Description

  The present invention relates to a cage with casters, and more particularly, to a cage that can be moved lightly by limiting the moving range or by pulling.

  Casters with casters that can be extended and retracted up and down have already been developed and used a lot. Many types of kites with this structure are of a size that can be brought into an aircraft, or that are slightly larger. For example, US Pat. No. 4,995,487 (Patent Document 1), Japanese Patent Publication No. 4-76686 (Patent Document 2), Japanese Utility Model Laid-Open No. 57-179824 (Patent Document 3), and Japanese Utility Model This is described in Japanese Patent Laid-Open No. 63-131634 (Patent Document 4).

  The scissors described in these publications are provided with two casters 71 on one side of the bottom as shown in FIG. A short leg 75 is fixed to the opposite side of the caster 71. When the heel is set up vertically, the casters 71 and the legs 75 come into contact with the floor. In this state, since the leg 75 which does not rotate contacts, the heel will stand vertically without moving. Furthermore, a handle 72 is provided so that it can be pulled out to the upper surface in order to pull and move the bag. The handle 72 is provided on the same side as the caster 71 because the handle 72 is pulled and moved while the heel is inclined.

  As shown in FIG. 1, the scissors having this structure can be moved by tilting the scissors and pulling the handle 72. When the heel tilts, the casters 71 come into contact with the floor and the legs 75 move away from the floor. When the handle 72 is pulled in this state, the caster 71 rotates and can be moved easily. However, there are cases in which the casters 71 cannot be used when the kite moved in this way is narrow or crowded as in an aircraft. This is because, when the vehicle is run on the casters 71, the lateral width of the kite increases, and it cannot move freely in a narrow passage between seats in the cabin or in a crowded place. When the caster 71 cannot be used, it is necessary to lift and move the bag by hand. When it is lifted and moved by hand, it can be moved in the direction indicated by arrow A in FIG. 1 so that the lateral width does not increase.

  Casters with casters are a convenient structure for moving heavy kites lightly and easily. This is because even if the bag is heavy, it can be moved easily on casters. The present inventor has developed a bag having a structure shown in FIG. 2 in order to eliminate such a drawback (see Patent Document 5). The bag in this figure has a caster 81 attached to the bottom surface of the case body 83. The casters 81 are provided at the four corners of the bottom surface so that the case body 83 can stand upright in a vertical posture. The grip portion 84 of the handle 82 is located above the case body 83 and at the center of the left and right. The scissors having this structure are not moved by tilting the scissors like the scissors shown in FIG. 2. Move the heel in a vertical position in the direction indicated by the arrow in FIG. When moved in the direction indicated by the arrow, the width can be reduced. For this reason, it has the feature that it can move conveniently in the cabin or in crowded places. Furthermore, since the four casters 81 are free casters that can move in any direction, the heel can move in any direction in a vertical posture. In the vertical posture, the weight of the heel does not act on the handle 82. For this reason, even if the bag is extremely heavy, it can be moved easily by simply pressing it.

The bag with this structure can be moved lightly and easily with four casters by pressing the handle of the handle. However, since the bag of this structure is self-supporting by the casters at the four corners, there is a drawback that it moves when the train is accelerated or decelerated in a state where it is not moved, for example, on a train. This drawback can be solved by connecting a string to the heel body as described in Patent Document 6, for example. This heel can limit the movement range by grasping the end of the string connected to the heel body. Further, the hook connecting the strings can be moved by pulling the strings. However, when the extension handle is connected to the bag main body, and the hook is moved, the extension rod is stopped in the extended state, and the hook that is moved by grasping the grip is shown in FIG. Since the height of the hand is lower than the position of the hand, it is considerably strong when pulling the string 96 connected to the heel body 93 to limit the movement of the heel body 93 or when pulling the heel body 93 to move. It is necessary to pull with force. This is because, as shown in FIG. 3, the direction in which the string 96 is pulled does not match the direction in which the heel body 93 is moved. For example, as shown in the figure, when the string 96 is pulled in the direction of 45 degrees, the horizontal component that is the moving direction of the heel body 93 is ^2-1/2 times the tensile force of the string 96. , About 70%. This is because the horizontal component force that moves the heel is the product of the tensile force of the string and cos θ, and decreases as the inclination angle θ of the tensile force with respect to the horizontal direction increases. Since a cage with a caster is characterized by being able to move a heavy object lightly, it often becomes a heavy cage, so that the force to move by pulling it becomes large, or the tensile force to limit the movement range is When it becomes strong, there is a drawback that it cannot be used easily. In particular, in a state where the range of movement is limited, it is important to be able to stop the movement with the weakest possible force because it moves unexpectedly by acceleration or deceleration of the train rather than pulling it yourself. is there.

US Pat. No. 4,995,487 Japanese Examined Patent Publication No. 4-76686 Japanese Utility Model Publication No.57-179824 Japanese Utility Model Sho 63-131634 Japanese Patent Laid-Open No. 10-137022 JP-A-6-266324

  The first object of the present invention is to solve the above-mentioned drawbacks, that is, by moving a heavy kite with a light force through a string and restricting the kite from moving unexpectedly with a light tensile force. The purpose is to provide a bag with casters that can be used easily.

