[Problem that the idea aims to solve]

However, the conventional telescopic fitting tube drive device uses only the telescopic fitting tube and the pulley. Therefore, the tube is subjected to compressive stress when the tube expands and the fitting tube rises. When the telescopic fitting tube is lowered, tensile stress is applied, so it is easy to break, and if If the tube is cut, the expansion fitting tube and pulley will no longer be connected, so the expansion There were problems such as the inability to raise and lower the contracted fitting tube.

[0007] This invention was created in view of the above points, and is highly durable and reliably expands and contracts. It is an object of the present invention to provide a telescopic fitting tube drive device capable of expanding and contracting a fitting tube.

【Example】

Next, an embodiment of the telescopic fitting tube drive device according to the present invention will be described with reference to the drawings. Figure 1 shows a telescopic fitting tube drive device 1 (hereinafter simply referred to as the device) which is an embodiment of the present invention. FIG. Device 1 is used, for example, in a corner pole of a car. , a case 2, a telescopic fitting tube 3, a winding part 4 (hereinafter referred to as a pulley), a flexible It is composed of members 6 and the like.

[0011] The case 2 is made of resin and has a substantially cylindrical shape. The upper part of this case 2 Among the contracted fitting tubes 3, the fitting tube 3a at the bottom is fixed by the base 7, and the fitting tube 3a is fixed by the base 7. The telescopic fitting tube 3 is constructed to stand up from the upper surface of the base 2. Also, expansion and contraction A lower opening 3b of the fitting tube 3 opens into the case 2.

0012 The telescopic fitting tube 3 combines multiple fitting tubes like a multistage rod antenna. It has a structure that allows it to expand and contract in the vertical direction by sliding adjacent fitting tubes. has been done. At the top of this telescopic fitting tube 3, there is a bush 8 which is a first holding member. Fixed installation. Furthermore, the bush 8 is equipped with an LED (Light Emitting Device). ) 9 is provided, and a transparent cover 10 is attached to cover this LED 9. ing. Furthermore, one end 6a of the flexible member 6 is fixed to this bush 8. .

[0013] The pulley 4 is a drum-shaped member installed inside the case 2, and is a second holding member. The bush 5 is fixed and rotated by a drive mechanism (not shown). ing. One end 6b of a flexible member 6 is fixed to the bush 5. This pulley 4 A guide groove is formed in the structure, and the flexible member 6 is wound along the guide groove. It has become. Therefore, if the pulley 4 is rotated in the direction of arrow A in Fig. 1 by the drive mechanism, it is possible to The flexible member 6 is sent out toward the telescopic fitting tube 3, and the telescopic fitting tube 3 is extended and moved in the opposite direction ( By rotating in the direction of arrow B), the flexible member 6 is wound around the pulley 4, and the telescopic fitting tube 3 is It is designed to shorten the time.

[0014] Next, the flexible member 6, which is the main part of the present invention, will be explained with reference to FIG. flexible part The material 6 is a flexible metal wire placed inside a flexible resin tube 11. 12 is inserted through it.

[0015] The resin tube 11 has one end 11a abutted against the bush 8, and is fixed to the tip of the telescopic fitting tube 3. The other end 11b is in contact with the bush 5. The bush 5 is fixed to the pulley 4. Also, the upper end of the metal wire 12 The portion 12a is covered with a cylindrical insulating member 13 such as a cylindrical tube, and the bush 8 is covered with a cylindrical insulating member 13. It is fixed to the bush 8 by caulking. Therefore, the bush 8 and the metal It is fixed in an insulated state from the ear 12. The upper end 12a of the metal wire 12 is L One terminal 9a of the ED9 is connected, and the other terminal 9b of the LED9 is connected to the bush 8. . As mentioned above, since the metal wire 12 is made of a conductive material, the metal wire 12 It also functions as a wiring cord to supply power to the LED 9.

[0016] In the above embodiment, the flexible member 6 is connected by the resin tube 11 and the metal wire 12. However, even if the flexible member is made of only metal wire, the telescopic fitting tube 3 can be expanded and contracted. It is possible to make it work. However, if only the metal wire is used, the space inside the telescopic fitting tube 3 will be There is a risk of wobbling in the middle part, and in order to prevent this, the resin tube is The structure of this embodiment in which the metal wire is inserted into the tube allows for smoother expansion and contraction movement of the expandable fitting tube 3. It is desirable for making people work. In addition, the metal wire 12 is made of a conductive material and used as a wiring cord. When used as a metal wire 12, the resin tube 11 also functions as an insulating material. This prevents a short circuit with the telescopic fitting tube 3 (which serves as the ground for the LED 9).

[0017] Further, although a conductive material is used as the metal wire 12 in the above embodiment, the present invention is not limited to this. Of course not.

[0018] Next, the expansion and contraction operation of the expansion and contraction fitting tube 3 will be explained.

[0019] First, when the telescopic fitting tube 3 is raised, the bush 5 is pushed by the driving force of the motor. , by pushing out the bush 5 with the tube 11 and wire 12, the telescopic fit is achieved. Joint pipe 3 rises. When descending, the bush 5 is pulled in by the driving force of the motor. Along with this, the bush 8 is pulled in by the wire 12, and the telescopic fitting tube 3 and the tube are pulled in by the wire 12. Since the tube 11 is not fixed to the bushes 5 and 8, it is not fixed to the lowering of the telescopic fitting tube 3. In this case, it plays an auxiliary role (support and insulation between the telescopic fitting tube 3 and the wire 12). Even if the tube 11 breaks, a force is applied to the tube 11 in the direction of compression when it rises. Since the fitting tube 3 only moves up and down, the telescopic fitting tube 3 can be raised and lowered.

[0020] In addition, since the tube 11 is not fixed to the bushes 5 and 8, the tube 11 A compressive force is applied to the telescopic fitting tube 3 when it rises, but no tensile force is applied to it, so The life of the tube 11 becomes longer.

[0021] Note that in this embodiment, the tube 11 was formed integrally, but it was divided into several parts. It is also possible to have a different configuration.

[0022]
