In the following, the present invention will be described in more detail with reference to the example of the drawings. A is an aluminum fold that can be suitably installed at the opening of a structure such as a solarium that also serves as an outdoor space formed on a veranda or a wood deck. The tatami door B is a locking device, and in this example, the foldable door A is provided with the upper hanging side 21 and 22 on the side of each side of the adjacent panel 2 on the upper hanging side. The front and back finding surfaces of the vertical gutter 21 are connected in a V-shaped foldable manner directly or via a connecting frame so as to be close to each other and facing each other, and the vertical hanger 21 or the connecting frame on the upper suspension side is connected to the upper and lower sides of the outer frame 1. It is formed as having a single or a plurality of adjacent panels 2 by supporting the frame 11 and 12 so as to be able to run in the longitudinal direction, and the locking device B in the folding door A is Part of folding door A or Be open folded the adjacent panels 2 parts as those capable released and the locking to lock the panel, the lock device B this time, hanging on in the adjacent panel 2 Oritatamito A The projecting member 3 projecting from the one vertical rod 21 toward the finding surface of the other hanging rod 21 on the upper suspension side, and the projecting member advancing and retreating through the finding surface of the other vertical rod 21 on the upper hanging side Built in the receiving opening 4 and the other vertical rod 21 on the upper suspension side, the outer frame 1 descends downward in the other vertical rod 21 on the other side of the upper suspension side by pressing engagement of the protruding member 3 entering the receiving opening 4. The lower frame 12 is freely engageable at the lower end, and is lifted upward by releasing the retraction of the projecting member 3 in the receiving opening so as to be freely disengaged from the lower frame 12 and the pressing engagement. Protruding member 3 approaching to adjacent panel 2 The distance between the opposing facing surfaces of the vertical suspension 21 on the upper suspension side is reduced by the compression of the protruding surface 3 in the direction in which the disengagement of the projecting member 3 is released. The lock member 5 is provided.

  In this example, the folding door A is composed of a pair of panels which are assembled into vertically long rectangles by upper and lower horizontal fences and left and right vertical fences made of an aluminum extruded material, and a transparent plate such as glass is mounted in the vertical frames. 2 are connected directly by hinges 23 arranged at a plurality of positions on the upper and lower sides of each of the adjacent vertical ones, that is, the escape vertical ones 22, so that the front and back sides of the upper vertical side can be found. V-shaped folds that are close to each other and can be opposed to each other, and the vertical rods on the non-adjacent side of each panel 2 located at both ends of the pair of connected panels 2, that is, the vertical rod 21 on the upper suspension side, Similarly, the upper and lower frames 11 and 12 of the outer frame 1 made of an aluminum extruded material are supported by an upper suspension through an upper suspension slider 24 at the upper end and an anti-roller roller 25 at the lower end so that the upper and lower frames can travel in the longitudinal direction. Multiple, especially many There as those freely open and close the opening of the outer frame 1 by placing a pair of panels 2 in the width direction of the outer frame 1.

  In this example, each of the pair of panels 2 arranged in a large number is not connected to each other, without connecting the vertical rods 21 on the upper suspension side adjacent to each other. Each pair of panels 2 in the door A constitutes an opening / closing unit in the folding door A, and each of the paired panels 2 can freely be folded in an independent V-shape, so that the folding door A of the present example has a width direction of the outer frame 1. If the upper and lower frames 11 and 12 are used as a reference, it is possible to open and close the door from its arbitrary position in the longitudinal direction, to open and close it from the end, and to partially open and close the arbitrary position. Only lightly opens and closes at the arrangement position, thereby allowing people to enter and exit and to ventilate at the arrangement position. Although not shown in the drawings, the vertical suspension 21 on each of the pair of panels 2 constituting the opening / closing unit body is, for example, an airtight means by fitting such that one is a fitting protrusion and the other is a fitting groove. Alternatively, if the airtight material arranged on both sides is provided with an airtight means by an airtight material that contacts the other, the space between each vertical suspension on the upper suspension side is sealed in the width direction of the outer frame, and the airtight or watertight as the inner and outer partition bodies It is also possible to ensure airtightness or watertightness by providing an airtight means, for example, using an airtight material, between the escape side vertical shafts directly connected via the hinge 23. Can do.

