Detailed Description

Hereinafter, embodiments of the present invention will be described. Various feature items shown in the embodiments shown below may be combined with each other. In addition, each feature independently establishes the invention.

[ 1 ] embodiment ]

[ 1-1 ] Overall Structure ]

As shown in fig. 1, the shade apparatus 10 is provided with a safety tool (safety tool)1, and the safety tool 1 is attached to an annular operation cord suspended from a shade apparatus main body attached to a building or the like. The shade device body corresponds to, for example, a head box (head box) or a head rail (head rail). In an embodiment, the screening arrangement 10 is a pleated screen. In the embodiment, the shade device main body corresponds to the upper beam 11 of the pleated curtain, and the operation cord corresponds to the ball chain (ball chain) 15.

As shown in fig. 1 to 3, the shielding device 10 includes a shielding member 12 made of pleated curtain cloth or the like. The shading device 10 includes: safety tool 1, upper beam 11, shield 12, lifting rope 13, bottom beam (bottom rail)14, ball chain 15. The safety tool 1 includes a mounting body 2 and a moving portion 3. As shown in fig. 3, the attachment body 2 is fixed to an attachment body W of a building, and in the state shown in fig. 1, the moving part 3 is hung on a ring part (a lower end of the ring) of the ball chain 15.

The attached body W shown in fig. 3 corresponds to various structures constituting a building, furniture such as a cabinet disposed in the building, and the like. Various structures constituting the building constitute, for example, a side surface portion or a ceiling portion facing a space (living room space) in which the upper beam 11 (the shielding device main body) is disposed. The side surface portions are, for example, side walls, windows, window frames, outer peripheral walls of pillars, and the ceiling portion is, for example, a ceiling wall, a room beam, and the like. In the embodiment, the mounted body W is a side wall of a structure of a building.

The upper beam 11 includes a bracket (blacket) 11A, a pulley (pully) 11B, and the like. The bracket 11A is fixed to a body to be attached such as an upper frame of a window. Thereby, the shielding device 10 is fixed to the body W to be mounted. A belt wheel 11B for hanging the ball chain 15 is arranged in the upper beam 11. A rotation mechanism such as a reel, not shown, is provided in the upper beam 11. The screen 12 is suspended supported on the upper beam 11. The lower end of the screen 12 is mounted to the lower beam 14. One end side of lift cord 13 is attached to a rotating mechanism such as a spool in upper beam 11, and lift cord 13 can be wound around or unwound from the rotating mechanism, and the other end side of lift cord 13 is attached to lower beam 14.

When the ball chain 15 is operated to rotate the pulley 11B, the rotation mechanism in the upper beam 11 is driven, and thereby the lift cord 13 is wound on or unwound from the spool. Ball chain 15 has a front portion 15A and a rear portion 15B. The front portion 15 is a portion of the ball chain 15 located on the front side than the rear portion 15B. The front portion 15A and the rear portion 15B are connected via a ring lower end. When the lift cord 13 is wound around the spool of the upper beam 11, the lower beam 14 is raised, and thereby the screen 12 is raised upward while being folded. When the lift cord 13 is unwound from the spool of the upper beam 11, the lower beam 14 is lowered, and the shield 12 is thereby lowered downward while being extended from the folded state.

[ 1-2 ] safety tool 1 ]

As shown in fig. 6 and 7, the safety tool 1 includes a mounting body 2 and a moving portion 3.

[ 1-2-1 ] Mount body 2 ]

As shown in fig. 3, 17, and 18, the mounting body 2 has a fixing portion 2A and a mounting portion 2B. The attachment body 2 is fixed to an attachment subject W or an upper beam 11 (a shielding device main body) disposed in a building.