  In addition, casters are provided at the four corners of the kite body to stand on their own, and the kite that is moved by grasping the upper end grip while pulling up the telescopic handle in this posture is moved in a vertical posture when it is uneven and has high road resistance. There are drawbacks that make it difficult to collapse. This disadvantage can be solved by increasing the outer diameter of the caster. However, if the casters are made larger, the entire bag becomes larger. Therefore, it is necessary to reduce the size of the bag body if the bag is restricted by the overall dimensions. For this reason, there is an adverse effect that the storage capacity of the bag main body is reduced. Since it is extremely important to increase the storage capacity of the bag, the outer diameter of the caster is limited in applications where the overall dimensions are limited. For this reason, when moving a road surface with large unevenness, the caster is caught by the road surface unevenness and cannot move smoothly. The heel that is moved by pushing the grip at the upper end while the telescopic handle is pulled up will fall forward if the road surface resistance of the caster is large, so it cannot move smoothly and easily.

  A second object of the present invention is to provide a caster-equipped scissor that can move easily and smoothly in a posture in which a road surface having a large road resistance is not stably tilted without enlarging the caster.

  According to a seventh aspect of the present invention, a bag with a caster includes a bag main body 3 having a caster 1 that can run in free directions at four corners of the bottom surface, an extendable handle 2 connected to the bag main body 3, and a bag main body. 3 and a subgrip 6 made of a string material of a predetermined length connected to 3. The extendable handle 2 extends upward from the heel body 3 and is self-supporting, and is extendable in the vertical direction and is provided with a grip 4 at the upper end, and a stopper 15 for stopping the extendable rod 5 at the extended position; Is provided. A heel with a caster restricts the range of movement of the heel body 3 by holding the heel body 3 in a vertical posture with the grip 4 of the extendable handle 2 and holding the subgrip 6 made of a string material connected to the heel body 3. Alternatively, the bag body 3 is pulled to move.

  According to the eighth aspect of the present invention, the bag with a caster is the bag with a caster according to the seventh aspect, wherein the total length of the string material of the sub grip 6 is 10 cm to 90 cm.

  According to a tenth aspect of the present invention, the bag with a caster is the bag with a caster according to the seventh aspect, and the telescopic rod 5 is fixed to the side surface of the main body 3. The telescopic rod 5 is inclined or curved in a direction in which the grip 4 at the upper end is positioned at the center of the heel body 3.

  The caster-equipped scissors according to claim 11 of the present invention is a caster-equipped scissors according to claim 7, comprising a base frame 7 on which the scissors main body 3 is placed and connected, and casters at four corners of the base frame 7. 1 is connected, and the telescopic rod 5 is connected to the side. The telescopic rod 5 is inclined or curved in a direction in which the grip 4 at the upper end is positioned at the center of the heel body 3.

  The caster-equipped scissors according to claim 12 of the present invention is a caster-equipped scissors according to claim 7, and the telescopic handle 2 is provided with a stopper 15 that stops at an intermediate pull-out position.

  The bag with a caster according to the present invention has a feature that a heavy bag can be pulled and moved through a string with a light force, and the bag can be used easily by restricting a bag from moving unexpectedly with a light pull. That is, the hook of the present invention connects the subgrip of the string to the extendable handle, grasps the subgrip with the hand, and pulls the hook main body to move, or restricts the movement range, so that the extendable handle can be expanded and contracted. This is because the pulling direction of the string as the sub-grip can be adjusted to the horizontal direction as the moving direction of the bag main body. The sub-grip that pulls the heel body in the horizontal direction, which is the direction of movement, can be used effectively to move the heel body, and even the heavy heel body can be moved by pulling lightly and smoothly. There is a feature that can lightly prevent the movement. In particular, the bag of the present invention is connected to an extendable handle that can extend and retract the subgrip of the string, so that the extension rod can be extended and adjusted to the height at which the subgrip is pulled. For this reason, even if the height at which the sub-grip pulls the cocoon body changes, the telescopic rod can be expanded and contracted to adjust the tensile force in the horizontal direction, which is the moving direction of the cocoon body. For example, when used in a state where a tall person is standing, the position of the hand that pulls the sub-grip becomes high, so that the telescopic rod can be extended to raise the position of the sub-grip and be pulled easily. In addition, when a person with a short height uses it, the telescopic rod can be adjusted so that the position of the sub grip can be easily pulled as the optimum position. Furthermore, in trains, buses, etc., you may sit on the seat, but even in this case, it is most ideal to move the kite by contracting the telescopic rod to make the connecting part of the sub grip optimal height. Can be limited. As described above, even if the height at which the subgrip pulls the heel body changes, the heel body can be moved and moved with light and weak force as the horizontal direction, which is the direction of movement of the heel body, at all times. Can be prevented.

  In the caster-equipped scissors according to claims 3 and 9 of the present invention, the sub grip has a loop portion formed by connecting a string in a loop shape at the tip portion. Alternatively, by inserting a hand through the loop portion, it is possible to easily and easily hold the sub grip firmly.

  In addition, according to claims 4 and 5 of the present invention, since the grip is inclined or curved in a direction in which the grip is located at the center of the bag body, the sub-grip of the string material is connected to the grip. By pulling this, the heel body can be moved smoothly in the pulling direction.

