Description

  The present invention relates to a structure for attaching a bracket for supporting a top plate to a leg of a desk. More specifically, the top plate is supported on the leg cylinder without using a screwing ring or the like welded to the inside of the leg cylinder. The present invention relates to a mounting structure for fixing an industrial bracket.

  Conventionally, in a desk of a type that supports a top plate by columnar legs, the top plate and legs are reduced in weight, and a frame member attached to the lower part of the top plate in order to supplement the strength of the connection, and the frame In order to make the legs and the legs rigid, a metal member such as a bracket for supporting the top plate disposed on the frame corner portion is provided.

  In particular, for design or design reasons, the strength (especially stability against forces acting from the side) is maintained when the legs need to be placed at or outside the four corner edges of a rectangular top, for example. Therefore, it is required that the top plate lower frame, the bracket and the leg are strongly integrated.

  For this reason, generally, a method is employed in which a top plate support bracket is screwed onto the upper surface of the leg cylinder body by a screwing ring welded or the like inside the leg cylinder body, thereby securing the strength of the coupling. (See, for example, Patent Documents 1 and 2).

  However, depending on the method, the heat applied to the inside of the leg tube body of the screwing ring for screwing the support bracket may distort the leg surface and damage the aesthetics. There was a problem that did not finish on the street.

  In addition, in order to use the screwing ring welded to the inside of the leg tube body in a stable manner in correspondence with the screwed portion of the bracket for supporting the top plate, the positioning requires a high degree of precision. As long as this condition is not satisfied, the unity of the top plate, the bracket and the leg cannot be obtained, and problems such as rattling during use cannot be avoided.

Furthermore, when it is desired to adopt a thin cylindrical leg that cannot be screwed into the screw ring, the above method cannot be used in the first place, and the frame attached to the bottom of the top plate and the leg are firmly connected. It was extremely difficult to make it rigid.

It is possible to increase or decrease the outer diameter or the width formed by the contact surfaces Fc and Lc that contact each of the inner wall surfaces of the leg cylinder T and the convex contact surface Fn.

  That is, the leg attachment portion A can be pressed against the inner surface of the leg cylinder T by sliding the movable portion L with respect to the fixed portion F by the rotation of the screw rod S.

  In addition to the above configuration, the fixed portion F has the following configuration.

  That is, the upper end portion of the fixing portion F is formed on the flange-like portion Vo except for the portion integrated with the short beam portion M, and the leg cylinder T is formed on the lower surface side of the flange-like portion Vo. It is formed on a receiving edge R that is in close contact with the inner surface Tw of the upper end portion.

  In addition, an inner edge Vi parallel to the lower surface of the flange-shaped portion Vo is formed on the lower surface of the short beam portion M coupled to the fixed portion F.

  On the other hand, the upper end portion of the leg cylinder T fitted around the fixing portion F has a portion (inner edge Vi) where the fixing portion F and the short beam portion M are coupled to bulge downward in the leg cylinder T. A concave notch Ti is formed to escape the portion (see FIG. 7).

  As a result, when the top plate support bracket B is attached and fixed to the leg cylinder T, (a) the fixing portion F against the rattling of the leg cylinder T in the inner and outer directions (left and right directions in FIGS. 1 and 2). The inner edge Vi and the notch Ti at the upper end of the leg cylinder T, (b) the abutment surface Fc of the fixed part F, the abutment surface Lc of the movable part L, and the inner surface of the leg cylinder T, (c) the fixed part F The lower surface Ve and the receiving edge R of the flange-shaped portion Vo and the upper end surface Tu and the inner surface Tw at the upper end portion of the leg cylinder T interact with each other, and this can be reliably and effectively suppressed.

  Further, for the rattling of the leg tube T in the left-right direction (perpendicular to the plane of FIG. 1 and FIG. 2), (d) the lower surface Ve of the flange portion Vo in the fixing portion F and the outer peripheral surface of the receiving edge R Left and right sides (the front side and the other side in FIG. 1 and FIG. 2) and the upper end surface Tu and the inner side Tw of the upper end portion of the leg cylinder T, and (e) the notch portion Ti of the leg cylinder T. The notched side surface and the vertical surface Vw that holds the inner edge Vi in the short beam portion M interact with each other, and rattling can be suppressed as described above.

  With the configurations (a) to (e) above, it is possible to completely prevent the leg cylinder T from rattling in the inner and outer directions or the left and right directions with respect to the mounting portion A. It becomes possible to fix to B reliably.

  Next, an example of a procedure for attaching the top plate support bracket B in the present embodiment will be described.

  First, the fixed portion F and the movable portion L constituting the leg mounting portion A of the top plate support bracket B are integrally connected in advance by a screw rod S loosely screwed into the insertion hole H and the screw hole Sc ( (See FIGS. 5 and 6).

  Subsequently, the leg attachment portion A in which the fixed portion F and the movable portion L are integrated is inserted into the upper opening of the leg cylinder T (see FIG. 7). This state is shown upright in FIG.

  As shown in FIG. 2, the fixing portion F is provided with a screw hole Fb for positioning the leg cylinder T through a hole Tb provided in the leg cylinder T.

  Therefore, when inserting the leg attachment portion A, the leg tube T is positioned on the leg attachment portion A by inserting the hole Tb and the screw hole Fb and screwing the positioning screw b into the screw hole Fb. To do.

  Here, since the screw b is screwed into the screw hole Fb of the fixed portion F in the leg mounting portion A, even if the screw rod S tightening the fixed portion F and the movable portion is loosened for some reason, The cylinder T does not fall off from the mounting portion A.

  Then, the screw rod S, which is loosely screwed into the insertion hole H and the screw hole Sc, is tightened by an appropriate screwing means, and the movable part L is slid along the guide G provided in the fixed part F. By the cooperation of the part F and the movable part L, the outer diameter formed by the contact surface Fc including the convex contact surface of the fixed part F and the pressure contact surface Lc of the movable part L is increased to increase the leg attachment part. A can be firmly pressed and fixed to the inner wall surface of the leg cylinder T.

  The application of the mounting structure of the present invention is not limited to the present embodiment, and it goes without saying that it can be implemented as a mounting structure for legs or columns of any furniture and fixtures including desks and chairs.

  The present invention is as described above, and the leg mounting portion of the top plate support bracket can be pressed and fixed to the inner surface of the leg tube body simply by sliding the movable member with respect to the guide formed on the fixed portion. This eliminates the need to weld a special screw ring to the inner surface of the leg tube body. As a result, the surface of the leg tube body is not distorted and the appearance of the product is not impaired, and is fixed by screwing means such as screws. Because the bracket is fixed to the leg by pressing the movable member, positioning is not required to be as precise as the screw ring, and the screw ring is Even if it is a thin leg cylinder that cannot be welded, the top plate support bracket can be easily and securely attached to the leg as long as the leg mounting part can be inserted. It is very useful when applied to the mounting structure of the support bracket.
