Description

  The present invention relates to a reforming sash that allows a new sash to be attached while the existing sash is attached when the existing sash is replaced with a new sash.

  When replacing an existing sash with a new sash, it is conceivable to remove the existing sash from the window opening and replace it with a new sash. However, removing the existing sash is troublesome because it takes time and money. Therefore, a modified sash is known in which a new sash is attached while the existing sash is attached to the window opening (see Patent Documents 1, 2, and 3).

  This is because when the existing sash is an internal sash, for the lower frame, a mounting member is fixed to the outside of the upper room, a fall prevention member is fixed to the indoor side, and a new sash is attached to the mounting member and the fall prevention member. It is configured to be fixed. In this case, the lower frame of the new sash is supported on the mounting member, and the mounting piece of the new sash is screwed to the vertical surface on the outdoor side of the mounting member. The mounting piece is also called a nail fin and is provided so as to be flush with the sash around the sash regardless of whether it is old or new, and is configured to be fixed to the window opening with a wood screw. .

In addition to these, several refurbishment methods have been proposed and implemented.
JP 2003-82941 A JP 2003-82942 A JP 2004-124436 A

However, the sash refurbishment methods that have been performed so far have the following problems.
(1) It is necessary to separately attach the attachment member and the fall prevention member on the lower frame of the existing sash, and it takes time and labor to position and screw each of them.
(2) Since the mounting member is provided on the outer rail support portion of the lower frame of the existing sash to support and fix the new sash, the load of the new sash is biased toward the outdoor side of the window base and is not easily stabilized.
(3) The mounting member is arranged so as to straddle the outer rail of the existing sash and is not supported by the outer rail. Since the outer rail of the sash is directly subjected to the load of the shoji, it is a part that is firmly designed for strength, but it is not reasonable because it is not used.
(4) Dedicated sashes were used for the new sashes, and some were not applicable to general sashes.

The ends of the vertical frame body 23a on the outdoor side and the indoor side have a T-shaped cross section.
When framed, the nailing fins 24a, 24b, 24c are flush with the outer periphery of the new sash B.

  The resin blocks 37a, 37b, and 37c made of synthetic resin are fixed to the indoor sides of the upper and lower frames 21 and 22 and the vertical frame 23. These mounting operations are the mounting operations of the upper and lower frames 21 and 22 and the vertical frame 23. After the end. First, the vertical blocks 37c may be attached to both sides, and the upper and lower blocks 37a and 37b may be inserted between them and fastened with screws from the angle member 27 side.

[Base material]
Next, the new sash B is mounted on the existing sash A through the base frame C. The base frame C is rectangularly framed from an upper base material 40, a lower base material 41, and a vertical base material 42, each made of an extruded mold material of aluminum, and flat portions 44 and 45 are formed with a central mounting wall 43 interposed therebetween. Thus, the mounting wall 43 is formed parallel to the surface direction of the window opening 1, and the flat portions 44 and 45 are formed perpendicular to the surface direction of the window opening 1. The flat portion 45 on the outdoor side extends from the outer end of the mounting wall 43 (the end near the peripheral surface of the window opening 1) to the outdoor side. The flat portion 44 on the indoor side extends from the inner end of the mounting wall 43 (the end portion on the side far from the peripheral surface of the window opening 1) to the indoor side. In addition, the flat portion 45 on the outdoor side of the lower base member 41 is further composed of a horizontal portion 45a on the indoor side and a gentle slope portion 45b formed slightly obliquely on the outdoor side. The contact piece 46 is formed to hang in parallel with the mounting wall 43. The mounting wall 43, the bottom portion 44a of the indoor flat portion 44, and the horizontal portion 45a of the outdoor flat portion 45 are formed thicker than other portions. Further, the tip of the abutting piece 46 is bent toward the indoor side to form a locking piece 47. Further, the flat portion 44 on the indoor side is formed hollow, and a groove 49 that opens inward along the longitudinal direction is formed in the outdoor side hollow portion 48 of the upper base material 40 and the lower base material 41. . In addition, the length from the contact piece 46 of the outdoor side edge part of the lower base material 41 to the mounting wall 43 is the outer rail between the outer rail 14 and the inner rail 13 from the screen door rail 12 of the lower frame 3 of the existing sash A. The length is up to a position close to 14 (may be on the outer rail 14).

