Description
本創作係與自行車輪圈有關；特別是指一種嵌入一輪圈半成品之對接端內，以形成一完整輪圈之接合件。This creation is related to the bicycle rim; in particular, it is a kind of joint that fits into the butt end of a semi-finished product of a rim to form a complete rim.
現有一種自行車輪圈之製造方法，係先將一鋁擠型空心長條依一定的弧度折彎，以形成其兩端相面對之輪圈半成品，再以一接合件自該兩端塞入該輪圈半成品中，以連接該兩端，進而形成完整的圓形輪圈。A bicycle rim manufacturing method is characterized in that an aluminum extruded hollow strip is bent at a certain curvature to form a rim semi-finished product facing the two ends, and then inserted into the two ends by a joint member. In the semi-finished product of the rim, the two ends are connected to form a complete circular rim.
一種習用之接合件，如台灣新型專利第M452874號所示，係以鋁材經擠製成形。為能塞入輪圈半成品中，它必須呈現相同於輪圈半成品之弧度的彎弧狀，因此，這種習用之接合件在製造上必須經過一或數道的彎折加工程序，而使得其製造成本提高。又，上述的彎折加工容易產生誤差，導致該接合件經常因彎曲之弧度不同於該輪圈半成品的弧度而無法塞入輪圈半成品中。因此，此種接合件之製造良率不足，同時也成為提高製造成本的原因。A conventional joint member, as shown in Taiwan's new patent No. M452874, is extruded into an aluminum material. In order to be inserted into the rim semi-finished product, it must exhibit the same curvature as the arc of the rim semi-finished product. Therefore, the conventional joint member must be subjected to one or several bending processes in manufacturing, so that Manufacturing costs increase. Moreover, the above-mentioned bending process is prone to error, and the joint member is often unable to be inserted into the rim semi-finished product because the curvature of the bending is different from the curvature of the semi-finished product of the rim. Therefore, the manufacturing yield of such a joint member is insufficient, and at the same time, the manufacturing cost is also increased.
除此之外，上述習用接合件容易因其本身於被製造時之尺寸誤差，或是因輪圈半成品內壁之厚度不均勻，而無法塞入輪圈半成品中，或與輪圈半成品之內壁間具有過大的間隙，致使無法牢固地結合該輪圈半成品之兩端。In addition, the above-mentioned conventional joint member may be easily inserted into the semi-finished product of the rim or the semi-finished product of the rim due to its own dimensional error during manufacture or due to uneven thickness of the inner wall of the rim semi-finished product. There is an excessive gap between the walls, so that the ends of the rim semi-finished product cannot be firmly joined.
有鑑於此，本創作之目的在於提供一種自行車 輪圈半成品之接合件，係一製造成本低廉，並可緊密且固地結合輪圈半成品之相對端者。In view of this, the purpose of this creation is to provide a bicycle The joint of the rim semi-finished product is low in manufacturing cost and can be combined with the opposite end of the rim semi-finished product in a tight and solid manner.

請參閱圖1~圖3，本創作一較佳實施例之接合件10，係適用於一種以鋁合金空心長條管經裁切及彎折後所形成之輪圈半成品20。如圖2及圖3所示，該輪圈半成品20之兩端相對且各具有一開口21，而該接合件10則用以分別自該二開口21塞設入該輪圈半成品20中，以接合該輪圈半成品20之兩端，形成一完整圓形的輪圈。另外，上述之輪圈半成品20具有一外側部22、一內側部23位於該外側部22之相反側、以及二側部24分別連結該外側部22以及該內側部23，其中，該外側部22具有一結合槽221，用以結合一輪胎(圖未示)。Referring to FIG. 1 to FIG. 3, the joint member 10 of the preferred embodiment of the present invention is suitable for a rim semi-finished product 20 formed by cutting and bending an aluminum alloy hollow strip. As shown in FIG. 2 and FIG. 3, the two ends of the rim semi-finished product 20 are opposite to each other and each has an opening 21, and the engaging member 10 is respectively inserted into the rim semi-finished product 20 from the two openings 21, The ends of the rim semi-finished product 20 are joined to form a complete circular rim. In addition, the rim semi-finished product 20 has an outer portion 22, an inner portion 23 on the opposite side of the outer portion 22, and two side portions 24 that respectively join the outer portion 22 and the inner portion 23, wherein the outer portion 22 There is a coupling groove 221 for combining a tire (not shown).
