Even if condensed water that flows into the space partitioned by or flows down on the wall of the lower ledge can be prevented from flowing into the indoor side through the second engagement part, it drains to the outside through the hole provided at the bottom. it can.

In addition, the space formed by the lower ledge and the lower collar is partitioned into an external pressure space communicating with the hole and an internal pressure space having an indoor pressure, and an airtight piece that seals both ends of the external pressure space at both ends of the lower ledge It is preferable to install.
Since the lower pressing edge is sealed by installing airtight pieces at both ends in the longitudinal direction, the fitting groove of the panel into which the outside air flows and the interior can be sealed with the airtight pieces. In addition, the airtight piece can ensure airtightness between the external pressure space in the lower pressing edge and the internal pressure on the indoor side, and can prevent outside air, rainwater, and the like in the lower pressing edge from flowing into the indoor side.
In addition, since the airtight piece hermetically seals both sides of the external pressure space formed by the lower pressing edge and the lower collar, the hermetic piece is pushed when attaching one end and the other end of the lower pressing edge sequentially when assembling the lower pressing edge. Because it is elastically deformed, it is possible to secure a lot of money.

Moreover, the airtight piece may be made of an elastic body.
By providing the elastic body as an airtight piece that seals both ends of the external pressure space formed at both ends of the lower pressing edge, airtightness can be reliably ensured.

  According to the joinery according to the present invention, even if rainwater or condensed water that soaks into the panel fitting groove flows into the external pressure space formed by the lower ledge and the lower collar, the hole portion communicates with the external pressure space. In addition, it is possible to prevent rainwater and dew condensation water and external pressure from being drawn into the indoor side through the second engaging portion, and rainwater and dew condensation water can be discharged through the hole.

4 is a partially enlarged view of FIG. 2 showing the lower frame 4 of the vertical window 1 and the lower frame 11 of the shoji 9. In FIG. 4, the lower pressing edge 25 is integrally formed by engaging a metal pressing piece 25a and a resin pressing piece 25b at engaging portions a and b. The upright piece 25aa on the outdoor side of the metal pressing piece 25a is pressed at the upper end by the packing 22 on the indoor side and engaged with the resin pressing piece 25b, and the lower end is engaged with the metal lower bar 18 at the engaging part c. doing. Further, the indoor metal pushing piece 25a and the metal lower bar 18 are engaged with each other by the engaging portion d.
In the engaging portion c, the arc-shaped hook portion 25ab at the lower end portion of the upright piece portion 25aa is engaged with the claw portion 18b of the metal lower bar 18 to constitute a metal touch. Metal touch can circulate rainwater.

Further, a space is formed by partitioning a space between a lower surface of the metal pressing piece 25a having the arc-shaped hook portion 25ab and a substantially U-shaped lower piece portion 18c which is a partitioning surface of the metal lower collar 18, and is formed on the bottom surface of the lower piece portion 18c. A drain hole 36 is formed as a hole communicating with the lower frame 4. Therefore, this space constitutes an external pressure space 37 into which outside air flows through the gap between the lower rod 11 and the lower frame 4. In this external pressure space 37, the engaging portions c constituting the metal touch are relatively first outdoor engaging portions c, and the engaging portions d are relatively higher indoor than the first engaging portions c. The second engaging portion d is low.
A space partitioned by the metal pressing piece 25a and the resin pressing piece 25b in the lower pressing edge 25 forms an internal pressure space 38 communicating with the indoor side, and a plurality of hollow portions partitioned by the resin pressing piece 25b also form an internal pressure space. Moreover, the indoor side space partitioned by the metal pressing edge piece 25a and the metal lower collar 18 on the indoor side of the external pressure space 37 also forms an internal pressure space 39 set to the internal pressure.
In the vertical window 1, rainwater or the like may infiltrate from the contact surface between the outdoor packing 22 and the glass panels 15 or panel fitting grooves 18 a on both sides thereof. In that case, even if rainwater flows into the lower pressing edge 25 from the contact portion of the arcuate hook portion 25ab and the claw portion 18b of the second engagement portion c ′ that becomes a metal touch, and flows into the external pressure space 37, the drainage hole 36 can be drained.

The vertical window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next. Before that, a method for attaching the vertical window 1 in a building or the like will be described with reference to FIGS. 1 to 3. explain.
The frame 7 and the frame 14 of the shoji 9 are attached as a set to the building opening of the building from the indoor side. Alternatively, the frame body 7 is first attached to the housing opening, and then the housing 14 of the shoji 9 is attached to the frame body 7 from the indoor side. In this state, the handle 30 is fixed to the prospective surface 19ba on the indoor side of the vertical rod 12 on the hanging end side.
Next, when the glass panel 15 is housed in the housing 14, the glass panel 15 is held facing the housing 14 in FIG. 3. The vertical side end of the glass panel 15 on the handle 30 side is inserted and pushed into the panel fitting groove 19 a formed in the metal vertical rod 19 of the hanging vertical side rod 12 provided with the handle 30. Next, the other vertical side end portion of the inclined glass panel 15 is pushed into the vertical rod 13 on the hanging side, and is slid into the panel fitting groove 20a of the metal vertical rod 20 to be positioned.

