可調整長度的土除腳Adjustable length soil removal foot

本新型是有關於一種自行車配件，特別是指一種連接於車架與土除間的土除腳。The present invention relates to a bicycle accessory, and more particularly to a soil removing foot connected to a frame and a soil removal room.

一般自行車的土除是透過土除腳而安裝於自行車的車架並位於車輪的上方，用以遮擋車輪轉動時所帶起灰塵泥水。由於自行車可能換裝不同尺寸大小的車輪，或土除與車架間不同的配置態樣需求，所以土除腳的長度須要可以伸縮調整來適應不同的安裝需求。In general, the soil of the bicycle is installed on the frame of the bicycle through the soil and is placed above the wheel to block the dust and water generated when the wheel rotates. Since the bicycle may be replaced with wheels of different sizes or different configurations of the soil and the frame, the length of the soil removal foot needs to be telescopically adjusted to suit different installation requirements.

如先前技術文獻GB 2492842A專利案所提出的一種可伸縮調整長度的土除腳，其包含一第一元件及一可沿一長度方向往復滑設於該第一元件的第二元件。該第一元件具有一沿該長度方向延伸的齒段，該第二元件具有一可卡制限位於該齒段的卡止部，藉由該卡止部與該齒段相配合，可限制該第一元件不能相對該第二元件沿該長度方向移動。上述土除腳透過拉扯或推擠該第一元件及該第二元件，迫使該卡止部迫壓該齒段而變形滑過該齒段的凸齒，從而用以伸縮調整該土除腳的長度。A telescopically adjustable length soil removal foot as disclosed in the prior art document GB 2492842A, comprising a first component and a second component reciprocally slidable along the length of the first component. The first component has a tooth segment extending along the length direction, and the second component has a locking portion that is constrained to be located in the tooth segment, and the locking portion is matched with the tooth segment to limit the first portion An element cannot move relative to the second element along the length. The soil removing leg presses or pushes the first component and the second component, forcing the locking portion to press the tooth segment to deform and slide the convex tooth of the tooth segment, thereby expanding and adjusting the soil removing foot. length.

上述土除腳的該第一元件的該齒段及該第二元件的該卡止部的卡嵌深度設計較淺，以讓該卡制部迫壓變形滑過該齒段的凸齒所需的變形量較小，從而能較不費力地操作該土除腳進行調整長度，相反地，則會使得該卡制部卡制限位於該齒段的凸齒間的限位效果不好，在土除的重力下壓再加上震動外力下，容易致使該第一元件相對該第二元件滑移，從而無法有效將土除支撐於原先設置位置。再者，在伸縮調整長度時，該卡止部須變形扭曲滑過該齒段的多數凸齒，如此頻繁多次的變形摩擦加速該卡止部斷裂或受損，從而失去固定限位效果，因此，上述土除腳仍有改進空間。The locking depth of the tooth segment of the first component of the soil removing foot and the locking portion of the second component is designed to be shallow, so that the clamping portion is required to be forced to deform and slide over the convex tooth of the tooth segment. The deformation amount is small, so that the soil removal foot can be operated with less effort to adjust the length, and conversely, the restriction of the engagement portion between the convex teeth of the tooth segment is not good, and the soil is not good. In addition to the gravity pressing and the external force of the vibration, the first element is easily slipped relative to the second element, so that the soil cannot be effectively supported in the original set position. Moreover, when the telescopic adjustment length is long, the locking portion has to be deformed and twisted and slid over the majority of the convex teeth of the tooth segment, so that the deformation friction repeatedly frequently accelerates the broken or damaged portion of the locking portion, thereby losing the fixed limit effect. Therefore, there is still room for improvement in the above-mentioned soil removal foot.

另外，先前技術文獻US 8172246B2專利案雖提出了無段伸縮調整土除腳長度的技術，但調整長度時需要額外工具進行操作，增加了安裝土除腳時的不便性。In addition, the prior art document US Pat. No. 8,172,246 B2 proposes a technique of adjusting the length of the soil by the stepless telescopic adjustment, but requires additional tools for operation when adjusting the length, which increases the inconvenience when installing the soil to remove the foot.

因此，本新型之目的，即在提供一種在使用上不需額外工具進行操作，且固定限位效果佳的可調整長度的土除腳。Therefore, the purpose of the present invention is to provide an adjustable length soil removing foot that does not require additional tools for operation and has a fixed limit effect.

於是，本新型可調整長度的土除腳包含一第一元件，及一第二元件。Thus, the novel adjustable length soil removing leg comprises a first component and a second component.
