Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to the improvement of wedges.

[Conventional technology]

Traditionally, wedges have been formed to have a so-called V-shaped side surface.

Therefore, while the proximal end of the wide width can be easily driven into a predetermined position by a hammer blow, etc., it can also be driven into a predetermined position not only by a light impact on the tip but also by a light shock such as vibration acting on the wedge. It has the disadvantage of being easily removed from its position.

Therefore, an improved wedge as shown in FIG. 3 can be proposed.

That is, the wedge is formed so that the extension line of one side edge 1 and the extension line of the other side edge 2 are V-shaped, like the conventional wedge, but one side edge 1 has a An inclined edge 3 is formed in substantially the same direction as the extension line of the edge 2.

As a result, when the wedge is press-fitted, for example, into the insertion hole a of one member A and the insertion hole b of the other member B, which are stacked in the vertical direction, the other side edge 2 will fit into the inner edge b1 of the insertion hole b. In response to the pressing, the inclined edge 3 is pressed against the inner edge a1 of the insertion hole a, and while fixedly connecting each member A and B, it acts on each member A and B or the wedge. This means that it will not come off easily due to vibrations, etc.

[The problem that the idea attempts to solve]

However, the wedge according to the above proposal does not come off easily due to vibrations acting on each member A, B or the wedge, so a considerably large impact force must be applied to the tip of the wedge. This cannot be removed.

As a result, there is a risk that the impact force from the hammer or the like will be excessive and the wedge will fly out with great force, posing a danger of colliding with the worker or the like.

In addition, since large forces are repeatedly applied to the tip of the wedge by hammer blows, etc.,
It is necessary not only to take measures to reinforce the point, but also to make it easier to hit with a hammer or the like.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to prevent it from popping out when hit by a hammer, etc., and to make it possible to reinforce the tip part, and To provide a wedge that is easy to perform hammer blows, etc.

[Means to solve the problem]

In order to achieve the above object, the configuration of this invention is such that the extension line of one side edge and the extension line of the other side edge are V.
In a wedge that is formed to have a letter shape and has an inclined edge on one side edge set to be in the same direction or approximately the same direction as the extension line direction of the other side edge, the base end portion At the same time, a pointed end portion serving as a hammer striking portion is bent toward the other side edge, and a through hole is bored in the pointed end portion to enable a rivet or the like to be connected thereto.

Preferably, the base end portion of the wedge is bent toward one side edge, and if necessary, a flange portion is formed at the base end portion of the wedge.

[Effect]

Therefore, by connecting a bolt, rivet, etc. to the tip of the wedge that is inserted into the insertion hole for inserting the wedge, the rivet, etc. becomes a so-called stopper, and the wedge is inserted into the insertion hole. This means that it is possible to prevent the child from escaping from the situation, that is, from jumping out.

When drilling a through hole in the tip for connecting a rivet, etc., the tip is made into a curved and wide part by considering the location of the hole, which makes it possible to strengthen the tip. At the same time, it makes it easier to perform hammer blows, etc.

〔Example〕

This invention will be explained in detail below based on the illustrated embodiment. The wedge according to this invention is formed as shown in FIG. 1 and used as shown in FIG. 2.

That is, the wedge according to this invention is formed to have one side edge 1, the other side edge 2, and an inclined edge 3, as shown in FIG.

The side edges 1 and 2 are set so that their extension lines intersect below the tip of the wedge (lower end in the figure), giving the side surface a V-shape.

The inclined edge 3 is one side edge 1 on the right side in the figure.
It is formed with a concave cutout on the tip side, which is the lower half of the tip.

As shown in the figure, in this embodiment, the direction in which the inclined edge 3 extends is set to be the same as the direction in which the other side edge 2 extends.

Note that, instead of the above, the direction of the extension of the inclined edge 3 may be substantially the same as the direction of the extension of the other side edge 2. In this case, the extension of the inclined edge 3 may be in the same direction as the extension of the other side edge 2. Of course, it intersects the extension line of the edge 1 on the upper side or the lower side.

Furthermore, in this embodiment, not only the other side edge 2 and the inclined edge 3 but also the base end side of the one side edge 1 above the inclined edge 3 are used as a so-called locking edge. (See Figure 2).

As mentioned above, the wedge according to this invention is, in principle, configured to have an inclined edge 3 on one side edge 1, but the following considerations have been made in this invention. .

That is, a flange portion 4 is formed at the proximal end (upper end in the figure) of the wedge to reinforce the proximal end and to make it easier to hit the proximal end with a hammer or the like.

Further, as shown in the figure, in this embodiment, the base end portion of the wedge is bent toward one side edge 1 to make it easier to perform hammer blows on the flange portion 4, etc.

It should be noted that the shape of the proximal end portion is not limited to the above-described shape and may of course be made in other forms as long as the proximal end portion of the wedge can be easily hammered or hit.

On the other hand, a through hole 5 for inserting bolts, rivets, etc. is bored in the tip of the wedge, and after that,
By continuously installing a rivet or the like 6 in the through hole 5,
This makes it possible to prevent the wedge from falling out, which could lead to loss or falling off.

Incidentally, instead of the rivet or the like 6, a flexible member such as a chain or wire may be connected to the through hole 5.

By the way, when drilling the above-mentioned through hole 5, rather than setting the drilling position on the axis of the wedge shown by the imaginary line in the figure, it is necessary to take into account the use of the wedge (see Fig. 2). In this case, it is preferable to be eccentric from the above-mentioned axis line position.