Next, from the indoor side, the vertical pressing edge 28 is pushed in and attached to the hanging metal side vertical gutter 20. Similarly, the upper pressing edge 24 and the lower pressing edge 25 are pushed into the metal upper bar 17 and the metal lower bar 18 for mounting.
The vertical pressing edge 28, the upper pressing edge 24, and the lower pressing edge 25 are pushed into and fixed to the three parts of the metal vertical rod 20, the metal upper rod 17, and the metal lower rod 18 on the hanging side where the handle 30 of the shoji 9 is not installed. The glass panel 15 can be firmly attached to 14. In addition, the handle 30 does not interfere with the mounting of the glass panel 15.

Next, the operation of the vertical window 1 according to this embodiment will be described.
When rain water or the like is sprayed on the glass panel 15 of the vertical window 1, rain water or the like may permeate between the outdoor packing 22 and the glass panel 15 or the panel fitting groove 18 a in contact therewith. In this case, as shown in FIG. 4, rainwater flows down to the bottom of the panel fitting groove 18a and is stored. Then, rainwater permeates into the external pressure space 37 from the first engagement portion c between the panel fitting groove 18a and the metal pressing piece 25a of the lower pressing edge 25, that is, the metal touch of the arcuate hook portion 25ab and the claw portion 18b. To do.
At this time, since the inside of the external pressure space 37 partitioned by the metal pressing piece 25a of the lower pressing edge 25 and the lower piece portion 18c of the metal lower rod 18 is an external pressure, rainwater flows into the relatively low pressure indoor side through the lower pressing edge 25. I can prevent it.

And the rainwater which flowed in into the external pressure space 37 from the 1st engaging part c has the drain hole 36 formed in the bottom face of the lower piece part 18c below the 2nd engaging part d with comparatively low height. Therefore, it flows down to the metal lower frame 4a of the lower frame 4 through the drain hole 36 and is discharged to the outside. Moreover, it is possible to prevent water leakage from the second engagement portion d to the indoor side. Therefore, water does not collect at the bottom of the external pressure space 37.
In addition, the metal pressing piece 25a forming the external pressure space 37 and the wall surface of the metal lower bar 18 may condense due to the influence of outside air. In this case, the condensed water flows down to the bottom surface of the external pressure space 37, but is discharged to the outside in the same manner as rainwater through the drain hole 36 formed in the lower piece 18c on the bottom surface.

  As described above, according to the vertical extending window 1 according to the present embodiment, the bottom surface of the lower piece portion 18c of the external pressure space 37 partitioned by the metal pressing piece 25a of the lower pressing edge 25 and the metal lower setting 18 in the lower punch 11 of the shoji 9. Since the drainage hole 36 is provided in the outer pressure space 37, even if rainwater flows into the external pressure space 37 from the metal touch portion of the metal pressing piece 25a and the metal lower rod 18 or the condensed water flows down, the water is not allowed to enter the second engagement portion. In addition to preventing the water from flowing into the indoor side through d ′, it can be discharged from the lower frame 4 to the outside through the lower drainage hole 36 in the lower piece 18c, and water can be prevented from accumulating in the external pressure space 37.

  Note that the vertical window 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the gist of the present invention. In the following, modifications and the like of the present invention will be described, but the same or similar parts and components as those described in the above-described embodiments will be described using the same reference numerals.

Next, a modification of the embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a view of the metal pressing edge piece 25a of the lower pressing edge 25 attached to the indoor side of the lower arm 11 of the shoji 9 as viewed from the indoor side, and FIG. 6 is a view of the metal pressing edge piece 25a as viewed from the outdoor side.
5 and 6, the lower frame 4 of the frame body 7 and the vertical frame 6 on the suspension side are installed substantially orthogonally. Inside of the panel fitting groove 20a formed in the panel fitting groove 18a formed in the metal lower collar 18 of the lower collar 11 of the shoji 9 installed inside the metal lower frame 4a and the metal vertical fence 20 of the vertical collar 13 on the hanging side. Further, a glass panel 15 is installed. 5 and 6, the glass panel 15 is omitted.
The lower pressing edge 25 attached on the metal lower bar 18 shows a metal pressing edge piece 25a, and the resin pressing edge piece 25b attached thereon is omitted. Further, the vertical pressing edge 28 shown in FIG. 6 is provided with only the metal pressing piece 28a, and the resin pressing piece 28b is omitted.

