However, in the conventional protruding windows described in Patent Documents 1 and 2, a supporting structure (Patent Document 1 composed of a guide member and a slide member) that supports a face material so as to be able to project and retract substantially parallel to the frame body. And the parallel link mechanism of Patent Document 2) are complicated, resulting in an increase in the number of parts and an increase in manufacturing cost.
Furthermore, the conventional protruding window has a problem in that the appearance design of the window is impaired because a complicated support structure is exposed at the opening of the frame when the face material is opened.

  An object of the present invention is to provide a joinery that can have a simple structure and that does not cause an increase in cost and that can have a good appearance.

The joinery of the present invention includes a frame having an opening and a face material supported by the frame, a closed position where the face material closes the opening of the frame, and a prospective direction of the frame It is a protruding-type fitting provided so as to be able to open and close between an open position protruding to one side, and is opposed to each other across the opening at the opening edge forming the opening of the frame At least one pair of support arms, one end side of each of the pair of support arms is rotatably connected to the opening edge, and the other end side is rotatably connected to the face material. A plurality of sets of support arms are provided at positions spaced apart from each other along the longitudinal direction of the opening edge, and a pair of support arms in at least one of the plurality of sets is synchronized to synchronize their rotations. are connected by means, said surface material The other end side connecting portion of the support arm when in the closed position and the other end side connecting portion of the support arm when the face material is in the open position are axes along the longitudinal direction of the opening edge. And it is located in the substantially symmetrical position of a prospective direction with respect to the axis line which passes along the one end side connection part of the said support arm .
In addition, the joinery of the present invention includes a frame having an opening and a face material supported by the frame, and a closed position where the face material closes the opening of the frame, It is a protruding-type fitting provided to be openable and closable between an open position protruding to one side in the prospective direction, and the opening edge that forms the opening of the frame sandwiches the opening. At least a pair of support arms opposed to each other is provided, each of the pair of support arms is rotatably connected to one end side of the opening edge and rotatably connected to the face material of the other end side, A plurality of pairs of support arms are provided at positions spaced apart from each other along the longitudinal direction of the opening edge, and the pair of support arms in at least one of the plurality of sets synchronize with each other in rotation. Connected by synchronization means, before The opening of the frame is formed in a substantially rectangular shape from the upper and lower and left and right opening edges, and the pair of support arms is provided in two sets on the upper and lower sides of the left and right opening edges. The synchronization means may be constituted by a connecting member that connects a pair of support arms provided at the lower part of the set.

Here, the frame body may be fixed to a housing such as a building, or the frame body itself may be supported by the housing or the like so as to be opened and closed.
Moreover, as a face material, what was formed from board | plate materials, such as a glass panel and a resin panel, may be used, and the shoji formed by inserting a board | plate material in the inside which assembled the upper, lower, left, and right eaves members around 4 times may be sufficient.
Furthermore, as at least a pair of opening edges to which one end of the support arm is rotatably connected, for example, when the opening of the frame is formed in a rectangular shape, the left and right sides forming the opening These may be two end edges (vertical sides) or upper and lower two end edges (horizontal sides). Furthermore, one end of the support arm may be connected to all of the four upper, lower, left and right edges. In this case, the support arms connected to the upper and lower opening edges are paired, and the left and right opening ends The support arms connected to the edges may be a pair.
Moreover, as a synchronizing means which synchronizes a pair of support arms, you may be comprised by the connection member etc. which connect support arms directly, and used the gear, the belt, the rope (wire), the pulley, the pulley, etc. It may be connected via interlocking means.

