The umbrella frame device 2 includes: a parietal bone 21 pivotally connected to the upper nest 20 located at the upper end of the middle stick 1; a lower support bone 22, the inner end of which is pivotally connected to the lower nest 20r, which slides on the umbrella middle stick 1, and a middle bone 23, Its innermost end 231 is pivotally connected to the parietal bone 21 by an inner connecting bone 25, while its inner end 232 is pivotally connected to the outer end of the lower ramus 22, and an elastic connecting bone 24 is slid on the middle bone 23. The outer end 233 of the middle bone 23 and the outer end 242 of the elastic connecting bone 24 are respectively pivotally connected by a coccyx 26 through a joint 27 fixed thereto.

Because it constitutes a three-fold multi-fold umbrella, of course the utility model can also be modified and applied as a multi-fold umbrella with other folds, and the utility model is not limited.

The cross-section of the lower ramus 22 forms a groove structure that is wide at the top and narrow at the bottom (or wide at the inside and narrow at the outside), which includes: a wide groove 22w and a narrow groove 22n communicating with the wide groove 22w.

In the present utility model, a spring device 3 is arranged in the middle of each lower support bone 22, and the spring device 3 includes: a spring 31, whose inner spring end 311 is tied to the lower nest 20r, and is connected to the lower nest 20r with a long rod 32. The outer spring end 312 of the spring 31 (as shown in FIG. 5 ). The spring 31 is slidably disposed in the wide groove 22w of the lower ramus 22 , while the long rod 32 is slid in the narrow groove 22n of the lower ramus 22 in its entirety or most of its outer rod.

The inner rod end 321 of the long rod 32 is affixed or crimped by the outer spring end 312 of the spring 31, and the outer rod end 322 is a free end that is adjacent to the outer end of the lower ramus 22 and is pivotally connected to the inner side of the middle bone 23. At the end portion 232 , the outer rod end 322 passes through a chute 22 s of the lower ramus, and a protruding hook portion 323 is protruded outward to connect with the inner end 241 of the elastic connecting bone 24 .

The middle bone 23 can be made of plastic (including reinforced plastic or plastic composite material) by injection molding and other molding methods, and the inner partition 23a and the outer end 233 are arranged horizontally adjacent to the inner end 232 and the outer end 233 respectively. The outer partition 23b is used to limit the elastic connecting bone 24 and slide into the main groove 23i at the bottom of the middle bone 23 .

Generally speaking, the bottom of the middle bone 23 forms a main groove 23i and the back forms a shallow groove 23t, as shown in FIG. 4 . Adjacent to the lower ramus 22 and the internal connecting bone 25, an internal partition 23a is transversely connected to the bottom of the middle bone (as shown in Figure 3); and adjacent to the coccyx 26, an external partition is transversely connected to the bottom of the middle bone 23 23b, the elastic connecting bone 24 can be slid in the main groove 23i of the middle bone 23 through this structure, and the inner and outer ends 241, 242 of the elastic connecting bone 24 are the inner and outer partitions 23a, 23b limited, as shown in Figures 1 and 6. And the shallow groove 23t on the back of the middle bone fits the coccyx 26 when closing the umbrella.

The joint 27 to which the inner end 261 of the coccyx 26 of the utility model is fixedly connected comprises: an axis portion 272 pivotally connects the axis portion 272 of the joint and the tail end 233 which is split with the middle bone by means of an axis pin 272p; The moving portion 271 is pivotally connected to the joint biasing portion 271 and the outer end 242 of the elastic connecting bone 24 by a biasing pin 271P.

The joint 27 can be integrally formed by plastic molding into a slightly P-shaped plate, pivotally connected to the fork-shaped middle bone tail end 233 by the pivot pin 272p, and the deflection part 271 is elastic by the deflection pin 271p. The outer end 242 of the connecting bone 24 is eccentrically rotated and driven to be in the umbrella retracting state in FIG. 1 or in the umbrella opening state in FIGS. 6 and 9 . The joint 27 has a straight end edge 270, which just blocks the top plate 23p of the groove of the middle bone 23 when the umbrella is opened, as shown in Figure 11; The outer end 242 of the elastic connecting bone 24 can be accommodated during this time, as shown in FIG. 1 .

