  The intended purpose of the present invention is to completely eliminate the situation in which a hand can be pinched by a fallen movable shoji. The second purpose is to facilitate combination and mounting by rationally combining the constituent members.

  The movable shoji brake device of the present invention is supported by a side end portion of a movable shoji that moves up and down via a suspension member via a horizontal axis, and the vertical frame direction of the window at each of the upper and lower ends of the base portion 25a. An engaging arm member 25 having engaging portions 25b and 25c projecting to the center, and a central portion is wound around the horizontal axis, one end portion being the side end portion, and the other end portion being the engaging portion. The suspension member includes a spring member 31 that presses against each of the arm members and constantly urges the engagement arm member in the engagement direction, and a receiving member Y fixedly provided at a predetermined position of the vertical frame of the window. In the normal state where the tension is applied to the engaging portion 25c on the lower end side, the engaging arm member 25 is separated from the inner wall surface of the vertical frame against the spring force of the spring member. On the other hand, in the case of an emergency when the suspension material is cut, the horizontal axis is supported by the spring force of the spring member. Characterized in that it is received in the locking state by a predetermined amount of rotation from above the engaging portion 25b is receiving member Y of the upper end as a fulcrum.

(A) The situation where a hand is pinched by the fallen movable shoji can be eliminated completely.
(B) Since the respective constituent members are rationally combined, combination and mounting are easy.

  The best mode (first embodiment) for carrying out the present invention shown in FIGS. 1 to 5 will be described below.

(1) Environment for Implementing the Invention FIG. 1 is a schematic explanatory diagram showing the environment for implementing the invention. Since the movable shoji brake device X is the same on the left and right, only one (left side) configuration is specifically shown in the drawing. Here, reference is made to the environmental member with reference to FIG. In FIG. 1, 1 is a raising / lowering window. The raising / lowering window 1 is provided with an inner shoji 3 and a fixed outer shoji 4 which are movable up and down along the vertical frames 2A and 2B constituting the window in the internal space of the window frame 2 configured in a rectangular frame shape. .

  In addition, a pair of right and left winding means, for example, spiral spring type balancer devices 5 and 5 are arranged on the upper portions of the vertical frames 2A and 2B. From these winding means 5 and 5, for example, to the hanging drop point of the upper frame, respectively. Lower ends 7a, 7a of a pair of left and right suspension members (for example, a wire, a rope, etc.) 7 and 7 fed out through the arranged guide pulleys 6 and 6 are engaged arm members 25 constituting the brake device X. It is directly attached to the engaging portion 25c on the lower end side.

  2C is a lower horizontal frame of the vertical frame, and FIG. 1 shows a state in which a gap 8 remains between the horizontal frame 2C and the lower end portion 3b of the movable shoji 3 (the movable shoji 3 is slightly raised upward). State).

  Further, the spiral spring type balancer device 5 keeps a mechanically balanced relationship with the weight of the inner shoji 3 by an installed spiral spring so that the inner shoji 3 can be easily opened and closed with a small force. It is possible to stop at the height position. Further, the outer shoji 4 can be similarly suspended as a movable shoji that can be opened and closed in the vertical direction by using a double balancer (not shown) disposed on the upper frame.

(2) Details of Drawings Regarding Configuration Specific requirements of the present invention will be sequentially described with reference to FIGS. FIG. 2 shows a side end (vertical rod) 3a of the movable shoji 3 located in the guide portion 2a of the vertical frame 2A and a receiving member Y fixed at a predetermined position of the vertical frame 2A. In the present embodiment, the main constituent members of the brake device X are incorporated into the side end portion 3a of the movable shoji 3 via a case-like support member 15. That is, the unit type brake device X is fitted and fixed in the side end portion (vertical rod) 3 a of the movable shoji 3 through the mounting opening 11.

  On the other hand, when the receiving member Y on the side of the vertical frame 2A receives the engaging arm member 25 on the side of the movable obstacle 3 that has fallen, the movable obstacle 3 is not completely closed. In addition, when the movable shoji 3 is dropped, the receiving member Y positions the brake device X on the movable shoji 3 side so that the finger is not caught between the lower end 3b of the movable shoji 3 and the lower horizontal frame 2C. In consideration, it is fixed to the inner wall surface a of the vertical frame 2A.

  FIG. 3 is a perspective view showing a part of the vertical frame 2A and the receiving member Y together with the main part of the brake device X disassembled. FIG. 4 shows a normal time, while FIG. 5 shows an emergency when the suspension member 7 is cut.

