The connecting member 81 is arranged in the elongated hole 64 of the engaging member 60 and moves relatively in the extending direction of the elongated hole 64 (moving direction M2 of the engaging member 60). Further, the connecting member 81 is arranged in the elongated hole 73 of the releasing member 70 and moves relatively in the extending direction of the elongated hole 73 (moving direction M3 of the releasing member 70).

The connecting member 81 is a guide member that guides the engaging member 60 and the releasing member 70 in the moving directions M2 and M3. The engagement member 60 is guided to the engagement position R1 and the release position R2 by the connecting member 81, and moves to the respective positions R1 and R2. Further, the releasing member 70 is guided to the first position S1 and the second position S2 by the connecting member 81 and moves to the respective positions S1 and S2.

The handle 40 (see FIG. 4) has a protrusion 44</b>A provided inside the cover 44 and an engaged portion 49. The protrusion 44</b>A is provided on the shielding surface portion 46 of the cover portion 44 and projects from the shielding surface portion 46 to the inside of the cover portion 44. The engaged portion 49 is a step portion formed between the projecting end surface of the protrusion 44A and the shield surface portion 46. The engaging member 60 at the engaging position R1 brings the engaging portion 61 into contact with the engaged portion 49, and the engaging portion 61 engages with the engaged portion 49.

The engaging member 60 holds the engaged portion 49 by the engaging portion 61 and holds the handle 40 at the operation position P1. The engaged portion 49 is caught by the engaging portion 61 of the engaging member 60, and the movement of the handle 40 to the folding position P2 is prevented. When the engaging member 60 moves from the engaging position R1 to the releasing position R2 (see FIG. 10), the engaging portion 61 is disengaged from the engaged portion 49, and the engaging portion 61 moves toward the engaged portion 49. The engagement is released. As a result, the engagement of the engaging member 60 with the handle 40 is released.

FIG. 11 is a cross-sectional view showing the handle device 6 of the present embodiment, and shows the handle device 6 in a state where the handle 40 is arranged between the operation position P1 and the folding position P2, similarly to FIG.
When the handle device 6 is folded, the release member 70 is pushed to move the release member 70 from the first position S1 to the second position S2 (see FIGS. 4 and 10). The releasing member 70 moves the engaging member 60 from the engaging position R1 to the releasing position R2 to release the engagement of the engaging member 60 with the handle 40. In that state, the handle 40 is moved from the operation position P1 to the folding position P2 (see FIGS. 11 and 3), and the handle device 6 is folded. The accommodating portion 34, the engaging member 60, and the releasing member 70 are accommodated in the cover portion 44 of the handle 40 and are covered by the cover portion 44.

After moving the handle 40 from the operation position P1, the release member 70 is released from the pressed state (see FIG. 11). The engaging member 60 contacts the protrusion 44A of the handle 40, is pressed by the protrusion 44A, and is held at the release position R2. While moving the handle 40 toward the folding position P2, the engaging member 60 disengages from the protrusion 44A, and the biasing member 80 biases the engaging member 60 from the release position R2 to the engaging position R1. .. At the same time, the release member 70 moves from the second position S2 to the first position S1 (see FIG. 3).

When operating the handle device 6, the handle 40 is moved from the folded position P2 toward the operation position P1 (see FIGS. 3 and 11). At that time, the cover of the handle 40 by the cover portion 44 and the release member 70 is gradually removed, and the storage portion 34 and the release member 70 are exposed. Further, the engagement member 60 contacts the protrusion 44A of the handle 40, is pushed by the protrusion 44A, and moves from the engagement position R1 toward the release position R2. At the same time, the release member 70 moves from the first position S1 toward the second position S2.

When the handle 40 moves to the operation position P1 (see FIGS. 10 and 4), the contact portion 48 of the cover portion 44 contacts the support member 30 and stops the handle 40. Further, the engaging member 60 is disengaged from the projection 44A, and the urging member 80 urges the engaging member 60 to the engaging position R1. As a result, the engagement member 60 is arranged at the engagement position R1 and automatically engages with the handle 40 (engaged portion 49). At the same time, the release member 70 moves to the first position S1 and is arranged at the first position S1.

The engagement member 60 holds the handle 40 in the operation position P1 and prevents the handle 40 from moving to the folding position P2. In that state (see FIG. 5 ), the handle 40 is rotated, and the handle 40 rotates the support member 30 and the rotating shaft 52 of the opening/closing mechanism 5. The handle device 6 is operated by the handle 40 to drive the opening/closing mechanism 5. The handle device 6 operates the opening/closing mechanism 5 and the opening/closing of the shoji 2 to open/close the shoji 2.

With the handle device 6 described above, the handle device 6 and the handle 40 can be stably operated. Further, when the handle device 6 is folded, the cover portion 44 of the handle 40 can make the portion used for holding the handle 40 and releasing the hold of the handle 40 inconspicuous. Therefore, the appearance of the handle device 6 and the fitting 1 can be improved.

The cover portion 44 of the handle 40 can prevent the release member 70 and the first opening 39A of the accommodating portion 34 from being exposed, and make the peripheral portion of the release member 70 more inconspicuous. Further, the engaging member 60 and the releasing member 70 can be easily accommodated in the accommodating portion 34 that extends from the base portion 31 of the supporting member 30. The accommodating portion 34 is arranged along the handle 40 in the cover portion 44. Therefore, the handle device 6 can be made compact, and the housing portion 34 can be surely covered by the cover portion 44.

By the biasing member 80, the engaging member 60 can be held at the engaging position R1 and the engaging member 60 can be reliably engaged with the handle 40. Since the engaging member 60 and the releasing member 70 are connected to the supporting member 30 by the single connecting member 81, the structure of the handle device 6 can be simplified. With the guide portion 30A of the support member 30, the release member 70 can be smoothly moved to the first position P1 and the second position P2.

The housing 34, the engaging member 60, and the release member 70 may be entirely housed in the cover 44 and covered by the cover 44. The container 34, the engaging member 60, and the release member may be released. A part of each of the members 70 may be housed in the cover portion 44 and covered by the cover portion 44. Further, the handle 40 may be connected to the support member 30 by a connecting means other than the connecting member 81 (for example, a pair of connecting protrusions formed on the handle 40). The releasing member 70 may be moved by an operation other than pushing (for example, pulling or sliding) to release the engagement of the engaging member 60 with the handle 40 by the releasing member 70. The engaging member 60 may be manually moved from the releasing position R2 to the engaging position R1 by the releasing member 70 so that the engaging member 60 is manually engaged with the handle 40.

The example in which the fitting 1 is a vertical sliding window has been described above, but the fitting 1 may be another window (for example, a horizontal sliding window, a raising/lowering window) or a fitting other than a window (for example, a louver). .. The handle device 6 can be provided in various fittings. Further, the present invention is not limited to the handle device for joinery, and can be applied to various foldable handle devices.
