Description

[Technical Field]

[0001] The present invention relates to a support device for blinds. [Background technology]

[0002] A conventional blind support device is disclosed in Japanese Patent Laid-Open Publication No. 9-119276 (Patent Document 1). The blind support device disclosed in Patent Document 1 is used for a roller blind and includes a flange-shaped fall prevention fitting attached to the shaft portion of the winding pipe, and a connecting wire stretched between the fall prevention fitting and a bearing bracket that supports the shaft portion of the winding pipe.

[0003] With this configuration, even if the shaft of the take-up pipe comes off the bearing bracket during installation, the take-up pipe can be supported so that it does not fall. Also, even if the shaft of the take-up pipe comes off the bearing bracket due to improper installation, the take-up pipe can be prevented from falling. In other words, safety can be improved in case of an emergency. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-119276 Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the blind support device has a structure in which the bearing bracket and fall prevention fitting are connected by a connecting wire, it can only be applied to roller blinds. Therefore, there is a need for a blind support device that can be applied to different types of blinds, not just roller blinds.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to provide a blind support device that can be applied to different types of blinds. [Means for solving the problem]

[0007] In order to solve the above problems, according to the present invention, there is provided a blind support device comprising: a bracket fixed to a fixed surface; a support member for a blind supported by the bracket; and a connecting member connecting the bracket and the support member, wherein the support member has an engaging portion formed along its longitudinal direction, and the connecting member has an engaging portion that can be engaged at any position on the engaging portion, and the connection between the support member and the bracket by the connecting member can be maintained even when the support member is in an unsupported state where it is not supported by the bracket.

[0008] With this configuration, the brackets and support members are connected by the connecting member, making it possible to realize a blind support device that can be used for different types of blinds. In particular, this is advantageous in that even if the mounting position of the bracket relative to the support member differs depending on the type and size of the blind, the connecting position of the connecting member relative to the support member can be adjusted to match that position.

[0009] The present invention has various applications. For example, the connecting member may be a cord. This configuration allows the connecting member to be connected to the support member with good workability. Furthermore, by adjusting the length of the cord, the amount of sagging from the support member can be reduced. This improves the design and reduces interference with other components of the blind.

[0010] The engaging portion may be a plurality of holes formed along the longitudinal direction of the support member, and the engaging portion may be selectively engaged with the plurality of holes. With this configuration, the connecting position of the connecting member relative to the support member can be appropriately selected.

[0011] The engaging portion may be a groove formed continuously along the longitudinal direction of the support member, and the engaging portion may be capable of engaging with the groove. This configuration increases the degree of freedom in the connection position of the connecting member to the support member. Furthermore, the connection position can be finely adjusted while the connecting member is connected to the support member.

[0012] The engaging portion may also serve as a groove for attaching a component of the blind. With this configuration, an existing support member can be reused.

[0013] The locking portion may be a connector that can be locked to the locked portion by being inserted into the locked portion, and may have an easy-to-insert portion that makes it easy to insert into the locked portion, and a restricting portion that restricts removal from the locked portion after being inserted into the locked portion. With this configuration, the connecting member can be connected from the short side direction of the support member, making it easier to connect the connecting member to the support member. Furthermore, since the connecting member is easy to insert and is restricted from removing, it is easy to work with.

[0014] The connecting member may further include a bracket-side locking portion that is identical to the locking portion, and the bracket-side locking portion may be capable of locking to the bracket. With this configuration, the connecting member can be connected to both the bracket and the support member without distinguishing between the locking portion and the bracket-side locking portion.

[0015] The locking portion may be formed on the rear side of the shielding material suspended from the support member. With this configuration, the connecting member is connected to the support member on the rear side of the shielding material, thereby preventing the design of the front side of the blind from being impaired. [Effects of the Invention]

[0016] The blind support device of the present invention can be applied to different types of blinds. Other effects of the present invention will be described in the detailed description of the invention below. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant explanations will be omitted.

[0019] (First embodiment) A blind support device 100 according to a first embodiment will be described. First, the overall configuration of the blind 10 will be described with reference to Fig. 1. Fig. 1 shows the overall configuration of the blind 10 to which the blind support device 100 of this embodiment is applied, with (a) being a perspective view seen from the front and (b) being a perspective view seen from the back.

