Pull line storage device

Technical Field

The present invention relates to a traction line storage device capable of winding and drawing out a traction line or other pull belt for pets.

Background Art

Conventionally, there are known devices for storing traction lines used for walking pets such as dogs, in which a biasing member such as a coil spring is used to pull out the traction line against an applied force, and the accumulated applied force is used to wind up the traction line. These traction line storage devices are configured such that the traction line is pulled out by an external force associated with the pet's movements, and the accumulated applied force is used to wind up the traction line.

The pull line storage device disclosed in Patent Document 1 below, proposed by the applicant of the present invention, provides a technology that allows the pull line to be drawn out and wound up within the pull line's withdrawal limit, and that can be stopped by a user's operation. The pull line storage device disclosed in Patent Document 1 employs a technology that uses a winding reel to allow the pull line to be drawn out and wound up, and is provided with a locking device to restrict the withdrawal of the pull line in the event that the pull line withdrawal is to be stopped urgently.

However, various circumstances exist for pets using leashes. The distance the leashes can be extended defines the range within which the pet can move, and it is desirable to be able to expand or reduce the range of movement depending on the environment. For example, when using a pet in a larger location like a park, a slightly larger range is acceptable, but when walking on a regular road, it is desirable to limit the pet's range of movement.

In the pulling wire storage device of Patent Document 1, although the pulling wire can be pulled out and wound up within the maximum pulling distance of the pulling wire, the pulling out and winding range cannot be switched at a distance intermediate the maximum pulling distance of the pulling wire.

Summary of the Invention

Therefore, an object of the present invention is to provide a pulling wire storage device that allows a user to select a pulling wire drawing range in which the pulling wire can be drawn out and wound up.

The traction line storage device of the present invention provided in order to solve the above-mentioned problems is characterized in that it is a traction line storage device for storing traction lines for pets and other animals, and is provided with: a reel, which can extract the traction line by rotating in the forward direction and reel the traction line by rotating in the reverse direction; a force-applying component, which receives the external force accompanying the extraction of the traction line and accumulates the force, and applies force to the rotation of the reel in the reverse direction as the external force is released; a rotating component having an engaged portion on the circumference, which rotates in conjunction with the reel; and a engaging component having a locking portion that engages with the engaged portion. The engaging portion is an engageable engaging portion and is arranged at a predetermined circumferential position relative to the rotating component; the switching component can switch between an engageable state in which the engaged portion and the engaging portion are engageable and an unengageable state in which the engaged portion and the engaging portion cannot be engaged. By setting the engageable state, the rotation range of the rotating component is limited to a range with the engaging position where the engaging portion and the engaged portion are engaged as the end point, and the extractable range of the traction line can be limited based on the rotation range (that is, multiple lengths can be selected for the length of the extracted traction line).

In the pull wire storage device of the present invention, the engaged portion is provided on the rotating member that rotates in conjunction with the reel, and the engaging member having an engaging portion engageable with the engaged portion is arranged at a predetermined circumferential position relative to the rotating member.

In addition, in the pull wire storage device of the present invention, the switching member can be used to switch between an engageable state in which the engaged portion and the engaging portion can engage and an unengageable state in which the engaged portion cannot engage. By setting the engageable state, the pull-out range of the pull wire can be limited.

Therefore, according to the present invention, it is possible to provide a pulling wire storage device capable of adjusting (selecting) a pulling wire drawing range by switching between an engageable state and an unengageable state using a switching member.

The pulling wire storage device of the present invention preferably includes an intermediate rotating member that rotates in conjunction with the rotation of the reel and transmits the rotation of the reel to the rotating member.

In addition, in the pulling line storage device of the present invention, the rotation of the reel is transmitted by an intermediate rotating member between the rotation of the reel and the rotation of the rotating member. By providing the intermediate rotating member, the reel speed during the period when the rotating member rotates and reaches the engaging position can be appropriately set.

Therefore, according to the present invention, it is possible to suppress the restriction of the diameter of the reel or the rotating member, thereby achieving miniaturization of the reel and the rotating member or miniaturization of the entire pulling wire storage device.

In addition, in the traction line storage device of the present invention, preferably, the locking component has a locking claw that works integrally with the locking portion, and a plurality of locking teeth that can be locked by the locking claw are arranged circumferentially on the side of the reel. When the locking portion and the locked portion are engaged, the locking claw and the locking teeth engage to limit the rotation of the reel.

