Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a backpack, and more particularly to a backpack having a weight warning function. [Prior Art] Due to the implementation of nine years of national education, most children have the opportunity to study. In the past, children in school age usually went to school with their lightweight backpacks.
但隨著社會環境越來越競爭，兒童們不得不提早吸收更多 知識’再加上教育政策一綱多本的實施，導致書包裡所裝 的教科書、參考書越來越多，也造成兒童每天都必須背著 好幾公斤的書包上學。然而，學齡兒童正處在骨路發育期 長’月煮負過重書包的情況下，不僅對於骨骼的發育產生 不良的衫響’ 4重的書包再加上背負姿勢不正確，更有可 能導致脊椎側彎或是傷害等情形發生。 參閱圖1為解決上述問題，便有如中華民國公告第 9515號新型專利案所揭露的「護脊背& 1」，供一使用 (見圖2)|負，該護脊背包丨包含—袋體U、二設置 於該袋體U後侧面上緣的肩帶12，及多數個貼置於該袋體 11後側面的緩衝墊13。 ，+參閱圖2’當使用者咖將該護脊背包i背負於背部時 藉由該―肩冑12(因視角的關係於圖中只顯示1個肩帶 )的束、身’可使所述緩衝墊13是緊貼使用者1〇〇的背脊上 \疋並維持使用者1〇〇的正確挺立姿勢。而所述軟質 的緩衝塾13可將袋體11的重量平均分擔於使用者100的背 201038223 部’可避免因單點壓迫而造成使用者100的不舒適與疼痛 感。 然而，小朋友總是有好勝心及責任感，希望將所有會 用到的書藉都放到背包裡，而再重的背包還是想要證明自 己有力氣可以背負，因此上述的護脊背包1雖能均勻分擔 袋體11的重量，但仍無法讓老師及家長馬上清楚得知小朋 友的書包是否過重’進而從旁提醒與協助。而且除了對於 骨路發育產生不良的影響之外，背包過重也讓小朋友走在 路上忽然要閃躲車子時，因閃避不及而發生危險。 因此，如何發展出一種可以馬上清楚得知總重量的背 包，便成為相關業者亟需努力的目標。 【發明内容】 因此，本發明之目的，即在提供一種具有重量警示功 能的背包。 於是，本發明一種具有重量警示功能的背包，供一使 用者填裝物品後背負使用，該具有重量警示功能的背包包 含-用以填裝物品的承載體、至少―連接於該承載體的背 帶、-設置於該背帶的電源、一設置於該背帶並與該電源 電連接的荷重單元、—電連接於該荷重單元的控制單元， 及一電連接於該控制單元的警示單元。 其中，該背帶具有一與該使用者接觸的下表面，而該 荷重單元是設置於該下表面；該荷重單元是用以量測該承 載體及其填裝之物品的整體重量，並將-量測而得的重量 訊號傳遞至該控制單元；而該控制單元是依據該荷重單元 201038223 所傳遞的重量訊號來調控該警示單元的運作。 本發明之功效在於’由該荷重單元是用以量測該承載 體及其填裝之物品的整體重量’因此當重量過重時，該控 制單元會調控該警示單元發出訊號，用以提醒師長注意， 來有效避免兒童背負過重的背包，進而減少對身體及發育 上所產生的不良影響。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 Ο 以下配合參考圖式之四個較佳實施例的詳細說明中，將可 清楚的呈現。 在本發明被詳細描述之前，要注意的是，在以下的說 明内容中’類似的元件是以相同的編號來表示。 參閱圖3及圖4，本發明具有重量警示功能的背包2之 第一較佳實施例，供一使用者200(只見於圖4)填裝物品2〇1 後背負使用，該具有重量警示功能的背包2包含一用以填 裝物品201的承載體21、二連接於該承載體21的背帶22 〇 、一鼓置於§亥月帶22上的電源23、一設置於該背帶22並 與該電源23電連接的荷重單元24、一電連接於該荷重單元 24的控制單元25’及一電連接於該控制單元25的警示單 元26 ’該警示單元26具有多數個發光二極體261、262， 及 263。 於本實施例中，該背包2是包含二連接於該承載體21 的背帶22 ’供使用者200背負於背部，當然也可以視實際 製造情形，只有一連接於該承載體21的背帶22，供使用者 5 201038223 200側背或是斜背於一側的肩肖上，因此不應以本實施例所 揭露的内容為限。 每一为帶22分別具有一與使用者2〇〇接觸的下表面 221，及一相反於該下表面221的上表面222，而於正常使 用狀態下，每一背帶22所承受的重量是一致的，因此該電 源23、荷重單元24，及控制單元25皆是設置於其中一個 背帶22的下表面221，於本實施例中，該電源23是設置於 該上表面222，便於使用者2〇〇進行更換的動作，當然也可 以視情況设置於其他易於更換的地方，且該電源23可以為 一般市售之扁平鋰電池的態樣，也可以是採用充電電池的 態樣，皆可以達到提供電力的功能，因此該電源23的設置 位置及種類不應受本實施例所提及的態樣而偈限。 參閱圖4及圖5 ’該荷重單元24是用以量測該承載體 21及其填裝之物品2〇1的整體重量並將一重量訊號傳遞 至該控制單元25;而該控制單元25是依據該荷重單元24 所傳遞的重量訊號來調控該警示單元26的運作，於本實施 例中’該警示單元26是具有三個發光二極體261〜263，並 依據该荷重單元24所傳遞的重量訊號而使不同的發光二極 體261〜263發出不同的光線。 