具減震功能之行李箱腳輪Shockproof trunk casters

本創作係涉及一種行李箱腳輪，特別是指一種減震效果佳之創新結構型態揭示者。This creation relates to a trunk caster, and in particular to an innovative structural type revealer with good shock absorption.

按，一般行李箱的底座皆樞設有腳輪以便於拖行移動，而習知行李箱之腳輪為大眾所熟知，該腳輪係藉由輪座直接組設定位於行李箱底座，由於行李箱之腳輪僅能採用實心之小規格輪體以不占用空間，因此，該腳輪本身之避震緩衝效果可說微乎其微，這不僅在拖行於較粗糙路面時，易造成使用者握持感之麻震不適以及腳輪滾動時較大之噪音現象，且對於行李箱內部較不耐震動之精密物品而言，亦較容易造成損壞者。Press, the base of the general luggage box is pivoted with casters for towing movement, and the casters of the conventional luggage are well known to the public. The casters are set directly on the base of the luggage by the wheel base, because the casters of the luggage Only the solid small-sized wheel body can be used to take up no space. Therefore, the shock absorber cushioning effect of the caster itself can be said to be minimal, which is not only easy to cause the user to feel the shock when dragging on the rough road surface. And the greater noise phenomenon when the casters are rolling, and it is also more likely to cause damage to the delicate items inside the luggage compartment that are less resistant to vibration.

於是便開始有行李箱業者開發出具減震功能之行李箱腳輪。如 鈞局於2003年7月1日所核准公告之第540338號新型專利案「行李箱輪座之避震結構」，其主要係利用設置於輪軸兩側之彈簧槽與裝設於該彈簧槽中的彈簧來提供減震的功能。然而，行李箱輪座先天上本來就有體積的限制，而又要一次裝設兩彈簧反倒是無形間限制了彈簧的尺寸與規格，比方說彈簧的外徑與線徑皆必需相對縮小，方能順利安裝於相對應的彈簧槽中，彈簧往往因本身彈力度足，因而所能提供的減震效果有限。且當行李箱總重超過一定限度時，因彈簧已經被預先壓縮了一段距離，使得彈簧已無足夠的壓縮空間，大幅降低了彈簧所能提供的減震效果，甚至因過度壓縮而無法適時提供減震的功效。再者，前述習用行李箱腳輪必需在有限空間安裝兩彈簧以及與該兩彈簧互相連動之輪軸，有相當的組裝難度，必然會提高行李箱腳輪之生產成本。As a result, the luggage industry began to develop the trunk casters with shock absorption. For example, the new patent case No. 540338, approved by the Bureau of the People's Republic of China on July 1, 2003, "the suspension structure of the trunk wheel seat" is mainly installed in the spring groove by spring grooves provided on both sides of the axle. The spring is used to provide shock absorption. However, the trunk wheel hub inherently has a volume limitation, and it is necessary to install two springs at a time. The invisible limit limits the size and specifications of the spring. For example, the outer diameter and the wire diameter of the spring must be relatively reduced. It can be installed smoothly in the corresponding spring groove, and the spring tends to have sufficient shock absorption effect due to its own elastic force. And when the total weight of the trunk exceeds a certain limit, since the spring has been pre-compressed for a certain distance, the spring has no sufficient compression space, which greatly reduces the shock absorption effect that the spring can provide, and even cannot be timely provided due to excessive compression. The effect of shock absorption. Furthermore, the aforementioned conventional trunk casters must be equipped with two springs in a limited space and an axle that is interlocked with the two springs, which has considerable assembly difficulty and inevitably increases the production cost of the trunk casters.

是以，針對上述習知結構所存在之問題點，如何開發一種更具理想實用性之創新結構，實使用者所企盼，亦係相關業者須努力研發突破之目標及方向。Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

The degree of preloading of the spring 20, and the degree of preloading of the spring 20 is proportional to the total weight of the trunk when it is used, that is, the heavier the total weight of the trunk when used, the tighter the preload of the spring 20. Referring to Figures 3 and 7, when the user drags the trunk with the roller 50 on the ground and slightly protrudes when the moving surface is encountered, the roller 50 sequentially compresses the spring through the wheel base 40 and the pressure plate 30. 20, and the use of the compressible characteristics of the spring 20 to provide the shock absorber effect of the luggage, in addition to protecting the contents contained in the luggage, and because of the vibration suppression relationship, the user does not make the hand by dragging the luggage Produce the discomfort of the shock. Furthermore, the spring 20 of the present invention has a single design and is accommodated in the cylindrical receiving hole 12. Therefore, the trunk casters of the same specification can appropriately enlarge the spring 20 by the structural design of the creation mount 10. Specifications (such as outside diameter and wire diameter), combined with the aforementioned preload adjustments, can extend the weight bearing range of the creation, which is to expand the applicability of the creation and the different purpose or volume of luggage. The sleeve 43 fixed in the small diameter section 411 of the through hole 41, in addition to the structural strength of the reinforcing wheel base 40 itself, can be provided with a bolt 44 when the wheel base 40 rotates or moves radially relative to the mounting seat 10. Smooth operation and reduced noise.
