Description

Technical Field

[0001] This invention relates to a handle and a pull handle set attached to a string.

Background Art

[0002] Conventionally, there is a handle that is attached to a string and used, as shown in, for example, Patent Document No. 1 and Patent Document No. 2 below. Regarding such a handle, in Patent Document 1 and the like, for example, it has been proposed to be used together with a wheeled bag or case that is widely used to facilitate carrying while pulling a heavy load. That is, when using this type of wheeled bag or the like on a flat and clean paved road surface, it is easy to carry while pulling, but when using it on a rough road surface such as a stone-paved road, there is a problem that it is difficult to carry because the road surface condition is directly transmitted to the pull handle of the bag or the like. On the other hand, by attaching a handle to the string connected to the bag or the like and pulling the handle, it can be expected to be easy to carry regardless of the road surface condition.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, regarding such a handle, it is useful to be able to change the position where the handle is fixed to the string, that is, to be able to adjust the length. On the other hand, it is important that the handle is firmly fixed to the string during use. It would be better if such a string length adjustment structure could be realized with a structure different from the conventional structure.

[0005] This invention was made in view of these points, and aims to provide a handle and pull tab set that can securely fasten a string and allow for adjustment of the string's length. [Means for solving the problem]

[0006] The handle of the first invention is a handle used attached to a string, and is configured to house a portion of the string inside so that the string passes through it, comprising a gripping portion that can be grasped by the user, and a fixing structure configured to be able to clamp the string inside the gripping portion, wherein the fixing structure has a gap in which the string is clamped in such a way that it is bent multiple times in a series of directions different from each other, and the handle is configured such that, depending on the shape of the gap, the gripping portion is either fixed to the string or released from being fixed to the string and the gripping portion is able to slide relative to the string.

[0007] With this configuration, the cord can be securely fixed by the fixing structure when in a fixed state, and the length of the cord can be adjusted when in a released state.

[0008] Furthermore, the handle of this second invention, compared to the first invention, has a fixing structure comprising a first fixing part and a second fixing part, the first fixing part having two or more plate-shaped first projections spaced apart from each other, the second fixing part having at least one plate-shaped second projection, the first fixing part and the second fixing part facing each other on the inside of the gripping part, and arranged such that at least one second projection fits into the groove between the first projections, and the portion between the first projection and the second projection is configured to be a gap into which a string can be held.

[0009] This configuration allows the cord to be securely and firmly fixed in a fixed state, and also allows for adjustment of the cord's length.

[0010] Furthermore, the handle of this third invention differs from that of the second invention in that the gripping portion is composed of a lower first member and an upper second member combined together, the first fixing portion is formed on the part of the first member facing the second member, and the second fixing portion is formed on the part of the second member facing the first fixing portion.

[0011] This configuration makes it relatively easy to manufacture a handle that can securely and firmly fasten a string.

[0012] Furthermore, the handle of this fourth invention, compared to the third invention, is equipped with a locking mechanism that maintains the combined state of the first and second members, and the gripping portion is rod-shaped and configured such that the angle of the second member relative to the first member can be changed when viewed from the longitudinal direction, even when the combined state of the first and second members is not maintained by the locking mechanism.

[0013] This configuration allows the locking mechanism to maintain a fixed state while also enabling a switch from a fixed state to an unlocked state.

[0014] Furthermore, the handle of this fifth invention, compared to the third invention, is equipped with a locking mechanism that maintains the combined state of the first member and the second member, and the gripping portion is rod-shaped, with the first member and the second member connected near one end in the longitudinal direction, and is configured such that the angle of the second member relative to the first member can be changed when the combined state of the first member and the second member is not maintained by the locking mechanism.

[0015] This configuration allows the locking mechanism to maintain a fixed state while also enabling a switch from a fixed state to an unlocked state.

