Description

The present invention relates to wheeled luggage, it relates to a bag having a handle especially stretching up and down.

  Casters with casters that can be pulled out have already been developed and used. There are many types of kites of this structure that are large enough to be brought into an aircraft or slightly larger than this. For example, U.S. Pat. No. 4,995,487 (Patent Document 1), Japanese Patent Publication No. 4-76686 (Patent Document 2), Japanese Utility Model Publication No. 57-179824 (Patent Document 3), and Japanese Utility Model 63-131634 (Patent Document 4). The scissors described in these publications are provided with two casters 41 on one side of the bottom as shown in FIG. A short leg 42 is fixed to the opposite side of the caster 41. When the heel is raised vertically, the casters 41 and the legs 42 come into contact with the floor. In this state, since the leg 42 which does not rotate contacts, the heel is self-supporting vertically without moving. Furthermore, a handle 43 is provided so that it can be pulled out to the upper surface in order to pull and move the bag. The handle 43 is provided on the same side as the caster 41 because the handle 43 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 43. When the heel is tilted, the caster 41 comes into contact with the floor and the legs 42 move away from the floor. When the handle 43 is pulled in this state, the caster 41 rotates and can be moved easily. However, there are cases in which the casters 41 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 41, the lateral width of the kite increases, and it is not possible to move freely in a narrow passage between seats in the cabin or in crowded places. When the caster 41 cannot be used, it is necessary to lift and move the bag by hand. When it is lifted and moved by hand, it can move in the direction indicated by arrow A in FIG.

  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 of this figure has a caster 41 attached to the bottom surface of the case main body 44. The casters 41 are provided at the four corners of the bottom surface so that the case main body 44 can stand upright in a vertical posture. The grip portion 43 </ b> A of the handle 43 is located above the case main body 44 and at the center of its 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, when the free casters that can move in any direction are used for the four casters 41, 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 43. 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 handle of this structure has a handle attached at the center, it is necessary to fix the telescopic rod 45 of the handle 43 inside the case body 44 as shown in the cross-sectional view of FIG. The telescopic rod 45 is fixed in a state of penetrating the left and right sides of the case body 44, that is, the center in the thickness direction, in order to dispose the grip portion 43 </ b> A at the left and right centers of the case body 44. In the bag having this structure, it becomes difficult to effectively use the inside of the case main body 44 because the telescopic rod 45 becomes an obstacle.

  The present inventor has developed a bag shown in FIG. 4 for the purpose of solving these drawbacks (see Patent Document 6).

In this case, casters 41 are provided at the four corners of the bottom surface of the case main body 44, and a telescopic rod 45 is fixed to the side surface of the case main body 44. The telescopic rod 45 has a structure that allows the handle 43 to be pulled upward, and is provided with a grip 43A at the upper end. The telescopic rod 45 is curved so that the grip portion 43 </ b> A is positioned at the center of the left and right of the upper surface of the case body 44 in a state where it is pulled up from the case body 44.
US Pat. No. 4,995,487 Japanese Examined Patent Publication No. 4-76686 Japanese Utility Model Publication No. 57-179824 Japanese Utility Model Publication No. 63-131634 JP-A-10-117829 Japanese Patent Laid-Open No. 10-137022

  This structure has a feature that the inside of the bag body can be deepened because the telescopic rod is fixed to the side. However, since the scissors with this structure are fixed to the scissors body with a telescopic rod, it is necessary to make the scissors body a strong structure. This is because the telescopic rod is self-supporting in the bag body. As shown in FIG. 1, the heel of this structure does not pull and move the telescopic rod, but is used as a walking stick to support the pedestrian and is pushed forward to move the heel body. Structure is required. For this reason, it is necessary to reinforce the attachment part of the rod main body and the telescopic rod in order to make the telescopic rod firmly stand on the rod main body. For this reason, there has been a drawback that the structure of the bag main body is complicated and the manufacturing cost is remarkably increased. Further, the bag main body has a drawback that it is difficult to reinforce the tough structure without reducing the storage space.

  The present inventor has further developed a bag shown in FIG. 5 in order to solve this drawback. This saddle is mounted so that the saddle main body 53 can be attached to and detached from a base frame 51 provided with casters 56 that can run in free directions at the four corners of the bottom surface. The base frame 51 has a platform 52 on which the bag body 53 is mounted, an extendable rod 55 that can be pulled out upward and has a grip 54 at the upper end, and holds the extendable rod 55 in the extended position and the contracted position. And a stopper (not shown). The platform 52 is provided with casters 56 at four corners. The telescopic rod 55 is fixed to one side of the mounting base 52 so as to extend upward and to be self-supporting. The bag main body 53 is connected to the base frame 51 by being mounted on the side surface of the telescopic rod 55 on the mounting base 52.

  The heel of this structure cannot prevent the extension rod 55 from falling over by the heel body 53 as in the prior art. For this reason, the base frame 51 needs to be connected to the mounting base 52 with a strong structure that does not allow the telescopic rod 55 to fall down firmly. In order to realize this, the base frame 51 has the telescopic rod 55 fixed to the corner of the mounting base 52, and the telescopic rod 55 is reinforced by the reinforcing wall 58. The reinforcing wall 58 is a wall provided along both end edges of the mounting base 52, and connects the telescopic rod 55 and the mounting base 52, and connects the telescopic rod 55 to the mounting base 52 so as not to fall down. In the base frame 51, a heel body 53 is attached to a portion surrounded by the telescopic rod 55 and the reinforcing wall 58. The mounting table 52 and the reinforcing wall 58 are manufactured by integrally molding with a light metal such as plastic or aluminum.

  The ridges of this structure are connected to the platform so that the telescopic rods cannot fall down with the reinforcing walls. However, since the reinforcing wall is provided along the both edges of the mounting base, it is necessary to mount the bag main body between the reinforcing walls at both ends. This limits the size, design, etc. of the heel to be placed on the platform because the distance between the pair of reinforcing walls specifies the width of the heel body.

  The present inventor further developed a bag shown in FIG. 6 to solve this problem. Similar to the bag shown in FIG. 5, the bag includes a base frame 61 having casters 66 and a bag body 63. The difference from the heel shown in FIG. 5 is the formation position of the reinforcing wall 68, and the reinforcing wall 68 in the heel shown in FIG. 6 is provided below the mounting table 62. The reinforcing wall 68 will be described with reference to FIG. 7 which is a bottom perspective view of the base frame 61. The reinforcing walls 68 are disposed between the casters 66 provided at the four corners on the bottom surface side of the mounting table 62, and are configured by connecting a horizontal reinforcing wall 68A and a vertical reinforcing wall 68B. Further, the reinforcing wall 68 protrudes from the lower surface of the mounting table 62, and the protruding height d is lower than the height h of the caster 66.

  By thus providing the reinforcing wall 68 so as to protrude below the mounting table 62, the base frame 61 can have a strong structure. As a result, since the reinforcing wall on the upper surface side of the mounting table 62 can be omitted, there is no spatial limitation on the upper surface side of the mounting table 62, and the options of the rod main body 63 to be mounted are expanded.

  However, according to the cage in FIG. 6, casters 66 are provided at the four corners of the bottom surface of the platform 62, and therefore the reinforcing walls 68 provided on the bottom surface side of the platform 62 are installed so as to avoid the mounting position of the casters 66. There is a need to. Therefore, although it will be arrange | positioned between the casters 66, this will also restrict | limit the installation position of the support cylinder 67 connected with the reinforcement wall 68 and extended above the mounting base 62. FIG. As a result, the position of the telescopic rod 65 that is inserted through and connected to the support cylinder 67 and the grip 64 provided at the upper end of the telescopic rod 65 is also limited. Then, when the distance between the casters 66 is relatively small, the separation distance L of the telescopic rod 65 is further reduced according to the reinforcing wall 68 installed between the casters 66, and therefore the length of the grip 64 is also shortened.

  The grip 64 having a short grip area is difficult to grip. In addition, force is applied to a narrow area of the side surface of the kite, making it difficult to control the kite. As a result, it is difficult to control the traveling direction of the kite because it is difficult to push the kite. Moreover, there was a possibility that the balance would be lost and the cocoon would fall easily.

The present invention was further developed to solve this drawback, and one object of the present invention is to provide a caster-equipped scissors that reinforces the telescopic rods and makes it easy to control the travel of the scissors. It is in.

The bag with casters of the first invention has a bag body 3 and a base frame 1 that can carry the bag body 3. The base frame 1 includes a mounting surface 2 on which the main body 3 is detachably mounted, a caster 6 that is fixed to a bottom surface facing the mounting surface 2 and travels the base frame 1 in a free direction, and a mounting surface 2. A hollow support cylinder 7 that is connected to at least a part of one of the two sides and protrudes substantially perpendicularly to the side facing the caster 6 via the mounting surface 2, and is inserted into the support cylinder 7. A telescopic rod 5 which is connected so as to be self-supporting in a posture extending in a direction away from the mounting surface 2 and is extendable in a direction away from or close to the mounting surface 2 and provided with a grip 4 at one end; And a stopper 15 for stopping the telescopic rod 5 at the extended position .

  The cage with a caster according to the sixth aspect of the invention is characterized in that the outer diameter of the support cylinder 7 increases as it approaches the placement surface 2.

  The cage with casters of the seventh invention is characterized in that the casters 6 are located in a substantially vertical direction of the support cylinder 7.

  The cage with casters according to the eighth invention is characterized in that the support cylinder 7 is provided at the corner of the mounting surface 2.