According to the present invention as described above, the frame body and the face material are directly connected by the support arm, and the face material can be projected and retracted by the rotation of the support arm. There is no need to use it, and the support structure can be simplified, the number of parts can be reduced, and the manufacturing cost of joinery can be suppressed. That is, in the conventional support structure, the face material is projected and subtracted linearly in the prospective direction with respect to the frame body by the mechanism constituted by the guide member and the slide member and the parallel link mechanism. The face material is projected and retracted along the rotation trajectory (arc) of the arm. And, by appropriately setting the length of the support arm (distance between the one end side connecting portion and the other end side connecting portion), the clearance between the frame body and the face material, it does not hinder the opening and closing movement of the face material. Thus, the support structure can be simplified. In addition, if the length is the same for each of the multiple sets of support arms, the face material can be projected and subtracted while maintaining parallelism with the frame, and the length can be changed appropriately for each of the multiple sets of support arms. By doing so, the face material can be projected and retracted at an angle to the frame.
In addition, by providing a plurality of sets of support arms at positions spaced apart from each other along the longitudinal direction of the opening edge of the frame body, the support structure is installed so as to avoid a conspicuous position near the center of the opening edge. The degree of freedom can be increased, and the appearance design of the joinery can be improved by making the support structure inconspicuous with the face material opened.
Further, since at least a pair of support arms are connected to each other by a synchronizing means, only one of the pair of support arms rotates and the other member does not rotate during the opening / closing operation, and the face material is a frame. Therefore, it is possible to prevent an abnormal opening and closing that is twisted and sunk with respect to the opening, and to improve the operability of the opening and closing operation.

At this time, in the fittings of the present invention, when configured to the other end side connecting portion of the support arm between a closed position and an open position of the surface material is substantially line symmetrical positions on the estimated direction, the face material in the closed position The face material is projected at substantially the same opening position as the linear projection in the prospective direction, and the design of the joinery in the opened state and the operability of the opening / closing operation can be improved.

Further, in the fittings of the present invention, by providing the support arm to the left and right opening edge of the opening mouth portion, rotatably connected support arm and the opening edge and face material and is rotated about a substantially horizontal pivot axis Thus, the support arm is rotated vertically along the vertical plane. Then, the lower support arms at the left and right opening edges are connected to each other by a connecting member so that the rotation of these supporting arms is synchronized, and the connecting member is positioned near the lower end edge of the face material or the face material. If it provides in the position covered with the lower end edge of this, a connection member can be made not conspicuous and the designability of the fitting at the time of opening can be improved further.

Furthermore, in the joinery of the present invention, a slide member that is slidably supported along the prospective direction of the frame body and slides the slide member at a substantially intermediate position in the height direction at the left and right opening edges. It is preferable that an operation member is provided, and the face member is locked to the slide member so as not to move in a prospective direction and to move in a vertical direction.
According to such a configuration, by operating the operating member and sliding the slide member in the prospective direction, the face material that is immovably locked in the prospective direction with respect to the slide member is protruded and submerged, Easy to open and close. And even if the face material in the middle of opening and closing moves in an arc shape along the rotation trajectory of the support arm as described above, the face material is locked so as to be movable in the vertical direction with respect to the slide member. Smooth opening and closing operations can be realized without restricting the movement of the face material.

Furthermore, in the joinery of the present invention, a vertical piece extending in the vertical direction is provided at the end of the slide member on the face material side, and the face material is expected at two places, an upper end and a lower end of the vertical piece. It is preferable to be locked so that it cannot move in the direction and can move in the vertical direction.
According to such a configuration, the upper and lower portions of the vertical piece provided on the slide member are locked to the face material, and the face material is pushed and pulled at these two locations to move into and out of the upper part of the face material. And the abnormal opening and closing which one side of the lower part rotates and the other does not rotate and tilts and sinks with respect to the frame body can be prevented, and the operability of the opening and closing operation can be further improved.

Further, in the fitting of the present invention, the frame body is constituted by a door body that can be opened and closed at the entrance of the building, and the face material is provided to be able to open and close by projecting to the outside of the door body. It is preferable to be a door.
According to such a configuration, the door body can be configured so as to be able to project and retract, so that the door having the above-described effects can be configured, and the door body is closed and locked. If the face material is opened, it is possible to carry out ventilation and ventilation while maintaining crime prevention, and a comfortable indoor environment can be obtained. .