< fixed part 2A >

As shown in fig. 3, 17, and 18, the fixing portion 2A is attached to the body W to be attached or the upper beam 11, and the fixing portion 2A is formed in a plate shape, for example. The fixing portion 2A has a front face 2A1 and a rear face 2A 2. The mounting portion 2B is attached to the surface 2a 1. The back surface 2a2 is fixed to the body W to be mounted or the upper beam 11. The method of fixing the back surface 2a2 to the body W to be mounted or the upper beam 11 is not particularly limited. For example, an adhesive layer (e.g., an adhesive seal or an adhesive) may be formed on the back surface 2a2, and the configuration may be such that: the fixing portion 2A is fastened to the body W to be mounted or the upper beam 11 with screws. Further, the present invention may be configured as follows: the fixing portion 2A itself is made of a magnetic material, and the fixing portion 2A is fixed to the body W to be mounted or the upper beam 11 by magnetic force. Further, the following may be configured: a magnet as another member independent from the fixing portion 2A is provided on the back surface 2A2 of the fixing portion 2A. Further, the configuration may be such that: the fixing portion 2A and the body to be attached W are fixed by hook and loop fasteners (hook and loop fastener). That is, one of the fixing portion 2A and the body W to be attached includes a hook portion, and the other includes a ring portion.

< mounting part 2B >

The mounting portion 2B has a function of supporting the moving portion 3. The mount 2B is attached to the surface 2a1, the mount 2B projecting in a direction from the back surface 2a2 side toward the surface 2a1 side. The attachment portion 2B has a shaft portion 2B1 and an enlarged portion 2B 2. Since the mounting portion 2B has the shaft portion 2B1, the movable portion body 3A described later can rotate relative to the mounting body 2. The shaft portion 2B1 is attached to the surface 2a 1. As shown in fig. 8, in a state where the moving portion 3 is mounted on the mounting body 2, the moving portion 3 is supported on the mounting body 2 by the shaft portion 2B 1. Specifically, in the embodiment, the moving unit 3 is hung on the shaft 2B1, and the moving unit 3 engages with the shaft 2B 1. As a result, the moving portion 3 is supported by the mounting portion 2B by the shaft portion 2B 1. The enlarged portion 2B2 is disposed in the moving unit body 3A in a state where the moving unit 3 is attached to the attachment body 2.

The diameter of the shaft portion 2B1 is smaller than the diameter of the enlarged portion 2B 2. The diameter of the shaft portion 2B1 is smaller than the diameter of the second hole 3a2 of the engagement hole 3a1 described later, and the diameter of the enlarged portion 2B2 is larger than the diameter of the second hole 3a2 of the engagement hole 3a 1. Therefore, in a state where the shaft portion 2B1 is inserted into the second hole portion 3A2 of the engagement hole portion 3A1, even if the user pulls the attachment body 2 toward the user side, the movable portion main body 3A does not fall off the attachment body 2.

[ 1-2-2 ] moving part 3 ]

As shown in fig. 9 to 16, the moving unit 3 includes a moving unit main body 3A, a hanging unit 3B, and a turning unit 3C.

The moving unit 3 is configured to be capable of switching between a first state and a second state. As shown in fig. 3, in the first state, the moving portion 3 is disposed on the ring portion of the ball chain 15. As shown in fig. 4 and 5, in the second state, the moving portion 3 is arranged at a position further above the position at the time of the first state, and the loop portion of the ball chain 15 is exposed from the moving portion 3.

< moving part body 3A >)

The moving part body 3A is a housing provided with various members. As shown in fig. 3 to 5, the moving portion body 3A is configured to be movable along the ball chain 15. The ball chain 15 passes through the moving part body 3A. Here, in a state where the moving portion 3 is attached to the attached body W or the upper beam 11, the ball chain 15 is provided to be movable with respect to the moving portion main body 3A, and thereby the ball chain 15 can be operated.

As shown in fig. 8, 10, and 11, the moving unit main body 3A includes an engagement hole 3A1 and a curved surface 3A 2. The engagement hole 3A1 is formed in the moving-portion main body 3A. Mounting portion 2B of mounting body 2 is inserted into engagement hole 3a 1. The engagement hole 3a1 includes a first hole 3a1 and a second hole 3a 2. The first hole 3a1 is a substantially circular hole, and the first hole 3a1 is disposed below the second hole 3a 2. The first hole section 3a1 is connected to the second hole section 3a 2. The diameter of the second hole section 3a2 is smaller than the diameter of the first hole section 3a 1.

