Description of the new type: [Technical field to which the new type belongs] This creation relates to a golf bag tire structure, especially a heavy-duty, light-inflatable, shock-absorbing elasticity, and good mud and snow grip The structure of ground power. [Previous technology] According to the conventional tires used in golf bag carts for golf equipment, they are roughly divided into three types: EVA solid foam tires, rubber inflatable tires and thin rubber tires. Among them, thin rubber tires 1. As shown in the first figure, because the tire wall is thin and the shock absorption effect is poor, it is less common. As shown in the second figure, the rubber pneumatic tire 2 is the same as a bicycle tire and contains an inner tube. The disadvantage is that it is heavy and has a small contact area with the ground. It is easy to leave tire marks on the soft ground and damage the grass. Inflatable maintenance from time to time. As shown in the third figure, EVA solid foam tire 3 has the advantages of light weight, no inflation, and shock absorption elasticity, so it is currently used by most golf bag carts. 〃 However, the above two types of rubber pneumatic tires 2 and · solid foam tires 3 are only suitable for use on dry grass. When the ball is soft under the rainy weather, the ground will become slippery or muddy. If the rubber pneumatic tire 2 is to increase the contact area with the ground and deepen the tread pattern, the aforementioned problem of poor grip force causes the tire weight to increase greatly and the construction is not suitable for golf bags. Because of the limitation of production conditions, the EM solid foam tire emperor cannot increase and deepen the tread pattern, so the grip provided on the mud and ground is also quite limited. In view of this, the creator germinated the idea of improvement. After conscientious research and design of M281812, the author finally produced this creation. [New content] The reason is that the main purpose of this creation is to provide a golf bag tire structure that has good grip and is suitable for driving on mud and snow, so as to eliminate the lack of knowledge in one fell swoop.
為達上述目的，本創作係包含有一 EVA實心發泡内胎 及一薄外胎；其中，該内胎外侧胎壁係具有多數之橫向凹 槽，而薄外胎係由具彈性之軟質材料製成，其内侧胎壁並具 有多數之橫向凸肋，俾與内胎之橫向凹槽卡合，而外侧胎壁 則具有多數之凸粒，俾可深入泥地或雪地，而提供良好的抓 地力者。 【實施方式】 茲舉二較佳可行實施例配合附圖，詳述本創作之構造 及特徵如下，俾使貴審查委員能深入瞭解且認同者。 首先，請參見第四、五圖所示，本創作係包含一 EVA 實心發泡内胎4及一薄外胎5 ;其中，該内胎4外侧胎壁 係具有多數之橫向凹槽41，而薄外胎5係可由橡膠或TPE 或TPU等具有彈性之軟質材料製成，並略呈门形，其内側 胎壁係具有多數之橫向凸肋51，俾與内胎之橫向凹槽41 卡合，外側胎壁則具有多數等高且等厚並呈尖圓柱狀之凸 粒52。 組合後如第五圖所示，薄外胎5係利用本身彈性與 EVA實心發泡内胎4外緣緊密套合，並藉橫向凸肋51與 橫向凹槽41二者之卡合，以避免薄外胎5與EVA實心發 泡内胎4二者之間產生空轉或滑動之現象，同時再藉薄外 胎5外緣所設呈尖圓柱狀之凸粒52，而可深入泥地或雪 5 M281812 地，以提供良好的抓地力，使高爾夫球袋車可順利行馱； 另外，倘於非雨季或下雪的冬季時，本創作亦可將薄外胎 5卸下，直接利用EVA實心發泡内胎4當做輪胎使用。 故由以上之說明可知，本創作巧妙地利用EVA實心發 泡内胎4搭配具凸粒52之薄外胎，而構成一種複合式實心 輪胎，不但具有重量輕免充氣且具有避震彈性等優點，加 上具有呈尖圓柱狀之凸柱52，而可提供良好的泥地或雪地 抓地力，顯然遠比習知者更為進步實用。 再請參見第六、七圖所示，本創作之EVA實心發泡内 胎4’在外緣兩侧係各具有一凸牆42，使内胎4,外側具有 一環形凹槽，而内胎4’外侧胎壁同樣地亦具有多數之橫向 凹槽41’ ；薄外胎5 ’係可呈一環形薄片狀，内外也同樣地 具有多數之橫向凸肋51，與凸粒52’；組合時係將薄外胎5, 緊密套合於該EVA實心發泡内胎4,之環形凹槽内，再藉 板向凹槽41，與橫向凸肋51’之卡合，使内外胎二者結合成 一實心發泡輪胎，以達與上述第一實施例相同之功效，此 即本創作之第二實施例。 综上所陳，本創作實施例所揭露之具體構造，經查確 為習知者所無，並且更具有可提供良好的泥地或雪地抓地 力，堪稱為一既新穎且實用又進步之創作，爰依法提出新 型專利申請。 