Description

A kind of case and bag that have carriage

Technical field

The utility model relates to a kind of case and bag, and particularly a kind of carriage that has can conveniently be gone up case and bag downstairs.

Background technology

Along with the economic development social progress, people's trip contacts are more and more frequent, and personal belongings are absolutely necessary again, and laborsaving case and bag easily just become people's first-selection.And most of case and bag in the market can only on the way tow, and for stair activity, step, can only take on anti-portable.And heavy luggage all is burden concerning anyone, old man particularly, and the woman is weak invalid to be difficult to alone tote box especially and to wrap downstairs.

In addition, also having some case and bag to make some improvement can go downstairs people easily in tow on the case and bag." at Chinese patent notification number CN200520036057.3, the day for announcing is on December 6th, 2006, name be called disclose in the patent of ' convenience on downstairs case and bag ' a kind of stair activity do not need to take on resist portable, the case and bag that can tow." this patent solved more above-mentioned problems, make people on heavy luggage, can tow case and bag downstairs the time, and need not tax one's mind and strength so.But have shortcoming equally, because there is difference in height in every rank staircase, case and bag tow in the above and are jolted more seriously, and the time has been grown and has been easy to case and bag are caused damage, and carriage also is damaged easily, thereby loses more than gain.

The utility model content

In order to address the above problem, the utility model has been announced a kind of case and bag that have carriage.

The utility model is by the following technical solutions: comprise the case and bag main body, roller, pull bar, carriage, it is characterized in that, described carriage is fixed in case and bag main body back, form by slipper and shock absorbing part, slipper is fixed on above the shock absorbing part and along the case and bag thickness direction and exceeds roller, and shock absorbing part and slipper have at least one to support interface point, shock absorbing part is made of elastomeric material or device, carriage is the rotatable case and bag back of being fixed in of an end wherein, the other end is fixed by a scalable connecting rod, and carriage bottom surface length is not less than 250mm.

Adopt case and bag of the present utility model, in last going downstairs, need not take on the anti-very big strength of portable cost again, and can directly tow the case and bag stair activity.Shock absorbing part in the utility model has better played protective effect to case and bag simultaneously.

The specific embodiment

For the easier quilt of the utility model is understood, the utility model is done more detailed description below in conjunction with accompanying drawing.

Consult Fig. 1, Figure 10, Figure 11, Figure 14, Figure 15, a kind of case and bag that have carriage, comprise case and bag main body 1, roller 4, pull bar 2, carriage 3, it is characterized in that, described carriage 3 is fixed in case and bag main body 1 back, form by slipper 5 and shock absorbing part 6, slipper 5 is fixed on above the shock absorbing part 6 and along the case and bag thickness direction and exceeds roller 4, and shock absorbing part 6 has at least one to support interface point with slipper 5, shock absorbing part 6 is made of elastomeric material or device, carriage 3 is the rotatable case and bag back of being fixed in of an end wherein, and the other end is fixed by scalable connecting rod 8.

Consult Fig. 1, slipper 5 can be roller structure.

Consult Fig. 2, slipper 5 can be chain structure.

Consult Fig. 3, slipper 5 can be caterpillar belt structure.

Consult Fig. 4, slipper 5 can be rail structure.

Consult Fig. 6, Fig. 7, Fig. 8, Fig. 9, carriage 3 can be one or two, is fixed on case and bag main body both sides, 1 back or centre, and carriage 3 can be linear, and variforms such as arc determine according to the actual requirements.

Consult Figure 12, Figure 13, when towing the upper and lower building of case and bag, because height of least differs 150mm between the stair of every rank, so for carriage 3 can be stuck between the stair, carriage 3 bottom surface length are not less than 250mm.

Consult Figure 10, Figure 13, when towing the upper and lower building of case and bag, because the horizontal level that pull bar 2 is in is very low with respect to people's hand, people in use, stoop waist and just can haul pull bar the 2nd upper and lower buildings if stature, takes a lot of strength possibly than higher, very inconvenient.So carriage 3 is provided with one and heightens function in the utility model, realize by telescopic connecting rod 8.Near rotatable case and bag main body 1 back of being fixed in of an end of roller 4, the other end is fixing by connecting rod 8.During use, connecting rod 8 elongation propped and fixing, carriage 3 just can be heightened, and the user just need not require great effort very much again like this bends over to contact pull bar 2, tows the upper and lower building of case and bag.When not using, connecting rod 8 is shunk, just can not increase case and bag main body 1 volume.Simultaneously, according to actual conditions, telescopic connecting rod 8 also can carry shock-absorbing function, and connecting rod 8 can be decompression devices such as hydraulic stem.

Consult Figure 11, connecting rod 8 also has a kind of embodiment, and is fixing by connecting rod 8 near roller 4 one ends away from rotatable case and bag main body 1 back that is fixed on of an end of roller 4, and sets up a roller on carriage 3.During use, connecting rod 8 elongations are propped and fixed.Like this, carriage 3 just can play a firm effect.

Consult Figure 12, Figure 13, Figure 14, Figure 15, when towing the upper and lower building of case and bag, owing to have difference in height between the stair, when towing, case and bag can be jolted unavoidably.If the time one is long, there is not safeguard measure, case and bag and carriage 3 all are easy to be damaged.The utility model is provided with shock absorbing part 6 in carriage 3, the damping effect of shock absorbing part 6 is realized by spring 7.When towing the upper and lower building of case and bag, spring 7 can be alleviated the impulse force that tows the generation of process moderately gusty air greatly, thereby case and bag and carriage 3 are protected.Simultaneously, can also replace by air bag, elasticity iron plate or elastic materials such as hydraulic stem or rubber like elastomer according to actual conditions spring 7.

Consult Figure 16, Figure 17, Figure 18, Figure 19, Figure 20, when slipper 5 was roller, the arrangement mode of roller can be single arrangement or double arrangement arranged side by side or double roller and is staggered etc., selects arrangement mode as the case may be.

Consult Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, carriage 3 is fixed on the back of case and bag main body 1, can be the groove that a corresponding carriage 3 is set at the back of case and bag main body 1, and carriage 3 is fixed therein, also can not offer groove, be directly installed on the casing or pull bar 2 on.Decide on actual conditions concrete fixing means and position.When carriage 3 is convex, be provided with spring leaf 9 at case and bag main body 1 back, carriage 3 is fixed on the spring leaf 9.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
