[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a runner that can be applied to folding doors and sliding doors, and in particular, a runner that can simplify attachment / detachment of the runner to / from the door panel.
[0002]
[Prior art]
This type of runner is known, for example, from Utility Model Registration No. 2607366. As shown in FIG. 15, the runner there is inserted into the runner body 61 guided by the guide rail 60, the holding case 63 embedded and fixed in the upper corner of the door panel 62, and the holding case 63 from the lateral outer side. It comprises a runner base 64 to be loaded, a runner shaft 65 that connects the runner body 61 and the runner base 64 up and down, and the like.
[0003]
The holding case 63 has a lock groove 67 for engaging and capturing the lock arm 66, and an engagement guide surface 68 is formed at the entrance thereof. The lock arm 66 is formed of an L-shaped plastic molded product in which a pair of front and rear arms 70 each having a lock claw 69 at the tip and a lever 71 for unlocking both arms 70 are integrally formed. It can be swung around the pivotally supported pin 72. In order to maintain the engagement state of the lock arm 70, a spring 73 and a slide piece 74 are incorporated in the runner base 64, and the lock arm 66 is oscillated and biased to the engagement posture by both 73 and 74. .
[0004]
According to the above-described runner, when the runner base 64 is inserted into the holding case 63 and attached, the lock claw 69 of the lock arm 66 gets over the engagement guide surface 68 and falls into the lock groove 67 to be engaged. Can be installed with a single touch. By swinging the lever 71 of the lock arm 66 in the direction of the arrow against the urging force of the spring 73, the engagement state between the lock claw 69 and the lock groove 67 is released, and the runner base 64 is held by the holding case 63. Can be removed from.
[0005]
[Problems to be solved by the invention]
When the runner base 64 is separated from the door panel 62, the door panel 62 is supported to reduce the weight acting on the runner base 64, the lock arm 66 is held in the unlocked state, and the runner base 64 is held in the holding case. 63 must be pulled out in parallel. In other words, it is necessary to simultaneously perform the operation of supporting the door panel 62, the operation of unlocking the lock arm 66, and the operation of extracting the runner base 64 from the holding case 63, which takes time to separate the runner. . In particular, when the work is performed by only one worker, the door panel 62 is glazed and the runner base 64 is easily caught on the holding case 63.
[0006]
In addition, until the lock claw 69 gets over the lock groove 67, it is necessary to keep the lock arm 66 in the unlocked state. In many cases, the lock claw 69 is pushed back into the lock groove 67, and in any case, the removal work of the runner base 64 is troublesome. When the lever 71 is tilted by placing the fingertip on the upper end of the lock arm 66, the fingertip is difficult to enter depending on the hanging height of the door panel 62, and there is room for improvement in that the lever 71 is difficult to operate.
[0007]
In a state where the runner base 64 is mounted on the holding case 63, the runner base 64 and the holding case 63 are positioned in the vertical direction by the stepped portion 75 provided on the lower peripheral surface of the runner base 64. If there is even a slight gap between the bottom surface of the mounting hole 76 of 62 and the bottom of the runner base 64, the runner base 64 can move up and down relative to this gap. Therefore, when an upward external force is applied to the door panel 62 or a downward external force is applied to the runner base 64, both the upper and lower parts 62 and 64 are prevented from rattling up and down. For example, every time the door panel 62 is opened and closed, noise is generated, and the peripheral surface of the runner base 64 may be worn with the rattling operation.
[0008]
The object of the present invention is to easily remove the runner base while following the features of the conventional runner, that is, easy assembly to the door panel, so that the door panel can be suspended and separated at the construction site. It is to provide a runner that can be done with less effort. The object of the present invention is to prevent the runner base from rattling in the vertical direction as well as in the front / rear / left / right direction when the runner is mounted on the door panel. The object is to provide a runner that can eliminate open / close noise.
