It may be detachably attached to. In the range of the rotation angle in which the cutting direction of the engagement hole 17 and the rolling direction of the deformed portion 312a do not coincide with each other, the stopper 31 is rotatable with the stopper 31 being prevented from being detached from the horizontal frame 13.

  On the other hand, the distal end portion 311 of the stopper 31 is inserted into and engaged with a long hole 32 a of the fixing member 32 fixed to the lower portion of the back surface of the door 20. Hereinafter, as will be described in detail, the door stopper mechanism 30 according to the present embodiment is for releasing the locking state between the distal end portion 311 of the stopper 31 and the fixing member 32, that is, the door opening / closing restriction state from a remote position. Operating force transmission means is provided.

FIG. 4 is a perspective view showing the outer appearances of the fixed member 32 constituting the door opening / closing regulating means and the movable member 33 constituting the regulation releasing means according to the present embodiment.
The fixing member 32 fixed to the door 20 is a sheet metal member having a flat horizontal portion 321 and a flat vertical mounting portion 322, which are bent at a right angle, that is, in an L shape. The horizontal portion 321 is formed with a long hole 32a having an opening width that allows the first shaft portion 311a of the stopper 31 to be loosely fitted to allow the stopper 31 to slide. In addition, in the long hole 32a, fitting grooves 32b (position restricting portions) having a curvature diameter capable of fitting the second shaft portion 311b of the stopper 31 are formed at, for example, three locations.

  That is, the opening width of the long hole 32a is slightly larger than the diameter (first diameter) of the first shaft portion 311a, but smaller than the diameter (second diameter) of the second shaft portion 311b. Further, the diameter of curvature of the fitting groove 32b is slightly larger than the diameter (second diameter) of the second shaft portion 311b, but is smaller than the diameter (third diameter) of the flange portion 311c. Therefore, the stopper 31 is locked to the fixing member 32 by fitting the second shaft portion 311 b of the stopper 31 into the fitting groove 32 b of the fixing member 32.

  Here, in the present specification, a position where the second shaft portion 311b of the stopper 31 is fitted in the fitting groove 32b (position restricting portion) of the fixing member 32 is referred to as a “locking position”. Further, the position where the distal end portion 311 of the stopper 31 is lifted by the movable member 33 described below and the first shaft portion 311a is loosely fitted in the long hole 32a of the fixed member 32 is referred to as “non-locking position”. .

  At the end (the right end in FIG. 4) of the long hole 32a of the fixing member 32, an attaching / detaching groove 32c for allowing the stopper 31 to be attached / detached from the fixing member 32 is formed as necessary. That is, the curvature diameter of the attaching / detaching groove 32c is formed to be slightly larger than the diameter (third diameter) of the flange portion 311c of the stopper 31.

  In the vertical mounting portion 322 of the fixing member 32, mounting holes 32d and 32d for fixing the fixing member 32 to a predetermined position on the back surface of the door 20 with screws or the like, for example, are formed in two places, for example.

The movable member 33 is a sheet metal member that has a flat horizontal portion 331 and a flat vertical portion 332 that are bent at a right angle, that is, in an L shape. The horizontal portion 331 is formed with a long hole 33a having an opening width that allows the second shaft portion 311b of the stopper 31 to be loosely fitted to allow the stopper 31 to slide. The opening width of the long hole 33a is equal to or substantially equal to the curvature diameter of the fitting groove 32b of the fixing member 32. That is, the opening width of the long hole 33a is slightly larger than the diameter (second diameter) of the second shaft portion 311b of the stopper 31.
Further, the opening width of the long hole 33a is formed smaller than the diameter (third diameter) of the flange portion 311c of the stopper 31. Thereby, the flange part 311c of the stopper 31 inserted in the long hole 33a of the movable member 33 and the edge part of the long hole 33a contact | abut, and the stopper 31 is engaged in the state which does not remove | deviate from the movable member 33.

  An attachment / detachment groove 33c for allowing the stopper 31 to be attached to and detached from the movable member 33 as necessary is formed at the end (the right end in FIG. 4) of the elongated hole 33a of the movable member 33. That is, the attaching / detaching groove 33c is formed to have a slightly larger curvature diameter than the diameter of the flange portion 311c of the stopper 31. The curvature diameter of the attachment / detachment groove 33c of the movable member 33 is equal to the curvature diameter of the attachment / detachment groove 32c of the fixed member 32 described above.

  Guide pins 34, 34 (see, for example, FIG. 2) planted on the back surface of the door 20 are inserted into and engaged with the vertical portion 332 of the movable member 33 to guide the movement of the movable member 33. 33b and 33b are formed in two diagonally parallel places. The vertical portion 332 is formed with a connecting hole 33d to which one end of the operating force transmission means 26 is connected. In this embodiment, the operating force transmission means 26 is a wire, and the other end is connected to a locking rod 25 that reciprocates up and down in conjunction with the operation of the door opening / closing operation unit 24 described above. Thus, the door stopper mechanism 30 according to the present embodiment has a configuration in which the movable member 33 that releases the locked state of the stopper 31 and the fixed member 32 is interlocked by the operation of the door opening / closing operation unit 24, that is, the door The opening / closing operation part 24 also serves as a release operation part for releasing the door opening / closing restriction state.

