Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a hanging fixture to a reinforcing frame that is fitted and fixed in order to reinforce the peripheral portion of door glass.

In general, this type of hanging bracket installation structure involves drilling a plurality of female screws along the door sliding direction into a fixing member fixed to the reinforcing frame, which engages with the locking part of the hanging bracket, and then attaching the screws to the female screws. It was installed by screwing together the locking part of the metal fittings. By the way, the opening width of the door glass installation location is not constant, so
The mounting dimensions of the hanging bracket in the door sliding direction may differ. However, in the above conventional hanging bracket mounting structure, the fixing member of the reinforcing frame is simply suspended and supported from the locking part of the hanging bracket, so when the hanging bracket is installed, the locking part of the hanging bracket and The female screws on the fixing member do not match. For this reason, we have prepared several types of fixing members, each with a female thread formed at the door glass installation location of the fixing member, or with multiple female screws formed according to the opening width of the door glass installation location of various sizes. I needed to. As a result, the labor required to install the hanging fittings increases, the efficiency of the installation work decreases, and it is necessary to manufacture members with various dimensions in a one-piece production manner, and the number of parts increases. This was undesirable as it led to increased costs. For this reason, a mounting structure for this type of hanging fitting is currently known, which has been proposed in order to eliminate the above-mentioned conventional drawbacks. This is a hanging metal fitting in which a long groove is formed along the longitudinal direction on the upper surface of the fixing member, and a locking plate formed to a predetermined size is inserted into the inside of the fixing member from above the long groove. The locking part is screwed into the locking part, and the locking part is configured to be movable and fixed relative to the fixing member. As a result, even if the mounting dimensions of the hanging bracket in the door sliding direction are different, the hanging bracket inserted into the long groove can be moved along this long groove, so the hanging bracket can be positioned at the desired spacing. However, it is necessary to form a long groove on the top surface of the fixing member along its longitudinal direction, and a locking plate with a long groove of the same shape as the long groove on the lower end of the fixing member. Since the receiving member is fixed, it increases the labor and time required to manufacture these long grooves, which is undesirable.

Conventionally, locking pieces are protruded from both sides of the inner surface of the upper opening of the reinforcing frame at the same height, a washer is placed on the lower surface of the locking piece, and the locking piece is held between the washer and the hanging fitting. However, there is a known device in which the hanging fitting can be fixed in any position with bolts, but with this, the length of the inward protrusion of the locking pieces on both sides cannot be increased, and the load-bearing strength is reduced. In addition, the reinforcing frame must be made wider, which increases costs.

In view of the above-mentioned drawbacks of the conventional art, the present invention is an improvement on the above-mentioned problems, and a hanging metal fitting having an L-shaped cross-section, which is vertically installed on the rail at the upper part of the entrance via a running wheel, is attached to a reinforcing frame having an H-shaped cross-section at the upper part of the door. In a glass hanging bracket installation structure for a sliding door that is connected so as to be movable and fixed relative to the sliding direction, square timbers are formed with locking recesses that are parallel to the door sliding direction and are staggered vertically on both sides. , a locking member having a substantially square cross section, which is fixed in the upper opening of the reinforcing frame, and has locking pieces that are vertically staggered on both sides to be fitted into locking recesses on both sides of the square timber; and a reinforcing frame. It consists of a hanging fitting whose bottom surface is brought into contact with the top surface of the opening of the hanging fitting, and a bolt which connects the square timber so as to be movable relative to each other in the vertical direction, and by tightening the bolt, the top surface of the square timber approaches the bottom face of the hanging fitting. Lift the locking piece of the locking member using the locking recess of the square lumber, and at the same time press the bottom of the hanging fitting to the top surface of the opening of the reinforcing frame to fix the hanging fitting and the reinforcing frame, and loosen the bolt to secure the above-mentioned fixation. This allows the depth of the locking recesses on both sides to be made deeper relative to the width of the square timber.In other words, the depth of the locking recesses on both sides can be adjusted to meet the required load-bearing strength. The width of the square timber can be reduced while maintaining the appropriate depth, and the thickness of the bolt that connects the hanging fitting and the square timber can be made sufficiently thick without being restricted by the depth (locking amount) of the locking recess. The present invention is designed to be able to use the same material, improve load-bearing strength compared to conventional products, and be provided at a low cost.
