Description

  The present invention relates to a fitting including a frame and a face member that is rotatably supported by the frame and can be opened and closed.

2. Description of the Related Art Conventionally, a window stay that stops a shoji in an intermediate state between a fully closed state and a fully open state in a joinery including a window frame and a shoji that is rotatably supported by the window frame and can be opened and closed is known. (For example, refer to Patent Document 1).
The window stay described in Patent Document 1 includes a long base attached to a window frame, a slider attached slidably back and forth along the base, a shoji attaching plate attached to the shoji, It consists of five members, 1 and a second arm. One end of the first arm is rotatably connected to the slider, and the other end is rotatably connected to one end of the shoji mounting plate. One end of the second arm is rotatably connected to the end of the base on the retreat side, and the other end is rotatably connected to the other end of the shoji mounting plate.

However, in the window stay described in Patent Document 1, the structural members rotate with respect to each other during the opening / closing operation, so that the polygonal shape is surrounded by the base, the first arm, the shoji mounting plate, and the second arm. Therefore, there is a possibility that a finger is pinched by a portion surrounded by the base, the first arm, the shoji mounting plate, and the second arm.
Further, the first arm and the second arm are exposed between the window frame and the shoji when the shoji is opened during the opening / closing operation, so that the window stay can be seen from the indoor side. There was a problem that a good appearance could not be obtained.
Furthermore, the window stay described in Patent Document 1 has a large number of constituent members, a complicated structure, and a problem in terms of manufacturing cost.

  An object of the present invention is to provide a fitting capable of obtaining good operability and a good appearance and suppressing manufacturing costs.

  The joinery of the present invention is a joinery comprising a frame body and a face material that is rotatably supported by the frame body and can be opened and closed. When the face material is opened to the frame body by a predetermined angle, There is provided a regulating member that is slidably supported between the insertion position inserted into the gap between the face material and the frame body and the retracted position retracted from the gap, and the face material is provided at a predetermined angle. In the opened state, the regulating member slid to the insertion position abuts against the face material, so that the rotation of the face material in at least one direction is restricted.

According to the present invention, the restriction member is slidably supported by the frame body, and the restriction member abuts the face material only by inserting the restriction member into the gap between the frame body and the face material. The rotation can be restricted. Therefore, unlike a conventional window stay, there is no possibility of a finger being pinched between members that rotate with each other during opening and closing operations, and good operability can be obtained.
Further, since the restricting member is slidably supported by the frame body, the member is not exposed between the frame body and the face material according to the opening / closing operation of the face material as in the prior art. It is inconspicuous and a good appearance is obtained.
Further, in the conventional window stay, since a member such as an arm is pulled or bent, it is necessary to manufacture the member with a material having high rigidity (for example, stainless steel). Then, since the rotation of the face material is regulated by the contact between the face material and the regulating member, the regulating member is not subjected to tension or bending, and the regulating member is made of a material having lower rigidity than the conventional material (for example, synthetic resin). Can be manufactured. In addition, the restriction member can be simply configured to be slidably supported between the insertion position and the retracted position, the number of necessary parts can be reduced, and the manufacturing cost can be reduced.

In this case, in the joinery of the present invention, it is preferable that the restricting member is formed substantially parallel to a plane orthogonal to the prospective direction of the frame body and has a contact surface that contacts a predetermined portion of the face material.
According to this configuration, since the contact surface is formed substantially parallel to a plane perpendicular to the expected direction of the frame, when the contact surface and the predetermined portion of the face material contact each other, the contact surface is expected. Since the force in the direction orthogonal to the direction does not act, the regulating member does not move in that direction, and the rotation of the face material can be reliably regulated.

