The movement restricting means 41 is constituted by left and right lock devices 42 such as latches attached to the lower end of the guide rail 11, for example.
[0030]
Further, as shown in FIGS. 1 to 5, the opening / closing device 1 is in contact with the groove portions 24 at portions other than the left and right engagement portions 23 which are projected from the side surface of the skirting board main portion 34 when the opening 3 is closed. An auxiliary movement restricting means 43 is provided as a sub-locking means for restricting the upward movement of the opening / closing body 21 by engagement so that the upward movement can be released.
[0031]
The auxiliary movement restricting means 43 is composed of, for example, a retrofit key unit 45 which is a left and right sub-lock device which is retrofitted to a substantially central portion in the vertical direction of the guide rail 11 with a mounting tool 44 such as a screw.
[0032]
The one-unit retrofit key unit 45 is, for example, substantially (can be retrofitted) attachable along the surface of a substantially central portion in the vertical direction of the flat plate portion 14 of the guide rail 11 of the completed opening and closing device 1. It has a rectangular plate-shaped mounting body 51.
[0033]
The attachment body 51 is provided with a movement restricting body 52 such as a substantially L-shaped plate-like slat hook bar for restricting the opening and closing body 21 from being lifted so as to be rotatable via a left-right rotating shaft 53. ing.
[0034]
The movement restricting body 52 is in a movement restricting state (a state pressed against the opening and closing body 21) in which the movement of the opening and closing body 21 is restricted by the rotation in one direction around the rotation shaft 53, and the rotation shaft 53 is moved. The pivotal movement in the other direction with respect to the center results in a movement permitting state (a state separated from the opening / closing body 21) that allows the opening / closing body 21 to rise. The movement restricting body 52 is formed with a finger hanging portion 54 as an operation portion by bending an edge portion. A substantially rectangular engagement hole 55 is formed in the movement restricting body 52 near the finger hook 54.
[0035]
In addition, an operation body 57 such as an operation lever for removably fixing the movement restricting body 52 in the movement allowable state to the attachment body 51 is attached to the attachment body 51 via a rotation shaft 58 in the front-rear direction that is the indoor / outdoor direction. It is provided rotatably. The operating body 57 is formed with an engaging projection 59 which engages with and disengages from the engaging hole 55 of the movement restricting body 52 by bending an edge.
[0036]
Further, the attachment body 51 is provided with a substantially block-shaped stopper 60 for preventing the movement restricting body 52 from rotating more than necessary in one direction and holding the movement restricting body 52 in the movement restricted state.
[0037]
Further, an urging body 61 such as a torsion spring for urging the distal end side of the movement restricting body 52 toward the opening / closing body 21 and pressing it against the surface of the opening / closing body 21 shrinks between the attachment body 51 and the movement restricting body 52. It is arranged in a state. That is, one end of an urging body 61 that urges the movement regulating body 52 in a direction in which the movement regulating body 52 rotates in one direction is attached to the attachment body 51 via the attachment piece 62, and the other end is It is attached to the movement restricting body 52 via the attachment piece 63.
[0038]
The movement restricting body 52 that is fixed to the attachment body 51 by the engagement between the engagement protrusion 59 and the engagement hole 55 is in a movement-permitted state. When the engagement with the engagement hole 55 is released, the engagement member 61 is urged by the urging body 61 to rotate in one direction about the rotation shaft 53 to be in a movement restricted state.
[0039]
In the movement restricting state, the movement restricting body 52 is urged by the urging body 61 so as to press against the surface of the opening / closing body 21, and the tip side of the movement restricting body 52 cuts into the groove 24 of the opening / closing body 21. And engages with this groove 24.
[0040]
Then, the bite engagement, which is a fitting engagement between the distal end side of the movement restricting body 52 and the groove 24 of the opening / closing body 21, restricts the rise of the closing state of the opening / closing body 21. The distal end side of the movement restricting body 52 has a shape corresponding to the groove 24 of the opening and closing body 21 and is formed in a tapered substantially triangular shape.