  The engagement arm member 25 of the brake device X is in a vertical state in a normal state (normal state), and on the other hand, in an emergency, the engagement arm member 25 is rotated by a predetermined amount and tilted. The receiving member Y is received in a locked state. In the latter case, the movable shoji 3 stops with a required gap (a space where no finger can be caught) 8 left between the lower end 3b and the horizontal frame 2C of the window.

(3) Specific configuration The explanation of detailed matters is omitted. Here, in particular, with reference to FIGS. 3 and 4, a specific configuration of a main part of the brake device X will be described. An opening 11 for mounting a support member is formed in the vertical direction on the side surface of the side end of the movable shoji 3 (for example, the lower end of the side end). At the upper and lower end portions that form the mounting opening 11, for example, a step is formed in the inner direction, and a female screw portion 12 for the fixing tool 13 is formed. In the present embodiment, the support member 15 that forms the brake device X is a separate member from the side end portion 3 a of the movable shoji 3.

The support member 15 is externally formed, for example, in the shape of a trolley, and includes a case portion 15a fitted into the mounting opening 11, and upper and lower end plate portions 15b extending in an ear shape from the opening end of the case portion 15a. It consists of.
A pair of shaft holes 16 are formed in the central portion of the opposing side wall of the case portion 15a. Further, the end plate portion 15b is formed with a mounting hole 17 for the fixing tool 13. Further, an escape notch 18 is formed in the vertical bottom wall of the case portion 15a from the portion near the center to the lower end.

  Reference numeral 19 denotes a front plate of the support member 15. The front plate 19 is formed in a vertically long shape corresponding to the form of the support member 15, and through holes 20 are formed in the upper and lower end portions respectively to match the end plate portion 15 b and the female screw portion 12 described above. .

  Therefore, as shown in FIG. 4, the support member 15 and the front plate 19 of this embodiment are fixedly fitted to the mounting opening 11 of the side end portion 3 a via the plurality of fixing tools 13. Desirably, as shown in FIG. 4, the front plate 19 and the side surface of the side end portion 3a are designed to be flush with each other.

  By the way, the front plate 19 has two windows 21 and 22 through a partition wall 19a having a function of supporting the central portion. In other words, reference numeral 21 is an upper window for the engaging portion 25b on the upper end side of the engaging arm member 25, while reference numeral 22 is a lower window for the engaging portion 25c on the lower end side of the engaging arm member 25. is there.

  Here, the configuration of the engagement arm member 25 will be described. The engaging arm member 25 is formed, for example, in a U-shaped end surface having a vertical base portion 25a and upper and lower engaging portions 25b and 25c that are provided in the lateral direction at the end of the base portion 25a. The side end portion 3a is supported directly or indirectly via the horizontal shaft 26. The end face shape of the engagement arm member 25 is an arbitrary matter.

  Thus, a pair of shaft holes 27 for the horizontal shaft (fixed support shaft) 26 are formed in the central portion of the vertical base portion 25a. The engagement portion 25b on the upper end side is formed in an appropriate shape such as a fingertip shape or a hook shape in consideration of toughness and the certainty of engagement with the receiving member Y. Further, the engagement portion 25c on the lower end side extends slightly toward the vertical frame side than the engagement portion 25b on the upper end portion side, and the lower end portion 7a of the suspension member 7 is directly connected (engaged) to the tip portion thereof. Also included).

  Thus, the engaging arm member 25 of the present embodiment is pivotally supported by the case-like support member 15 through the horizontal shaft 26 at the center, and in the normal state shown in FIG. 4, the back surface of the vertical base portion 25a. Is supported by the case portion 15a of the support member 15, or the upper surface of the engagement portion 25c on the lower end side is supported by the lower edge of the partition wall 19a of the front plate 19, so that the amount of rotation does not rotate more than necessary. Is regulated.

  Since the engaging arm member 25 is normally supported by the support member 15 in the normal state, the upper and lower arm-shaped engaging portions 25b and 25c are respectively provided from the upper window 21 and the lower window 22 of the front plate 19. It protrudes toward the vertical frame direction 2A in a substantially horizontal state.

  Next, a central portion 31 a is wound around the horizontal shaft 26, and one end portion 31 b is pressed against the inner surface of the front plate 19, while the other end portion 31 c is the base portion 25 a of the engaging arm member 25. It is a spring member that presses against the inner surface of the lateral recess 30 and constantly urges the engagement arm member 25 in the engagement direction.

