Description

Coffin handle device

The present invention relates to an extendable handle device attached to a bag.

A cage having a caster at the bottom and a handle device (carry bar) that can be extended at the top is known. Such bags are generally called carry bags, trunk cases, suitcases, and trolley bags. When the user of the scissors passes on a flat road surface, the user pulls the scissors by extending the handle device and gripping the grip portion of the handle device. On the other hand, when passing on a road surface having a level difference such as a staircase, the user contracts the handle device, holds a lifting handle attached to the bag, and lifts the bag to pass. Since there are relatively many steps in a general daily environment, the user often has the opportunity to extend and contract the handle device, and may feel annoyed.

In order to reduce the troublesomeness associated with the expansion and contraction of the handle device, there is one in which the handle device is extended by the operation of an operation button provided on the grip portion (for example, Patent Document 1). In the handle device according to Patent Document 1, a pair of telescopic struts composed of an outer cylinder and an inner cylinder, a gripping part spanned between the tips of the pair of inner cylinders, and a relative position of the inner cylinder with respect to the outer cylinder A position holding device to be fixed, a release switch provided in the gripping part to release the operation of the position holding device, and provided between the outer cylinder and the inner cylinder, and urged in a direction to project the inner cylinder from the outer cylinder. A compression coil spring. This handle device releases the position holding device by operating the release switch, causes the inner cylinder to protrude from the outer cylinder by the biasing force of the compression coil spring, and extends the handle device.

US Pat. No. 7,370,740

However, the handle device according to Patent Document 1 has a problem that the handle device expands when it is not intended due to an object or the like coming into contact with the release switch. For example, when a handle device is unintentionally extended when loading a bag into a luggage compartment such as a vehicle, the loading operation may be hindered. Also, when extending the handle device, the user needs to extend his hand to the release switch provided in the handle device gripping part. It is hard to say that the work burden has been greatly reduced. Similarly to the conventional handle device, when the inner cylinder is stored in the outer cylinder (the handle device is contracted), it is necessary to hold the grip portion and push it into the heel side. There is a problem of pinching hands and fingers.

The present invention has been made in view of the above background, and an object thereof is to provide a bag handle device that can reduce the troublesomeness of the expansion and contraction work.

In order to solve the above-mentioned problems, the present invention is a telescopic handle device (30) attached to the heel (10), which has a telescopic structure that can be extended and contracted, and is attached to the heel body (12). (31L, 31R), a gripping part (32) attached to the column part, and an urging device (110, 220) for urging the column part in a contracting direction.

According to this configuration, since the handle device is always urged by the urging device, when the external force that maintains the handle device in the extended state disappears, the handle device naturally changes to the contracted state. Accordingly, for example, the user can contract the handle device only by releasing the hand that holds the grip portion.

Another aspect of the present invention is characterized in that an attenuation device (80, 210) for reducing the contraction speed of the support column is provided.

According to this configuration, the change of the handle device to the contracted state is decelerated, and it is possible to prevent the hand from being caught between the heel and the grip portion. Further, the slow operation of the handle device can prevent the generation of a collision sound that is generated when the contraction is completed, can produce a high-class feeling, and can increase the commercial value of the handle device.

In another aspect of the present invention, the support column includes an outer cylinder (36) attached to the flange and an inner cylinder (37) slidably supported by the outer cylinder, and the damping device The cylinder (81) attached to the inner cylinder, the piston head (82) slidably provided in the cylinder, the base end portion is connected to the piston head, and the tip end portion is A piston rod (83) protruding from the cylinder, and a pressing portion (95) capable of contacting the tip end portion (91) of the piston rod is provided in a portion integral with the outer cylinder; The tip portion of the rod contacts the pressing portion when the immersing length of the inner cylinder with respect to the outer cylinder exceeds a predetermined length, and the piston rod is immersed in the cylinder. Being pressed by the pressing part And features.

According to this configuration, since the damping device decelerates the contraction speed only at the end of the change when the column portion changes from the extended state to the contracted state, it is possible to prevent the user from being bothered.