請再參閱圖2，本實施例之接合件10係一鋁擠型管件，具有一第一部11、一第二部12、一第三部13以及一第四部14，在該接合件10塞設於該輪圈半成品20中時，該第一部11至該第四部14分別面向且貼接於外側部22、該內側部23以及該二側部24之內壁。另外，該接合件10具有一手段，用以使該接合件10緊密地別自該輪圈半成品20的該二開口21塞設入該輪圈半成品20中者。在本實施例中，該手段為該第一部11、第二部12、第三部13及該第四部14上所設置之各二切槽15(cut)，且各個部上的該二切槽15，係自各該部11、12、13、14之接近二端處分別延 伸至該二端。Referring to FIG. 2 again, the joint member 10 of the present embodiment is an aluminum extruded tubular member having a first portion 11, a second portion 12, a third portion 13 and a fourth portion 14 at the joint member 10. When being inserted into the rim semi-finished product 20, the first portion 11 to the fourth portion 14 face and adhere to the outer portion 22, the inner portion 23, and the inner walls of the two side portions 24, respectively. Additionally, the engagement member 10 has a means for closely engaging the engagement member 10 from the two openings 21 of the rim semi-finished product 20 into the rim semi-finished product 20. In this embodiment, the means are the two cuts 15 provided on the first portion 11, the second portion 12, the third portion 13 and the fourth portion 14, and the two on each portion The slits 15 are respectively extended from the two ends of the respective portions 11, 12, 13, and 14. Reach to the two ends.
請配合參閱圖1、圖3及圖4，使用該接合件10於該輪圈半成品20上時，係使該接合件10之第一部11、第二部12、第三部13及第四部14分別對應於該輪圈接合件10之外側部22、內側部23及二側部24，並以其兩端分別自該二開口21塞入該輪圈半成品20中，使該接合件10之第一部11至第四部14分別朝向該輪圈半成品20之外側部22、內側部23及二側部24，且貼接於各該部22、23、24之內壁。在將該接合件10塞入該輪圈半成品20的過程中，須儘量維持該接合件10塞入該輪圈半成品20之二端的深度相同，亦即，使該輪圈半成品20之兩端相向地對接於該接合件10之中央部位。在本實施例中，該接合件10之第二部12中央部位具有一標示孔121，用以便於組裝人員檢視該輪圈半成品20之二端是否對接於該接合件10之中央部位。Referring to FIG. 1 , FIG. 3 and FIG. 4 , when the joint member 10 is used on the rim semi-finished product 20 , the first portion 11 , the second portion 12 , the third portion 13 , and the fourth portion of the joint member 10 are used . The portion 14 corresponds to the outer side portion 22, the inner side portion 23 and the two side portions 24 of the rim engaging member 10, respectively, and the two ends thereof are respectively inserted into the rim semi-finished product 20 from the two openings 21, so that the engaging member 10 is The first portion 11 to the fourth portion 14 respectively face the outer side portion 22, the inner side portion 23, and the two side portions 24 of the rim semi-finished product 20, and are attached to the inner walls of the respective portions 22, 23, 24. In the process of inserting the engaging member 10 into the rim semi-finished product 20, the depth at which the engaging member 10 is inserted into the two ends of the rim semi-finished product 20 is maintained as much as possible, that is, the two ends of the rim semi-finished product 20 are opposed to each other. The ground is butted to the central portion of the joint member 10. In the embodiment, the central portion of the second portion 12 of the engaging member 10 has a marking hole 121 for the assembler to check whether the two ends of the rim semi-finished product 20 are butted against the central portion of the engaging member 10.
在將該接合件10塞設入該輪圈半成品20之過程中，隨著該接合件10深入該輪圈半成品20中，該輪圈半成品20的彎弧狀內壁會逐漸地壓迫該接合件10之相對部位。在本實施例中，該輪圈半成品20之外側部22內壁逐漸壓迫該接合件10之第一部11，使該第一部11受壓迫之部位擠壓著該第三部13及第四部14之相對應部位。此時，由於該第三、四部13、14上之切槽15的設計，使得該第一部11受壓迫之部位及該第三部13及第四部14的相對應部位可產生朝向該等切槽15之變形，以配合該輪圈半成品20之內壁形狀，使該接合件10緊密地塞設於該輪圈半成品20中。During the insertion of the engaging member 10 into the rim semi-finished product 20, as the engaging member 10 penetrates into the rim semi-finished product 20, the curved inner wall of the rim semi-finished product 20 gradually presses the engaging member. 10 relative parts. In this embodiment, the inner wall of the outer side portion 22 of the rim semi-finished product 20 gradually presses the first portion 11 of the engaging member 10, so that the pressed portion of the first portion 11 presses the third portion 13 and the fourth portion. The corresponding part of the part 14. At this time, due to the design of the slits 15 on the third and fourth portions 13, 14, the portion where the first portion 11 is pressed and the corresponding portion of the third portion 13 and the fourth portion 14 can be oriented toward the same. The deformation of the groove 15 is adapted to match the shape of the inner wall of the rim semi-finished product 20, so that the joint member 10 is tightly inserted into the rim semi-finished product 20.
