Description

The present invention relates to containers with lids.

BACKGROUND ART Containers with lids that can open a pair of lids by applying a predetermined force to a pedal have been known. For example, Patent Document 1 discloses a garbage container, a pair of lids that are attached to the upper opening of the garbage container so that they can be opened and closed on both sides, a pedal part that is attached to the garbage container and receives force, and a pedal part that is attached to the garbage container and receives force. Disclosed is a trash can having a connecting body that connects a lid and a pair of lids.

Each of the pair of lids includes a lid body and an engagement member for attaching the lid body to the garbage storage container body so that the lid body can rotate between a closed state and an open state about a rotation axis extending in the front-rear direction. It has a locking protrusion and a locking hole formed on the back side of the lid body so as to open in the front-rear direction.

The locking hole is provided at a position horizontally apart from the locking convex portion over a rotation range between the closed state and the open state of the lid body.

The connecting body includes a vertical portion that moves upward in response to a force received by the pedal portion, and a vertical portion provided at a position horizontally away from the locking convex portion so as to move in conjunction with the movement of the vertical portion. and a cylindrical locking rod portion extending in the front-rear direction so as to be inserted into each of the locking holes.

In the trash can according to Patent Document 1, the vertical portion moves upward when the pedal portion receives force, and the locking round bar inserted into the locking hole moves upward in conjunction with the movement of the vertical portion. do. As a result, the locking round bar comes into contact with the downward area (hereinafter referred to as the downward area) on the inner surface of the locking hole, and by pushing up the downward area, the lid is opened around the locking protrusion. Rotate.

JP2019-085241A

Here, the locking hole is provided at a position horizontally apart from the locking protrusion (rotation center) over a rotation range between the closed state and the open state of the lid body. Therefore, in the process in which the locking round bar part pushes up the downward area of the locking hole, the locking round bar part and the downward area of the locking hole relatively slide in the horizontal direction. Furthermore, in order to effectively utilize the upward force from the locking round bar during horizontal sliding, the downward area of the locking hole is connected to the locking round bar that moves in the horizontal direction. It is necessary to have a surface for contacting at an angle as close to perpendicular to the surface as possible. Therefore, the inner surface of the locking hole, which rotates around the locking protrusion by itself, has a complicated shape that is curved as a downward region.

As described above, since the inner surface of the locking hole has a complicated downward area, if the locking round bar part moves upward rapidly due to forceful stepping on the pedal part, the locking round bar part has a complicated downward area. The sliding resistance between the rod portion and the inner circumferential surface of the locking hole becomes large, and there is a possibility that the lid cannot be opened smoothly.

An object of the present invention is to provide a container with a lid that allows a pair of lid parts to be opened smoothly.

In order to solve the above problems, the present invention provides a container with a lid, which includes a container main body having an opening that opens upward, and a closure that closes the opening around a rotation axis extending in a predetermined axial direction. a pair of lids attached to the container body in a double-openable state so as to be rotatable between a posture and an opening posture for opening the opening; an operated part that receives a force for opening the pair of lid parts; a moving part connected to the operated part so that the operated part can move upward in response to the force; and a pair of connecting mechanisms that connect the lid portion and the pair of lid portions, and the connecting mechanism is configured to rotate from the rotation axis over a rotation range between the closed position and the open position of the lid portion. A rotating part provided on the lid part in a state that is spaced apart in a horizontal direction in an orthogonal direction perpendicular to the axial direction and extending in the axial direction; a pushing-up surface provided on the moving part to be able to push up the rotating part so that the rotating part is rotated to the open position, and the rotating part is configured to push up the rotating part of the lid part. The pushing-up surface has an outer circumferential surface such that a portion facing the pushing-up surface is an arcuate surface over a rotation range, and the pushing-up surface is arranged such that the rotating section Provided is a container with a lid that extends along the orthogonal direction so as to allow sliding in the orthogonal direction with respect to the pushing surface.

