Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a guide roller mounting device, for example, an upper end or lower end of an opening / closing body such as a folding door for opening / closing an opening of furniture. The present invention relates to a device which is attached to a part or the like and opens and closes an opening and closing body along a guide rail.

(Prior Art) Conventionally, as a guide roller mounting device of this type, for example, a vertically long recessed recess is formed at an upper corner and a lower corner of an opening / closing body such as a folding door. A synthetic resin block-shaped roller mounting body in which a guide roller is rotatably protruded is embedded in the embedding recess, and is formed at one end of the upper and lower ends of the roller mounting body. There is a structure in which a screw is screwed into an inner wall portion of the buried recess from a mounting hole to fix the roller mounting body in the buried recess.

(Problems to be Solved by the Invention) In the above structure, since the block-shaped roller mounting body is buried and fixed in the buried concave portion, precision is required for forming the buried concave portion, and the embedded fixing of the roller mounting body is inaccurate. In this case, the guide roller tilts and the opening / closing operation of the opening / closing body is not smooth, so this assembling accuracy is required. In addition, since the guide roller is attached to the synthetic resin roller mounting body, the relationship with the weight of the opening / closing body However, there is a problem that reliability is easily impaired in strength.

Therefore, the present invention has been made in view of such a problem, and enables a guide roller to be accurately and simply and reliably assembled to an end face of an opening / closing body. It is an object of the present invention to provide a guide roller mounting device which can improve the workability of assembling and has high reliability.

[Configuration of the invention]

(Means for Solving the Problems) A guide roller mounting device of the present invention engages with a locking member embedded and fixed at an end face of an opening / closing body that opens and closes an opening along a guide rail, and the guide rail. A roller mounting body having a guide roller and engaged with an end surface of the opening / closing body,
The locking body has an insertion groove formed on both sides, and a locking step that is expanded is provided continuously inside the insertion groove on both sides, and the roller mounting body includes the opening and closing part. It has a horizontal engaging portion and a vertical engaging portion that engage with the end surface of the body, and is formed in an L shape, and a guide roller that engages with the guide rail via a vertical shaft is rotated on the horizontal engaging portion. The vertical engaging portion is provided with an insertion piece projecting into the insertion groove on both sides of the locking body on both sides of the vertical engaging portion, and the insertion end of the insertion piece is engaged with the locking step. A locking claw to be stopped is formed.

(Operation) In the guide roller mounting device of the present invention, the locking member is embedded in the end face of the opening / closing body, and the insertion of the both sides of the roller mounting body having the guide roller into the insertion groove on both sides of the locking body. By inserting the insertion pieces on both sides of the insertion groove deeply, the locking claw on the insertion end is automatically locked on the locking step inside the insertion groove, and the roller is mounted. The horizontal engagement portion of the body is engaged with a horizontal surface portion at the end surface of the opening / closing body, and the vertical engagement portion of the roller mount is engaged with the vertical surface portion at the end surface of the opening / closing body. Therefore, the roller mounting body can be easily and reliably mounted on the end face of the opening / closing body, and the guide roller of the roller mounting body can be accurately mounted on the end face of the opening / closing body.