Another aspect of the present invention is characterized in that the pressing portion has an engaging portion (96) in which the tip portion of the piston rod is detachably engaged. The engagement between the distal end portion and the engaging portion is performed by mechanical hooking, adsorption, adsorption by magnetic force, or the like.

According to this configuration, the piston rod can be pulled out from the cylinder when the support column is displaced from the contracted state to the extended state. In addition, after the piston rod is pulled out from the cylinder, the engagement between the tip end portion of the piston rod and the engagement hole is released, so that the change of the column portion to the protruding state is not hindered.

Another aspect of the present invention is a position holding device (lock device 60) that is provided on the inner cylinder and selectively engages with the outer cylinder to restrict sliding of the inner cylinder with respect to the outer cylinder. And an operation switch (122) provided in the grip portion for releasing the engagement of the position holding device with respect to the outer cylinder.

According to this configuration, the handle device contracts when the user operates the operation switch.

In another aspect of the present invention, a pair of the support columns are provided at a predetermined interval, the gripping unit is spanned between the pair of support columns, and the biasing device is a pair of the support columns. The attenuation device is provided on the other of the pair of support columns.

According to this configuration, since the urging device and the damping device are distributed and arranged on the pair of column portions, the device configuration can be simplified.

According to the above configuration, since the handle device automatically changes to the contracted state, it is possible to reduce the annoyance that the user feels when expanding and contracting the handle device.

right support columns

31L and 31R, a grip 32 provided so as to connect the upper ends of the left and

right support columns

31L and 31R, and the left and

right support columns

31L and 31R. An upper bracket 33 and a lower bracket 34 for fixing are provided. The left and

right support columns

31L and 31R have a telescopic structure including an outer cylinder 36 having both ends opened and an inner cylinder 37 slidably supported by the outer cylinder 36. The cross-sectional shapes of the outer cylinder 36 and the inner cylinder 37 may be various shapes such as a circular shape, an oval shape, a rectangular shape, a square shape, and other polygonal shapes.

The lower bracket 34 is attached to the inner surface side of the rear side surface 24. Note that the lower bracket 34 may be coupled to a reinforcing member or a caster base 18 which is a skeleton of the heel body 12. The lower bracket 34 is formed with two tubular portions 38 having vertical axes (see FIG. 2). The tubular portion 38 has an upper inside formed in a shape corresponding to the outer shape of the outer cylinder 36, and a lower inside formed narrower than the upper inside.

The upper bracket 33 is attached to the rear side surface 24 and the upper surface 20 so as to straddle the ridge line between the rear side surface 24 and the upper surface 20. A concave portion 39 is formed in the central portion of the upper bracket 33 so as to be recessed toward the inside of the bag main body 12. The concave portion 39 is formed with two through holes 40 penetrating in the vertical direction. The through hole 40 is formed in a shape corresponding to the outer shape of the outer cylinder 36. The concave portion 39 is formed in a size that can accommodate the grip portion 32 when the

column portions

31L and 31R contract.

The outer cylinders 36 are fitted to the tubular portions 38 of the lower bracket 34 at the respective lower ends and are fitted into the through holes 40 of the upper bracket 33 so that the outer cylinders 36 are parallel to each other and vertically. The bag body 12 is supported so as to extend. The upper end of the outer cylinder 36 is substantially flush with the recess 39 of the upper bracket 33, and the inner cylinder 37 extends upward from the recess 39.

Each inner cylinder 37 has an upper end opened, and a lower end closed by a bottom 45. On the outer surface side of the bottom portion 45, a male screw portion 46 coaxial with the axis of the inner cylinder 37 is formed. A through hole 47 coaxial with the axis of the inner cylinder 37 is formed at the center of the bottom 45 and the male threaded portion 46. A lid member 48 is fitted to the upper end portion of each inner cylinder 37. The lid member 48 has a bottomed cylindrical shape with an outward flange at the open end, the cylindrical portion is fitted inside the inner cylinder 37, and the flange is caught by the upper end surface of the inner cylinder 37. It is supported on the upper end of the cylinder 37. A through hole 50 coaxial with the axis of the inner cylinder 37 is formed in the bottom 49 of the lid member 48.