  The cage with a caster according to the ninth aspect of the invention has an insertion band 40 in which the bag body 3 opens in the expansion / contraction direction of the expansion / contraction rod 5 and through which the expansion / contraction rod 5 can be inserted. The bag main body 3 is configured to be removable from the base frame 1 by being inserted.

The cage with a caster according to the present invention is characterized in that, in a posture in which the grip 4 is pulled up, the telescopic rod 5 is curved or inclined in a direction decentered from one side of the mounting surface 2 toward the center.

In the cage with a caster according to the present invention, the base frame 1 has two support cylinders 7 on one side of the mounting surface 2, and two extension rods 5 are connected to the two support cylinders 7, so that the two extension cylinders are provided. The grip 4 is connected to the upper end of the rod 5.

Base over the scan frame is provided with a platform 102 for mounting detachably the bag 3, the platform 102 has a planar carriage plate 9. The support cylinder 7 is connected so as to extend substantially upward from both ends on one side of the mounting plate 9, and the mounting table 102 has lateral reinforcing ribs 112 </ b> A that extend laterally on the lower surface of the mounting plate 9 and project downward. It is formed integrally. Further, the lateral reinforcing rib 112A protrudes downward from a region located below the support tube 7 to form a reinforcing protruding portion 108 .

The cage with casters according to the tenth aspect of the present invention has a bottom surface 2A that faces the mounting surface 2 and a side surface 2B that constitutes the thickness of the mounting plate 9, with the mounting plate 9 having one main surface as the mounting surface 2. In addition, the reinforcing protrusion 108 is provided below the junction point D where the placement surface 2 and the rising portion of the support cylinder 7 are joined in a plan view from the side surface 2B.

The cage with casters of the eleventh aspect of the invention further includes a caster 6 that is fixed to the bottom surface 2 </ b> A and allows the base frame to travel in any direction, and the reinforcing protrusion 108 is within the rotation area of the caster 6. It is characterized by being disposed apart from the wheel 114 connected to the wheel.

In the casket with a caster according to the twelfth aspect , the platform 102 is provided with two rows of lateral reinforcing ribs 112A and 112B in parallel to each other at the connecting portion of the support cylinder 7, and between the two rows of lateral reinforcing ribs 112A and 112B. One or more rows of bottom reinforcing ribs 208 are integrally formed so as to protrude downward on the lower surface of the mounting plate 9.

The scissors with casters according to the thirteenth aspect have both ends connected to the two rows of lateral reinforcing ribs 112A and 112B, and are located below the support cylinder 7, and integrally formed with connecting ribs 110A on the lower surface of the mounting plate 9. and it provided Te, characterized by a not provided Turkey by connecting the bottom rib 208 in the connection rib 110A.

When Ru good to wheeled luggage of the present invention, there is provided a rising portion of the support tube which projects substantially perpendicularly to the side that casters facing through the mounting surface, connecting the surface mounting this support cylinder A reinforcing wall is formed as described above. Further, the reinforcing wall is connected to only one side of the mounting surface to which the supporting cylinder is connected, and the supporting cylinder and the reinforcing wall are located in substantially the same plane. That is, by forming the reinforcing wall on the support cylinder side of the mounting surface, it is possible to avoid forming the reinforcing wall on the bottom surface side, and therefore, it does not become a barrier to the installation of other components provided on the bottom surface side. That is, the installation position of the parts on the bottom side can be freely set. In addition, the contact between the bottom surface of the placement surface and the traveling road surface can be reduced so that the bag can be moved smoothly.

In particular , the protruding members are assembled on one side of the mounting surface by projecting the support cylinder and the reinforcing wall of the base frame in a substantially vertical posture from one side of the mounting surface and in a substantially identical plane. In other words, the partition on the placement surface can be reduced to make the space region wide, and as a result, the types of bag bodies that can be placed can be varied.

In addition , by adopting a configuration in which the corner portion constituted by the placement surface and the support tube is reinforced, the joint region between the placement surface and the support tube, where stress is likely to occur, can be made strong. As a result, since the load on the joining region can be reduced, a base frame having a tough frame structure that prevents deformation of the support cylinder 7 due to pressing can be obtained.

Moreover , the space between the support cylinders can be effectively used by configuring the reinforcing wall between the plurality of support cylinders. In other words, the reinforcing wall has a form that partially fills the space of the protruding structure above the mounting surface, and the protruding area is located on the mounting side of the support cylinder without increasing the overall width of the protruding area. Can be aggregated. That is, it is possible to secure a wide space by reducing the spatial partition on the upper surface side of the placement surface while realizing the reinforcement of the base frame. As a result, the restrictions on the main body that can be placed on the placement surface can be greatly reduced, and the range of selection can be expanded particularly in terms of size.

  Further, since the reinforcing wall is located at the rising portion of the support cylinder, it can be formed regardless of the connection position of the support cylinder on the placement surface. That is, the position where the reinforcing wall is formed does not specify the position of the support cylinder. Therefore, the connection position between the mounting surface and the support tube and the length of the grip connected to the support tube can be freely designed. As a result, it is possible to adjust the structure so that the bag can be easily transported.

According to the caged casters of the fifth and sixth inventions, the support cylinder can be reinforced in the front-rear and left-right directions to be even stronger.

According to the caster-equipped scissors of the seventh and eighth inventions, the telescopic rod can be made to stand firmly and support the load of the transporter stably. In addition, the transporter can easily control the traveling direction of the kite and can move easily.

According to a ninth shot Akira of wheeled luggage, it can be easily detached and the bag body and the base frame.

Further , according to the cage with a caster according to the present invention, the base frame has the reinforcing protrusion that protrudes in the direction opposite to the extending direction of the support cylinder from the mount, thereby lacking the mounting area on the mounting surface of the mount. The base frame can be reinforced from the bottom side of the platform. That is, the base frame can be strengthened while maintaining a sufficient placement area for the bag main body. In particular, by increasing the protruding amount of the bottom reinforcing wall 108 at the joint point D between the mounting surface and the support cylinder, it is possible to improve the impact resistance in the joint area between the platform and the support cylinder that are easily stressed. In addition, by arranging the bottom reinforcing wall away from the wheels of the casters, smooth rotation of the casters can be maintained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies the casket with casters and the base frame constituting the casket for embodying the technical idea of the present invention.

(Embodiment 1)
FIG. 8 shows an exploded perspective view of the caster-equipped scissors 100 according to the first embodiment (hereinafter sometimes simply referred to as “claw”). Further, FIG. 9 shows a side view of the state in which the bag main body 3 is mounted on the mounting surface 2. The caster-equipped scissors 100 are mainly composed of a scissors main body 3 and a base frame 1 that can carry the scissors main body 3. The base frame 1 has a mounting surface 2 on which the bag main body 3 is detachably mounted. At the four corners on the bottom surface side of the mounting surface 2, swing-type casters 6 that can run in any direction are provided. Further, the base frame 1 has a hollow support cylinder 7 that is erected substantially vertically from the placement surface 2 in an upward direction in at least a partial region on one side of the rectangular placement surface 2. A telescopic rod 5 that can be vertically expanded and contracted is inserted into the hollow of the support tube 7, and the telescopic rod 5 is connected to the support tube 7 so as to be self-supporting in an upwardly extending posture. The base frame 1 also has a stopper 15 (see FIG. 20) that stops the telescopic rod 5 at the extended position. Further, a grip 4 is provided at the upper end of the telescopic rod 5, and the carrier can hold the grip 4 and move the heel 100 in a desired direction. As will be described in detail later, the bag 100 has a feature that the bag body 3 can be easily replaced. When the various heel main bodies 3 are mounted on the base frame 1, the heel main body 3 is placed on the placement surface 2, and the heel main body 3 is fixed in a posture along the side surface of the telescopic rod 5.

  In the examples of FIGS. 8 and 9, the planar shape of the mounting surface 2 is a rectangle. The mounting surface 2 has one support cylinder 7 fixed to each end of one side which is one long side of the rectangle. The support cylinder 7 extends from the upper surface of the mounting surface 2 upward, that is, substantially in the normal direction of the mounting surface 2, and is provided integrally with the mounting surface 2. That is, the support cylinder 7 protrudes upward from the upper surface of the mounting surface 2 and does not protrude toward the bottom surface side. As a result, the lower end of the support cylinder 7 does not interfere with the traveling road surface and hinders the traveling of the eaves 100, and can move smoothly even on a traveling road surface having a slight level difference.

  Further, since the caster 6 and the support cylinder 7 are separately provided on the front and back surfaces of the placement surface 2, they can be positioned freely on each surface without depending on the formation positions thereof. That is, since the caster 6 and the support cylinder 7 are not installed on the same surface of the mounting surface 2, it is not necessary to provide the support cylinder 7 so as to avoid the fixing position of the caster 6. In the example of FIGS. 8 and 9, the support cylinder 7 and the casters 6 are both located at the corners of the placement surface 2, in other words, the casters 6 are mounted in a substantially vertical direction of the support cylinder 7. Thereby, since the force applied to the grip 4 is linearly conducted from the support cylinder 7 to the caster 6, the moving direction of the caster can be easily controlled, and the stability of the bag is increased. Moreover, the force required for the movement of the bag can be reduced, which is preferable.

