The external compression body has a top part, a bottom part and a compression elastic component. The top part is configured with an inserting hole. The bottom part is located beneath the top part. The compression elastic component is connected between the top part and the bottom part. The compression elastic component has a folding part. When the top part is pressed, the compression elastic component will accumulate an inverse elastic force. The internal guide slot is formed on the bottom part of the external compression body and located inside the internal space of the external compression body. The internal guide slot has an inserting slot exposing upward. The interior of the inserting slot is formed with a stopping block.

The bottom part of the inserting cylinder is divided into multiple abutting walls corresponding to the stopping block.

BACKGROUND OF INVENTION

The present invention relates generally to a shock-absorbing buffer pad, and more particularly to a shock-absorbing buffer pad with adjustable hardness.

To improve the softness of the bottom part of a pad, a product called “shock-absorbing buffer pad” is usually used on the bottom part of the pad body or inside the pad body, to support the pad body, increase the softness and improve the comfort. For example, in early times, people sleep on wooden board beds or tatami bed. In order to improve the comfort, a thin sleeping pad (such as a Japanese-style sleeping pad) is laid on the wooden board bed or the tatami bed. However, even though the thin sleeping pad provides better softness than sleeping directly on the wooden board bed or tatami bed, it is still not soft and comfortable enough for the sleeper. Therefore, a spring mattress is developed. The product is made by installing springs inside the mattress to greatly increase the softness and comfort. For the mattress, the “spring” is an object similar to the “shock-absorbing buffer pad”.

In early times, during outdoor camping, a waterproof pad is laid on the ground before setting up the tent, so that a sleeping bag can be used inside the tent for sleeping. However, the waterproof pad is too hard for sleeping. Later, a soft pad is used inside the tent for better comfort when sleeping inside the sleeping bag. This soft pad can help reduce the feeling of hardness. Apart from outdoor camping, nowadays more and more people use the car as a sleeping room. They drive to an outdoor environment and sleep right inside the car over night. Some people alter the internal space of the car to adapt to home life. This is becoming more and more trendy. When altering the internal space of a vehicle, generally wooden supporting boards are used as the base layer for sleeping. Then a sleeping pad, or a soft pad, or an air mattress is laid on the wooden board to increase the comfort for sleeping. Along with the increasing popularity of in-car sleeping, a “shock-absorbing buffer pad” is developed. The prior-art shock-absorbing buffer pad is a small object. In actual use, an array of the product is placed on the wooden board base layer, so that the wooden board base layer is covered by multiple shock-absorbing buffer pads. Then, a soft pad is laid above the multiple shock-absorbing buffer pads. Thus, when compressed, the multiple shock-absorbing buffer pads can provide an elastic force, providing better comfort for sleeping. It is a truly good product for outdoor sleeping.

However, the structure of the prior-art shock-absorbing buffer pad can only provide one compression stroke, and therefore can only provide one hardness. In other words, the compression stroke of the prior-art shock-absorbing buffer pad cannot be adjusted to change the hardness. Thus, when a plurality of shock-absorbing buffer pads are distributed, the hardness at a particular area cannot be adjusted to increase comfort. This is the biggest shortcoming of the prior-art shock-absorbing buffer pad.

SUMMARY OF THE INVENTION

In view of the shortcoming that the compression stroke of the prior-art shock-absorbing buffer pad cannot be adjusted to change the hardness, the instant inventor has proceeded in research and development and expects to provide a solution to enable adjustment of the compression stroke to change the hardness of the shock-absorbing buffer pads.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

For better understanding of the technical means of the invention to realize the above object and its functions and benefits, descriptions are provided in detail below with respect to a preferred embodiment and with reference to the accompanying drawings.

