Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic umbrella, and more particularly to a safety device for preventing an accidental opening accident called an explosion.

[Conventional technology]

Automatically opening western umbrellas have been well known and have become the mainstream of western umbrellas in recent years due to the convenience of being able to open them with a single touch.

However, while the operation of opening the umbrella is simple, there is a risk that the umbrella may open accidentally due to careless operation, causing mental confusion or injuring people in the vicinity. be.

In order to prevent such risks, it is also known that a number of safety devices have been proposed to prevent the accidental opening of the umbrella.

[Problem to be solved by the invention]

A conventionally known safety device is one in which a locking device is provided on the push button for opening the umbrella (for example, the Utility Model Act published in 1983).
(Refer to Publication No. 32669). That is, when an automatic umbrella is closed, the lower potter's wheel located on the hand side is locked by a paddle, and by pushing the wheel into the middle rod, the lock is released and the lower potter's wheel is moved in front of the center rod. The umbrella is automatically moved by a spring to open the umbrella, and the known safety device is equipped with a locking device to prevent the repellent from being pushed in.

However, in the case of such a conventional example, the desired purpose can be achieved by operating the locking device and locking the repellent, but if the locking operation is forgotten, the function as a safety device will not change. There is. In particular, when opening and closing a Western umbrella frequently, it is extremely troublesome to operate the locking device each time, and it is difficult to force the umbrella owner to perform such operations.

By the way, Japanese Patent Publication No. 57-29161 discloses a safety device that can automatically provide the same effect as a lock without having to operate the locking device every time the umbrella is closed.

According to this known safety device, when the umbrella is in the closed state, the lower potter's wheel is locked to the locking claw of the repellent. Then, by pushing the push button of the repellent, the lower potter's wheel is released from the lock and temporarily enters the open umbrella position. This point is similar to the conventional automatic opening umbrella.

By the way, according to this known device, when the push button of the repellent is kept pressed, the lower potter's wheel, which has moved once, is engaged with the auxiliary pawl of the repellent at the opening start position and stopped at that position. Then, as the lower wheel moves to the opening start position, the umbrella rib becomes slightly open, so the user can easily notice that the pressing of the push button is a malfunction, and grasp the lower wheel. The umbrella can then be moved to its original closed position and locked again with the locking claw of the repellent.

However, in the safety device of Japanese Patent Publication No. 57-29161, the tail end of the repellent where the push button is located is formed into a hook shape, and the auxiliary claw is provided by this hook. This will cause problems. That is, the above-mentioned known safety device forms a hook part of the repellent in the area on the back surface of the push button, and when the umbrella is closed, the lower end of the lower wheel is deeply inserted into the hook part, and the locking claw of the repellent is engaged with the lower wheel. Make it stop. Then, when the push button is pushed in to move the lower potter's wheel to the opening start position, the auxiliary pawl in the pushed-in hook part is locked to the auxiliary locking part of the lower potter's wheel, and the lower potter's wheel is moved to the opening start position. It is a structure that stops the Therefore, the distance between the umbrella closing position of the lower potter's wheel and the umbrella opening starting position where the auxiliary claw is used as a stopper is limited by the effective length of the hook, and has to be extremely short. receive. For this reason, even if the lower potter's wheel is stopped at such an opening start position, the opening of the umbrella rib will be slight, and the user may not be able to fully see this and may overlook this as a malfunction. There is.

Regarding this point, if the hook is made long, the auxiliary pawl can be provided corresponding to the position where the lower potter's wheel is sufficiently advanced. A locking claw of the repellent is provided in the part, and since the auxiliary claw interferes with the locking part, it is practically impossible to form the hook part sufficiently long in this way.

Furthermore, each time the umbrella is opened and closed repeatedly, the auxiliary locking portion of the lower potter's wheel, which moves forward due to the strong umbrella opening spring, repeatedly hits the auxiliary pawl, but in the known safety device, the auxiliary pawl Its base is supported in a cantilevered manner by the hook, and there is nothing else to support it. Therefore, as the above-mentioned collisions are repeated, there is a problem in that the auxiliary pawl deforms and eventually bends.

In addition, in a structure in which a hook is provided by punching the tail end of a repellent into a U-shape, the entire hook has a fragile structure, and as the push button is repeatedly pressed, the hook gradually moves in the pushing direction. There is a risk that the auxiliary claw may become deformed and the auxiliary claw may no longer be able to function properly.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

(Overall Configuration of Western Umbrella) FIG. 7 shows an overview of the automatically opening Western umbrella, in which an upper potter's wheel 2 is fixed near the front end of the middle rod 1. A middle potter's wheel 3 and a lower potter's wheel 4, which are slidable in the longitudinal direction of the axis on the outer periphery of the center bar 1, are inserted in the middle of the center bar 1, and both potters' wheels 3 and 4 are mutually openable. It is urged in the direction of separation via a spring 5. A stopper body 6 is externally mounted on the middle rod 1 located below the upper potter's wheel 2, and the middle potter's wheel 3 hits the stopper body 6 and stops when the umbrella is opened. The middle rod 1 is made of a metal or synthetic resin pipe.

