Description

  The present invention relates to a face grid installed outside the window of a building such as a residence for crime prevention. More specifically, in the event of an emergency such as a fire, a part of the face grid can be opened to escape to the outside. It relates to an open-type surface lattice.

Conventionally, some open-type surface lattices that can open a part of the surface lattice in an emergency such as a fire have been proposed (see, for example, Patent Document 1). However, the conventional open-type surface grid has a difficulty in that an intruder can easily open the surface grid by operating the opening operation unit from the outside when the window is opened.

The slider 5 has an opening 511 facing the engagement hole 121 of the lower lateral lattice 12 at the engagement position, and a slit 512 facing the engagement hole 121 at the release position. In addition, the vertical portion 52 of the slider 5 is formed with a long hole 521 to which the crank arm 63 of the operating means 6 is connected.

  As shown in FIG. 2, the upper engaging member 3 that engages with the upper horizontal lattice 11 is rivet-fixed near the upper end of the back surface of the movable vertical lattice 22. The upper engaging member 3 includes a claw portion 31, and a concave portion 32 opened upward is formed between the claw portion 31 and the back surface of the movable vertical lattice 22. An elastic member 33 made of a leaf spring is spot welded to the front surface of the claw portion 31. As shown in FIG. 2A, the claw portion 31 of the upper engaging member 3 is inserted into the engaging hole 111 of the upper horizontal lattice 11 from below, and the upper horizontal member is interposed between the elastic member 33 and the back surface of the movable vertical lattice 22. By sandwiching the vertical surface of the lattice 11, the upper engaging member 3 is engaged with the upper lateral lattice 11.

  A lower engaging member 4 that engages with the slider 5 in the lower horizontal lattice 12 is rivet-fixed near the lower end of the back surface of the movable vertical lattice 22. The lower engaging member 4 includes a claw portion 41, and a concave portion 42 opened upward is formed between the claw portion 41 and the back surface of the movable vertical grid 22. An elastic member 43 made of a leaf spring is spot welded to the front surface of the claw portion 41. As shown in FIG. 2A, the claw portion 41 of the lower engagement member 4 is inserted into the engagement hole 121 of the lower horizontal lattice 12 from below, and the lower portion of the elastic member 43 is placed on the edge of the slit 512 of the slider 5. , The lower engaging member 4 is engaged and supported by the slider 5. As shown in FIG. 2B, if the slider 5 is moved to a release position where the opening 511 faces the engagement hole 121 of the lower horizontal lattice 12, the lower engagement member 4 and the slider 5 are moved. And the movable vertical lattice 22 loses support by the slider 5, the claw portion 41 of the lower engagement member 4 comes out of the opening 511 and the engagement hole 121, and the movable vertical lattice 22 is It falls by its own weight.

  A hook member 23 is rivet-fixed above the upper engagement member 3 on the back surface of the movable vertical lattice 22. As shown in FIG. 2 (b), when the movable vertical lattice 22 falls when the lower engagement member 4 and the slider 5 are disengaged, the hook member 23 is caught on the upper portion of the upper horizontal lattice 11. In this state, the movable vertical lattice 22 is moved along the longitudinal direction of the upper lateral lattice 11 (see FIG. 9).

  As shown in the exploded perspective view of FIG. 3, the operating means 6 for moving the slider 5 includes a bearing member 61 to be fixed to the lower horizontal lattice 12, a shaft member 62 supported by the bearing member 61, a shaft A crank arm 63 provided at one end of the member 62, an operation rod 64 pivotally supported at the other end of the shaft member 62, and a handle 65 pivotally supported at the tip of the operation rod 64 It is composed of

  A protrusion 631 is provided at the tip of the crank arm 63, and the protrusion 631 is fitted in the long hole 521 of the slider 5. A piece member 641 is provided at the base of the operation rod 64, and the piece member 641 is inserted into a recess 621 formed in the shaft member 62 and is pivotally supported by a pin 622. Thus, the operating rod 64 is tilted substantially parallel to the longitudinal direction of the lower lateral lattice 12 and is accommodated in the lower lateral lattice 12, and the operating rod 64 is substantially orthogonal to the longitudinal direction of the lower lateral lattice 12. Thus, it can be tilted between the operation position that is raised and protrudes indoors. If the operating rod 64 is rotated from the stowed position to the operating position and then the operating rod 64 is rotated, the slider 5 can be reciprocated via the crank mechanism including the shaft member 62 and the crank arm 63, as described above. Furthermore, the engagement of the movable vertical lattice 22 with respect to the slider 5 can be released.