  FIG. 10 is a perspective view of the base frame 1 as viewed from the placement surface 2 side. As shown in FIG. 10, the base frame 1 is a reinforcing wall that connects the support cylinder 7 and the mounting surface 2 at a rising portion of the support cylinder 7 that protrudes substantially vertically upward from the upper surface of the mounting surface 2. 8 is provided. The reinforcing wall 8 is connected only to the same one side to which the supporting cylinder 7 on the mounting surface 2 is connected, and the supporting cylinder 7 and the reinforcing wall 8 are located in substantially the same plane. That is, both the support cylinder 7 and the reinforcement wall 8 are disposed in a plane orthogonal to the upper side from one side of the placement surface, and the thicknesses of the support cylinder 7 and the reinforcement wall 8 are connected to each other. More specifically, the reinforcing wall 8 is formed at a position that fills the corner in the joining region in which the mounting surface 2 and the support cylinder 7 are configured to be substantially orthogonal to each other. Moreover, in the example of FIG. 10, the two support cylinders 7 are spaced apart in parallel, and the reinforcing wall 8 is located within this spacing. That is, the reinforcing wall 8 is between the two support cylinders 7 erected upward from both ends on one side of the placement surface 2, and is surrounded by the placement surface 2, the support cylinder 7 and the telescopic rod 5. Provided in a rectangular rod frame 29. The reinforcing wall 8 is preferably formed integrally with the mounting surface 2 and the support cylinder 7 from the viewpoint of strength.

  Furthermore, the reinforcement wall 8 can be provided in one place or a plurality of places in the corner of the rod frame 29 as shown in FIG. The shape of the reinforcing wall 8 in this case has an area that can compensate at least the corners of the rod frame 29 and can substantially connect adjacent sides of the rod frame 29 substantially orthogonal to each other. Specifically, as shown in the figure, in addition to the triangular shape according to the shape of the corner of the rod frame 29, a polygonal shape, or a curved line or step such as a wavy line or an arc shape on the opposite side of the right corner It can be in various shapes such as a stepped shape. In addition, it is good also as a shape which bridge | crosslinks and connects the support cylinders 7 which are in the rod frame 29 and which oppose. Further, the reinforcing wall 8 can be reduced in weight by opening the inside in a dot shape while maintaining the overall shape.

  By providing the reinforcing wall 8 in this way, the strength of the support cylinder 7 and the telescopic rod 5 is increased. In particular, by reinforcing the corners of the rod frame 29, which is the rising portion of the support cylinder 7, the rod frame 29 can be more stably prevented from distorting the framework. That is, the strength in the horizontal direction of the telescopic rod 5 by pressing, that is, the strength in the left-right direction in FIG.

  Further, the support cylinder 7 includes a reinforcing base 34 that protrudes in the thickness direction of the reinforcing wall 8. FIG. 11 is a side view of the base frame 1 according to FIG. 8 as viewed from the left front side. As shown in FIG. 11, the reinforcing base 34 is formed so as to protrude outward from the rod frame 29 in the vertical direction of the support cylinder 7, that is, in the back direction of the base frame 1 (right direction in FIG. 11). Is done. In this way, by increasing the diameter of the rising portion of the support cylinder 7 and configuring the support cylinder 7 more firmly, the telescopic rod 5 connected to the support cylinder 7 can be stably supported. The reinforcing base 34 is preferably molded integrally with the support tube 7 from the viewpoint of strength, like the reinforcing wall 8 described above.

  In the example of FIG. 11, the support cylinder 7 has a reinforcement base 34, and the reinforcement base 34 is provided in the entire region of the support cylinder 7 in the vertical direction. Further, the diameter of the support cylinder 7 increases as it approaches the mounting surface 2, that is, the reinforcement base 34 increases the amount of protrusion from the support cylinder 7 toward the bottom, thereby making the support cylinder 7 thicker. In the example of the reinforcing base 34 in FIG. 11, the protruding shape is formed in a gentle slope or curved surface, but the protruding shape and the formation region are not limited to this.

  For example, the support cylinder 7 shown in FIG. 12 has a columnar shape having the same diameter above it. The reinforcing base 34 is formed in a stepped shape so as to protrude in the back direction of the base frame 1 from the middle in the longitudinal direction of the support cylinder 7 to the placement surface 2 side. Further, the shape of the reinforcing base 34 in FIG. 12 is configured such that the diameter of the reinforcing base 34 gradually increases as it approaches the placement surface 2 side.

  On the other hand, in the example of the supporting cylinder 7 shown in FIG. 13, the diameter of the protruding shape of the reinforcing base 34 is substantially constant, that is, the back side of the supporting cylinder 7 protrudes in a stepped manner with the reinforcing base 34. 12 and 13, a single stepped shape is provided and this region is used as the reinforcing base 34. However, the number of the stepped shape may be plural, and the diameter of the reinforcing base 34 may be substantially constant or a structure in which the lower portion is enlarged. . In this way, by projecting the reinforcing base 34 toward the back surface of the base frame 1, the support cylinder 7 and the telescopic rod 5 can be strengthened without providing a projecting portion toward the placement surface 2. That is, the strength of the telescopic rod 5 in the front-rear direction (left-right direction in FIGS. 11 to 13) is increased.

  By adding the reinforcing wall 8 and the reinforcing base 34 to the support cylinder 7, the rod frame 29 can be reinforced in the horizontal direction and the vertical direction, that is, in the front-rear and left-right directions. The three-dimensionally reinforced rod frame 29 has an increased load resistance and can support the load of the heel body 3 and / or the transporter as well as effectively assist in walking. . Moreover, since the eaves 100 can be stabilized and independent, the possibility of tilting when stopping and traveling is significantly reduced.

  The base frame 1 including the mounting surface 2, the support cylinder 7, the reinforcing wall 8, and the reinforcing base 34 is manufactured by integrally forming the whole with a light metal such as plastic or aluminum. Accordingly, the respective parts are connected to each other in the process of molding with plastic or light metal. The base frame 1 can increase the connection strength of the reinforcing wall 8, the reinforcing base 34, the placement surface 2, and the support cylinder 7. However, the base frame 1 of the present invention can also fix each part by structures, such as adhesion | attachment and screwing, after shape | molding each part separately. Further, the material of each member constituting the base frame 1 may be the same or plural, and is appropriately determined in consideration of weight reduction, strength, and the like.

  Further, the shapes of the telescopic rod 5 and the support cylinder 7 are not particularly limited as long as the telescopic rod 5 can be inserted into the hollow of the support cylinder 7. For example, in the bag 100 of FIGS. 8 to 11, the support cylinder 7 is formed in a square cylinder shape corresponding to the prismatic telescopic rod 5. In addition, it can also be a combination of a columnar shape and a cylindrical shape. That is, it is preferable that the outer peripheral shape of the telescopic rod 5 is similar to the hollow inner peripheral shape of the support cylinder 7. The telescopic rod 5 inserted into the support cylinder 7 is fixed to the support cylinder 7 with a set screw. However, the telescopic rod 5 can be inserted into the support cylinder 7 and bonded and fixed, or connected with a fitting structure that does not come off. The structure in which the telescopic rod 5 is connected to the mounting surface 2 with this structure can fix the telescopic rod 5 to the mounting surface 2 with an extremely strong structure.

  As described above, the collar 100 according to the first embodiment is achieved by providing the reinforcing wall 8 and the reinforcing base 34 on the upper side of the mounting surface 2 as reinforcement of the support cylinder 7 and / or the telescopic rod 5. . Accordingly, the reinforcing members of the reinforcing wall 8 and the reinforcing base 34 are not provided on the lower side of the mounting surface 2, so that the mounting position of the caster 6 that is fixed to the bottom surface of the mounting surface 2 is not specified. That is, the caster 6 can be fixed at a desired position. In particular, when the reinforcing member is formed between the support cylinders 7, as shown in FIG. 10, obstacles such as walls can be wiped out in the left-right direction of the placement surface 2. That is, since the spatial restrictions can be reduced in the mounting area of the heel body 3, the choices of the heel body 3 to be mounted are expanded. Furthermore, since the connection position with the support cylinder 7 can be freely set on the upper surface of the mounting surface 2, the separation distance of the support cylinder 7 is adjusted according to the length of the grip 4 that is easy to grip, thereby making the support cylinder 7 ideal. Positioning can be realized.

  FIG. 14A is a plan view from above of the base frame 1, and FIG. 14B is a bottom view of the base frame 1. As shown in FIG. 14, reinforcing ribs 10 extending vertically and horizontally are integrally formed on the bottom surface of the mounting surface 2 with plastic or light metal. The mounting surface 2 can be made strong by the reinforcing ribs 10 while being thinned as a whole. Furthermore, the mounting surface can be made lighter by providing a through-hole penetrating the mounting surface vertically between reinforcing ribs provided vertically and horizontally.

(How to install 鞄 body)
Hereinafter, a method of mounting the bag main body 3 on the base frame 1 will be described. 9 is an upper surface of the mounting surface 2 and is mounted with the main body 3 adjacent to the telescopic rod 5. The bag 100 is structured to be mounted so that the bag body 3 can be attached and detached. However, the bag main body 3 can be fixed to the base frame 1 so that it cannot be detached. Moreover, the magnitude | size and material of the main body 3 are not specifically limited. The bag body 3 in FIG. 9 is manufactured by sewing a flexible sheet.

  First, the base frame 1 will be described. FIG. 15 is a perspective view of the base frame 1. As shown in FIG. 15, the telescopic rod 5 includes a guide cylinder 5B and a pull-out rod 5A inserted into the guide cylinder 5B so as to be able to be inserted and removed. Further, as will be described in detail later, the drawing rod 5A shown in the figure has a two-stage drawing function, and is composed of an upper drawing rod 5Aa and a lower drawing rod 5Ab.