另外，由於加工精度上的問題，該輪圈半成品20之管壁厚度如圖5所示，或有厚薄不均之現象，因此，位於該接合件10塞入該輪圈半成品20中的過程中，該第三部13或第四部14受厚管壁處壓迫時，可連同第一部11或 該第二部12的相對應部位產生朝向位於該第一部11或該第二部12上之切槽15產生變形，使該接合件10順利地被塞入該輪圈半成品20中。In addition, due to the problem of processing accuracy, the wall thickness of the rim semi-finished product 20 is as shown in FIG. 5, or there is a phenomenon of uneven thickness, and therefore, in the process of inserting the joint member 10 into the rim semi-finished product 20 When the third portion 13 or the fourth portion 14 is pressed by the thick tube wall, it may be combined with the first portion 11 or The corresponding portion of the second portion 12 is deformed toward the slit 15 located on the first portion 11 or the second portion 12, so that the engaging member 10 is smoothly inserted into the rim semi-finished product 20.
一般而言，該輪圈半成品20的彎曲量遠大於其 管壁之厚度變化量，所以該接合件10塞入該輪圈半成品20中時，該輪圈接合件10對應於該輪圈半成品20外側部22之部位所產生之變形量，會大於對應於該兩側部24之部位的變形量。因此，本實施例之接合件10，其位於該第三部13及該第四部14上的切槽15的長度，係大於位於該第一部11及該第二部12上的切槽15的長度。In general, the rim semi-finished product 20 has a much larger amount of bending than it The thickness of the pipe wall varies, so when the joint member 10 is inserted into the rim semi-finished product 20, the amount of deformation of the rim engaging member 10 corresponding to the portion of the outer portion 22 of the rim semi-finished product 20 may be greater than The amount of deformation of the portion of the both side portions 24. Therefore, the length of the slot 15 of the engaging member 10 of the present embodiment on the third portion 13 and the fourth portion 14 is greater than the slot 15 located on the first portion 11 and the second portion 12. length.
由於該接合件10呈直條狀，所以在塞入該輪圈半成品20中時，與該輪圈半成品20之彎弧狀內壁產生干涉，且加上該等切槽15之設置，使該接合件10隨著該輪圈半成品20之彎弧狀內壁產生變形，而與該輪圈半成品20間形成緊配合，而能更有效地結合該輪圈半成品20之兩端。藉由該接合件10之上述設計，該接合件10可免去用以配合該輪圈半成品20之內壁形狀之彎折加工程序，可節省加工成本，且不會產生該接合件10之彎幅與該輪圈半成品20之彎幅不一致之情事。再者，該接合件10因為該等切槽15之設置，而在塞入該輪圈半成品20之過程中時隨著該輪圈半成品20之內壁形狀變形，因此，即使該接合件10之外輪廓尺寸與該輪圈半成品20之內壁尺寸間具有一定的誤差，也不會影響該接合件10與該輪圈半成品20之間的結合緊迫度，所以，該接合件10在生產上可以具有較大之容許公差。Since the engaging member 10 has a straight strip shape, when inserted into the rim semi-finished product 20, interference occurs with the curved inner wall of the rim semi-finished product 20, and the setting of the slits 15 is added to The engaging member 10 is deformed along with the curved inner wall of the rim semi-finished product 20 to form a tight fit with the rim semi-finished product 20, so that both ends of the rim semi-finished product 20 can be more effectively combined. By the above design of the joint member 10, the joint member 10 can eliminate the bending process for matching the shape of the inner wall of the rim semi-finished product 20, thereby saving processing cost and not causing the bend of the joint member 10. The width of the web is inconsistent with the bend of the semi-finished product 20 of the rim. Moreover, the joint member 10 is deformed along with the shape of the inner wall of the rim semi-finished product 20 during the process of inserting the rim semi-finished product 20 due to the arrangement of the slits 15, so even if the joint member 10 is There is a certain error between the outer contour size and the inner wall dimension of the rim semi-finished product 20, and does not affect the bonding urgency between the joint member 10 and the rim semi-finished product 20, so the joint member 10 can be produced in production. Has a large tolerance.
本創作之接合件10除了圖1~圖5所示之實施態樣之外，亦可為其它具有相同功效之實施形態。請參閱圖6~圖8，本創作另一較佳實施例之接合件30亦為一鋁擠型管件，同樣具有一第一部31、一第二部32、一第三部 33以及一第四部34，且在該接合件30塞設於相同於第一實施例所示之輪圈半成品20中時，該第一部31至該第四部34同樣地分別面向且貼接於該輪圈半成品20之外側部22、內側部23以及二側部24之內壁。In addition to the embodiment shown in FIGS. 1 to 5, the engaging member 10 of the present invention may be other embodiments having the same effect. Referring to FIG. 6 to FIG. 8 , the joint member 30 of another preferred embodiment of the present invention is also an aluminum extruded tubular member, which also has a first portion 31 , a second portion 32 , and a third portion . 33 and a fourth portion 34, and when the engaging member 30 is plugged in the same rim semi-finished product 20 as shown in the first embodiment, the first portion 31 to the fourth portion 34 are equally facing and attached It is connected to the outer side wall 22, the inner side portion 23 and the inner wall of the two side portions 24 of the rim semi-finished product 20.
