Description

  The present invention relates to a fixing bracket used for attaching a sash window frame to a building frame and a method of fixing the sash window frame using the fixing bracket.

  Conventionally, in order to attach a sash window frame to a building frame, the upper and lower horizontal frames and the left and right vertical frames constituting the window frame are joined to a base wall for holding joinery or fitting glass, and an outdoor side end portion of the base wall. And the imbedding wall extending in the direction away from the center of the window opening so as to have a substantially L-shaped cross section, and the fitting portion is formed at the outdoor side end of the fitting portion with a rectangular base wall. The imposition part is constituted by imposition walls continuous to each other, and the fitting part is fitted into a window opening formed in the building frame, and the imposition part is set to the outdoor side surface of the building frame, usually, A screw is screwed from each imposition wall into the window opening frame and fixed in a state where it is pressed against the outdoor side surface of the window opening frame that is integrally attached to the building frame.

In that case, the left and right pillars that constitute the outdoor side of the window opening frame and the outdoor side of the lintel do not always exist on a complete vertical plane, and there is a slight misalignment. The upper surface does not always form a complete horizontal surface, and usually has a slight inclination. Therefore, when attaching a window frame to a window opening frame having such a displacement or inclination, a wedge-shaped spacer (adjustment material) is inserted between the outdoor side surface of the window opening frame and the imposition wall of each frame, and Adjust the position in the indoor and outdoor directions so that the imposition wall is on one vertical surface, and at the same time, the same wedge-shaped spacer (adjustment material) between the base wall of each frame and the inner peripheral surface of the window opening frame After adjusting the position of each base wall in the left and right direction and up and down direction, screw the wood screw from the inner peripheral side of each frame to the window opening frame, and fix the window frame in a proper position at a predetermined position Yes.
Japanese Utility Model Publication No. 60-6555

In the prior art, as described above, between the window opening frame and the window frame, not only between the outdoor side surface of the window opening frame and the imposition wall of the window frame, but also the inner peripheral surface of the window opening frame and the window It is necessary to adjust the position of the window frame in the indoor / outdoor direction, up / down direction, and left / right direction and fix it between the base wall of the frame and the thickness of the spacer. Since it differs depending on the construction site, it took a lot of time to prepare the appropriate spacer, and it was not easy to insert the appropriate amount of spacer at the appropriate position on the site, and it took time to construct . This is because, firstly, a conventional window frame has an imposition wall, and the window frame is fixed to the window opening frame on the imposition wall, and secondly, the position adjustment function of the window frame to the spacer. This is due to having both functions of the fixed function.

The present invention has been made in view of the above points, and the first problem is easy adjustment of the position of the window frame in the left-right direction, the up-down direction, and the indoor / outdoor direction, and fixing the window frame after position adjustment. An object of the present invention is to provide a fixing bracket that can be used.
A second problem is to provide a method for fixing a window frame that allows the window frame to be quickly attached using the fixing metal fitting.

Fixing bracket sash window frame according to the present invention, for solving the above first object, consists of a (a) first fitting and the second fitting were both made by cutting and bending of the steel sheet, (b) The first metal fitting has a locking portion that is slidably locked in the longitudinal direction of each frame at both ends of the horizontal frame and the vertical frame of the window frame, and bends between both locking portions. is formed, and a first coupling portion extending from the engaging portion in a direction away from the window opening centered along the inclined surface of a predetermined angle relative to the longitudinal direction of each frame, (c) second bracket A fixing portion fixed to the outdoor side surface of the window opening frame with a first screw, and the first coupling extending from the fixing portion in an indoor direction along an inclined surface having a fixed angle with respect to a longitudinal direction of each frame. And (d) one of the first coupling portion and the second coupling portion has a long hole and the other. Each side is provided with a hole into which the second screw inserted into the long hole can be screwed, and (e) a pair of latches formed on the outer surface of the vertical frame or horizontal frame of the window frame. It is slidably inserted into a groove formed by an edge, and the locking edge of the vertical frame or the horizontal frame is temporarily connected to both the locking portion of the first metal fitting and the first coupling portion of the first metal fitting with a second screw. It is characterized in that it is attached to the window frame by being sandwiched between the second fitting part of the second metal fitting .