  Lastly, the receiving member Y has an end face angle shape, a hook shape, a hook shape, a bowl shape, and a trapezoidal shape that are fixed to protrude at an appropriate position on the inner wall surface a of the guide portion 2a of the vertical frame 2A (2B) of the window 2. It is a receiving piece formed in an appropriate shape such as.

  The receiving member Y of the present embodiment is formed in an end face angle shape so as to engage with the engaging arm member 25 "tightly". Note that an elastic body (rubber sheet) is attached to the receiving surface of the receiving piece Y, although not particularly illustrated.

(4) Action Since the engaging arm member 25 is pivotally supported via the support member 15 incorporated in the side end portion 3a of the movable shoji 3, when the movable shoji 3 moves up and down, naturally, the vertical frame 2A ( 2B) is moved up and down in the guide portion 2a. Further, since the engaging arm member 25 is biased by the spring member 31 in the direction of frictional engagement with the guide portion 2a of the vertical frame 2A (2B), when the suspension member is relaxed, the spring force of the spring member 31 causes , Rotate in the engagement direction. At this time, the lower end portion of the engagement arm member 25 enters the relief cutout 18 of the support member 15, and the engagement arm member 25 is tilted.

  Therefore, when the tension of the suspension member 7 is applied to the engagement protrusion 25 c on the lower end side of the engagement arm member 25 in the normal time, the engagement arm member 25 resists the spring force of the spring member 31. It is supported in a substantially vertical state via a support member 15 on the side end 3a of the movable shoji 3 while being separated from the inner wall surface a of the vertical frame 2A.

  In other words, the engagement protrusion 25b on the upper end side of the engagement arm member 25 is held at a position away from the inner wall surface a of the guide portion 2a of the vertical frame. Therefore, the left and right brake devices X do not brake the movable shoji 3.

  On the other hand, in the case of an emergency when the suspension member 7 is cut, the engagement arm member 25 is instantaneously moved from above to the engagement direction by the spring force of the spring member 31 with the horizontal shaft 26 at the center as a fulcrum. Rotate.

  In other words, the engaging arm member 25 rotates about a required amount as if the upper arm is swung down from above with the horizontal shaft 26 as a fulcrum, and is rotationally displaced into a state where it can engage with the receiving member Y. Then, at the same time when the movable shoji 3 is dropped, the tip of the upper arm (engagement portion) 25b of the engagement arm member 25 is frictionally engaged with the inner wall surface a of the guide portion 2a, and the movable shoji 3 is completely closed before the predetermined position. Thus, as shown in FIG. 5, the receiving member Y is received in a locked state. Therefore, in this embodiment, the upper arm (engagement portion) 25b of the engagement arm member 25 on the movable obstacle side passes through the receiving member Y, and the movable obstacle 3 is not completely closed.

  In this column, reference is made to the design change of the unit type first embodiment. First, FIGS. 6 to 8 show an example in which the design of the movable shoji 3A and the support member 15A is changed. In the first embodiment described above, the trowel-shaped support member fitted and fixed to the side opening (vertical rod) 3a of the movable shoji 3 and the mounting opening 11 formed in the side edge 3a via the fixing tool 13. 15 is a separate member.

  However, in the design modification examples shown in FIGS. 6 to 7 (hereinafter referred to as “second embodiment”), the side end 3a itself is not separated from the side end 3a and the side end 3a itself of the movable shoji 3 itself. A support member 15A is formed on the substrate. In other words, when the side end portion (vertical rod) 3a is formed, the support member (support frame portion) 15A for incorporating the engaging arm member 25, the horizontal shaft 26 and the spring member 31 in advance is used as the side end portion (vertical rod). ) Integrally molded to 3a.

  By the way, in the second embodiment, since the support member 15A is a part of the side end portion (vertical rod) 3a of the movable shoji 3, for example, a part of the side surface of the side end portion (vertical rod) 3a is the front. The upper and lower windows 21 and 22 are respectively formed on the front plate (front) 19A via a partition wall 19a.

  Further, a hole formed at an appropriate location on the side surface on the indoor side orthogonal to the front plate 19A becomes a shaft hole (support hole) 16A for inserting the horizontal shaft 26. Further, as shown in FIG. 7, a portion connected in an angle cross-sectional shape (L shape) from the upper edge of the upper window 21 of the front plate 19 </ b> A to the inside corresponds to a part of the case portion 15 a.

