Description

  The present invention relates to an improvement of a window stay used for a sliding window or the like.

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 of their good sealing properties and the ability to wipe and clean both sides of the glass surface of the shoji from the indoor side. The sliding door is supported by a pair of left and right window stays so that it can be opened and closed with respect to the window frame.
As such window stays, there are those in which four pairs of planar four-bar linkage mechanisms are rotary pairs (for example, refer to Patent Documents 1 and 2), and since there is no linearly-moving pair (slider), the bite stays. It is characterized by being able to be opened and closed with a relatively small operating force.

Japanese Patent No. 3172348 Japanese Patent No. 38034949

The window stay as in Patent Document 1 is a frame mounting plate that is a flat plate made of stainless steel plate as a member to be attached to the window frame, and is relatively easy to manufacture. Since the support rigidity of the base end portion of the arm to which the load is applied is difficult to be sufficiently large, inconveniences such as the arm tilting from the base end portion and the shoji hanging may occur.
Further, in the window stay as in Patent Document 2, the member attached to the window frame is a U-shaped member having a vertical U-shaped section made of stainless steel plate, and the base end of the arm that is most loaded when the shoji is opened. Since the portion is sandwiched between the upper and lower horizontal wall portions of the U-shaped member, the structure is easy to make the support rigidity sufficiently large. The manufacturing cost is increased because it takes time and effort for press forming into a shape.

  Accordingly, in view of the above-described situation, the present invention provides a window stay that does not increase the manufacturing cost while having a configuration that can prevent inconvenience such as the hanging of the shoji caused by a decrease in rigidity. There is in point to do.

  In order to solve the above problems, a window stay according to the present invention includes a window frame mounting plate that is attached to a frame material of a window frame, a shoji mounting plate that is attached to a saddle member of a shoji, and a base end that is one end of the window frame mounting plate. A long arm plate that is pivotally attached to a portion or one end portion, and a distal end portion is pivotally attached between one end portion and the other end portion of the shoji attaching plate, and a base end portion is the other end of the window frame attaching plate Four pairs of planar four-bar linkage mechanisms, which are pivotally connected to the front or the other end, are composed of short arm plates that are pivotally attached to one end or one end of the shoji mounting plate. A window stay, wherein the window frame mounting plate, the long arm plate, and the short arm plate are press-formed products of a stainless steel plate, and the window frame mounting plate, the long arm plate, and the short arm plate are provided with reinforcing steps. Forming at least one of the pressing part and the step bending part by press molding And butterflies.

According to such a configuration, since the member attached to the window frame is a plate material (window frame attachment plate) that is a press-formed product of a stainless steel plate, the member attached to the window frame as in Patent Document 2 is made of a stainless steel plate. Compared to the U-shaped member having a U-shaped vertical cross section, the amount of relatively expensive stainless steel used can be reduced, and the pressing work for forming a U-shaped vertical cross section is required. Therefore, the manufacturing cost can be reduced.
In addition, since at least one of the reinforcing step pressing portion and the step bending portion is formed on the window frame mounting plate, when the shoji is opened as compared with the configuration of the flat plate material as in Patent Document 1. It is possible to increase the support rigidity of the base end portion of the arm plate that is most loaded.
Furthermore, since the long arm plate and the short arm plate are formed with at least one of the reinforcing step pressing portion and the step bending portion, the bending rigidity and the torsional rigidity can be increased.
Therefore, since the support rigidity, the bending rigidity, and the torsional rigidity are increased, it is possible to suppress inconveniences such as the long arm plate and the short arm plate being inclined and the shoji hanging and the window frame mounting plate, the long Since the reinforcing step pressing portion and the step bending portion formed on the arm plate and the short arm plate are formed by press molding, an increase in manufacturing cost can be suppressed.

