In addition, the bottom of the internal cylindrical body 23 is formed to provide an inclined surface which provides the side of the pair of protruded strips 23 b with a larger dimension, and the other side with a smaller dimension.
The pressure-contacting annular body 24 is provided with a substantially square protrusion 24 a on one side of the circumference thereof that rises upward as it protrudes outward, such that, when the internal cylindrical body 23 is placed thereon, the protrusion 24 a is fitted between the pair of protruded strips 23 b of the internal cylindrical body 23.
The lower cylindrical body 41 is integrally jointed to the upper cylindrical body 11, the second pole 4 being penetratable therethrough, and as shown in FIG. 3, is configured such that the upper end of the first pole 2 is integrally fitted and fixed to the bore part thereof.
In the circumferential part of the lower cylindrical body 41, on one side thereof, a lever supporting part 42 which is jointed to the lever loading part 12, being provided with a shape corresponding to this lever loading part 12, is integrally protruded, and at the protruding end thereof, a guide opening 43 having a certain width is provided.
On one side of the circumference of the lower cylindrical body 41, a prism-shaped protruded piece 45 in which a through-hole 44 for fixing the operation lever 31 is formed is protruded along the lengthwise direction thereof. Further, on the other side of the circumference of the lower cylindrical body 41, a support part 46 to which the protruding part 14 of the upper cylindrical body 11 is jointed is provided. And, in a location above the support part 46 in the lower cylindrical body 41, a threaded hole 47 for the locking screw 53 is provided.
The upper end of the lower cylindrical body 41 is adapted to provide an inclined part 48 which has a lower profile on the side of the lever supporting part 42, and a higher one on the side of the support part 46. And, on this inclined part 48, the pressure-contacting annular body 24, internal cylindrical body 23, and coil spring 22 are placed in this order.
The operation lever 31 is engaged between the lever loading part 12 in the upper cylindrical body 11 and the lever supporting part 42 in the lower cylindrical body 41.
In the upper portion of the operation lever 31, a pushing-up piece 32 which is engaged with the bottom of the protrusion 24 a of the pressure-contacting annular body 24 for raising one side of the pressure-contacting annular body 24, the tip thereof being pointed, and a guide groove 33 into which the protruded piece 13 is fitted from above are provided.
In addition, on the lower side of the guide groove 33, a thinner-wall part 34 which is displaced, while being guided by the guide opening 43 formed at the protruding end of the lever supporting part 42 is provided with an operation piece 35 hanging downward from this thinner-wall part 34.
The inside of the operation piece 35 is formed to provide a recess part substantially □-shaped in the horizontal section, and has a pair of through-holes 36 for allowing a securing pin 51 with a holding part 52 expanded in the horizontal direction to penetrate therethrough.
In addition, the operation piece 35 in the operation lever 31 is configured to be fitted to or removed from the protruded piece 45 provided on the lower cylindrical body 41.
In other words, by fitting the operation lever 31 to the protruded piece 45, and aligning the pair of through-hole 36 with the through-hole 44 in the protruded piece 45 before inserting the securing pin 51, the operation lever 31 is fixed to the lower cylindrical body 41.
As shown in FIG. 5, the second butting body 5 is disk-shaped on the upper end side, including a butting base body 71 in which a later described support cylindrical body 72 in the shape of a cylinder is protruded downward; the support cylindrical body 72 which, being blocked on the upper end side, is fitted into the opening part of the butting base body 71, and into which the upper end of the second pole is removably loaded; a support piece 73 which is provided inside of the butting base body 71; an urging spring 74 which is disposed between the support piece 73 and the upper end face of the support cylindrical body 72; and a butting auxiliary body 75 which is removably disposed on the side of the upper end face of the butting base body 71, being thin disk-shaped and made of such a material as rubber.
And, when the upper end of the second pole is loaded into the support cylindrical body 72 and the upper end face of the butting base body 71 is butted against the ceiling 62, the urging spring 74 causes the butting base body 71 to be pressure-contacted with the ceiling 62 by the resilience. At this time, the flexibility of the butting auxiliary body 75 prevents the ceiling surface from being damaged.
Next, the operation of the telescopic prop-up pole device 1 according to the present embodiment 1 will be described.
