Description

  The present invention is a double window forming tool for adding a second window plate to an existing window plate to form a double window.

  Conventionally, there is a construction in which an additional window plate is added to an existing window plate to form a double window from the viewpoint of heat insulation, ultraviolet ray prevention and sound insulation. As an example, a spacer member having a predetermined thickness is attached to the peripheral portion of an existing window plate with a double-sided tape or an instantaneous adhesive, and a second window plate is further pasted on the spacer member with a double-sided tape or the like. The construction method is known. The double-sided tape or the like is used because it is difficult to temporarily fix the spacer member or the second window plate to be added to the existing window plate standing upright, and it must be fixed in a short time.

  Such construction requires skill not only when the window is small, but when the window is of a size that generally requires a double window. This is because the work of sticking the double-sided tape linearly and without the tilting of the second window plate is an extremely difficult work that cannot be undone.

  Moreover, since the double-sided tape affixed on the existing window board can be seen, there also exists a fault that it is unpreferable on an external appearance.

  In view of this, there has been considered a structure in which the second window plate is fixed onto the spacer by pressing the second window plate from the outer surface using a z-shaped clip (see Patent Document 1).

  However, in such a structure, the second window plate is pressed on the spacer, and in this state, one end of the clip is elastically deformed and the clip is inserted between the window frame and the existing window plate. In this state, it is necessary to sandwich the second window plate between the spacer and the clip while being bent into the window frame.

  These operations can never be said to be easy, and there is a risk that the window frame, the existing window pane, the second window pane, etc. may be damaged due to excessive force in the work process. Even if it is possible, it is doubtful.

  Furthermore, the spacer must be attached to the existing window plate with a double-sided tape or the like, and the problems regarding workability and appearance due to this have not been solved. In terms of appearance, the exposure of the clip is also a big problem.

JP 2011-252328 A

  The present invention has been made to solve the above-mentioned problems all at once, and its main purpose is to make it possible to additionally attach a second window plate to an existing window plate very easily and with good appearance. It is intended.

  That is, the double window forming tool according to the present invention is for adding a second window plate to an existing window plate supported around the window frame to form a double window. It has the following requirements. (1) A spacer member disposed between the existing window plate and the second window plate. The spacer member is formed with a mounting surface on which the outer peripheral edge of the back surface of the second window plate is mounted. (2) The first insertion portion formed at one end is inserted between the window frame and the existing window plate, and the second insertion portion formed at the other end is provided in the spacer member.

A sandwiching member that is sandwiched and held.

If it is such, in the state which the installer pressed the 2nd window plate with respect to the mounting surface of the spacer member attached along the inner periphery of a window frame, a clamping member is made into a 2nd window. Since the double window can be formed simply by engaging with the spacer member from the thickness direction of the plate, it can be constructed very easily without difficulty.
Moreover, since a double-sided tape and an adhesive agent are unnecessary, it can be redone during the construction, which is advantageous in appearance.

  In order to further improve the appearance, the spacer member or the sandwiching member substantially covers a protruding portion that protrudes from the window frame side of the insertion member to the window plate side when viewed from the plane direction of the window plate. Is preferred.

  As a specific configuration, the insertion member includes a connection plate that is erected with respect to the existing window plate so as to be sandwiched between the outer surface of the spacer member and the inner peripheral edge of the window frame, and the connection The first insertion portion extends from one end of the plate on the existing window plate side toward the window frame, and the second insertion portion extends from the other end of the connection plate toward the spacer member. Can be mentioned.

  If it is such, even if it looks at the formed double window from front and back, since an insertion member is hardly visible except the end surface of the connection board, it does not impair the appearance.

  An engagement structure for engaging the spacer member and the sandwiching member in order to sandwich the second window plate between the spacer member and the sandwiching member while attaching the sandwiching member to the spacer member from the thickness direction. Is provided on one of the spacer member and the sandwiching member, and is formed on the window frame side of the second window plate so as to be perpendicular to the second window plate, the spacer member, and the sandwiching member. It is preferable to have an engaging convex part which is provided on the other side of the insertion member and fits with the engaging concave part.