Here, it is preferable that the shoji mounting plate is a press-formed product of a stainless steel plate, and at least one of a reinforcing stepped portion and a step bent portion is formed on the shoji mounting plate by press molding.
According to such a configuration, since at least one of the reinforcing step pressing portion and the step bending portion is also formed on the shoji mounting plate, the bending stiffness and torsional stiffness of the shoji mounting plate can be increased. The effect of suppressing inconvenience such as sagging is further enhanced, and the reinforcing stepped portion and the step bent portion formed on the shoji mounting plate are formed by press molding, so that an increase in manufacturing cost can be suppressed. .

In addition, it is preferable that an attachment hole formed in the window frame attachment plate for fixing the window frame attachment plate to the frame member is arranged closer to the indoor side than the indoor / outdoor center of the window frame attachment plate.
According to such a configuration, in a state in which the window frame mounting plate is fixed to the frame member, the fulcrum that supports the load of the shoji, which is the fixing position, is closer to the indoor side than the center of the window frame mounting plate in the indoor / outdoor direction. Therefore, because the length of the window frame mounting plate that exists in front of the fulcrum that supports the load of the shoji is long in the indoor and outdoor direction, it becomes difficult to fall down when a falling moment acts, so long arm plate and short arm plate However, the effect of suppressing inconvenience such as the shoji hanging from the base end portion is enhanced.

Further, in order to fix the window frame mounting plate to the frame material, two of the mounting holes formed in the window frame mounting plate are rotated in the outdoor direction with the shoji fully opened. It is preferable that the base end portion of the plate is disposed on both sides of the frame member in the longitudinal direction.
According to such a configuration, since the window frame mounting plate is fixed near the base end portion of the short arm plate that is rotated in the outdoor direction with the shoji fully opened and is most loaded, the window frame mounting plate is Since the fulcrum supporting the load of the shoji, which is the fixing position for fixing to the frame material, is located near the base end of the short arm plate to which the load is most applied, the load is applied in the fully open state of the shoji. Since the deformation between the fulcrum and the base end portion of the short arm plate is reduced, the effect of suppressing inconvenience such as the long arm plate and the short arm plate tilting from the base end portion and the shoji hanging down is further increased. Get higher.

  As described above, according to the window stay according to the present invention, the window frame mounting plate, the shoji mounting plate, the long arm plate, and the short arm plate are press-formed products of stainless steel plates, and the reinforcing stepped portion and step It is possible to prevent inconvenience such as sagging of the shoji caused by a decrease in rigidity by the configuration such as forming at least one of the bent portions by press molding, but the manufacturing cost does not increase. There are remarkable effects such as.

It is the perspective view seen from the outdoor side which shows the example which used the window stay concerning embodiment of this invention for the vertical sliding window, and has shown the full open state of the shoji. It is a partial vertical section right side view. It is a top view of the lower window stay similarly. Similarly, it is a plan view of the lower window stay, showing the fully closed state of the shoji. It is a perspective view of a window stay simple substance concerning an embodiment of the invention. It is an exploded perspective view similarly.

Examples of the window in which the window stay according to the present invention is used include a vertical sliding window, a horizontal sliding window, an inward window, and an outward window. In the following, the window in which the window stay according to the present invention is used. As an example, a vertical sliding window will be described.
In this specification, the front side in the direction from the indoor side (see ID in the figure) to the outdoor side (see OD in the figure) (see arrow F in the figure) is the front, the rear is the rear, Means forward, and the view from the indoor side is the front view.

As shown in the perspective view of FIG. 1, the window frame FR is composed of upper and lower horizontal frames FU and FL which are frame members and left and right vertical frames FS and FS. The shoji DR is composed of DU and DL and left and right vertical rods DS and DS, and is supported so as to be openable and closable with respect to the window frame FR by upper and lower window stays 1 and 1 formed symmetrically with respect to a horizontal plane. Thus, a vertical sliding window SW is formed.
With such a configuration, the shoji DR fully opened state shown in the perspective view of FIG. 1, the partially vertical right side view of FIG. 2, and the plan view of FIG. 4 can be opened and closed between the fully closed state of the shoji DR shown in the plan view of FIG. 4, and in the fully open state of the shoji DR, both surfaces of the glass surface G of the shoji DR (see FIG. 1). Can be wiped clean.

