Description

  The present invention relates to a fitting prevention device for preventing a fitting such as a screen door from being detached from a fitting frame, and a fitting including the fitting.

Conventionally, as this kind of anti-slip device, a screen door is provided on a screen door, and the screen door is installed on the upper frame rail and the lower frame rail of the joinery frame by a quick operation, and this anti-skid operation is activated. The thing is known (refer patent document 1).
This detachment prevention device includes a case fixed to the upper lid of the screen door, a stopper (a detachment prevention member) supported by the case so as to protrude from the upper end of the case, and an urging force in the direction in which the stopper protrudes. Between the torsion coil spring and the lock position that engages with the stopper and prevents the stopper from rotating downward and the unlock position that allows the stopper to rotate downward. (A non-return stopper) and a coil spring that urges the slider toward the lock position.
In the initial state, the stopper is engaged with the slider in the unlock position, and when the screen door is erected on the joinery frame from this state, the stopper rotates downward. By this rotation, the engagement between the stopper and the slider is released, and the slider advances toward the lock position by the coil spring. Further, the installation of the screen door is finished, the stopper is rotated (returned) upward, and the slider reaches the lock position so as to sink under the stopper. Accordingly, the detachment stopper can be operated only by the quick operation.
Utility Model Registration No. 2539192

  In such a conventional anti-slip device, the anti-skid can be actuated (locking the stopper) only by the built-in operation, but since the slider is slidably provided on the case, the slide groove of the case If the slider and the slider are not accurately formed to have a predetermined dimensional tolerance, there is a problem that the slider does not slide smoothly in the slide groove. Similarly, even if foreign matter or dust adheres to the slide groove, the slider does not operate smoothly. In addition, it is necessary to arrange the slider and the coil spring that urges the slider side by side, and the entire apparatus becomes longer in the sliding direction of the slider, resulting in a problem that the apparatus becomes larger.

  It is an object of the present invention to provide a fitting prevention device and a fitting including the fitting prevention device, which can smoothly and stably operate the removal prevention and can be configured compactly.

  The fitting prevention device of the present invention is provided at the upper end portion of the joinery that is attached to the upper and lower frame rails of the joinery frame by lifting and lowering, and prevents the attached joinery from being disengaged from the upper and lower frame rails. In the fitting prevention device, the lowering means moves relatively downward by the raising operation of the hand, and the locking means that moves up relatively by the lowering action of the hand, and the rotation according to the downward movement of the locking means. A non-return stopper that rotates in one direction from the start end position, engages with the locking means that moves upward at the end position of rotation, and controls the position of the non-return stopper, and rotates the non-return stopper in the middle of the rotation in one direction. And stopper urging means for urging toward the moving end position.

  According to this configuration, in the initial state, the locking means is in the upward movement position, and when the joinery is lifted and lowered in the joinery frame from this state, it first comes into contact with the upper frame rail by the tendon raising action. The locking means moves downward relatively. Further, the non-return stopper rotates in one direction from the rotation start end position in accordance with the downward movement of the detachment prevention means. Subsequently, when the operation is shifted to the lowering operation, the detachment prevention member moves up following this, but the non-return stopper is urged by the stopper urging means to reach the rotation end position. When the come-off prevention member returns to the upward movement position, the non-return stopper engages with the come-off prevention member and restricts the position thereof. In other words, the detachment stop can be actuated by the erection operation of the tendon. In this case, since the non-return stopper is configured to be rotatable, it is not structurally difficult to operate, and stable operation can be maintained, and the stopper can be disposed in a relatively small space.

  In this case, the locking means includes a locking member configured to be pivotable in the vertical direction about the support shaft, and a return spring that biases the locking member in the upward movement direction. preferable.

  According to this configuration, since the come-off prevention member is also configured to be rotatable, a stable operation can be maintained and the space efficiency can be improved also in this respect. Further, it is possible to configure the locking means by a locking member having a spring property (integrated type), but the locking member is urged in the upward movement direction by a return spring provided separately. Therefore, the detachment prevention member can be reliably moved up following the lowering operation.

  In these cases, it is preferable that the stopper urging means is constituted by a bidirectional spring disposed so that the urging direction thereof exceeds the dead center with respect to the rotation support shaft of the non-return stopper.

