Description

  The present invention relates to a wilkey used to turn a handle, and more particularly to a wilkey capable of handling a plurality of handles of different sizes.

  When turning the handle of the valve installed in the fuel piping, water distribution pipe, steam piping, etc. to open and close the valve, to facilitate the turning operation of the handle in a narrow place, or to give a greater force to the handle In some cases, Wilkey may be used. As shown in FIG. 6, this wilkey is provided at one end of a rod-like operating rod 101 so that two holding legs 102 and 103 extending substantially perpendicular to the operating rod 101 face each other. Then, for example, the handle 104 as shown in FIG. 7 is used as follows. That is, the joint portion 104 c between the annular portion 104 a of the handle 104 and the straight portion 104 b is sandwiched by the holding legs 102 and 103, and the operating rod 101 is turned. As a result, the handle 104 is rotated and the valve 105 provided with the handle 104 is opened and closed.

  There are various sizes of the handle 104, and the diameter and thickness of the annular portion 104a of the handle 104 are set in accordance with the type and size of the valve 105, and the like. For this reason, it is necessary to select and use a wilkey in which the distance between the holding legs 102 and 103 conforms to the size and shape of the handle 104. However, the size and shape of the handle 104 are often found by going to the work site, and there is a case where the wheel key brought to the work site does not fit the handle 104. In this case, it is necessary to bring a compatible Wilky again, which takes time and effort. Also, for example, when the wilkey is small, there is a risk that the handle 105 may be shocked to turn the handle 104 and damage the valve 105, or the wilkey may come off the handle 104 and be injured when a force is applied. is there.

  Then, the Wilky which can respond to a plurality of steering wheels from which size differs is known (for example, refer to patent documents 1.). The wilkey has a rod-like operating rod, a fixed leg extended from the operating rod, and a movable leg slidably mounted along the operating rod and movable forward and backward with respect to the fixed leg. Furthermore, the fixed leg and the movable leg are in an end-spread shape that extends outward from the operating rod. Then, according to the size of the handle, the movable leg is slid and temporarily fixed with a bolt, and the handle can be rotated by turning the operating rod while holding the handle by the fixed leg and the movable leg. It is a thing.

Japanese Utility Model Publication No. 06-17874

  By the way, although a large force and torque may be required to turn the steering wheel, with the wheel key described in Patent Document 1, when the movable leg is temporarily fixed to the operating rod with a bolt, when the operating rod is rotated The bolt may be loosened and the movable leg may move. Then, when the movable leg moves, the fixed leg and the movable leg can not properly hold the handle, the force for turning the operating rod is released, and the worker holding the operating rod is shaken around. It will In addition, with such a wilkey, each time the handle is rotated, the movable leg must be slid according to the size and shape of the handle and temporarily fixed with a bolt, which requires time and labor.

  Therefore, an object of the present invention is to provide a can key that can handle handles of a plurality of sizes, and that can also turn the handle stably.

In order to solve the above problems, the invention according to claim 1 is that the end of the rod-like operating rod is provided with two clamping legs substantially perpendicular to the axial direction of the operating rod and extending in the same direction; The holding lever is turned by the two holding legs to turn the operating rod to turn the handle, wherein the holding legs are formed conically, and the distance between the holding legs is free from the operating rod side By lengthening toward the end side, handles having different sizes can be held by the two holding legs.

  According to the present invention, for a large handle, clamping is performed at the free end side of the clamping leg with a large distance between the clamping legs, and for a small handle, the operating rod side of the clamping leg with a small distance between the clamping legs Hold at (root side).

  The invention according to claim 2 is the wilkey according to claim 1, wherein the side surface of the holding leg is convex, and when the operating rod is rotated, the holding leg is positioned at the lower portion of the handle. It is characterized in that a retaining portion is provided for suppressing removal from the handle.

According to a third aspect of the present invention, in the wheel key according to the first or second aspect , the torque required to turn the handle is obtained in a state in which the handle is pinched on the free end side of the holding leg. It is characterized in that the length is set.

  According to the first aspect of the present invention, it is possible to cope with handles of a plurality of sizes with one wilkey just by changing the position of the holding legs sandwiching the handle. And since there is no need to move the holding legs, it is possible to turn the handle stably, and also to handle handles having different sizes easily and quickly, which is convenient. Further, since the distance between the holding legs is only increased from the operating rod side toward the free end side, the structure is simple, the manufacturing cost can be reduced, and moreover, it is robust and strong.

  According to the second aspect of the present invention, the retaining legs are provided to prevent the holding legs from coming off from the handle, so that even if the operating rod is rotated with a large force and torque, the holding legs are not removed from the handle It becomes possible to turn the handle stably.

Further , according to the invention of claim 1 , since the holding legs are formed in a conical shape, only by pushing the holding legs into the handle, the two holding legs hold the handle at a position according to the size of the handle. Easy and quick to handle different size handles, easy to use. In addition, by pressing the pinching leg into the handle, the pinching leg firmly clamps the handle, so that the handle can be stably turned without the pinching leg being detached from the handle. In addition, since the holding legs are formed in a conical shape only, the structure is simple, the manufacturing cost can be reduced, and moreover, they are robust and strong.