The proximal end of the master rib 7 is pivotally attached to the upper potter's wheel 2. The main rib 7 is preferably made of an extruded glass fiber material, has a pivot fitting 8 fixed to its base end, and has a synthetic resin tip 9 attached to its distal end.
The proximal end of the support bone 10 is pivotally attached to the middle potter's wheel 3,
The tip of the support rib 10 is pivotally attached to a bracket member 11 fixed to the middle part of the main rib 7. Further, the proximal end of the coronal bone 12 is pivotally attached to the lower potter's wheel 4, and the distal end of the columbar bone 12 is pivotally attached to the midway portion of the supporting bone 10. Therefore, due to this frame structure and the potter's wheel structure, when the lower potter's wheel 4 is in a free state, the middle potter's wheel 3 and the lower potter's wheel 4 are biased in the direction of separating from each other due to the action of the opening spring 5, and are pushed toward the front end of the middle rod 1. It slides and opens automatically as shown.

A hand 13 is attached to the tail end of the middle rod 1, and a repellent 14 is attached to the middle rod 1 at a forward position near the hand 13.
It is equipped with 3. This repellent 14 is equipped with a push button 15 at the tail end, and is elastically supported so that it can be pushed in the radial direction of the center rod 1 and restored freely by pressing the push button 15. 4 is moved near the hand, the lower potter's wheel 4 is locked.

(First Example) In the first example shown in FIGS. 1 and 2,
The middle rod 1 has one side opening 16 located opposite to each other in the radial direction.
and an opening 17 on the other side. Correspondingly, the repellent 14 includes a first locking claw 18a and a second locking claw 18b that are retractable from the opening 16 on one side, and an auxiliary claw 19 that is retractable from the opening 17 on the other side. We are prepared. That is, when the repellent 14 rebounds, the first locking claw 18a and the second locking claw 18
b protrudes from the opening 16 on one side, while the auxiliary claw 19
is recessed from the other side opening 17, and the tip of the auxiliary claw 19 is positioned within the other side opening 17 as shown in the figure. However, when the repellent 14 is pushed through the push button 15, the first locking claw 18a and the second locking claw 18b retract from the opening 16 on one side, while the auxiliary claw 19 protrudes from the opening 17 on the other side. It is composed of The opening 16 on one side is formed in the shape of a long slit through which the first and second locking pawls 18a and 18b can be inserted and retracted, while the opening 17 on the other side is formed in the shape of a hole through which the auxiliary pawl 19 can be inserted and retracted. has been done.

Therefore, the auxiliary pawl 19 is located on the opposite side of the first and second locking pawls 18a and 18b, and
Since it can be provided at a position sufficiently far away in the axial direction forward of the repellent 14, the amount of movement of the lower potter's wheel 4 as described later, that is, the opening that is temporarily stopped by the auxiliary pawl 19 from the umbrella closing locking position. It becomes possible to ensure sufficient release to the starting position.

The sleeve 4a of the lower potter's wheel 4 has a first locking hole that can be freely engaged with the first locking pawl 18a when the lower potter's wheel 4 is moved to the closed position relative to the claw of the repellent wheel 14. 20a and the second locking claw 18b
A second locking hole 20b that can be freely engaged with is formed. Further, a safety locking hole 21 that can be freely engaged with the auxiliary claw 19 is formed on the other side of the sleeve 4a. The first locking hole 20a and the second locking hole 21
b is formed in the shape of a window hole, and the safety locking hole 21 is formed in the shape of a long slit that can function as described later.

The operation of this first embodiment will be explained: FIG. 1A shows the umbrella closed state, in which the lower potter's wheel 4 is moved near the hand 13, and the first locking hole 20a is opened by the first locking claw. 18a, the second locking hole 20b is locked to the second locking hole 18b, and stopped against the opening spring 5.
Therefore, in this state, the first locking pawl 18a and the second locking pawl 18b constitute the locking pawl described in the claims, and the first locking hole 20a and the second locking hole 20b
constitutes the locking portion described in the claims. However, regarding the structure of the locking claw and the locking hole, the first locking claw 18a and the first locking hole 2
The two locking structures of locking 0a and locking of the second locking pawl 18b/second locking hole 20b are not necessarily required, and it is sufficient to have either one of the locking structures.

