FIG. 2 is an exploded explanatory view of the opener according to the embodiment.
From this figure, the structure of the opener according to the present invention is also clarified.
That is, the frame portion 10 includes a proximal end side frame portion 11, a central frame portion 12, and a distal end side frame portion 13.
The base end side frame portion 11 is made of a metal tube having a substantially L shape, and is formed of a circular tube 11m having a circular cross section extending from the base end portion to the curved portion, and an end portion on the center side thereof. Consists of a rectangular tube 11k having a quadrangular cross section.

On the other hand, the distal end side frame portion 13 has a configuration substantially the same as that of the proximal end side frame portion 11, but is arranged just symmetrically.
That is, the curved portion and the tip side are made of a metal circular tube 13m having a circular cross section, and the center side is made of a metal square tube 13k having a quadrangular cross section.
Thereby, both end portions of the central frame portion 12 made of the metal square tube body 12k having a quadrangular cross section are fitted into the center side end portions of the base end side frame portion 11 and the distal end side frame portion 13, and the frame The length can be expanded and contracted at the linear central portion of the portion 10.

The wire rod 15 inserted through the inside of the frame portion 10 is formed of a flexible tube made of a thin steel wire wound in a spiral shape, has flexibility, and is fixed to the proximal end side. When the operation unit 16 is rotated, the screw rod 17 fixed to the distal end portion of the wire rod 15 is also rotated.
Further, since the screw rod 17 at the distal end of the linear member 15 is screwed with a nut member 13 s provided at the distal end portion of the distal end side frame portion 13, the operation unit 16 is moved forward in the longitudinal direction of the linear member 15. Therefore, the intermediate part of the frame part 10 is expanded.
That is, both end portions of the central frame portion 12 are exposed to the outside from the central side end portions of the base end side frame portion 11 and the distal end side frame portion 13, and the length of the central portion is extended.

A nut portion 22 is provided on the proximal end side of the thumb turn clamping portion 20, and the nut portion 22 and the screw rod 17 at the distal end portion of the wire rod 15 are screwed together and fixed. When exchanging with another form of thumb-turn clamping part, this threaded connection can be released and easily separated and exchanged.
As already described, the attachment position of the grip portion 25 can be changed.
The mounting portion 30 is provided with a male screw portion 31. In this embodiment, two portions, a downward direction and an upward direction, are provided, and one of these is selected, and the nut member 25n at the tip of the grip portion 25 is connected to the male screw portion. What is necessary is just to screw in the part 31. FIG.
In this embodiment, the extending direction of the rod-like body 26 on the distal end side of the grip portion 25 coincides with the extending direction of the central frame portion 12 of the frame portion 10. As a result, the position of the distal end portion of the distal end side frame portion 13 is indicated.

FIG. 3 illustrates a thumb turn clamping portion attached to the distal end portion of the opener according to the above embodiment, in which (A) is a perspective view, (B) is a plan view, and (C) is a side view. ing.
As described above, the thumb-turn clamping portion 20 in the present invention is detachably attached to the distal end portion of the wire rod, and includes two spring plates 21 and 21 provided at the distal end and a nut portion 22 on the proximal end side. have.

(A) The figure shows a state immediately before the thumb turn T is clamped. On the upper and lower planes S of the thumb turn T, a push button P for unlocking is provided, and the tip of the thumb turn clamping portion 20 is provided. The two spring plates 21 and 21 can sandwich the upper and lower planes S of the thumb turn T.
At this time, the spring plates 21 and 21 can simultaneously press the push button P provided on the plane S.
As a result, the thumb turn T is rotated.
In this figure, the guide member is not shown for clarity of illustration.

In the (B) and (C) views, guide members 23 and 23 provided on both sides of the spring plates 21 and 21 are shown.
These guide members 23 are provided to guide the spring plates 21 and 21 so as to be able to hold the thumb turn satisfactorily using a steel wire having flexibility and high toughness.
In this embodiment, three spring plates 21 are provided on both sides (up and down positions in the plan view of FIG. 5B).