According to the invention of claim 3, the torque required to turn the handle can be obtained with the handle held by the free end side of the clamp leg having a large distance between the clamp legs, that is, with the large handle held. So that the length of the operating rod is set. That is, since the length of the operating rod is set to a length suitable for turning the large handle, it is possible not only to turn the large handle, but also to securely turn the fixed handle.

It is a front view of the conventional Wilky. They are a top view (a) and a front view (b) which show the state which is rotating the handle using the wheel key of FIG.

  Hereinafter, the present invention will be described based on the illustrated embodiments.

Embodiment 1
1 to 3 show this embodiment, and FIG. 1 is a front view showing a wilkey 1 according to this embodiment. The wilkey 1 is a steel tool used to turn a handle, and mainly includes an operating rod 2, two holding legs 3 and 4, and a retaining portion 5. Here, in this embodiment, the case of turning the handle 104 for opening and closing the valve 105 will be mainly described. As shown in FIG. 3, in the handle 104, three bar-like linear portions 104b radially extend from the central portion of the ring-shaped annular portion 104a, and the annular portion 104a and the linear portion 104b are joined at the joint portion 104c. It is joined by.

  The operating rod 2 is a round bar-like member extending straight, and the holding legs 3 and 4 are integrally formed on one end side, and the annular hook 21 is integrally formed on the other end side.

  The holding legs 3 and 4 are round rods and extend substantially in the same direction as the axial direction of the operating rod 2. Then, as described later, the joint portion 104 c of the handle 104 is sandwiched between the two holding legs 3 and 4, and the operating rod 2 is rotated to turn the handle 104.

  The distance between the holding legs 3 and 4 and the distance between the holding legs 3 and 4 increases from the operation rod 2 side (base side) to the free end side (tip end side), so that handles 104 having different sizes can be used as two holding legs 3. , 4 can be held. That is, as shown in FIG. 2, the holding legs 3 and 4 are formed in a conical shape (conical shape) with a large diameter on the operation rod 2 side, and the distance between the opposing holding legs 3 and 4 is from the operation rod 2 side It is wide toward the free end.

  Here, the taper angles (conical shape) and the arrangement position of the holding legs 3 and 4 are set so that a plurality of handles 104 having different sizes can be held by the two holding legs 3 and 4. For example, the distance between the holding legs 3 and 4 on the operation rod 2 side is D1, and the first handle 104 is sandwiched at this position, and the distance between the holding legs 3 and 4 on the free end side is D2 The shape and position of the holding legs 3 and 4 are set so that the second handle 104 (handle larger than the first handle 104) can be held at this position.

  The retaining portion 5 is a convex protrusion integrally provided on the side surfaces of the holding legs 3 and 4 and located at the lower portion of the handle 104 when the operating rod 2 is rotated. 4 to prevent the handle 104 from coming off. That is, in a state in which the handle 104 is held between the holding legs 3 and 4 (in a holding state in which the will key 1 can move slightly with respect to the handle 104), the operation rod 2 is formed to be positioned on both sides directly below the handle 104. Is positioned (engaged) directly below the handle 104 to prevent the holding legs 3 and 4 from coming off the handle 104.

  Specifically, in a state in which the handle 104 is sandwiched at the position of the distance D1, both sides of the sandwiching legs 3 and 4 directly below the handle 104 (the left and right sides of the opposing surface portion of the sandwiching legs 3 and 4 are shown in FIG. It is formed on the front side and the back side). Similarly, in a state in which the handle 104 is held at the position of the above-mentioned distance D2, the grip legs 3 and 4 are formed on both sides of the handle 104 immediately below. As described above, four retaining portions 5 are provided on each of the holding legs 3 and 4 and it is possible to turn the operating rod 2 to the left or right at the positions of the distances D1 and D2 The retaining portion 5 is located directly below the handle 104 to suppress and prevent the holding legs 3 and 4 from coming off the handle 104.

  On the other hand, the length of the operating rod 2 is set such that the torque required to turn the handle 104 can be obtained while sandwiching the handle 104 on the free end side of the holding legs 3 and 4. That is, the length of the operating rod 2 is such that the large torque required to turn the handle 104 can be obtained while sandwiching the relatively large handle 104 at the free end side where the distance between the holding legs 3 and 4 is large. It is set.

  Specifically, when the relatively large handle 104 is held at the above-mentioned distance D2, the length is set to be sufficient for turning the handle 104. Therefore, when the relatively small handle 104 is pinched at the above-mentioned distance D1, a torque larger than the torque normally required to turn the handle 104 is obtained. That is, it is longer than the length of the operating wheel of the conventional wheelie for the relatively small handle 104.

  Next, the operation and the like of Wilky 1 having such a configuration will be described.