Since the upper and lower window stays 1 and 1 are symmetrical with respect to the horizontal plane, the lower window stay 1 will be described below.
As shown in the perspective view of FIG. 5 and the exploded perspective view of FIG. 6, the window stay 1 according to the embodiment of the present invention is attached to the frame material (horizontal frame FL) of the window frame FR and has a long window frame on the left and right. The mounting plate 2, the shoji mounting plate 3 that is attached to the saddle material of the shoji DR (the horizontal rail DL), and the base end portion (through hole 4 a) are pivoted toward one end portion or one end portion of the window frame mounting plate 2 (through hole 2 a). A long arm plate 4 that is attached and has a distal end portion (through hole 4b) pivoted between one end C1 and the other end portion C2 (through hole 3b) of the shoji mounting plate 3, and a base end portion (through hole). 5a) is pivotally attached to the other end of the window frame mounting plate 2 or near the other end (through hole 2b), and the distal end (through hole 5b) is closer to one end C1 or one end C1 of the shoji mounting plate 3 (long). The arm plate 4 includes a short arm plate 5 pivotally attached to a through hole 3a formed at a position closer to the one end C1 than a portion (3b) to which the tip portion is pivotally attached.
Here, the window frame mounting plate 2, the shoji mounting plate 3, the long arm plate 4 and the short arm plate 5 are press-formed products of stainless steel plates, and details of reinforcing step pressing portions 2A and 4A and step bending portions which will be described later. 3A and 5A are formed by press molding.

Next, details of the structure of the window stay 1 will be described mainly with reference to FIG.
Since the window frame mounting plate 2 is provided with mounting holes 8a, 8b, 8c in the longitudinal direction thereof, the mounting screws are used for the horizontal frame FL (see FIG. 1) using these mounting holes 8a, 8b, 8c. )), The window frame mounting plate 2 is mounted on the horizontal frame FL.
Further, since the shoji mounting plate 3 has mounting holes 9a, 9b, 9c, 9d in the longitudinal direction thereof, the mounting screws can be used with these mounting holes 9a, 9b, 9c, 9d. The shoji attaching plate 3 is attached to the recumbent DL by screwing into the DL (see FIG. 1).

With the through hole 4a drilled in the base end of the long arm 4 aligned with the upper side of the through hole 2a drilled near the left end of the window frame mounting plate 2, the pivot rivet 14 is passed from above. By caulking the shaft end, the base end portion (through hole 4a) of the long arm 4 is connected to the window frame mounting plate 2 so as to be rotatable about the vertical axis.
Further, with the through-hole 4b drilled in the distal end of the long arm 4 aligned with the lower side of the through-hole 3b drilled in the middle part of the shoji mounting plate 3, the pivot rivet 13 is viewed from below. The end of the long arm 4 (through hole 4b) is connected to the shoji mounting plate 3 so as to be rotatable about the vertical axis by caulking the shaft end.

Further, the through hole 5b formed in the tip of the short arm 5 has a through hole 7a in the spacer 7 below the through hole 3a formed near the one end C1 of the shoji mounting plate 3. The tip end portion (through hole 5b) of the short arm 5 is connected to the shoji attachment plate 3 so as to be rotatable around the vertical axis by passing the rivet 12 as a pivot from below and caulking the shaft end. .
Furthermore, the proximal end portion of the short arm 5 is inserted into the opening between the upper and lower plates of the guide member 6, and the through hole 6 a of the upper plate of the guide member 6 and the through hole 5 a formed in the proximal end portion of the short arm 5. In the state where the through hole 6b of the lower plate of the guide member 6 is aligned with the upper side of the through hole 2b drilled near the right end of the window frame mounting plate 2, the shaft end is passed through the pivot rivet 11 from above. By caulking, the base end portion (through hole 5a) of the short arm 5 is connected to the window frame mounting plate 2 so as to be rotatable about a vertical axis.

