  1 is a perspective view showing a telescopic pen stand according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view showing the telescopic pen stand shown in FIG. FIG. 3 is a perspective view showing a state in which the telescopic pen stand shown in FIG. 1 is contracted. FIG. 4 is a cross-sectional view showing a state in which the telescopic pen stand shown in FIG. 1 is contracted. The telescopic pen stand 100 includes three cylinders 1, 2, and 3 having different diameters, and a second cylinder 10 having an outer diameter that is substantially the same as the inner diameter in the inner part 10 of the lowermost first cylinder 1. In this configuration, the cylindrical body 2 is inserted in a movable state, and a third cylindrical body 3 having an outer diameter that is substantially the same as the inner diameter thereof is inserted in the interior 11 of the second cylindrical body 2 in a movable state. Each cylindrical body 1, 2, 3 has spaces 31, 32, 33 having bottoms 27, 28, 29 between cylindrical outer walls 21, 22, 23 and inner side walls 24, 25, 26, The spaces 31, 32, 33 are opened upward and are equally divided in the circumferential direction by a plurality of walls 34, 35, 36 in the cylinder axis direction.

  A space 37 having a bottom 29 is formed inside the inner wall 26 of the uppermost third cylindrical body 3, and a bar-like handle 38 is provided on the bottom 29. The upper end of the handle 38 protrudes above the third cylinder 3, and a knob 39 is provided at the tip. Moreover, the height of each cylindrical body 1, 2, 3 is about 10 cm.

  The second cylinder 2 is movable in the vertical direction with respect to the first cylinder 1, and a flange 41 is formed on the inner upper portion of the first cylinder 1. On the other hand, a flange 42 is formed on the outer lower portion of the second cylindrical body 2. The second cylinder 2 is inserted into the first cylinder 1 in a movable state. When the second cylinder 2 is moved upward, the flange 42 of the second cylinder 2 is moved to the first cylinder 1. The second cylinder 2 does not come out of the first cylinder 1 due to interference with the flange 41 of the cylinder 1. The flanges 41 and 42 are provided with temporary fixing means 50 for fixing the second cylindrical body 2 at the upper position.

  As shown in FIG. 5, the temporary fixing means 50 includes a hole 52 provided on the lower surface of the flange 41 of the first cylinder 1 and having a side hole 51 inside, and a flange 42 of the second cylinder 2. And a key-shaped portion 53 that can be inserted into the hole 52 and can be inserted into the side hole 51. The temporary fixing means 50 inserts the key-shaped protrusion 54 into the hole 52, rotates the hole 52 together with the flange 41 of the first cylinder 1, and inserts the key-shaped portion 53 into the side hole 51, thereby The protrusions 53 and the holes 51 are engaged. Thereby, the movement of the cylinders 1 and 2 in the vertical direction is restricted. Further, when the first cylindrical body 1 is rotated in the opposite direction, the key-like portion 53 comes out of the side hole 51 and the engagement between the key-like protrusion 54 and the hole 52 is released. As a result, the second cylinder 2 can be inserted into the first cylinder 1. The cylinders 1 and 2 are inserted into the inner wall 24 of the flange 42 with a certain frictional force.

  Similarly to the above, the third cylinder 3 is movable in the vertical direction with respect to the second cylinder 2, and a flange 43 is formed on the inner upper portion of the second cylinder 2. On the other hand, a flange 44 is formed on the outer lower portion of the third cylinder 3. Although the 3rd cylinder 3 is inserted in the inside of the 2nd cylinder 2 in the movable state, if the 3rd cylinder 3 is moved upwards, the flange 44 of the said 3rd cylinder 3 will become 2nd. The third cylinder 3 is prevented from coming out of the second cylinder 2 by interfering with the flange 43 of the cylinder 2. The flanges 43 and 44 are provided with temporary fixing means 50 for fixing the third cylinder 3 at the upper position. As shown in FIG. 5, the temporary fixing means 50 includes a hole 52 provided on the lower surface of the flange 43 of the second cylinder 2 and having a side hole 51 therein, and a flange of the third cylinder 3. 44 and a key-like protrusion 54 that can be inserted into the hole 52 and the key-like portion 53 can be inserted into the side hole 51.

