And a long hole 129 formed at the center of the operating plate 127 constituting the stopper body 128 to prevent movement in the inner and outer directions regardless of the hinge shaft 119 penetrated.

The spring holder 131 may be interposed between the center of the inner end of the operation plate 127 and the slider 104 facing the center of the operation plate 127 so as to interpose an operation spring 130 for maintaining the operator 121 in an operation (stop state) at all times. To form.

By forming a stopper 132 which is bent in the direction of the support bar and protrudes above the inner end of the operating plate 127 to engage with the stop groove 133 formed in the upper end (door direction) of the support bar 106. The lowered support bar 106 is configured to prevent the natural rise.

Looking at the operation relationship of the open support device 100 for a door to which the technology of the present invention is applied as described above is as follows.

When engaging the slider 104 and the fixed base 102 constituting the open support device 100, the fixed surface of the slider 104 in the insertion hole 113 of the lower end of the rail 103 formed in the fixed base 102 (111) After the retaining guide 112 is formed by inserting the lower side of the retaining guide 112 to maintain the fitted state of both ends of the rail 103, the restrictor is coupled in the inner direction of the fixed base 102 ( 114 is engaged with the fixed surface 111 of the slider 104.

That is, the friction pad 117 constituting the restrictor 114 is positioned between the slider 104 and the rail 103, and the fixing plate 118 is connected to the inside of the friction pad 117. Tightening the fixing hole 116 and firmly it is possible to limit the movement of the slider 104, if you want to adjust the height, height loosen the fixing means 115 to adjust the slider 104 up and down Tighten after.

In addition, when the initial state of the support bar 106 is rotated above the slider 104 and viewed in an elevated state, the support bar 106 can maintain the raised state of the slider 104 and the support bar ( This is because the torsion spring 122 constituting the returner 120 interposed on one side of the hinge shaft 119 holding the 106 is pushing the support bar 106 upward.

Of course, in this case, the stopper 132 constituting the operator 121 is retracted (moved in the door direction) so as to be out of the stop groove 133 formed at the upper end of the support bar 106.

In this state, in order to keep the door open, the door is opened as necessary, and then the raised support bar 106 is rotated downward by using the foot pad 105 coupled to the bottom of the support bar 106. Should be in contact with the floor.

That is, when the support bar 106 is rotated, the operator 121 is pushed in the outward direction (the support bar direction in the door) by the force pushed by the operating spring 130, the support bar in the operating plate 127 The stopper 132 bent in the direction is in contact with the upper end surface of the support bar 106 and is engaged with the stop groove 133 that meets the stopper 132 when the rotation of the support bar 106 is completed. Therefore, the support bar 106 rotated downward is prevented from rotating upward by natural factors.

At this time, it is natural that the torsion spring 122 constituting the returner 120 is in a state in which the winding state is compressed to store the reaction force for raising and raising the support bar 106.

When the user wants to close the door while supporting the open state of the door in this way, the user pushes the footrest 126 of the operator 121 constituting the return means 110 so that the support bar 106 stops. It rotates upward by the reaction force of the national spring 122. As shown in FIG.

Looking at this, when the footing 126 is pressed, the operation plate 127 connected to the footing 126 is moved inward (door direction), so that the stopper that is engaged with the stop groove 133 of the support bar 106 ( 132 is out of the stop groove 133, and at the same time the support bar 106 is to be returned by the force pushed by the torsion spring (122).

When the user steps on the footrest 126 of the operator 121, the interference of the hinge shaft 119 is formed by forming the long hole 129 at a position through which the hinge shaft 119 penetrates the center of the operating plate 127. It is possible to operate without being affected.

The present invention is to lower the open support device mounted on the bottom of the door in order to maintain the open state of the door, without the inconvenience or hassle that the user must lift by using the hands or feet to raise the lowered support bar Since it can be easily raised and returned by one touch, the invention has the advantage of providing convenience of use while increasing the quality of the open support device.
