Description

  The present invention relates to a vise, and more particularly to a vise structure applied to a fishing rod holder that detachably holds a fishing rod on a ship rim.

  Generally, in boat fishing, a fishing rod is held by a fishing rod holder, and this fishing rod holder is fixed to a ship edge via a vise (see, for example, Patent Document 1 and Patent Document 2). The vise applied to a fishing rod holder is generally a C-shaped clamp (so-called “Shakoman”). The C-shaped clamp has a C-shaped frame and a fastening shaft. A shaft holding portion is formed at one end portion of the frame, and a fixed jaw portion is formed at the other end portion facing the one end portion. The fastening shaft is screwed into the shaft holding portion, and a movable jaw is formed at the tip of the fastening shaft. A handle is provided at the proximal end of the fastening shaft. By operating this handle, the fastening shaft moves relative to the frame, and the movable jaw comes in contact with and separates from the fixed jaw.

  Usually, a liner to which a vise is attached is installed at the ship's edge. The C-shaped clamp holds this liner. That is, the movable jaw is pressed against the lower surface of the liner by operating the handle while the fixed jaw is in contact with the upper surface of the liner. The liner is sandwiched between the fixed jaw and the movable jaw, whereby the C-shaped clamp is fixed to the liner.

  By the way, when a large fish hits, the fishing rod is pulled with great force. When a particularly hit fish swims along the ship's edge, the fishing rod, fishing rod holder and vise are pulled in the direction along the ship's edge. Since the fixed jaw and the movable jaw sandwich the upper and lower surfaces of the ship's edge, if a large force acts on the C-shaped clamp in the same direction, the C-shaped clamp can be easily rotated around the fastening shaft. There is a risk that it will come off the ship's edge. For this reason, conventionally, measures have been taken to increase the area of the fixed jaw or to separately provide an auxiliary tool that comes into contact with the upper surface of the ship edge on the C-shaped clamp.

Japanese Patent No. 4484786 Japanese Patent No. 4240334

  However, even if such measures are taken, after all, the contact area between the C-shaped clamp and the upper surface of the ship's upper surface is only enlarged, so that if the fishing rod is pulled strongly along the ship's edge, the C-shaped clamp will come off. It is expected that. In order to solve this problem, a vise equipped with two C-shaped clamps has been proposed. This vise has two fixed jaws and two movable jaws, and sandwiches the side surfaces of the liner (the outer side surface and the inner side surface of the ship).

  This vise is securely fixed to the liner even when a force along the ship's edge is applied. However, this vise has a new problem that the frame becomes large and has two fastening shafts, so that the weight becomes very large and the manufacturing cost increases.

  The present invention has been made based on such a background, and the object of the present invention is to apply an external force or even in a different direction (typically along the ship's edge) different from a predetermined direction (typically the tightening direction). It is to provide a vise that can be securely fixed to an object (typically a ship's edge) even when force is applied.

  (1) In the vise according to the present invention, a pair of hinge parts are formed by pivotally connecting ends of a pair of C-shaped frames, and an angle formed by the C-shaped frames is within a predetermined range. And a fastening shaft that is screwed into one of the hinge portions and that contacts and separates from the other hinge portion.

  The vise according to the present invention is attached to an object (typically a ship rim used for boat fishing) as follows. The main body has a pair of C-shaped frames, and each C-shaped frame can be opened and closed in a butterfly shape. A C-shaped frame opened at a certain angle is arranged on the ship's edge. Specifically, one hinge portion of the pair is brought into contact with the upper surface of the ship edge, and the other hinge portion is opposed to the lower surface of the ship edge. In other words, each C-shaped frame goes around the inner surface from the upper surface of the ship edge and reaches the lower surface. At this time, since each C-shaped frame is opened at a constant angle, each C-shaped frame comes into contact with the inner surface of the ship edge with a predetermined span. Then, when the tightening shaft is operated, the tightening shaft approaches one of the hinge portions, and the ship edge is sandwiched between the two. Thereby, a main body is fixed to a ship's rim. Since each C-shaped frame is in contact with the inner surface of the ship's edge, even if a couple of forces around the fastening shaft acts on the main body, the main body receives the reaction force from the inner surface and rotates. Never do.

