具雙軸心之安全帽下巴護罩定位裝置Helmet hood positioning device with double shaft

本創作係有關於一種具雙軸心之安全帽下巴護罩定位裝置，特別是指於帽體與下巴護罩之間形成兩固定軸及轉動軸，並於其中一固定軸之軸心設置彈簧，而能藉彈簧之拉力將下巴護罩拉至帽體中心者。The present invention relates to a hood hood positioning device with a biaxial core, in particular to form two fixed shafts and a rotating shaft between the cap body and the chin guard, and a spring is arranged on the axis of one of the fixed shafts. , and can pull the chin guard to the center of the cap body by the tension of the spring.

按，習用之全罩式安全帽1，請配合參閱第1圖所示，一般係由一帽體11及下巴護罩12所組成，而該帽體11與下巴護罩12之間係設有一轉軸13，使下巴護罩12能以轉軸13為軸心轉動，以控制下巴護罩12之掀起或蓋闔，並能藉由配戴全罩式安全帽1以降低受衝擊時對於頭部所造成之傷害，由於該帽體11及下巴護罩12均具有一定重量，因此平時配戴時其重量係平均分配於頭部，然而，當將下巴護罩12掀起時，轉軸13則容易因多次的轉動而造成螺絲磨損或鬆脫，使下巴護罩12因重量或頭部動作而滑動，無法穩定定位於帽體11，當下巴護罩12突然滑動時，容易使頸部無法承受其重量而前傾，長久下來將會造成頸部負擔並累積成傷害，故其轉軸結構實有改良之必要。According to FIG. 1 , the utility model generally comprises a cap body 11 and a chin guard 12 , and a structure between the cap body 11 and the chin guard 12 is provided. The rotating shaft 13 enables the chin guard 12 to pivot about the rotating shaft 13 to control the lifting or covering of the chin guard 12, and can be worn by the full-face helmet 1 to reduce the impact on the head. The damage caused by the cap 11 and the chin guard 12 has a certain weight, so the weight is evenly distributed to the head when worn normally. However, when the chin guard 12 is lifted, the shaft 13 is easily replaced. The rotation of the screw causes the screw to be worn or loosened, so that the chin guard 12 slides due to the weight or the head movement, and cannot be stably positioned on the cap body 11. When the chin guard 12 suddenly slides, the neck cannot easily bear its weight. And leaning forward, long-term down will cause the burden on the neck and accumulate damage, so the shaft structure is necessary to improve.

創作人係專門從事於安全帽之設計開發工作，深知傳統安全帽其下巴護罩之轉軸無法確實定位，且容易因多次的轉動而磨損，於是乃萌發改良之決心並極力苦思解決之道，終於在歷經數次的試驗與改進後，首創出本創作。The creator specializes in the design and development of helmets. He knows that the traditional safety helmet's chin's hinge can't be positioned correctly, and it is easy to wear due to repeated rotations. Therefore, it is the determination to improve and solve it. Tao, finally, after several trials and improvements, the original creation.

The other end is fixed to the notch 2221, and the rotating shaft 7 has a square groove 71 corresponding to the protrusions 221, 231, 421 and 521, and a through hole 72 is formed in the groove.

接著，請仍然參閱第2圖所示，組裝時，係將彈簧6置於圓形槽22內，並使彈簧6之一端固定於環狀框222之缺口2221定位，而彈簧6之另一端則套設於第二軸片5之圓孔53內，並將轉軸扣7穿過第一軸片4及第二軸片5之穿孔41、51，使轉軸扣7之凹槽71能嵌合於帽體2之凸塊221及231，並將螺絲穿過透孔72與凸塊221、231之槽孔2211、2311鎖固，以形成兩固定軸，並將轉動軸7穿過下巴護罩3之通孔31、32，使轉動軸7之凹槽71與第一 軸片4及第二軸片5之凸塊421、521嵌合，並藉螺絲穿過轉軸扣7之透孔72而與第一軸片4及第二軸片5之槽孔4211、5211鎖固，以形成兩轉動軸。Next, please refer to FIG. 2 again. When assembling, the spring 6 is placed in the circular groove 22, and one end of the spring 6 is fixed to the notch 2221 of the annular frame 222, and the other end of the spring 6 is The sleeve 7 is sleeved in the circular hole 53 of the second shaft piece 5, and the rotating shaft buckle 7 is passed through the through holes 41, 51 of the first shaft piece 4 and the second shaft piece 5, so that the groove 71 of the rotating shaft buckle 7 can be fitted to The bumps 221 and 231 of the cap body 2, and the screws are inserted through the through holes 72 and the slots 2211, 2311 of the bumps 221, 231 to form two fixed shafts, and the rotating shaft 7 is passed through the chin guard 3 Through holes 31, 32, the groove 71 of the rotating shaft 7 and the first The protrusions 421 and 521 of the shaft piece 4 and the second shaft piece 5 are fitted, and are locked by the through holes 72 of the rotating shaft buckle 7 and the slots 4121 and 5211 of the first shaft piece 4 and the second shaft piece 5 by screws. Solid to form two axes of rotation.

