DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automatic umbrella according to the present invention will be described with reference to FIGS. 1 to 20.

(First Embodiment) First, an automatic opening / closing umbrella according to a first embodiment shown in FIGS. 1 to 12 will be described. First, the configuration of the part that performs the opening operation will be described. A mandrel 2 is axially slidably fitted around the hollow support 1, and a stopper 3 integral with the receiving bone wheel 14 and the supporting bone wheel 16 is axially slidably fitted on the mandrel 2. I have.

A rib 17 is pivotally attached to the ribs 19 at the upper end of the hollow column 1, and one end of a receiving bone 13 is pivotally connected to an intermediate portion of the ribs 17, respectively.
The other end of 3 is pivotally connected to a single receiving wheel 14 that slides around the outer periphery of the upper mandrel 8.

Further, one end of a supporting bone 15 is pivotally connected to an intermediate portion of each receiving bone 13, and the other end of the supporting bone 15 is connected to the slider 4 which slides in the axial direction of the hollow column 1. Each is pivotally attached to a single supporting bone wheel 16 which slides (see FIG. 1).

The receiving bone 13 is mounted between the columns of the slider 4, and the distance between the receiving bone wheel 14 and the supporting bone wheel 16 is widened with the umbrella open, and when the umbrella is closed, these distances are increased. The length of each supporting bone 15 and the pivotal connection position between each supporting bone 15 and the receiving bone 13 are determined so as to reduce the interval (FIG. 1).
And FIG. 2).

An opening coil spring 11 whose upper and lower ends are in pressure contact with each other is interposed between the stopper 3 which is integral with the receiving bone wheel 14 and the supporting bone wheel 16. Is inserted into the hollow stopper 3 and receives the receiving wheel 14 therein.
In the meantime, the umbrella is compressed when the umbrella is closed, is expanded when the umbrella is opened, and presses the receiving bone wheel 14 to its upper limit position.

When the umbrella is closed, a closed umbrella engaging claw 22 for maintaining the umbrella is provided on the hollow column 1, and the umbrella can be engaged by being hooked on a hole provided on the stopper 3.

Next, a description will be given of the configuration of a portion that performs the closing operation, which is a characteristic component of the present invention. The slider 4 is 2
It has a book or more columns, the lower end of which is a stopper 3
The upper portion of the slider 4 is connected to an upper lid 5 which is integral with a cylindrical clutch 6 having a female claw F.

A compression coil spring 12 for closing the umbrella is inserted around the cylinder clutch 6, and the upper end of the coil spring 12 is adhesively bonded to the inside of the upper lid 5, and the lower end is adhesively bonded to the upper part 8 of the mandrel. (FIGS. 1 and 2).

A male claw M is integrally molded or incorporated in the upper part 8 of the mandrel. The male claws M on the upper part of the mandrel 8 are inserted into the locked female claws F of the slider 4 and the cylinder clutch 6, and the elasticity of the male claws M and the center line of the male claws M and the female claws F are shifted. As a result, the male claw M is rotated around the axis by the inclined engaging surface 7 of the female claw F, and the coil spring 12 for closing is twisted, and the male claw M engages with the female claw F by the restoring force (FIG. 1). ).

The upper part 8 of the mandrel is provided with a groove 26 into which a rotatable cam 24 mounted in the hollow column 1 is fitted. The groove 26 is formed so as to be inclined with respect to the axial direction. The male pawl M is made to rotate around the axis more than the width of the meshing portion of the female pawl F and the male pawl M of the clutch 6 (FIGS. 6, 7, 8, and 12).

At the time of opening the umbrella, a cam 24 which engages with the groove 26 and rotates and slides is mounted in the hollow support 1 at a position opposite to the groove 26 of the upper part 8 of the mandrel, and this cam 24 is a rigid wire. Umbrella handle 28 with piano wire 25
It is connected to the lower end of the column 21 of the locking device mounted on the nearby hollow column 1 (FIG. 10).

A push button 20 having a tongue ring mechanism for opening and closing the umbrella is connected to the umbrella closing claw 22.
A compression coil spring 23 for returning the tongue link mechanism to its original position is attached to the lower end of the spring. Reference numeral 27 denotes a cotter for preventing the umbrella handle 28 from rotating (FIGS. 3, 4, and 10).

First, the state in which the umbrella is closed will be described.
The stopper 3, the slider 4, and the mandrel 2, which are integral with the receiving bone wheel 14, the supporting bone wheel 16, and the supporting bone wheel 16, all approach the umbrella handle 28. Thus, the stopper claw 22 mounted in the hollow support 1 is engaged with the hole of the stopper which forms a part of the stopper 3. Also, the closing coil spring 12 in the slider 4 is in an extended state (FIG. 2).