When the user mounts the moving unit 3 to the mounting body 2, the user brings the first hole 3a1 of the moving unit 3 to the position of the shaft 2B1 of the mounting body 2 (i.e., the position of the proximal end of the mounting body 2), and inserts the shaft 2B1 of the mounting body 2 into the first hole 3a1 of the moving unit 3. Then, the user lowers the movable portion 3 to relatively move the position of the shaft portion 2B1 from the first hole 3a1 to the second hole 3a 2. Thereby, the moving portion 3 and the shaft portion 2B1 are engaged. In a state where the moving portion 3 is engaged with the shaft portion 2B1, the moving portion 3 can rotate about the shaft portion 2B 1. That is, the user can adjust the angle of the moving unit 3 to a desired angle. Therefore, the operability of the ball chain 15 is improved.

As shown in fig. 11, the engagement hole 3a1 is formed with a narrow portion 3a 3. The width of the narrow-width portion 3a3 is smaller than the diameter of the shaft portion 2B 1. Therefore, the shaft portion 2B1 engaged with the second hole portion 3a2 does not easily move toward the first hole portion 3a 1.

As shown in fig. 16, a housing space Sp is formed in the moving part body 3A. The ball chain 15 is movably disposed in the housing space Sp, and the enlarged portion 2B2 is disposed in the housing space Sp in a state where the moving portion 3 is attached to the attachment body 2.

As shown in fig. 9 and 10, an elongated opening Op1 is formed in the upper portion of the moving part body 3A. By forming the opening part Op1 in the moving part main body 3A, the user can move the moving part main body 3A in the direction along the ball chain 15. As shown in fig. 16, the moving part main body 3A is formed with a curved surface part 3A 2. The curved surface portion 3a2 is provided on the inside edge portion provided at the formation position of the opening portion Op 1. The moving section main body 3A is formed with a pair of curved surface sections 3A2, and the pair of curved surface sections 3A2 face each other. The interval between the pair of curved surface portions 3a2 gradually decreases from the upper side toward the lower side. By forming the curved surface portion 3a2, when the user operates the ball chain 15, the ball chain 15 smoothly moves along the curved surface portion 3a 2. Therefore, interference between the ball chain 15 and the moving part body 3A is suppressed, whereby the operability of the ball chain 15 is improved. In addition, when the user pulls down the front portion 15A of the ball chain 15, the rear portion 15B rises. Here, by forming the curved surface part 3A2, the rear part 15B is less likely to be caught on the edge of the opening part Op1 of the moving part main body 3A. Therefore, when the user pulls down the front portion 15A of the ball chain 15, the moving portion main body 3A can be suppressed from rising together with the rear portion 15B.

As shown in fig. 8, 16, a pair of insertion portions Op2 are formed in the moving part main body 3A. The front part 15A of the ball chain 15 is inserted into one (front side) insertion part Op2, and the rear part 15B of the ball chain 15 is inserted into the other (rear side) insertion part Op 2. In addition, as shown in fig. 14, 16, the lower part of the moving part main body 3A is formed with an open part Op 3. By forming the open part Op3 in the moving part main body 3A, when the user moves the moving part main body 3A in the state shown in fig. 1 (first state) toward the upper side, the lower part of the moving part main body 3A does not interfere with the loop part of the ball chain 15. That is, by forming the opening part Op3 in the moving part main body 3A, the user can move the moving part main body 3A in the direction along the ball chain 15. In this way, the moving part 3 is formed with the opening part Op1, the insertion part Op2, and the opening part Op3, and therefore, the moving part main body 3A (moving part 3) is provided to be movable with respect to the ball chain 15.

< hanging part 3B >

As shown in fig. 8, 9, and 14, the hanging portion 3B is provided on the left side surface of the moving portion main body 3A. The hanging part 3B has a function of hanging the moving part 3 on the ball chain 15. By providing the hanging portion 3B on the moving portion 3, the user can hang the hanging portion 3B at a position on the ball chain 15 that is higher than the portion inserted into the moving portion 3. Thereby, the position of the ring portion of the ball chain 15 and the position of the moving portion 3 move upward. As a result, the ball chain 15 or the moving part 3 can be more reliably prevented from being caught on the human body.