In the inner cylinder 37, a connecting shaft 51 is arranged coaxially with the axis of the inner cylinder 37. The connecting shaft 51 passes through the through hole 47 and the through hole 50 and extends outward from the inner cylinder 37. At the upper end portion of the connecting shaft 51, a head portion 52 having a stepped portion and having an enlarged diameter is formed. A compression coil spring 54 is interposed between the lower surface of the head 52 and the inner surface of the bottom 49 of the lid member 48. Thereby, the connecting shaft 51 is urged upward with respect to the inner cylinder 37. A drive cam member 56 having a slope inclined with respect to the axis of the connecting shaft 51 is attached to the lower end of the connecting shaft 51.

A lock device (position holding device) 60 is attached below the inner cylinder 37. The lock device 60 includes a cylindrical casing 61 having both ends opened, and a lock pin 62 and a compression coil spring 63 provided in the casing 61. The casing 61 is formed in a shape that substantially matches the outer shape of the inner cylinder 37, and

female screw portions

64 and 65 are formed at both ends of the inner surface thereof. The locking device 60 is connected to the lower end portion of the inner cylinder 37 by the female screw portion 64 on the upper end side of the casing 61 being screwed with the male screw portion 46 of the inner cylinder 37. A through hole 66 is formed in the side surface of the casing 61.

The lock pin 62 is supported in the casing 61 so as to be slidable in the radial direction of the casing 61. The distal end portion of the lock pin 62 is displaced in the radial direction of the casing 61 and can pass through the through hole 66. A compression coil spring 68 is interposed between the base end portion of the lock pin 62 and the inner surface of the casing 61. The lock pin 62 is urged by the compression coil spring 62 in a direction in which a tip portion thereof passes through the through-hole 66 and moves radially outward of the casing 61.

The outer cylinder 36 is formed with three first to third positioning holes 71, 72, 73 that communicate the inner surface and the outer surface in the radial direction at predetermined intervals in the length direction of the outer cylinder 36. . The through hole 66 is opposed to the first positioning hole 71 in a state where the immersion length of the inner cylinder 37 with respect to the outer cylinder 36 is maximized (a contracted state of the

support column portions

31L and 31R), In a state where the length is minimum (the column portions 31L and 1R are extended), the third positioning hole 73 is opposed to the inner tube 37 and the immersion length of the inner tube 37 relative to the outer tube 36 is medium (the column portions 31L and 1R). In the intermediate state) opposite to the second positioning hole 72. The distal end portion of the lock pin 62 enters the first positioning hole 71 when the

support portions

31L and 31R are contracted (see FIG. 2), and enters the third positioning hole 73 when the

support portions

31L and 31R are extended. In the intermediate state between the

support column portions

31L and 31R, the second cylindrical positioning member 72 is inserted into the second positioning hole 72 and holds the relative position of the inner cylinder 37 with respect to the outer cylinder 36.

Further, a driven cam member 68 having a slope that slides on the slope of the drive cam member 56 is formed at the base end of the lock pin 62. When the drive cam member 56 is displaced downward (when the protruding length of the connecting shaft 51 downward from the inner cylinder 37 is increased), the driven cam member 68 is pressed by the drive cam member 56, and the lock pin 62 is compressed. It is displaced inward of the casing 61 against the biasing force of the spring 63. When the lock pin 62 is displaced inward of the casing 61, the tip end portion of the lock pin 62 is disengaged from the first to third positioning holes 71 to 73, and the inner cylinder 37 can be relatively displaced with respect to the outer cylinder 36.

