The specific embodiment
The multi-fold umbrella that multi-fold umbrella umbrella frame of the present utility model can be applicable to automatically or hand is opened, below take triple folding umbrella and is described in further detail by reference to the accompanying drawings as example.
As shown in Figure 2, multi-fold umbrella umbrella frame of the present utility model comprises: the first umbrella frame 1, the second umbrella frame 2 and the 3rd umbrella frame 3 that connect successively from the inside to the outside, outer end is connected in the 4th umbrella frame 7, bracing wire 4 and the bracing wire 8 at described the first umbrella frame 1 middle part.Described the 3rd umbrella frame the inner is fixedly installed the first joint 31, the second inside and outside two ends of umbrella frame 2 are installed with respectively the 4th joint 25 and the second joint 21, the first umbrella frame 1 outer end is installed with the 3rd joint 11, the 4th umbrella frame 7 outer ends are installed with the 5th joint 71, and above-mentioned each joint adopts plastic material to make conventionally.Described bracing wire 4 two ends connect respectively the 3rd joint 11 of the first umbrella frame 1 outer end and first joint 31 of the 3rd umbrella frame 3 the inners, and bracing wire 8 two ends connect respectively the 5th joint 71 of the 4th umbrella frame 7 outer ends and the 4th joint 25 of second umbrella frame 2 the inners.Described the second umbrella frame 2 is provided with the lug boss 5 with through hole 51, and described bracing wire 4 is passed and can be prevented bracing wire 4 displacements from the through hole 51 of this lug boss 5.
As shown in Fig. 3, Fig. 4 and Fig. 5, described lug boss 5 comprises a base portion 52 and from upwardly extending the first extension 53 of this base portion 52, the second extension 54 and the connecting portion 55 that connects this first extension 53 and the second extension 54.Described the first extension 53, the second extension 54 and connecting portion 55 form makes somebody a mere figurehead the corridor bridge-like structure on base portion 52, and the built on stilts portion between this corridor bridge-like structure and base portion 52 forms the described through hole 51 that can pass for bracing wire 4.Described base portion 52, the first extension 53, the second extension 54 and connecting portion 55 structure that is formed in one, and stagger and are arranged at respectively the left and right sides of described base portion 52 in described the first extension 53 and the second extension 54 front and back, this structure greatly facilitates the injection mo(u)lding of lug boss 5, need not when injection mo(u)lding, also need extra contact pin step could form through hole like that by existing lug boss 5 as shown in Figure 1.In the present embodiment, described base portion 52 is shaped in described the second umbrella frame 2 middle parts.
In order to prevent that the clasp joint end hook of bracing wire hinders umbrella cloth, multi-fold umbrella umbrella frame of the present utility model has also been done improvement to the structure of bracing wire and rib joint clasp joint end.
As shown in Figure 6 and Figure 8, described bracing wire 4 outer ends and the first joint 31 clasp joint places bend L-shaped clasp joint portion 41, and these clasp joint portion 41 ends are provided with the large fastener 42 of these bracing wire 4 diameters of width.On described the first joint 31, offer a shoulder hole 32, the aperture of this shoulder hole 32 is one large one small, described in its aperture ratio of larger one end, the width of fastener 42 is large, and its aperture of the less other end is a bit larger tham the diameter of described bracing wire 4 but is less than the width of fastener 42.During assembling, utilize the elasticity of plastic connector itself that the clasp joint portion 41 of described bracing wire 4 ends is clamp-oned until described fastener 42 enters shoulder hole 32 aperture larger parts from shoulder hole 32 compare little one end, aperture, now, this fastener 42 will be stuck in this aperture larger part and be difficult for deviating from, the outer face of clasp joint portion 41 falls in shoulder hole 32 completely does not expose, thereby can effectively prevent that clasp joint portion 41 end hook hinder umbrella cloth.In the present embodiment, described fastener 42 flattens bracing wire 4 ends and form.
The structure of above-mentioned bracing wire 4 outer end clasp joint portions 41 and the first joint 31 shoulder holes 32 can be applied to the clasp joint place of bracing wire 8 outer ends and the 4th joint 25 equally, repeats no more herein.
In order to simplify manufacture craft, in the present embodiment, between described the second joint 21 and described the first joint 31, by the first bent flexible connecting member 61, be connected, described the first joint 31, the second joint 21 and the first flexible connecting member 61 adopt plastic materials one-body molded.Similarly, between described the 3rd joint 11 and the 4th joint 25, by the second bent flexible connecting member 62, be connected, described the 3rd joint 11, the 4th joint 25 and the second flexible connecting member 62 adopt plastic materials one-body molded.But after employing said structure, under deployed condition, when umbrella cover is subject to wind-force effect and while turning up, is easy to occur the situation that lateral deviation is moved relatively partially between two joints that are connected, cause umbrella rib structure unstable, also easily cause the damage of joint.For this reason, multi-fold umbrella umbrella frame of the present utility model has also been made improvement to the structure of two joint junctions.
As shown in Figure 6 and Figure 7, the side that described the first joint 31 contacts with described the second joint 21 under deployed condition convexes with the first raised line 33 of a strip, described the second joint 21 is provided with the baffle plate that stops these the first raised line 33 skews in the left and right sides with these the first raised line 33 corresponding positions, position, this baffle plate comprises the first baffle plate 22 and the second baffle 23 that is arranged at respectively described second joint 21 left and right sides, and staggers before and after the position of this first baffle plate 22 and second baffle 23.During parachute-opening, as shown in Figure 7, the first raised line 33 of strip is folded between the first baffle plate 22 and second baffle 23, can prevent the inclined to one side side displacement between the first joint 31 and the second joint 21, and the structure staggering in the first baffle plate 22 and second baffle 23 front and back has facilitated this second joint 21 once injection mouldings and die sinking, without extra step.In addition,, in order to reduce size of folded umbrella, described the second joint 21 is provided with for holding the lower recess 24 of this first raised line 33 with the first raised line 33 corresponding positions, position under deployed condition.
Above-mentionedly prevent that the structure being shifted between joint can be applicable to the 3rd joint 11 and the 4th joint 25 equally, as shown in Figure 2, the side that described the 4th joint 25 contacts with described the 3rd joint 11 under deployed condition convexes with the second raised line 26 of a strip, described the 3rd joint 11 is being provided with for holding the lower recess 15 of this second raised line 26 with these the second raised line 26 corresponding positions, position, stagger before and after being respectively equipped with and stopping these the second raised line 26 the 3rd baffle plates 12 of skew and the position of the 4th baffle plate 13, the three baffle plates 12 and the 4th baffle plate 13 in these lower recess 15 left and right sides.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
