Abstract

The utility model discloses a wind-proof umbrella frame which is mainly composed of a main umbrella frame, and a prearranged number of outer top frame, inner top frames, tension frames and linkage frames, wherein, an auxiliary top frame is pivoted between the pivot parts of the inner top frames and the outer end edges of the outer top frames; the outer end of the auxiliary top frame makes use of a spacer body in a T shape to be pivoted with the outer top frames; the coordination of the auxiliary top frame increases firmness of an umbrella frame, which prevents the umbrella form being damaged by strong wind force.

Description

Wind-proof umbrella frame

The utility model relates to a kind of Wind-proof umbrella frame, belongs to the parachute kit field.

Progress, development of science and technology along with the epoch, the go out utensil that is used to protect from the wind and rain of people is more and more easier, practical, wherein, parachute kit is a wherein example, and the use of parachute kit not only just is used to take shelter from rain concerning the modern, situation such as its effect also can be used in sunshade, keep out the wind, but, general parachute kit is used to keep out the wind or when hiding rain, as runs into the situation that bigger wind-force often causes what is called " parachute-opening flower " easily, not only causes harmful effect and user to have no a sense of safety easily to parachute kit.Please referring to shown in Figure 1, the parachute kit of generally commonly using mainly is by main umbrella skeleton 1, outer parietal bone 2, interior parietal bone 3 and interlock bone 4, tension force bone 5 is formed, wherein, outer parietal bone 2 is all bent member with interior parietal bone 3, the edge appropriate location is formed with pivot part 21 in the stage casing, 31, an end of parietal bone 3 is hubbed on the pivot part 21 of outer parietal bone 2 in being somebody's turn to do, end then is hubbed on the periphery appropriate location of main umbrella skeleton 1 simultaneously with outer parietal bone 2 in addition, simultaneously, these interlock bone 4 two ends are hubbed on the articulated section of pivot part 31 and the outer parietal bone 2 and the main umbrella skeleton 1 of interior parietal bone 3 respectively, this tension force bone 5 then is hubbed on the pivot part 21 of outer parietal bone 2 and the appropriate location of interlock bone 4 respectively, structure whereby, make parachute kit can make things convenient for folding and possess the effect that protects from the wind and rain, the outer parietal bone 2 of general parachute kit all is slightly to be inclination＜font, makes the rainwater drippage of can taking advantage of a situation, but but so the wind at this place that flows through can't be discharged, when the wind-force that converges surpasses tension force bone 5 negative severe, promptly cause the situation (as shown in Figure 2) of what is called " parachute-opening is colored ".

The purpose of this utility model provides a kind of simple in structure, umbrella frame of possessing windproof effect when using, not only can increase the steadiness of umbrella rib structure, more can effectively avoid the situation of " parachute-opening flower " to take place.

For achieving the above object, solution of the present utility model is: a kind of Wind-proof umbrella frame, mainly be by a main umbrella skeleton and one group of outer parietal bone, interior parietal bone, tension force bone and interlock bone are formed, interior parietal bone one end is to articulate with the pivot part of outer parietal bone, end then simultaneously is hubbed on the main umbrella skeleton respectively with outer parietal bone in addition, the articulated section of the pivot part of parietal bone and outer parietal bone and main umbrella skeleton in interlock bone two ends are hubbed on respectively, wherein between the external end edge of the pivot part of this interior parietal bone and outer parietal bone, other is pivoted with a secondary parietal bone, and this pair parietal bone outer end utilizes an interval body that slightly is the T font to articulate with outer parietal bone.

Above-mentioned Wind-proof umbrella frame, wherein secondary parietal bone are articulated by interior fulcra and outer fulcra, and its articulated section is provided with the binding sheet, and other of this bindings sheet holds and then be hubbed on the pivot part place of outer parietal bone, and are provided with two chutes that are beneficial to the articulated part slip on brace.

After adopting such scheme, because the setting of secondary parietal bone, and strengthened whole umbrella rib structure, and the situation of avoiding umbrella frame to bloom; Link the setting of sheet simultaneously, and be provided with and be beneficial to the chute that articulated part slides, when parachute kit runs into high wind, can make umbrella frame have more elasticity and be difficult for the parachute-opening flower.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 7 is a partial sectional view of the present utility model.

See also Fig. 3～shown in Figure 6, the utility model Wind-proof umbrella frame mainly is made up of with tension force bone 5 outer parietal bone 2, interior parietal bone 3, the interlock bone 4 of a main umbrella skeleton 1 and predetermined number, commonly uses the structure of product together in view of above-mentioned member, do not add at this and to give unnecessary details, and of the present utility model being characterised in that:

Between the pivot part 31 of this interior parietal bone 3 and the external end edge of outer parietal bone 2, other is pivoted with a secondary parietal bone 6, this pair parietal bone 6 is articulated by interior fulcra 61 and outer fulcra 62, its junction is provided with two and links sheet 63, the end in addition that links sheet 63 is hubbed on pivot part 21 places of outer parietal bone 2, link sheet 63 and be provided with two chutes 631, the articulated part 211 of pivot part 21 slides over respectively in two chutes 631 with the articulated part 212 of interior fulcra 61 with outer fulcra 62, when bearing wind-force in the umbrella cover, articulated part 211,212 can slide up and down in two chutes 631 that link sheet 63, to increase the elasticity of umbrella rib structure, outer fulcra 62 outer ends of this pair parietal bone 6 utilize an interval body 64 that slightly is the T font to articulate with outer parietal bone 2, separate a suitable width between the two, simultaneously, interval body 64 both sides are convexly equipped with two fulcrums 641, so that the second umbrella layer 7 to be set, and make the outer parietal bone 2 and the width at secondary parietal bone 6 intervals form a diversion space A, with the wind direction of directed stream through this place, simultaneously, increase the steadiness of umbrella rib structure.

Feature by above-mentioned member, can utilize the setting of secondary parietal bone 6, make the first umbrella layer, 8 back of the body edge form one second umbrella layer 7 in addition and be provided with several potholes 9, to form a diversion space A between the two, make parachute kit possess the characteristics of water conservancy diversion wind direction, and the situation of avoiding umbrella frame to bloom, please referring to shown in Figure 6, the formed diversion space A of the utility model is by the interior gradually-reducing shape that is outward, be that its sectional area changes be by greatly and little structure, therefore by chance meet the venturi tube principle, when bearing bigger wind speed in the umbrella, the bootable wind direction of diversion space A is discharged outside the umbrella rapidly, and the situation that can not cause parachute-opening to spend, simultaneously, the form of 2 of the pivot part 31 of parietal bone 3 and outer parietal bones makes the structure of umbrella frame integral body more firm in being arranged on by this pair parietal bone 6.