Since the upright piece 2c bent upward from the right end of the window frame mounting plate 2 is inserted into the slit 6f of the guide member 6, the guide member 6 is positioned with respect to the window frame mounting plate 2, and the guide member 6 is positioned. The upper and lower through holes 6a and 6b are aligned with the through hole 2b of the window frame mounting plate 2, and the upper and lower through holes 6c and 6d of the guide member 6 are aligned with the through hole 8b of the window frame mounting plate 2. At the same time, the through holes 6e of the guide member 6 and the through holes 8c of the window frame mounting plate 2 are aligned.
Here, the guide member 6 and the spacer 7 are made of synthetic resin such as nylon or polyacetal, for example.

Further, the window frame mounting plate 2 is formed with a turn restricting convex portion 10A protruding upward, and the shoji mounting plate 3 is formed with a turn restricting convex portion 10B protruding downward by press forming. Is formed.
Therefore, the shoji DR of the vertical sliding window SW is opened from the fully closed state of FIG. 4, and the window stay 1 is changed from the form shown in FIG. 4 to the fully shown state of the shoji DR shown in FIGS. Then, as shown in FIG. 3, the rotation restricting convex portion 10A comes into contact with the left side surface of the base portion of the short arm plate 5, and as shown in FIGS. Since the rotation restricting convex portion 10B comes into contact with the rear of the rivet 13 as described above, further turning of the shoji DR is restricted.

Next, the reinforcement structure of the window stay 1 for preventing inconvenience such as the hanging of the shoji DR will be described.
As shown in FIG. 6, the window frame mounting plate 2 has a portion extending in the left-right direction and a portion extending forward from the middle portion in the range of about 3/4 of the entire length from the through hole 8a to the through hole 8b. Since the reinforcing stepped portion 2A is formed by stepping by pressing, the bending rigidity and torsional rigidity of the window frame mounting plate 2 are improved.
Further, the shoji attaching plate 3 is formed with a reinforcing step bending portion 3A formed by step-bending the outer peripheral edge which is the rear side in the fully opened state of the shoji DR shown in FIG. 3 is improved in bending rigidity and torsional rigidity.
Further, the long arm plate 4 is formed with a reinforcing stepped portion 4A formed by pressing the intermediate portion in the width direction by press molding in a range extending from the base end side to about 2/3 of the entire length. Therefore, the bending rigidity and torsional rigidity of the long arm plate 4 are improved.
Furthermore, the short arm plate 5 is formed with a reinforcing step bent portion 5A formed by bending the side edge of the left and right sides by press molding in the fully opened state of the shoji DR shown in FIG. The bending rigidity and torsional rigidity of the arm plate 5 are improved.
The reinforcing structure formed by press molding on the window frame mounting plate 2, the shoji mounting plate 3, the long arm plate 4 and the short arm plate 5 is at least one of a stepped portion and a step bent portion, that is, a stepped portion and a stepped portion. What is necessary is just to provide one or both of the bending parts.

Further, as shown in FIG. 3, the positions of the mounting holes 8a, 8b, 8c formed in the window frame mounting plate 2 for fixing the window frame mounting plate 2 to the horizontal frame FL (frame material) are the window frame mounting positions. The board 2 is arranged behind (indoor) closer to the straight line L connecting the center of the length B in the front-rear direction (indoor / outdoor direction).
Further, two of the mounting holes 8a, 8b, 8c formed in the window frame mounting plate 2 for fixing the window frame mounting plate 2 to the horizontal frame FL (frame material) are fully opened by the shoji DR. The short arm plate 5 rotated forward (outdoor direction) in the state is disposed near (near) the left and right sides (both front and rear sides in the longitudinal direction of the horizontal frame FL) of the base end portion.

