In order to clarify the purpose and effect of the above-mentioned creations, the features and functions of the present invention will be described in detail in conjunction with the drawings.

First, referring to the first and second figures, the multifunctional backpack 10 of the preferred embodiment includes a backpack body 12 and a backboard 14.

The backpack body 12, like a conventional backpack, includes a bag body 22 for accommodating articles, and two straps 24, 26 are oppositely coupled to the rear side of the bag body 22 for use by the user. The above components are like the components of the conventional backpack, which are conventional technologies, and the detailed structure thereof is not described herein. The backpack body 12 is unique in that the two straps 24 and 26 on the rear side of the bag body 22 are There is further provided a connecting device 28, which comprises two straps 30, 32 and two elastic straps 34, 36 opposite to the rear side of the bag body 22. One end of the two straps 30, 32 are oppositely connected. The top end of the bag body 22 and the other end are respectively provided with a connecting member 38 which can be connected or disassembled, and is a conventional adhesive strip set. The two elastic straps 34 and 36 are oppositely disposed on the bag body 22. Side bottom.

The backing plate 14 is detachably fixed to the rear side of the bag body 22 by the connecting device 28, and includes a deformed member 42 and an elastic body 44. The shaped member 42 has a curved rectangular body, which is made of metal. Plastic or other composite materials, etc. The material is composed of a material having a suitable rigidity and an elastic restoring force. The present embodiment is made of a metal material for being appropriately deformed and returned to the original shape by force. The elastic body 44 is covered with a foam material and has appropriate cushioning property and flexibility. The foam material, such as sponge, foam, EVA, etc., is wrapped around the outside of the shape member 42 to form a curved portion 46 and two extension portions 48, 50 extending from opposite ends of the curved portion 46 in opposite directions. The two extensions 48, 50 are respectively restrained by the two belts 30, 32 and the two elastic bands 34, 36 are pressed. Further, the two side surfaces of the curved portion 46 may be further provided with a plurality of anti-slip ribs (not shown) having a shape such as a straight line or a wave.

Therefore, the multi-function backpack 10 of the present invention has the following features and functions in addition to the conventional backpack to accommodate articles for carrying: as shown in the third figure, when the user bears the multi-purpose backpack 10, The backing plate 14 abuts against the back of the user. The backing plate 14 not only stably supports the fixing member 42 with a suitable rigidity but also the elastic body 40 wrapped around the fixing member 42. The bag body 22 has a comfortable feeling on the back of the user.

Secondly, the backboard 14 can be removed from the multifunctional backpack 10 by disassembling the two straps 30 and 32, and then extracting the backboard 14 from the two elastic straps 34 and 36, which can be used as a lumbar pad. For sleeping pillows. As shown in the fourth figure, when used as a lumbar pad, the back plate 14 is directly placed between the back of the user and the back of the chair 1, as is the use of the conventional waist pad, and the back plate can be used. The curved curvature of 14 and the effect of proper rigidity and elastic restoring force produce the function of supporting the lumbar pad of the waist when backing the seat back 1. When it is intended to be used as a sleepy pillow, as shown in the fifth figure, the extension portion 48 (or the extension portion 50) of the back panel 14 is supported by the upper body of the user (such as the chest or the abdomen), and then hung, On the backboard 14 (head The portion is placed on the curved portion 46, so that the back plate 14 is bent and deformed and placed on the table top 2 for drowsiness, so that the user not only supports the head and the hands, but also the upper body can be extended by the extension. The portion 48 is supported (the elastic force generated by the shaped member 42). Secondly, the plurality of anti-slip ribs provided on the surface of the curved portion 46 can increase the frictional force when the user's head is placed, and make the doze state more stable.

If the backboard 14 is to be fixed back to the backpack body 12, the bottom end of the backboard 14 is simply inserted into the two elastic straps 34, 36, and the two straps 30, 32 are tightened to the backboard 14, and After the two connectors 38 are connected, the back plate 14 can be fixed.

As can be seen from the above, the multi-functional backpack provided by the present invention can be removed or not removed by the user according to the cooperation of the connecting device on the rear side of the backpack body and the back panel, without removing the back panel. The back panel can be used to abut the back of the user, and the effect of supporting the backpack body and the comfort of the backpack are excellent. When the back panel is removed, the back panel can be used as a lumbar cushion or a sleeping pillow. The use of multi-functionality is of practical value; the reason is that this creation does comply with the requirements of the new patent, and applies in accordance with the law.

However, the above description is only a preferred embodiment of the present invention. When it is not possible to limit the scope of the patent protection of the present invention, the simple equivalent change and replacement according to the scope of the patent application and the contents of the specification of the present invention are All should remain within the scope of protection covered by the scope of this patent application.