  Further, the base frame 1 in FIG. 15 has a connecting rod 11 that is bridged in a direction (right and left direction in FIG. 15) substantially orthogonal to the extending direction of the telescopic rod 5. This connecting rod 11 has a connecting piece 13 protruding in the placement surface 2 side, that is, in the left front direction of FIG. The connecting rod 11 is provided at the upper end of the guide tube 5B, and the connecting piece 13 is integrally formed of plastic or light metal. The connecting piece 13 is formed in a shape protruding upward on the surface facing the heel body 3 and is inserted into an insertion portion 3B (see FIG. 8) provided in the heel body 3, so that the heel body 3 is Connect so that it does not come off. The insertion portion 3B of the heel body 3 includes a connection gap that opens downward, and the connection piece 13 is inserted therein to be connected to each other.

  Further, the forming position of the connecting piece 13 is not limited to the connecting rod 11. For example, it can be on the telescopic rod 5. For example, another connecting piece 13 b in FIG. 15 is provided on the guide cylinder 5 </ b> B constituting the telescopic rod 5. If it is on the guide cylinder 5B, the distance from the mounting surface 2 to the connecting piece 13b can be shortened, so that even if the height of the main body 3 to be mounted is relatively low, the bottom surface of the main body 3 is The bag main body 3 and the base frame 1 can be mounted stably in a state where the upper surface of the mounting surface 2 is firmly in contact with the upper surface. Moreover, the installation number of the connection pieces 13 and 13b is not specifically limited. For example, if it is a single connection piece, the bag main body 3 and the base frame 1 can be easily attached or detached in a short time. Alternatively, if the plurality of connecting pieces 13 are provided at predetermined intervals in the vertical direction, it is possible to cope with various sizes of the main body 3 and also adjust the connection position with the base frame 1 in the single main body 3. And can.

(Embodiment 2)
Moreover, the connection means of the main body 3 and the base frame 1 is not limited to the above. Another example of the connecting means will be described below as a second embodiment. FIG. 16 is an exploded perspective view of a cage 300 with casters according to the second embodiment. 16 differs from the bag of the first embodiment only in the connection method of the bag body 3 and the base frame 1, and the other structures are the same. Therefore, the same number is attached | subjected about the same structure and description is abbreviate | omitted.

  As shown in FIG. 16, the bag main body 3 according to the second embodiment has an insertion band 40 that opens in the vertical direction. The grip 4 on the base frame 1 side is inserted from below the opening, and the grip 4 is further moved upward, that is, the telescopic rod 5 is inserted through the insertion band 40. Then, as shown in FIG. 17, the heel body 3 and the base frame 1 can be fixed in a state where the heel body 3 is placed on the placement surface 2 of the base frame 1. Further, when the heel body 3 and the base frame 1 are detached, the heel body 3 is raised and the telescopic rod 5 inserted through the insertion band 40 is released. In this way, the hook main body 3 and the base frame 1 can be easily attached and detached by adopting a connection configuration in which a part on the base frame side is inserted into the insertion portion provided on the hook main body 3 side.

  The insertion band 40 is provided on the outermost surface side of the bag main body 3. Although the opening width of the insertion band 40 can be variously changed, it has at least a width through which the rod frame 29 can be inserted, and preferably has some clearance to some extent than the rod frame 29. Thereby, the main body 3 and the base frame 1 can be connected easily and stably. In the example of FIG. 16, a rectangular insertion band 40 is formed on a surface orthogonal to the width direction of the heel body 3, that is, on at least one side of the front and back surfaces of the heel body 3. The insertion band 40 is preferably sewn integrally with the heel body 3 from the viewpoint of ease of manufacturing, but is not limited thereto, and may be formed as a separate member and detachably attached to the heel body 3. Good. Alternatively, in the opening in the vertical direction of the insertion band 40, the upper side may always be opened and the lower side may be appropriately opened and closed with a fastener or the like. Thereby, when using only with the bag main body 3, the lower side of the insertion band 40 is obstruct | occluded and it can utilize as a pocket of the bag main body 3. FIG. Further, the material of the insertion band 40 is not particularly limited, and the design can be improved as the same quality as the heel body 3 or as a separate material. In addition, stretchable materials and materials with added functionality such as friction resistance can be used.

  Furthermore, it is good also as a structure which winds the circumference | surroundings of the base frame 1 with a part of ridge main body 3. FIG. For example, a pair of strips are provided on the basket body 3, and the strips are wound around the telescopic rod 5 or the mounting surface 2 in a state where the basket body 3 is mounted on the mounting surface 2. Furthermore, the both ends of a strip piece are connected, and the bag main body 3 and the base frame 1 are fixed. The connection mechanism between the strip pieces is not particularly limited, and examples thereof include a button, a hook, a hook, a magic tape (registered trademark), a belt, a band, a ring, and a fastener. Further, the connecting means may be singular or various connecting means may be combined.

  Further, the telescopic rod 5 can be stopped at a predetermined position in the telescopic state in the vertical direction, as will be described in detail later. As shown by the arrow in FIG. 15, the base frame 1 is provided with a plurality of stop positions while the drawer rod 5A is inserted into and removed from the guide tube 5B. For example, when the pull-out rod 5A is pushed down, the pull-out rod 5A is housed in the lower guide cylinder 5B and stops at the lowest position. FIG. 18 shows a heel 300 in which the heel body 3 and the base frame 1 are connected by the connecting means according to the second embodiment, and the telescopic rod 5 is further lowered. As shown in FIG. 18, in a posture in which the telescopic rod 5 is stopped at the lowest position, the base frame 1 is reduced in size and stored along the heel body 3. That is, the overall size of the heel 100 can be made substantially the same as that of the heel body 3, and as a result, the entire heel 300 can be lifted and transported by placing the handle 46 of the heel body 3 on the shoulder or arm. That is, the base frame 1 can be stored and transported integrally with the bag main body 3, and the bag 300 can be moved even when the caster 6 is not used. This is convenient when the kite 300 is lifted from the road surface and transported in an environment where it is difficult to use the casters 6, such as a road surface having a level difference. In particular, as shown in FIG. 18, by passing the handle 46 on the side adjacent to the telescopic rod 5 out of the pair of handles 46 of the heel body 3 from the inside to the outside between the grip 4 and the connecting rod 11. Since the handle 46 can support the grip 4 so as to be wound from the bottom to the top, it is easy to carry stably.

  Further, as shown in FIGS. 8 to 9 or 11, when the telescopic rod 5 is extended and the grip 4 is pulled up, the grip 4 is decentered from one side fixed to the mounting surface 2 toward the center. It is curved to let you. As shown in the figure, when the telescopic rod 5 is fixed to the right side of the placement surface 2, the center of the placement surface 2 means the center in the left-right direction. 9 has a telescopic rod 5 fixed to the right side of the mounting surface 2, so that when the telescopic rod 5 is pulled up, the grip 4 is decentered from the right side to the left side of the mounting surface 2. The telescopic 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 decentered in a direction approaching the center from the side portion of the mounting surface 2. In the state where the telescopic rod 5 is pulled up, the grip 4 is not necessarily positioned at the center of the placement surface 2. This is because even if the grip 4 is not completely at the center, the grip 4 can be pushed and moved forward so as not to bend the heel 100. The position of the lifted grip 4 is, for example, 15 to 80, assuming that one end face of the mounting surface 2 to which the telescopic rod 5 is fixed is a reference 0 point and the opposite end face is 100 in the figure. % Position, preferably 20 to 60%, more preferably 20 to 50%.

(Embodiment 3)
Further, FIG. 19 is a side view of the cage-attached scissors 400 according to the third embodiment, and when the telescopic rod 5 is extended and the grip 4 is pulled up, from one side fixed to the mounting surface 2 to the center. The telescopic rod 5 is tilted and fixed to the mounting surface 2 so that the grip 4 is eccentric. 19 has a telescopic rod 5 fixed to the right side of the mounting surface 2, so that when the telescopic rod 5 is pulled up, the grip 4 is decentered from the right side to the left side of the mounting surface 2. The telescopic rod 5 is inclined. The tilting telescopic rod 5 does not necessarily need to be positioned at the center of the mounting surface 2 in the state in which the grip 4 is pulled up, similarly to the curved telescopic rod 5. This is because even if the grip 4 is not completely at the center, the grip 4 can be pushed to move forward so as not to bend.

  Further, although not shown in the drawing, the hook can be tilted and fixed to one side of the mounting surface by tilting the curved telescopic rod, and the grip can be lifted to be decentered from one side of the mounting surface toward the center. This ridge can increase the radius of curvature to bend and make the inclination angle close to a right angle, and pull up the grip to approach the center of the mounting surface. This is because the lifted grip can be decentered from the side of the mounting surface to the center by both inclining and bending.

  In the bag of the above embodiment, two telescopic rods 5 are fixed to both ends on one side of the mounting surface 2. As described above, the structure in which the telescopic rod 5 is disposed on one side of the mounting surface 2 allows the heel body 3 to be disposed on almost the entire top surface of the mounting surface 2, so There is a feature that can widen. However, the scissors of the present invention are not specified as a structure in which the telescopic rods are arranged at both ends on one side of the placement surface. For example, the telescopic rod 5 can be disposed on one side of the mounting surface at a position eccentric to the center.

  When the telescopic rod 5 is in a contracted state, in other words, when the grip 4 is pushed down 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 6 to the top surface of the grip 4 is about 50 cm. However, the distance between the bottom surface of the caster 6 and the top surface of the grip 4 is preferably 30 to 80 cm, more preferably 35 to 70 cm at the position where the telescopic rod 5 is contracted to make the grip 4 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 6 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.

