Description

The present invention relates to a sliding window stay constituted by a planar four-bar linkage mechanism and a sliding window provided with the stay.

The vertical sliding window and horizontal sliding window can open and close the shoji placed inside the window frame by an operator operating from the indoor side, and open the shoji approximately 90 degrees. Can do.
Such sliding windows are widely used because they have good features such as good sealing properties and the ability to wipe and clean both sides of the glass screen from the indoor side. The side sliding windows support the shoji so that it can be opened and closed with respect to the window frame by a pair of left and right stays.

As an example of such a sliding window stay, a vertical sliding window will be described as an example. A window frame mounting material (frame mounting plate, fixing member) mounted on the upper and lower horizontal frames of the window frame, and one end of the window frame mounting material. A short arm (first arm) pivotally attached to one end of the door, and a shoji attachment plate (sash attachment plate, window shoji attachment plate) that is pivotally attached to the other end of the short arm and attached to the side of the shoji ) And a long arm (second arm) whose one end is pivotally attached to the intermediate portion in the longitudinal direction of the shoji attaching plate and the other end is pivotally attached to the other end of the window frame attaching member. Some of them are configured by a link mechanism (see, for example, Patent Documents 1 and 2), and the sliding window stay having such a configuration is a simple configuration that does not use a slider, so that it is difficult for backlash to occur and the sliding door can be opened and closed. It is possible to perform the operation stably and reliably. There is a feature that that.

Further, in the sliding window stay constituted by such a planar four-bar linkage mechanism, in order to prevent the sliding window from being damaged when a gust of wind blows, the pivotal axis connecting the short arm and the window frame mounting material ( Some have a stopper (around the base end of the short arm) and between the shoji mounting plate and the long arm (see protrusions 33 and 31 of Patent Document 1).

Japanese Patent No. 3172348 (paragraph [0030], FIG. 1) Japanese Patent No. 3803849 (FIGS. 1, 3, and 6)

The stopper in the conventional sliding window stay as described above exhibits a certain effect such as prevention of breakage of the sliding window when a gust blows as described above.
However, when a fully open shoji is thrown in the direction to open the shoji due to a gust of wind, etc., the slidable window stay attached to the shoji must be used to hold the squeeze impact, and the moment based on the wind pressure such as a gust of wind is a short arm. And it acts around the pivot (fulcrum) connecting the shoji mounting plate.
In addition, since the distance between the fulcrum and the stopper between the shoji attaching plate and the long arm is short, a large force based on the moment acts on the shoji attaching plate and the long arm.

  Therefore, it is necessary to reduce the thickness as much as possible due to space constraints, and the length is relatively long. Furthermore, excessive torsional stress is generated in the long arm where the bending portion for preventing interference is formed, causing plastic deformation. There is room for improvement from the viewpoint of improving the wind pressure strength.

The present invention is in view of the circumstances described above, it is an attempt to solve the Suberidashi window having a Suberidashi window stay and the stay capable of improving the resistance to wind pressure strength while suppressing an increase in cost with a simple arrangement The point is to provide.

A sliding window stay according to the present invention includes a window frame mounting material attached to a window frame, a short arm whose one end is pivotally attached to one end of the window frame mounting, and one end. Is pivotally attached to the other end of the short arm, and is attached to a shoji attachment plate, and one end is pivotally attached between one end and the other end of the shoji attachment plate, and the other end is A sliding window stay provided with a long arm pivotally attached to the other end of the window frame mounting material, wherein the short arm, the shoji mounting plate, and the long arm overlap each other along the window frame mounting material. From the state in which the shoji is closed, the short arm and the long arm are rotated in the same direction, the shoji mounting plate is rotated in a direction opposite to the rotating direction, and the short arm and the shoji mounting plate are outdoors. In the fully open state of the shoji that extends in the direction, the short arm and the shoji mounting plate in the direction The rotation restricting means for restricting the rotation, the short arm and the Rutotomoni provided between the sash mounting plate, the second rotation restricting means for restricting the rotation of the said direction of the shoji mounting plate and the long arm Is provided between the shoji mounting plate and the long arm, and the rotation restricting means is formed by press molding the short arm around the pivot between the short arm and the shoji mounting plate. A stopper step formed by press-molding the shoji mounting plate around the pivot is bent, and the second rotation restricting means is formed by press-molding the shoji mounting plate. The stopper is formed on the side surface of the long arm by press molding, and the stopper protrudes on both side surfaces of the long arm in the pivotal direction between the shoji mounting plate and the long arm. Formed on both sides of the long arm The protruding portion of the substantially H shape formed by connecting the connecting portion of the stopper section was made and characterized by being formed by press molding.

