Description

[Detailed description of the invention] <Purpose of the invention><Industrial application field> The present invention relates to a supporting device such as a floor stool in a wooden building, and is particularly concerned with subsidence of the ground of the cobblestone portion that supports the floor stool. The present invention relates to a novel device which can always support a floor stool without causing it to rise even in such a case, and which can also be easily removed.

<Background of the invention> Cobblestones, which are one of the foundations of wooden buildings, support short pillar-shaped floor supports beneath the floor surface, but when phenomena such as ground subsidence occur, the floor seats become unstable. It lifts up from the boulders and cannot provide sufficient support. For this reason, in the past, if it was discovered that the floor stool had risen due to the subsidence of the cobblestone part, the countermeasure was to insert an additional piece of wood between the cobblestone and the floor stool, or to raise the floor stool. As a countermeasure, they applied an additional layer of mortar to the area.

However, even if this trend of ground subsidence in the cobblestone area stops, if it continues to progress, even if repairs are made, it is expected that the floorboards will eventually rise again due to subsidence, and it is necessary to repair them again. I had to.

<Technical matters for which the development was attempted> The present invention was developed in view of this background, and even in places where there is a tendency for constant subsidence, it is possible to automatically provide support as the subsidence progresses. This is an attempt to develop a new support device that can be adjusted to maximize the performance.

《Structure of the invention》 〈Means for achieving the purpose〉 That is, the supporting device such as a floor stool according to the present invention is provided with a movable support member that has a tendency to constantly expand on the main body, and a stopper is provided on the main body so as to be slidable. ,
On the other hand, the movable support is provided with locking flanges in multiple stages, and the stopper engages with the groove between the locking flanges and rotates within a certain angle range, thereby causing the stopper to This device is characterized in that the engagement position of the inclined guide surface formed at the tip is switched, thereby achieving the above object.

<Example> The present invention will be specifically described below based on the illustrated example. Reference numeral 1 denotes a support device for a floor stool or the like according to the present invention, which is, for example, a cobblestone 3 that supports the floor stool 2 on the lower surface of a wooden building.
It is used in place of or installed between the boulder 3 and the floor 2. The supporting device 1 for floor stools, etc. will be described in detail below.This device has a cylindrical main body 5 as an example, and the bottom part of the main body 5 is closed by a bottom plate 6, and the upper part is closed by a bottom plate 6. has an open structure. Of course, the usage pattern of the support device 1 such as this floor support device 1 can be used with either end facing upward, and it is not necessarily limited to the bottom plate 6 side of the main body 5 facing downward. However, in most cases, the bottom plate 6 is placed on the ground surface side, so for convenience, the bottom plate 6 side will be described below as the lower side. A movable support body 7 is slidably provided in the main body 5, and the movable support body 7 has locking flanges 8 in multiple stages around the movable support body 7. A bottom flange 9 having a larger diameter than the stop flange 8 is provided. Corresponding to the bottom flange 9, a stopper flange 10 is provided at the upper end of the main body 5 and projects like an inner flange. This prevents the movable support 7 from slipping out upwards. A support head 11 is provided on the upper end surface of the movable support 7, and the position of attachment to the movable support 7 can be freely adjusted.For example, the two are mutually adjusted by screws. Furthermore, a protruding spring 12 is installed between the bottom of the movable support 7 and the bottom plate 6 of the main body 5, so that the movable support 7 always protrudes upward relative to the main body 5. In other words, when looking at the entire supporting device 1 such as a floor foothold, its working length tends to increase. On the other hand, the movable support 7 is configured so that it cannot move further in the direction of contraction once it has expanded, and the stopper 13 directly takes on this action. That is, the stopper 13 is
For example, two units are provided facing each other on the circumferential surface of the stopper holder 14, and are slidably attached to the stopper holder 14. That is, the stopper 13
A locking end 15 is slidably fitted into the locking end 15, and an inclined guide surface 16 is formed on the locking end 15. Furthermore, a rod portion 17 is extended outward from the locking end 15, and a return spring 18 is provided so as to surround this rod portion 17. And rod part 1
An operating knob 19 is provided at the outer end of the lock 7, and the operating knob 19 includes a positioning protrusion 20 that projects toward the locking end 15. And this positioning protrusion 2
0, a projection receiving recess 21 is formed in the stopper holder 14, thereby setting the direction of action of the stopper 13. Furthermore, in this embodiment, a handle 23 is provided on the main body 5 for ease of handling.