The fixing portion of the second metal fitting, it is desirable that the elongated hole having a major axis in the direction perpendicular to the longitudinal direction of the frame for penetrating the first screw is provided.

  The sash window frame fixing method according to the present invention includes: (a) the sash window frame fixing metal fittings at least near both ends in the longitudinal direction of the vertical frame and horizontal frame of the window frame; (B) A window frame is attached to the window opening frame by sandwiching and mounting between the latching portion of the metal fitting and the first coupling portion of the first metal fitting between the second coupling portion of the second metal fitting temporarily joined with the second screw. Are fitted to each other, the respective fixing portions of the second brackets of the respective fixing brackets are brought into contact with the outdoor side surface of the window opening frame, the position of the window frame is adjusted in the horizontal direction and the vertical direction, The first screw penetrating the long hole is screwed and fixed to the outdoor side surface of the window opening frame, and (c) the window frame is moved indoors and outdoors at least at the mounting position of each fixing bracket to adjust the position. 2 Tighten the screws completely to firmly connect the first bracket and the second bracket, and at the same time, the window frame to the left and right, up and down, indoors and outdoors It is characterized in that securing against.

According to the invention of claim 1, after adjusting the position of the window frame in the left-right direction and the up-down direction, the second metal fitting is fixed to the window opening frame with the first screw, and then the position of the window frame in the indoor / outdoor direction is adjusted. After that, by completely connecting the first and second brackets with the second screw, the horizontal frame and the vertical frame of the window frame can be fixed without troublesome position adjustment by a non-dimensional spacer and fixing with a wood screw. By the same adjustment work and joining work of the fixing hardware having substantially the same structure in both, it can be easily and efficiently fixed at an appropriate position, and the workability is remarkably improved.
In addition, since the first metal fitting and the second metal fitting are made by cutting and bending a steel plate, a fixing metal fitting having a required strength can be manufactured easily and inexpensively, and a fixing metal fitting is attached to the window frame. Therefore, since it is sufficient to secure a minimum space for the window frame, the size of the window frame in the direction of attachment is not increased, and the existing window opening frame can be used as it is.

According to the invention of claim 2 , when the window frame is attached, the position adjustment of the window frame can be performed in a state where the second metal fitting is first fixed to the window opening frame and the window frame is stable.

The sash window frame fixing method according to the invention of claim 3 is a method of mounting the fixing metal fittings at predetermined positions of the vertical frame and the horizontal frame of the fixing metal fittings, fitting the window frame to the window opening, the horizontal direction of the window frame, and Appropriate for the building body by fixing the second bracket after the vertical position adjustment with the first screw, and connecting the first and second brackets after adjusting the position of the window frame indoors and outdoors by the second screw It is possible to attach the sash window frame to a simple position quickly.

  When the present invention is implemented, no imposition wall is provided on the window frame. The fixing bracket is divided into a first bracket and a second bracket. The fixing metal fittings are attached to a plurality of locations separated in the longitudinal direction of the vertical frame and the horizontal frame constituting the window frame. The first metal fitting is, for example, a locking portion that is slidably locked in the longitudinal direction of each frame by a pair of locking edges or grooves on the outer surface of the base wall of each frame of the window frame, and its locking A first coupling portion extending from the portion in a predetermined direction with a constant inclination angle. The second metal fitting has a fixing portion fixed to the outdoor side surface of the window opening frame and a second coupling portion extending from the fixing portion in a predetermined direction with a certain inclination angle. The first metal fitting and the second metal fitting are screwed into a hole or screw hole provided in the other through a long hole provided in one of the first coupling portion and the second coupling portion extending along the same inclined surface. Thus, provisional bonding or main bonding is possible. In the temporarily coupled state, the first bracket and the second bracket can be moved relative to each other in the indoor / outdoor direction, in the horizontal direction in the vertical frame, and in the vertical direction in the horizontal frame. The second bracket is fixed to the outdoor side surface of the window opening frame, and after adjusting the position of the window frame in the left-right direction and the up-down direction and the position in the indoor / outdoor direction via each fixing bracket, the first bracket and the second bracket are adjusted with screws. By attaching the metal fittings completely, a plurality of fixing metal fittings having almost the same structure are attached to the required positions of the window frame in the same manner, and the position adjustment and the joining operations are performed in the same manner. The window frame can be fixed at an appropriate position of the window opening frame. That is, the present invention is characterized in that the adjustment of the position of the window frame with respect to the window opening frame and the fixing after the adjustment are performed separately by dividing the fixing bracket into the first bracket and the second bracket. .