From this state, when the push button 15 of the repellent 14 is pushed, the repellent 14 is pushed and the first locking pawl 18a and the first locking hole 20a are locked, and the Second locking claw 18b/second locking hole 20
b is released, and the lower potter's wheel 4 is released from the opening spring 5.
Due to this action, the inner rod 1 moves forward from the umbrella closing position. However, at this time, Hajiki 14 was pushed.
The auxiliary pawl 19 enters and locks into the safety locking hole 21 of the lower wheel 4, and the lower wheel 4 is stopped at the opening starting position. At this time, the tail edge of the safety locking hole 21 strongly hits the auxiliary claw 19, and a force acts in the direction of bending and deforming the auxiliary claw 19, but the opening 17 on the other side of the center rod 1 Since the auxiliary claw 19 can be held,
Bending deformation of the auxiliary claw 19 is suitably prevented.

Due to the stopper action of this auxiliary claw 19,
As the lower wheel 4 moves to the opening start position, the main rib 7 becomes slightly open, so the user easily notices that the pressing of the push button 15 is a malfunction and grips the lower wheel 4. Then, the umbrella can be moved to the original closed position and locked again with the locking claw of the repellent. Regarding this point, as mentioned above, since the auxiliary pawl 19 is provided at a position sufficiently distant from the push button 15, the safety locking hole 21
By forming the main rib 7 to be long, the half-open state of the main rib 7 can be set to a sufficiently open position that can be easily recognized visually.

The temporary stop position at the opening start position is set such that the second locking hole 20b of the upper potter's wheel 4 is located above the first locking claw 18a of the repellent 14.
Therefore, as shown in FIG. 1C, when the push button 15 is released and the repellent 14 is returned to its resilient state, the auxiliary pawl 19 is disengaged from the safety locking hole 21, and the lower wheel is released. 4 moves slightly in front of the center rod 1, but at the halfway point when the umbrella is opened, the first locking claw 18a of the repellent 14 immediately locks into the second locking hole 20b of the lower potter's wheel 4, and the lower potter's wheel 4 to stop. That is, the first locking claw 18a and the second locking hole 2
0b constitutes a safety locking portion according to claim 2. Therefore, in this state, the user checks whether or not pressing the push button 15 is a malfunction, and if it is a malfunction, the user grasps the lower potter's wheel 4 and moves it to the original closing position to engage the repellent. All you have to do is lock it with the stopper.

If the pushing operation is not a malfunction and the user intends to open the umbrella, it is sufficient to push the push button 15 again as shown in FIG. 1D. By this pushing again, the safety locking portion releases the locking of the lower wheel 4, and the lower wheel 4 freely moves forward to open the umbrella.

By the way, in order to close a Western-style umbrella, the lower potter's wheel 4 can be pulled toward the user's hand along the middle rod 1 and moved as in the conventional manner. At this time, first, the end edge 4b of the sleeve 4a on the lower potter's wheel is pressed against the first locking claw 18a.
The repellent 4 is inserted into the opening 16 on one side. A second locking hole 20b is provided on the first locking claw 18a.
When the is located, Hajiki 4 returns to its original state. Next, the connecting portion 4d between the second locking hole 20b and the first locking hole 20a engages with the first locking claw 18a, and the repellent 4 is re-inserted into the opening 16 on one side, and the other The auxiliary pawl 19 protruding from the side opening 17 enters the safety locking hole 20. If you move the lower potter's wheel 4 toward your hand, the first locking hole 20a will be located above the first locking pawl 18a.
However, with the second locking hole 20b positioned above the second locking claw 18b, the repellent 4 is elastically restored, and the position shown in FIG.
Lock the lower potter's wheel 4 in this state.

(Second Embodiment) In the second embodiment shown in FIGS. 3 and 4,
The middle rod 1 opens an opening 16 on one side and an opening 17 on the other side, and the sleeve 4a of the lower wheel 4 opens the first locking hole 20.
It is the same as in the first embodiment that the second locking hole 20b is provided on one side and the safety locking hole 21 is provided on the other side. In addition, the repellent 14 is
The locking claw 18 corresponds to the first locking claw 18a of the embodiment.
The provision of the auxiliary locking pawl 19 is also the same as in the first embodiment.

By the way, this second embodiment differs from the first embodiment described above only in that the second locking pawl 18b of the first embodiment is not required and is removed.

That is, according to the second embodiment, when the lower potter's wheel 4 is in the umbrella closing position, the locking pawl 18 is in the first locking hole 20.
It is locked at a. When the push button 15 is pushed in and released from the lock, the lower potter's wheel 4 moves to the opening start position,
At that position, the auxiliary claw 19 is locked in the safety locking hole 20 and stopped. In this state, when the pushing operation of the push button 15 is released and the repellent 14 is elastically restored, the lower potter's wheel 4 is slightly moved and the second locking hole 20b is locked with the locking pawl 18 at the halfway position where the umbrella is opened. and stop. Therefore, this second locking hole 20b and the locking claw 18
This constitutes a safety locking portion according to claim 2. When the push button 15 is pressed again, the lock between the lock claw 18 and the second lock hole 20b is released, and the lower wheel 4 moves freely to open the umbrella.