[0016] Further, in the handle of the sixth invention, with respect to the second invention, one of the first fixing portion and the second fixing portion is displaceable in a direction approaching or separating from the other displaceable portion of the first fixing portion and the second fixing portion as a displacement portion, the displacement portion is at least displaceable with respect to the gripping portion, and a position changing portion that switches between a fixed state and a released state by changing the position of the displacement portion with respect to the displaceable portion is provided.

[0017] With such a configuration, a fixing structure can be provided while minimizing the influence on the appearance of the gripping portion.

[0018] Further, in the handle of the seventh invention, with respect to the sixth invention, the position changing portion has a knock mechanism configured to be pushed in by a user via an operation portion exposed to the outside from a part of the gripping portion, and the knock mechanism is configured to change the position of the displacement portion with respect to the displaceable portion when operated.

[0019] With such a configuration, the fixed state and the released state can be easily switched.

[0020] Further, the handle set of the eighth invention includes any one of the first to seventh handles and a string, and the handle is attachable to the string such that a part of the string is accommodated inside the gripping portion of the handle.

[0021] With such a configuration, the string can be firmly fixed by the fixing structure in the fixed state, and the length of the string can be adjusted in the released state.

Advantages of the Invention

[0022] According to the present invention, the string can be firmly fixed and the length of the string can be adjusted.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of the handle and the handle set using the same will be described with reference to the drawings. In the embodiments, components denoted by the same reference numerals are configured in the same manner or perform the same functions, and repeated descriptions may be omitted.

[0025] In the following explanation, the coordinates shown in the drawings are common to all drawings. The Z direction of the coordinates is perpendicular to the horizontal plane. The X direction is perpendicular to the Z direction, and the Y direction is perpendicular to both the Z and X directions. The Z direction may also be referred to as the up-down direction (the direction that is positive on the Z axis when viewed from the origin is up), the X direction as the front-back direction (the direction that is positive on the X axis when viewed from the origin is forward), and the Y direction as the left-right direction. In the following, we may indicate a certain direction to explain the shape and positional relationship of each part, but the indication of direction is merely for the convenience of explanation and does not limit the orientation or posture when using the handle, etc., according to the present invention. Furthermore, expressions indicating direction, or states such as horizontal, vertical, orthogonal, only indicate that they can be understood in a general way, and should not necessarily be interpreted strictly according to those expressions.

[0026] (Embodiment 1)

[0027] The outline of this embodiment is as follows: The handle has a gripping portion, and the string can be secured by a fixing structure provided inside the gripping portion. The fixing structure can secure the string by clamping it in a zigzag pattern by bending it in different directions.

[0028] In Embodiment 1, the gripping portion is composed of an upper and a lower member, and a fixing structure is formed by the protrusions and recesses formed on each member. The gripping portion is rod-shaped, and the upper member is rotatably connected to the lower member around a rotation axis along its longitudinal direction. By rotating the upper member relative to the lower member, it is possible to switch between a fixed state in which the string is clamped by the fixing structure and a released state in which the string is released.

[0029] The following describes the configuration of the handle and the pull handle set, which includes the handle and string.

[0030] Figure 1 is a perspective view showing a handle 1 according to Embodiment 1 of the present invention. Figure 2 is a front view of the handle 1 according to Embodiment 1. Figure 3 is a perspective view showing the handle 1 according to Embodiment 1 in the open state. Figure 4 is a cross-sectional view taken along line A-A in Figure 2. Figure 5 is a cross-sectional view taken along line BB in Figure 2.

[0031] In Figure 1, the dashed line shows an example of the arrangement of the string 90 used with the handle 1.

[0032] The string 90 is a linear member made using, for example, a thread made by twisting wires together, but it is not limited to any particular form. It can be considered to be any long, narrow shape that can be used for various purposes by attaching a handle or pull tab, such as ropes, cords, belts, straps, ribbons, or tapes. For example, long, narrow members made of leather or synthetic resin, or members cut into long, narrow strips from a sheet-like material, may or may not be considered as strings 90. Similarly, metal chains may or may not be considered as strings 90. The shape of the string 90 may be various shapes, such as a circular, elliptical, or rectangular cross-section, and it may have a hollow or solid structure. Furthermore, the flexibility of the string 90 can vary from hard to soft.