In the pulling line storage device of the present invention, when the engaging portion and the engaged portion are in an engaged state, the locking teeth and the locking claws located on the reel side are also in an engaged state. In this way, the locking teeth and the locking claws can be engaged, and the rotation of the reel can be further reliably suppressed.

In addition, according to the above structure, the rotation of the reel can be directly restricted, and even if a strong external force is applied to the pulling line in the engaged state, the rotation of the reel in the positive direction can be further and more reliably restricted.

The pulling wire storage device of the present invention may include a locking member that can be locked with respect to the locking teeth or the rotating member.

By providing a component other than the engaging component that contacts the locking teeth or the rotating component to limit the rotation of the reel, as in the present invention, a braking mechanism and a locking function can be added to the pull line storage device. That is, regardless of the distance the pull line is pulled out, functions such as an emergency stop for pulling out the pull line or locking the pull line withdrawal distance can be provided to meet the needs of the user.

According to the present invention, it is possible to provide a pulling wire storage device that allows a user to select a pulling wire drawing range in which the pulling wire can be drawn out and wound up.

DETAILED DESCRIPTION

Hereinafter, with reference to the accompanying drawings, a detailed description will be given of a pull line storage device 10 according to an embodiment of the present invention. The pull line storage device 10 has an appearance as shown in FIG1 . In addition, as shown in the structural schematic diagram of the pull line storage device 10 shown in FIG1 or FIG2 , the pull line storage device 10 includes a reel 50, an intermediate switch 70, a rotating member 130, an intermediate gear 120 (intermediate rotating member), a switching member 140, and a brake portion 150. The pull line storage device 10 winds the pull line 2 on the winding portion 52 of the reel 50 described below, and allows the pull line 2 to be taken in and out via the pull line extraction portion 26 provided on the housing 20.

The pulling line storage device 10 applies a tensile external force in the direction of drawing out the pulling line 2, thereby rotating the reel 50 in the direction of drawing out the pulling line 2 (positive direction), thereby drawing out the pulling line 2. In addition, as the pulling line 2 is drawn out, a force is accumulated on the coil spring (not shown) described below, and the accumulated force is used to rotate the reel 50 in the direction of winding the pulling line 2 (negative direction), thereby winding the pulling line 2.

Thus, the pull line storage device 10 has a pull line extractable range (free range) for extracting the pull line 2 and winding the pull line 2 by the applied force. As described in detail later, the pull line storage device 10 has technical features such as being able to set the pull line extractable range (free range) to a maximum range (maximum free range) that matches the full length of the pull line 2, and also being able to set the free range to an intermediate range (intermediate free range) that is shorter than the maximum free range.

Next, the structure of each component of the pull line storage device 10 will be described in detail. As shown in Figures 2 and 4, the housing 20 is provided to house the various mechanisms of the pull line storage device 10. The housing 20 is provided with a reel storage portion 22, a handle portion 24, and a pull line extraction portion 26.

The reel storage portion 22 is provided for storing the reel 50 and the gear mechanism 100. Furthermore, the handle portion 24 functions as a grip for the user P of the pull line storage device 10 to grasp. Furthermore, the pull line extraction portion 26 allows the pull line 2 to be inserted into and removed from the outside of the housing 20.

The housing 20 includes a first housing structure 20a shown in Fig. 4(a) and a second housing structure 20b shown in Fig. 4(b). The housing 20 includes a first housing structure 20a and a second housing structure 20b. The first housing structure 20a and the second housing structure 20b are combined to form a space constituting the reel storage portion 22 inside the housing 20.

Furthermore, a switching member storage area 32 is provided in the portion of the first housing structure 20a that is located outside the reel storage section 22. This area is recessed in a substantially circular manner from the outside of the housing toward the inside. The switching member storage area 32 includes a partition wall 34 and a peripheral surface 36 that define the area from the reel storage section 22. An intermediate gear protrusion hole 40 is provided in the partition wall 34, extending through the inside and outside of the housing 20.

Furthermore, an engagement portion protruding hole 38 is provided on the peripheral surface 36. Furthermore, a free range indicator 28 is provided at a position adjacent to the engagement portion protruding hole 38 and outside the switching member storage area 32.

