Description

  The present invention relates to a security mechanism for a sash window in which a pressing edge for fixing a panel such as a glass plate or a plastic plate to a window frame or a shoji is mounted on the outdoor side of the panel.

For example, Patent Document 1 discloses a sash window in which a pressing edge for fixing a panel to a window frame or a shoji frame is mounted on the outdoor side of the panel.
FIG. 7 is a cross-sectional view showing the main part of the sash window described in this document. As shown in FIG. 7, a fitting killing portion 16 a to which the panel g 1 is fixed is provided on the right side with a vertical 15 ′ provided between the left and right vertical frames 13 ′ and 14 ′ of the window frame 1 ′ as a boundary. The window g1 on the left side is provided with an opening / closing part 16b to which a glass shoddle 17 is vertically opened and closed so as to be freely opened and closed. , The vertical frame 14 'and the vertical frame 15') fixed to the convex walls 121 ', 141', 151 'integrally formed, and the outdoor side is fitted into the groove formed in the outdoor side portion of the window frame It is fixed by 6a '. Further, the panel g2 of the shoji 17 is fixed on the indoor side by a convex wall 172 formed integrally with the shoji ridge 171 and fixed on the outdoor side by a pressing edge 6b 'fitted on the coffin.
Japanese Patent Laid-Open No. 2002-138756 FIG. 1 and FIG.

  However, as shown in the partial enlarged view of FIG. 7, the pressing edge used in the above-described conventional sash window has a pair of locking edges 62 and 63 formed on one end side of the hollow portion 61 as opposed to the window frame. Is fitted in a dovetail groove (173 in FIG. 7) formed so as to be opposed to the members to be opened (vertical frame and vertical, upper frame and lower frame; upper and lower and left and right ridges of the shoji). The locking edge 63 is attached by engaging with the locking edge formed at the mouth edge of the groove 173.

  Therefore, as shown by the arrow in the partially enlarged view of FIG. 7, when the outdoor side portion of the pressing edge 6b ′ is strongly pressed in the indoor direction indicated by the arrow A1 with a screwdriver or other tools, the pressing edge 6b ′ is deformed. By sequentially moving the pressing place to another position of the pressing edge, the distance between the pair of locking edges 62 and 63 is reduced, and when the pressing edge 6b 'is moved away from the groove 173 indicated by the arrow A2, the pressing edge 6b 'is pulled out and the panel g2 becomes removable. The panel g1 of the fitting killing part can be removed in the same manner. Therefore, it cannot be said that the conventional sash window in which the pressing edge is mounted on the outdoor side is sufficient in crime prevention.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a sash window in which unauthorized removal of the pressing edge is impossible.

To solve the above problems, the present invention provides a sash window ledges for securing the panel to the window frame or sash stile is mounted outdoors side of the panel, an indoor-side and outdoor side of the front Symbol ledge at one end at a position spaced in a pair of locking edges to be engaged is provided fitted into a groove formed in the window frame and / or sash, ya on the outside of the locking edge, to form the groove outdoor deformation preventing edge that contacts the outside surface of the side wall is found integrally formed, inclined to the front end portion of the front Symbol deformation preventing edge, the outdoor side of the outdoor side walls forming the groove to be thinner toward the tip The taper which forms is formed (Claim 1).

It is desirable that the deformation preventing edge of the pressing edge applied when the sash window is a fitting window is in contact with the inner peripheral surface of the window frame, the lower frame and / or the vertical frame (claims) Item 2 ).

According to the invention of claim 1, the pushing edge is provided on the outdoor side of the locking edge on the outdoor side, in addition to the pair of locking edges fitted and locked in the groove of the window frame or the shoji. Since it has a deformation preventing edge that contacts the outdoor surface of the outdoor side wall that forms the groove, bending in the indoor direction is prevented even if the pressing edge is pressed from the outdoor side. Accordingly, since the pair of locking edges cannot be removed from the groove, it is impossible to remove the pressing edge itself. Therefore, the removal of the panel can be surely prevented, so that the crime prevention property becomes very high. In addition, since the taper which inclines toward the outdoor surface side of the outdoor side wall which forms the groove so as to become thinner toward the tip is formed at the tip of the deformation prevention edge, the tip of a tool such as a screwdriver is attached to the tip of the deformation prevention edge. And the outdoor side wall that forms the groove of the window frame or shoji ridge becomes difficult to insert. Accordingly, the crime prevention property is further improved.