  Furthermore, the caster-equipped scissors according to claim 6 of the present invention are provided with a stopper for stopping the expansion / contraction handle at an intermediate pull-out position, so that the length of the expansion / contraction rod is adjusted so that the pull direction of the subgrip is horizontal. Then, you can stop at that position and move it by pulling the bag body. When the グ リ ッ プ body is pulled by adjusting the tensile force of the subgrip in the horizontal direction, the length of the telescopic rod does not change, and the heel body is always kept in the horizontal direction. It can move smoothly.

  Furthermore, the bag with a caster according to claim 7 of the present invention realizes an extremely excellent feature that can move easily and smoothly in a posture in which a road surface having a large road resistance is not stably tilted without enlarging the caster. This is because the heel can move the heel body by pulling the sub-grip of the string connected to the heel body, while holding the grip of the telescopic handle to hold the heel body in a posture that does not fall down. For example, as shown in FIG. 16, this moving state is a state in which the grip 4 of the extendable handle 2 is gripped with the left hand and the string material sub-grip 6 is pulled with the right hand to move the heel body 3. At this time, the bag main body 3 can be moved by both the left hand gripping the grip 4 of the extendable handle 2 and the right hand of the sub-grip 6. The scissors that are moved in this state are moved by pulling the scissors body 3 upwards somewhat with the sub grip 6 while reliably preventing the scissors body 3 from falling with the grip 4 of the extendable handle 2. The sub grip 6 that pulls the heel body 3 upward cannot use all of the tensile force to move the heel body 3. However, in places with high road surface resistance where the unevenness is large and cannot be moved smoothly, the caster can move smoothly in a state exceeding the unevenness of the road surface by moving the main body upward. However, the main body of the kite that is moved to the road with large unevenness in this state is easy to fall, but it is held so that it does not fall down by grasping the grip of the telescopic handle, so it can easily move on the road with large unevenness without falling down There are features that can be done.

  Embodiments of the present invention will be described below with reference to the drawings. However, the example shown below illustrates the bag for embodying the technical idea of the present invention, and the present invention does not specify the bag as follows.

The base frame 7 is provided with a platform 8 provided with casters 1 at four corners and mounted with a bag body 3 thereon, and the telescopic rod 5 is fixed to the side of the platform 8 so as to be self-supporting. ing. As described above, the structure in which the telescopic rod 5 is disposed on the side portion of the mounting base 8 can dispose the main body 3 on almost the entire upper surface of the mounting base 8, so that the bottom surface of the main body 3 to be mounted on the mounting base 8 can be widened. There is a feature that can be. The base frame 7 shown in the figure is the upper surface of the mounting base 8 and is mounted with the heel body 3 adjacent to the telescopic rod 5.

  A base frame 7 shown in FIG. 8 has a pair of telescopic rods 5 fixed to both ends of a side portion which is a long side of a rectangular platform 8. In the base frame 7 of FIG. 8, the telescopic rod 5 fixed to the corner of the mounting base 8 is reinforced by a reinforcing wall 9. The reinforcing wall 9 is a wall provided along both edges of the mounting base 8, and connects the telescopic rod 5 and the mounting base 8 to connect the telescopic rod 5 to the mounting base 8 so as not to fall down. The reinforcing wall 9 is integrally formed on the plastic platform 8. The base frame 7 has the heel body 3 attached to a portion surrounded by the telescopic rod 5 and the reinforcing wall 9.

  The base frame 7 shown in FIGS. 9 and 10 has a pair of telescopic rods 5 fixed to the center of the side portion that is the long side of the rectangular platform 8. The base frame 7 is provided with a support cylinder 10 that is inserted through and connected to the telescopic rod 5 and integrally formed on a plastic platform 8. In the illustrated base frame 7, two support cylinders 10 are provided on the side of the mounting base 8, and the telescopic rods 5 are inserted into and connected to the respective support cylinders 10. Furthermore, the base frame 7 shown in the drawing is provided with a support cylinder 10 protruding from the lower surface of the platform 8, and a reinforcing wall 11 is formed integrally with the protruding portion. The reinforcing wall 11 is connected to the lower surface of the support cylinder 10 and the mounting base 8. The reinforcing wall 11 is provided by effectively using the space between the casters by providing the casters 1 on the lower surfaces of the four corners of the mounting base 8. Further, the base frame 7 is provided with the support cylinder 10 and the reinforcing wall 11 by effectively utilizing the space that is lifted by the caster 1 and formed on the lower surface of the mounting base 8.

  The telescopic handle 2 is pulled upward when the bag is moved by the caster 1. When the bag is not moved by the caster 1, the extendable handle 2 is contracted and pushed. The grip 4 of the extendable handle 2 is connected to the heel body 3 via an extendable rod 5 so as to be extendable. The telescopic handle 2 shown in FIGS. 4, 5, 7 to 10 is disposed on one side (right side in the drawing) of the heel body 3, and when the telescopic handle 2 is extended and pulled up, The grip 4 is disposed so as to move from one side toward the center. As shown in the figure, when the telescopic rod 5 is fixed to one side of the rod main body 3, the center of the rod main body 3 means the center in the left-right direction.

