Description

  More particularly, the present invention relates to a sliding door for preventing a sliding door such as a sliding door for a sliding window of a house and a building from being lifted upward and detached from the rail. The present invention relates to a stopper device.

  Conventionally, as a sliding door prevention device such as a screen door, it has a rail insertion groove that opens upward at the top, and a roller is located at the lower end of the groove, and it is slidably attached to the upper end of the vertical fence of the sliding door. Various sliding door stoppers having a structure biased upward by a spring have been proposed (see Patent Documents 1 and 2). For example, in Patent Document 1, an attachment body and an upper surface of the attachment body are provided. A rod provided, a pin provided at the tip of the rod, a rod insertion groove opened on the lower surface, a long hole opened in the rod insertion groove, and a notch that is narrower than the diameter of the rod and opens the long hole on the lower surface. A main body having a door wheel supported on the upper part thereof, and a spring provided in the rod insertion groove, and the tip of the rod is inserted into the rod insertion groove of the main body by expanding and deforming the notch with a pin. , Special In Document 2, the main body of the locking device is fitted in the hollow portion of the vertical shaft of the sliding door, and the locking protrusion of the vertical shaft is engaged in the locking recess at the bottom of the main body of the locking device. A rail fitting groove portion into which the upper rail is fitted is provided at the top of the main body of the locking device, and a roller abutting on the lower end of the upper rail is rotatably supported at the bottom of the rail fitting groove portion, and the locking device A spring for urging the main body upward toward the upper rail is attached to the locking device main body, the spring is bent, and one end serving as a support pin penetrating the roller and biasing the locking device main body upward There has been proposed a wire spring that is integrally provided with the other end that is brought into contact with the vertical rod for the purpose of doing so.

In Patent Document 1, the main body is pushed upward and biased by a spring, and the door is in contact with the lower end surface of the upper rail, so that the sliding door can run smoothly, and when the sliding door is lifted upward, the spring is attached. It is possible to prevent lifting by power.
In Patent Document 2, by providing a locking projection, the locking device main body is prevented from popping upward even when biased by a spring, and the locking device falls off before the sliding door is fitted into the rail frame. There is no fear, and the roller support shaft and the spring are integrated so that the number of parts can be reduced.

However, in the sliding door stopper device of Patent Document 1, the position of the sliding door stopper device with respect to the upper rail is adjusted against the biasing force of the spring while being set with a register, but the sliding door stopper is set. Because the stopper itself is attached to the upper part of the sliding door, it is difficult to work, and it is difficult to know the proper position where the stopper function can be demonstrated. The sliding door did not open and close smoothly.
In addition, in the sliding door locking device of Patent Document 2, the roller does not move up and down after the sliding door locking device is attached to the sliding door, and the sliding door cannot be absorbed when the sliding door is distorted or warped. It did not function or the sliding door could not be opened and closed smoothly.

  Therefore, what the present invention intends to solve is that it is easy to mount the sliding door locking device at an appropriate position where the locking function can be exerted, and the mounting workability is improved and the mounted sliding door is detached from the rail. It is in the point which provides the sliding door slip-off prevention apparatus which can open and close smoothly.

  In order to solve the above-described problem, the sliding door locking device according to the present invention is provided with a substantially U-shaped fitting groove having an upper opening into which the upper rail is fitted, and a roller that contacts the lower end of the upper rail is provided on the sliding door surface. A sliding door anti-skid device that uses a main body that is rotatably supported around a vertical horizontal axis on a vertical shaft of a sliding door, wherein the main body is provided with the insertion groove at an upper end portion, and A vertically long stopper part with a long mounting hole formed vertically on the lower side, and the roller is pivotally supported by the upper end part, and is vertically attached to the stopper part when attached to the vertical hook. A roller urging elastic body that is separated into a vertically long roller support portion that is slidably supported in a direction and urges the roller support portion upward with respect to the detachment prevention portion. Provided between The roller support portion and the anti-separation portion are provided with slide restricting means for making the roller support portion non-slidable in the vertical direction with respect to the anti-separation portion at a position relatively separated from the attached state. It is characterized by.

