Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a washer for a screw used when connecting two members having screw pockets.

(Prior Art) For example, two members made of extruded aluminum profiles are connected to each other using bis pockets provided in the profiles. When connecting two parts so that the end face of the other member is in contact with the side surface of one member, the screw crosses the bis pocket of one member, penetrates that side surface, and enters the bis pocket from the end face of the other member. Screwed in like that.

By the way, when connecting one member and the other member that intersect at an angle other than a right angle, the screw comes into contact with the screw pocket of the one member at one point on the periphery of its head. However, considering that the tightening by the screw is transmitted to the screw pocket of the one member through the head of the screw, sufficient tightening force cannot be achieved in a fastening mode in which the screw and the one member contact only at one point. Therefore, the connection strength between the two members is small.

(Purpose) The purpose of the present invention is to connect two members by using a screw that crosses the bis pocket of one member and penetrates its side surface, enters the bis pocket from the end face of the other member, and extends in the axial direction of the other member. The objective is to ensure sufficient tightening force for both members.

(Structure) In order to connect two members having bis pockets, the present invention involves penetrating the side of one member from the inside of one member, crossing the bis pocket, and extending the bis pocket of the other member in its longitudinal direction. A washer for a screw, the screw head being in contact with a first side portion and a second side portion defining an opening edge of the screw insertion hole and an opening edge of the insertion hole. a first side portion having a circular arc surface and a second side portion capable of contacting the one member, the first side portions being spaced apart from each other in the circumferential direction of the circular arc surface; The opening edge on the first side extends in the circumferential direction of the arcuate surface, and the second side extends along the longitudinal direction of the bis pocket of the one member. has a semi-cylindrical surface which covers a part in the direction and can come into contact with the second part;
The opening edge on the side has a size that allows the screw to move along the opening edge on the first side.

(Operation and Effect) When the shaft of the screw is inserted into the insertion hole of the washer and screwed into both members in order to connect the two members, the head of the screw is inserted into the arcuate surface of the first side. It will touch at two points. Therefore, a larger tightening force can be applied to both members than in the conventional example in which the heads of the screws touch at only one point.
The opening edge on the first side of the washer extends in the circumferential direction of the arcuate surface, and the opening on the second side extends along the opening edge of the first side. Since it has a size that allows movement, the extension direction of the shaft portion of the screw is aligned with the extension direction of the other member, and two-point contact between the head of the screw and the first side portion is maintained. be able to.

Furthermore, since a plurality of small grooves are provided on the first side of the washer at intervals in the circumferential direction of the arcuate surface, when screwing in the screw, the head of the screw touches the first side. By crushing a portion of the screw, the head of the screw can be depressed into the first side. For crushing, the head of the screw and the first
Since the contact area with the side portion of the screw is increased and the head of the screw is prevented from moving in the circumferential direction of the arcuate surface, the screw and the washer can be brought into contact in a more stable state. . Furthermore, since the second side of the washer is provided with a semi-cylindrical surface that covers a part of the bis pocket of the one member in the longitudinal direction and can come into contact with the bis pocket, the washer and the one member can be connected to each other. can be brought into contact in a more stable state.

Therefore, according to the present invention, both members are tightened with a large force by the screw, and the screw,
The contact state between the washer and the one member can be stably maintained, and as a result, sufficient tightening force by the screw can be secured for both members.

(Embodiments) The features of the present invention will become clearer from the following description of the illustrated embodiments.

FIG. 1 shows a washer 10 according to the present invention.

The washer 10 has a first side 18 and a second side 20 that define a hole 12 for insertion of a fastener 26, which will be described later, and opening edges 14, 16 of the hole (see FIG. 2), respectively. It consists of a block with The block can be made of a metal material or a synthetic resin material such as nylon.

As shown in FIG. 2, the washer 10 of the present invention penetrates one member 22 to connect the two members 22 and 24, and the end surface 24a of the other member 22 is in contact with the side surface 22a of the other member 22. It is used for a fastener 26 consisting of a screw, bolt, etc. that extends in the longitudinal direction of the member 24.

The two members 22, 24 consist of extruded aluminum profiles. Both members are provided with bis pockets 22b and 24b extending in the axial direction, and when connected, the shaft portion 26b of the fastener (screw in this example)
diagonally crosses the bis pocket 22b of one member, passes through the side surface 22a, and is further screwed into the bis pocket 24b of the other member.

The block constituting the washer 10 has another pair of side parts 28 adjacent to the first and second side parts 18, 20, and another side part 30 adjacent to the first side part 18. a top portion 32 adjacent to the side and second side portions 20 and first and second side portions 18,2;
and a bottom portion 34 adjacent to 0. The washer 10 is
The second side portion 20 is placed in contact with one member 22 .