As shown in FIG. 1, the telescopic prop-up pole device 1 according to the present embodiment 1 is vertically fixed and disposed between the floor 61 and the ceiling 62 in the prop-up state by vertically erecting the first pole 2 on the floor 61 through the first butting body 3, for example, and causing the second butting body 5 disposed on the upper end of the second pole 4 telescopably jointed to the first pole 2 through the telescoping adjustment body 6 to be pressure-contacted with the ceiling 62. At this time, the telescoping adjustment body 6 is operated as follows.
The tip of the locking screw 53 is butted against the circumference of the second pole 4 through the hole 14 a of the upper cylindrical body 11 and the threaded hole 47 of the lower cylindrical body 41, locking the second pole 4.
In addition, as shown in FIG. 3, the pressure-contacting annular body 24 in the pole pressure-contacting/releasing part 21 is disposed on the inclined part 48 of the lower cylindrical body 41 in an inclined state where one side being in a lower position and the other side being in a higher position, thereby, one side (the side of the pushing-up piece 32) and the other side in the bore part of the pressure-contacting annular body 24 being slightly bulged toward the circumference side of one side and the other side of the second pole 4 fitted into the first pole 2, respectively.
Further, the pressure-contacting annular body 24 is pressed downward in FIG. 3 by the coil spring 22 through the internal cylindrical body 23.
As a result of this, one side and the other side in the bore part of the pressure-contacting annular body 24 are pressure-contacted with the circumference of one side and the other side of the second pole 4, respectively, thus the second pole 4 being in the state where it is fixed to the first pole 2 through the telescoping adjustment body 6.
Next, the telescoping operation of the telescopic prop-up pole device 1 according to the present embodiment 1 will be described below.
In order to adjust the protruding length of the second pole 4 with respect to the first pole 2 in the telescopic prop-up pole device 1, the locking screw 53 is first turned to remove it, which is followed by operating the operation piece 35 of the operation lever 31 inwardly (in the direction of arrow ‘a’ in FIG. 3).
Thereby, the pushing-up piece 32 of the operation lever 31 is displaced upward around a pivot of the protruded piece 13, whereby the protrusion 24 a of the pressure-contacting annular body 24 is pushed up upward.
As a result of this, as shown in FIG. 4, one side of the pressure-contacting annular body 24 and that of the internal cylindrical body 23 are pushed up upward against the resilience of the coil spring 22, resulting in the pressure-contacting annular body 24 being brought into a horizontal state (or a substantially horizontal state), with the state where one side and the other side in the bore part of the pressure-contacting annular body 24 are protruded toward the side of the circumference of one side and the other side of the second pole 4 fitted into the first pole 2 being cancelled, whereby the second pole 4 becomes free to be vertically moved, i.e., the second pole 4 becomes telescopable with respect to the lower pole, which results in the protruding length of the second pole 4 with respect to the first pole 2 being adjustable to a desired length.
Further, after the second pole 4 being adjusted to an appropriate length, canceling the operation force applied to the operation piece 35 constituting the operation lever 31 will automatically lower the pressure-contacting annular body 24 by the resilience of the coil spring 22 to allow it to restore the state as shown in FIG. 3, with the operation lever 31 also being returned to the position as shown in FIG. 3 under the action of the resilience of the coil spring 22.
When the telescopic prop-up pole device 1 is to be packaged or transported, the operation piece 35 is displaced to a position as shown in FIG. 4, and the securing pin 51 is utilized to fix the operation lever 31 to the protruded piece 45 for keeping the second pole 4 telescopable with respect to the first pole 2. This is because, if the pressure-contacting annular body 24 is left to be pressure-contacted with the circumference of the second pole 4, there is a possibility that the second pole 4 might be deformed by an external impact, resulting in the product having had a flaw, thus it is necessary that the second pole 4 be kept telescopable with respect to the first pole 2 for prevention of occurrence of a flaw.
With the telescopic prop-up pole device 1 according to the present embodiment 1, simply by making one-touch operation on the operation piece 35 of the operation lever 31 in the direction of arrow ‘a’, the second pole 4 can be brought into the state where it is telescopable with respect to the first pole 2, and the protruding length of the second pole 4 is adjustable to a desired length, and simply by canceling the operation force applied to the operation piece 35 of the operation lever 31, the second pole 4 can be automatically brought into the state where it is fixed with respect to the first pole 2.
