Description

Technical field

[0001] The invention relates to a shock-absorbing cushion, in particular to a shock-absorbing cushion capable of adjusting different softness and hardness. [Background Technology]

[0002] When people use a mattress, in order to increase the softness of the bottom, they often place a "shock-absorbing cushion" at the bottom or inside the mattress to support the mattress and increase the softness, making the mattress more comfortable to use. For example, in the early days, people slept on wooden beds or tatami beds, so they generally felt that they were sleeping too hard. Later, in order to seek comfort, they adopted the method of laying a thin sleeping mat (such as a Japanese sleeping mat) on the wooden bed or tatami bed to alleviate the feeling of sleeping too hard. However, although sleeping on a thin sleeping mat is softer than sleeping directly on a wooden bed or tatami bed, it still makes people feel that it is not soft enough and comfortable. Therefore, spring mattresses were later introduced, which adopted the production of adding springs inside the mattress, which greatly improved the overall softness and comfort. Among them, the "spring" here, relative to the mattress, belongs to the category of "shock-absorbing cushion".

[0003] For example, in the early days, when people camped outdoors, they would first lay a waterproof mat on the bottom to prevent water leakage, and then use sleeping bags to sleep inside the tent. Therefore, they generally felt that the bed was too hard. Later, some people first laid a soft mat in the tent to increase the softness, and then slept on the sleeping bag on the soft mat. In this way, the laying of the soft mat can somewhat alleviate the feeling of sleeping too hard. Camping is still popular, and recently it has also become popular to use vehicles as bedrooms and sleep directly in the car in the outdoors (also known as car parking type, car bed type and other names). Some people modify the interior space of the car to make it as close to home life as possible, and this trend is surging. In the modified space of the vehicle, wooden boards are generally used as a base layer for sleeping, and then a sleeping mat, soft cushion or inflatable mattress is laid on the base wooden board to enhance sleeping comfort. As the trend of car parking is currently popular, a new type of "cushion-absorbing pad" has been introduced. The conventional cushioning pad is a small object that is arranged and fixed one by one on the base wooden board when in use, forming a state where a plurality of cushioning pads are arranged on the base wooden board, and then a soft cushion is laid on the plurality of cushioning pads. The elasticity provided by the plurality of cushioning pads when compressed makes the sleeping feeling softer, greatly improving the sleeping comfort of outdoor car parking.

[0004] However, conventional cushioning pads are structurally limited to a single compression stroke, and therefore offer only one hardness. In other words, conventional cushioning pads cannot be adjusted to vary hardness during use. Consequently, when multiple cushioning pads are deployed, they cannot be adjusted to achieve varying hardness within a specific range. This is a significant drawback of conventional cushioning pads, and clearly requires improvement. [Summary of the invention]

[0005] The main purpose of the present invention is to provide a shock-absorbing cushion whose compression stroke can be adjusted to change the softness and hardness.

[0045] See also Figures 1 to 6 As shown, the present invention is a shock-absorbing pad 1, which is structurally composed of an external compression body 10, an internal guide groove 20 and an insert adjustment member 30, wherein the external compression body 10 has a hexagonal top 11, a hexagonal bottom 12 and a compression elastic member 13 provided and connected between each side of the top 11 and the bottom 12. The center of the top 11 has a hexagonal recessed positioning groove 111, and the center is further provided with a hexagonal insertion hole 112 that passes downward. An indicator 113 is provided on the outside of one side of the positioning groove 111 (see Figure 1 、 Figure 2 As shown); the bottom 12 corresponds to the bottom of the top, and the bottom 12 is a hexagonal plane with each side corresponding to the sides of the top 11. A joint hole 121 is provided in the center of the bottom 12. The compression elastic member 13 is separately provided and connected between the top 11 and each side of the bottom 12. The middle section of the compression elastic member 13 has an inwardly folded (also known as inwardly tilted) part and shape. When the top 11 is pushed by an external force, the folding (inwardly tilting) phenomenon of the compression elastic member 13 will increase, causing the overall height of the external compression body 10 to drop. The compression elastic member 13 stores the reverse elastic force, and then after the external force stops, the external compression body 10 returns to its original height and original shape due to the reverse elastic force of the compression elastic member 13.