The first side portion 18 has an arcuate surface 18a that can be contacted by the head 26a of the fastener, and an inclined surface 18b connected to the arcuate surface. continues to the side portion 34. The arcuate surface 18a can be a convex surface projecting outward from the block, as in the illustrated example, or a concave surface (not shown) concave inwardly from the block. In either case, the head 26a of the fastener and the arcuate surface 18a come into contact at two points. Further, when connecting both members 22 and 24, the arcuate surface 18a or the inclined surface 18 of the head 26a of the fastener
In order to prevent slippage against b, the arcuate surface 18a
A plurality of parallel small grooves 36 (see FIG. 1) are provided on the inclined surface 18b.

When the head 26a of the fastener is positioned so as to abut the inclined surface 18b, the head 26a is placed in contact with the inclined surface 1.
Make surface contact with 8b. The inclined surface 18b is, for example, a second
As shown in the figure, the side surface 22a of the one member and
It can be set to form a 60 degree angle.
Note that the inclined surface 18b does not necessarily need to be provided. Instead of the inclined surface 18b, the arcuate surface 18a
It can be an arcuate surface (not shown) that has the same curvature as and is continuous with the arcuate surface.

In order to prevent the washer 10 from touching the bis pocket 22b of one member in an unstable state when the washer 10 is arranged, the second side portion 20 is provided with an axial direction of the one member 22, that is, a bis pocket 22b.
Concave semi-cylindrical surface 20a (first
(see Fig. 4 and Fig. 4). Semi-cylindrical surface 20a
For example, the diameter thereof may be approximately the same as the outer diameter of the bis pocket 22b, and the second side portion 20 may further be provided with a pair of flat surfaces 20b continuous to the semi-cylindrical surface 20a. As a result, when placing the washer 10, the semi-cylindrical surface 20a is aligned with the bis pocket 22.
The pair of flat surfaces 20b are in contact with the inner surface of one member 22, and the stability of the washer 10 is increased.

The opening edge 14 of the hole 12 has an elliptical shape extending in the circumferential direction from the arcuate surface 18a of the first side. The opening edge 14 having an oval shape has one end 14a in the long axis direction connected to the arcuate surface 18a and the side portion 30.
The other end 14b is located on the slope 18b (see FIG. 3). On the other hand,
The opening edge 16 in the second side 20 is substantially formed on a semi-cylindrical surface 20a, and has an oval shape shorter in length than the opening edge 14, as shown in FIG. The opening edge 14 and the opening edge 16 both have a width dimension that is smaller than the diameter of the fastener head 26a and slightly larger than the diameter of the shank 26b, and as viewed in FIG. One end in the longitudinal direction of the opening edge 14 is located at the same level as the one end 14a of the opening edge 14, and the other end of the opening edge 16 is located at a level approximately halfway between the one end and the other end of the opening edge 14. . That is, the hole 12 extends from the opening edge 14 toward the opening edge 16 so that its length in the long axis direction is halved. Note that the length of the opening edge 16 in the longitudinal direction is a size that allows movement of the fastener 26 along the opening edge 14,
It is determined in consideration of the diameter of the shaft portion 26b of the fastener and the length of the opening edge 14 in the longitudinal direction. The opening edge 16 may also have a circular shape as long as it is set to such a size. Further, the one end of the opening edge 16 and the one end of the opening edge 14 can be configured to be located at different levels instead of the illustrated example, and each opening edge can be formed into the oval shape. Alternatively, it may be an elongated rectangle.

By moving the fastener 26 inserted through the hole 12 along the opening edge 14, as shown in FIG. 2, the inclination angle of the shaft portion 26b can be changed. Thereby, the shaft portion 26b can be made parallel to the axis of the other member 24. In the illustrated example, the inclination angle can be changed in a range from 0 degrees to 60 degrees, and the state in which the screws 26 are arranged at each of the inclination angles of 0 degrees and 60 degrees is shown by dashed lines.
Therefore, in this case, even if the two members 22 and 24 intersect at any angle α from 30 degrees to 90 degrees, the head 26a of the fastener is brought into contact with the arcuate surface 18 at two points, and the axis The portion 26b can be parallel to the axis of the other member 24. However, when the angle α is 30 degrees, the head 26a can be positioned on the inclined surface 18b, so that the head 26a and the inclined surface 18b come into surface contact.

In particular, when the angle α is in the range of 90 degrees to 150 degrees, the washer 10 may be used by inverting it so that the top portion 32 is positioned downward and the bottom portion 34 is positioned upward as shown in FIG. Thus, the head 26a can be brought into contact with the arcuate surface 18a at two points, and the shaft portion 26b can be made parallel to the axis of the other member 24.

The inclination angle of the shaft portion 26b of the fastener can be increased by setting the arcuate surface 18a and the opening edges 14, 16 to a further extended size.
