cylindrical body 23 is provided with the circular supportingshoulder part 23 a on the circumference thereof, and on one side thereof with a pair ofprotruded strips 23 b having a predetermined spacing. - In addition, the bottom of the internal
cylindrical body 23 is formed to provide an inclined surface which provides the side of the pair ofprotruded 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 substantiallysquare protrusion 24 a on one side of the circumference thereof that rises upward as it protrudes outward, such that, when the internalcylindrical body 23 is placed thereon, theprotrusion 24 a is fitted between the pair ofprotruded strips 23 b of the internalcylindrical body 23. - The lower
cylindrical body 41 is integrally jointed to the uppercylindrical body 11, thesecond pole 4 being penetratable therethrough, and as shown inFIG. 3 , is configured such that the upper end of thefirst 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, alever supporting part 42 which is jointed to thelever loading part 12, being provided with a shape corresponding to thislever 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-shapedprotruded piece 45 in which a through-hole 44 for fixing theoperation lever 31 is formed is protruded along the lengthwise direction thereof. Further, on the other side of the circumference of the lowercylindrical body 41, asupport part 46 to which theprotruding part 14 of the uppercylindrical body 11 is jointed is provided. And, in a location above thesupport part 46 in the lowercylindrical body 41, a threadedhole 47 for thelocking screw 53 is provided. - The upper end of the lower
cylindrical body 41 is adapted to provide aninclined part 48 which has a lower profile on the side of thelever supporting part 42, and a higher one on the side of thesupport part 46. And, on thisinclined part 48, the pressure-contactingannular body 24, internalcylindrical body 23, andcoil spring 22 are placed in this order. - The
operation lever 31 is engaged between thelever loading part 12 in the uppercylindrical body 11 and thelever supporting part 42 in the lowercylindrical body 41. - In the upper portion of the operation lever 31, a pushing-up
piece 32 which is engaged with the bottom of theprotrusion 24 a of the pressure-contactingannular body 24 for raising one side of the pressure-contactingannular body 24, the tip thereof being pointed, and a guide groove 33 into which theprotruded 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 thelever supporting part 42 is provided with anoperation 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 asecuring pin 51 with aholding part 52 expanded in the horizontal direction to penetrate therethrough. - In addition, the
operation piece 35 in theoperation lever 31 is configured to be fitted to or removed from theprotruded piece 45 provided on the lowercylindrical 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 theprotruded piece 45 before inserting thesecuring pin 51, theoperation lever 31 is fixed to the lowercylindrical body 41. - As shown in
FIG. 5 , thesecond butting body 5 is disk-shaped on the upper end side, including abutting base body 71 in which a later described supportcylindrical body 72 in the shape of a cylinder is protruded downward; the supportcylindrical body 72 which, being blocked on the upper end side, is fitted into the opening part of thebutting base body 71, and into which the upper end of the second pole is removably loaded; asupport piece 73 which is provided inside of thebutting base body 71; anurging spring 74 which is disposed between thesupport piece 73 and the upper end face of the supportcylindrical body 72; and a buttingauxiliary body 75 which is removably disposed on the side of the upper end face of thebutting 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 thebutting base body 71 is butted against theceiling 62, theurging spring 74 causes thebutting base body 71 to be pressure-contacted with theceiling 62 by the resilience. At this time, the flexibility of the buttingauxiliary body 75 prevents the ceiling surface from being damaged. - Next, the operation of the telescopic prop-
up pole device 1 according to thepresent embodiment 1 will be described. - As shown in