The door is capable of entering and exiting and is configured to have crime prevention properties by being locked. In addition, in each figure, illustration of the outer wall of the building in which the door 1 is attached, the door frame fixed to the outer wall, etc. was abbreviate | omitted.

The door 1 includes a door body 2 as a frame body formed by combining metal plates and formed into a substantially rectangular shape, a shoji 3 as a face material supported by the opening 2A portion of the door body 2, and a door. A door frame (not shown) that supports the body 2 through a hinge so as to be opened and closed is configured. In the substantially central portion of the door body 2, an opening 2 </ b> A formed in a vertically long rectangular shape from upper, lower, left and right opening edges 21, 22, 23 (see FIGS. 5 and 6) is provided.
The shoji 3 is configured by fitting a glass panel 34 into an interior in which an upper collar 31, a lower collar 32, and left and right vertical collars 33 are assembled in four rounds. The shoji 3 includes a closed position (the position shown in FIGS. 3 and 4) that closes the opening 2 </ b> A of the door 2, and an open position (the position shown in FIGS. 5 and 6) that protrudes outside the prospective direction of the door 2. It is supported so that it can move in and out. The upper end 31 of the shoji 3 is formed with a water stop piece 31A protruding toward the indoor side, and the lower end 32 and the left and right vertical anchors 33 protrude toward the indoor side and are covered with a net. Ventilation portions 32A and 33A are formed. The water stop piece 31A and the vents 32A and 33A are provided with the upper and lower ridges 31 and 32 of the shoji 3 in the open position, and the vertical and horizontal opening edges 21, 22 of the door body 2. 23, so that it is possible to carry out ventilation and ventilation through the ventilation portions 32A and 33A while preventing rain from entering from above and preventing insects and dust from entering. ing.

The door 1 is provided with a shoji support section 4 that supports the shoji 3 so as to be able to project and retract in a prospective direction, and a shoji operation section 5 for opening and closing the shoji 3. Hereinafter, the structure of the shoji support part 4 and the shoji operation part 5 will be described in detail with reference to FIGS.
FIG. 7 is a cross-sectional view showing the shoji support section 4, and FIGS. 8A and 8B are side views showing the operation of the shoji support section 4. FIG. 9 is a cross-sectional view showing the shoji operation unit 5. 7 and 9 show the shoji support section 4 and the shoji operation section 5 in a state where the shoji 3 is opened to a maintenance position described later.

  The shoji support part 4 has two pairs of two facing each other across the opening 2A on the upper and lower parts of the door body 2 on the left and right opening edge (vertical opening edge) 23 that are spaced apart vertically. A set (4 places) is provided. As shown in FIG. 7, these shoji support portions 4 include a frame side bracket 41 fixed to the opening edge 23, a shoji side bracket 42 fixed to the vertical rod 33 of the shoji 3, and these frame side brackets. 41 and a shoji-side bracket 42 and support arms 43 each having both ends pivotally supported. One end of the support arm 43 is connected to the frame side bracket 41 by a pin (one end side connecting portion) 44 so as to be rotatable about a substantially horizontal rotation axis, and the other end side is a pin (other end side connecting portion). 45 is connected to the shoji side bracket 42 so as to be rotatable about a substantially horizontal rotation axis, and is configured to be rotatable in a substantially vertical plane.

