Definitions

  • the present invention relates to a curtain accessory for bunching a curtain.
  • JP 2006-130130 A both disclose a tassel for bunching a curtain.
  • the tassel is provided with magnetic coupling means at both of its ends for closing the tassel.
  • JP 2007-177440 A discloses an endless operation cord for operating a horizontal-type blind.
  • the ends of the operation cord are coupled together by means two fitting members molded onto the ends of the cord.
  • a tassel hook, on which a tassel for bunching a curtain is hooked, is typically fixed, as disclosed in JP 11-169284 A .
  • loop strings are typically attached to both edges of a tassel band of a curtain in such a manner that the loop strings are prevented from slipping off the tassel main body, as disclosed in JP 2012-165993 A .

  • the tassel hook is configured to self-release the tassel cord hooked on the tassel hook, when the curtain is operated manually or by remote control while the tassel cord is hooked.
  • a tassel holder thereof is fixed and therefore does not come off even when a strong force is applied thereto. Accordingly, when a tassel is hooked on this tassel hook and forms a loop, a foreign object may be caught on the loop, causing a safety problem.
  • the loop strings are fixed to the tassel main body and therefore does not become detached even when a string force is applied thereto. Accordingly, when the tassel is hooked on a tassel hook using these loop strings and forms a loop, a foreign object may be caught on the loop, causing a safety problem.
  • the present invention has been made in view of the foregoing, and an object thereof is to provide a technology that improves the safety of a curtain accessory for bunching a curtain.
  • the present invention provides a curtain accessory for bunching a curtain as defined in the claims.
  • the curtain accessory includes a tassel, a tassel hook, and a tassel auxiliary part for ensuring safety when attaching the tassel to the tassel hook.
  • a coupling mechanism is disposed on the tassel auxiliary part. The coupling mechanism is configured in such a manner that, when a load applied to the tassel exceeds a predetermined value, the coupling mechanism is decoupled, as well as can be recoupled after being decoupled.
  • the term "curtain accessory” may refer to an single member, such as a tassel alone, a tassel hook alone, or a tassel auxiliary part alone, or may refer to two members, such as a combination of a tassel hook and a tassel auxiliary part, or may refer to three members, such as a combination of a tassel, a tassel hook, and a tassel auxiliary part.
  • the term “decoupled” includes the meaning that a specific area in a member is relatively rotated, or deformed and thus a tassel is allowed to drop off a tassel hook, as in seventh and eighth embodiments. In this case, the term “recoupled” means that the relatively rotated or deformed area is restored to its original state and thus the tassel hook is allowed to hold the tassel again.
  • the tassel auxiliary part is provided with a circular part, and the coupling mechanism includes a separation part configured to separate the circular part to make the circle noncircular.
  • the coupling mechanism includes a separation part configured to separate the tassel or the tassel auxiliary part from the tassel hook by a pulling force.

  • the coupling mechanism is covered by a hiding member or a decoration member.
  • a looped tassel cord to which the tassel auxiliary part is locked is disposed on one edge of the tassel, the looped tassel cord being configured in such a manner that the looped tassel cord cannot be hooked on the tassel hook, and another looped tassel cord to be hooked on the tassel hook is disposed on another edge of the tassel.
  • the curtain accessory further includes holding means configured to hold at least one or a part thereof of the members consisting of the tassel, the tassel hook, and the tassel auxiliary part, the at least one member or the part thereof being prevented from falling down when the coupling mechanism is coupled, so that the at least one member or the part thereof is prevented from falling on a floor even when the coupling mechanism is decoupled.
  • the coupling mechanism has a fitting structure.
  • the fitting structure is a rotating fitting structure and is configured in such a manner that the fitting structure can be refitted after decoupled by rotating the fitting structure manually.
  • the coupling mechanism is configured to be decoupled when the load applied to the tassel exceeds 2kgf.
  • a curtain accessory having high safety can be obtained.
  • Fig. 1 includes diagrams showing the structure and use aspect of a tassel auxiliary part 100 of the present embodiment which can be attached to an existing tassel hook 200 or a tassel 300.