  According to this configuration, when the urging direction of the stopper urging means is on the rotation start end position side with respect to the dead point, the stopper urging means urges the check stopper toward the rotation start end position and When the point is on the rotation end position side, the stopper urging means urges the check stopper toward the rotation end position. That is, the stopper urging means urges the non-return stopper in the reverse direction at a substantially middle point (dead point) of the rotation range. As a result, in the initial state in which the locking means is in the upward movement position, the check stopper can be moved to the rotation start position, so that the check stopper moves to the rotation end position during transportation and storage. Can be prevented. On the other hand, when the come-off prevention means is moved up by the lowering operation, the check stopper can be independently moved to the rotation end position independently. Moreover, the above-described operation of the check stopper can be achieved by a single stopper biasing means.

  In these cases, the detachment preventing means engages with the guide portion that guides the sliding of the non-return stopper that rotates from the rotation start end position to the rotation end position, and the non-return stopper that rotates to the rotation end position. The non-return stopper has an engaged portion that comes into contact with the guide portion or the engaging portion as the detent means moves downward, and the engaged portion is at the rotation start end position. It is preferable that it is located at a distance from the guide part and is close to the engaging part at the rotation end position.

  According to this configuration, it is possible to surely switch between the detachment prevention state and the detachment prevention release state depending on the difference in height between the stepped guide part and the engagement part, and between the detachment prevention means and the check stopper. Mutual sliding contact and engagement can be performed smoothly.

  In these cases, the check stopper has an operation portion for rotating the check stopper in the reverse direction from the rotation end position to the rotation start position against the stopper biasing means. preferable.

  According to this configuration, the anti-disengagement state can be easily released by rotating the check stopper from the rotation end position to the rotation start end position (reset to the rotation start end position) by the operation unit. When the component parts of the device are housed in a case (frame) or the like, the operation unit is moved to the outside in a state where the check stopper is moved to the rotation end position in order to facilitate the above-described release operation by the user. It is preferable that it is exposed.

  In these cases, it is preferable that the operation unit is configured so that the non-return stopper rotated to the rotation start end position can be rotated to the rotation end position.

  According to this configuration, if the non-return stopper is accidentally released from the rotation end position to the rotation start position after the fitting is properly mounted on the joinery frame, it can be easily returned (prevention from being released) Can be set). Also in this case, it is preferable that at least a part of the operation portion is exposed to the outside in a state where the check stopper is moved to the rotation start end position.

  The joinery of the present invention is characterized by including the above-described detachment prevention device.

  According to this configuration, the detachment prevention device can be automatically activated only by the erection operation. Moreover, since the anti-slip device itself has both operational stability and compactness, it can be easily attached without requiring any improvement to the joinery. In addition, the “jointing tool” referred to in the claims is a concept including a screen door and various sliding doors (paper shovels).

  As described above, according to the fitting prevention device and joinery of the present invention, it is possible to actuate the slip prevention by the building operation, and to smoothly and stably operate the slip prevention. Moreover, the whole apparatus can be comprised compactly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a sliding window with a screen door (joint) 3 provided with a locking device according to the first embodiment of the present invention, and FIG. 2 is an enlarged longitudinal sectional view thereof. As shown in both figures, the sliding window is composed of a window frame (joint frame) 1, an external door 2 a and an internal door 2 b that are attached to the window frame 1 so as to be openable and closable, and a screen door 3 incorporated on the outdoor side of the external door 2 a. And. The window frame 1 is framed by an upper frame 11, a lower frame 12, and left and right vertical frames 13, 13, and an upper screen door rail (upper frame rail) 14 that is suspended from the upper frame 11 at the outermost end. However, the lower frame 12 is provided with a lower screen door rail (lower frame rail) 15 erected and positioned at the outermost end. The screen door 3 is divided by the upper frame 31, the lower frame 32, and the left and right vertical rods 33, 33, the middle frame 34 that is horizontally passed between the vertical rods 33, 33, and the middle beam 34. And a pair of nets 35, 35 stretched in the upper and lower inner space. The screen door 3 includes a pair of slide blocks 36 disposed so as to be separated from the upper end portion on the indoor side in the finding direction, and a pair of door block blocks disposed so as to be separated from the lower end portion on the indoor side in the finding direction ( (See FIG. 2). Each slide block 36 is provided with a bifurcated engagement piece 37 that is slidably engaged with the upper screen door rail 14 and allows the screen door 3 to be attached by a jerking. A door wheel 39 that rolls on the lower screen door rail 15 is provided. Each slide block 36 is positioned on the inner side of the upper horizontal piece 311 extending from the upper end of the upper collar hollow portion 310 of the upper collar 31 to the indoor side, and is fixed to the finding surface of the upper collar hollow section 310. Is located on the inner side of the lower horizontal piece 313 extending from the lower heel hollow portion 312 of the lower heel to the indoor side, and is fixed to the finding surface of the lower heel hollow portion 312. Thereby, the screen door 3 is mounted so that the screen body 35 protrudes somewhat from the upper and lower screen door rails 14 and 15 to the outdoor side. Furthermore, the screen door 3 has a pair of anti-slip devices 4 and 4 so as to be incorporated in each slide block 36. Each anti-separation device 4 is slidably engaged with the upper screen door rail 14 with the bottom slightly raised from the above-mentioned bifurcated engagement piece 37, and the screen door 3 is disengaged from the upper and lower screen door rails 14 and 15 by jerking operation. Is blocking. Note that the number of the stopper devices 4 is not limited to two, and may be any number. Moreover, you may make it provide the locking device 4 and the door pulley 39 in a housing directly.