Therefore, there can be realized and provided a telescopic prop-up pole device 1 with which the length adjustment of the second pole 4 and the fixing of the second pole 4 are extremely simple; the operability is good; and yet the durability is excellent because, unlike the conventional telescopic prop-up pole device which uses a turnbuckle type or screw type telescoping adjustment body, a scheme which uses the operation lever 31 for pushing up the pressure-contacting annular body 24 or canceling the pushing up is adopted.
In addition, because the second butting body 5 into which the upper end of the second pole 4 is schemed to have a built-in urging spring 74 for pressure contact, with a butting auxiliary body 75 being provided which is flexibly butted against the ceiling 62, there can be realized and provided a telescopic prop-up pole device 1 with which the second pole 4 can be positively mounted to the ceiling 62 with the ceiling surface being prevented from being damaged.

Embodiment 2

Next, a telescopic prop-up pole device 1A according to an embodiment 2 of the present invention will be described with reference to FIG. 6 to FIG. 9.
For the telescopic prop-up pole device 1A of the present embodiment 2, the same elements as those of the telescopic prop-up pole device 1 of the embodiment 1 as described above will be provided with the same reference numerals or letters, with the detailed explanation thereof being omitted.
As shown in FIG. 6 and FIG. 7, the basic configuration of the telescopic prop-up pole device 1A of the present embodiment 2 is substantially the same as that of the telescopic prop-up pole device 1 of the embodiment 1. Specifically, the telescopic prop-up pole device 1A of the present embodiment 2 is characterized in that, instead of the aforementioned operation lever 31 of turning operation type, an operation lever 81 of pushbutton type has been adopted, and the geometries of the lever loading part 12 of the upper cylindrical body 11, and the lever supporting part 42 of the lower cylindrical body 41 have been changed to provide a lever loading part 12A and a lever supporting part 42A which slidably hold the operation lever 81 of pushbutton type in the direction of arrows ‘b’ and ‘c’ as shown in FIG. 8, and the other configuration is substantially the same as that of the telescopic prop-up pole device 1 of the embodiment 1.
More specifically, the operation lever 81 in the present embodiment 2 is engaged between the lever loading part 12A in the upper cylindrical body 11, and the lever supporting part 42A formed in the lower cylindrical body 41 such that it is slidable in the direction of arrows ‘b’ and ‘c’.
The operation lever 81 is configured to include a pushing-up piece 82 which, being located at the distal end thereof, is engaged with the bottom of a protrusion 24 a of the pressure-contacting annular body 24, the tip thereof being pointed, for pushing up one side of the pressure-contacting annular body 24; a sliding body 83 which, being located adjacent to the pushing-up piece 82, slides in the direction of arrows ‘b’ and ‘c’ inside the lever loading part 12A and lever supporting part 42A; and further, a pressing button 84 which, being located on the rear end side of the sliding body 83, is protruded from the protruding ends of the lever loading part 12A and lever supporting part 42A.
The operation of the telescopic prop-up pole device 1A of the present embodiment 2 that has adopted such an operation lever 81 of pushbutton type will be described with reference also to FIG. 8 and FIG. 9.
When the telescopic prop-up pole device 1A which has adopted the operation lever 81 according to the present embodiment 2 is vertically fixed and disposed in the prop-up state between the floor 61 and ceiling 62, the tip of the locking screw 53 is butted against the circumference of the second pole 4 through the hole 14 a of the upper cylindrical body 11 and the threaded hole 47 of the lower cylindrical body 41, locking the second pole 4, in the same manner as shown in FIG. 1.
At this time, the telescoping adjustment body 6 and the operation lever 81 are operated as follows. As shown in FIG. 8, the pressure-contacting annular body 24 in the pole pressure-contacting/releasing part 21 is disposed on the inclined part 48 of the lower cylindrical body 41 in an inclined state where one side being in a lower position and the other side being in a higher position, thereby, one side (the side of the pushing-up piece 82) and the other side in the bore part of the pressure-contacting annular body 24 being slightly bulged toward the circumference side of one side and the other side of the second pole 4 fitted into the first pole 2, respectively.
Further, the pressure-contacting annular body 24 is pressed downward in FIG. 8 by the coil spring 22 through the internal cylindrical body 23.
As a result of this, one side and the other side in the bore part of the pressure-contacting annular body 24 are pressure-contacted with the circumference of one side and the other side of the second pole 4, respectively, thus the second pole 4 being in the state where it is fixed to the first pole 2 through the telescoping adjustment body 6.