  • Fig. 2 includes diagrams showing a mechanism in which application of a predetermined load to the tassel auxiliary part 100 of the present embodiment separates a separation part 114 of the tassel auxiliary part 100, unloops the looped tassel auxiliary part 100, and detaches one tassel cord of the tassel 300 from the tassel hook 200.
  • a curtain accessory 1000 of the present embodiment is an accessory for bunching a curtain 1100.
  • the curtain accessory 1000 includes three members: the tassel 300, tassel hook 200, and tassel auxiliary part 100.
  • the tassel auxiliary part 100 is an auxiliary part for ensuring safety when the tassel 300 is attached to the tassel hook 200.
  • the curtain accessory 1000 only has to include at least one (e.g., the tassel auxiliary part 100) of the three members. Since the tassel auxiliary part 100 shown in Fig. 2(a) can be attached to an existing tassel hook or tassel, it may be sold alone as the curtain accessory 1000.
  • a coupling mechanism [e.g., the separation part 114 shown in Fig. 1(a) ] is disposed on at least one (e.g., the tassel auxiliary part 100) of the three members, or between adjacent members (a specific example will be described later).
  • the coupling mechanism e.g., the separation part 114
  • This coupling mechanism is configured in such a manner that it can be recoupled after decoupled.
  • the tassel 300 or tassel auxiliary part 100 is provided with a circular part [e.g., a loop formed by a cord 111 of the tassel auxiliary part 100 shown in Fig. 1(a) ].
  • the coupling mechanism includes the separation part 114 that separates the circular part [e.g., the loop formed by the tassel auxiliary part 100 shown in Fig. 2(a) ] to make the tassel auxiliary part 100 noncircular [e.g., the tassel auxiliary part 100 in the shape of a linear string shown in Fig. 2(b) ].
  • the coupling mechanism is preferably a separation part 114 having a fitting structure, as shown in Fig. 1(b) .
  • the separation part 114 in Fig. 1(b) consists of a male member (first coupling member) 115 and a female member (second coupling member) 116 molded from a synthetic resin.
  • the female member 116 is formed in a tubular shape and has a locking groove 117 circumferentially formed on the inner peripheral surface of the front end thereof.
  • the female member 116 has, in the base end thereof, an insertion hole 118 into which a cord 111a can be inserted.
  • the cord 111a is attached to the female member 116 by inserting an end of the cord 111a into the insertion hole 118 from the base end side of the female member 116, mounting a swaging member 119 on the end of the cord 111a, and swaging the swaging member 119 so that it contacts a peripheral portion of the insertion hole 118 in the female member 116, as shown in Fig. 1(b) .
  • the end of the cord 111a is held in the female member 116.
  • the male member 115 is attached to an end of a cord 111b by outsert molding. Specifically, the male member 115 is formed by performing outsert molding on the single cord 111b at predetermined intervals. Also, by cutting the cord 111b at the front end of the molded male member 115, the cord 111b having the male member 115 attached to an end thereof and having a predetermined length is formed. The other end of the cord 111b is attached to the female member 116, as described above.
  • the front end of the male member 115 is formed with a diameter that allows the front end can be fitted into the front end of the female member 116.
  • a protrusion 120 engageable with the locking groove 117 is circumferentially formed on the outer peripheral surface of the front end of the male member 115.
  • the tassel auxiliary part 100 includes the cord 111, whose ends are connected by the separation part 114.
  • the cord 111 of the tassel auxiliary part 100 forms a loop and indirectly locks the tassel 300 to the tassel hook 200.
  • a pulling force 500 is applied to the tassel auxiliary part 100.
  • the male member 115 and female member 116 of the separation part 114 are detached from each other, so that the tassel auxiliary part 100 is unlooped (noncircular) and falls on the floor.
  • the tassel auxiliary part 100 including the separation part 114 configured thus can produce the following effects.
  • the separation part 114 need not necessarily have the structure shown in Fig. 1(b) and may have any other structure.