  The width dimensions of the upper base material 40, the lower base material 41, and the vertical base material 42 are all set to be the same, and the dimensions from the outdoor side end to the mounting wall 43 and from the mounting wall 43 to the indoor side end. The dimensions are also set to the same length.

  The width dimension of the lower base member 41 is set so as to cover the entire existing sash A.

  Moreover, since the horizontal part 45a of the lower base material 42, the mounting wall 43, and the bottom part 44a of the indoor side flat part 44 are mounted on the existing sash A and support the new sash B, the strength capable of withstanding the load is provided. It is formed thick so as to have.

[Reform sash construction method]
Next, when attaching the new sash B to the existing sash A, first, the base frame C is disposed along the inner peripheral surface of the existing sash A. At that time, as shown in FIGS. 1 to 5, when the lower base member 41 is mounted on the lower frame 3, the horizontal flat portion 45 on the outdoor side is placed on and supported by the outer rail 14. The horizontal flat portion 44 on the indoor side is placed on and supported by the inner rail 13 and the rising piece 15. Then, the abutment piece 46 at the end on the outdoor side is brought into contact with the screen door rail 12 for positioning. At this time, the mounting wall 43 of the lower base member 41 is positioned closer to the outer rail 14 between the outer rail 14 and the inner rail 13 of the lower frame 3 of the existing sash A. After positioning, the indoor flat portion 44 is integrally screwed to the window base 10 together with the existing sash A with a long screw 50. At this time, the screw 50 is preferably inserted through a work hole (not shown) on the upper surface of the flat portion 44 and screwed until the head reaches the bottom of the hollow portion 48.

  Next, the upper base member 40 is positioned by engaging the contact piece 46 at the end on the outdoor side with the screen door guide piece 7 of the upper frame 2 of the existing sash A, and like the lower base member 41, The long screw 50 from the flat part 44 on the indoor side is integrally screwed to the lintel 11 together with the existing sash A.

  Further, the vertical base member 42 may be positioned by aligning the end portion on the outdoor side with the end surface on the outdoor side of the vertical frame 4 of the existing sash A, but as shown in FIG. The positioning base plate 42 is fixed to the upper end and the lower end of the vertical base member 42 so as to protrude upward and downward, and this is engaged with the groove 49 of the lower base member 41 and the upper base member 40. Reference numeral 70 denotes a positioning notch for the engagement plate 51. Thereby, the vertical base material 42 is stably positioned at a predetermined position easily and reliably. Then, it fixes to a predetermined position by screwing together with the existing sash A to the pillar with a long screw 50 from the flat part 44 on the indoor side. The engaging plate 51 may be fixed and positioned only at one of the upper end and the lower end of the vertical base member 42.

  With the above configuration, the upper base member 40, the lower base member 41, and the vertical base member 42 are disposed along the inner peripheral surface of the existing sash A with reference to the screen door rail 12 of the lower frame 3 of the existing sash A. C is assembled, and the mounting wall 43 is flush.

  Next, when the new sash B is attached to the base frame C, the new sash B is first framed in a rectangular shape and fitted into the base frame C of the window opening 1, and the lower frame 22 of the new sash B is attached to the lower base material 41. On the flat portion 44 on the indoor side. Then, nail-fitting fins 24 a, 24 b, 24 c in the middle part between the upper and lower frames 21, 22 and the vertical frame 23 of the new sash B are brought into contact with the mounting wall 43 and fixed with screws 52. Further, as shown in FIG. 5, the lower frame 22 has an indoor side end mounting piece 34 fixed to the flat portion 44 of the lower base member 41 with screws, and the upper frame 21 and the vertical frame 23 are interposed with an adjustment material 53. The upper base member 40 and the vertical base member 42 are screwed. As a result, the new sash B is fixed to the base frame C.

  Furthermore, a long resin block 37b made of synthetic resin is fixed to the indoor side of the newly installed sash B. The upper and lower resin blocks 37a and 37b are fixed to the angle members 27 and 35 of the upper and lower frames 21 and 22 by screws, and the same applies to the vertical resin block 37c. Accordingly, the resin blocks 37a, 37b, and 37c are disposed so as to be flush with the indoor side end surfaces of the base members 40, 41, and 42.