A damping device (air damper device) 80 is attached to the lower end of the locking device 60 of the left column 31L. The damping device 80 includes a cylinder 81, a piston head 82, a piston rod 83, and a pressing portion 95. The cylinder 81 has a cylindrical shape with its upper end closed, and its lower end is closed with a lid 86 formed with a through hole 85 through which the piston rod 83 can be inserted. The outer shape of the cylinder 81 is formed in a size that approximately matches the outer shape of the inner cylinder 37. A male screw portion 88 that is screwed into the female screw portion 65 of the casing 61 is formed at the upper end portion of the cylinder 81. When the male screw portion 88 is screwed with the female screw portion 65, the cylinder 81 is coaxially connected to the inner cylinder 37 via the casing 61.

The piston head 82 is slidably accommodated in the cylinder 81, and divides the space in the cylinder 81 up and down. A plurality of orifices 89 parallel to the axial direction of the cylinder 81 are formed in the piston head 82 so as to communicate with the bisected space in the cylinder 81. The piston rod 83 has a base end connected to the center of the piston head 82, and a distal end extending through the through hole 85 of the lid 86 and extending to the outside of the cylinder 81.

The air is sealed in the cylinder 81, and when the piston head 82 is displaced in the cylinder 81, the air passes through the orifice 89 and causes flow resistance. Thereby, the displacement speed with respect to the cylinder 81 of the piston head 82 and the piston rod 83 is reduced (attenuated). The cylinder 81 may be filled with an incompressible fluid such as oil instead of air.

A spherical locking end 91 is formed at the tip of the piston rod 83. Further, a plate-like flange portion 92 is attached at a position spaced from the locking end portion 91 of the piston rod 83 by a predetermined distance. The lower bracket 34 is attached with a pressing portion 95 that abuts the locking end portion 91 and presses the piston rod 83 in a direction to be immersed in the cylinder 81. Since the pressing portion 95 and the outer cylinder 36 are both fixed to the lower bracket 34, the relative positional relationship does not change and is integrated. The pressing portion 95 opens upward and engages with a locking hole 96 into which the locking end portion 91 is fitted, and a locking end portion 91 fitted into the locking hole 96, and is flexible so as to prevent it from coming off. And a claw portion 97. As a result, the locking end portion 91 fitted in the locking hole 96 is locked by the claw portion 97 until the predetermined value of the removal force is applied, and the connected state with the pressing portion 95 is maintained. . The flange portion 92 of the piston rod 83 comes into contact with the upper surface of the pressing portion 95 in a state where the locking end portion 91 is fitted in the locking hole 96.

The lower end of the lock device 60 of the right column 31R is connected to the urging device 110. The urging device 110 includes a wire 111, a reel 112,

pulleys

113 and 114, and a constant load spring device 115. One end of the wire 111 is connected to the lower end of the casing 61 of the lock device 60, and the other end is fixed and wound around the reel 112. Between the casing 61 and the reel 112,

pulleys

113 and 114 for changing the advancing / retreating direction of the wire 111 are provided, and the wire 111 is wound around the

pulleys

113 and 114.

The constant load spring device 115 includes a first drum 116, a second drum 117, one end connected to the first drum 116 and the other end connected to the second drum 117, and the first and

second drums

116, 117. A thin leaf spring 118 wound in an S shape is provided therebetween. The second drum 117 is connected to the reel 112 so as to rotate coaxially and integrally. The thin plate spring 118 is more stable in the state of being wound around the first drum 116 than in the state of being wound around the second drum 117, and the second drum 117 sends out the thin plate spring 118 by the thin plate spring 118. It is biased in the rotation direction (counterclockwise direction in FIGS. 2 to 5). The direction in which the second drum 117 is urged coincides with the direction in which the reel 112 winds the wire 111. In this way, the constant load spring device 115 is biased in the rotational direction in which the reel 112 winds the wire 111. That is, the inner cylinder 37 is constantly urged downward in the outer cylinder 36 (that is, the direction in which the inner cylinder 37 is immersed in the outer cylinder 36) by the constant load spring device 115 via the lock device 60.

