Abstract

The invention relates to an umbrella with automatic opening and closing, of the type with coupling. This is more particularly the case for a manoeuvre performed with just one hand. An umbrella with a single articulation or with multiple articulations may be opened or closed automatically. At the same time, the rod (1) of the umbrella may be deployed or retracted in order to give a simplified and entirely automatic manoeuvre.

Description

The present invention relates to an umbrella with an opening and

  automatic closing of the coupling type.

  In general, there are four types of conventionally used automatic opening and closing umbrellas that can be described as follows: 1 A single hinged umbrella that can be opened automatically but can not be closed automatically. 2 An umbrella with multiple joints that can be opened automatically but can not be closed automatically. 3 A single hinged umbrella that can be opened and closed automatically But its structure is not

  applicable to a multi-jointed umbrella.

  4 An umbrella with multiple joints that can be opened and closed automatically But whose stem the

  umbrella can not be retracted automatically.

  Therefore, the structure of a classic umbrella is that of a semi-automatic umbrella, it is not that of a

  fully automatic umbrella.

  There is a pin hole at the upper shaft of the umbrella (1) and a pin passes through it to connect the upper sleeve (11) and the upper shaft of the umbrella (1) There is an umbrella whale groove ( 111) at the top of the upper bushing (11) which is connected with the umbrella whale assemblies (3) There is a stop ring (112) at the base of the upper bushing (11) which is separated from the upper coupling (51) and central coupling (52) There are two short grooves at the top of the upper shaft of the umbrella (1) which are used by the first and second blade blocks (441, 442) to block the Coupling assembly (5) There is a long axial groove used to axially slide the umbrella retraction block (712) There is a V-shaped groove (see Figure 6) at the base of the upper umbrella shaft (1) which is used to lock the stopping blade (22) at the top of the lower stalk umbrella (2) to block the rod (1) There is a short transverse groove in the vertical of the V-type groove at the base of the umbrella top rod (1) which is used for fastening the pin (511) on the upper coupling (51) and the fifth blade block (48) to open the umbrella, so that the coupling assembly (5) can lock the upper shaft of the umbrella

  (1) without being separated from the umbrella upper shaft (1).

  The lower shaft of the umbrella (2) is attached to the umbrella shaft (21) by a pin (211). The pin is not above the umbrella shaft groove (212) which can secure the lower shaft of the umbrella (21). umbrella (2) and must

  not interfere with the movement of the umbrella handle spring (62).

  There is an umbrella shaft groove (21) which serves for the movement of the control knob (41) and the lower oblique sliding plate (46). There are V-type grooves (23) on both sides of the umbrella. the lower shaft of the umbrella (2) which moves parallel to the V-type groove (13) on the upper shaft of the umbrella (1) without rotation. There are three short transverse grooves vertically of the V-shaped groove (23) on the lower shaft of the umbrella (2) which serve to eject and retract the third blade block (471), the fourth blade block (472) and the

fifth blade block (48).

  The Folding Umbrella Whale Assembly (3) is drawn in connection with the multi-joint umbrella shaft A two-joint umbrella is used as an example There are four connecting rods in the umbrella whale assembly that are moving in parallel to complete the opening and closing of the umbrella One end of the first main whale (31) is connected with the umbrella whale groove (111) on the upper sleeve, the other end is connected to the middle position of four main whales (34) One end of the second main whale (32) is connected to a third position on the first main whale (31) near the fourth main whale (34), the other end is connected with one end of the third main whale (33) The distance between the point of attachment of the first main whale (31) to the fourth main whale (34) and the point d e fixation of the first main whale (31) to the second main whale (32) is taken as the distance between the point of connection on the third main whale (33) and the point of connection on the fourth main whale (34) Each point Fixes a rotation point without movement This forms a parallelogram that can move the four rods One end of the four main whales (34) is connected to the umbrella whale groove on the central coupling (52) When mating central (52) moves, it can push folding umbrella whale assembly (3) to complete

  the opening and closing of the umbrella.

  The control assembly (41 consists of: a control button (41) on the handle of the umbrella (21) which moves along a groove and is connected to the lower oblique sliding plate (46) by a rivet (411), thus the movement of the lower oblique sliding plate (46) can be controlled. With reference to FIG. 7, the movements of the third blade block (471), fourth blade block (472) and fifth blade block (48) are controlled by the lower oblique sliding plate (46) The third blade block (471) is made of spring steel sheet It carries a C-shaped ring (4722) at the end This C-type spring is attached to the base of the umbrella shaft (2) The other end of the blade block is a flat spring with an oblique lamella (4723) to come into contact with the oblique surface

  (461) at the base of the lower oblique sliding plate.

  The side of the oblique lamella (4723) forms a blade block

  triangular to lock the coupling assembly (5).

