Description

[Detailed Description of the Invention] This invention relates to a door roller and aims to provide a door roller that can easily deal with variations in the spacing in the lower mounting recess of a sliding door or the like to which the door roller is attached.

Regarding the door rollers used in conventional sliding doors, etc.
A spring-shaped hanging plate was used in the mounting recess at the bottom of the sliding door so that it could be mounted without using screws.

However, in the case of conventional products, if the spacing between the mounting recesses at the bottom of the sliding door is constant, there is not much of a problem. is difficult to use.

For this reason, some methods have been used to deal with this by widening the degree of overlapping of the hanging plates at the upper end of the door roller where the upper ends of the spring-like hanging plates are overlapped (for example, Utility Model Publication No. 51-9791).
(Implementation shown in Fig. 3), each adjustment at the top of the door roller had to be done by removing the door roller from the recess at the bottom of the sliding door, which was extremely troublesome, and the adjustment range was only narrow.

Therefore, this invention was devised to eliminate the above-mentioned drawbacks and inconveniences of the conventional methods.The structure is such that the holding body for the military has an opening on the side, and a screw shaft and a screw shaft inside. Equipped with a slider that can be moved up and down by rotational adjustment, spring-like hanging plates are provided on both sides of the outside of the holding body, and the upper ends are attached to the upper part of the holding body. The invention is characterized in that a protrusion is formed in the opening, and the spacing between the protrusions can be adjusted by a slider to adjust the degree of opening of the hanging plates on both sides.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

10 is a frame-shaped holder; 20 is a car support plate 21 and a car 2
Military part consisting of 2 and 30.30' shows a spring-like hanging plate.

A military part 20 is attached to the holding body 10, and the position corresponding to the car 22 in the holding body 10 is open at the bottom, and the position of the car 22 is determined by providing a support plate 21 so as to be pivotable. The position can be adjusted up and down.

In addition, the upper portions of both sides of the holding body 10 are formed as winding portions 11 and 11' facing each other, and the screw shaft 40 is installed inside the holding body 10 in such a way that it can freely rotate but not fall out. The head 41, which is the adjustment side of the screw shaft 40, is placed on the lower side.

Reference numeral 12 denotes an auxiliary mounting plate that regulates the vertical movement of the screw shaft 40 between the lower part of the holder and restricts the rotational movement of the screw shaft 40 so that it can only rotate idly.

Further, a slider 50 is screwed onto the screw shaft 40, and the slider 50 is mounted inside the holder 10 so that it can be moved up and down without rotating when the screw shaft 40 rotates. An aperture 13.13' is provided on the side.

The above-mentioned hanging plates 30, 30' are attached by winding 31.31' with the upper parts of both sides along the winding part 11.11' of the holder]0 so that the elastic action can be performed without difficulty. The winding portions 31 and 31' are respectively designed to function as spring-like bodies, and both sides have protrusions that enter the openings 13 and 13' of the holding body 10. 33.33', and this protrusion 33.33'
When the slider 50 moves up and down, it comes into contact with the protrusions 33 and 33', so that the distance between the protrusions 33 and 33' can be expanded and adjusted by the slider 50.

Therefore, as the slider 50 rises due to the rotation of the screw shaft 40, the distance between the protrusions 33, 33' is expanded, so that the degree of opening of the hanging plate 30, 30' can be adjusted.

In the figure, reference numeral 14 denotes an adjustment-side opening provided in a part of the holder 10 at a position corresponding to the head 41 of the screw shaft 40, into which at least a screwdriver or the like can enter for adjustment.

Reference numeral 34.34' denotes a hook portion formed by bending the lower end of the hanging plate 30.30' into a curved shape as shown in the figure.
34' is designed to hold the lower stile a of the sliding door A, etc., and solves the problem of the lower stile a easily slipping off if it simply touches the lower stile a.

Furthermore, 35° 35' is a small protruding part in which a suitable part of the hanging plate 30, 30' is made to protrude to the outside, so that it can be more stabilized when attached to the mounting recess C of a sliding door A, etc. ing.

This device is constructed as described above, and when the spring-shaped hanging plate 30, 30' whose upper end is attached to the upper part of the holder 10 is pushed into the mounting recess C of a door wheel, etc., the spring-shaped hanging plate 30. The mounted state set in the mounting recess C can be easily maintained with the push-open force of 30, 30'.

According to this invention, even when installing a door roller for a sliding door whose specifications are different and the distance between the mounting recesses C is widened as shown in Figs. 4 and 5, the screw shaft 40 can be inserted from below Adjust the slider 50 to raise it and lower the hanging plate 30.
This problem can be easily solved by simply expanding the distance between the protrusions 33 and 33' of 30'.

Therefore, the mounting condition can be adapted to the spacing of the mounting recesses C of sliding doors etc. that vary in size with a very simple adjustment, and it can also be adapted to variations due to dimensional errors of the recesses. It becomes easier to do.

Moreover, since the adjustment can be made from below the door roller, there is no need to remove the door roller from the recess C and adjust it each time.You can adjust the door roller while it is inside the recess C, which greatly improves work efficiency, and compared to the conventional method. Compared to conventional products, it has excellent effects not found in conventional products, such as being able to easily perform adjustments over a wide range.
