Abstract

The utility model relates to an improved structure of an umbrella frame which alters a clamping structure in a second section main frame to cause a flexible frame in the U-shaped groove-shaped second section main frame to penetrate through an elastic restricting slice fixed on the bottom surface or side surface by a rivet, and the effects of the smoothness, convenience and safety of umbrella fixing, opening and closing actions. The utility model is used for a four-fold umbrella frame.

Description

Structure improved umbrella frame

The utility model belongs to the parts of umbrella, relates in particular to a kind of structure improved umbrella frame.

Tradition umbrella rib structure such as Fig. 1 institute formula, it is coated on the main bone 12 of second joint with ring 1, the folding of control umbrella, though restricted to flexible bone, the overall width of umbrella after folding enlarges, its behaviour in service is not so good, and is not too smooth and easy.

The purpose of this utility model is to provide a kind of structure improved umbrella frame, smooth and easy when it is manipulated, convenient, safety.

The utility model adopts following technical scheme:

The structure improved umbrella frame of the utility model, each folding umbrella frame picks out first segment master bone respectively by main umbrella skeleton top and sliding part, the main bone of second joint, the 3rd main bone of joint and minor details master bone, one end of elastic limit sheet is fixed on the main bone of second joint as the U shape with rivet, there is a long slot bore allow in the other end of this elastic limit sheet to be connected to the pliability bone between first segment master bone and the main bone of the 3rd joint to pass, folding with each joint umbrella frame, this flexure strip lodges in the main bone of second joint, used rivet also can be fixed on the bottom surface, stage casing of the main bone of second joint, can also be fixed between the two sides, stage casing of the main bone of second joint.

Specifically narrate embodiment below in conjunction with accompanying drawing:

Among the figure, 1 ring, 11 first segment master bones, the main bone of 12 second joints, the main bone of 13 the 3rd joints, 15 elastic limit sheets, 151 long slot bores, 152 perforation, 16 rivets, 161 both sides faces, 17 elastic limit sheets, 171 elastic limit sheets, one stomidium, 172 long slot bores, 18 rivets, 19 flexible bones

First embodiment such as Fig. 1, shown in Figure 2, use is on the umbrella frame of four-folding, each four folding umbrella frame picks out first segment master bone 11 respectively by main umbrella skeleton top and sliding part, the main bone 12 of second joint, the 3rd main bone 13 of joint and minor details master bone, in the hole 171 that is fixed with an end of an elastic limit sheet 17 as second bottom surface, stage casing of saving main bone 12 of U shape with a rivet 18, there is a long slot bore 172 allow in the other end of this elastic limit sheet 17 to be connected to a flexible bone 19 of 13 in first segment master bone 11 and the main bone of the 3rd joint to pass, as shown in Figure 6, with the folding of each joint umbrella frame, this elastic limit sheet 17 can lodge in the main bone 12 of second joint.When as shown in Figure 7, each joint umbrella frame is opened, at this moment flexible bone 19 can outwards move and tension along with opening of umbrella, because margining tablet 17 other ends of the present utility model are by the lodging state, with the rivet fixing point is that fulcrum erects downwards, allows flexible bone 19 tensions on the outer side summit of long slot bore 172, limits flexible bone 19 and ejects outside the main bone 12 of second joint, the open smoothness of umbrella can be promoted like this, its free folding and unfolding can be made.

Second embodiment such as Fig. 4, shown in Figure 5, use is on the umbrella frame of four-folding, each four folding umbrella frame picks out first segment master bone 11 respectively by main umbrella skeleton top and sliding part, the main bone 12 of second joint, the main bone 13 of the 3rd joint, minor details master's bone, at 161 the perforation (not shown) of fixing an elastic limit sheet 15 1 ends with a rivet 16 of both sides, stage casing face that save main bone 12 as second of U shape, there is a long slot bore 151 allow in these elastic limit sheet 15 other ends to be connected to a flexible bone 19 of 13 in first segment master bone 11 and the main bone of the 3rd joint to pass, as shown in Figure 8, with the folding of each joint umbrella frame, this elastic limit sheet 15 can save in the main bone 12 second in lodging.When approximate shown in Figure 7, each joint umbrella frame is opened, at this moment flexible bone 19 can outwards move and tension along with opening of umbrella, because of elastic limit sheet 15 other ends of the present utility model by the lodging state, with the rivet fixing point is that fulcrum erects downwards, allows flexible bone 19 tensions on the outer side summit of long slot bore 151, limits flexible bone 19 and ejects outside the main bone 12 of second joint, can promote the open smoothness of umbrella like this, but free folding and unfolding.

Facts have proved, the structure improved umbrella frame of the utility model, reasonable in design, practicality overcomes the defective of traditional product, and easy to use, handling safety reaches design purpose.

Claims