In the above state, the foot 18 is pressed against the ground or the wall, and the umbrella handle 28 is pushed down while sliding against the umbrella handle compression coil spring 29, and the lower end of the mandrel 2 is pushed down with the end of the umbrella handle 28, The male claw M provided on the upper part 8 is inserted into the female claw F of the cylinder clutch 6 integrated with the slider 4 while being guided by the inclined engaging surface 7 of the female claw F, and the elasticity of the male claw M is closed. The male pawl M and the female pawl F of the cylinder clutch 6 are engaged by the torsional restoring force of the umbrella coil spring 12. The depressed umbrella handle 28 is returned by the umbrella handle compression coil spring 29.

Next, the operation and action of opening the umbrella will be described. When the locking claw 22 is released by depressing the button 20 as in the prior art, the resilience of the umbrella closing coil spring 12 pushing down the receiving bone wheel 14 is separated by the engagement of the male claw M and the female claw F. As a result, the opening coil spring 11 is extended by the elastic force, and pushes up the receiving bone wheel 14. With this rise, each receiving bone 13 is pushed up and spreads radially to expand the rib 17.

At this time, a supporting bone 15 is pivotally supported in the middle of each receiving bone 13, and a lower end of the supporting bone 15 is pivotally supported by a supporting bone wheel 16 integrated with the slider 4. The stopper 3 which is lifted up and integrated therewith rises together. The umbrella opening operation normally stops when the cloth stretched on the upper stopper 9 and the rib 17 is taut, that is, the umbrella stops in an open state.

Next, the operation and action of closing the umbrella will be described. When the push button 20 provided in the vicinity of the umbrella handle 28 is pressed down, the tongue link mechanism including the support 21 and the like, the support 21 slides on the axis of the hollow support 1 toward the umbrella handle 28 while compressing the coil spring 23, By pulling the piano wire 25 connected to the lower end of the support 21 in the direction of the umbrella handle 28, grooves 26 formed on both sides of the upper mandrel 8 are drawn.
The cam 24 is rotated and slid along the tongue so that the mandrel 2 is twisted around the axis, thereby rotating the male pawl M about the axis of the hollow column 1 and releasing the engagement with the female pawl F. Thus, the closing coil spring 12 is released from the compressed state.

The decompressed umbrella closing coil spring 12 is extended by its resilient force, pushes down the mandrel upper part 8 and compresses the umbrella opening coil spring 11 via the receiving bone wheel 14, and then receives the receiving bone wheel 14. Support bonebone 1
6 The entire slider 4 that is integral with the supporting bone wheel 16 is also pushed down, and the receiving bone 13, the supporting bone 15, and the ribs 17 are also folded and the umbrella is closed.

When the closing coil spring 12 has a sufficient elasticity, the locking hole of the stopper 3 is locked to the locking claw 22 provided in the hollow support 1. In order to reduce the weight, the elasticity of the umbrella closing coil spring 12 may only be used to close the umbrella, and the locking operation may be performed with both hands when the umbrella is closed.

The opening operation is performed by pushing down the push button 20. When the push button 20 starts to be opened, the button 20 is pushed up by the restoring force of the coil spring 23 and the locking claw 22 when the button 20 is released without releasing the button. The cam 24 connected by the wire 25 is also housed in the hollow column 1 and does not prevent the slider 4 from rising.

However, since the button 20 may be kept depressed, the slider upper lid 5 and the cylinder clutch 6
One end of the cam 24 is forcibly housed in the hollow column 1 by lifting up, and the other end of the cam 24 is formed with a groove 30 on the opposite side of the push-up portion of the upper cover 5 and the cylinder clutch 6 so as not to interfere.
(FIGS. 5 and 11).

As described above, at the time of closing the umbrella, one end of the cam 24 is pushed down by one end of the cylinder clutch 6 and is forcibly accommodated in the hollow column 1. At this time, the other end of the cam 24 is grooved in the cylinder clutch 6 so as not to be an obstacle. 31 are provided (FIGS. 5 and 11).

(Second Embodiment) Next, an automatic openable umbrella according to a second embodiment shown in FIGS. 13 to 20 will be described. The configuration of the portion that performs the opening operation is the same as that of the conventional one, as described in the first embodiment. That is, the rib 17 at the upper end of the hollow support 1 is
Are pivotally connected to each other, and the receiving bone 13
Are pivotally connected at one end, and the other ends of the receiving bones 13 are pivotally connected to a single receiving bone wheel 14 slidably fitted to the hollow column 1.