Referring toFIG.1˜FIG.6, the present invention is a shock-absorbing buffer pad1, made up of an external compression body10, an internal guide slot20, and an inserted adjusting component30, wherein, the external compression body10has a hexagonal top part11, a hexagonal bottom part12, and a compression elastic component13configured separately and connected to between the edges of the top part11and bottom part12. The center of the top part11has a hexagonal concave positioning slot111, with its center configured with a hexagonal inserting hole112going downward. The outer wall of one side of the positioning slot111is configured with an indicator113(seeFIG.1,FIG.2). The bottom part12is located beneath the top part. The bottom part12is a hexagonal plane with all of its sides corresponding to the sides of the top part11. The center of the bottom part12is provided with a connecting hole121. The compression elastic component13is configured separately and connected between the edges of the top part11and bottom part12. The middle section of the compression elastic component13has a part designed to fold inward (or tilt inward). When the top part11is pressed under an external force, the in-ward folding or tilting phenomenon of the compression elastic component13is increased, so that the overall height of the external compression body10is reduced, and the compression elastic component13accumulates an inverse elastic force. When the external force disappears, due to the inverse elastic force of the compression elastic component13, the external compression body10immediately recovers to its original height and state.

The internal guide slot20is formed on the top surface of the bottom part12, and defined inside the internal space of the external compression body10. The internal guide slot20has an inserting slot21going upward. The cross section of the inserting slot21is hexagonal. Inside the slot, one of the walls is formed with a stopping block22. The stopping block22and the indicator113located above are aligned in the same straight line. A slightly convex positioning block23is formed above the stopping block22.

The top surface of the inserted adjusting component30is hexagonal and can be held inside the top cap31located in the positioning slot111. The internal edges of the six sides of the top cap31are respectively marked with six numbers, namely “0”, “5” “4”, “3”, “2”, “1” (seeFIG.1,FIG.2). The central wall of the top cap31is concave and is configured transversely with a gripping rod311for gripping. The bottom surface of the top cap31is formed with an inserting cylinder32with a hexagonal cross section and which can be inserted into (through) the inserting hole112. Referring toFIG.3,FIG.4, the bottom part of the inserting cylinder32is surrounded with staged abutting walls. Clockwise, they are respectively named as first abutting wall320, second abutting wall325, third abutting wall324, fourth abutting wall323, fifth abutting wall322and sixth abutting wall321. In particular, the height of the first abutting wall320is largest (i.e., its location is lowest), then the location rises sequentially, until the smallest height of the sixth abutting wall321(i.e., its location is highest). The cross section of each abutting wall320,325,324,323,322,321matches that of the stopping block22. Then, at an upper position outside each abutting wall320,325,324,323,322,321, a bar-shaped and slightly concave positioning hole33is provided. The concave position and depth of the positioning hole33matches the convex position and height of the positioning block23. It is specifically configured and noted that, the first abutting wall320goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “0”, the second abutting wall325goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “5”, the third abutting wall324goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “4”, the fourth abutting wall323goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “3”, the fifth abutting wall322goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “2”, the sixth abutting wall321goes straight upward and corresponds to the internal peripheral edge of the top cap31marked with the number “1”.

Based on the above structure, when producing the external compression body10and the internal guide slot20, it is recommended that they are made as an integral body. The inserted adjusting component30is formed separately. Then, during assembly, the inserting cylinder32of the inserted adjusting component30is inserted from the inserting hole112on the top part11into the internal space of the external compression body10, until the top cap31of the inserted adjusting component30is stopped inside the hexagonal concave positioning slot111and fixed. By now, the unused state of the overall shock-absorbing buffer pad1is as shown inFIG.6. As the shock-absorbing buffer pad1is not pressed by an external force at this time, there is still some space between the staged abutting walls320,325,324,323,322,321, particularly the first abutting wall320with the largest height (i.e., lowest location), on the bottom part of the inserting cylinder32, and the stopping block22of the internal guide slot20, they are not contacting each other. The overall height record of the shock-absorbing buffer pad1at this point is set as Hnor, and the height H-nor is the overall maximum height, or normal height, of the shock-absorbing buffer pad1.