與第一實施例相同地，該接合件30具有一手段，用以使該接合件30緊密地自該輪圈半成品20的該二開口21塞設入該輪圈半成品20中者。在本實施例中，該手段為該第一部31、第二部32、第三部33及該第四部34之外上所設置之各一凹槽35，且各凹槽35沿該接合件30軸向貫通所在之部的兩端。As with the first embodiment, the engaging member 30 has a means for the engaging member 30 to be tightly inserted into the rim semi-finished product 20 from the two openings 21 of the rim semi-finished product 20. In this embodiment, the means is a groove 35 provided on the outside of the first portion 31, the second portion 32, the third portion 33 and the fourth portion 34, and each groove 35 is along the joint The member 30 axially penetrates both ends of the portion where it is located.
請參閱圖6及圖7，在將該接合件30塞設入該輪圈半成品20之過程中，隨著該接合件30深入該輪圈半成品20中，該輪圈半成品20的彎弧狀內壁會逐漸地壓迫該接合件30之相對部位。在本實施例中，該輪圈半成品20之外側部22內壁逐漸壓迫該接合件30之第一部31，使該第一部31受壓迫之部位擠壓著該第三部33及第四部34之相對應部位。此時，由於該第三、四部33、34上之凹槽35的設計，使得該第一部31受壓迫之部位及該第三部33及第四部34的相對應部位可產生朝向該等凹槽35相對部位之變形，以配合該輪圈半成品20之內壁形狀，使該接合件30緊密地塞設於該輪圈半成品20中。Referring to FIG. 6 and FIG. 7, in the process of inserting the joint member 30 into the rim semi-finished product 20, the rim intermediate product 20 is curved in the arc as the joint member 30 penetrates into the rim semi-finished product 20. The wall gradually compresses the opposing portions of the engaging member 30. In this embodiment, the inner wall of the outer side portion 22 of the rim semi-finished product 20 gradually presses the first portion 31 of the engaging member 30, so that the pressed portion of the first portion 31 presses the third portion 33 and the fourth portion. The corresponding part of the part 34. At this time, due to the design of the groove 35 on the third and fourth portions 33, 34, the portion where the first portion 31 is pressed and the corresponding portion of the third portion 33 and the fourth portion 34 can be oriented toward the same The opposite portion of the groove 35 is deformed to match the shape of the inner wall of the rim semi-finished product 20, so that the engaging member 30 is tightly inserted into the rim semi-finished product 20.
另外，該輪圈半成品20之兩端處管壁或有厚薄不均之現象，因此，位於該接合件30塞入該輪圈半成品20中的過程中，該第三部33或第四部34受厚管壁處壓迫時，可連同第一部31或該第二部32的相對應部位產生朝向位於該第一部31或該第二部32上之凹槽35產生變形，使該接合件30順利地被塞入該輪圈半成品20中。In addition, the pipe wall at both ends of the rim semi-finished product 20 may have uneven thickness, and therefore, the third portion 33 or the fourth portion 34 is located during the insertion of the engaging member 30 into the rim semi-finished product 20. When pressed by the thick tube wall, the corresponding portion of the first portion 31 or the second portion 32 may be deformed toward the groove 35 located on the first portion 31 or the second portion 32, so that the joint member 30 is smoothly inserted into the rim semi-finished product 20.
由上述可知，本實施例之接合件30，其用以緊 密地結合於輪圈半成品中之手段所採用之結構雖與第一實施例者不同，但同樣都能達成緊迫地結合於該輪圈半成品20兩端的效果，且同樣地在生產上可以具有較大之容許公差。另外，本實施例之接合件30不但可免除折彎加工程序，更由於該等凹槽35係於擠型加上時已經完成，而不需藉由其他加工程序製成，可進一步地降低製造成本。It can be seen from the above that the joint member 30 of the embodiment is used for tightening The structure adopted in the means of densely bonding to the rim semi-finished product is different from that of the first embodiment, but the effect of pressing tightly on both ends of the rim semi-finished product 20 can also be achieved, and similarly, it can be produced in comparison. Large tolerances. In addition, the joint member 30 of the embodiment can not only eliminate the bending process, but also further reduce the manufacturing because the grooves 35 are completed when the extrusion type is added, without being processed by other processing programs. cost.