  • Fig. 3 is an exploded perspective view showing a separation part of a tassel auxiliary part of a modification of the first embodiment. That is, the separation part 114 of the tassel auxiliary part 100 may be a coupling part 16 having a fitting structure as shown in Fig. 3 .
  • the fitting structure of the coupling part 16 is a type of rotating fitting structure. For this reason, the members of the coupling part 16 can be refitted together after detached from each other by rotating them manually.
  • the coupling part 16 consists of a first coupling member 27 and a second coupling member 28.
  • a first fitting part 29 is formed on one end of a cord 19 from a synthetic resin.
  • the first fitting part 29 has, on the front end thereof, a fitting protrusion 30 having a bale-shaped cross-section obtained by cutting off both sides of a round shank in parallel.
  • the fitting protrusion 30 has, on the front end thereof, swelled portions 31 having a diameter swelled in the long axis direction of the bale shape.
  • Troughs 32 are formed on the outer peripheral surfaces of both sides in the long axis direction of the swelled portions 31 in the axis direction of the first fitting part 29.
  • the front end corners of the swelled portions 31 are chamfered edges 33.
  • a second fitting part 34 is molded on one end of a coupling cord 23 similar to the cord 19 from the same material as the first fitting part 29.
  • the second fitting part 34 has a hemispherical base end and a front end having a fitting hole 35.
  • the fitting hole 35 has a bale-shaped opening into which the swelled portions 31 of the fitting protrusion 30 can be inserted.
  • the deep section of the fitting hole 35 is formed in a circle having a diameter that allows the fitting protrusion 30 to rotate in the fitting hole 35.
  • locking portions 37 configured to engage with the swelled portions 31 are formed at the opening of the fitting hole 35 so as to be line-symmetrical. The opening edge of each locking portion 37 is gouged out to form an arc so that the base end of the fitting protrusion 30 can rotate.
  • the first fitting part 29 and the second fitting part 34 are fitted together by inserting the swelled portions 31 of the fitting protrusion 30 into the fitting hole 35 and then rotating the first fitting part 29 in either direction.
  • the swelled portions 31 are locked to the locking portions 37 and held in the fitting hole 35.
  • This holding force is set such that when the typical curtain 1100 is bundled and locked by the tassel 300, the fitting protrusion 30 and fitting hole 35 are prevented from being detached from each other by a pulling force (preferably, less than 1kgf) acting on the tassel auxiliary part 100 against a minimum holding force required to keep the curtain bunched.
  • the fitting structure of the coupling part 16 is a type of rotating fitting structure. That is, the base end of the fitting protrusion 30 can be rotatably supported on the arc-shaped surfaces of the locking portions 37. For this reason, the fitting protrusion 30 is fitted into the fitting hole 35 by inserting the swelled portions 35 of the fitting protrusion 30 into the fitting hole 35 and then rotating the swelled portions 31 by 90 degrees. As a result, it is possible to reduce the operation force for fitting the fitting protrusion 30 into the fitting hole 35, as well as to obtain a sufficient holding force to hold the fitting protrusion 30 in the fitting hole 35.
  • the fitting protrusion 30 can be easily fitted into the fitting hole 35. Since fitting the fitting protrusion 35 into the fitting hole 35 requires only a small operation force, the fitting protrusion 30 which is detached can be refitted into the fitting hole 35 without having to use a tool. Accordingly, if the coupling part 16 is decoupled, a dweller can easily restore it to the original state. That is, after the fitting protrusion 30 and the fitting hole 35 of the coupling part 16 are detached from each other, the fitting protrusion 30 can be refitted into the fitting hole 35 by rotating the fitting protrusion 30 in the fitting hole 35. Thus, the looped tassel auxiliary part 100 can be easily reconstructed.
  • the first and second coupling members 27 and 28 are attached to the cord 111 of the tassel auxiliary part by forming hollow spaces in both ends of the cord 111 of the tassel auxiliary part, inserting the coupling cords 19 and 23 of the first and second coupling member 27 and 28 into the spaces, and sewing together the outer covering of the cord 111 of the tassel auxiliary part and the cords 19 and 23.
