Abstract
The utility model relates to an umbrella rib structure of a folding umbrella; the umbrella comprises a central rod and a plurality of umbrella rib groups; the umbrella rib groups comprises a first section-rib, a second section-rib and a third section-rib, a support rib, a connection rob and a second connection rob, wherein, the pivot part of the second section-rib and the third section-rib is provided with a guide slot comprising a slow-speed slot and a clamping slot; the connection rod for connecting the first section-rib and the third section-rib is penetrated in the hollow body of the second section-rib. When the umbrella is opened to an approximately opening state, users can open the umbrella without taking too much labor.
Description
The utility model is a kind of umbrella rib structure of rolling over umbrella, refer to especially a kind of when umbrella struts its each umbrella frame can launch fully automatically with folding, and need not take the umbrella rib structure of the folding umbrella that too big strength can launch.
Consult shown in Figure 1, the umbrella frame structure of early stage folding umbrella comprises rod 1 and plural groups umbrella frame group 2 (only showing wherein a group among the figure) in one, those umbrella frame groups are as the skeleton of umbrella cover, the umbrella frame group 2 of its each group comprises a first segment bone 21, one second joint bone 22, one the 3rd joint bone 23, one fulcra 24 and a connecting rod 25, first segment bone 21, the second joint bone 22 and the 3rd joint bone 23 utilize the pivot joint mode to reach folding purpose, wherein the first segment bone 21, the second joint bone 22, connecting rod 25 and fulcra 24 are with pivoting point A, B, C, D, be connected with and reach continuous action relation, so when this umbrella struts or packs up, but this first segment bone 21 and second saves strutting of bone 22 interlocks or folding, the 3rd then extra processing of palpus of joint bone 23, can be with this umbrella normal or pack up with manual controlling party, this be one of its shortcoming; Other has a kind of umbrella rib structure of rolling over umbrella, see also shown in Figure 2, this pack contains rod 3 and plural groups umbrella frame group 4 (only showing wherein a group among the figure) in one, the umbrella frame group 4 of its each group comprises a first segment bone 41, one second joint bone 42, one the 3rd joint bone 43, one fulcra 44, one connecting rod 45 and second connecting rod 46, can find by Fig. 1 and Fig. 2 comparison, the folding umbrella of Fig. 2 is established a connecting rod than the folding umbrella of Fig. 1 more, and this connecting rod 46, first segment bone 41, the second joint bone 42, the 3rd joint bone 44 is with pivoting point E, F, G, H, be connected with and reach continuous action relation, so this umbrella struts or when closing one's umbrella, the joint bone of its each umbrella frame all can launch normally automatically or be folding, thereby solves early stage shortcoming as Fig. 1 umbrella frame.
See also shown in Figure 3ly, show that the folding umbrella of Fig. 2 struts to moving complete open state, when this umbrella struts fully, its down honeycomb 47 root edges and last catapult 48 upper limbs shelves are only mutually.In this umbrella design tactics, for avoiding producing folding problem when the 3rd joint bone 43 opens an umbrella, this folding umbrella is in strutting to being close to when opening fully, its the 3rd joint bone 43 and the second joint bone 42 have been in the state that is in line approximately, when continuing to strut when finish, produce the active force that tool strains at the connecting rod 46 and the second joint bone 42, then this connecting rod 45 also forms relative drag with the second joint bone 42, this drag is formed because of distortion by the second joint bone 42 and connecting rod 46, the deformation extent of the connecting rod 46 that right tradition is general and the second joint bone 42 is little, for the user, then must spend the drag that suitable strength overcomes each umbrella frame group could strut this umbrella, and this is one of its shortcoming; Strained at when the effect and work as connecting rod 46,46 on connecting rod saves bone 43 to the 3rd and also produces the effect that strains at, thereby makes the 3rd joint 43 be difficult for fold back effect takes place in opening an umbrella, and the umbrella cover that struts like this also can reach well-balanced property.The umbrella of this structure, Gu umbrella more shown in Figure 1 has suitable improvement, but it still need spend suitable strength, the beginning can strut umbrella, the part of still having regret unavoidably.
The utility model one purpose provides a kind of umbrella rib structure of rolling over umbrella, must make the interlock expansion fully automatically of this umbrella frame with folding.
Its two purpose of the utility model provides a kind of folding umbrella, and making its user needn't spend too big strength can strut umbrella cover.
Its three purpose of the utility model is when folding umbrella the 3rd joint bone and the straight approximately softened state of the second joint bone, and a buffering is provided, and in the time of must making this umbrella continue to strut umbrella cover, the user can strut umbrella cover in the face of less drag.
The technical solution of the utility model is: rod and plural groups umbrella frame group during this pack contains, those umbrella frame groups comprise a first segment bone, one second joint bone, one the 3rd joint bone, fulcra, a connecting rod and a second connecting rod.
The articulated section that this second joint bone and the 3rd joint articulate is provided with guide groove 71, and this guide groove 71 comprises jogging groove 72 and slot 73; And
This second joint bone sets firmly a node 8 and nearly articulated section end, wherein this node 8 is a ducted body, be connected with in the connecting rod of first segment bone and the 3rd joint bone and be arranged in wherein, by this, the drive-connecting shaft of the second joint bone is the axle center with the slot of the 3rd joint bone articulated section, this two joints bone is launched, make up this two joints bone and be expanded to and be in line approximately and when continuing to launch, this drive-connecting shaft imports jogging groove.