As shown in fig. 8, 9, and 14, the hanging portion 3B has an arm portion 3B 1. The arm portion 3B1 extends from the upper side of the moving portion main body 3A toward the lower side of the moving portion main body 3A. The lower end of the arm portion 3B1 is formed with a projection 3B 2. In addition, a protrusion 3B3 is formed on the left side surface of the moving part main body 3A. Projection 3B2 and projection 3B3 are opposed to each other. A gap 3B4 is formed between the arm portion 3B1 and the left side surface of the moving portion main body 3A. The gap 3B4 allows the ball chain 15 to be inserted. That is, when the user hangs the hanging portion 3B on the ball chain 15, the user presses the ball chain 15 between the protrusion 3B2 and the protrusion 3B3, and inserts the ball chain 15 into the gap 3B 4.

< turning part 3C >

As shown in fig. 8, 14, and 16, the turning section 3C is disposed inside the moving section main body 3A. The turning portion 3C is disposed on the lower side of the moving portion body 3A. When the moving portion 3 is in the state shown in fig. 1 (first state), the steering portion 3C is supported on the loop portion of the ball chain 15. The turning portion 3C is provided in the moving portion body 3A, so that the moving portion body 3A can be prevented from falling off the ball chain 15. The turning portion 3C is formed with an abutment surface 3C 1. The contact surface 3C1 has a curved surface projecting downward. Therefore, the contact surface 3C1 is formed in a shape along the loop portion of the ball chain 15, thereby improving the operability of the ball chain 15. The configuration of the steering portion 3C is not limited to this, and for example, the steering portion 3C may be configured by a pulley provided rotatably on the moving portion main body 3A.

[ 1-2-3 ] about the separation section 15c ]

As shown in fig. 2A, the ball chain 15 includes a separating portion 15c in addition to the plurality of ball portions 18 and the plurality of connecting portions 19. The coupling portion 19 includes a coupling portion that couples the two ball portions 18, and a coupling portion that couples the ball portion 18 and the separation portion 15 c.

The separating portion 15c is configured to: when an operating force exceeding a threshold value acts on the ball chain 15, the ball chain 15 is changed from the annular state to the non-annular state. That is, the separating portion 15c has: when an operating force exceeding a threshold value acts on the ball chain 15, it is separated into functions of a plurality of parts. The operation force may be a force acting on the ball chain 15 when the user directly grips the ball chain 15, or may be a force acting on the ball chain 15 when the user grips the moving part body 3A.

When the ball chain 15 is operated by the user and the ball chain 15 moves, the separating portion 15c can pass through the moving portion body 3A. That is, the moving part body 3A is configured to: separation part 15c can pass through opening part Op1, insertion part Op2, and opening part Op 3.

An example of the structure of the separating portion 15c will be described with reference to fig. 28 and 29. The separating portion 15c includes a pair of first fitting portions 43 and a second fitting portion 42. The separating portion 15c is configured to: even if the first fitting portion 43 and the second fitting portion 42 are separated, they can be fitted again.

A fitting projection 45 having a shape of a bag (japanese: Biao) in cross section is formed at a tip end portion of the first fitting portion 43, and an expanded portion 46 expanded in a longitudinal direction of the bag is formed at a tip end portion of the fitting projection 45. The expanded diameter portion 46 has recesses 47 formed on the outer peripheral surface of both sides in the longitudinal direction. The front end corner of the expanded diameter portion 46 is formed with a chamfered portion 49. The chamfered portion 49 is formed on the first fitting portion 43, so that the user can easily insert the first fitting portion 43 into the second fitting portion 42. Further, a rotation restricting portion 48 protruding in the radial direction of the fitting projection 45 is formed on the base end portion of the fitting projection 45.

