[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an opening operation device for an automatically opening umbrella that is automatically opened by a pushing operation of a locking repeller.

[0002]

[Prior art]

 Generally, an automatically opening western umbrella (also referred to as a jump umbrella) 1 has a center rod 2, a hand 3 fixed to one end of the center rod 2 and the other end of the center rod 2, as illustrated in FIG. Upper rocker 4 fixed to a portion, a middle rocker 5 and a lower rocker 6 movably fitted to a middle rod 2, a plurality of ribs 7 pivotally connected to one end of the upper rocker 4, and one end A plurality of ribs 8 pivotally connected to the middle rocker 5 at the other end in the middle of the ribs 7, and one end pivotally connected to the lower rocker 6 and the other end to an intermediate part of the ribs 8. A plurality of sub-reincarnations 9, a coil spring 10 for automatic opening which is located between the inner and outer rotors and is externally fitted to the center rod, and is fitted to the side 3 of the center rod 2. An elastic material such as a rubber provided on the inner rod 2 between the upper and the inner locks 5, 6 and the locking pallet 11 and the umbrella cloth (not shown). It is constituted by the path 12.

Conventionally, as shown in FIG. 7, an umbrella opening operation device has a reciprocating lock hole 13 formed of a long hole parallel to the axial direction in the lower sliding cylinder portion 6A of the lower wheel 6, and the spring plate-made above-mentioned device. The repellant 11 is provided inside the center rod 2, one end of which is fixed, the other end of which is provided with a pressing operation portion 14, and a locking key portion 15 is provided near the operation portion. The key portion 15 and the operating portion 14 are always projected from the slits 16 and 17 provided in the center rod 2.

FIG. 7 shows a state in which the umbrella 1 is closed, that is, a state in which the cistern 11 is locked. The locking key portion 15 of the cistern 11 projects from the slit 16 and the crocodile locking hole of the lower wheel 6 is shown. It is fitted in 13 and is locked to the locking end 13A. Therefore, when opening the umbrella, if the pushing operation portion 14 is pushed with a finger in a direction indicated by an arrow a in the figure, the crater 11 is bent as shown by a two-dot chain line 110 in FIG. Since the submersion sinks into the slit 16 and disengages from the locking end 14A of the lower wheel 6, the elastic force of the spring 10 causes the lower wheel 6 to slide automatically in the direction shown by the arrow B in FIG. Is opened (see Japanese Utility Model Publication No. 42-12118).

[0005]

[Problems to be solved by the device]

 By the way, in the prior art shown in FIG. 7, the umbrella is vigorously opened at the same time when the pressing operation portion 14 of the cistern 11 is pressed with a finger. When it is not necessary to open the umbrella, the umbrella may be opened by unintentionally pressing the pressing operation unit 14 with the hand holding the hand, or in a crowded place, the surrounding people may accidentally contact and open the umbrella. There is a fear that it will bother others and harm others.

The present invention has been made in view of the above situation, and an object of the present invention is to push the umbrella opening operation section unintentionally with a hand holding the hand or to contact with another person. It also aims to provide an umbrella opening operation device for an automatic opening Western umbrella that does not open the umbrella unexpectedly.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, a center rod having a hand at one end, an upper lock attached to the other end of the center rod, a middle lock and a lower lock movably fitted to the center rod, and a center rod. An automatic opening western umbrella provided with a locking repellency provided near the hand and a spring for driving the lower wheel in the umbrella opening direction, wherein the lower wheel is provided with a repellant locking portion. The first and second locking hooks are provided at arbitrary intervals, and stoppers that are locked to the crow's hook locking portion of the lower lock when the burrs are immersed are provided at opposite positions between the hooks. It is characterized (Claim 1).

In the fully closed state, as shown in FIG. 1, the first locking key portion of the repeller is fitted and locked in the crater locking hole of the lower lock. When the repelling operation portion is pressed with a finger in this state, the first and second locking key portions of the repelling are depressed, and at the same time, the stopper is inserted into the reclining locking hole of the lower lock. At this time, the first locking key part of the swordfish escapes from the swordfish locking hole of the lower wheel, and at the same time, the lower roller moves along the center rod in the direction of the middle roller with the elastic force of the spring to open the umbrella. However, the locking hole is locked by the stopper, and the movement of the lower wheel is temporarily stopped (see FIG. 2).

[0009] Therefore, when the finger is released from the operating portion of the repellent or the pressing force is released, the repelling force is restored by its elastic force, and at the same time when the first and second locking key portions are advanced, the stopper is remarked. The second locking hook enters the locking hole and the lower lock moves slightly in the direction of the middle lock due to the elastic force of the spring, but the second locking hook locks the second lock. The hole is locked, the movement of the lower wheel is blocked, and the umbrella is kept closed (see Fig. 3).

Therefore, even if the operation unit of the repellent is unintentionally pressed by the hand or accidentally brought into contact with another person, the umbrella does not open suddenly and is safe. Then, if you push the operation part of the cistern with your finger, the second locking key part of the cistern will come out of the cistern locking hole of the lower rocker and will retract, releasing the locking of the lower rocker, so The elastic force moves in the direction of the middle wheel and the umbrella is automatically opened (see Fig. 4). At this time, the cissing stopper is slightly apart from the end of the lower rocker, and the lower rocker is not locked. Then, when the pressing force of the repellent on the operating portion is released, the repelling is restored and the first and second locking hook portions project from the center rod (see FIG. 5).

When the western umbrella is closed as shown in FIG. 1, when the lower rocker is moved toward the hand against the elastic force of the spring, the outer end of the lower rocker on the hand side is repelled. The second and the first locking key portions of the above are sequentially pressed to be retracted, and the first locking key portion is fitted into the crater locking hole of the lower lock, and at the same time, the crater is restored and the first locking key portion is The locking hole is locked to the closed state. At this time, the cissing stopper does not come into contact with the lower lock, and therefore the umbrella closing operation is performed smoothly.

In addition, according to the present invention, since the length of the central rod longitudinal direction of the reciprocating locking hole of the lower locker is such that both the key portions can be simultaneously fitted, during opening and closing operations, The number of times the first and second locking key portions of the cistern are projected and retracted is minimized, smooth operation is performed, and design and manufacture are easy (claim 2). Further, according to the present invention, since the protruding length of the second locking key portion is made larger than the protruding length of the first locking key portion on the hand side, the crater locking hole of the lower lock has a second locking key. It is securely locked to the part, and it is possible to reliably prevent accidental opening of the umbrella.
