Description

  The present invention relates to a handle for manually pushing a silver car and a handle for pulling a carry bag.

  A silver car is a wheelbarrow for assisting walking when an elderly person walks on the road or takes a walk. There are various types of silver cars, but basically there are four wheels on the front and rear of a frame made of metal pipes, so that you can drive stably by pushing the handle. The frame cannot accommodate small parcels and is attached with a cloth bag.

  On the other hand, a carry bag is a bag for storing and carrying luggage when traveling. Therefore, the carry bag has a handle that expands and contracts, and a wheel is attached to the lower end on the back side of the bag. Therefore, it is usually possible to carry the product by rolling it with the handle. However, when going up and down the stairs, it is possible to hold the handle and lift it up with the hand. The carry bag is made of metal, resin, or cloth, and has a substantially rectangular parallelepiped shape.

The “silver car” according to Japanese Patent Application Laid-Open No. 11-43046 is easy to fold and expand and is excellent in stability in an upright state.
That is, the push rod and the upper end of the rear leg are connected to each other by an armrest lever so as to be pivotable.

“Carrying bag with hanger function” according to JP 2004-73534 A
By adding a hanger function, it can be carried together with a jacket or handbag.
From the upper part of the transport handle part, which is provided at the upper part of the main body and is fixedly or slidably connected to the main frame, and has a central part sandwiched between the parallel vertical parts of the downward U-shape. It is set as the structure containing the hanger protrusion part which can be made to protrude toward the outer side of the said parallel perpendicular | vertical part. The hanger protrusions may be housed in a gripping hand or in a cylindrical part parallel to the gripping hand with a pair of swing bars. Further, it may be a pair of rods or plates that rotate approximately 90 degrees from a posture along the parallel vertical portion of the transport handle and protrude outward.

In addition to these, various silver cars and carry bags are known. Silver cars and carry bags have handles. That is, it is possible to hold the handle provided at the upper end of the handle to push the silver car and to hold the handle and pull the carry bag. The handle is slidable so that the height of the handle can be adjusted. The conventional handle sliding mechanism is stepped, and sometimes a problem arises that even if it is adjusted, it does not match the body shape.
"Silver Car" according to Japanese Patent Application Laid-Open No. 11-43046 "Wheelbarrow" according to Japanese Patent Application Laid-Open No. 11-115763 "Carry bag with hanger function" according to Japanese Patent Application Laid-Open No. 2004-73534

  Thus, the conventional silver car and carry bag handle have the above problems. The problem to be solved by the present invention is this problem, and provides a handle for a silver car and a carry bag that can be adjusted steplessly by sliding up and down.

  The handle of the silver car and carry bag according to the present invention has a structure in which the handle height at the upper end can be adjusted steplessly by sliding in the vertical direction, and is clamped and fixed at an arbitrary height. By the way, the handle is attached to a guide case fixed to the silver car main body and the carry bag main body and guided to slide, and a multi-node body in which a plurality of links are connected via a shaft as a stepless clamping means. A multi-node body is bent in a zigzag shape, and a mandrel is engaged with shafts arranged in two rows in parallel. The lower end of the mandrel is fixed to the guide case and extends upward.

  One end of the multinode body is fixed, and the other end is a free end, and is clamped by pulling a mandrel meshing with a plurality of shafts from the base end toward the end. This is because each shaft moves together with the mandrel to the tip side by friction, and as a result, the mandrel is clamped because the distance between the axes arranged in two rows is reduced. On the other hand, when the mandrel is moved from the distal end side toward the proximal end, the distance between the axes arranged in two rows is increased, and the mandrel can freely slide.

  In the present invention, this multi-node body is mounted in pairs in the vertical position, and a mandrel is inserted between the axes of the multi-node body bent in a zigzag shape. And the clamp release member which compresses a free tip is provided, and a clamp is cancelled | released by operating a clamp release operation part. The zigzag chain is generally provided on the handle side, but it can be attached to the guide case side and the mandrel can be provided on the handle side.