The grip portion 32 includes a U-shaped hollow housing 121 that opens downward, and an operation switch 122 supported by the housing 121. The housing 121 includes

downward openings

124 and 125 that communicate the outside and the inside at both ends. In addition, the housing 121 includes an upward opening 126 that communicates the outside and the inside at an intermediate portion in the longitudinal direction. The operation switch 122 is provided in the housing 121, and both ends 127 thereof extend to positions corresponding to the

openings

124 and 125. The operation switch 122 has a button portion 128 projecting from the opening 126 of the housing 121 and projecting to the outside of the housing at an intermediate portion thereof. A compression coil spring 129 is interposed between the lower surface of the operation switch 122 and the inner surface of the housing 121, and the button portion 128 of the operation switch 122 is urged in a direction protruding from the opening 126 of the housing 121.

The upper ends of the left and right inner cylinders 37 are fitted into the

openings

124 and 125 of the housing 121, and the housing 121 and each inner cylinder 37 are connected by screws (not shown). In this state, the lower portions of both end portions 127 of the operation switch 122 are in contact with the head portions 52 of the left and right connecting shafts 51. As a result, when the button 128 is pushed inward of the housing 121 against the urging force of the compression coil spring 129 and the operation switch 122 is displaced downward with respect to the housing 121, the left and right connecting shafts 51 are compressed. The inner cylinder 37 and the lock device 60 are displaced downward against the urging force of the spring 54.

Next, the operation of the handle device 30 of the first embodiment will be described with reference to FIGS. FIG. 2 shows a contracted state of the left and

right support columns

31L and 31R. As shown in FIG. 2, in the contracted state of the column portions 31 </ b> L and 31 </ b> R, the distal end of the lock pin 62 of the locking device 60 enters the first positioning hole 71 of the outer cylinder 36 and the relative position of the inner cylinder 37 with respect to the outer cylinder 36. Is fixed. In this state, the piston rod 83 of the damping device 80 is most immersed in the cylinder 81, that is, the piston head 82 is displaced most upward in the cylinder 81. The locking end portion 91 is fitted in the locking hole 96, and the flange portion 92 is in contact with the upper side surface of the pressing portion 95.

When the user grips the housing 121 of the grip portion 32 and pushes the button portion 128 of the operation switch 122 against the urging force of the compression coil spring 129 from the state shown in FIG. The connecting shaft 51 is displaced downward with respect to the inner cylinder 37 and the casing 61 of the lock device 60. As a result, the drive cam member 56 attached to the lower end portion of the connecting shaft 51 is displaced downward to press the driven cam member 68, and the lock pin 62 resists the urging force of the compression coil spring 63 and enters the casing 61. Retract. Therefore, the distal end portion of the lock pin 62 is detached from the first positioning hole 71, and the inner cylinder 37 can be slid relative to the outer cylinder 36. In this state, the user can extend the left and

right support columns

31L and 31R by pulling the grip 32 upward.

At this time, since the locking device 60 and the inner cylinder 37 of the right column portion 31R are urged downward by the urging device 110, the user moves the grip portion 32 upward against the urging force of the urging device 110. It is necessary to pull it up. When the grip portion 32 is pulled up and the inner cylinder 37 is displaced upward with respect to the outer cylinder 36, the wire 111 is sent out from the reel 112. At this time, the thin leaf spring 118 wound around the first drum 116 is sent out and wound around the second drum 117.

As shown in FIG. 3, when pulling up the

struts

31L, 31R from the contracted state of the left and

right struts

31L, 31R (FIG. 2), the piston head 82 is locked until reaching the lower end in the cylinder 81. The end portion 91 maintains the state of being locked in the locking hole 96. When the grip 32 and the inner cylinder 37 are further pulled up after the piston head 82 reaches the lower end in the cylinder 81, the claw 97 is bent and the locking state between the locking end 91 and the locking hole 96 is released. The Thus, when extending the

column portions

31L and 31R, the damping device 80 is changed to a state in which the piston rod 83 protrudes most from the cylinder 81.

