Description

The present invention relates to a folding umbrella automatic opening / closing device, and more particularly, to an umbrella opening / closing control device applicable to a multi-stage folding umbrella having four or five folds.

  The present automatic folding umbrella automatic opening / closing device controls an umbrella bone assembly and an umbrella surface folding pivoted between an upper nest and a lower nest by pressing an umbrella control device. As disclosed in “Utility Control Device for Multi-Stage Automatic Opening and Closing Umbrella” in Chinese Utility Model No. 0120334.2 by the applicant, the control device mainly has a button that is slid in the control handle. Then, after the ring-shaped part where the middle part of the button is stretched is seized, when the middle bar is in a compressed state, it engages with the cut tank in the control pattern of the lower nest, and first presses the ring-shaped part of the button to release the lower nest. The opening elastic spring in the middle bar improves the lower nest and opens the umbrella. Next, when the button is pressed, the umbrella control element rises, the convex body of the button is pressed into the umbrella control column of the umbrella control element, and the staircase of the umbrella control seat is moved to the umbrella control seat. It pushes to the center, disengages the connection and consolidates, and achieves the opening and closing two-stage control function.

However, the above-described known three-stage automatic opening / closing device has the following drawbacks in actual use.

1. When the middle bar is in the compressed state, the staircase connected to the umbrella control seat is located at the upper part of the control handle, and the lower end of the opening elastic spring is also located at the upper part of the control handle. When the space for holding the opening spring is small, and the multistage umbrella with automatic opening and closing is folded in four or five, the opening elastic spring becomes insufficiently elastic due to the restriction of the length. It is difficult to apply to a five-fold jump umbrella.
2. There are many components of the existing multi-stage automatic umbrella opening and closing device, and the structure is complicated, the degree of processing is high, the manufacturing cost is high, and the control buttons are difficult to operate.

An object of the present invention is to provide an automatic opening / closing device for a folding umbrella which improves the above-mentioned problems.

The automatic opening and closing device for folding umbrellas of the present invention is an automatic opening and closing device that can be used for multi-stage umbrellas with four or five folds by increasing the length space to accommodate the opening elastic spring of the middle stick and increasing its elasticity. Device.

The present invention is a multistage automatic umbrella opening / closing device that has a simple structure, is easy to manufacture, and is labor-saving for the user.

Button guide tanks 913 are recessed in the inner walls on both sides of the opening, the lower part of the handle body 91 is provided with an engaging hole 911 for engaging the lower end of the lower pipe 11, and a rising spring 943 is engaged in the upper part of the engaging hole 911. A concave surface hole 916 having a large diameter is provided, a passage tank 917 for accommodating the side wall and the sliding top plate 93 is in communication with each other, and the outer side of the passage tank 91 has a cover 95 corresponding to the button opening.

  As shown in FIG. 4, the button 92 is an annular frame, and both outer frame edges fit into the button guide tanks 913 on both sides of the cavity body 912 and slide, and the outer end is similar to the outer wall of the handle body 91. A pressing portion 921 having an arc degree is provided, a convex portion 923 coupled to one end of a return spring 925 is provided at the bottom end, a chain-convex convex base 924 that forms an inclined surface toward the inner side, and an upper tube 13 is fixed.

  As shown in FIG. 5, the peristaltic top plate 93 has a locking portion 932 that links the shaft 931 from the middle to the tank 917 of the handle 91 and is linked to the staircase 81 on one side of the lower stage. At the other end, a protrusion 933 engaging with one end of the thrust spring 935 is installed, and the upper stage penetrates the movable element 94 and corresponds to the swing arm 934 of the pressing portion 921 of the button 92.

  As shown in FIG. 6, a stereotaxic tank 942 in which a long hole 941 that coincides with the moving direction of the button is installed at the center of the movable element 94 and a peristaltic arm 934 on the top of the peristaltic top plate 93 is fitted into one end of the long hole 941. Is recessed.

  The upper nest 2 is fixed to the top end of the upper tube 13, pivots an upper pulley that exposes the outside in the lower end side wall, and penetrates a fixing hole on the top end side.

  The lower nest 3 is installed outside the upper tube 13 and pivots a lower pulley on the top end side.

  The pair of umbrella bone assemblies 4 are connected between the upper nest 2 and the lower nest 3, and an umbrella spring 5 is installed between the umbrella bone assemblies 4.

  The elastic inner tube 6 is a hollow tube coupled inside the lower tube 11.

  The opening elastic spring 7 is installed in the space between the elastic inner tube 6 and the lower tube 11, the upper end is in contact with the upper end of the elastic inner tube 6, and the lower end is controlled by the top surface of the opening elastic spring seat 71.

  The tension rope 8 is drilled inside the elastic inner tube 6 and is connected to a staircase 81 provided at the tail end and the lower end of the elastic inner tube 6, and the other end connects the upper nest 2 upper and lower nest 3 lower pulleys. It is pierced and fixed to the fixing hole at the top end of the upper nest 2.

  The staircase body 81 is a convex body and is placed in the opening elastic spring seat 71, corresponds to the restraining portion of the sliding top plate 93, and the top portion and one end of the tension rope 8 are connected.

  Referring to FIGS. 1 and 2, after the umbrella is retracted, the middle bar 1 is compressed, the convex base 924 of the button 92 falls into the concave position 131 below the upper tube 13, and the upper tube 13 is chained. The intermediate rod 1 is maintained in a compressed state. At this time, the movable element 94 is pushed downward by the bottom end of the intermediate tube 12 and is released from the button 92, and the staircase 81 of the tension rope 8 is engaged with the top plate 93. It is chained by the section 932 and reaches the folded umbrella state.

  As shown in FIG. 7, the pressing portion 921 of the button 92 is first pressed to move the button 92 inward, and the movable element 94 and the button 92 are opened. Therefore, when the button 92 shifts inward, it contacts the sliding top plate 93. Without the convex base 924 leaving the concave position 131 at the lower part of the upper tube 13, the chain is released from the upper tube 13, and the middle rod 1 is not chained. , And the center rod 1 opens and forms an open umbrella state. At this time, the staircase body 8 is chained by the peristaltic top plate 93, tightens the tension rope 8, the lower nest 2 does not slide down, and the movable element 94 moves upward by the action of the spring 943.