  The telescopic handle 2 shown in FIGS. 4 and 7 to 9 is such that when the grip 4 is pulled up and the telescopic rod 5 is extended, the telescopic rod 5 is moved from one side of the heel body 3 toward the center. Is curved. The heels in these figures have the telescopic rod 5 fixed to the right side of the heel body 3 so that when the telescopic handle 2 is pulled up, the grip 4 is moved from the right side of the heel body 3 toward the left side. The rod 5 is curved. In other words, the telescopic rod 5 is curved in a direction in which the central portion protrudes outward, and the lifted grip 4 is moved from the side portion of the heel body 3 in a direction approaching the center.

  5 and FIG. 10, when the grip 4 is pulled up and the telescopic rod 5 is extended, the telescopic rod 5 is inclined so that the grip 4 is moved from one side of the heel body 3 toward the center. I am letting. 5 has the telescopic rod 5 fixed to the right side of the heel body 3, and therefore the telescopic rod 5 is inclined so that the grip 4 to be lifted moves from the right side to the left side of the heel body 3. . Further, the rod shown in FIG. 10 tilts the telescopic rod 5 so that the grip 4 to be lifted moves from the right side of the platform 8 to the left side of the telescopic rod 5 fixed to one side of the base frame 7. Yes.

  As described above, the telescopic rod 2 that is inclined or curved so that the telescopic rod 5 positions the grip 4 at the upper end in the center of the heel body 3 is not necessarily in the state where the grip 4 is lifted up. It does not have to be in the middle of This is because even if the grip is not completely centered, it can be moved forward so as not to bend the heel by pushing the grip. The position of the lifted grip 4 is, for example, 15 to 80%, assuming that one end face of the heel body in which the telescopic rod 5 is disposed is a reference 0 point and the opposite end face is 100. The position is preferably 20 to 60%, more preferably 20 to 50%.

  Further, although not shown in the drawing, the scissors can be moved from one side of the scissors body toward the center by tilting a bending telescopic rod and fixing it to one side of the scissors body, pulling up the grip. In addition to increasing the curvature radius of the heel, the heel can be brought close to a right angle and the grip can be pulled up to approach the center of the heel body. This is because the lifted grip can be moved from the side of the bag body to the center by both inclining and bending.

  Furthermore, the extendable handle 2 shown in FIG. 6 has the grip 4 disposed at the center of the upper surface of the bag main body 3. The extendable handle 2 has a linear extendable rod 5 fixed vertically at the center of the bag main body 3. In this state, the grip 4 can be arranged in the center of the main body 3 with the grip 4 pulled up.

  Since the grip 4 is located at the center of the heel body 3 with the telescopic handle 2 pulled up, the above heel has a feature that the heel can be smoothly moved by grasping the grip 4. Further, as will be described later, the hook connecting the subgrip to the extendable handle has a feature that the hook body can be smoothly moved in the pulling direction by pulling the subgrip.

  However, with the heel of the present invention, the telescopic rod is bent or inclined so that the grip is positioned at the center of the heel body, or the telescopic rod is arranged at the center of the heel body with the expansion handle pulled up. There is no need to install it. Although the extension handle is not shown, a linear extension rod can be fixed vertically to one side of the bag main body.

  When the telescopic rod 5 is in a contracted state, in other words, when the grip 4 is depressed most, the grip 4 is positioned above or above the heel body 3 and is stopped by a stopper. The telescopic rod 5 is contracted to make the grip 4 the lowest, and the distance from the bottom surface of the caster 1 to the top surface of the grip 4 is about 50 cm. However, the distance between the bottom surface of the caster and the top surface of the grip is preferably 30 to 80 cm, and more preferably 35 to 70 cm at the position where the telescopic rod is contracted to make the grip the lowest. In a state where the telescopic rod 5 is contracted to make the grip 4 the lowest, the heel body 3 is made lower than the grip 4 so that the grip 4 can be easily gripped. The telescopic rod 5 is stopped by a stopper at a position where the height from the bottom surface of the caster 1 to the center of the grip 4 is 60 to 100 cm, preferably 65 to 85 cm in the extended state, in other words, when the grip 4 is pulled up to the highest level. Is done.

  The telescopic rod 5 includes a guide cylinder 5B disposed in the vertical direction on the heel body 3 or the base frame 7, and a pull-out rod 5A inserted so as to be able to be inserted into and withdrawn from the guide cylinder 5B. A grip 4 is fixed to the upper end of the. 4, 5 and 7 are on one side of the heel body 3, the heel shown in FIG. 6 is on the center of the heel body 3, and the heels shown in FIGS. Guide cylinders 5B are fixed to the side portions of the base frame 7, respectively. The guide cylinder 5B and the extraction rod 5A can be metal cylinders having different thicknesses. However, the guide tube and the extraction rod can be manufactured by molding plastic into a rectangular tube shape.

  The telescopic rod 5 shown in FIGS. 4 to 7, 9, and 10 includes a two-stage drawing rod 5 </ b> A that is inserted so that it can be put in and out of the guide tube 5 </ b> B. The two extraction rods 5A are inserted so that the upper extraction rod 5Aa is thinner than the lower extraction rod 5Ab so that the upper extraction rod 5Aa can be inserted into and extracted from the lower extraction rod 5Ab. Further, the telescopic rod 5 is inserted so that the lower extraction rod 5Ab is thinner than the guide cylinder 5B and the lower extraction rod 5Ab can be taken in and out of the guide cylinder 5B. The telescopic rod 5 shown in these drawings has a structure that can expand and contract in two steps. However, as shown in FIG. 8, the telescopic rod 5 is provided with a one-stage pulling rod 5A that can be taken in and out of the guide tube 5B, and may have a one-stage telescopic structure. A structure that can be expanded and contracted can also be used.