  (2) The C-shaped frame is provided with a pair of arms opposed to each other along a predetermined direction, a hinge piece that is provided at a base end of each arm, and that constitutes the hinge portion, and extends along the predetermined direction. And a leg for connecting the tip portions of the arms.

  According to this configuration, the pair of hinge portions is formed by engaging the hinge piece of one C-shaped frame with the hinge piece of the other C-shaped frame. The arms are continuous with the hinge pieces, but the arms are opposed to each other. Therefore, the legs connecting the arms are arranged so as to intersect the arms. Therefore, if the C-shaped frame opened at a certain angle sandwiches the upper and lower surfaces of the ship edge, the legs easily come into contact with the inner surface of the ship edge.

  (3) It is preferable that the tip portion of the arm is provided with a cover for relaxing stress concentration generated in the leg.

  In this configuration, both ends of the leg are covered and reinforced by the cover. Therefore, even when a large couple around the fastening shaft acts on the main body and a large reaction force acts on the leg from the inner surface, stress concentration generated on the leg is alleviated.

  (4) It is preferable that the hinge piece includes a stopper that regulates the angle formed by the C-shaped frames to be within a certain range.

  In this configuration, the work vehicle can easily make the angle formed by the pair of C-shaped frames constant. That is, it is easy to securely fix the main body to the ship's edge.

  (5) It is preferable that the leg is made of a straight rod and is detachably provided at the tip of the arm.

  With this configuration, the leg structure is simple and the manufacturing cost of the vise is reduced. In addition, for example, by preparing a plurality of legs having different lengths, the length of the legs can be easily adjusted according to the size of the ship's edge.

  (6) It is preferable that the hinge portion includes a biasing member that elastically biases the C-shaped frame so that an angle formed by the C-shaped frames is increased.

  According to this configuration, since the pair of C-shaped frames automatically opens, it is easier to fix the main body to the ship's rim.

  (7) Further, the vise according to the present invention is a type that can mount a fishing rod holder and is attached to a ship's rim. This vise has a C-shaped frame that engages the ship's rim and a clamping shaft provided on the C-shaped frame. A contact surface is formed on the upper end side of the C-shaped frame so as to be in contact with the upper surface of the ship rim, and the fastening shaft is contacted with and separated from the lower surface of the C-shaped frame with respect to the contact surface. A seat portion into which the fastening shaft is screwed is formed. The C-shaped frame is formed with a rotation restricting surface facing the inner side surface along the inner side surface of the ship edge while the ship edge is sandwiched between the tightening shaft and the contact surface.

  The vise according to the present invention is attached to the ship's edge (typically, the ship's edge used for boat fishing) as follows. The contact surface of the C-shaped frame is in contact with the upper surface of the ship edge. At this time, the C-shaped frame goes around the inner surface from the upper surface of the ship edge and reaches the lower surface. In this state, the tightening shaft is operated. This fastening shaft is screwed into the seat portion of the C-shaped frame, and is brought into and out of contact with the contact surface by being rotated. That is, when the tightening shaft is operated, the tightening shaft approaches the abutment surface, and the ship edge is sandwiched between the two. The C-shaped frame has a rotation restricting surface that abuts the inner surface of the ship's edge. Therefore, even if a couple or the like centering on the tightening shaft acts on the C-shaped frame, the C-shaped frame does not rotate by receiving a reaction force from the inner side surface.

  (8) It is preferable that the portion of the C-shaped frame where the rotation restricting surface is formed is formed thin.

  According to this configuration, the weight of the C-shaped frame can be reduced.

  According to the present invention, even when an external force or couple acts on the vise in a direction along the ship's edge while the vise is fixed to the object (the ship's edge, etc.), the external force or couple is It will be balanced with the reaction force from the inner surface of the. Accordingly, the vise is securely fixed to the object.

  The vise 10 is used during fishing (typically boat fishing) and is generally fixed to the rim. The vise 10 includes a mount portion 17 described later, and a fishing rod holder is placed on and fixed to the mount portion 17. The fishing rod holder holds a fishing rod and supports a fisherman in actual fishing on a boat. The vise 10 includes a main body 13 having a pair of C-shaped frames 11 and 12 and a fastening shaft 14 provided on the main body 13. The pair of C-shaped frames 11 and 12 are combined with each other, and a pair of hinge portions 15 and 16 are formed. The hinge portions 15 and 16 face each other in the direction indicated by the arrow 23 in FIG. 1 (vertical direction: corresponding to “predetermined direction” described in claims).

