Abstract

The utility model discloses an eccentric umbrella, which having the advantages of reasonable structure and simple manufacture is an improved eccentric umbrella which can realize the four working conditions of eccentricity, twist, inclination and upright action. The performance of the utility model is realized by an opening ball seat arranged between the lower part and the middle part of an umbrella rod, a ball head and other devices. The eccentric umbrella is an ideal multidirectional appliance used for shielding rain and sunlight.

Description

Improved eccentric umbrella

A kind of rainproof sunproof apparatus, particularly a kind of improvement eccentric umbrella of relating to.

The kind of eccentric umbrella is more, comprise that application number is the three folding eccentric umbrellas of 91224822X, at most also can only be when using bulb to connect three sections umbrella bars with ball cup, and adopt the form of this Figure of description Fig. 4 just can make a parachute kit off-centre be arranged, reverse, tilt and uprightly use this four kinds of main performances.

The purpose of this utility model provides a kind of existing eccentric umbrella that is different from, its structure rationally, makes easy, no matter easy to use and adopt the sort of form can both realize off-centre, reverse, tilt and the upright improvement eccentric umbrella of four kinds of groundwork states of use.

Task of the present utility model is to be achieved on the basis of improving existing eccentric umbrella, its implementation is that the umbrella bar that will become three sections is connected by one pair of bulb and opening ball cup and a hinge, and the opening ball cup must or be riveted with the lower umbrella rod welding, the bulb part must be connected with middle umbrella bar, and hinge connects with middle umbrella bar and upper umbrella rod.Lower umbrella rod is equipped with the strut that the two fork of band ear colludes, in umbrella bar (or three sections umbrella bars are equipped with twister between lower umbrella rod and middle umbrella bar when being connected by two hinges) (or umbrella bar length is flexible and fixing in also can making) compound sliding sleeve (or low sleeve and middle sliding sleeve) is housed, the upper sliding sleeve that is equipped with on compound sliding sleeve and the upper umbrella rod is connected by connecting rod (or connecting rod adopt flexible and can be fixed connecting rod), and compound sliding sleeve can be connected with strut or disconnect.Owing to adopt one pair of bulb and opening ball cup (or twister) and a hinge (or two hinges) to connect the form of three sections umbrella bars and compound sliding sleeve (or big sliding sleeve and middle sliding sleeve), duty when umbrella cover is strutted, after being converted into angle, the middle relatively umbrella bar of upper umbrella rod still can reverse around middle umbrella bar axis, again owing to respectively slide over and be fixed on the umbrella bar and can not slide, and strut be connected with compound sliding sleeve (or low sleeve) can keep selected off-centre like this reverse or tilt or upright duty constant.

Adopted twister to connect down in several (being not whole) of the present utility model form, the method of middle umbrella bar, again owing to adopted compound sliding sleeve (or low sleeve and middle sliding sleeve), and without clip, no matter adopt use that the sort of form can both make the umbrella bar by eccentric or reverse or tilt or upright four kinds of main state variation, and it is constant to be fixed.So just discloseder eccentric umbrella is flexible, firm.

Provide embodiment of the present utility model below by accompanying drawing:

1 long umbrella rib among the figure, 2 short umbrella frames, 3 umbrella crowns, 4 jackscrews, 5 upper sliding sleeves, 6 upper umbrella rods, 7 jackscrews, 8 umbrella frame slides, 9 hinges, umbrella bar in 10,11 connecting rods, 12 outer pivoted housings, 13 basic sliding sleeves, 14 jackscrews, 15 locking caps, 16 ears collude strut, 17 opening ball cups, 18 lower umbrella rods, 19 little axles, 20 low sleeves, sliding sleeve in 21,22 hinges, 23 spacing pins, 24 have the pipe box core of limited ring groove, 25 have the hollow pipe box of hinge page or leaf sheet, 26 standing screws, 27 pads, 28 connecting rod axle beds, 29 guide rails or guide groove, 30 steel balls, 31 elasticity bayonet locks, pipe in the umbrella bar in 32, a 33 long bayonet lock, 34 torsion springs, 35 solid bearing pins, 36 outside connecting rods, 37 swing handles, 38 inside connecting rods, umbrella bar outer tube in 39,40 opening ball cup shells, 41 bulbs, core at the bottom of 42 ball cups, 43 riveting pins, 44 hinged blocks, 45 limiting stands.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, the jackscrew that unclamps upper sliding sleeve (5), basic sliding sleeve (13) and outer pivoted housing (12) makes upper sliding sleeve (5) and compound sliding sleeve (13,12) be in free state.As required certain angle is pulled back and be twisted into to the middle relatively umbrella bar (10) of upper umbrella rod (6), screw jackscrew (4,14) afterwards and make two sliding sleeves (5,13,12) fixing.Under the effect of the connecting rod (11) that is connected with two sliding sleeves (5,12), kept the relative status of upper umbrella rod (6) and middle umbrella bar (10) constant.The angle that needs will be pulled back again between lower umbrella rod (18) and the middle umbrella bar (10), fork ear with strut (16) colludes the standing screw (26) that tangles compound sliding sleeve (or big sliding sleeve ［ 20 ］) afterwards, and be fixed with locking cap (15), so promptly be the duty that the utility model improves eccentric umbrella.

Referring to Fig. 7, with compound sliding sleeve cunning in following twisted point and fixing, upper sliding sleeve and upper umbrella rod are fixed (when the limit opening of compound sliding sleeve makes screw thread into can with its nut and pad stubborn take off make outside pivoted housing break away from basic sliding sleeve and fix with middle umbrella bar.Upper sliding sleeve fixes with upper umbrella rod again) promptly become upright user mode.

In making referring to the duty of Figure 10, Figure 15, Figure 16, Figure 17, improvement eccentric umbrella control elasticity bayonet lock (31) or a long bayonet lock (33) and swing handle (37) in the umbrella bar pipe (32) and inside connecting rod (38) Telescopic Fixed.