[0033] The handle 1 comprises a gripping portion 4 that the user can grasp and a fixing structure 6 provided inside the gripping portion 4. In this embodiment, the gripping portion 4 is configured to be rod-shaped overall. In the longitudinal direction of the handle 1 (left-right direction in the figure), one end may be called the first end 2 and the other end may be called the second end 3.

[0034] In this embodiment, the gripping portion 4 is broadly divided into two members, upper and lower, separated by a horizontal plane, and has a lower first member 10 and an upper second member 20. That is, the gripping portion 4 is constructed by combining the lower first member 10 and the upper second member 20 with each other.

[0035] Furthermore, the gripping portion 4 is provided with a first opening 31 and a second opening 32, which serve as openings for the string 90 to enter the gripping portion 4 from the outside. In this embodiment, the first opening 31 is formed at the first end 2 and the second end 3 of the first member 10, respectively. The second opening 32 is provided at the center of the front and the center of the back of the gripping portion 4, respectively. Note that the position and number of the first opening 31 and the second opening 32 are not limited to these. For example, there may be one first opening 31 and one second opening 32.

[0036] The gripping section 4 is provided with a first opening 31 and a second opening 32, which allow a portion of the string 90 to be housed inside while the string 90 passes through. That is, for example, the string 90 passes through the first opening 31 and is routed so as to pass through the first end 2 and second end 3 of the gripping section 4 from the outside to the inside. The first opening 31 is connected to a wiring section 33 inside the gripping section 4, and the string 90 is routed through the wiring section 33 until it reaches a predetermined position inside the gripping section 4, for example, around where the fixing structure 6 is provided. The string routed inside the gripping section 4 also passes through the second opening 32 and is routed so as to pass through the front of the gripping section 4 from the inside to the outside. A single string 90 can be set on the handle 1 in this way, housed inside the gripping section 4 between the first opening 31 and the second opening 32.

[0037] In this embodiment, the first member 10 and the second member 20 are rotatably connected to each other at a connecting portion 5 provided on the back. The connecting portion 5 is configured to have a rotation axis parallel to the longitudinal direction. That is, the second member 20 is rotatably connected to the first member 10 around a rotation axis along the longitudinal direction. In other words, the gripping portion 4 is configured such that, when the combined state of the first member 10 and the second member 20 is not maintained by the locking portion 70 as described later, the angle of the second member 20 relative to the first member 10 can be changed when viewed from the longitudinal direction.

[0038] In the following, as shown in Figure 1, the state in which the first member 10 and the second member 20 are combined to form a rod-shaped gripping portion 4 as a whole is sometimes referred to as the closed state. Furthermore, the state in which the second member 20 rotates relative to the first member 10 around the connecting portion 5 as the axis of rotation, as shown in Figure 3, is sometimes referred to as the open state. The degree of opening in the open state is not limited to the state shown in Figure 3. It is sufficient to say that the state in which the second member 20 has rotated relative to the first member 10 from the closed state is the open state.

[0039] The connecting portion 5 has a structure in which a projection formed on one of the first member 10 and the second member 20 fits into an engaging portion formed on the other, thereby providing rotatable support, but is not limited to this. The connecting portion 5 is provided at both ends of the first end 2 and the second end 3, and the first member 10 and the second member 20 are connected to each other in a so-called double-supported structure, but is not limited to this.

[0040] Furthermore, in this embodiment, the first member 10 and the second member 20 are configured to remain locked together by the locking mechanism 70. In other words, the handle 1 is equipped with a locking mechanism 70 that maintains the state in which the first member 10 and the second member 20 are locked together.

[0041] In this embodiment, the locking mechanism 70 is provided in two locations, on both the left and right sides. However, the locking mechanism 70 may be provided in only one location, or there may be more than one.