The second fitting portion 42 is a cylindrical member. A fitting hole 49a is formed in a distal end portion of the second fitting portion 42. The fitting hole 49a is open in the shape of a bag, and thus the expanded diameter portion 46 of the fitting projection 45 can be inserted. The fitting hole 49a is formed in a circular shape with a diameter that allows the fitting protrusion 45 to rotate in the fitting hole 49 a. A locking portion 49b that engages with the expanded diameter portion 46 is formed in the fitting hole 49 a. The opening edge of the locking portion 49b is cut in an arc shape so that the base end portion of the fitting projection 45 can be turned. Engaging portions 49b are formed on the upper surface side and the lower surface side of the second fitting portion 42, respectively. The arrangement position of the engaging portion 49b on the upper surface side of the second fitting portion 42 and the arrangement position of the engaging portion 49b on the lower surface side of the second fitting portion 42 form an angle of 90 degrees.

When the user inserts the expanded diameter portion 46 and the rotation restricting portion 48 of the first fitting portion 43 into the fitting hole 49a and rotates the first fitting portion 43 by 90 degrees, the convex portion (not shown) of the second fitting portion 42 is fitted into the concave portion 47 of the first fitting portion 43. Thereby, the first fitting portion 43 and the second fitting portion 42 are fitted. When the user wants to further rotate the first fitting portion 43, the rotation restricting portion 48 interferes with the second fitting portion 42. Therefore, the rotation of the first fitting portion 43 is restricted.

[ 1-3-1. operation in the first State ]

As shown in fig. 3, when the moving portion 3 is in the first state, the user grips the exposed portion 15a of the ball chain 15, and the user performs a downward pulling operation on the ball chain 15, whereby the pulley 11B rotates and the shade 12 ascends or descends. In the first state, the moving portion 3 is provided on the ring portion of the ball chain 15. Then, when the moving part 3 is in the first state, the loop part of the ball chain 15 is shielded by the moving part 3. Therefore, when the moving part 3 is in the first state, the loop part of the ball chain 15 hanging down can be prevented from catching on the human body.

When the moving unit 3 is in the first state, the lower side of the ball chain 15 is accommodated in the moving unit 3. If the lower side of the ball chain 15 is not accommodated in the moving portion 3, the distance in the front-rear direction between the lower side of the front portion 15A and the lower side of the rear portion 15B is likely to be increased, thereby deteriorating the design of the shade device 10 (see fig. 2B). However, in the embodiment, when the moving portion 3 is in the first state, the lower side of the ball chain 15 is accommodated in the moving portion 3, and therefore, the lower side position of the front portion 15A and the lower side position of the rear portion 15B are defined by the moving portion 3. As a result, as shown in fig. 2A, the front-rear direction interval Wt between the front portion 15A and the rear portion 15B is the same from the ring portion side of the ball chain 15 toward the pulley 11B side of the upper beam 11. Therefore, according to the safety tool 1 of the embodiment, the design of the shade device 10 can be improved.

[ 1-3-2 ] operation in the second State

As shown in fig. 4 and 5, when the moving portion 3 is in the second state, the user grips the exposed portion 15a of the ball chain 15, and the user pulls down the ball chain 15, whereby the pulley 11B rotates and the shade 12 ascends or descends. In the second state, the moving portion 3 is arranged at a position higher than the position in the first state. Further, even if the user pulls down the ball chain 15, the moving portion 3 is not detached because the moving portion 3 is attached to the attachment body 2. In addition, when the moving portion 3 is in the second state, the ball chain 15 avoids the shade 12. Therefore, when the user operates the ball chain 15, the ball chain 15 is less likely to interfere with the shield 12. Therefore, according to the safety tool 1 of the embodiment, the operability of the ball chain 15 can be suppressed from being lowered.

Further, as shown in fig. 4, 5, when the moving portion 3 is in the second state, the exposed portion of the ball chain 15 includes not only the exposed portion 15a but also the exposed portion 15 b. Therefore, when the user grips the exposed portion 15B of the ball chain 15 and pulls down the ball chain 15, the pulley 11B rotates and the shade 12 moves up or down.

