Description

Full-automatic umbrella

The utility model relates to a kind of en-toutcas of folding automatically.

The en-toutcas of the folding of having designed at present automatically is a lot, and what have patents." automatic opening-closing umbrella " (notification number 2160238) comprises umbrella cover, holds handle, the parachute-opening handle, closes umbrella control bolt and four connecting rod folding umbrella mechanisms.Parachute-opening is driven the parachute-opening wire drawing, is closed umbrella control bolt, wire drawing and quadric chain and finish by the parachute-opening handle, closes umbrella and is finished automatically by quadric chain by the gravity of umbrella cover and umbrella frame." receiving certainly from opening en-toutcas " (notification number 2123910) comprises umbrella cover, umbrella frame, extension spring, umbrella bar, umbrella handle.The folder horse displacement elongated slot of band displacement pivot pin is arranged between extension spring and push-and-pull bar, and the interior bar bottom toothing bar of umbrella bar is with the flat gears engaged that is contained on the umbrella handle.Pull umbrella opener, because the displacement pivot pin displacement in the folder horse displacement elongated slot, the stress of change extension spring, en-toutcas folding automatically.

The purpose of this utility model aims to provide a kind of en-toutcas with new automatic open-and-close mechanism.

The purpose of this utility model realizes in the following manner, full automatic umbrella, comprise umbrella cover, handle 13, upper and lower umbrella bar 6,25, by last wheel 7, down wheel 3, umbrella frame 10, on bone 11, sector gear quadric chain and the open-and-close mechanism that bone 9 and umbrella frame chain 12 constitute that open an umbrella that open an umbrella.Following wheel will be gone up lower umbrella rod and be connected as a single entity.Gear stick bottom sleeve spring 2 in the following wheel.The open an umbrella gears engaged of bone 9 head ends of gear stick and sector gear.Steel wire drawing 8 one ends are fixed on the gear stick, and an end is fixed on the sliding card 24.Dress switch assembly 23 on the lower umbrella rod of spring compressive state downslide Ka Suochuweizhichu.Following steel wire drawing 22 upper ends are fixed on sliding card 24 lower ends, and the pulley 20,19 that is positioned at boosting-rod 14 is walked around in the lower end, passes diaphragm plate 18, and the termination is a plush copper 17.

Accompanying drawing is the utility model structural representation.

With reference to accompanying drawing, umbrella frame when dotted line is depicted as umbrella and closes up among the figure, last support companion bone, the gear bone state of living in that opens an umbrella.Connect gear stick 5 in the steel wire drawing 26, connect sliding card 24 down.Switch assembly 23 comprises handle, lever, spring.Lever upper end and handle end in contact, the lower end is stretched in the umbrella bar groove, shock mount between umbrella bar and lever.Following steel wire drawing 22 upper ends are fixed on sliding card 24 lower ends, and the pulley 20,19 that is positioned at boosting-rod 14 is walked around in the lower end, passes diaphragm plate 18, and the termination is a plush copper 17, and diaphragm plate can not passed in the restriction termination.The gears engaged of gear stick and sector gear strut bone 9 head ends.The wheel that has been threaded down below the following wheel covers 1, so that convenient the installation changed gear stick 5 and spring 2.There is buffer substrate tablet 4 following wheel top, the impulsive force in the time of can alleviating spring 2 returns when closing one's umbrella.Lower umbrella rod 25 lower ends and boosting-rod one end closely cooperate, and form a meniscus shaped jointly.Lower umbrella rod lower end elbow stretches out a hook shape reinforcement 15, colludes wall and cooperates with the boosting-rod wall, and the termination is connected with boosting-rod with elastic hinge 16.Lower umbrella rod bottom, boosting-rod overcoat handle 13 have a leather sheath 21 on the handle.When hand passes in leather sheath, when catching boosting-rod, because leather sheath is lived gloves, umbrella can not toppled over firmly the time.

Umbrella frame 10 terminations are Y-shaped, make the umbrella cover end face that one turn-over be arranged, and have two osculums of 180 ° of symmetries at the umbrella cover eaves, avoided rainwater to stay along all umbrella frames and drenched clothing, also avoid umbrella top ponding, increase the weight of umbrella.

During parachute-opening, hand passes leather sheath 21 and grabs boosting-rod 14, following steel wire drawing 22 is to moving down, and by sliding card 24,5 downslides of steel wire drawing 8 driven gears rod, gear drive by gear stick and sector gear strut bone ends again, sector gear strut 9 downward pressing springs 2, again by on the bone 11 that opens an umbrella umbrella frame 10 is upwards pushed away, umbrella cover is opened.When spring 2 compressed fully, sliding card slided into the switch assembly place, is blocked by the lever end of switch assembly, and umbrella cover is in all the time and struts the position.

When thumb compressed switch the handle of assembly, the spring between handle and lever was compressed, and connecting-rod head outwards moves back, sliding card is thrown off, and spring 2 returns upwards push away gear stick 5, it is downward to drive the open an umbrella hinged end of bone of sector gear, again by on the bone 11 that opens an umbrella umbrella frame 10 is pulled down the umbrella cover closure.

Umbrella frame 10 cross sections are T shape, have increased the effective area of umbrella, have increased the intensity of umbrella frame, and to prevent becoming curved, distortion makes umbrella cover smooth, good looking appearance.

The utility model compact conformation, succinctly attractive in appearance, dependable performance, the intensity height, the effective area of umbrella is big, and the umbrella eaves does not drip all around, does not drench clothing.
