Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called A-type jump umbrella, which is an automatic umbrella-opening umbrella.

[0002]

2. Description of the Related Art Conventionally, an automatic umbrella-opening umbrella called a jump umbrella has been known.

Such an automatic umbrella-opening umbrella is slidably inserted onto the center rod and is urged to slide in the upward direction via an umbrella spring. With a cistern attached to the center rod to lock it near the hand of the player, and a push button provided at the tail end of the cistern, the lower lock is locked to the locking claw of the cistern in the closed umbrella position. When the push button is pressed from, the lower roller is automatically lifted by the opening spring to open the umbrella.

In this way, the automatic opening umbrella western umbrella of the type in which only the lower potter's wheel of the closed umbrella position can be disengaged by blazing
In addition to engaging and disengaging the lower lock, such as a jump umbrella, the dew receiver automatically holds the debris holder that holds the group of ribs that are focused when the umbrella is closed and pushes the pushbutton. The automatic umbrella-opening umbrella that releases the skeleton ribs is called a type A jump umbrella.

[0005]

In the hitherto known type A jump umbrella, the dew receiving body is normally urged by the spring in the direction of releasing the ribs, that is, in the direction of retracting the dew receiving body, and the closed type. When the dew receiving member is advanced to hold the dew end of the rib group while holding the umbrella, the dew receiving member is locked to the claws of the cistern.

Therefore, when opening the umbrella from the closed state,
When the push button is pressed, first, the claw of the cistern is released from the dew receiving body to retract the dew receiving body to release the rib group, and then the locking claw of the cistern releases the lower lock to release the lower lock. To raise and to open the umbrella. On the other hand, when closing the umbrella from the open state, when the lower wheel is lowered, the lower wheel automatically locks to the locking claws of the repellent at the closed position. Therefore, when the group of ribs is focused and the dew receiving body is advanced so as to hold the dew tip, the dew receiving body is locked by the claws of the repellent.

By the way, the conventional type A jump umbrella has the following drawbacks because it has the above-mentioned structure.

When the push button is pressed while the umbrella is opened, the dew receiving member is released from the claw of the cistern first, and then the lower wheel is released from the locking claw of the cistern. However, when the configuration is such that two operations are performed before and after during a pressing stroke with a short cissing, it is inevitable that the dew receiving member is released only by slightly pressing the push button. For this reason, if the user accidentally touches the push button in a crowd of people such as on a train or on the street, the skeleton will be unfocused and open halfway. Will bother you.

When the pushbutton is pushed to retract the dew receiving member, since the dew receiving member is biased in the backward direction by the spring, as soon as the dew receiving member is released from the claws of the cistern, the dew receiving member moves backward vigorously, The housing surrounding the push button collides violently and stops. For this reason, when the dew receiver and the housing are made of synthetic resin, cracks and the like are likely to occur due to impact, and it is necessary to design the mechanical strength unnecessarily.

Since the spring is arranged on the front side (opposite to the hand side) of the dew receiver and provided on the outer circumference of the center rod, the spring is in a state of being visually recognized from the outside, and the appearance is impaired.

At the time of closing the umbrella, while the rib groups are focused, the dew receiver must be moved forward until it is locked by the claws of the cistern, so that the focus group locking of the rib groups cannot be performed with one touch.

In addition to the above-mentioned structure, the conventional A-type jump umbrella is provided with a housing located at the tail end of the cistern and surrounding the center rod, and a push button is housed in the housing, which will be described later. As described above, since the push button is configured to project from the inside of the housing to the outside, the assembly is difficult and the assembling work efficiency cannot be improved.

An object of the present invention is to eliminate various drawbacks found in such a conventional type A jump umbrella.

[0014]

According to the present invention, the first means is constructed so that it is slidably mounted on a center rod and is biased to slide in an upward direction via an opening spring. A lower wheel, a cistern that is installed in the center rod to lock the lower wheel near the center of the center rod, a housing that is located at the tail end of the center rod and surrounds the center rod, and the tail of the cistern. A push button that is provided at the end and that protrudes freely into the outer circumference of the housing, and a bowl-shaped dew receiver slidably inserted on the center rod to hold the dew point of the rib group gathered near the push button. The repelling body is elastically supported by pushing the push button in the radial direction of the center rod so as to be freely restored. A locking claw that protrudes from the side opening and locks the lower lock at the closed position is provided, and the other side of the repellent is also provided with the locking claw. Is provided with a release claw protruding from the other side opening of the center rod and a cam is formed on the release claw, and the dew receiving body is urged toward the dew point of the bundled rib group. A spring is provided, and a driven portion is provided along the cam of the release claw to retract the dew receiving member against the spring when the release claw is projected.