It is advantageous to make the first metal fitting and the second metal fitting both by cutting and bending a steel plate in order to ensure the required strength and to realize inexpensive and easy production, and for mounting on the window frame. Since it is only necessary to form a thin space in the window, it is possible to easily secure a driver insertion gap for completely tightening the screw that joins the first metal fitting and the second metal fitting after adjusting the position of the window frame. Since the size of the frame in the direction of attachment is not increased, the existing window opening frame can be used as it is.
Below, a concrete structure and an effect | action are demonstrated in detail based on an Example.

It is an expanded view of the 2nd metal fitting which is a component, Comprising: (a) is a front view, (b) is a top view, (c) is a perspective view. 6 is a front view of a fixing metal fitting formed by joining two metal fittings, and FIG. 7 is a partially enlarged sectional view showing details of the fixing metal fitting attached to the vertical frame on the right side of FIG.

  1 and 2, reference numeral 1 denotes a window opening frame, which is constructed by connecting a lintel 11, a window base 12, and left and right pillars 13 and 14 in a rectangular shape, as in the prior art. Reference numeral 2 denotes a window frame, which is configured by connecting upper and lower horizontal frames 21 and 22 and left and right vertical frames 23 and 24 in a rectangular shape by using a conventional technique. However, unlike the conventional product, the window frame 2 according to the present invention has square cylindrical base walls 21w, 22w; 23w, 24w for holding the fittings or fitting glass, but the window opening frame 1 does not have an imposition wall imposed on the outdoor side surface. Thereby, after fitting a window frame to a window opening frame, it is possible to move within a limited range in the indoor and outdoor directions.

Then, on the outer surfaces of the frames 21, 22; 23, 24, that is, the surfaces opposite to the window opening center, locking edges 21a, 21b; 22a, 22b; , 23b; 24a, 24b are projected, and grooves 21c, 22c, 23c into which a locking portion of the first metal fitting 3A described later can be inserted between each pair of locking edges and the back surface of the base wall. , 24c are formed. The locking edges 21a, 21b,... 24a, 24b all have the same thickness. Further, at least one locking edge of the pair of locking edges is provided with a portion extending in the outward direction of each frame, that is, in the direction away from the opening center of the window frame, on the outside of the pair of locking edges. As will be described later, spaces 21d, 22d; 23d, 24d that are sufficient to accommodate the first coupling portion 33 and the second coupling portion 36 of the fixture are configured. For mounting stability enhancement with the inner circumference of the window opening frame 1 of 23, a pair of locking edge 21a, 21b;; each frame 21,22 22a, 22b; 23a, 23b ; 24a, within 24b Yorimoya Abutting edges 21e, 22e; 23e, 24e extending to the same distance as the extended ends of the locking edges are provided on the side.

  The upper and lower horizontal frames 21 and 22 and the left and right vertical frames 23 and 24 use the pairs of locking edges 21a and 21b to 24a and 24b and grooves 21d and 22d; The fixing bracket 3 is mounted in advance, that is, before the window frame 2 is attached to the opening frame 1. As shown in an example in FIG. 3, the fixing bracket 3 is provided at least in the vicinity of both ends in the longitudinal direction of each frame. It is provided near the center and in the middle position.

