CN2130048Y - Umbrella without spring - Google Patents

Abstract

The utility model relates to an improvement on an all-weather umbrella which comprises an umbrella handle, an umbrella rod, an umbrella frame, an umbrella surface and an upper and a lower disks. The utility model is characterized in that a supporting frame and a pulling strip are hinged on the upper and the lower a lower position between a long frame and the lower disk; the non-extendible pulling strip at the lower side can keep the flexible supporting frame at an elastic state in the process of opening the umbrella surface; while the lower disk is pushed upwards along an umbrella rod, the supporting frame humps increasingly and then decreasingly; when the lower disk (9) moves to a climax, and the umbrella surface is opened completely, the supporting frame is still at an elastic humping state or in a right straightening state. The utility model optimizes the structure of the umbrella, omits traditional positioning structure of a flat spring or an umbrella opening spring, and simplifies manufacturing process.

Description

Umbrella without spring

The utility model is a kind of improvement invention about en-toutcas.

It struts existing known en-toutcas detent mechanism and all adopts Compression and Expansion deployment spring or flat spring structure, be enclosed within when moving on the lower wall on the umbrella bar and strut umbrella cover by umbrella frame, at this moment, the elastic force of deployment spring or the positioning action of flat spring are fixed on umbrella cover and strut the position, the en-toutcas of said structure is owing to need to offer a groove on the umbrella bar, deployment spring and flat spring easily get rusty or are fragile and influenced life-span of en-toutcas in addition, make rather cumbersome simultaneously.

The purpose of the utility model is intended to overcome the existing in prior technology deficiency and a kind of new no spring en-toutcas that struts automatic positioning mechanism that has is provided, and can optimize the en-toutcas structure.

This no spring en-toutcas still includes umbrella handle, umbrella bar, umbrella frame, umbrella cover and goes up dish, lower wall, it is characterized in that hinged support bone and the tie rod of being provided with in upper and lower position between long bone and lower wall, and the underlaid tie rod that do not extend makes flexible support bone strut at umbrella cover all to be in the elasticity state that arches in the process, when on the umbrella bar, pushing away with lower wall, support bone arches to increase thereupon and then reduces, when lower wall rose to the peak umbrella cover and struts fully, support bone was in still that elasticity is arched or straight configuration just.Because support bone is along with lower wall rises through an elastic force balance deformation process, must overcome the support bone elasticity deformation force that arches when the lower wall that rises to peak is descended again again increases and can achieve one's goal, therefore, said structure makes umbrella cover strut automatic location easily, has realized the utility model purpose.

It is when umbrella cover struts fully that the utility model further is provided with, Shen Suo tie rod is not in umbrella bar cramp angle and still is less than 90 °, and this moment is no matter support bone is between lower wall and long bone and stretches or reverse elasticity still can strut umbrella cover when arching and en-toutcas is closed up.

The utility model has abandoned deployment spring fully and flat spring struts location structure, has optimized the en-toutcas structure, reduces and simplified manufacture difficulty and operation simultaneously.

Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously:

Fig. 1 is the utility model example structure view.

Fig. 2 is the local two kinds of status architecture enlarged drawings of Fig. 1.

Wherein: 1: umbrella top, 2: go up dish, 3: gag lever post, 4: on press from both sides horse, 5: folder horse down, 6: tie rod, 7: support bone, 8: long bone, 9: go up dish, 10: umbrella bar, 11: umbrella handle, 12: pearl head, 13: umbrella cover, 14: waistband.

As shown in Figure 1, the key that realizes the utility model purpose is the automatic positioning mechanism be made up of tie rod (6) and support bone (7), under the prerequisite that keeps tie rod (6) not extend, when lower wall (9) rises, flexible support bone (7) is in the elasticity state that arches always, when lower wall (9) slides at umbrella bar (10) middle part, the elasticity of flexible support bone (7) the deformation force maximum of arching, when lower wall (9) up promotes again, the elasticity of flexible support bone (7) deformation force that arches descends thereupon, lower wall this moment (9) is almost had a few automatically or past easily the rising until offseting with gag lever post (3), umbrella cover (13) also struts fully and locatees automatically, be in that support bone (7) between lower wall (9) and the long bone (8) is that elasticity is arched or just straight configuration all can, setting tie rod (6) does not promptly extend and does not shorten, and still be less than 90 ° with umbrella bar (10) angle, state like this, then locating effect is better, as shown in Figure 2, the support bone (7) and tie rod (6) hinged with long bone (8), their folder horse (4,5) can design with long bone (8) one, also can be fixed on the long bone (8) by cartridge clip, in order to make long bone (8) compatible better when umbrella closes up with support bone (7) and tie rod (6), might as well will go up folder horse (4) and set a little higher than folder horse (5) down or only be set as bent sub (7 ') shape in support bone (7) and last folder horse (4) hinge segment, this bent sub (7 ') can be fixed as one with design of support bone (7) one or suit.Umbrella cover (13) is when closing up, because the effect of power is stretched in flexible a kind of recovery of support bone (7) elastic bow time-out, lower wall (9) is moved down along umbrella bar (10) automatically, the tightly obvolvent mutually under above-mentioned restoring force effect of corresponding long bone (8) and umbrella cover (13) has overcome the loose diffusing phenomenon of pine when en-toutcas was not waistband (14) after gathering in the past.

Claims (2)

1, a kind of no spring en-toutcas, include umbrella handle, the umbrella bar, umbrella frame, on umbrella cover reaches, lower wall, on it is characterized in that between long bone (8) and the lower wall (9), hinged flexible support bone (7) and the tie rod (6) of being provided with of upper/lower positions, the underlaid tie rod (6) that do not extend makes flexible support bone (7) all be in the elasticity state that arches in the process strutting of umbrella cover (13), when on umbrella bar (10), pushing away along with lower wall (9), support bone (7) arches to increase thereupon and then reduces, when lower wall (9) rises to peak umbrella cover (13) when strutting fully, short bone (7) is in still that elasticity is arched or straight configuration just.

2, according to the described no spring en-toutcas of claim 1, it is characterized in that umbrella cover (13) when strutting fully, Shen Suo tie rod (6) still is not less than 90 ° with umbrella bar (10) angle.
