Description
The present invention relates to the Antikink device of the umbrella frame of umbrella, particularly prevent bending as described below, it is the umbrella of softened state, its main umbrella skeleton front end expose collision such as umbrella frame one side and ground, flooring, trees and building the time bending that takes place, mainly be the bending that takes place of the outside left in main umbrella skeleton and coupling part supporting umbrella bone (crooked, bend, fracture, crook etc.).
The umbrella frame of umbrella comprises: 8 main umbrella skeletons, their end axles prop up and are being fixed in the buckleing on the pin (Network mouth suitable for reading) of umbrella axle upside, and multiple umbrella cloth is opened in the outside; 8 supporting umbrella bones, but on the coiled hair cover (end opening Network mouth) of their the chimeric free lifting of an end axle Zhi Zaiyu umbrella axle, the other end is connected with the middle part of each main umbrella skeleton, from each main umbrella skeleton of inboard supported underneath.Main umbrella skeleton and supporting umbrella bone all are metal.
Main umbrella skeleton is connected usually as shown in Figure 9 with supporting umbrella bone, the connector B of setting-in metal in the U font groove of the middle part of main umbrella skeleton A (slightly near the umbrella axle), with the end axis of supporting umbrella bone prop up connection in this connector B with protruding B2 on.
Specifically be, in the length that bends to the U font of the connector B roughly middle part of short pin sheet B1, convexed to form the protruding B2 of a pair of connection at certain intervals in opposite directions, the connection of pin sheet B1 is fixed by riveting C and main umbrella skeleton A with two outside lefts of protruding B2.
A pair of connection is with offering small sircle hole on the protruding B2, and a pair of connection is inserted with between the protruding B2 in the end of supporting umbrella bone, by small sircle hole with the end axis of supporting umbrella bone prop up in a pair of connection with protruding B2 on.
When unfurling an umbrella, the coiled hair cover rises along the umbrella axle, going up by spring makes coiled hair overlap the fixed-site of no longer decline thereby supporting umbrella bone, main umbrella skeleton is to be supported from the below by supporting umbrella bone, remain on softened state, but under this state, if main umbrella skeleton is applied the external force of exposing umbrella frame side direction root (umbrella axle side) direction from its leading section, because supporting umbrella bone is in stationary state, supporting umbrella bone can work through the coupling part, main umbrella skeleton is pushed laterally, therefore, can concentrate on the position that is connected with supporting umbrella bone of main umbrella skeleton this moment from the leading section one side externally applied forces (impulsive force) of main umbrella skeleton.Like this, because the tension force of the umbrella cloth of its fixed outside, main umbrella skeleton becomes decurved state, and the umbrella frame that exposes of main umbrella skeleton front end becomes the direction of directed towards ground as far as possible.
Therefore, umbrella is under situation about strutting, if owing to being flown by wind or reason such as throwing, collide at expose the umbrella frame position and road surface or flooring of main umbrella skeleton front end, perhaps owing to do not note waiting when making collisions such as exposing umbrella frame part and trees, building, its impulsive force is concentrated the connecting portion that acts on main umbrella skeleton and supporting umbrella bone, main umbrella skeleton will take place from this position or from size the exposing of pin sheet B1 of short connector bone one side be that outside left bends (bending, bending, fracture, crook etc.) the such state of affairs of cakes with moulded designs.
Therefore, the objective of the invention is to, prevent that reliably the Western-style umbrella of above-mentioned softened state from exposing the main umbrella skeleton bending accident that might take place when the umbrella frame side is subjected to impacting, to improve the durability of umbrella frame.
In order to achieve the above object, the invention is characterized in, in the U font groove of main umbrella skeleton and connecting portion supporting umbrella bone, the reinforcement that connects usefulness and main umbrella skeleton enhancing usefulness with the state setting-in supporting umbrella bone of its inner space of dense pack, this reinforcement is with by glass fibre, carbon fiber, the clava of the Len req that fiber-reinforced resins such as fluorine fiber form is connected the connection of usefulness with supporting umbrella bone one-body molded with raising into, and in this claval outside, the bulge of protrusion formation along its length forms, the claval Len req of above-mentioned reinforcement connects long with connector than traditional supporting umbrella bone, promptly set sufficient length, when umbrella rib when it exposes umbrella frame one side and is subjected to impacting, this length can make and concentrate on the impulsive force with connecting portion supporting umbrella bone main umbrella skeleton and diminish as far as possible at claval front end position.