  The fastening shaft 14 is screwed into the lower hinge portion 16. The tightening shaft 14 cooperates with the hinge portion 15 to sandwich the ship edge as will be described later. This ensures that the vise 10 is fixed to the ship edge. A mount portion 17 on which the fishing rod holder is placed is formed on the upper surface of the C-shaped frame 11. The shape or structure of the mount portion 17 corresponds to the shape of the fishing rod holder to be mounted, and is not particularly limited. Further, a concave portion 18 similar to the mount portion 17 is formed on the lower surface of the C-shaped frame 12 because the C-shaped frame 11 and the C-shaped frame 12 are formed of common parts.

  A feature of the vise 10 according to the present embodiment is that the pair of C-shaped frames 11 and 12 are relatively rotated around the hinge portions 15 and 16 so that the posture changes in a so-called butterfly shape, and When the pair of C-shaped frames 11 and 12 are attached to the ship's edge in a state where they are separated from each other (as shown in FIG. 1), the legs 21 and 22 of the C-shaped frames 11 and 12 are the inner surface 19 of the ship's edge 20 (see FIG. 10). ). As the legs 21 and 22 abut against the inner side surface 19 of the ship edge 20 as described above, the vise 10 is firmly fixed to the ship edge 20 as described later.

  The C-shaped frame 11 constituting the main body 13 has a pair of arms 24 and 25 and a leg 21 connecting them. The arms 24 and 25 are disposed so as to face each other in the vertical direction (the direction indicated by the arrow 23). Moreover, the leg 21 is extended along the up-down direction.

  The central portion of the arm 24 is formed in a prismatic shape, and a plurality of (three in this embodiment) concave portions 33 are provided. The recess 33 is provided to reduce the weight of the arm 24. A hinge piece 26 is formed at the proximal end of the arm 24, and a leg holding portion 27 is formed at the distal end of the arm 24. These are preferably integrally formed of resin or metal. The hinge piece 26 is formed in a substantially disk shape. The mount portion 17 is formed on the upper surface of the hinge piece 26, and the engaging recess 28 is formed on the lower surface side. As will be described later, the engaging recess 28 engages with the hinge piece (35) of the C-shaped frame 12. A through-hole 29 that penetrates in the vertical direction is provided at the center of the hinge piece 26. A step portion 30 (corresponding to a “stopper” described in claims) is provided on the outer edge of the hinge piece 26. As shown in FIGS. 4 and 5, the step portion 30 is formed so as to protrude outward in the radial direction from the arc-shaped portion of the hinge piece 26. The effect by providing this step part 30 is mentioned later.

  The leg holding part 27 is a substantially cylindrical member. The leg holding part 27 accommodates and holds the upper end part of the leg 21, and the leg 21 is fastened to the leg holding part 27 by a bolt 31. A cover 32 is provided at the lower end of the leg holder 27. The cover 32 is formed integrally with the leg holding portion 27 and is formed in a semi-cylindrical shape that is divided into two along the axial direction. The inner diameter of the cover 32 corresponds to the outer diameter of the leg 21, and the leg 21 is reinforced by the cover 32. The effect by providing this cover 32 is mentioned later.

  The central portion of the arm 25 is also formed in a prismatic shape, and a plurality of (three in this embodiment) concave portions 33 are provided for the purpose of weight reduction. A leg holding part 34 is provided at the tip of the arm 25. The leg holding portion 34 has the same configuration as the leg holding portion 27 provided on the arm 24, and stores and holds the lower end portion of the leg 21 and reinforces the leg 21 with a cover 32. As shown in FIG. 5, the lower end portion of the leg 21 is fastened to the leg holding portion 34 by a bolt 31. A hinge piece 35 is formed at the base end of the arm 25 and is formed integrally with the arm 25 together with the leg holding portion 34.

  The hinge piece 35 is formed in a substantially disc shape. An engaging recess 36 is formed on the lower surface side of the hinge piece 35. As will be described later, the engaging recess 36 engages with the hinge piece (26) of the C-shaped frame 12. A through-hole 37 that penetrates in the vertical direction (the direction indicated by the arrow 23) is provided at the center of the hinge piece 35. A step portion 38 (corresponding to a “stopper” described in claims) is provided on the outer edge of the hinge piece 35. Similar to the step portion 30, the step portion 38 is formed so as to protrude radially outward from the arc-shaped portion of the hinge piece 35. The effect by providing this step part 38 is mentioned later.

