Description

The disclosed technology relates to a display device used to display information to passersby and others.

An example of a conventional display device of this type is the sign described in Patent Document 1. The sign device in this document is made by connecting the upper edges of two display plates. In this sign device, a portion called a split handle is provided on the upper edge of each display plate. When connected, the split handles are integrated to form a handle. To connect the two components, a protrusion is formed on one of the mating surfaces of the split handles and a hole is formed on the other.

JP 2004-257018 A

The above-mentioned conventional technology has the following problems. First, there is a manufacturing problem. When making the marker of Patent Document 1 using ordinary resin molding, protrusions are formed on both of the above-mentioned mating surfaces. After that, one of the protrusions is cut away to form a hole. As such, the marker cannot be completed through the molding process alone, and post-processing in the form of cutting is required.

There are also problems with use. The connection work is not necessarily easy. To connect the plates, the protrusions must be inserted into the holes mentioned above. To do this, the display plates must be tilted relative to each other so that the mating surfaces face each other diagonally. This is because, in addition to the split handles mentioned above, there are other shaped parts such as shaft tubes on the top edge of the display plates, which makes it difficult to face the mating surfaces parallel to each other. For this reason, the connection work requires skill and is not necessarily easy.

The disclosed technology has been made to solve the problems of the conventional technology described above. In other words, the objective is to provide a display device that is easy to manufacture and easy to connect.

In one aspect of the disclosed technology, the display device has a first display member and a second display member, and each of the first display member and the second display member is provided with a connecting portion that connects one side of the first display member and the second display member while allowing an angle change around an axis parallel to the one side by assembling them together, and the first display member and the second display member are integrated in a connected state in which they are connected by the connecting portion to form a handle portion, and the display device has a first divided handle portion formed on the first display member and a second divided handle portion formed on the second display member, and a portion including the axial tips of the first divided handle portion and the second divided handle portion has an internal structure in the connected state. The face side is cut out, and a fitting portion is formed that fits together in a connected state and allows a closed state in which the opposite side of the one side of the first display member and the opposite side of the one side of the second display member are close to or in contact with each other, and an open state in which the opposite sides are separated from each other. The fitting portions of the first and second divided handle portions each have a first section with a small cutout angle and a second section with a large cutout angle, and in the connected state, the first section of the first divided handle portion fits together with the second section of the second divided handle portion, and the second section of the first divided handle portion fits together with the first section of the second divided handle portion.

In the display device of the above embodiment, one side of the first display member and one side of the second display member are connected to each other by a connecting portion so that the angle can be changed. In this connected state, the first divided handle portion of the first display member and the second divided handle portion of the second display member are integrated to form the handle portion. At the fitting portion at the tip of the first divided handle portion and the second divided handle portion, the first section of the first divided handle portion and the second section of the second divided handle portion are fitted together, and the second section of the first divided handle portion and the first section of the second divided handle portion are fitted together. At this fitting portion, a closed state in which the opposite sides of the first and second display members are close to or in contact with each other, and an open state in which the opposite sides are separated from each other are possible. This shape can be formed by molding only, without post-processing such as cutting. In addition, the connection operation can be easily performed by simply aligning the two display members in parallel and moving them parallel to each other.

In the display device of the above aspect, the fitting portions of the first and second divided handle portions are arranged in the order of the first section and the second section from the axial tip, the first handle surface is formed in each of the sections of the first and second divided handle portions other than the fitting portions, and the second handle surface is formed in each of the first and second divided handle portions, and it is preferable that both the first and second handle surfaces are formed so as to include an angular position that is downward when the one side is in an upward position relative to the axis in either the closed or open state. In this way, the lower side of the handle portion is occupied by the first or second handle surface in either the closed or open state. This is gentle on the user's hands.

In any of the above-mentioned aspects of the indicator, it is further preferable that each fitting portion is formed with a closed state abutment surface that abuts in the closed state and an open state abutment surface that abuts in the open state, and that both ends of the angle change range of the first indicator member and the second indicator member are defined by the abutment of the closed state abutment surfaces and the abutment of the open state abutment surfaces. In this way, both the closed state and the open state are defined as stable positions by the abutment of the abutment surfaces.

