Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a rotary telephone stand in which a telephone mounting stand is rotatably attached to a support mounted on the top of an office desk or the like.

Conventional technology Conventionally, a rotary telephone stand is constructed by rotatably attaching a mounting stand to a support member erected on the top of an office desk or the like so that the telephone can be oriented in a direction convenient for the user. It is publicly known.

Problems to be Solved by the Invention However, in the conventional structure, since a bending moment due to the load of the telephone acts on the support, the support tends to bend to some extent during long-term use. When the support is bent to some extent, even if you rotate the mounting base and point the phone in the desired direction, the mounting base will automatically rotate in the direction of the bending of the support with the slightest shock. There were some inconveniences when using it.

Therefore, the present application aims to improve the above-mentioned defects of the conventional devices.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application provides a fixing column that is erected on the upper piece of a support member that is formed in a U-shape and is attached to a top plate, etc. The lower end of the rotary support is rotatably supported via a guide member, and an engagement piece having a flange is fitted to the upper end of the fixed support, and a mounting plate is attached to the lower edge. A support cap provided with a notch that engages with the bracket is fitted into the upper end of the rotary column, and a protrusion that can be engaged and detached at a plurality of positions is provided between the flange and the inner surface of the support cap. and a concave portion, respectively. In the above, in order to guide the rotation of the support cap, a center hole is formed in the flange of the engagement piece, and a continuous concave portion is formed in the outer peripheral surface of the center hole. Further, the inner surface of the support cap is provided with a guide shaft that fits into the center hole and a protrusion that engages and disengages from the recess.

For example, when the support member is attached to a top plate or the like by tightening screws and the mounting base is rotated to orient the phone in a direction that is convenient for the user, the lower end of the rotating support will move through the guide member. Further, the upper ends of the rotating columns rotate around the respective fixed columns via the caps, and during the rotation, the protruding shaft and the recess are repeatedly engaged and disengaged. When the mounting table is rotated in a desired direction, the mounting table will not be rotated randomly by the shock due to the engagement between the protrusion and the recess.

Reference numeral 8 denotes a guide member rotatably fitted to the lower part of the fixed support 7, which includes a narrow-diameter upper part 8a having a plurality of annular protrusions arranged in the height direction on the outer periphery and a locking protrusion 9, and an inner part 8a. It consists of a lower part 8b with a large diameter, which has a stopper piece 10 that partially contacts the pin 6 and restricts the rotation of the guide member 8. The lower end of the rotating support 11, which is slightly shorter than the fixed support 7, is fitted by press-fitting, and the notch 12 provided at the lower end is locked to the locking protrusion 9, so that the rotating support 11 rotates around the outer periphery of the fixed column 7 together with the guide member 8. Reference numeral 13 denotes a disc-shaped pressure contact plate having an elastic piece 14 such as rubber attached to the lower surface and an annular rib 15 on the outer periphery, and 16 a member screwed into the screw hole 4 of the screw piece 5 at the center. As shown in FIG. The operating member 16 and the press plate 13 are rotatably fitted together, and the operating member 16 and the press plate 13 are rotatably connected by a screw 19 at the center thereof. 20 is an engagement piece fitted to the upper end of the fixed support 7, and has a large diameter flange 21;
A central hole 22 is formed in the center, and a plurality of concave portions 23 are continuously formed in the outer peripheral surface. Reference numeral 24 designates a notch 2 that fits on the outer periphery of the upper end of the rotating support 11 and engages with a bracket 27, which will be described later, on a part of the lower edge.
A support cap having a diameter of 4', in the center of its inner surface,
A guide shaft 25 that fits into the center hole 22 and a protrusion 26 that engages and disengages from the recess 23 are integrally provided on the peripheral surface. Reference numeral 27 denotes a bracket protruding from the outer periphery of the upper part of the rotating support 11, and a mounting piece 29 provided on the rear lower surface of the mounting table 28 is attached to this bracket so that the mounting table 28 is in a horizontal state. Reference numeral 30 denotes a cap-shaped lower cover into which the top surface of the lower outer periphery of the guide member 8 is fitted, the lower end of which abuts the upper surface of the top plate A, and hides the upper half of the support member 1.

Therefore, the support member 1 is placed on the top plate A of an office desk, etc.
To fix the lower cover 30 upward, the edge of the top plate A is inserted between the abutment piece 2 and the pressure plate 13, and the lower surface of the pressure plate 13 is fixed to the top plate A.
When the grip portion 18 of the operation member 16 is gripped and rotated in this state, the screw shaft 17
By screwing into the screw hole 4 of the screwing piece 5, the support member 1 is lifted up and the contact piece 2 comes into contact with the lower surface of the top plate A. Next, when the grip portion 18 is strongly rotated, the pressure contact plate 13 strongly presses the top surface of the top plate A without rotating, and the support member 1 is firmly fixed to the top plate A.

In this state, when the lower cover 30 is lowered, its lower surface comes into contact with the upper surface of the top plate A, and the operating member 16