As shown in FIG4(b), a reel support shaft 30 is provided on the bottom surface side of the reel storage portion 22. The reel support shaft 30 supports the reel 50 in the housing 20 so as to be rotatable.

5 , the reel 50 includes a winding portion 52 and flanges 54a and 54b. The reel 50 is housed in the reel housing 22 of the housing 20 with the flange 54a facing the first housing structure 20a and the flange 50b facing the second housing structure 20b.

The winding portion 52 is a cylindrical member capable of winding the pulling wire 2 and provided with a shaft through-hole 66 for insertion into the reel support shaft 30. The winding portion 52 has a built-in coil spring (biasing means) (not shown).

Therefore, when an external force is applied to the outside of the housing 20 to pull out the traction line 2, a force is accumulated in the coil spring (not shown). In addition, when the external force in the direction of pulling out the traction line 2 decreases, the force accumulated in the coil spring causes the reel 50 to rotate in the opposite direction of the pulling line 2, thereby winding the traction line 2.

As shown in Figures 5(a) and 5(c), the flanges 54a and 54b are provided with a plurality (eight in this embodiment) of claw-shaped locking teeth 56a and 56b extending radially outward from the rotation center of the reel 50. The locking teeth 56a and 56b have sliding side surfaces 60a and 60b that are the front side surfaces in the positive rotation direction of the reel 50, and locking side surfaces 58a and 58b that are the rear side surfaces in the positive rotation direction.

The sliding side surfaces 60a and 60b are curved in a plan view. Specifically, the sliding side surfaces 60a and 60b are curved so as to be directed radially outward from the rotation center of the reel 50 toward the rear side in the normal rotation direction of the reel 50. On the other hand, the locking side surfaces 58a and 58b extend linearly from the rotation center of the reel 50 toward the radial outward.

As shown in FIG5(a), a driving gear receiving portion 62 is formed on the flange portion 54a. The driving gear receiving portion 62 receives a driving gear 110, which will be described later. The driving gear 110 is fixed to the driving gear receiving portion 62. Various methods are contemplated for fixing the driving gear 110, such as a structure in which convex portions and concave portions are provided on the outer periphery of the driving gear 110 and the inner periphery of the driving gear receiving portion 62 and are engaged with each other.

The gear mechanism 100 is configured to rotate in accordance with the rotation of the reel 50 and to be capable of switching freely. The gear mechanism 100 comprises a driving gear 110 fixed to the reel 50, an intermediate gear 120 (intermediate rotating member) that transmits the rotation of the driving gear 110, and a rotating member 130 (rotating member) that rotates in response to the rotation of the intermediate gear 120.

As shown in Figure 7, the driving gear 110 and the intermediate gear 120 are housed inside the reel storage section 22. Meanwhile, the rotating member 130 is disposed within the switching member storage area 32 formed outside the reel storage section 22, via a partition wall 34. The intermediate gear 120 protrudes from the inside of the reel storage section 22 into the switching member storage area 32 through an intermediate gear protrusion hole 40, a portion of which is provided in the partition wall 34, and engages with the rotating member 130.

Next, details of the gears constituting the gear mechanism 100 will be described with reference to the drawings. FIG6 shows a plan view and a front view of the driving gear 110, the intermediate gear 120, and the rotating member 130 constituting the gear mechanism 100.

6( c ), the driving gear 110 includes a fixing portion 114 for fixing to the reel 50 and an intermediate gear engaging portion 112. The driving gear 110 is fixed by receiving the fixing portion 114 in the driving gear receiving portion 62 of the reel 50 and rotates as the reel 50 rotates.

As shown in FIG6(b), the intermediate gear 120 includes a driving gear engaging portion 122, a switch gear engaging portion 124, and a partition wall inserting portion 126. The driving gear engaging portion 122 engages with the intermediate gear engaging portion 112 provided on the driving gear 110. Therefore, the intermediate gear 120 rotates by transmitting the rotation of the driving gear 110.

7 , the intermediate gear 120 has the partition wall fitting portion 126 fitted into the intermediate gear protruding hole 40 provided in the partition wall 34 , and the switch gear engaging portion 124 protrudes toward the switching member housing region 32 .