In addition, the tip of the pushing-up piece 82 of the operation lever 81 is engaged with the bottom of the protrusion 24 a of the pressure-contacting annular body 24, and the pressing button 84 is in the state where it is protruded sideward from the protruding ends of the lever loading part 12A and lever supporting part 42A.
Next, in order to adjust the protruding length of the second pole 4 with respect to the first pole 2 in the telescopic prop-up pole device 1A, the locking screw 53 is first turned to remove it, which is followed by pushing in the pressing button 84 in the direction of arrow ‘b’ against the resilience of the coil spring 22.
Thereby, the pushing-up piece 82 of the operation lever 81 pushes upward the protrusion 24 a of the pressure-contacting annular body 24, and thus as shown in FIG. 9, one side of the pressure-contacting annular body 24 and that of the internal cylindrical body 23 are pushed up upward against the resilience of the coil spring 22, resulting in the pressure-contacting annular body 24 being brought into a horizontal state (or a substantially horizontal state), with the state where one side and the other side in the bore part of the pressure-contacting annular body 24 are protruded toward the side of the circumference of one side and the other side of the second pole 4 fitted into the first pole 2 being cancelled, whereby the second pole 4 becomes free to be vertically moved, i.e., the second pole 4 becomes telescopable with respect to the lower pole, which results in the protruding length of the second pole 4 with respect to the first pole 2 being adjustable to a desired length.
Further, after the second pole 4 being adjusted to an appropriate length, canceling the pressing force applied to the pressing button 84 will automatically lower the pressure-contacting annular body 24 by the resilience of the coil spring 22 to allow it to restore the state as shown in FIG. 8, with the operation lever 31 also being displaced in the direction of arrow ‘c’ to be returned to the position as shown in FIG. 8 under the action of the resilience of the coil spring 22.
With the telescopic prop-up pole device 1A according to the present embodiment 2, simply by making one-touch operation on the pressing pushbutton 84 of the operation lever 81 of pushbutton type in the direction of arrow ‘b’, the second pole 4 can be brought into the state where it is telescopable with respect to the first pole 2, and the protruding length of the second pole 4 is adjustable to a desired length, and simply by canceling the pressing force applied to the pressing pushbutton 84, the second pole 4 can be automatically brought into the state where it is fixed with respect to the first pole 2.
Therefore, there can be realized and provided a telescopic prop-up pole device 1A with which the length adjustment of the second pole 4 and the fixing of the second pole 4 are extremely simple; the operability is good; and yet the durability is excellent because, unlike the conventional telescopic prop-up pole device which uses a turnbuckle type or screw type telescoping adjustment body, a scheme which uses the operation lever 81 for pushing up the pressure-contacting annular body 24 or canceling the pushing up is adopted.
In addition, as is the case with the embodiment 1, there can be realized and provided a telescopic prop-up pole device 1A with which the second pole 4 can be positively mounted to the ceiling 62 through the second butting body 5 with the ceiling surface being prevented from being damaged.

Embodiment 3

Next, a telescopic prop-up pole device 1B according to an embodiment 3 of the present invention will be described with reference to FIG. 10.
The telescopic prop-up pole device 1B according to the present embodiment 3 is characterized in that it utilizes the telescopic prop-up pole device 1 of the embodiment 1, and further to the second pole 4 (or the first pole 2), a desired number (two in an example as shown in FIG. 10) of hooks 91 for hanging clothes such as a shirt, a towel, a hat, and the like, are fitted in a desired location thereof. The other configuration of the telescopic prop-up pole device 1B is the same as that of the embodiment 1.
According to the telescopic prop-up pole device 1B of the present embodiment 3, as is the case with the aforedescribed embodiments, there can be realized and provided a telescopic prop-up pole device 1B with which the operability is good; yet the durability is excellent because, unlike the conventional telescopic prop-up pole device which uses a turnbuckle type or screw type telescoping adjustment body; and further, the second pole 4 can be positively mounted to the ceiling 62 through the second butting body 5 with the ceiling surface being prevented from being damaged.
In addition, by adding a hook 91, there can be provided a telescopic prop-up pole device 1B which can function as a telescopic prop-up pole hanger for hanging clothes and the like.
In addition, as the telescopic prop-up pole device 1B according to the present embodiment 3, the telescopic prop-up pole device 1A in the embodiment 2 can duly be used, with a hook 91 being fitted to the second pole 4 (or the first pole 2) in a desired location thereof, and also in this case, the same function and effects can be provided.
