る。 The folding door connecting device shown in FIG. 1 is an embodiment of the present invention, in which both side edges of a member 1 having a U-shaped cross section are bent inward, and pivot shafts 2 each having a circular cross section are provided at the ends thereof. A connecting device 3 is formed, and between both pivot shaft portions 2 of the connecting device 3, a pair of pivot receiving pieces 5 protruding from the side ends of the mutually connected door panels 4 are inserted. ,
Both pivot support pieces 5 are rotatably fitted around both pivot shafts 2 so that when both door panels 4 are folded, the outer circumferential surface 6 of both pivot support pieces 5 is The wall thickness of the pivot support piece 5 is changed so that it can abut with maximum pressure. The connector 3 is an aluminum extrusion molded product, and the pivot support piece 5 is also an aluminum extrusion molded product fixed to the side end of the wooden door panel 4 and protrudingly provided. door panel 4
As shown in FIG. 2, they are foldably connected in pairs by a connector 3, and suspended in an opening frame 7 as a bifold door so as to be openable and closable. The pivot support piece 5 is formed in a tapered shape so that the wall thickness gradually increases from part a to part b, and when both door panels 4 are folded, the part b comes into contact with the part b.
The part has the maximum thickness. Therefore, in the folding door connecting device, while the connected door panels 4 are being extended and opened/closed, both pivot receiving pieces 5
The outer circumferential surfaces 6 of the connectors are in contact with each other, and the elastic force of the connector 3, which has a substantially U-shaped cross section, is applied to press against the connector 3, so that there is an appropriate opening/closing resistance at the connector 3. The opening/closing resistance gradually changes so that it becomes maximum when the door panel 4 is folded and opened, so that the door panel 4 is smoothly extended and opened and closed, and when the door panels 4 are folded and abutted against each other. The impact is alleviated. Furthermore, in the folding door connecting device, as shown in FIG. Since the piece 5 is formed to be partially thin, when the door panel 4 is extended and closed, the opening/closing resistance is eliminated, and the door panel 4 is bent in reaction to the extended and closed force. It can be reliably extended and closed without any bending.

枚折り畳み式扉に使用されても良いものである。 In addition, in the folding door connecting device of the present invention, as in the embodiment shown in FIGS. 4 and 5, there is a pivot receiving piece whose outer circumferential surface 6 comes into contact when both door panels 4 are folded. 5 may be partially thickened, and the pivot shaft portion 2 may be formed into a hollow cylindrical shape in order to increase the elastic force of the connector 3 that attempts to clamp both pivot support pieces 5. Alternatively, the connector 3 may be a synthetic resin extrusion molded product, the pivot support piece 5 may be integrally protruded from the side end of the door panel 4, or the connector 3 may be made of a synthetic resin extrusion. It may also be used in a multi-panel folding door in which the panels 4 are connected by connectors 3.

上述の如く、本考案の折り畳み扉の連結装置に
おいては、両扉パネルが折り畳まれた際に、両枢
支受片の外円周面が当接して生じる開閉抵抗が最
大になるので、扉パネルが折り畳まれ相互に当接
する際の衝撃が緩和されるものである。 As mentioned above, in the folding door connecting device of the present invention, when both door panels are folded, the opening/closing resistance generated by the contact between the outer circumferential surfaces of both pivot support pieces is maximized. This reduces the impact when the two are folded and come into contact with each other.