以下則介紹該具有重量警示功能的背包2的使用方法 ’當使用者200將一整天上課所需的物品201，如：教科書 、參考書等放入該承載體21 ’並利用所述背帶22來背負於 背部’此時該荷重單元24所偵測到的是該承載體21及其 填裝之物品201的整體重量’而於本實施例的設計，是以 201038223 二個階段作為區分： ⑴該荷重單元24偵測到的重量為Q〜2公斤時，並將 该重量訊號傳遞至該控制單元25，該控制單元25則調控第 一個發光二極豸261發出綠色光線，代表目 可以容許的範圍裡； 疋在 :°亥何重單兀24偵測到的重量為2〜4公斤時，並將 該重量訊號傳遞至該控制單元25，該控制單元25則調控第However, as the social environment becomes more and more competitive, children have to absorb more knowledge early. Together with the implementation of the education policy, the number of textbooks and reference books in the schoolbags has increased, which has also caused children. Every day, I have to carry a few kilograms of schoolbags to school. However, school-age children are in the long-term development of the bone path. In the case of a heavy over-the-shoulder bag, not only does it have a bad shirt on the development of the bones. 4 The weight of the bag plus the posture of the back is incorrect, and it is more likely to cause the spine. Side bends or injuries occur. Referring to Figure 1 to solve the above problems, there is a "back protection & 1" as disclosed in the Republic of China Announcement No. 9515, for use (see Figure 2)|negative, the ridge backpack includes - bag body U, two shoulder straps 12 disposed on the upper edge of the rear side of the bag body U, and a plurality of cushions 13 attached to the rear side of the bag body 11. , + see Figure 2 'When the user's coffee bag carries the ridged backpack i on the back, the shoulders 12 (only one shoulder strap is shown in the figure due to the angle of view) can be used. The cushion 13 is in a correct standing posture which is in close contact with the user's back ridge and maintains the user's 1 。. The soft cushioning 13 can evenly distribute the weight of the bag 11 to the back portion 201038223 of the user 100 to avoid the discomfort and pain of the user 100 due to a single point of compression. However, the children always have a sense of enthusiasm and responsibility. They hope that all the books they will use will be put in their backpacks, and the heavy backpacks still want to prove that they have the strength to bear, so the above-mentioned ridge backpack 1 The weight of the bag body 11 can be evenly distributed, but the teacher and the parents are still unable to immediately know whether the child's school bag is too heavy, and then remind and assist from the side. In addition to the adverse effects on the development of the bone path, the heavy weight of the backpack also makes the children walk on the road and suddenly want to dodge the car, which is dangerous because it is not evasive. Therefore, how to develop a back pack that can clearly know the total weight immediately becomes a target that the relevant industry needs to work hard. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a backpack having a weight warning function.

