Description

  The present invention relates to a screen device mounting structure suitable for attaching a pre-framed horizontal screen device to a building opening via a mounting frame (frame).

  Conventionally, when a horizontal screen device is attached to a building opening, as shown in FIG. 1, an attachment frame (frame) 10 is assembled to the building opening, and four rounds are preliminarily framed in the attachment frame. The mounting structure for attaching the screen device 1 allows the screen device 1 to be stably fixed easily using a simple fixing bracket, and the subsequent maintenance with the removal of the screen device is also easy. Is commonly used.

  In the present invention as well, basically, a mounting structure common to some conventional products in FIG. 1 is used, but the problem of the mounting structure used conventionally, that is, the mounting frame assembled to the building opening. Due to the dimensional fit of 10 and the structure of the fixing bracket 25 used for fixing the screen device 1, the screen device cannot always be fixed easily and stably as described in detail below. These problems are fundamentally improved regardless of the construction conditions.

  9A to 11B, the problems of the conventional mounting structure of the screen device will be described. First, FIG. 9 shows the installation of the screen device 1 to the building opening. FIG. 10 shows a mounting state when the dimension between the inner surfaces in the height direction of the mounting frame 10 assembled to the opening of the building is larger than the standard dimension by d millimeters, and FIG. 10 shows the case where the dimension is the standard dimension. FIG. 11 shows a case where the same dimension is smaller than the standard dimension by d millimeters. (A) of each said figure is a principal part front view which shows the state which attached the upper frame 2 of the screen apparatus 1 to the upper board 11 of the attachment frame 10, (b) is the sectional side view.

  The screen device 1 in these drawings has a known configuration that enables a roll-shaped screen 7 wound around a winding shaft (not shown) to be stretched by horizontal pulling. Engagement grooves provided in the inner rail 8 pass through a plurality of engagement elements 7a attached along the upper end of the screen 7 through slits 9a provided on the lower surface side of the inner rail 8 inserted into the upper frame 2. 9 is locked. This screen 7 has one end attached to a movable bar 6 for opening and closing that is slidably suspended on the upper frame 2, and moves the movable bar 6 along the longitudinal direction of the upper frame 2. The screen 7 can be extended and wound.

  Further, since the upper frame 2 of the screen device 1 is attached to the upper plate 11 of the mounting frame 10 by a fixing bracket 25 described later, the rear surface of the upper frame 2 is along the longitudinal direction of the upper frame. A bolt engaging groove 20 is provided for slidably engaging the head 22a of the mounting bolt 22. The mounting bolt 22 having the head 22a engaged with the bolt engaging groove 20 is inserted into a vertically long mounting hole 25a in a fixing bracket 25 which is fixed to the upper plate 11 of the mounting frame 10 with a screw 24. The screen device 1 is fixed to the upper plate 11 of the mounting frame 10 by being fastened and fixed at 23.

When the screen device 1 is mounted, if the construction tolerance of the inner surface dimension in the height direction of the mounting frame 10 assembled to the building opening is ± d millimeters with respect to the standard dimension, FIGS. As can be seen from the above, the vertically long mounting hole 25a in the fixing bracket 25 must be capable of adjusting the tightening and fixing position of the nut 23 with respect to the mounting bolt 22 within a range of ± d millimeters.
Note that, as described above, when there is a construction allowance in the mounting frame 10, a gap is generated between the mounting frame 10 and the upper frame 2 of the screen device, so that it is sealed by the sealing material 26.

  When the screen device 1 is fixed to the mounting frame 10 by the above-described mounting structure, the inner size of the mounting frame 10 depends on the inner size of the building opening, and the screen device 1 installed therein has a mounting frame. In general, a size that fits inside 10 is selected. The screen device 1 is fixed in the mounting frame 10 by first placing the lower frame 5 of the screen device 1 on the lower plate 13 of the mounting frame 10 in the mounting frame 10. For example, as shown in FIG. 1, the side frames 3 and 4 of the screen device 1 are positioned relative to the angle 14 attached to the left and right side plates 12 of the mounting frame 10. , 4 are respectively bonded by a double-sided adhesive tape 12a or the like, and the screen device 1 is temporarily held so as not to move from the position.

