  However, in the case of the compound type squeezed window described in Patent Document 1, a lock mechanism such as an operation handle and a sub-lock is attached to the sliding face of the shoji, so that the siding width of the heel increases and the glass opening width decreases. It was. Therefore, the heat insulation performance cannot be exhibited in the glass, and it is difficult to increase the heat insulation of the joinery. In addition, since the cold air enters from the metal part of the bag through the lock mechanism such as the handle unit and the sub-block, there is a problem that the indoor side of the bag is condensed.

  The present invention has been made in view of such a problem, and does not cause a gap between the opening frame and the shoji, and further suppresses a decrease in the surface temperature of the opening frame so as to prevent dew-proofing. An object of the present invention is to provide a lock structure for a composite joinery which is improved.

The lock structure of the composite joinery according to the present invention is formed on the outdoor side with an opening frame body provided with a metal frame formed on the outdoor side and a resin frame formed on the indoor side, which can be opened and closed in the opening frame body. It is equipped with a metal cage and a shoji with a resin cage formed on the indoor side, and has a hidden cage structure in which the indoor side of the resin cage is covered with the resin frame of the opening frame, and is locked to the prospective surface of the resin cage An operating part of the mechanism is provided separately from the handle for opening and closing the shoji, a main body part is provided in the inside of the resin bowl , and the resin bowl having the main body part of the lock mechanism is provided on the indoor side of the resin bowl. An air layer comprising a space partitioned by a first packing and a second packing is provided between the resin frame and the resin frame.

According to the lock structure of the composite joinery according to the present invention, since the operation unit of the lock mechanism is installed on the prospective surface of the resin bottle of the shoji in the hidden fence structure, the opening frame body including the resin frame is processed when the lock mechanism is installed. Therefore, it is difficult to form a gap with the shoji, and it is possible to suppress a decrease in the surface temperature of the resin frame portion, and it is difficult for condensation to occur in the operation portion of the resin frame and the lock mechanism. In addition, even if dew condensation occurs in the operation part of the lock mechanism provided on the resin bowl of the shoji, the dew condensation water hardly flows into the indoor side, and corrosion of the interior material provided on the resin frame can be prevented. In the closed state in which the shoji is stored in the opening frame, the first packing and the second packing are arranged between the surface of the shoji resin cage and the resin frame of the opening frame to form an air layer. The heat transfer between the indoor side and the indoor side can be reduced by the air layer, so that the heat insulation can be improved, and condensation is hardly generated on the indoor side resin frame.

  In addition, the first packing may be disposed in contact with the resin rod of the shoji around the four sides of the resin frame in a state in which the shoji is closed, and the second packing may be disposed on the inner side in the finding direction than the first packing.

  According to the lock mechanism of the composite joinery according to the present invention, it has a hidden fence structure in which the indoor side of the resin fence is covered with the resin frame of the opening frame, and the operation part of the lock mechanism is provided on the prospective surface of the resin fence. Even if dew condensation occurs in the operation part of the lock mechanism provided in the resin bottle, the dew condensation water does not easily flow into the indoor side, and corrosion of the interior material can be prevented. In addition, since the lock mechanism is not provided on the resin frame of the opening frame, it is possible to suppress a decrease in the surface temperature of the resin frame portion, and it is difficult for condensation to occur.

It is a principal part longitudinal cross-sectional view of the vertical extension window by embodiment of this invention. It is a principal part horizontal sectional view of the vertical penetration window shown in FIG. FIG. 3 is an enlarged cross-sectional view of a lock mechanism for the vertical window shown in FIG. 2. It is an enlarged view of the lock mechanism provided in the prospective surface of the resin vertical shaft shown in FIG. It is a side view of the locking mechanism which cut | disconnected the prospective surface of the resin vertical hook shown in FIG. 4 in the AA cross section.

Hereinafter, a vertical window as an example of a composite joinery according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.
1 and FIG. 2, the vertical window 1 rotates a shoji 3 housed in a frame 2 attached to a building opening formed in the building frame around the vertical shaft on the suspension side. It can be opened to the outside. The vertical extending window 1 is a composite type made of a metal such as an aluminum alloy and a resin, and includes a rectangular frame-shaped composite frame 2 and a composite type shoji 3 that can be opened and closed in the frame 2. is set up.