  As shown in FIGS. 1 and 2, the C-shaped frame 12 is connected to the C-shaped frame 11. The C-shaped frame 12 has the same shape as the C-shaped frame 11. The C-shaped frame 12 looks like the C-shaped frame 11 turned upside down. That is, the hinge piece 35 of the C-shaped frame 12 is fitted to the hinge piece 26 of the C-shaped frame 11 to constitute the hinge portion 15, and the hinge piece 26 of the C-shaped frame 12 is fitted to the hinge piece 35 of the C-shaped frame 11. Thus, the hinge portion 16 is configured.

  FIG. 6 is an exploded perspective view of the hinge portion 15. FIG. 7 is a cross-sectional view of the hinge portion 15, and FIG. 8 is a cross-sectional view of the hinge portion 16.

  The internal structure of the hinge portion 15 is as shown in FIG. As described above (see FIG. 5), the engagement recess 28 is formed in the hinge piece 26, and the engagement recess 36 is formed in the hinge piece 35. The engaging recess 28 and the engaging recess 36 are arranged to face each other, and a bush 39 is fitted between them. That is, the bush 39 is fitted between the engagement recesses 28 and 36, and the hinge piece 26 and the hinge piece 35 are relatively rotated with the bush 39 interposed therebetween. The bush 39 is fixed to the hinge piece 26 side by a pin 40. A torsion coil spring 41 (corresponding to an “urging member” recited in the claims) is disposed inside the bush 39. Both ends of the torsion coil spring 41 are fixed to the hinge piece 26 and the hinge piece 35, so that the hinge portion 15 opens the arm 24 and the arm 25, that is, an angle θ formed by the both (see FIG. 1). (See) is elastically biased so as to increase. Further, as shown in FIG. 7, the coupling pin 42 is fitted into the through holes 29 and 37, and thereby the hinge piece 26 and the hinge piece 35 are connected.

  As shown in FIG. 8, the internal structure of the hinge portion 16 is the same as the internal structure of the hinge portion 15. However, in the hinge part 16, a screw hole 43 is formed in the coupling pin 42 fitted in the through holes 29 and 37. The tightening shaft 14 is engaged with the screw hole 43. Although not shown, a male screw is formed on the fastening shaft 14 (see FIGS. 1 and 2), and this is screwed into the screw hole 43. When the tightening shaft 14 is rotated, the tightening shaft 14 slides in the vertical direction, and the contact plate 44 contacts and separates from the hinge portion 15.

  9 is a cross-sectional view taken along line IX-IX in FIG. The figure shows the mounting structure of the legs 22.

  The leg 22 is formed in a straight elongated cylindrical shape. The legs 22 can be made of resin or metal. The leg holding portion 27 provided on the arm 24 has a bolt housing chamber 45 formed on the lower side and a leg housing chamber 46 formed on the upper side. Similarly, the leg holding portion 34 provided on the arm 25 has a leg accommodating chamber 47 formed on the lower side and a bolt accommodating chamber 48 formed on the upper side. Both ends of the leg 22 are fitted into the leg accommodating chambers 46 and 47. The bolt 31 is screwed into the leg 22 while being accommodated in the bolt accommodating chambers 45 and 48. Thereby, the leg 22 is fixed to the leg holding portions 34 and 27. That is, the leg 22 is detachable with respect to the leg holding portions 34 and 27. Note that the leg 21 is the same member as the leg 22 and is detachably attached to the leg holding portions 27 and 34 by bolts 31. In addition, the shape of the legs 22 and 21 is not limited to a straight rod-shaped member, and may be another shape.

  In the present embodiment, the end surfaces of the legs 21 and 22 are fastened to the leg holders 27 and 34 by the bolts 31, but the legs 21 and 22 may be fixed to the leg holders 27 and 34 by other methods. For example, the slits are formed in the axial direction of the leg holders 27 and 34 so that the inner diameter thereof is elastically expanded and contracted by the elastic deformation of the leg holders 27 and 34, and the slits are opposed to each other. A pair of flanges may be formed on the leg holding portions 27 and 34. In that case, a bolt is inserted into the pair of flanges, and a nut is screwed into the flange, whereby the inner diameters of the leg holding portions 27 and 34 are reduced via the pair of flanges. As a result, the legs 21 and 22 are tightened. And fixed to the leg holders 27 and 34. By fixing the legs 21 and 22 with such a structure, there is an advantage that the deformation amount when an external force acts on the legs 21 and 22 can be suppressed.

