JP 2004-245421 A Design Registration No. 1328829

It is desirable to facilitate compactness of the hanging device when not being used to hang a suspended object.

A hanging device according to one aspect of the present disclosure includes a hook in which a hook base and a hook tip are arranged at a distance from each other to define a hook opening, and a hook extension portion extends so that a hook recess is formed between the hook base and the hook tip, a main body to which a suspended object is to be attached, and an attachment member having a connecting portion connected to the main body for engagement with the hook base. A rotating portion is provided on one of the hook base and the connecting portion, and a receiving portion that receives the rotating portion is provided on the other of the hook base and the connecting portion, and the receiving portion receives and holds the rotating portion, thereby engaging the attachment member and the hook so that they can rotate relatively. The hook base and the connecting portion are configured so that when either the hook or the attachment member is rotated relative to the other such that the attachment member rotates to a position adjacent to the hook tip while the hook and the attachment member are arranged on the same plane, (i) the attachment member can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening, or (ii) the attachment member can cross an imaginary line set at a position corresponding to the minimum opening width of the hook opening.

In some embodiments, a first virtual line extending from the hook base toward the bottom of the hook recess is represented by a combination of a first vector extending in the depth direction of the hook recess and a second vector extending from the tip of the first vector to the bottom of the hook recess perpendicular to the first vector, and a second virtual line and a third virtual line parallel to the first vector are set to sandwich the hook base and the hook tip, and assuming that the second virtual line is set with respect to the hook base and the third virtual line is set with respect to the hook tip, the attachment member does not cross the third virtual line during the entire process of either the hook or the attachment member being rotated relative to the other so that the attachment member rotates to a position adjacent to the hook tip while the hook and the attachment member are arranged on the same plane.

The receiving portion may have a groove for movement of the shaft portion, the tip of which is fixed to the rotating portion. The body portion of the mounting member may include a rod portion, a first arc-shaped portion extending in an arc from the first end of the rod portion toward the connecting portion, and a second arc-shaped portion extending in an arc from the second end of the rod portion toward the connecting portion.

In some embodiments, the length of the groove is set so that when either the hook or the attachment member is rotated relative to the other such that the attachment member is rotated to a position adjacent to the tip of the hook while the hook and the attachment member are disposed on the same plane, (a) the attachment member can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening or an imaginary line set at a position corresponding to the minimum opening width of the hook opening, and/or (b) one of the first and second arc-shaped portions can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening, or the bar portion can be oriented parallel to the second and third imaginary lines.

In some embodiments, the hook base and the connecting portion are configured such that (a) one of the first and second arc-shaped portions can cross an imaginary line set at a position corresponding to the maximum opening width of the hook opening, or (b) the bar portion can be oriented parallel to the second and third imaginary lines when either the hook or the mounting member is rotated relative to the other such that the mounting member is rotated to a position adjacent to the hook tip while the hook and the mounting member are disposed on the same plane.

The hook may have a side that extends flat along the second imaginary line. The second imaginary line and the third imaginary line may be tangents to an imaginary perfect circle or ellipse that defines the curvature of the outer surface of the hook. The hook may be rotatable relative to the attachment member such that the second imaginary line and the third imaginary line are oriented parallel to the side edges of the suspended object when the main body of the attachment member is attached to the suspended object.

In some embodiments, assuming that a virtual perfect circle or ellipse is set to define the curved shape of the hook, the hook base and the connecting portion are configured so that when either the hook or the mounting member is rotated relative to the other such that the mounting member rotates to a position adjacent to the hook tip while the hook and the mounting member are disposed on the same plane, the mounting member can intersect with the virtual perfect circle or ellipse.

The hook base may be provided with a receiving portion, and the connecting portion may be provided with a pivot portion. The hook may be J-shaped, and the body portion may be D-shaped. The hook base and connecting portion may be configured such that the attachment member is positioned adjacent to the hook tip so as to be detachable therefrom.

The groove may have a narrow portion where the groove width is reduced so that the attachment member can be releasably positioned at a position adjacent to the tip of the hook. At least one protrusion can be provided on the outer peripheral surface of the shaft portion that can come into contact with a protrusion provided on the receiving portion to form the narrow portion. The protrusion on the outer peripheral surface of the shaft portion can come into contact with the protrusion provided on the receiving portion to form the narrow portion, thereby notifying the user that the attachment member has reached a position adjacent to the tip of the hook.