[0020] 1, the blind 10 of this embodiment comprises a blind support device 100 which includes a bracket 110 which is fixed to a fixed surface such as a ceiling, a window frame, or a wall, a head box 120 (support member) of the blind 10 which is supported by the bracket 110, and a connecting member 130 which connects the bracket 110 and the head box 120. Details of the blind support device 100 will be described later.

[0021] The blind 10 also has ladder cords 11 hanging down from a head box 120, and slats 12 are supported in an aligned state by the ladder cords 11. The lower ends of the ladder cords 11 are connected to a bottom rail 13 disposed below the slats 12. A lifting / lowering cord 14 for raising and lowering the slats 12 extends from the head box 120. One end of the lifting / lowering cord 14 passes through the slats 12 and is connected to the bottom rail 13.

[0022] An operating rod 15 is provided at one end of the head box 120 for tilting the ladder cord 11 to rotate the slats 12. The other end of the lifting / lowering cord 14, which is guided longitudinally within the head box 120, is inserted into the operating rod 15 and led out from the lower end of the operating rod 15. The slats 12 are raised and lowered by operating the other end of the lifting / lowering cord 14 up and down.

[0023] The overall configuration of the blind 10 has been described above. Below, the blind support device 100, which is a characteristic configuration of this embodiment, will be described with reference to Fig. 2 in addition to Fig. 1. Fig. 2 shows the configuration of the blind support device 100, where (a) is an exploded perspective view and (b) is a perspective view showing the connected state.

[0024] 2, the blind support device 100 comprises a bracket 110 fixed to a fixed surface, a head box 120 of the blind 10 supported by the bracket 110, and a connecting member 130 connecting the bracket 110 and the head box 120. The head box 120 has a plurality of head box side holes 121 (engaged portions) formed along its longitudinal direction, and the connecting member 130 has connectors 132 (engaging portions) that can be inserted into and engaged with the head box side holes 121, so that the connection between the head box 120 and the bracket 110 can be maintained even when the head box 120 is not supported by the bracket 110 and is in an unsupported state.

[0025] (Bracket 110) The bracket 110 is fixed to a fixed surface such as a ceiling, a window frame, or a wall surface to support the head box 120. As shown in FIG. 1, the bracket 110 is provided near both longitudinal ends of the head box 120. As shown in FIG. 2, the bracket 110 is configured in a substantially L-shape with a horizontal piece 111 and a vertical piece 112. In this embodiment, the fixed surface is a ceiling or a wall surface, and the horizontal piece 111 of the bracket 110 is fixed to the fixed surface.

[0026] 2, the bracket 110 has a bracket side hole portion 113 in the vertical piece 112 that can lock a connector 132 (locking portion) of a connecting member 130 (described later). The bracket side hole portion 113 may be a hole formed in the vertical piece 112 for inserting a screw to fix the bracket 110 to a fixing surface of a wall, or may be a hole provided separately for connecting the connecting member 130.

[0027] (Headbox 120) As described above, the head box 120 is where the mechanisms for raising, lowering, and rotating the slats 12 are located. As shown in FIG. 1 , the head box 120 is configured in a long, box-like shape, and has multiple head box side holes 121 formed along the longitudinal direction on its back surface. The head box side holes 121 have the same shape as the bracket side holes 113 and can engage connectors 132 of the connecting member 130, which will be described later. The mounting positions and number of brackets 110 relative to the head box 120 vary depending on the type of device (including various blinds, such as horizontal blinds like the blinds 10, vertical blinds, and pleated screens) and size. Therefore, by forming multiple head box side holes 121 along the longitudinal direction, it is possible to select a head box side hole 121 from the multiple head box side holes 121 that corresponds to the mounting position of the bracket 110. Furthermore, the mounting position of the bracket 110 relative to the head box 120 may vary depending on the conditions at the construction site. In this case, similarly to the above, it is possible to select the head box side hole portion 121 that corresponds to the mounting position of the bracket 110.