The present invention has the specific structure as described above, and operates as follows to support the floor 2 on the ground that is prone to subsidence. First, replace the cobblestone 3 on the floating floor 2, or if there is a sufficient gap between the cobblestone 3 and the bottom surface of the floor 2, insert this device between them. do. During this insertion, the total length and total height of the support device 1 such as a floor scaffold must be sufficiently smaller than the distance between the bottom surface of the floor scaffold 2 and the ground surface, and this condition must be maintained. To make the settings, perform the following operations in advance. That is, as shown in FIG. 5a, the operation knob 19 of the stopper 13 is adjusted to the extension blocking side, and specifically, the inclined guide surface 16 at the locking end 15 of the stopper 13 is directed upward. Set to . In such a state, the locking end 15 engages with the groove 8a between the locking flanges 8 of the movable support 7, completely blocking the upward movement of the movable support 7. Of course, in this state, the support head 11 side of the movable support 7 is connected to the main body 5.
If the movable support body 7 protrudes further from the spring 12, the movable support body 7 may be moved to the protrusion spring 12 side by manual operation or the like and pushed down.
By this operation, the locking flange 8 is moved to the stopper 13.
Due to the action of the inclined guide surface 16 at the stopper 1
3 moves downward while pushing back in the unlocking direction, and comes to be locked in the next groove 8a. Of course, in addition to such an operation, as shown in FIG. When the movable support body 7 is kept at the position shown in FIG. After the overall working length of the support device 1 such as the floor scaffolding has been sufficiently shortened so that it can be inserted under the floor scaffolding 2, it is inserted under the bottom surface of the floor scaffolding 2 as shown in Fig. 4. Then, the operation knob 19 of the stopper 13 is operated to set the inclined guide surface 16 of the locking end 15 of the stopper 13 to be downward as shown in FIG. 5c. When this is done, the movable support 7 is always given an elongated tendency by the upward spring 12, and the locking flange 8 that abuts the locking end 15 of the stopper 13 comes into contact with the inclined guide surface 16. The movable support body 7 moves upward while moving in the unlocking direction, and stops extending at the position where the support head 11 of the movable support body 7 comes into contact with the floor support 2. Once set in this manner, the stopper 13 always tends to be biased toward the movable support 7 due to the action of the return spring 18, so it remains engaged in the groove 8a between the locking flanges 8. Become. In this state, the surface opposite to the inclined surface of the locking end 15 supports the locking flange 8, so the movable support 7 is set in a state where downward movement is completely prevented. . Therefore, even if the support device 1 for the floor scaffolding etc. descends due to ground subsidence, the movable support 7 automatically rises to compensate for the descent and always supports the floor scaffolding 2 without causing it to be in a floating state. .

One embodiment of the present invention has the configuration described above, and the following modifications are possible. That is, in the device shown in FIG. 6, this device is not installed below the floor 2, but is installed on the side, and is attached in an arm-like manner to the support head 11, which is the upper member of the movable support 7. A horizontal installation attachment 25 is attached, and the lower part of the floor support 2 is supported so as to be lifted up. Furthermore, the pitch of the support position of the movable obstacle 7 can be adjusted even more minutely by making the pitch of the locking flange 8 finer, but as shown in FIG. If the stopper 13 is provided on the surface and the operating position of each pair of stoppers 13 is shifted by a certain distance as shown by the symbol t, finer adjustment can also be made thereby. In addition to supporting floor supports, the present invention can also be used as support members for under-floor supports in theaters, gymnasiums, etc. where similar situations are expected.

<<Effects of the invention>> The present invention has the above-mentioned configuration, and is able to maintain complete floor coverage at all times while automatically adjusting the supporting height according to the amount of subsidence in the ground that tends to constantly subside. In addition, by switching the engagement state of the inclined guide surface of the stopper 13 during attachment/detachment, the tendency of the movable support body to extend can be prevented, thereby facilitating the attachment/detachment work.