In an indicator having an abutment surface, in each first section, the closed state abutment surface and the open state abutment surface are formed to form a concave cross angle when viewed on a cross section perpendicular to the axis, and in each second section, the closed state abutment surface and the open state abutment surface are formed to form a convex cross angle when viewed on a cross section perpendicular to the axis, and it is desirable that the concave cross angle be larger than the convex cross angle. In this way, the closed state and the open state are defined as the two ends of the range in which both indicator members can rotate about the axis.

In any embodiment of the display device in which abutment surfaces are formed, it is further preferable that both the closed state abutment surface and the open state abutment surface are formed only within a range that is smaller than the radius of the first and second divided handle portions with respect to the axis. In this way, in both the closed and open states, the abutment surfaces come into contact with each other only in places that are difficult for the user's fingertips to reach, providing a high level of safety.

In an indicator in which the concave intersection angle is greater than the convex intersection angle and each abutment surface is formed only within the range of small diameter, it is further desirable that in each fitting portion, at a portion outside the maximum radius where the closed state abutment surface and the open state abutment surface are formed with respect to the axis, a recessed portion is formed that is recessed from the closed state abutment surface or the open state abutment surface when viewed on a cross section perpendicular to the axis. In this way, there is a space created by both recesses outside the portion where the abutment surfaces abut against each other, which increases safety.

In any of the above-mentioned display devices, it is further preferable that each fitting portion is provided with a movement restriction surface that restricts the axial movement of the first and second display members. In this way, in the connected state, the relative axial movement of both display members is restricted by the movement restriction surface, and the posture is stabilized.

This configuration provides a display device that is easy to manufacture and easy to connect.

The following describes in detail an embodiment that embodies the disclosed technology, with reference to the attached drawings. The display device 1 according to this embodiment shown in FIG. 1 is formed by connecting two display plates 2. The display plates 2 are rectangular members, and in the display device 1, the upper sides of the display plates 2 are connected to each other. The display plates 2 that constitute the display device 1 have a connecting portion 3 and a divided handle portion 4 on the upper side, as shown in FIG. 2. The connecting portion 3 is a portion for connecting the upper sides of the display plates 2 to each other with an insert pin 5. The divided handle portions 4 are a portion that is integrated in a connected state to form the handle portion 6, as shown in FIG. 1.

As shown in Figure 2, a frame-shaped portion 9 is formed around the periphery of the front side of the display board 2. A suitable display panel can be fixed to the front side of the display board 2 using this frame-shaped portion 9 and a removable fastener 7. This allows the display board 2 to function as a display member that shows passersby and others the contents written on the display panel. Figure 2 also shows an anti-slip member 8 that is attached to the bottom edge of the display board 2.

In the display device 1, the crossing angle between the display plates 2 can be changed within a certain range, with the connecting part 3 and the handle part 6 as the axis. The state shown in Figure 1 is an open state in which the bottom sides of the display plates 2 are separated from each other. In the open state, the display device 1 can be placed stably upright on the floor or the ground. In this state, the display content of the display panel fixed to the display plate 2 can be easily seen by passersby, etc.

In addition to the open state described above, the display device 1 can also be in a closed state as shown in FIG. 3. In the closed state, the lower sides of the display boards 2, i.e., the parts where the non-slip members 8 are attached, are close to or in contact with each other. In the closed state, the display device 1 is very compact, with a thickness equivalent to only two display boards 2. Although the closed display device 1 cannot be stably placed upright on the floor or the ground, it is convenient for storage because it saves space. For example, as shown in FIG. 4, the display devices 1 in the closed state can be stored flat in a stacked state. In the stacked state shown in FIG. 4, the top and bottom orientations of the display devices 1 are opposite to those of adjacent display devices. This stacking method allows the display device 1 to remain almost horizontal even if there are many layers. The display device 1 can be closed and stacked even if the display panel is fixed to the display board 2.

The open state (Fig. 1) and closed state (Fig. 3) can be switched between by simply rotating the display panels 2, without releasing the connection by the connecting part 3. There is no problem even if the display panel is fixed to the display panel 2. The axis of rotation is parallel to the upper side of the display panel 2 and is defined by the connecting part 3 and the handle part 6.