  • the separation part 114 need not necessarily have the structure shown in Fig. 1(b) or Fig. 3 and may have any other structure.
  • Fig. 4 is an exploded perspective view showing a separation part of a tassel auxiliary part of a modification 2 of the present embodiment. That is, the separation part 114 of the tassel auxiliary part 100 may be a coupling part 16 having a fitting structure as shown in Fig. 4 .
  • the fitting structure of the coupling part 16 is also a type of rotating fitting structure. For this reason, the members of the coupling part 16 can be refitted together after detached from each other by rotating them manually. This structure also can produce effects similar to those of the structure shown in Fig. 3 .
  • each first coupling member 41 is fixed to one end of a cord 14 and has a fitting protrusion 45 taking the shape of a round shank, on the front end thereof as a male member.
  • swelled portions 46 are formed on the outer peripheral surface of the front end of the fitting protrusion 45 so as to be line-symmetrical with respect to the center of the round shank. Troughs 47 having a semicircular cross-section are formed between the swelled portions 46.
  • rotation-restriction portions 48 are formed on the base end of the fitting protrusion 45 so as to protrude in radial directions of the round shank and to be line-symmetrical with respect to the center of the round shank.
  • the rotation-restriction portions 48 are formed in positions circumferentially spaced from the troughs 47 by 45 degrees with respect to the center of the round shank.
  • the second coupling member 42 is molded into a tubular shape from the same synthetic resin as the first fitting part 41, as a female member having a fitting hole. As shown in Fig. 4 , openings 49a and 49b on both sides of the second coupling member 42 are each formed in a bale shape into which the front end including the swelled portions 46, of the corresponding fitting protrusion 45 can be inserted. The opening portions 49a, 49b are shaped such that orientations of the respective bale shapes are mutually rotated by 90 degrees with respect to the center of the tube.
  • the second coupling member 42 has therein a circular hole having a diameter which allows the front ends of the fitting protrusions 45 to rotate.
  • Formed at opening edges in the short-axis direction of the bale shape of the opening portion 49a are locking portions for preventing the swelled portions 46 from coming out of the circular hole.
  • Formed at opening edges in the short-axis direction of the bale shape of the opening portion 49b are locking portions for preventing the swelled portions 46 from coming out of the circular hole.
  • first coupling members 41 and the second coupling member 42 are coupled together by inserting the fitting protrusion 45 of the first fitting part 41 into the opening 49a of the second coupling member 42 and then rotating the first fitting part 41 clockwise relative to the second coupling member 42.
  • the other first coupling member 41 and the second coupling member 42 are coupled together by inserting the fitting protrusion 45 of the first fitting part 41 into the other opening portion, 49b, of the second coupling member 42 and rotating the first fitting part 41 by 90 degrees for positioning.
  • the first coupling members 41 are coupled together via the second coupling member 42.
  • Fig. 5 is a diagram showing a tassel auxiliary part 100 of a modification 3 of the present embodiment.
  • a curtain accessory 1000 of the present modification may include both a tassel 300 and a tassel auxiliary part 100.
  • the separation part 114 described in the first embodiment is disposed on the tassel auxiliary part 100.
  • the tassel 300 has, on one edge thereof, a looped tassel cord having the tassel auxiliary part 100 locked thereto.
  • the looped tassel cord is configured such that it cannot be hooked on the tassel hook 200.
  • the looped tassel cord is almost covered by a hiding member 152, and a small exposed portion thereof is narrower than the hooking part of a tassel hook. Accordingly, the looped tassel cord cannot be hooked on the tassel hook 200.
  • the tassel 300 has, on the other end thereof, another looped tassel cord 150 to be hooked on the tassel hook 200.
  • the tassel auxiliary part 100 shown in Fig. 5 is provided with the tubular hiding member 152 for covering a looped tassel cord, the tassel auxiliary part 100 alone can be locked to the tassel hook 200. According to this configuration, it is possible to prevent a dweller from mistakenly hooking the looped tassel cord to which the tassel auxiliary part 100 is connected, on the tassel hook 200 and thus to effectively increase the safety.