  The handle of the silver car and the carry bag according to the present invention can slide in the vertical direction to change the height of the handle provided at the upper end. Moreover, since the handle slide can be adjusted steplessly, the height adjustment of the handle is stepless, so that the handle can be finely adjusted to the most easily held height.

  The handle can slide along the guide case, but a plurality of links can be connected via a shaft, and the mandrel can be clamped by a shaft bent in a zigzag manner. By attaching the multi-node body composed of the plurality of links in a pair in the vertical direction, the handle can be slid in the vertical direction and clamped at an arbitrary position (height).

  FIG. 1 is an embodiment showing one embodiment of a silver car provided with a handle according to the present invention, and the silver car has a function as a carry bag. In the figure, 1 is a bag, 2a and 2b are front wheels, 3a and 3b are rear wheels, and 4 is a handle. The silver car shown in the figure shows a state in which the steering wheel 4 can be lifted and the vehicle can be driven. The steering wheel 4 can be slid up and down, and the upper end of the steering wheel 4 can be held with both hands 5a and 5b. Is extended to both sides. The handles 5a and 5b can be expanded and contracted so that their lengths can be adjusted.

  The front wheels 2a and 2b are attached to lower ends on both sides of the front face of the bag 1, and are supported so that the direction thereof can be changed. The rear wheels 3a and 3b are attached not to the bag 1 but to the front ends (lower ends) of the legs 6a and 6b that are attached to the back side of the bag 1 and extend obliquely rearward. Therefore, the distance between the front wheels 2a and 2b and the rear wheels 3a and 3b is increased, and a stable running as a silver car can be performed.

  A conventional general silver car has a frame made of metal pipe, a front wheel and a rear wheel are attached to the frame, and a bag or a box for putting small luggage is attached to the frame. On the other hand, in the silver car shown in the embodiment, the monocoque bag made of metal or resin itself functions as a frame without using a frame in which metal pipes are assembled, and the front wheels 2a and 2b and the rear wheels are made to function as a frame. 3a and 3b are attached. However, if the front wheels 2a and 2b and the rear wheels 3a and 3b are attached to the front and rear lower ends of the bag 1, the distance between the front and rear wheels 2 and 3 is small and unstable, so the rear wheels 3a and 3b It is attached to the front ends of legs 6a and 6b extending obliquely.

  FIG. 2 shows a case where the chair 7 attached to the back of the bag is pulled out. A chair 7 is attached to the silver car of the present invention, and the chair 7 is stored on the back of the bag 1. Then, it can be pulled out as shown in FIG. 2 when necessary, and can sit down and rest temporarily using this chair 7. The silver car has legs 6a and 6b extending obliquely rearward, and the rear wheels 3a and 3b are attached to the front ends of the legs, and at the same time, the chair 7 is also supported by the legs 6a and 6b to be stabilized. I can do it.

  FIG. 3 shows the mounting structure of the chair 7 attached to the leg 6a. Of course, it is attached to the other leg 6b with the same structure, but the shaft 10 protrudes horizontally inside the leg 6a, and a link 11 is connected to the shaft 10. Two ribs 12 a and 12 b are provided on the lower surface on one side of the chair 7, and the other end of the link 11 is connected to the rib 12 a via a shaft 13.

  Further, a guide groove 14 is provided in the longitudinal direction inside the leg 6a, and a shaft 15 attached to the rib 12b is loosely fitted in the guide groove 14. Accordingly, when a load is applied to the chair 7 from above, the shaft 15 provided on the rib 12b is positioned at the lower end of the guide groove 14, so that the link 11 does not rotate. Therefore, it is possible to sit on the chair 7 and take a rest. When the chair 7 is not required, if the shaft 15 of the rib 12b is slid upward along the guide groove 14, the chair 7 is parallel to the leg 6a, and if the leg 6a is folded, the chair 7 is also It is housed on the back side of the bag 1 together with the legs 6a. The shaft 16 in the figure is an attachment shaft for the legs 6a.