  The bearing member 61 has a notch 612 formed therein, and the operation rod 64 in the storage position is pivotally supported by the shaft member 62 with the piece member 641 inserted into the notch 612. Therefore, the operating rod 64 cannot be rotated unless the operating rod 64 is raised to the operating position. The handle 65 can be tilted between a storage position that is tilted substantially parallel to the longitudinal direction of the operation rod 64 and an operation position that is lifted so as to be substantially orthogonal to the longitudinal direction of the operation rod 64. . If the handle 65 raised at the operation position is gripped, the operation rod 64 can be easily rotated.

  Further, as shown in FIGS. 3 and 4, the operation rod 64 is configured to be extendable and contractable by two hollow rod parts 642 and 643. A small-diameter rod part 643 is removably inserted into the large-diameter rod part 642, and the operating rod 64 can be extended by pulling out the small-diameter rod part 643 from the large-diameter rod part 642. As shown in FIG. 4, the piece member 641 is fixed to the base of the large-diameter rod part 642, and the outer cylindrical cap 644 is fixed to the tip. An inner cylindrical cap 645 is fixed to the base of the small-diameter rod part 643, and the handle 65 is pivotally supported by a pin 651 at the tip. When the small-diameter rod part 643 is pulled out to the maximum, the outer peripheral part of the inner cylindrical cap 645 contacts the inner peripheral part of the outer cylindrical cap 644.

  As shown in FIG. 5, the lock unit 7 that restricts the operation of the operation unit 6 includes a key member 71 that is inserted between the bearing member 61 and the shaft member 62 of the operation unit 6. A bearing-side key groove 610 is formed on the inner peripheral portion of the bearing member 61, and an axial-side key groove 620 is formed on the outer peripheral portion of the shaft member 62. A substantially prismatic key is formed between the key grooves 610 and 620. The member 71 is inserted. As shown in FIG. 5A, the shaft member 62 cannot be rotated with respect to the bearing member 61 in a state where the key member 71 is inserted between the key grooves 610 and 620. Therefore, even if the operating rod 64 is raised from the storage position to the operating position, the operating rod 64 cannot be rotated. On the other hand, as shown in FIG. 5B, in a state where the key member 71 is removed from between the key grooves 610 and 620, the operation rod 64 is rotated to rotate the shaft member 62 and illustrated via the crank arm 63. The slider 5 not to be moved can be moved.

  As shown in FIG. 4, the release means 8 for releasing the lock means 7 is constituted by a flexible string-like member 81 made of a wire drawn through a hollow operation rod 64 of the operation means 6. Yes. The base end of the string-like member 81 is fixed to the key member 71 through the through hole 640 formed in the piece member 641 via the caulking member 82, and the tip end of the string-like member 81 is connected to the small-diameter rod component 643. It is fixed to the handle 65 through a formed through hole 646 and a caulking material 83. The length of the string-like member 81 is substantially the same as the length of the operation rod 64 when the operation rod 64 is extended to the maximum. Therefore, as shown in FIG. 4, when the operation rod 64 is contracted, the string-like member 81 is bent in the operation rod 64, and when the operation rod 64 is fully extended, the string-like member 81 is The operating rod 64 is almost extended. When the handle 65 is raised with respect to the operation rod 64 with the operation rod 64 extended to the maximum, the tip of the string-like member 81 is pulled by the handle 65, and the key member 71 of the lock means 7 is moved to the key groove. It is pulled out between 610 and 620. In this way, the operation restriction of the operation means 6 by the lock means 7 can be released.

  When the direction in which the key member 71 is pulled by the string-like member 81 is different from the direction in which the key member 71 is pulled out from between the key grooves 610, 620, the key member 71 remains in the key groove even if it is pulled by the string-like member 81. 610 and 620 cannot be easily pulled out. Therefore, the pull-out release operation of the key member 71 by the string member 81 is performed with the operation rod 64 raised to the operation position as shown in FIG.

  Hereinafter, the procedure of the opening operation of the open surface lattice 10 of the present embodiment will be described with reference to FIGS.

  When opening the open surface lattice 10, first, as shown in FIG. 6, the operating rod 64 of the operating means 6 is raised from the stowed position to the operating position with the shoddle 15 of the window 14 opened. Normally, the operating rod 64 is housed in the lower horizontal lattice 12 in a contracted state. The length L1 of the operation rod 64 in the contracted state is smaller than the opening length W between the window frame of the window 14 and the shoji 15 in the open state. Therefore, if the window 14 is fully opened, the operation rod 64 can be raised to the indoor side.