The rotating member 130 is provided to rotate in conjunction with the rotation of the reel 50 and to enable free range switching by being engaged with the engaging portion 74 described in detail later. The rotating member 130 is a disc-shaped member having an outer diameter substantially the same as the inner diameter of the switching member storage area 32 provided in the housing 20. The rotating member 130 is rotatably embedded in the switching member storage area 32 with its surface 130a facing the outside of the pull line storage device 10 and its back surface 130b facing the partition wall 34.

As shown in FIG6(a), a gear-shaped intermediate gear engaging portion 138 is provided on the back surface 130b of the rotating member 130. The switch gear engaging portion 124 of the intermediate gear 120 engages with the intermediate gear engaging portion 138. Therefore, the rotating member 130 rotates within the switching member storage area 32 by transmitting rotational force via the intermediate gear 120 as the reel 50 rotates.

An engaged portion 132 is provided on the outer periphery of the rotating member 130. The engaged portion 132 is a concave member that is recessed from the radially outer side to the inner side of the rotating member 130. The engaged portion 132 is engaged by an engaging portion 74 provided on the intermediate switch 70 described below.

As shown in FIG2 , the intermediate switch 70 (engaging member) is provided at a predetermined circumferential position adjacent to the radially outer side of the rotating member 130. As shown in FIG8 , the intermediate switch 70 is integrally formed with a support portion 72, an engaging portion 74, locking claws 76a and 76b, and a locking claw connecting portion 78.

The intermediate switch 70 has a latching claw connecting portion 78 extending in a direction intersecting the columnar support portion 72, and latching claws 76a and 76b at both ends of the latching claw connecting portion 78. A substantially cylindrical engaging portion 74 is provided upright on the latching claw 76a.

As shown in FIG2 and other figures, the intermediate switch 70 is housed inside the housing 20, extending from the handle 24 to the reel storage section 22. Furthermore, the intermediate switch 70 is biased in a direction from the handle 24 side toward the reel 50 side by a coil spring 80 attached to the end of the support section 72 opposite the end where the locking claw connection section 78 is provided. Specifically, the engaging section 74 is biased so as to protrude from the engaging section protrusion hole 38 of the housing 20 into the switching member storage area 32.

Therefore, when the rotating member 130 embedded in the switching member storage area 32 is rotated and the engaged portion 132 reaches a position adjacent to the engaging portion protruding hole 38, the engaging portion 74 is protruded from the engaging portion protruding hole 38 and enters and engages the engaged portion 132. In addition, the intermediate switch 70 is slid toward the reel 50 side.

Furthermore, the intermediate switch 70 is mounted relative to the housing 20 so that the locking claws 76a and 76b face the reel 50. As described above, when the intermediate switch 70 slides toward the reel 50, the locking claws 76a and 76b also move toward the reel 50. Consequently, the locking claws 76a and 76b move to a position where they can engage with the locking teeth 56a and 56b. When the locking claws 76a and 76b engage with the locking teeth 56a and 56b, the rotation of the reel 50 is restricted.

The switching member 140 is provided to switch between a state in which the engaging portion 74 is prohibited from entering the engaged portion 132 (disengageable state) and a state in which the engaging portion 74 is permitted to enter the engaged portion 132 (engageable state). As shown in FIG9 , the switching member 140 is generally circular in shape and has an outer diameter that is approximately the same as that of the rotating member 130.

The switching member 140 includes a recessed portion 142, a guide portion 144, and a mounting portion 146. The recessed portion 142 is provided on the outer edge of the switching member 140 and is formed into a concave shape from the outer circumference toward the center. The guide portion 144 is provided to facilitate the user P of the pull-wire storage device 10 in rotating the switching member 140 and is located at a position corresponding to the recessed portion 142.

The switching member 140 is mounted on the rotating member 130 so as to cover the outside of the pull wire storage device 10 by fitting the mounting portion 146 into the switching member fitting portion 42 of the partition wall 34. The switching member 140 is rotated using the guide portion 144, thereby rotating while the side surface abuts against the peripheral surface 36 of the switching member storage area 32.

As described above, when the engaged portion 132 is aligned with a position adjacent to the engaging portion protruding hole 38, an area into which the engaging portion 74 can enter is formed. Therefore, when the engaging portion protruding hole 38 reaches a position connected to the recessed portion 142 with the guide portion 144 aligned with the portion indicated as "middle" in the free range indicator 28 (middle free range indicator area 46), the engaging portion 74 is able to enter the area into which the engaging portion 74 can enter.