  The vise 10 according to the present embodiment is attached to the ship edge in the following manner.

  As shown in FIG. 1, the angle θ formed by the pair of C-shaped frames 11 and 12 changes, and the main body 13 opens and closes in a butterfly shape. C-shaped frames 11 and 12 opened at a constant angle θ are arranged on the ship's edge.

  FIG. 10 is a view showing a state where the vise 10 is attached to the ship rim 20. The figure is a bottom view of the vise 10.

  The lower surface of the hinge portion 15 (see FIG. 1) is brought into contact with the upper surface of the ship edge 20, and the hinge portion 16 is opposed to the lower surface of the ship edge 20 as shown in FIG. In other words, the C-shaped frames 11 and 12 go around the inner surface 19 from the upper surface of the ship edge 20 and reach the lower surface. At this time, since the C-shaped frames 11 and 12 intersect at an angle θ, each C-shaped frame 11 and 12 abuts the inner side surface 19 of the ship edge with a predetermined span S. When the tightening shaft 14 is operated, the contact plate 44 cooperates with the hinge portion 15 to sandwich the ship edge 20. Since the tightening shaft 14 includes the handle 50, the angler can easily operate the tightening shaft 14. When the tightening shaft 14 is tightened, the vise 10 comes into contact with the upper and lower surfaces and the front side surface 19 of the ship edge 20. Thus, since the vise 10 abuts on the three surfaces of the ship edge 20, even if a couple or the like around the fastening shaft 14 acts on the vise 10, the vise 10 It does not rotate by receiving a reaction force from the inner side surface 19 of 20 and is securely fixed to the ship edge 20.

  In the present embodiment, each of the C-shaped frames 11 and 12 has arms 24 and 25 that are opposed to each other in the vertical direction (in the direction of the arrow 23), and the legs 21 that connect the arms 24 and 25 in the vertical direction. 22 is provided. In other words, the legs 21 and 22 that connect the arms 24 and 25 are arranged so as to intersect the arms 24 and 25. Therefore, if the vise 10 sandwiches the upper and lower surfaces of the ship edge 20 with the C-shaped frames 11 and 12 opened at an angle θ as described above, the legs 21 and 22 can be easily attached to the inside of the ship edge 20. It comes into contact with the side surface 19. That is, the vise 10 can easily come into contact with the three surfaces of the ship rim 20.

  By the way, as shown in FIG. 10, when the vise 10 is attached to the ship edge 20 and a couple of forces around the fastening shaft 14 acts or a twist occurs around the fastening shaft 14, the leg 21 , 22 is subjected to a large reaction force or external force. In the present embodiment, since the leg holding portions 27 and 34 are provided with the cover 32, it is possible to prevent a large stress from being generated in the legs 21 and 22. However, the cover 32 may be omitted if the legs 21 and 22 have sufficient mechanical strength.

  In the present embodiment, as shown in FIGS. 4 and 5, step portions 30 and 38 are formed on the hinge pieces 15 and 16. By providing the stepped portions 30 and 38, when the vise 10 is opened in a butterfly shape, the stepped portion 30 (38) is fixed to the arms 25 and 24 of the opposing C-shaped frame 12 as shown in FIG. Abuts the site. For this reason, the angle θ between the C-shaped frames 11 and 12 is regulated to be within a certain range. That is, the angle θ formed by the C-shaped frames 11 and 12 does not become too large. Thereby, the operation | work which fixes the vise 10 to the ship's edge 20 becomes easy.

  Further, since the legs 21 and 22 are made of a straight cylindrical member, the vise 10 that abuts the three surfaces with respect to the ship edge 20 with a simple structure is constructed at low cost. In addition, since the legs 21 and 22 are detachable, for example, by preparing a plurality of legs having different lengths, the lengths of the legs 21 and 22 can be easily adjusted according to the size of the boat rim 20.

