Description

Technical Field

[0001] The utility model relates to a back plate structure in a backpack carrying system, in particular to a decompression back plate. Background Art

[0002] The academic pressure on modern schoolchildren is increasing, and the most direct manifestation is the increasing weight of their backpacks. Backpacks are filled with various school supplies, and the weight of primary school students' main subject books alone reaches about 10kg. Daily backpacks have an important impact on children's good posture, bone development, and even physical and mental health. The weight of children's backpacks has become the primary concern of parents.

[0003] On the other hand, a backpack is defined as overweight if its total weight exceeds 15% of body weight. An overweight backpack can lead to incorrect backpacking posture, which can easily cause neck, shoulder and back pain, spinal deformity, lumbar muscle soreness and cold back problems. In addition, the stress points of existing backpacks are too concentrated on the shoulders, which can easily fatigue the shoulder and back muscles, and the backpacks can easily fall backwards, causing teenagers to have compensatory incorrect postures such as leaning forward, hunching over, and stretching their heads forward.

[0004] As the skeleton of the backpack's carrying system, the back panel plays an important role in dispersing pressure. The back panel structure design of existing backpacks is not ideal, and the support for the waist and back is insufficient, resulting in excessive concentration of pressure and inability to effectively disperse the pressure.

[0005] In view of the above problems, there is an urgent need for a decompression backboard that can scientifically distribute pressure points, reasonably disperse pressure to the whole body, and reduce the weight. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a decompression backboard that can be designed according to the characteristics of the pressure points on the back of the human body, scientifically distribute the pressure points, reasonably disperse the pressure to the whole body, and reduce the weight.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a decompression backboard, which is improved in that it includes a backboard body, a first shoulder and back part, a second shoulder and back part and a lumbar support part, the first shoulder and back part include a first raised strip, the second shoulder and back part include a second raised strip, the first shoulder and back part and the second shoulder and back part are arranged on both sides of the backboard body, the lumbar support part is arranged below the first shoulder and back part and the second shoulder and back part, and the first shoulder and back part include a recessed air groove between the second shoulder and back part.

[0008] In the above technical solution, first attached raised strips are arranged on both sides of the first raised strip, and second attached raised strips are arranged on both sides of the second raised strip.

[0009] In the above technical solution, the thickness of the first attached protrusion strip is 50% of the first protrusion strip, and the thickness of the second attached protrusion strip is 50% of the second protrusion strip.

[0010] In the above technical solution, the first raised strip and the second raised strip are raised flexible supporting side panels.

[0011] In the above technical solution, the first raised strip, the second raised strip, the first attached raised strip and the second attached raised strip are all streamlined, and their shapes correspond to the shapes of the waist and back muscles on both sides of the human spine.

[0012] The decompression backboard in the above technical solution is made of mercerized cotton fabric, and the mercerized cotton fabric is made of 60S double-ply cotton yarn spun from long-staple cotton, and is a honeycomb structure with a mesh structure.

[0013] The beneficial effects of the utility model are as follows: the utility model takes into account the force principle of the human back, combines the bone force points and muscle trends, and scientifically and reasonably designs the back panel shape. The raised strips on the left and right sides cover the triangular shoulder blades on both sides of the human back, and extend to the waist while taking into account the main shoulder and back muscle groups such as the trapezius, infraspinatus muscles, and latissimus dorsi muscles. The pressure can be transferred and dispersed through the main bone contact points and muscle groups, and the force areas of the waist, back, and shoulders are connected to form a soft transition, which also plays a protective role so that the muscles will not be fatigued and tense for a long time. The air grooves on the back panel allow the heat and sweat stains in the more sweating areas to flow through the air in the air grooves to accelerate quick drying, thereby reducing the damp, hot and stuffy redness caused by sweating on the back and the close contact with the back panel fabric, providing a good and healthy backpack experience. The mercerized cotton fabric used is breathable and comfortable, wear-resistant and durable, skin-friendly and soft, sweat-absorbent and easy to dry, more comfortable, healthy, environmentally friendly and sustainable.

[0023] Reference Figure 1 As shown, the utility model provides a decompression backboard, including a backboard body 4, a first shoulder and back part 1, a second shoulder and back part 2, a lumbar support part 3 and a hollow air groove 5, the first shoulder and back part 1 includes a first raised strip 1-1, the second shoulder and back part 2 includes a second raised strip 2-1, the first shoulder and back part 1 and the second shoulder and back part 3 are arranged on both sides of the backboard body 4, and the lumbar support part 3 is arranged below the first shoulder and back part 1 and the second shoulder and back part 2.

[0024] like Figure 2 As shown, the first shoulder and back parts 1 and the second shoulder and back parts 2 include a concave hollow groove 5 between them.

[0025] Among them, first attached raised strips 1-2 are arranged on both sides of the first raised strip 1-1, and second attached raised strips 2-2 are arranged on both sides 2-1 of the second raised strip. The thickness of the first attached raised strip 1-2 is 50% of the first raised strip 1-1, and the thickness of the second attached raised strip 2-2 is 50% of the second raised strip 2-1.