In the locking device B, when the V-shaped folding of the pair of panels 2 is performed, the locating surfaces of the vertical hanging rods 21 located at both ends thereof are closely opposed to each other, and the locating surfaces are separated when they are extended. Thus, the pair of panels 2 are locked with respect to the lower frame 12 by the close opposition at the time of folding and the separation at the time of extension, and the swinging due to the wind pressure and vibration is prevented. The projecting member 3 installed on the one vertical gutter 21 in the opened state of the fold is entered into the other vertical gutter 21 through the receiving opening 4 of the other vertical gutter 21, and the lock member 5 built in the same is installed. To the lower frame 12 of the other vertical rod 21, and the protruding member 3 is withdrawn when extended to engage the lock member 5 and release the lock. At this time, the lock is performed on the other vertical rod 21, but by providing the protruding member 3 with a connecting function to the other vertical rod 21 or the lock member described later, As a result of connecting to the other vertical shaft 21 that is locked, the pair of panels 2 can be integrated to lock the lower frame.

As described above, the locking member 5 pressing engagement of the projecting member 3 is performed by compressing the distance between the facing surfaces of the vertical hanging rods 21 on the adjacent suspended panel 2 in the direction in which the locking member 5 faces. The retraction of the protruding member 3 with the lock member 5 disengaged is performed as described above by expanding the distance between the finding surfaces in the direction of the finding surface separation. That is, when the pair of panels 2 are folded in a V-shape, when the distance between the vertical hanging rods 21 on the upper suspension side remains large, the projecting member 3 and the lock member 5 are still in the disengaged state, The inter-finding distance and the projecting member 3 are locked so that the projecting member 3 is pressed and engaged with the lock member 5 by compressing the distance between the prongs so that both the vertical rods 21 are strongly pressed by the fingertips. The projecting member 3 and the lock member 5 are arranged according to the distance between the finds by adjusting the positional relationship of the members 5. Therefore, in the locking device B of the present example, the folding door A is opened / closed and locked or released, and the pair of panels 2 are folded at an arbitrary position of the outer frame 1 to fold the door A. Even if a part of the pair is opened, the pair of panels 2 maintains a state of being movable in the longitudinal direction between the upper and lower frames 1. For example, by moving the pair of panels 2 to one side of the opened opening, By applying pressure to both the vertical shafts 21, the locking can be performed at the one side position, and each pair of panels is gathered in one place even when fully opened to a single open state or double open state. In this state, if both of the downspouts 21 on the opening side are strongly pressed, it is possible to perform the locking in the folded state without performing individual operations.

  In the locking device B of this example, the pressing member 3 is pressed and disengaged by the protruding member 3, and the pressing member 33 is provided at the tip of the protruding member 3 in the protruding direction, and the locking member 5 is moved downward from above. Inclined portions 63 that are inclined downward toward the protruding member 3 side are arranged, and the pressing portion 33 slides in contact with the inclined portion 63 of the lock member 5 by moving the protruding member 3 in the horizontal direction. The upward movement of the lock member 3 due to the disengagement of the protruding member 3 is caused by urging the lock member 5 upward to the other vertical rod 21 on the upper suspension side. It is assumed that it was built by its upward biasing force by incorporating it.

  That is, the projecting member 3 of this example includes, for example, a fixed base 31 that is screw-fixed, for example, on the surface of the vertical rod 21 on the upper suspension side, and a plate-like pressing projecting piece 32 that protrudes orthogonally from the fixed base 31 For example, a molded member having a T-shaped cross section integrally formed of metal or hard resin. At this time, the projecting member 3, particularly the plate-shaped pressing projecting piece 32 has its projecting direction tip from the upper end. The pressing part 33 is formed by the inclined surface inclined downward so as to form a side trapezoid that is inclined downward so as to reduce the lower side toward the lower end, and the upper side and the lower side of the pressing protrusion 32 are respectively described above. It is assumed that a locking recess 34 for connection to the other vertical rod 21 and the lock member 5 is arranged.

  The receiving opening 4 of this example is formed by punching and forming as a vertically long hole by a press in accordance with the installation position of the projecting member 3 on the surface of the other vertical rod 21 on the upper suspension side. In order to prevent the edge from being exposed, it is provided with a cap 41 integrally fitted with, for example, synthetic resin or metal, for covering the edge through which the opening for receiving the protruding member 3 is formed. is there. The opening of the cap 41 is vertically long according to the receiving opening 4 and has a lateral width slightly wider than the thickness of the protruding member 3, particularly the thickness of the plate-like pressing protrusion 32. When the panel 2 is folded and extended, the projecting member 3 is inserted into the receiving opening 4 or the opening of the cap 41, so that the projecting member 3 can absorb the rotation of the projecting member 3 in and out. , The smooth and reliable advancement and retraction of the projecting member 3 and the locking and unlocking operations thereby are ensured.

