The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model easily folding automatic multifold umbrella comprise: be provided with the bone spring that closes one's umbrella umbrella frame assembly (not shown), middle excellent 1, umbrella head 2, be fixed on described middle excellent 1 top upper nest 31, be slidingly socketed in described middle excellent 1 lower nest 32 and automatic open-close device.Described middle excellent 1 comprises that a joint inner tube 11, that is slidingly socketed successively from the inside to the outside saves or with upper intermediate tube 12 and a joint outer tube 13, described inner tube 11 bottoms and described umbrella head 2 are affixed, and described outer tube 13 tops and described upper nest 31 are affixed.In the present embodiment, described automatic open-close device comprises: be installed in deployment spring in middle excellent 1, be installed in nest 31 places upper nest pulley 53, be located at lower nest 32 places lower nest pulley 54, backguy 55, be fixed in nest 31 bottoms on middle excellent 1 inner chamber sleeve pipe 56, sub warhead 57, be installed in control button 58 on the umbrella head 2 and keyholed back plate 59 etc.Described backguy 55 1 end connexon bullets 57, the other end is walked around nest pulley 53 after passing described sleeve pipe 56 inner chambers, and nest pulley 54 under the pile warp is fixed on the nest 31 at last again.Closed one's umbrella in the compression excellent 1 o'clock, described sleeve pipe 56 advances sub warhead 57 in the keyholed back plates 59 so that sub warhead 57 locked (such as Fig. 2) downwards.When pressing control button 58, perhaps compressed middle excellent 1 will be released and parachute-opening under the effect of deployment spring (such as Fig. 1), will be released into that umbrella frame is able to folding in middle excellent 1 inner chamber thereby perhaps be locked to sub warheads 57 in the keyholed back plate 59.Above structure is prior art, repeats no more herein.
Improvements of the present utility model are deployment spring parts wherein, and the below is described in detail as an example of triple folding umbrella example.As shown in figures 1 and 3, described middle excellent 1 is slidingly socketed successively from the inside to the outside and is formed by pipe 12 and one joint outer tube 13 in a joint inner tube 11, the joint, wherein, as shown in Figure 4, the upper portion side wall of middle pipe 12 is provided with outwards outstanding stop section 15, the top of pipe 12 is fixed with in one and fills in 6 in being somebody's turn to do, and these interior plug 6 axle center are located to offer one and can be held the center vertical core that described sleeve pipe 56 passes.Described deployment spring by 52 two sections on the first spring 51 and the second spring independently spring form, wherein said the first spring 51 is folded between the tube wall of outer tube 13 and middle pipe 12, and the top of this first spring 51 and described upper nest 31 bottoms or outer tube 13 tops offset, and its bottom offsets with described stop section 15.Described the second spring 52 is installed in described inner tube 11 and middle pipe 12 inner chambers, and the bottom of its top and described interior plug 6 offsets, and its bottom supports in the bottom of described inner tube 11.
As shown in Figure 4, the bottom of described outer tube 13 is snapped with the guide thimble 16 of an inside indentation of the mouth of pipe, and this guide thimble 16 is arranged in 15 belows, described stop section and closely is socketed in outside the pipe 12.As shown in Figure 6, each convex of both sides of described guide thimble 16 top sidewalls is provided with a fixture block 161, the top of described fixture block 161 is provided with the slide guide face, the both sides of outer tube 13 bottom sidewalls respectively have a bayonet socket 131, these outer tube 13 bottoms closely are socketed on described guide thimble 16 tops and described fixture block 161 just in time stretches out from described bayonet socket 131, these outer tube 13 bottom sidewalls also are provided with the salient point that concaves and just in time are stuck in the aperture 162 of offering on the described guide thimble 16 top sidewalls, outer tube 13 and guide thimble 16 can be snapped together thus.The first spring 51 can be wrapped in fully like this tube wall of outer tube 13 inner and can not expose, can also play a part correcting to sliding up and down of outer tube 13, outer tube 13 and guide thimble 16 are parts independently, convenient in excellent 1 assembling.As shown in Figure 2, the stop section of middle pipe 12 sidewalls more than 15 to should in the position at pipe 12 tops form the umbrella closing state lower excellent 1 accommodating space of described the first spring 51 when compressed.
As shown in Figure 5, described stop section 15 is for closely being socketed in the loop fasteners on described middle pipe 12 sidewalls, the top of pipe 12 is the larger circular cross-section of external diameter in being somebody's turn to do, the bottom is along the upper circular cross section toward the polygonal cross-section of interior indentation, becomes place, rank 123 so that the intersection, top and the bottom of middle pipe 12 forms one thus.Should in pipe 12 become rank and locate the radially both sides of 123 bottoms and be provided with two perforates 121, the bottom of each perforate 121 respectively is provided with a projection 122, described protruding 122 are provided with the slide guide face in the side away from perforate 121.During assembling, with loop fasteners 15 along in pipe 12 sidewalls upwards sliding and utilize the elasticity of loop fasteners 15 self to cross by force described protruding 122, final so that described loop fasteners 15 just in time is stuck between the place, change rank 123 and protruding 122 of described perforate 121 upper and lower parts, and the inwall of loop fasteners 15 and middle pipe 12 sidewalls closely cooperate.Under deployed condition, the bottom of the top of described guide thimble 16 and described stop section 15 offsets and can make it can not continue upward sliding to outer tube 13 location thus.In addition, the lateral wall of loop fasteners 15 just in time offsets with outer tube 13 inwalls, can play a part correcting to outer tube 13.Certainly, other versions can also be adopted in described stop section 15, such as, can manage 12 the outside punching press of tube wall by centering and form outside projection.
Automatic multifold umbrella of the present utility model also can be applicable to the above multi-fold umbrella of three foldings, such as: when being applied to the four fold umbrella, described the first spring 51 is installed in outmost 2-section pipe intracoelomic cavity, and described the second spring 52 is installed in innermost 2-section pipe intracoelomic cavity; When being applied to five folding umbrellas, described the first spring 51 is installed in outmost 2-section pipe intracoelomic cavity, and described the second spring 52 is installed in the inner chamber of all the other three-joint pipe bodies ... by that analogy.Its deployment spring of automatic multifold umbrella of the present utility model is divided into independently two sections, every section needed elastic force of spring is less than existing one-part form deployment spring, and the length ratio of the required compression of each section spring when closing one's umbrella is significantly smaller than the reduction length ratio of existing employing one-part form deployment spring, when closing one's umbrella thus in the compression the required strength of rod also greatly reduce, can be reduced to the 3-4 kilogram, feel very light and handy, this greatly facilitates the user, and especially the elderly and infirm uses.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