  In the scissors shown in the above figures, two telescopic rods 5 are arranged on one side or the center of the scissors body 3, and the grip 4 is connected to the upper ends of the two telescopic rods 5. In the extendable handle 2 shown in FIGS. 8 to 10, the upper ends of the two guide cylinders 5 </ b> B are connected by a connecting rod 12. In the extendable handle 2 in these drawings, the lower end of the guide cylinder 5B is fixed to the platform 8 and the upper end portion is connected by the connecting rod 12. Thus, the structure which connects the upper end of the guide cylinder 5B with the connecting rod 12 can reinforce the two telescopic rods 5 and can stand more stably. Further, as shown by a chain line in FIG. 9, an insertion gap 13 for inserting a hand is provided between the grip 4 and the connecting rod 12 that are lowered most. This is to make it easier to grip the lowered grip 4. The grip 4 shown in the figure is made of plastic as a whole in a U-shape, and bent portions at both ends are connected to the extraction rod 5A to provide an insertion gap 13.

  The stopper can use any mechanism that can stop the expansion and contraction of the telescopic rod. The stopper is preferably structured so that the extendable handle can be stopped at an intermediate pulling position. This is because the expansion / contraction handle provided with the stopper of this structure can stop the expansion / contraction of the expansion / contraction rod while suitably selecting the position of the grip. The detailed structure of the extendable handle stopper will be described later.

  The sub grip 6 is a string member having a predetermined length and is connected to the extendable handle 2 or the heel body 3. The subgrip 6 connected to the extendable handle 2 is connected to the grip 4 as shown in FIGS. 4 to 10 or to the extendable rod. The sub-grip 6 connected to the grip 4 is preferably connected to the end of the grip 4. This is because the main body 3 can be smoothly moved in the pulling direction by pulling the sub grip 6. The grip 4 shown in the drawing is provided with a connecting portion 40 for connecting the sub grip 6 at the end. For example, the connecting portion 40 can be a through-hole 40A as shown in FIGS. The through hole 40 </ b> A shown in the drawing is opened by communicating the upper surface and the end surface of the grip 4. However, the through-hole 40A provided in the grip 4 can also be provided through both side surfaces of the grip 4 as shown in FIGS. The connecting portion 40 which is the through hole 40A can be provided most simply. Furthermore, the connection part 40 can also be used as the connection tools 40B and 40C provided in the grip 4, as shown in FIG. 12 and FIG. The connecting tool shown in FIG. 12 is a ring member inserted through a through hole 40 </ b> A provided in the grip 4. Furthermore, the connecting tool 40 </ b> C shown in FIG. 13 is a ring member fixed to the grip 4. The ring member fixed to the grip 4 can be fixed in a predetermined position by being embedded in the grip 4, screwed, or bonded.

  The connecting portion 40 provided at the end of the grip 4 is preferably provided at both ends of the grip 4. This is because the direction in which the cocoon is pulled differs depending on the user's dominant hand or advantage. For example, in FIG. 4, when the extendable handle 2 is pulled in the direction indicated by the arrow A, the subgrip 6 is connected to the connecting portion 40 provided at the lower left end of the grip 4 in the drawing, and the direction indicated by the arrow B When the telescopic handle 2 is pulled, the subgrip 6 is connected to a connecting portion 40 provided at the upper right end of the grip 4 in the drawing. Although the connection part 40 shown in the above figure is provided in the edge part of the grip 4, a connection part can also be provided in the center part of a grip.

  Moreover, the subgrip 6 connected to the telescopic rod 5 can be coupled in a state of being wound around the telescopic rod 5 as shown in FIG. The sub-grip 6 shown in the drawing includes a connecting member 46 at the connecting end. The connecting member 46 shown in the figure is a connecting loop portion 46A formed by connecting thin wires in a loop shape. The subgrip 6 shown in the figure is a wire rod by winding the connecting loop portion 46A along the periphery of the telescopic rod 5 and inserting and pulling the body portion of the subgrip 6 at the tip of the wound connecting loop portion 46A. The connecting member 46 is wound around the telescopic rod 5 and connected. This connection structure has a feature that the sub grip 6 can be connected to the telescopic rod 5 easily and easily. Further, the subgrip can be coupled to the grip by the coupling structure shown in the drawing. However, the subgrip can be connected via the connecting portion by providing a connecting portion such as a through hole or a connecting tool on the telescopic rod. In this way, the structure in which the sub grip 6 is connected to the telescopic rod 5 is substantially the same as when the sub grip is connected to the end of the grip, and the sub grip 6 is pulled to smoothly move the heel body in the pulling direction. It has the feature that it can be moved and the movement of the bag body can be restricted.

