Description

  The present invention relates to a panel plate mounting device, and more particularly to a panel plate mounting device for mounting a panel plate on a vertical shaft or column of a frame.

  Conventionally, in order to attach the panel plate to the vertical shaft or support of the frame, a locking hole or opening is formed at a predetermined interval in the vertical direction on at least one front and back side of the frame vertical support or support, and the rear surface of the panel plate The lower corner portion on the side is provided with a downward hook to be engaged with the engagement hole or opening, the upper corner portion is provided with an engagement claw that is elastically engaged with the upper engagement hole or opening, and There is a known structure in which the downward hook is locked to the vertical hook of the frame or the lower locking hole or opening of the column, and the engaging claw is elastically engaged to the upper locking hole or opening.

  However, it is not only expensive to provide hooks and engaging claws on the back surface of the panel plate, but in the case of steel panel plates, when the hooks and engaging claws are also made of steel, The hooks and engaging claws may be deformed or damaged by repeated attachment and detachment, which has a problem in durability.

  As an improvement measure, in Patent Document 1, synthetic resin or aluminum or zinc made of hooks or engaging claws projecting at the four corners on the back side of the shell body formed by bending the edge plate on the back side of the steel surface plate. This is a panel plate structure fitted with a die-cast corner tool. More specifically, the edge plate of the shell body includes a side plate bent at a right angle to the back side around the surface plate, and a bent plate bent inward at the rear edge of the side plate, A crimping piece is formed at the end of the bent plate, and the corner tool is inserted between both side plates and the two bent plates adjacent to the surface plate of the shell, and the crimped piece is formed at a corresponding position of the corner tool. It was press-fitted into the recessed part.

However, since the corner tool is fitted to the edge plate of the corner portion of the panel plate and fixed by caulking of a part of the bent plate, the one described in Patent Document 1 is in principle attached to the corner tool. The position cannot be set with high accuracy. On the other hand, the vertical shaft of the frame or the locking hole or opening of the support column can be positioned with relatively high accuracy because it is stamped, so that the hooks and engaging claws of the corner tool are engaged. There has been a problem that it does not accurately engage with the edge of the blind hole or opening.

  In view of the above situation, the problem to be solved is that the panel plate can be easily and securely attached to the vertical shaft or support of the frame, and the manufacturing and mounting errors in the mounting structure are small, and the panel is free from backlash. The object is to provide a panel board mounting apparatus capable of mounting a board.

  In order to solve the above-mentioned problems, the present invention is detachably attached to vertical and horizontal openings formed in a vertical frame or a column of a partition panel using hooks and engaging claws provided on the back surface of the panel plate. The panel plate is formed by forming an edge portion around the back side of the steel surface plate, and forming a bent plate substantially parallel to the surface plate at least at both side edge portions. An attachment hole is formed in the upper and lower portions of the bent plate, and a lower connector having a downward hook is fitted in the lower attachment hole, and an upper connector having an engaging claw is fitted in the upper attachment hole. A panel plate mounting apparatus was constructed (claim 1).

  Here, the lower connector and the upper connector are molded parts made of synthetic resin, and formed with protrusions that are engaged with the upper and lower one side hole edges of the mounting hole at the upper and lower one side ends, and the upper and lower other side ends. Elastic engagement portions that are elastically engaged with each other in the retaining state are formed on the upper and lower other side hole edges of the mounting holes, and the hooks and the engaging claws are formed close to the side where the projections are provided. (Claim 2).

  The lower connector forms the protrusion at the lower end and the elastic engagement portion at the upper end, and the upper connector forms the protrusion at the upper end and the protrusion at the lower end. It is preferable that an elastic engagement portion is formed (claim 3).

  Further, the upper connector has a projecting piece projectingly provided on the upper portion of the engaging claw that elastically engages with the upper edge of the opening and abutting the lower edge of the opening below the engaging claw. It is more preferable to form (Claim 4).

  In the panel plate mounting device according to the first aspect of the present invention, since the mounting hole for fitting the lower connector and the upper connector is formed in the bent plate of the panel plate, the lower connector and the upper connector are connected. The mounting accuracy of the tool is increased, manufacturing errors and mounting errors in the mounting structure are small, the panel plate can be mounted without rattling, and the panel plate can be easily and securely mounted on the vertical shaft or support of the frame.

  According to the second aspect, since the lower connector and the upper connector are molded articles made of synthetic resin, the shape accuracy is high, and accordingly, the hook and the engagement when fitted into the mounting hole of the bent plate of the panel plate. The position accuracy of the claw is very high. Also, when mounting to the panel board, the projection on one side of the upper and lower sides is locked to the edge of the upper and lower side of the mounting hole, and the elastic engagement part on the other side of the upper and lower side is attached. Since it is merely elastically engaged with the upper and lower other side edge of the hole, it can be performed very easily. Furthermore, since the lower connector and the upper connector are formed by bringing the hook and the engaging claw close to the side where the protrusion is provided, the support strength is increased.

  According to the third aspect, the position where the protrusion and the hole edge of the mounting hole are locked is the lower end portion in the lower connector, and the upper end portion in the upper connector. The support strength is increased when the panel plate is attached to the vertical and horizontal openings formed in the vertical rod or support of the frame with hooks and engaging claws.

  According to the fourth aspect of the present invention, the engaging claw of the upper connector is elastically engaged with the upper edge of the opening and the projecting piece stops against the lower edge of the opening. And the backlash of the upper and lower sides can be reliably prevented in a state where the panel plate is attached to the vertical gutter or support of the frame.