Furthermore, in the joinery of the present invention, the face material includes a plurality of surfaces that can be brought into contact with the contact surface of the regulating member and are substantially parallel to a plane orthogonal to the prospective direction of the frame body at every predetermined opening angle of the face material. It is preferable that rotation of the face material is regulated at a plurality of open angles by providing a contact surface of the contact surface and contacting the contact surface with any one of the plurality of contact surfaces.
According to this configuration, the contacted surface is provided so as to be able to contact the contact surface of the restricting member at a predetermined opening angle of the face material. The contact surface and the contact surface contact each other, and the rotation of the face material is restricted. Therefore, since an external force for rotating the face material can be received between the contact surface and the contacted surface, the face material and the contact material are compared with the case where the contact portion is in point contact or line contact. The durability of the contact portion of the regulating member is improved.
In addition, since the contact surface and the contacted surface are provided so as to be substantially parallel to a plane orthogonal to the prospective direction of the frame body, the surfaces that contact each other are restricted when the rotation of the face material is restricted. Relative movement in the direction parallel to the surface can be made difficult, and wear of the abutting surface hardly occurs. Therefore, the durability of the contact portion between the face material and the regulating member is improved as compared with the case where the rotation of the face material is regulated by friction between the contact surfaces.
In addition, since a plurality of contacted surfaces are provided for each predetermined opening angle (for example, 45 °, 90 °, etc.) of the face material, the rotation of the face material can be regulated by a plurality of opening angles. .

In the joinery of the present invention, the contact surface of the restricting member is formed across a point that passes through the rotation center of the face material and intersects with a line parallel to the prospective direction of the frame body in the state of being slid to the insertion position. And it is preferable that rotation of the said face material is controlled because a face material contact | abuts to a contact surface in at least two places straddling the crossing point.
According to this configuration, the contact surface is formed across the point passing through the center of rotation of the face material and intersecting with the line parallel to the prospective direction of the frame body, that is, orthogonal to the prospective direction from the intersecting point. Since it is extended on both sides in the direction, when the contact surface comes into contact with a predetermined portion of the face material, the regulating member and the face material come into contact with each other at at least two points across the intersecting point. Therefore, it is possible to restrict the rotation of the face material in both directions to open and close from a predetermined opening angle, and the face material can be held in the state of the opening angle. As for the contact between the contact surface and the face material in at least two places across the point, the contact surface portion on the face material side is formed by the surface straddling the point, and the surface of the contact surface and the face material It may be a contact.

Furthermore, in the joinery of the present invention, the contact surfaces of the restricting member are provided at a plurality of positions having different prospective direction positions, and the surface material rotates at a plurality of opening angles by contacting the plurality of contact surfaces. Is preferably regulated.
According to this configuration, even if the position where the face material abuts changes in the prospective direction position depending on the opening angle, the contact surface of the restricting member is provided at a plurality of positions with different prospective direction positions. The face material and the regulating member can be brought into contact with each other at the opening angle, and the rotation of the face material can be regulated at a plurality of opening angles.
In addition, by providing a plurality of contact surfaces on the regulating member side instead of the face material, it is necessary to process the surface material wrinkles or use a new member in order to form a contact surface on the face material side There is no need to prepare only a single part of the regulating member. Accordingly, the rotation of the face material can be regulated with a simpler configuration.

In the joinery of the present invention, it is preferable that the restricting member includes a base fixed to the frame body and a slide body that is slidably provided on the base and can come into contact with the face material.
According to this configuration, the restriction member is composed of the base fixed to the frame and the slide body that is slidably provided on the base and can come into contact with the face material. It is not necessary to form the guide portion to be formed on the frame body, and it is only necessary to fix the base to the frame body. Moreover, since processing of a frame becomes unnecessary, it can also be attached by retrofit to the existing joinery etc.

The first abutted surface 331 and the finding surface 332 are connected by a second abutted surface 335 that is an inclined surface of 45 degrees.

  The sliding body 12 of the restricting member 10 is in the retracted position with respect to the base 11 (the position at which the above-described protruding portion 14 is not locked to the locking portion 15) with respect to the vertical rod 33 on the hanging base side having such a configuration. Is set. In the retracted position, the first contact surface 16 of the slide body 12 is on the indoor side with respect to the finding surface 332 of the vertical rod 33, and the second contact surface 17 is on the inner side in the finding direction with respect to the prospective surface 333. ing. In this way, the shoji 3 and the regulating member 10 do not interfere with each other, and the shoji 3 can be rotated in the opening direction.