(Third Example) In the third example shown in FIGS. 5 and 6,
The middle rod 1 has an opening 16 on one side and an opening 17 on the other side, and the repellent 14 has a first locking claw 18a and a second locking claw 18b on one side, and an auxiliary claw 19 on the other side. This is the same as in the first embodiment. Also,
It is also similar to the first embodiment that the lower potter's wheel 4 has a safety locking hole 21 corresponding to the auxiliary pawl 19, but the lower potter's wheel 4 has a safety locking hole 21 corresponding to the auxiliary pawl 19.
A corresponding locking hole 20 is provided spanning both the locking claw 18a and the second locking claw 18b.

By the way, the difference between this third embodiment and the first embodiment is that in the first embodiment, the first locking hole 20a and the second locking hole 20b are two divided holes. The third embodiment has one locking hole 20 in which both holes communicate with each other.

That is, according to the third embodiment, when the lower potter's wheel 4 is in the umbrella closing position, the second locking pawl 18b engages with the locking hole 20,
Specifically, it is locked to the edge 4b of the sleeve.
When the push button 15 is pushed in and released from the lock, the lower potter's wheel 4
moves to the opening start position, and at that position the auxiliary claw 1
9 is locked in the safety locking hole 20 and stopped. From this state, release the pushing operation of the push button 15 and press the
4 is elastically restored, the lower potter's wheel 4 moves slightly in the middle of the opening position, and the locking hole 20 (edge 4
b) is locked and stopped by the first locking pawl 18a.
Therefore, the locking hole 20 and the first locking pawl 18a constitute a safety locking portion as set forth in claim 2. When the push button 15 is pressed again, the first locking pawl 18a and the locking hole 20 are unlocked, and the lower potter's wheel 4 moves freely to open the umbrella.

[Effects of the Invention] According to the present invention as set forth in claim 1, when the push button of the repellent is kept pressed,
Once the lower potter's wheel has moved, it locks with the auxiliary claw of the hatchet at the umbrella opening starting position and stops at that position. Since the umbrella is in the open state, the user can easily notice that the pushing of the push button is a malfunction, grasp the lower potter's wheel, move it to the original closing position, and lock it again with the locking claw of the pudding. This has the effect of preventing unexpected explosions.

According to the present invention as set forth in claim 2, from the point in time when the lower potter's wheel is engaged with the auxiliary claw of the barge and stopped while the push button of the barge is kept pushed in as described above, the push button is stopped. Even if the push-in operation is canceled and the repellent is allowed to recover elastically, the lower potter's wheel will be stopped by the safety locking part of the retractor at the halfway opening position, which is further moved from the opening start position, so this state will not occur. The user can check whether or not pressing the push button is a malfunction, and if the user intends to open the umbrella, the user can press the button again to open the umbrella.
By grasping the lower potter's wheel, moving it to the original closing position, and locking it to the locking claw of the repellent without pushing it in again, it is possible to prevent unexpected explosions.

The invention described in any of claims 1 and 2 has the following effects.

(a) Since the auxiliary pawl 19 is provided at a position sufficiently far away from the push button 15 forward from the push button 15 on the opposite side of the locking pawl 18 of the cissing machine 14, the auxiliary pawl 19 is located at a sufficient distance from the push button 15 to the stopper. As a result, the half-open state of the main rib 7 at the umbrella closing starting position can be set to a sufficiently open position that can be easily visually recognized from the outside. can.
Therefore, the intended purpose of allowing the user to easily discover malfunctions of the push buttons can be achieved.

(b) The safety locking hole 2 of the lower potter's wheel 4 advances due to the strong umbrella opening spring 5 each time the umbrella is opened and closed.
1 strongly hits the auxiliary claw 19 and exerts a force in the direction of bending and deforming the auxiliary claw 19. Since it is inserted into the other side opening 17 constituting the small hole, the auxiliary claw 19 can be held thereby and the bending deformation of the auxiliary claw 19 can be suitably prevented.

(c) Since the repellent 14 always inserts the tip of the auxiliary claw 19 into the other side opening 17, the repellent 14 is thereby positioned and the direction of the pushing movement of the repellent 14 is guided. Therefore, the repellent 14 does not sway horizontally, and the repellent 14 can be prevented from falling out of the slit-shaped opening 16 on one side.

(d) Unlike the complex-shaped repellent with a U-shaped hook as shown in Japanese Patent Publication No. 57-29161, the repellent 14 has a simple external shape, making it easy to manufacture and capable of low-cost production. Furthermore, the repellent 14 does not have any fragile parts and is solid and has excellent durability.