In the present invention, the rotating portion extending in the axial direction is provided at a position perpendicularly away from the rotation axis over the rotation range between the closed position and the open position. Further, the rotating portion has an outer circumferential surface such that a portion facing the pushing-up surface is an arcuate surface over the rotating range of the lid portion. Therefore, in the process of the pushing-up surface pushing up the rotating part (the process in which the rotating part and the pushing-up surface relatively slide in orthogonal directions), the downwardly facing area of the rotating part is centered around the rotating axis. It is a circular arc regardless of the rotation position in the orthogonal direction of the rotating part. Therefore, in the present invention, it is possible to simply form the shape of the pushing-up surface for contacting the rotating part that moves in a relative orthogonal direction at an angle as close to perpendicular as possible. Specifically, in the present invention, the pushing-up surface is formed in a shape along the orthogonal direction. As a result, it is possible to suppress the sliding resistance between the rotating part and the pushing-up surface from increasing, so that the pushing-up surface can be prevented from rapidly moving upward due to the operated part being stepped on forcefully, etc. The pair of lids can be opened smoothly.

In the container with a lid, it is preferable that the pushing-up surface is provided on the moving part so as to come into contact with a lower end part of the rotating part when the lid part is in the closed position.

According to this configuration, the force for rotating the lid to the open position can be quickly released from the push-up surface compared to the case where the lower end of the rotating part is away from the push-up surface when the lid is in the closed position. It can be transmitted to the lower end of the moving part. Therefore, according to the configuration, the lid can be opened quickly.

In the container with a lid, the rotating part is provided on the lid so as to be located below the rotating shaft when the lid is in the closed position, and the pushing-up surface In the initial rotation stage when the rotation from the closed position to the open position is started, a component of the force of the pushing surface pushing up the rotating part passes through the center of the rotating shaft and the center of the rotating part. a first push-up portion that is inclined with respect to the orthogonal direction in a direction that increases in the tangential direction of the pivoting portion perpendicular to the straight line; and a subsequent pivoting step that follows the initial pivoting step in the opening operation of the lid. In order to push up the rotating part, it is preferable to have a second push-up part extending in the orthogonal direction from the first push-up part.

According to this configuration, since the rotating part is located below the rotating shaft, the rotating part and the coupling mechanism for pushing it up can be housed under the lid part to prevent the container with a lid from becoming bulky. I can do it. However, when pushing up the rotating part located below the rotating shaft on a horizontal plane, it is difficult to obtain a sufficient force in the direction to rotate the rotating part about the rotating shaft. Therefore, in the above configuration, the push-up surface has a first push-up portion that is inclined in a direction more advantageous than the horizontal plane with respect to obtaining a force for pivoting the lid part to the open position in the initial rotation stage. Therefore, the force required to rotate the lid to the open position at the initial rotation stage can be reduced compared to the case where the rotating part is pushed up by the first push-up part extending parallel to the orthogonal direction. can. Moreover, since the pushing-up surface has a second pushing-up portion extending in a direction orthogonal to the first pushing-up portion, it is possible to efficiently transmit upward force for pushing up the rotating portion in the subsequent rotation stage.

In the container with a lid, the moving part is connected to the operated part so as to be movable downward in response to the release of the force acting on the operated part, and the connection mechanism includes: The moving part is provided so that the rotating part can be pushed down so that the lid part is rotated to the closed position in response to the moving part moving downward, and the lid part It is preferable that the rotating part has a push-down surface extending along the orthogonal direction so as to allow the rotating part to slide in the orthogonal direction during the process of rotating to the closed position.

According to this configuration, by releasing the force acting on the operated portion and moving the push-down surface downward, the rotating portion can be pushed down in the direction in which the lid portion rotates to the closed position. Therefore, by releasing the force acting on the operated portion, rotation of the lid portion to the closed position can be assisted.

Further, in the above configuration, the pressing down surface extends along the orthogonal direction. Thereby, it is possible to suppress the sliding resistance between the rotating part and the push-down surface from increasing, so that the pair of lid parts can be closed smoothly.

In the container with a lid, the rotation range includes a closable region in which the lid can be closed as the pressing surface moves downward when the force on the operated section is released; a difficult-to-close region in which it is difficult to close the lid due to the downward movement of the pressing surface due to the release of the force on the container body; It is preferable to have a restriction part that comes into contact with the lid part in order to restrict rotation beyond the area to the difficult-to-close area.

According to this configuration, since the restriction part restricts the lid from rotating beyond the closable area, the lid can be moved by releasing the force acting on the operated part and moving the push-down surface downward. can be rotated into a closed position.