FIG. 5A shows a state in which the shoji 3 is opened to 45 ° with the slide body 12 of the restricting member 10 in the retracted position, and the second contact surface 335 of the shoji 3 is the groove 54.

It has become.
FIG. 5B shows a state in which the slide body 12 of the regulating member 10 is slid to the insertion position. This insertion position is a position where the above-mentioned protrusion 14 is locked to the locking portion 15 by sliding the slide body 12 to the suspending side in the direction of finding. That is, the slide body 12 is inserted into the gap between the second contact surface 335 of the shoji 3 and the inner surface 55 of the groove portion 54, and the second contact surface 335 and the first contact surface 16 are in contact with each other. It has become. Here, P indicates the rotation center of the shoji 3. L indicates a line passing through the rotation center P and parallel to the prospective direction of the window frame 2. C indicates a point where the first contact surface 16 and the line L intersect. The first contact surface 16 extends across the point C on both sides along the direction of finding. In this manner, the second contacted surface 335 contacts the first contact surface 16 in the predetermined region W2 straddling the point C, and the pivoting of the shoji 3 in both the opening and closing directions is restricted.

Next, FIG. 6A shows a state in which the shoji 3 is opened to 90 ° with the slide body 12 of the regulating member 10 in the retracted position, and the first abutting surface 331 of the shoji 3 is shown.

As shown in FIG. 6B, the second contact surface 17 is in contact with the second contact surface 17 in the predetermined region W4 on the inner side in the prospective direction with respect to the line L. It is like that. Thus, when the shoji 3 rotates in the closing direction, the second abutting surface 17 and the first abutted surface 331 come into contact with each other so that the pivoting of the shoji 3 in the closing direction is restricted. It has become.

  Next, a method for attaching the regulating member 10 will be described. Since the restricting member 10 includes the base 11 and the slider body 12, the window frame 2 can be attached in advance at a predetermined position when the window frame 2 is assembled at the assembly factory. Moreover, after fixing the window frame 2 to the opening part of an outer wall in the construction site of the single swing window 1, it is also possible to fix to a predetermined position. Further, it can be added to the existing single-sided window 1 and attached.

According to this embodiment, the following effects can be obtained.
(1) The restricting member 10 is slidably supported by the window frame 2, and the restricting member 10 contacts the shoji 3 only by inserting the restricting member 10 into the gap between the window frame 2 and the shoji 3. The rotation of the shoji 3 can be restricted by contact, and good operability can be obtained.
(2) Since the regulating member 10 is slidably supported by the window frame 2, the regulating member 10 is not exposed between the window frame 2 and the shoji 3 according to the opening / closing operation of the shoji 3, and the regulating member 10 is not conspicuous and a good appearance is obtained.

(3) Since the rotation of the shoji 3 is regulated by the contact between the shoji 3 and the regulating member 10, the regulating member 10 can be made of a synthetic resin without any tension or bending acting on the regulating member 10. Cost can be reduced.
(4) Since the first and second contact surfaces 331 and 335 are provided so as to be in contact with the first and second contact surfaces 16 and 17 of the regulating member 10 at a predetermined opening angle of the shoji 3. When the restricting member 10 is in the insertion position, the first and second contact surfaces 331 and 335 and the first and second contact surfaces 16 and 17 come into contact with each other, and the shoji 3 rotates. Be regulated. Accordingly, an external force for rotating the shoji 3 is applied to either the first contact surface 16 and the second contacted surface 335 or between the second contact surface 17 and the first contacted surface 331. Therefore, the durability of the contact portion between the shoji 3 and the regulating member 10 is improved.

