Definitions

  • the device comprises a stopper roller which is designed to keep follow-up contact with the pull cords and which is rotatably supported by a guide member on a floating axis in perpendicular to the direction of routing of the pull cords, and a stopper case which supports the stopper roller and which has on its bottom surface a rotating contact face with the stopper roller.
  • a loop-like guide groove is formed on the side walls of the stopper case above the rotating contact face.
  • a stopper pin is disposed a predetermined distance apart from the guide groove and between the side walls. Also disposed is a restraint contact portion which is extended in parallel with the floating axis and which is radially apart from the guide member on the floating axis beyond the radius of the stopper roller.
  • Fig.7 is a top view showing that a pin is engaged with a position A in the guide groove of the switch member.
  • Fig.12 is a perspective view showing the pull cord stopper device of Fig.11 with its pressure member opened.
  • Fig.16 is a cross-sectional view showing another state of the pull cord stopper device that sets the pull cords free to move.
  • Fig.25 is a cross-sectional view showing another state of the pull cord stopper device that sets the pull cords free to move.
  • Fig.32 is a horizontal cross-sectional view showing the interior of the head box.
  • Fig.3 is a perspective view showing an assembled pull cord stopper device 20, and Fig.4 is a cross-sectional view taken along line 4-4 in Fig.3.
  • the slidable block 32 is inserted into the stopper case under its comb portion 40 in a manner that the arms 48 of the slidable block 32 come toward the knurled portion 42.
  • the pinch roller 30 is mounted on the arms 48 with its projections 44 rotatably received at the through-holes 50.
  • the pinch roller 30 is engaged with the stopper case 28 with its knurled portion 42 meshed with the circumferential sawteeth on the pinch roller 30.
  • the pull cord stopper device 20 can switch between engagement and release of engagement of the pull cords 16 depending on how many times the control string has been pulled before the current pulling.
  • the slidable block 66 comprises a support 78 that supports the switch member 68 in a manner that allows the switch member 68 to move in a direction perpendicular to the direction of the movement of the slidable block 66, arm portions 80 that rotatably support the pinch roller 64, and a contact portion 81 which transversely connects the ends of the arm portions 80 and which has a curved face on its underside so that the pull cords 16 are guided thereunder.
  • the slidable block 66 is mounted inside the stopper case 62 in a manner that its support 78 comes to the pin 76 side and its arm portions 80 come to the knurled portion 74 side.
  • the slidable block 98 comprises a support 114 that supports the switch member 98 in a manner that allows the switch member 98 to move in a direction transverse to the direction of the movement of the slidable block 96, arm portions 116 for rotatably supporting the pinch roller 94, and a contact portion 118 which transversely connects the ends of the arm portions 116 and which has a curved face on its underside so that the pull cords 16 are guided thereunder.
  • the slidable block 96 is mounted inside the stopper case 92 in a manner that its support 114 comes to the pin 102 side and its arm portions 116 come to the knurled portion 106 side.
  • the pressure member 100 in cooperation with the pinch roller 94 pinches the pull cords 16 to restrain their movement.
  • the pull cords 16 are introduced by the comb portion side into the stopper case 92 by routing each cord through the corresponding recess of the comb portion, routed on the top surface of the stopper case 92 and the pinch roller 94, and then under the contact portion 118 along its curved face, and are delivered out of the stopper case 92 at a slight upward inclination.
  • the slidable block 96 of the pull cord stopper device 90 is kept more toward the left as Fig.23 with the pin 102 restrained by a position W of the guide groove 120 of the switch member 98 in Fig.27.
  • the pinch roller 94 is positioned at the left end of the knurled portion 106 as in Fig.23, and pinches the pull cords 16 against the pressure member 100.
  • the pull cords 16 move leftward in Fig.24 because of the mass of the bottom weight 14.
  • the contact portion 118 provides a slight forced contact on its right half of its curved face opposite the pinch roller 94 side in Fig.24. This contact provides friction with the pull cords 16, causing the contact portion 118 to move leftward.