  According to the above-described configuration, when constructing the new sash B, the base frame C is attached to the existing sash A, and the new sash B is fitted and disposed in the base frame C, and the nailing fins 24a, 24b, and 24c are attached. Since it is only necessary to fix the screw to the wall 43, it does not take time and construction is easy.

  In addition, a nailing fin is generally provided on the outer peripheral surface of the sash, but since a mounting wall 43 is provided on the base frame C corresponding to this, the base frame C is not a dedicated sash but a general sash. Even if it is a sash, it can be attached and the attachment becomes a familiar work and can be performed easily and quickly.

[Internal appearance cosmetic treatment]
Next, in the above-mentioned stage, the base frame C and the existing sash A can be seen on the indoor side and the outdoor side. Therefore, the outer periphery on the outdoor side of the new sash B has vertical and vertical makeup to improve the appearance and appearance. The cover material 54, 55, and 56 are concealed, and the indoor side is concealed by vertical and vertical indoor frames 57, 58, and 59.

  The decorative cover materials 54, 55, and 56 are each formed of a substantially plate-like aluminum extrusion mold material, and a pair of fitting pieces 60 are formed on one side in the width direction. The decorative cover materials 54, 55, and 56 are attached to the vertical and vertical base materials 40, 41, and 42 via an attachment attachment 61. The attachment 61 is made of an aluminum extruded mold having a C-shaped cross section, and a protrusion 62 is formed on the tip portion so as to face each other. The attachment 61 is fixed with screws to the outdoor side ends of both ends of each base material. Therefore, as shown in FIGS. 7 and 8, a total of eight are attached to the four corners. The four decorative cover members 54, 55, and 56 are fixed by fitting the fitting pieces 60 inside the protrusions 62 at the tips of the corresponding attachment attachments 61, respectively. A vertical decorative cover material 56 is attached between the cover material 55 and the cover material 55. Both ends of the vertical decorative cover material 56 are swallowed by the upper and lower decorative cover materials 54 and 55.

  With the above configuration, the portions between the newly installed sash B and the base frame C and between the base frame C and the existing sash A are covered with the decorative cover materials 54, 55, and 56, and are hidden from the outdoor side.

  Next, the indoor side of the new sash B is covered with indoor frame frames 57, 58 and 59. The indoor frame frames 57, 58, 59 are made of synthetic resin, and are each composed of a basic frame material 63 and an auxiliary frame material 64. As shown in FIG. The leg part 66 of the book protrudes, the fitting groove 67 is formed in the indoor side of the frame material main body 65, and the cap 69 is provided in the fitting groove 67 so that attachment or detachment is possible. The auxiliary frame member 64 has a shape in which a fitting piece 68 that can be fitted in the fitting groove 67 is formed in a portion corresponding to the leg portion 66 of the basic frame material 63.

  The basic frame material 63 is in contact with the base material and the indoor side end surface of the resin block 37 a and is fixed to the window base 10, the lintel 11, and the pillar 9 with screws by a long screw 50 inserted through the fitting groove 67. . When the height is insufficient, as shown in the upper and side indoor frame frames 57 and 59 in the figure, the auxiliary frame material 64 is further superposed on the basic frame material 63 to form the fitting piece 68 into the basic frame. What is necessary is just to fit and fix to the fitting groove 67 of the material 63. FIG. The indoor frame frames 57, 58, 59 are integrally disposed with the resin blocks 37a, 37b, 37c.

  The indoor frames 57, 58, and 59 may each be composed of only the basic frame material 63. However, as shown in FIGS. 1 and 2, the indoor frame frames 57, 58, and 59 are connected to the basic frame material 63. When the auxiliary frame material 64 (one or a plurality) is used, the auxiliary frame material 64 may be pre-stacked on the basic frame material 63 and assembled vertically.

  With the above configuration, the portions between the new sash B and the base frame C and between the base frame C and the existing sash A are covered by the indoor frame frames 57, 58, and 59 and are hidden from the indoor side. After that, if the inner shoji a, the outer shoji b and the screen door c are placed in the new sash B, the construction is completed.

