Description

The heterotype umbrella umbrella stand

The utility model relates to a kind of umbrella frame structure, and especially the umbrella bar occupies the heterotype umbrella of umbrella cover eccentric position or the umbrella stand of circular eccentric umbrella.

There is the people doing a lot of useful work aspect the research of heterotype umbrella, eccentric umbrella in recent years, makes the moulding of traditional circular parachute that variation arranged, and changed the position of umbrella bar, increased the effective protected area of umbrella.Weak point is: the support strength to heterotype umbrella with not isometric current bone or the longer current bone in the eccentric umbrella is not enough, and then influences propping up of corresponding site umbrella cover and tightening of whole umbrella cover, causes mobile difference of rainwater and profile attractive in appearance inadequately.And some umbrella frame structure is compared more complicated with original common umbrella, has increased certain difficulty to manufacturing.As the heterotype umbrella as described in the Chinese patent application 88210831.x, this umbrella does not have the skeleton that supports umbrella cover between stator and folded umbrella rib, thus the pulling force tensioning that this position umbrella cover can only lean on the folded umbrella rib to provide, and can not be propped up effectively.The described heterotype umbrella umbrella stand of Chinese patent application 88214584.3 for another example, though the main purpose of this utility model is to provide effective support for whole umbrella cover, but owing to each current bone on this umbrella stand, its length no matter, provide 2 supports by the last dish and the saddle of living, the dish and the span of living between the saddle are bigger on the longer current bone, the support strength that longer by contrast current bone is obtained is little, so it is not enough that the resulting support strength of this longer current bone is still disliked, and this utility model adopts is the saddle alive that can slide up and down along the current bone, to outer process whole umbrella cover is tightened so the current bone can not resemble the current bone of common umbrella, influenced practical effect and good looking appearance; The support opening-closing structure of this utility model than common umbrella complexity have increased the difficulty of making more in addition.

Prior art fails thoroughly to solve the umbrella cover support strength problem of heterotype umbrella or eccentric umbrella, trace it to its cause and be: no matter how its umbrella frame structure form changes, the current bone is still adopted 2 traditional supporting way, so no matter how the position of the strong point changes, the increase of the support strength that the current bone obtains is also not obvious, and longer current bone compares the also just obvious deficiency of the support strength that is obtained with other current bone photo.

For above-mentioned reasons, present various heterotype umbrellas or eccentric umbrella all do not have original common umbrella simple in structure, drive the intensity advantage of uniform away, generally do not accepted as yet by the public.

The purpose of this utility model be to provide a kind of be fit to various umbrella shapes, each current bone all can obtain basic identical support strength and the umbrella frame structure of folding smoothly still, simple in structure, the support strength that makes its various informative, pretective acreage advantage of reasonable that has both heterotype umbrella and original common umbrella evenly, folding advantage smoothly.

The purpose of this utility model is achieved in that the skeleton that utilizes original common circular concentric umbrella and does not change its supporting construction, just increased auxiliary support apparatus, this device is made of leverage, be installed on the umbrella stand, be used for providing the new strong point to the current bone that relative long needs increase its support strength.This auxiliary support apparatus drives frame away by several relatively independent propping up to be formed, and each bracing frame is supporting the end of a current bone.The quantity of bracing frame is determined that by concrete umbrella shape in same umbrella stand, according to the relative length of each current bone, each the current bone that long need is increased its support strength is provided with a bracing frame.

In above-mentioned umbrella stand, each relatively long needs increases the current bone of its support strength, except that two strong points that the supporting construction of original common umbrella stand provides, increased a new strong point again, the support strength that this selection of driving a position away obtains support strength that this longer current bone obtained and other current bone is basic identical.In the moving process of umbrella, the motion mode of auxiliary support apparatus is identical with the motion mode of original common umbrella supporting construction, so the smooth degree of this umbrella stand folding is identical with original common umbrella.The utility model has thoroughly solved umbrella cover for the various umbrella covers especially umbrella bar heart not placed in the middle effective support and the umbrella stand problem of folding smoothly still with this understanding is provided, and can reach the result of use of original common umbrella.

Making material of the present utility model, device therefor, specification requirement and technical process are identical with known umbrella, and the cost increase is very few, and general umbrella factory all can make, and easily generally accepts for the public.

Below in conjunction with accompanying drawing embodiment is elaborated.

Fig. 1 is the umbrella frame structure figure of the utility model embodiment, and to plot curved shape be to have considered the active force of umbrella cover to the current bone to the current bone among the figure.

Fig. 2 is the terminal Folding structure figure of longer current bone.

Fig. 3 is the movement position figure of umbrella stand.

In umbrella stand shown in Figure 1, last dish (6) is fixed on the top of umbrella bar (5), locating piece (7) is fixed on the appropriate location of umbrella bar, mid-game (4) and lower wall (2) are enclosed within on the umbrella bar and are slidingly matched with it, deployment spring (3) is enclosed within on the umbrella bar between mid-game and the lower wall, one end of longer current bone (14) and shorter current bone (1) is connected with hinge with last dish, one end and the mid-game of support bone (8) are hinged, the B point of the other end and longer current bone or the S of shorter current bone are point articulated, one end of steel wire pull bar (9) is hinged on the F point of lower wall, the B point of the other end and longer current bone or the S of shorter current bone are point articulated, auxiliary support bone (10), (11), (13) respectively there is an end to be connected on the hinge (12), the other end of auxiliary support bone (10) is hinged on the C point of dish, the other end of auxiliary support bone (11) is hinged on the E point of lower wall, and the other end of auxiliary support bone (13) is hinged on the A point of longer current bone.

Constituted the bracing frame of present embodiment by auxiliary support bone (10), (11), (13) of hinge (12) connection.

Each support bone (8) is isometric, its mode that supports the current bone is identical with original circular parachute, and its strong point has increased a strong point A in the auxiliary support bone (10) of the B point of the B of longer current bone (14) point and shorter current bone (1), (11), (13) for longer current bone (14).The selection of current bone length and some A is satisfied following condition: AB (arc length) ≈ BC (arc length)=RS (arc length), AQ (arc length)≤ST (arc length).By above-mentioned condition as can be known: the support strength that longer current bone (14) is obtained approximates or is not less than the support strength that shorter current bone (1) is obtained.

At the umbrella closure state, close up closely for making whole umbrella stand, should satisfy following condition: AB (arc length)+BC (arc length)=AD+DC, CD+DE=CB (arc length)+BF+FE.

The opening ways of present embodiment is a self-opening, and its mechanism no longer describes in detail with known Self-opened umbrella.

The closure of umbrella realizes along umbrella bar (5) decline by driving lower wall (2).In this process, lower wall (2) is by auxiliary bone (11) the pulling hinge (12) that drives away, it is the D point, reach by the B point on the longer current bone of steel wire pull bar (9) pulling and draw close to the umbrella bar, distance between B point and the D point is dwindled gradually, because the current bone is made by elastic wire, longer current bone (14) will stretch gradually with auxiliary support bone (10), (13) and fit together, and last whole umbrella stand closely closes up together.Umbrella stand movement position figure sees Fig. 3.

For making each the current bone under the closure state have equal length, the end of longer current bone can be made convertible, see Fig. 2, its preparation method no longer describes in detail with existing system umbrella technology.
