Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a mounting column that mounts a column that supports a support arm that supports a telephone mounting table, for example, on a desk so as to be rotatable and axially connectable.

2. Description of the Related Art Conventionally, a mounting column having a supporting arm that supports a telephone mounting table or the like is rotatably mounted on a desk so as to be connectable in the axial direction. Is fitted to the fitting shaft or the fitting cylinder, and the support pipe and the fitting shaft or the fitting cylinder are attached by engaging the guide hole in the circumferential direction and the locking screw to rotate the shaft. It was configured to prevent slipping in the direction.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, according to the above-described conventional mounting strut, the locking screw and the guide hole for rotatably mounting the strut pipe to a desk or the like are exposed to the outside and the appearance is significantly impaired, and There are inconveniences such as the protrusion of the locking screw is an obstacle and the locking screw is easily loosened.

Means for Solving the Problems Therefore, the present application, in order to improve the inconvenience of the above, below the upper portion fixed to the lower inner circumference of the support pipe that supports the support arm, and fitted in the mounting pipe, and A hollow connecting cylinder formed integrally with a lower portion having an inclined surface formed on the lower surface, and inserted into the connecting cylinder so as to be tiltable and led out from the lower surface of the connecting cylinder, and a threaded portion is formed at the lead-out portion,
From a screw shaft having a head capable of rotating in a support pipe at the upper end, and a locking piece screwed to the screw portion of the screw shaft and having an inclined surface formed on the upper surface and joined to the inclined surface. The present invention is to provide a mounting pillar such as a telephone table which is characterized by including a connecting member, and in the above, a connecting cylinder is provided on the inner surface of the lower part of the pillar pipe so that the mounting pillars can be axially connected. A brim portion is provided between an upper portion to be fixed and a lower portion having an inclined surface formed on the lower surface, the lower portion having an outer diameter capable of being fitted in the support pipe, and the locking piece,
It has an outer diameter that allows it to float within the stanchion pipe, and preferably the screw shaft is made of a flexible material.

However, when mounting the support pipe to the mounting pipe, with the lower part of the connecting member fitted to the mounting pipe from above, use a tool such as a screwdriver to screw the shaft from above the supporting pipe. Rotate. Then, the locking piece also tries to rotate together with the screw shaft, but the inclined surface thereof abuts the lower inclined surface of the connecting cylinder, and the rotation of the locking piece is restricted.
The rotation of the screw shaft raises the locking piece to join the inclined surface of the connecting cylinder and the inclined surface of the locking piece, and when the screw shaft continues to rotate, the locking piece moves in the inclined direction due to the joining of the inclined surfaces. Since a component force is received, the screw shaft tilts in its inclination direction and the locking piece moves laterally, and the side surface of the locking piece presses against the inner surface of the mounting pipe, whereby the support pipe is connected via the connecting member. Fixed to the mounting pipe.

In the above, the connecting cylinder is provided with a collar portion between an upper portion fixed to the inner surface of the lower portion of the strut pipe and a lower portion having an inclined surface on the lower surface, and the lower portion can be fitted in the strut pipe. When the locking piece has an outer diameter and the locking piece has an outer diameter that allows free play in the support pipe, the support pipes can be sequentially connected in the axial direction by the same action as described above.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings. A is for mounting the support pillar of the present application, for example, on the outside of the support pipe (2) having an inner diameter substantially equal to that of the mounting pipe (1) embedded in the corner of the desk board B of the desk, and on the side of the upper end of the telephone mounting base. An outer cylinder body (5) having a support arm (4) supporting (3) mounted in a cantilever shape is attached to a pair of upper and lower spacing rings (6) a,
(6) Shows a support member that is rotatably fitted by b, and the rotation of the support pipe (2) and the outer cylinder body (5) is
It is regulated by the engagement between the head of the screw (7) provided on the strut pipe (2) and the engaging projection (8) protruding from the inner surface of the outer tubular body (5). The upper gap holding ring (6) a has a stepped notch (9) on the outer peripheral edge of the upper surface, and the lower gap holding ring (6) b has a stepped notch on the inner peripheral edge of the lower surface.

2), the upper portion of the collar portion (12) is fitted into the lower end portion of the strut pipe (2) by press fitting or welding, and the lower portion of the collar portion (12) is the mounting pipe (1). )
A hollow connecting cylinder (14) having an outer diameter that fits in the lower surface and an inclined surface (13) formed on the lower surface, and the head contacts the upper surface of the connecting cylinder (14) through a washer (15). The contact part is inserted in the connecting cylinder (14) so as to be tiltable, and the lower part is led out from the inclined surface (13) and the threaded part (16) is provided at the leading part.
And preferably a flexible screw shaft (17),
It is composed of a short shaft body, and the thread portion (16) of the screw shaft (17) is screwed into the shaft core portion thereof, and the connecting cylinder (1
4) and a locking piece (19) having an inclined surface (18) joined to the inclined surface (13), the screw shaft (17)
At the lower end of the locking piece (19), there is provided a bulging portion (20) for preventing the locking piece (19) from coming off. Reference numeral (21) denotes a cap fitted to the upper ends of the support pipe (1) and the mounting pipe (2), and the notch (9) of the upper gap holding ring (6) a is provided on the lower surface of the disk-shaped top. ) To a mounting rib (22) fitted to the outer peripheral edge of the upper part of the mounting pipe (1) and a fitting rib (23) fitted to the inner circumference of the upper end of the support pipe (2) to the mounting pipe (1). They are provided integrally with each other.

When attaching the arm member A to the attachment pipe (1), the lower portion of the connecting member (11) is inserted into the attachment pipe (1) from above to attach the flange portion (12) to the attachment pipe (1).
Column pipe (2) that comes into contact with the upper surface of the column and in this state the cap (21) has been removed using a tool such as a screwdriver
The head of the screw shaft (17) is rotated from above. Then, the locking piece (19) also tries to rotate together with the screw shaft (17), but the rotation of the locking piece (19) is restricted by the abutment of the inclined surfaces (18) and (13). The locking piece (19) rises due to the rotation of the screw shaft (17), and the inclined surface (1