FIG. 4 is a main part exploded view illustrating another embodiment of the frame part according to the present invention.
The frame portion according to this embodiment is formed of a metal tube having a circular cross section, all of the three frame portions constituting the frame portion.
That is, the configuration of both end portions of the central frame portion 12 is different from that of the above-described embodiment so that the central portion of the frame portion 10 can be extended and contracted in the short and long directions. Half of the body is formed by cutting out, and on the other hand, a small diameter tubular body having a smaller outer diameter and a large diameter tubular body are joined to the distal end side of the base end side frame portion 11 that is slidably connected thereto. Half of the latter large-diameter pipe is cut out.

Similarly, the other end portion of the central frame portion 12 is the same as the distal end side end portion structure of the proximal end side frame portion 11, and the proximal end portion of the distal end side frame portion 13 is the base of the central frame portion 12. In the same form as the end portion on the end side, these frame portions 11, 12, and 13 are connected to each other so that they can be expanded and contracted at the central portion, and cannot be rotated in the circumferential direction.
Thus, the structure which makes the center part of a flame | frame part telescopic and non-rotatable can be designed freely.

In the above embodiment, the frame portion of any type is formed from three components, but it can also be formed from two components.
That is, it is possible to form the frame portion of the present invention from the two components of the base end side frame portion and the distal end side frame portion.
This is because, for example, a configuration may be adopted in which the linear length on the central portion side of the base end side frame portion and the distal end side frame portion is formed long and one end portion is fitted into the other end portion.
However, it is highly desirable to prepare various lengths as the central frame part in order to ensure longer and shorter stretch lengths, and to select and use them appropriately according to the situation at the site. In the above-described embodiment, a frame portion composed of three components is employed.

As mentioned above, although embodiment of this invention was described, in this invention, various forms can be changed and implemented as follows.
The size, material, and the like of the frame portion according to the present invention can be set freely as appropriate.
However, since the inner diameter of the hole part of the door scope provided in the door is about 12 mm, the outer diameters of the frame part and the thumb turn clamping part according to the present invention are within this size.
Since the wire-shaped guide member can be narrowed toward the center side, there is no problem even if the outer diameter is formed larger than the inner diameter of the hole.

Further, the shape of the front end side frame portion is also substantially L-shaped, but this shape is not exactly L-shaped as it is, for example, on the curved side (lower side) of the vertical portion, in the left direction in FIG. It can also be a shape that bulges.
This is because, for example, even if an object is present at the upper door portion of the thumb turn, the thumb turn holding portion at the tip can be held by the thumb turn without any problem.
The shape of the spring plate that holds the thumb turn is also free. In short, any shape can be used as long as it can hold the flat surfaces on both sides of the thumb turn, and the material is also elastic. If there is, you can choose freely.
In short, it is only necessary that the thumb turn can be sandwiched between two sandwich members.

The telescopic structure at the center of the frame is completely free. In the above embodiment, one end of the tubular body is configured to fit into the other end of the tubular body, but a long guide hole is formed in the axial direction at the end of the frame, and the other frame It is also possible to provide a projecting portion at the end so that the projecting portion engages and slides with the long guide hole.
Further, it is possible to implement the frame portion even if it is not necessarily a tubular body.

The wire rod is not limited to that used in the above embodiment, and a thin steel wire having flexibility may be used.
The configuration of the operation unit can also be freely designed, and in short, any configuration may be used as long as the operation unit can be rotated to rotate the linear member simultaneously.
The configuration of the screw rod provided at the tip of the wire rod and the nut portion of the thumb turn clamping portion screwed to this is not limited to this, both ends can be connected and detached, and mutual rotational motion can be achieved. Any structure can be used as long as it can be transmitted.

In the above embodiment, the grip portion is in the form of a screw driver. However, the shape of the grip portion can be freely changed, and any shape can be used as long as it can be grasped by hand.
Moreover, it is preferable to form the rod-shaped part of the grip part as long as possible.
This is because the thumb turn clamping portion is located on the extended line of the rod-like body, which is a guide.
Furthermore, this grip part can be attached to the lower part or upper part of the base end side frame part, or any position in the lateral direction.

This is because a plurality of attachment portions for the grip portion may be provided in advance on the base end side frame portion.
The form of the wire-shaped guide member can also be changed as appropriate.
As described above, the embodiments of the present invention have been described. However, in the present invention, by having the above-described configuration, even if the thumb turn is provided with a push button type locking mechanism or the thumb turn without the push button, the knob is securely pinched. It was possible to provide an opener that can unlock the thumb turn with extreme certainty.
