`[CLAIM 2]
`A telescoping tube as described in claim 1, comprising:
`a stopper mechanism for preventing the first pipe from
`being extended further when in a state wherein the second
`pipe has been extended from the first pipe by a prescribed
`length, where the locking hole is formed at a position that
`faces the locking member when in a state wherein the
`second pipe is extended to a prescribed length.
`[Detailed Explanation of the Invention]
`[0001]
`[Field of Technology of the Present Invention]
`The present invention relates to a telescoping tube to
`which a load is applied in the axial direction during use,
`such as, for example, in a cane, a walking stick, a tripod, or
`the like.
`[0002]
`[Prior Art]
`Telescoping tubes, with adjustable lengths, are used in,
`for example, canes, walking sticks, tripods, and the like. A
`telescoping tube is structured through a plurality of pipes,
`made from aluminum alloys or composite materials that are
`made from carbon fibers, or the like, of mutually differing
`widths, that are connected together sequentially. That is, a
`smaller-diameter second pipe is inserted into the inside of a
`larger-diameter first pipe, and both pipes are secured
`together at a desired length through a clamping mechanism.
`[0003]
`Conventionally a variety of different clamping
`mechanisms have been proposed and commercialized.
`Typically this type of clamping mechanism has a built-in
`friction member, where a structure is used wherein the
`friction member is pressed against an outer peripheral
`surface of the second pipe through a lever or a tightening
`ring, so as to secure the first pipe and the second pipe at a
`desired length.
`
`[0004]
`[Problem Solved by the Present Invention]
`In a clamping mechanism that uses a conventional
`friction member, when a large load is applied to the
`telescoping tube in the axial direction thereof, in excess of
`the frictional force when locked, the friction member will
`slip along the outer peripheral surface of the tube, and the
`telescoping tube will become short.
`[0005]
`Because of this, in a telescoping tube for supporting a
`body, such as, for example, a cane or a walking stick, the
`telescoping tube may collapse unexpectedly when a large
`load is applied in the axial direction, and in this point there
`is room for improvement.
`[0006]
`Given this, the object of the present invention is to
`provide a telescoping tube that is equipped with a clamping
`mechanism that can withstand a large load in the axial
`direction.
`[0007]
`[Means for Solving the Problem]
`The telescoping tube according to the present invention
`comprises a first pipe, a second pipe that is inserted into the
`first pipe, and a clamping mechanism. The clamping
`mechanism has a base member that is secured to the first
`pipe, a pressing member that is provided on the base
`member, a lever that is provided with cam means, a locking
`member, and a locking hole. The tip end face of the
`pressing member faces the outer peripheral surface of the
`second pipe, and is able to move in the direction to press on
`the outer peripheral surface of the second pipe.
`[0008]
`The lever is able to rotate between a locking position and
`an unlocking position, where the pressing member is
`pressed toward the second pipe when the lever is in the
`locking position. When the lever is in the unlocking
`position, the pressing force against the second pipe is
`released. When, in a state wherein the second pipe extends
`a prescribed length from the first pipe, the lever is operated
`to the locking position, the locking member is pressed by
`the lever, and the tip end portion of the locking member is
`inserted into the locking hole.
`[0009]
`In a preferred aspect of the present invention, a stopper
`mechanism is provided for preventing the second pipe from
`being extended by more than a prescribed length from the
`first pipe, where the locking hole is formed in the position
`that faces the locking member in the state wherein the
`position of the second pipe is constrained by the stopper
`mechanism.
`[0010]
`[Embodiments of the Invention]
`A first embodiment according to the present invention
`will be explained below in reference to FIG. 1 through FIG.
`5. In the telescoping tube 10 depicted in FIG. 1, the
`structure is such that pipes 11 and 12, made from, for
`example, an aluminum alloy, having a plurality of widths,
`are inserted sequentially, from the wider to the narrower,
`and each of the pipes 11 and 12 can be connected together
`through a clamping mechanism 13.
