Abstract

(57) [Summary] [PROBLEMS] To provide a temporary holding mechanism for an inner body of a floor bundle so that the inner body does not suddenly drop when the screw is removed. An inner body 4 and an outer body 5 can be freely inserted and removed. An adjustment tightening body 6 is attached to the upper end of the outer body 5, and the split nut 12 accommodated therein moves inward and outward to engage and disengage with the screw 7 of the inner body 4. The split nut 12 has an elastic tongue piece 16, and when the split nut 12 moves outward, the tongue piece 16 projects inward due to the contact relationship with the nut retainer 13 and engages with the internal body screw 7.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an improvement of a floor bundle that stands between the floor pulling and the ground to support the floor of a building such as a house, and particularly when the height adjusting portion is unscrewed. The present invention relates to a temporary holding mechanism for an internal body that prevents the internal body from dropping suddenly.

[0002]

[Prior art]

 A floor bundle whose height is adjustable by a screw method has already been proposed. The structure of this floor bundle is composed of both the inner and outer bodies that are fitted and joined to each other so that they can be inserted into and removed from each other, and the adjusting tightening body of the joint portion. A split nut is movably accommodated inside the tightening body, and when the split nut is moved outward to unscrew from the inner body, the inner body can be rapidly moved up and down. In addition, by moving the split nut inward and screwing it in, the height can be finely adjusted.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional floor bundle, if the split nut is moved outward and the screw is unfastened, there is no support for the inner body, so there is a drawback that the inner body will drop at once. On there was a difficulty.

In view of such a point, the present invention prevents the sudden drop of the inner body by moving the split nut outwardly and temporarily holding the inner body at the position when the screwing is released. The purpose of the present invention is to provide a temporary holding mechanism for the internal body that improves workability.

[0005]

[Means for Solving the Problems]

 The technical means of the temporary holding mechanism for the inner body of the floor bundle according to the present invention is an inner body having a screw formed on the outer surface, an outer body into which the inner body is removably inserted and coupled, and an adjusting body attached to the upper end of the outer body. In a floor bundle consisting of a tightening body and a split nut that is movably accommodated in the adjustment tightening body and that is engaged with and disengaged from the internal body screw, an elastic tongue is attached to the split nut so that the split nut does not come out. When it is moved inward, the tongue protrudes inward and engages with the internal thread.

A tongue piece may be integrally provided on a side edge of the split nut so that the tongue piece can be projected and retracted by a contact relationship with the nut retainer.

[Embodiment of device]

 An embodiment of the temporary holding mechanism of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a state of use, in which a floor bundle 1 is erected between a bund stone 2 placed on the ground and a large pull 3 of the floor. The floor bundle 1 is entirely made of hard plastic, and includes an inner body 4 and an outer body 5 that are detachably connected, and an adjusting tightening body 6 provided at the connecting portion.

As shown in FIG. 2, a screw 7 having a saw-tooth shape is formed on the outer surface of the inner body 4, and a large catch 8 is attached to the upper end thereof. The outer body 5 has a cylindrical shape, and the inner body 4 is fitted therein so that it can be freely inserted and removed. The adjustment tightening body 6 includes a tightening body upper portion 10, a tightening body lower portion 11, and a ternary nut 12. The lower part 11 of the tightening body is rotatably attached to the upper end of the outer body 5. The lower part 11 of the tightening body is provided with three nut retainers 13 protruding upward, and a split nut 12 is fitted between the nut retainers 11 as shown in FIG.

The upper and lower parts 10, 11 of the tightening body are rotatable relative to each other. Further, since the nut retainer 13 is integrated with the tightening body lower portion 11, the split nut 12 is affected by the nut retainer 13 during this relative rotation. Further, 14 is a guide wall of the tightening body upper portion 10, 15 is a guide protrusion of the split nut 12, and the guide wall 14 and the guide protrusion 15 are disengaged from each other during relative rotation. As a result, the split nut 12 is moved in the radial direction by the relative rotation of the upper and lower portions 10 and 11. In order to make the split nut 12 move smoothly, the upper and lower end surfaces of the split nut 12 are guided by guide grooves (not shown).

FIG. 3 shows a state where the split nut 12 is moved inward by being pushed by the guide wall 14, and at this time, the split nut 12 and the internal screw 7 are screwed together. Therefore, if the upper and lower tightening bodies 10 and 11 are integrally rotated in this state, the inner body 4 moves up and down. Further, FIG. 4 shows a state in which the split nut 12 is fitted in the concave portion of the guide wall 14, and the split nut 12 is separated from the internal screw 7. Therefore, the internal body 4 can freely move up and down.

Reference numeral 16 is a tongue piece integrally formed on the side edge of the split nut 12. Since the tongue piece 16 is made of plastic, it has an appropriate elasticity. When the split nut 12 is in the inward position, the tongue piece 16 is in a non-protruding state as shown in FIG. 3, but when the split nut 12 moves outward, the contact relationship with the nut retainer 13 is as shown in FIG. And then the tip of the tongue piece 16 fits into the thread groove of the inner body screw 7. As a result, the inner body 7 is temporarily held at that position and a sudden drop is prevented. This temporary holding depends on the elasticity of the tongue piece 16, and the temporary holding can be released by applying a little force, so that there is no hindrance to the rapid vertical movement of the inner body 4.

The present invention is not limited to the above-described embodiments, but can be freely modified and implemented within the scope of the claims of the utility model. In particular, the shape of the tongue piece 16 and the number of attached tongue pieces 16 are arbitrary.

[0013]

[Effect of device]

 In the temporary holding mechanism of the present invention, when the split nut is disengaged from the internal body screw, the tongue projects and engages with the internal body screw, so the internal body is held at that position by the tongue and does not fall suddenly. Absent. Further, this temporary holding is only lightly locked by the elasticity of the tongue piece, and this temporary holding can be released by applying a little force, so there is no hindrance to the rapid vertical movement operation of the internal body. Further, since the tongue piece is elastic and flexible, it does not break or break due to collision or contact with the inner body.

According to the second aspect of the present invention, the tongue piece is retracted and retracted due to the contact relationship with the nut retainer, so that the retracting operation is reliable and there is no malfunction or failure, which is practically useful.
