Description

  The present invention relates to a support post used for various purposes such as a flag pole for an advertising promotion, a heating rod, and a plant support means in agriculture and horticulture.

  Traditionally, natural bamboo has been used as this type of support. Natural bamboo is full of neatness, has both simplicity and texture, is friendly to the global environment, and is not a source of pollution. It is used as a flagpole for the lantern. However, when natural bamboo is used as a flagpole, it is not suitable for mass consumption because of its irregular shape. In addition, natural bamboo is difficult to replace because it is quickly damaged by sunlight and rain. Therefore, it can be said that natural bamboo is not very suitable for use as a flagpole.

  Moreover, as this kind of support | pillar, the support | pillar for agriculture and horticulture as shown, for example in FIG. 8 is devised. In this agricultural and horticultural support, a seal plug 14 is fitted to both ends of a support body 13 formed by coating the peripheral wall surface of the metal tube 11 with a synthetic resin film 12, and the inside of the support body 13 and the outside air are connected to the seal plug 14. It is assumed that a communicating air hole 15 is opened (Patent Document 1).

  The conventional support constructed as described above is improved in durability and aesthetics because the swelling phenomenon of the synthetic resin film 12 is eliminated.

  Further, as this type of support, for example, the one shown in FIG. 9 has been devised. This strut is formed with a flange portion 23 substantially equal to the outer shape of the metal tube 22 in the synthetic resin plug body 21 and a fitting portion 24 substantially equal to the inner diameter of the metal tube 22 at one end of the flange portion 23. 24 is attached to at least one end of the metal tube 22, and a synthetic resin coating layer 25 is formed from the outer peripheral side surface 22 a of the metal tube 22 to the outer peripheral side surface 23 a of the flange 23, and the end of the metal tube 22 is formed on the coating layer 25. It is assumed that an annular protrusion 26 is formed along the boundary between the portion and the plug 21 (Patent Document 2).

In the conventional strut configured in this way, the water tightness inside the metal tube 22 is achieved by the plug body 21 without the plug body 21 being pulled out, and the end of the metal tube 22 is supported by the annular protrusion 26. The bending strength at the boundary between the plug body 21 and the plug body 21 is high, the end portion of the covering layer 25 is not easily damaged, and the end portion of the support column is protected.

  Each of the above-mentioned conventional struts has a synthetic resin coating layer on the outer peripheral surface of the metal tube, and since this synthetic resin coating layer is in close contact with the metal tube, it is durable without peeling from the metal tube. It has an advantage that it can be used over a long period of time.

  By the way, in the current situation where such conventional struts are required to reuse resources in recent years and to separate and collect garbage separately, the synthetic resin coating layer and the metal tube can be easily disposed of at the time of disposal. Separation is desirable from the viewpoint of reducing labor and costs at waste disposal facilities.

  However, in the above-mentioned conventional support column, the coating layer of the synthetic resin is in close contact with the metal tube so that the synthetic resin and the metal cannot be easily separated at the time of disposal and are discarded as they are. Therefore, separation into synthetic resin and metal at a waste treatment facility, etc. requires a lot of labor and expense, and is often landfilled and cannot promote the reuse of resources. Had.

  In addition, even when the conventional support is used as a flag pole, the synthetic resin coating layer is only exposed, so that even if the color tone is changed, the appearance is monotonous and a cold impression is received. Had.

  Therefore, the present invention aims to solve the above-mentioned conventional problems, and can easily separate the synthetic resin and the metal at the time of disposal, enabling the synthetic resin and the metal to be separately collected, A strut that does not need to be separated into synthetic resin and metal at a waste disposal facility, etc., and that is suitable for resource reuse, and that has a natural feel and is softened.

A lower fitting portion 7b that fits the inner peripheral rib 7c, and an inner peripheral rib 7c that protrudes on the inner surface between the fitting portions 7a and 7b. The inner peripheral rib 7c is connected to the joint. It is assumed that it is inserted so as not to deviate from this joint.