  The other vertical gutter 21 in which the receiving opening 4 is arranged is provided with a locking recess 34 arranged on the upper side of the protruding member 3, particularly the plate-like pressing protrusion 32, inwardly toward the upper end position of the receiving opening 4. A locking member 42 to be locked is arranged, and the locking member 42 can be installed on the other vertical shaft 21 as a single member. In this example, the locking member 42 is For example, the cap 41 is integrally formed with the cap 41. That is, the locking member 42 has a bar-like shape that protrudes toward the inside of the vertical rod 21 on the back surface of the upper end of the cap 41 and has a downward locking protrusion at the tip, and protrudes to the other vertical rod 21. When the member 3 is entered and the locking of the locking member 5 is completed, the locking member 5 is locked to the locking recess 34 on the upper side of the plate-like pressing protrusion 3, and the locked state is maintained on the upper side of the protruding member 3. It is intended to connect both downsides.

  The lock member 5 of the present example includes a slide guide 51 fixed inside the other vertical rod 21 on the upper suspension side, and a spring 56 that is slidably held by the slide guide 51 and interposed therebetween. The rod 6 is formed with an engaging member 62 for pressing engagement of the projecting member 3 and a lower portion of the engaging member 62 downward. The lower frame locking member 69 which is installed with force and has the cushion material 7 at the lower end is provided.

  The slide guide 51 of this example is installed in the inner wall of the other vertical shaft 21 by, for example, screwing from the side, and guides the rod 6 to slide up and down, and the rod 6 is moved upward. In this example, the slide guide 51 has a guide base 52 integrally formed of synthetic resin or metal, and a U-shaped cross section above the guide base 52. It is assumed that the guide groove 53 and the compression spring serving as the spring 56 housed in the lower housing portion 55 are provided. At this time, the guide groove 53 having the U-shaped cross-section is provided with guide through holes 54 provided vertically on both side walls thereof, and the guide groove 53 and the guide through holes 54 allow the guide groove 53 to be disposed in the vertical rod 21. The rod 6 is guided in a fixed position and is stably slid up and down. When the rod 6 is locked by a compression spring, the rod 6 is urged upward, and the rod 6 is released when the lock is released. Is automatically raised so that unlocking can be smoothly and reliably performed.

  The rod 6 of this example includes an engaging member 62, a storing portion 66 for storing a compression spring disposed below the engaging member 62, a compression spring 67 stored in the storing portion 66, and the storing portion 66 from the engaging member 62. A guide bar 68 that hangs down so as to penetrate vertically, a lower frame lock member 69 that is arranged to be movable up and down on the engaging member 62 by guidance of the storage portion 66 and the guide bar 68, and a lower end of the lower frame lock member 69 The installed cushioning material 7 is provided. The engagement member 62 and the storage portion 66 of the present example are formed by integrally molding synthetic resin or metal so as to form the rod base portion 61, while the synthetic resin or metal guide bar 68 is also stored in the storage portion 66. The upper wall is screwed and suspended in the storage portion 66, and a retaining protrusion disposed at the lower end of the guide bar 68 is made engageable with the upper end of the guide bar receiving hole of the lower frame locking member 69, thereby allowing the guide bar to be engaged. A lower frame lock member 69 is supported on the bar 68 so as to be movable up and down, and the lower frame lock member 69 is provided with a synthetic resin cushion material 7 having elasticity so as to cover at least the lower surface thereof, for example. It is installed so that the lower end is fitted. At this time, since the compression spring 67 is interposed between the engaging member 62 and the lower frame locking member 69, the lower frame locking member 69 receives its urging force in a direction away from the engaging member 62, thereby The lower frame 12 is resiliently locked.

