Description

The present invention relates to a blind installation device.

A conventional blind installation device is shown in Japanese Utility Model Application Publication No. 62-176399 (Patent Document 1). The blind installation device disclosed in this document fixes the blind to the installation target such as a window frame, wall, or ceiling surface via a mounting metal fitting (bracket) and auxiliary metal fittings.

This has the effect of making it possible to support and fix the blinds in an appropriate position by using auxiliary fittings, even in cases where the mounting fittings (brackets) cannot be attached to the mounting object or the mounting object's position causes the blinds to shift in the forward/backward or upward/downward direction.

Japanese Utility Model Application Publication No. 62-176399

However, in conventional blind installation devices such as those in Patent Document 1, when the operating device is provided on the side edge of the blind, if the position of the installation target is far from the side edge of the blind, there is a problem in that the mounting bracket cannot be supported and fixed at an appropriate position on the blind.

The present invention was made in consideration of these problems, and its purpose is to provide a blind mounting device that can support and fix the mounting hardware (bracket) at an appropriate position on the blind, even if the mounting position is away from the side edge of the blind.

To solve the above problems, the present invention provides a blind installation device capable of fixing a blind support member that suspends a shielding material in an openable and closable manner to an object to be installed, the blind installation device comprising: a long base member that can be fixed to the object to be installed; a bracket that can support the blind support member; and a restricting member that restricts the position of the blind support member in the front-rear or left-right direction, the bracket and the restricting member being fixed to the base member at positions spaced apart in the long direction of the base member.

With this configuration, the bracket only needs to be located at a position separated from the restricting member in the longitudinal direction of the base member, and there is no need to fix the location. Therefore, even if the position of the mounting object is away from the side end of the blind, the bracket (mounting hardware) can be fixed at any position on the base member, so the bracket can be supported and fixed at an appropriate position on the blind.

The present invention can be applied in a variety of ways. For example, the regulating member may be a spacer member that abuts or engages with the blind support member so that the blind support member is aligned (corrected) parallel to the base member or in the same straight line as other adjacent blind support members. The spacer member allows the blind to be attached to the mounting object without shifting in the forward/backward direction, allowing it to be installed in an accurate position.

The restricting member may also be a second bracket capable of supporting the blind support member. When two blinds are connected together, one blind can be supported by the bracket and the other blind can be supported by the second bracket. Thus, the distance between the two blinds can be narrowed by arranging the bracket and the second bracket.

A gap may be provided between the base member and the mounting object to accommodate a fixing member for fixing the bracket. This improves the design as the fixing member is not exposed from the base member.

According to a second aspect of the present invention, there is provided a blind installation device capable of fixing a blind support member for suspending a shielding material in an openable and closable manner to an installation target, the blind installation device comprising: a long base member that can be fixed to the installation target; and a bracket that can support the blind support member, the base member being attached to the installation target along the longitudinal direction of the support member; a gap that can accommodate a fixing member for fixing the bracket to the base member being provided between the base member and the installation target; and the bracket being fixed to the base member in the longitudinal direction closer to the end than the installation position to the installation target.

With this configuration, even if the base member is positioned along the longitudinal direction of the support member in contact with the attachment target over its entire length, the fixing member is provided in the accommodation space between the base member and the attachment target, so the bracket can be fixed closer to the end of the base member than the attachment position of the base member to the attachment target, and the bracket can be supported and fixed at an appropriate position on the blind.

The base member may also be provided with a plurality of attachment sections in the longitudinal direction so that it can be attached to the attachment target. The attachment section can be selected according to the position of the attachment target, and the base member can be fixed to the attachment target via the attachment sections.

The bracket may be fixed to the base member so as to be able to support the blind support member near the end in the longitudinal direction. Since the bracket can be fixed near the end of the blind support member, it is possible to prevent the blind support member from bending when a chain or operating cord is pulled as an operating part for the blind.

The blind mounting device of the present invention can support and fix the mounting bracket at an appropriate position on the blind, even if the mounting position is away from the side edge of the blind. Other advantages of the present invention will be explained in the description of the embodiment of the invention below.

A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. Note that in this specification and drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

First Embodiment
The overall configuration of the blind mounting device 100 and the roller screen 200 of this embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a front view showing the overall configuration of the blind mounting device 100 of this embodiment and the roller screen 200 mounted on the blind mounting device 100, and Fig. 2 is a partial cross-sectional view of the vicinity of the bracket as viewed from the front. A general roller screen 200 is used in this embodiment. First, each component of the roller screen 200 mounted on the blind mounting device 100 of this embodiment will be described.