  Therefore, in the second embodiment, “How to incorporate the engaging arm member 25, the horizontal shaft 26, and the spring member 31 into the support member (support frame portion) 15A of the side end portion (vertical rod) 3a”. However, for example, the engagement arm member 25 and the like are incorporated into the side end portion (vertical rod) 3a in the order of A process to E process shown in FIG.

  First, A is a spring member temporary mounting step for temporarily mounting the spring member 31 to the engaging arm member 25. In the spring member temporary mounting step A, a temporary fixing pin 41 separate from the horizontal shaft 26A is used. The temporary fixing pin 41 inserted into the shaft hole 27 is shorter than the horizontal axis A26. For example, the length is about a quarter of the horizontal axis 26A. Further, the temporary fixing pin 41 is a solid column (this embodiment) or a pipe-like column having an engagement hole that is integrally engaged with the insertion tip of the horizontal shaft 26A. In short, the spring member 31 is inserted into the lateral recess 30 of the engaging arm member 25 before the engaging arm member 25 is fitted into the supporting member (supporting frame portion) 15A of the side end (vertical rod) 3a. Temporary mounting is performed via the temporary fixing pin 41.

  Next, B is a hanging material connecting portion attaching step for attaching the hanging material connecting portion 42 to the distal end portion of the engaging portion 25c on the lower end side of the engaging arm member 25. In this hanging material connecting portion mounting step B, a hanging material connecting portion (suspending material engaging portion) 42 having a circumferential groove 43 is screwed to a female thread portion formed at the tip of the engaging portion 25c. In addition, since the magnitude | size of this suspension material connection part 42 can be formed arbitrarily, the last process E mentioned later may be sufficient.

  Next, C is an engagement arm member insertion step in which the engagement arm member 25 including the spring member 31 and the suspension member connecting portion 42 is inserted from the lower window 22. In this engagement arm member insertion step C, the engagement portion 25 c on the lower end side is grasped with a finger, and the engagement portion 25 b on the upper end side is inserted into the lower window 22.

  Next, D is a shaft hole positioning step in which the engaging arm member 25 and the temporary fixing pin 41 (shaft hole 27) are aligned with the shaft hole 16A of the support member (support frame portion) 15A. This shaft hole alignment step D is performed by looking into the shaft hole 16A of the side end 3a from the indoor side.

  Finally, E inserts the horizontal shaft 26A from the shaft hole 16A of the side end portion 3a, and passes through the shaft hole 27 of the engagement arm member 25 and the central portion of the spring member 31, thereby causing the horizontal shaft 26A to pass through. This is an engaging arm member pivoting process in which a side shaft 3a is mounted on the side end 3a.

  In the present embodiment, since the temporary fixing pin 41 is solid, the temporary fixing pin 41 falls off the other side surface of the engaging arm member 25 due to the insertion action on the horizontal shaft 26A. In the engaging arm member pivoting step E, as described above, the suspension member connecting portion 42 may be retrofitted.

  Therefore, the engagement arm member 25 of the present invention is directly or indirectly pivotally supported on the side end portion 3a of the movable shoji 3 that moves up and down via the suspension member 7 via the horizontal axis (26, 26A), and The upper and lower ends of the base portion 25a only need to have engaging portions 25b and 25c that protrude in the vertical frame direction 2A (2B) of the window. In an emergency, the spring force of the spring member 31 causes the upper arm engaging portion 25b to rotate and displace by a predetermined amount relative to the inner wall surface a of the vertical frame.

  Next, an example in which the design of the receiving member Y is changed will be described. The receiving member Y has an end face angle shape, a hook shape, a hook shape, a bowl shape, a trapezoidal shape, etc. fixed so as to protrude at an appropriate position on the inner wall surface a of the guide portion 2a of the vertical frame 2A (2B) of the window. Although it has been described that the receiving piece is formed in an appropriate shape, a female engaging portion such as an engaging groove or an engaging hole may be used. When this female engagement portion is mentioned, since there is no limit, one example is simply shown in FIG.

  FIG. 9 shows that the receiving member Y1 may be formed directly or indirectly on the guide portion 2a of the vertical frame 2A (2B) of the window, or one or more female engaging portions y. It is a thing.

  The present invention is mainly used in the locksmith and joinery industries.
