Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for mounting a tabletop panel such as a desk panel, a tabletop telephone stand, a tabletop tray, etc., which is arranged on a tabletop, a counter, or the like, and more specifically, to a tabletop unit. The present invention relates to a desktop unit mounting device that can be mounted at any position with simple operation.

[0002]

[Prior Art]

 When a tabletop panel or board is mounted on a tabletop such as a desk or a counter, as shown in, for example, Japanese Utility Model Publication No. 2-40817, a screw passed through a mounting bracket is attached to a side end surface of the tabletop panel or the tabletop. It is common to screw the desktop panel to both side end faces of the top plate or the rear end face through the mounting brackets by screwing them into the rear end face. However, since such a mounting device requires complicated screwing work, assembly workability is poor. In addition, in a desk or the like where appearance is important, a cover for covering the mounting bracket is required separately, which increases the number of parts and increases the cost. Also, in the case of a tabletop panel that is smaller than the width of the tabletop, it is often necessary to change the position of the tabletop panel to the left, right, or center of the tabletop when the desks, counters, etc. are relocated. According to the method, when the mounting position of the desktop panel is changed, the original screw hole remains, which is exposed to the outside and deteriorates the appearance.

On the other hand, a telephone stand, a paper tray, a lighting stand, etc. used on a tabletop such as a desk or a counter are simply placed on the tabletop or attached to the lower ends of their supporting legs. In general, a vise-type fastener is used to fix the top edge of the top plate by sandwiching it from above and below. However, if this kind of table-top unit is placed directly on the top plate, the work space on the top plate is narrowed and the workability of office work deteriorates. On the other hand, in the case of the method of clamping the edge of the top plate with the vise type fasteners provided at the lower ends of the columns, it is necessary to rotate the operation lever inserted into the tightening bolt many times, so the installation workability is improved. Is bad. Also, since the vise type fastener projects out of the side end surface or the rear end surface of the top plate, it is not preferable in appearance, and the vise type fastener interferes with the installation of desks and the like without any gap. There is a problem that you cannot do it.

For the purpose of eliminating the above-mentioned drawbacks of the prior art, for example, desk-top unit mounting devices have been proposed as disclosed in Japanese Utility Model Publication Nos. 62-32499 and 63-5558. This attachment device guides the support legs of the tabletop unit to the lower part of the top plate by using the opening groove for storing the cord formed along the rear edge of the top plate, and opens it in the code storage part under the top plate. The lower end of the supporting leg is fixed to a mounting rail structure arranged parallel to the groove by a bolt-nut tightening type fastener. In the case of such a mounting device, the supporting legs of the tabletop unit do not project outside from the side end surface, rear end surface, etc. of the top plate, and the fasteners are hidden under the top plate, so the appearance is neat. It becomes a thing. Further, since the mounting position of the fastener on the mounting rail structure can be adjusted arbitrarily, there is also an advantage that the tabletop unit can be arranged at any position on the top plate along the opening groove.

[0005]

[Problems to be solved by the device]

 However, in the conventional desktop unit mounting device that uses the opening groove, as described above, the bolt / nut tightening type fastener provided at the lower end portion of the supporting leg allows the lower end portion of the supporting leg to be positioned below the opening groove. Since it is configured to be fastened to the mounting rail structure that is provided, complicated bolt tightening work is required, and there remains a difficulty in mounting workability.

Therefore, it is an object of the present invention to provide a tabletop unit mounting device that allows a tabletop unit to be installed on a tabletop by a simple operation.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, a mounting rail that extends parallel to the opening groove is provided below the opening groove formed along the rear edge of the top plate of a desk, a counter, or the like. A desk unit mounting device that inserts a supporting leg extending from a tabletop unit placed on the above into an opening groove, and detachably attaches the supporting leg to a mounting rail with a fastener provided at the lower end of the supporting leg. The tool is provided with an operation lever that can be rotated in the forward and reverse directions, and a clamp portion that switches between two positions, a position for fastening the mounting rail and a position for releasing the mounting rail, according to the forward and reverse rotation of the operation lever. It is configured.

[0008]

[Action]

 In the desk-top unit mounting device configured as described above, the fastener provided at the lower end of the supporting leg fastens the operating lever that can rotate in the forward and reverse directions and the mounting rail that fastens in accordance with the forward and reverse rotation of the operating lever. Since it is equipped with a clamp that switches between two positions, one for opening and one for releasing, it is necessary to rotate the operating lever many times, unlike when tightening with tightening bolts and nuts is used. The clamp part can be easily tightened and fixed at any position on the mounting rail below the opening groove of the top plate by only one-touch operation.