The screen 210 is used to open and close openings such as windows, and to partition indoor spaces. As shown in FIG. 1, the upper end of the screen 210 is connected to the winding pipe 230, and the screen 210 is suspended from the winding pipe 230 so that it can be wound up and unwound. A weight bar 240 that applies tension to the screen 210 is disposed at the lower end of the screen 210.

The blind support member 220 is composed of a set frame 222 that is fixed to a window frame or the like via a bracket 120, and side plates 224 that are provided at both ends of the set frame 222 and rotatably support the winding pipe 230. The blind support member 220 is supported by the bracket 120 as shown by the arrow a in Figure 1.

A pulley 250 is provided at one end of the winding pipe 230, which can rotate together with the winding pipe 230 and is disposed between the winding pipe 230 and the side plate 224. An operating chain 252 is wound around the pulley 250, and the rotation of the pulley 250 is controlled by pulling the operating chain 252.

The above describes the configuration of the roller blind 200. Next, the blind installation device 100, which is a feature of this embodiment, will be described with reference to FIG. 1, FIG. 2, and FIG. 3. The blind installation device 100 is capable of fixing the blind support member 220, which suspends the screen (shielding material) 210 in an openable and closable manner, to the installation target FT. The installation target FT is a base to which a ceiling board material CB such as a plaster board is fixed. As shown in FIG. 1 and FIG. 2, the blind installation device 100 is configured to include a long base member 110 that can be fixed to the installation target FT, a bracket 120 that is fixed to one position of the base member 110 and can support the blind support member 220 at a position spaced apart from the installation target FT in the blind left-right direction, and a spacer member (regulating member) 130 that is fixed to another position of the base member 110 and regulates the movement of the blind support member 220.

(Base member 110)
The base member 110 is for disposing the bracket 120 at any position on the blind support member 220 regardless of the position of the attachment target FT. The base member 110 is an elongated member that can be fixed to the attachment target FT and extends in the longitudinal direction of the set frame 222, as shown in Figures 1 and 2 .

As shown in FIG. 3, the base member 110 is formed with a concave cross section over its entire length in the longitudinal direction, and has an insertion hole (mounting portion) 110a formed at the bottom through which a screw 112 is inserted to screw the base member 110 to the mounting target FT. There are five insertion holes 110a in the longitudinal direction, each pair consisting of two holes arranged side by side in the short direction of the base member 110. The insertion holes 110a are elongated holes extending in the longitudinal direction of the base member 110, allowing the base member 110 to move slightly relative to the screw 112.

In this embodiment, the base member 110 has a cross-sectionally concave shape over its entire length in the longitudinal direction, but only the portion where the bracket 120 is fixed may have a cross-sectionally concave shape to accommodate the nut 122 and screw 124 described below. In this embodiment, five insertion holes 110a are provided in the longitudinal direction of the base member 110, and the shape of the insertion holes 110a is an elongated hole, but the number and shape of the insertion holes 110a can be designed as desired.

The bracket 120 is fixed to one end of the base member 110, and the spacer member 130 is fixed to the other end. As shown in FIG. 2, the base member 110 is placed in contact with the ceiling board material CB over its entire length with the bracket 120 and the spacer member 130 facing downward, and is fixed to the mounting target FT with screws 112 through the insertion holes 110a at any position. The roller blind 200 is operated by the operating chain 252 attached to the end of the winding pipe 230, so a force is applied to the end of the set frame 222 in a downward direction. Therefore, it is preferable to support the end of the set frame 222 with the bracket 120. For this reason, the base member 110 is placed so that the bracket 120 supports the end of the set frame.

(Bracket 120)
The bracket 120 supports the set frame 222. A typical bracket 120 is used. As shown in Fig. 3, the bracket 120 is disposed on the lower surface of one end of the base member 110 and fixed by a screw 124 via a nut 122 disposed on the upper surface.

(Spacer Member 130)
The spacer member 130 regulates the position of the blind support member 220 in the front-rear or left-right direction. As shown in Fig. 3, the spacer member 130 is configured in a rectangular shape, and is fixed to the underside of the other end of the base member 110 by welding, adhesive, or the like. The spacer member 130 fits into the inside of the set frame 222 to position the blind support member 220 and prevent it from shifting out of position. The spacer member 130 can be made of any material, and may be made of rubber sponge, for example.

The spacer member 130 may be configured to be slightly smaller so that a slight gap is formed between it and the inside of the set frame 222. This configuration makes it easier to insert the spacer member 130 into the set frame 222 while preventing significant misalignment of the blind support member 220. The spacer member 130 may also be configured to be slightly larger than the inside of the set frame 222 and made of an elastically deformable material. This configuration allows the spacer member 130 to elastically deform and adhere closely to the inside of the set frame 222, preventing misalignment.