請接著參閱第3圖所示，係本創作軸心結構之示意圖，當下巴護罩3蓋闔於帽體2時，第二軸片5與下巴護罩3之通孔32鎖固所形成之轉動軸係位於弧形槽21上端，而第一軸片4與下巴護罩3之通孔31鎖固所形成之轉動軸係位於弧形槽21下端，此時，彈簧6係隨第二軸片5之轉動軸位置而扭轉，而當下巴護罩3掀起時(請配合參閱第4圖)，則能以第一軸片4、第二軸片5與帽體2鎖固所形成的固定軸為軸心，將第一軸片4、第二軸片5與下巴護罩3鎖固所形成之轉動軸連動，使下巴護罩3移置至帽體2上端，接著，藉彈簧6之拉力將第二軸片5拉至弧形槽21之邊緣(如第5圖所示)，使第二軸片5貼抵於弧形槽21並讓彈簧6回復定位，而能藉轉動軸將下巴護罩3之重心移至帽體2之中央處定位，使下巴護罩3不易因重量或頭部動作而前傾甚至向下滑落，因此，能降低安全帽重量對於頸部所造成之負擔。Please refer to FIG. 3, which is a schematic diagram of the axial structure of the present invention. When the chin guard 3 is placed on the cap 2, the second shaft 5 and the through hole 32 of the chin guard 3 are locked. The rotating shaft is located at the upper end of the curved groove 21, and the rotating shaft formed by the locking of the first shaft 4 and the through hole 31 of the chin guard 3 is located at the lower end of the curved groove 21. At this time, the spring 6 is connected with the second shaft. The rotation axis of the sheet 5 is twisted, and when the chin guard 3 is lifted (please refer to FIG. 4), the first shaft piece 4, the second shaft piece 5 and the cap body 2 can be fixed by locking. The shaft is an axial center, and the first shaft piece 4 and the second shaft piece 5 are interlocked with the rotating shaft formed by the locking of the chin guard 3, so that the chin guard 3 is displaced to the upper end of the cap body 2, and then, by the spring 6 The pulling force pulls the second shaft piece 5 to the edge of the curved groove 21 (as shown in Fig. 5), so that the second shaft piece 5 abuts against the curved groove 21 and allows the spring 6 to return to the position, and can be rotated by the rotating shaft The center of gravity of the chin guard 3 is moved to the center of the cap body 2, so that the chin guard 3 is not easily tilted forward or even downward due to weight or head movement, thereby reducing the weight of the helmet caused by the neck. burden.

此外，該帽體2與第一軸片4及第二軸片5上所設之凸塊221、231、421及521係能以多邊形呈現(請回顧第2圖)，而轉軸扣7之凹槽71亦能設為與上述凸塊221、231、421及521對應之多邊形槽，而能使多邊形凸塊嵌合於多邊形槽時，不易因鎖固之螺絲磨損或鬆脫而讓固定軸及轉動軸空轉，使下巴護罩3能穩固定位於帽體2，並延長下巴護罩3之開闔次數。In addition, the cap body 2 and the protrusions 221, 231, 421 and 521 provided on the first shaft piece 4 and the second shaft piece 5 can be represented by a polygon (please refer to FIG. 2), and the concave shaft buckle 7 is concave. The groove 71 can also be a polygonal groove corresponding to the protrusions 221, 231, 421 and 521, and when the polygonal protrusion is fitted into the polygonal groove, it is not easy to fix the shaft due to wear or looseness of the locking screw. The rotating shaft is idling, so that the chin guard 3 can be stably fixed to the cap body 2, and the number of opening of the chin guard 3 is extended.

綜上所述，本創作透過於帽體與下巴護罩之間形成兩固定軸 及轉動軸，並於其中一固定軸之軸心設置彈簧，而能藉彈簧之拉力將下巴護罩拉至帽體中央定位，以減少下巴護罩之重量對於頸部所造成的負擔，實以較傳統安全帽更為進步、實用，理應符合新型專利之要件，爰依法提出專利申請。In summary, the creation creates two fixed axes between the cap and the chin guard. And rotating the shaft, and providing a spring on the axis of one of the fixed shafts, and pulling the chin guard to the center of the cap body by the tension of the spring, so as to reduce the burden on the neck caused by the weight of the chin guard, More advanced and practical than traditional helmets, it should meet the requirements of new patents, and file patent applications according to law.