  As shown in FIG. 15, the telescopic rod 5 includes a guide cylinder 5B fixed to the mounting surface 2 so as to extend in the vertical direction, and a two-stage drawer rod inserted so as to be able to be taken in and out of the guide cylinder 5B. 5A, and the grip 4 is fixed to the upper end of the upper extraction rod 5Aa. The two-stage drawing rod 5A is inserted so that the upper drawing rod 5Aa is thinner than the lower drawing rod 5Ab so that the upper drawing rod 5Aa can be taken in and out of the lower drawing 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 guide cylinder 5B and the extraction rod 5A can be metal cylinders having different thicknesses. The guide tube and the extraction rod can be manufactured by molding plastic or light metal into a rectangular tube shape. The telescopic rod shown in the figure has a structure that can be expanded and contracted in two stages. However, the telescopic rod can be configured as a one-stage expandable structure or a structure that can be expanded and contracted in three stages or more.

  The scissors shown in the above figures have two telescopic rods 5 fixed to at least a partial region on one side of the mounting surface 2 and the grip 4 is connected to the upper ends of the two telescopic rods 5. Specifically, the two telescopic rods 5 are fixed at both corners on one side of the mounting surface 2 or closer to the center side from both ends.

  Further, the two telescopic rods 5 connect the upper ends of the guide cylinders 5 </ b> B with connecting rods 11. The guide cylinder 5 </ b> B has a lower end inserted into the support cylinder 7 of the mounting surface 2 and fixed, and an upper end portion is connected by a connecting rod 11. Thus, the structure which connects the upper end of the guide cylinder 5B with the connecting rod 11 can reinforce the two telescopic rods 5, and can stand more stably. An insertion gap 14 is provided between the connecting rod 11 and the grip 4 that is lowered as shown in FIG. This is to make it easier to grasp the lowered grip 4. The grip 4 shown in the figure is made of plastic or light metal as a whole into a U shape, and the bent portions at both ends are connected to the extraction rod 5A to provide an insertion gap 14.

  The stopper can use any mechanism that can stop the expansion and contraction of the telescopic rod 5. An example of the stopper is shown in FIGS. The telescopic rod 5 shown in these drawings has a structure in which the two-stage drawing rod 5A can be expanded and contracted, and thus has two stoppers 15 at the top and bottom. 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 portion 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 elastically protruding 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 protruding pins 16 and 36 are arranged on the extraction rod 5A so as to protrude 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 tube 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 projected through the through holes and the telescopic rod 5 can be stopped reliably. . This is particularly safe when the telescopic rod 5 is used in place of a cane, 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 a feature that the telescopic rod 5 can be prevented from being pulled out unexpectedly when holding the grip 4 and lifting the entire bag. 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 even when the grip 4 is in the raised position and in 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. Provided in position. 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. 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. Furthermore, the upper drawer rod can be provided with a plurality of locking portions in the middle of the lower drawer rod, and the upper drawer rod pulled up to the middle can be stopped at a plurality of lifting positions. The telescopic rod can be selected in an optimum position by moving the grip position up and down little by little.

  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. Furthermore, as shown in FIG. 21, 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.

A pin 22A is provided. When the rotary piece 22 is pressed by the drive rod 21 and rotates, the tip of the pin 22A is brought into contact with the protruding portions 16A provided on both sides of the protruding pin 16, and the protruding pin 16 is rotated by the rotating pin 22A. Press to forcibly retract. When the pressing of the drive rod 21 is released, the protruding pin 16 is no longer pressed by the pin 22A of the rotating piece 22, and is elastically pushed out by the elastic member 19 to rotate the rotating piece 22 to the original posture.

  In the first release mechanism 18 described above, when the push button 20 is pressed, the drive rod 21 is pushed down, and the rotating piece 22 disposed at the lower end of the drive rod 21 is rotated. The rotating piece 22 that rotates rotates the protruding pin 16 at the tip of the pin 22 </ b> A in a direction in which the protruding pin 16 is pulled out, and pulls the protruding pin 16 out of the locking portion 17. In this state, the first stopper 15A is released, and the upper drawing rod 5Aa can move up and down in the lower drawing rod 5Ab. When the push button 20 is released, the projecting pin 16 is pressed by the elastic member 19 so that it can project toward the lower extraction rod 5Ab.

  The first stopper 15 </ b> A pushes the push button 20 of the first release mechanism 18 provided on the grip 4 to forcibly retract the protruding pin 16 to release the locked state. In this state, the upper extraction rod 5Aa is pulled up or lowered. The upper drawing rod 5Aa into which the protruding pin 16 is drawn moves up and down in the lower drawing rod 5Ab. When the grip 4 is adjusted to a predetermined height after the push button 20 is released, the protruding pin 16 is guided to the locking portion 17, the expansion and contraction of the upper extraction rod 5Aa is stopped, and the grip 4 is raised and lowered. Stopped.

The guide cap 35 has an insertion hole 35A on the upper surface so that the insertion rod 31 can be inserted. The rotating piece 32 is bent in an L shape as a whole, and one end is connected to the guide cap 35 via the rotation shaft 33 and protrudes toward the protruding pin 36 on both sides of the other end. A pin 32A is provided. When the rotating piece 32 is pressed by the insertion rod 31 and rotates, the tip of the pin 32A is brought into contact with the protruding portions 36A provided on both sides of the protruding pin 36, and the protruding pin 36 is moved by the rotating pin 32A. Press to forcibly retract. When the pressing of the insertion rod 31 is released, the protruding pin 36 is no longer pressed by the pin 32A of the rotating piece 32, and is elastically pushed out by the elastic member 39 to rotate the rotating piece 32 to the original posture.

  In the second release mechanism 38 described above, when the upper extraction rod 5Aa is pushed to the deepest part of the lower extraction rod 5Ab, the insertion rod 31 is inserted into the insertion hole 35A of the guide cap 35, and the lower end of the lower extraction rod 5Ab. The rotating piece 32 disposed on is rotated. The rotating piece 32 that rotates rotates the protruding pin 36 at the tip of the pin 32 </ b> A in the direction in which the protruding pin 36 is pulled out, and pulls the protruding pin 36 out of the locking portion 37. In this state, the second stopper 15B is released, and the lower extraction rod 5Ab can move up and down in the guide tube 5B. At this time, the protruding pin 16 of the upper stopper 15 </ b> Aa is inserted into the locking portion 17 provided at the lowest position of the lower extraction rod 5 </ b> Ab, and the insertion rod 31 is held in the state of being inserted into the insertion hole 35 </ b> A of the guide cap 35. Has been. For this reason, the protruding pin 36 is held in a state of being moved in the pulling direction by the rotating piece 32. In this state, the upper extraction rod 5Aa and the lower extraction rod 5Ab are connected in a contracted state, and the upper extraction rod 5Aa and the lower extraction rod 5Ab are integrally connected to each other inside the guide cylinder 5B. Move up and down.

  Further, when the upper drawing rod 5Aa and the lower drawing rod 5Ab that are integrally connected are inserted into the guide cylinder 5B most deeply, the protruding pin 16 of the first stopper 15A is a locking portion provided inside the guide cylinder 5B. 30 is inserted. In this state, the contraction of the telescopic rod 5 is stopped, and the grip 4 is stopped in the state where it is lowered most. When releasing the locking state between the protruding pin 16 and the locking portion 30, the push button 20 of the first release mechanism 18 is pressed to pull out the protruding pin 16 from the locking portion 30. In this state, the lower extraction rod 5Ab can move up and down in the guide tube 5B.

  Further, when stopping the pulling out of the lower pulling rod 5Ab, the push button 20 of the first release mechanism 18 is pushed to forcibly pull the protruding pin 16 to release the first stopper 15A, and the upper pulling rod 5Aa is moved to the lower step. Pull out from the extraction rod 5Ab. At this time, the insertion rod 31 is pulled out from the insertion hole 35 </ b> A of the guide cap 35, and the protruding pin 36 is protruded by the elastic member 39. In this state, the lower pull-out rod 5Ab is pulled out, the protruding pin 36 is inserted into the locking portion 37 provided at the upper end of the guide cylinder 5B, and the pull-out of the lower pull-out rod 5Ab is stopped.

  The stopper 15 having the above-described structure can stop the telescopic rod 5 in which the extraction rod 5A is expanded and contracted in two stages at a predetermined position. However, the bag of the present invention does not specify the stopper as the above structure. The stopper can be any mechanism that can stop the telescopic rod at a predetermined position.

(Embodiment 4)
In addition, the cradle platform 102 with casters is provided with a reinforcing rib protruding on the lower surface of the mounting plate 9. The reinforcing rib is integrally formed with a lateral reinforcing rib 112A that extends in the lateral direction on the lower surface of the mounting plate 9 and protrudes downward. Further, the lateral reinforcing rib 112A projects as a reinforcing projecting portion 108 by projecting a region located below the support cylinder 7 downward. The reinforcing protrusion 108 reinforces the structure of the base frame 1 more firmly. A caster-equipped scissors 500 having a reinforcing protrusion 108 is referred to as a fourth embodiment, and a detailed description thereof will be given below. However, members having the same functions as those in the first to third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, in order to make the features of the members according to Embodiment 4 stand out and be displayed, the illustration of other members may be omitted.

  FIG. 23 is a partially enlarged perspective view of a cage 500 with casters according to the fourth embodiment, and shows a perspective view of the base frame 1 observed from the back side of the cage 500. 24 and 25 are perspective views of the caster-equipped cage 500 viewed from the bottom surface side, that is, a partially enlarged view showing the back side of the mounting surface 2 of FIG. 24 is a perspective view from the rear side of the bottom surface 2A, and FIG. 25 is a perspective view from the front side of the bottom surface 2A. In FIG. 25, casters are indicated by dotted lines, and in FIG. 24, the casters are not shown. Moreover, in this specification, the designation | designated concerning a direction is defined as follows. That is, with reference to the corner portion of the mounting plate 9 connecting the support cylinder 7, the short side of the rectangular mounting plate 9 is in the x-axis direction, the long side of the mounting plate 9 is in the y-axis direction, and the axial direction of the support cylinder 7 The directions substantially coincident with the normal direction of the mounting plate 9 are referred to as the z-axis direction (upward direction in FIG. 23). Further, the long side of the mounting plate 9 is referred to as “longitudinal” and the short side is referred to as “lateral”.