  Further, the subgrip 6 connected to the bag main body 3 is connected to the main body portion 3A as shown by a chain line in FIGS. The subgrip 6 connected to the heel body 3 is preferably an end portion in the front-rear direction of the main body portion 3A (directions indicated by arrows A and B in FIG. 4) and is connected to the upper portion. That is, it connects with the vicinity of the corner part of the upper both ends of the collar body 3. The bag main body 3 shown in these drawings is provided with a connecting portion 41 for connecting the sub grip 6 to the corner portions at both upper ends. The connecting portion 41 is preferably provided at the center of the left and right sides of the bag main body 3. This is to make it easier to move the bag by pulling the sub grip 6. The connection part 41 can be made into the connection tool 41A fixed to 3 A of main-body parts, for example. The connecting portion 41 shown in FIGS. 4 to 6 connects the connecting tool 41A as a metal or plastic ring member to the surface of the bag main body 3 via a connecting piece 42. The connecting portion 41 shown in FIG. 7 is a connecting convex portion 41 </ b> B formed integrally with the heel body 3. Furthermore, the connection part 41 shown in FIG. 8 thru | or FIG. 10 is connected with the collar main body 3 via the connection piece 42 as the loop part 41C formed with the cloth and the string. The connecting end of the subgrip 6 is connected to these connecting portions 41 to connect the subgrip 6 to the bag main body 3. The connecting portions 41 provided on the heel body 3 are also preferably provided on both the front and back sides of the heel body 3. This is because, as described above, the direction in which the cocoon is pulled differs depending on the user's dominant hand or advantage. For example, in FIG. 4, when the heel body 3 is pulled in the direction indicated by the arrow A, the subgrip 6 is connected to the connecting portion 41 provided at the lower left end in the drawing, and the heel body is formed in the direction indicated by the arrow B. When pulling 3, the subgrip is connected to a connecting portion (not shown) provided at the upper right end in the drawing.

  However, the bag main body does not necessarily need to be provided with a dedicated connecting portion. For example, in addition to the grip 4 of the extendable handle 2, the heel body 3 shown in the figure has a grip portion 43 that can carry the heel body 3 by hand on the upper surface or end surface of the heel body 3. The grip portion 43 can be used as a connecting portion of the sub grip 6. For example, the grip portion 43 of the heel shown in FIGS. 4 to 6 has both ends of the grip portion 44 connected to the heel body 3 via the connection ring 45. It is also possible to connect the sub grip 6 to the connecting ring 45 by using the connecting ring 45 in combination with the connecting portion of the sub grip 6. The bag main body 3 shown in the figure has grip portions 43 on both the upper surface and the end surface. Therefore, this bag is used by connecting the sub grip to the connection ring 45 of the grip portion 43 on the upper surface of the bag body 3 or connecting the sub grip 6 to the connection ring 45 above the grip portion 43 located on the end surface. it can. However, the subgrip can be connected to the grip portion of the grip portion.

  Furthermore, the bag of this invention does not specify the connection part provided in a telescopic handle or a bag main body to the above structure. In the present invention, connecting portions having various shapes and structures capable of connecting the subgrip can be provided on the extendable handle or the bag main body.

  The sub grip 6 is preferably connected to the extendable handle 2 or the heel body 3 so as to be detachable. However, the subgrip can also be fixed to the telescopic handle or the bag body so that it cannot be detached. The subgrip 6 shown in the drawing includes a connecting member 46 at a connecting end in order to be detachably connected to the telescopic handle 2 or the heel body 3. The sub-grip 6 shown in FIGS. 4 to 11 and FIG. 14 is provided with a connecting loop portion 46A formed by connecting a thin wire rod in a loop shape at the tip, and this connecting loop portion 46A is connected to the grip 4 of the extendable handle 2. Or it is connected to the telescopic rod 5. The connecting member 46 is formed by inserting the main body portion of the sub grip 6 at the tip of the connecting loop portion 46A inserted through the connecting portion 40 which is a through-hole or a ring portion, or as shown in FIG. 46A is wound along the periphery of the telescopic rod 5, and the main body portion of the subgrip 6 is inserted and pulled inside the front end of the wound coupling loop portion 46A, so that the coupling member 46, which is a wire, can be easily stretched. Can be linked. The sub grip 6 shown in the figure connects the connecting member 46, which is a wire, to the extendable handle 2. However, the connecting member, which is a wire, can also be connected to the connecting portion of the bag main body.

  Further, the connecting member 46 may be a detachable connecting tool 46B as shown in FIGS. The detachable connector 46B shown in the figure has a hook part that can be opened and closed or a detachable ring part, and the hook part or ring part is inserted into and connected to the connecting parts 40 and 41 of the telescopic handle 2 or the bag main body 3. Yes. The connecting portions 40 and 41 of the telescopic handle 2 or the heel body 3 to which the detachable connecting tool 46B is connected are, for example, the connecting tools 40B and 40C provided on the grip 4 of the telescopic handle 2 as shown in FIG. It can be set as the connection tool 41A provided in the main-body part 3A of the main body 3, the connection convex part 41B, or the loop part 41C. The sub grip 6 having the detachable connector 46B has a feature that it can be easily detached.

  The string material of the subgrip 6 has a predetermined length and strength that can be moved by pulling from a distant position while being connected to the telescopic handle 2 or the heel body 3, or the movement can be restricted. The string of the subgrip 6 can have a total length of 10 cm to 90 cm. As shown in FIG. 15 and FIG. 16, the string material connected to the grip 4 of the extendable handle 2 changes the stop position of the grip 4 with the extendable rod 5 so that the connecting position of the sub grip 6 is increased. Therefore, the total length can be conveniently used as 10 to 50 cm. Further, as shown in FIG. 17, the string material connected to the heel body 3 is used in a state where the hand is in a standing state so that the heel body 3 can be pulled by using the grip 4 in the most extended state. It can be conveniently used with a total length of 20 cm to 90 cm so that the length is up to 20 cm.

