Description

  The present invention relates to a stopper member and an opening window, and more particularly, to a stopper member and an opening window that are arranged between a frame body and a shoji that constitute the opening window and restrict the opening degree of the shoji with respect to the frame body.

  Conventionally, an opening window having a shoji that can be opened and closed with respect to the frame body regulates the opening degree of the shoji with respect to the frame body between the frame body and the shoji, and if necessary, this opening degree. A stopper member (stay) that can release the restriction and fully open the shoji is used. An example of such a stopper member is shown in Patent Document 1.

  FIG. 14 is a side view showing a conventional stopper member attached to the right opening window. As shown in FIG. 14, the conventional stopper member 100 includes an arm 110 having a base end swingably attached to a small edge portion of a shoji 102 and an engagement pin 112 provided at a distal end portion, and a frame body. And a guide frame 120 attached to the inside of 101. The guide frame 120 is formed with a guide groove 122 that engages with the engagement pin 112 and slides the engaged engagement pin 112 so as to extend in the vertical direction. An opening 122A that allows the engagement pin 112 to enter and exit when the shoji 102 is closed is formed on the outdoor side (the right side in the drawing) of the lower end portion of the guide groove 122. The guide frame 120 is provided with a shutter portion 130 that slides along the guide groove 122 to open and close the opening portion 122A.

  According to the configuration of the stopper member 100 described above, when the shoji 102 is opened in a state where the shutter portion 130 is operated and the opening 122A is closed, the arm 110 swings with the base end portion as the fulcrum, The provided engaging pin 112 slides upward in the guide groove 122. The sliding engagement pin 112 finally comes into contact with the upper end portion of the guide groove 122 and cannot slide any more. Thus, the opening degree of the shoji 102 is regulated by the sliding range of the engaging pin 112, that is, the swinging range of the arm 110.

Further, when the shoji 102 is opened with the opening 130A opened by operating the shutter part 130, the engaging pin 112 comes out of the guide groove 122 from the opening 122A. In this case, since the engaging pin 112 and the guide groove 122 are not engaged with each other, the shoji 102 can be opened largely without being restricted by the opening degree by the arm 110.
According to such a stopper member 100, by operating the shutter unit 130, one of a state in which the opening degree of the shoji 102 is regulated and a state in which the opening degree of the shoji 102 is not regulated is selected. Thus, the shoji 102 can be opened and closed.

However, in the stopper member 100 described above, the tip of the arm 110 is not particularly urged toward the frame 2, and therefore the tip of the arm 110 may open toward the guide frame 120. For this reason, when the shoji 102 is closed, there is a problem that the tip of the arm 110 hits the frame body 101 or the like and the shoji 3 cannot be opened and closed smoothly.
The objective of this invention is providing the stopper member and opening window which can perform opening and closing of a shoji smoothly.

  The present invention is a stopper member for restricting the opening degree of the shoji with respect to the frame body in an open window having a frame body and a shoji that is attached to the frame body so as to be openable and closable. An arm swingably attached to the shoji and provided with an engagement pin at the tip, an opening attached to the frame for introducing the engagement pin is formed, and the engagement A guide frame having a guide groove for guiding a pin, and the arm includes a base plate attached to the shoji, an arm body whose base end is swingably attached to the base plate, and the base plate. And a restraining member that presses against the base plate while introducing the arm body into the gap when the shoji is closed.

  According to the present invention, when the shoji is closed, the restraining member presses the arm main body toward the base plate while introducing the arm main body into the gap between the base plate. Pressed down. For this reason, since the front end side of an arm main body does not open and collide with a frame etc., the opening / closing operation | movement of a shoji can be performed smoothly.

  Here, the restraining member employs a configuration having a restricting portion that restricts the swinging of the arm main body so that the engagement pin escapes from the opening while pressing the arm main body toward the base plate. it can. According to such a configuration, the arm main body can be held at the position facing the guide frame by the restricting portion, and the operability of the shoji is further enhanced.

  The casement window of the present invention includes the stopper member.

  According to the stopper member and the opening window of the present invention, there is an effect that the shoji can be opened and closed smoothly.

A stopper member according to an embodiment of the present invention will be described with reference to the drawings.

In the state shown in FIG. 6, when the head 53A of the pin-shaped member 53 is rotated while being urged to the left in the drawing by a tool such as an operator's fingertip, a screwdriver, or a special key, FIG. As shown, the pin-shaped member 53 is locked to the knob main body 51, whereby the tip end portion 53 </ b> B of the pin-shaped member 53 protrudes from the left side of the knob main body 51 in the drawing. When the protruding tip 53B is inserted into the slit S and engaged with the slit S, the downward sliding of the knob body 51 is restricted, and the slider 40 is thereby fixed at the closed position.

