Definitions

• the present invention relates to an umbrella, and more particularly to an automatic opening and closing umbrella safety structure.
• the automatic opening and closing umbrella can complete the automatic opening and automatic umbrella lifting operation by simply pressing the same button repeatedly, which saves the trouble of opening or closing the umbrella with both hands, and is very convenient to use. Therefore, once it was published, it was widely loved by the public.
• the Chinese utility model patent of 76208Y discloses a 'control device for automatically opening and closing the umbrella'.
• the action principle of the automatic opening and closing umbrella is: When the umbrella is to be opened, the button 60 ' is pressed down, so that the umbrella bar 50' loses control of the control device, and the open umbrella spring 51' inside the umbrella bar 50' releases energy. , the umbrella stick 50' is stretched upward to make the umbrella open; and when the umbrella is to be put up, press the button 60' down again, so that the buckle 523 in the umbrella rod 50' also loses control of the control device.
• the buckle 523 is released, and under the elastic force of the umbrella spring (not shown) on the umbrella frame, the umbrella surface is in an umbrella state, and the buckle 523 is pulled back into the umbrella by the rope 522 ' The top of the stick 50'; this ⁇ is still in the state of not fully closing the umbrella.
• the umbrella rod 50' and the buckle 523 are again controlled by the control device in the grip 11CT, so that the umbrella is completely folded.
• the existing automatic opening and closing umbrella is easy to operate, but it has potential safety hazards.
• the specific reasons are as follows: Since the umbrella rod is installed with an open umbrella spring, the open umbrella spring is responsible for automatically opening the umbrella when the umbrella is hit, so the elastic force is large. When the umbrella surface has been folded, it is necessary to press the umbrella surface to the grip position. The elastic force of the open spring must be overcome, and the umbrella must be pressed in place to completely close the umbrella.
• the technical problem to be solved by the present invention is to provide an automatic opening and closing umbrella safety structure, which can prevent the phenomenon that the automatic opening and closing of the umbrella is in the umbrella and the rod in the umbrella is unexpectedly opened.
• An automatic opening and closing umbrella safety structure which is disposed inside the main body of the umbrella grip, including a rotating shaft and a ratchet
• the spring shaft is pivoted to the bottom of the main body, the ratchet is fixed at one end, the spring is fixed at the other end, and a ratchet is arranged on the ratchet, and the outer end of the spring is fixed on the main body; One end is pivotally connected to the main body, and the free end is opposite to the ratchet of the ratchet.
• the inner side of the positioning block is provided with a convex block, and the convex piece protrudes from the one side hole in the main body side wall into the shaft hole of the main body, and is inside the rod in the umbrella
• the position of the buckle is set to be opposite to the position of the buckle; the one end of the pull rope is fixed on the rotating shaft, and the other end is fixed on the upper nest of the top end of the umbrella.
• a positioning spring piece is arranged between the positioning block and the inner wall of the handle to reset the free end of the positioning block against the ratchet ratchet.
• a through hole is opened in the buckle, and the drawstring passes through the through hole.
• the present invention since the present invention has a safety structure inside the umbrella grip, when the umbrella is closed and the rod in the umbrella is shortened, the lower end of the rope is under the elastic force of the spring. Constantly wound around the shaft, if the force on the rod in the umbrella disappears, the rope will drive the shaft to reverse, and then, the free end of the positioning block will reach the ratchet of the ratchet to prevent the shaft from reversing, thus Pull the rope to the nest and prevent the rod from popping outward. That is to say, the invention utilizes the unidirectionality of the ratchet.
• Figure 1 is a schematic view of the structure of the existing automatic opening and closing umbrella handle
• Figure 2 is an exploded perspective view of the present invention
• Figure 3 is a sectional view of the combination of the present invention (the state of the umbrella process);
• Figure 4 is a sectional view of the combination of the present invention (the umbrella is fully stowed);
• Figure 5 is a sectional view of the combination of the present invention (an umbrella open state).
• the safety structure of the present invention is disposed inside the main body 2 of the umbrella grip 11, and mainly comprises a rotating shaft 3, a ratchet 4, a spring 5, a positioning block 6, a reset elastic piece 7 and a pull cord 8. among them:
• the handle 11 and the main body 2 therein are provided with control means. Since the control means is not the focus of the present case, it is not shown in the drawing.
• the main body 2 has a shaft hole 21 for mounting the umbrella rod 12, and the umbrella rod 12 is provided with a buckle 9.
• the shaft 3 is pivoted to the bottom of the main body 2, and a ratchet 4 is fixed at one end thereof, and a spring 5 is fixed at one end.
• the outer end of 5 is fixed to the main body 2.
• the ratchet 4 is provided with a plurality of ratchet teeth 41, which function to make the rotating shaft 3 have a tendency to rotate.
• the positioning block 6 is pivotally connected to the main body 2, and the free end 61 different from the pivot end is opposite to the ratchet 41 of the ratchet 4.
• the inner side of the positioning block 6 is provided with a projection 62 which projects from the side hole 22 in the side wall of the main body 2 into the shaft hole 21 of the main body 2 and is opposite to the position where the buckle 9 is retracted.
• the reset elastic piece 7 is disposed between the positioning block 6 and the inner wall of the grip 11.
• the drawstring 8 is fixed to the rotating shaft 3, and the other end is fixed to the upper nest (not shown) of the top end of the umbrella.
• a through hole 91 is opened in the buckle 9 to allow the drawstring 8 to pass through the through hole 91.
• the buckle 9 is pulled over the umbrella bar 12.
• the umbrella rod 12 is further pressed to shorten it so that the umbrella is completely retracted, as shown in FIG. 3, the lower end of the cord 8 is elastic in the spring 5 during the shortening process.
• the force is continuously wound around the rotating shaft 3, and once the force pressed on the rod 12 in the umbrella disappears, the pulling rope 8 will drive the rotating shaft 3 to reverse, and then, the free end 61 of the positioning block 6 is in the elastic force of the reset elastic piece 7.
• the rotation shaft 3 is prevented from being reversed, so that the pull cord 8 is pulled over the upper nest of the umbrella, and the rod 12 is prevented from being bounced by the action of the open spring (not shown). Therefore, it is possible to prevent an accident in which the rod in the umbrella is wounded by accidental bouncing.
• the buckle 9 is in a state of being retracted to the inside of the grip 11, and is controlled by the control device ( Not the focus of this case, not shown in the figure).
• the buckle 9 is opposite to the projection 62 of the positioning block 6 and abuts against the projection 62, pushing the positioning block 6 outwardly, so that the free end 61 of the positioning block 6 is disengaged from the ratchet 41 of the ratchet 4.
• the drawstring 8 is wound around the rotating shaft 3. Due to this, the positioning block 6 is not in contact with the ratchet teeth 41 of the ratchet 4 by the buckle 9 so that when the umbrella is opened, the ratchet 4 does not restrict the elongation of the cable 8 and the umbrella can be smoothly opened, as shown in FIG. Show.
• the invention utilizes the structure in the automatic opening and closing umbrella, that is, the buckle 9 to release the rotation restriction of the positioning block 6 on the ratchet 4, so as to prevent the pulling rope 8 from being elongated due to the restriction of the positioning device 6 by the ratchet wheel 4, and further The phenomenon that the umbrella cannot be opened.
• the present invention can also remove the rotation limit of the positioning block to the ratchet by other control structures.