According to the invention of claim 2 , the tip of the deformation prevention edge of the fitting window is in contact with the inner peripheral surface of the upper, lower frame and / or vertical frame. It becomes more difficult to insert between the upper frame, the lower frame and / or the vertical frame.

Next, embodiments of the present invention will be described with reference to the drawings.
1 and 2 are drawings of an example in which the present invention is applied to a fitting window, FIG. 1 is a longitudinal sectional view, FIG. 2 is a transverse sectional view, and FIG. 3 is an enlarged view of an ellipse C1 portion of FIG. FIG.

  1 and 2 show an example in which the present invention is applied to a heat-insulating sash fitting window in which a window frame is connected to a metal frame 1 arranged on the outdoor side and a resin frame 2 arranged on the indoor side. Is. The metal frame 1 is formed by connecting the upper frame 11, the lower frame 12, and the left and right vertical frames 13 and 14 in a square shape by a well-known technique, and the mounting edges 111, 121, 131, and 141 of each frame are The building body forming the window opening 3 is fixedly attached to the outdoor side surface of the outer wall 4 with a wood screw or a nail 5a.

In addition, the resin frame 2 has an upper frame 21, a lower frame 22, and left and right vertical frames 23 and 24 joined in a square shape by a well-known technique, and the outer peripheral surface of each frame is fitted into the window opening 3. In combination, they are in contact with the inner peripheral surface of the window opening, and wood screws 5b are screwed into the building body from the holes formed in the inner peripheral surface of each frame.
The metal frame 1 and the resin frame 2 have an outer peripheral surface of the resin frame on the inner peripheral surface of the connecting edges 112, 122, 132.142 extending in the indoor direction from the metal frame in the upper frame and the left and right vertical frames. And are connected by screwing in a screw 5c from the outer peripheral side.

  Each of the frames 21, 22, 23, 24 of the resin frame 2 is integrally formed with convex walls 211, 221, 231, 241 projecting in the center direction of the window opening 3 at the outdoor side end portions. An elastic member b1 for supporting the panel g1 from the indoor side is fitted into the grooves 212, 222, 232, and 242 provided on the outdoor surface. Reinforcing edges 113, 123, 133, and 143 extending along the outdoor side surfaces of the convex walls 211, 221, 231, and 241 of the resin frame 2 are formed on the indoor side portion of the metal frame 1. The front end is fitted to locking edges 213, 223, 233, and 243 formed integrally with a member on the outer peripheral side of the window frame forming the grooves 212, 222, 232, and 242, and the screw 5 c on the outer peripheral side and the inner peripheral side The metal frame 1 and the resin frame 2 are firmly coupled to each other with the locking edges 213, 223, 233, and 243.

  In addition, the panels (the illustrated example is a multi-layer glass) from the reinforcing edges 113, 123, 133, 143 on the inner peripheral surface of each frame of the metal frame 1 (upper frame 11, lower frame 12, vertical frames 13, 14) to the outdoor direction. ) Dovetail grooves 114, 124, 134, and 144 are formed at positions separated by a distance corresponding to the thickness of g1, and these dovetail grooves are continuous in a square shape. Each dovetail groove is configured such that the pressing edges 6A and 6B can be fitted thereto.

  The pushing edge 6A in FIG. 1 is fitted into the dovetail grooves 114 and 124 of the upper frame 11 and the lower frame 12 of the metal frame, and has a hollow portion 61 at one end portion to provide a required strength. A pair of locking edges that extend substantially in parallel from a position separated from the indoor / outdoor direction on one side of the part and have a taper and a claw at the tip and are fitted into the grooves 114 and 124 on the inner peripheral surface of the metal frame 62, 63. Further, a groove 64 is formed on the indoor side surface of each pressing edge, and an elastic member b2 for supporting the panel g1 from the outdoor side is fitted into the groove 64.

The pressing edge 6B of FIG. 2 is fitted into the dovetail grooves 134 and 144 of the left and right vertical frames 13 and 14, and has almost the same shape and structure as the pressing edge 6A, but the difference is the ellipse C1 of FIG. Referring to FIG. 3 which is an enlarged view of the portion , the deformation preventing edge that abuts the outdoor surface of the outdoor side wall 134 a constituting the groove 134 on the locking edge 62 on the outdoor side of the pair of locking edges 62, 63. 65 is provided integrally, and a taper that is inclined toward the outdoor surface side of the outdoor side wall 134a is formed at the front end portion of the deformation preventing edge so as to become thinner toward the front end .