  Since the column of this device is configured as described above, the synthetic resin and the metal can be easily separated at the time of disposal, the synthetic resin and the metal can be separated and collected, and the waste treatment. Since the facility does not need to separate the synthetic resin and metal, it is suitable for resource reuse. Furthermore, the pillar of this invention makes a natural texture feel and soften the heart when a natural bamboo pattern is formed on the outer peripheral surface of the synthetic resin tube.

  Hereinafter, the best mode for carrying out the support of the present invention will be described in detail with reference to the drawings.

  The column of this device is made of a synthetic resin tube 1, a metal tube 2 that can be inserted into the synthetic resin tube 1, and a synthetic resin made of metal resin 2 that stops the metal tube 2 from coming out of the synthetic resin tube 1. It consists of a stop pin 3. And the support | pillar of this invention has attached the synthetic resin plug body 4 made removable to the upper end part as needed, and attached the synthetic resin plug body 5 made removable to the lower end part. .

  The synthetic resin tube 1 has a natural bamboo pattern on the outer peripheral surface, and is similar to natural bamboo. It has a clean feeling like natural bamboo, and has both simplicity and texture. This is preferable. The synthetic resin tube 1 is provided with a through hole 1a at at least one location from the upper end to the lower end. In the illustrated example, the through-hole 1a is provided at one location of the lower end portion, but may be provided at one location of the upper end portion or at one location of the intermediate portion. Further, the hole 1a may be provided at all of the upper end portion, the intermediate portion, the lower end portion, or at any two of these locations.

  The metal pipe 2 is provided with a through hole 2 a at a position that matches the through hole 1 a of the synthetic resin pipe 1 when inserted into the synthetic resin pipe 1. The metal tube 2 has an outer diameter smaller than the inner diameter of the synthetic resin tube 1 and can be inserted into the synthetic resin tube 1. When the metal tube 2 is inserted into the synthetic resin tube 1, the synthetic resin tube 1 It is preferable to keep the gap between 1 and 1 as small as possible.

  As shown in FIG. 6, the retaining pin 3 includes a disc-shaped head 3a, a leg 3b protruding from the center of the inner surface of the head 3a, and heads on both sides from the tip of the leg 3b. It is assumed that an elastic locking piece 3c that protrudes obliquely outward in the direction of the portion 3a is provided. Then, when the metal tube 2 is inserted into the synthetic resin tube 1 and the through hole 1a of the synthetic resin tube 1 and the through hole 2a of the metal tube 2 are made to coincide with each other, The leg 3b is pushed into 2a and is prevented from falling off by the elastic locking piece 3c. That is, the elastic locking piece 3c of the stop pin 3 is pressed inwardly in the through holes 1a and 2a, and the leg portion 3b is pushed in until the inner surface of the head 3a contacts the outer surface of the synthetic resin tube 1. Then, the elastic locking piece 3c that has passed through the through holes 1a and 2a expands outward and returns to its original state. Even if it is attempted to remove the locking pin 3 from the through holes 1a and 2a, the elastic locking piece 3c. Will not come off when it hits the inner surface of the metal tube 2, so that the stop pin 3 will not fall out of the through holes 1a, 2a.

  Next, as shown in FIG. 2, the post of the present invention is obtained by dividing the synthetic resin pipe 1 and the metal pipe 2 into a plurality of pieces, and the plurality of synthetic resin pipes 1 and a plurality of pieces. The metal pipes 2 can be connected to each other. When the length of the device of the present invention exceeds 2.0 to 3.0 m, it is bulky to transport and store. Therefore, the synthetic resin tube 1 and the metal tube 2 are divided into two parts or divided into three parts. be able to.

