Description

Roller devices

The present invention relates to suitcase and carry bag and traveling bag similar, relate in particular to the tourelle of being convenient to carry above-mentioned bag with it.

For the traveller is run on the circular passage on airport easily with their bag, people had once carried out a lot of trials.Wherein, the various dollies that castor is housed have obtained extensive use, they are included in the folding trolley that can be folded into small and exquisite object after the standing handcart in airport or other transportation place, the usefulness that the traveller carries, also comprise commercially available, be equipped with the bottom side and the suitcase of casing all-in-one-piece roller

Though it is extremely general that above-mentioned these ways are used, and all can not solve existing issue satisfactorily.Owing to enable dolly is folded up when using in the travelling and in the gap of using in succession but its size is still too big, be still a pretty troublesome thing so the folding dolly of this class uses.

Usually the roller diameter of institute's insert is less, therefore, even there is minimum barrier also can experience on the floor, even causes the chest stand or topples over.In addition, roller size is little just must the installing four wheels.If only adorn two bigger wheels in a side of chest, just need a telescopic handle, this will make box construction illustrated more complicated certainly, and price is more expensive.

The dismountable chest of castor or roller, promptly the chest that wheel can be removed singly in time spent not also is known, but the wheel of unloading down may be misplaced or be lost.

Task of the present invention is to overcome above-mentioned defective and other defective of suitcase roller devices.

The invention provides a kind of small-sized roller devices of being convenient to mobile suitcase and similar weight, it can be contained in the chest bottom during use, the time spent can not unloaded it again.This device comprises: the block-shape shell of a flat-top, and a pair of roller that is contained on the housing, and an endless belt that has clasp with being separated by, this endless belt is installed on the housing, and energy Stretch is tightly around chest, so that removably housing is bound in the chest bottom.

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, by to these only as an example descriptions of embodiment, people can more clearly understand the present invention, also can more fully estimate advantage of the present invention.Wherein:

Fig. 1 is the stereogram with roller devices of essential characteristic of the present invention;

Fig. 2 is the local longitudinal sectional drawing of roller devices shown in Figure 1;

The schematic diagram that Fig. 3 uses for roller devices;

Fig. 4 is the end-view of the suitcase that has roller devices shown in Figure 3;

Fig. 5 is the schematic diagram according to the another kind of occupation mode of device of the present invention;

Fig. 6 is the fixing schematic diagram of roller devices of different outer shaped objects;

Fig. 7 is a kind of remodeling of device shown in Figure 1;

The cover piece of Fig. 8 presentation graphs 7 shown devices;

Fig. 9 is a kind of remodeling of cover piece shown in Figure 8.

Referring to Fig. 1 and Fig. 2, represent this roller devices with label 10 usually, it is made of the prismatic housing 12 of a rectangle, and this housing is preferably formed by plastic injected die.Housing is made up of as part 14 and 16 opposed blocks a pair of, and above-mentioned block is used for laying a pair of label 18 and the 20 represented rollers used, and therefore, part 14 defines a cavity 22, so that the axle 24 of roller 18 is installed; The part 16 that is positioned at the other end of housing 12 also has identical structure.

The sidewall 26 of housing 12 and 28 defines a space 32 with diapire 30, and the size in space 32 is suitable for depositing the belt 34 of the bracelet ring 36 that is folded.For convenience's sake, have slit 30a on the diapire 30,30b, 30c and 30d, belt 34 passes from above-mentioned slit, rather than with as riveted joint or bonding and so on addition thereto fix.

Four dogs 40 are established at the top that is preferably in space 32 openings, so that form stopping means, make and the belt 34 that folds can be put into space 32 without roller devices the time.

In addition, also have shallow grooves or recess 42 in the both sides of housing, as for why having this class groove below will further specify.

As shown in Figure 3 and Figure 4, roller devices 10 is fixed on the diapire of suitcase 50 by means of belt 34 during use, tightens by clasp 36 then.Below by (if having reinforce belt), belt 34 preferably has a handle 34b to the extension 34a of belt from the reinforce belt 52 and 54 of chest 50, and by means of this handle, the user can and walk in tow with the chest pull-up.

Clearly, it is shown in Figure 1 that belt 34 can pass recess 42(), therefore can not influence the upper surface and direct and firm the contacting in the bottom surface of chest 50 of housing 12.

As shown in Figure 5, as long as see fit, also can adopt a pair of roller devices 10 easily.

Fig. 6 shows a roller devices that is made of the housing 12 of having deposited belt 34, and in this embodiment, endless belt is made by rubber, and the effect and the handle portion 34a of solid thin cord 60 are similar.

Time spent roller devices 10 can not separate with the article that will carry such as suitcase, bag or other weights fully, and for convenience's sake, the belt band can be folded in the storage area 32.

Because the size of roller devices 10 is little, therefore be easy to harvesting, and can not appear at folding trolley or situation that wheel is pulled down in any trouble and the inconvenience that are run into.

It should be noted that wheel 18 and 20 diameter can be more much bigger than the diameter that is contained in roller on all kinds of suitcases or castor, chest can move under the condition with higher of distance ground, thereby easier rolling and roll more steadily, especially on uneven or coarse ground, roll and get up to want easily and much steady.

In the embodiment shown in fig. 7, tourelle 110 has a lid 170, and this lid is close to the top of the parking space 132 of belt by means of rubbing action or snap, and does not have dog 40(Fig. 1).

The middle body width of lid 170 is narrower, is provided with one or two at least for the breach 172 of pulling out usefulness at middle body.

Belt 134 can contact with lid 170 as Fig. 8 or mode shown in Figure 9.

Can also establish a spill window 174 to be used to insert marker slip, advertisement, gray trade (brand) name, exabyte and address or the like.

Obviously, this cover piece also is suitable for doing handle with (seeing 34b among Fig. 3).

Can predict, this roller devices realize easily producing in batches and cost extremely low, even can also become airline or travel agency as tendentious present article.

Those of ordinary skills under the situation that does not exceed design scope of the present invention, are easy to above-mentioned technology contents is made all changes, modification and remodeling in the qualification of appending claims.