The configuration of the blind mounting device 100 of this embodiment has been described above. Next, the process of mounting the roller blind 200 to the blind mounting device 100 will be described with reference to Figure 4. Figure 4 is a cross-sectional view of the vicinity of the bracket as viewed from the side.

When mounting the roller blind 200 to the blind mounting device 100, as shown in FIG. 4(a), the bracket 120 and the spacer member 130 are placed face to face with the set frame 222, the front flange of the set frame 222 is hooked to the locking portion of the bracket 120, and then the rear side of the set frame 222 is raised as shown by the arrow b. Then, as shown in FIG. 4(b), the spacer member 130 is inserted into the set frame 222 to position the set frame 222. As the spacer member 130 is inserted into the set frame 222, the roller blind 200 is positioned parallel to the base member 110. The set frame 222 is then raised to support the set frame 222 with the bracket 120.

Next, the installation state of the blind installation device 100 depending on the position of the installation target FT will be described with reference to Figure 5. Figure 5 is a front view for explaining the installation of the base member 110 depending on the position of the installation target FT.

When the mounting target FT is located near both ends of the set frame 222, as shown in FIG. 5(a), it is fixed to the mounting target FT by the screw 112 through the insertion hole 110a near the bracket 120 of the base member 110.

When the mounting target FT is positioned toward the center of the set frame 222, as shown in FIG. 5(b), the mounting target FT is fixed to the mounting target FT by the screw 112 through the insertion hole 110a near the spacer member 130 of the base member 110.

(Effects of the First Embodiment)
As described above, according to this embodiment, the bracket 120 only needs to be provided at a position spaced apart from the spacer member 130 in the longitudinal direction of the base member 110, and there is no need to fix the position at which it is provided. Therefore, even if the position of the attachment target FT is away from the side end of the roller blind 200, the bracket 120 can be fixed at any position on the base member 110, so that the bracket 120 can be supported and fixed at an appropriate position on the roller blind 200.

In addition, the spacer member 130 allows the roller blind 200 to be fixed to the mounting target FT without shifting in the forward/rearward direction, allowing for accurate installation.

The gap SP between the base member 110 and the mounting target FT can accommodate the nuts 122 and screws 124 for fixing the bracket 120, so the nuts 122 and screws 124 are not exposed from the base member 110. This improves the design.

Even if the base member 110 is positioned in contact with the mounting target FT over its entire length, the nuts 122 and screws 124 are provided in the gap SP between the base member 110 and the mounting target FT, so that the bracket 120 can be fixed closer to the end of the base member 110 than the mounting position of the base member 110 to the mounting target FT, and therefore the bracket 120 can be supported and fixed at an appropriate position on the roller blind 200.

The insertion hole 110a can be selected to match the position of the mounting target FT, and the base member 110 can be attached to the mounting target FT via the insertion hole 110a.

The bracket 120 can be fixed near the end of the blind support member 220, which prevents the blind support member 220 from bending when the operating chain 252 of the roller blind 200 is pulled.

Second Embodiment
The blind mounting device 300 according to this embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram showing the blind mounting device 300 according to this embodiment. In this embodiment, the configuration of the blind mounting device 300 is used when roll screens 400-1, 400-2 are mounted in series, and differs from the first embodiment in that a second bracket 340 is provided instead of the spacer member 130 of the first embodiment. The present embodiment will be described mainly with respect to the differences from the first embodiment.

The bracket 320 and roller blinds 400-1 and 400-2 of this embodiment can be made to correspond to the bracket 120 and roller blind 200 of the first embodiment, so a description thereof will be omitted.

The base member 310 differs from the base member 110 of the first embodiment in the shape of the insertion holes 310a through which the screws 312 for screwing the base member 310 to the mounting target FT are inserted, and in that fixing holes 310b for fixing the bracket 320 and the second bracket 340 are provided.

As shown in FIG. 6, the base member 310 is formed with a concave cross section similar to the base member 110 of the first embodiment. The through hole 310a formed in the bottom is circular. The positions and number of the through holes 310a are similar to those of the base member 110 of the first embodiment. The fixing hole 310b is formed adjacent to the through hole 310a in the short direction of the base member 310. The fixing hole 310b is an elongated hole extending in the short direction of the base member 110, and allows the position adjustment of the bracket 320 and the second bracket 340 in the short direction of the base member 110. The through hole 310a and the fixing hole 310b formed in the base member 310 may be shaped similarly to the holes formed in the bracket 320 and the second bracket 340.

