Description

  The present invention relates to a device support pole clamping device for fixing a pole for supporting a display of a computer or other office equipment to a desired height position on a desk or table to a top plate such as a desk.

  Conventionally, office equipment such as telephones and computer displays are not placed directly on the top of the desk but at a specified height, so that the top surface can be used effectively and is easy to see and use. In order to obtain the above convenience, a device in which a pole is fixedly erected on the top plate and equipment is mounted on a support arm attached to the pole is widely used.

  By the way, conventionally used means for fixing the pole to the top plate is such that the lower end of the pole c is fixed to the upper surface of the upper side b of the clamp body a having a substantially U shape in side view as illustrated in FIG. A set screw e is screwed on the same axis as the pole c of the lower side portion d of the clamp body a, and the seat plate f and the upper side portion b are rotatably attached to the inner end of the set screw e. The side end of the top plate g is sandwiched between the bottom plate and the head h of the set screw e is turned and tightened to clamp the top plate g and fix the pole c.

  However, in the above-described conventional clamping means, when the equipment is present under the top plate g, such as a dealing desk, or when there is no gap between adjacent desks, the set screw e is used. In order to tighten, hands and tools could not be inserted under the top plate g, and it was extremely difficult to firmly establish the pole c.

  Therefore, when clamping the pole c, the desk must be moved one by one to create a gap in which the set screw e can be rotated, and it is not easy to attach and detach the pole c.

  Therefore, recently, as can be seen in the known document 1, there has been proposed one in which the pole can be clamped to the top plate from the upper surface side of the top plate.

In the known document 1, a seat plate is rotatably integrated with a lower end of a pole inserted into an upper side portion of the clamp body, and a lower side portion of the clamp body is brought into contact with a lower surface of a side end portion of the top plate. Then, the pole is screwed and lowered by other means so that the lower side and the seat plate are clamped to the top plate.

  However, in the technique described in the above-mentioned publicly known document 1, when the pole is fixed (clamped) to the top plate, the pole itself is rotated according to the thickness of the top plate and is sandwiched between the top and bottom plates. If the moving mechanism is a screw type, the clamp body must be supported by hand until the seat plate reaches the upper surface of the top plate, and there is a problem that the fixing operation is extremely troublesome.

  Even if the vertical movement mechanism of the pole can be moved up and down quickly by adopting means other than screws, such as a means for moving the pole up and down by operating the handle or a vertical movement means using a motor, The dynamic mechanism is remarkably large or complicated and expensive, and it is difficult to simply configure the periphery of the pole.

  The present invention is not only capable of attaching the pole from the upper surface side of the top plate, but also facilitates the fixing operation of the pole, can be simplified in structure, and can be provided at low cost. Separately, a presser plate that abuts on the top surface of the top plate is provided, and this presser plate is configured separately from the pole and can be moved up and down independently. The presser plate and the lower side of the clamp body are clamped to the top plate. After that, a pole is inserted into the upper side of the clamp body, and the lower end thereof is received by the presser plate to support the pole.

  As a result, the clamping operation to the top plate can be easily performed, and the structure can be simplified.

  That is, the invention according to claim 1 is a lower side portion that engages with the lower surface of the top plate of a desk or table, an upper side portion that is positioned away from the upper surface of the top plate, and a side portion that connects the lower side portion and the upper side portion. A clamp body formed in a substantially U shape when viewed from the side, and a presser plate that is between the upper side part and the lower side part and is cantilevered so as to be movable in the vertical direction on the side side part and is in contact with the upper surface of the top plate A pole that is supported by penetrating the upper side of the clamp body, and a pole positioning portion that positions the lower end of the pole is formed on the upper surface of the presser plate, for supporting devices such as a display on the pole. At least one support arm is attached.

  In this way, when attaching the pole, if the lower side of the clamp body is in contact with the lower surface of the side end of the top plate and the presser plate is lowered and brought into contact with the upper surface of the top plate, The main body is fixed to the top plate, and the clamp main body does not fall off the top plate even if the hand is released from the clamp main body.

  Next, if the pole is inserted into the upper side portion of the clamp body and the lower end thereof is fitted into the pole positioning portion of the holding plate, the pole is erected in a vertical posture.

  In this case, in order to make the pole non-rotating, the lower end of the pole has a polygonal cross section such as a quadrangle, and the pole positioning portion of the presser plate is a polygonal concave portion corresponding thereto, and both are fitted to prevent rotation. do it.

  Further, the upper side portion insertion portion or the whole of the pole may have a polygonal cross-sectional shape, and the hole on the upper side portion may be a polygonal hole corresponding thereto to prevent rotation.

  When it is necessary to securely fix the pole as well as to prevent the pole from coming off, a nut member is fixed to the lower side of the upper side of the clamp body as in the second aspect of the invention, and the lower part required length of the pole is fixed. A male screw portion that is screwed into the nut member may be formed in the range, and the male screw portion may be erected by being screwed into the nut member. At this time, if the lock nut is screwed into the base portion of the male screw portion, it is possible to reliably prevent the pole from coming loose.

  As the cantilever support structure of the presser plate, a rising portion is formed at one end of the presser plate, and a set screw inserted into the rising portion is vertically attached to a side portion of the clamp body. It is preferable that the clamp body is fixed to the top plate by being inserted into a long hole drilled in the direction and fastening the set screw in a state where the lower surface of the presser plate is pressed against the upper surface of the top plate. .

  The pole positioning part formed on the presser plate can be constituted by a concave part in which the lower end of the pole can be fitted as closely as possible, and the concave part is constituted by an annular member fixed to the upper surface of the presser plate. Can do.

  As described above, according to the present invention, a pressing plate is provided separately from the clamp body and pole that are substantially U-shaped in side view, and can be fixed after adjusting the vertical position along the side portion of the pressing plate clamp body. Since the clamp body is fitted to the side edge of the top plate, the clamp body can be attached to the top plate by lowering the presser plate and bringing it into contact with the top surface of the top plate. Can be easily and quickly attached to the top plate.

  Since it is only necessary to stand the pole on the clamp body after the clamp body is attached, it is possible to eliminate the troublesome work of clamping the clamp by operating the pole.