  The final fixing of the screen device 1 to the mounting frame 10 includes at least fixing to prevent the lower frame 5 of the screen device 1 from shifting and the upper frame 2 of the screen device 1 to the upper plate 11 of the mounting frame 10. The fixing is performed securely, and as a result, the fixing of the screen device 1 is stabilized. In particular, when the upper frame 2 of the screen device 1 is fixed to the mounting frame 10, the screen device 1 itself tilts back and forth due to its own weight or the like when there is a problem and the fixing is not reliably performed. This is very important from a safety standpoint because it can cause problems.

  The most important point lies in the configuration of the fixing bracket 25, and the height of the mounting frame 10 in which the vertically long mounting holes 25a in the fixing bracket 25 are assembled to the building opening is particularly important in the configuration. Although it is convenient in terms of increasing the use range of the fixing bracket 25 if the dimension between the inner surfaces in the direction is increased according to the construction allowance, if the dimension between the inner surfaces is shorter than the standard dimension, 11 (a) and 11 (b), the lower end of the fixing bracket protrudes below the upper frame 2 of the screen device 1, and not only the appearance from the indoor side deteriorates, but also the movable rail If the hand is put out to a position along the upper frame 2 when the screen 7 is opened and closed by 6, the hand may be damaged.

  From this point of view, it is not always desirable from the viewpoint of safety and other aspects to consider the handling tolerance of the dimension between the inner surfaces in the height direction of the mounting frame 10 by the vertically long mounting holes 25a of the fixing bracket 25. Needless to say, there is a demand for a fixing bracket that is sufficiently compliant with the construction allowance of the mounting frame 10 and has no unsightly appearance.

  The technical problem of the present invention is suitable for use in the case of attaching a pre-framed horizontal screen device to a building opening via a mounting frame (frame), and is sufficient for installation frame construction permission. It is an object of the present invention to provide an attachment structure for a screen device that is not unsightly in appearance and that is easy to construct and provides an excellent attachment state in terms of safety.

An arm having a mounting bolt insertion hole projecting from a bolt engaging groove in the upper frame of the screen device is pivotally attached to the lower surface. Attach the contact surface to the building opening. In the state where the screen device placed on the lower plate of the mounting frame is positioned at the installation position on the lower plate, the insertion of the arm tip in the fixing bracket is performed by the rotation at the pivotally attached portion of the arm. The screen device can be fixed to the mounting frame by moving and fitting to the position of the mounting bolt protruding from the bolt engaging groove of the upper frame, and screwing the nut into the mounting bolt to fix the arm tip. A screen device mounting structure is provided.

In a preferred embodiment of the screen device mounting structure according to the present invention, the axial position of the screw hole drilled in the corresponding contact surface for fixing the contact surface of the fixing bracket to the mounting frame is drilled in the hanging surface. It is configured to be formed by shifting in the horizontal direction with respect to the axis of the bolt hole to be provided.

FIG. 1 is a view for explaining a basic form of a structure for attaching a screen device to a building opening according to the present invention. Similar to the prior art, when attaching a horizontal screen device 1 to a building opening, A mounting structure is adopted in which a mounting frame (frame) 10 is assembled to the inside of the building opening, and the screen device 1 that is preliminarily framed on four sides is mounted in the mounting frame 10.
In the following description, the same reference numerals as those used in the description of the prior art are used for the respective constituent elements of the embodiment of the present invention, which are the same as or correspond to those in the prior art described above. This will be explained.

  The screen device 1 includes an upper frame 2 installed on an upper portion, one side frame 3, a winding box that rotatably accommodates a winding shaft around which a roll-shaped screen 7 is wound, and the other side. A frame 4 is constructed, and is installed between a receiving frame that receives the movable beam 6 when the screen 7 is rewound by operating the movable beam 6 attached to the tip of the screen 7 and the lower ends of the pair of side frames 3 and 4. The lower frame 5 is framed on four sides.