In addition, as shown in fig. 4 and 5, when the moving portion 3 is in the second state, the loop portion of the ball chain 15 is exposed from the moving portion 3. However, when the moving part 3 is attached to the attachment body 2, the height position of the moving part 3 is higher than the height position of the moving part 3 in the first state. As a result, the height position of the loop portion of the ball chain 15 is higher than the height position of the moving portion 3 in the first state. Therefore, even when the moving unit 3 is in the second state, the loop portion of the ball chain 15 hanging down can be prevented from catching on the human body.

[ 1-3-3 ] mounting and dismounting operations of the moving section 3 ]

The user grips the moving part 3 in the first state and moves the moving part 3 upward along the ball chain 15. Thereby, the state of the moving unit 3 is switched from the first state to the second state (act 1). Then, the ball chain 15 and the moving part 3 are moved from the shield 12 side toward the mounting body 2 side (right side), and the moving part 3 is brought close to the mounting body 2 (act 2). Note that, the order of the operation 1 and the operation 2 may be reversed or performed simultaneously (in parallel).

Then, the user places moving part 3 and mounting body 2 so as to face each other, and inserts mounting portion 2B of mounting body 2 into first hole 3a1 formed in engagement hole 3a1 of moving part 3 (act 3). Further, the user lowers the moving unit 3 in the state after the end of the operation 3 (operation 4). Thereby, second hole 3a2 of engaging hole 3a1 engages with mounting portion 2B. After the user completes the operation 4, the moving unit 3 is attached to the attachment body 2.

In the state after the end of act 4, since moving part 3 is engaged with mounting body 2, moving part 3 does not fall off mounting body 2. The attachment body 2 is disposed on the side surface side (right side) of the shielding device 10. That is, the attachment body 2 is arranged at a position apart from the shade, and therefore, the ball chain 15 is arranged to avoid the shade 12 by the moving portion 3 being attached to the attachment body 2. Therefore, even if the user operates the ball chain 15 by gripping the exposed portion 15a or the exposed portion 15b of the ball chain 15 and the ball chain 15 shakes, the ball chain 15 can be prevented from interfering with the shade 12. As a result, according to the safety tool 1, the operability of the ball chain 15 can be suppressed from being lowered.

When the user detaches the moving unit 3 from the attachment body 2, the above-described operations 1 to 4 are performed in reverse order. That is, the user raises the moving unit 3 (act 5). This releases the engagement between second hole 3a2 of engagement hole 3a1 and mounting portion 2B. Next, the user separates moving part 3 from mounting body 2 so that mounting part 2B of mounting body 2 is pulled out from first hole 3a1 formed in engagement hole 3a1 of moving part 3 (act 6). Then, the user moves the ball chain 15 and the moving part 3 from the attachment body 2 side toward the shade 12 side (left side) (act 7). The user moves the moving part 3 downward along the ball chain 15, and moves the moving part 3 to the ring part of the ball chain 15 (act 8).

[ 1-4 ] effects of embodiments ]

In the conventional safety tool, since the steering portion is disposed near the front of the shield, the ball chain may be shaken when the user operates the ball chain, and the ball chain may interfere with the shield. Thus, if the operation cord interferes with the shield, the user may feel troublesome when operating the operation cord. The moving unit 3 of the safety tool 1 according to the embodiment is configured to: the mounting structure is attachable to and detachable from an object W or an upper beam 11 disposed in a building. Therefore, the user can attach the moving part 3 to the body W or the upper beam 11 so that the ball chain 15 avoids the shade 12. In a state where the moving unit 3 is attached to the body W or the upper beam 11, even if the ball chain 15 is operated by the user and the ball chain 15 shakes, the ball chain 15 avoids the shade 12, and therefore the ball chain 15 is less likely to interfere with the shade 12. Therefore, according to the safety tool 1 of the embodiment, the operability of the ball chain 15 can be suppressed from being lowered. In a state where the moving part 3 is attached to the attached body W or the upper beam 11, a portion (exposed portion 15a) of the ball chain 15 on the upper side of the moving part 3 or a portion (exposed portion 15b) of the ball chain 15 on the lower side of the moving part 3 is exposed from the moving part 3, and thus can be operated.

