Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shutter device configured to pull up a shutter curtain stored at the lower end of an opening in a building to close the opening. [Prior Art] Conventionally, a drive mechanism and an opening/closing machine for winding and rewinding a shutter curtain are provided above an opening in a building such as a window, and the shutter is moved along guide rails erected at both left and right ends of the opening. In a shutter device configured to raise and lower a curtain to open and close an opening, an inspection port with an inspection lid pivoted to the ceiling is used to inspect and maintain the drive mechanism and opening/closing machine installed in the roof. It is formed horizontally in the part. However, with this model, the inspection opening is located on the same horizontal plane as the ceiling, so when performing inspection or maintenance work, the inspection lid must be opened upward or downward and the worker must put his or her upper body or whole body into the ceiling. The problem was that the user was forced to work in an awkward position and was unable to perform the work easily. [Problems to be Solved by the Present Invention] The present invention has been devised in view of the above-mentioned actual situation in order to eliminate the conventional drawbacks, and its purpose is to The object of the present invention is to provide a shutter device that allows easy inspection and maintenance of drive mechanisms such as drums and opening/closing devices.

[Means for solving the problem] In order to solve the problem, the technical means adopted by the present invention are as follows:
A shutter curtain wrapped around a winding shaft is provided to open and close building openings such as windows, and the shutter curtain is wound around a roof portion formed above the opening.
This shutter device has a built-in drive mechanism for rewinding and opening and closing, and is characterized in that an inspection lid that can be opened and closed vertically is pivotally mounted on the indoor side of the roof.

[Operations of the Invention] Therefore, according to the present invention, inspection and maintenance work of the opening/closing machine in the roof section, the hoisting tram, etc., and the maintenance work can be easily performed without forcing the worker into an unreasonable working posture.

[Example] The configuration of the present invention will be described in detail with respect to an example shown in the drawings.

In FIGS. 1 to 4, 1 is a bay window shutter installed at the opening of a building. A roof part 4 is arranged at the upper part of the window frame 2, and a shutter curtain 5a for the front A, left and right sleeve parts B, C at the lower part.
A base bag portion 6 for housing the shutter curtains 5b and 5C is integrally constructed and installed.

Inside the base bag portion 6, there are shutter curtains 5a, 5b,
Winding shafts 7a, 7b+70 for hanging the shutter curtains 5c are respectively pivotally supported at vertically offset positions, and an upper plate 8a is provided at the upper end of each of the shutter curtains 5a, 5b, 5c in the opening width direction. , 8b, 8c are attached.

Further, the roof portion 4 includes shutter curtains 5a, 5b,
A pair of hanging strips 9, 9... connected to both left and right ends of 5c.
A hoisting drum 10.10... for hoisting up the winding drum 10.10... and an opening/closing machine l1 for moving the hoisting drum 10.10... in the forward and reverse directions are arranged on the drive part assembly plate 4a. The shutter curtain 5a is guided by guide rails 13, 13, etc. installed in parallel with the vertical mullions 12, 12...
, 5b, 5c.

In the lintel part 4b of the roof part 4, elastic hollow bodies 14, 14... are provided to protrude downward in the width direction of the opening,
The opening is sealed by the contact of the upper plates 8a, 8b, and 8c.

As shown in FIG. 5, the upper frame 2a of the three-sided window frame 2 is fitted into the indoor end edge 4C of the drive unit assembly plate 4a, and the upper frame 2a is located at the rear of the upper frame 2a on the indoor side. The inspection M15 is provided in an upright position, and the inspection lid 15 is pivoted to a top plate 16 disposed above the roof portion 4 via a hinge 17 so as to be vertically movable.

In the configuration as described above, the shutter curtains 5a, 5
In order to open and close the three-sided windows A, B, and C using b, 5c, the opening/closing machine 11 is driven in forward and reverse directions, and the hoisting drums 10, 10, . . . , 9... is wound up and unwound, the hanging strip body 9
, 9... Shutter curtains 5a, 5b connected to
, 5c is a winding shaft}-7a, 7b, 7c,
The refill is activated.

If it becomes necessary to inspect or maintain the opening/closing device 11, the hoisting drum 10, 10, etc. or the hanging strips 9, 9, etc. during such lifting/lowering operation, the inspection lid 15 should be moved to the hinge 17.
If the roof section 4 is expanded upwardly through the roof section 4, the indoor side of the roof section 4 is completely opened, and the worker can easily work inside the roof section 4 without having to take an awkward posture.

In addition, in this embodiment, the indoor side edge 4 of the housing part assembly plate 4a
Although the upper frame 2a of the three-sided window frame 2 is fitted into c and the inspection lid 15 is provided in an upright position at the rear of the upper frame 2a on the indoor side, the present invention is not limited to this. As shown in FIG. 6, if the step part a is formed at the rear of the upper frame 2a and the inspection lid 15 is pivotally supported, the curtain rail 19 on which the curtain 18 is suspended can be attached to the three-sided window frame 2. It can be disposed above the opening and can prevent sunlight from leaking from the upper end of the curtain 18.

[Effects of the Invention] In short, the present invention provides a shutter curtain wound around a winding shaft to open and close building openings such as windows, and a roof formed above the opening. In the department,
In a shutter device that has a built-in opening/closing mechanism and an opening/closing mechanism that winds up, unwinds and rewinds the shutter curtain, an inspection lid that can be opened and closed vertically is installed on the indoor side of the roof. Inspection and maintenance of drive mechanisms such as opening/closing machines and hoisting drums installed in the building can be easily performed without requiring an unreasonable working posture.In addition, the indoor ceiling height can be secured and the living space can be improved. It has an extremely useful new effect that can be used more widely and effectively.