Further, one end of a supporting bone 15 is pivotally connected to an intermediate portion of each receiving bone 13, and the other end of the supporting bone 15 is slidably fitted to the hollow support 1.
Each of them is pivotally connected to a single supporting bone wheel 16 which slides in connection with 8 (FIG. 13).

The receiving bone wheel 14 is located closer to the tip of the umbrella than the slider 38 and the supporting bone wheel 16.
When the umbrella is opened, the distance between the supporting bone wheel 14 and the supporting bone wheel 16 is widened, and when the umbrella is closed, the distance between the supporting bone 15 and the supporting bone 1 is narrowed so that the distance between them is narrow.
5 and the receiving position of the receiving bone 13 are determined (FIG. 13).

Next, a description will be given of a configuration of a portion that performs the closing operation, which is a characteristic component of the present invention. The slider 3
Numeral 8 has two or more columns, and the slider 38 is bonded to the stopper 3 having the receiving wheel 16 and the male claw M by bonding or the like (FIGS. 13, 17, and 18).

A tension coil spring 39 is inserted between the slider 38 and the upper end of the mandrel 36 that slides in the axial direction on the outer periphery of the stopper 3. And is fixed to the upper end of the mandrel 36 (FIG. 13). The mandrel 36
A cylindrical clutch 32 having a female claw F is formed on the upper part of the cylinder clutch 32. As in the case of the first embodiment, the female claw F has an engagement surface 34 inclined in the axial direction.

By pressing the stone foot 18 against the ground or the wall with the umbrella handle 28 and pushing down the lower end of the mandrel 36, the mandrel 36 is moved toward the male claw M along the stopper 3 locked by the locking claw 22. When the female nail F on the upper part of the male nail M is pressed down, the male nail M has elasticity, and the male nail M is displaced from the center line of the female nail F. The pawl F is guided by the engaging surface 34 and twisted to cause twisting of the tension coil spring 39 for closing. The restoring force causes the male pawl M and the female pawl F to engage (FIG. 13).

In the lower part of the mandrel 36, a groove 26 into which the rotatable cam 24 mounted in the hollow column 1 is fitted.
The groove 26 is formed so as to be inclined with respect to the axial direction, so that the female nail F is rotated around the axis more than the width of the engaging portion of the male nail M and the female nail F. (Figure 1
3, FIG. 18, FIG. 20). The locking mechanism for maintaining the closed state is the same as in the first embodiment.

First, the state in which the umbrella is closed will be described. The receiving bone wheel 14, the integral supporting wheel 16, the stopper 3, the slider 38, and the mandrel 36 are all close to the umbrella handle 28.

The opening coil spring 11 is compressed between the stopper 3 and the receiving bone wheel 14, and the hole of the stopper that forms a part of the stopper 3 is inserted into the hollow support 1.
The locking claws 22 mounted inside are engaged with each other.
The closing tension coil spring 39 inserted between the slider 38 and the mandrel 36 is in a restored state in which the tension is released (FIG. 15).

In this state, the lower end of the mandrel 36 is pressed against the coil spring 29 of the umbrella handle 28 by pressing the foot 18 against the ground or the wall, thereby lowering the lower end of the mandrel 36. Press down with.

By this operation, the female claw F provided on the upper part of the mandrel 36 is pressed against the male claw M which is integral with the stopper 3 which is engaged with the hollow support 1, and the elasticity of the male claw M and the closure The male claw M is engaged with the female claw F by the restoring force of the extension coil spring 39. The depressed umbrella handle 28 is returned by the spring 29.

The operation and action of opening the umbrella are the same as those of the related art, and as described in the first embodiment, the button 20 is opened.
By pressing down, the umbrella stops in the open state.

Next, the operation and action of closing the umbrella will be described. When the cam 24 is rotated by pulling the piano wire 25 by depressing the button 20, the cam 24
Slides in the groove 26 provided at the lower part of the mandrel 3.
By applying a twist to 6, the female pawl F is rotated around the axis of the hollow column 1 to release the engagement with the male pawl M.

The closing coil spring 39 whose tension has been released is contracted by its resilient force, but the upper part of the mandrel 36 is fixed to the mandrel 36 so that the claw molded on the upper part of the mandrel 36 is formed. A support 33 is hung on a column 35 integral with the receiving wheel 14 and a ring 37 fixed to the end thereof, and is pulled downward to bring the receiving wheel 14 close to the supporting wheel 16.

As a result, the receiving bone 13, the supporting bone 15, and the rib 17 are folded, and the slider 38 integral with the supporting wheel 16 is also pushed down to close the umbrella.