  FIG. 4 shows a state in which the lid of the bag 1 is opened. The bag 1 is provided with a lid that can be opened and closed, and can be opened to be inclined to the surface side as shown in FIG. If the lid is opened, the bag 1 can be opened to store the luggage in the internal space 9 and can function as a carry bag. Of course, when used as a carry bag, the chair 7 can be folded and the legs 6a and 6b can be folded and stored, the front wheels 2a and 2b can be lifted, and the rear wheels 3a and 3b can be pulled with the road surface rolling.

  In FIG. 5, the handle 4 is reduced and the handles 5a and 5b are positioned at the upper end of the bag 1, and both legs 6a and 6b are folded and stored in a groove formed on the back surface of the bag. Therefore, the figure shows the case where it is used as a carry bag. The carry bag can be lifted by holding the handle. 6 shows the back side of FIG. 5, both legs 6 a and 6 b are accommodated in the grooves, and the rear wheels 3 a and 3 b are located at the lower end on the back side of the bag 1.

  Further, the grips 5a and 5b are provided with an auxiliary grip portion 8. When the bag 1 is lifted in the state shown in FIGS. 5 and 6, the auxiliary grip portion 8 can be used. The auxiliary grip 8 is located between the two handles 5a and 5b and on the front side of the bag 1. Both the handles 5a and 5b are provided on the back side of the bag 1 and in substantially the same plane as the handle 4 that slides up and down. If the bag 1 is lifted at the positions of the handles 5a and 5b, the bag 1 Since the center of gravity of the bag is on the front side, the lifted bag 1 is tilted and the lower end of the back is in contact with the body. Therefore, it becomes difficult to walk with the bag 1.

  The auxiliary grip 8 positioned on the front side is positioned in a plane passing through the center of gravity of the bag 1, and the bag 1 lifted by gripping the auxiliary grip 8 does not tilt and hits the body. Absent. Therefore, it is easy to hold the bag 1 and to walk easily. When used as a carry bag, generally, the rear wheels 3a and 3b can roll on the road surface. However, when going up and down the stairs, the bag 1 must be lifted, and the bag 1 is stabilized without tilting by having the auxiliary grip portion 8.

  FIG. 7 shows the back side of the bag 1, but a handle 4 is attached to the back side of the bag 1. FIG. 8 is a specific example showing a cross section of the vertical slide mechanism of the handle 4 according to the present invention, and the handle 4 shown in FIG. The handle 4 is formed of a pipe having a rectangular cross section, and the handle 4 is fitted and attached to an outer case 17 serving as a guide, and can slide up and down along the outer case 17.

  Further, the lower end of the outer case 17 is pivotally supported and can swing in the front-rear direction. A mandrel 18 is fixed to the lower end of the outer case 17, and the mandrel 18 extends upward. A multi-node body (chain) bent in a zigzag manner is disposed inside the handle 4 to clamp the mandrel 18. The zigzag chain is attached to the vertical position at a predetermined interval, and the mandrel 18 fixed to the outer case 17 is clamped to prevent the handle 4 from sliding in the vertical direction. That is, the mandrel 18 is inserted through the through hole formed in the zigzag chain.

  FIG. 9 is a schematic view showing the slide / clamp mechanism of the handle 4 according to the present invention. The handle 4 fitted to the outer case 17 can be slid up and down, and the handle 4 is clamped at a predetermined position, The handles 5a and 5b can be kept at an appropriate height. Accordingly, the upper zigzag chain 19 and the lower zigzag chain 20 are engaged with a mandrel 18 extending upward from the lower end of the outer case 17, whereby the handle 4 is clamped to a predetermined height.

  The upper zigzag chain 19 and the lower zigzag chain 20 are configured by connecting a plurality of links 29, 29... Via shafts 30, 30. , 30... Can be bent in a zigzag shape as shown in FIG. The shafts 30, 30... Of the bent upper zigzag chain 19 and the lower zigzag chain 20 are arranged in two rows at predetermined intervals to form through holes. The mandrel 18 is inserted through the through hole.