(5) The first and second contact surfaces 16 and 17 and the first and second contacted surfaces 331 and 335 are provided so as to be substantially parallel to a plane orthogonal to the prospective direction of the window frame 2. Therefore, when the rotation of the shoji 3 is restricted, the abutting surfaces can be made difficult to move relative to each other in a direction parallel to the surface, and wear of the abutting surfaces hardly occurs. Therefore, the durability of the contact portion between the shoji 3 and the regulating member 10 is improved.

(6) When the shoji 3 has an opening angle of 45 °, the first contact surface 16 straddles the point C that passes through the rotation center P of the shoji 3 and intersects the line L parallel to the prospective direction of the window frame 2. Formed, i.e., extending from the intersecting point C to both sides in the direction perpendicular to the prospective direction, when the first contact surface 16 contacts the second contacted surface 335 of the shoji 3, The regulating member 10 and the shoji 3 come into contact with each other in a predetermined area W2 that crosses the intersecting point C. Accordingly, it is possible to restrict the pivoting in both directions in which the shoji 3 opens and closes from a predetermined opening angle, and the shoji 3 can be held at the opening angle.
(7) When the shoji 3 has an opening angle of 90 °, the second abutting surface 17 abuts on the first abutted surface 331, whereby the pivoting of the shoji 3 in the closing direction can be restricted.

(8) Even if the expected direction positions of the first and second contacted surfaces 331 and 335 change depending on the opening angle, the first and second contact surfaces 16 and 17 of the regulating member 10 have different expected direction positions. Since it is provided in a plurality of positions, the shoji 3 and the regulating member 10 can be brought into contact with each other at each opening angle, and the rotation of the shoji 3 can be regulated at a plurality of opening angles.
(9) Since the regulating member 10 includes a base 11 fixed to the window frame 2 and a slide body 12 that is slidably provided on the base 11 and can come into contact with the shoji 3, It is only necessary to fix to the frame 2, and the processing of the window frame 2 becomes unnecessary. In addition, the regulating member 10 can be attached to an existing joinery or the like by retrofitting.

Next, a half-opening window 1A according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a vertical cross-sectional view showing the single case window 1A. 8A and 8B are cross-sectional views illustrating the free state and the locked state of the shoji 3 in a state where the shoji 3 is opened by 45 °.
In FIG. 7, the one-sided window 1 </ b> A has a configuration in which the regulating member 10 is provided not only on the lower frame 5 but also on the upper frame 4 with respect to the one-sided window 1 of the first embodiment described above. This is different from the configuration provided at the intermediate height position of the vertical frame 6 on the hanging base side, and the other configurations are substantially the same. The restriction member 10 </ b> A is fixed to the inner side surface 45 of the groove portion 44 of the upper frame 4, similarly to the groove portion 54 of the lower frame 5.

  As shown in FIG. 8, the restricting member 10 </ b> A includes a synthetic resin base 11 </ b> A and a synthetic resin slide body 12 </ b> A that is slidably provided on the base 11 </ b> A. The base 11A is screwed to the inner side surface 61 of the vertical frame 6 with two screws 13A so that the guide direction of the slide body 12A is the direction in which the window frame 2 is found. The slide body 12 </ b> A has a first contact surface 16 and a second contact surface 17 similar to the slide body 12 of the first embodiment, and also has a knob portion 20. The user can slide the slide body 12A relative to the base 11A by pushing and pulling the knob portion 20 in the direction of finding.

According to this embodiment, in addition to the effects substantially the same as the effects (1) to (9), the following effects can be achieved.
(10) Since the restricting member 10 is attached to a total of three locations of the intermediate frame height of the upper frame 4 and the lower frame 5 of the shoji 3 and the vertical frame 6 on the hanging side, the rotation of the shoji 3 is surely restricted. can do.
(11) Since the knob portion 20 is provided on the slide body 12A, the slide body 12A can be easily slid by operating the knob portion 20.