Since in the U font groove of main umbrella skeleton and connecting portion supporting umbrella bone setting-in is connected clava in the longer reinforcement of usefulness connector B than traditional supporting umbrella bone, promptly, clava is set at enough length, with convenient main umbrella skeleton when exposing umbrella frame one side and be subjected to impacting, the impulsive force of the connecting portion that concentrates on main umbrella skeleton and supporting umbrella bone is diminished as far as possible at claval fore-end, this clava is inlaid in the U font groove of main umbrella skeleton and is its inner space of fine and close state filling, and be to make, have suitable hardness and elasticity by the fiber-reinforced resin of glass fibre etc.Therefore, when the main umbrella skeleton of umbrella was exposing a side and is hit, based on the structure of umbrella frame, excessive impulsive force was concentrated the connecting portion that acts on main umbrella skeleton and supporting umbrella bone, but this excessive impulsive force to the effect of main umbrella skeleton than traditional obviously reducing.
Because in traditional approach, supporting umbrella bone connects with connector B length shorter, be that the cross section identical with main umbrella skeleton is the foil of U font, do not fill the space segment in the main umbrella skeleton U font groove, lack absorption impulsive force performance, so the above-mentioned excessive impulsive force that concentrates on the connecting portion of main umbrella skeleton and supporting umbrella bone not only acts on the connecting portion of main umbrella skeleton and supporting umbrella bone, and act on the outboard end of exposing of connector B, also similarly act on main umbrella skeleton with much at one pressure.Therefore in traditional approach, the outboard end of exposing that is subjected to the connector B of almost onesize excessive impact force action produces resistance, and main umbrella skeleton fractures at the location bending of this end easily.
And in the present invention, the clava of reinforcement is inlaid in the U font groove of main umbrella skeleton with the state of the space segment in the dense pack U font groove, main umbrella skeleton and reinforcement are combined into one, and the absorbent properties of used material impact power are very strong, moreover, because as mentioned above, the claval length of reinforcement is set to longer than the length of traditional connector B defined, the claval position that suitable distance is arranged at the connecting portion between main umbrella skeleton and supporting umbrella bone near the position, top of exposing umbrella frame one side, so, even excessive impulsive force concentrates on the connecting portion between main umbrella skeleton and the supporting umbrella bone, this impulsive force also can fully be absorbed and be relaxed, simultaneously, act on the claval pressure that produces near the impulsive force of the fore-end that exposes umbrella frame one side little more than traditional structure, therefore different with traditional structure, main umbrella skeleton is not easy to occur at the front end position near exposing umbrella frame one side of holding in both hands the shape body bending accident that fractures.

The cross sectional shape of the clava 2a of reinforcement 2 is adapted to the hollow space in the U font groove of main umbrella skeleton 1 is filled fine and close as shown in Figure 3.Connect widelyer slightly than the width of visiing shape body 2a, when being inlaid in reinforcement 2 in the main umbrella skeleton 1, connecting both sides bottom surface sections with protruding 2b and be divided into state by position mounting above U font groove two lateral plates of main umbrella skeleton 1 with the width of protruding 2b.
As shown in Figure 1 and Figure 2, reinforcement 2 setting-ins are gone in the main umbrella skeleton 1, be by with the exposing umbrella frame side fore-end and connect the riveted joint (3a, 3b, 3c) that bends inwards respectively of two lateral plates with the main umbrella skeleton 1U font groove at position, protruding 2b both sides and carry out of reinforcement 2, thereby main umbrella skeleton 1 and reinforcement 2 are fixed.2f is holding in both hands the gap slot that is provided with on the shape body 2a for the adaptability of improving 1 distortion of 2 pairs of main umbrella skeletons of reinforcement, is not provided with good.
The connector 5 that is divided into two bifurcateds is fixed in an end of supporting umbrella bone 4, it is also hinged by small sircle hole that two bifurcateds of this connector 5 clip two lateral surfaces that connect with protruding 2b, so supporting umbrella bone 4 is connected with main umbrella skeleton 1, and can rotate relative to main umbrella skeleton 1.
In addition, also can be divided into two with protruding 2b on the contrary with connecting, with make flat connector the end or become the connection end of the supporting umbrella bone 4 of flat to be clipped in wherein hinged equally.
Fig. 6-Fig. 8 has shown that reinforcement 2 has other embodiment of some changes.Fig. 6 is an example of not establishing the bulge 2d in the foregoing description, and Fig. 7 is an example of also establishing gap slot 2g, 2h with two Outboard Sections of protruding 2b connecting, and Fig. 8 does not establish gap slot, and forms the example of bulge 2c, 2d at the whole length direction of clava 2a.
