Description

Repeated self-opening and self-closing umbrella

technical field

The invention relates to an umbrella, in particular to an umbrella which can be opened and closed by one hand.

Background technique

The single-handed self-opening and self-closing umbrellas currently available on the market need to store energy in advance with the help of springs or external forces to realize self-opening and self-closing. The structure is complex and the production cost is high. Especially, once the energy is stored, it can only be opened and closed once. User-friendliness could not be better.

Contents of the invention

The purpose of the present invention is to provide a more convenient umbrella that can be opened and closed repeatedly without storing energy in view of the shortcomings and deficiencies in the background technology.

The technical scheme of the present invention is conceived and completed under a new concept completely different from the conventional umbrella opening and closing concept. It is composed of umbrella pole, long rib, short rib, upper plate, lower plate, handle and other main components. The umbrella pole is a hollow tube, and the upper plate and the lower plate are set on the umbrella pole, can slide, and are connected with the long rib and the short rib respectively. The long rib and the short rib link to form an acute angle. The feature is that the upper plate and the lower plate slide towards each other, and the umbrella starts to close; the upper plate and the lower plate slide against each other, and the umbrella starts to open. The sliding of the upper plate and the lower plate is controlled by the control device at the handle.

The acute angle formed by the connection of the long rib and the short rib is characterized in that the angle of the acute angle changes with the opening and closing of the umbrella, and the angle is close to zero when the umbrella is closed.

After the umbrella is closed, in order to prevent the acute angle from being zero, the two umbrella ribs tend to be parallel and appear at a static point, and the circumference of the upper wall is greater than that of the lower wall, so that the umbrella can be opened conveniently.

The invention has opened up a new development direction of the umbrella manufacturing industry. It has a simple structure and low cost, especially without springs and external force to store energy in advance, and can be opened and closed repeatedly at will, which greatly facilitates users.

Detailed ways

Embodiment 1 As shown in Figure 1, it is made of the manipulation device in umbrella pole, upper plate, lower plate, umbrella rib, drawing wire, guide wire shaft, handle and handle. Figure A in Fig. 1 is a schematic diagram of the bottom plate 4, with a horizontal plate in the middle, and the thickness of the horizontal plate corresponds to the groove E hollowed out at the upper end of the umbrella pole 1. Figure B is a schematic diagram of the guide wire shafts b, b ₁ and b ₂ , the guide wire shaft b is fixed on the upper end of the umbrella shaft 1, and the guide wire shafts b ₁ and b ₂ are respectively fixed on the inner lower end of the umbrella shaft 1, the function of the guide wire shafts is to reduce friction. The umbrella pole 1 is a hollow tube, and the two ends are fixedly connected with the handle 2 and the upper plate 3 respectively. The lower plate 4 is set on the upper end of the umbrella pole, and can slide up and down along the hollow groove E. The upper plate 3 and the lower plate 4 are connected with the long rib 6 and the short rib 5 respectively. The two ribs are connected to the joint O and form an acute angle O. There are drawing wires a ₁ and a ₂ inside the umbrella pole 1, one end of the drawing wire a ₁ is fixedly connected with the lower plate 4, and the other end is fixedly connected with one end of the operation panel 7 through the guide wire shaft b ₁ ; one end of the drawing wire a ₂ passes through the lower plate 4 and bypasses The guide wire shaft b is affixed to the lower plate 4, and the other end is affixed to the other end of the operation panel 7 through the guide wire shaft b ₂ . Figure 1 shows that the umbrella is open. When the operating panel 7 is pushed to the right, the pull wire a ₂ pulls the lower plate 4 to slide upwards and slides against the upper plate 3. At the same time, it drives the short rib 5 upward, and the long rib 6 moves downward, and the umbrella starts to close. , the angle of the acute angle O decreases at any time, and when it is close to zero, the umbrella is closed. On the contrary, operating panel 7 pushes to the left, drawing wire a ₁ pulls lower plate 4 and upper plate 3 to slide oppositely, umbrella begins to open, and the angle of acute angle O expands thereupon. Repeatedly, the umbrella can be opened and closed repeatedly in a cycle.

When the umbrella is closed, for preventing the acute angle O from being zero, the two umbrella ribs tend to be parallel and there is a static point, which is difficult to open, and the circumference of the upper wall 3 is greater than the circumference of the lower wall 4.

The operating panel 7 has openings D ₁ and D ₂ , which can slide when inserted into the handle 2 . The unlocking plate 8 has pits C ₁ and C ₂ , which are inserted into the operating plate 7 and can slide. The handle 2 has a ball 9 and a spring 10 . As shown in Figure 1, when the operating panel 7 is pushed to the right, the unlocking plate 8 is first touched, and the unlocking plate 8 is pushed, and due to the slope of the depression C2 _on the unlocking plate, the ball 9 is pressed down to unlock. The operating panel 7 can be slid to the right, so that the umbrella can be folded and closed. At the same time, the dimple _C1 is opposite to the opening D1, and the spring ₁₀ springs the ball 9 into the lock. At this time, the unlocking plate 8 protrudes from the other end of the operating plate 7, and is ready for unlocking next time. On the contrary, the slope effect of the pit _C1 is unlocked, the operating panel 7 can be slid to the left, and the umbrella is opened, the pit _C2 is opposite to the opening D2, and the ball ₉ is snapped into and locked.