  The temporary fixing means 50 inserts the key-shaped protrusion 53 into the hole 51, rotates the key-shaped protrusion 54 together with the flange 43 of the second cylinder 2, and inserts the key-shaped portion 53 into the side hole 51. The key-like protrusion 54 and the hole 52 are engaged with each other. Thereby, the movement of the cylinders 2 and 3 in the vertical direction is restricted. Further, when the second cylindrical body 2 is rotated in the opposite direction, the key-like portion 53 comes out of the side hole 51 and the engagement between the key-like protrusion 54 and the hole 52 is released. As a result, the third cylinder 3 can be inserted into the second cylinder 2. The cylinders 2 and 3 are inserted with a certain frictional force against the surface of the inner wall 25 of the flange 44.

  As shown in FIGS. 3 and 4, when the cylinders 1, 2, 3 are disengaged by the temporary fixing means 50, the third cylinder 3 is moved into the second inner part 11 of the second cylinder 2. The cylindrical body 2 is inserted and stored in the interior 10 of the first cylindrical body 1. Since the flanges 42 and 44 of the cylinders 2 and 3 are in contact with the surfaces of the inner walls 24 and 25 of the cylinders 1 and 2 with a certain frictional force, each cylinder 2 can be lifted even if the handle 38 is lifted. , 3 holds the insertion state. Thereby, since this telescopic pen stand 100 becomes compact, it is convenient for handling and storage. The telescopic pen stand 100 can stand a writing instrument such as a pen in the divided spaces 31, 32, 33 in the extended state or the contracted state.

  FIG. 6 is an explanatory view showing an operation when the telescopic pen stand is extended. The cylinders 1, 2 and 3 are held in a contracted state due to frictional forces (see FIG. 1A), but as shown in FIG. The inertial force based on the weight of each of the cylinders 1 and 2 exceeds the frictional force, so that the first and second cylinders 1 and 2 move downward, and the flanges 41, 42, 43, and 44 interfere with each other. It stops at the maximum expansion / contraction position (see (b) of the figure).

  Then, the user holds the handle 38 and rotates the second cylinder 2 to be engaged and fixed to the third cylinder 3 by the temporary fixing means 50, and then the first cylinder 1 is fixed. It is rotated and engaged and fixed to the second cylinder 2 by the temporary fixing means 50. As a result, the telescopic pen stand 100 is held in an expanded state.

  Here, since the height of each of the cylinders 1, 2, and 3 is 10 cm, for example, when a pencil is placed in the divided space 31 of the first cylinder 1, the length of the pencil is approximately 20 cm. The pencil does not pop up from the upper end of the cylindrical body 2. That is, even if the longest pencil among the writing tools stands in the divided space 31, it will not be mixed with the stationery standing on the second cylinder 2, so that the writing instrument standing on the first cylinder 1 is recognized. Easy and easy to take. The same applies to the relationship between the second cylinder 2 and the third cylinder 3. Moreover, since the center of the 3rd cylinder 3 is the space 37, it is preferable to put bulky stationery, such as scissors. In addition, the height of each cylinder 1, 2, 3 is not limited to 10 cm. From the above viewpoint, it is preferable that the height of each cylindrical body 1, 2, 3 is 8 cm or more and 12 cm or less.

(Embodiment 2)
FIG. 7 is a perspective view showing a telescopic pen stand according to a second embodiment of the present invention. This telescopic pen stand 200 is characterized in that flanges or donut-shaped lids 62 and 63 are provided at the upper ends of the cylinders 2 and 3. Since the other configuration is the same as that of the telescopic pen stand 100 described in the first embodiment, the description thereof is omitted. Since the lids 62 and 63 have the same width in the radial direction as the spaces 31 and 32 above the cylinders 1 and 2, when the telescopic pen stand 100 is contracted, the spaces 31 and 32 are covered with the lids 62 and 63. (Not shown). In this way, no dust enters the spaces 31 and 32 when the telescopic pen stand 200 is contracted.