According to such a configuration, since the rotation exceeding the fully open position of the short arm and the shoji attaching plate is restricted by the turning restricting means provided between the short arm and the shoji attaching plate, the shoji in the fully open position is used. On the other hand, when a large wind pressure acts in the direction of opening the shoji due to gusts, for example, no moment is generated around the pivot (fulcrum) connecting the short arm and shoji mounting plate as in the conventional sliding window stay. A moment is generated around the pivot on the base end side of the short arm connecting the window frame mounting member and the short arm.

Accordingly , since the magnitude of the force acting on the long arm via the second rotation restricting means close to the fulcrum is significantly smaller than that of the conventional sliding window stay, the thickness should be reduced as much as possible. The torsional stress generated in the long arm that needs to be thinned and is relatively long and further formed with a bending portion for preventing interference can be greatly reduced.
Therefore, since the wind pressure at which the long arm whose strength is relatively weak due to the shape restriction or the like is plastically deformed can be increased, the wind pressure strength can be improved.

Furthermore, the rotation restricting means, said to those stopping step portion the formed by press molding the short arm about pivot of the short arm and shoji mounting plates, folded by press molding the shoji mounting plate about said pivot since was bent formed contact-stopping piece is to abutting-stops, since it constitutes a rotation restricting means with a simple configuration without an increase in the number of components, it is possible to suppress an increase in cost.
Furthermore, the second rotation restricting means abuts a stop portion formed by press molding on the side surface of the long arm to a stop step portion formed by press molding on the shoji mounting plate. Since the second rotation restricting means can be configured with a simple configuration that does not increase the number of parts, an increase in cost can be suppressed.

In addition, the stopper part is formed on both side surfaces of the long arm by press molding so as to protrude in the pivotal direction between the shoji mounting plate and the long arm, and connects the stopper parts on both side surfaces of the long arm. Since a substantially H-shaped projecting portion is formed by connecting the portions , when a large impact force is applied due to rattling due to fluctuations in wind pressure, this impact force is shared by the two rotation restricting means and the short arm In addition, the long arm can be firmly supported, and the plastic deformation of the long arm can be suppressed by the reinforcing effect by the substantially H-shaped protrusion.

Suberidashi window according to the present invention are those having the Suberidashi window stay.

As described above, according to Suberidashi window having a Suberidashi window stay and the stay according to the present invention, while suppressing increase in cost with a simple structure, relatively strong is weakened length constraints, etc. of the shape Since the wind pressure at which the arm is plastically deformed can be increased, the wind pressure strength can be improved.

Can be wiped clean.

Next, the configuration of the sliding window stay 1 will be described. As described above, the upper and lower stays 1 and 1 shown in FIG. 1 are symmetric with respect to the horizontal plane, and since these have the same configuration, only the configuration of the lower stay 1 will be described below.
As shown in FIGS. 1 to 4, the lower stay 1 is attached to the lower horizontal frame FL and has a substantially U-shaped cross section having a U-shaped opening 2 </ b> A that is long in the left-right direction and opens forward (outdoor OD). The window frame mounting material 2, the guide member 3 mounted in the U-shaped opening 2A of the window frame mounting material 2, and the short arm 4 having one end portion 4a pivotally attached to the one end portions 2a and 2b of the window frame mounting material 2. One end portion 5a is pivotally attached to the other end portion 4b of the short arm 4, and the shoji attachment plate 5 is attached to the lower heel DL of the shoji DR, and the one end portion 6a is one end portion 5a and the other end of the shoji attachment plate 5. The other end portion 6b is pivotally attached to an intermediate portion 5b with the portion 5e, and the other end portion 6b is constituted by a planar four-bar linkage mechanism including a long arm 6 pivotally attached to the other end portions 2c and 2d of the window frame mounting member 2.