The receiving portion includes first and second opposing portions arranged opposite each other, and the space between the first and second opposing portions can form a groove for movement of the shaft portion, the tip of which is fixed to the rotating portion. One end of the groove on the hook tip side can be shaped to narrow stepwise or continuously.

One aspect of the present disclosure can facilitate miniaturization of the hanging device when it is not being used to hang an object to be hung.

Various embodiments and features will be described below with reference to the drawings. Those skilled in the art will be able to combine the various embodiments and/or features without the need for excessive explanation, and will also be able to understand the synergistic effects of such combinations. In principle, overlapping explanations between embodiments will be omitted. The reference drawings are primarily intended to describe the invention, and have been simplified for the convenience of drawing. Each feature is not only effective for the hanging device disclosed in this application, but is understood to be a universal feature that is also applicable to various other hanging devices not disclosed in this specification.

A non-limiting hanging device 1 according to the present disclosure is shown in FIG. 1. Hanging device 1 is a combination of hook 2 and mounting member 3 manufactured by injection molding of resin. Note that hook 2 and mounting member 3 can be molded simultaneously using a common injection molding device and a common mold device, and the assembly process of hook 2 and mounting member 3 is not essential. Of course, the two can also be injection molded separately and combined to manufacture the hanging device. For convenience, the description may be given with reference to the up-down direction, left-right direction, and front-back direction shown in FIG. 1. The front-back direction may be alternatively referred to as the thickness direction, and the up-down direction may be alternatively referred to as the vertical direction.

1 to 3, in the hook 2, the hook base 21 and the hook tip 22 are arranged at a distance from each other to define the hook opening 25, and the hook extension 24 extends so that the hook recess 23 is formed between the hook base 21 and the hook tip 22. In the state shown in FIG. 1 (see also FIG. 8), the hook extension 24 extends in a certain direction (upper right direction in FIG. 1) to move away from the hook base 21, and then extends with a predetermined curvature (the curvature of a virtual perfect circle C1 (see FIG. 8) that defines the curved form of the outer surface 2b of the hook 2) (extending from upper right to upper left, to the left, and to lower left in FIG. 1) to reach the hook tip 22. This gives the hook 2 an approximately J-shaped shape. The inner surface 2a and the outer surface 2b of the hook 2 also extend in a J-shape. The hook opening 25 is always open, but a closing member may be added to the hook 2 to close the hook opening 25.

The mounting member 3 has a main body 31 to which the suspended object 9 is to be attached, and a connecting portion 32 connected to the main body 31 for engagement with the hook base 21. The main body 31 is a D-shaped ring (i.e., a D-ring), and has a rod 5, a first arc-shaped portion 61 extending in an arc from the first end 51 of the rod 5 toward the connecting portion 32, and a second arc-shaped portion 62 extending in an arc from the second end 52 of the rod 5 toward the connecting portion 32, which define a flat closed space 38. The rod 5 extends in the left-right direction with a substantially constant cross-sectional shape (for example, a circular cross-section). The first arc-shaped portion 61 and the second arc-shaped portion 62 become thicker (front-to-back width in FIG. 1) as they extend upward from the rod 5, thereby strengthening the connection with the shaft portion 43 described below. The connecting portion 32 is a pillar portion protruding from the main body portion 31 (specifically, a pillar portion connecting the pivot portion 41 and the shaft portion 43 described below), but is not necessarily limited to this. The connecting portion 32 extends upward from the connection point between the first arc-shaped portion 61 and the second arc-shaped portion 62.

To engage the hook 2 with the mounting member 3, a rotating part 41 can be provided on one of the hook base 21 and the connecting part 32, and a receiving part 42 that receives the rotating part 41 can be provided on the other of the hook base 21 and the connecting part 32. The receiving part 42 receives and holds the rotating part 41 (e.g., loosely fitted), so that the mounting member 3 and the hook 2 are engaged so as to be capable of rotating relative to one another.

The rotating part 41 is appropriately shaped for its smooth rotation, for example (i) shaped to have a smoothly curved surface on at least a part of its outer surface, or (ii) shaped as a polyhedron having three or more faces. The edges between adjacent faces of the polyhedron may be chamfered. In some cases, the rotating part 41 is formed with two separate parting lines corresponding to the boundary of the mold device (e.g., the boundary between the slide cores), which confirms that the hook 2 and the mounting member 3 were simultaneously injection molded by a common mold device. The rotating part 41 is fixed to and supported by the tip of the shaft part 43. The shaft part 43 is rotatable in response to the rotation of the rotating part 41. The shaft part 43 has, for example, a circular cross section, but is not limited to this.

