaped elastic rod 20 passes through the through hole and is staggered with the silent rubber tube 170, so that the arc-shaped elastic rod 20 is suspended and erected on the bed frame 10. The mounting posts 162 space adjacent ones of the curved elastic rods 20 apart, and when the curved elastic rods 20 are deformed, the silent rubber hose 170 spaces the curved elastic rods 20 and the mounting posts 162 apart from each other, preventing them from touching each other to generate friction sound. The mounting post 162 also serves to maintain the silent hose 170 against collapse. Even if the silent rubber tube 170 slides down to the fixing base 161 along the mounting post 162, by means of the elasticity of the silent rubber tube 170, the specific shape can be maintained and the arc-shaped elastic rod 20 is spaced, and the mounting post 162 and the mounting base 130, so that when the arc-shaped elastic rod 20 is deformed, the silent rubber tube does not directly contact the fixing base 161 and the mounting post 162, thereby generating noise. The mounting post 162 is also a side stop for the deformation of the arc-shaped elastic rod, so as to prevent the side of the arc-shaped elastic rod from being damaged due to the transition deformation.

The limiting assembly 160 further includes a connecting rod 163, and the top of the mounting post 162 is connected to the connecting rod 163. Specifically, a through hole is formed at the top of each mounting post 162, and the connecting rod 163 passes through the through hole at the top of the mounting post 162 to connect the mounting posts. Or, the connecting rod 163 is provided with insertion holes corresponding to the tops of the mounting posts 162 one by one, and one insertion hole is inserted into the top of each mounting post 162. Alternatively, the top of the mounting post 162 is welded, riveted, clamped, etc. to the connecting rod 163. The present invention is not limited to the connection mode, and any change of the connection mode should be considered within the protection scope of the present invention without departing from the basic idea of the present invention.

The self-adaptive soft and hard adjustable mattress is provided with 2-5 groups of the mute rubber tubes 170 and the limiting assemblies 160, wherein the mute rubber tubes 170 and the limiting assemblies 160 are in one-to-one correspondence, and are distributed at equal intervals along the arc-shaped elastic rods 20. Set up a plurality ofly silence rubber tube 170 with spacing subassembly 160 can realize on the one hand the arc pole is unsettled to erect firmly on the bed skeleton 10, on the other hand also can reach the best silence effect, avoids the mattress to warp and makes the sound, influences user's experience and feels and the sleep quality.

The connecting rod 163 has an upper stop function for the arc-shaped elastic rod 20. Specifically, when the arc-shaped elastic rod 20 deforms or moves down,base:Sub>A portion of the arc-shaped elastic rod, which is close to the two end portions 21, contacts the connecting rod 163 of the mute rubber hose 170 located at the outermost side, and the connecting rod 163 prevents the two end portions 21 from further approaching to the central axisbase:Sub>A-base:Sub>A, thereby preventing the arc-shaped elastic rod 20 from being damaged due to transition deformation or from moving down excessively.

The fixing seat 161 has a lower stop function on the arc-shaped elastic rod 20, specifically, the arc-shaped elastic rod 20 deforms or moves down, and the middle point, namely the arc bottom, gradually approaches and abuts against the mounting seat 161 of the silent rubber tube 170 located below the arc bottom. The mounting seat 161 blocks the arc-shaped elastic rod 20 from further deformation, thereby preventing it from being excessively deformed and damaged.