[Function and effect]
As described above, when constructing the new sash B, only the lower base material 41 needs to be attached on the lower frame 3 of the existing sash A, and the lower frame 22 of the new sash B is installed on the indoor side of the lower base material 41. The nailing fin 24b that is placed on the flat portion 44 and formed at the center of the lower frame 22 of the new sash B may be fixed to the mounting wall 43 with screws. Thus, in order to attach the newly installed sash B, only the lower base material 41 needs to be attached to the lower frame 3 of the existing sash A, so that it does not take time and construction is easy.

  Further, the lower frame 22 of the newly installed sash B is placed on the flat portion 44 on the indoor side of the lower base material 41. However, in the natural state, the semi-external sash is closer to the outdoor side of the window opening 1. It is easy to receive force so that the upper part falls to the outdoor side. Therefore, the load tends to concentrate on the outdoor side end of the indoor flat portion, that is, the mounting wall 43. Since the mounting wall 43 is located on the indoor side of the outer rail 14 of the lower frame 3 of the existing sash A, the load of the new sash B is also received on the center side of the window base 10, so that the entire sash can be stably supported. .

  Moreover, since the mounting wall 43 is located on or near the outer rail 14 where the strength is ensured most because of the load of the shoji, the support of the new sash B becomes more stable.

  Further, as the mounting wall 43 is positioned on the indoor side of the outer rail 14 of the lower frame 3 of the existing sash A, the nail driving fin 24b is less likely to be affected by rainwater due to the approach to the indoor side.

  The width dimension of the lower base member 41 is set so as to cover the entire existing sash A, and from the lower end of the mounting wall 43 of the new sash B to the outdoor side, the horizontal portion 45a of the lower base member 41 and the gentle slope. Since the part 45b is formed continuously and these parts have a draining function, it is not necessary to attach a draining material to the new sash B.

  In addition, the lower frame that is the basis of the sash is generally provided with a portion to be placed on the window sill and a nailing fin that is fixed to the side surface on the outdoor side of the window sill. 41 includes a flat portion 44 corresponding to the window base 10 and a mounting wall 43 corresponding to screwing of the nailing fins 24b. Therefore, the lower base member 41 is attached to a general sash instead of a dedicated sash. In addition, the installation is a familiar task and can be performed easily and quickly.

  Further, the lower base member 41 that is most heavily loaded in the new sash B has a structure that is supported by the outer rail 14 of the existing sash A. In general, the parts that require the most strength in the sash are the outer rail and the inner rail that support the shoji. Therefore, the structure in which the lower base member 41 is supported on the outer rail is very reasonable in terms of strength.

  Similarly, the internal sash and the external sash basically have the same spacing and height difference between the outer rail and the inner rail, and the configuration in which the rising piece is on the indoor side is the same. Since the lower base member 41 is supported by the outer rail 14 and the inner rail 13 or the rising piece 15, the existing sash A can be handled by either an internal sash or an external sash.

  Further, since the outdoor side end of the lower base material 41 is positioned by contacting the screen door rail of the existing sash A, the correct position of the lower base material 41 can be obtained easily and reliably.

  In addition, since the flat portion of the lower base material 41 is integrally screwed to the window base 10 together with the existing sash A, the connection between the lower base material 41 and the existing sash A can be strengthened.

  Further, since the flat portion 44 of the lower base material 41 is formed in a hollow shape and the head portion of the screw is located in the hollow portion, the screw head is not exposed to the outside, and the lower base material 41 When the flat part is screwed together with the existing sash A to the window base 10, the screw can be deeply tightened into the window base 10.

  Further, since the groove 49 is formed in the upper surface portion of the flat portion 44 of the lower base material 41, it can be used as a drainage groove and can also be used for positioning the vertical base material 42.

  In addition, a synthetic resin resin block 37b is provided on the indoor side of the lower frame 22, and a synthetic resin indoor frame 58 is provided on the indoor side of the lower base member 41, so that the resin block 37b and the indoor frame are provided. 58 are integrally disposed, even if the existing sash A, the base material 41, and the new sash B are all made of metal, a sash having a high heat insulating property as a whole can be obtained by applying the reform sash. The same applies to the upper frame 21 and the upper base material 40 and the vertical frame 23 and the vertical base material 42. Therefore, if the shoji is a heat insulating shoji, the whole can be made into a heat insulating window.