[0046] The internal guide groove 20 is formed on the top surface of the bottom 12 and exists in the internal space of the external compression body 10. The internal guide groove 20 has an upward insertion groove 21. The cross-section of the insertion groove 21 is hexagonal. A stop block 22 is formed on one of the internal walls. The stop block 22 and the upper indicator 113 are in the same straight line position. A slightly convex positioning block 23 is formed above the stop block 22.

[0047] The top surface of the insert adjustment member 30 is a hexagonal top cover 31 that can be accommodated in the positioning groove 111. The top cover 31 is marked with six numbers "0", "5", "4", "3", "2", and "1" on the inner edge of the six peripheries (see Figure 1 、 Figure 2 As shown), the central wall of the top cover 31 is recessed and provided with a gripping rod 311 for grasping. The bottom surface of the top cover 31 is downwardly formed with an insertion tube 32 having a hexagonal cross section and correspondingly insertable into (through) the insertion hole 112. Figure 3 、 Figure 4As shown, the bottom of the insertion tube 32 is surrounded by abutment walls arranged in a stepped manner, for example, when viewed clockwise, it is divided into a first abutment wall 320, a second abutment wall 325, a third abutment wall 324, a fourth abutment wall 323, a fifth abutment wall 322 and a sixth abutment wall 321, wherein the first abutment wall 320 is the highest (i.e., its position is the lowest), and then it gradually rises upward clockwise until the height of the sixth abutment wall 321 is the smallest (i.e., its position is the highest), and the cross-sectional shape of each abutment wall 320, 325, 324, 323, 322, 321 corresponds to the abutment block 22, and then a long, slightly concave positioning hole 33 is provided on the upper outer side of each abutment wall 320, 325, 324, 323, 322, 321. The recessed position and depth of the positioning hole 33 correspond to the protruding position and height of the positioning block 23; it is particularly set and explained that the first abutment wall 320 corresponds to the number "0" marked on the inner edge of the periphery of the top cover 31 in a straight line upward, the second abutment wall 325 corresponds to the number "5" marked on the inner edge of the periphery of the top cover 31 in a straight line upward, the third abutment wall 324 corresponds to the number "4" marked on the inner edge of the periphery of the top cover 31 in a straight line upward, the fourth abutment wall 323 corresponds to the number "3" marked on the inner edge of the periphery of the top cover 31 in a straight line upward, the fifth abutment wall 322 corresponds to the number "2" marked on the inner edge of the periphery of the top cover 31 in a straight line upward, and the sixth abutment wall 321 corresponds to the number "1" marked on the inner edge of the periphery of the top cover 31 in a straight line upward.

[0048] According to the above structure, the external compression body 10 and the internal guide groove 20 are preferably formed in the same body when they are manufactured, and the insertion adjustment member 30 is formed separately. Then, when assembling, the insertion tube 32 of the insertion adjustment member 30 is inserted into the internal space of the external compression body 10 from the insertion hole 112 on the top 11 until the top cover 31 of the insertion adjustment member 30 stays in the positioning groove 111 of the hexagonal recess. At this time, the unused state of the shock absorber pad 1 as a whole is as follows: Figure 6 As shown, it can be seen that because the shock-absorbing pad 1 is not pushed by external force at this time, the stepped abutment walls 320, 325, 324, 323, 322, and 321 at the bottom of the insertion tube 32, especially the first abutment wall 320 with the highest height (i.e., the lowest position), are still at a distance from the abutment block 22 of the internal guide groove 20 and are not in contact. The overall height of the shock-absorbing pad 1 at this time is recorded as Hnor, and the height Hnor is the overall highest height of the shock-absorbing pad 1, or the normal height.