FIG. 4 shows the extended state of the left and

right support columns

31L and 31R. As shown in FIG. 4, when the user releases the force to push the button portion 128, the operation switch 122 is displaced upward in the housing 121 by the compression coil spring 129. Since the left and right connecting shafts 51 are not pressed by the operation switch 122, they are urged by the compression coil spring 54 and displaced upward in the inner cylinder 37, and the drive cam member 56 is displaced upward in the casing 61. As a result, the driven cam member 68 is not pressed by the drive cam member 56, the lock pin 62 is urged by the compression coil spring 63, and the tip portion thereof enters the third positioning hole 73. In this way, the relative movement of the inner cylinder 37 with respect to the outer cylinder 36 is restricted, and the

support columns

31L and 31R are maintained in the extended state.

Although not shown, the end of the lock pin 62 can be inserted into the second positioning hole 72 of the outer cylinder 36 to maintain the

column portions

31L and 31R in an intermediate state.

Next, a method for changing the

strut portions

31L and 31R from the expanded state (see FIG. 4) to the contracted state (see FIG. 2) will be described. First, the user grips the grip portion 32 and presses the button portion 128 of the operation switch 122 to release the engagement between the third positioning hole 73 and the lock pin 62. From this state, the user displaces the operation switch 122 while pressing it until the

column portions

31L and 31R are contracted more than the intermediate state. At this time, since the inner cylinder 37 is urged by the urging device 110 in the direction in which the inner cylinder 37 is pulled into the outer cylinder 36, the user can contract the

column portions

31L and 31R without applying any force.

Next, when the user releases the pressing of the operation switch 122 and releases the grip portion 32, the inner cylinder 37 is urged by the urging device 110 and pulled into the outer cylinder 36. FIG. 5 is a diagram illustrating a state immediately before the

support columns

31L and 31R are in a contracted state. As shown in FIG. 5, when the immersion length of the inner cylinder 37 with respect to the outer cylinder 36 reaches a predetermined length, the locking end portion 91 of the piston rod 83 reaches the pressing portion 95. When the immersion length of the inner cylinder 37 with respect to the outer cylinder 36 is further increased from the state shown in FIG. 5, the locking end portion 91 bends the claw portion 97 and fits into the locking hole 96, and the flange portion 92 is the pressing portion. 95 abuts on the upper surface.

Even after the locking end 91 is fitted in the locking hole 96, the inner cylinder 37 is urged by the urging device 110 and is displaced downward in the outer cylinder 36. At this time, since the relative position of the piston head 82 is fixed with respect to the outer cylinder 36, the cylinder 81 is relatively displaced downward with respect to the piston head 82. When the relative position between the cylinder 81 and the piston head 82 changes, a flow resistance of air passing through the orifice 89 of the piston head 82 is generated, so that the relative speed of the inner cylinder 37 with respect to the outer cylinder 36 is reduced (attenuated). That is, the contraction speed of the

column portions

31L and 31R is reduced by the attenuation device 80.

Displacement of the inner cylinder 37 downward (immersion direction) with respect to the outer cylinder 36 is completed when the piston head 82 abuts on the upper end surface inside the cylinder 81. With the piston head 82 in contact with the upper end surface inside the cylinder 81, the through hole 66 and the first positioning hole 71 face each other, and the lock pin 62 enters the first positioning hole 71. In this way, the

support columns

31L and 31R are in a contracted state, and the relative position of the inner cylinder 37 with respect to the outer cylinder 36 is fixed (see FIG. 2).

In the contraction method of the

support column portions

31L and 31R described above, the user grips the grip portion 32 while pressing the operation switch 122, and the

support column portions

31L and 31R are contracted from the intermediate state to the contracted state. A person can also contract the

support columns

31L and 31R simply by pressing the operation switch 122. When the user presses the button portion 128 of the operation switch 122 once with the lock pin 62 entering the third positioning hole 73, the lock pin 62 is detached from the third positioning hole 73 and biased to the biasing device 110. Thus, the inner cylinder 37 is displaced downward with respect to the outer cylinder 36. This displacement is stopped when the lock pin 62 enters the second positioning hole 72. Then, when the button portion 128 of the operation switch 122 is pressed again with the lock pin 62 entering the second positioning hole 72, the lock pin 62 is detached from the second positioning hole 72 and is biased by the biasing device 110. As a result, the

support columns

31L and 31R change to the contracted state. At this time, as described above, the engaging end portion 91 of the piston rod 83 engages with the pressing portion 95, the damping device 80 is contracted, and the contraction speed of the inner cylinder 37 is decreased.