The frame-side bracket 41 is formed from a bent plate material so as to have a substantially U-shaped cross section, and one side surface portion 41A facing the screw is fixed to the opening edge 23 of the door body 2 with a screw, and the other side surface portion 41B is provided with a support arm 43. One end side is connected. The other side surface upper surface of the frame side bracket 41 is formed in an arc shape, and this upper surface can guide the protruding pin 43A provided to protrude from the side surface of the support arm 43. .
In addition, a pin 44 of the support arm 43 of the shoji support section 4 (upper shoji support section 4A) provided at the upper part of the left and right opening edge 23 is sandwiched between the other end side pin 45 and an end section on the opposite side. When the shoji 3 is opened up to the maintenance position, a contact surface portion 43B that contacts the back surface portion 41C of the frame side bracket 41 is formed.
On the other hand, the support arms 43 of the shoji support section 4 (lower shoji support section 4B) provided at the lower portions of the left and right opening edges 23 pass through the other side surface section 41B of the frame side bracket 41 and below the shoji 3 The rotating shafts (connecting members) 46 extending along the lower side of the flange 32 are connected to each other, and the rotating shaft 46 constitutes a synchronizing means for synchronizing the rotation of the pair of support arms 43.

  As shown in FIG. 8, the pin (other end side connecting portion) 45 of the support arm 43 in each of the above shoji support portions 4 is configured to rotate while drawing an arcuate rotation locus C. The support arm 43 extends along the longitudinal direction of the opening edge 23 in a state where 3 is in a closed position (indicated by a one-dot chain line in the figure) and a state where the shoji 3 is in an open position (indicated by a solid line in the figure). It is located at a substantially symmetrical position in the prospective direction with respect to the axis A passing through the first pin (one end side connecting portion) 44. That is, the shoji 3 in the closed position and the shoji 3 in the open position are positioned at substantially the same height position, and the shoji 3 being opened or closed is slightly above the closed position and the open position. It passes through the position shifted to However, the turning radius of the support arm 43 (distance between the pins 44 and 45) is set to be relatively large (for example, twice or more) as compared with the protruding and retracting distance of the shoji 3 so that the shoji 3 The amount of shift to the upper side can be made extremely small. Specifically, for example, if the distance of the shoji 3 is set to 25 mm and the turning radius of the support arm 43 is set to about 65 mm, the shift amount of the shoji 3 upward at the open / close intermediate position is about 1 mm. In this way, the locus of the shoji 3 is approximated to the locus of the linear movement along the prospective direction, so that a big problem arises even if the amount of shift upward of the shoji 3 is almost ignored in design. I can not.

Next, as shown in FIG. 3 to FIG. 6 and FIG. 9, the shoji operation portion 5 is a base portion 51 fixed to the indoor side surface at a substantially intermediate position in the height direction at the left and right opening edge 23 of the door body 2. An operation arm 52 supported rotatably on the base portion 51 and slidable in a prospective direction; and connected to the operation arm 52 so as to be rotatable and slidable in a prospective direction with respect to the base portion 51. And a biasing means (not shown) for biasing the slide member 53 toward the outdoor side.
The substantially lower half of the base portion 51 is a slide base portion 51A that is divided and provided slidably downward, and can be slid when moving the shoji 3 to the maintenance position as will be described later. .

  The pair of left and right operation arms 52 are connected by an operation handle 54, and the operation arm 52 and the operation handle 54 constitute an operation member of the present invention. Then, by operating the operation handle 54 to rotate the operation arm 52 from the state of FIGS. 3 and 4 to the state of FIGS. 5 and 6, the slide member 53 urged by the urging means moves toward the outdoor side. The slide member 53 is slid toward the indoor side against the urging force of the urging means by sliding and rotating the operation arm 52 in the opposite direction. Further, at the two positions where the slide member 53 is slid to the indoor side or the outdoor side, the outdoor side surface of the operation arm 52 abuts on the indoor side surface of the slide base portion 51A, so that the operation arm 52 and the slide member 53 are It is designed to be positioned.