[0049] Then the various use states of the shock absorbing pad 1 are as follows Figure 7(a) to Figure 7(f)As shown, the so-called "use" here refers to the state when the top 11 is subjected to a force applied from top to bottom, causing the cushioning pad 1 to be compressed downward as a whole. Because as mentioned above, the bottom of the insertion tube 32 is surrounded by a stepped abutment wall, which can be divided into a first abutment wall 320, a second abutment wall 325, a third abutment wall 324, a fourth abutment wall 323, a fifth abutment wall 322 and a sixth abutment wall 321 (see Figure 3 、 Figure 4 As shown), whichever abutting wall (i.e. 320 or 325 or 324 or 323 or 322 or 321) is aligned with the abutting block 22, the overall height after being compressed will present different states. Figure 7(a) to Figure 7(f) The following are the different usage conditions of the matching instructions:

[0050] When the cam 320 is in contact with the stopper 22, the cam 321 is in contact with the stopper 22, and the cam 322 is in contact with the stopper 22. When the cam 321 is in contact with the stopper 22, the stopper 322 is in contact with the stopper 22. When the cam 321 is in contact with the stopper 22, the stopper 322 is in contact with the stopper 22. When the cam 321 is in contact with the stopper 22, the stopper 322 is in contact with the stopper 22. Figure 6 Compared with Figure 7(a), it can be seen that Hnor>H320.

[0051] When the second stopper 325 abuts against the stopper 22, the top cover 31 is retracted and the second stopper 325 is released. Figure 67(a) and 7(b), it can be seen that Hnor>H320>H325, that is, when the insertion adjustment member 30 is rotated to adjust the second abutment wall 325 to be aligned with the abutment block 22, the stroke after being pressed downward by force in FIG7(b) is larger than that in FIG7(a).

[0052] 3. According to the above adjustment method, when the insertion adjustment member 30 is rotated to adjust to the position of the number "4" marked on the inner edge of the top cover 31 to the position of the pointer 113, which is exactly the state of the third abutment wall 324 aligning (aligning) with the block 22, the insertion tube 32 of the insertion adjustment member 30 is then inserted into the insertion hole 112 again, so that the top cover 31 enters the positioning groove 111 and is repositioned. Then, the top 11 is subjected to a force applied from top to bottom, causing the buffer shock absorber 1 to be compressed downward as a whole, as shown in Figure 7 (c). During this process, the positioning hole 33 on the upper outer side of the third abutment wall 324 will be guided downward by the positioning block 23. The compression action is limited and stopped when the third abutment wall 324 abuts against the block 22. The overall height of the buffer shock absorber 1 after compression at this time is recorded as H324. Figure 6 7(a), 7(b) and 7(c), it can be seen that Hnor>H320>H325>H324. It can be seen that when the insertion adjustment member 30 is rotated to adjust the third abutment wall 324 to be aligned with the abutment block 22, the stroke after being pressed downward by force in FIG7(c) is larger than that in FIG7(b).

[0053] 4. Following the above adjustment method, when the number "3" marked on the inner edge of the top cover 31 is adjusted to the position of the pointer 113, and the fourth abutting wall 323 is aligned with the abutting block 22, after being compressed, as shown in Figure 7 (d), the positioning hole 33 above the outer side of the fourth abutting wall 323 is also guided down by the positioning block 23, and the overall height of the shock absorbing pad 1 is recorded as H323. Figure 6 7(a), 7(b), 7(c) and 7(d), it can be seen that Hnor>H320>H325>H324>H323, so when the fourth abutting wall 323 is adjusted to be aligned with the abutting block 22, the stroke after being pressed downward is longer.

