However, since the above-mentioned bracket and support member are directly screwed to a structure such as a wall surface, a hole must be formed in the structure. The work of drilling holes in the structure is complicated, so that the workability is poor. Also, it is not preferable to make holes because the appearance after removing the brackets etc. is impaired, and especially in the case of rental housing, the permission of the landlord etc. must be obtained for installation, so the procedure is It is troublesome.

Further, when the bracket or the support member is mounted on the ceiling, it must be screwed upward using a stepladder or the like, which is inferior in workability. In addition, when the bracket or the support member is to be removed at the time of moving or the like, the fixing screw may be rusted and cannot be easily removed.

In order to solve this problem, it is conceivable to install and fix an extendable bar between structures, but it is difficult to fix the bar in a state where it is stretched with a strong force. . For this reason, workability is poor, and there is a case where a heavy object cannot be supported without obtaining a sufficient tension force.

Accordingly, the present invention is capable of mounting a bracket and a support member without making a hole in a structure, and also can easily install and remove the bracket and the support member, and obtain a sufficient support force. It is an object of the present invention to provide a support column that can be used.

In order to achieve the above object, according to the present invention, two longitudinal members slidable with respect to each other in a longitudinal direction, and each longitudinal member is disposed between a building structure. A supporting column having a fixing mechanism for relatively fixing the elongated members in a stretched state, wherein one of the elongated members is slidable in the longitudinal direction with respect to the elongated member, and An end member that is displaced between a state protruding from the distal end and a state where the end member is pushed into the elongate member and directly receives the pressing force of the elongate member and is transmitted to a structure; The fixing mechanism is provided with a jack portion that slides and extends the longitudinal member and an operating portion that operates the jack portion. The invention according to claim 2 is a fixing device for fixing two longitudinal members relatively to each other in a state where the two longitudinal members are slidable with each other in a longitudinal direction and each of the longitudinal members is stretched between structures of the building. A support column with a mechanism, wherein any of the longitudinal members can contact the structure, and one of the longitudinal members is slidable in the longitudinal direction with respect to the longitudinal member and a tip of the longitudinal member. And a biasing means for biasing the end member in a direction of pressing the structure against the structure. A jack portion is provided for sliding and extending the member, and an operation portion for operating the jack portion is provided.

[0008] Therefore, a support pole can be stretched and attached between the structures, and a clothesline, a planter, and the like can be installed on the support pillar, so that the structure can be installed without making a hole. Become. In addition, since the support columns can be installed between the structures by extending the support columns using the jack portion, there is no need to fix each of the long members while applying force by hand so as to stretch between the structures. Can be easily installed, and a strong supporting force can be obtained.

Further, when the support pillar is provided between the structures and is gradually extended, the end member is pushed into the longitudinal member against the biasing means. It can be temporarily fixed during. For this reason, the fine adjustment of the installation position and inclination of the support pillar can be performed in a state where the support pillar is temporarily fixed, so that the support pillar can be easily positioned.

In addition, since the direction of the rotation center of the operation unit is different from the extension direction of the support pillar,
The movable range of the operation section can be increased, and the operability when extending the support column can be improved.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on an example of an embodiment shown in the drawings.

FIG. 1 shows an embodiment of a support column 1 according to the present invention. The support column 1 is composed of two longitudinal members 2 and 3 slidable in the longitudinal direction, and the longitudinal members 2 and 3 in a state where the respective longitudinal members 2 and 3 are stretched between structures 4 of a building. And a fixing mechanism 5 for relatively fixing.