The "secret" of the present utility model lies in the construction of the joint 27. When the umbrella is closed to open the umbrella, the lower nest 20r rises, and the ribs of the umbrella rib device 2 are stretched and unfolded. Among them, the middle rib 23 is stretched outwards by a parallelogram-shaped "connecting rod device" (consisting of umbrella ribs 21, 22, 23, 25), so that it is approximately straight and horizontal (Fig. 6, 9), and slides on the The elastic connecting bone 24 in the middle bone 23 is flexed and arched (Fig. 6-8) to accumulate its elastic energy, and the coccyx 6 and the connected head 27 are arched to form the outer end 242 of the elastic connecting bone 24. The deflection of the elastic force will quickly flatten and be in a straight line with the middle bone 23 (as shown in Fig. 6 to Fig. 9). In this way, when the traditional multi-fold umbrella is opened, the cumbersome and inconvenient actions of moving and leveling the umbrella cloth can be omitted. umbrella.

Secondly, the inner and outer partitions 23a, 23b, etc. of the middle bone 23, except that the middle part of the elastic connecting bone 24 is slidably restricted in the main groove 23i of the middle bone, and only the inside of the two ends of the connecting bone are allowed to slide. The end and the outer end are "exposed" to respectively connect the spring device 3 and the coccyx joint 27, and the two partitions 23a, 23b are horizontally connected between the longitudinal main groove 23i of the middle bone 23, and have the effect of reinforcement. It ensures the durability of the rib unit.

The wide groove portion 22w of the lower support bone 22 can accommodate the parietal bone 21 and the inner connecting bone 25 when the umbrella is retracted, and the narrow groove portion 22n can be accommodated in the main groove 23i of the middle bone 23 when the umbrella is retracted. Among them, the folded volume is greatly reduced, making the multi-fold umbrella miniaturized and easy to carry. And the narrow groove portion 22n of the lower branch bone coincides with the main groove of the middle bone 23 when closing the umbrella, so that the umbrella bone is not easy to twist and deflect, and has the function of "guiding". This also makes the umbrella open when the umbrella is opened. The power of the umbrella is exerted smoothly without any deviation, which is also helpful for the rapid opening of the parachute.

Discuss this spring device 3 again when opening the umbrella, the umbrella ribs are opened, so that the coccyx 26 pulls the long rod 32 of the elastic connecting bone 24 and the spring device 3, and the long rod protruding hook 323 is along the chute of the lower ramus 22s sliding, stretching spring 31, so the elastic force when accumulating the umbrella is also helpful to quickly retract the umbrella, so although the utility model is called "quickly opening the umbrella", it actually has the double function of "quickly retracting the umbrella" . And this spring device 3 is in the parachute-opening process, because of this elastic connecting bone 24 and the coccyx 26 outside the long rod 32, when opening the umbrella process, the elastic connecting bone 24 is once subject to the phenomenon of flexing and arching. The outer end 242 of the joint bone 24 pushes the joint 27 of the coccyx 26, while the inner end 241 of the joint bone 24 is tied to the long rod 32, and the long rod 32 is connected with the spring 31, which is equal to using the spring 31 as a back cushion to make the opening During the umbrella process, the friction between the related ribs and the components is reduced to avoid noise, and because of the buffer of the spring 31, the force of opening the umbrella is relatively smooth, which also indirectly contributes to the quick opening of the umbrella.

The above description is also applicable to the process of retracting the umbrella, so that the utility model can retract the umbrella quickly, smoothly, effortlessly, and without noise.

The spring 31 in the spring device 3 is slidably arranged in the groove at the inner end of the lower ramus 22, and only allows the slender rod 32 to slide in the narrow groove 22n at the outer end of the lower ramus without disturbing the opening. 1. In the process of closing the umbrella, the pivot joints [the outer ends of the lower ramus 22, the inner end of the middle bone 23 and the inner connecting bone 25 outer ends] of the more frequently contacted umbrella ribs make the operation smooth.

What must be mentioned is: as shown in Fig. 9 and 11 when opening the umbrella (full opening), the elastic connecting bone 24 is not completely in a straight line and the connecting line L2 between its center line (L1) and two pins 271p, 272p is non-linear. On the same straight line, in this way, when the umbrella is retracted, the outer end 242 of the connecting bone 24 can deflect the deflection part 271 of the joint 27 clockwise, and from Fig. 9, 11 to Fig. 6 , 8 (reverse "Reverse" operation of the aforementioned parachute opening action), and then to the parachute closing state of Fig. 1 . Otherwise, if L1 and L2 merge into a straight line, there will be a "dead angle" and the umbrella cannot be retracted.

The utility model can be appropriately modified or changed without violating the spirit and scope of the creation, and the utility model is not limited thereto.