  As with the first embodiment, the caster-equipped scissors 500 according to the fourth embodiment includes a scissors main body 3 and a base frame 1 that can carry the scissors main body 3. As shown in FIG. 23, the base frame 1 has a platform 102 on which the heel body 3 is detachably mounted. The mounting table 102 has a flat plate-like plate 9, and the support cylinder 7 is connected in a posture extending substantially upward from both ends on one side of the plate plate 9. Moreover, the upper surface of the mounting plate 9 can be used as the mounting surface 2, and the bag main body 3 can be placed on the mounting surface 2 in contact therewith. The mounting plate 9 further includes a bottom surface 2A facing the mounting surface 2 and a side surface 2B on the outer periphery of the mounting plate 9.

  The mounting table 102 in FIG. 23 is provided with reinforcing ribs on the bottom surface side on the outer peripheral portion of the mounting plate 9. The reinforcing rib provided on the mounting plate 9 is provided so as to protrude below the mounting plate 9 so as to be substantially perpendicular to the mounting surface 2, and does not protrude above the mounting surface 2. Thereby, the mounting area | region of the collar main body 3 can be ensured widely, without the reinforcement rib of the mounting plate 9 projecting on a mounting surface. Further, the reinforcing ribs around the mounting plate 9 having a rectangular overall shape are a horizontal reinforcing rib 112A provided parallel to the short side of the mounting plate 9, and a vertical reinforcing rib provided parallel to the long side of the mounting plate 9. 122.

  The lateral reinforcing rib 112A has a reinforcing protrusion 108 (cross-hatched portion in FIG. 23) that protrudes the lower edge portion further downward. The reinforcing protrusion 108 is integrally formed with the lateral reinforcing rib 112A. Further, the reinforcing protrusion 108 is provided so as to be positioned below the connecting portion between the mounting plate 9 and the support cylinder 7. 23 protrudes downward so as to be located at the connecting portion between the mounting plate 9 and the support cylinder 7 and is integrally formed with the lateral reinforcing rib 112A. More specifically, the reinforcing protrusion 108 is provided along the edge of the joint surface 103 (the chain line portion in FIG. 23) where the support cylinder 7 and the mounting surface 2 are joined. The reinforcing protrusion 108 is disposed in a posture substantially orthogonal to the joint surface 103. This reinforcing protrusion 108 improves the bending strength in the vertical plane of the lateral reinforcing rib 112A and also improves the bending strength of the mounting plate 9 so that the support cylinder 7 fixed to the upper surface does not tilt in the vertical plane. Secure firmly and firmly. In the example of FIG. 23, the reinforcing protrusions 108 are arranged in a part of the lateral reinforcing ribs 112A, specifically, only the connecting portion between the support cylinder 7 and the mounting surface 2 is arranged. As a result, the lateral reinforcing rib 112A having the reinforcing protrusion 108 protrudes further downward than the other regions around the connection region between the mounting plate 9 and the support cylinder 7, and the mounting plate 9 and the support 7 and the like 7 Can be reinforced in a concentrated manner. In addition, the reinforcing protrusion 108 can further increase the strength of the mounting base 102 by increasing the overall length in the lateral direction. On the other hand, reducing the overall lateral length of the reinforcing protrusion 108 can reduce the weight of the entire mounting base 102. I can plan. The reinforcing protrusion 108 can have a total length in the length direction of the lateral reinforcing rib of 3 cm to 10 cm, preferably 5 cm to 8 cm. If the total length of the reinforcing protrusion 108 in the x-axis direction is in the above range, it is preferable because both the strength and light weight of the mounting table 102 can be achieved. Further, the reinforcing protrusions can be provided not only on the horizontal reinforcing ribs but also on the vertical reinforcing ribs. A reinforcing protrusion provided on the vertical reinforcing rib is also provided below the support cylinder to reinforce the mounting plate connecting the support cylinder.

  The outer surface of the reinforcing protrusion 108 is substantially flush with the outer surface of the side surface 2B of the mounting plate 9 and the lateral reinforcing rib 112A. By making the lateral reinforcing ribs 112 </ b> A and the reinforcing projecting portions 108 the same surface from the side surface 2 </ b> B, the base frame 1 can be reinforced without the lateral reinforcing ribs 112 </ b> A having the reinforcing projecting portions 108 protruding in the longitudinal direction of the mounting plate 9. In addition, the design is excellent. In addition, the reinforcing protrusion 108 can be added to the mounting plate 9 of the first to third embodiments or other forms of the base frame as needed, and the base frame 1 can be reinforced as necessary.

  It is preferable that the mounting base 102 is integrally formed of the same member such as plastic with the mounting plate 9, the lateral reinforcing rib 112 </ b> A, and the entire reinforcing protrusion 108. This is because, by integrally forming the platform 102 with the members constituting the platform 102 as the same member, the strength of the base frame 1 can be increased, and the number of parts can be reduced to simplify the manufacturing. . The reinforcing protrusion 108 is formed into a shape that increases the downward protrusion amount of the lateral reinforcing rib 112A in a region close to the rising portion of the support cylinder 7 from the mounting surface 2, and the mounting surface 2 and the support cylinder 7. It is provided in the connection part. 23 is an outer periphery of the joint surface 103 between the support cylinder 7 and the mounting surface 2 and is a rising portion of the mounting surface 2 and the support cylinder 7 in a plan view from the side surface 2B. The amount of protrusion is maximized below the junction point D where the and are joined at a substantially right angle. This structure can most effectively reinforce the connecting portion between the mounting plate 9 and the support tube 7 with the lateral reinforcing rib 112A having the reinforcing protrusion 108.

  In addition, the lateral reinforcing rib 112A having the reinforcing protruding portion 108 increases the protruding amount H of the lateral reinforcing rib 112A around the rising portion of the support cylinder 7 that is easily stressed on the mounting surface 2, In the region, the protruding amount H of the lateral reinforcing rib 112A may be reduced. That is, as shown in FIG. 24, it is preferable that the protrusion amount m of the reinforcing protrusion 108 is the largest in the joint region 120 between the mounting surface 2 and the support cylinder 7. For example, in the example of FIG. 23, the mounting surface D and the rising portion of the support cylinder 7 are joined at a substantially right angle in a plan view from the side surface 2B, and the bottom surface 2A is lowered from the joining point D. The vertical line S has a raised shape so as to substantially coincide with the apex T of the curve of the reinforcing protrusion 108. That is, the height of the upper and lower sides of the lateral reinforcing rib 112A is the outer periphery of the joint surface 103 where the support tube 7 and the mounting surface 2 are joined, and at the rising portion of the support tube 7 that is substantially perpendicular to the mounting surface 2. Is the largest. Further, it is preferable that the protruding amount of the reinforcing protruding portion 108 is larger on the junction point D side than the corner portion of the mounting table 102. Thereby, the thickness of the platform 102 in the region where stress is likely to concentrate can be increased and effectively reinforced. However, the apex T of the bulge does not necessarily need to coincide with the perpendicular S, and a sufficient reinforcing effect can be obtained even if there is some displacement.

  Thus, by providing the reinforcing protrusion 108 on the lateral reinforcing rib 112A, the structure of the base frame 1 can be further strengthened. This is due to the following reason. When a pressing force or a force for tilting the support cylinder 7 is applied in the downward direction of the support cylinder 7, bending stress acts on the mounting plate 9. The lateral reinforcing rib 112A having the reinforcing protrusions 108 reinforces the base frame 1 from the lower surface to improve the bending strength and prevent the base frame 1 from being deformed or damaged. In particular, by providing the reinforcing protrusion 108 in the vicinity of the rising portion of the support cylinder 7, the connecting portion 120 where stress tends to concentrate is effectively reinforced. Therefore, this structure can also improve the impact resistance against an extremely large impact acting on the support cylinder 7 instantaneously.

  Further, in addition to the reinforcement from the bottom surface 2A side by the lateral reinforcing rib 112A provided with the reinforcing protrusion 108, the reinforcing wall 8 and the reinforcing base 34 (see FIG. 8) described in the first to third embodiments may be provided. Good. As a result, the joining region 120 between the mounting surface 2 and the support cylinder 7 can be three-dimensionally reinforced from the bottom, side, and rear three directions, so that the strength of the frame of the base frame 1 can be more effectively increased. .

  Further, it is preferable that the reinforcing protrusion 108 has a shape in which the central portion is raised and gradually lowered toward both sides thereof. This is because the bending strength by the reinforcing protrusion 108 can be improved and the impact resistance can be enhanced. Further, the strength of the base frame 1 can be effectively increased by increasing the protrusion amount H from the placement surface 2 to the lower end of the reinforcement protrusion 108 by the reinforcement protrusion 108. However, if the amount of protrusion H below the lateral reinforcing rib 112A having the reinforcing protrusion 108 is excessively large, the reinforcing protrusion 108 comes into contact with the caster 6 when the caster-equipped rivet 500 is used. There is a risk of hindering smooth movement. In order to avoid this problem, the height of the reinforcing protrusion 108 is limited so that the caster 6 does not contact.