  In addition, as shown in FIG. 6, the hinge portions 15 and 16 incorporate the torsion coil spring 41, so that the C-shaped frames 11 and 12 are automatically opened until the angle θ between them is constant. Become. The angle θ at this time is appropriately changed by adjusting the position of the stepped portions 30 and 38. In the present embodiment, θ is set to 45 ° (degree). Therefore, there is an advantage that the work of fixing the vise 10 to the ship edge 20 becomes easier.

<Second Embodiment>

  FIG. 11 is a perspective view of a vise 60 according to the second embodiment of the present invention.

  The vise 60 according to the present embodiment includes a C-shaped frame 61 constituting a main body 63 and a fastening shaft 62 provided on the C-shaped frame 61. That is, the vise 60 according to the present embodiment differs from the vise 10 according to the first embodiment in that (1) the main body 63 is composed of a single C-shaped frame 61 and the hinge portions 15 and 16 (see FIG. (2) The top plate portion 64 of the C-shaped frame 61 is in contact with the upper surface of the ship rim 20 (see FIG. 10), (3) The bottom plate of the C-shaped frame 61 (4) In the first embodiment, the legs 21 and 22 (see FIG. 1) of the C-shaped frames 11 and 12 are the front side surface 19 of the ship edge 20. (Refer to FIG. 10), in this embodiment, the inner surface 67 (corresponding to the “rotation restricting surface” described in the claims) of the support column 66 is in contact with the front side surface 19 in this embodiment. It is a point.

  The C-shaped frame 61 is made of metal (typically stainless steel or titanium alloy), and includes a top plate portion 64, a bottom plate portion 65, and a column portion 66 as shown in FIG. The top plate portion 64 and the bottom plate portion 65 are plate-like members having a predetermined thickness, and both are arranged to face each other in the vertical direction. A lower surface 68 (corresponding to a “contact surface” described in the claims) of the top plate portion 64 contacts the upper surface of the ship edge 20.

  A seat portion 69 is formed on the bottom plate portion 65, and the fastening shaft 62 is screwed to the seat portion 69. The fastening shaft 62 has the same structure as the fastening shaft 14 according to the first embodiment, and is formed with a male screw (not shown). On the other hand, a female screw (not shown) is formed inside the seat portion 69, and the fastening shaft 62 is screwed into this female screw. A handle 50 is attached to the tightening shaft 62, and when the handle 50 is operated, the tightening shaft 62 is rotated. Thereby, the contact plate 44 provided at the tip of the fastening shaft 62 slides in the vertical direction.

  The support | pillar part 66 has a pair of prisms 71 and 72 in this embodiment. These intervals S correspond to the spans S of the legs 21 and 22 of the vise 10 according to the first embodiment. However, the spacing S between the prisms 71 and 72 can be appropriately changed. In the present embodiment, the pair of prisms 71 and 72 are formed on the support column 66. In other words, the main body 63 is formed by bending the flat plate into a C shape, and the top plate 64 and the support column. 66 and a part of the bottom plate portion 65 are cut in the vertical direction (the direction of the arrow 23), whereby the main body 63 is configured.

  The vise 60 according to the present embodiment is fixed to the ship edge 20 in the following manner. That is, the lower surface 68 of the C-shaped frame top plate portion 64 is brought into contact with the upper surface of the ship edge 20 (see FIG. 10). At this time, the C-shaped frame 61 is shaped to go around the inner surface 19 from the upper surface of the ship edge 20 and reach the lower surface. When the fastening shaft 62 is operated in this state, the ship edge 20 is sandwiched between the contact plate 44 and the top plate portion 64. The C-shaped frame 61 has prisms 71 and 72, and the inner surface 67 abuts against the inner surface 19 of the ship edge 20. In this way, since the vise 60 abuts on the three surfaces of the ship edge 20, even if a couple or the like around the fastening shaft 62 acts on the vise 60, the vise 60 It does not rotate by receiving a reaction force from the inner side surface 19 of 20 and is securely fixed to the ship edge 20.

  In the present embodiment, the thickness of the prisms 71 and 72, that is, the dimension B from the inner surface 67 to the rear surface 73 is designed to be small. In this way, the portion of the C-shaped frame 61 that contacts the inner side surface 19 is formed thin, so that the weight of the C-shaped frame 61 and the vise 60 can be reduced. However, for example, the C-shaped frame 61 may be formed by bending a metal flat plate into a C shape.