  Next, each of the anti-separation devices 4 will be described in detail with reference to FIGS. The locking device 4 includes a frame 5 fixed to the upper arm 31 of the screen door 3, a locking device 6 that moves up and down with the upper screen door rail 14 sandwiched with the frame 5, and a reverse locking mechanism that locks the locking device 6 in the locking status. A stop stopper 7 and stopper biasing means 8 for biasing the check stopper 7 are provided. Further, the locking means 6 includes a locking member 61 that moves up and down, and a return spring 611 that biases the locking member 61 upward.

  The frame 5 includes a front plate 51, a back plate 52, and a bottom plate 53, and is formed by being bent into a substantially U-shaped cross section so as to open the top. A rectangular lower opening 54 is formed at the center of the bottom plate 53. Two long holes 55 are formed in the left and right ends of the back plate 52, and the anti-separation device 4 is screwed to the upper collar 31 via the slide block 36 by the long holes 55. The front plate 51 protrudes upward from the back plate 52 and engages with the anti-slip member 61 protruding from the back plate 52 so as to sandwich the upper screen door rail 14. Further, a stopper projection 56 is provided on the front plate 51 so as to be raised in the vicinity of the locking member, and the position of the upward movement position of the locking member 61 biased by the return spring 611 is regulated. ing.

  The anti-slip member 61 is formed integrally with a head portion 62 on the distal end side and an arm portion 63 on the proximal end side so as to have a substantially saddle-shaped cross section, and is attached to the frame 5 via a support shaft 64 at the base portion of the arm portion 63. The shaft is pivotally supported. A rail contact surface 68 that is curved in a deformed mountain shape and a guide wall portion 69 that faces the front plate 51 of the frame 5 across the rail contact surface 68 are provided on the upper surface of the head portion 62. While the surface 68 abuts the lower end surface of the upper screen door rail 14 to prevent the screen door 3 from being detached, the guide wall portion 69 sandwiches the upper screen door rail 14 between the front plate 51 of the frame 5 and guides the opening and closing of the screen door. To do. In addition, on the lower surface of the linkage portion between the head portion 62 and the arm portion 63, a pressing portion 65 that moves the check stopper 7 downward by moving it downward from the release prevention release state, and guides the slide of the check stopper 7. And an engaging portion 67 that is held by the non-return stopper 7 and is prevented from moving downward. In the initial state of the tendon that operates the stopper, the check stopper 7 is in contact with the pressing portion 65. When the stopper member 61 starts rotating from this state, the contact point with the check stopper 7 is the guide point. When the stopper member 61 stops rotating when it moves to the portion 66 and contacts the guide portion 66, and the stopper member 61 returns, the contact point goes over the guide portion 65 and engages with the engaging portion 67. .