The present invention is configured as a second means. In addition to the first means, the dew point of the ribs forms a guide surface having a rounded tip, and the dew receiver has a bowl-shaped portion. Is formed so that the guide surface slides on the driven surface to retract the dew receiver against the spring when the rib group is focused. is there.

Further, the third aspect of the present invention is that the lower wheel is slidably inserted into the center rod and is urged to slide in the upward direction via the opening spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a main part of an automatic umbrella-opening umbrella. An upper wheel is fixed near a front end of a center rod 1 made of a pipe material (not shown), and a base end of a rib 2 is attached to the upper wheel. And a dew point 3 made of synthetic resin or the like is attached to the tip of the rib 2. A middle wheel 4 and a lower wheel 5, which are slidable in the axial front-rear direction of the middle bar 1, are externally inserted in the middle part of the middle bar 1, and both the rockers 4 and 5 interpose an opening umbrella spring 6 therebetween. It is biased in the direction of separation. A proximal end of a fulcrum (not shown) is pivotally attached to the intermediate rocker 4, and a distal end of the fulcrum has a rib 2
It is connected to the middle of the road. Further, a base end of a lamella (not shown) is pivotally attached to the lower wheel 5, and a tip of the lamella is pivotally connected to a middle part of the fulcrum. Therefore, with such a frame structure and a rocker structure, in a state where the lower rocker 5 is free, the front end of the center rod 1 is biased by the action of the opening umbrella spring 6 in the direction in which the middle rocker 4 and the lower rocker 5 are separated from each other. It rises in the direction and automatically opens the umbrella. 7 at the tail end of the center rod 1.
Is attached, and at the front position near the hand 7
Is attached to the center rod 1. The cistern 8 has a push button 9 attached to its tail end, and is elastically supported by pushing the push button 9 in the radial direction of the center rod 1 so as to be freely movable and restored. When the lower wheel 5 is moved near the hand, the lower wheel 5 is locked. These configurations are similar to those of the conventionally known automatic umbrella-opening umbrella.

The center rod 1 has a first side opening 10 and a second side opening 11 which face each other in the radial direction. Correspondingly, the repellant 8 is provided with a locking claw 8a and a button support portion 8b that can be retracted from the one side opening 10, and is provided with a release claw 8c that can be retracted and retracted from the other side opening 11. That is, when the repellant 8 is rebounded, the locking claw 8 a projects from the one side opening 10 and the release claw 8 c is positioned in the other side opening 11. However, when the crater 8 is pushed through the push button 9, the locking claw 8a is retracted from the one side opening 10, while the release claw 8c is projected from the other side opening 11. In the illustrated example, the one side opening 10 is
Although it is formed in a long slit shape that allows the locking claw 8a and the button support 8b to project and retract, the locking claw 8a and the button support 8b are formed.
The one-side opening 10 may be divided and formed so that each of them can be individually projected and retracted.

Corresponding to the locking claw 8a of the repellent 8, the sleeve 5a of the lower wheel 5 is releasably locked by the locking claw 8a in a state where the lower wheel 5 is moved to the closed umbrella position. Hole 1
2 is formed.

The housing 13 is located at the tail end of the cistern 8 and encloses the center rod 1 and surrounds the button support portion 8b. The housing 13 is integrally molded of synthetic resin and has a small-diameter sleeve 14. The small-diameter sleeve 14 is externally fitted to the center rod 1 at the front end side of the hand 7, and is fixed by a pin 15. The small-diameter sleeve 14 is surrounded by the hand 7.

The dew receiving body 16 is provided on the front end side of the housing 13, and has a bowl-shaped portion 17 for holding the dew tip 3 of the two ribs 2 to be bundled when the umbrella is closed, and a tail end from the bowl-shaped portion 17. Direction, and an extension portion 18 slidably inserted into the outer circumference of the housing 13, and a cylindrical portion 19 slidably inserted into the outer circumference of the center rod 1, which is made of synthetic resin. It is molded. Then, the dew receiving body 16 and the housing 13
A spring 20 is interposed between the two, and the dew receiving member 16 is constantly urged toward the dew point 3 of the bundled two ribs.