  The fixture 3 includes a first bracket 3A illustrated in FIG. 4 and a second bracket 3B illustrated in FIG. The first metal fitting 3A is made of a rigid metal plate, for example, a steel plate, has locking portions 32a and 32b extending in parallel to the left and right sides of the main body 31, and a plane connecting both locking portions therebetween. And has a belt-like first coupling portion 33 that extends to one side in the perpendicular direction and is inclined at a constant angle with respect to the parallel lines of the two locking portions. Although the specific value of the fixed angle is arbitrary, the example shown in the figure is 45 degrees with respect to the parallel lines of both locking portions.

  Although the manufacturing method of the 1st metal fitting 3A is not limited, if an example is demonstrated, a cutting line will be carried out to the distance of about 2/3 from the vicinity of one end of one side of a rectangular steel plate to the opposite side in the direction perpendicular to the one side. Provided, bend the triangular part connecting the both ends of the cut line and the vicinity of the other end of one side, along a straight line connecting the end point of the cutting line and the vicinity of the other end of the one side until it is perpendicular to the steel plate, The bent triangular portion is separated from the bent portion by a distance equal to the depth of the spaces 21d, 22d; 23d, 24d of the window frame 2, that is, the length of the extended portion of the locking edge of each frame. The trapezoidal first coupling portion 33 is formed by cutting. A substantially circular screw hole or a hole through which a screw can be screwed into the first coupling portion 33 in a direction perpendicular to the plane of the coupling portion (hereinafter simply referred to as a hole) is provided at the approximate center of the first coupling portion 33. 34 is formed.

  The second metal fitting 3B is also made of the same metal plate, for example, a steel plate, and a fixing portion 35 is formed on the lower side portion of the L-shape, and the first metal fitting is connected to the fixing portion 35 from either the left or right side of the fixing portion. A band-shaped second coupling portion 36 that is inclined at an angle equal to the angle of the first coupling portion 33, in the example shown, is 45 degrees. The width of the second coupling portion 36 is equal to the width of the first coupling portion 33 of the first metal fitting 3A. And the long holes 37 and 38 which can penetrate a screw | thread are respectively formed in the width direction center of the adhering part 35 and the 2nd coupling part 36 so that the longitudinal direction long axis of each coupling part may correspond.

  The first metal fitting 3A and the second metal fitting 3B can be coupled with one screw 4 (corresponding to the second screw) as illustrated in FIG. That is, the second coupling part 36 of the second metal fitting 3B is overlapped with the first coupling part 33 of the first metal fitting 3A shown in FIG. 4C, and the hole 34 and the second coupling part of the first metal coupling part 33 are overlapped. The first metal fitting 3A and the second metal fitting 3B are joined by matching the 36 long holes 38, inserting the screws 4 from the long holes 38, and screwing the screws 34 into the holes 34 by an appropriate amount. In this case, between the main body 31 of the first metal fitting 3A and the fixing portion 35 of the second metal fitting 3B, the thickness of the locking edge 21a, 21b-24a, 24b of the window frame WF is 0.05-0. The gap is formed so as to be narrow by about 10 mm. Further, by reducing the screwing amount of the screw 4, the first coupling portion 33 and the second coupling portion 36 can be relatively moved in the major axis direction of the long hole 38 and in the direction perpendicular to the major axis. The first metal fitting 3A and the second metal fitting 3B can be relatively moved in the left-right direction (corresponding to the indoor / outdoor direction of the window frame) and the vertical direction (corresponding to the height direction of the window frame or the left-right direction) in FIG. .

  4 to 6 is a vertical frame 24 on the right side of FIG. 2 (vertical frame 24 of FIG. 7), that is, a vertical frame on the right side of FIG. 3 showing the window frame WF viewed from the outdoor side. Although the shape of what is attached to the frame 24 is shown, the fixing bracket 3E attached to the left vertical frame 23 in FIG. 3 is made symmetrically with the fixing bracket 3 attached to the right vertical frame 24. The fixing brackets 3 'and 3'E attached to the upper and lower horizontal frames 21 and 22 in FIG. 3 are formed by inverting the right vertical frame fixing bracket 3 shown in FIGS. 4 and 5 to the left 90 degrees or the right 90 degrees. Used in