Structure of the present invention as above has following effect.
(1) in traditional Western-style umbrella, to be than short cross section the U font, on its metal system pin sheet, be provided with the connector that is connected the projection of usefulness with supporting umbrella bone and be inlaid in metal cross section and be in the main umbrella skeleton of U font, hinged supporting umbrella bone on this connector so that main umbrella skeleton be connected with supporting umbrella bone.
Therefore, traditional Western-style umbrella is in softened state, because of wind or reason such as do not note, on a side and the road surface of exposing umbrella frame, the flooring, trees, when buildings etc. bump, or the positive high wind of antagonism is when keeping softened state, because connector is the identical cross sectional shape of U font groove with main umbrella skeleton, and the inner space is not by dense pack, the absorbability that lacks impact power, and because length is shorter, impulsive force that main umbrella skeleton is subjected to or pushing force and from supporting umbrella bone, the pushing force that main umbrella skeleton is acted on laterally interacts, make it concentrate the connecting portion that acts on supporting umbrella bone, the distance of adding the riveting portion that makes the connector that main umbrella skeleton dies down and supporting umbrella bone connecting portion is very near, this connecting portion and peripheral part thereof, particularly connector expose the umbrella frame side, the bad like this state of affairs of bending takes place easily.
This for the tensioning of strengthening umbrella cloth in order to improve decorative effect, main umbrella skeleton by big macrobending, expose the more umbrella of directed towards ground of umbrella frame, problem is big especially.
And in the present invention, in the U font groove of main umbrella skeleton and connecting portion supporting umbrella bone and periphery, be embedded with the handful shape body that forms Len req with the fiber-reinforced resin of glass fibre etc., constitute reinforcement.The cross section is that the main umbrella skeleton of U font very thin thickness is subjected to the external force effect at length direction, occur bending and deformation in horizontal plane, right angle orientation such as vertical easily, above-mentioned reinforcement still becomes zoarium (closely chimeric) with main umbrella skeleton owing to be filled into the inner space part of the U font groove of main umbrella skeleton densely during distortion.And, the clava of reinforcement is not the short like that size of traditional connector, and have than traditional longer Len req, promptly, it has enough length, when umbrella frame when it exposes umbrella frame one side and is subjected to impacting, can make to concentrate on the impulsive force with connecting portion supporting umbrella bone main umbrella skeleton and diminish as much as possible at the fore-end of holding in both hands the shape body, owing to the relation of its material, it has suitable hardness and elasticity simultaneously.
Therefore, want the present invention because the clava of reinforcement is seated in the U font groove of main umbrella skeleton in the mode of dense pack U font groove inner space, be combined into one with main umbrella skeleton, and relation because of its material, so the absorbent properties of impact power are than traditional being significantly improved, and because its claval length is than traditional length, the impulsive force that its leading section is subjected to is obviously littler than traditional, so, the unfavorable condition that can reliably prevent traditional umbrella and produced, that is, can reliably prevent to bend at the outside left that closely exposes the umbrella frame end of the coupling part of main umbrella skeleton and supporting umbrella bone.
Owing to be provided with bulge (upward grand part) along its length in claval outside, more increased the intensity of reinforcement this moment as mentioned above, so, more can expect the reliability of its effect.
(2) because the integrated with it projection that is connected usefulness with supporting umbrella bone is arranged on reinforcement, when so the main umbrella skeleton supporting umbrella bone connects, as long as on main umbrella skeleton, load onto this reinforcement, needn't load onto the member of other connection supporting umbrella bone, can simplify the operation that is connected of main umbrella skeleton and supporting umbrella bone as much as possible, make things convenient for the manufacturing of Western-style umbrella.
(3) because the raw material of reinforcement is the fiber-reinforced resin of glass fibre etc., so it is not only extremely strong tough, and it is in light weight, add reinforcement and not only strengthen main umbrella skeleton, and be also used as connecting elements with supporting umbrella bone, even so load onto reinforcement, the weight of Western-style umbrella can not increase yet, be suitable for using.
(4) riveted joint place that is connected with reinforcement of main umbrella skeleton under the situation that is provided with 3 places as mentioned above, can further improve the close attached property of main umbrella skeleton and reinforcement as long as just enough at two places of holding in both hands shape body two ends, is very suitable.At this moment, even the connection of concentrating in impulsive force is provided with riveted joint place with the protruding side Outboard Sections that exposes, as previously mentioned, because the absorbent properties of the clava impact power of reinforcement obviously are better than traditional structure, so can not reduce the intensity of this part main umbrella skeleton and reinforcement.
