Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stopping device for a sliding door, and more particularly to a stopping device for a sliding door that can be opened and closed easily, has a low impact noise with a pillar, and can be closed without forming a gap with the pillar. It is a thing.

[0002]

[Prior art]

 Conventionally, this type of sliding door has been designed so that it can slide by being fitted between the opposing grooves of a wooden sill and a kamoi, which have relatively poor sliding properties. The occurrence of gaps due to bounces from the door was overlooked, and attention was paid to the improvement of sills and sliding doors solely for improving the sliding property of sliding doors.

[0003]

[Problems to be solved by the device]

 As a result, in recent years, improvements have been made to the rails of sills and door rollers of sliding doors, and the ones that can be opened and closed with extremely small force have been developed. Although there have been demands for countermeasures against impact noise and the generation of gaps due to bounces from pillars, the current situation is that these demands are not yet satisfied.

The present invention was devised to eliminate the above-mentioned drawbacks of conventional products. In a sliding door having excellent lubricity, the molding and mounting to the sliding door are simplified, and the pillars generated when the sliding door is opened and closed. The object of the present invention is to provide a sliding door stop device that has a low impact sound, does not generate a gap due to bounce from the pillar, and can easily open and close the sliding door.

[0005]

[Means for Solving the Problems]

 The present invention has been devised in view of the above, and is provided on one end side of a stopper main body made of a horizontal strip having elastic and restoring force, such as a synthetic resin strip or a stainless steel strip, below the stopper main body. By bending toward the end, the base end side is formed into a straight or curved steep surface having a height of about 3 to 10 mm to form a curved portion having a cross-sectional spawn shape in which the free end side is a gentle slope, The sliding door stop device is characterized in that a horizontal end is provided with a screw fixing hole.

A double-sided adhesive tape is attached to the upper surface of the other end side horizontal piece of the stopper body in order to facilitate the attachment to the groove portion of the Kamoi located at a relatively high place during construction.

[0007] Also, as the stopper body, an injection molded product made of a synthetic resin having elasticity and restoring force such as polypropylene or polycarbonate is generally used, but a press molded product made of a stainless steel strip is used. Can be used.

[0008] Further, the free end portion of the curved portion is formed with an abutting piece that abuts the groove portion of the duck and slides in the groove portion when the curved portion is pressed by the upper rail of the sliding door. .

Further, as the steep slope located on the base end side of the curved portion, the center point is on the extension line of the other end side horizontal piece, and a locus drawn with an arc having a radius of curvature of about 15 to 25 mm. It is formed by a curved line with a height of about 3 to 10 mm that hangs downwards or a straight line with a height of about 3 to 10 mm that inclines at a gradient of 50 to 80 degrees, while the free end side of the curved portion is formed. The gentle slope located at is formed so that the entire curved portion has a spoon-shaped cross section with a saucer-shaped curve drawn with a relatively large radius of curvature compared to the radius of curvature of the above-mentioned steep slope. The reason why the height of the steep slope is about 3 to 10 mm is that when the height is about 3 mm or less, the frictional resistance when the sliding door is closed is small, while when the height is about 10 mm or more, conversely. Since the abrasion resistance is too large, the desired effect cannot be obtained.

On the other hand, at the time of construction, first, using a double-sided adhesive tape adhered to the upper surface of the other end side horizontal piece of the stopper body, temporarily fix it near the pillar of the groove of the Kamoi, and then It is attached by screwing it using a screw hole formed in the horizontal piece on the end side and then fitting a sliding door in the groove of the above-mentioned Kamoi.

[0011]

[Action]

 The device for stopping a sliding door of the present invention comprises a stopper body composed of a horizontal strip plate having elasticity and restoring force, such as a synthetic resin strip plate or a stainless steel strip plate, which is bent toward the lower side of the stopper body at one end side thereof. Depending on the composition, the base end side has a straight or curved steep surface with a height of about 3 to 10 mm to form a curved portion having a spoon-shaped cross section with the free end side having a gentle slope and the other end side horizontal piece of the stopper body. Since a screw hole is formed on the stopper body and a double-sided adhesive tape is attached to the upper surface of the horizontal piece on the other end side of the stopper body, the stopper body is attached to the Kamoi groove by the double-sided adhesive tape. It is temporarily fixed near the pillar and fixed with screws using the screw holes.

Further, after the installation, when the sliding door is closed, the upper cross section of the sliding door, which moves, strikes from a direction substantially perpendicular to the steep slope provided on the base end side of the curved portion, and a large resistance is exerted. It presses this while receiving it, then rides on a gentle slope provided on the free end side of the curved part and stops, and the frictional resistance generated by these two-step pressing completely saves the movement. When opening the sliding door, there is no near-right angle to the steep slope that was used when closing the door, and only a slight pressure is applied from the gentle bend of the gentle slope, so it can be opened with a light force. As described above, the sliding door stopping device according to the present invention smoothly opens and closes because the pressing force applied to the sliding door when opening and closing is different in two steps when closing and one step when opening. .