  At this time, the engaging member 62 has a plate-like or block-like shape having a U-shape on the side surface, for example, by disposing a downward groove in the middle so as not to contact the storage portion 66 of the slide guide 51. An inclined portion 63 inclined downward from the upper end of the vertical shaft 21 on the receiving opening 4 side to the middle position is disposed, and the inclined portion 63 is formed as an inclined guide groove having both side walls by raising both end edges thereof. Further, slide projections 64 are formed on both ends of the slide guide 51 so as to protrude from both sides so that the engaging member 62 has a T-shaped cross section. At this time, at the lower end of the inclined guide groove, a connecting portion 65 extending between both side walls is disposed so as to close the inclined guide groove, and the upper end of the connecting portion 65 is formed into a cross-sectional mountain shape, thereby pressing the protrusion of the protruding member 3. A locking protrusion that can be locked is disposed in a locking recess 34 disposed on the lower side of the piece 32.

  In the slide guide 51, the end of the engaging member 62 of the rod 6 is fitted in the guide groove 53, and slide protrusions 64 on both sides thereof are respectively inserted into the guide through holes 54 formed on both side walls of the guide groove 53. By engaging and guiding the engaging member 62 by the guide groove 53 and the guide through hole 54, the engaging member 62 is integrated with the slide guide 51 so as to be movable up and down to form the lock member 5, and the lock member 5 Is installed in the other vertical gutter 21.

In the locking device 5 of the present example formed in this way, when the pair of panels 2 are folded in a V shape, the pair of panels is provided by the space between the hinges 23 connecting the escapement vertical rods 22. 2 and the vertical hanging rod 21 on the upper suspension side are parallel to each other, and the protruding member 3 partially enters the other vertical rod 21 so that the upper end of the pressing portion 33 contacts the lower end of the inclined guide groove of the engaging member 62. However, as shown in FIG. 2, in this state, the folding of the pair of panels 2 and the locking device B are not interlocked and are not locked. At this time , in the opened state where the panel 2 is folded, both of the vertical supports 21 on the suspension support side are compressed in the proximity direction so that the distance between the vertical planes 21 between the vertical supports 21 is compressed with a fingertip. As a result of the further advancement of the protruding member 3 that has entered, the entire pressing portion 33 of the pressing protrusion 32 slides with the inclined guide groove upward so that the pressing protrusion 32 is engaged with the engaging member. The rod 6 is forcibly lowered downward by the guide of the slide guide 51 by pressing and engaging 62 and receiving the horizontal pressing force. The lower end presses the lower frame 12, in this example, the upper surface of one of the opposing pieces arranged in the opposite direction to the upper end of the lower frame 12, and the other vertical rod 21 is locked to the lower frame 12. At this time, the pressing protrusion 32 of the protruding member 3 advances in the horizontal direction, so that the locking recess 34 disposed on the upper side of the pressing member 32 and the locking protrusion of the locking member 42 installed on the other vertical rod 21 As a result, the locking recess 34 disposed on the lower side of the pressing protrusion 32 is elastically locked in the same manner as the locking protrusion disposed on the connecting portion 65 at the lower end of the inclined guide groove of the engaging member 62. , The two vertical rods 21 are integrated in the shape of a palm, and the pair of panels 2 are integrated by the connecting function of the projecting member 3, and the pair of panels 2 are lowered by locking the lower frame 12 of the other vertical rod 21. Locked to the frame 12. The lower frame lock member 69 of the lock member 5 receives an urging force due to the compression spring 67 interposed between the lock member 5 and elastically presses against the lower frame 12 to lock the lock. The cushioning member 7 is provided at the lower end of the lower frame locking member 69 so that the elastic pressure contact with the lower frame 12 can be buffered and no noise, damage to the lower frame, or the like occurs during locking. It is like that.

  On the other hand, if the distance between the facets of the pair of locked panels 2 is increased in the distance direction so as to be separated by the fingertips, the projecting member 3 is retracted, and the locking is achieved. The locking of the recess 34 is released and the pressing force against the lock member 5 is released, and the lock member 5 starts to rise due to the biasing force of the spring 56 accumulated when the lock member 5 is lowered by the protruding member 3. , The pressing portion 33 of the projecting member 3 automatically rises so as to slide downward in the inclined guide groove in the opposite direction to the above, and returns to the home position of the other vertical rod 21, thereby the lock member The lock on the lower frame 12 by 5 is released. Therefore, after the lock is released, the folding of the pair of panels 2 and the locking device B are not linked. Therefore, if any one of the vertical rods 21 is moved in the longitudinal direction of the upper and lower frames 11 and 12, a pair of The panel 2 can be extended and the folding door A can be closed.
