JP, 2006-60754, A

  However, in the above-described conventional example, since the television mounting bracket is performed by locking the hook-type locking bracket in the long hole of the support post, it can be installed only at the position where the long hole is opened. As a result, there is a problem that the degree of freedom of the installation position is extremely low.

  The present invention has been made to solve the above-mentioned drawbacks, and it is an object of the present invention to provide a support post which can adjust the mounting position of the connector steplessly.

  Another object of the present invention is to provide a support post structure using the above support post, and a flat screen television support apparatus.

According to the invention said object is
A hollow metal support 1,
And a wooden column 2 inserted and fixed in the hollow portion of the metal support 1;
The metal support 1 is provided with a connecting opening 4 which is narrower than a hollow portion over a predetermined length in the longitudinal direction and which has a lip 3 left at the side edge,
This is achieved by providing a support post (A) to which the connector 6 can be connected by means of the clasp 5 screwed into the wooden column 2 exposed from the connection opening 4.

  The support column (A) is formed by inserting and fixing the wooden column 2 in the hollow portion of the hollow metal column 1 in which the connection opening 4 is opened for a predetermined length.

  In the present invention in which the wooden column 2 to which the fastener 5 can be screwed is exposed to the outside from the connection opening 4 over a predetermined length, the fixing position of the connector 6 is the screwing position of the fastener 5 to the wooden column 2 It becomes possible to adjust in a stepless manner by changing.

  In addition, in the case where the connecting opening 4 has a lip 3 remaining on the side edge in a front view, that is, when the metal support 1 is formed with a hollow rectangular cross section, for example, By forming it into a C-channel shape, it is possible to prevent the wooden columnar body 2 from falling off from the metal column 1, and to obtain a second moment of area close to the closed cross-sectional shape. In addition to being placed, sufficient strength against bending load and buckling load is exhibited.

  Furthermore, the lip portion 3 improves the strength of the wooden columnar body 2 against buckling load or bending load by restricting the amount of movement in a direction orthogonal to the axis of the wooden columnar body 2, and as a result, a supporting column (A) Improve the overall strength.

Although it is possible to form the wooden columnar body 2 into a length that can be inserted over the entire length of the metal support 1 in advance,
If a support post (A) is constructed in which a replenishment opening 8 is opened on the side wall of one end portion of the metal support 1 to allow insertion of the additional wood columnar body 7 into the hollow portion, if necessary It is not necessary to prepare long wooden pillars 2 in advance, since it is possible to add the additional wood pillars 7 at any time and to secure the freedom of the connection position of the connector 6. It becomes possible to aim at reduction.

  In addition, since the replenishment opening 8 is opened in the side wall portion of the metal support 1, the wooden pillars 7 for addition can be used even in a state where both ends of the metal support 1 are closed, that is, installed in a predetermined position. It becomes possible to insert into the metal support 1 to change the connection position of the connector 6.

The support columns (A) can be installed sideways by fixing both ends to the opposing wall surface, or can be installed vertically between the floor surface 13 and the ceiling surface 12, but when installed vertically To
It has a barbed head 11 at one end provided with a barbed plate 10 in which a thin plate steel material obtained by cutting and raising a large number of triangular projections 9 is hardened,
The projections 9 of the barbed head 11 can be pressed against the ceiling surface 12 to construct a support column (A) that can be erected on the floor surface 13.

  In the present invention, the projections 9 of the barbed head 11 are pressed against the ceiling surface 12 in a state where the support columns (A) are erected on the floor surface 13. Penetration or penetration between minute bumps and dips, and pressure contact generates a large frictional force at each contact point with the ceiling surface 12. As a result, since lateral displacement of the upper end portion can be reliably prevented, it is possible to effectively prevent the falling of the support post (A).

Furthermore, as another aspect of the present invention for achieving the above object,
The barbed head 11 is urged upward and mounted on the upper end of the metal support 1 so as to be vertically movable.
The wooden columnar body 2 is supported on a floor surface 13 so as to project from the lower end of the metal support 1 so as to be movable back and forth.
In addition, the metal support 1 can be configured as a support support (A) on which the female screw portion 14 of the attachment 5 to be screwed into the wooden column 2 is formed.

  The lower end of the wooden column 2 projects from the lower end of the metal column 1 to form the leg of the support column (A), and the clasp 5 held by the female screw 14 of the metal column 1 is made into the wooden column 2 By screwing in, since it becomes possible to adjust the full length of the support column (A) steplessly, it becomes possible to set the press-contact force to the ceiling surface 12 in the barbed head 11 high.