  The coupling may be released when the blade block blade (4721) is moved inside the umbrella shaft by movement of the base of the lower oblique sliding plate (46). There is a groove (464) in the center the base of the lower oblique sliding plate (46) which can not interfere with the movement of the blade unit (4721) The base of the lower oblique sliding plate (46) is held by a spring on the wall of the umbrella shaft for preventing it from falling or turning The first blade block (441), the second blade block (442), the third blade block (471) and the fifth blade block (48) can move in the same mechanism. A steel wire hard (45) is used to connect the upper oblique sliding plate (43) to the base of the lower oblique sliding plate (46) When the umbrella stem is deployed, the upper and lower oblique sliding plates (43, 46) can be move to the h An end of the upper oblique sliding plate (43) is connected with the deployment spring (42) and one end of the spring (42) is fixed on the rivet (12) When the upper oblique sliding plate (43) ) is deployed by the button control (41), the deployment spring (42) is also deployed When the control button (41) is released or the umbrella shaft is retracted, the deployment spring (42) pushes the plate sliding upper oblique (43) back to its original place. The coupling assembly (5) consists of: an upper coupling (51), a central coupling (52) and a lower coupling (53) The structure of the upper and lower couplings (51) (53) is the same But the upper coupling (51) has two sets of blade block (511), one spring (512) and one screw in one hole (513) One side of the blade block (511) is vertical and the other side is a ramp, so can be used to lock the upper shaft of the umbrella (1) (see figure 11) to prevent disengagement of the upper shaft of the umbrella (1) There are umbrella whale grooves on both sides of the upper and lower couplings ( 51, 53) which are used to equilibrate with the central coupling (52) and the umbrella spring (64, 74) is connected to the fourth umbrella whale (34) The other end of the fourth umbrella whale (34) is connected to the central coupling (52) There is aa ussi a hole (521) on the upper, central and lower couplings (51) (52) (53) and the umbrella retraction block (712) and the spring block (61) can pass through it There are holes on the upper, middle and lower couplings (51) (52) (53) used to deploy and retract the springs (63) (73), and these two springs (63) (73) are held by the inner wall of the central coupling (52) There are keyways (533) located in the holes in the ends of the upper and lower couplings (51) (53) There are three holes in the other end for locating the coupling pins (531) and the springs (532) Once the coupling pin (531), the spring (532) and the pin (533) are in place, the inclined plane (531) can pass through the key (533) to the groove (531) and reach the angle part (5312) The inclined plane (5332) on the key (533) can control the movement ent of the annular part (5312) on the coupling pin (531) When the key (533) is pushed, the inclined plane (5332) on the key (533) will push down the annular part (5312) on the coupling pin (531), then penetrate the upper and lower couplings (51) (53), and release the central coupling (52) When the central coupling (52) is inserted in the upper coupling (51) or in the lower coupling (53), they are connected by the coupling pins

(531) and the springs (532).

  The umbrella opening spring assembly (6) and the umbrella closing spring assembly (7) are comprised of: an umbrella opening spring (63) and an

  closing spring of the umbrella (73) on the coupling (5).

  When the upper and central couplings (51) (52) are connected, the closing spring of the umbrella (73) is compressed and the opening spring of the umbrella (63) is deployed Otherwise, when the central and lower couplings (52) (53) are connected, the opening spring of the umbrella (63) is compressed and the closing spring of the umbrella (73) is deployed There is a handle spring of the umbrella (62) in the handle groove umbrella (212) in the handle of the umbrella It is compressed by the closing spring of the

  umbrella e 73) in the conditions of closure of the umbrella.

  Its elastic force is less than that of the closing spring of the umbrella When the umbrella is opening, the elastic force is accumulated with respect to the opening spring of the umbrella (63> The upper stem of the umbrella (1 ) is pushed to open the umbrella by the deployment spring (713) The umbrella closing deployment spring (34) as well as the umbrella opening deployment spring (641) on the lower coupling (53) and the fourth main whale (34) is open or closed during the operation to connect the

  upper, central and lower couplings.

  The structure of an automatic umbrella according to the invention is described above, now we will describe the operating conditions as follows: Figure 1 shows an umbrella with two joints in the folded position At this moment, the coupling assembly (5) is located at the top of the umbrella shaft and the central coupling (52) is locked by the three blade blocks (471). The key (533) on the lower coupling (53) is pushed to retract the pin of the umbrella. Coupling (531) The coupling (52) is released and ready to open the umbrella As the central coupling (52) is blocked by the three blade blocks (471), the elastic force is reduced and the umbrella does not open Now, the compressed spring (73) is deployed, the closing retraction springs (713) and (741) are not deployed; but the opening retraction spring (641) is deployed; the retraction spring of the handle (62) is compressed in an elastic block (61) to engage the central coupling (52) and the pin (511) of the upper coupling blocks the short groove of the upper shaft of the umbrella, and the umbrella (641) is closed Thus, the upper rods

  and lower umbrella (1) (2) are retracted.

  The umbrella whale game (3) is folded, the control knob is held in the starting position by force

elastic spring.