  In order to turn the handle 104 using the wheel key 1, first, the joint 104 c of the handle 104 is pinched by the holding legs 3 and 4. That is, as shown in FIG. 3, when the pinching legs 3 and 4 are pushed into a portion where the annular portion 104a of the handle 104 intersects with the linear portion 104b, the pinching leg 3 is at a position corresponding to the size of the joint portion 104c. 4 sandwiches the joint portion 104c. For example, in the case where the handle 104 is relatively small, the holding legs 3 and 4 sandwich the joint portion 104c at the position of the above-described distance D1. Further, when the handle 104 is relatively large, the holding legs 3 and 4 sandwich the joint portion 104c at the position of the above-mentioned distance D2.

  In this state, the holding legs 3 and 4 hold the joint portion 104c to such an extent that the can key 1 can move somewhat with respect to the handle 104. Further, the retaining portions 5 of the holding legs 3 and 4 are located on the left and right sides directly below the handle 104 and are not engaged with the handle 104.

  Next, the operating rod 2 is turned and the handle 104 is turned. At this time, the wilkey 1 slightly moves relative to the handle 104, and the retaining portion 5 is positioned (engaged) directly below the handle 104, so that the holding legs 3 and 4 are prevented from coming off the handle 104.

  As described above, according to the present wilkey 1, it is possible to correspond to the handle 104 having a plurality of sizes with one wilkey 1, only by changing the positions of the holding legs 3 and 4 sandwiching the handle 104. Further, since the holding legs 3 and 4 are fixed to the operating rod 2 and there is no need to move the holding legs 3 and 4, the handle 104 can be stably rotated, and the handles 104 having different sizes can be easily and quickly. It is easy to use. In addition, since the distance between the holding legs 3 and 4 is only longer from the control rod 2 toward the free end, the structure is simple and the manufacturing cost can be reduced. is there.

  Furthermore, since the pinching legs 3 and 4 are formed in a conical shape, two pinching legs at a position according to the size of the handle 104 simply by pushing the space between the pinching legs 3 and 4 into the joint portion 104c of the handle 104. 3 and 4 sandwich the joint portion 104c, and can easily and quickly correspond to handles 104 having different sizes, which is convenient. Further, by pushing the holding legs 3 and 4 into the joint portion 104c of the handle 104, the holding legs 3 and 4 firmly hold the joint portion 104c, so the holding legs 3 and 4 do not come off the handle 104 and the handle 104 is stabilized. It becomes possible to turn it. In addition, since the holding legs 3 and 4 are formed in a conical shape, the structure is simple, the manufacturing cost can be reduced, and moreover, they are robust and strong.

  Further, since the retaining portion 5 is provided to prevent the holding legs 3 and 4 from coming off from the handle 104, the holding legs 3 and 4 can be treated with the handle 104 even if the operating rod 2 is rotated by a large force and torque. It becomes possible to turn the handle 104 stably without coming off.

  On the other hand, in the state in which the handle 104 is held by the free ends of the holding legs 3 and 4 having a large distance between the holding legs 3 and 4, that is, in the state holding the large handle 104, the torque required to turn the handle 104 is The length of the operating rod 2 is set to be obtained. That is, since the length of the operating rod 2 is set to a length suitable for turning the large handle 104, not only can the large handle 104 be properly turned, but even if a relatively small handle 104 or the like is fixed. It becomes possible to turn reliably.

In this embodiment, the shapes of the holding legs 6 and 7 are different from those of the holding legs 3 and 4 of the first embodiment, and the same reference numerals are given to the same configuration as that of the first embodiment to omit the description. .

  The holding legs 6 and 7 have a shape in which three cylinders having different diameters are connected in a step-like manner, and can hold three handles 104 having different sizes. That is, large diameter cylindrical portions 61 and 71 are provided on the operating rod 2 side, medium diameter cylindrical portions 62 and 72 are provided at the central portion, and small diameter cylindrical portions 63 and 73 are provided on the free end side . The distance between the holding legs 6 and 7 at the operation rod 2 is D3, the distance between the holding legs 6 and 7 at the center is D4, and the distance between the holding legs 6 and 7 at the free end is D5 ( It has become D3 <D4 <D5. Thereby, the large handle 104 is held at the distance D5, the middle handle 104 is held at the distance D4, and the small handle 104 is held at the distance D3. Here, although not shown, the retaining portions 5 may be provided on the cylindrical portions 61 to 63 and 71 to 73 of the holding legs 6 and 7 as in the first embodiment.

  According to this embodiment, as in the first embodiment, one wilkey 10 can correspond to the handle 104 of a plurality of sizes, and moreover, the handle 104 can be stably turned. Further, since the holding legs 6 and 7 are formed in a step shape, it is possible to easily visually check at which region the handle 104 is sandwiched and whether the handle 104 is sandwiched at an appropriate region.

  The embodiment of the present invention has been described above, but the specific configuration is not limited to the above embodiment, and even if there is a change in design or the like within the scope of the present invention, Included in the invention. For example, in the first embodiment, two handles 104 having different sizes can be held between the holding legs 3 and 4, but more handles 104 may be held. Further, although the retaining portions 5 are provided on both the holding legs 3 and 4, depending on the force required to turn the handle 104, torque, etc., they may be provided on only one holding leg 3 or 4.