In the illustrated embodiment, a metal bush 21 is fitted on the inner peripheral surface of the cylindrical portion 19 of the dew receiving member 16, and the bush 21 is slidably fitted on the center rod 1. Therefore, the stopper 21a extended from the bush 21 is made to be freely engageable with the inner side surface of the housing 13, whereby the maximum forward position of the dew receiving member 16 by the spring 20 is set. In addition, the dew receiver 16 is attached to the spring 2
When pushed down against 0, the cylinder portion 19 with the bush 21 is attached.
Is moved into the housing 13, and the extension 18
By sliding the outer peripheral surface of the housing 13 on the outer periphery of the housing 13, the dew receiving member 16 moves backward.

In this structure, the dew point 3 of the rib 2 forms a guide surface 3a having a rounded tip, while the bowl-shaped portion 17 of the dew receiving member 16 recedes from the opening edge toward the outer peripheral direction. A rounded driven surface 17a is formed. Therefore, when the lower rocker 5 is locked by the locking claws 8a of the cistern 8 and the user holds the two ribs 2 in the halfway open posture with the palm or the like, the guide surface 3a is moved. The dew receiving member 16 is retracted against the spring 20 by sliding on the surface 17a. Then, when the dew tip 3 reaches the inside of the opening of the bowl-shaped portion 17, the dew receiving member 16 moves to the spring 2
It returns to the original position by 0, and holds the exposed tip 3 of the group 2 of the ribs 2 which is focused by the bowl-shaped portion 17. Therefore, the focusing and holding of the rib group by the dew receiving member 16 can be automatically performed by such a one-touch operation.

The release claw 8c of the cistern 8 is the release claw 8c.
The taper-shaped cam 22 is provided so as to incline from the tip of c toward the tail end of the cistern 8.
It is provided with a driven portion 23 for retracting the dew receiving member 16 along the cam 22 when c is projected. In the illustrated embodiment, the driven portion 23 is formed of a part of the bush 21 to prevent wear due to the sliding of the cam 22, but the driven portion 23 is driven by a part of the tubular portion 19 without providing the bush 21. The part 23 may be configured.

Therefore, in the closed state shown in FIG. 1, when the push button 9 is pushed in to push the repellant 8, the catch claw 8a of the repellant 8 separates from the catch hole 12, as shown in FIG.
Use the umbrella spring 6 to raise the lower wheel 5. At the same time, the release claw 8c of the crater 8 is projected from the other side opening while the cam 2
The driven part 23 is pushed down by 2 and the dew receiving member 16 is retracted against the spring 20, and the dew point 3 of the rib group 2 is moved to the bowl-shaped part 1.
Release from 7 and expand 2 groups of ribs. In the illustrated embodiment, when the push button 9 is pushed in, the dew receiver 16 is not retracted to the position where the dew tip 3 is released before the locking claw 8a is disengaged from the locking hole 12. Without release claw 8
Since the inclination angle of the cam 22 of c is set in this way, the dew receiving body 16 will not release the main rib 2 even if the user slightly pushes the push button 9 due to a malfunction. .

Next, an example of the structure of the push button 9 will be described. As shown in FIG. 3, the push button 9 includes a pair of legs 2.
4 and 24 and a head portion 25 provided on the upper portions of the leg portions 24 and 24, which are integrally molded of synthetic resin. A fitting portion 26 is provided between the leg portions 24, 24. In the illustrated example, the fitting portion 26 is made of a pin, but it may be integrally formed with the push button 9. On the other hand, the button support portion 8b of the repellent 8 is
A notch 27 is formed from the side edge on the tail end side, and the fitting portion 26 can be fitted in the notch 27. Housing 13 has push button 9
We have opened a button opening 28 that allows you to insert the
The button opening 28 has a large space in which the push button 9 can be idled on the tail end side (hand side) with the push button 9 inserted.

Therefore, as shown in FIG. 3 (A), the center rod 1
On the other hand, after the repellant 8, the housing 13, the dew receiving member 16 and the hand 7 are mounted, the push button 9 can be mounted on the button support portion 8b of the repellant 8 in such an assembled state. That is, if the push button 9 is inserted into the button opening 28 on the rear side of the button support portion 8b and then the push button 9 is moved forward and the fitting portion 26 is fitted into the notch 27, the push button 9 can be easily and easily carried out.
Can be attached. At this time, if the opening of the notch 27 is formed in a constricted shape, the fitting portion 26 is fitted into the notch 27 in a so-called hell shape, and thereafter, the fitting portion 26 does not come out of the notch 27, and a preferable result is obtained. Can be obtained.