  • Fig. 6 is a diagram showing a modification 4 of the present embodiment in which a fall prevention collar 160 is disposed on a tassel auxiliary part 100. Since the tassel auxiliary part 100 further includes the fall prevention means (e.g., the fall prevention collar 160) that after a first coupling member 115 and a second coupling member 116 forming a separation part are decoupled, prevents the tassel auxiliary part 100 from falling from a tassel hook (a section of a shaft 144 of the tassel hook is shown), the decoupled members can be easily restored to their original state.
  • the fall prevention means e.g., the fall prevention collar 160
  • Figs. 7(a) is a diagram showing an appearance of an unlooped (clip-type) tassel auxiliary part 130 of a second embodiment.
  • Figs. 7(b) and (c) are diagrams showing the internal structure and operation of the clip-type tassel auxiliary part 130 of the second embodiment.
  • a curtain accessory 1000 of the present embodiment is the tassel auxiliary part 130.
  • a coupling mechanism of the tassel auxiliary part 130 includes a separation part (e.g., a first clip 132 and a second clip 134 shown in Fig. 7 ) that separates the tassel auxiliary part 130 from an adjacent another member (e.g., the shaft 144 of the tassel hook whose section is shown in Figs. 7(b) and 7(c) ) by a pulling force. Note that in Figs. 7(b) to 7(c) , the upper and lower parts of a base 142 of the tassel hook are omitted.
  • the tassel auxiliary part 130 includes an insertion part 138 into which a looped tassel cord 150 of a tassel 300 can be inserted.
  • the separation part of the tassel auxiliary part 130 includes clips (first clip 132 and second clip 134) for sandwiching the shaft 144 of the tassel hook [whose sections are shown in Fig. 7(b) and 7(c) ].
  • the two clips, 132 and 134 are coupled together so as to be relatively rotatable about a rotating shaft 136 (metal pin inserted).
  • the tassel auxiliary part 130 includes a cam mechanism that causes the two clips, 132 and 134, to continue to hold the tassel hook 200 (a section of the shaft 144 of the tassel hook is shown), as shown in Fig. 7(b) , as well as elastically deforms the clips 132 and 134 so that the clips can be detached from the tassel hook 200 by a predetermined load, as shown in Fig. 7(c) .
  • This cam mechanism includes a cam 146 disposed on an end adjacent to the rotating shaft 136, of the first clip 132 and a wall 148 disposed in a position in contact with the cam 146, of the second clip 134. According to this cam mechanism, the cam 146 of the first clip 132 opens while pressing the wall 148 of the second clip 134. Note that the first clip 132 and second clip 134 themselves also have some elasticity.
  • the first clip 132 and second clip 134 are provided with guide edges 140a and 140b, respectively. Since the shaft 144 of the tassel hook is guided by the guide edges 140a and 140b, the shaft 144 can be easily inserted into the inside of the clips even manually when restoring the tassel auxiliary part 130 to its original state.
  • a smaller slit than the tassel cord 150 may be formed in the insertion part 138 so that the looped tassel cord 150 can be inserted into the insertion part 138 through the slit from a side of the tassel auxiliary part 130.
  • This configuration is advantageous in that the tassel auxiliary part 130 can be easily attached to an existing tassel.
  • the curtain accessory 1000 of the present embodiment may be the tassel 300 (not shown in Fig. 7 ).
  • the coupling mechanism may be a clip structure (a separation part including a first clip 132 and a second clip 134) disposed on one edge of the tassel 300.
  • This clip structure also can produce effects similar to those of the clip structure disposed on the tassel auxiliary part 130.
  • Fig. 8(a) shows a tape 154 provided with two tassel cords 150 to be sewed on both edges of a tassel 300, as a curtain accessory 1000 of a third embodiment.
  • the string of one of the two tassel cords 150 is separated, and the separated portions are jointed together by a tassel auxiliary part 100.