  Accordingly, the mandrel 18 is clamped by being sandwiched between the shafts 30, 30... Of the upper zigzag chain 19 and the lower zigzag chain 20. An upper end shaft 30 of the upper zigzag chain 19 is attached to the handle 4 side as a fixed end 21, and a lower end shaft 30 of the lower zigzag chain 20 is attached to the handle 4 side as a fixed end 22. Therefore, when the handle 4 slides upward, the fixed end 21 of the upper zigzag chain 19 rises together with the handle 4, but since the upper zigzag chain 19 is stretched, each shaft engages with the mandrel 18 and is clamped. Is done. Therefore, if the free end 27 located at the lower end of the upper zigzag chain 19 is lifted and compressed, the shafts 30, 30... Are separated from the mandrel 18 and the handle 4 can slide upward.

In this case, the lower zigzag chain 20 is compressed by the fixed end 22 provided at the lower end as the handle 4 is raised, and the shafts 30, 30... Are separated from the mandrel without any problem. Conversely, when sliding the handle 4 downward,
The fixed end 22 of the lower zigzag chain 20 descends together with the handle 4. However, since the lower zigzag chain 20 is stretched, the shafts 30, 30. Therefore, if the free end 28 located at the upper end of the lower zigzag chain 20 is pressed down and compressed, the shafts 30, 30... Are separated from the mandrel 18 and the handle 4 can slide downward. I can do it.

  In this case, the upper zigzag chain 19 is compressed by lowering the handle 4 and lowering the fixed end 21 provided at the upper end, and the shafts 30, 30... Are separated from the mandrel without any problem. Therefore, a clamp release plate 23 is attached to the slide / clamp mechanism of FIG. 9, and the clamps of the upper zigzag chain 19 and the lower zigzag chain 20 are released by raising and lowering the clamp / release plate 23.

The clamp release plate 23 is disposed between the free end 27 of the upper zigzag chain 19 and the free end 28 of the lower zigzag chain 20, and when the clamp release plate 23 is raised, the free end 27 is lifted and the upper zigzag chain is lifted. 19 clamps are released. Therefore, the handle 4 can slide upward. Conversely, if the clamp release plate 23 is lowered, the free end 28 is pushed down, and the clamp of the lower zigzag chain 20 is released. Therefore, the handle 4 can slide downward.
By the way, the upper zigzag chain 19 and the lower zigzag chain 20 act so that the spring force is urged and stretched. That is, the shafts 30, 30... Can always contact the mandrel 18. In particular, the free end 28 of the lower zigzag chain 20 is lowered by its own weight so that the shafts 30, 30.

  FIG. 10 shows a specific example of a clamping mechanism using a zigzag chain. In FIG. 10, 19 denotes an upper zigzag chain, 20 denotes a lower zigzag chain, and the upper end of the upper zigzag chain 19 is connected to a fixed end 21. The lower zigzag chain 20 is similarly fixed to the handle side by forming a fixed end 22 at the lower end. The upper and lower zigzag chains 19, 20 are formed by connecting a plurality of links 29, 29... By shafts 30, 30... And bending them into a sawtooth shape to form a zigzag shape. A through hole is formed by bending into a shape, and a mandrel 18 is inserted through this hole.

  Therefore, as described with reference to FIG. 9, when the handle 4 is slid upward and extended, the shafts 30, 30... Of the upper zigzag chain 19 having the fixed end 21 at the upper end are connected to the mandrel 18. Engage with and clamp. When the handle 4 is slid downward to be contracted, the shafts 30, 30... Of the lower zigzag chain 20 having the fixed end 22 at the lower end engage with the mandrel 18 and are clamped. In this way, the vertical slide of the handle 4 is clamped by the upper zigzag chain 19 and the lower zigzag chain 20.

  Therefore, in order to slide the handle 4 up and down, the upper zigzag chain 19 and the lower zigzag chain 20 must be clamped. In the figure, reference numeral 23 denotes a clamp release plate. The clamp release plate 23 extends upward and the upper end is fixed to the buckle 24, and the buckle 24 is attached to the lower end of the connecting pipe 25. The upper end of the connection pipe 25 extends to the upper end portion of the handle 4 and is connected to the clamp release operation portion 26.