To the control unit 25, the control unit 25 regulates the third illuminating two (four) 263 to emit red light, indicating that the current weight is too heavy, and reminds the teacher or the parent to assist in the processing immediately; and the above three-stage design is only the embodiment. One embodiment mentioned may of course be changed according to the actual manufacturing situation and with different grades of low, medium and high. When the backpack 2 with weight warning function is suitable for students of lower grades, the bearer The volume of the body 21 is small and the weight το 24 is a warning light that is designed to emit red light when it is (four) to a small weight; if the student of the middle and highton uses it, the capacity of the carrier 21 can be appropriately increased. And the control unit 25 receives the heavier weight signal to control the warning light of the red light emitted by the LED 263. In addition, the light-emitting diodes 261 263 263 can be illuminated by different frequency flickers in addition to emitting light of different colors. When the weight detected by the load cell 24 is β, When you are in the range of the valley, '疋 flashes at a lower frequency; when the weight is _, the weight detected by the ordinary 24 is too heavy', it flashes at a faster frequency to achieve the purpose of reminding attention. All of the above are the ways in which the actual manufacturing can be changed. = This should not be limited to the above-mentioned lighting modes and weight restrictions. With the above-mentioned designation 10, the backpack 2 having the weight warning function of the present invention has the following advantages in practical use: (1) An immediate warning effect can be achieved: When the carrier 21 and its contents are loaded 2〇 When the overall weight of 1 exceeds a certain limit, by the setting of the warning unit 26, the reminder or the warning can be immediately realized, so that the teacher or the parent can assist the child to overweight or unnecessary items in the backpack 2. 2 01 is taken out. (2) Protecting the future of the country: As mentioned above, when the backpack 2 is within the appropriate weight range, it can effectively prevent the child's shoulders and the spine from being subjected to excessive pressure, thereby reducing the weight of the backpack 2 The phenomenon of scoliosis or injury is caused, and the child has a healthy physique to achieve the purpose of protecting the future of the country. (3) Detecting a more accurate weight: Since the s-ship carrier 21 itself has a certain weight, and the load unit 24 is disposed on the lower surface 221 of one of the straps 22, the load unit 24 measures The weight of the carrier 21 and its loaded article 201 as a whole is not only the weight of the article 201 filled in the carrier 21 of 201038223, so that a relatively accurate weight can be detected. Referring to FIG. 6 , a second preferred embodiment of the backpack 2 having the weight warning function is substantially similar to the first preferred embodiment. The difference is that the warning unit 26 is disposed on the carrier 21 . The same can be used to remind the warning, and the location is more prominent so that teachers and parents can easily see and provide another choice. Referring to FIG. 7, a third preferred embodiment of the backpack 2 having a weight warning function is substantially similar to the foregoing first preferred embodiment, except that the warning unit 26 is in the form of a buzzer. When the load unit 24 transmits the weight signal to the control unit 25, and the control unit 25 determines that it is too heavy, the alarm unit 26 is regulated to sound to remind the teacher or the parent to assist in processing immediately to reach the reminder. The role of warnings and offers another way of choosing. In this embodiment, the warning unit 26 is disposed on one of the straps 22, and may be disposed on the carrier 21 according to an actual manufacturing situation, so as to achieve the function of alerting, and therefore should not be implemented in this embodiment. The set position disclosed in the example is limited. Referring to FIG. 8, a fourth preferred embodiment of the backpack 2 having the weight warning function of the present invention is substantially similar to the first preferred embodiment described above, except that the control unit 25 includes a control panel that can input commands from the outside world. 251 'and a controller 252 electrically connected to the control panel 251, the load unit 24, and the warning unit 26. The design of the control panel 25 1 can be used to adjust the reference of the controller 252 to control the operation of the warning unit 26, such as the light-emitting diode 26 mentioned in the first preferred 201038223 embodiment. 262, 263 are different in 0~2, 2~4, 4~6 kg, which will emit different light to reach the reminder. However, as the user 200 grows older, the physique is stronger, and the weight of the month can also be reduced. With a relative increase, the adjusted reference can be input through the control panel 25i to adjust the controller 252 to regulate the operation of the warning unit 26, so that the LEDs 261, 262, and 263 are heavier in weight. Different lights will be emitted to achieve the reminder, and the backpack 2 with the reset warning function is more applicable. Children are the pillars of the country's future. In addition to giving correct knowledge and opinions in education, they should be properly cared for and protected in terms of physique and health. Therefore, the backpack 2 with weight warning function has been placed. When the item 201 of f is used, an immediate warning function can be achieved, so that the teacher or the parent can immediately assist in the treatment, and effectively avoid the child carrying the overweight backpack and the shirt is rang out of its normal development, so that the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the description of the invention. All remain within the scope of the invention patent.