The hook 2 and the mounting member 3 can be arranged on the same plane (a plane that is perpendicular to the rotation axis AX1 and includes the rotation axis AX2) (see FIG. 2). In this plane, the hook 2 can rotate around the rotation axis AX1 (parallel to the thickness direction of the hook 2) relative to the mounting member 3, and vice versa. The hook 2 can also rotate around the rotation axis AX2 (perpendicular to the thickness direction of the hook 2) relative to the mounting member 3, and the hook 2 and the mounting member 3 can be arranged on different planes that are perpendicular to each other by the 90° rotation (see FIG. 3). Although not necessarily limited to this, the hook 2 can have two (or more) degrees of rotational freedom relative to the mounting member 3, which improves the usability of the hanging device 1. The same plane on which the hook 2 and the mounting member 3 are arranged is perpendicular to the thickness direction of the hook 2 and the thickness direction of the mounting member 3. That is, the plane is perpendicular to the thickness direction of the hook 2 and the thickness direction of the mounting member 3 when they are arranged so that the thickness directions of the hook 2 and the mounting member 3 are parallel to each other. The thickness direction can be understood to correspond to the front-to-rear direction of the hanging device 1 shown in Figure 1.

A rotating part 41 can be provided on the connecting part 32 of the mounting member 3, and a receiving part 42 can be provided on the hook base 21 of the hook 2. In this case, the hook base 21 and the connecting part 32 can be configured as follows. The hook base 21 (receiving part 42) has first and second opposing parts 47, 48 arranged opposite each other. A part (first part) of the space between the first and second opposing parts 47, 48 functions as a receiving groove for receiving the rotating part 41, and another part (second part) functions as a groove 46 for the movement of the shaft part 43. Through holes 47j, 48j for partially receiving the rotating part 41 can be provided in each opposing part 47, 48. According to this configuration, a mold device for simultaneously injection-molding the hook 2 and the mounting member 3 with the same mold device can be appropriately constructed. The through holes 47j, 48j penetrate the opposing parts 47, 48 in the thickness direction of the opposing parts 47, 48. As an alternative to the through holes 47j, 48j in the opposing parts 47, 48, a recess can be provided to partially accommodate the rotating part 41.

The rotation of the hook 2 relative to the mounting member 3 reduces the overall size of the hanging device 1 (see FIG. 4). The free rotation or pivoting of the hook 2 relative to the mounting member 3 improves the ease of use of the hanging device 1. In this regard, when the hanging device 1 is not being used, there is a demand to maintain the overall size of the hanging device 1 small, and there is also a demand to inform the user who operates the hook 2 that the hook 2 has reached a predetermined position. From either or both of these perspectives, in some cases, a mechanism is employed that holds the position of the hook 2 relative to the mounting member 3 simply or temporarily, i.e., releasably from that position. Specifically, a narrow portion 46j with a reduced groove width is provided in the groove 46 (see FIG. 5). This allows the relative positional relationship between the hook 2 and the mounting member 3 to be maintained in a certain state, or allows the user to be informed that the position has been reached.

In FIG. 5, the narrow portion 46j is provided to position the mounting member 3 adjacent to the hook tip 22. In order for the shaft portion 43 to pass through the narrow portion 46j, the hook 2 must be operated more consciously, which allows the hook 2 to be easily or temporarily held in a desired position, or the user can be notified that the hook 2 has reached a desired position. The narrow portion 46j can be formed by arranging a pair of protrusions 87, 88 facing each other on the facing surfaces of the facing portions 47, 48, but it is also possible to use only one protrusion. Each protrusion 87, 88 can be a single wavy protrusion extending from the outer periphery of the facing surfaces of the facing portions 47, 48 toward the inside (e.g., through holes 47j, 48j). The narrow portion 46j divides the groove 46 into a first groove region 46p and a second groove region 46q. The shaft portion 43 may be rotatable about its axial direction while being received in the first groove region 46p of the groove 46, thereby further increasing the degree of freedom of deformation of the hanging device 1. In this case, it is advisable to make the first groove region 46p (slightly) larger than the cross-sectional area of the shaft portion 43.