One of the longitudinal members 2 and 3 urges the end member 6 slidable in the longitudinal direction at the end of the longitudinal member 2 and the direction in which the end member 6 is pressed against the structure 4. And an urging means 7. The end member 6 protrudes from the tip of the elongated member 2 as shown in FIG. 1 and is pressed into the elongated members 2 and 3 to directly apply the pressing force of the elongated members 2 and 3 as shown in FIG. It is displaced into a state of receiving and transmitting to the structure 4.
In addition, the fixing mechanism 5 includes a jack portion 8 that slides and extends the longitudinal members 2 and 3 and an operation portion 9 that operates the jack portion 8. For this reason, as shown in FIG. 3, the support pillar 1 is stretched and attached between structures 4 such as the floor and ceiling of the veranda, and a bracket 10 and a tent 11 supporting a clothesline are installed on the support pillar 1. Therefore, the structure 4 can be installed without making a hole. In addition, since the supporting column 1 can be installed between the structures 4 by extending the support column 1 using the jack portion 8, the longitudinal members 2 and 3 are fixed while applying force by hand so as to be stretched between the structures 4. There is no need to support
Can be easily installed and a strong supporting force can be obtained.

In this embodiment, as shown in FIG. 4, each of the two longitudinal members 2 and 3 has a square pipe shape, and one of the longitudinal members 2 is inserted into and guided by the other longitudinal member 3 while sliding. It is movably provided. The outer longitudinal member 3 is set on the lower side, and the inner longitudinal member 2 is set on the upper side. The end member 6 and the urging means 7 are provided at the upper end of the upper longitudinal member 2, and the fixing mechanism 5 is provided at the overlapping portion of the upper and lower longitudinal members 2, 3.

A mounting groove 12 is formed on one side of the upper longitudinal member 2 along the longitudinal direction. This mounting groove 12
Has a jaw 12a that is rectangular in cross section and narrows the opening from the side. For this reason, by inserting the head of the bolt 13 inside the mounting groove 12 as shown in FIG.
The bolt 13 is slidable up and down and the elongated member 2
Will not come off to the side of. And this bolt 13
For example, a bracket 10 or a tent 1 for supporting a clothesline
1 can be screwed on. Since the bolt 13 can be moved up and down, the installation height can be adjusted before the tent 11 or the like is screwed.

On the other hand, as shown in FIG. 5, the end member 6 has a sliding shaft
Receiving plate 15 fixed to the tip of the sliding shaft 14, a swinging plate 17 provided at the tip of the sliding shaft 14 via a spherical spacer 16, and a rubber plate adhered to the swinging plate 17 And a base plate 19 screwed to the base end of the sliding shaft. The swing plate 17 and the rubber plate 18 swing around the spacer 16. For this reason, even when the mounting surface of the structure 4 is inclined or has irregularities, the ability to follow the mounting surface of the end member 6 can be enhanced and the supporting force can be increased. In addition, since the rubber plate 18 is provided, it is possible to increase the friction with the structure 4 to be in contact with, prevent the lateral displacement, and increase the supporting force. Can be suppressed.

A bearing 20 for slidably supporting the sliding shaft 14 of the end member 6 is mounted on the upper portion of the upper longitudinal member 2. The base plate 19 of the end member 6 and the bearing 2
0, a biasing means 7 comprising a tension coil spring is attached. Therefore, when the end member 6 is pushed into the longitudinal member 2, the base plate 19 is pushed down and the urging means 7 is extended as shown in FIG. Then, the receiving plate 15 is pushed until it comes into contact with the longitudinal member 2. At this time, the pressing force from the longitudinal member 2 to the structure 4 is as follows: the longitudinal member 2 → the receiving plate 15 → the spacer 16 → the swing plate 17
→ It is transmitted to the structure 4 via the rubber plate 18. Since the end member 6 is interposed between the elongated member 2 and the structure 4 in this manner, temporary fixing can be performed using the end member 6 used when the support column 1 is fully supported. In addition, the stability of the support column 1 during temporary fixing can be improved.

Then, as shown in FIG.
When the support pillar 1 shorter than the distance is provided between the structures 4 and 4 and gradually extended, the protruding end member 6 comes into contact with the structure 4 (FIG. 2B). When the support column 1 is further extended, the end member 6 is pushed into the longitudinal member 2 against the urging means 7. At this time, the support column 1 can be temporarily fixed between the structures 4 by the urging force of the urging means 7. In a state where the support column 1 is temporarily fixed, fine adjustment of the installation position and the inclination of the support column 1 can be performed, so that the support column 1 can be easily positioned.