The display plate 2 in a separate state before being connected will be described with reference to Figs. 5 and 6. Fig. 5 shows the front side, i.e., the surface that is the outside of the display device 1 in the connected state, and Fig. 6 shows the back side, i.e., the surface that is the inside of the display device 1 in the connected state. Figs. 5 and 6 show a state in which the insert pin 5, fastener 7, and anti-slip member 8 are not attached. In the display device 1 of this embodiment shown in Figs. 1 to 3, the two display plates 2 are the same. In the following description, in order to distinguish between the two display plates 2 in the display device 1, one display plate 2 may be referred to as the first display plate 21 and the other display plate 2 as the second display plate 22. When there is no need to distinguish between the two, they will simply be referred to as display plates 2.

Connecting parts 3 are provided on both ends of the upper side of the display panel 2. As can be seen from the back view of FIG. 6, the connecting part 3 is a half-pipe shaped part with a concave back side. A ring 31 is formed near the left end of the connecting part 3 on the left side as viewed in FIG. 6. A ring 32 is formed inside the ring 31. Between the rings 31 and 32, there is a blank section 33 with no ring. There is also a blank section 34 inside the ring 32. A ring 35 is formed on the connecting part 3 on the right side as viewed in FIG. 6, slightly inward from the right end. The area outside the ring 35 is a blank section 36. A ring 37 is formed inside the ring 35. There is also a blank section 38 between the rings 35 and 37.

When two identical display boards 2 are assembled with their back faces facing each other and their top edges touching, the connecting part 3 on the left side of the first display board 21 and the connecting part 3 on the right side of the second display board 22 are combined. At that time, the ring 35 of the second display board 22 enters the blank section 33 of the first display board 21, and the ring 37 of the second display board 22 enters the blank section 34 of the first display board 21. Looking at this situation in reverse, the ring 31 of the first display board 21 enters the blank section 36 of the second display board 22, and the ring 32 of the first display board 21 enters the blank section 38 of the second display board 22. The same situation occurs on the other side of the top edge of the display board 2.

In this state, the insert pin 5 is inserted from the outside into the part where the connecting parts 3 of both display plates 2 face each other and form a roughly pipe shape. Once inserted, the insert pin 5 penetrates the four rings 31, 32, 35, and 37. With the insert pin 5 inserted, the two display plates 2 cannot be separated. This is the state in which the two display plates 2 are connected to form the display device 1. In this connected state, the two display plates 2 can rotate relative to each other with the insert pin 5 as the axis of rotation. This rotation action switches between the aforementioned open state (Figure 1) and closed state (Figure 3). In order to prevent the connecting parts 3 from interfering with each other in the open state, a gap is provided between the tops 39 of the connecting parts 3 in the closed state (Figure 3).

By connecting the connecting parts 3 as described above, the split handle parts 4 are also united to form the handle part 6. In the connected state, the entire display device 1 consisting of two display plates 2 can be lifted by grasping and lifting the handle part 6 with the hand. In addition to this function, the split handle part 4 also has the function of defining both ends of the angle range of the aforementioned rotational movement of both display plates 2. This angle range defining function ensures that the display device 1 is in a stable position in both the open and closed states. This function of the split handle part 4 is explained using Figures 7 to 18.

As shown in Figures 7 and 8, the base 41 of the divided handle portion 4 that is connected to the main body of the display panel 2 is a columnar portion with a circular cross section. The axis of rotation of the aforementioned insertion pin 5 passes geometrically through the inside of this base 41. The portion of the base 41 that is relatively close to the connecting portion 3 is connected to the main body.

A fitting portion 42 is formed on the side of the split handle portion 4 farther from the base portion 41 as viewed from the connecting portion 3. The fitting portion 42 is a portion having a cross-sectional shape that is partially cut out from the circular cross-section of the base portion 41. The fitting portion 42 is formed connected to the base portion 41. The outer shape of the fitting portion 42 other than the cut-out portion is an arc surface that is continuous with the circular surface of the cross-section of the base portion 41. The fitting portion 42 is further divided into two sections: a first section 43 on the tip side in the axial direction, and a second section 44 on the base portion 41 side. The second section 44 is cut out to a greater extent than the first section 43. In both the first section 43 and the second section 44, the back side is cut out, not the front side.

When the above-mentioned connection is made by the connecting portion 3, the first section 43 of the first display panel 21 fits into the second section 44 of the second display panel 22, and the second section 44 of the first display panel 21 fits into the first section 43 of the second display panel 22. As a result, in the connected state, the divided handle portions 4 of both display panels 2 are integrated together, including the fitting portion 42, to form the above-mentioned handle portion 6.

