Description

The present invention relates to a multi-series adjusting door roller having a wheel height adjusting means used for a pull-type fitting.

In recent years, in pull-type sash windows, the weight is large due to the adoption of double glazing with air or gas sealed between the glasses in order to improve heat insulation performance and prevent dew condensation, and the increase in size of the window itself. Shoji are becoming widespread. A large load capacity is required for a door roller used for such a heavy shoji, but if the wheel itself is enlarged or a double door roller is further connected with a connecting member to improve the load capacity, Since the door roller itself becomes bulky in the height direction and the width direction, the design of the shoji is greatly reduced.

On the other hand, there is also a multi-unit type door roller in which the number of wheels is increased to improve the load capacity of the door roller (see, for example, Patent Documents 1 and 2). Here, in the interlocking door wheel for sash described in Patent Document 1, the magnet body is divided into an upper chamber portion and a lower chamber portion, five spherical door wheels are provided in the lower chamber portion, and a height adjusting device is provided in the upper chamber portion. In the door roller described in Patent Document 2, three wheels are provided on a wheel support, and the wheel support is supported by the door roller main body.

However, the sash interlocking door roller described in Patent Document 1 is bulky in the height direction because it is necessary to provide an upper chamber portion and a lower chamber portion, and it is necessary to partially form a part by a magnet. Therefore, it is disadvantageous as a product in terms of manufacturing cost and strength.

Further, the door roller described in Patent Document 2 is configured by assembling one wheel support having three wheels to a door roller main body having three contact engaging surfaces corresponding to each wheel. Therefore, there is a limit to the weight of the shoji that can be handled. Here, in general, the door roller has a limitation on the one with a large weight of the shoji from the viewpoint of load capacity, and even if the weight is small, the operability is affected by the inertial force at the time of opening and closing the shoji. There are restrictions from the point of view. For this reason, in such a door roller, it is often necessary to design and manufacture a wide variety of shoji that are generally used according to the shoji, and there are problems in terms of manufacturing cost and product management. ..