In the lidded container, the rotating part is provided on the lid so as to be located below the rotating shaft in the closed position, and the pushing-up surface is configured to move the lid from the closed position to the lid. In the initial rotation stage when the rotation towards the open position is started, a component of the force of the pushing-up surface pushing up the rotation part is perpendicular to a straight line passing through the center of the rotation axis and the center of the rotation part. It has a first push-up portion that is inclined with respect to the orthogonal direction in a direction that increases in the tangential direction of the intersecting rotating parts, and the rotating range is between the center of the rotating shaft and the center of the rotating part. and the distance in the orthogonal direction is set to match in the initial rotation stage and in the final rotation stage immediately before the lid comes into contact with the restriction part in the opening operation of the lid. It is preferable.

According to this configuration, the distance between the center of the rotation axis and the center of the rotation part in the orthogonal direction is the same in the initial rotation stage and the final rotation stage. Furthermore, in the initial rotation stage, the rotating part is located below the rotation axis. Therefore, in this final pivoting stage, the first push-up portion does not function effectively in obtaining the tangential force component of the pivoting part. That is, in the final rotation stage, the force for rotating the lid can be kept small, so that when the lid comes into contact with the regulating part, the load on the lid and the regulating part can be kept small.

In the container with a lid, the connection mechanism is provided in the moving part so as to connect one end of the pushing-up surface in the orthogonal direction and one end of the pushing-down surface in the orthogonal direction. a second side surface provided on the moving part so as to connect the first side surface, the other end of the pushing-up surface in the orthogonal direction, and the other end of the pushing-down surface in the orthogonal direction; , the first side surface has a first connecting portion connected at an obtuse angle to the pushing-up surface, and a second connecting portion connected at an obtuse angle to the pushing-down surface. and the second side surface has a third connection part connected at an obtuse angle to the push-up surface and a fourth connection part connected at an obtuse angle to the push-down surface. is preferred.

According to this configuration, since the push-up surface and the push-down surface are connected to each other by the two side surfaces, the relative positions of the push-up surface and the push-down surface can be reliably maintained. On the other hand, when the pushing up surface and pushing down surface and both side surfaces are connected perpendicularly, there is a possibility that stress is concentrated at the connecting portion between the pushing up surface and pushing down surface and both side surfaces during pushing up and pushing down. On the other hand, in the above configuration, the pushing up surface, pushing down surface, and both side surfaces are connected at an obtuse angle by the first connecting section, the second connecting section, the third connecting section, and the fourth connecting section, which alleviates stress concentration. can do.

According to the present invention, it is possible to provide a container with a lid whose pair of lid parts can be opened smoothly.

It has a lid opening/closing mechanism 60.

As shown in FIGS. 1 to 7, the container body 10 is a bottomed container having an opening 19A that opens upward. Specifically, the container body 10 includes a bottom plate 11 and a peripheral wall erected on the periphery of the bottom plate 11. The peripheral wall includes a front plate 14 extending in the +Z direction from the end of the bottom plate 11 in the −Y direction, a rear plate 16 extending in the +Z direction from the end of the bottom plate 11 in the +Y direction, and both ends of the bottom plate 11 in the X direction.

A regulating section 25 is provided for regulating. Details of the regulating section 25 will be described later.

As shown in FIGS. 1 to 7, the lid 30 has a closed position (see FIG. 1) in which the opening 19A is closed around a rotation axis (not shown) extending in the Y direction, and an open position in which the opening 19A is opened. It is attached to the container main body 10 in such a manner that it can be opened in both directions so as to be rotatable between the two positions (see FIG. 2). Note that the pair of lids 30 are arranged side by side in the X direction and have a symmetrical configuration in the X direction with respect to the center line in the X direction when viewing the lidded container 1 in the +Y direction. The structure of only the lid part 30 on the -X direction side of the lid parts 30 will be explained.

In the rotation range between the closed position and the open position of the lid part 30, the lid part 30 is closed due to the downward movement of the push-down surface 120, which will be described later, due to the release of the force on the operated part 70, which will be described later. It includes a possible closable area and a difficult-to-close area where it is difficult to close the lid part 30 due to the downward movement of the push-down surface 120 due to the release of the force on the operated part 70. In the present embodiment, the rotation of the lid 30 beyond the closable region to the non-closable region is restricted by a regulating portion 25, which will be described later, and the opening operation of the lid is restricted at the position shown in FIG. That is, the rotation range includes a predetermined opening range in which the lid portion 30 is in an open position, and this opening range is set to cover a closable area and a difficult-to-close area.