  Here, an elastic body is interposed between the roller support portion and the detachment prevention portion, and the slide support means is separated from the roller support portion and the detachment prevention portion relative to the attached state. By being held at the acting position, the roller support part cannot be slid in the vertical direction with respect to the anti-separation part in a state where it is not attached to the downspout, and the anti-separation part is non-slidable in the attachment state. It is preferable that the roller support portion is slidable in the vertical direction.

  Further, the slide restricting means is provided with two locking protrusions standing symmetrically on the lower side of the elongated hole of the roller support portion and on the side of the locking portion, and sandwiching the locking portion, It is preferable that the locking projection piece is engaged with a concave portion provided on the surface opposite to the roller support portion of the slip-off preventing portion at a position relatively separated from the attached state.

  According to the sliding door locking device according to the present invention, an approximately U-shaped fitting groove having an upper opening into which the upper rail is fitted is provided, and the roller that contacts the lower end of the upper rail is rotated about a horizontal axis perpendicular to the sliding door surface. A sliding door locking device that uses a main body that can be supported by attaching it to a vertical shaft of a sliding door, wherein the main body is mounted on the upper end of the insertion groove and vertically long below the insertion groove.

As shown in FIG. 1, the sliding door locking device 1 according to the present invention includes a coil spring 4 that is a roller biasing elastic body that biases the roller support portion 3 upward against the locking portion 2 and the locking portion 2. A leaf spring 6, which is an elastic body that is interposed between the roller support portion 3 and urges the roller support portion 3 to move away from the anti-separation portion 2, is provided on the roller support portion 3. 6, the locking protrusion 51 at the lower part of the roller support 3 is engaged with the recess 23 of the locking part 2 at a position where the locking part 2 is separated from the roller support 3 relative to the mounting position. The restricting means 5 acts so that the roller support portion 3 cannot be slid in the vertical direction with respect to the anti-separation portion 2. It can slide in the direction.
As a result, the sliding door locking device 1 attached to the vertical fence F as shown in FIG. 2 has the upper rail R inserted into the insertion groove 21 and the roller biased upward by the coil spring 4 that is a roller biasing elastic body. The support 3 absorbs the upper rail warp and the like while sliding in the vertical direction, and the lower end of the upper rail R is always pushed up via the roller 31 to prevent the sliding door from being lifted and bounced at the time of opening and closing, and is removed from the rail frame. This can be surely prevented.

  The stopper part 2 is provided with a fitting groove 21 having an upper opening formed on the upper end portion, which is formed by a substantially flat plate on one side and a flat plate rounded in an arc shape on the other side, and the upper rail R is fitted in the fitting groove 21. This prevents the sliding door D, to which the sliding door locking device 1 is attached, from coming off the rail frame. A long hole 22 longer than the axial width of the assembly screw S is provided in the vertical direction for attaching the sliding door slip-off preventing device 1 to the vertical fence F at a substantially center. Thereby, when attaching to the vertical fence F, the sliding door locking device 1 can be moved in the vertical direction in accordance with the height of the upper rail R to be positioned. Further, at the lower part, the locking protrusion 51 of the roller support portion 3 is engaged so as not to be slidable in the vertical direction at a position where the roller support portion 3 and the anti-separation portion 2 are relatively separated from the attached state. The recess 23 is provided, and the upper ends of the left and right side surfaces of the recess 23 are tapered so that the locking protrusion 51 is easily fitted into the recess 23. A projecting mounting portion 24 having a substantially elliptical column shape that is long in the vertical direction including the long hole 22 is extended on the vertical shaft F side of the long hole 22, and is located at a substantially central portion of the roller support portion 3 in the horizontal direction.