Also, the jack portion 8 of the fixing mechanism 5
As shown in FIG. 1, a female screw portion 21 is fixed to one longitudinal member 2 so as not to rotate, and a male screw portion 22 rotatably attached to the other longitudinal member 3 and screwed to the female screw portion 21. . The female screw portion 21 is made of, for example, a nut and fixed to the upper longitudinal member 2 by welding or the like. The male screw portion 22 is rotatably attached to the lower longitudinal member 3 via a thrust bearing 23. That is, the jack portion 8 constitutes a screw jack. By using the jack, the support column 1 can be extended with a strong force only by operating the operation unit 9 with a small force. Therefore, a strong tension force of the support column 1 can be obtained. Further, since the male screw portion 22 is supported by the plurality of thrust bearings 23, 23,
The tension state of the longitudinal members 2 and 3 can be firmly maintained.

Further, the operating section 9 has a rotating shaft 25 rotatably provided inside the elongated member 3 so as to be orthogonal to the longitudinal direction.
And a crank-shaped handle 26 that can be attached to and detached from the support shaft 1 on the rotating shaft 25. Since the rotating shaft 25 is provided inside the longitudinal member 3, the handle 26
By removing, unnecessary protrusions are eliminated, and it is possible to prevent a person or an object from being caught. The rotating shaft 25 of the operation section 9 and the male screw section 22 are connected by a bevel gear 24.

For connection between the handle 26 and the rotating shaft 25, for example, a hexagonal hole 25a is formed in the head of the rotating shaft 25, and a hexagonal column-shaped projection 26a fitted in the hole 25a is formed in the handle 26. In advance, the hole 25a and the projection 26a are fitted to each other. Accordingly, the male screw portion 22 can be rotated via the rotating shaft 25 and the bevel gear 24 by attaching and rotating the handle 25 to the rotating shaft 25. Therefore, the direction of the center of rotation of the operation unit 9 can be made different from the longitudinal direction of the support column 1 and the radius of rotation of the handle 25 can be increased, so that operability can be improved.

A grounding member 27 is attached to the lower end of the lower longitudinal member 3. A rubber plate 28 is attached to the ground surface of the ground member 27 as shown in FIG. Thereby, it is possible to enhance the supporting force by increasing the friction to the contacting structure 4 and to prevent the structure 4 from being laterally displaced, and to prevent the surface of the structure 4 from being damaged.
The grounding member 27 enters the inside of the longitudinal member 3 and is fixed by screwing. The grounding surface of the grounding member 27 is formed in a circular shape sufficiently larger than the thickness of the longitudinal member 3. Therefore, there is an effect of preventing the support column 1 from falling down.

The procedure for installing the above-described support column 1 between the ceiling and the floor of the veranda as shown in FIG. 3 will be described below.

The entire length of the support column 1 is made shorter than the interval between the structures 4 in advance, and the support column 1 is set up between the structures 4 (FIG. 6A). Then, the handle 26 is attached to the support column 1 and rotated to operate the jack portion 8 to extend the support column 1.

When the support column 1 is further extended after the end member 6 abuts on the structure 4, the end member 6 is pushed into the longitudinal member 2 against the urging means 7 (FIG. 2B). At this time, the support column 1 can be temporarily fixed between the structures 4 using the urging force of the urging means 7. That is, the support column 1 remains standing without falling down even if the hand is released.

Further, by rotating the handle 26 to extend the support column 1, the end member 6 is completely pushed into the elongated member 2 (FIG. 2C). At this time, the longitudinal member 2 and the end member 6 come into contact with each other in the longitudinal direction, and the two longitudinal members 2 and 3 and the end member 6 are in contact with each other between the structures 4 without interposing the spring member. Become. When the handle 26 is rotated to set the tension force appropriately, the handle 26
Is removed (FIG. (D)). Thus, the mounting of the support column 1 is completed.