[0041]
When the movement restricting body 52 is returned to the movement allowable state, a finger is hung on the finger hook 54 to rotate the movement restricting body 52 in the other direction around the rotation shaft 53 against the urging force of the urging body 61. After the movement, the engagement protrusion 59 of the operation body 57 and the engagement hole 55 are engaged.
[0042]
Next, the operation and the like of the embodiment will be described.
[0043]
When closing the opening 3, the opening / closing body 21 is lowered while being unwound from the winding body 18, so as to be in a substantially flat closed state.
[0044]
When the opening / closing body 21 is lowered, the protruding engaging portion 23 moves over the lock device 42 to a position below the lock device 42, and as a result, the right and left lock devices 42, which are the movement restricting means 41, are moved. Thus, the opening of the opening / closing body 21 in the closed state is restricted by the engagement with the two engaging portions 23 on both lower ends of the opening / closing body 21.
[0045]
Further, when the engagement between the engaging projection 59 and the engaging hole 55 is released by the rotation operation of the operating body 57 when the opening 3 is closed, the movement regulating body 52 is shown in FIG. As described above, the urging member 61 rotates in one direction about the rotation shaft 53 to be in the movement restricting state in which the urging member 61 is pressed against the surface of the open / close body 21 in the closed state.
[0046]
The left and right movement restricting bodies 52 in the movement restricting state are urged by the urging body 61 so as to press against the surface of the opening and closing body 21, and the tip side of the movement restricting body 52 is one of the opening and closing bodies 21. It engages with both ends of the groove 24 and engages with the groove 24. As a result, the left and right rear key units 45, which are the auxiliary movement restricting means 43, are portions other than the two engaging portions 23 of the opening / closing body 21. The engagement of the two groove portions 24 with both end portions restricts the lift of the open / close body 21 in the closed state.
[0047]
For this reason, even when an upward external force is applied to the open / close body 21 in the closed state when the opening 3 is closed, the movement of the open / close body 21 in the closed state is increased by both the movement restricting means 41 and the auxiliary movement restricting means 43. Is regulated, and the closed state of the opening / closing body 21 is maintained.
[0048]
When the opening 3 is opened, the opening and closing body 21 may be raised after the movement restricting body 52 in the movement restricting state is returned to the movement permitting state.
[0049]
In this manner, according to the above-described embodiment, the movement restricting means 41 for restricting the movement of the opening / closing body 21 in the opening movement direction by the abutment engagement of the opening / closing body 21 with the two engaging portions 23 is configured. The left and right lock devices 42 and the auxiliary movement restricting means 43 for restricting the movement of the opening / closing body 21 in the opening movement direction by biting engagement with the groove 24 at a portion other than the both engaging portions 23 of the opening / closing body 21. With the back key unit 45, the movement of the open / close body 21 in the closed state in the opening movement direction can be appropriately regulated, and for example, crime prevention can be enhanced.
[0050]
In addition, the rear-attached key unit 45 attached to the flat plate portion 14 of the guide rail 11 is pushed by the urging body 61 toward the opening / closing body 21 so that the tip end bites into the groove 24 and engages with the groove 24. Since the movement restricting body 52 is provided, the movement of the opening / closing body 21 in the closed state in the opening movement direction can be sufficiently and appropriately restricted.
[0051]
Furthermore, the retrofit key unit 45 that can be attached to and detached from the guide rail 11 does not need to be attached to a predetermined position of the flat plate portion 14 of the guide rail 11. 21 can be restricted from moving in the opening movement direction, and keys can be easily added.
[0052]
Further, for example, when a space for ventilation is held between the lower end portion of the opening and closing body 21 and the lower frame 16, even if the movement restricting means 41 cannot restrict the movement of the opening and closing body 21 in the opening movement direction, The movement of the opening / closing body 21 in the opening movement direction can be appropriately regulated by the retrofit key unit 45 as the movement regulating means 43.
[0053]
