Description

[Detailed description of the invention] This invention has a shaft bearing part that pivotally supports the hanging door of the folding door, and a shaft bearing of the hand door that is press-fitted into the lower part of the upper frame member of the constructed frame and supports the specific shaft of the hand door when the folding door is bent. The door holder has a pressure-fitting holding part that can be used to attach a member to allow the hinged door to rotate freely, and when the door is folded.
This invention relates to a folding door sash that is convenient for use and construction, and allows for the locking of a hand door.An example of the folding door sash is described below with reference to the drawings.

In the figure, A is a metal frame formed into a gate shape, and a pair of vertical frame members 2, 2 are brought into contact with both left and right ends of the upper azusa material 1 with a roughly H-shaped cross section, and the joints are integrally screwed together. It is formed into a gate shape.

Reference numeral 3 denotes an underframe member having a trapezoidal cross section that supports the frame A, and a support screw 4 screwed onto the lower ends of the vertical frame members 2, 2 of the frame A to enable height adjustment of the frame A. ,4 is supported.

5 is a folding door that is built into the frame A so that it can be bent freely, and a pair of short roots 8 and 9 are placed on both the left and right ends of the upper and lower frames 6 and 7 to form a rectangular door frame. At least one or more doors 11 and 11' each having a mesh 10 stretched on the inside are butted against each other and are each attached with a hinge 12, so that they can be extended and bent.

Reference numeral 13 denotes a door holder attached to the lower part of the upper Azusa material 1 in the frame A, which has semicircular arc-shaped recesses 14 and 15, large at one end and small at the middle, and an elastic piece 16 at the other end. From the elastic piece 16.16, two members 11 having an arcuate recess 17 and a shaft bearing 18 are connected correspondingly to each other, and the shaft bearing 18 is provided on one side, and the other side is opened in the direction in which the folding door 5 is extended. A press-fit holding part 19 is formed, and when installed, it is fitted from within the running groove edge 21 of the hanging wheel 20 of the folding door 5 formed at the lower part of the upper Azusa material 1, and inserted into the small diameter hole 22 in the middle part. It is fixed with screws 23.

Reference numeral 24 denotes a support shaft protruding from the upper end of the fishing door 11 of the folding door 5, which is supported via the hanging wheel 20 to the running groove edge 21 of the upper Azusa material 1, and whose upper portion is inserted into the shaft bearing portion 18. The lower part is inserted into the shaft support member 26, which is made up of three pieces that are fixed to the short roots 9 of the door 11 with fitting screws 25.

Reference numeral 27 is a ratio shaft provided at the uppermost end of the hand door 11' of the folding door 5, which also serves as a mounting shaft for the hanging wheel 20 of the door 11', and corresponds to the inside of the running groove edge 21 of the upper Azusa material 1. When the door 5 is folded, the door holder is fitted into the press-fitting holding portion 19 of the member 13, and the door 5 is folded.
to prevent natural rotation.

Reference numeral 28 denotes a lower support device for the fishing door 11, in which a shaft 30 protruding from a cross-sectional mounting plate 29 is loosely fitted onto the short root 9 of the door 11, and the mounting plate 29 is attached to the vertical frame member 2 by the support screws 4. Fix to.

31 is a conventionally known door installed in parallel with the folding door 5.

In the door support member 13 according to the present invention, the press-fitting holding portion 19 may have a semicircular arc shape, as shown in FIG. 8 of the drawings.

Since the folding door sash according to the present invention is constructed as described above, when the frame body A is now formed and the folding door 5 is to be installed in a manner that it can be expanded and folded, first, a pair of sashes are attached to both left and right ends of the upper Azusa material 1. Assemble the gate-shaped frame A by applying the vertical frame materials 2 and 2,
Furthermore, a door holder is provided as a member 13 at the lower part of one side of the upper frame member 1 of this frame A.
After fixing the screws 23 integrally, insert the bendable folding door 5 assembled in advance, and attach the support shaft 24 protruding from the opening door 11 to the door holder member 13. shaft bearing part 18
After fitting into the frame A, the lower part of the fishing head door 11 is rotatably attached by the support device 28, and then the vertical frame member 2.2 in the frame body A is attached.
A folding door is formed by supporting the support screws 4, 4 on the underframe material 3 provided on the floor, and when the folding door 5 built in the frame A is rotated and bent, the folding door 5 door 11'
The ratio shaft 27 protruding from the door holder, which is opened in the direction in which the folding door 5 is extended, fits into the press-fitting holding portion 19 of the member 13 to maintain the folding door 5 in its bent state. To extend the folding door 5 from this state, if you pull the front door 11' of the folding door 5, the three elastic pieces 16.1
The ratio shaft 27 held by the hinge 6 is removed, and the door 11.11' is expanded. At that time, the support shaft 24 of the hanging door 11 is fitted into the shaft bearing 18, so the folding door 5 is held in its frame. It is expanded into body A.

Conventional folding door sashes are made by placing a pair of vertical frame members on both the left and right ends of the upper and lower frame members to form a metal frame, and one or more doors are hinged to each other inside the frame so that it can be bent freely. In this type of folding door, when the hanging door of the folding door is pivoted to the frame, the vertical frame material of the frame and the door frame are Since hinge pieces are formed on each side and the hinge pieces are combined and supported, it is extremely time-consuming to assemble them, and the structure is complex and prone to failure. There was no part to stop the bent door of the folding door, so when the folding door was rotated and folded to one side of the frame, it would naturally expand due to the wind and cause an obstruction to traffic. There were many things that happened.

However, the folding door satsushi according to the present invention has a gate-shaped frame by applying a pair of vertical frame members to both the left and right ends of the upper Azusa wood, and at least two or more doors are made to be flexible inside the frame. In a folding door sash in which a folding door is fitted in such a way that it can be expanded, a pressure-fitting holding part is provided at the bottom of the above-mentioned azusa material, and is made of an elastic piece that has a shaft bearing part on one side and an opening in the direction in which the folding door is extended. The door holder has a member, and the shaft bearing part is arranged on one side of the upper ladder body and is screwed to the member. The door holder is inserted into the front door of the folding door and has a protruding shaft that fits into the pressure-fitting holding part when folding. can be constructed from a single part, and when the folding door is folded, the door can be elastically held, and since the door on the hand side that makes up the folding door is held by the pressure-fitting holding part, the door on the hanging side can be held elastically. Do not collide with

Moreover, when attaching the folding door to the formed frame,
The door support provided on the upper Azusa material can be easily fixed by simply inserting the support shaft of the fishing door into the shaft bearing part of the member, so the installation work is extremely efficient. In addition, since the door support member is provided with a pressure-fitting holding part for locking the hand door, which is made of an elastic piece that opens in the direction in which the folding door is extended, the hand door of the bent folding door is Since it is securely locked by fitting the specific axis into the pressure-fitting holding part, the folding door does not naturally expand when folded, so it prevents obstruction of passage due to expansion due to wind, etc. In addition, the door support serves both as a shaft bearing for the hanging door and as a rotation stopper for the hand door, so it has great practical effects as a folding door sash that is convenient for use and construction.