[0028] (Connecting member 130) The connecting member 130 connects the bracket 110 and the head box 120. As shown in Fig. 1, one end of the connecting member 130 is connected to the bracket 110 and the other end is connected to the head box 120. As shown in Fig. 2, the connecting member 130 is configured to include a long cord 131 and connectors 132-1 and 132-2 provided on both ends of the cord 131. The connectors 132-1 and 132-2 can be engaged with the bracket side hole 113 and the head box side hole 121, respectively.

[0029] As shown in Fig. 2, the connectors 132-1 and 132-2 are configured to have the same shape. Because the connectors 132-1 and 132-2 have the same shape, when there is no need to distinguish between them, they are referred to as connector 132. As shown in the enlarged view A of Fig. 2(a), the connector 132 has an easy-to-insert portion 132a that makes it easy to insert into the bracket side hole 113 or the head box side hole 121. The easy-to-insert portion 132a has a shape obtained by dividing a substantially truncated cone, whose diameter decreases toward the tip, into four equal parts in the circumferential direction, and dividing the part into four blocks that are spaced apart from each other.

[0030] The tip surface of the easy insertion portion 132a has a smaller diameter than the bracket side hole 113 and the head box side hole 121, making it easier to insert. On the other hand, the bottom surface of the easy insertion portion 132a has a larger diameter than the bracket side hole 113 and the head box side hole 121, and comes into contact with the bracket 110 and the head box 120, forming a restricting portion 132b that restricts the connector 132 from falling out from them. The easy insertion portion 132a is elastically deformable, and the bottom surface side also elastically deforms during insertion, allowing it to pass through the bracket side hole 113 and the head box side hole 121.

[0031] The configuration of the blind support device 100 has been described above. The procedure for installing the blind support device 100 will now be described with reference to Figures 3 and 4. Figure 3 is a diagram showing the state before the bracket 110 and the head box 120 are connected by the connecting member 130. Figure 4 is a diagram showing the state after the bracket 110 and the head box 120 have been connected by the connecting member 130.

[0032] Step 1: Attach the connecting member 130 to the bracket 110. 3, the connector 132-1 of the connecting member 130 is inserted into the bracket side hole 113 from the surface of the bracket 110 facing the head box 120, with the easy-to-insert portion 132a inserted into the bracket side hole 113, and the restricting portion 132b is engaged. This operation can be performed either before or after the head box 120 is attached to the bracket 110.

[0033] Step 2: Attach the connecting member 130 to the head box 120 supported by the bracket 110. As shown in Fig. 4, the easy-to-insert portion 132a of the connector 132-2 is inserted into any one of the head box side holes 121 of the head box 120, and the restricting portion 132b is engaged. Thus, the bracket 110 and the head box 120 are connected. Since a plurality of head box side holes 121 are formed in the longitudinal direction of the head box 120, as shown in Fig. 4(b), the position of the head box side hole 121 to be connected can be determined while adjusting the sagging of the cord 131 of the connecting member 130. Furthermore, regardless of the mounting position of the bracket 110 relative to the head box 120, the connector 132-2 can be engaged with the head box side hole 121.

[0034] The method of attaching the connecting member 130 to the bracket 110 and the head box 120 is not limited to the above method. That is, the head box 120 to which the connecting member 130 has been connected in advance may be supported by the bracket 110. In this way, even if the head box 120 accidentally falls out of the hands during the work of attaching the head box 120 to the bracket 110, the head box 120 can be prevented from falling because the bracket 110 and the head box 120 are connected by the connecting member 130.

[0035] The above has described the procedure for installing the blind support device 100. Below, the operation of the blind support device 100 will be described with reference to Figure 5. Figure 5 is a side view for explaining the state in which the head box 120 is supported by the connecting member 130, where (a) shows the state in which the head box 120 is supported by the bracket 110, and (b) shows the state in which the head box 120 is supported by the connecting member 130.

[0036] As shown in Figure 5(a), the head box 120 is supported by the bracket 110 and is further connected to the bracket 110 by a connecting member 130. In the unlikely event that the head box 120 is not properly attached to the bracket 110 due to poor installation (the hooks provided on the bracket 110 for locking the head box 120 are not sufficiently engaged), as shown in Figure 5(b), the head box 120 may come off the bracket 110 while the blinds 10 are being operated. Even in such a case, the head box 120 and bracket 110 are connected by the connecting member 130, preventing the head box 120 from falling.