  FIG. 11 shows a handle 5 attached to the upper end of the handle 4, and a clamp release operation portion 26 is attached to the handle 5. The clamp release operation part 26 in the figure is in a lifted state, and if the clamp release operation part 26 is lifted, the connecting pipe 25 rises and the clamp release plate 23 also rises. As a result, the free end 27 of the upper zigzag chain 19 is lifted by the clamp release plate 23, and the shafts 30, 30... Of the upper zigzag chain 19 are disengaged from the mandrel 18, and the handle 4 is moved upward. Can be slid. That is, the handle 4 can be extended.

  On the contrary, if the clamp release operation part 26 is pushed down, the connecting pipe 25 is lowered, and the free end 28 of the lower zigzag chain 20 is pushed down by the lowering of the clamp release plate 23 connected to the lower end of the connecting pipe 25. It is done. As a result, the shafts 30, 30... Of the lower zigzag chain 20 are disengaged from the mandrel 18, and the handle 4 can be slid downward. That is, the handle 4 can be shortened. Therefore, if the clamp release operation unit 26 is disposed at an intermediate position, the handle 4 cannot be raised or lowered. In order to keep the clamp release operation portion 26 at an intermediate position, a balance is maintained by a coil spring arranged in an upper / lower pair. That is, unless the clamp release operation unit 26 is operated, the clamp release operation unit 26 is kept balanced at the intermediate position so that the handle 4 does not move up and down.

  In this way, the handle 4 can slide up and down to expand and contract, and the height of the handle 5 provided at the upper end of the handle can be adjusted steplessly depending on the body shape of the elderly. In the embodiment shown in FIGS. 9 and 10, the upper zigzag chain 19 and the lower zigzag chain 20 are attached to the handle side, and the mandrel 18 is provided on the outer case side. A reverse arrangement is also possible.

  That is, the upper zigzag chain 19 and the lower zigzag chain 20 can be attached to the outer case side serving as a guide for the handle 4, and the mandrel 18 can be provided on the handle side. In this case, since the clamp release operation part 26 of the clamp release plate 23 cannot be provided in the handle part, for example, it can be provided in the upper end part of the outer case.

  On the other hand, the upper zigzag chain 19 and the lower zigzag chain 20 are multi-node bodies in which a plurality of links 29, 29... Are flexibly connected via shafts 30, 30. Any form will be irrelevant. The most common zigzag chain is constructed by connecting both ends of shafts 30, 30... With links 29, 29..., Like a roller chain often used for power transmission of motorcycles. I can do it. Of course, unlike the power transmission roller chain, the zigzag chain of the present invention does not require bushings or rollers.

  Moreover, it is set as the multinode body which provided link 29,29 ... in the center part of axis | shaft 30,30 ..., and in this case, axis | shaft 30,30 ... is to the both sides of link 20,29 .... It extends. Accordingly, two mandrels 18 are provided on both sides of the links 29, 29... And the two mandrels 18, 18 can be sandwiched and clamped by the shafts 30, 30.

  FIG. 12 shows a specific example in which the slide clamp device of the handle 4 is removed from the handle 4, and is attached to the inside of the handle 4 of FIG. In the figure, reference numeral 19 denotes an upper zigzag chain, 20 denotes a lower zigzag chain, 18 denotes a mandrel, and a fixing plate 33 is provided on one side of the upper and lower zigzag chains 19, 20. The upper member 31 and the lower member 32 are connected and fixed, and are attached to the handle 4.

  The fixed ends 21 and 22 of the zigzag chains 19 and 20 are provided above and below the fixed plate 33. The clamp release plate 23 is provided on the opposite side of the fixed plate 33 across the upper and lower zigzag chains 19 and 20, and extends upward to be connected to the block 24. A connecting pipe 25 extends upward from the block 24 and is connected to the unlocking operation unit 26. The mandrel 18 fixed to the lower end of the outer case extends upward through the lower member 32, the lower zigzag chain 20, the upper zigzag chain 19, the upper member 31, the block 24, and the connecting pipe 25. By the way, the slide / clamp device shown in FIG. 12 is manufactured independently of the handle 4 and can be attached to the inside of the handle 4, so that the manufacturing man-hour of the slide handle is reduced.