  The frame body 2 forms an opening frame body composed of a rectangular frame-shaped metal frame 4 made of an aluminum alloy or the like provided on the outdoor side and a synthetic resin resin frame 5 provided on the indoor side. Yes. The metal frame 4 is formed of left and right metal vertical frames 6 and 7, a metal upper frame 8, and a metal lower frame 9. In the metal upper frame 8, the outer metal upper frame portion 8a and the inner metal upper frame portion 8b are connected via a resin bridge member 10 to reduce heat transfer indoors and outdoors. In the metal lower frame 9, the outer metal lower frame portion 9a and the inner metal lower frame portion 9b are connected via a resin bridge member 15 to similarly reduce heat transfer indoors and outdoors.

  The resin frame 5 includes left and right resin vertical frames 11 and 12 formed on the indoor side of the left and right metal vertical frames 6 and 7, a resin upper frame 13 formed on the indoor side of the metal upper frame 8, and a metal lower frame 9. It is comprised with the resin lower frame 14 formed inside.

  In addition, it may replace with the metal vertical frame 7 and the resin vertical frame 12, and it is good also as the continuous window which provided the stand. Further, the left and right resin vertical frames 11 and 12, and the resin upper frame 13 and the resin lower frame 14 respectively form a lattice-like portion 40 having a plurality of air chambers 39 in the vertical and horizontal directions in a cross-sectional view. The chamber 39 reduces heat transfer between the outdoor side and the indoor side.

  Moreover, the shoji 3 is comprised by the metal cage | basket 16 which consists of metals, such as an aluminum alloy provided in the outdoor side, and the resin-made resin cage | baskets 17 provided in the indoor side. The metal rod 16 is formed of left and right metal vertical rods 18 and 19, a metal upper rod 20 and a metal lower rod 21. The resin rod 17 includes left and right resin vertical rods 23 and 24 formed on the indoor side of the left and right metal vertical rods 18 and 19, a resin upper rod 25 formed on the indoor side of the metal upper rod 20, and the metal lower rod 21. It is comprised with the resin lower collar 26 formed inside. A glass body 31 made of, for example, double-layer glass is fitted inside the metal cage 16 and the resin cage 17 that are framed in a quadrilateral shape of the shoji 3.

The shoji 3 of the vertical window 1 is placed in a closed state by contacting the left and right resin vertical frames 11, 12, the resin upper frame 13, and the resin lower frame 14 of the frame body 2. It is only openable.

In addition, in the vertical frame portion on the door stop side of the frame body 2 shown in FIG. 3, a fitting concave portion 30 is formed on the outdoor side end surface 11 a of the resin vertical frame 11 of the frame body 2. One end of one packing 32A is fitted and the other end protrudes to the outdoor side. The first packing 32 </ b> A has, for example, a substantially U shape, and a tip end portion of the first packing 32 </ b> A is in contact with the indoor side end face 23 a of the resin vertical wall 23. Further, a second packing 33A is formed so as to protrude at a position spaced apart from the first packing 32A on the outdoor side end face 11a of the resin vertical frame 11, and in the example shown in the figure, the second packing 33A is bent in a substantially J-shaped cross section. Or it has a curved shape.
The first and second packings 32A and 33A may be made of a soft material such as PVC (polyvinyl chloride), and the second packing 33A may be integrally formed with the resin vertical frame 11, and in this case, the second packing 33A. These parts are extruded with a softer resin than the resin vertical frame 11.

  In the closed state in which the shoji 3 is housed in the frame 2, the front end of the first packing 32A is in contact with the indoor side end face 23a of the resin vertical shaft 23 in the shoji 3, and the front end of the second packing 33A is the end face. 26a (see FIG. 3) or slightly spaced. In this case, the first packing 32 is strongly pressed against the end surface 23a of the resin vertical rod 23, and the second packing 33A is relatively lightly abutted against the end surface 23a of the resin vertical rod 23 or set so as to be separated at a minute interval. To form a heat insulating space.

  Thus, an air layer 35A forming a heat insulating space is formed by the resin vertical frame 11, the resin vertical rod 23, and the first and second packings 32A and 33A of the frame body 2 in a horizontal sectional view. Since this air layer 35A is formed of resin and packing, heat insulation is high, and heat transfer between the outdoor side and the indoor side can be reduced by insulating between the frame 2 and the shoji 3. It is possible to improve heat insulation and dew proofing. Moreover, since the resin vertical rod 23 of the shoji 3 is in contact with the first and second packings 32A and 33A in a state where the shoji 3 is closed to the frame body 2, airtightness can be secured and the opening / closing operation of the shoji 3 is affected. Don't give.