M281812 【圖式簡單說明】 第一圖所示係習知高爾夫球袋車使用之橡膠薄胎之立體圖 第二圖所示係習知高爾夫球袋車使用之橡膠充氣胎之立體 圖 第三圖所示係習知高爾夫球袋車使用之EVA實心發泡胎之 立體圖 第四圖所示係本創作第一實施例之立體分解圖 第五圖所示係本創作第一實施例之組合剖視圖 第六圖所示係本創作第二實施例之立體分解圖 第七圖所示係本創作第二實施例之組合剖視圖 【主要元件符號說明】 習知部分： 1—橡膠薄胎 2—橡膠充氣胎 3 -一EVA實心發泡胎 本創作部分： 41、41’…橫向凹槽 5、5’…薄外胎 52、52’…凸粒 4、4’…EVA實心發泡内胎 42…凸牆 51、51’—橫向凸肋In order to achieve the above purpose, this creative system includes an EVA solid foamed inner tube and a thin outer tube. Among them, the outer wall of the inner tube has a plurality of transverse grooves, and the thin outer tube is made of a flexible soft material with an inner side. The tire wall has a large number of lateral ribs, and the cymbals are engaged with the lateral grooves of the inner tube, while the outer tire wall has a large number of bulges, which can penetrate deep into the mud or snow and provide good grip. [Embodiment] Two preferred and feasible embodiments are given in conjunction with the drawings to describe the structure and characteristics of this creation in detail, so that your reviewing committee can understand and agree with it. First, as shown in the fourth and fifth figures, this creative system includes an EVA solid foam inner tube 4 and a thin outer tube 5. Among them, the outer wall of the inner tube 4 has a plurality of lateral grooves 41, and the thin outer tube 5 It can be made of rubber or TPE or TPU and other flexible soft materials and has a slightly door shape. Its inner tire wall has a large number of transverse ribs 51, which are engaged with the lateral grooves 41 of the inner tube. The outer sidewall is There are a plurality of convex particles 52 of the same height and thickness and having a cylindrical shape. As shown in the fifth figure after the combination, the thin tire 5 series uses its own elasticity to tightly fit with the outer edge of the EVA solid foamed inner tube 4 and uses the engagement of the lateral ribs 51 and the lateral grooves 41 to avoid thin tires. 5 and EVA solid foamed inner tube 4 will cause the phenomenon of idling or sliding between the two, and at the same time, by the thin cylindrical 5 outside the sharp edge of the cylindrical convex particles 52, and can penetrate deep into the mud or snow 5 M281812, Provides good grip to make the golf bag cart run smoothly; In addition, if it is not in the rainy or snowy winter, this creation can also remove the thin outer tube 5 and use the EVA solid foam inner tube 4 directly as the tire use. Therefore, from the above description, this creation cleverly uses the EVA solid foamed inner tube 4 and the thin outer tube with convex 52 to form a composite solid tire, which not only has the advantages of light weight, no inflation, and shock absorption elasticity. It has a sharp cylindrical pillar 52 on the top, which can provide good grip on mud or snow, which is obviously far more advanced and practical than those who are familiar with it. Please refer to the sixth and seventh figures. The EVA solid foam inner tube 4 'of this creation has a convex wall 42 on each side of the outer edge, so that the inner tube 4 has an annular groove on the outer side, and the inner tube 4' outer tire The wall also has a large number of transverse grooves 41 '; the thin outer tube 5' can be in the shape of a ring-shaped sheet, and the inner and outer portions also have a large number of lateral ribs 51 and convex particles 52 '; when combined, the thin outer tube 5 Closely fit in the annular groove of the EVA solid foamed inner tube 4, and then engage the groove 41 through the plate to engage with the lateral ribs 51 ', so that the inner and outer tires are combined into a solid foamed tire. Achieve the same effect as the first embodiment described above, this is the second embodiment of this creation. To sum up, the specific structure disclosed in this creative embodiment has been found to be unknown to those who know it, and it also has a good grip on mud or snow, which can be described as a novel, practical and progressive For his creation, he filed a new patent application according to law.