From this point of view, the push button in the conventional type A jump umbrella has a push button 40 as shown in FIG. 3 (C).
Was made to project from the inside of the housing 41 to the outside. The push button 40 is provided with flanges 42, 42 that are locked inside the housing 41, and a head portion 44 that is inserted from the flange into the button opening 43 of the housing 41 and projects to the outside. Therefore, under such a structure, after the cistern 46 is attached to the center rod 45, the push button 40 is first housed in the housing 41,
The housing 41 is externally inserted into the center rod 45, the housing 41 is fixed at a predetermined position, and the push button 40 in the housing 41 is attached to the crater 46, which is extremely troublesome work.

According to the above-described embodiment of the present invention, the housing 13 is first attached to the center rod 1 and then the push button 9 is inserted from the outside of the housing 13 as compared with the conventional laborious work.
Since it can be attached to the button support portion 8b of the cistern 8, the work is extremely simple and easy.

As a result of such a configuration, FIG.
As shown in (B), the head portion 25 of the push button 9 can be formed wide, and the push button 9 that can be easily operated by the user's fingers can be configured.

[0032]

The conventional type A jump umbrella first unlocks the dew receiver during the short stroke of repelling,
Then, since it was configured to perform two operations of releasing the lock of the lower wheel before and after, the dew receiver was released and the ribs were opened halfway with a slight push of the push button, causing annoyance to neighbors. According to the present invention described in claim 1, while there is a risk of putting the hook, the operation of retracting the locking claw 8a into the center rod 1 and the release claw 8c during the pushing stroke of the crater 8. Since the operation of projecting from the rod 1 is performed at the same time, there is no possibility that the dew receiving member 16 will retreat and the rib 2 will be released by a slight push of the push button 9, which is safe.

Further, in the conventional type A jump umbrella,
As soon as you push the pushbutton to release the dew receiver from the claws of the cistern,
In contrast to the dew receiver that was vigorously retracted by the spring and was violently collided with the housing, according to the present invention, the push claw 9c pushes the release claw 8c and the cam 22 and the cam 22. Since the configuration is such that the dew receiving member 16 is retracted against the spring 20 via the driven portion 23, no impact is generated when the dew receiving member 16 moves back and forth, and the dew receiving member 16 and the housing 13 may be damaged. It is durable and can withstand long-term use.

Further, in contrast to the conventional A-type jump umbrella, in which the spring of the dew receiving body is obliged to be mounted at a position visible from the outside, the present invention according to claim 1 For example, since the spring 20 can be interposed between the dew receiving member 16 and the housing 13 and the spring 20 cannot be visually recognized from the outside, it is possible to provide a western umbrella having an excellent appearance.

By the way, in the conventional A-type jump umbrella, when the rib groups are focused and held when the umbrella is closed, one side of the jump group can focus the rib groups, while the other hand locks the dew receiver to the claws of the cistern. According to the present invention as set forth in claim 2, it is necessary to focus the two rib groups together with only one hand, whereas the two touch operation of moving the guide bone to the front is required. The surface 3a slides on the driven surface 17a of the dew receiving member 16 to retract the dew receiving member 16 against the spring 20, and then the dew receiving member 16 is moved to the spring 2a.
By returning to the original position by 0, it is possible to automatically perform a series of operations of holding the dew point 3 and to perform a one-touch operation for concentrating the ribs.

Further, in the structure of the conventional type A jump umbrella,
While the push button is housed in the housing, the housing is attached to the center rod, and the push button is made to protrude from the inside of the housing to the outside, so that the assembly is difficult and the assembly work efficiency cannot be improved. According to the present invention as set forth in claim 3, the housing 13 is first attached to the center rod 1, and after completing such an assembly, the push button 9 is attached to the button support portion 8b of the cistern 8 from the outside of the housing 13. Since it can be attached, work is extremely easy and easy, and work efficiency can be greatly improved. Moreover, as a result of such a configuration, the degree of freedom in designing the shape of the push button 9 is increased, and, for example, by forming the head to be wide, it is possible to configure a push button that can be easily operated by the user's fingers.