The operated part main body 71 is arranged in the operated part accommodation groove 12 provided on the end face in the Z direction, and the -Y direction side opening 15 of the operated part accommodation groove 12 formed in the front plate 14 (FIG. 2 - Refer to FIG. 4), the pedal 72 is connected to the -Y direction side end of the operated part main body 71 and is disposed on the -Y direction side of the container main body 10, and both sides of the operated part main body 71 in the X direction. It has a swing shaft portion 73 extending from the plane in the +X direction and the −X direction, respectively. The swing shaft portion 73 is rotatably inserted into a support hole (not shown) formed in a pair of side walls facing each other in the X direction to define the operated portion receiving groove 12 of the container body portion 10. ing. As a result, when the pedal 72 is depressed, the +Y direction end of the operated part main body 71 moves in the +Z direction centering on the axis (swing shaft part 73) that extends in the X direction. The operated portion main body 71 rotates so as to move.

The initial rotation stage and the final rotation stage immediately before the lid 30 comes into contact with the regulating part 25 in the opening operation of the lid 30 are set to coincide. Specifically, the distance in the X direction between the center of the shaft portion 32 and the center of the rotating portion 40 in the state shown in FIG. 8A is the same as the distance between the center of the shaft portion 32 and the center of the rotating portion 40 in the state shown in FIG. 8G. The rotation range of the lid portion 30 is set to match the distance in the X direction.

Specifically, the push-down surface 120 faces the push-up surface 110 on the +Z direction side of the push-up surface 110. Note that, as shown in FIG. 8A, in order to ensure the thickness of the second portion 82 (to improve the strength), the push-down surface 120 approaches the push-up surface 110 as it moves away from the shaft portion 32 in the +X direction. It is sloping. Note that the push-down surface 120 is not limited to being sloped as described above, but is arranged so as to allow the rotating section 40 to slide in the X direction in the process of rotating the lid section 30 to the closed position. It is sufficient if it extends along the direction.

As shown in FIG. 8A, the first side surface 130 has a first connection portion 131 connected at an obtuse angle to the push-up surface 110 in order to alleviate stress concentration at the connection portion with the push-up surface 110, and a push-down surface 120. A second connecting portion 132 is connected at an obtuse angle to the push-down surface 120 in order to alleviate stress concentration at the connecting portion, and a second connecting portion 132 extends in the Z direction so as to connect the first connecting portion 131 and the second connecting portion 132.

Next, with reference to FIGS. 8A to 8G, the operation of the rotating section 40 that rotates one of the pair of lid sections 30 will be described.

As shown in FIG. 8A, the lower end portion of the rotating portion 40 is in contact with the first push-up portion 111 when the lid portion 30 is in the closed position. From this state, by applying force to the pedal 72 of the operated part 70 and moving the pushing up surface 110 (first pushing up part 111) in the +Z direction, the rotating part 40 is moved in the X direction by moving the rotating part 40 in the X direction. The rotating part 40 is pushed up while sliding against the lid part 30, and the rotation of the lid part 30 toward the open position (initial rotation stage) can be started.

In addition, in this embodiment, as shown in FIGS. 8A and 8B, the first push-up portion 111 is moved so that the first push-up portion 111 terminates when the rotating portion 40 is located on the −Z direction side with respect to the shaft portion 32. Although the length of the push-up portion 111 is set, the length of the first push-up portion 111 is set so that the rotation portion 40 contacts the rotation portion 40 until the rotation portion 40 rotates to the same position in the Z direction as the shaft portion 32. It can also be extended. That is, the initial rotation stage may be set to a rotation range from a state in which the lid portion 30 is in the closed position to a state in which the rotation portion 40 has rotated to the same position as the shaft portion 32 in the Z direction. In this way, the component force in the tangential direction q of the rotating part 40 in the pushing up force by the pushing up surface 110 can be increased, so that the lid part 30 can be opened efficiently.

As shown in FIGS. 8C to 8D, the rotation of the lid part 30 further progresses and the rotation part 40 moves in the rotation range until the rotation part 40 moves to the same position in the Z direction as the shaft part 32. , and moves in the +X direction while sliding with the second push-up portion 112.