[0042] In this embodiment, the locking portion 70 is composed of an engaging portion 17 provided on the first member 10 side and an engaged portion 27 provided on the second member 20 side. By maintaining the state in which the engaging portion 17 is engaged with the engaged portion 27, the locking portion 70 is configured to maintain the gripping portion 4 in a closed state.

[0043] As shown in Figures 3 and 4, the engaging portion 17 has a beam-shaped flexible portion that protrudes upward and is configured to bend when force is applied, allowing its upper end to be displaceable in the front-rear direction. The engaged portion 27 has a hole configured so that the upper end of the engaging portion 17 is exposed on the surface of the gripping portion 4 when in the closed state. When viewed from above, the upper end of the engaging portion 17 overlaps with a part of the engaged portion 27, and this engagement of the engaging portion 17 with the engaged portion 27 prevents the second member 20 from being displaced upward relative to the first member 10. The engaging portion 17 and the engaged portion 27 constitute a so-called snap fit. When a force is applied by a user or the like that causes the upper end of the engaging portion 17 to bend backward, and the engagement of the engaging portion 17 with the engaged portion 27 is released, the second member 20 becomes rotatable so that it is displaced upward relative to the first member 10 and enters an open state.

[0044] Next, the fixing structure 6 will be described. As shown in Figure 5, the fixing structure 6 comprises a first fixing part 11 and a second fixing part 21. The first fixing part 11 is provided on the first member 10. The second fixing part 21 is provided on the second member 20. The first fixing part 11 and the second fixing part 21 are provided on the inside of the gripping part 4. That is, the first fixing part 11 is formed on the part of the first member 10 that faces the second member 20. Also, the second fixing part 21 is formed on the part of the second member 20 that faces the first fixing part 11. The first fixing part 11 and the second fixing part 21 are arranged to face each other vertically.

[0045] The fixing structure 6 is configured to allow the string 90 to be held between the first fixing part 11 and the second fixing part 21 inside the gripping part 4. The first fixing part 11 and the second fixing part 21 are configured to interlock with each other so as to form a gap 40 that holds the string 90 in a zigzag pattern.

[0046] As shown in Figure 3, the fixing structure 6 is located near the center of the gripping portion 4 in the longitudinal direction. However, it is not limited to this; the fixing structure 6 may be located in a different part of the gripping portion 4, or it may be provided over substantially the entire longitudinal area.

[0047] As shown in Figure 5, the first fixing portion 11 has two or more plate-shaped first projections 12 that are spaced apart from each other. In this embodiment, four first projections 12 are provided. Each first projection 12 is formed to protrude upward from near the outer surface of the gripping portion 4. The upper end of each first projection 12 is located above the portion of the first member 10 that forms the outer surface of the gripping portion 4 in the vertical direction. In this embodiment, each first projection 12 is formed in a flat plate shape that extends in the longitudinal direction. It can also be said that the first projections 12 are formed in a rib shape.

[0048] Two first protrusions 12 are provided on the front side of the gripping portion 4, and two first protrusions 12 are provided on the rear side. In this embodiment, the wire passage portion 33 is located in the front-to-rear center of the gripping portion 4, and two first protrusions 12 are provided between the wire passage portion 33 and the front second opening 32 in the front-to-rear direction. In addition, two first protrusions 12 are also provided between the wire passage portion 33 and the rear second opening 32.

[0049] A gap exists between two adjacent first protrusions 12 in the front-rear direction. This gap is called a valley 16.

[0050] The second fixing portion 21 has at least one plate-shaped second projection 22. In this embodiment, two second projections 22 are provided side by side with a gap between them. The second projections 22 are formed to protrude downward from near the outer surface of the gripping portion 4. The upper end of the second projection 22 is located below the portion of the second member 20 that forms the outer surface of the gripping portion 4 in the vertical direction. In this embodiment, each second projection 22 is formed in a flat plate shape extending in the longitudinal direction. It can also be said that the second projections 22 are formed in a rib shape.

[0051] One second projection 22 is provided on the front side of the center of the gripping portion 4 in the front-rear direction, and another second projection 22 is provided on the rear side. In other words, one second projection 22 is provided between the wire passage portion 33 and the front second opening 32 in the front-rear direction. Also, one second projection 22 is provided between the wire passage portion 33 and the rear second opening 32.