In the handle device 30 according to the first embodiment, the

struts

31L and 31R can be changed to the contracted state simply by pressing the operation switch 122 provided in the grip 32. At the end of the change to the contracted state, the damping device 80 acts to reduce the displacement speed of the inner cylinder 37 with respect to the outer cylinder 36, so the user places his hand between the grip portion 32 and the upper bracket 33. The risk of pinching is reduced, and a high-quality feeling can be imparted to the operation. Further, the attenuation device 80 can alleviate the collision between the grip portion 32 and the outer cylinder 36 when the contraction is completed, and can prevent the occurrence of a collision sound. Since the damping device 80 works only when the

support columns

31L and 31R are close to the contracted state, the damping device 80 realizes a quick contracting operation and does not make the user feel bothered.

Second Embodiment
The handle device 200 of the second embodiment differs from the handle device 30 of the first embodiment in the configuration of the damping device 210 and the biasing device 220. Of the configuration of the handle device 200, the same configuration as that of the handle device 30 is denoted by the same reference numeral and description thereof is omitted.

The damping device 210 includes a rack 211, a pinion 212, and a rotary damper 213. The rack 211 extends on the outer surface of the casing 61 of the left side locking device 60 in parallel with the axial direction of the casing 61. The left outer cylinder 36 is formed with a slit 231 that extends parallel to the axial direction of the outer cylinder 36 so that the inner cylinder 37 does not contact the rack 211 when the inner cylinder 37 is displaced up and down. The tooth part of the rack 211 protrudes outward of the outer cylinder 36 through the slit 231. The rotary damper 213 includes a casing 215 fixed to the lower bracket 34, and a rotating shaft 216 having a base end portion rotatably supported in the casing 215 and a distal end portion protruding from the casing 215. The casing 215 is filled with oil and applies rotational resistance to the rotating shaft 216. The pinion 212 is connected to the tip of the rotation shaft 216.

The rack 211 and the pinion 212 are configured so that the rack 211 and the pinion 212 are engaged with each other so that the inner cylinder 37 is engaged with the outer cylinder 36 when the immersion length of the rack 211 and the pinion 212 is equal to or greater than a predetermined length. The length and the position of the rotary damper 213 and the pinion 212 are set. When the rack 211 is engaged with the pinion 212, the rack 211 receives the rotational resistance of the rotary damper 213, and the displacement speed is reduced.

The urging device 220 includes a tension coil spring having one end connected to the lower end of the casing 61 of the right lock device 60 and the other end connected to a spring seat 221 protruding from the lower bracket 34. The right side locking device 60 and the inner cylinder 37 are constantly urged by the urging device 220 in the direction toward the lower side in the outer cylinder 36, that is, the direction in which the column portion 31R contracts.

With the configuration described above, the handle device 200 of the second embodiment, like the handle device 30 of the first embodiment, retracts the

support columns

31L and 31R by simply pressing the operation switch 122 provided on the grip 32. Can be changed. Then, at the final stage of the change to the contracted state, the rack 211 and the pinion 212 are engaged with each other, the resistance force of the rotary damper 213 is applied to the inner cylinder 37, and the contraction speeds of the

column portions

31L and 31R can be reduced.

This is the end of the description of the specific embodiment, but the present invention is not limited to the above embodiment and can be widely modified. The outer cylinder 36, the inner cylinder 37, the grip portion 32, and the lock device 60 can have various configurations. For example, in the above-described embodiment, the left and

right support columns

31L and 31R are configured, but one support column may be provided. The biasing device 110 may bias the inner cylinder with respect to the outer cylinder using an attractive force based on magnetic force.