[ 1-5. variants ]

[ 1-5-1 ] variation of safety tool 1 ]

In the embodiment, the moving portion 3 is supported by the attachment body 2 via the shaft portion 2B1, but the present invention is not limited to this form.

The moving part 3 may be attached to the attachment body 2 by magnetic force. That is, as shown in fig. 19, magnets mg may be provided on the moving part 3 and the mounting body 2, respectively, and the moving part 3 may be mounted on the mounting body 2 by the magnetic force of these magnets.

The moving part 3 may be attached to the attachment body 2 by hook and loop fasteners (hook and loop fastener).

In the embodiment, the mounting body 2 and the moving part 3 are configured independently, but the present invention is not limited to this configuration. The following may be configured: the attachment body 2 and the moving part 3 are not independent, but the attachment body 2 and the moving part 3 (moving part body 3A) are connected. In this case, the attachment body 2 preferably functions as a suction cup. Thus, the moving part 3 can be fixed to the body to be mounted or the shielding apparatus body by pressing the body 2 to be mounted or the shielding apparatus body.

If the front portion 15A of the ball chain 15 and the rear portion 15B of the ball chain 15 cross each other, the operation of the ball chain 15 may be hindered. Therefore, as shown in fig. 20 and 21, the moving part 3 may also have a cross prevention part 3D.

The crossover preventing portion 3D is formed in the housing space Sp. The cross prevention unit 3D is configured to: in a state where the ball chain 15 (operation cord) is passed through the moving part 3, the front part 15A of the ball chain 15 and the rear part 15B of the ball chain 15 do not intersect. In other words, the cross preventing unit 3D is configured to: in a state where the ball chain 15 passes through the moving portion 3, the side where the front portion 15A is located and the side where the rear portion 15B is located are spaced apart from each other.

The cross prevention portion 3D is formed by: projects from one of the pair of inner surfaces 3b1, 3b2 opposed to each other toward the other. More specifically, the cross preventing portion 3D is formed by: projecting from the inner surface 3b1 towards the inner surface 3b 2. Further, curved surfaces 3D1 are formed on the upper surface of the cross prevention section 3D and the lower surface of the cross prevention section 3D, respectively. This can prevent the ball chain 15 from being caught by the cross preventing portion 3D, and can make the operation of the ball chain 15 smoother.

As shown in fig. 20, a gap Op4 is formed between the end surface of the cross prevention portion 3D and the inner surface 3b 2. The size of the gap Op4 is configured to be: the string part (the part between the adjacent balls) of the ball chain 15 can be made to pass through the gap Op4, but the balls of the ball chain 15 cannot pass through the gap Op 4. For example, the size of the gap Op4 is the same size as the diameter of the rope portion, preferably smaller than the diameter of the ball.

As shown in fig. 21, the width of the cross prevention unit 3D in the vertical direction is preferably larger than the length of the string of the ball chain 15. Thereby, even if the rope portion tries to enter the gap Op4, the ball interferes with the cross prevention portion 3D, whereby the front portion 15A and the rear portion 15B can be more reliably prevented from passing through the gap Op 4.

As shown in fig. 21, the width of the cross prevention portion 3D in the front-rear direction (direction from the front portion 15A toward the rear portion 15B) is preferably smaller than the length of the string portion of the ball chain 15. Thereby, the user can attach the ball chain 15 to the moving part 3. That is, the user is to pass the string part of the ball chain 15 through the gap Op4 of the moving part main body 3A in a state where the moving part main body 3A and the turning part 3C are separated. Then, the user pulls out the loop lower end of the ball chain 15 from the lower side of the moving part body 3A. Further, the user connects the moving part body 3A and the turning part 3C in a state where the lower end of the loop is hung on the turning part 3C. Through these operations, the user can attach the ball chain 15 to the moving part 3.