[0052] In this embodiment, there is a gap between the two second protrusions 22. Furthermore, there is a gap in the front-rear direction between each second protrusion 22 and the outer surface (sometimes called the outer shell) of the gripping portion 4 that is close to it. This gap is referred to here as the second valley portion 26.

[0053] Each first projection 12 and each second projection 22 are substantially parallel to each other when in the closed state. In the fixing structure 6, the area where the first fixing part 11 and the second fixing part 21 are close to each other (the area near the center in the vertical direction) is empty except for the first projection 12 and the second projection 22. In other words, the fixing structure 6 has a gap 40 formed by the first projection 12 and the second projection 22.

[0054] The first fixing part 11 and the second fixing part 21 are arranged such that, in the closed state, at least one second projection 22 fits into the groove 16 between the first projections 12. The area between the first projection 12 and the second projection 22 is configured to be a gap 40 into which the string 90 is held. In this embodiment, the foremost first projection 12 is arranged to fit into the second groove 26 between the second projection 22 and the outer shell. The rearmost first projection 12 is also arranged to fit into the second groove 26 between the second projection 22 and the outer shell.

[0055] The following describes an example of how the string 90 is fixed by the fixing structure 6.

[0056] Figure 6 shows an example of the state in which the string 90 is fixed by the fixing structure 6 in Embodiment 1. Figure 7 shows an example of the state in which the fixing structure 6 is released in Embodiment 1.

[0057] Figure 6 shows the fixed state in which the fixing structure 6 fixes the string 90, and Figure 7 shows the released state in which the fixing structure 6 releases the string 90. The fixed state can also be described as the state in which the gripping part 4 is fixed to the string 90. The released state can also be described as the state in which the gripping part 4 is released from being fixed to the string 90. In the fixed state, the gripping part 4 is not slidable relative to the string 90 (including cases where it is hardly slidable), but in the released state, the gripping part 4 becomes slidable relative to the string 90.

[0058] In this embodiment, the gripping portion 4 is fixed when it is in the closed position. It is also configured to be released when the gripping portion 4 is in the open position. The locking portion 70 allows it to remain in the fixed position.

[0059] As shown in Figure 6, the string 90 is positioned in the gap 40 inside the gripping portion 4. In this embodiment, at least one second projection 22 fits into the valley 16 between the first projections 12 from different directions, so the gap 40 is configured such that the string 90 is sandwiched in a zigzag pattern. That is, the gap 40 is configured such that the string 90 is sandwiched in a state in which it is bent multiple times in a series of directions from each other.

[0060] The following describes the case in which the cord 90 is routed so that it is pulled upward from the wiring section 33 at the location where the fixing structure 6 is provided and exits to the outside through the second opening 32 at the front. In this case, the cord 90 is bent multiple times in an alternating pattern in the vertical direction so as to avoid the two first protrusions 12 and the one second protrusion 22 located between the wiring section 33 and the second opening 32 at the front. More specifically, the cord 90 bends from the wiring section 33 toward the second opening 32 in the order of a first bend 41 bending downwards, a second bend 42 bending upwards, and a third bend 43 bending downwards.

[0061] Since the string 90 is sandwiched in such a way that it bends in multiple different directions, the string 90 is securely fixed to the gripping part 4 when it is in a fixed state.

[0062] When the gripping part 4 opens from this fixed state, the shape of the gap 40 changes. In other words, the state of being fixed or released changes depending on the change in the shape of the gap 40.

[0063] In other words, as shown in Figure 7, when the gripping part 4 opens, the second projection 22 is released from fitting into the groove 12 between the first projections 12, and the gap 40 between the first fixing part 11 and the second fixing part 21 widens. As a result, the state in which the string 90 repeatedly bends up and down alternately is released, and it enters a released state. In the released state, the user can change the position in which the string 90 is fixed as appropriate. When the gripping part 4 closes again from the open state, the string 90 is sandwiched by the fixing structure 6 in a zigzag shape, and it enters a fixed state again.