As for the mounting method of the fixing bracket having the above-described form with respect to the window bracket on the right side of FIG. 2, that is, attached to the right vertical frame of FIG. 3 showing the window frame WF viewed from the outdoor side. This will be described with reference to FIG.
In the rectangular window frame, the groove 24c of the vertical frame 24 is open at the upper and lower end surfaces of the vertical frame, so the first metal fitting 3A is inserted from either one or both ends of the groove, After moving from each end to a predetermined distance, the second coupling portion 36 of the second metal fitting 3B is superimposed on the upper surface of the first coupling portion 33 projecting outward from the groove 24c, and the screw 4 penetrating the elongated hole 38 is inserted. By loosely screwing into the hole 33, the pair of locking edges 24a, 24b of the vertical frame is sandwiched between the locking portions 32a, 32b of the first metal fitting 3A and the second coupling portion 36 of the second metal fitting 3B. Temporarily fix.

  On the other hand, since the grooves 21c and 22c of the upper and lower horizontal frames 21 and 22 are shielded by the base walls of the vertical frames 23 and 24, the first metal fitting 3A cannot be inserted into the grooves. Therefore, the locking edges 21a, 21b; 22a, 22b of the horizontal frame are cut out at arbitrary positions in the longitudinal direction of the horizontal frame to form a notch (not shown), and the pair of locking portions 32a of the first metal fitting are formed from the notch. 32b are inserted into the grooves 21c and 22c, and the first metal fitting 3A is moved from the longitudinal end of the horizontal frame to a predetermined position, and then the second metal fitting is attached to the first metal fitting 3A in the same manner as the vertical frame. 3B is temporarily joined with screws 4 and temporarily fixed to the horizontal frames 21 and 22.

  The fixing brackets 3, 3E; 3 ', 3'E can be attached to each frame before the frame as well as the frame after the frame as described above. In this case, needless to say, it is not necessary to provide a notch in the locking edge of the horizontal frame.

Subsequently, a method of fixing the window frame 2 having a plurality of fixing brackets 3, 3E; 3 ', 3'E attached to each frame to the window opening frame 1 using the fixing brackets will be described mainly with reference to FIG. The description will be given with reference.
First, the window frame 2 is fitted into the window opening frame 1, and the fixing portion 35 of the second metal fitting 3B of each fixing metal is fixed to the outdoor side surface of the window opening frame 1, that is, the fixing metal 3E of the vertical frames 23, 24. 3, the pillars 13, 14, the fixing brackets 3 ′, 3 ′ E of the upper frame 11, the lintel 11, and the fixing brackets 3 ′, 3 ′ E of the lower frame 2, respectively. In a state where the window frame is in contact with the window frame, the window frame is moved in the horizontal direction and the vertical direction to position the window frame with respect to the window opening frame. In this case, the positioning may not be precise. Then, in the state of non-precision positioning, the wood screw 5 (corresponding to the first screw) is inserted into the window opening frame 1 (column, lintel, window stand) from the long hole 37 of the fixing portion 35 of the second metal fitting 3B of each fixing metal fitting. Then, the second metal fittings 3B are temporarily fixed to the window opening frame 1.

  Next, the window frame 2 is slightly moved in the left and right and up and down directions, and horizontal and vertical level adjustments are performed so that the lower frame 22 is completely horizontal and the vertical frames 23 and 24 are completely vertical. In this case, the wood screw 5 of each fixing bracket is slidable in the major axis direction and the direction perpendicular thereto with respect to the long hole 37 of the second bracket 3B, and in the fixing brackets of the upper and lower horizontal frames 21, 22. Since the long axis 37 of the fixing part 35 of the second metal fitting is vertical, the position of the window frame can be adjusted. At that time, the fixing part 35 of the second metal fitting is within the range of the long hole 37. It moves relative to the wood screw 5. After the positioning of the window frame in the horizontal direction and the vertical direction is optimized by this level adjustment, the wood screw at the fixing portion of each fixing bracket is completely tightened.