In the lower pressing edge 25 shown in FIG. 5, as described in the above-described embodiment, an external pressure space 37 is partitioned and formed between the metal pressing edge piece 25 a and the lower metal lower bar 18. Since the metal pressing piece 25a and the metal lower bar 18 are made of, for example, an aluminum alloy and formed of an extruded shape, the external pressure space 37 extends in the longitudinal direction of the metal pressing piece 25a and opens at both ends thereof.
An airtight piece 40 having elasticity is installed in the gap between the metal pressing edge piece 25a forming the external pressure space 37 and the lower end portion of the metal vertical rod 20 at one end of the hanging side of the metal lower rod 18. Has been. Usually, the contact part between the both ends of the metal pressing edge piece 25a and the metal lower bar 18 and the metal vertical bar 20 is a metal touch. Therefore, there exists a subject that the influence on airtightness is large by the error of the length of the metal pressing edge piece 25a and the metal lower collar 18. However, in this modification, the airtightness between the end portions of the metal pressing piece 25a and the metal lower rod 18 and the metal vertical rod 20 can be stably secured by the airtight piece 40.

In this modified example, the airtight piece 40 includes, for example, a horizontally-oriented substantially square box-shaped first airtight piece portion 40a and a vertically-oriented rectangular box-shaped second airtight piece portion 40b provided on the panel fitting grooves 18a, 20a side. Are formed in a substantially L shape.
The upper surface of the first airtight piece portion 40a protrudes upward from the region having the external pressure space 37 of the metal pressing piece 25a, and the upper surface of the second airtight piece portion 40b is as high as the standing piece portion 25aa of the metal pressing piece 25a. It extends. Further, the lower surface of the airtight piece 40 extends downward so that the external pressure space 37 can be sealed by the first airtight piece portion 40a, and extends, for example, until it contacts the metal lower collar 18 of the lower frame 4.
Moreover, as shown in FIG. 6, the 2nd airtight piece part 40b of the airtight piece 40 protrudes in the corner | angular part of the panel fitting groove 18a and the panel fitting groove 20a. The 2nd airtight piece part 40b seals between the corner | angular part of the panel fitting groove | channels 18a and 20a which store the glass panel 15 with the 1st airtight piece part 40a, and indoor, and external air ventilates indoor side as an airtight line. Is preventing.

A plate-shaped holding frame 41 made of resin is installed on the metal pressing piece 25a side of the hermetic piece 40, and a box-like sponge 42 is in close contact with the metal vertical rod 20 side of the holding frame 41 as an elastic body. The sponge 42 is integrated by fitting and closely contacting an engagement piece 41 a provided on the holding frame 41. The airtight piece 40 is hermetically sealed by the elasticity of the sponge 42 so that the holding frame 41 is in close contact with the end of the external pressure space 37.
And the airtight piece 40 is similarly fitted in the clearance of the corner | angular part with the metal vertical rod 19 also in the other edge part by the side of the metal pushing edge piece 25a which forms the external pressure space 37, and the metal lower rod 18. Yes. Therefore, both ends of the external pressure space 37 extending in the longitudinal direction of the metal pressing piece 25a and the metal lower bar 18 are sealed in an airtight and liquidtight manner by the airtight pieces 40, respectively. In addition, the metal pressing piece 25a of the lower pressing edge 25 has a length equivalent to that of the metal lower bar 18 and is set to a length shorter by the thickness of the airtight piece 40 installed at both ends.

Accordingly, when the metal pressing piece 25a is installed on the metal lower bar 18 between the left and right metal vertical bars 19 and 20 of the casing 14 in the vertical extending window 1, airtightness is secured to the corners of both ends of the metal lower bar 18 in advance. Each piece 40 is installed.
Then, one end portion of the metal pressing piece 25a is inserted to press the holding frame 41 of the airtight piece 40 on one side. Next, the metal pressing piece 25a is elastically fitted between the airtight pieces 40 on both sides while pressing the holding frame 41 of the airtight piece 40 on the other side by pushing the other end. In the fitted state, the metal pressing piece 25a and the metal lower bar 18 are engaged by the first engaging part c and the second engaging part d.

As described above, the metal pressing piece 25a is pressed by the elasticity of each sponge 42 while being fitted between the airtight pieces 40 on both sides. Moreover, when the metal pressing piece 25a is fitted, the holding frames 41 of the airtight pieces 40 at both ends are pressed and brought into contact with each other in order to prevent damage such as the sponge 42 being caught by the end of the metal pressing piece 25a and being torn. it can. In addition, the airtight piece 40 can be compressed following the thermal contraction of the lower pressing edge 25, particularly the resin pressing edge piece 25b.
Then, the lower end portion of the right vertical pressing edge 28 is brought into contact with the upper surface of each airtight piece 40. The airtight pieces 40 at both ends of the metal pressing piece 25a can be hidden so as not to be visible from the outside by attaching the resin pressing piece 25b and the vertical hook 12 or the vertical hook 13b.

  According to the vertical extension window 1 according to this modification, the airtight pieces 40 are installed at both ends of the metal pressing piece 25a in the lower pressing edge 25, respectively, so that both ends of the external pressure space 37 between the metal pressing bar 18 are sealed.