  • the tape 154 is separated between the two tassel cords and then the tassel cords are sewed on both edges of the tassel 300; respective base portions of the two tassel cords 150 disposed on the tape 154 are woven into the tape 154; while one of the two tassel cords 150 is not separated at any midpoint thereof, the other tassel cord 150 is separated at a midpoint thereof; and a separation part 16 is inserted between the separated portions of the tassel cord 150.

  • the displacement mechanism 800 is configured to, when the load applied to the hooking part 206 through the tassel cord 310b exceeds the predetermined value (e.g., 2kgf), increase the angle of the hinge 235 so that the tassel cord 310b slides in a movement direction 900 of the tassel cord and falls, as shown in Fig. 30(f) . Since an upper side 205 of the hinge 235 has no recess in the displaced state, the tassel cord 310b is prevented from being caught on a recess and thus failing to fall.
  • the predetermined value e.g. 2kgf
  • Fig. 31 includes diagrams showing an aspect in which the tassel hook 200 of the present embodiment is used with an existing tassel 300. For example, if a dweller is caught on the tassel 300 with one looped tassel cord, 310b, hooked on the hooking part 206 of the tassel hook 200, a pulling force 500 is applied to the tassel cord 310b disposed on one edge of the tassel 300, as shown in Fig. 31(a) .
  • the structure of the tassel hook 200 is displaced (in the displacement direction 702), as shown in Fig. 31(b) .
  • the tassel 300 is unlocked (in the unlocking direction 704), and the tassel 300 falls toward the floor.
  • the structure of the tassel hook 200 is restored to the original state by the energizing force of the elastic means (flat spring 229), allowing the tassel hook 200 to hold the tassel 300 again.
  • Figs. 32 and 33 are structure diagrams showing a hinge-type displacement mechanism 800 of a tassel hook 200 of a modification of the present embodiment.
  • a torsion spring is used as elastic means in place of the flat spring 229.
  • the torsion spring is also called a coil spring and includes a coil 236 and two arms 234a and 234b.
  • the coil 236 of the torsion spring is wound about a rotating shaft 238 disposed in the center of a hinge 235.
  • the arm 234b of the torsion spring is housed in an arm housing space 232b disposed in a hooking part.
  • the arm 234a of the torsion spring is housed in an arm housing space 232a disposed in a protruding shaft 204.
  • a predetermined value e.g. 2kgf
  • the angle of the hinge 235 is increased, and the tassel cord 310b slides in a tassel cord movement direction 900 and falls, as shown in a side sectional view of Fig. 32(d) and a front view of Fig. 32(e) . Since an upper side 205 of the hinge 235 has no recess in the displaced state, the tassel cord 310b is prevented from being caught on a recess and thus failing to fall.
  • fitting structure of the separation part 114 used in the coupling mechanism some typical examples have been described as the fitting structure of the separation part 114 used in the coupling mechanism.
  • those fitting structures are not limiting, and any type of known fitting structure may be used.
  • various types of fitting structures described in WO2011/136235 can be suitably used. Even when those fitting structures are used, the safety of a curtain accessory can be improved as in the embodiments.
  • the tassel hook 200 is separated into multiple portions by a pulling force
  • the tassel auxiliary part 100 or tassel 300 may be separated into multiple portions.
  • the looped cord 111 of the tassel auxiliary part 100 shown in Fig. 1(a) may be a cord that is a single cord around the center but forms loops on both sides and is provided with a separation part 114 disposed at the center and separated into multiple portions by a pulling force.
  • the tassel cord 310 of the string tassel 300 including the decoration member 306 shown in Fig. 13(b) may be a cord that is a single cord in the through hole of the decoration member 306 and is provided with a separation part 114 disposed in the through hole and separated into multiple portions by a pulling force.
  • the coupling mechanism is configured to be decoupled if the load applied to the tassel 300 exceeds 2kgf, which is the predetermined value
  • the coupling mechanism may be configured to be decoupled if the load applied to the tassel 300 is equal to or more than one of 2kgf, 2.5kgf, 3kgf, 3.5kgf, 4kgf, 4.5kgf, and 5kgf, or exceeds one thereof.