Further, the heat-insulating air layer 35A is formed not only between the resin vertical frame 11 and the resin vertical wall 23 but also between the resin vertical frame 12 and the resin vertical wall 24 on the suspension side as shown in FIG. Has been. In this case, the 1st packing 32B is formed in the outdoor side end surface 12a of the resin vertical frame 12, and the 2nd packing 33B is formed in the other end side at intervals. Therefore, each end surface 12a, 24a of the resin vertical frame 12 and the resin vertical rod 24 and the first and second packings 32B, 33B form an air layer 35B of a heat insulating space.
Similarly, an air layer 35C partitioned by a packing 33C and ribs 32C is formed on the outdoor side end face 13a of the resin upper frame 13 shown in FIG. Moreover, the 1st packing 32D is attached to the outdoor side end surface 14a of the resin lower frame 14, and the 2nd packing 33D is formed in the lower side at intervals. And the air layer 35D of heat insulation space is formed by each end surface 14a, 26a of the resin lower frame 14, the resin lower collar 26, and 1st and 2nd packing 32D, 33D.

The first packing 32B, 32D, the second packing 33B, 33D, and the air layers 35B, 35D of the heat insulating space have the same configuration as the first packing 32A, the second packing 33A, and the air layer 35A described above. 35C may have the same configuration.
Therefore, the air layers 35 </ b> A to 35 </ b> D of the heat insulating space are formed in a frame shape that forms each side of the quadrangle between the quadrangular frame-shaped resin frame 5 of the frame 2 and the quadrangular frame-shaped resin cage 17 of the shoji 3. .

  In the drawing, each of the first packings 32A, 32B, and 32D is formed in a substantially U-shaped cross section, and the second packings 33A, 33B, and 33D are formed in a substantially cross-sectional shape or a J-shape. However, the first and second packings can adopt any shape. In the closed state of the shoji 3 with respect to the frame 2, the first packing 32A, 32B, 32D strongly abuts on the resin cage 17, and the second packing 33A, 33B, 33D is weakly abutted on the resin cage 17 or spaced apart at a small interval. It only has to be. As described above, the first packing 32A, 32B, 32D, the second packing 33A, 33B, 33D, and the packing 33C are made of a synthetic resin such as PVC softer than the resin frame 5 and the resin rod 17, or an elastic member such as rubber. .

  Next, in the vertical frame portion on the door-to-door side of the frame 2 shown in FIG. 3, the resin vertical rod 23 provided on the indoor side of the metal vertical rod 18 of the shoji 3 is located on the indoor side of the glass body 31 and is a metal It is formed in a substantially quadrangular frame shape in cross section connected to the vertical rod 18. A glemon handle 38 is attached to the center portion in the vertical direction on the prospective surface 23b which is the side surface of the end surface 23a which is the indoor-side finding surface of the resin downpipe 23. Further, for example, a sub-lock is attached as a lock mechanism 41 under the glemon handle 38 on the prospective surface 23b, and the operation unit 44 is exposed indoors. In addition, not only the said position but the attachment position of the lock mechanism 41 can be installed in the arbitrary positions of the prospective surface 23b.

The lock mechanism 41 has a main body portion 42 and a lock pin 43 that are mounted inside the resin vertical rod 23. The main body 42 and the lock pin 43 of the lock mechanism 41 are built in at a position closer to the glass body 31 than the end surface 23a of the resin vertical rod 23, and are not exposed to the end surface 23a. As shown in FIGS. 4 and 5, when the lock mechanism 41 is moved up and down, the operation lever 46 is interlocked to rotate the lock pin 43 around the shaft 48 to move the lock pin 43 around the metal vertical frame. 6 is configured to switch between locking and unlocking by advancing and retracting to a recess (not shown) provided in 6 to engage or disengage.
Therefore, when the operation portion 44 of the lock mechanism 41 is operated in the vertical direction, the lock pin 43 rotates around the shaft 48 and engages or disengages from the recess provided in the metal vertical frame 6 to switch between locking and unlocking. Then, the shoji 3 is fixed to the frame 2 in the locked state. In addition, in the example shown in FIG. 4, “open” or “closed” can be displayed in conjunction with switching between locking and unlocking by moving the lock mechanism 41 up and down.

