Embodiment

Offer is described below to enable those skilled in the art to manufacture and use many examples disclosed herein, institute Stating many examples includes the optimal mode for many utility models for being contemplated for carrying out limiting in each side such as the disclosure.This public affairs That opens is permitted many various shaftless wheels included on wheeled luggage of retrofiting, and shaftless wheel includes dust labyrinth part to prevent dust Enter with chip inside shaftless wheel and to keep the operation of shaftless wheel.

In many aspects, hereinafter, term " the shaftless wheel in labyrinth " or " the shaftless wheel with dust labyrinth part " can refer to Be such wheel：The wheel can mechanically be attached to the attachment plane on luggage case, but be the absence of wheel and can rotate on it Conventional center axis, wherein, wheel plane parallel to the attachment plane on (or being roughly parallel to) luggage case.

Referring now to Fig. 1, Fig. 1 depicts the exploded view of shaftless dust labyrinth wheel 100.Wheel 100 can include outer rim 15, Ground engagement part 10 may be mounted on the outer rim 15.In many aspects, ground engagement part 10 can be tire, polymer Deng.The roller 20 that can be rotatably set in ball rack 30 can be held against outer rim 15 by interior wheel rim 40, to allow foreign steamer Rim 15 and ground engagement part 10 are rotated relative to interior wheel rim 40.Sidepiece covering 50 can be configured to be fixed to interior wheel rim 40.Side Portion's covering 50 can be also configured to be fixed to outer rim 15.In many aspects, ground engagement part 10 can be tire, polymer Deng.

Referring now to Fig. 2, Fig. 2 depicts the example cross section of shaftless dust labyrinth wheel 100a, the shaftless dust labyrinth Wheel 100a includes dust labyrinth configuration 25, and the inside which can be shown as reducing shaftless wheel is run into enough The dust of amount or the tendency of chip, the dust or chip of sufficient amount may interrupt the normal operating of shaftless wheel 100a.Dust fan Palace portion 25 has two sections 60,70.Section 60 can be located inside portion (that is, the side where with sidepiece covering 50 of wheel 100 The opposite sidepiece in portion) place, and section 60 can be configured to be fixed to the wall of the formation storage room 210 (Figure 14) of luggage case 200 (Fig. 3).

Section 60 can be engaged with ground the cooperation of the extension 10aa of part 10a to limit by interior wheel rim 40, the extension Portion 10aa can extend beyond outer rim 15.Section 70 at the outside portion of wheel 100a can pass through sidepiece covering 50 Cooperation between a part, a part for outer rim 15, a part for a part for ball rack 30 and interior wheel rim 40 limits.Portion 60,70 and extension 10aa of section can prevent or reduce penetrating for dust or chip, and dust and penetrating for chip will hinder roller 20 and rolling movement of the ball rack 30 between interior wheel rim 40 and outer rim 15.In many aspects, ground engagement part 10a can be Tire, polymer etc..

Referring now to Fig. 3, Fig. 3 depicts the another exemplary sectional view of the shaftless wheel 100b in labyrinth according to the disclosure.Nothing Axis wheel 100b can be included with bilateral dust labyrinth part similar with section 70 section 60a.Section 60a can be located at wheel Inside portion (that is, the sidepiece opposite with the sidepiece where sidepiece covering 50) place of 100b, and section 60a can be fixed or connected It is connected to the wall (Fig. 3) of the formation storage room 210 (Figure 14) of luggage case 200.Section 60a can by the part of interior wheel rim 40 with it is outer Cooperation between the extension 15aa of wheel rim 15a limits.Wherein extension 10aa unlike shown in Fig. 2 can be by ground engagement Part 10a forms (or extension for ground engagement part 10a) like that, and the extension 15aa in Fig. 3 can be by the material of outer rim 15a Material is formed (or being the extension of the material of outer rim 15a).As wheel 100a, the section 70 taken turns in 100b can be located at labyrinth At the outside portion of shaftless wheel 100b.Taking turns section 70 in 100b can be by the part of sidepiece covering 50, outer rim 15a Cooperation between a part, a part for a part for ball rack 30 and interior wheel rim 40 limits.Section 60a, 70 and extension 15aa can prevent or reduce penetrating for dust or chip, and dust or penetrating for chip will hinder roller 20 and ball rack 30 to exist Rolling movement between interior wheel rim 40 and outer rim 15a.

Referring now to Fig. 4, Fig. 4 depicts exemplary sidepiece covering 50a, and sidepiece covering 50a can be fastened to Shaftless wheel 100,100a (Fig. 2), 100b (Fig. 3).Sidepiece covering 50a can be configured with least one elastic card fastener 55, institute State on the end difference 45 that at least one elastic card fastener 55 can be fixed on the surface of interior wheel rim 40.In many aspects, Sidepiece covering 50a can also be fastened to outer rim 15.

Referring now to Fig. 5, Fig. 5 is depicted with the shaftless wheeled luggage for taking turns 100,100a (Fig. 2), 100b (Fig. 3) 200.Wheeled luggage 200 can define 210 case lid 220 of storage room, which can open so that storage room 210 is sudden and violent Reveal and the entrance (Figure 14) into storage room 210 is provided.Case lid 220 can also be closed and locked to prevent from entering storage room 210. At two opposite sides of storage room 210, the wall of luggage case 200 can limit side pocket 240, shaftless wheel 100,100a, 100b can be installed in side pocket 240 for the rotation in side pocket 240.Side pocket 240 can be relative to side wall 225 (towards the inside of case 200) recessed, to allow the part of recess 240 to be partially rotated to recess in ground engagement part 10,10a These parts of ground engagement part 10,10a are hidden from the visual field when middle near 240.In the configuration, user is grasping The top of tire 10,10a can not be observed when luggage case 200 is rolled in work.

Referring now to Fig. 6 and Fig. 7, Fig. 6 and Fig. 7 depict the mechanism with flexible elements that wheeled luggage is drawn in a manner of groups of, The mechanism with flexible elements includes flexible belt 230.Flexible belt 230 can be disposed from port 235 and can be retracted into port 235.Machine Structure 237 can be configured to dispose flexible belt 230 from port 235 at the wall of storage room 210 and be retracted into flexible belt 230 In port 235.