  As the string material of the subgrip 6, for example, natural fibers or synthetic fibers knitted into a string shape, or those woven into a string shape or a band shape can be used. As natural fibers, vegetable fibers such as cotton and animal fibers such as silk can be used. As the synthetic fiber, a fiber obtained by spinning a polymer compound, for example, polyester, polyamide, acrylic fiber, or the like can be used. A cord material made by knitting a synthetic fiber such as polyester in a string shape or woven in a string shape or a band shape has a feature that it is easy to touch, strong, and can be manufactured at low cost because it can reduce manufacturing costs. In particular, a braid made from a synthetic fiber bag is strong, strong against tension, and stretchable, so that it can be suitably used as a sub-grip string material.

  However, other than these, for example, a chain formed by connecting a large number of metal or plastic rings, or plastic, cloth, leather, etc., in the form of a thin and flexible band It is also possible to use a molded tape or belt, or a wire formed by forming a plastic into a flexible linear shape. Therefore, in the present specification, the string material is not only a knitted or woven plastic fiber, thread, cloth, paper, leather, etc., but also a strip-like tape, belt, chain, wire, etc. Is used in a broad sense including etc.

  The sub-grip 6 connects the connecting end to the telescopic handle 2 or the heel body 3, and restricts the movement of the heel body 3 by grasping the opposite end, or pulls the heel body 3 to move. The subgrip 6 shown in the drawing is provided with a loop portion 6A formed by connecting a string material in a loop shape at the end opposite to the connecting end. This subgrip 6 can hold the subgrip 6 easily, easily and firmly by grasping the loop portion 6A or inserting a hand through the loop portion 6A.

  The bag having the above structure uses the sub grip 6 as follows. The heel formed by connecting the subgrip 6 to the grip 4 of the extendable handle 2 can adjust the height of the grip 4 according to the use state of the user. It can arrange | position in the state match | combined with the horizontal direction which is a moving direction of. For example, as shown in FIG. 15, when the user is standing, the telescopic rod 5 of the telescopic handle 2 is extended to adjust the position of the grip 4 to the height of the hand, and the sub grip 6 is pulled in a horizontal direction. To be. For example, in the case of a tall person, the grip 4 is pulled out to a high position, and in the case of a short person, the grip 4 is pushed down to a low position so that the connecting position of the sub grip 6 is the highest. It can be close to the hand position. The sub grip 6 close to the position of the hand can be held by the hand in the most comfortable posture, can move the heel with the least force, and can move by pulling the heel. Furthermore, as shown in FIG. 16, when the user is sitting on a seat or the like, the telescopic rod 5 of the telescopic handle 2 is contracted to adjust the position of the grip 4 to the height of the hand in the seated state. By making the pulling direction a horizontal direction, it is possible to have the sub grip in the most comfortable posture and to limit the movement of the eyelid with the least force. In this way, the structure in which the sub grip 6 is connected to the grip 4 of the extendable handle 2 that can be expanded and contracted vertically can move the heel with the least force while keeping the position of the grip 4 at an optimum height, and can also restrict the movement. Can be retained.

  Further, the bag formed by connecting the sub grip 6 to the bag body 3 is used as shown in FIG. This figure shows a state in which the grip body 4 is moved by holding the grip 4 of the telescopic handle 2 with the left hand and pulling the sub-grip 6 of the string material with the right hand. In this moving state, the heel body 3 can be moved by both the left hand that grips the grip 4 of the extendable handle 2 and the right hand of the sub-grip 6. For this reason, while reliably preventing the heel body 3 from falling with the grip 4 of the extendable handle 2, the heel body 3 is pulled upward and moved with the sub-grip 6 so that the road surface with a step or the like falls stably. It can move easily and smoothly with no posture.

  Furthermore, a heel that can be detachably connected to a subgrip handle or a heel body can be used ideally by changing the position of the subgrip according to the application. In other words, in the state where it is connected to the telescopic handle, the movement of the heel body is restricted with the least force, or the heel body is pulled and moved. You can move easily while holding.

  Hereinafter, an example of the stopper of the extendable handle will be described with reference to the drawings. Since the telescopic rod 5 shown in FIGS. 18 to 20 has a structure in which the two-stage pulling rod 5A can be expanded and contracted, the upper and lower two stoppers 15 are provided. The first stopper 15A stops the expansion and contraction of the upper extraction rod 5Aa and the lower extraction rod 5Ab. The second stopper 15B stops the extension of the lower extraction rod 5Ab and the guide cylinder 5B. Further, the contraction of the lower extraction rod 5Ab and the guide cylinder 5B is stopped by the first stopper 15A.

  The first stopper 15A is disposed at the lower end of the upper extraction rod 5Aa, and is provided on the protrusion pin 16 that elastically protrudes toward the lower extraction rod 5Ab and the lower extraction rod 5Ab. The locking part 17 into which 16 is inserted, and the 1st cancellation | release mechanism 18 which forcibly pulls out the protrusion pin 16 from the locking part 17 are provided. The second stopper 15B is disposed at the lower end portion of the lower extraction rod 5Ab and is provided on the guide cylinder 5B and the protrusion pin 36 that elastically protrudes toward the guide cylinder 5B. The protrusion pin 36 is inserted into the second stopper 15B. And a second release mechanism 38 that forcibly pulls out the protruding pin 36 from the locking portion 37.