  Figure 2 shows an umbrella with two joints in open condition When the hand pushes the control button down (41), the lower oblique sliding plate (46) is pushed The third blade block (471) and the fifth block blade (48) is retracted, central coupling (52) is released The umbrella opening spring (63) is released to move the central coupling (52) to move the equilibrium point between the spring (63) and the closing spring of the umbrella (73) While the spring block (61) of the opening spring of the umbrella (62) continues to push the central coupling (52) upwards to connect it with the upper coupling ( 51) After the upper and central couplings (51) (52) are connected, the fourth blade unit (472) is retracted, and the coupling assembly (5) is released. The opening springs of the umbrella (62> (63 ) begin to unfold and the spring deploys (641) begins to retract The deployment springs (741) (713) open the umbrella quickly And when the coupling assembly (5) is moved upward, the upper coupling (51) passes through the it closes the umbrella (712) it is held by the central coupling, and continues to move upward to the first blade block (441) It is retracted by the central coupling (52) and pushed back to block the central coupling (52) The second blade block (442) is also retracted by the upper coupling (53) and pushed back to lock the central coupling (53) Now the upper coupling: 51) hits the stop ring (112) in the upper bushing (11) to insert the key (533) in the upper coupling (51), and the coupling pin (531) is pushed back Then the upper and central couplings (51) (52) are separated, while the central coupling (52) is blocked by the first Blade block (441), so the umbrella can not be closed The top umbrella shaft (1) moves upwards to the V-shaped groove (13) and is blocked by the blade ( 22) on the lower shaft of the umbrella (23 (see Figure 6) The fifth blade block (48) is pushed back to hold the umbrella top rod (1) Thus the umbrella is fully open

(see Figure 3).

  FIG. 4 shows the steps of closing the umbrella which are the reverse of the opening steps of the umbrella. When the hand presses the control button (41), the lower oblique sliding plate (46), the steel wire (45) ) and the upper oblique sliding plate (43) are pushed to retract the first blade unit (441) The umbrella opening spring (73), the deployment spring (713) and the umbrella retraction block (712) force the opening spring of the umbrella (63) to retract After the central and lower couplings are connected, the

  second blade unit (442) releases the coupling assembly (5).

  Then, the umbrella is closed quickly as shown in Figure 5 When the coupling assembly (5) presses the umbrella opening spring (62), the central coupling (52) holds the spring block (61) at the bottom The upper coupling 151) pushes the upper shaft of the umbrella (1) to release the closing spring of the umbrella (713) The upper shaft of the umbrella will be pushed down to reach the handle of the umbrella (2) The central coupling ( 53) is blocked by the third blade unit (471). The upper coupling (51) is blocked by the fourth blade unit (472) and the upper shaft of the umbrella is blocked by

  the fifth blade block (48) as shown in FIG.

  The structure and operation of a single hinged umbrella are almost the same as that of a multi-jointed umbrella The difference is that the umbrella stem is a single rod Thus, folding umbrella whale assembly is brought back to a first main whale (311) and a second main whale (321) One end of the first main whale is connected with the second main whale to form a support point The umbrella opening spring (62) in the umbrella handle ( 21) is shorter There is another recessed groove used for moving the spring block (611) in the axial direction The closing spring of the umbrella (713) is replaced by a deployment spring (7131) The retraction block umbrella (712) is replaced in the reverse direction to counter the spring The fifth blade block (48 J of the command set is removed The first, second, third, fourth b blade locs (441) (442) (471) (472) and the upper and lower oblique sliding plates (43) (46) can be used in a single hinged umbrella If the previous spring is used, the oblique sliding plates are upper and lower lower (43) (461 must be replaced by a single blade control blade (49) The vertical blade (491) of the control blade is used to control the oblique blade (4724), the leaf spring (443) and (444) (see Fig. 13), thus the leaf spring can be retracted or retracted. There is another vertical leaf (492) which moves along the umbrella shaft groove to restrict the direction of movement. of the single-hinged umbrella is the same as that of the multi-jointed umbrella Figure 8 and Figure 1 show the umbrella in closed condition Figure 9 and Figure 2 show the umbrella in open condition deploys FIG. 10 and FIG. 3 show the umbrella in the open position. FIG. 11 and FIG. 4 show the umbrella in the closed position. Thus, the operating method and the principle are the same. Also, the coupling assembly (5) can be used for a single hinged umbrella and for a multi-jointed umbrella from the point of view of retraction and deployment of the upper umbrella shaft (1), while the single hinged umbrella

  does not have this element to make it simpler.

  As a result, the major objective of the invention is to eliminate the disadvantages of the classic umbrella It provides a fully automatic umbrella that can be opened and closed automatically And the umbrella whales of a multi-jointed umbrella can be deployed and retracted automatically , this umbrella with multiple joints is much more practical and pleasant

use.

  The other object of the invention is to provide a general structure that is applicable for both single hinge and multi-joint umbrellas.

  their structure is unified and generalized.

  Another object of the invention is to provide an umbrella that is operated by one hand. A single control button is used to avoid errors in

  manipulation that causes mechanical breakage.

  The invention has said structure above which can be implemented by a single button to open and close the umbrella On the other hand, the structure is simple and it is easy to manufacture, so it is an invention

truly unique and practical.

  The present invention is not limited to the embodiments which have just been described; On the contrary, it is susceptible of modifications and variants that

will appear to those skilled in the art.