However, the present invention is not limited to this, and as shown in FIG. May penetrate completely into the longitudinal member 2 so that the longitudinal member 2 directly contacts the structure 4. That is, in this support column 1, both of the two long members 2 and 3 can contact the structure 4, and one of the long members 2
Is slidable in the longitudinal direction with respect to the longitudinal member 2 and protrudes from the tip of the longitudinal member 2 (FIG. 9A) and is housed in the longitudinal member 2. State (FIG. 1B).

In this support column 1, a receiving portion 30 is attached to an end of the upper longitudinal member 2. The receiving portion 30 can directly contact the structure 4 and has a space 31 for completely housing the end member 6. When the support column 1 is in the temporarily fixed state, as shown in FIG. 9A, only the end member 6 is in contact, and the longitudinal member 2 is not in contact. Here, the longitudinal member 2
Is further extended, the end member 6 is accommodated in the receiving portion 30 of the elongated member 2 as shown in FIG.
Comes into direct contact with In this case, the elongated member 2 that is extended comes into direct contact with the structure 4, so that the stability of the support column 1 after attachment can be increased.

Further, in each of the above-described embodiments, a tension coil spring is used as the urging means 7, but the present invention is not limited to this, and a compression coil spring may be used. In this case, a fixing plate is provided inside the longitudinal member 2, and the urging means 7 is compressed between the sliding shaft 14 and the fixing plate to obtain the drag of the end member 6.

Further, in each of the above-described embodiments, each of the longitudinal members 2 and 3 has a square pipe shape. However, the present invention is not limited to this. For example, as shown in FIG. The longitudinal member 3 is formed in a round pipe shape, or although not shown, the upper longitudinal member 2 is formed in a round pipe shape, the lower longitudinal member 3 is formed in a square pipe shape, or each of the longitudinal members 2 and 3 is formed in a round pipe shape. It can be shaped. As shown in FIG. 10, when the upper longitudinal member 2 has a square pipe shape and the lower longitudinal member 3 has a round pipe shape,

[0038]

As is apparent from the above description, according to the supporting columns according to the first and second aspects of the present invention, the supporting columns are attached to the structures by being stretched, and the hanging poles and the clothespins are attached to the supporting columns. Since a planter or the like can be installed, it can be installed without making a hole in the structure. For this reason, it is not necessary to drill a hole at the time of installation, so that the workability can be improved, and since the hole does not remain after the bracket or the like is removed, the appearance can be maintained well.

Further, since the support columns can be installed between the structures by extending the support columns using the jacks, there is no need to fix each of the longitudinal members by applying a force by hand so as to stretch between the structures. In addition, it is possible to facilitate the installation work of the support pillar and obtain a strong support force.

Moreover, since the support column can be easily removed by loosening the jack portion, the workability when changing the installation position of the support column or when moving is improved.

Further, since the supporting column can be temporarily fixed between the structures by the urging force of the urging means, it is possible to finely adjust the installation position and the inclination of the supporting column while the supporting column is temporarily fixed. Thus, the positioning of the support columns can be easily performed.

In particular, in the support column according to the first aspect, since the end member is interposed between the elongated member and the structure, the end member used for fully supporting the support column is used. Temporary fixing can be performed, and the stability of the support pillar at the time of temporary fixing can be enhanced. Further, in the support column according to the second aspect, since the elongated longitudinal member is in direct contact with the structure, the stability of the support column after attachment can be increased.

According to the third aspect of the present invention,
Since the jack portion is a screw jack, even if the operation portion is operated with a small force, a strong tension force of the support column can be obtained. In addition, since the direction of the rotation center of the operation unit is different from the extension direction of the support column, the movable range of the operation unit can be increased, and the operability can be improved.