[0064] Such a handle 1 can be used in combination with a string 90 to form a pull handle set 100.

[0065] Figure 8 illustrates one example of how to use the pull handle set 100 according to Embodiment 1.

[0066] As shown in Figure 8, the pull handle set 100 can be used to pull a carry case by tying the string 90 to a part of the carry case (for example, the handle). In other words, the user can pull the carry case by gripping and pulling the handle 4 of the handle 1, which is connected to the carry case via the string 90, rather than gripping a part of the carry case itself. Regardless of the position or condition of the carry case's handle, or vibrations of the carry case, the carry case can be easily transported using the pull handle set 100.

[0067] This example of how to use the pull handle set 100 is just one example; the string 90 can be attached to the object as needed for use.

[0068] Furthermore, for objects that already have a string 90, the handle 1 may be attached to the string 90 for use. The position of the handle 1 relative to the string 90 can be easily adjusted in the released state to an appropriate position. Also, by fixing it in place, the position of the handle 1 relative to the string 90 can be securely fixed. Since the handle 1 has a relatively simple structure, the manufacturing cost of the handle 1 can be kept low.

[0069] Furthermore, the first projection 12 and the second projection 22 are not limited to a flat plate shape, but may be formed in a curved plate shape. For example, they may be formed in a corrugated or cylindrical plate shape. In this case as well, it is sufficient that the second projection 22 fits into the valley 16 between the first projections 12.

[0070] Furthermore, the protrusions 12 and 22 may have a shape (for example, a tapered shape) such that the width dimension (thickness dimension) in the cross-section changes in the height direction. Even with such a shape, it can still be said to be plate-like.

[0071] Figure 9 is a diagram illustrating a modified example of the fixing structure 106 according to Embodiment 1. Figure 10 is a diagram illustrating the released state of the fixing structure 106 according to the same modified example.

[0072] Figures 9 and 10 show cross-sections of the fixing structure 106 portion perpendicular to the longitudinal direction of the gripping portion 4. Figure 9 shows the fixed state.

[0073] In this modified example, a first opening 31 is provided on the back of the gripping portion 4, and a second opening 32 is provided on the front. The string 90 is housed inside the gripping portion 4 between the first opening 31 and the second opening 32.

[0074] The fixing structure 106 includes two first projections 12 and one second projection 22. The second projection 22 is formed on the lower first member 110 so as to project upward at approximately the center of the front-to-back position of the gripping portion 4. The first projections 12 are provided on the upper second member 120. The first projections 12 are formed so as to project downward between the second projection 22 and the front and rear outer shell portions. In the closed state, the second projection 22 is located in the valley 16 between the two first projections 12.

[0075] Here, each projection 12, 22 has a shape in which its thickness (dimension in the front-to-back direction) changes in the vertical direction. In this embodiment, each projection 12, 22 has a shape in which the base is thicker than the tip. It can also be said that each projection 12, 22 has a tapered shape.

[0076] The string 90 is positioned in the gap 40 between the protrusions 12 and 22. Specifically, it bends upward from the first protrusion 12 towards the front of the first opening 31, bends downward at the valley 16, bends upward again at the first protrusion 12, and reaches the second opening 32. The string 90 is fixed in place by being sandwiched between the fixing structure 106 in this zigzag pattern.

[0077] As shown in Figure 10, when the second member 120 moves upward relative to the first member 110, the gap 40 widens. This releases the fixing of the string 90, resulting in a released state.

[0078] Even in this modified fixing structure 106, the effect of being able to securely fix the string 90 and easily release the fixation can be obtained.

[0079] (Embodiment 2)

[0080] Next, Embodiment 2 will be described. Embodiment 2 differs from Embodiment 1 described above in that the upper and lower members of the gripping portion are connected near one end in the longitudinal direction.

