DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnet guide pin which is suspended and held by a runner on a top rail fixed horizontally upward by a runner so that the sliding door body can freely move in and out by a magnetic force embedded in a floor. The present invention relates to a suspension type sliding door in which a sliding traveling guide is performed by being inserted into a traveling guide groove formed in a lower end surface of a sliding door body in a protruding state.

[0002]

2. Description of the Related Art Conventionally, a sliding door body is suspended and held by a runner on an upper rail horizontally fixed upward, and a magnet guide pin which can be moved in and out by a magnetic force buried in a floor is protruded from the sliding door. Japanese Patent Application Laid-Open No. 4-68177 discloses a hanging sliding door that is inserted into a travel guide groove formed in a lower end surface of a main body to perform a slide travel guide. In this suspension type sliding door, a magnet or a magnetic material for attracting a magnet guide pin is attached to a traveling guide groove of the sliding door body, and the sliding door body is slid along the upper rail. When the sliding door body is moved directly above the magnet guide pin immersed in the floor, the magnet guide pin is pulled out by a magnetic force to be in a protruding state, and is inserted into the travel guide groove to perform a slide travel guide. is there.

[0003]

By the way, in the suspension type sliding door having the above structure, the magnet guide pin which is immersed in the floor is attracted by magnetic force and pulled up, and is inserted into the travel guide groove. In order to maintain the state, the distance between the sliding door body and the floor surface needs to be within a certain dimensional range (hereinafter, referred to as an appropriate distance). That is, if the distance between the sliding door body and the floor surface is smaller than the appropriate distance, the head of the magnet guide pin may strongly hit the lower end surface of the sliding door body and rebound, and may not be able to maintain the inserted state in the traveling guide groove. On the other hand, if the distance is larger than the appropriate distance, the magnetic force may not react to the magnet guide pin.

Conventionally, when adjusting the distance between the sliding door body and the floor surface to an appropriate distance, a runner having the sliding door body suspended from the upper rail and having a height adjusting function is used.
Height adjustment was performed with this runner. However, in the past, the height was adjusted with the runner while measuring with a measure etc. whether the gap between the sliding door body and the floor surface was an appropriate distance, so the worker could stand and bend. It had to be repeated several times, which was cumbersome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a suspension type sliding door capable of easily adjusting an interval between a sliding door body and a floor surface to an appropriate interval, and a height of the suspension type sliding door. An adjustment method is provided.

In order to solve the above-mentioned problems, a suspension type sliding door according to the present invention comprises a sliding door body mounted on an upper rail horizontally fixed upward through a runner having a height adjusting function. A plurality of magnet guide pins which are suspended and held so as to be able to run freely and are buried at intervals on a straight line parallel to the upper rail on the floor surface and which can be retracted and retracted by magnetic force are provided in the running guide grooves formed on the lower end surface of the sliding door body. In the hanging type sliding door where the slide traveling guide is performed by being inserted in the protruding state,
A spacer having a thickness within a range of an appropriate distance between the lower end surface and the floor surface is detachably attached to left and right end portions of a lower end surface of the sliding door main body.

In this suspension type sliding door, after the sliding door body having the spacer detachably attached to the left and right ends of the lower end surface is suspended from the upper rail via the runner,
By adjusting the height with the runner until the spacer comes into contact with the floor surface, further removing the spacer by lifting the sliding door body once, lowering the sliding door body again and suspending and holding the runner with the runner, The distance between the sliding door body and the floor can be set to an appropriate distance. In this case, it is possible to confirm that the space between the sliding door main body and the floor surface is an appropriate distance by contacting the spacer with the floor surface, so that the operation of adjusting the height with the runner as in the related art is interrupted halfway. Therefore, there is no need to measure the distance between the sliding door body and the floor surface, that is, the operator can complete the height adjustment in the runner by a consistent operation without repeating standing and bending operations. In addition, since the spacer is detachably attached to the left and right ends of the lower end surface of the sliding door body, after adjusting the height of the sliding door body, the spacer can be easily removed by slightly lifting the sliding door body. Will not get in the way later. As described above, the hanging type sliding door of the present invention can simplify the operation of adjusting the interval between the sliding door main body and the floor surface to an appropriate interval.

Further, since the spacer is detachably attached to the left and right ends of the lower end surface of the sliding door main body, the spacer protects the left and right corners of the lower end of the sliding door main body when packing and transporting the sliding door main body to the site. It can also be used as a protective material.

Here, the spacer may have a shape in which a groove fitting projection for fitting into the traveling guide groove is provided at a central portion of a main body portion interposed between a lower end surface of the sliding door main body and a floor surface. In this case, the spacer is unlikely to be displaced from both left and right ends of the lower end surface of the sliding door main body where the spacer is attached.