  A locking groove 53A is formed at the distal end of the outdoor side of the slide member 53. The locking groove 53A is open upward and is elongated vertically. In the locking groove 53A, the height direction of the vertical rod 33 of the shoji 3 is formed. A locked pin 55 fixed at a substantially intermediate position is inserted. And the to-be-latched pin 55 is locked by the locking groove 53A of the slide member 53 so that it cannot move in the prospective direction but can move in the vertical direction. Therefore, as the slide member 53 is slid by the rotation of the operation arm 52, the shoji 3 connected to the slide member 53 via the locking groove 53A and the locked pin 55 is projected and retracted in the expected direction. It has become. As described above, the shoji 3 is displaced upward during the projecting and retracting movement, but the upward displacement is absorbed by the locked pin 55 sliding up and down in the locking groove 53A. The sliding movement of the shoji 3 is not restricted.

As shown in FIGS. 10 and 11, the shoji 3 supported by the shoji support section 4 and the shoji operation section 5 as described above can be opened to a maintenance position that protrudes further to the outdoor side than the open position. It has become.
10 and 11 are a longitudinal sectional view and a transverse sectional view showing the door 1, respectively, and show a state in which the shoji 3 is opened to the maintenance position.
In the state where the shoji 3 is opened to this maintenance position, by inserting a hand or a tool through the gap formed between the door body 2 and the shoji 3, the shoji support 4 is released and the shoji 3 is opened. It can be removed from the body 2 or the nets of the ventilation portions 32A and 33A can be exchanged or cleaned.

  In order to open the shoji 3 to such a maintenance position, first, the operating arm 52 is rotated downward as shown in FIG. 5, and the slide base 51A is operated as shown in FIG. Slide down to the bottom. As a result, the contact between the slide base 51A and the operation arm 52 is released, and the operation arm 52 can slide to the outdoor side. Next, by pushing the operating arm 52 to the outdoor side, the slide member 53 is slid to the outdoor side, and the shoji 3 connected to the slide member 53 is projected to the maintenance position along with this slide. At this time, the support arm 43 of the shoji support unit 4 rotates to the position indicated by the two-dot chain line in FIG. 8, and the pin (other end side connection unit) 45 moves downward along the rotation locus C. That is, the entire shoji 3 is lowered downward, but the locked pin 55 of the shoji 3 slides downward in the locking groove 53A of the slide member 53, so that the movement of the shoji 3 is not restricted. It has become.

According to this embodiment, there are the following effects.
(1) That is, the opening edge 23 of the door body 2 and the vertical rod 33 of the shoji 3 are directly connected by the support arm 43, and the shoji 3 is projected and retracted along the rotation trajectory of the support arm 43. The shoji 3 can be supported without using a complicated link mechanism or the like, the structure of the shoji support 4 can be simplified, the number of parts can be reduced, and the manufacturing cost can be suppressed. Furthermore, since the shoji support part 4 is provided in the upper part and the lower part of the right and left opening edge 23, the shoji support part 4 can be made inconspicuous with the shoji 3 opened, and the appearance design of the door 1 is good. Can be.

(2) Further, the position of the pin (the other end side connecting portion) 45 of the support arm 43 is substantially line symmetric with respect to the axis A in the closed position and the open position of the shoji 3. Therefore, the shoji 3 becomes substantially the same height position in the closed position and the open position, and the design of the door 1 in the opened state and the operability of the opening / closing operation of the shoji 3 can be improved. Furthermore, the amount of shift of the shoji 3 during opening and closing movement can be reduced upward from the closed position and the open position, and the clearance between the opening edge 23 of the door 2 and the shoji 3 can be reduced.

(3) Further, the support arm 43 is supported by the left and right opening end edges 23 and rotates in a substantially vertical plane, and is configured to support the shoji 3 in the open position in a state indicated by a solid line in FIG. Therefore, since most of the weight of the shoji 3 is transmitted to the door body 2 as the axial force of the support arm 43, a large bending stress does not act on the support arm 43, and the member cross section of the support arm 43 can be reduced. In this respect as well, an increase in manufacturing cost can be suppressed. Further, in a state where the shoji 3 is opened at the maintenance position, the abutment surface portion 43B formed on the support arm 43 of the upper shoji support portion 4A abuts on the back surface portion 41C of the frame side bracket 41. Therefore, the shoji 3 opened to the maintenance position can be reliably supported.

