Is designed to be substantially the same as or slightly larger than the groove width. Therefore, when the door neck portion 11 is inserted into the Kamoi groove, the balls 15, 15 are immersed in contact with the inner surface of the Kamoi groove, so that there is no hindrance to the operation of inserting the door neck portion 11.
After the construction, the balls 15, 15 return to the normal state of FIG. 2 by spring bias and protrude outward, and come into close contact with the inner surface of the Kamoi groove (FIG. 1). Will not occur.

FIGS. 4 and 5 show another embodiment of the present invention, in which a door neck fitting 20 having projections 21 and 22 at the upper end of a sliding door 10 is fixed with screws 23 and 23. FIG. FIG. 4 shows an example in which the door neck 11 protruding from the upper end of the sliding door 10 is partially cut off, and a door neck fitting 20 having substantially the same width and the same height as the door neck 11 is fixed to the cut portion. However, the door neck 11 may not be protruded, and only the door neck fitting 20 fixed to the upper end of the sliding door 10 may be inserted into the Kamoi groove 2 or the Kamoi rail 3. In this case, the short toe member 20 can be attached to an arbitrary position at the upper end of the sliding door 10, but it is preferable to attach to the end of both doors, so that the toe member 2 to be inserted into the Kamoi groove 2 or the Kamoi rail 3.
Through 0, the mounting state and running of the sliding door 10 are stabilized.

The protruding portions 21 and 22 are resiliently urged outward from the front and back surfaces of the door neck fitting 20, respectively. The configuration of the pair of protruding portions 21 and 22 is the same and is provided symmetrically. Therefore, the configuration and operation of one of the protrusions 21 will be described below.

At the base end of the protruding portion 21, a retaining portion 25 is provided which is accommodated in a retaining receiver 24 formed on the side opposite to the door neck fitting 20, and at the center portion, the door neck fitting 20 is provided. A spring stopper 27 accommodated in a spring stopper 26 formed substantially at the center in the width direction is provided. A spring 28 is mounted between the retaining portion 25 and the spring retaining portion 27. Projection 2
1 is housed in a tip receiver 29 which is recessed on the surface of the door neck fitting 20.

Thus, the protruding portion 21 is constantly urged by the spring 28 so as to protrude outward from the surface of the door neck fitting 20, and protrudes outward from the surface as shown in FIGS. However, when an external force exceeding the urging force of the spring 28 is applied, the protruding portion 21 is buried and housed in the tip receiver 29. Therefore, while making the door neck (door neck fitting) narrower than the Kamoi groove, it is easy to attach the sliding door to the frame,
After the attachment, the projections 21 and 22 project outward and are elastically engaged with the inner surface of the Kamoi groove.
It is possible to prevent rattling.

The protruding portions 21 and 22 are not limited to the disk shape shown in the figure, but may be any shape such as a square shape, but the side surfaces thereof are preferably tapered or curved. Thus, when the door neck 11 and the door neck fitting 20 are fitted into the ditch groove in a state where the sliding door 10 is inclined, the protrusions 21 and 21 are provided.
The side surface of the door 2 does not come into contact with the corner of the ditch and is not caught, so that the operation of attaching the sliding door is further facilitated. In addition,
In FIG. 5, reference numerals 30, 30 are insertion holes for the screws 23, 23.

The door neck 11 (or the door metal fitting 20)
Is not limited to the shape shown in the above-described embodiment, and may be a convex shape as shown in FIG. FIG.
The sliding door 10 is formed to have substantially the same thickness up to the upper part as shown in FIG.
The upper end portion to be inserted into the Kamoi groove 2 or the Kamoi rail 3 may be the door neck portion 11. In any case, the upper end portion of the sliding door 10 to be inserted into the Kamoi groove 2 or the Kamoi rail 3 becomes a door neck portion, and protrudes outwardly from at least one of the front and back surfaces as in the above-described embodiment. A part 12 (FIG. 1) is provided.

The door neck 11 (or the door neck fitting 20)
The mohair can be stuck or adhered to the surface that engages with the inner side surface of the Kamoi groove 2 (or the Kamoi rail 3) over the entire length direction or divided at arbitrary plural points. Mohair is a fiber planted on a substrate,
Since the surface is raised and has elasticity, it is elastically engaged with the inner side surface of the ditch and contributes to smooth sliding door traveling. A soft synthetic resin may be used instead of mohair, or the door neck 11 itself may be formed of an elastic body such as a soft synthetic resin.

A stopper 32 as shown in FIG. The stopper 32 is formed by inclining upwardly inwardly inclined triangular portions 34, 34 of a plate-like body made of a metal material or a resin material at an acute angle upward to form a substantially U-shaped cross section. The shaped side plate portions 34, 34 each have a steeply inclined side 35 and a gentlely inclined side 36.

When such a stopper 32 is fitted into the end of the mouth of the Kamoi groove 2 and fixed with screws 37 through screw holes 33 (FIG. 9), when the sliding door 10 is closed, the front and back surfaces of the door neck are used. The projecting portion urged outwardly (the ball 1 of the embodiment shown in FIGS. 2 and 3 in FIGS. 9 to 11)
5) is the gentle slope 3 of the stopper 32.
6 and is gradually pushed in against the elastic force (FIG. 10). As a result, resistance is given to the traveling of the sliding door 10, and the sliding door 10 is decelerated. Then, when the protruding portion or the ball 15 exceeds the vertex of the triangular side plate portion 34, the tip of the sliding door 10 hits the vertical frame 8 of the opening four-sided frame and stops (FIG. 11). In this state, the protruding portion is locked to the steeply inclined side 35 of the stopper 32, so that the front end of the sliding door 10 is prevented from bouncing back after colliding with the vertical frame 8, and holding the sliding door 10 in the closed position. Can be.

The side plate portion 34 of the stopper with which the protruding portion abuts may be configured to be elastically deformable like a leaf spring.

As described with respect to the above-described embodiment, the width L of the door neck including the projection (FIG. 3) is determined when the projection is in the maximum projection state from the front and back surfaces of the door neck (normal state). It is preferable that the groove width of the Kamoi groove or the Kamoi rail into which the door neck portion is inserted is designed to be substantially the same as or slightly larger than the groove width of the Kamoi groove, but the groove width of the Kamoi groove or the Kamoi rail into which the door neck portion is inserted becomes larger. A clearance may be provided as described above. In this case, the clearance is preferably in the range of 0 to 1.0 mm. If the clearance is more than that, the sliding door rattles in the groove.

[0028]

According to the sliding door of the present invention, a protruding portion is provided on the front and back surfaces of the door neck so that the sliding door can be inclined and the door neck can be easily inserted into the ditch groove. Since the protruding portion protrudes outward and comes into contact with the side surface of the Kamoi groove, it is possible to prevent rattling of the sliding door.

Further, by using a stopper fixed to the end of the groove into which the door neck of the sliding door is inserted, the running speed of the sliding door is reduced when the sliding door is closed, and the tip of the sliding door collides with the vertical frame. It is easy to hold the sliding door at the proper closing position by preventing the sliding door from rebounding.