Ledges 6A, 6B includes a convex wall 211, 221, 231, 241 and the reinforcing edges 113,123,133,143 of the metal frame 1 of the resin frame 2, there from the reinforcing edge of the inner peripheral surface of the metal frame groove 114, After fitting a panel (in the illustrated example, a reversible glass) g1 to a glass fitting portion formed in a portion between 124, 134, and 144 by a well-known method, each groove 114, 124, 134, and 144 is fitted. And the panel g1 is fixed. In a state where the pressing edges 6A and 6B are fitted, the panel g1 is held by the indoor side elastic member b1 and the outdoor side surface by the outdoor side elastic member b2.

  As described above, the pressing edges 6B fitted to the left and right vertical frames 13, 14 are provided with the deformation preventing edges 65, so that a pair of locking edges 62 of the pressing edges 6B are provided as shown in FIG. , 63 is pushed into the groove 134 of the metal frame, and the claw at the ends of the locking edges 62, 63 is engaged with the opening edge of the groove 134 by the elastic restoring force of the locking edge, so that Is fitted so that it cannot be removed, and has an anti-deformation edge 65 that abuts against the outdoor surface of the outdoor side wall 134 a that forms the groove 134. Accordingly, the fitting portion of the pressing edge 6B with respect to the vertical frame 13 has a three-layered structure in which the locking edge 62 on the outdoor side of the pressing edge 6B, the outdoor side wall 134a of the dovetail groove 134, and the deformation preventing edge 65 are male and female fitted. . Therefore, since the fitting portion has a large bending resistance, even if the outdoor side surface of the pressing edge 6B is strongly pressed in the indoor direction, the locking edge 62 and the deformation preventing edge 65 on the outdoor side of the pressing edge are prevented from being bent. Is done. The pressing edge 6B on the side of the vertical frame 14 has a similar bending prevention effect. Accordingly, since neither of the right and left pushing edges 6B can be removed from the window frame, the panel g1 cannot be removed from the window frame. That is, the crime prevention property of the window is improved.

An outdoor side wall that constitutes a dovetail groove for fitting a pressing edge to the outdoor side of the fitting killing portion projects from the inner peripheral surface of the outdoor side portion of the metal frame toward the center of the window opening. Therefore, the tip of the deformation preventing edge that is in contact with the outdoor surface of the outdoor side wall is close to the inner peripheral surface of the outdoor side portion of the metal frame.
In the case of its, the space between the inner circumferential surface of the tip and the metal frame of the deformation preventing edge are separated even slightly, by inserting a tool into the gap, the deformation preventing edge there is a risk that the bent outdoors direction. Further, when the tip of the deformation prevention edge 65 is cut at right angles to the extending direction of the deformation prevention edge, the tip of the tool such as a flathead screwdriver is hooked on the tip of the deformation prevention edge 65 so that the deformation prevention edge 65 is There is a risk of bending in the outdoor direction. After successful folding, the outdoor side surface of the press rim is pushed indoors as in the conventional manner to narrow the distance between the pair of inner and outer locking edges, and the press ledge can be pulled out from the groove and removed. . Therefore, in order to completely prevent such bending of the deformation prevention edge in the outdoor direction, as shown in FIG. 3, a taper 65 'is formed so that the tip of the deformation prevention edge 65 becomes thinner toward the tip. Is good. By doing so, it becomes impossible or very difficult to hook and fold the tool on the tip of the deformation preventing edge 65, so that the crime prevention property is improved. Furthermore, it is preferable that the tip of the deformation preventing edge is brought into contact with the inner peripheral surface of the metal frame. Thereby, since insertion of a tool can be prevented , crime prevention property improves further.

  In the above embodiment, the deformation preventing edge 65 is provided only on the pressing edge 6B fitted to the left and right vertical frames 13, 14, but the vertical frames 13, 14 are not provided with the deformation preventing edge 65, and the upper, lower A similar deformation preventing edge may be provided on the pressing edge 6A fitted to the frames 11 and 12. Further, the deformation preventing edge 65 may be provided on the vertical and horizontal pressing edges attached to the vertical frame and the upper and lower frames. In this case, since all the pressing edges that are continuous in a rectangular shape are not easily removed, the crime prevention property is further improved.