The groove 46 can have one end 46e that narrows stepwise or continuously on the hook tip 22 side (see FIG. 5), which prevents cracks from occurring in the hook 2 (e.g., the opposing portions 47, 48) due to the force that the shaft portion 43 exerts on the first and second opposing portions 47, 48. The shaft portion 43 has a circular cross section, but is not limited to this cross-sectional shape. The shaft portion 43 cannot enter the one end 46e of the groove 46, and the one end 46e of the groove 46 has a width that is less than the maximum diameter or width of the shaft portion 43.

A non-limiting example of the use of the hanging device 1 will be described with reference to Figs. 6 and 7. The object to be hung 9 is, for example, a portable or travel-use expandable glove compartment, but is not limited thereto and may be various other items (typically lightweight items weighing 1 kg or less) such as a board with a mirror attached. When the hanging device 1 is attached to the object to be hung 9 as shown in Fig. 6, the object to be hung 9 can be hung from the pole 8 (via the hanging device 1) by hanging the hook 2 on the pole 8 or the like shown by the dashed line in Fig. 6. When the object to be hung 9 does not need to be hung, the hanging device 1 can be stored in the object to be hung 9 as shown in Fig. 7.

When the main body 31 is D-shaped, the attachment strap 92 can be inserted through the ring of the main body 31 and sewn to the fabric material 91 of the hanging device 1 at both sides. In this way, the main body 31 of the mounting member 3 is firmly attached to the object to be hung 9. The main body 31 can take a first position (Figure 6) in which it is laid down so as to straddle the side edge 93 of the object to be hung 9, and a second position (Figure 7) in which it is laid down on the opposite side to the first position. The first position of the main body 31 is suitable for deploying the hook 2 from the object to be hung 9. The second position of the main body 31 is suitable for storing the hook 2 in the object to be hung 9.

The above-mentioned engagement between the pivoting part 41 and the receiving part 42 allows the hook 2 to rotate in the same plane relative to the mounting member 3 (see FIG. 6). By changing the main body part 31 from the second position to the first position and rotating the hook 2 clockwise, the hook 2 can be positioned away from the object to be hung 9, and the hook 2 can be hung on the pole 8. Note that, although it depends on the engagement state between the pivoting part 41 and the receiving part 42, the hook 2 can rotate relative to the mounting member 3 with the rotation axis AX2 as the center of rotation in the state shown in FIG. 6.

The present disclosure promotes miniaturization of the hanging device 1 when not hanging. For reference, when the hook 2 and the mounting member 3 are connected to each other by a chain, the hook 2 can move freely relative to the mounting member 3, but there is a problem in that the hook 2 moves freely even when the hanging device 1 is not being used to hang the object to be hung 9. Compared to this case, the present disclosure successfully achieves both ensuring the freedom of movement of the hook 2 when hanging and miniaturization of the hanging device 1 when not hanging. A more specific explanation will be given below with reference to the remaining drawings.

8 shows that a plurality of virtual lines are set for the hook 2, and FIG. 9 shows that a virtual line is set for the mounting member 3. As shown in FIG. 8, it is assumed that a first virtual line L1 extending from the hook base 21 (for example, a rotation axis AX1 (see also FIG. 2) perpendicular to the arrangement surface of the hook 2 and the mounting member 3) toward the bottom point 26 of the hook recess 23 is expressed by a synthesis of a first vector V1 extending in the depth direction of the hook recess 23 and a second vector V2 extending perpendicular to the first vector V1 from the tip of the first vector V1 to the bottom point 26 of the hook recess 23. Note that, from the viewpoint of clarity, the bottom point 26 of the hook recess 23 is set at the intersection of a virtual line L8 obtained by moving the virtual lines L4 and L5 set corresponding to the opening width of the hook opening 25 in parallel with the bottom surface of the hook recess 23, but it may be another position that can be said to be the bottom of the hook recess 23 sufficiently distant from the hook base 21. The virtual line L4 is set at a position corresponding to the maximum opening width of the hook opening 25. The imaginary line L5 is set at a position corresponding to the minimum opening width of the hook opening 25. The depth direction of the hook recess 23 is diagonally to the right in Figures 1 and 8, but other directions can also be used.

