  Most of the objects to be fixed project hollow or solid support legs below the bottom four corners, for example.

  Although the conventional anti-falling fixture can be attached to the body of the object to be fixed, it is difficult to attach it to the support leg of the object to be fixed.

  In addition, there is no fixing tool for preventing overturning having an adhesive mat on the lower surface, which can be preferably attached to a support leg of an object to be fixed.

  When attaching a fall prevention fixture with an adhesive mat on the lower surface to the support leg of the object to be fixed, it is conceivable to drill a through hole in the support leg or hit an iron plate screw. This is not easy and may increase the installation cost of the fall-preventing fixing tool and damage the support leg of the fixed object.

  Also, in a clean room where airborne particulates are controlled below a certain level of cleanliness, it is necessary to avoid drilling through holes in the support legs of the fixed object or hitting steel plate screws or the like on the support legs. Don't be.

  In view of the circumstances as described above, the present invention provides a tipping-preventing fixture having an adhesive mat on its lower surface so that it can be attached to the supporting leg very easily without processing the supporting leg of the fixed object. It was made to provide a prevention fixture.

In order to solve the above-described problems, the present invention provides the following overturn prevention fixture.

In the fixing tool for preventing overturning having an adhesive mat on the lower surface of the support plate,
A support frame is erected on the upper surface of the support plate, and a bolt that penetrates the support frame inward and outward in the horizontal direction is threadably engaged with the support frame, and the tip of the bolt is covered with a pressing plate. The supporting leg is clamped between the pressing plate and the supporting frame by pressing the supporting leg of a fixed object,
The support frame is aligned with a fixed portion fixed to the upper surface of the support plate and a detachable portion that is detachably attached to the fixed portion, so that the fall prevention fixing tool is attached to the support leg of the fixed object. A fixing tool for preventing overturning, wherein the object to be fixed does not need to be lifted so that the lower end of the supporting leg is higher than the upper edge of the support frame.

Since the support leg of the object to be fixed is sandwiched between the pressing plate and the support frame, there is no need to perform a process such as making a through hole in the support leg or hitting an iron plate screw or the like. Therefore, the fixing tool for preventing overturning can be fixed to the supporting leg very easily and without damaging the supporting leg of the object to be fixed, and the mounting cost of the fixing tool for preventing overturning can be reduced.

Further, since it is not necessary to process the support legs of the object to be fixed, the fixing tool for preventing overturning can be attached to the support legs of the object to be fixed without any trouble even in the clean room.

  In addition, since the adhesive mat is provided in the lower surface of the support plate, it cannot be overemphasized that a horizontal support surface, such as the floor surface which fixes a to-be-fixed object, is not damaged.

When attaching rolling the debt prevention fixture support leg of the object to be fixed, the support plate between the horizontal support surface such as the lower end and the floor of said supporting legs once detached state removable portion of the support frame from the fixed portion After attaching the mounting / dismounting part to the fixing part, the tip of the bolt is pressed against the supporting leg of the fixed object via the pressing plate, so that the supporting leg is clamped between the pressing plate and the support frame. be able to. Therefore, it is not necessary to lift the object to be fixed so that the lower end of the support leg is higher than the upper edge of the support frame in order to put the support plate of the fall prevention fixing tool below the support leg.

  Also, when removing the fall prevention fixing tool from the support leg of the fixed object, the lower end of the support leg of the fixed object becomes higher than the upper edge of the support frame by removing the attaching / detaching part of the support frame from the fixing part. No need to lift.

  As described above, the attachment work and the removal work of the overturn prevention fixing tool with respect to the support leg of the fixed object are facilitated.

  What is shown by the code | symbol 1 is a support plate.

  An adhesive mat 3 is provided on the lower surface of the support plate 1. The adhesive mat 3 adheres to a horizontal support surface 5 such as a floor surface.

As an example, the adhesive mat 3 is a plate-like piece formed of gel-like ultrasoft urethane having adhesiveness.

  A support frame 7 is erected on the upper surface of the support plate 1. The support frame 7 has various shapes and the like according to the shape of the support leg 9 of the fixed object.

  The support legs 9 of the fixed object have, for example, shapes such as a cylindrical shape, a columnar shape, a substantially rectangular tube shape, and a substantially rectangular column shape.

  Bolts 11 that penetrate the support frame 7 inward and outward in the horizontal direction are screwed into the support frame 7 so as to be able to advance and retract. That is, a horizontal female screw 15 corresponding to the male screw 13 of the bolt 11 is formed in the support frame 7, and the male screw 13 of the bolt 11 is screwed into the female screw 15 of the support frame 7.

  By pressing the tip 11 a of the bolt 11 against the support leg 9 of the fixed object via the pressing plate 17, the supporting leg 9 is strongly held between the pressing plate 17 and the support frame 7.

  The pressing plate 17 has a shape corresponding to the support leg 9 of the fixed object.

For example, in the case of the cylindrical support leg 9, the pressing plate 17 has an arc shape (see FIGS. 1 to 4). Moreover, in the case of the substantially quadrangular prism-shaped or substantially rectangular tube-shaped support leg 9, the pressing plate 17 is substantially L-shaped (see FIG. 5).

In the example shown in FIGS. 1 to 3, the support frame 7 includes a fixing portion 7 a fixed to the upper surface of the support plate 1 and an attaching / detaching portion 7 b detachably attached to the fixing portion 7 a.

  That is, the detachable portion 7b is detachably attached to the fixed portion 7a by the bolts 19 and 19. In this case, the bolt 11 that penetrates the support frame 7 inward and outward in the horizontal direction is attached to the detachable portion 7b.

In the example shown in FIG. 5, a plurality of bolts 11, 11... That penetrate the support frame 7 inward and outward in different horizontal directions are screwed to the support frame 7 so as to freely advance and retract.
That is, the front ends of the plurality of bolts can be pressed against the support leg of the fixed object from different directions via the pressing plate. Therefore, even if the support leg of the fixed object is a substantially prismatic body, a substantially rectangular tube body, or the like, the support leg can be securely held between the pressing plate and the support frame.

  In the example shown in FIG. 5, the support leg 9 of the fixed object has a substantially quadrangular prism shape or a substantially rectangular tube shape, and the support frame 7 also has a substantially rectangular tube shape. Two bolts 11, 11 penetrating inward and outward in the horizontal direction through two adjacent sides 7 c, 7 d of the support frame 7 are threadably engaged with the support frame 7. The pressing plate 17 is substantially L-shaped.
