Description

Umbrellas without frames for use in clear and rain days

The utility model relates to a kind of chassis less construction, and cover-up surface is big, and the folded en-toutcas of collapsible volume.

Existing en-toutcas mainly is made up of other part such as long bone, short bone and straight-bar, handle, umbrella cover, tie-point is many between the long bone of formation shell system, short bone, complex structure, fragile, more with material, and straight-bar and short bone occupied the center of umbrella, and effective cover-up surface is reduced, the straight-bar end on the long bone end on umbrella edge and umbrella top is very sharp-pointed, uses and feels unwell entirely.

The purpose of this utility model is the deficiency that exists at existing skeleton en-toutcas, provides a kind of structure diverse, lightly economizes material, and effectively cover-up surface is big, safe in utilization, and telescopic scrolling is folded, portable exoskeletal en-toutcas.

Solution of the present utility model is: adopt the strut of three or four poles as umbrella, an end of pole is drilled with the hole, so that hinged with umbrella handle, umbrella cover is made with round wire ring and waterproof soft material, by the pole number buttonhole and little pad is set on the umbrella cover.

The pole that another is characterised in that the composition strut of the present utility model is made with telescopic sleeve pole.

The using method of this umbrella is: umbrella cover is launched, promptly form a straight umbrella cover of being tightened by the steel wire ring, the cap sleeve of buckleing that will form each pole one end of strut is then gone in the buttonhole on the umbrella cover, promptly becomes an exoskeletal en-toutcas.The method for folding of this umbrella is: pole is buckled cap takes off, shrink and to close up each pole from umbrella cover, the folded umbrella cover wire loop of volume, will shrink then and roll up pole, the umbrella cover folded pack into the oblateness that can doublely make satchel collect wrap in.

Exoskeletal en-toutcas of the present utility model is simple in structure, easy to manufacture, economize the material material-saving, production cost is low, not only economize metal material, and economize the umbrella cover materials, and in light weight, be easy to carry, effectively cover-up surface is big, common umbrella straight-bar and short bone frame have occupied the center of umbrella, and this umbrella user can place head the center of umbrella, and effective shielded area is increased.Moreover the umbrella of this umbrella does not have sharp-pointed skeleton and protrudes along being the wire loop ring, therefore, does not have the danger of hurting sb.'s feelings during use.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is exoskeletal en-toutcas unfolding state figure;

Fig. 2 is the schematic diagram after exoskeletal en-toutcas strut shown in Figure 1 draws in;

Fig. 3 is the schematic diagram of exoskeletal en-toutcas umbrella cover volume poststack shown in Figure 1;

Fig. 4 is the handbag schematic diagram that is used for the folding back collection of exoskeletal en-toutcas.

Embodiment: this en-toutcas of (see figure 1) comprises strut system that is made up of three poles 8 and the umbrella cover 5 that has been stretched tight by wire loop, and umbrella handle 4 is formed, pole 8 adopts telescopic sleeve pole to make, the sleeve pole is made by metal tube, but appearance chromium plating or zinc-plated or nickel plating etc., female bar 1 diameter of sleeve 5～7mm, wall thickness 0.1～0.5mm, the bottom is flat and is drilled with aperture, so that connect with umbrella handle 4, king-rod 2 and sub bar 3 diameters reduce successively, with the female bar 1 of king-rod 2 retractions, sub bar 3 retraction king-rods 2 are not loosening is advisable, all there is spring leaf the bottom of king-rod 2 and sub bar 3, after being pulled out, it can not withdraw easily, sub bar 3 tops have button cap 7(to see Fig. 2), so that connect with umbrella cover 5; umbrella handle 4 is made by metal or nonmetallic materials; an end of umbrella handle 4 has the groove that is used to connect female bar 1; so that three poles 8 are hinged to one with umbrella handle 4; and can actuate freely; umbrella cover 5 is made by the waterproof soft material, and diameter is 0.6～0.9m, and umbrella is along being surrounded by the wide preferably 3～5mm of elasticity; the round wire ring 9 of the flat wire of thick 0.3～1mm or diameter 1.5～2.5mm is tightened umbrella cover 5; have on the umbrella cover 5 by etc. the little pad 6 of 3 bracelet eyes of angular distribution so that join and increase the intensity of connection place umbrella cover 5 with button cap 7 on the sub bar 3, the length of side that waits triangle is 35～45cm; so that the user can be in umbrella cover 5 and hit exactly, and effectively utilizes umbrella cover 5.