  The support shaft 64 is provided with a return spring 611 so as to be wound around the support shaft 64, and the return spring 611 is urged to rotate the slip-off preventing member 61 so that the rail contact surface 68 moves upward. is doing. The return spring 611 is a torsion coil spring and is omitted in the drawing, but one end is locked to the frame 5 and the other end is locked to the arm portion 63 while being wound around the support shaft 64. Therefore, the release prevention member 61 in the release release release state (initial state) is moved to the upward movement position by the return spring 611 and is in contact with the stopper projection 56 of the frame 5, and is biased by the stopper biasing means 8. The non-return stopper 7 is in contact with the lower side. The locking member 61 relatively moves down by the raising operation of the kneading and relatively moves up by the lowering operation of the kneading. The return spring 611 in the present embodiment is a torsion coil spring wound around the support shaft 64, but may be anything as long as it urges the locking member 61 upward. For example, it may be a coil spring or a leaf spring. Further, the locking means 6 may be configured integrally with the locking member 61 by making the arm portion 63 thin and springy.

  The non-return stopper 7 is rotatably supported by a cantilevered rotation support shaft 71 provided on the back plate 52 of the frame 5, and a support plate portion 72 formed in a fan shape and a frame from the support plate portion 72. 5 and a substantially “T” -shaped operation portion 73 provided so as to protrude toward the front plate 51 side. The support plate portion 72 has a biasing means locking portion 74 that locks the stopper biasing means 8 at the fan-shaped tip position. The operation portion 73 is formed in a substantially “T” shape by an operation portion main body 75 from which the support plate portion 72 protrudes in the finding direction and an engaged portion 77 that protrudes from the support plate portion 72 in the finding direction. ing. The engaged portion 77 faces the release preventing member 61 from the lower side, and sequentially engages with the pressing portion 65, the guide portion 66, and the engaging portion 67 with respect to the release preventing member 61 that moves downward. At this time, the position of the non-return stopper 7 that is in contact with the locking member 61 in the unlocking released state from the lower side is the rotation start position, and the engaged portion 77 is the engaging portion in the locking state. The position of the check stopper 7 in the vicinity of 67 is a rotation end position, and the check stopper 7 is configured to be rotatable between a rotation start end position and a rotation end position. The front-view overlap portion of the locking member 61 of this embodiment with the support plate portion 72 is notched (not shown), and the support plate portion 72 does not interfere with the locking member 61 indoors and outdoors, and the operation unit. 73 engaged portions 77 are appropriately engaged with the locking member 61. Thereby, the locking member 61 and the non-return stopper 7 can be arranged as close as possible, and the locking device 4 is downsized. In addition, although the base end side of the operation part 73 also serves as the engaged part 77, the operation part main body 75 and the engaged part 77 may be provided separately. Further, the operation portion main body 75 is concealed in the frame 5 in a state where the check stopper 7 has moved to the rotation start end position, and protrudes downward from the lower opening 54 of the frame 5 in a state in which it has moved to the rotation end position. . This facilitates the operation of the non-return stopper (release prevention release operation), and since it does not protrude from the frame 5 at the rotation start end position, it is easy to visually check whether or not it is in the release prevention state. Further, the outer surface of the operation unit main body 75 has knurled irregularities so that it can be easily operated without slipping by hand, but is not limited thereto, and may be, for example, a lever.

  Stopper biasing means 8 is provided at a position slightly apart from the check stopper 7. The stopper urging means 8 is an improvement of a torsion coil spring having a desired spring constant, and is a non-return stopper 7 that has moved from a substantially intermediate point between the rotation start end position and the rotation end position to the rotation start end position side. Is biased toward the rotation start end position, while the non-return stopper 7 moved to the rotation end position side is biased toward the rotation end position. The bent end portion 81 which is one end of the stopper urging means 8 is engaged with the urging means engaging portion 74 of the check stopper 7, and the support end portion 82 which is the other end is the front plate 51 and the back plate 52. Is supported by winding on a support pin 83 passed between the two.