`[0011]

`

`

`Japanese Unexamined Patent Application Publication 2003-130017 (P2003-130017A)
`(3)
`
`The second pipe 12 is inserted into the first pipe 11. As
`means to prevent the pipes 11 and 12 from rotating in
`respect to each other, groove portions 15 and 16, which fit
`together, are formed in the pipes 11 and 12, along the axial
`directions thereof. While FIG. 1 shows only two pipes 11
`and 12, clamping mechanisms 13 may be provided at each
`of the connecting portions between the pipes in a
`telescoping tube made of three or more pipes.
`[0012]
`The clamping mechanism 13 will be explained below.
`The clamping mechanism 13 comprises a base member 20
`that is secured to an end portion 11a of the first pipe 11. A
`lever 22 is attached to a shaft 21 that is provided on the
`base member 20, as depicted in FIG. 2. The lever 22 can
`rotate, on the shaft 21, between the unlocking position
`depicted in FIG. 2 and the locking position depicted in FIG.
`3.
`[0013]
`The lever 22 has a cam face 25 that functions as the cam
`means. The cam face 25 comprises a first cam face 25a and
`a second cam face 25b, which are structured from arc­
`shaped curved surfaces. The distance R1 from the center C
`of the shaft 21 to the first cam face 25a is less than the
`distance R2 from the center C of the shaft 21 to the second
`cam face 25b.
`[0014]
`A pressing member 30 is provided between the cam face
`25 and the second pipe 12. The tip end face 31 of the
`pressing member 30 faces the outer peripheral surface 12b
`of the second pipe 12. The tip end face 31 fits into the
`groove portion 16 of the second pipe 12. A recessed portion
`32, formed on the outer surface side of the pressing
`member 30, faces the cam face 25.
`[0015]
`The pressing member 30 is moved toward the outer
`peripheral surface 12b of the second pipe 12 through being
`pressed by the second cam face 25b when the lever 22 is
`operated from the unlocking position, depicted in FIG. 2, to
`the locking position, depicted in FIG. 3. When the lever 22
`is operated to the unlocking position depicted in FIG. 2, the
`first cam face 25a and the pressing member 30 will face
`each other, releasing the pressing on the pressing member
`30.
`[0016]
`A locking member 40 is provided on a retainer 39 that is
`attached to the base member 20. The locking member 40 is
`able to move in the radial direction of the first pipe 11. The
`tip end portion 41 of the locking member 40 protrudes,
`toward the second pipe 12, through a hole 42 that is formed
`in the first pipe 11.
`[0017]
`A locking hole 45 is formed in a position of the second
`pipe 12 corresponding to the tip end portion 41 of the
`locking member 40. The locking hole 45 is an opening that
`is at a position into which the tip end portion 41 of the
`locking member 40 can be inserted when in a state wherein
`the second pipe 12 is extended by a prescribed length from
`the first pipe 11.
`[0018]
`The locking member 40 is able to move in the radial
`direction of the pipes 11 and 12 from a position wherein the
`tip end portion 41 is out of the locking hole 45, as depicted
`
`in FIG. 2 and FIG. 4, and a position wherein the tip end
`portion 41 is inserted into the locking hole 45, as depicted
`in FIG. 3 and FIG. 5. The locking member 40 is biased, by
`a spring 46, in the direction for removal from the locking
`hole 45, and when the lever 22 is operated to the locking
`position, depicted in FIG. 3, the locking member 40 is
`pressed toward the pipe 12 by the inner surface 22a of the
`lever 22, so that the tip end portion 41 of the locking
`member 40 will enter into the locking hole 45.
`[0019]
`The telescoping tube 10 is equipped with a stopper
`mechanism 50 for preventing the second pipe 12 from
`extending further when the second pipe 12 has been
`extended to a prescribed length from the first pipe 11. The
`stopper mechanism 50 is structured from an intermediate
`ring 51 that functions as a friction reducing member that is
`secured to the inner surface side of the base member 20,
`and a retaining member 52 that is installed at an end
`portion 12a of the second pipe 12. The retaining member
`52 is attached to the end portion 12a of the pipe 12 through
`insertion of a protruding portion 52a into a hole 53 that is
`formed in the pipe 12.