[0054] 5. Following the above adjustment method, when the number "2" marked on the inner edge of the top cover 31 is adjusted to the position of the pointer 113, that is, when the fifth abutting wall 322 is aligned with the abutting block 22, after being compressed, as shown in Figure 7 (e), the positioning hole 33 above the outer side of the fifth abutting wall 322 is also guided down by the positioning block 23, and the overall height of the shock absorbing pad 1 is recorded as H322. Figure 67(a), 7(b), 7(c), 7(d) and 7(e), it can be seen that Hnor>H320>H325>H324>H323>H322, that is, when the fifth abutting wall 322 is adjusted to be aligned with the abutting block 22, the stroke after being pressed downward is longer.

[0055] 6. Finally, when the number "1" marked on the inner edge of the top cover 31 is adjusted to the position of the pointer 113, and the sixth abutting wall 321 is aligned with the abutting block 22, after being compressed, as shown in Figure 7(f), the positioning hole 33 on the upper side of the sixth abutting wall 321 is also guided down by the positioning block 23, and the overall height of the shock absorbing pad 1 is recorded as H321. Figure 6 7(a), 7(b), 7(c), 7(d), 7(e) and 7(f), it can be seen that Hnor>H320>H325>H324>H323>H322>H321, that is, when the sixth abutting wall 321 is adjusted to align with the abutting block 22, the stroke after being pressed downward is Figure 7(a) to Figure 7(f) The longest in.

[0056] The shock absorbing pad 1 of the present invention is suitable for being assembled on a base layer 40 (for example, a wooden board). Figure 8 As shown, first pull the insert adjustment member 30 away from the external compression body 10, then use a tool (e.g., a screwdriver) to drive a joint member 41 (e.g., a screw) into the insert hole 112, pass through the insert slot 21 and pass through the joint hole 121, and then achieve a locking joint with the base layer 40, so that the shock absorbing pad 1 is firmly combined with the surface of the base layer 40; or as Figure 9 As shown, an adhesive member 42 (eg, double-sided tape) is directly bonded between the shock absorbing pad 1 and the base layer 40 , so that the shock absorbing pad 1 can be firmly bonded to the base layer 40 .

[0057] The present invention is suitable for using the shock absorbing pad 1 in combination with the base layer 40 in a plurality of quantities. Figure 10 、 Figure 11 As shown, a plurality of cushioning pads 1 are arranged on the same base layer 40 (e.g., a wooden board) in a hexagonal shape adjacent to each other and spaced a little apart. Alternatively, the top 11 of the cushioning pad 1 is not necessarily a hexagonal shape, but may be as shown in FIG. Figure 12 As shown, the top 11 is formed into a square, so that Figure 13 As shown, most of the shock absorbing pads 1 are arranged in a relatively square shape, so the shape of the top 11 is not limited, and under the same working principle, the shape of the bottom 12 of the shock absorbing pad 1 is also not limited.

[0058] The base layer 40 is mostly used for laying a sleeping pad for lying down. Therefore, when using the cushioning and shock-absorbing pad 1 of the present invention, it is necessary to first combine the plurality of cushioning and shock-absorbing pads 1 on the base layer 40 before laying the sleeping pad, and select the cushioning and shock-absorbing pads 1 corresponding to the head, shoulders, back, waist, buttocks, thighs, and calves to adjust the appropriate degree of pressure first, and then lay the sleeping pad on the plurality of cushioning and shock-absorbing pads 1. In this way, when lying down on the sleeping pad, the body (and sleeping pad) is supported by the plurality of cushioning and shock-absorbing pads 1 below, and because the degree of pressure of the cushioning and shock-absorbing pads 1 in each part has been adjusted in advance, different parts of the body will feel different load-bearing and buffering forces below; then when the external force of lying down is removed, the cushioning and shock-absorbing pad 1 that is not under force will return to its original height and original state due to the reverse elastic force of the compression elastic member 13.

