Description

Automatic umbrella combined type fulcra

The utility model relates to a kind of fulcra of automatic umbrella.

The automatic umbrella of tradition as shown in Figure 1, on middle mandrel rod 10, fix nest 11 on, and nest 12 in the slip cap unification, nest 13 once, and installing one compression spring 14 between middle nest 12 and the following nest 13, upper, middle and lower nest 11,12,13 peripheries then are pivoted respectively can open outward umbrella frame 15, fulcra 16 and tie rod 17, make fulcra 16 outer ends articulate umbrella frame 15, the middle section then articulates tie rod 17, constitutes automatic umbrella.

Commonly use automatic umbrella and adopt flute profile metal fulcra 16, not only weight is heavier, get rusty easily, and metal fulcra 16 must punching out before, during and after the pivot hole, wherein the place is the easiest in pivot hole 18 in the middle of especially ruptures, bulk strength is not ideal enough.

No. 242225 " the binding structure of umbrella stand " case of the Taiwan patent announcement that the design people's application is got permission, as shown in Figure 2, be to fix a hardware 21,22 in end and each crimping of pars intermedia of glass fibre or carbon fiber umbrella frame 20, make plastic overmold hardware 21,22 with integrated method again, to form coupling member 23,24 shown in Figure 3.

Above-mentioned glass fibre or carbon fiber umbrella frame 20 have good elastic force and intensity, but can't be directly one-body molded go out coupling member, can only first crimping hardware 21,22, and then ejaculation coating plastic coupling member 23,24.Especially when this technology was diverted to the fulcra of automatic umbrella, because fulcra must mold three coupling members such as both ends and pars intermedia, and a bone length had only umbrella frame 1/2nd following length, cause speed of production slow, increase cost, and location difficulty, do not meet economic benefit.

If fulcra have been adopted the synthetic resin material, though can be directly one-body molded go out two ends and pars intermedia coupling member, the elastic force and the intensity of synthetic resin fulcra do not reach standard, do not conform to ideal.

The purpose of this utility model is to provide a kind of automatic umbrella combined type fulcra, can increase substantially speed of production, save cost, and make fulcra reach ideal tensile strength, durable in use, Never-rusty thoroughly solves drawbacks such as the structure of commonly using metal, plastics or glass fibre fulcra and use.

The technical solution of the utility model is:

A kind of automatic umbrella combined type fulcra, formed by a short plastic sleeving connecting rod and fulcra, a this plastic sheath extension bar wherein end has axial centre bore, the opposite end of these fulcra is inserted this centre bore and is combined with this plastic sheath extension bar, and the plastic sheath extension bar is at the lug that has the pivot hole near the bottom surface of this end one-body molded, and the other end of plastic sheath extension bar then one-body molded has the pivot joint ear in pivot hole.

Described automatic umbrella combined type fulcra is characterized in that: the lug of this plastic sheath extension bar bottom surface is established a pivot hole of running through lug.

Described automatic umbrella combined type fulcra, it is characterized in that: the lug of this plastic sheath extension bar bottom surface is made as two symmetries of being separated by, and is provided with the pivot hole that communicates.

Described automatic umbrella combined type fulcra, it is characterized in that: these fulcra are carbon fiber fulcra.

Described automatic umbrella combined type fulcra, it is characterized in that: these fulcra are glass fibre fulcra.

Effect of the present utility model is:

Comprehensive the above, automatic umbrella combined type fulcra of the present utility model, adopt short plastic sleeving connecting rod to combine with a glass fibre or the inserting of carbon fiber fulcra, can increase substantially speed of production, save manpower, man-hour, take into account the elasticity and the intensity of fulcra, durable in use, Never-rusty thoroughly solves drawbacks such as the structure of commonly using metal, plastics or glass fibre fulcra and use.

At first, see also Fig. 4,5, automatic umbrella combined type fulcra of the present utility model, formed with a glass fibre or carbon fiber fulcra 60 by a short plastic sleeving connecting rod 50, this plastic sheath extension bar 50 a wherein end combines with the opposite end grafting of fulcra 60, and plastic sheath extension bar 50 is at the lug 52 that has pivot hole 54 near the bottom surface of this end one-body molded, supply crotch 41 clasp joints of nest tie rod 40 down, the other end of plastic sheath extension bar 50 then one-body molded one has the pivot joint ear 53 in pivot hole 55, with nest in articulating.

See also Fig. 5,6, this weak point plastic sleeving connecting rod 50 a wherein end has axial centre bore 51, inserts centre bore 51 for the opposite end of glass fibre or carbon fiber fulcra 60 and forms tight fit, even can add sticker between the two; Certainly also can consider plastic sheath extension bar 50 at the inserting section direct injection coating plastic of fulcra 60.The lug 52 default one of these plastic sheath extension bar 50 bottom surfaces runs through the pivot hole 54 of lug 52, to cooperate crotch 41 clasp joints of tie rod 40.

Plastic sheath extension bar 50 one ejection formation lugs 52, pivot joint ear 53 and pivot hole 54,55, can significantly improve speed of production, save cost, and plastic sheath extension bar 50 adopts short type design, can reach ideal tensile strength, further cooperate glass fibre or carbon fiber fulcra 60, constitute desirable combined type fulcra with better intensity.In the embodiment shown in fig. 7, the pivot joint ear 53 of short plastic sleeving connecting rod 50 articulates the middle nest 32 of mandrel rod 30 in the automatic umbrella, the crotch 41 of the tie rod 40 of nest 33 under 52 clasp joints of the lug of bottom surface, opposite end, and the coupling member 61 of glass fibre or carbon fiber fulcra 60 ends is to articulate umbrella frame 34 stage casings of going up nest 31, constitutes the combined type fulcra.

See also Fig. 8, the lug 520 of these embodiment plastic sheath extension bar 500 bottom surfaces is set as two symmetries of being separated by, and the default pivot hole 540 that communicates, and inserts for the pivot joint ear 410 of tie rod 400, adopts rivet 412 to articulate pivot hole 540,411 again.