The window frame attaching member 2 is made of, for example, stainless steel, and a guide member 3 made of, for example, a synthetic resin such as nylon or polyacetal is attached to the U-shaped opening 2A that opens forward.
Further, through holes 2a and 2b in the vertical direction are formed in one end portion of the window frame mounting member 2 (right end portion when viewed toward the outdoor side OD), and one end portion (right end portion) of the guide member 3 is formed in one end portion (right end portion). The vertical through holes 3a and 3b are formed at positions corresponding to the through holes 2a and 2b of the window frame mounting member 2.
Further, through-holes 2c and 2d in the vertical direction are formed at the other end of the window frame mounting member 2 (left end when viewed toward the outdoor side OD), and the other end (left end) of the guide member 3 is formed. The upper and lower direction through holes 3c and 3d are formed at positions corresponding to the through holes 2c and 2d of the window frame mounting member 2.
The window frame attaching material 2 is fixed to the lower horizontal frame FL of the window frame FR using the left and right window frame attaching long holes 2e and 2f.

  The short arm 4 is made of, for example, stainless steel, and the opening of the guide member 3 so that the through hole 4a at one end thereof is aligned with the through holes 2a, 2b, 3a, 3b of the window frame mounting member 2 and the guide member 3. 3A (refer to FIG. 3) is inserted into the stepped rivet 11, which is a pivot, through the holes 2a, 3a, 4a, 3b, 2b, and the shaft end is swaged, so that one end of the short arm 4 becomes a window frame. It is connected to one end of the mounting member 2 so as to be rotatable around a vertical axis.

The shoji mounting plate 5 is made of, for example, stainless steel, and a spacer (washer) made of synthetic resin such as nylon or polyacetal is provided between the through hole 5a at one end thereof and the through hole 4b at the other end of the short arm 4. ) The stepped rivet 12, which is a pivot, is connected to the through hole 8 a of the spacer 8, the through hole 5 a of one end of the shoji mounting plate 5, the through hole 7 a of the spacer 7, and the other end of the short arm 4. One end of the shoji mounting plate 5 is connected to the other end of the short arm 4 so as to be rotatable about the vertical axis by passing the shaft end through the through hole 4b.
The shoji attaching plate 5 is fixed to the lower lateral DL of the shoji DR using the shoji attaching holes 5c, 5d, 5e formed at, for example, three locations in the longitudinal direction.

  The long arm 6 is made of, for example, stainless steel, and a through hole 5b positioned between the through hole 6a at one end thereof, the through hole 5a at one end of the shoji mounting plate 5 and the shoji mounting hole 5e at the other end. The stepped rivet 13 serving as a pivot is connected to the through hole 9a of the spacer 9 and the through hole 6a at one end of the long arm 6 through spacers (washers) 9 and 10 made of synthetic resin such as nylon or polyacetal. By passing the shaft end through the through hole 10a of the spacer 10 and the through hole 5b of the shoji attaching plate 5, the one end of the long arm 6 is between the one end and the other end of the shoji attaching plate 5. It is connected so as to be rotatable around a vertical axis.

  The long arm 6 has an opening 3B (see FIG. 3) of the guide member 3 such that the through hole 6b at the other end is aligned with the through holes 2c, 2d, 3c, 3d of the window frame mounting member 2 and the guide member 3. And the other end of the long arm 6 is attached to the window frame mounting member 2 by crimping the shaft end through the stepped rivet 14 which is a pivot through the holes 2c, 3c, 6b, 3d and 2d. The other end is connected to be rotatable about a vertical axis.

  The short arm 4, the shoji attaching plate 5 and the long arm 6 shown in FIG. 3 are made into the window frame by the plane four-bar linkage mechanism including the window frame attaching material 2, the short arm 4, the shoji attaching plate 5 and the long arm 6 as described above. Between the state in which the shoji DR overlapped along the attachment material 2 is closed and the fully opened state of the shoji DR in which the short arm 4 and the shoji mounting plate 5 shown in FIGS. Can be opened and closed stably and reliably.