`[0020]
`As illustrated in FIG. 5, when the second pipe 12 is at
`maximum extension in respect to the first pipe 11, the
`retaining member 52 will contact the end face 51a of the
`intermediate ring 51, preventing the second pipe 12 from
`being extended any further. The tip end portion 41 of the
`locking member 40 will be able to enter into the locking
`hole 45 through alignment of the tip end portion 41 of the
`locking member 40 with the position of the locking hole 45
`in the state wherein the relative positioning of the second
`pipe 12 in the axial direction is constrained by the stopper
`mechanism 50 in this way.
`[0021]
`The operation of the clamping mechanism 13 described
`above will be explained next. When the lever 22 is in the
`unlocking position, as depicted in FIG. 2 and FIG. 4, the
`cam face 25 will substantially not press on the pressing
`member 30. Moreover, because the tip end portion 41 of
`the locking member 40 is withdrawn from the locking hole
`45, the second pipe 12 is able to move in the axial direction
`in respect to the first pipe 11.
`[0022]
`If the lever 22 is rotated in the direction of the locking
`position, depicted in FIG. 3, when the second pipe 12 is
`extended to the desired length, the pressing member 30 will
`be pressed by the second cam face 25b toward the second
`pipe 12. In this case, the second pipe 12 is secured by the
`frictional force between the tip end face 31 of the pressing
`member 30 and the outer peripheral surface 12b of the
`second pipe 12.
`[0023]
`When the second pipe 12 is maximally extended from
`the first pipe 11, further extension of the second pipe 12 is
`prevented through the retaining member 52 contacting the
`end face 51a of the intermediate ring 51, as depicted in FIG.
`5. In this case, the tip end portion 41 of the locking member
`40 will face the locking hole 45.
`[0024]
`When, in this state, the lever 22 is operated to the
`locking position, as depicted in FIG. 3, the pressing
`

`

`(4)
`
`member 30 will be pressed by the second cam face 25b of
`the lever 22 toward the second pipe 12, and the tip end
`portion 41 of the locking member 40 will move into the
`locking hole 45 through the locking member 40 being
`pressed toward the second pipe 12 by the inner surface 22a
`of the lever 22.
`[0025]
`In this way, the fitting of the locking member 40 and the
`locking hole 45 produces a state wherein the first pipe 11
`and the second pipe 12 are secured in the axial direction. In
`this case, in addition to the frictional force between the
`pressing member 30 and the outer peripheral surface 12b of
`the second pipe 12, there will also be the strength of the
`locking member 40 in the shearing direction through the
`locking member 40 entering into the locking hole 45. This
`enables the pipes 11 and 12 to be clamped reliably, without
`any slackening occurring in the clamping mechanism 13.
`[0026]
`This telescoping tube 10 is able to withstand a large
`applied force F in the axial direction. Because of this, when
`there is the possibility of a large force being applied in the
`axial direction, as in a walking stick or a cane, this makes it
`possible to avoid a failure, such as collapsing of the
`telescoping tube 10 when the force is applied, thereby
`enabling safe use.
`[0027]
`FIG. 6 and FIG. 7 depict a clamping mechanism 13'
`according to a second embodiment according to the present
`invention. Note that the same reference symbols as in the
`first embodiment are applied to the same positions as with
`the clamping mechanism 13 in the first embodiment, and
`explanations thereof are omitted.
`[0028]
`The clamping mechanism 13' according to the second
`embodiment comprises a pair of pressing pieces 60 and 61
`in the interior of the second pipe 12. A spring 62 is
`provided between the pressing pieces 60 and 61. The tip
`end portion 60a of one of the pressing pieces 60 can enter
`into the locking hole 45 that is formed in the second pipe
`12. The tip end portion 61a of the other pressing piece 61 is
`inserted into a hole 63 that is formed in the second pipe 12.