[0081] Figure 11 is a plan view of the handle 201 according to Embodiment 2 of the present invention. Figure 12 is a cross-sectional view of Figure 11 along the line FF. Figure 13 is a cross-sectional view of Figure 12 along the line GG. Figure 14 is a perspective view showing the open state of the handle 201 according to Embodiment 2.

[0082] As shown in the figure, the handle 201 has a rod-shaped gripping portion 4 as a whole. In Embodiment 2, the gripping portion 4 is composed of a first member 210 and a second member 220. The first member 210 and the second member 220 are connected near the first end 2, which is one end of the gripping portion 4 in the longitudinal direction. That is, a connecting portion 205 is provided near the first end 2. The connecting portion 205 connects the first member 210 and the second member 220 such that the second member 220 can rotate relative to the first member 210 around a rotation axis parallel to the front-rear direction.

[0083] In Embodiment 2, a locking portion 270 is provided near the second end portion 3. As shown in Figure 12, the locking portion 270 has an engaged portion 217 of the first member 210 and an engaging portion 227 of the second member 220. The engaging portion 227 is formed in a flexible shape, and the portion that can engage with the engaged portion 217 is displaceable in the left-right direction. The engaging portion 227 and the engaged portion 217 constitute a so-called snap fit, and by engaging the two, the rotation of the second member 220 relative to the first member 210 is restricted, and the closed state is maintained.

[0084] In Embodiment 2, the first opening 31 is provided at the bottom of the first member 210. The string 90 can be routed upward from the first opening 31 and pulled into the interior of the gripping portion 4.

[0085] As shown in Figure 13, the same fixing structure 6 as in Embodiment 1 can be used in Embodiment 2 as well. That is, the string 90, which is routed from the first opening 31 to the second opening 32 on either the front or rear side, is positioned in the gap 40 formed by the first projection 12 and the second projection 22 when fixed, and is sandwiched in a zigzag pattern. Therefore, the string 90 can be securely fixed.

[0086] As shown in Figure 14, in the open state, the fixing of the string 90 is released, similar to Embodiment 1. Therefore, the fixing position of the string 90 can be easily adjusted.

[0087] Thus, the same effects as in Embodiment 1 can be obtained in Embodiment 2 as described above. In Embodiment 2, a connecting portion 205 is provided near the first end portion 2, and a locking portion 270 is provided near the second end portion 3, which is relatively farther away. Therefore, even when using a locking portion 270 with a simple structure, it can withstand a relatively large force used to open the device.

[0088] (Embodiment 3)

[0089] Next, Embodiment 3 will be described. In Embodiment 3, a displaceable member is provided inside the gripping portion, and by displacing the displaceable member, the fixed state in which the string is fixed by the fixing member and the open state can be switched. To displace the displaceable member, for example, a knocking mechanism may be used.

[0090] Figure 15 is a perspective view of the handle 301 according to Embodiment 3 of the present invention.

[0091] The handle 301 has a gripping portion 304, a fixing structure 306, and a position changing portion 350.

[0092] The gripping portion 304 has, for example, a first opening 31 formed at both ends 2,3 and a second opening 32 formed at the top of the gripping portion 304. The positions of the first opening 31 and the second opening 32 are not limited to these.

[0093] The fixing structure 306 is housed inside the gripping portion 304. The fixing structure 306 has a first fixing portion 311 and a second fixing portion 321. The first fixing portion 311 and the second fixing portion 321 are aligned in the longitudinal direction, and the string 90 is passed through the gap 40 between them.

[0094] In this embodiment, the fixing structure 306 is configured such that the displacement portion is displaceable in a direction toward or toward the displaced portion, and the displacement portion is displaceable at least relative to the gripping portion 304. In the example shown in the figure, the second fixing portion 321 is the displacement portion, and the first fixing portion 311 is the displaced portion. That is, the first fixing portion 311 is fixed to the gripping portion 304. Furthermore, the second fixing portion 321 is displaceable in the longitudinal direction relative to the gripping portion 304, and is displaceable in a direction toward or toward the first fixing portion 311.