  In such a case, before inserting the metal pipe 2 into the synthetic resin pipe 1, the metal pipe 2 divided into a plurality of pieces is connected in advance. In order to connect the metal tubes 2, as shown in FIG. 5, the lower ends of the upper metal tubes 2 are squeezed into a smaller diameter than the upper ends of the lower metal tubes 2. To fit. Although not shown, the upper end of the lower metal tube 2 may be squeezed into a smaller diameter than the lower end of the upper metal tube 2 so that the upper and lower ends of these metal tubes 2 are fitted. Further, in order to connect the metal pipes 2 to each other, as shown in FIG. 7, the upper half of the connection pipe 6 having an outer diameter substantially the same as the inner diameter of the metal pipe 2 is connected to the lower end of the upper metal pipe 2. The upper end of the lower metal tube 2 may be extrapolated to the lower half of the connecting tube 6. Although not shown, the lower half of the connecting pipe 6 having an outer diameter substantially the same as the inner diameter of the metal pipe 2 is inserted and fixed to the upper end of the lower metal pipe 2, and the upper half of the connecting pipe 6 is fixed. Alternatively, the lower end of the upper metal tube 2 may be extrapolated.

  In order to connect the synthetic resin pipes 1, the lower end of the upper synthetic resin pipe 1 and the upper end of the lower synthetic resin pipe 1 have the same diameter, and the upper and lower ends of these synthetic resin pipes 1 are simply in contact with each other. However, as shown in FIG. 5, the cover 7 can be covered with a synthetic resin cover 7 so that the joint is not conspicuous. The cover 7 has an upper fitting portion 7a that fits the end portion of the synthetic resin pipe 1 above the joint, and a lower portion that fits the end portion of the synthetic resin tube 1 below the joint. It has a fitted part 7b and an inner peripheral rib 7c projecting on the inner surface between these fitted parts 7a, 7b, and this inner peripheral rib 7c is fitted into the joint, and this connection I try not to get out of my eyes.

  And when using the support | pillar of this invention for a flagpole, the plug body 4 which adheres to an upper end part shall consist of the upper protrusion part 8 and the lower insertion part 9, as shown in FIG. A presser body 8a is screwed to the upper projecting portion 8. By screwing the presser body 8a, a flag support rod (not shown) inserted into the support hole 8b of the upper projecting portion 8 is pressed. To support it. The lower insertion portion 9 is loosely fitted to the collar 10 with a collar 10 interposed in the metal tube 2. In this way, when the wind hits the flag while the support bar is supported by the support hole 8b of the upper protrusion 8, the lower insertion part 9 rotates according to the wind direction, so the support bar also rotates together. Thus, the flag can be seen from each direction, and the advertising effect is excellent.

  Furthermore, the plug body 5 to be attached to the lower end portion of the column of the present invention is simply fitted into the outer peripheral surface of the synthetic resin tube 1 or is fitted into the metal tube 2 as shown in FIG. It is possible to have a fitting portion 5a.

  The column of the present invention configured as described above is used as a flag pole for outdoor advertising or as a support means for plants in agriculture and horticulture. The bodies 4 and 5 are removed, and the metal tube 2 is pulled out from the synthetic resin tube 1. In this case, the head 3a of the retaining pin 3 exposed on the surface of the synthetic resin tube 1 is cut off by inserting a cutter knife or a blade edge between the synthetic resin tube 1 and the head 3a. Then, since the leg 3b and the elastic locking piece 3c of the set pin 3 fall into the metal tube 2, they can be taken out from the lower end of the metal tube 2 with the plug body 5 removed.

  Further, in the column of this invention, in the case where a plurality of synthetic resin tubes 1 and a plurality of metal tubes 2 are connected to each other, these connections are removed and the synthetic resin tube 1 and the metal tube 2 are divided. .

  Then, if the synthetic resin tube 1, the retaining pin 3, the plugs 4, 5 and the cover 6 are collected together and the metal tube 2 is collected separately, the synthetic resin and the metal are separated and discarded. Therefore, the synthetic resin and the metal can be collected separately.

  Therefore, the column of the present invention does not need to be separated into a synthetic resin and a metal at a waste disposal facility or the like, and is suitable for resource reuse.

  In addition, since the metal tube 2 is inserted in the synthetic resin tube 1 even when the post of this device has been damaged as a result of being used for many years, the damage of the metal tube 2 is small. Only the metal tube 2 can be reused.