As shown in FIG. 6(a), the bracket 320 is fixed to one end of the base member 310, and the second bracket 340 is fixed to the other end. The bracket 320 and the second bracket 340 have the same configuration in this embodiment, but may have different configurations. The bracket 320 and the second bracket 340 are fixed to any of the five fixing holes 310b with nuts 322, 342 and screws 324, 344, similar to the bracket 120 in the first embodiment. At this time, the screw holes 322a, 342a of the nuts 322, 342 are arranged so that they overlap with the fixing holes 310b, and are screwed in place with the screws 324, 344. In this embodiment, they are fixed via the fixing holes 310b at both ends.

The configuration of the blind mounting device 300 has been described above. Next, the process of mounting two roller screens 400-1 and 400-2 in series on the blind mounting device 300 will be described with reference to Figure 7. Figure 7 is a partial cross-sectional view of the blind mounting device 300 with two roller screens 400-1 and 400-2 mounted thereon, viewed from the front.

As shown in FIG. 7, the base member 310 is fixed to the mounting target FT by the screw 312 via the insertion hole 310a and the fixing hole 310b in the center of the longitudinal direction. At this time, the nuts 322, 342 and the screws 324, 344 are placed in the gap SP between the base member 310 and the ceiling board material CB. The bracket 320 and the second bracket 340 are attached closer to the center of the longitudinal direction than both ends of the base member 310. The bracket 320 supports the vicinity of the left end of the set frame 422-1 of one of the roller screens 400-1. The second bracket 340 supports the vicinity of the right end of the set frame 422-2 of the other roller screen 400-2.

Next, the installation state of the blind installation device 300 according to the position of the installation target FT will be described with reference to Figure 8. Figure 8 is a front view for explaining the installation of the base member 310 according to the position of the installation target FT.

When two roller blinds 400-1, 400-2 are connected together, as shown in FIG. 8, the blind mounting device 300 for connected blinds of this embodiment is placed in the center of the mounting space such as a window frame, and bracket mounting devices similar to the bracket mounting device 100 of the first embodiment are placed near both ends.

As shown in FIG. 8(a), the installation state of the blind installation device 300 is described when three installation targets FT are arranged at equal intervals near both ends and in the center of the installation space such as a window frame. The blind installation device 300 to be installed on the central installation target FT has the base member 310 attached to the installation target FT by the screw 312 via the insertion hole 310a and the fixing hole 310b in the center of the longitudinal direction.

Next, as shown in FIG. 8(b), the mounting state of the blind mounting device 300 will be described when three mounting targets FT are located near both ends of a mounting space such as a window frame and close to one of the mounting targets FT. The blind mounting device 300 mounted to the central mounting target FT is fixed to the mounting target FT by a screw 312 via the insertion hole 310a and the fixing hole 310b close to the second bracket 340 of the base member 310. In this way, the positions of the bracket 320 and the second bracket 340 can be adapted to the position of the mounting target FT without changing them from the case of FIG. 8(a).

(Effects of the Second Embodiment)
As described above, according to this embodiment, when two roll screens 400-1, 400-2 are connected together, one roll screen 400-1 can be supported by the bracket 320, and the other roll screen 400-2 can be supported by the second bracket 340. Therefore, the arrangement of the bracket 320 and the second bracket 340 can narrow the distance between the two roll screens 400-1, 400-2.

Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an example. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention.

For example, in the first embodiment described above, a gap SP capable of accommodating nuts 122 and screws 124 for fixing the bracket 120 is provided between the base member 110 and the mounting target FT, but the present invention is not limited to this example. Any design can be used, even if the mounting target is located away from the side end of the blind, as long as the bracket can be supported and fixed at an appropriate position on the blind. For example, the base member 110 may be flat and attached to the mounting target without forming a gap.

In addition, in the above embodiment, the base member 110 has multiple insertion holes 110a in the longitudinal direction to enable attachment to the attachment target FT, but the present invention is not limited to this example. Even if the attachment target is located away from the side end of the blind, any design can be used as long as the bracket can be supported and fixed at an appropriate position on the blind. For example, multiple hooks can be provided in the longitudinal direction of the base member 110 to connect the brackets.

In addition, in the first embodiment described above, the bracket 120 is configured to be fixed to the base member 110 so as to be able to support the blind support member 220 near the end in the longitudinal direction, but the present invention is not limited to this example and can be designed as desired.

The embodiments, modifications, and applications described above can be implemented in any suitable combination.
