Figure 3 is another partial cross-sectional perspective view of the embodiment of Figure 1 coupled to a post and a slanted bar. detailed description

In order to more clearly understand the technical content of the present invention, the following embodiments are specifically described. It is to be understood that the examples are not intended to limit the invention.

Referring to Figures 1-3, the umbrella parachute labor saving mechanism of the present invention comprises a suspension beam 1, a drawstring 2, an elastic member 3 and a fixing block 4, the drawstring 2 comprising a first end portion 21 and a second end portion 22, the second end portion 22, the elastic member 3 and the fixing block 4 are all located in the cantilever beam 1, and the first end portion 21 passes through the end surface 11 of the cantilever beam 1, the first The two end portions 22 are fixed to the fixing block 4, and the elastic member 3 is located between the end surface 11 of the cantilever beam 1 and the fixing block 4 and abuts against the end surface 11 of the cantilever beam 1 and the fixing Block 4.

The elastic member 3 can be any suitable member. Referring to Figures 1-3, in a specific embodiment of the present invention, the elastic member 3 is a spring, and the spring is sleeved on the drawstring 2.

The fixed block 4 can be any suitable component. Preferably, the fixing block 4 is an end card. Referring to FIGS. 1-3, in a specific embodiment of the present invention, the drawstring 2 is a wire rope, and the end face card is a wire end face card, and the wire rope is stuck in the wire end face card. In order to facilitate displacement of the drawstring 2 relative to the cantilever beam 1, preferably, the parachute openwork labor saving mechanism further includes a drawstring support member 5, and the first end portion 21 surrounds the portion of the drawstring support member 5. The drawstring support member 5 can be any suitable structure. Referring to Figures 1-3, in a specific embodiment of the present invention, the drawstring support member 5 is a support block having a chute, The first end portion 21 is wound around a portion of the chute.

The slanted bar 10 of the umbrella and the post 20 can be secured by any suitable means. More preferably, the parasol umbrella labor-saving mechanism further includes a diagonal rod fixing block 6 , the pull cord supporting member 5 is disposed on the diagonal rod fixing block 6 , and the first end portion 21 is fixed on the The slant rod is fixed on the block 6. The slanting rod 10 is connected to the slanting rod fixing block 6, and the slanting rod fixing block 6 is fixed to the column 20.

The drawstring support member 5 may be mounted on the diagonal rod fixing block 6, or the drawstring support member 5 and the diagonal rod fixing block 6 may be integrally formed. Referring to FIG. 1-3, in a specific embodiment of the present invention, the support block with the chute and the diagonal rod fixing block 6 are integrally formed, that is, the chute is actually the diagonal rod fixing block 6. The raised chute, and preferably the variable radius.

The slanting bar fixing block 6 can be fixed on the upright 20 of the parasol by any suitable structure. Referring to FIG. 1-3, in the specific embodiment of the present invention, the parasol umbrella saving mechanism further includes The locking plate 7 is locked, and the slanting bar fixing block 6 is fixed to the upright 20 of the sunshade by the locking platen 7. The slanting rod 10 is connected to the slanting rod fixing block 6 through the slanting rod connecting head 30.

As shown in FIG. 1, the suspension beam 1 is installed between the two diagonal rods 10 supporting the umbrella frame, and the first end portion 21 of the rope 2 is wound around the sliding groove and mounted on the diagonal rod fixing block 6, the diagonal rod fixing block. 6 is fixed to the upright 20 of the sunshade by the locking platen 7. For example by tightening the screws.

As shown in Fig. 2, at this time, the open state, the spring in the cantilever 1 is in the initial state, and is regarded as the uncompressed storage force. Referring again to Figure 3, at this time, the umbrella is in a state of being closed. Since the wire rope is of a fixed length, as the inclined 4 dry 10 rotates downward toward the column 20, the wire rope will be more wound around the chute, for example, the wire rope is wound in FIG. The chute is nearly 1/4 turn, so the size difference is formed. The wire rope drives the end of the wire rope to compress the spring. At this time, the spring will produce a force opposite to the umbrella, but the spring force is less than the force required to open the umbrella. , can receive umbrellas normally. Conversely, when the umbrella is opened, this resilience will assist in the easy opening of the umbrella. The specific process is that the spring is deployed through the inner end of the wire rope end of the card to actuate the slanting bar.

In summary, the umbrella parachute labor-saving mechanism of the invention has the advantages of ingenious and unique design, clean structure, unfolding and labor saving, and does not affect the overall appearance, and is suitable for large-scale popularization and application.

In this specification, the invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and changes can be made without departing from the spirit and scope of the invention. Accordingly, the specification and figures are to be regarded as illustrative and not limiting.