  In the above description, the window frame mounting plate 2, the shoji mounting plate 3, the long arm plate 4 and the short arm plate 5 are all press-formed products made of stainless steel plates. Although the configuration in which at least one of the portions 2A, 3A, 4A, and 5A is formed by press molding has been shown, a configuration in which a step pressing portion or a step bending portion is not formed on the shoji attachment plate 3 can also be adopted.

According to the configuration of the window stay 1 as described above, the member attached to the window frame FR is a plate material (window frame mounting plate 2) that is a press-formed product of a stainless steel plate. Compared with the configuration in which the member to be attached is a U-shaped member with a U-shaped longitudinal section made of stainless steel plate, the amount of relatively expensive stainless steel used can be reduced, and it is molded into a U-shaped longitudinal section. The manufacturing cost can be reduced because there is no need for press molding.
Further, since the reinforcing stepped portion 2A is formed on the window frame mounting plate 2, the bending rigidity and the torsional rigidity of the window frame mounting plate 2 are improved as described above. Compared with the structure which is a board | plate material, when the shoji DR is opened, the support rigidity of the base end part of the long arm board 4 and the end arm board 5 to which a load is most applied can be improved.
Further, since the reinforcing arm pressing portion 4A is formed on the long arm plate 4 and the reinforcing step bending portion 5A is formed on the short arm plate 5, the bending rigidity of the long arm plate 4 and the short arm plate 5 and Torsional rigidity is improved.
Therefore, since the support rigidity, the bending rigidity, and the torsional rigidity are increased, inconveniences such as the long arm plate 4 and the short arm plate 5 tilting and the shoji DR hanging down can be suppressed, and the window frame can be attached. Since the reinforcing step pressing portions and step bending portions 2A, 4A, and 5A formed on the plate 2, the long arm plate 4 and the short arm plate 5 are formed by press molding, an increase in manufacturing cost can be suppressed.

Furthermore, since the shoji mounting plate 3 is a press-formed product of a stainless steel plate and the reinforcing step bending portion 3A is formed on the shoji mounting plate 3, the bending stiffness and torsional stiffness of the shoji mounting plate 3 can be increased. For this reason, the effect of suppressing inconvenience such as hanging of the shoji DR is further enhanced, and the reinforcing step bending portion 3A formed on the shoji mounting plate 3 is formed by press molding, thereby suppressing an increase in manufacturing cost. Can do.
2 and 3, the mounting holes 8a, 8b, 8c formed in the window frame mounting plate 2 for fixing the window frame mounting plate 2 to the horizontal frame FL are provided on the window frame mounting plate 2. Since the window frame mounting plate 2 is fixed to the horizontal frame FL, the fulcrum that supports the load of the shoji DR, which is the fixed position, is the front and rear of the window frame mounting plate 2 because the window frame mounting plate 2 is fixed to the horizontal frame FL. Since it is behind the center of the direction (see the straight line L in FIG. 3), the length of the window frame mounting plate 2 existing in front of the fulcrum supporting the load of the shoji DR is longer and falls down. Since it becomes difficult to fall down when a moment acts, the effect of suppressing inconveniences such as the long arm plate 4 and the short arm plate 5 tilting from the base end portion and the shoji DR hanging down becomes high.
Further, two left and right sides of the base end portion of the short arm plate 5 in which two of the mounting holes 8a, 8b, 8c formed in the window frame mounting plate 2 are rotated forward in the fully opened state of the shoji DR. The window frame mounting plate 2 is fixed near the base end portion of the short arm plate 5 that rotates forward with the shoji DR fully opened and is loaded most. Since the fulcrum supporting the load of the shoji DR, which is a fixing position for fixing to the horizontal frame FL, is located near the base end portion of the short arm plate 5 to which the load is most applied, the shoji DR is fully opened. Since the deformation between the fulcrum and the base end portion of the short arm plate 5 when a load is applied is reduced, the long arm plate 4 and the short arm plate 5 are tilted from the base end portion and the shoji DR is suspended. The effect of suppressing the inconvenience is further enhanced.