[0037] (Effects of the first embodiment) As described above, according to this embodiment, the bracket 110 and the head box 120 are connected by the connecting member 130, making it possible to realize a blind support device 100 that can be used with different types of blinds. In particular, this is advantageous in that even if the mounting position of the bracket 110 relative to the head box 120 varies depending on the type and size of the blind, the connection position of the connecting member 130 relative to the head box 120 can be adjusted to match that position.

[0038] Furthermore, since the long cord 131 is used for the connecting member 130, the connecting member 130 can be connected to the head box 120 with good workability.

[0039] Furthermore, the engaging portion is a plurality of head box side hole portions 121 formed along the longitudinal direction, and the engaging portion is a connector 132 that can be selectively engaged with the plurality of head box side hole portions 121, so that the connection position of the connecting member 130 relative to the head box 120 can be selected appropriately.

[0040] Furthermore, the connector 132 has an easy-to-insert portion 132a that makes it easy to insert into the head box side hole 121, and a restricting portion 132b that restricts the connector 132 from falling out of the head box side hole 121 after being inserted into the head box side hole 121. This allows the connecting member 130 to be connected from the short side direction of the head box 120, making it easier to connect the connecting member 130 to the head box 120. Furthermore, the easy-to-insert portion 132a makes the connector 132 easy to insert, and the restricting portion 132b restricts falling out at the same time as the connector 132 is inserted, making it easier to work with.

[0041] Furthermore, since the connecting member 130 has the same connectors 132 at both ends of the cord 131, the connecting member 130 can be connected to either the bracket 110 or the head box 120 without distinguishing between the connectors 132 at both ends of the connecting member 130.

[0042] In addition, the head box side hole 121 is formed on the back side of the head box 120. Therefore, the connecting member 130 is connected to the head box 120 on the back side, which prevents the design of the front side of the blind 10 from being impaired.

[0043] Furthermore, since the connecting member 130 is composed of the cord 131 and the connector 132, the amount of hanging down from the head box 120 can be reduced by adjusting the length of the cord 131. This improves the design and also reduces interference, such as contact with the slats 12.

[0044] (Second embodiment) Next, the configuration of a blind support device 200 according to a second embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram showing the configuration of a blind 20 to which the blind support device 200 of the second embodiment is applied. In this embodiment, the configuration of the head box 220 is different from that of the head box 120 of the first embodiment. In this embodiment, differences from the first embodiment will be mainly described. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant description will be omitted.

[0045] As shown in Fig. 6, the head box 220 has a groove 221 (engaged portion) formed over the entire length in the longitudinal direction, instead of the head box side hole 121 of the first embodiment. As shown in Fig. 6(a), the groove 221 is configured such that the vertical width is narrow at the entrance 221a and wide inside. The vertical width of the entrance 221a is approximately the same as the diameter dimension of the head box side hole 121 of the first embodiment, and as shown in Fig. 6(b), the easy-to-insert portion 132a of the connector 132-2 of the connecting member 130 can be inserted into the entrance 221a. When the easy-to-insert portion 132a is entirely inserted into the groove 221, the restricting portion 132b abuts against the entrance 221a, preventing it from falling out of the groove 221.

[0046] As shown in FIG. 6(c), the groove 221 is formed continuously over the entire longitudinal length of the head box 220. Therefore, the connector 132-2 can be engaged with the groove 221 regardless of the attachment positions of the bracket 110 and the head box 220. Furthermore, after being engaged, the connector 132-2 can be moved along the groove 221 to adjust its position. Therefore, the bracket 110 and the head box 220 can be connected with the connecting member 130 regardless of the type and size of the device or the conditions at the construction site.

[0047] The connector 132-2 may be attached to the groove 221 by inserting it into the groove 221 from the end of the head box 220 in the longitudinal direction.

[0048] (Effects of the second embodiment) As described above, according to this embodiment, the engaging portion is the groove portion 221 formed along the longitudinal direction of the head box 220, and the engaging portion is the connector 132 that can be engaged with the groove portion 221, thereby increasing the degree of freedom in the connection position of the connecting member 130 relative to the head box 220.

[0049] Furthermore, since the groove 221 is formed continuously along the longitudinal direction of the head box 220, it is possible to finely adjust the connection position while the connection member 130 is connected to the head box 220.