  Next, a wedge-shaped spacer 61 is inserted between the upper surface of the window base 12 and the lower frame 22 to fix the height of the lower frame 22 relative to the window base 12.

  Subsequently, the indoor / outdoor direction position of the window frame is adjusted by applying a force in the indoor / outdoor direction to at least the four corners of the window frame 2, that is, in the vicinity of the connection portion between the vertical frame and the horizontal frame. At that time, the screw 4 of each fixing bracket can slide in the major axis direction and the direction perpendicular to the long hole 38 of the second coupling portion 36 of the second bracket 3B. The position can be adjusted to any position in the indoor / outdoor direction within the range of 36 long holes 38. During this adjustment, the vertical frame grooves 23c and 24c of the first metal fitting 3A separated from the second metal fitting 3B in each of the fixing metal fittings until the first coupling portion 33 abuts on the second coupling portion 36 of the second metal fitting. Or after moving along the grooves 21c and 22c of the horizontal frame, the gap opened to the outdoor side between the locking edges 21a, 22a, 23a and 24a on the outdoor side of each frame and the inner peripheral surface of the opening frame Then, a bit of a screwdriver (driver) is inserted, the screw 4 is completely tightened, the first metal fitting 3A and the second metal fitting 3B are joined together, and each frame 21 to 24 is fixed to the window opening frame 1.

  Thereafter, spacers 62, 63, 64 similar to the lower spacer 61 in the region including the wood screw penetration position between the vertical frames 23, 24 and the pillars 13, 14 and between the upper frame 21 and the lintel 11 are included. To fix the position of each frame. In this case, the spacers 61 to 64 do not perform the position adjusting function and the fixing function as in the conventional product, but simply function to fix the window frame whose mounting position is adjusted by the fixing bracket.

  Finally, wood screws 7 corresponding to the third screws are passed through the spacers 61 to 64 from a predetermined position corresponding to the spacers 61 to 64 on the inner side of the inner peripheral surface of the base wall of each frame 21 to 24. Then, it is screwed to the window opening frame 1 to completely fix the window frame 2 to the window opening frame 1.

  In FIGS. 1, 2 and 7, reference numeral 8 denotes the lintel 11, the window base 12, and the pillars 13, 14 so as to cover the fixing part 35 of the second bracket of each fixing bracket on the outdoor side surface after the window frame is fixed. It is a waterproof sheet pasted from the outdoor side surface to the outer surface of the base wall of each frame, and 9a and 9b are frames having a width extending from the outdoor side end surface of each frame to the building exterior material 10. Yes, it can be easily installed by elastic fitting of a pair of locking edges on the back, and it has the function of improving the decorativeness of the window frame and improving the waterproofness by accommodating the exterior parting. ing.

  In order to slidably provide the first metal fitting 3A of the fixing metal on the outer part of each frame of the window frame, a groove is formed by the above-mentioned pair of locking edges, and the locking portions at both ends are inserted into this. Not only the structure to be locked but also any shape that can be slidably held in each frame in the longitudinal direction of each frame. The inclination angle of the first coupling portion and the second coupling portion of the fixing bracket is most preferably 45 degrees in order to minimize the amount of movement for adjustment. Any angle is acceptable. In addition, if a long hole is provided in the coupling portion into which the screw is inserted first and the hole into which the screw is screwed last is a perfect circle, the overlapping positional relationship between the coupling portion of the first metal fitting and the coupling portion of the second metal fitting is There is no particular restriction. Moreover, it is not restrict | limited in particular whether the shape of the 1st metal fitting and the 2nd metal fitting and the mounting form with respect to each frame are symmetrical.

  The present invention is applied to a case where a window frame formed by assembling a mold material is fitted to a window opening frame and fixed to a predetermined position on the outdoor side surface of the window opening frame regardless of whether it is made of metal or resin. Is possible.

  Moreover, although the window frame 2 in which the sliding doors d1 and d2 and the screen door d3 are built is shown in the drawings, the present invention is similarly applied to the window frame that holds the fitting glass without fittings. Applicable.
