があった。(Prior Art and Its Problems) Conventionally, a so-called V-groove door rail having a shape as shown in FIG. 3, that is, a V-shaped groove a in which a wheel b of a door roller rolls is formed on an upper surface of a rail body a. However, this is because the rolling wheel rolls with a part of both side surfaces of the door wheel b sandwiched by both side walls of the groove a ', and therefore the sliding door does not swing to the left and right and travels on the rail in a stable state. With the advantage of being able to do so, it is becoming widely used, but in the case of this rail,
Large lateral pressure on the sliding door, for example, when a child is playing and hits the sliding door, the shape of the groove a'is V-shaped, that is, on the left,
Since the tapered surface is such that it spreads to the upper right, the wheel b is pushed up against the dead weight of the sliding door by the action of the tapered surface, slips out of the groove a'as shown by the chain double-dashed line, and derails. There was a risk of an accident where the car would tilt and fall.

のである。(Invented Configuration) derailing prevention apparatus according to the present invention, in the V-type door roller rails having grooves 1 1 of a wheel 2 of door rollers on the upper surface of the rail body 1 rolls, upper sides of the grooves 1 1 Inward engaging claws 1 2 ,
1 and 2 are integrally formed over the entire length of the rail body 1 in the longitudinal direction,
And it is characterized in structure formed by circumferentially provided with engaging claws 2 1, 2 1, engaging claws 1 2, 1 2 are fitted discontinuously on both sides of the wheel 2.

Part of both side surfaces respectively contact the side walls of the groove 1 1, since the rolling while being sandwiched between the side walls, the sliding door travels on the rail in a stable state without swinging to the left and right.

ある。Thus, in the stable state shown in FIG. 1, when a large lateral pressure acts on the sliding door, for example, when a large force acts on the sliding door, the wheel 2 moves to the left or right by moving the sliding door to the left or right. 1 by the action of the tapered surface of the first sidewall pushed against the own weight of the sliding door, is about to be pushed out from the groove 1 1, wheel engaging claw 1 2 inward formed on the upper end of the groove 1 1 some of circumferentially provided by the engagement claws 2 1 to 2 sides second
Because engaging locked as shown in FIG, prevents further increase of the wheel 2, in which falling That derailing from the groove 1 1 is prevented, if there are no lateral pressure, the wheel 2 are those returned to a stable state of FIG. 1 depressed to the deepest part of the groove 1 1 by the weight of the sliding doors, rolling in a stable state.

とができるに至ったものである。(Effects of the Invention) As described above, according to the wheel slip prevention device for a door rail of the present invention, inward engagement pawls are formed on both sides of the upper end of the V groove in the door rail of the V groove. Since the engaging claws that engage with the engaging claws are discontinuously provided around both sides of the door wheel, even if a large side pressure is applied to the sliding door, such as when a child hits the body, As in the case of the V-groove door rail, the sliding door is lifted up, the wheels of the door roller will not slip out of the rail groove, and the sliding door will not fall over. Therefore, a highly safe V-groove door rail is provided. It is something that has become possible.
尚、車輪両側面に周設される係合爪は同心円的に複数列
に形成しておけば、いずれかの列の係合爪にレール本体
の係合爪に係合することになり、より安全性が確保され
る。If the engaging claws provided on both side surfaces of the wheel are concentrically formed in a plurality of rows, the engaging claws of either row will be engaged with the engaging claws of the rail body. Safety is secured.