  At the lower position where the movable member 33 is in contact with or close to the fixed member 32, the second shaft portion 311 b of the stopper 31 is fitted in the fitting groove 32 b of the fixed member 32. Therefore, in this specification, the lower position of the movable member 33 is referred to as a “locking setting position”. On the other hand, when the movable member 33 is lifted obliquely upward, the engagement between the second shaft portion 311b of the stopper 31 and the fitting groove 32b of the fixed member 32 is disengaged. It is called “stop release position”.

Next, the operation of the door stopper mechanism 30 configured as described above will be described.
First, as shown in FIG. 5, when the door opening / closing operation unit 24 is operated to the “open” position, the locking state of the door locking mechanism 23 is released, and the door 20 can be freely opened and closed. In conjunction with the “open” operation of the door opening / closing operation unit 24, the movable rod 25 at the end of the door 20 moves upward via the operation force transmission means 26, and the wire 26 connected to the movable rod 25 moves to the right. A tension (pulling force) T toward the surface is generated. Therefore, as shown in FIG. 6, the movable member 33 connected to the wire 26 is lifted obliquely upward to the right and moves to the above-described “locking release position”.

  When the movable member 33 is in the “unlocking position”, as described above, the distal end portion 311 of the stopper 31 is pulled up to the “non-locking position”, and the first shaft portion 311 a is the long hole 32 a of the fixing member 32. The second shaft portion 311b is slidable within the elongated hole 33a of the movable member 33. Thereby, the door stopper mechanism 30 does not operate, and the door 20 can be opened and closed freely.

  Next, when the door opening / closing operation unit 24 is operated to the “closed” position with the door 20 opened, the movable rod 25 at the end of the door 20 moves downward in conjunction therewith, and the wire tension is released. The As a result, the movable member 33 moves to the “locking setting position” in contact with or close to the fixed member 32 by its own weight. Note that biasing means (not shown) such as a spring may be provided, and the movable member 33 may be returned to the “locking setting position” by the biasing force.

  When the movable member 33 is in the “locking setting position”, the second shaft portion 311b of the distal end portion 311 of the stopper 31 shown in FIG. Drop onto and fit. Therefore, the opening / closing operation of the door 20 is restricted at the “locking position” where the second shaft portion 311b is fitted into the fitting groove 32b.

  In order to release the door opening / closing restriction state, it is only necessary to operate the door opening / closing operation unit 24 from the “closed” position to the “open” position. That is, when the door opening / closing operation part 24 is operated to the “open” position, the movable member 33 connected to the operating force transmission means 26 is pulled up to the “locking release position”, and the second shaft part 311b and the fitting groove 32b. Can be easily released.

(Second embodiment of door stopper mechanism)

In addition, about 2nd Embodiment, the same code | symbol is attached | subjected and demonstrated to the component which is common in the component of 1st Embodiment mentioned above.

  The movable member 43 according to the second embodiment shown in FIG. 8 includes a first horizontal portion 431a, a second horizontal portion 431c located on the lower right side of the first horizontal portion 431a, and first and second An inclined portion 431b connected to each end of the horizontal portions 431a and 431c is formed continuously. The first horizontal portion 431a, the inclined portion 431b, and the second horizontal portion 431c are loosely fitted with the second shaft portion 311b of the stopper 31 so as to allow the stopper 31 to slide left and right. Is formed.

  The opening width of the long hole 43a is equal to or substantially equal to the curvature diameter of the fitting groove 32b of the fixing member 32. That is, the opening width of the long hole 43a is formed to be slightly larger than the diameter (second diameter) of the second shaft portion 311b of the stopper 31. Further, the opening width of the long hole 43a is formed smaller than the diameter (third diameter) of the flange portion 311c of the stopper 31. Accordingly, the flange portion 311c of the stopper 31 inserted into the elongated hole 43a of the movable member 43 and the edge portion of the elongated hole 43a come into contact with each other, and the stopper 31 is engaged without being detached from the movable member 43.

The movable member 43 operates in conjunction with the operation of the door opening / closing operation unit as in the first embodiment described above. However, in the second embodiment, the “lock setting position” on the left side and the “lock” on the right side It is characterized by a horizontal reciprocation between the “releasing positions”.
That is, when the door opening / closing operation unit 24 is in the “closed” position, the movable member 43 is in the “locking setting position” shown in FIG. 8A, and the second shaft portion 311 b of the stopper 31 is caused by the weight of the stopper 31 main body. However, it falls and fits into any of the fitting grooves 32b of the fixing member 32. Since the stopper 31 is locked to the fixing member 32, the opening / closing operation of the door 20 is restricted.

  Further, in order to release the door opening / closing restriction state, it is only necessary to operate the door opening / closing operation unit 24 from the “closed” position to the “open” position. When the door opening / closing operation unit 24 is operated to the “open” position, the movable member 43 moves to the “locking release position” shown in FIG. In the process of moving the movable member 43 to the right, the flange portion 311c of the stopper 31 slides from the second horizontal portion 431c to the upper surface of the inclined portion 431b, and finally engages with the upper surface of the first horizontal portion 431a. The “unlocked position” is raised.

  When the movable member 43 is in the “locking release position” shown in FIG. 8B, the first shaft portion 311 a of the stopper 31 can slide within the long hole 32 a of the fixed member 32, and the second shaft The portion 311b can slide within the elongated hole 43a of the movable member 43. Thereby, the latching state of the stopper 31 and the fixing member 32 is released, and the opening and closing of the door 20 is permitted.