The distance that the operating plate 7 slides is equal to the distance between the upper plate 3 and the lower plate 4 when the umbrella is opened. It has been proved from the practice of the samples made that the distance between the upper plate 3 and the lower plate 4 is shorter (not more than 6 cm), that is, the moving distance of the operating panel 7 is also shorter, so that the operation with one hand becomes a reality.

Embodiment 2 FIG. 2 is a schematic structural diagram of this embodiment. The difference from embodiment 1 is the control device. In addition, in order to shorten the distance used during manipulation, the original short rib 5 is designed to be a long rib, the original long rib 6 is a short rib, and the upper plate 3 and the lower plate 4 are set in the hollow groove E of the umbrella pole 1. , can slide along the groove. After one end of the drawing wire a ₁ is fixedly connected with the lower disc 4, it passes through the upper disc 3 and bypasses the wire guide shaft b to be fixedly connected with the upper disc 3, and one end of the drawing wire a ₂ passes through the lower disc 4 and is fixedly connected with the upper disc 3. _In this way, when pulling the wire a1 or the wire a2 to open and close the umbrella, the distance used during manipulation will be shortened by more than half.

The control device of the present embodiment is designed in this way. As shown in Figure 2, one end of the n-shaped plate 11 is firmly connected to the umbrella pole 1, and the other end is connected to the handle 2 through the shaft 12. The upper end of the handle 2 is fan-shaped, and the side length of the fan is equal to the length of the pull wire a ₁ required when the umbrella is opened. adapt. This fan is inserted in the middle of the n-line board 11, the handle 2 has a spring 10 and pins 9, there are pits D ₁ and D ₂ corresponding to the pins 9 on the n-line plate 11, and the other ends of the wires a ₁ and a ₂ are guided The silk shafts b ₁ and b ₂ are fixedly connected to both ends of the fan respectively.

Figure 2 is the state when the umbrella is opened. When the pin 9 is moved down to break away from the pit D ₁ , and the umbrella is tilted forward, due to the action of gravity, the umbrella naturally sags continuously and moves relative to the handle 2 with the axis 12 as the center of the circle. Due to the principle of leverage, the fan of the handle 2 gets enough force to drive the drawing wire a ₂ to pull the upper plate 3 downward, and at the same time, the drawing wire bypasses the guide wire b and pulls the lower plate 4 upward, so that the upper plate 3 and the lower plate 4 slide towards each other until the umbrella is closed , marble 9 pops into the pit D ₂ to lock. On the contrary, after unlocking, the umbrella is tilted forward, and the fan surface drives the wire drawing a ₁ to pull the lower plate 4 downward, while the upper plate 3 is upward, and the upper plate 3 and the lower plate 4 slide against each other until the umbrella is fully opened and locked. Repeatedly, the umbrella can be opened and closed repeatedly.

Embodiment 3 FIG. 3 is a schematic structural diagram of this embodiment. The difference from Embodiments 1 and 2 is that the umbrella pole is composed of a plurality of strips 17 (the present embodiment adopts two strips 17), a base 14, and an umbrella top 13. The base 14 is fixedly connected with the two strips 17, the umbrella top 13 is plugged in with the two strips 17, and the umbrella top 13 can be removed and installed as required. There is a hole in the middle of the bottom wall 4 and is fixedly connected with the appropriate positions of the two elongated bodies 17 upper ends. The upper plate 3 has two holes corresponding in size and shape to the two elongated bodies 17, and is set on the two elongated bodies 17. The cylinder at the center of the upper plate 3 passes through the corresponding hole in the middle of the lower plate 4, and the upper plate 3 Can slide up and down freely.

The control device is composed of a parallelogram combination a, an opening handle 15 and a closing handle 16. Parallelogram combination a is formed by the intersection of several long strips, and each connection point is a link. A pair of opening handles 15 are flexibly connected to the endpoints of the two extended strips below the parallelogram combination a; a pair of closing handles 16 are respectively connected to the diagonal connection points B ₁ and B ₂ of the parallelogram below. There is an axis hole A at the lower cross connection point of the parallelogram combination a and is movably connected with the base 14 through the axis hole A. The upper end of the parallelogram combination a is fixedly connected with the lower end of the cylinder at the center of the upper plate 3 .

The opening and closing of umbrella is realized like this. Hold the opening handle 15 by hand, and when you hold it firmly, the parallelogram combination a is deformed, pushing the upper plate 3 upwards and sliding against the lower plate 4, and simultaneously driving the long ribs 6 and the short ribs 5 to gradually open the umbrella. At the same time, the handle 16 is closed and gradually pushed out, as shown in FIG. 3 . Hold the closed handle 16, and when you hold it tightly, the parallelogram combination a deforms and pulls the upper plate 3 to slide towards the lower plate 4, driving the long ribs 6 and the short ribs 5, when the distance between the upper plate 3 and the lower plate 4 is close to 0 , the umbrella is closed. Push out and open handle 15 simultaneously. Repetition can realize repeated opening and closing.

The length of the deformation elongation or shortening of the parallelogram combination a is equal to the distance between the upper plate 3 and the lower plate 4 when the umbrella is opened. The length of the parallelogram combination a deformation elongation or shortening depends on the number or size of the quadrilateral.

When opening or closing, the movement distance of the opening handle 15 and the closing handle 16 is relatively small, so hands can be easily exchanged.