  • the pinch roller 94 while idly rotating, moves leftward along with the slidable block 96 in Fig.24.
  • the switch member 98 moves leftward in Fig.24 and at the same time approaches the reader in perpendicular to the plane of Fig.24 as well, until the pin 102 goes over the portion N in the guide groove 120 and reaches a position Y in the portion O in the guide groove 120 in Fig.29.
  • the pin 102 reaches the position Y of the guide groove 120, the leftward movement of the switch member 98 is restrained in Fig.24, and the slidable block 96 cannot continue its leftward movement any more in Fig.24.
  • the slidable block 96 and the pinch roller 94 stop as shown in Fig.25.
  • the pressure member is detachably mounted into the stopper case, and thus routing the pull cords is easy.
  • the stopper case 230 has longitudinally midway on its inner bottom surface a knurled portion 242 where transversely extending sawtooth projection, if viewed in a longitudinal cross-section, is repeated longitudinally in a sawtooth-like manner.
  • the knurled portion 242 is meshed with the sawtooth circumference of the pinch roller 232.
  • the stopper case 230 has on its bottom surface a cutout 244 that extends from the end of the knurled portion 242 to one end of the stopper case 230.
  • the stopper case 230 is provided with a pin 246 that is projected downward as shown in Fig.31.
  • the rightward movement of the slidable block 234 causes the switch member 236 to move rightward until the pin 246 reaches the predetermined position in the guide groove 254.
  • the pin 246 reaches the predetermined position in the guide groove 254.
  • the slidable block 234 cannot move any more rightward as shown in Fig.31.
  • the slidable block 234 and the pinch roller 232 stop.
  • the pull cords 216 are not pinched between the pinch roller 232 and the pressure member 238, the control string 24 can be continuously pulled downward.
  • the pull cords 216 move leftward in Fig.31 because of the mass of the bottom weight 14.
  • the contact portion 252 provides a slight forced contact on its right half of its curved face opposite the pinch roller 232 side. This contact provides friction with the pull cords 216, causing the contact portion 252 to move leftward.
  • the pinch roller 232 while idly rotating, moves leftward along with the slidable block 234.
  • the switch member 236 moves leftward until the pin 246 reaches to a predetermined position in the guide groove 254.
  • a plurality of pull cords 216 sliding in the head box 210 are separated one from another through the comb portion 240 in the stopper device 220, routed along on the pinch roller 232 and under the contact portion 252, delivered out of the stopper device 220, and again separated one from another through the comb member 256, guided by the guide roller 258 toward the pull cord exit opening 228, and then routed out of the head box 210 through the exit opening 228.
  • the screen 212 is thus raised.
  • the pull cords 216 move leftward in Fig.31 because of the mass of the bottom weight 14.
  • the contact portion 252 moves leftward in Fig.31, and thus the pinch roller 232, while rotating idly, moves leftward along with the slidable block 234 in Fig.31.
  • the switch member 236 moves leftward until the pin 246 reaches a predetermined position in the guide groove 254.
  • the pinch roller 232 while rotating idly in the space of the cutout 244, moves leftward and reaches the knurled portion 242. Thereafter, the pinch roller 232 continues to move leftward under the guiding of the knurled portion 242 in Fig.31.
  • Fig.33 shows a fifth embodiment of the present invention.
  • the fifth embodiment is identical to the fourth embodiment in construction except that the comb member 256 is removed from between the pull cord stopper device 220 and the pull cord exit opening 228 and that the pull cord stopper device 220 is installed closer to the pull cord opening 228.
  • This embodiment is particularly useful when the number of pull cords 216 is small. When the number of pull cords 216 is small, the possibility of tangling is accordingly small. If tangled, the cords may be relatively rapidly disentangled. Even if the stopper device 220 is mounted close to the pull cord exit opening 228, the tangled portion of the cords 216 is disentangled before it reaches the pull cord stopper device 220.
  • the operation of the present embodiment is identical to the fourth embodiment except the comb member 256.