On the other hand, when the guide portion 144 is aligned with the portion displayed as "maximum" (maximum free area 44) located at a position deviating from the middle free range display area 46, the outer edge of the switching component 140 is used to restrict the engagement portion 74 from entering the enterable area.

Next, the arrangement of the gear mechanism 100 and the switching member 140 will be described with reference to the drawings. Fig. 7 is an exploded perspective view of the gear mechanism 100 and the switching member 140. As described above, the rotating member 130 rotates in conjunction with the rotation of the reel 50.

When the pulling line 2 is pulled out and the reel 50 rotates in the forward direction (counterclockwise in FIG. 7 ), the intermediate gear 120, to which the rotation is transmitted from the driving gear 110, rotates in the opposite direction to the driving gear 110 (clockwise in FIG. 7 ). In addition, the rotating member 130, which transmits the rotational force from the intermediate gear 120 to the intermediate gear meshing portion 138, rotates in the same direction as the intermediate gear 120 (clockwise in FIG. 7 ).

Thus, the rotating member 130 transmits the rotation of the reel 50 and rotates in the direction of rotation of the reel 50. Meanwhile, the switching member 140 does not rotate in conjunction with the rotation of the rotating member 130, but rotates only when the user P operates the guide portion 144.

The brake unit 150 is provided to prevent the reel 50 from rotating in either the forward or reverse direction and to maintain the pull line 2 within a predetermined distance. As shown in Figure 10, the brake unit 150 includes a locking member 152, a compression spring 154, and an operating unit 156. The locking member 152 is housed within the handle 24 and is biased away from the reel 50 by the compression spring 154. The operating unit 156 can swing about a swing fulcrum 158 fixed to the housing 20.

As shown in Figures 1 and 2, a portion of the operating portion 156 protrudes outward from the inside of the handle portion 24. When the portion of the operating portion 156 that protrudes from the handle portion 24 is grasped, the operating portion 156 swings about the swing fulcrum 158, and the locking member 152 slides toward the reel 50 against the biasing force of the compression spring 154. As a result, the locking member 152 engages with the locking teeth 56a and 56b of the reel 50, inhibiting the reel 50 from rotating in the forward and reverse directions, that is, locking the reel 50.

Next, regarding the free range switching of the pulling wire storage device 10, the case where the free range is set as the extraction limit of the pulling wire 2 (maximum free range) and the case where the extraction of the pulling wire 2 is restricted at an intermediate distance (intermediate free range) will be described with reference to the drawings.

Selecting the Maximum Freedom

FIG11 shows the positional relationship between the switching member 140, the rotating member 130, and the reel 50 when the maximum free range is selected. FIG11 omits illustration of the driving gear 110, the intermediate gear 120, the partition wall 34, and the like. FIG11( a ) is a perspective view of the switching member 140, the rotating member 130, the reel 50, and the intermediate switch 70 when the maximum free range is selected.

Figures 11(a) and 11(b) illustrate the initial state (before the pulling line 2 is withdrawn). In this initial state, the engaged portion 132 of the rotating member 130 is located adjacent to the starting position S shown in the same figure. When the pulling line 2 is withdrawn, the rotating member 130 rotates in conjunction with the rotation of the reel 50. As a result, the rotating member 130 rotates clockwise from the starting position S, and soon the engaged portion 132 reaches the engaging portion protruding hole 38.

Here, as shown in Figure 11(b), when the guide portion 144 provided on the switching component 140 is aligned with the position displayed as "maximum" on the free range display portion 28 provided on the shell 20, as shown in Figure 11(c), the locking portion 74 is restricted by the outer edge of the switching component 140 and becomes unable to protrude from the protruding hole 38 of the locking portion.

Therefore, even when the rotating member 130 reaches a position where the engaged portion 132 is adjacent to the engaging portion protruding hole 38, the engaging portion 74 does not engage with the engaged portion 132. Furthermore, the locking claws 76a and 76b, which move integrally with the engaging portion 74, do not move toward the reel 50, and the locking claws 76a and 76b do not engage with the locking teeth 56a and 56b. Therefore, when the guide portion 144 is aligned with the "maximum" position displayed on the free range indicator 28, the pull-out limit of the pull line 2 is set to a length substantially equivalent to the full length of the pull line 2, and the pull line 2 can be pulled out and wound within this range.

