Abstract

The utility model relates to an improved structure of a folding umbrella carriage which comprises front and rear supporting rods, handrails, back crossing supporting rods, base supporting rods, a front pedal, a brake plate, coupling elements and wheel devices, wherein, the upper end of each rear supporting rod is directly coupled with the front supporting rod, and the middle piece of each rear supporting rod is respectively coupled with two rear supporting rods and the base supporting rods via the coupling elements. Meanwhile, the handrails are also respectively coupled with the front supporting rods and the back crossing supporting rods via the coupling elements. Thus, the whole umbrella carriage can have a convenient folding function, and have the advantages of simpler components, quicker assembly and lower cost than a common folding umbrella carriage.

Description

Improved structure of folding carriages with umbrella

The invention belongs to the improvement of folding carriages with umbrella structure, particularly can be with the folding umbrella car of minimum coupling unit formation.

Folding carriages with umbrella framework commonly used has grab rail 3 as shown in Figure 4, forward and backward pole 1,2, and the end, intersect steady arm 82, and the back intersects steady arm 4, pitman 81, slipper 40 steps on 83, connection element 7, and wheel 9 before soft.Front support rod 1 is borrowed connection element 7 to engage grab rail 3 movable of formations and is stopped up, and steps on 83 before the preceding bottom of two front support rods connects.Because of back stay 2 also is connected on the grab rail 3 with connection element 7, making 1,2 of forward and backward poles more need link has pitman 81 as stiffener.Because before stepping on 83 is soft bodies, has no a sense of safety in the use.Aforementioned umbrella car has significant disadvantages in manufacturing and use:

1, the entire combination member is numerous and diverse, expends man-hour, increases cost;

2, the entire combination member is many, operates dumbly, uses not convenient;

3, integral rigidity is poor, has no a sense of safety.

The purpose of the invention is to improve folding carriages with umbrella unitary construction commonly used, and to propose a kind of member few for this reason, and integral rigidity is good, uses flexible operation, folding carriages with umbrella organization plan easily.

The feature of the invention is directly with its loose joint front support rod upper end, upper end with back stay, the end is intersected steady arm change two discrete end steady arms into, the front and back ends portion of steady arm is fixed in front running board both-end bottom surface respectively and borrows connection element to be connected in the back stay middle section at the bottom of two; Intersection steady arm bottom, back borrows connection element to be connected in the middle section of back stay.The invention scheme also adopts folding rigidity front running board to replace soft front running board, and folding front running board is to be connected by upside fin, downside fin and intermediate to constitute.

This improvement project reduces a pair of pitman than umbrella car commonly used, and replaces the software front running board with the front running board rolled over of rigidity, has reduced member, has strengthened integral rigidity again.

The embodiment of the invention is as shown in drawings:

Fig. 1 is the entire combination constructional drawing of a kind of embodiment of the invention, and wherein Figure 11 is an overall diagram, and Figure 12 is a ㄇ type connection element, and Figure 13 is a L type connection element;

Fig. 2 is the use application drawing of Fig. 1 composite construction;

Fig. 3 is the use application drawing of Fig. 1 composite construction;

Fig. 4 is a folding carriages with umbrella constructional drawing commonly used.

Explanation to shown by reference numeral:

1, front support rod, 2, back stay, 3, grab rail, 4, the back intersects steady arm, and 40, slipper, 5, end steady arm, 6, front running board, 60, upside fin, 61, the downside fin, 62, intermediate, 7, connection element, 81, pitman, 82, the end intersect steady arm, and 83, the software front running board, 9, wheel.

In conjunction with the accompanying drawings this improvement project is specified.

At first consult Fig. 1, this case includes forward and backward pole 1,2, grab rail 3, and back intersection steady arm 4, end steady arm 5, front running board 6, connection element 7 and wheel 9 constitute, wherein:

Front support rod 1 upper end connects grab rail 3 with connection element 7, but the bottom is connected with the wheel 9 of turn;

Back stay 2 upper ends connect front support rod 1, but the bottom is connected with the wheel 9 of turn;

Intersection steady arm 4 upper ends, back engage grab rails 3 with connection element 7, and the bottom is bonded on the stage casing of back stay 2 with connection element 7 and slipper 40;

Steady arm 5 leading sections in the end are fixed in front running board 6 bottoms, and rearward end then borrows connection element 7 to be connected in the stage casing of back stay 2;

Front running board 6 is connected between two front support rods, 1 front end, mainly is to be made of upside fin 60, downside fin 61 and intermediate 62 loose joints;

Connection element 7 is divided into U-shaped and L shaped body, links as each turning joint and uses.

During combination, borrow connection element 7 respectively at 3 of front support rod 1 and grab rails, grab rail 3 with after intersect between steady arm 4 upper ends, intersegmental in intersection steady arm 4 bottoms, back and the back stay 2, steady arm 5 rearward end in the end connect formation movable joint with back stay 2 stage casing intercropping, before inciting somebody to action then, back stay 1,2 upper ends handing-over riveting alive, and make front running board 6 getas be fixed in before two front support rods 1 between the bottom and slipper 40 is located at the back and is intersected steady arm 4 bottoms, again two end steady arms, 5 front ends are fixed in front running board 6 downside fins 62 lower ends, before at last each wheel 9 being assembled in respectively, back stay 1,2 bottoms, so far, the assembling of the umbrella car framework of this improvement project finishes.

During use, please consult the drawing of Fig. 1 to Fig. 3 again, when folding whole umbrella car, elder generation rises to the bait slipper 40 with tiptoe and both hands is held in grab rail 3 application of forces forward, at this moment, grab rail 3 will be axle center overlapping forward with connection element 7 places, and driving back intersection steady arm 4 is that the axle center is in company with overlapping by means of connection element 7 places also, and front running board 6 is passed by inside strength, make, downside fin 60,61 and 62 of intermediates change make two before, back stay 1,2 are able to more shape near folding, and when grab rail 3 is pushed when moving near level attitude this front and back pole 1,2 also is that axe movement forms horizontal collapse state as shown in Figure 3 with the connection place; When launching whole umbrella car, can just can reach and use according to the above-mentioned opposite sense application of force.

Make comparisons with umbrella car commonly used, this improvement project has following advantage:

1, whole member is few, and the combination of each element coupling position more is in harmony and is worked as, and can save material Material and man-hour, reduce cost;

2, few, the flexible operation of whole combination control piece is easy to use;

3, whole good rigidly uses safety.