(Embodiment 3)
FIG. 8: is sectional drawing which shows the telescopic pen stand concerning Embodiment 3 of this invention. The telescopic pen stand 300 has substantially the same configuration as the telescopic pen stand 100 according to the first embodiment, but is the outer walls 22 and 23 of the second cylindrical body 2 and the third cylindrical body 3 in the height direction. This is characterized in that a locking device 70 is provided at the center of the. Since the other configuration is the same as that of the telescopic pen stand 100 described in the first embodiment, the description thereof is omitted.

  The locking device 70 is configured such that the upper end of a wedge-shaped stopper 71 is rotatable, and a lever 72 is provided obliquely upward on the stopper 71. The upper end of the lever 72 is further bent obliquely upward on the opposite side (bending portion 73). In a normal state, the stopper 71 is placed inside the surfaces of the outer walls 22 and 23 due to the weight of the lever 72. For this reason, when inserting the 2nd cylinder 3 and the 3rd cylinder 3, the said stopper 71 does not interfere with the cylinders 1 and 2 by the side of insertion. Subsequently, the lever 72 interferes with the cylinders 1 and 2 on the insertion side, but since the lever 72 rotates and escapes inside the outer walls 22 and 23, the cylinders 2 and 3 can be inserted as they are. On the other hand, when the cylinders 2 and 3 are inserted from the cylinders 1 and 2, the bent portion 73 of the lever 72 interferes with the upper parts of the cylinders 1 and 2 so that the lever 72 comes out. Then, since the stopper 71 enters inside, the cylinders 2 and 3 can be pulled out as they are.

  The telescopic pen stand 300 can maintain the extended state by the temporary fixing means 50 provided on the flanges 41 to 44 as described above, but the second cylindrical body 2 and the third cylindrical body 3 are provided by the locking device 70. The amount of drawer can be adjusted. That is, when the temporary fixation between the first cylinder 1 and the second cylinder 2 is released and the second cylinder 2 is inserted into the first cylinder 1, the lever 72 is pushed, so that the stopper 71 comes out of the outer wall and engages with the upper end of the first cylinder 1. Thereby, the second cylinder 2 is not completely inserted into the first cylinder 1 and only about half is inserted. Since the height of the second cylinder 2 is 10 cm, the second cylinder 2 is held in a state where it protrudes from the first cylinder 1 by about 5 cm. Similarly, the locking device 70 provided in the third cylinder 3 can insert the third cylinder 3 into the second cylinder 2 only about half and keep the state.

  By doing so, the height of the telescopic pen stand 300 can be freely adjusted. For example, it is convenient when the height of the storage space is insufficient or when writing tools that are not long are used.

(Embodiment 4)
FIG. 9: is sectional drawing which shows the telescopic pen stand concerning Embodiment 4 of this invention. This telescopic pen stand 400 has substantially the same configuration as the telescopic pen stand 100 according to the first embodiment, but the outer walls 21, 22, 23 of the first to third tubular bodies 1, 2, 3 and the direction of the tubular axis It is characterized in that gaps 437, 438, 439 are provided between the plurality of walls 434, 435, 436. Since the other configuration is the same as that of the telescopic pen stand 100 described in the first embodiment, the description thereof is omitted.

  Thus, by providing the gaps 437, 438, 439 between the outer walls 21, 22, 23 and the walls 434, 435, 436, it becomes easy to put a writing instrument in the space divided by the walls 434, 435, 436. . That is, since the space is divided to some extent by the walls 434, 435, and 436, it is easy to set up the writing tools, while providing the gaps 437, 438, and 439, more writing tools can be provided for one substantially divided space. You can enter.

  In addition, not only a writing instrument but stick-shaped things, such as a chopstick and a tool, can be stood in the expansion-contraction rod stand 100-400 of this invention.