  Next, as shown in FIG. 7, the handle 65 is grasped to extend the operating rod 64 to the maximum, and the handle 65 is raised from the storage position to the operating position with respect to the operating rod 64. Thus, as described above, the handle 65 pulls the distal end side of the string-like member 81 to pull out the key member 71 of the locking means 7 from between the key grooves 610 and 620 of the operating means 6, and the operating means 6 by the locking means 7. Release the operation restrictions. As shown in FIG. 7, the length L2 when the operating rod 64 is extended to the maximum is larger than the opening length W. Therefore, even if the intruder reaches his / her hand from the outside of the open surface lattice 10, the handle 65 at the tip of the operation rod 64 cannot be raised and lowered, and the intruder restricts the operation means 6 by the lock means 7. It cannot be canceled.

  After that, as shown in FIG. 8, the handle 65 of the operation means 6 is held and the operation rod 64 is rotated around the axis. As a result, as described above, the slider 5 is moved from the engagement position to the release position via the crank mechanism of the operation means 6, and the engagement of the movable vertical lattice 22 with respect to the slider 5 is released. The movable vertical grid 22 released from the engagement with the slider 5 falls by its own weight, and the hook member 23 is caught on the upper horizontal grid 11. Then, as shown in FIG. 9, if the movable vertical lattice 22 is horizontally moved along the longitudinal direction of the upper lateral lattice 11, a part of the surface lattice of the open surface lattice 10 can be opened.

  As described above, in the open surface lattice 10 of the present embodiment, the operation rod 64 of the operation means 6 is raised to the indoor side, and the handle 65 provided at the tip of the operation rod 64 is raised to release the release means 8. If the restriction by the key member 71 of the lock means 7 is not released by pulling the cord member 81, the operating rod 64 cannot be rotated, and the movable vertical lattice 22 is disengaged to open the surface lattice. I can't. Therefore, even if the window 14 is opened and an intruder or the like can put his hand from the outside of the open face lattice 10 to raise the operating rod 64 to the indoor side, the operating rod 64 protruding to the indoor side The lock means 7 cannot be released by operating the handle 65 at the tip. Therefore, even when the window 14 is opened, an intruder or the like cannot operate from the outside to open the surface lattice, and is excellent in crime prevention.

  Further, in the open surface lattice 10 of the present embodiment, by pulling the string member 81 of the release means 8 and pulling out the key member 71 of the lock means 7 from between the key grooves 610 and 620 of the operation means 6, Since the restriction of the rotational operation of the operating rod 64 is released, an open type surface lattice excellent in crime prevention can be configured very simply, and an inexpensive open type surface lattice can be provided to the market.

  Furthermore, in the open surface lattice 10 of the present embodiment, since the tip of the string-like member 81 of the release means 8 is fixed to the handle 65 that is gripped when the operating rod 64 is rotated, only the handle 65 is raised. Thus, the string member 81 can be pulled to release the restriction by the key member 81. In the event of an emergency such as a fire, the operation restriction of the operation means 6 by the lock means 7 can be quickly released, and there is no need for time and effort to open the face grid in an emergency.

  Furthermore, in the open surface lattice 10 of the present embodiment, the operation rod 64 of the operation means 6 is configured to be extendable and retractable by a plurality of rod parts. While the length of the operation rod 64 is reduced, the operation rod 64 can be extended to cause the handle 65 at the tip to protrude greatly toward the indoor side when it is raised to the indoor side. Therefore, even when the operation rod 64 must be shortened to enable the operation rod 64 to be turned up and down, the handle 65 is extended to a position where an intruder or the like cannot reach by extending the operation rod 64. It can be protruded indoors. The present invention can also be applied to a window having a relatively small opening length W between the window frame and the shoji screen in the open state.

  The open type surface grating 10 of the present embodiment has been described above, but the open type surface grating according to the present invention can be implemented in other forms.

  For example, in the above embodiment, the operation means 6 for moving the slider 5 is constituted by a crank mechanism, but the present invention is not limited to this, and for example, a pinion-rack mechanism or the like may be adopted. good. Any other transmission mechanism may be employed as long as the rotational movement around the axis of the operating rod 64 can be converted into the linear movement of the slider 5. Various design changes can also be made for the lock means for restricting the operation of the operation means. For example, the swinging motion of the crank arm 63 of the operation means 6 may be directly restricted by a stopper. The linear movement may be restricted by a stopper.

  Further, in the above embodiment, the releasing means 8 for releasing the restriction by the locking means 7 is constituted by the string-like member 81, and the tip of the string-like member 81 is fixed to the handle 65, but it is not necessarily limited to this. For example, a tab or the like may be provided at the tip of the string-like member 81, and the locking means 7 may be released by pulling the tab directly.

  The present invention can be carried out in a mode in which various improvements, modifications, and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. In addition, any invention-specific matters may be replaced with other technologies within a range where the same action or effect occurs, and the integrally-configured invention-specific matters are constituted by a plurality of members. Alternatively, the invention specific items configured by a plurality of members may be implemented in an integrated configuration.