  If the spacer member and the sandwiching member are mounted so as to circulate along the inner peripheral edge of the window frame, the spacer member and the insertion member look like a window frame, so that the appearance is uncomfortable. There is no airtightness. Along with this, heat insulation and sound insulation can be improved.

  If the spacer member and the sandwiching member have a straight long shape and an equal cross-sectional shape, they can be cut into windows of any size by cutting according to the length of each side of the window frame. Correspondingly, a double window can be formed.

  As described above, according to the present invention, it is possible to add and attach the second window plate to the existing window plate very easily and with good appearance.

An insertion member 42 for mounting along the inner peripheral edge of the first and second spacers 41, and a sandwiching member 43 for sandwiching and holding the second window plate 3 between the spacer member 41 by engaging with the spacer member 41. .

  Below, each member is demonstrated with reference to FIGS.

  The spacer member 41 is made of some elastically deformable resin such as vinyl chloride, for example, and includes a bottom surface 411 that contacts the existing window plate 2 and a mounting surface 412 on which the outer peripheral edge of the back surface of the second window plate 3 is mounted. And a straight long shape having an equal cross-sectional shape.

  A rising surface 416 is formed from one end of the mounting surface 412, and the rising movement of the second window plate 3 mounted on the mounting surface 412 is restricted by the rising surface 416.

  The spacer member 41 is disposed around the inner peripheral edge of the window frame 1 between the existing window plate 2 and the second window plate 3, and between the existing window plate 2 and the second window plate 3. A space S1 having an effect of heat insulation and sound insulation is formed.

  The insertion member 42 is formed by bending a single flat plate made of a metal such as stainless steel, for example. The connection plate 423, a first insertion portion 421 extending vertically from one end of the connection plate 423, and the connection plate The second insertion portion 422 extends vertically from the other end of 423 in the opposite direction to the first insertion portion 421.

  The first insertion portion 421 is inserted between the window frame 1 and the existing window plate 2 along the surface of the existing window plate 2, whereby the insertion member 42 is inserted into the window frame 1. It is attached. In this attached state, the first insertion part 421 is buried in the window frame 1, and only the connecting plate 423 and the second insertion part 422 are exposed.

  In the present embodiment, at least one insertion member 42 is attached to each side of the window frame 1.

  The second insertion portion 422 is inserted into the insertion recess 413 having a groove shape extending along the longitudinal direction of the outer surface of the spacer member 41, whereby the spacer member 41 is interposed via the insertion member 42. It is attached to the window frame 1.

  The insertion recess 413 has a shape in which the opening width is smaller than the thickness of the second insertion portion 422 and the width increases as going deeper.

  Therefore, when the second insertion portion 422 is inserted, the spacer member 41 is elastically deformed so that the opening width of the insertion recess 413 is widened, and the second insertion portion 422 is sandwiched from the thickness direction.

  In addition, the depth dimension of the insertion recess 413 is equal to or greater than the length dimension of the second insertion part 422, and the second insertion part 422 is inserted into the insertion recess 413 so as to be almost completely within the spacer member 41. Buried in.

  The connecting plate 423 is configured so that the first insertion portion 421 is inserted between the window frame 1 and the existing window plate 2 and the second insertion portion 422 is inserted into the insertion recess 413. It is placed upright with respect to the existing window plate 2 so as to be sandwiched between the side surface and the inner peripheral edge of the window frame 1.

  The sandwiching member 43 is of a linear long shape having an equal cross-sectional shape, and is formed of a resin such as vinyl chloride.

  The sandwiching member 43 is provided with a contact surface 431 that contacts the outer peripheral edge of the surface of the second window plate 3, and the contact surface 431 and the spacer member 41 are engaged by engaging the spacer member 41 from the thickness direction. The second window plate 3 is sandwiched between and fixed to the mounting surface 412.

  The engaging mechanism for engaging the sandwiching member 43 with the spacer member 41 extends along the longitudinal direction of the sandwiching member 43, the groove-like engaging recess 414 extending along the longitudinal direction of the spacer member 41, It consists of a protrusion-like engaging projection 432 that engages with the engaging recess 414.

