Abstract

<P>PROBLEM TO BE SOLVED: To provide a vacuum anchor as a device to be used more safely while a temporary installation such as a sign board is sucked and fixed to the ground surface or wall surface by using vacuum suction. <P>SOLUTION: A temporary installation fixing device has a vacuum pump 1 to generate a vacuum and a vacuum pad 3 furnished with a rubber pad 11 contacting with the ground surface or wall surface 5 made of concrete etc. as the member to be connected, whereby suction and fixation are performed by making vacuum the space between the rubber pad 11 and the ground surface or wall surface 5, and after the service, the outside air is drawn in for separation by shutting off the power to the vacuum pump 1 for opening a vacuum removal valve 9. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a temporary object fixing device using vacuum suction.

  Conventional fixtures such as signboards when placed on the ground are of a size that prevents weights such as sandbags from moving. Or, it was fixed firmly with foundation bolts or tied to a non-moving object such as a pillar. Moreover, when attaching to a wall surface, it had to be drilled and fixed with bolts. Therefore, when a simple method is used, it may move due to wind and rain.

  The present invention prevents a temporary object placed on the ground or a temporary object fixed to a wall surface from moving as described above, and performs installation / removal by a simple operation.

The vacuum anchor of the present invention that solves the above problems is a fixing device that uses vacuum to adsorb the ground or wall surface and fixes a temporary object that is not permanently fixed, and is equipped with an air filter for preventing foreign matter from entering The first feature is that a vacuum device connecting hose that connects a vacuum pump that generates a vacuum, a vacuum pad, and a vacuum pad body of about 500 mm × 250 mm are provided. A vacuum pad is made of soft rubber on the outer circumference of the bottom surface of the vacuum pad, and a hole is made in the plate. A vacuum release valve for separating the pad and the ground, a vacuum gauge for confirming the degree of vacuum, and a fixing knob for fixing a thin plate previously attached to the temporary structure to the vacuum pad are provided.
In addition to the first feature described above, the vacuum anchor of the present invention has a fine mesh-like stainless steel filter net to prevent excessive dust from being sucked into the pad rubber, and the pad rubber shrinks more than necessary. A second feature is that a stopper is provided to prevent this.

The present invention has the above-described configuration and operation. According to the vacuum anchor according to claim 1, the vacuum anchor is used to fix the ground or a wall surface and a temporary object such as a sign board. A vacuum pump that generates at least a vacuum, a vacuum device connection hose that connects the vacuum pump and the vacuum pad, and a plate-like vacuum pad body, and the vacuum pad is made of soft rubber on the entire outer periphery of the lower surface thereof The finished pad rubber is attached, and the vacuum device connection fitting to be connected to the vacuum device connection hose on the upper surface, the vacuum release valve for drawing the outside air and separating the vacuum pad from the ground or the wall surface, and for checking the degree of vacuum A vacuum gauge and a fixing knob for fixing the thin plate pre-attached to the temporary structure to the vacuum pad are provided. Tsu can only be installed and removal is easy in opening and closing the switch operation and a vacuum withdrawal valve, weight etc. massive foundation bolts and sandbags as in the prior art also becomes unnecessary.
Further, according to the vacuum anchor according to claim 2, in addition to the effect of the configuration according to claim 1, the stainless steel has a fine mesh shape for preventing excessive dust from being sucked into the pad rubber inside the vacuum pad lower surface. A filter net made of metal and a stopper that prevents the pad rubber from shrinking more than necessary when adsorbing are provided, reducing the breakdown of the device due to contamination and the consumption of the pad rubber made of soft rubber.
In addition to the sign board, it can be used for ladders, temporary scaffolding, temporary house foundations, event tent foundations, temporary traffic lights, and the like.

Embodiments of the present invention will be further described with reference to the following drawings.
First, referring to FIG. 1 and FIG. 2, a temporary object 4 such as a sign board is placed on a vacuum pad 3 made of an aluminum plate of about 500 mm × 250 mm and attached to the lower part of the temporary object in advance. A thin plate with two holes is aligned with the hole of the vacuum pad 3. Two holes are fixed with two temporary object pad fixing knobs having a diameter of about 5 cm. The vacuum pump 1 to which the air filter 2 is attached and the vacuum pad 3 are connected by a vacuum device connection hose 14, and the vacuum pump 1 is turned on.

  3 and 4, the pad rubber 11 made of soft rubber and attached to the entire circumference of the lower surface of the vacuum pad 3 from the vacuum pump 1 through the vacuum device connection fitting 8 and the ground or wall surface 5 The space between them is evacuated. The adsorption force is about 4500N. As the pad rubber 11 contracts, the unevenness of the ground surface or the wall surface 5 can be absorbed. At that time, a stopper 13 is provided so that the pad rubber 11 does not shrink more than necessary. A fine mesh-like stainless steel filter net 12 is also provided on the lower surface of the vacuum pad 3 so that dust in the space does not enter the tube. The pressure can be confirmed with a vacuum gauge 7 on the upper surface of the vacuum pad. At the time of detachment, the vacuum pump is turned off and the vacuum release valve 9 attached to the upper surface of the vacuum pad is opened to draw outside air and release it. A handle 10 is used to facilitate carrying.

It is a front view showing the outline of the vacuum anchor concerning the embodiment of the present invention. It is a right view which shows the outline of a temporary structure and a vacuum pad. It is a top view of a vacuum pad part. It is a front view of a vacuum pad part.