  The protruding pin 16 is disposed inside the lower end portion of the upper extraction rod 5Aa via an elastic member 19 so as to elastically protrude in the outer peripheral direction of the extraction rod 5A. The protruding pin 36 is disposed inside the lower end portion of the lower extraction rod 5Ab via an elastic member 39 so as to elastically protrude in the outer peripheral direction of the extraction rod 5A. These protruding pins 16 and 36 are pressed by the elastic members 19 and 39 and elastically protrude from the extraction rod 5A. The projecting pins 16 and 36 are arranged on the extraction rod 5A so as to project in opposite directions. In the illustrated telescopic rod 5, the projecting pin 16 projects inward, that is, in the direction of the opposing telescopic rod 5, and the projecting pin 36 projects outward, that is, in the direction opposite to the opposing telescopic rod 5.

  The locking portions 17 and 37 are through holes or recesses into which the protruding pins 16 and 36 are inserted. The lower drawing rod 5Ab and the guide cylinder 5B shown in the drawing have through holes through which the projecting pins 16 and 36 are inserted to form locking portions 17 and 37, respectively. As described above, the structure having the locking portions 17 and 37 as the through holes has a feature that the projecting pins 16 and 36 inserted therein are protruded through the through holes so that the telescopic rod 5 can be stopped reliably. . In particular, this can be used very safely when the telescopic rod 5 is used instead of a cane, and in other words when the body is supported as a posture to put weight on the grip 4. This is because it is possible to effectively prevent the protruding pins 16 and 36 from being unexpectedly detached from the locking portions 17 and 37 and the telescopic rod 5 being pushed in. In addition, there is also an advantage that the telescopic rod 5 can be prevented from being pulled out unexpectedly when the entire bag is lifted with the grip 4. As described above, the stopper 15 that can reliably fix the position of the pull-out rod 5A has an advantage that it can be used extremely safely regardless of whether the grip 4 is in the raised position or the lowered position. However, the locking portion can be a recess into which the tip of the protruding pin is inserted.

  Although not shown, the locking portion 17 provided in the lower extraction rod 5Ab inserts the protruding pin 16 in a state where the upper extraction rod 5Aa is pulled up most, a state where it is pulled up to the middle, and a state where it is lowered most. It is provided at a plurality of positions. When the upper drawing rod 5Aa is pulled up most, the protruding pin 16 is inserted into the uppermost locking portion 17, and when the upper drawing rod 5Aa is moved down most, the protruding pin 16 protrudes into the lowermost locking portion 17. In a state where the pin 16 is inserted and the upper extraction rod 5Aa is pulled up to the middle, the protruding pin 16 is inserted into the intermediate locking portion 17, and the expansion and contraction of the upper extraction rod 5Aa is stopped. Thus, the telescopic rod 5 provided with the locking portion 17 in the middle of the lower extraction rod 5Ab has the feature that the upper extraction rod 5Aa can be expanded and contracted in a plurality of stages. In particular, the telescopic rod 5 provided with a plurality of locking portions 17 in the middle of the lower drawer rod 5Ab can stop the upper drawer rod 5Aa pulled up to the middle at a plurality of lifting positions, so that the position of the grip 4 is moved up and down little by little. There is a feature that allows you to select the optimal position. However, the upper drawing rod does not necessarily need to have a structure that can be stopped at the intermediate position, and can be stopped only at the raised position and the lowered position.

  The locking portion 37 provided in the guide cylinder 5B is provided at a position where the protruding pin 36 is inserted in a state where the lower extraction rod 5Ab is pulled up most. In a state where the lower extraction rod 5Ab is pulled up most, the protruding pin 36 is inserted into the locking portion 37, and the extension of the lower extraction rod 5Ab is stopped. Further, the guide tube can be provided with a plurality of locking portions at positions where the protruding pins are inserted in a state where the lower extraction rod is pulled up to the middle. This telescopic rod also has the feature that the lower pulling rod that has been pulled up to the middle can be stopped at a plurality of pulling positions, so that the optimum position can be selected by gradually moving the grip up and down.

  Further, as shown in FIG. 19, the guide cylinder 5B is provided with a locking portion 30 into which the protruding pin 16 is inserted in a state where the upper extraction rod 5Aa and the lower extraction rod 5Ab are lowered most. The locking portion 30 is provided at a position where the protruding pin 16 penetrating the lowest locking portion 17 of the lower extraction rod 5Ab in the lowered position is inserted. In other words, the telescopic rod 5 is connected to the locking portion 17 of the lower drawing rod 5Ab and the locking portion 30 inside the guide cylinder 5B with the upper drawing rod 5Aa and the lower drawing rod 5Ab lowered most. The protruding pin 16 is inserted and the telescopic rod 5 is stopped in the most contracted state. Thus, the protruding pin 36 is inserted into the locking portion 37 provided outside the guide tube 5B, and the extension of the lower extraction rod 5Ab is stopped, and the protruding portion 36 protrudes into the locking portion 30 provided inside the guide tube 5B. The pin 16 is inserted, and the contraction of the lower extraction rod 5Ab is stopped.