  More specifically, on each outer surface of the engaging convex portion 432, as shown in FIG. 4 in particular, a locking protrusion 433 having a semicircular cross section extends along the longitudinal direction. A locking groove 415 that engages with the locking protrusion 433 is provided on the inner surface so as to extend along the longitudinal direction.

  With the engagement mechanism, the spacer member 41 and the sandwiching member 43 are engaged, and the top surface of the sandwiching member 43 protrudes from the window frame 1 in the planar direction when the second window plate 3 is sandwiched. It is formed so that there is no.

  A second placement surface 412 ′ is formed on the opposite side across the engagement concave portion 414, and a second contact surface 431 ′ is also formed on the outer side of the engagement convex portion 432.

  Further, a space cut out in a substantially rectangular cross section is formed below the placement surface 412.

  Next, an example of a procedure for forming the double window 100 using the double window forming tool 4 according to this embodiment will be described below with reference to FIGS.

  First, the lengths of the prepared standard members of the spacer member 41 and the sandwiching member 43 having several kinds of lengths and the window frame 1 are compared. Cut to the length corresponding to the length of.

  Next, the first insertion portion 421 of the insertion member 42 is inserted between the window frame 1 and the existing window plate 2, and one or more insertion members 42 are attached to the upper, lower, left, and right sides of the window frame 1.

  Subsequently, the second insertion portions 422 of the plurality of insertion members 42 attached to the window frame 1 are sandwiched by the insertion recesses 413 of the spacer member 41, and the spacer member 41 is attached to the insertion member 42.

  The spacer member 41 attached in this way is arranged around the inner periphery of the window frame 1, and the mounting surface 412 of the spacer member 41 also forms a frame shape inside the window frame 1.

  Therefore, the second window plate 3 having an outer periphery smaller than the outer periphery of the mounting surface 412 having a frame shape is mounted on the mounting surface 412.

  In this state, a gap S <b> 2 (see FIG. 3) is formed outside the side peripheral surface of the second window plate 3.

  Finally, in a state where the second window plate 3 is pressed against the mounting surface 412, the engagement convex portion 432 of the sandwiching member 43 is sandwiched and engaged with the engagement concave portion 414 of the spacer member 41, and the first The double window 100 is formed by sandwiching and holding the two window plates 3 between the mounting surface 412 and the contact surface 431 in the thickness direction.

According to the double window forming tool 4 according to the present embodiment configured as described above, the installer performs the second operation on the mounting surface 412 of the spacer member 41 attached along the inner peripheral edge of the window frame 1. Since the double window 100 can be formed only by engaging the sandwiching member 43 with the spacer member 41 from the thickness direction of the second window plate 3 in a state where the window plate 3 is pressed, the construction is easy.
In addition, since a double-sided tape or an adhesive is not required, it is possible to redo during construction, which is advantageous in appearance.

  In a state where the second window plate 3 is placed on the placement surface 412, the spacer member 41 is restricted from moving inward by the second window plate 3 and extends toward the spacer member 41. Since the movement in the plane direction is restricted by the insertion portion 422, the second window plate 3 does not come off as long as it is placed on the placement surface 412.

  In addition, in a state where the sandwiching member 43 is engaged with the spacer member 41, the second window plate 3 is sandwiched between the mounting surface 412 of the spacer member 41 and the contact surface 431 of the sandwiching member 43 from the thickness direction. As long as the insert member 43 does not come off, the second window plate 3 will not come off.

  That is, the spacer member 41 is firmly attached as the construction progresses, and in the state where the double window 100 is formed, the spacer member 41 does not come off unless the sandwiching member 43 is removed.

  In addition, when the clamping member 43 is attached, the engaging convex portion 432 and the engaging concave portion 414 are fitted, and the engaging protrusion 433 and the engaging groove 415 are engaged, so that the attaching member 43 is attached to the spacer member 41. The sandwiching member 43 is not easily detached.

  Further, when the spacer member 41 is attached, the length of the connecting plate 423 is formed to be substantially equal to the distance from the insertion recess 413 to the bottom surface 411 of the spacer member 41, so that the spacer member 41 is connected to the insertion member 42. It is attached without play between the window plate 2.

  As described above, in the construction for forming the double window 100, each member can be firmly attached.