[Third Embodiment]
Next, a single window 1B according to a third embodiment of the present invention will be described with reference to FIG. FIG. 9 shows a mechanism in which the shoji 3 is placed in a free state and a locked state using the regulating member 10B in each of the closed state, 45 ° opened state, 60 ° opened state, and 90 ° opened state. FIG.
As shown in FIG. 9, the single-opening window 1 </ b> B has a third contact surface 336 formed on the vertical rod 33 on the hanging side of the shoji 3 with respect to the single-opening window 1 of the first embodiment described above. And the configuration of the contact surface 16A formed on the slide body 12B of the regulating member 10B are different, and the other configurations are substantially the same.
That is, the third abutted surface 336 is formed between the first abutted surface 331 and the second abutted surface 335, and the third abutted surface is in a state where the shoji 3 is opened to 60 °. 336 is substantially parallel to the inner surface 55 of the groove 54. Then, in a state where the slide body 12B is slid to the insertion position, the third contacted surface 336 and the contact surface 16A of the slide body 12B come into contact with each other, and the rotation of the shoji 3 in both the opening and closing directions is restricted. It is like that.
The first, second, and third contact surfaces 331, 335, and 336 are formed so that the distance from the pivot center P of the shoji 3 is the same. As a result, the distance between each contacted surface 331, 335, 336 and the inner surface 55 of the groove portion 54 is the same in each opening angle of the shoji 3 (45 °, 60 °, 90 °), and The contact surfaces 331, 335, and 336 are configured to be able to contact the contact surface 16A of the slide body 12B. As described above, the slide body 12B is formed with the contact surface 16A that can contact the shoji 3 in any of the three open angles (45 °, 60 °, 90 °).

According to this embodiment, in addition to the effects substantially the same as the effects (1) to (9), the following effects can be achieved.
(12) The rotation of the shoji 3 can be restricted by the restricting member 10B in the three opening angles (45 °, 60 °, 90 °) of the shoji 3.
(13) Since the prospective direction positions of the first, second, and third contact surfaces 331, 335, and 336 do not change at the three opening angles, the contact surface 16A that is common to the slide body 12B of the restricting member 10B is one. Since it is sufficient to form only one, the structure of the restricting member 10B can be simplified.

In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, in the above-described embodiment, the single-opening window 1 is illustrated and described as a joinery. However, the joinery of the present invention is not limited to the single-opening window 1, but is a protruding window, a double-opening window, an external fall window, and an internal fall window. A window such as a skylight may be used. Or it is not restricted to a window, A front door etc. may be sufficient. Moreover, there is no restriction | limiting also in the attachment position and number of a control member.

The restricting member of the present invention is not limited to use for joinery, and is also used as a restricting member for restricting the rotation of a face material (for example, a door of a cupboard) that is rotatably supported by a support. it can.
In addition, in the existing one-sided window, a contact surface that can contact the shoji is formed on the restricting member at a predetermined opening angle of the shoji without changing the shape of the vertical hook on the side of the shoji hanging side. You may do it. Accordingly, it is not necessary to newly form a contact portion such as a vertical shaft of the shoji, and the rotation of the shoji can be restricted only by preparing a single component of the restricting member.

  Further, in each of the above embodiments, the case where the rotation of the shoji is restricted by the contact between the contact surface and the contacted surface is not limited to this. By providing one or a plurality of protrusions, the contact between the shoji side and the regulating member side may be the contact between the surface and the protrusion.

It is a longitudinal section showing a fitting concerning a 1st embodiment of the present invention. It is a cross-sectional view showing the joinery. It is a perspective view which shows the control member in the said fitting. It is a disassembled perspective view which shows the said limitation member. It is a cross-sectional view explaining a free state and a locked state in the state which opened the face material in the said fitting with 45 degrees. It is a cross-sectional view explaining the free state and locked state in the state which opened 90 degrees of the face materials in the said fitting. It is a longitudinal cross-sectional view which shows the fitting which concerns on 2nd Embodiment of this invention. It is a cross-sectional view explaining a free state and a locked state in the state which opened the face material in the said fitting with 45 degrees. It is a cross-sectional view explaining the free state and locked state of the face material in the fitting according to the third embodiment of the present invention.