[0050] (Third embodiment) Next, the configuration of a blind support device 300 according to a third embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing the configuration of a blind 30 to which the blind support device 300 of the third embodiment is applied. In this embodiment, the configuration of the blind 30 is different from that of the blind 10 of the first embodiment. In this embodiment, differences from the first embodiment will be mainly described. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant description will be omitted.

[0051] The blind 30 of this embodiment has a different configuration from the blind 10 of the first embodiment. As shown in Fig. 7, the blind 30 comprises a blind support device 300 which includes a bracket 310 which is fixed to a fixed surface such as a ceiling, a window frame or a wall, a head box 320 (support member) of the blind 30 which is supported by the bracket 310, and a connecting member 130 which has one end connected to the bracket 310 and the other end connected to the head box 320.

[0052] As shown in Figure 7, the blind 30 is a pleated screen, and its main components include a screen 31 with pleats formed in the vertical direction, which is hung with its upper end supported by a head box 320, a pitch cord 32 for maintaining the pitch of the pleats of the screen 31, and a lifting cord 33 for folding and unfolding the screen 31.

[0053] The upper end of pitch cord 32 is engaged in pitch cord attachment groove 321 formed along the entire length in the longitudinal direction at the lower end of head box 320. The upper end of lift cord 33 is connected within head box 320 to a mechanism (not shown) for lifting and lowering lift cord 33.

[0054] Hereinafter, the blind support device 300, which is a characteristic configuration of this embodiment, will be described with reference to Figure 7 again. As shown in Figure 7(b), the bracket 310 is provided with one bracket side hole 313 having a size and shape similar to the bracket side hole 113 of the first embodiment.

[0055] 7(a), the head box 320 is not provided with any special structure for connecting the connector 132 of the connecting member 130, and the connector 132 is engaged with the aforementioned pitch cord attachment groove 321 formed in the head box 320 for attaching the pitch cord 32, which is a component of the blinds 10. In this way, the pitch cord attachment groove 321 also serves as a head box side hole for engaging the connector 132. The width of the entrance 321a of the pitch cord attachment groove 321 is configured to be approximately the same as the diameter dimension of the head box side hole 121 in the first embodiment.

[0056] The method of connecting bracket 310 and head box 320 with connecting member 130 is the same as in the first embodiment. First, connector 132-1 of connecting member 130 is engaged with bracket side hole 313 of bracket 310. Next, head box 320 is engaged with bracket 310, and connector 132-2 is engaged with pitch cord attachment groove 321 of head box 320 at a position that does not overlap with the attachment position of pitch cord 32.

[0057] Alternatively, after the connector 132-1 is engaged with the bracket 310, the connector 132-2 may be engaged with the head box 320, and the head box 320 may be engaged with the bracket 310 while the bracket 310 and the head box 320 are connected by the cord 131.

[0058] (Effects of the third embodiment) As described above, according to this embodiment, the engaging portion also serves as the pitch cord mounting groove 321 formed for mounting components of the blind 10, so that the existing head box 320 can be reused.

[0059] In addition, pitch cord attachment grooves 321 are formed on the rear side of screen 31. Therefore, connecting member 130 is connected to head box 320 on the rear side of screen 31, preventing the design of blind 30 on the front side from being impaired.

[0060] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0061] For example, in the first embodiment described above, the connector 132 of the connecting member 130 is configured to be engaged with the bracket-side hole 113 of the bracket 110, but the present invention is not limited to this example. For example, a configuration in which one end of the connecting member is fixed to the bracket may also be used. The same applies to the other embodiments.

[0062] Furthermore, in the first embodiment, a long cord 131 is used for the connecting member 130, but the present invention is not limited to this example. Any design can be used as long as it can connect the bracket and the support member. For example, a chain, a wire, etc. may be used. The same applies to the other embodiments.

[0063] Furthermore, in the first embodiment, multiple head box side holes 121 are formed along the entire length of the head box 120 in the longitudinal direction, but the present invention is not limited to this example. Even if the mounting position of the bracket relative to the support member varies depending on the type and size of the blind, any design is possible as long as the connecting position of the connecting member relative to the support member can be adjusted to match that position.