  Regarding the ease of construction, the opening width of the insertion recess 413 is smaller than the thickness of the second insertion portion 422, and the width increases toward the back. Even if the spacer member 41 is attached, it does not fall off easily, and the installer can release the spacer member 41 and start the next construction after attaching the spacer member 41.

  Moreover, since the insertion recessed part 413 is formed along the longitudinal direction, the 2nd insertion part 422 of the insertion member 42 attached to the arbitrary positions of the longitudinal direction with respect to the window frame 1 is made into the insertion recessed part 413. Can be easily sandwiched.

  Regarding the appearance of the formed double window 100, since the connecting plate 423 is erected with respect to the existing window plate 2, the insertion member 42 can be seen from both the front and back directions. Since it is almost invisible except for the end face of the connecting plate 423, the appearance is not impaired.

  Further, since the outer periphery of the second window plate 3 is smaller than the outer periphery of the mounting surface 412, a gap S2 is formed outside the side peripheral surface of the second window plate 3, and the second window plate 3 is heated by the temperature change. Even if it expands, it does not curve and the appearance of the second window plate 3 is not impaired by the deformation.

  Furthermore, since the spacer member 41 and the sandwiching member 43 are arranged around the inner peripheral edge of the window frame 1, these members look like a window frame and do not cause an uncomfortable appearance. In addition, the airtightness of the space S1 can be improved, and the heat insulation and sound insulation can be improved.

  Regarding the existing single window to which the second window plate 3 is additionally attached, the upper surface of the sandwiching member 43 in a state in which the spacer member 41 and the sandwiching member 43 are engaged and the second window plate 3 is sandwiched. However, since it is formed so as not to protrude from the window frame 1 in the plane direction, even if the existing single window is a sliding window, the double window 100 is formed without inhibiting the opening and closing of the window. be able to.

  Further, since the mounting surface 412 is formed outside the engaging concave portion 414 and the contact surface 431 is formed outside the engaging convex portion 432, even when the existing window plate 2 is large, FIG. As shown in FIG. 2, by arranging the spacer member 41 in the center of the existing window plate 2, two additional second window plates 3 are attached to the existing window plate 2 to form the double window 100. Can do.

  Regarding the manufacture of the members, since the spacer member 41 is formed with a space cut out in a substantially rectangular cross section, the weight of the member can be reduced and the material cost can be reduced.

  The present invention is not limited to the above embodiment.

  For example, although the mounting surface 412 is formed outside and inside the engaging recess 414, it may be formed only inside the engaging mechanism as shown in FIG.

  The insertion member 42 has a shape in which a single plate is bent twice. However, as shown in FIG. 7, the single plate is bent once and the first insertion portion 421 and the second insertion are inserted. The part 422 may be formed vertically.

  Moreover, in this embodiment, although the several insertion member 42 is attached to each edge | side of the window frame 1, it is made to attach the insertion member 42 which comprises one linear elongate shape to each edge | side of the window frame 1. Also good.

The spacer member 41 and the sandwiching member 43 are provided around the inner peripheral edge of the window frame 1, but may be provided intermittently on the inner peripheral edge of the window frame 1.
By providing in this way, the airtightness of the space S1 is inferior, but the material can be reduced.

  The engagement mechanism for engaging the spacer member 41 and the sandwiching member 43 has an engagement recess 414 provided in the spacer member 41 and an engagement projection 432 provided in the sandwiching member 43. However, as shown in FIG. 8, the engaging protrusion 414 provided in the spacer member 41 and the engaging recess 432 provided in the sandwiching member 43 may be provided.

  The sandwiching member 43 does not need to be integrated as in the present embodiment, and may be configured to fix the member having the contact surface 431 to the spacer member 41 with a screw or the like.

  In the present embodiment, the insertion concave portion 413 is a concave groove formed in the longitudinal direction, but a plurality of holes into which the first insertion portion 421 is inserted are provided intermittently in the longitudinal direction. Also good.

  In the construction procedure of this embodiment, the insertion member 42 is inserted between the window frame 1 and the existing window plate 2 and the spacer member 41 is attached to the insertion member 42.