  In the state shown in FIG. 7, when the head 53A is rotated in the direction opposite to the above, the pin-like member 53 and the knob body 51 are unlocked, and as shown in FIG. The tip 53B of the member 53 is retracted into the knob body 51, the engagement between the tip 53B and the slit S is released, and the knob body 51 can be slid downward. Therefore, the position of the slider 40 can be switched between the closed position and the open position by operating the operation knob 50 up and down.

In this manner, a lock mechanism that restricts the sliding of the operation knob 50 is configured by using the slit S for connecting the operation knob 50 and the slider 40. Therefore, it is not necessary to separately form a dedicated slit or hole used for the lock mechanism, so that the air tightness and water tightness of the frame body 2 can be secured.
Further, in this embodiment, the pin-like member 53 that restricts the sliding of the knob body 51 is provided as a lock mechanism. For example, the operation knob 50 is operated by a child with mischief and the shoji 3 is fully opened. Can be prevented and safety is increased.
Further, in the present embodiment, a configuration is adopted in which the forward / backward operation of the pin-shaped member 53 is performed by applying a tool, a dedicated key, or the like at a position that becomes a blind spot from the outside of the building. It is possible to prevent the lock mechanism from being released from the outside by reaching out from the gap with 3, which is advantageous in terms of crime prevention.

Next, the operation of the stopper member 4 of this embodiment will be described.
FIG. 8 is a front view showing the stopper member 4 when the shoji 3 is opened in a state where the opening degree of the shoji 3 is not regulated, and FIG. 9 is a side view of FIG. 10 is a front view showing the stopper member 4 when the shoji 3 is closed, and FIG. 11 is a side view of FIG.
First, the case where the shoji 3 is closed as shown by the arrow B in FIG. 8 in a state where the opening degree of the shoji 3 is not regulated will be described. The slider 40 is assumed to be in the open position. As described above, the upper end of the arm body 12 is biased toward the base plate 11 by the spring 15 (FIG. 3). However, since the arm body 12 is long in the vertical direction, the engagement pin 17 is engaged with the guide groove 33A. In a state where they do not match (a state where the opening degree of the shoji 3 is not regulated), as shown in FIG. 9, the lower end portion of the arm body 12 may open to the guide frame 30 side (right side in the drawing). In this case, when the shoji 3 is closed, as shown in FIG. 8, the lower end portion of the arm body 12 opened to the guide frame 30 side comes into contact with the outdoor side surface Y of the frame 2, thereby With the movement, the arm body 12 swings in the direction of arrow C toward the restraining member 13. The swinging arm main body 12 is guided to the gap between the presser plate 19 and the base plate 11 by the presser plate 19, and the engaging pin 17 provided at the lower end of the arm main body 12 is opened. It enters the open part P side from the part Q2.

  When the shoji 3 is completely closed, as shown in FIG. 10, the right end 12R of the arm main body 12 in the drawing abuts against the projection 34, so that the arm main body 12 faces the opening Q1 (the right side in the drawing). Oscillation is restricted. Further, the left end portion 12L of the arm main body 12 abuts on the restriction portion 18 of the restraining member 13, whereby the swinging of the arm main body 12 toward the opening Q2 (left side in the drawing) is restricted. As shown in FIG. 11, the lower end portion of the arm main body 12 is pressed by the presser plate 19 toward the base plate 11 while being introduced into the gap between the presser plate 19 and the base plate 11. Thus, as shown in FIG. 10, the arm body 12 and the guide frame 30 face each other, the engagement pin 17 is positioned below the opening P, and the engagement pin 17 can be introduced into the guide groove 33A. Become.

  When the operation knob 50 is slid upward in this state, as shown in FIG. 4, the slider 40 is in the closed position and the open portion P is blocked by the slider 40, and the engagement pin 17 is placed in the guide groove 33A. Be bound. When the shoji 3 is opened in this state, the engaging pin 17 is introduced into the guide groove 33A, and the opening degree of the shoji 3 is regulated by the arm body 12 as described above. When the shoji 3 is fully opened in a state where the opening degree of the shoji 3 is regulated in this way, as shown in FIG. 4, the engaging pin 17 is pivoted at the upper end of the guide groove 33A by the elastically deformable spring member 36. Be supported. Thereby, the shoji 3 is held in an open state, and the shoji 3 is not closed by wind or the like.