FIG. 1 , the telescopic prop-uppole device 1 according to thepresent embodiment 1 is vertically fixed and disposed between thefloor 61 and theceiling 62 in the prop-up state by vertically erecting thefirst pole 2 on thefloor 61 through thefirst butting body 3, for example, and causing thesecond butting body 5 disposed on the upper end of thesecond pole 4 telescopably jointed to thefirst pole 2 through thetelescoping adjustment body 6 to be pressure-contacted with theceiling 62. At this time, thetelescoping adjustment body 6 is operated as follows. - The tip of the
locking screw 53 is butted against the circumference of thesecond pole 4 through thehole 14 a of the uppercylindrical body 11 and the threadedhole 47 of the lowercylindrical body 41, locking thesecond pole 4. - In addition, as shown in
FIG. 3 , the pressure-contactingannular body 24 in the pole pressure-contacting/releasingpart 21 is disposed on theinclined part 48 of the lowercylindrical 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-contactingannular body 24 being slightly bulged toward the circumference side of one side and the other side of thesecond pole 4 fitted into thefirst pole 2, respectively. - Further, the pressure-contacting
annular body 24 is pressed downward inFIG. 3 by thecoil spring 22 through the internalcylindrical 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 thesecond pole 4, respectively, thus thesecond pole 4 being in the state where it is fixed to thefirst pole 2 through thetelescoping adjustment body 6. - Next, the telescoping operation of the telescopic prop-up
pole device 1 according to thepresent embodiment 1 will be described below. - In order to adjust the protruding length of the
second pole 4 with respect to thefirst pole 2 in the telescopic prop-uppole device 1, the lockingscrew 53 is first turned to remove it, which is followed by operating theoperation piece 35 of theoperation lever 31 inwardly (in the direction of arrow ‘a’ inFIG. 3 ). - Thereby, the pushing-up
piece 32 of theoperation lever 31 is displaced upward around a pivot of the protrudedpiece 13, whereby theprotrusion 24 a of the pressure-contactingannular body 24 is pushed up upward. - As a result of this, as shown in
FIG. 4 , one side of the pressure-contactingannular body 24 and that of the internalcylindrical body 23 are pushed up upward against the resilience of thecoil spring 22, resulting in the pressure-contactingannular 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-contactingannular body 24 are protruded toward the side of the circumference of one side and the other side of thesecond pole 4 fitted into thefirst pole 2 being cancelled, whereby thesecond pole 4 becomes free to be vertically moved, i.e., thesecond pole 4 becomes telescopable with respect to the lower pole, which results in the protruding length of thesecond pole 4 with respect to thefirst 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 theoperation piece 35 constituting theoperation lever 31 will automatically lower the pressure-contactingannular body 24 by the resilience of thecoil spring 22 to allow it to restore the state as shown inFIG. 3 , with theoperation lever 31 also being returned to the position as shown inFIG. 3 under the action of the resilience of thecoil spring 22. - When the telescopic prop-up
pole device 1 is to be packaged or transported, theoperation piece 35 is displaced to a position as shown inFIG. 4 , and the securingpin 51 is utilized to fix theoperation lever 31 to the protrudedpiece 45 for keeping thesecond pole 4 telescopable with respect to thefirst pole 2. This is because, if the pressure-contactingannular body 24 is left to be pressure-contacted with the circumference of thesecond pole 4, there is a possibility that thesecond pole 4 might be deformed by an external impact, resulting in the product having had a flaw, thus it is necessary that thesecond pole 4 be kept telescopable with respect to thefirst pole 2 for prevention of occurrence of a flaw. - With the telescopic prop-up
pole device 1 according to thepresent embodiment 1, simply by making one-touch operation on theoperation piece 35 of theoperation lever 31 in the direction of arrow ‘a’, thesecond pole 4 can be brought into the state where it is telescopable with respect to thefirst pole 2, and the protruding length of thesecond pole 4 is adjustable to a desired length, and simply by canceling the operation force applied to theoperation piece 35 of theoperation lever 31, thesecond pole 4 can be automatically brought into the state where it is fixed with respect to thefirst pole 2. - Therefore, there can be realized and provided a telescopic prop-up
