Description

  The present invention relates to a barrier-free horizontal roll screen device mounted on a building opening frame for the purpose of insect-proofing, dust-proofing, light-shielding, blindfolding, decoration, and the like, and an assembly manufacturing / installation method thereof.

2. Description of the Related Art Conventionally, a barrier-free roll-drawing apparatus that is laterally drawn has been known as disclosed in Patent Document 1, for example.
In this type of barrier-free horizontal screen device, basically, a screen frame fixed to a building opening frame is arranged between a pair of right and left opposing fixed frames and the upper and lower ends thereof. The upper and lower rails to be installed, a movable rail formed to be movable in the open / close direction by lateral pulling, and supported by one of the fixed frames wound around the winding shaft and moved laterally. And the screen that is wound or unwound on the winding shaft, and curvedly enters and exits from the lower end of the fixed frame or the movable beam as the movable beam moves laterally. A guide is provided by slidingly engaging an engaging member provided along the lower end edge of the screen linearly along the lower end edge of the screen extended from the shaft and in an upper surface engaging groove. With a screen guide to It is.

  In installing the screen device having such a configuration in the building opening, in order to make the building opening where the screen device is installed barrier-free, the lower rail is fixedly disposed on the lower frame of the building opening. However, it is not satisfactory in terms of strength to be used as a part of the frame material that surrounds the four circumferences of the screen device. Therefore, a pair of left and right fixing members constituting the screen frame are used. Rather than assembling the frame and the upper and lower rails connecting the upper and lower ends into a single frame, the screen device is installed rather than assembling the other components of the screen device to the screen frame. The above-mentioned pair of fixed frames and the upper and lower rails positioned between the upper and lower ends are individually attached to the building opening frame to be installed. Later, to four sides of the screen frame which is installed in the building opening frame, as the assembly of the other components of the screening device is appropriate, it is also considered to make such a construction.

  However, if the above-mentioned pair of fixed frames and the upper and lower rails positioned between the upper and lower ends are individually attached to the building opening frame, the building opening frame itself is installed within the allowable dimensional error. However, if there is a certain dimensional error, it is necessary to assemble the components of the screen device so as to absorb the dimensional error, which is likely to cause malfunction. .

  In addition, even when the upper and lower rails are mounted in advance with the upper and lower rails attached in advance, the upper ends of the movable bars and the screen can be slidably assembled to the upper rails, even if there is no problem with the dimensional error in the building opening itself. Considering that the lower rail is not satisfactory in terms of strength, it is necessary to stably hang the movable rail etc. on the upper rail without applying a large force etc. to the lower rail. If the upper rail is attached to the opening of the building in advance, there is a difficulty in assembling the member that suspends the upper end of the screen or the movable rail in the suspended state through the lower opening of the upper rail. There is tremendous difficulty in developing a structure to stably suspend a suspended member and movable rail on the upper rail, and as a result, the screen and movable rail are suspended from the lower opening of the upper rail. It should say that improper design to to.

  However, if the lower rail, which has a problem of strength for barrier-free, bears the weight of the screen, movable rail, etc., the same reference numerals are assigned to the parts corresponding to those in the embodiment of the present invention. As shown in Fig. 2), the lower rail 14 hangs down due to the weight of the screen 18 and the movable rail 15 at each stage of manufacturing, storing and transferring the horizontal roll screen device. Consideration for suppressing the above is required, and the workability at each stage of manufacturing, storage, transfer and the like is greatly affected.

  On the other hand, the barrier-free horizontal screen device is intended to prevent the installation from becoming an obstacle to traffic when a person who has difficulty in walking passes, and travels on the lower rail as described above. Since the slide rail is configured to be housed in the screen box or movable rail when the screen is wound, the passage size becomes narrow due to the increase in the size of the slide rail. When the necessity of disposing the screen device is reduced, it is often desired to remove the screen device itself even if it is a barrier-free type. For this reason, it is desired that a completely assembled screen device, in particular, a barrier-free type horizontal screen device, can be easily attached to a required position or can be temporarily removed.

  In order to solve the problems described above, the screen device itself is finally configured in a state where the components of the screen device are entirely assembled in the screen frame and fixed to the building opening frame. This configuration eliminates the need to absorb the dimensional error of the building opening frame when assembling the screen device, and at the same time allows it to be easily attached to the required position or temporarily However, when assembling other components of the screen device to the screen frame, a pair of left and right fixed frames and upper and lower rails constituting the screen frame are assembled in advance into a single frame shape. Rather than assembling each component, the screen and movable rail are separated with at least the lower rail that has a problem in strength separated. Seen with steps, and even after the assembly completion, it is necessary to employ a configurable to such assembly work as a force is not applied from the movable 桟等 on the bottom rail. After such assembly work, the components of the screen frame, including the lower rail, are assembled into a single frame so that the lower rail having a problem in strength can be installed in the opening of the building while being protected. It becomes possible.
