CN2063355U - Improved construction of umbrella frame - Google Patents

Abstract

The utility model discloses an improved structure for an umbrella frame, which causes that the umbrella can be simply opened, quickly folded and does not need a catapult to clamp, and the improved structure for an umbrella frame causes a middle bar structure to be simple, and is an umbrella device which is convenient for manufacturing. The improved structure for an umbrella frame comprises the middle bar, and an upper jacket tube is fixedly collocated at the upper end of the middle bar. An umbrella handle is matched with the lower end of the middle bar, and the annular outer margin of the upper jacket tube is hinged with a plurality of main brackets which extend outward. A slide jacket tube is sheathed on the middle bar, and can slide upward and downward, and the annular outer margin of the upper portion of the slide jacket tube is hinged with the inner ends of supporting frames which are relative to the main brackets. The outer ends of the supporting frames are hinged with the inner end position of a connecting body and the ends of the main brackets, and the outer end of the connecting body is provided with a pin. The lower side of each main bracket and the lower side of each supporting frame are provided with tension springs, one end of each tension spring is hitched on the annular outer margin of the middle portion of the slide jacket tube, and the other end of each tension spring is hitched on the pin. The improved structure for an umbrella frame can smoothly open and close the umbrella by the up-down movement of the movable jacket tube.

Description

Improved construction of umbrella frame

The utility model relates to a kind of structure-improved of umbrella frame frame, be meant especially a kind of can simple and easy parachute-opening, close one's umbrella fast and need not the catapult blocking, in making bar construction simple, be convenient to make, reaching easy-to-use, and economical and practical parachute kit.

The structure-improved of umbrella frame frame described in the utility model mainly is the structure with integrated main rod and sliding sleeve, obtains to open the simplicity that closes one's umbrella, and easy to manufacture, cost reduces.

Known most parachute kit in order to make the umbrella frame frame be fixed in the state that struts when the parachute-opening, normally is provided with catapult in middle rod, make the block card of catapult protrude in outside the rod, with the blocking moving casing, make that the umbrella frame frame is unlikely to be fallen.This device must be installed catapult in middle rod, except installing inconvenience, more increased manufacturing cost, and use is very not convenient.Automatic umbrella known today again though the catapult device needn't be set, when closing one's umbrella, must add fastening convex side at the umbrella handle place, so that parachute kit is maintained at umbrella closing state.This device causes the various shortcoming of aforementioned catapult device equally, and at umbrella closing state, and spring continues to stretch, and also makes spring tired and damage easily, so also do not conform to practicality.

The purpose of this utility model will provide a kind of novel parachute kit exactly, overcomes all shortcomings of above-mentioned known parachute kit, to reach simple and easy parachute-opening, closes one's umbrella fast and need not the catapult blocking.

Below in conjunction with accompanying drawing, describe structure of the present utility model in detail.

Fig. 1 is a part three-dimensional exploded view of the present utility model;

Fig. 2 is a planar gesture schematic diagram of the present utility model;

Fig. 3 is the utility model deployed condition figure;

Fig. 4 is the utility model umbrella closing state figure.

As shown in Figure 1, the column that middle rod (1) is formed in one, sleeve pipe (11) on the fixed configurations in the top, the lower end is equipped with umbrella handle (12); Sliding sleeve (2) then is sheathed on the middle rod (1), can slide up and down arbitrarily; The outward extending main fulcra (13) that the outer circular edge place of last sleeve pipe (11) and many cross sections are the U type are hinged; The upper, annular outer rim of sliding sleeve (2) is hinged with the inner with respect to the support bone (21) of main fulcra (13); One connector (3) places the U-shaped face inboard of main fulcra (13) near the end, the inner (31) and outer end (32) in this connector (3) are located, each wears riveted joint with a pin with connector (3) and main fulcra (13), and the outer end of aforementioned each support bone (21) also is hinged by pin and the connector (3) that connector (3) inner (31) is located; Below at each main fulcra (13) and support bone (21) is provided with tension spring (4), and the one end hook is hung on the outer circular edge place at sliding sleeve (2) middle part, and the other end then is hooked on the pin of the outer end (32) of aforementioned connector (3) locating.

As shown in Figure 2, main fulcra of the present utility model (13) are made by having better flexible material, therefore when sliding sleeve (2) by on when pushing umbrella open, main fulcra (13) will be rendered as circular-arc, and when support bone (21) is vertical with middle rod (1), suffered stay bolt power maximum, but since stressed perpendicular to middle rod (1), be static in theory; When the user passes sliding sleeve (2) a little up or down, restoring force makes sliding sleeve (2) upwards to the parachute-opening fixed position (promptly as shown in Figure 3) by this, or down to umbrella closing state (promptly as shown in Figure 4).The purpose of design of tension spring (4) mainly is to provide a pulling force, and promptly when closing one's umbrella, this tension spring (4) is a relaxed state; After parachute-opening, spring is stretched, and produces restoring force, so can reach purpose laborsaving and that be convenient to close one's umbrella when closing one's umbrella.

During enforcement, middle rod (1) can utilize the integrally manufactured moulding of material of acrylic resin and so on, and is rapidly convenient, with low cost.Last sleeve pipe (11) and the also available same material of umbrella handle (12) are made and with high-frequency welding and middle rod (1) secure bond, or make and connect with wood materials and all can with screw, the whole manufacturing and assembling very saves time, economy, the inconvenience that the installing catapult of having avoided commonly using is brought.When closing one's umbrella, each member all is in relaxation state, when not using for a long time, also can not cause damage.

In sum, the utility model the practicality of the initiative or single unit system of structure with and effect all be significant.

Claims (1)

1, a kind of structure-improved of umbrella frame frame is characterized in that, comprises in one rod, the column that is formed in one, and sleeve pipe on the fixed configurations in the top, the lower end is equipped with umbrella handle, and the outer circular edge place of last sleeve pipe and many outward extending main fulcra are hinged; Comprise that also a sliding sleeve is sheathed on the middle rod, can slide up and down arbitrarily, the upper, annular outer rim of sliding sleeve is hinged with the inner with respect to the support bone of main fulcra, and the outer end of each support bone is articulated in the place, the inner of a connector, be incorporated into the end of main fulcra again, the outer end of connector is provided with a pin; Below each main fulcra and support bone, be provided with tension spring, an end hook of spring is hung on the outer circular edge place at the middle part of sliding sleeve, and the other end then is hooked on the aforementioned pin; By moving up and down of aforementioned moving casing, get final product smooth parachute-opening and close one's umbrella.