  2 to 4, a large number of engaging elements 7 a attached along the upper end of the screen 7 are slidably held in the upper frame 2, An inner rail 8 for sliding the screen 7 in the longitudinal direction of the upper frame is accommodated. The inner rail 8 has an engagement groove 9 provided in the inner rail 8 opened to the lower surface side by a slit 9a, and the engagement element 7a is slidably engaged in the inner rail 8 through the slit 9a. Although not shown, a similar inner rail may be provided in the lower frame 5 so that the engagement element attached along the lower end of the screen 7 can be slidably held.

  The movable bar 6 is slidably suspended from the upper frame 2, and the screen 7 has a leading end attached to the movable bar 6 from the take-up shaft. The screen 7 can be expanded or wound by being moved along the longitudinal direction of 2, and the screen 7 is automatically wound by accommodating a winding spring in the winding shaft. It can also be configured.

  Since the upper frame 2 of the screen device 1 is attached to the upper plate 11 of the mounting frame 10 by means of fixing brackets 28 as shown in FIGS. 1 and 2 to 4, the screen device 1. 1 is provided with a bolt engaging groove 20 having a narrowed opening for slidably engaging the head 22a of the mounting bolt 22 along the longitudinal direction of the upper frame 2. Provided. A mounting bolt 22 having its head engaged with the bolt engaging groove 20 is connected to a fixing bracket 28 fixed to the lower surface of the upper plate 11 of the mounting frame 10 with a screw 24 as described in detail below. Thereby, the upper frame 2 of the screen device 1 is fixed to the upper plate 11 of the mounting frame 10.

  The fixing bracket 28 for fixing the screen device 1 to the upper plate 11 of the mounting frame 10 is formed by bending a metal plate into an L shape so that the contact surface 30 to the upper plate 11 of the mounting frame 10 and the screen device 1 are fixed. An arm 33 is formed with a penetrating lower surface 31 in contact with the rear surface of the upper frame 2 and an insertion hole 34 at the tip for inserting the mounting bolt 22 protruding from the bolt engaging groove 20 in the upper frame 2 of the screen device 1. Is configured to be pivotally attached to the hanging surface 31. In this pivoting portion 32, it is desirable that the hanging surface 31 and the arm 33 are rotatably connected by eyelets or rivet-shaped metal fittings.

  When the screen device 1 is attached to the building opening via the attachment frame 10, prior to fixing the upper frame 2 of the screen device to the attachment frame 10 by the fixing bracket 28, FIG. As shown in FIG. 1, using the lower positioning metal fitting 40 as shown in FIG. 1C, the lower plate 13 of the mounting frame 10 and the lower frame 5 of the screen device 1 placed on the lower plate In addition to positioning, it is desirable to perform positioning by bonding the side frames 3 and 4 of the screen device to the angle 14 attached to the pair of side plates 12 of the mounting frame 10 with the double-sided adhesive tape 15.

  The lower positioning metal fitting 40 is formed by bending a metal plate into an L shape, and a standing surface 42 that contacts the lower surface 13 of the mounting frame 10 and the rear surface of the lower frame 5 of the screen device 1. An insertion hole 45 for inserting a mounting bolt 43 appropriately projected from the lower frame 5 side of the screen device 1 and fixing with a nut 44 is formed in the central portion on the standing surface 42. In order to avoid the presence of the nut 44 from becoming an obstacle to the fixing work by the screw 47, the screw hole is formed at a position shifted from the central axis of the mounting bolt 43. 46 are established.

  The lower part of the screen device 1 is fixed by the lower positioning metal fittings 40 in comparison with the fixing of the upper frame 2 of the screen device 1 to the mounting frame 10 by the fixing metal members 28. Not only does it not always float closely, but the weight of the screen device 1 acts on the lower plate 13, so that the configuration of the positioning fitting 40 itself can be made very simple.

  Further, the above-described attachment of the lower frame and side frame of the screen device 1 to the mounting frame 10 is not a part where they receive a particularly large force after the screen device is installed. When the lower frame 5 of the device 1 is formed of a thin plate, the lower ends of the left and right side frames 3, 4 of the screen device 1 are securely fixed to the lower plate 13 of the mounting frame 10, thereby It can replace with use of the positioning metal fitting 40.