The shapes of the first section 43 and the second section 44 will be explained in more detail. Figures 9 and 10 show cross sections perpendicular to the axial direction of the first section 43 and the second section 44. In both Figures 9 and 10, the left side of the figure corresponds to the front side of the display panel 2, and the right side of the figure corresponds to the back side. Also, the view is from the location of the first section 43 and the second section 44 toward the base 41.

9, the cross-sectional shape of the first section 43 is composed of an arc-shaped portion 45 and a recessed portion 46. The arc-shaped portion 45 is a surface that is continuous with the circular surface 47 of the outer shape of the base 41. The recessed portion 46 is a surface that is recessed from the circular surface 47 of the outer shape of the base 41. For the sake of explanation, the shape of the recessed portion 46 and the recessed portion 53 described later may be expressed as a "notched shape". However, the recessed portions 46 and 53 do not need to be actually notched, and may be molded into that shape from the beginning. In the first section 43 in FIG. 9, the arc-shaped portion 45 occupies nearly half of the entire outer shape of the base 41. The recessed portion 46 is located toward the back side in terms of the front and back of the display board 2, or more specifically, slightly upward on the back side.

The recess 46 further includes a first contact surface 48, a second contact surface 49, a first recess 50, and a second recess 51. The first contact surface 48 and the second contact surface 49 are formed within a radius smaller than the radius of the circular surface 47 of the outer shape of the base 41. The first contact surface 48 and the second contact surface 49 together form a concave shape. The first recess 50 and the second recess 51 are formed in a portion outside the maximum radius where the first contact surface 48 and the second contact surface 49 are formed. The first recess 50 is recessed from the first contact surface 48 as viewed in FIG. 9. The second recess 51 is recessed from the second contact surface 49.

As shown in FIG. 10, the cross-sectional outer shape of the second section 44 is composed of an arc-shaped portion 52 and a recessed portion 53. The arc-shaped portion 52 is a surface that is continuous with the circular surface 47 of the base 41 and the arc-shaped portion 45 of the first section 43. The recessed portion 53 is a surface that is recessed from the circular surface 47 of the outer shape of the base 41. In the second section 44 of FIG. 10, the arc-shaped portion 52 occupies only a small portion of the entire outer shape of the base 41. Therefore, the cutout angle of the recessed portion 53 of the second section 44 (β in FIG. 10) is considerably larger than the cutout angle of the recessed portion 46 of the first section 43 (α in FIG. 9). The arc-shaped portion 52 is located facing the front side in terms of the front and back of the display board 2. In other words, in the second section 44, the recessed portion 53 faces the back side of the front and back.

The recess 53 further includes a first contact surface 54, a second contact surface 55, a first recess 56, and a second recess 57. The first contact surface 54 and the second contact surface 55 are formed within a range of a radius smaller than the radius of the circular surface 47 of the base 41. The first contact surface 54 and the second contact surface 55 are convex together. The first recess 56 and the second recess 57 are formed at a portion outside the maximum radius at which the first contact surface 54 and the second contact surface 55 are formed. The first recess 56 is recessed from the first contact surface 54 as viewed in FIG. 10. The second recess 57 is recessed from the second contact surface 55.

The second abutment surface 55 is a surface continuing with the second abutment surface 49 of the first section 43. The second recessed portion 57 is a recessed surface continuing with the second recessed portion 51 of the first section 43. In contrast, the first abutment surface 54 and the first recessed portion 56 are surfaces and recessed surfaces different from the first abutment surface 48 and the first recessed portion 50 of the first section 43. The intersection angle φ between the first abutment surface 54 and the second abutment surface 55, which are convex in the second section 44, is smaller than the intersection angle θ between the first abutment surface 48 and the second abutment surface 49, which are concave in the first section 43. More specifically, the intersection angle θ is an obtuse angle, while the intersection angle φ is an acute angle.

Returning to FIG. 7, a first end face 58 is formed at the tip of the first section 43 of the fitting portion 42. A second end face 59 is formed at the boundary between the base 41 and the fitting portion 42. As shown in FIG. 8, a third end face 60 is formed at the boundary between the first section 43 and the second section 44. The first end face 58 to the third end face 60 are all surfaces perpendicular to the axial direction. The second end face 59 also appears in FIG. 9 and FIG. 10.