[0026] Among them, the first raised bar and the second raised bar are raised flexible supporting side panels, and the first raised bar, the second raised bar, the first attached raised bar and the second attached raised bar are all streamlined, and their shapes correspond to the shapes of the waist and back muscles on both sides of the human spine.

[0027] Among them, the pressure-relief back panel is made of mercerized cotton fabric, which is made of 60S double-ply cotton yarn spun from long-staple cotton, and has a honeycomb structure with a mesh structure.

[0028] like Figure 3 As shown, during the backpacking process, the pressure points of the spine are distributed on the shoulders and back, and the force points are mainly concentrated on the muscles of the shoulders and upper back. The muscles of the shoulders and upper back support and move the backpack by contracting and relaxing. Specifically, the muscle groups of the back, such as the trapezius, rhomboids and teres major, will participate in supporting and balancing the weight of the backpack. In addition, the muscles of the shoulders, such as the deltoids and triceps, will also participate in supporting and adjusting the position of the backpack. These muscles will gradually exert force when the backpack is loaded, and continue to exert force when walking or moving to maintain balance and stability.

[0029] Specifically, muscle strength is generated by muscle contraction, and its magnitude depends on the number, volume, properties, length of muscle fibers before contraction and the excitement state of the central nervous system. The weight of the backpack is first pressed on the shoulders through the shoulder straps, causing compression on the levator scapulae and trapezius muscles of the shoulders. During walking, in order to prevent the shoulder straps from sliding down, the shoulders need to be lifted up. At this time, the trapezius and levator scapulae muscles in the shoulder area must contract together to generate muscle strength. However, since the shoulder muscles are compressed by gravity, the muscle strength required for muscle contraction is much greater than the muscle strength required in the unloaded state. Therefore, the degree of muscle fatigue generated by the muscles will also be greatly increased. Carrying activities for too long or carrying too much weight will increase the workload of the shoulder muscles, which is prone to shoulder muscle strain and ischemia and pain.

[0030] At the same time, the center of gravity of the backpack is raised, and the scattered items inside cause uneven weight distribution. During walking, the items will generate a backward component of force, dragging the shoulder straps, thereby exerting a certain amount of pressure on the human clavicle. Moreover, during running, the items in the bag will swing back and forth, repeatedly hitting the child's back, affecting the normal development of the back bones and muscles.

[0031] The design of the decompression backboard in the utility model takes into account the anatomical structure and muscle distribution of the human back, and is intended to provide comfortable support and relieve pressure. Among them, the backboard body is the main body of the entire decompression backboard, providing an overall support structure; the first shoulder back and the second shoulder back are respectively located on both sides of the backboard, used to bear and disperse the pressure of the shoulders, and they include a raised bar structure, the shape of which matches the anatomical structure of the human back to provide better support and stability; the lumbar support is located below the first shoulder back and the second shoulder back, used to support the waist and provide additional stability; the hollow groove is located in the concave structure between the first shoulder back and the second shoulder back, which helps to relieve the pressure of the back and improve ventilation; the raised bars and the attached raised bars are located at the edges of the first shoulder back and the second shoulder back, and their design can better adapt to the curve of the human back and disperse the pressure at the same time; all the raised bars and the attached raised bars adopt a streamlined design, corresponding to the shape of the human spine and waist and back muscles, to ensure better fit and comfort; the decompression backboard is made of mercerized cotton fabric and has a honeycomb structure with a mesh structure, which can improve ventilation and reduce moisture and discomfort on the back.

[0032] Through the above process, the decompression backboard of the utility model effectively reduces the pressure on the shoulders and back through the comprehensive application of structural design, material selection and ergonomic principles, providing a more comfortable backpacking experience.

[0033] The existing back panels have technical problems such as the overall height being consistent from top to bottom, not conforming to the physiological characteristics of the natural S-shaped curvature of the human spine, no air grooves in the central spine part to wick away sweat and breath, and the disconnection between the upper back and the shoulder point being disconnected, resulting in the inability to naturally and smoothly connect and transition the force on the shoulders and back.

[0034] The utility model designs the backboard according to the characteristics of the back pressure points of school-age children, and takes all-round design considerations into account according to the distribution position, size and shape of the back pressure points. The scientific distribution of each pressure point reasonably transfers the pressure to the whole body, thereby reducing the weight pressure of the school bag, which is beneficial to the healthy development of the spine of school-age children.

[0035] Aiming at the deficiencies of the prior art and the back plate designs of school bags on the market, the utility model makes scientific improvements to the decompression zone to conform to the bone points and the direction of the muscles, and makes reasonable planning of the sweat discharge zone and the decompression zone.