Further, as the rotation of the lid portion 30 progresses and the rotation portion 40 rotates in the +Z direction side relative to the shaft portion 32, the rotation portion 40 slides against the push-up surface 110, as shown in FIGS. 8E to 8G. While moving, move in the -X direction.

As described above, in this embodiment, the lid part 30 is rotated so that the distance in the X direction between the center of the shaft part 32 and the center of the rotating part 40 is the same in the initial rotation stage and the final rotation stage. A range has been set. Therefore, in this embodiment, the rotating portion 40 slides on the first push-up portion 111 in the initial rotation stage and the final rotation stage. As shown in FIG. 8A, in the initial rotation stage, the component force in the tangential direction q of the pushing up force by the pushing up surface 110 can be increased as described above, so that the lid part 30 can be efficiently rotated from the closed position. can be started. On the other hand, in the final rotation stage, the direction of inclination of the first push-up portion 111 does not function effectively in obtaining a component force for rotating the rotation portion 40 . Therefore, the force that contributes to the rotation of the lid part 30 immediately before it contacts the restriction part 25 can be suppressed to a small level, so that the burden on the lid part 30 and the container body 10 can be reduced.

As the lid portion 30 further rotates in the opening direction, as shown in FIG. Rotation in the direction is restricted.

When the force acting on the pedal 72 is released from the state shown in FIG. 8G, the push-down surface 120 moves in the -Z direction, thereby pushing down the rotating section 40 by the push-down surface 120, causing the lid section 30 to rotate to the closed position. can assist. As shown in FIGS. 8A to 8G, the push-down surface 120 according to the present embodiment becomes a push-up surface while being separated from the upper end of the rotating section 40 during the initial rotation stage to the final rotation stage of the lid section 30. It faces 110. Therefore, in this embodiment, the push-down surface 120 and the rotating part 40 slide between the initial rotation stage and the final rotation stage, and sliding resistance occurs between the push-down surface 120 and the rotation part 40. can be suppressed.

In the above embodiment, the cylindrical rotating part 40 has been described; however, the shape of the rotating part 40 is not limited to this, and the rotating part 40 extends in the Y direction over the rotating range of the lid part 30. It suffices if the outer peripheral surface has an arc surface such that the portion facing the push-up surface 110 when viewed from above is an arcuate surface.

For example, in the present embodiment, the rotating parts 40 provided on the +X direction side are not cylindrical so that there is a time difference in the closing timing of each of the pair of lid parts 30. Specifically, the rotating portion 40 has an arcuate surface provided at a portion facing the push-up surface 110 over the rotation range of the lid portion 30, and a circular arc surface provided at a portion facing the push-down surface 110 when the lid portion 30 is in the open position. and opposing flat surfaces. In this way, since the rotating part 40 has an outer circumferential surface such that the part facing the push-up surface 110 throughout the rotation range of the lid part 30 is an arcuate surface when viewed from the Y direction, The rotating portion 40 and the push-up surface 110 can be slid in the X direction. Further, since the rotating portion 40 has a flat surface, when the force on the pedal 72 is released, the cylindrical rotating portion 40 on the -X direction side that does not have a flat surface is pressed against the pressing surface 120. After the lid portion 30 on the −X direction side starts rotating in the closing direction upon contact, the rotating portion 40 on the +X direction side having a flat surface contacts the push-down surface 120 and closes the lid portion 30 on the +X direction side. Rotation in the closing direction is started. This causes a time difference in the timing at which each lid part 30 closes.

Although an example has been described in which the rotating portion 40 other than the rotating portion 40 having a cylindrical surface has a flat surface, the shape of the rotating portion 40 other than the arcuate portion is not particularly limited.

In addition, although the said embodiment demonstrated the example in which the shaft part 32 was provided in the lid part 30, the shaft part 32 may be provided in the container main body part 10.

Next, the features and effects of the lidded container 1 according to the present embodiment described above will be listed.