(4) Since the lower support arms 43 at the opening edge 23 are connected to each other by the rotation shaft 46, only the left and right support arms 43 rotate when the shoji 3 is opened and closed. The shoji 3 does not twist left and right without the other turning, and the operability of the opening / closing operation can be improved. Furthermore, since the rotating shaft 46 is provided along the lower side of the lower arm 32 of the shoji 3, the rotating shaft 46 can be made inconspicuous and the design of the door 1 when the shoji 3 is opened is further improved. be able to.

(5) Since the shoji 3 is opened and closed by the shoji operation unit 5 provided at a substantially intermediate position of the opening edge 23 separately from the shoji support unit 4, the shoji operation unit 5 has almost no weight of the shoji 3 Opening and closing operations can be performed smoothly with a small operating force without acting. And since the to-be-latched pin 55 of the shoji 3 is slidably latched up and down by the latching groove 53A formed in the slide member 53 of the shoji operating portion 5, the shoji 3 in the middle of opening and closing is supported by the support arm 43. Even if the arc moves along the rotation trajectory C and shifts upward, the shift can be absorbed by the locking groove 53A, and a smooth opening / closing operation can be realized without restricting the movement of the shoji 3. Can do.

(6) In the state in which the shoji 3 is opened to the open position, the upper and lower eaves 31 and 32 and the left and right vertical eaves 33 of the shoji 3 Since the gap is covered with the water stop piece 31A and the ventilation portions 32A and 33A of the shoji 3, the ventilation and ventilation can be carried out through the ventilation portions 32A and 33A while preventing the intrusion of rain and the entry of insects, etc. Can improve the habitability. Furthermore, if the shoji 3 is opened to the maintenance position by operating the shoji operation section 5, maintenance work such as removing the shoji 3 from the door 2 and cleaning the ventilation parts 32A and 33A can be easily performed. .

[Second Embodiment]
Next, 1A of doors which are the fittings which concern on 2nd Embodiment of this invention are demonstrated based on FIG.

It is configured. A vertical piece 53 </ b> B that extends vertically along the vertical rod 33 of the shoji 3 is provided at the outdoor end of the slide member 53. Then, two locking grooves 53A are formed in the upper and lower ends of the vertical piece 53B so as to be long in the vertical direction like the locking grooves 53A. Further, the vertical pin 33 of the shoji 3 is provided with two locked pins 55 similar to the locked pin 55, and these locked pins 55 are respectively provided in the two locking grooves 53A. It is locked so that it cannot move in the prospective direction and can move in the vertical direction.

  In such a shoji operation section 5, the shoji 3 projects in the expected direction through the vertical piece 53 </ b> B, the locking groove 53 </ b> A, and the locked pin 55 as the slide member 53 slides by the rotation of the operation arm 52. It is supposed to be moved. As in the first embodiment, even when the shoji 3 is shifted upward along the pivotal trajectory of the support arm 43 during the projecting and retracting movement, or even when the shoji 3 is lowered during the movement to the maintenance position, the locked pin The sliding movement of the shoji 3 is not restricted by 55 sliding up and down along the locking groove 53A.

According to the present embodiment, the following effects are obtained in addition to the effects (1) to (6) described above.
(7) That is, the locked pin 55 of the shoji 3 is latched by the two upper and lower retaining grooves 53A of the vertical piece 53B provided on the slide member 53, and the shoji 3 is pushed and pulled at these two locations. By immersing, the shoji 3 can be moved linearly along the prospective direction, and the abnormal opening and closing that the shoji 3 is tilted up and down can be prevented, and the operability of the opening / closing operation is further improved. Can be.

[Third Embodiment]
Next, a door 1B, which is a fitting according to a third embodiment of the present invention, will be described with reference to FIGS.