  Further, when it is desired to cancel the restriction of the opening degree of the shoji 3, after the shoji 3 is closed and the lock mechanism of the operation knob 50 is released as shown in FIG. 6, the operation knob 50 is slid downward. Thus, the slider 40 is set to the open position. When the shoji 3 is opened in this state, the engagement pin 17 at the lower end of the arm main body 12 is housed in the restraining member 13 while the arm body 12 is housed in the restraining member 13, and the engagement pin 17 is moved out of the guide groove 33A from the opening Q1. Therefore, the shoji 3 can be greatly opened without being restricted by the arm body 12.

  According to the stopper member 4 of the present embodiment, the upper end of the arm main body 12 is urged toward the base plate 11 by the spring 15, and the lower end of the arm main body 12 is pressed by the presser plate 19 when the shoji 3 is closed. This is a case where the lower end portion of the arm body 12 is opened to the guide frame 30 side because the portion is pressed against the base plate 11 side and introduced into the gap between the base plate 11 and the presser plate 19. However, when the shoji 3 is closed, the arm body 12 can be surely placed along the base plate 11 by the presser plate 19, and the shoji 3 can be opened and closed smoothly.

  In addition, when the shoji 3 is closed, the left end 12L of the arm main body 12 abuts on the restricting portion 18 of the restraining member 13, and the right end 12R of the arm main body 12 abuts on the protrusion 34. 12 can be restricted to a position directly facing the guide frame 30, the engagement pin 17 and the guide groove 33 </ b> A can be reliably engaged, and as a result, the opening / closing operation of the shoji 3 is further smoothed.

  In addition, openings Q1 and Q2 are formed at substantially symmetrical positions on both sides of the guide frame 30, and the engagement pin 17 is released from the opening Q1 opposite to the opening Q2 into which the engagement pin 17 is introduced. For example, when the stopper member 4 of this embodiment is attached to the right opening window, the protrusion 34 is replaced with the left mounting base 31B, and the above-described implementation is performed. By reversing the front and back surfaces of the base plate 11 and replacing the arm main body 12, the restraining member 13, and the base material 14, the stopper member 4 can be easily opened and the opening windows with different ease of use can be dealt with. For this reason, one stopper member 4 can cope with left and right or top and bottom opening, and an increase in cost applied to the stopper member 4 can be suppressed.

  In addition, this invention is not limited to the said embodiment. In the said embodiment, although the stopper member 4 was attached to the left opening window 1, you may attach to an upper opening window, a lower opening window, and a right opening window, and the kind of opening window is not limited. Note that this case can be easily dealt with by appropriately changing the position of each member.

Next, a modified example of the present invention will be described.

A knob main body 351 slidably attached in the vertical direction and an attachment plate 52 provided on the left side of the knob main body 351 in the figure are provided.

The knob body 351 is formed with a through hole 351A penetrating in the left-right direction in the drawing. A protrusion 351B that protrudes toward the spacer 353 is formed on the left side of the knob main body 351 in the figure above the through hole 351A.
The spacer 353 includes a spacer body 354 whose left surface is attached to the frame 2 and whose right surface is in contact with the knob body 351, and a protrusion 355 that protrudes upward from the upper end of the spacer body 354. . A claw portion 355A that protrudes beyond the tip position of the protrusion 351B is formed on the protruding portion 355 toward the knob body 351, and a tapered surface 355B is formed below the claw portion 355A.

Therefore, even if the knob main body 351 is slid downward in the state shown in FIG. 13, the protrusion 351B comes into contact with the upper surface of the protruding portion 355, and the downward sliding of the operation knob 350 is restricted. Accordingly, the slide of the operation knob 350 is locked.
On the other hand, by inserting a rod-shaped tool or the like into the through-hole 351A and elastically deforming the protruding portion 355 toward the frame body 2 side, the claw portion 355A is moved further to the left side than the tip portion of the protrusion 351B. The knob main body 351 can be slid downward without contacting the 351B and the claw portion 355A. Accordingly, the slide of the operation knob 350 is unlocked. Further, when the knob body 351 slid downward in this way is slid upward, the protrusion 351B slides while being in contact with the tapered surface 355B of the protrusion 355, so that the protrusion 355 moves toward the frame 2 side. By elastically deforming, the knob main body 351 can be operated until the projection 351B is positioned above the protruding portion 355. In this manner, the slide of the operation knob 350 returns to the locked state.
Therefore, according to the second modification, it is possible to easily switch between the state in which the slide of the operation knob 350 is locked and the state in which the slide of the slider 240 is unlocked.