In this embodiment, a rotating portion 40 extending in the axial direction is provided at a position away from the rotating axis in the orthogonal direction over a rotating range between the closed position and the open position. Further, the rotating portion 40 has an outer circumferential surface such that a portion facing the pushing-up surface 110 is an arcuate surface over the rotating range of the lid portion 30. Therefore, in the process in which the push-up surface 110 pushes up the rotating section 40 (the process in which the rotating section 40 and the pushing-up surface 110 relatively slide in orthogonal directions), the downwardly facing region of the rotating section 40 is It is a circular arc regardless of the rotation position of the rotating portion 40 in the orthogonal direction about the rotation axis. Therefore, in this embodiment, the shape of the push-up surface 110 can be simply formed so as to come into contact at an angle as close to perpendicular as possible to the rotating portion 40 that relatively moves in the orthogonal direction. Specifically, in this embodiment, the push-up surface 110 is formed in a shape along the orthogonal direction. As a result, it is possible to suppress the sliding resistance between the rotating part 40 and the pushing-up surface 110 from increasing, so that the pushing-up surface 110 rapidly moves upward when the operated part 70 is stepped on forcefully. Even in this case, the pair of lid parts 30 can be opened smoothly.

Furthermore, in the present embodiment, the force for rotating the lid 30 to the open position is applied more quickly than when the lower end of the rotating unit 40 is away from the push-up surface 110 when the lid 30 is in the closed position. can be transmitted from the push-up surface 110 to the lower end of the rotating part 40. Therefore, according to this embodiment, the lid portion 30 can be opened quickly.

Moreover, in this embodiment, since the rotating part 40 is located below the rotating shaft, the rotating part 40 and the coupling mechanism 100 for pushing it up are housed under the lid part 30, and the lidded container 1 becomes bulky. You can keep it from getting too high. However, when pushing up the rotating part 40 located below the rotating shaft on a horizontal surface, it is difficult to obtain a sufficient force in the direction of rotating the rotating part 40 about the rotating shaft. Therefore, in the above configuration, the push-up surface 110 has a first push-up portion 111 that is inclined in a direction more advantageous than the horizontal plane with regard to obtaining a force for rotating the lid part 30 to the open position in the initial rotation stage. There is. Therefore, compared to the case where the rotating part 40 is pushed up by the first pushing up part 111 extending parallel to the orthogonal direction, the force required to rotate the lid part 30 to the open position in the initial rotation stage is reduced. can do. In addition, since the push-up surface 110 has a second push-up portion 112 extending perpendicularly from the first push-up portion 111, the upward force for pushing up the rotating portion 40 is efficiently transmitted in the subsequent rotation stage. be able to.

Furthermore, in this embodiment, by releasing the force acting on the operated portion 70 and moving the push-down surface 120 downward, the rotating portion 40 can be pushed down in the direction in which the lid portion 30 rotates to the closed position. can. Therefore, by releasing the force acting on the operated portion 70, it is possible to assist the rotation of the lid portion 30 to the closed position.

Moreover, in this embodiment, the push-down surface 120 extends along the orthogonal direction. Thereby, it is possible to suppress the sliding resistance between the rotating part 40 and the push-down surface 120 from increasing, so that the pair of lid parts 30 can be closed smoothly.

Furthermore, in the present embodiment, since the rotation of the lid part 30 beyond the closable area is restricted by the restriction part 25, the force acting on the operated part 70 is released and the pressing surface 120 is moved downward. By doing so, the lid portion 30 can be rotated to the closed position.

Moreover, in this embodiment, the distance in the orthogonal direction between the center of the rotation axis and the center of the rotation part 40 is the same in the initial rotation stage and the final rotation stage. Furthermore, in the initial rotation stage, the rotating portion 40 is located below the rotation axis. Therefore, in this final rotation stage, the first push-up portion 111 does not function effectively in obtaining the component force in the tangential direction q of the rotation portion 40 . In other words, in the final rotation stage, the force for rotating the lid part 30 can be kept small, so the load on the lid part 30 and the regulating part 25 when the lid part 30 comes into contact with the regulating part 25 can be kept small. I can do it.

Moreover, in this embodiment, since the push-up surface 110 and the push-down surface 120 are connected to each other by two side parts, the relative positions of the push-up surface 110 and the push-down surface 120 can be reliably maintained. On the other hand, if the push-up surface 110 and push-down surface 120 are vertically connected to both side surfaces, there is a risk that stress will be concentrated at the connection between the push-up surface 110 and push-down surface 120 and both side surfaces during push-up and push-down. There is. On the other hand, in this embodiment, the push-up surface 110 and the push-down surface 120 and both side surfaces are connected at an obtuse angle by the first connection portion 131, the second connection portion 132, the third connection portion 141, and the fourth connection portion 142. Therefore, stress concentration can be alleviated.