  After positioning the lower portion of the screen device 1 with respect to the mounting frame 10 described above, the upper frame 2 of the screen device 1 placed on the lower plate 13 is fixed by the fixing bracket 28. In a state where the lower frame 5 of the screen device 1 is positioned at the installation position on the lower plate 13, the insertion hole 34 at the tip of the arm 33 that attaches the fixing bracket 28 to the hanging surface 31 is provided with the mounting bolt. The contact surface 30 is fixed to the lower surface of the upper plate 11 of the mounting frame 10 with screws 24 so that the base portion 22 can be fitted, and then the arm 33 of the fixture 28 is fixed. The insertion hole 34 at the tip of the arm 33 is brought to the position of the mounting bolt 22 by the rotation at the pivoting portion 32 and the position adjustment of the mounting bolt 22 in the bolt engaging groove 20 of the upper frame 2. Fitted by moving the nut 35 by screwing the mounting bolt 22, so as to secure the screen apparatus 1 to the mounting frame 10.

  According to this configuration, when the screen device 1 is mounted, the construction allowance of the dimension between the inner surfaces in the height direction of the mounting frame 10 assembled in the opening of the building is allowed to be set in the insertion hole 34 at the tip of the arm by the rotation of the arm 33. Compared to the vertically long mounting hole 25a in the conventional fixing bracket 25 as described above with reference to FIGS. 9 to 11, it can sufficiently cope with the construction tolerance of the mounting frame 10. In addition, there is no place that is unsightly in appearance, and it is possible to obtain a mounting state that is easy to construct and excellent in safety.

  In particular, the mounting structure of the screen device 1 does not require the fixing bracket 28 for fixing the upper portion of the screen device 1 to support the weight of the screen device 1. By connecting the arm 33, the structure for supporting the construction of the mounting frame 10 that supports the screen device 1 can be configured to be compact and have a large corresponding range, thereby preventing the screen device 1 from tilting in the front-rear direction. It is very effective in that it can be supported stably.

  Further, the fixing bracket 28 of the screen device 1 is the same as the positioning bracket 40 described above with reference to FIG. 6 and the like. However, as clearly shown in FIG. The position of is shifted. That is, the axial position of the screw hole 36 drilled in the corresponding contact surface 30 to fix the abutting surface 30 of the fixing bracket 28 to the mounting frame 10 with respect to the pivoting portion 32 of the arm 33 on the hanging surface 31. The bolt engaging groove 20 is formed by shifting in the longitudinal direction. This takes into account the use of a decorative nut as the nut 35 used for fixing the upper frame 2 on the back surface of the upper frame 2 of the screen device 1.

  7 and 8 show the main part of a second embodiment of the screen device mounting structure according to the present invention. The fixing bracket 29 used in the second embodiment is the same as the fixing bracket 28 in the first embodiment described above, which is suitable when the opening of the building opening is wide. A long member corresponding to the contact surface 30 and the hanging surface 31 of the first embodiment, which can be attached to the upper plate 11, is provided with a plurality of arms 33 for attaching to a plurality of positions of the upper frame 2 of the screen device 1. It is configured as a provision.

  The fixing bracket 29 of the second embodiment shown in FIG. 8 shows a mounting manner when the mounting frame 10 is standardly constructed, and has a length necessary for mounting the arms 33 at a plurality of positions on the hanging surface 31 respectively. As described above, a plurality of arms 33 are pivotally attached to the hanging surface 31. Of course, the required number of mounting bolts 22 need to be engaged with the bolt engaging grooves 20 in accordance with the number of arms 33. Further, if the contact surface 30 and the hanging surface 31 are made as long as the upper frame 2 of the mounting frame 10, the gap used when a gap is generated between the upper frame 2 and the mounting frame 10 of the screen device 1. The material 26 can be omitted.

  The fixing bracket 29 is different from the case of FIG. 3 except that the contact surface 30 and the hanging surface 31 are long and a plurality of arms 33 are pivotally attached to the hanging surface 31. Since there is no place, the same reference numerals are given to the same or corresponding parts as those in FIG. 3, and the description thereof is omitted.
