[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a washer temporary fixing device capable of temporarily fixing a washer to be used in the case of fastening a bolt to a nut with a bolt at a fastening operation.

[0002]

[Prior art]

Conventionally, in the case of suspending and fixing an outdoor unit of an air conditioner or other equipment to a ceiling or other high places during construction work, equipment work, etc., as shown in FIG. The nuts N ₁ and N from above and below on the bolt B axis are aligned by matching the groove m ′ of the mounting portion m projecting to the side of the mounting device M with the bolt B that is vertically fixed using _A mounting method is widely adopted in which washers W ₁ and W ₂ are used for fastening with _two .

However, in the work of suspending and fixing the equipment at such a high place, in FIG. 4, the first nut N ₁ is screwed into the bolt B in advance, and then the first washer W ₁ and And the second washer W ₂ are loosely engaged, and then the second nut N ₂ is screwed. Then, since the first nut N ₁ and the second nut N ₂ are screwed in advance with each other at an appropriate vertical interval, the first washer W ₁ has its own weight and thus the shaft portion of the bolt B. Is slid down and positioned on the second nut N _{2 in} a state of overlapping with the second washer W ₂ .

Therefore, the operator has to make a space between the first washer W ₁ and the second washer W ₂ so as to form a space for inserting the mounting portion m of the attachment device M. The washer W ₁ must be picked up by fingers and lifted. Since such a lifting of the washer W ₁ is performed while the worker supports the weight of the mounting device M at a high place where he / she climbs on a stepladder, a scaffold, etc., it is extremely cumbersome, troublesome, poor in workability, and dangerous. It was a thing.

[0006]

[Problems to be solved by the device]

 The present invention has been devised to eliminate the above-mentioned conventional problems.When the equipment is suspended and fixed, the bolts that are vertically fixed to the ceiling or other high places are fixed to the nuts. It is an object of the present invention to provide a temporary washer stopper that can be temporarily temporarily fixed to an arbitrary position on a bolt without sliding down the washer that has been loosely attached to it.

[0007]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The washer temporary stopper 1 according to the present invention is made of an elastic material such as rubber or soft synthetic resin. The elastic sheet 2 is characterized in that bolt through holes 3, 5 each having a circular hole shape, an elongated hole shape or the like are formed in the central portion of the elastic sheet 2 so that all or a part of the inner peripheral edge thereof is elastically contacted with the bolt B. To do.

[0008]

[Action]

 The temporary stopper 1 of the washer of the present invention having the above-described structure has bolts B 3 which are vertically fixed to the ceiling or other high places in the bolt through holes 3 and 5 formed in the central portion of the elastic sheet 2. When the bolts are forcibly penetrated, the entire or part of the inner peripheral edges of the bolt through holes 3 and 5 are appropriately elastically deformed to elastically contact the bolt B, and the frictional force generated at that time causes the bolt B to move to the desired position. Can be elastically locked.

Therefore, the temporary stopper 1 of the washer of the present invention is forcibly penetrated under the washer W ₁ loosely engaged with the bolt B, and the temporary stopper 1 is locked at an arbitrary position of the bolt B. For example, the temporary fixing tool 1 can be temporarily fixed to an arbitrary position of the bolt B while receiving the washer W ₁ .

【Example】

 The present invention will now be described with reference to the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a washer temporary stopper according to the present invention, which is made of an elastic material such as rubber or soft synthetic resin and has a thickness of 0.5 to 1 mm. A circular hole-shaped bolt through hole 3 is formed at the center of the elastic sheet 2 having a circular shape, a triangular shape, a quadrangular shape, a polygonal shape, or any other shape.

The bolt through hole 3 having a circular hole shape is set to have an inner diameter slightly smaller than the outer diameter of the bolt B which is vertically fixed to the corresponding ceiling or other high places. When the diameter is 9.52 mm, the inner diameter of the bolt through hole 3 is more than 0.92 mm, which is about 0. The size is set to be smaller by about 4 to 2 mm. Further, a cut 4 may be provided at an arbitrary position on the periphery of the bolt through hole 3.

The method of using the temporary stopper 1 configured as described above will be described. As shown in FIG. 2, the first nut N ₁ is attached to the bolt B vertically fixed to a ceiling or other high place. After the first washer W ₁ is loosely engaged after being screwed, the provisional fastener 1 is forcibly penetrated through the elongated bolt through hole 3, and the bolt through hole 3 is appropriately opened. Is elastically deformed to elastically contact with the bolt B over the entire inner peripheral edge thereof, and the temporary stopper 1 can be elastically contacted and locked at an arbitrary position of the bolt B by a frictional force. It can be temporarily fixed while W ₁ is received at an arbitrary position of the bolt B.

Thereafter, when the second washer W ₂ is loosely engaged with the bolt B and the second nut N ₂ is screwed with the bolt B at an appropriate interval, the first nut on the shaft of the bolt B A space for inserting the mounting portion m of the device M between the washer W ₁ and the second washer W ₂ can be formed in advance.

Therefore, the operator can very easily insert the mounting portion m of the device M between the first washer W ₁ and the second washer W ₂ which are formed with a required space in advance, and the bolt B Can be matched.

Then, on the bolt B, a state in which the first washer W ₁ , the temporary stopper 1 and the second washer W ₂ are interposed by both the first nut N ₁ and the second nut N _2. The mounting portion m of the device M can be fastened and fixed to the bolt B with.

As shown in FIG. 2, if the temporary stopper 1'is also used on the second washer W ₂ on the bolt B, the temporary stoppers 1 and 1 are provided above and below the mounting portion M'of the device M. 'Is intervened, and the anti-vibration effect can be exerted. In this case, if unevenness is formed on the surface or both front and back surfaces of the temporary fasteners 1 and 1 ', a further anti-vibration effect can be expected.

FIG. 3 shows another embodiment of the temporary fastener 1. The temporary fastener 1 has a long hole-shaped bolt through hole 5 formed in the central portion of the elastic sheet 2. The hole-shaped bolt through hole 3 is dimensioned such that its major axis is larger than the outer diameter of the bolt B and its minor diameter is smaller than the outer diameter of the bolt B. Therefore, when the outer diameter of the bolt B is 9.52 mm, the bolt through hole 3 is formed in a long hole shape having a major axis larger than 9.52 mm and a minor axis smaller than 9.52 mm. .

In this way, when the bolt through hole 5 of the temporary fastener 1 is formed in a long hole shape, the bolt through hole 5 is elastically deformed and a part of the inner peripheral edge, which is the minor axis direction thereof, becomes the bolt B. The washer W ₁ can be temporarily fixed to an arbitrary position of the bolt B by elastically engaging and locking it.

When the bolt through hole 5 of the temporary fastener 1 is formed in a long hole shape in this manner, there is an advantage that the forced through work of the bolt through hole 4 with respect to the bolt B can be performed smoothly and easily.