Then, the various usage states of the shock-absorbing buffer pad1are depicted inFIG.7(a)FIG.7f). Here, “usage state” means the state when the top part11is subject to an overall downward force that causes downward compression of the shock-absorbing buffer pad1. As described above, the bottom part of the inserting cylinder32is surrounded by staged abutting walls, which are categorized as first abutting wall320, second abutting wall325, third abutting wall324, fourth abutting wall323, fifth abutting wall322and sixth abutting wall321(seeFIG.3,FIG.4). Therefore, when any one of the abutting walls (i.e.,320or325or324or323or322or321) is aligned to the stopping block22, the overall height after compression will have different states. The different usage states are described below with reference toFIG.7(a)˜FIG.7(f):1. First, grip the gripping rod311and move the inserting cylinder32upward to take it out of the external compression body10, then, turn the inserted adjusting component30, until the internal peripheral edge of the top cap31marked with the number “0” is aligned to the position of the indicator113. At this point, the first abutting wall320on the bottom part of the inserting cylinder32is aligned to the stopping block22. Then, the inserting cylinder32of the inserted adjusting component30is again inserted into the inserting hole112, so that the top cap31enters the positioning slot111and is fixed again. Then, when the top part11receives a downward force, causing the shock-absorbing buffer pad1to be compressed downward, as shown inFIG.7(a), during the above process, the positioning hole33at an upper position outside the first abutting wall320will be lowered under the guide of the positioning block23. The action of compression will be limited and stopped when the first abutting wall320touches the stopping block22. The overall height record of the shock-absorbing buffer pad1at this point after compression is set as H320. By comparingFIG.6withFIG.7(a), it is obvious that Hnor>H320.2. If, after the inserting cylinder32as a whole is moved out of the external compression body10, the inserted adjusting component30is turned until the internal peripheral edge of the top cap31marked with the number “5” is aligned to the position of the indicator113. The state at this point is the state when the second abutting wall325on the bottom part of the inserting cylinder32is aligned to the stopping block22. Then, the inserting cylinder32of the inserted adjusting component30is again inserted into the inserting hole112, so that the top cap31enters the positioning slot111and is fixed again. Then, when the top part11receives a downward force, causing the shock-absorbing buffer pad1to be compressed downward, as shown inFIG.7(b), during the process, the positioning hole33at an upper position outside the second abutting wall325will be lowered under the guide of the positioning block23, the action of compression will be limited and stopped when the second abutting wall325touches the stopping block22. The overall height record of the shock-absorbing buffer pad1at this point after compression is set as H325. By comparingFIG.6,FIG.7(a)andFIG.7(b), it is obvious that, Hnor>H320>H325, i.e., when turning the inserted adjusting component30until the second abutting wall325is aligned to the stopping block22, the compression stroke under external force inFIG.7(b)is larger than that inFIG.7(a).3. Based on the above method of adjustment, when turning and adjusting the inserted adjusting component30until the internal peripheral edge of the top cap31marked with the number “4” is aligned to the position of the indicator113, i.e., the third abutting wall324is aligned to the stopping block22. Then, the inserting cylinder32of the inserted adjusting component30is inserted again into the inserting hole112, so that the top cap31enters the positioning slot111and is fixed again. The top part11receives a downward force, causing the shock-absorbing buffer pad1to be compressed downward, as shown inFIG.7(c). During the process, the positioning hole33at an upper position outside the third abutting wall324will be lowered under the guide of the positioning block23. The action of compression will be limited and stopped immediately after the third abutting wall324touches the stopping block22. The overall height record of the shock-absorbing buffer pad1at this point after compression is set as H324. By comparingFIG.6andFIGS.7(a)-(c), it is obvious that, Hnor>H320>H325>H324, and that, when turning and adjusting the inserted adjusting component30until the third abutting wall324is aligned to the stopping block22, the compression stroke under external force inFIG.7(c)is larger than that inFIG.7(b).4. Based on the above method of adjustment, when the internal peripheral edge of the top cap31marked with the number “3” is aligned to the position of the indicator113, the fourth abutting wall323is aligned to the stopping block22, as shown inFIG.7(d). The positioning hole33at an upper position outside the fourth abutting wall323is also lowered under the guide of the positioning block23. The overall height record of the shock-absorbing buffer pad1is H323. By comparingFIG.6andFIGS.7(a)-(d), it is obvious that, Hnor>H320>H325>H324>H323. Therefore, when adjustment is made until the fourth abutting wall323is aligned to the stopping block22, the compression stroke under an external force is longer.5. Based on the above method of adjustment, when the internal peripheral edge of the top cap31marked with the number “2” is aligned to the position of the indicator113, the fifth abutting wall322is aligned to the stopping block22, as shown inFIG.7(e). The positioning hole33at an upper position outside the fifth abutting wall322is also lowered under the guide of the positioning block23. The overall height record of the shock-absorbing buffer pad1is H322. By comparingFIG.6andFIGS.7(a)-(e), it is obvious that, Hnor>H320>H325>H324>H323>H322. Therefore, when adjustment is made until the fifth abutting wall322is aligned to the stopping block22, the compression stroke under an external force is longer.6. At last, when the internal peripheral edge of the top cap31marked with the number “I” is aligned to the position of the indicator113, the sixth abutting wall321is aligned to the stopping block22, as shown inFIG.7(f). The positioning hole33at an upper position outside the sixth abutting wall321is also lowered under the guide of the positioning block23. The overall height record of the shock-absorbing buffer pad1is H321. By comparingFIG.6andFIGS.7(a)-(f), it is obvious that, Hnor>H320>H325>H324>H323>H322>H321. Therefore, when adjustment is made until the sixth abutting wall321is aligned to the stopping block22, the compression stroke under an external force is longest inFIGS.7(a)-(f).