[0095] The position change section 350 includes a knocking mechanism 351 and an operating section 353. The operating section 353 is positioned to be exposed to the outside, for example, by protruding longitudinally from the first end 2. The operating section 353 is positioned so that it can be pushed into the gripping section 304 by the user. The knocking mechanism 351 is positioned inside the gripping section 304. The knocking mechanism 351 is positioned between the operating section 353 and the second fixing section 321.

[0096] Thus, in this embodiment, the position-changing section 350 has a knock mechanism 351 that can be pushed in by the user via an operating section 353 that is exposed to the outside from a part of the gripping section 304. The knock mechanism 351 is configured to change the position of the displaced section relative to the displaced section, that is, the position of the second fixing section 321 relative to the first fixing section 311.

[0097] In this embodiment, a known mechanism can be used as the knock mechanism 351. For example, the knock mechanism 351 can be a mechanism similar in principle to the mechanism used to extend the pen tip in a retractable ballpoint pen or the like. That is, the knock mechanism 351 has a cam provided in the mechanism body, a rotor that engages with the cam, and a knock part that rotates the cam. The cam has grooves or protrusions on its surface so that the extended and retracted state of the tip shaft switches depending on the engagement position of the rotor. Each time the operating part 353 is operated, the cam is rotated by the knock part, and the engagement position of the rotor is switched, so that the state in which the tip shaft protrudes or retracts in the longitudinal direction is switched. The second fixed part 321 is biased in the longitudinal direction by this tip shaft, and the position of the second fixed part 321 relative to the first fixed part 311 changes depending on the state of the knock mechanism 351.

[0098] Figure 16 shows the released state of the fixing structure 306 according to Embodiment 3. Figure 17 shows the fixed state of the fixing structure 306 according to Embodiment 3.

[0099] In Figures 16 and 17, the structure is shown in a slightly simplified manner for illustrative purposes.

[0100] As shown in Figure 16, in this embodiment, the string 90 is routed from the first opening 31 through the wire passage 33 to the location of the gap 40. Then, it is routed through the gap 40 to exit the gripping portion 304 through the second opening 32.

[0101] In the fixing structure 306, the first fixing portion 311 and the second fixing portion 321 have projections 12 and 22 that protrude toward each other, as described above. In the example shown in the figure, the first fixing portion 311 has three first projections 12 arranged in the vertical direction. The second fixing portion 321 has two second projections 22 that are formed to fit into the grooves 12 between the first projections 12.

[0102] When the operating part 353 is operated in the released state, the second fixing part 321 is displaced toward the first fixing part 311 and becomes fixed. That is, as shown in Figure 17, the gap 40 formed by the first projection 12 and the second projection 22 becomes such that the string 90 is sandwiched in a zigzag pattern. In this fixed state, the string 90 is securely fixed.

[0103] Furthermore, if the operating part 353 is operated again while the unit is fixed, the knocking mechanism 351 displaces the second fixing part 321 away from the first fixing part 311, resulting in the release state.

[0104] Thus, in this embodiment 3 as well, the string 90 can be securely fixed and released. In this embodiment, since the position changing section 350 is configured using a knocking mechanism 351, it is possible to easily switch between the fixed state and the released state.

[0105] In Embodiment 3, the position-changing section 350 may have a different structure from the knock mechanism 351. For example, a displacement member may be provided that is slidable in the longitudinal direction relative to the gripping section 304 and can maintain its position by engaging with the housing of the gripping section 304, and the position of the displacement section relative to the displaced section may be changed according to the position of the displacement member. Alternatively, for example, a mechanism such as a linear screw may be used to change the position of the displacement section relative to the displaced section.

[0106] Furthermore, in the above example, the second fixing part 321 is the displaceable part and the first fixing part 311 is the displaced part, but this is not limited to this. The first fixing part 311 may be the displaceable part and the second fixing part 321 may be the displaced part. Also, both the first fixing part 311 and the second fixing part 321 may be displaceable relative to the gripping part 304 and displaceable relative to each other.