`The locking member 40' is inserted into a hole 64 that is
`formed in the base member 20 and a hole 42 that is formed
`in the first pipe 11, and is able to move in the radial
`direction of the pipes 11 and 12.
`[0029]
`The spring 62 biases one pressing piece 60 in the
`direction of the locking member 40', and also biases the
`other pressing piece 61 toward the hole 63. The tip end
`portions 60a and 61a of the pressing pieces 60 and 61 have
`arc-shaped curved surfaces that are raised toward the
`outside, or tapered surfaces. A recessed surface 66 is
`formed on the tip end portion 65 of the locking member 40',
`and the tip end portion 60a of the pressing piece 60
`contacts the recessed surface 66.
`[0030]
`When the second pipe 12 is pulled out all the way to the
`limit from the first pipe 11, the retaining member 52, as
`depicted in FIG. 6, contacts the end face 51a of the
`intermediate ring 51, preventing the second pipe 12 from
`extending any further. In this case, the tip end portion 65 of
`the locking member 40' faces the locking hole 45.
`
`[0031]
`When, in this state, the lever 22 is operated to the
`locking position, the tip end portion 65 of the locking
`member 40' enters into the locking hole 45 through the
`locking member 40' being pressed by the inner surface 22a
`of the lever 22. In this case, the pressing piece 60 is pressed
`by the locking member 40', to be pressed into the inside of
`the pipe 12.
`[0032]
`As described above, in a state wherein the position of the
`second pipe 12 in the axial direction is constrained by the
`stopper mechanism 50, the locking member 40' and the
`locking hole 45 can fit together, making it possible to
`withstand a large load F that is applied to the pipes 11 and
`12 in the axial direction, in the same manner as in the first
`embodiment.
`[0033]
`On the other hand, when the lever 22 is operated to the
`unlocking position, the locking member 40' is moved to the
`position indicated by the double-dotted line in FIG. 6
`through the elastic force of the spring 62. Because of this,
`not only is the tip end portion 65 of the locking member 40'
`removed from the locking hole 45, but also the tip end
`portion 60a of the pressing piece 60 enters into the locking
`hole 45. In the unlocked state, the second pipe 12 can move
`in the axial direction in respect to the first pipe 11, enabling
`adjustment of the length of the second pipe 12.
`[0034]
`When the second pipe 12 is moved in the axial direction
`in respect to the first pipe 11, the tip end portions 60a and
`61a of the pressing pieces 60 and 61 will be in a state
`wherein they are in contact with the inner surface of the
`first pipe 11, as depicted in FIG. 7. Additionally, when the
`lever 22 is operated to the locking position when the second
`pipe 12 has been extended to the desired length, then, in the
`same manner as with the pressing member 30 of the first
`embodiment, the second pipe 12 can be secured at the
`desired position by the frictional force.
`[0035]
`When embodying the present invention, obviously
`modifications can be made, in a range that does not deviate
`from the spirit or intent of the present invention, to the first
`and second pipes, and to the base member or lever, pressing
`member, locking member, stopping mechanism, and the
`like. Moreover, the pipe used in the present invention may
`be structured from a composite material that has, for
`example, a carbon fiber as the main material thereof, rather
`than a light metal such as an aluminum alloy, or the like.
`[0036]
`[Effects of the Invention]
`Given the invention described in claim 1, the first pipe
`and the second pipe are secured together through the
`locking member fitting into the locking hole in a state
`wherein the telescoping tube is extended, thus enabling a
`large load to be born in the axial direction. This makes it
`possible to avoid a sudden collapse of the second pipe
`when a load is applied.
`[0037]
`Given the invention set forth in claim 2, because the tip
`end portion of the locking member faces the locking hole in
`the state wherein the position of the second pipe in the axial
`direction is constrained by the stopper mechanism, the tip

`
`end portion of the locking member can be inserted into the
`locking hole through operating the lever to the locking
`position when in this state, enabling the locking operation
`to be carried out easily.