[0036] The back panel of the utility model is provided with raised flexible supporting side panels located on the left and right sides respectively, which are used for supporting the streamlined left raised strip and right raised strip for supporting the waist and back muscles on both sides of the spine. Both sides of the two raised strips are provided with attached protrusions which are 50% thinner than the two raised strips as the thickness transition zone from the back force center area to the edge. A concave hollow groove is formed between the two protrusions. Below the two raised strips is a waist support protrusion for supporting the lower waist muscles.

[0037] Specifically, the existing back panel is mainly divided into a protruding three-dimensional back panel and a recessed air groove. The function is to form a shock-absorbing and load-reducing effect through the three-dimensional high elasticity of the fabric. The back panel surfaces have different shapes and distributions. The overall height of the back panel from top to bottom is consistent, which does not conform to the physiological characteristics of the natural S-shaped curvature of the human spine. There is no air groove in the central spine part, which cannot wick sweat and breathe. The back panel design does not conform to the physiological angle and usage scenarios.

[0038] In addition, the connection between the upper back and the shoulder point of some existing back panels is disconnected, and the force on the shoulders and back cannot be naturally and smoothly connected and transitioned.

[0039] Compared with the backboards on the market, the backboard design in the utility model comprehensively considers the force principle of the child's back, and scientifically and rationally designs the backboard shape in combination with the bone force points and muscle trends. The raised strips on the left and right sides cover the triangular shoulder blades on both sides of the human back, and extend to the waist. At the same time, the movement influence of major shoulder and back muscle groups such as the trapezius muscle, infraspinatus muscle, and latissimus dorsi muscle is taken into consideration. When the human body is in motion with a schoolbag on its back, the pressure can be transferred and dispersed through the major bone contact points and muscle groups. At the same time, the force areas of the waist, back, and shoulders are connected to form a soft transition, which also plays a protective role so that the muscles will not be fatigued and tense for a long time.

[0040] Furthermore, most of the existing back panels are integrally filled with cotton or partially suspended in design, and have no sweat and heat dissipation function or the effect is unsatisfactory, causing students' backs to suffer from discomfort or related skin diseases due to heat.

[0041] The utility model plans the sweating zone for the sweat-prone areas on the back of children, and identifies the area that is more prone to sweating as the central spine area based on the thermal imaging image of the human back. The air grooves on the back panel are designed in this way so that the heat and sweat stains in the area that is more prone to sweating can be accelerated to dry quickly through the air flow in the air grooves, thereby reducing the damp, hot and stuffy redness caused by sweating on the back and the close contact between the back panel fabric, giving students a good and healthy backpack usage experience.

[0042] Furthermore, the back panel in the utility model adopts mercerized cotton fabric, which is made of 60S double-ply cotton yarn spun from long-staple cotton, and then woven into a honeycomb structure with a mesh structure. After mercerization treatment, the fabric is breathable and comfortable, wear-resistant and durable, skin-friendly and soft, sweat-absorbent and easy to dry. Compared with existing chemical fiber mesh fabrics, it is more comfortable, healthy, environmentally friendly and sustainable.

[0043] Specifically, the back panel body provides an overall support structure corresponding to a wide range of muscle areas of the back, including the latissimus dorsi, trapezius, etc. This structure disperses weight and pressure and reduces the burden on the shoulders and back; the first shoulder back and the second shoulder back are located on the shoulders, and through specially designed raised bars and attached raised bars, they correspond to shoulder muscles such as the levator scapulae, provide additional support and stability, and reduce fatigue and pressure on the shoulder muscles; the lumbar support is located under the back, corresponding to the waist and back muscles, providing support and stability for the waist, thereby dispersing the pressure on the back; the design of the hollow air groove helps to reduce the pressure on the back, and reduces local pressure concentration by reducing the surface area in contact with the back; the design of the raised bars and attached raised bars takes into account the curve of the human back, corresponds to the shape of the back muscles, disperses pressure, reduces local pressure points, and improves comfort. All raised bars and attached raised bars adopt a streamlined design, which is adapted to the shape of the human spine and waist and back muscles, ensuring better fit and comfort while reducing the burden on the muscles.

[0044] Compared with the prior art, the present application designs a backboard according to the distribution characteristics of pressure points on the back of the human body. The pressure is reasonably transferred and dispersed to the whole body through the scientific distribution of each pressure point, thereby reducing the weight pressure of the school bag, which is beneficial to the healthy development of the spine of school-age children. Comprehensive design considerations are made based on the distribution position, size and shape of the pressure points on the back: the shoulder points, scapula points and lumbar sacral bone points on both sides of the spine are mainly used as the main force points to form three backboards of the shoulder, back and waist support. The three backboards are symmetrically distributed, and the upper and lower areas overlap, connected to the shoulder straps and the lower waist support. The pressure of the school bag is reasonably relieved in the direction of muscle contraction through the main contact points in a point-to-surface manner. At the same time, hollow air grooves are left in the main spine and the sweat-prone positions under the shoulders and ribs, which are conducive to the direct evacuation of heat, so that the backboard is sufficiently fitted without stuffy sweat, which has certain advantages.

[0045] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