[0059] Generally speaking, it may be more appropriate to support the head, shoulders and back of the human body with a more rigid load-bearing and buffering force. Therefore, the insertion tube 32 of the shock-absorbing pad 1 corresponding to the head, shoulders and back of the human body is adjusted in advance so that the first abutting wall 320 or the second abutting wall 325 at the bottom is aligned with the abutting block 22. In this way, when the human body lies down, the head, shoulders and back area sinks to the point where the first abutting wall 320 or the second abutting wall 325 abuts against the abutting block 22 and is restricted and stopped. Therefore, it can have a shorter compression stroke, which means it has a relatively rigid load-bearing and buffering force.

[0060] It may be more appropriate to support the waist and thighs of the human body with a relatively moderate load-bearing and buffering force. Therefore, the insertion tube 32 of the shock-absorbing pad 1 corresponding to the waist and thigh range of the human body can be adjusted so that the third abutment wall 324 or the fourth abutment wall 323 at the bottom is aligned with the abutment block 22. In this way, when the human body lies down, the waist and thigh range sinks to the point where the third abutment wall 324 or the fourth abutment wall 323 abuts against the abutment block 22 and is restricted and stopped. Therefore, there can be a moderate compression stroke performance, which is relatively a moderate load-bearing and buffering force. By the same token, the insertion tube 32 of the shock-absorbing pad 1 corresponding to the buttocks and calf area of ​​the human body can be adjusted so that the fifth abutment wall 322 or the sixth abutment wall 321 at its bottom is aligned with the abutment block 22. Therefore, when the human body lies down, the buttocks and calf area sinks to the point where the fifth abutment wall 322 or the sixth abutment wall 321 abuts against the abutment block 22 and is restricted and stopped. Therefore, it can have a longer compression stroke, which means it has a relatively softer load-bearing and buffering force.

[0061] In the above embodiment, the compression elastic member 13 is a curved surface with an inward curvature. When the top 11 is pushed by an external force, the inward curvature of the compression elastic member 13 is aggravated to store the reverse elastic force. Therefore, under the same structure, the compression elastic member 13 does not necessarily need to be as Figures 1 to 13 The shape shown, others as Figure 14 The compression elastic member 131 shown in FIG. Figure 15 The compression elastic member 132 shown, or Figure 16 The compression elastic members 133 shown in the figure can also be separately provided and connected between the top 11 and the sides of the bottom 12, and the middle sections of the compression elastic members 131, 132, 133 also have inwardly bent parts and shapes. Therefore, when the compression elastic members 131, 132, 133 are respectively connected between the top 11 and the sides of the bottom 12, as long as the top 11 is pushed by an external force, the inward bending phenomenon of the compression elastic members 131, 132, 133 will also be increased, so that The overall height of the external compression body 10 is lowered, and the compression elastic members 131, 132, and 133 store reverse elastic force. Then, when the external force stops, the reverse elastic force of the compression elastic members 131, 132, and 133 acts to push the external compression body 10 to return to its original height and shape. Therefore, compression elastic members similar to the compression elastic members 131, 132, and 133, which have some changes in shape but have the same structure and function, are all within the scope of protection of the present invention.

[0062] From the above description, it can be seen that the biggest feature of the present invention is that the structure of the buffer shock absorber 1 is composed of an external compression body, an internal guide groove and an insertion adjustment piece. The external compression body has a top, a bottom and a compression elastic piece. An insertion hole is opened in the center of the top and passes through it downward. The bottom corresponds to the bottom of the top. The compression elastic piece is connected between the top and the bottom. The middle section of the compression elastic piece has an inwardly bent part. When the top is pushed by force, the compression elastic piece stores reverse elastic force; the internal guide groove is formed on the bottom top surface of the external compression body and exists in the internal space of the external compression body. The internal guide groove has an insertion groove that passes upward, and a resistance block is formed on the wall of the interior of the insertion groove; the insertion adjustment piece has an insertion tube, which can be inserted into the insertion hole of the top. The top surface of the insertion tube stays outside the insertion hole. The bottom of the insertion tube is divided into a plurality of abutment walls, which correspond to the resistance block.