The relationship between the split handle portion 4 having the fitting portion 42 configured as described above and the connecting operation by the connecting portion 3 will now be described. Figure 11 shows the state near the split handle portions 4 when the back faces of the two display boards 2 to be connected are facing each other and brought close together. In the state of Figure 11, the fitting portions 42 of the split handle portions 4 in particular face each other. More specifically, the first section 43 of the first display board 21 faces the second section 44 of the second display board 22, and the first section 43 of the second display board 22 faces the second section 44 of the first display board 21.

A cross-sectional view of the facing situation is shown in Figure 12. Shown in Figure 12 is the facing location of the second section 44 of the first display board 21 and the first section 43 of the second display board 22. In Figure 12, the second section 44 of the first display board 21 and the first section 43 of the second display board 22 are in a situation where the recessed portion 53 and the recessed portion 46 face each other. The facing location of the first section 43 of the first display board 21 and the second section 44 of the second display board 22 is in a similar situation, although the left and right are reversed from Figure 12.

As a result, when the two display plates 2 are brought closer together from the state shown in Figs. 11 and 12, the engaging portions 42 engage with each other without the arc-shaped portions 45 and 52 colliding with each other, resulting in the state shown in Figs. 13 and 14. This is what is meant by the name "engagement portion." This is the connection operation, which passes through the state shown in Fig. 15 along the way. Once the state shown in Figs. 13 and 14 is reached, the aforementioned insertion pin 5 is inserted to complete the connection. The state shown in Figs. 13 and 14 is the closed state shown in Fig. 3. From this state, the display plates 2 can be rotated to open and close as described above. A partial cross-sectional view of the open state is shown in Fig. 16.

The state of the fitting portion 42 in the closed and open states will be further explained. FIG. 17 shows an enlarged view of the fitting portion 42 in the cross section of the closed state in FIG. 14. As shown in FIG. 17, in the closed state, the first abutment surface 54 (second section 44) of the first display panel 21 and the first abutment surface 48 (first section 43) of the second display panel 22 abut against each other. This prevents the second display panel 22 from rotating further clockwise and the first display panel 21 from rotating further counterclockwise in FIGS. 14 and 17. The same state is observed at the fitting point between the first section 43 of the first display panel 21 and the second section 44 of the second display panel 22, although the orientations are reversed.

As a result, the closed state is a stable position for the display device 1, and the lower ends of the two display plates 2 are prevented from colliding violently against each other. In other words, the first abutment surface 54 and the first abutment surface 48 are closed state abutment surfaces that abut against each other in the closed state. This abutment defines one end of the closed side of the angle change range of both display plates 2.

Switching the display device 1 from the closed state to the open state means rotating the second display panel 22 counterclockwise and the first display panel 21 clockwise in Figs. 14 and 17. This operation is possible because the cross angle θ in Fig. 9 is greater than the cross angle φ in Fig. 10. Fig. 18 shows an enlarged view of the fitting portion 42 in the open state cross section of Fig. 16, which shows the state after this operation. As shown in Fig. 18, in the open state, the second abutment surface 55 (second section 44) of the first display panel 21 and the second abutment surface 49 (first section 43) of the second display panel 22 are in abutment. This prevents the second display panel 22 from rotating further counterclockwise and the first display panel 21 from rotating further clockwise in Figs. 16 and 18. The same situation occurs at the fitting portion between the first section 43 of the first display panel 21 and the second section 44 of the second display panel 22, although the left and right directions are reversed.

This provides a stable posture for the display device 1 in the open state, and prevents the tops 39 of the connecting parts 3 of the two display plates 2 from colliding violently against each other. In other words, the second abutment surface 55 and the second abutment surface 49 are open state abutment surfaces that abut against each other in the open state. This abutment defines one end of the open side of the angle change range of both display plates 2. As mentioned in FIG. 3 that there is a gap between the tops 39 in the closed state, but as shown in FIG. 16, even in the open state, the tops 39 do not collide with each other and there is a small gap therebetween. This provides a high level of safety even if the user's fingertips are near the connecting parts 3 when opening the display device 1.

The engagement portion 42 also improves safety during opening and closing operations. As shown in FIG. 17, the first contact surface 54 and the first contact surface 48 are in contact with each other, but there is a gap on the outside of the contact surface caused by the first recessed portion 50 (first section 43) and the first recessed portion 56 (second section 44). As shown in FIG. 18, the second contact surface 55 and the second contact surface 49 are in contact with each other, but there is a gap on the outside of the contact surface caused by the second recessed portion 51 (first section 43) and the second recessed portion 57 (second section 44). As a result, the contact between the contact surfaces occurs only at a position far from the user's fingertips, and a space is left outside the contact position where the user's fingertips can fit. This provides high safety.