Selecting the middle free range

Next, referring to the drawings, a description will be given of a case where a predetermined intermediate distance is set as the free range (intermediate free range) in the withdrawal limit of the pulling wire 2. FIG12 shows the positional relationship between the switching member 140, the rotating member 130, and the reel 50 when the intermediate distance is set as the free range (intermediate free range).

11, the driving gear 110, the intermediate gear 120, the partition wall 34, etc. are omitted in FIG12. FIG12(a) is a perspective view of the switching member 140, the rotating member 130, the reel 50, and the intermediate switch 70 when the intermediate free range is selected.

As shown in Figure 12(b), when the guide portion 144 of the switching component 140 is aligned with the portion displayed as "middle" on the free range display portion 28, the recess 142 is positioned adjacent to the protruding hole 38 of the locking portion and the locking portion 74 can enter the locked portion 132 of the switch gear 130.

When the pulling line 2 is pulled out in this state, the rotating member 130 rotates in conjunction with the rotation of the reel 50. Soon, when the engaged portion 132 reaches a position corresponding to the engaging portion protruding hole 38, the engaging portion 74 of the intermediate switch 70 enters the recess 142 and the engaging portion protruding hole 38 and engages. Furthermore, the locking claws 76a and 76b, like the engaging portion 74, move toward the reel 50 and engage with the locking teeth 56a and 56b.

Here, as shown in Figure 13, when the engaged portion 132 reaches the position engaged with the engaging portion 74, the locking claws 76a, 76b come into contact with the locking teeth 56a, 56b. In this state, even if an external force is applied in the direction of withdrawing the pulling line 2, the locking claw 76a also contacts the locking tooth 56a, so the reel 50 cannot continue to rotate in the positive direction.

On the other hand, as shown in Figure 13(b), when the reel 50 rotates in the reverse direction, the locking claw 76a contacts the side surface of the smoothly curved locking tooth 56a. In this case, the force of rewinding the reel 50 is transmitted to the driving gear 110, the intermediate gear 120, and the rotating member 130, pushing the intermediate switch 70 back at the R-shaped portion formed in the engaged portion 132. This allows the reel 50 to rotate without being restricted, and the traction line 2 can be wound.

Therefore, when the guide portion 144 is aligned with the portion indicated as "middle", the pull-out limit of the pull-wire 2 is limited to a length less than substantially the entire length of the pull-wire 2, and the pull-out and winding of the pull-wire 2 can be performed within this range.

Figure 14 illustrates the use of the traction line storage device 10 for walking a pet such as a dog. Figure 14(a) shows the maximum free range selected, while Figure 14(b) shows the intermediate free range selected. As shown in Figure 14(a), when the maximum free range is selected, the pet can move within the pull-out range L of the traction line 2, and the traction line 2 can be pulled out and reeled in within the range L.

On the other hand, as shown in FIG14( b ), when the intermediate free range is selected, the pet's movement can be restricted within the pull-out range M of the traction line 2. In this case, either the pull-out or the reel-in of the traction line 2 can be performed within the range M. Furthermore, the brake can be activated within any of these ranges.

As described above, in this embodiment, the reel 50 is provided with the retaining teeth 56a, 56b, and the rotation of the reel 50 is restricted by the engagement of the retaining claws 76a, 76b with the retaining teeth 56a, 56b. However, the pull line storage device of the present invention is not limited to this. In other words, the reel 50 may not be provided with the retaining teeth 56a, 56b, and the rotation of the rotating member 130 may be prevented and the rotation of the reel 50 may be restricted by the engagement of the engaging portion 74 with the engaged portion 132.

In addition, in this embodiment, an example is shown in which the switching member 140 is provided on one side surface of the housing 20 , but the switching member 140 may also be provided on the bottom surface side of the housing 20 , so that three or more free ranges can be selected.

In addition, in this embodiment, the example in which the pull line storage device 10 is provided with the brake portion 150 is shown, but a function of locking the position of the locking member 152 may be added. If such a locking function is added, when the user P uses the pull line storage device 10 for a walk with a pet, the length of the pull line 2 can be maintained according to the user P's preference.

While representative embodiments of the pull line storage device of the present invention have been described above, the present invention is not limited thereto. That is, various design modifications are possible within the scope of the technical concept of the present invention as described in the claims, and all of these modifications are encompassed by the present invention.