  4 and 5 are drawings when the present invention is applied to an opening / closing window. FIG. 4 is a longitudinal sectional view, FIG. 5 is a transverse sectional view, and FIG. 6 is an enlarged view of an ellipse C2 portion of FIG. The same members as those in FIGS. 1 and 2 are denoted by the same reference numerals. The illustrated opening / closing window is an example in which the glass shoddle 7 is attached to the metal frame 1 so as to be opened and closed in a vertical sliding manner, but the opening / closing type of the glass shoddy is arbitrary.

  The metal frame 1 and the resin frame 2 are the same as those shown in FIGS. The glass shoji 7 is a convex wall 721, which is formed by joining a rectangular metal cage 71 on the outdoor side and a rectangular resin cage 72 on the indoor side by a known technique, and projects from the inner peripheral side of the resin cage. An elastic member b1 protruding in the outdoor direction is fitted in a groove formed on the outdoor side surface of 722, 723, 724. Further, grooves 711, 721, 731, 741 are formed on the inner peripheral side of the outdoor side portion of the metal rod 71, and the convex walls 721, 722, 723, 724 and the groove 711 are formed on the upper, lower, left and right metal rods. Between 721,731,741, the glass fitting part for fitting the panel g2 which consists of a laminated glass is formed so that it may continue in a rectangular shape.

  And after fitting panel g2 by the well-known method to the glass fitting part, the same or similar pressing edge 6B 'as the pressing edge 6B in the previous embodiment is fitted in each dovetail groove 711,721,731,741. Has been.

  The pushing edge 6B ′ will be described with reference to FIG. 6. A pair of locking edges 62, 63 extending from the hollow portion 61 to the same side, and a groove 64 opening in the indoor direction from the indoor side surface of the hollow portion 61, An elastic member b2 protruding in the indoor direction is fitted in the groove. The pressing edge 6B ′ is formed by fitting the pair of locking edges 62, 63 into the dovetail grooves 711, 721, 731, 741 of the metal rod 71, so that the tapered pawls at the tips of the locking edges 62, 63 are respectively It engages with the opening edge of the dovetail so as not to be easily removed. When the pressing edge 6B 'is fitted, the panel g2 is held by the indoor elastic member b1 and the outdoor elastic member b2.

  Further, a deformation preventing edge 65 is also formed on the locking edge 62 on the outdoor side of the pressing edge 6B '. The deformation preventing edge 65 contacts the outdoor surface of the outdoor side wall 731a forming the dovetail groove 731 when the pressing edge 6B 'is fitted. Therefore, the fitting portion of the pressing edge 6B ′ with respect to the metal rod is triple in which the engaging edge 62 on the outdoor side of the pressing edge 6B ′, the outdoor side wall 731a of the dovetail groove 731 and the deformation preventing edge 65 are fitted to male and female. Even if the outdoor side portion of the pressing edge 6B ′ fitted to the metal rod is strongly pressed in the indoor direction as in the case where the pressing edge 6B with the deformation preventing edge 65 is fitted to the metal frame 1, The bending of 62 is effectively prevented. Therefore, even in the opening / closing window in which the pressing edge is mounted on the outdoor side, it is effectively prevented that the pressing edge is unjustly removed and the panel g2 is removed.

In the embodiment shown in FIGS. 4 and 5, the outdoor side surface of the shoji screen is smooth. Therefore, when the tip of the deformation prevention edge 65 is cut at a right angle to the extending direction of the deformation prevention edge, the tip of the tool such as a flathead screwdriver is hooked on the tip of the deformation prevention edge 65 so that the deformation prevention edge 65 is attached. There is a risk of bending in the outdoor direction. As a countermeasure, as shown in FIG. 6, a taper 65 ′ that is inclined toward the outdoor surface 731 a side of the outdoor side wall that forms the groove 731 so as to become thinner toward the distal end is formed at the distal end portion of the deformation preventing edge 65. It is formed . Thus, since bending the tip of the deformation prevention rim 65 by hooking a tool becomes impossible or very difficult, crime prevention is on improvement.

  The present invention is not limited to a window that is a fitting part as in the previous embodiment, a window that is an opening and closing part as in the following example, and a fitting part and opening and closing as shown in FIG. It is not necessary to say that it can be applied to a window having a part. Moreover, it cannot be overemphasized that the material of the member which comprises a window is applicable also in any case of a metal or resin.