  Specifically, FIG. 26 is a partial rear view of the bag with a caster 500 according to the fourth embodiment, and FIG. 27 is a partial side view. The lower end of the reinforcing protrusion 108 is positioned above the upper end of the wheel 114 in the rotation area of the swing caster 6 as shown in FIGS. More preferably, the protrusion amount m of the reinforcing protrusion 108 is limited so as to provide a gap d between the bottom surface 109 of the reinforcing protrusion 108 and the uppermost surface of the wheel 114 in the rotation region of the caster 6. As a result, even when a load is applied in the gravitational direction of the kite and the platform 102 sinks downward and the distance between the upper end of the wheel 114 and the lower end of the reinforcing protruding portion 108 becomes narrow, the reinforcing protruding portion 108 Contact with the caster 6 can be avoided. That is, a smooth swinging motion of the caster 6 can always be maintained. The clearance d may be set to an optimum value depending on the material and play of the fixed portion of the caster 6, the pivot shaft, and the yoke, and is about 2 mm in a state where the heel body is not placed and the heel is self-supporting. However, the gap d can be 1 mm to 4 mm, preferably 1 mm to 3 mm.

  The reinforcing protrusion 108 is not particularly limited as long as it does not contact the caster 6, and may be various shapes such as an arc shape, a rectangular shape such as a rectangle, a trapezoid, and a parallelogram, a semicircular shape, and a convex shape. Further, as shown by a broken line in FIG. 27, the main area of the reinforcing protrusion 108 is increased by projecting downward to such an extent that it does not contact the ground, and only the contact area is cut out by turning the swing caster 6. It is good. In the fourth embodiment, as shown in FIG. 27, in the lateral direction (x-axis direction) of the reinforcing protrusion 108, the protrusion amount m of the reinforcing protrusion 108 is increased in the region below the joining region 120, and the reinforcing protrusion The overall protrusion amount H downward of the lateral reinforcing rib 112 </ b> A having 108 is increased. Further, the protrusion m is made smaller toward both ends of the reinforcing protrusion 108 so that the reinforcing protrusion 108 has an arc shape. Then, at the corner portion of the platform 2 including the support cylinder 7, the downward protrusion amount m of the reinforcing protrusion 108 is reduced, and the wheel 114 of the caster 6 is rotated so as to straddle the bottom surface 109 of the reinforcing protrusion 108. It has a structure that can be done. That is, since the lateral reinforcing rib 112 </ b> A including the reinforcing protrusion 108 does not come into contact with the caster 6 at the mounting position of the caster 6, the operation of the caster 6 is not hindered. That is, the reinforcing protrusion 108 has a unique shape so that the protruding amount H of the lateral reinforcing rib 112A in the joining region 120 is larger than the protruding amount H of the lateral reinforcing rib 112A at the corner of the platform 102 to which the casters 6 are connected. By doing so, the reinforcing area can be sufficiently earned while maintaining the free rotation of the caster 6.

  Further, the number of the lateral reinforcing ribs 112A may be single, but it is preferable to provide a plurality of them from the viewpoint of strength. As shown in FIGS. 24 and 25, separately from the lateral reinforcing ribs 112 </ b> A provided around the mounting plate 9, lateral reinforcing ribs may be further provided inside the mounting plate 9. The inner lateral reinforcing rib 112B is arranged in parallel with the surrounding lateral reinforcing rib 112A and from the center of the bottom surface 2A. Further, it is preferable that the inner lateral reinforcing rib 112B is positioned below the connecting portion between the mounting plate 9 and the support tube 7 similarly to the surrounding lateral reinforcing rib 112A. In the example shown in the drawing, the peripheral lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B are installed on the bottom surface along the edge of the connecting portion between the mounting plate 9 and the support cylinder 7. The peripheral lateral reinforcing ribs 112A and the inner lateral reinforcing ribs 112B are provided substantially in parallel so as to sandwich the casters 6 attached to the corners of the mounting surface 2. By providing the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B on the bottom surface 2A located below the supporting cylinder 7, the connecting portion between the mounting plate 9 and the supporting cylinder 7 can be strongly reinforced from the bottom surface side. In particular, the bending strength of the mounting plate 9 against the horizontal tilt of the support cylinder 7 can be effectively improved. Moreover, the shape of the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B may be the same or may be separate. In the illustrated example, the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B have the same shape. If the shape of the lateral reinforcing ribs 112A and 112B is the same, the forming process can be facilitated and the manufacturing process can be simplified. Alternatively, the lateral reinforcing ribs 112A and 112B have different shapes, for example, lateral reinforcing ribs arranged in an area where the rotation of the caster 6 is not obstructed. The shape may be changed. Or you may make the external shape of a horizontal reinforcement rib small, and reduce the total weight of a collar.

  Further, the lateral reinforcing rib 112B on the inner side of the figure is composed of one member. The inner lateral reinforcing rib 112B may have a shape having a reinforcing protrusion 108 having a shape protruding downward with respect to the members constituting the mounting table 102, similarly to the surrounding horizontal reinforcing rib 112A. For example, the reinforcing protrusions 108 may be integrally formed with the reinforcing ribs 10 that are already disposed. In the lateral reinforcing rib 112B in the drawing, a region (cross hatched portion) that protrudes further downward (in the direction approaching the ground) than the wall of the reinforcing rib 10 is referred to as a reinforcing protruding portion 108 for convenience.

  Further, reinforcing ribs 10 are provided on the bottom surface 2A side of the mounting plate 9 so as to cross each other. As shown in FIGS. 24 and 25, the mounting table 102 has reinforcing ribs 110 at the corners surrounded by the reinforcing ribs 10 and the vertical reinforcing ribs 122 that are orthogonal to the four corners of the bottom surface 2 </ b> A. The support cylinder 7 is provided on the mounting surface 2 of the mounting plate 9 on the opposite side of the bottom surface 2A surrounded by the reinforcing ribs 110 at the corners as shown in FIG. Furthermore, as shown in FIG. 25, the caster 6 is fixed to the partition section partitioned by the reinforcing ribs 110 at the corners. In other words, the caster 6 and the support cylinder 7 are partition portions formed by the reinforcing ribs 110 at the corners, and are arranged vertically via the mounting plate 9. Further, two rows of horizontal reinforcing ribs 112A and 112B having the reinforcing protrusions 108 are provided in contact with the side surfaces of the reinforcing ribs 110 at the corners, so that the connection between the reinforcing ribs 110 at the corners and the bottom surface 2A can be strengthened. . As a result, the support cylinder 7 and the mounting plate 7 can be effectively reinforced from the bottom side.

  Further, the mounting table 102 is provided with two rows of lateral reinforcing ribs, that is, a peripheral lateral reinforcing rib 112A and an inner lateral reinforcing rib 112B in parallel to each other at the connecting portion of the support cylinder 7. Two rows of bottom reinforcing ribs 208 are integrally formed on the lower surface of the mounting plate 9 between the two rows of horizontal reinforcing ribs 112A and 112B so as to protrude downward. 24 and 25 are provided with two rows of bottom reinforcing ribs 208, the bottom reinforcing ribs 208 can be arranged in one row, or can be arranged in three or more rows. 24 and 25, the mounting frame 110A is provided between the two rows of horizontal reinforcing ribs 112A below the support cylinder 7, and the bottom reinforcing rib 208 is provided on the connecting rib 110A. Are connected. This mounting table is provided by integrally forming two rows of horizontal reinforcing ribs, connecting ribs 110A, and bottom reinforcing ribs 208 with plastic.

  Specifically, the connecting rib 110 </ b> A is a part of the corner reinforcing rib 110 and is integrally formed with the bottom surface 2 </ b> A along the edge of the connecting portion between the support cylinder 7 and the mounting plate 9. Both ends of the connecting rib 110A are connected substantially orthogonally to the two rows of lateral reinforcing ribs 112A and 112B, that is, the connecting rib 110A is arranged in parallel to the longitudinal direction of the mounting plate 9. The bottom reinforcing rib 208 is formed integrally with the mounting plate 9 and the connecting rib 110A by connecting one end of the bottom reinforcing rib 208 to the connecting rib 110A. Further, the mounting base 102 in the figure is provided with two rows of bottom reinforcing ribs 208 at equal intervals. Further, the bottom reinforcing rib 208 is disposed in a posture that is parallel to the lateral reinforcing ribs 112A and 112B. The length of the bottom reinforcing rib 208 is not particularly limited, but is about 4 cm. However, if the length of the bottom reinforcing rib 208 is 3 cm to 5 cm, it is preferable to balance manufacturing simplicity, strength, and weight reduction. The bottom reinforcing rib 208 in FIGS. 24 and 25 is provided so that one end thereof is connected to the connecting rib 110A. However, a connecting rib (not shown) is provided at both ends of the bottom reinforcing rib 208 to connect to the connecting rib 110A. You can also. The number of the bottom reinforcing ribs 208 arranged may be single or plural, but it is preferable that the number of the bottom reinforcing ribs 208 be plural because the support cylinder 7 and the mounting table 102 can be firmly stabilized. By providing the bottom reinforcing rib 208, the impact resistance and bending strength in the lateral direction of the mounting surface 2 can be enhanced. In particular, it is preferable to dispose on the lower side of the support cylinder 7 because the stress that tends to occur in the continuous region between the support cylinder 7 and the mounting plate 9 can be relaxed and a larger load can be supported. The bottom reinforcing rib 208 in the figure is lower than the lateral reinforcing ribs 112A and 112B, and the width thereof is wider than that of the lateral reinforcing rib to improve the strength. However, the height of the bottom reinforcing rib 208 may be substantially the same as the height of the lateral reinforcing ribs 112A and 112B. Further, the bottom reinforcing rib 208 can be raised to improve the reinforcing effect, but it can be prevented from contacting the caster 6 as a height that does not contact the caster 6. Alternatively, like the lateral reinforcing ribs 112A and 112B, the portion of the caster 6 excluding the region where the wheel rotates can be raised so as to project outward, and the vertical width can be widened to enhance the reinforcing effect.

