Abstract

A convective air pad with weight balancing and massage buffering effect, which includes a pad body (1), convective air chamber (2) integrally and uniformly arranged on a surface side of the pad body (1), wherein the convective air chamber (2) is filled with gas, wherein the convective air chamber (2) includes airbag members (21), a convective channel (22) connected between each two adjacently positioned airbag members (21), and a ventilation gap (23) provided between each two adjacently positioned airbag members (21). Through the convective air chamber (2) on the pad body (1), the load-bearing portion is in direct contact with the convective air chamber (2) to provide a very strong weight reducing and pressure buffering effect, thus effectively reduce the stress from the load to the load-bearing portions. The convective air chamber (2) is formed by a number of interconnecting airbag members (21) so that the pressure can be dispersed effectively by gas movement through the convective channels (22), therefore the load is translated into massage effect on the load-bearing parts through the interconnecting airbag members (21) and hence the fatigue and pain in the load-bearing parts is greatly reduced. Moreover, since ventilation gap is formed between the airbag members (21), the contact area between the load-bearing parts is effectively reduced while a superior ventilation effect is provided, hence the heat is dissipated effectively and timely and the comfort level is increased.

Description of Related Arts

In daily life, bag products such as backpacks, waist bags, shoulder bags, arm bags and insoles are commonly used products. The traditional bag products are often only focus on the loading of its functionality. The consideration on the design or purchase is mainly on the number of pockets in a backpack, its loading capacity or its appearance. The consideration on the comfort when using the backpack is rarely taken into account. For insoles, the design is merely focus on its permeability and design which is focused on the comfort to the soles is ignored.
When bag items are used, its weight is generally concentrated on the shoulder, waist, neck or arm of the human body. When the bag is loaded with more items or is used for a long time, these parts of the human body will have long-term pressure and lead to poor local blood circulation and pain may be caused. Also, since the contact parts are not ventilated, sweating is easily resulted and effective heat dissipation is failed. Therefore, people will feel great discomfort, the skin health is affected and a health concern is resulted.
Insoles are positioned at the inner side of the shoes. When wearing, the weight is concentrated on the soles of the feet. When a person is walking, the stress points are sequentially from the heel to the sole. The stress points are varied continuously. Long-term walking can generate different pressure to different parts of the sole and may cause pain. The existing insoles do not have massage effect to the feet and do not have the function of reducing weight.

Compared to the existing technology, the present invention filled the convective air chamber 2 with gas through providing the convective air chamber 2 on the surface of the pad body 1. When in use, the load-bearing parts and the convective air chamber 2 are in direct contact and a buffer effect is provided through the gas, thus providing a very strong weight reducing effect and a decompression buffering effect which can effectively reduce the stress of the loading to the load-bearing parts. Wherein the convective air chamber 2 is formed by a plurality of airbag members 21 while each two adjacently positioned airbag members 21 are inter-connected through the convective channel 22. Therefore, when there is change of force during walking or running, the gas inside the airbag member 21 can effectively disperse the pressure in different directions through the convective channels 22, and can translate the load to massage effect on the load-bearing parts through the plurality of interconnected airbag members. Thus, the blood circulation of the load-bearing parts is maintained while the strain on the load-bearing parts are reduced dramatically. In addition, since ventilation gaps 23 are formed between the airbag members 21, the contact area between the load-bearing parts are greatly reduced while a superior ventilation effect is provided, therefore, the heat is dissipated on a timely manner and the level of comfort is increased. Accordingly, the level of comfort is increased effectively.
According to this embodiment, the pad body 1 and the convective chamber 2 are both made of extendable elastic material. In particular, this includes one or more of plastic materials, rubber materials, silicone materials, leather materials and cloth materials.
The above embodiment is employed and the extendable elastic material such as plastic materials, rubber materials, leather materials, silicone materials and cloth materials is used to make the pad body and the convective chamber. Compared to the traditional sandwich materials or other elastic fabric materials in the existing technology, this can further provide a load reducing effect to the load-bearing parts and increase the level of comfort during use.
According to this embodiment, the convective air chamber 2 is provided to the two sides on the surface of the pad body 1.
When the above embodiment is employed, through providing the convective air chamber on the two sides of the surface of the pad body, the flexibility of the resulting product is greatly increased and hence the level of comfort is increased.
The present invention can also be applied onto the load-bearing portion of bag items, such as the straps of backpacks, the belts of waist bags and the shoulder straps of shoulder bags. The pad body 1 can be secured onto the load-bearing portion of bag items, such as the shoulder straps and the waist belts. In addition, the pad body 1 can also be arranged on a lower side of a backpack such that when the backpack is carried onto a body, the convective air chamber 2 is tightly close to a waist portion, and the position of the convective air chamber 2 is relative to the load-bearing portion of the body. Meanwhile, the pad body 1 can further comprises a positioning strap 3, which is arranged on a front and rear end at two sides of the pad body 1. The positioning strap 3 comprises a Velcro connection. Through the positioning strap 3, the pad body 1 is arranged on the load-bearing portion of the bag items (as shown in Fig. 2). Also, based on the actual need, the pad body 1 and the airbag member 21 can be configured into different shapes, such as circle, square, oval and triangle, to fit the shape of the different load-bearing portions such that it is easy to use and easy to remove. According to this embodiment, the number of convective chamber 2 is three and each of the convective chamber 2 includes nine interconnecting airbag members 21.
On the other hand, according to another embodiment, the present invention can be made into an insole (as shown in Fig. 3 of the drawings). In particular, the pad body 1 is configured into an insole having a shape of an insole. The pad body 1 has a top side and a bottom side and a convective air chamber 2 is provided on each of the top side and the bottom side. The convective air chamber 2 at the top side has nine airbag members 21 while the airbag members 21 are interconnected through the convective channels 22. The convective air chamber 2 at the bottom side has six airbag members 21 while the airbag members 21 are interconnected through the convective channels 22. Wherein the airbag members 21 are having a shape corresponding to the acupuncture points on the toes of the foot and on the soles respectively. During walking, the airbag member 21 is bearing the pressure from the different parts of the sole. The gas inside the airbag member 21 flows to the airbag member 21 which is not acted on by the loading through the convective channels 22 such that the pressure is dispersed and the massage effect on the top and bottom portion of the sole is realized, which can effectively reduce the fatigue and the weight while the comfort level is increased. In addition, the arrangement of providing the convective chamber 2 into a top portion and a bottom portion can prevent the unidirectional gas flow to one side when under pressure and the lowering of the massage effect.