The second and third virtual lines L2, L3 parallel to the first vector V1 can be set to sandwich the hook base 21 and the hook tip 22. The second virtual line L2 is set with respect to the hook base 21, and the third virtual line L3 is set with respect to the hook tip 22. The second virtual line L2 contacts the outer surface of the hook base 21, and the third virtual line L3 contacts the outer surface of the hook tip 22. The second and third virtual lines L2, L3 can be tangents to an imaginary circle C1 that determines the curved shape of the outer surface 2b of the hook 2.

The hook 2 can have a side surface 29 that extends flat along the second imaginary line L2. The hook recess 23 also has a width that increases and then decreases with distance from the hook opening 25, as represented by imaginary lines L5-L7 parallel to imaginary lines L4, L5. This is also a consequence of the J-shaped extension of the inner side surface 2a of the hook 2. With respect to the mounting member 3, an imaginary line L9 can be assigned to the extension direction of the rod portion 5, as shown in FIG. 9.

When the hook 2 and the mounting member 3 are arranged on the same plane, either the hook 2 or the mounting member 3 can rotate relative to the other such that the mounting member 3 rotates from a position spaced from the hook tip 22 (see FIG. 10) through an intermediate position (see FIG. 11) to an adjacent position (see FIG. 12). During this entire process, the mounting member 3 does not cross the third imaginary line L3. This promotes miniaturization of the hanging device 1, particularly when the hanging device 1 is not being used to hang the object 9 to be hung.

In addition, in the separated position (Figure 10), the hook base 21 is sandwiched between the mounting member 3 and the hook tip 22. In the intermediate position (Figure 11), the hook base 21 is not sandwiched between the mounting member 3 and the hook tip 22. In the adjacent position (Figure 12), the mounting member 3 is positioned closer to the hook tip 22 compared to the separated and intermediate positions described above.

The fact that the mounting member 3 does not intersect with the third imaginary line L3 means that the hook 2 does not intersect with the side edge 93 when the hook 2 is rotated from the broken line position to the solid line position in FIG. 7. If an element of the slide fastener (e.g., a coil element, a metal element or a resin element, a ceramic element) is arranged on the side edge 93, interference between this and the hook 2 is avoided.

As shown in FIG. 12, the mounting member 3 can cross a fourth virtual line L4 that is set at a position corresponding to the maximum opening width of the hook opening 25. Additionally or alternatively, the mounting member 3 can cross a fifth virtual line L5 that is set at a position corresponding to the minimum opening width of the hook opening 25. That is, the hook base 21 and the connecting portion 32 are configured so that the hanging device 1 can be in this state. This promotes miniaturization of the hanging device 1 when it is not being used to hang the object 9 to be hung.

The length of the groove 46 can also be described as being set so that the mounting member 3 can cross the fourth or fifth virtual line L4, L5 when either the hook 2 or the mounting member 3 is rotated relative to the other so that the mounting member 3 rotates toward the hook tip 22 while the hook 2 and the mounting member 3 are arranged on the same plane.

One of the first and second arc-shaped portions 61, 62 may cross the fourth or fifth imaginary line L4, L5 set at a position corresponding to the maximum or minimum opening width of the hook opening 25. Additionally or alternatively, the rod portion 5 may be oriented parallel to the second and third imaginary lines L2, L3. That is, the hook base 21 and the connecting portion 32 are configured, or the length of the groove 46 is set, so that the hanging device 1 can be in this state. This facilitates miniaturization of the hanging device 1 when it is not being used to hang the object 9 to be hung.

As can be seen from FIG. 13, the mounting member 3 can enter the hook opening 25 (or the hook recess 23 via the hook opening 25) from the first arc-shaped portion 61 or the second arc-shaped portion 62. When the hook 2 and the mounting member 3 are arranged on different planes that are perpendicular to each other (see FIG. 3), the entire mounting member 3 can pass through the hook opening 25 and enter the hook recess 23. In other words, the entire mounting member 3 can be positioned on the hook recess 23 side of the imaginary line L4.

The mounting member 3 is simply positioned and held in the position shown in FIG. 14. This is the result of the shaft portion 43 passing through the narrow portion 46j as described above (see also FIG. 15).