  By installing the lateral reinforcing ribs 112A and 112B and the bottom reinforcing rib 208 in this way, the joining region 120 can be reinforced from multiple directions, and as a result, the strength of the base frame can be effectively increased. Specifically, the lateral reinforcing ribs 112A and 112B and the bottom reinforcing ribs 208 are arranged substantially in parallel in a plurality of rows, and at the corners of the mounting table 102, which is the joining region 120 between the support cylinder 7 and the mounting surface 2. The skeleton can be made dense and sturdy. In addition, the base frame can be reinforced and the overall weight of the base frame can be reduced by the structure in which the plurality of rows of the lateral reinforcing ribs 112A and 112B and the bottom reinforcing rib 208 are provided apart. The thickness of the lateral reinforcing ribs 112A and 112B is 3 mm. However, this thickness can be 2 mm to 4 mm. The thickness of the bottom reinforcing rib 208 is about 5 mm. However, the thickness of the bottom reinforcing rib 208 can be 3 mm to 10 mm. If the lateral reinforcing ribs 112A and 112B and the bottom reinforcing rib 208 are too thin, the strength may be reduced. If the lateral reinforcing ribs 112A and 112B are too thin, the cost of the members and the total weight of the base frame may be increased.

  By the way, the cage 500 can have various sizes of the rectangular mounting plate 9. For example, FIG. 28, FIG. 29, and FIG. 30 are bottom views of the mounting table 102 showing the mounting plates 200a, 200b, and 200c of various sizes. In these bottom views, the reinforcing protrusions 108 and the bottom reinforcing ribs 208 in the surrounding lateral reinforcing ribs 112A and the inner lateral reinforcing ribs 112B and the bottom reinforcing ribs 208 are clearly shown with cross hatching. In addition, in the examples of FIGS. 28 to 30, three types of placement surfaces are shown, and these three types have the same length in the longitudinal direction (y-axis direction) and the lateral direction (x-axis direction). Only the side length is different. That is, the side in the horizontal direction is short in FIG. 28, and gradually increases in FIGS. Specifically, the length of the side in the longitudinal direction × lateral direction is 261 mm × 150 mm in FIG. 28, 261 mm × 180 mm in FIG. 29, and 261 mm × 210 mm in FIG. However, the shape of the mounting surface is not limited to the above-mentioned size, and it goes without saying that various ridges can be mounted so as to be detachable as being wider or narrower than the described size.

  Further, as shown in FIGS. 28 to 30, the mounting table 102 includes the reinforcing ribs 110 at the corners of the mounting plate 9 at the corners of the mounting plate 9 at both ends of the short side of the bottom surface 2 </ b> A. The corner reinforcing rib 110 is one end of the short side of the mounting plate 9, and is a rear corner that is provided with the reinforcing rib 10 in four directions along the edge of the connection region between the mounting plate 9 and the support tube 7. It has a reinforcing rib 111A and a reinforcing rib 111B at the front corner provided at the other end of the short side. The reinforcing ribs 111 </ b> B at the front corners are provided in a quadrangular shape with the horizontal reinforcing ribs 112 </ b> A and 112 </ b> B in the horizontal direction, the vertical reinforcing ribs 122 and the reinforcing rib 10 in the vertical direction. The reinforcing rib 111A at the rear corner can reinforce the connection between the mounting plate 9 and the support cylinder 7 from the bottom side. Further, the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B are arranged substantially in parallel with the outer surface of the reinforcing rib 111A at the rear corner. By arranging the reinforcing rib 111A at the rear corner between the two parallel rows of horizontal reinforcing ribs 112A and 112B, the reinforcing rib 11A at the rear corner is further reinforced to connect the support cylinder 7 and the mounting plate 9 Can be further reinforced on the bottom side.

  Further, FIG. 31 is a bottom view of the mounting table 102 and shows a partially enlarged view of the bottom surface 2A. The front casters 6 are preferably fixed at both ends of the long side of the bottom surface 2A, and the casters are preferably separated as much as possible. This is because the heel 500 can stand by itself without tilting.

  One end of the surrounding lateral reinforcing rib 112A covers the side surface of the reinforcing rib 111A at the rear corner, and the other end constitutes a reinforcing rib 111B at the front corner. Therefore, the reinforcing rib 111A at the rear corner is positioned on the inner side (right side in FIG. 31) by the thickness w of the lateral reinforcing rib 112A. There is a deviation in the longitudinal direction (y-axis direction) between the positions of the reinforcing ribs 111A at the rear corners located at the corners of the platform 102 and the reinforcing ribs 111B at the front corners. The inner lateral reinforcing rib 112B is provided in an inclined manner corresponding to a shift in the arrangement of the reinforcing rib 111A at the rear corner and the reinforcing rib 111B at the front corner. As shown in FIG. 31, one end of the inner lateral reinforcing rib 112B covers and contacts the side surface of the reinforcing rib 111A at the rear corner, and inclines to the left as shown in FIG. 31, while the other end is the front corner. One side of the reinforcing rib 111 </ b> B is configured and further connected to the vertical reinforcing rib 122. Further, in the example of FIG. 31, the total weight of the mounting table 102 is reduced by not providing the reinforcing rib 10 in the longitudinal direction between the reinforcing rib 111A at the rear corner and the reinforcing rib 111B at the front corner.

  On the other hand, the platform 102 shown in FIG. 32 includes a bridging rib 118 positioned in parallel with the connecting rib 110A in addition to the structure of the platform 102 shown in FIG. The bridging rib 118 is provided between the reinforcing rib 111A at the rear corner and the reinforcing rib 111B at the front corner, and is integrally formed with 2A on the bottom surface. The bridging rib 118 is substantially orthogonal to the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B, and bridges these lateral reinforcing ribs 112A and 112B. Both ends of the bridging rib 118 can be connected to the surrounding lateral reinforcing rib 112A and the inner lateral reinforcing rib 112B, respectively, so that the connection strength between the lateral reinforcing ribs 112A and 112B and the bottom surface 2A can be increased. The inner lateral reinforcing rib 112 </ b> B may intersect with the bridging rib 118. 32 has one end in contact with the side surface of the reinforcing rib 111A at the rear corner, and is connected perpendicularly to the bridging rib 118 from the one end to the bridging rib 118 in a straight line. Further, the inner lateral reinforcing rib 112B is curved to the left from the connecting region with the bridging rib 118 toward the other end, constitutes one side of the reinforcing rib 111B at the front corner, and is further connected to the vertical reinforcing rib 122. .

  In addition, the members such as the mounting plate 9, the reinforcing ribs 10, the reinforcing protrusions 108, the lateral reinforcing ribs 112 </ b> A and 112 </ b> B, the bottom reinforcing ribs 208, and the bridging ribs 118 that are members constituting the mounting base 102 are separate members. May be connected to each other. Alternatively, at least two or more members can be integrally formed of plastic to increase the strength. However, it is also possible to increase the strength by integrally molding with a light metal such as aluminum instead of plastic.

  Moreover, the connection method of the caster fixed to the reinforcement rib 110 of a corner part is not specifically limited. In the example of FIG. 25, the reinforcing rib 110 at the corner includes a recess that opens to one side with the bottom surface 2A as the lowest surface. And it connects so that the upper part of this recessed part may be obstruct | occluded with the flat caster base 115 (refer FIG. 26). Specifically, the reinforcing ribs 110 at the corners have bosses 113 at the four corners as shown in FIG. The caster base 115 is a plate surface having substantially the same shape as the rectangular shape of the reinforcing ribs 110 at the corners, and is a position that substantially overlaps the arrangement position of the bosses 113 when covering the concave portions of the reinforcing ribs 110 at the corners. Has a through hole. With the caster base 115 covering the upper surface of the reinforcing rib 110 at the corner, a fastening member such as a screw is fitted into the boss 113 through the through hole, and the caster base 115 is fixed to the mounting base 102. Further, by connecting the caster 6 to the caster base 115 or by connecting the caster 6 to the caster base 115 in advance, the caster 6 is moved to the bottom surface 2A side of the mounting base 102 via the caster base 115. Can be linked.

  Thus, on the bottom side of the mounting plate 9, along the side surface 2B or so as to fill the gaps of the reinforcing rib structure originally provided, the reinforcing protruding portion and the lateral reinforcing rib provided with this reinforcing protruding portion, Alternatively, by providing a reinforcing member such as a bottom reinforcing rib or a bridging rib, without restricting the placement position of a member located above the placement surface 2, such as a placement space of the heel body or a support cylinder The strength of the mounting table 102 can be increased. On the mounting plate 9, a reinforcing wall and a reinforcing base are provided on the long side to which the support cylinder 7 is fixed. Further, by arranging members fixed on the upper side of the mounting plate 9 such as the support cylinder 7, the reinforcing wall, and the reinforcing base, the members are arranged on one side of the mounting plate 9, thereby providing a barrier on the other side of the mounting surface 2. In addition, it is possible to reinforce the mounting table 102 while ensuring a wide mounting area for the bag main body 3. In this way, the cage-attached cage can be stably and independently supported by the structure in which the top and bottom of the mounting plate 9 and the periphery of the support cylinder 7 are reinforced intensively. Further, since the telescopic rods can be arranged at both ends of the mounting surface 2, the distance between the telescopic rods can be sufficiently increased to lengthen the gripping area. This makes it easy to grasp the grip and easily controls the direction of movement of the bag.
