Description

The automatic umbrella rib shelf structure of many foldings

The utility model relates to the structure of the automatic umbrella rib frame of a kind of many foldings.

The structure that closes one's umbrella of the automatic umbrella of various many foldings, usually between second umbrella frame 2 and umbrella gill 4, be provided with a spring 6, make automatic umbrella when closing one's umbrella, utilize the restoring force of this spring 6, the umbrella frame bending is recovered as folding umbrella attitude, as shown in Figure 1, it is the inner end positions that an end of spring 6 is connected in second umbrella frame 2, the other end of spring 6 then is connected in the outer end position of umbrella gill 4, approaches the curved side of the pliability bone 5 inner umbrella gills that are fastened on 4, when closing one's umbrella, the answer pulling force of spring 6, make umbrella gill 4 interlock pliability bones 5 and the 3rd upwards bending of fulcra 3, form the folding umbrella structure after closing one's umbrella automatically, this kind structural design is because spring 6 has a spacing with pliability bone 5, when the application of force, produce a cross component force, will make that the action that closes one's umbrella is comparatively not smooth.In addition, it must offer two combined holes on umbrella gill 4, connects spring 6 respectively and fastens pliability bone 5, so, has reduced the intensity of umbrella gill 4, makes it more fragile.

The purpose of this utility model provides a kind of automatic umbrella rib shelf structure of many comparatively smoothly foldings that closes one's umbrella.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

Basic structure of the present utility model is with common identical, the setting that it is characterized in that spring is with common different, the inner of spring of the present utility model be located in the place, the inner of second umbrella frame, and the outer end then is fastened on the combined hole of umbrella gill, promptly has the same closed position that is connected with the pliability bone.Therefore, when spring was replied contraction, its pulling force was delivered to pliability bone place automatically, and under the effect of component, drive the 3rd umbrella frame and umbrella tailstock group easily upwards, form the action that closes one's umbrella automatically, it is comparatively smooth to close one's umbrella, simultaneously, offer a combined hole on the umbrella gill less, improved the intensity of umbrella gill.

The utility model will be further described below in conjunction with embodiment:

Fig. 1 is the retainer spring combination assumption diagram of the automatic umbrella rib frame of common many foldings.

Fig. 2 is the combination assumption diagram of the utility model retainer spring.

Fig. 3 is a parachute-opening floor map of the present utility model.

Fig. 4 is the floor map that closes one's umbrella of the present utility model.

1 is that first umbrella frame, 2 is that second umbrella frame, 3 is that the 3rd umbrella frame, 4 is movable nest for last nest, 72 for rod in the umbrella, 71 for spring, 7 for pliability bone, 6 for combined hole, 5 for umbrella gill, 41.

See also Fig. 2, Fig. 3, shown in Figure 4, the utility model embodiment is an example with four folding umbrellas, include rod 7 in the umbrella, go up basic structures such as nest 71, movable nest 72, retainer spring 6, the inner of first umbrella frame 1 and last nest 71 are articulated, the outer end is connected with second umbrella frame 2, the 3rd umbrella frame 3 and umbrella tailstock etc. in regular turn, and the inner of umbrella gill 4 is connected with at movable nest 72, and the outer end then is articulated in the inner end positions of the 3rd umbrella frame 3, and close hole 41 being provided with a tangerine near the articulated section, to connect the inner that fastens pliability bone 5.

Feature of the present utility model is the setting of retainer spring 6, and the inner of retainer spring 6 be located in the place, the inner of second umbrella frame 2, and the outer end of spring 6 then is fastened on the combined hole 41 of umbrella gill 4, promptly has the same closed position that is connected with pliability bone 5.Therefore, when spring 6 was replied contraction, its pulling force was delivered to pliability bone 5 places automatically, and under the component effect, drove the 3rd umbrella frame 3 and umbrella tailstock group easily upwards, formed the action and the state that close one's umbrella automatically.

The utility model is directly delivered to pliability bone 5 because of the restoring force that spring 6 is produced, so, can finish the smooth-going action that closes one's umbrella easily, do not have the blocking phenomenon and take place.In addition, because of 4 of umbrella gills are offered a combined hole, therefore, increased the intensity of umbrella gill 4 relatively.

Claims (1)

1, the automatic umbrella rib shelf structure of a kind of many foldings, it includes rod (7) in the umbrella, last nest (71), movable nest (72), the upper end of rod (71) is last nest (71) in the umbrella, and sheathed movable nest (72), its each umbrella frame and umbrella gill are respectively by the connection that stretches out of last nest (71) and movable nest (72), spring (6) is located between second umbrella frame (2) and the umbrella gill (4), it is characterized in that: the inner of spring (6) be located in the place, the inner of second umbrella frame (2), and the outer end of spring (6) is fastened on the combined hole (41) of umbrella gill (4), and the outer end closed position of spring (6) is identical with the connection closed position of pliability bone (5).