  When rotating the short arm 4, the shoji attachment plate 5 and the long arm 6 of the stay 1, which is a planar four-bar linkage mechanism, from the fully open state of the shoji DR shown in FIG. 2 to the closed state of the shoji DR shown in FIG. The upper horizontal plate of the window frame mounting member 2 is formed with a notch 2B, the guide member 3 is formed with a step 3C, and the long arm 6 is formed with a bent portion 6A in the middle in the longitudinal direction thereof. Therefore, since the window frame mounting member 2 and the guide member 3 do not interfere with the long arm 6, the short arm 4, the shoji mounting plate 5 and the long arm 6 shown in FIG. The overlapping shoji DR can be closed, and in this state, the shoji DR is stored in the window frame FR.

When the shoji DR is opened from the state in which the shoji DR shown in FIG. 3 is closed, the short arm 4 and the long arm 6 are rotated counterclockwise (see the arrow CCW in the drawing) as shown in FIG. When the mounting plate 5 is rotated clockwise (see arrow CW in the figure) and rotated to the fully open state of the shoji DR shown in FIG. 6, the short arm 4 and the shoji mounting plate 5 are substantially straight to the outdoor side OD. It becomes an extended state.
In the fully opened state of the shoji DR, the rotation restricting means A for restricting the turning of the short arm 4 and the shoji attaching plate 5 in the direction is provided between the short arm 4 and the shoji attaching plate 5, The second rotation restricting means B that restricts the shoji mounting plate 5 and the long arm 6 from rotating in the above direction is provided between the shoji mounting plate 5 and the long arm 6. The counterclockwise rotation of the arm 6 (see the arrow CCW in the figure) and the clockwise rotation of the shoji mounting plate 5 (see the arrow CW in the figure) are restricted.

  Here, the rotation restricting means A includes a stopper step 16 formed on the short arm 4 around the pivot axis 12 by press molding, and a stopper piece 16 formed on the shoji attachment plate 5 by bending around the pivot axis 12 by press molding. (See also FIG. 7.) The second rotation restricting means B is provided on the side of the long arm 6 on the stopper step 17 formed around the pivot 13 by press molding on the shoji attachment plate 5. Since the stop portion 18 formed by press molding is stopped, the rotation restricting means can be configured with a simple configuration that does not increase the number of parts, and thus an increase in cost can be suppressed.

  In addition, in order to share the long arm 6 in the upper stay and the lower stay, the long arm 6 is provided with a similar stopper 19 on the other side as well as a stopper 18 on one side thereof. These stoppers 18 and 19 are connected by a connecting part 20 to form a substantially H-shaped (e-shaped) projecting part in plan view. Therefore, the plastic deformation of the long arm 6 is suppressed by the reinforcing effect by the protrusion part which protrudes in the direction of the pivot 13 between the shoji attachment plate 5 and the long arm 6.

Further , by providing the second rotation restricting means B together with the rotation restricting means A, when a large impact force is applied due to rattling due to fluctuations in wind pressure, the impact force is shared by the two rotation restricting means A and B. Thus, it can be firmly supported by the short arm 4 and the long arm 6.

According to the configuration as described above, the rotation restricting means A provided between the short arm 4 and the shoji attachment plate 5 restricts the rotation beyond the fully open position of the short arm 4 and the shoji attachment plate 5. When a large wind pressure is applied to the shoji DR in the fully open position in a direction to open the shoji DR due to, for example, a gust of wind, the pivot 12 connecting the short arm 4 and the shoji mounting plate 5 as in the conventional sliding window stay. No moment is generated around, and a moment is generated around the pivot 11 on the proximal end side of the short arm 4 connecting the window frame mounting member 2 and the short arm 4.

Therefore , the magnitude of the force acting on the long arm 6 via the second rotation restricting means B close to the pivot 12 is significantly smaller than that of the conventional sliding window stay. The torsional stress generated in the long arm 6 where the bending portion 6A for preventing interference is formed can be significantly reduced.

Therefore, since the wind pressure at which the long arm 6 whose strength is relatively weak due to the shape restriction or the like is plastically deformed can be increased, the wind pressure strength can be improved.