In the handle portion 6 after connection shown in Figure 13, the second end face 59 of the first display panel 21 (see Figure 7) and the first end face 58 of the second display panel 22 (see Figure 7) are in close proximity to or in contact at the location of arrow A. The second end face 59 of the second display panel 22 and the first end face 58 of the first display panel 21 are in close proximity to or in contact at the location of arrow B. The third end faces 60 (see Figure 8) of both display panels 2 are in close proximity to or in contact at the location of arrow C. The proximity or contact of these end faces restricts the movement of both display panels 2 relative to each other in the axial direction. In other words, each of these end faces is a movement restricting surface.

As shown in Figures 17 and 18, the arc-shaped portion 45 of the outer shape of the first section 43 includes the position of arrow D, i.e., the position directly below, in both the closed and open states. This is because in the first section 43, as described in Figure 9, the cutout angle α of the recessed portion 46 is not very large, and the angle range occupied by the arc-shaped portion 45 is accordingly wide. As a result, in both the closed and open states, when the user holds the handle portion 6 and lifts the display device 1, the arc-shaped portion 45 mainly comes into contact with the user's hand in the fitting portion 42 section. This provides a natural feel to the user.

Even in the base 41 section of the handle 6, the position directly below indicated by arrow D is occupied by the circular surface 47 as shown in Figure 10. This also provides a natural feel to the user. The arc-shaped portion 52 of the second section 44 is not as important as the arc-shaped portion 45 because it does not face downward in either the closed or open state, but it does have the effect of making the feel natural because it may come into contact with the hand of the user holding the handle 6. The circular surface 47 is the first handholding surface, and the arc-shaped portion 45 is the second handholding surface. The arc-shaped portion 52 is the third handholding surface.

As described above in detail, according to this embodiment, a fitting section 42 having a first section 43 and a second section 44 is formed at the joining point of the tip of each divided handle section 4 of the two display plates 2 that are connected to form the display device 1. This fitting section 42 is provided with various abutment surfaces that determine the open and closed states. With this configuration, there is no need to insert a protrusion of one display plate into a hole in the other display plate. Therefore, the required shape can be formed only by molding, and post-processing such as cutting is not required. When connecting, the operation is simple, as it is only necessary to face both display plates 2 in parallel and move them in parallel. In this way, a display device 1 that is easy to manufacture and easy to connect is realized.

Note that this embodiment is merely an example and does not limit the disclosed technology in any way. Therefore, the disclosed technology can be improved and modified in various ways without departing from the scope of the invention. For example, the connecting portion 3 may be configured so that the connection is completed without the insertion pin 5. The two display panels 2 do not have to be the same. In addition, they are not limited to the vertically elongated rectangle shown in the figure. They may be horizontally elongated rectangles, or they do not have to be rectangular. The cross-sectional shape of the base 41 does not have to be circular as a whole. It is sufficient that at least the lower surface side is arc-shaped. The divided handle portion 4 of each display panel 2 is not limited to a configuration in which it extends from the main body of the display panel 2, but may be a configuration in which it extends from the connecting portion 3.

The display board 2 may be of a type that does not use a display panel. It may be one in which the displayed content is unchanging, or one in which the user can freely write and erase letters and pictures using an appropriate writing implement, like a whiteboard. It may also be a component that uses light-emitting or color-emitting elements and allows the displayed content to be electrically operated.

In the above embodiment, the second abutment surface 55 (FIG. 10) of the second section 44 and the second abutment surface 49 (FIG. 9) of the first section 43 are continuous in the fitting portion 42, while there is a step between the first abutment surface 54 (second section 44) and the first abutment surface 48 (first section 43). However, this is not limited to the above, and the first abutment surface may be continuous in both sections and the second abutment surface may have a step between the two sections. Both the first abutment surface and the second abutment surface may have a step between the two sections. The same can be said about the relationship between the second recessed portion 57 and the second recessed portion 51 and the relationship between the first recessed portion 56 and the first recessed portion 50. In either case, it is sufficient that the intersection angle θ (recessed angle) in FIG. 9 is larger than the intersection angle φ (protruding angle) in FIG. 10.