Therefore, if the through hole 5 is provided at a position eccentric from the axial position of the wedge, for example, as shown in the figure, the through hole 5 will be close to the extension line position of the other side edge 2. This makes it difficult to ensure that the sharpness of the blade is strong, and the durability of the pointed end against hammer blows and the like is also reduced.

Therefore, in this invention, the tip of the wedge is bent toward the other side edge 2 to form a wide so-called nose curve, and the through hole 5 is close to the extension line position of the other side edge 2. Even if the hole 5 is to be drilled at the tip, the hole 5 is provided at the center of the tip, which makes it possible to reliably open the hole 5 and to protect the tip from being hit by a hammer or the like. The setting is to prevent a decrease in durability.

Since the tip of the wedge is bent into a so-called nose-bent state, the operability when hitting the tip with a hammer or the like is also improved.

As shown in Fig. 2, the wedge formed as described above is a pillar 10 vertically erected on the ground surface, etc.
It is used to fixedly connect the connecting members 20 disposed horizontally to the connecting member 20 .

That is, the pillar material 10 holds a flange portion 11, and the wedge is inserted into an insertion hole 12 formed in the flange portion 11.

The column 10 has a screw jack 14 having a base plate 13 at its lower end, and a joint 15 at its upper end.

On the other hand, the connecting member 20 has a connecting part 21 connected to its end, and the wedge is inserted into upper and lower insertion holes 22 and 23 formed in the connecting part 21.

Although the connecting member 20 is a so-called lateral member disposed in the horizontal direction, it is of course possible to use a diagonal member such as a brace instead of this. .

It goes without saying that the insertion hole 12 of the flange portion 11 and the insertion holes 22 and 23 of the connection portion 21 have sufficient length and width dimensions to allow insertion of the wedge. In this example,
The widthwise dimension of the insertion hole 22 on the upper side of the connecting portion 21 is formed to be smaller than the axial length of the rivet etc. 6 connected to the tip of the wedge.

As a result, when the wedge is pulled out from the insertion hole 12 of the flange portion 11, that is, when the connection between the pillar member 10 and the connecting member 20 is released,
As shown in the imaginary diagram in the figure, the wedge is held in the insertion hole 22 of the connecting portion 21, making it possible to prevent the wedge from popping out, falling off, or being lost.

The above-mentioned wedge is connected to each of the above-mentioned insertion holes 22, 12, 23.
By applying a striking force to the flange portion 4 so as to insert it therethrough, the flange portion 4 is press-fitted into each of the insertion holes 22, 12, and 23.

At this time, one side edge 1 of the wedge is brought into contact with the inner edge 22a of the insertion hole 22, and the other side edge 2 is brought into contact with the insertion hole 1.
2, and the inclined edge 3
comes into contact with the inner edge 23a of the insertion hole 23.

As a result, the pillar 10 and the connecting member 20 are attracted to each other, and the connecting part 21 of the connecting member 20 is brought into contact with the outer periphery of the pillar 10, so that mutual displacement is regulated. The pillar member 10 and the connecting member 20 are fixedly connected.

Then, insert the wedge into the insertion hole 2 as described above.
2, 12, and 23, even if an external force is applied to pull out the wedge upward, the inclined edge 3 will not fit into the inner edge 2 of the insertion hole 23.
This means that it will be further pressed against 3a and will not come out easily.

Therefore, for example, the pillar material 10 or the connecting material 20
Even if inertia is applied to the wedge due to vibration in the vertical direction, the wedge will not easily come out from the press-fitted part due to the vibration, and both members will be A fixed connection of 10, 20 will be easily maintained.

In order to remove the wedge and release the fixed connection state, it is sufficient to hit the tip of the wedge with a relatively large impact force using an appropriate tool such as a hammer.

At that time, the tip of the wedge is bent toward the front in a wide, so-called nose-bent state.
The impact with the hammer or the like can be easily and reliably performed.

Further, since the tip portion is in a so-called reinforced form, even if the hammer or the like is repeatedly hit, the tip portion will not be deformed or other inconveniences.

[Effect of idea]

As described above, according to this invention, the extension line of one side edge and the extension line of the other side edge are formed in a V-shape, and the extension line of one side edge is in the same direction as the extension line of the other side edge. In a wedge formed with inclined edges set to be in the same direction or in substantially the same direction, the pointed end portion, which serves as the hammer striking portion together with the base end portion, is bent toward the other side edge, and the pointed end portion is bent toward the other side edge. Since a through hole is drilled to enable the continuous installation of rivets, etc., it is possible to effectively prevent the wedge from coming out of its predetermined position due to vibrations acting on the wedge, etc. press-fitted in a predetermined position. Of course, this can be prevented by attaching a bolt, rivet, etc. to the tip of the wedge that is inserted into the insertion hole for inserting the wedge, so that the rivet, etc. becomes a so-called stopper. This makes it possible to prevent the wedge from coming out of the insertion hole, that is, from popping out.

According to this invention, when providing a through-hole through which a rivet or the like is inserted in the tip, the tip is bent into a wide so-called curved nose shape, taking into account the position at which the hole is drilled. This makes it possible to reinforce the tip portion against hammer blows and the like.

Furthermore, when a flange is formed at the base end of the wedge to strengthen it, and when the base end is bent toward one side edge, it becomes easier to perform hammer blows on the flange, thereby improving operability. is further improved.