The shock-absorbing buffer pad1of the present invention is suitable for use in combination with a base layer40(for example: wooden board). Therefore, as shown inFIG.8, firstly the inserted adjusting component30is pulled out of the external compression body10, and then a tool (such as a screw driver) is used to screw in a connecting component41(such as a screw) from the inserting hole112, which goes through the inserting slot21and the connecting hole121and is locked with the base layer40, so that the shock-absorbing buffer pad1is stably fixed on surface of the base layer40. Alternatively, as shown inFIG.9, an adhesive component42(such as double-sided adhesive tape) can be applied directly between the shock-absorbing buffer pad1and the base layer40, to similarly fix the shock-absorbing buffer pad1on the surface of the base layer40.

It is better to bond multiple shock-absorbing buffer pads of the present invention1with the base layer40. As shown inFIGS.10and11, a plurality of shock-absorbing buffer pads1are distributed on a base layer40(such as a wooden board) with the hexagons adjacent to each other with a small space between each other. Alternatively, the top part11of the shock-absorbing buffer pad1does not have to be hexagonal. As shown inFIG.12, the top part11is formed in a square shape. Thus, as shown inFIG.13, when arranging the plurality of shock-absorbing buffer pads1, the array is more of square shape. Therefore, the shape of the top part1is not limited, and with the same functioning principle, the shape of the bottom part12of the shock-absorbing buffer pad1is also not limited.

The base layer40is mainly used for laying a sleeping pad for sleeping. Therefore, when using the shock-absorbing buffer pad of the present invention1, the base layer40must be covered with the multiple shock-absorbing buffer pads1before laying the sleeping pad, and the parts of the shock-absorbing buffer pad1corresponding to the head, shoulder, back, waist, hip, thigh, and leg must be adjusted in advance for appropriate pressing degrees. Then, the sleeping pad is laid on the multiple shock-absorbing buffer pads L. Thus, when sleeping on the sleeping pad, the body (and the sleeping pad) will be supported by the multiple shock-absorbing buffer pads1. Because the parts of the shock-absorbing buffer pads1corresponding to different parts of the body are already adjusted for different pressing degrees, the different parts of the body will feel the different supporting and cushioning forces. Then, when the pressure from sleeping is removed, due to the inverse elastic force of the compression elastic components13, the unpressed shock-absorbing buffer pads1will return to its original height and state.