As shown in FIG. 16, assuming that a virtual perfect circle C2 is set to define the curved shape of the inner surface 2a of the hook 2, the mounting member 3 (e.g., the first arc-shaped portion 61 or the second arc-shaped portion 62) can intersect with the virtual perfect circle C2. In other words, the hook base 21 and the connecting portion 32 are configured, or the length of the groove 46 is set, so that the hanging device 1 can be in this state.

Just to be clear, as is clear from FIG. 7, when the main body 31 of the mounting member 3 is attached to the object to be hung 9, the hook 2 can rotate with respect to the mounting member 3 so that the second and third imaginary lines L2, L3 are oriented parallel to the linearly extending side edge 93 of the object to be hung 9. The side edge 93 is in a position to be straddled by the hook 2, and the mounting member 3 can be positioned above it as an option.

Figures 17 and 18 show an embodiment in which the shape of the hook 2 is not a perfect circle but is elliptical. Even in such a case, the same effect as described above can be obtained as long as it does not contradict the above explanation.

In FIG. 17, a virtual ellipse C3 is shown as an alternative to the virtual circle C1. A first virtual line L1 extending from the hook base 21 (rotation axis AX1) toward the bottom point 26 of the hook recess 23 is represented by the combination of a first vector V1 extending in the depth direction of the hook recess 23 and a second vector V2 extending perpendicular to the first vector V1 from the tip of the first vector V1 to the bottom point 26 of the hook recess 23.

In FIG. 18, a virtual ellipse C4 is illustrated as an alternative to the virtual circle C2, and the mounting member 3 can intersect with the virtual ellipse C4. As shown in FIGS. 17 and 18, the shape of the hook 2 can be changed without departing from the spirit of this disclosure. Similarly, the mounting member 3 can be changed to another shape. To avoid repetition, further description with reference to FIGS. 17 and 18 will be omitted.

In FIG. 19, the outer peripheral surface of the shaft portion 43 of the mounting member 3 is provided with a protrusion 49 that can contact the protrusions 87, 88 provided on the receiving portion 42 of the hook base 21 to form the narrow width portion 46j. The protrusion 49 is provided to protrude radially outward from the shaft portion 43. As a result, the shaft portion 43 is provided with small diameter portions 71, 72 and a large diameter portion 73. The large diameter portion 73 is a portion formed by providing the above-mentioned protrusion 49 on the outer peripheral surface of the shaft portion 43, and is provided between the small diameter portions 71, 72. The diameter of the large diameter portion 73 is, for example, within a range of 1.05 to 1.4 times the diameter of the small diameter portions 71, 72. In FIG. 19, the large diameter portion 73 is provided as a protrusion protruding radially outward, but this is not limited to this, and one of the small diameter portions 71 in FIG. 19 may be formed to have the same diameter as the large diameter portion 73. In other words, one of the two small diameter sections 71, 72 can be omitted.

As shown in FIG. 20, when the shaft portion 43 is inserted into the narrow portion 46j of the groove 46, the protrusion 49 (and the large diameter portion 73) of the shaft portion 43 comes into contact with the protrusions 87, 88 provided on the opposing portions 47, 48 to form the narrow portion 46j of the groove 46 (note that only one protrusion may be provided for the narrow portion 46j instead of two protrusions). When the protrusion 49 (and the large diameter portion 73) of the shaft portion 43 overcomes the protrusions 87, 88, the force required to rotate the mounting member 3 increases instantaneously, so that the user can be notified that the mounting member 3 has reached a predetermined position (for example, the above-mentioned first groove region 46p). When the protrusion 49 (and the large diameter portion 73) is provided on the shaft portion 43 in this way, the function of informing the user can be maintained even if the remaining portion of the shaft portion 43 is reduced in diameter (narrowed). Note that it is preferable to make the first groove region 46p (slightly) larger than the cross-sectional area of the large diameter portion 73.

A wall 81 may be provided on the opposing surface of each opposing portion 47, 48 to partially or entirely surround the open end of the through hole 47j, 48j, and the above-mentioned protrusions 87, 88 may be connected to this wall 81 (see FIG. 21). This prevents damage to the portion of the slide core used to mold the protrusions 87, 88 due to collision with another slide core. Although not clearly shown in FIG. 21, the protrusion 87 is also provided on the opposing surface of the opposing portion 47, connected to a wall (not shown) surrounding the open end of the through hole 47j. The wall 81 is a C- or U-shaped portion with an opening facing the opposite side to the first vector V1 described above, but should not be limited to this.