  The substantially intermediate point is at the position of the check stopper 7 in a state where the extension line in the urging direction of the bent end portion 81 of the stopper urging means 8 intersects the axis of the rotation support shaft 71 of the check stopper 7. Correspondingly, the urging direction of the stopper urging means 8 exceeds the so-called dead point. Therefore, with respect to the locking member 61 that moves downward against the return spring 611 by the lifting operation, the non-return stopper 7 is brought into contact with the stopper urging means 8 in the state where it comes into contact with the stopper member 7. The rotation starts from the position. When the downward movement of the stopper member 61 advances and the stopper biasing means 8 eventually exceeds the dead center, the stopper biasing means 8 biases the check stopper 7 toward the rotation end position, and the stopper stopper 7 The rotation end position is reached away from the slip prevention member 61 (actually, it once contacts the guide portion 66 and reaches the rotation end position by the upward movement of the slip prevention member 61). On the other hand, the locking member 61 further moves down, but eventually, when the raising operation of the knives shifts to the lowering operation, it turns upward and returns to the upward movement position. In this state, the engaging portion 67 of the locking member 61 faces the engaged portion 77 of the check stopper 7, and the downward movement of the locking member 61 is restricted (a locking state). Further, when the non-return stopper 7 is rotated toward the rotation start end position against the stopper urging means 8 from this non-removed state, the non-return is detected at the moment when the stopper urging means 8 exceeds the dead point. The stopper 7 is pulled back and returned to the rotation start position (release prevention release state). In this embodiment, the stopper urging means 8 is constituted by an improved torsion coil spring. However, the spring does not have to be substantially square-shaped, and is not limited to the spring, but is attached in a direction that can be expanded and contracted. Anything can be used.

  The detachment prevention device 4 is configured as described above, and the operation of the detachment prevention device 4 will be briefly described below together with the procedure for installing the screen door 3. When the screen door 3 is attached, the locking device 4 is in the state of FIG. That is, in the initial state, the stopper member 61 is in the upward movement position, and the check stopper 7 is in the rotation start end position. In this state, the detachment prevention means 6 is not restricted by the non-return stopper 7 and can be moved downward freely. From there, the screen door 3 is built up by raising and lowering the screen door 3 on the window frame 1, but the anti-disengagement means 6 that comes into contact with the upper frame rail 14 moves down relatively. In addition, the non-return stopper 7 rotates in one direction from the rotation start end position toward the rotation end position as the detachment prevention means 6 moves downward. Along with this, the stopper urging means 8 also starts to rotate reversely from the check stopper 7 around the support end 82 supported by the frame 5.

  At the stage of starting rotation, the stopper urging means 8 is urged toward the rotation start end position. The stopper urging means 8 that has exceeded the dead center with respect to the rotation support shaft 71 of the check stopper 7 urges the check stopper 7 in the direction of the rotation end position, so that the check stopper 7 rotates and comes off. It abuts on the guide portion 66 of 61. In this way, the locking member 61 can move down to a position where the guide portion 66 contacts the check stopper 7 as shown in FIG.

  Subsequently, when shifting to the lowering operation, the locking member 61 is moved upward by the return spring 611, but the check stopper 7 released from the guide portion 66 is biased by the stopper biasing means 8 and is turned to the end of rotation. Reach position. When the locking means 6 returns to the upward movement position, the engaged portion 77 of the check stopper 7 is positioned below the engaging portion 67 of the locking member 61 as shown in FIG. The stopper member 61 is restricted from moving downward by the check stopper 7. In other words, the detachment stop can be actuated by the erection operation of the tendon.

  When releasing the stopper 4, the operating portion 73 provided on the stopper 7 is operated to rotate the stopper 7 in the direction of the rotation start position. 7 is urged in the direction of the rotation start end position and starts to rotate to move to the rotation start end position. As a result, since the release prevention release state is established, the release prevention member 61 can be moved downward, and the screen door 3 can be easily removed from the window frame 1 by a quick operation. Further, with the above structure, the non-return stopper 7 automatically returns to the rotation start end position without completely operating the operation unit 73 to the rotation start end position, so that the release stopper can be easily and reliably released without malfunction. .

  When the check stopper 7 is in the rotation end position, the operation portion 73 protrudes from the lower opening 54 of the frame 5, and when the check stopper 7 is in the rotation start position, the operation portion 73 is in the frame 5. Is in the box. This makes it easy to see whether the check stopper 7 is at the rotation end position or the rotation start position, and the check stopper moves to the rotation end position during storage or transportation. Can be surely prevented.