  Moreover, as shown in FIG. 1, the resin upper collar 25 and the resin lower collar 26 of the shoji 3 have a structure hidden behind the resin upper frame 13 and the resin lower frame 14 of the frame 2 on the indoor side. Similarly, as shown in FIG. 2, the resin vertical fence 23 on the door-end side of the shoji 3 and the resin vertical fence 24 on the hanging-end side are suspended from the resin vertical frame 11 on the door-end side of the frame 2 on the indoor side. It has a structure hidden behind the resin vertical frame 12 on the original side. Accordingly, the vertical window 1 according to the present embodiment constitutes a hidden fence in which the upper and lower left and right edges of the shoji 3 are hidden indoors by the frame 2. For this reason, the frame 2 can reduce the movement of heat inside and outside the vertical, left, and right folds of the shoji 3.

  The vertical window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. 1 and 2, in the vertical extension window 1 according to the present embodiment, as shown in FIGS. 4 and 5, in the closed state in which the shoji 3 is placed in the frame body 2, The operation part 44 of the lock mechanism 41 provided on the prospective surface 23b is operated to move the lock pin 43 up and down to lock the shoji 3 to the frame 2 at the locking position.

  In this state, between the resin vertical rod 23 of the shoji 3 and the resin vertical frame 11 of the frame 2, the first and second packings are provided between the end surface 23 a of the resin vertical rod 23 and the end surface 11 a of the resin vertical frame 11. Thermal insulation between the outdoor side and the indoor side is reduced by being insulated by the air layer 35A and the other air layers 35B to 35D partitioned by 32A and 33A. Furthermore, heat transfer is also suppressed by the plurality of air chambers 39 provided in the resin vertical frames 11 and 12, the resin upper frame 13, and the resin lower frame 14 of the frame 2 that covers the resin cage 17 of the shoji 3.

  Moreover, in the resin downspout 23 provided with the lock mechanism 41, since the cold air on the outdoor side is transmitted through the metal downspout 18, dew condensation occurs on the prospective surface 23b exposed to the indoor side and the operation unit 44 of the lock mechanism 41. However, the heat transfer to the indoor side is suppressed by the air layer 35A between the resin vertical wall 23 and the resin vertical frame 11, and condensation is formed on the indoor side exposed surface of the resin vertical frame 11. Hard to occur. Therefore, even if dew condensation occurs in the lock mechanism 41, the dew condensation water is unlikely to flow indoors from the prospective surface 23b, and corrosion of the interior material provided on the resin vertical frame 11 can be prevented.

As described above, according to the vertical extending window 1 with the hidden eaves structure according to the present embodiment, since the lock mechanism 41 is installed on the prospective surface 23b of the resin eaves 23 on the door stop side of the shoji 3, the resin eaves 23 The end surface 23 a and the resin vertical frame 11 are not processed for mounting the lock mechanism 41. Therefore, there is no defect in the watertight / airtight line on the door-to-door surface between the shoji 3 and the frame 2. In addition, since the air layer 35A having high heat insulation is provided between the resin vertical rod 23 of the shoji 3 and the resin vertical frame 11 of the frame body 2, heat transfer between the resin vertical rod 23 and the resin vertical frame 11 is reduced. It is possible to prevent dew condensation by suppressing a decrease in the surface temperature of the resin vertical frame 11.
In addition, heat from the outdoor side may be transmitted to the resin vertical shaft 23 of the shoji 3 to cause condensation on the lock mechanism 41 and the prospective surface 23b. Even in this case, the condensed water remains on the prospective surface 23b, and the indoor side Corrosion of interior materials can be prevented because it is difficult to flow into

Note that the lock structure of the composite joinery according to the present invention is not limited to the vertical extending window 1 according to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention.
For example, in the above-described embodiment, the lock mechanism 41 is provided on the resin vertical rod 23 of the shoji 3, but it may be provided on the resin upper rod 25 or the resin lower rod 26 instead.

In the above-described embodiment, the sub-lock is provided as the lock mechanism 41, but the present invention is not limited to such a configuration, and an appropriate lock mechanism such as a cam latch handle can be adopted.
Moreover, although the composite joinery provided with the metal and the resin according to the present invention is used for the vertical extension window 1 as an embodiment, it is not limited to this, and the horizontal extension window, the sliding window, the sliding door, etc. Needless to say, the lock structure of the present invention can be employed in a composite joinery having a cover structure such as various windows and doors.