  As for heat insulation, as shown in FIGS. 1, 2, 5, etc., the resin blocks 37a, 37b, 37c and the indoor picture frames 57, 58, 59 of the synthetic resin member having high heat insulation are as follows. However, the upper base material 40, the lower base material 41, the vertical base material 42, and the indoor frame frames 57, 58, 59 with high heat insulation properties are not in contact with each other. So that they are spaced slightly apart from each other. Thereby, the heat insulation between a base frame and a frame is ensured favorably, and a frame does not dew condensation. Therefore, the resin blocks 37a, 37b, and 37c protrude slightly inward from the upper base member 40, the lower base member 41, and the vertical base member 42. When the indoor picture frames 57, 58, 59 are composed of the basic picture frame material 63 and the auxiliary picture frame material 64, one of the reasons for assembling the two picture frame materials after pre-stacking them is to automatically This is because a gap is formed between the base frame and the frame.

[Others]
Next, a case where the existing sash A is a semi-external sash will be described for the lower frame portion. Since the upper frame and the vertical frame may be configured according to the lower frame as in the above example, the description is omitted. The same reference numerals as those in the above figure indicate the same members.

  In FIG. 9, the existing sash A is a high window type semi-external sash, and the basic configuration is the same as the above-mentioned internal sash, except that the position of the nailing fins is mainly on the indoor side and the lower frame The screen door rail 12 is different in that it is lower.

  The new sash B is the same as the semi-external sash described above.

  Further, the upper and lower and side base materials and the base frame C constituted by these base materials are the same as those described above. However, a piece member 71 is attached to the contact piece 46 and the locking piece 47 formed at the outdoor side end of the lower base member 41.

  The mounting procedure for forming the base frame C on the existing sash A and fitting the new sash B inside thereof and fixing it with screws or the like is the same as described above.

  Since the screen door rail 12 of the existing semi-external sash is lower than that of the internal sash, the contact piece 46 of the lower base material 41 cannot be brought into direct contact with the screen door 12. What is necessary is just to make it contact | abut to the screen door rail 12 through the piece member 71 for positioning.

  In this way, the positioning can be achieved by engaging the contact piece 46 on the outdoor side end portion of the lower base material 41 and the screen door rail 12 of the lower frame of the existing sash A via the positioning piece member 71. Since the member 71 can be attached and detached, it is attached at the time of shipment from the factory, and can be removed and used when unnecessary.

  As described above, according to the reform sash configuration, it is possible to cope with whether the existing sash A is an internal sash or a semi-external sash.

  FIG. 10 shows an example in which a sash B with a surface lattice is attached as a newly-installed sash. The sash B with a surface lattice projects a frame for attaching the surface lattice 77 to the outdoor side, and an arm 72 protrudes from there. Since the base materials 41, 42 and the like on the side and the side do not interfere with the outdoor side of the new sash B, even if the new sash B protrudes to the outdoor side, there is no hindrance to the mounting. Therefore, according to the above reform sash configuration, it can be applied to a sash with a surface lattice.

  Further, FIG. 11 shows an example in which a fitting sash B is attached as a newly installed sash, and can be attached with the same configuration and the same procedure. In addition, about the attachment aspect of a sliding sash, all may be handled similarly.

  Also, as shown in FIG. 12, the inner rail 13 and the rising piece 15 are formed on the indoor side of the lower frame of the existing sash A, and the flat portion 44 on the indoor side of the lower base member 41 is placed thereon. However, there is a design in which the inner rail 13 is not much different from the height of the outer rail 14, and in this case, the inner rail 13 and the rising piece 15 have different heights. The indoor side may be placed on the high rising piece 15.

  Furthermore, as shown in FIG. 13, when the height of the rising piece 15 on the indoor side is particularly high, the lower base member 41 can be placed on the outer rail 14 via the height adjusting member 73. Good.

  Next, the windows are roughly divided into the above-described high window type and sweep window type, but these are not greatly different in basic configuration. However, in the sweep-out window, since the lower frame is continuously arranged with the floor surface and people enter and exit, the lower interior frame may be stepped on, and a load sufficient to withstand it is necessary. Therefore, as shown in FIG. 14, a sweep-out indoor picture frame 58 composed of a dedicated aluminum core 74 and a resin cover 75 is attached between the floor surface 76 and the height of the resin angle 35 of the lower frame 22 of the new sash B. It is. According to this, since the indoor frame 58 is reinforced by the core member 74, sufficient strength is ensured.