  Further, since the slip-off prevention device 4 is provided so as to protrude from the upper side of the upper door 31 of the screen door 3, the operation portion 73 is easy to operate with a structure in which it protrudes and appears in the lower opening 54 of the slip-off prevention device 4. Therefore, the detachment prevention device 4 can be easily released from the indoor side. However, the present invention is not limited to this, and the upper horizontal piece 311 and the lower horizontal piece 313 of the lower heel 32 are eliminated, and the stopper device 4 is accommodated in the upper ledge 31, and the door wheel 38 is placed in the lower heel 32. May be stored. At that time, it is desirable to make the operation portion 73 easy to operate from the indoor side by, for example, projecting the operation portion 73 to the interior surface of the upper lid.

  Next, with reference to FIG. 6, a second embodiment of the anti-slip device of the present invention will be described. Note that description of the same parts as those in the first embodiment is omitted. The locking device 40 of the second embodiment includes the same frame 5, return spring 611, and stopper urging means 80 as those of the first embodiment, and a locking member whose shape and positional relationship are different from those of the first embodiment. 610 and a non-return stopper 70.

  The anti-slip member 610 is rotatable about the support shaft 640, and is moved up and down by a rail contact surface 680 coming into contact with the upper screen door rail 14 on the upper surface of one end extending obliquely upward from the support shaft 640. Is arranged. A pressing portion 650, a guide portion 660, and an engaging portion 670 are formed on the upper surface of the other end extending obliquely downward from the support shaft 640.

  The non-return stopper 70 includes a support plate portion 720 having a substantially trapezoidal cross section that is rotatably supported around a rotation support shaft 710 and an operation portion 730 provided at one end of the support plate portion 720. The support plate portion 720 is appropriately engaged with the anti-separation member 610 because it is on the same surface in the indoor / outdoor direction, but the operation unit 730 is displaced in the indoor / outdoor direction and does not interfere with each other. The support plate 720 includes an engaged portion 770 that abuts against the guide portion 660 and the engaging portion 670 at one end, and a pressed portion 750 that abuts against the pressing portion 650 at the other end, and an urging means locking portion. 740.

  The anti-separation device 40 of the second embodiment is configured as described above, and the operation will be described below along the construction of the screen door 3. When the screen door 3 is attached, the locking device 40 is first in the upward movement position where the rail contact surface 680 has moved upward as much as possible in the initial state, as shown in FIG. 70 is moved to the rotation start position. When the screen door 3 is then lifted and lowered on the window frame 1 by a steadily moving operation, the detachment prevention member 610 is rotated by the gradual lifting operation, and the pressed portion 750 is pushed by the pressing portion 650 so that the check stopper 70 Also rotate in one direction.

  The stopper urging means 80 that rotates along with this urges the check stopper 70 in the direction of the rotation start end position while contracting, but the dead center with respect to the rotation support shaft 710 of the check stopper 70 in the middle. By exceeding, the non-return stopper 70 is urged toward the rotation end position, and the engaged portion 770 comes into contact with the guide portion 660 (see FIG. 6B).

  Subsequently, when shifting to the lowering operation, the come-off prevention means 60 rotates following this, but the non-return stopper 70 detached from the guide portion 660 is urged by the stopper urging means 80 and is turned to the end of rotation. The position is reached (see FIG. 6C). That is, even with the anti-slip device 40 of the second embodiment, the anti-skid can be activated by the erection operation.

  Next, with reference to FIG. 7, a third embodiment of the locking device of the present invention will be described. The difference from the first embodiment of the detachment prevention device 45 is that the operation portion 735 protrudes from the frame 5 in a state where the non-return stopper 7 is at the rotation start end position. That is, the operation unit 735 according to the third embodiment is formed sufficiently longer than the operation unit 73 according to the first embodiment, and protrudes from the frame 5 so as to be operable in an initial state. In this way, in addition to the function of moving the locking means 6 downward and automatically locking the locking, the operating portion 73 is operated to move the check stopper 7 from the rotation start position to the rotation end position. Since the release stopper can be manually applied, when the release stopper is released due to a malfunction, it is not necessary to stop the release by the operation, and the release can be stopped by the operation unit 73.

  Note that the anti-slip device of the present invention can also be applied to a screen door attached in a horizontal manner. In such a case, the detachment prevention device is mounted on the side of the screen door.