  That is, in the case where the support pillar (A) whose upper end is urged by the spring in the extension direction can be bridged between the floor surface 13 and the ceiling surface 12 because the stepless length adjustment is impossible, the support pillar is made in advance. With the total length of (A) adjusted to be longer than the height of the room, the spring is bent to move the lower end to a predetermined position, and the lower end is moved to the floor 13 by eliminating the deflection of the spring. It is necessary to press it.

  As a result, the effective deflection amount of the spring for generating the pressure contact force to the ceiling surface 12 becomes smaller than the deflection amount at the initial stage of the installation work. Since the maximum amount of deflection of the spring consumed for the installation work increases as the distance between the set positions of the support columns (A) increases, the amount of deflection of the spring at the completion of the installation becomes too small and the predetermined amount There is a possibility that the pressing force can not be secured.

  Although this problem can be dealt with by reducing the length adjustment step or reducing the spring constant of the spring, in the case of the former, it is necessary to provide a large number of screwing points, and the structure is complicated. And, there is a problem that the cost increases.

  Even in the latter case, since it is necessary to increase the deflection amount after increasing the number of turns of the spring or increasing the coil diameter, it is necessary to increase the size of the spring, resulting in an increase in cost, Or it causes degradation of assembly workability.

  On the other hand, the support column (A) in the present invention capable of stepless adjustment of the entire length bends the spring etc. until the barbed head 11 is pressed against the ceiling with a predetermined pressing force against the biasing force. The wooden columnar body 2 can be pulled out until the lower end reaches the floor surface 13 and the projecting dimension can be determined by the fastener 5 and installed. As a result, it is possible to design the spring easily and inexpensively, since it is not necessary to allow for the absorption by the spring to the dimensional change at the time of the installation operation and at the completion of the installation.

Furthermore, by using the support post (A),
The support post (A);
And a connecting body 6 connected to the support post (A) via the post connecting portion 15,
The column connecting portion 15 has a connecting piece 16 corresponding to the connecting opening 4 forming surface of the metal support 1 and a bearing piece 17 corresponding to the opposite surface to the connecting opening 4 forming surface.
A pillar support structure in which a bolt-like clasp 5 having a flat free end to be screwed into the female screw portion 14 formed on the connection piece 16 is pushed into the wooden pillar 2 and fixed to the support pillar (A) can do.

  In the present invention, the column support structure is formed by fixing the connecting member 6 such as the shelf board and the shelf support to the supporting column (A) according to the application, and fixing of the connecting member 6 to the support column (A) is This is performed via the column connecting portion 15 which is formed integrally with the connecting body 6 or separately from the connecting body 6 and is connected to the connecting body 6 by appropriate means.

  The column connecting portion 15 has a connecting piece 16 and a bearing piece 17 which are disposed at substantially the same distance as the space between the wall surface of the metal column 1 where the connecting opening 4 is formed and the wall surface opposite thereto. A female screw portion 14 is formed on the connection piece 16 by welding or burring a nut.

  Connection of the connector 6 to the support column (A) is achieved by pushing the clasp 5 held by the female screw portion 14 into the wooden column 2 with the clamping piece directed to the connection opening 4 of the metal column 1. By forming the female screw portion 14 in the connector 6, it is possible to use a bolt-like clasp 5 having a flat free end as a connection means without using a tapping screw with a sharp tip or a wood screw. .

  The bolt-like clasp 5 which has obtained the propulsive force in the female screw portion 14 is compared to the case where a wood screw or the like whose tip functions as a hook is used to enter the predetermined depth while crushing the wooden columnar body 2. In addition to being able to prevent cracking and the like of the wooden columnar body 2, since the projected area with respect to the horizontal surface is large, the shear resistance is also increased, and the fixing strength can be improved.

In addition, by using the support post (A),
Support post (A),
And a television connecting device 18 fixed to the wooden column 2 of the support post (A) by means of a fastening piece 5;
The television connecting device 18 rotatably connects the movable side base 21 for fixing the flat television 20 to the lower end of the fixed side base 19 connected to the support column (A), and the fixed side base 19 and the movable side base 21 Between the two, one end is fixed to one side and the other end is connected by a belt-like surface fastener 22 which is attached to the other in a variable attachment position,
By adjusting the sticking position of the belt-shaped surface fastener 22 to the fixing surface fastener, it is possible to configure a flat-screen television support device capable of adjusting the depression angle of the flat-screen television 20.

  In the present invention, the television connecting device 18 has a simple structure in which the column support and the movable side base 21 are rotatably connected, so that the manufacturing cost can be reduced, and the belt-like surface fastener 22 can be attached. Since the depression angle of the screen of the flat-screen television 20 can be adjusted only by adjusting the wearing position, usability is also improved.

  According to the present invention, the mounting position of a connector such as a flat-screen television can be adjusted steplessly.