Generally speaking, the head, shoulder, and back part of the human body are best supported by a hard supporting and cushioning force. Therefore, the inserting cylinders32of the shock-absorbing buffer pads1corresponding to the head, shoulder, and back part of the human body are adjusted in advance to align the first abutting wall320or second abutting wall325of the bottom part to the stopping block22. Thus, when the human body lies on the sleeping pad, the ranges of the head, shoulder, and back will sink to the position where the first abutting wall320or second abutting wall325touches the stopping block22and be limited. Therefore, the compression stroke is shorter, and relatively the supporting and cushioning force is harder.

For the waist and thigh parts of the human body, a medium supporting and cushioning force is more appropriate. Therefore, the inserting cylinders32of the shock-absorbing buffer pads1corresponding to the range of the waist and thigh of the human body can be adjusted to let the third abutting wall324or fourth abutting wall323of the bottom part be aligned to the stopping block22. Thus, when the human body lies on the sleeping pad, the area corresponding to the waist and thigh parts will sink until the third abutting wall324or fourth abutting wall323touches the stopping block22and then be limited. This creates a medium compression stroke, and relatively a medium supporting and cushioning force. Similarly, the inserting cylinders32of the shock-absorbing buffer pads1corresponding to the hip and leg parts of the human body can be adjusted, to let the fifth abutting wall322or sixth abutting wall321of the bottom part be aligned to the stopping block22. Thus, when the human body lies on the sleeping pad, the area corresponding to the hip and leg will sink until the fifth abutting wall322or sixth abutting wall321touches the stopping block22and then be limited. This creates a long compression stroke, and relatively a soft supporting and cushioning force.

In the above embodiment, the compression elastic component13is made of a curved material tilting inward. When the top part11is pressed by an external force, the inward-tilting curve of the compression elastic component13will be intensified to accumulate an inverse elastic force. Therefore, with the same functioning principle, the compression elastic component13does not have to be in the design shown inFIGS.1to13, other styles like the compression elastic component131shown inFIG.14, or the compression elastic component132shown inFIG.15, or the compression elastic component133shown inFIG.16can be applied. They can be configured separately and connected between the edges of the top part1I and the bottom part12. The middle section of the compression elastic component131,132,133also has a part and shape folding inward. Therefore, when the compression elastic components131,132,133are respectively connected between the edges of the top part11and the bottom part12, as long as the top part11is pressed by an external force, the compression elastic components131,132,133will likewise have intensified folding, causing lowered height of the external compression bodies10, and the compression elastic components131,132,133will accumulate an inverse elastic force. When the external force disappears, the inverse elastic force of the compression elastic components131,132,133will push the external compression bodies10to recover to its original height and state. Therefore, all compression elastic components similar to the compression elastic components131,132,133with varied designs but same structure and function fall within the patent scope of the present invention.

From the above descriptions, it can be concluded that, the main feature of the present invention is that the structure of the shock-absorbing buffer pad1is made up of an external compression body, an internal guide slot, and an inserted adjusting component. The external compression body has a top part, a bottom part, and a compression elastic component. The center of the top part is configured with an inserting hole going downward. The bottom part is correspondingly located beneath the top part. The compression elastic component is connected between the top part and the bottom part. The middle section of the compression elastic component has a part that is folded inward. When the top part is pressed by an external force, the compression elastic component will immediately accumulate an inverse elastic force. The internal guide slot is formed on the top surface of the bottom part of the external compression body, and is located inside the internal space of the external compression body. The internal guide slot has an inserting slot going upward. The wall body inside the inserting slot is formed with a stopping block. The inserted adjusting component has an inserting cylinder, which can be correspondingly inserted into the inserting hole of the top part. The top surface of the inserting cylinder is positioned around the inserting hole. The bottom part of the inserting cylinder is divided into multiple abutting walls. The abutting walls correspond to the stopping block.

To conclude, the shock-absorbing buffer pad of the present invention can truly accomplish the object and efficacy as expected. Before the application, such a product has not been published or in public use. Meanwhile, it indeed provides improved function and performance and has both novelty and inventive step. Therefore, an application is submitted.