As shown in fig. 21, the ball chain 15 may also be provided with a stopper (stopper)15 d. The restrainer 15d is mounted on the string portion between the adjacent two balls. The limiter 15d has a function of limiting the operable range of the ball chain 15. For example, when the user continuously pulls down the front portion 15A of the ball chain 15, the stopper 15d rises and interferes with the pulley 11B (refer to fig. 1). As a result, the user cannot pull down the front portion 15A of the ball chain 15. The same applies to the case where the user continues to pull down the rear portion 15B of the ball chain 15.

Here, the insertion part Op2 is a portion through which the ball chain 15 passes, and the insertion part Op2 is narrower than the housing space Sp. In the present modification, the stopper 15d is configured to be able to pass through the moving portion 3. That is, the restrainer 15d is sized to be disposed between two adjacent balls of the ball chain 15, and therefore, the restrainer 15d can pass through the insertion part Op 2.

As shown in fig. 22A and 22B, the attachment body 2 may be configured by a frame (bracket) that can slide the moving section 3 in the vertical direction. That is, in the support mode of the embodiment, the shaft portion 2B1 is configured to support the moving portion 3 pivotally, but is not limited to the pivotally support. The mounting body 2 may be constituted by a frame structure that houses the moving section 3. The dotted line in fig. 22A indicates the inner side portion of the attachment body 2. The broken line in fig. 22B indicates a portion of the moving part 3 shielded by the attachment body 2. A hooking portion 2c is formed at the lower side of the inside of the mounting body 2, and when the moving portion 3 is moved downward while sliding the moving portion 3 with respect to the mounting body 2, the lower portion of the moving portion 3 is hooked on the hooking portion 2 c. In the third embodiment of the present modification, the outer peripheral surface of the moving portion 3 is supported by the attachment body 2. Therefore, when the user operates the ball chain 15, the load applied to the moving portion 3 is effectively dispersed.

The safety tool 1 may be formed in the following manner in addition to the above-described embodiment.

The safety tool 1 may be configured such that the moving portion 3 and the attachment body 2 are engaged with each other in a concave-convex manner. That is, the following configurations are possible: one of the moving part 3 and the mounting body 2 has a convex part, and the other of the moving part 3 and the mounting body 2 has a concave part engaged with the convex part.

The safety tool 1 may be configured such that the moving part 3 and the attachment body 2 are fixed by a pin member (rod member). That is, the moving portion 3 and the mounting body 2 are formed with hole portions into which the pin members are inserted, respectively. Then, the user inserts the fixing member into the hole of the moving part 3 and the hole of the attachment body 2 while the holes are overlapped. Even in this embodiment, the moving part 3 can be easily attached to the attachment body 2, and the moving part 3 can be easily detached from the attachment body 2.

The safety tool 1 may be configured such that the attachment body 2 has a belt-like member (e.g., a rubber belt) with elasticity. The user can mount the moving part 3 on the mounting body 2 by clamping the moving part 3 with a band (belt) provided on the mounting body 2.

[ 1-5-2 ] modifications of the shade device

The applicable objects of the safety tool 1 are not limited to the pleated blinds described in the embodiments.

As shown in fig. 23, the safety tool 1 may also be adapted for use on a roman shade, for example. The roman shade is a shade device in which the shade 12 is configured to be foldable in a corrugated shape.

As shown in fig. 24, the safety tool 1 may also be adapted to be used on a roller blind, for example. The rolling shutter is a shielding device in which the shield 12 is configured to be wound on or unwound from a reel, not shown.

As shown in fig. 25, the safety tool 1 may also be adapted for use on a vertical blind, for example. The vertical blind is a shielding device configured such that a plurality of plate-like shields 12 extending in the vertical direction can rotate about an axis parallel to the vertical direction.

As shown in fig. 26, the safety tool 1 may also be adapted for use on a horizontal blind, for example. The horizontal blind is a shielding device in which a plurality of shields 12 configured in a plate shape extending in the left-right direction are rotatable.

As shown in fig. 27, the safety tool 1 may also be applied to a curtain rail (curve), for example. The curtain rail is a shielding device in which a plurality of members 30 configured to support a curtain (shielding material), not shown, are provided on a rail extending in the left-right direction.