pole device 1 with which the length adjustment of thesecond pole 4 and the fixing of thesecond 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 theoperation lever 31 for pushing up the pressure-contactingannular body 24 or canceling the pushing up is adopted. - In addition, because the
second butting body 5 into which the upper end of thesecond pole 4 is schemed to have a built-inurging spring 74 for pressure contact, with a buttingauxiliary body 75 being provided which is flexibly butted against theceiling 62, there can be realized and provided a telescopic prop-uppole device 1 with which thesecond pole 4 can be positively mounted to theceiling 62 with the ceiling surface being prevented from being damaged. - Next, a telescopic prop-up
pole device 1A according to anembodiment 2 of the present invention will be described with reference toFIG. 6 toFIG. 9 . - For the telescopic prop-up
pole device 1A of thepresent embodiment 2, the same elements as those of the telescopic prop-uppole device 1 of theembodiment 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 andFIG. 7 , the basic configuration of the telescopic prop-uppole device 1A of thepresent embodiment 2 is substantially the same as that of the telescopic prop-uppole device 1 of theembodiment 1. Specifically, the telescopic prop-uppole device 1A of thepresent embodiment 2 is characterized in that, instead of theaforementioned operation lever 31 of turning operation type, anoperation lever 81 of pushbutton type has been adopted, and the geometries of thelever loading part 12 of the uppercylindrical body 11, and thelever supporting part 42 of the lowercylindrical body 41 have been changed to provide alever loading part 12A and alever supporting part 42A which slidably hold theoperation lever 81 of pushbutton type in the direction of arrows ‘b’ and ‘c’ as shown inFIG. 8 , and the other configuration is substantially the same as that of the telescopic prop-uppole device 1 of theembodiment 1. - More specifically, the
operation lever 81 in thepresent embodiment 2 is engaged between thelever loading part 12A in the uppercylindrical body 11, and thelever supporting part 42A formed in the lowercylindrical 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-uppiece 82 which, being located at the distal end thereof, is engaged with the bottom of aprotrusion 24 a of the pressure-contactingannular body 24, the tip thereof being pointed, for pushing up one side of the pressure-contactingannular body 24; a slidingbody 83 which, being located adjacent to the pushing-uppiece 82, slides in the direction of arrows ‘b’ and ‘c’ inside thelever loading part 12A andlever supporting part 42A; and further, apressing button 84 which, being located on the rear end side of the slidingbody 83, is protruded from the protruding ends of thelever loading part 12A andlever supporting part 42A. - The operation of the telescopic prop-up
pole device 1A of thepresent embodiment 2 that has adopted such anoperation lever 81 of pushbutton type will be described with reference also toFIG. 8 andFIG. 9 . - When the telescopic prop-up
pole device 1A which has adopted theoperation lever 81 according to thepresent embodiment 2 is vertically fixed and disposed in the prop-up state between thefloor 61 andceiling 62, the tip of the lockingscrew 53 is butted against the circumference of thesecond pole 4 through thehole 14 a of the uppercylindrical body 11 and the threadedhole 47 of the lowercylindrical body 41, locking thesecond pole 4, in the same manner as shown inFIG. 1 . - At this time, the
telescoping adjustment body 6 and theoperation lever 81 are operated as follows. As shown inFIG. 8 , the pressure-contactingannular body 24 in the pole pressure-contacting/releasingpart 21 is disposed on theinclined part 48 of the lowercylindrical 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-contactingannular body 24 being slightly bulged toward the circumference side of one side and the other side of thesecond pole 4 fitted into thefirst pole 2, respectively. - Further, the pressure-contacting
annular body 24 is pressed downward inFIG. 8 by thecoil spring 22 through the internalcylindrical 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 thesecond pole 4, respectively, thus thesecond pole 4 being in the state where it is fixed to thefirst pole 2 through thetelescoping adjustment body 6. - In addition, the tip of the pushing-up
piece 82 of theoperation lever 81 is engaged with the bottom of theprotrusion 24 a of the pressure-contactingannular body 24, and thepressing button 84 is in the state where it is protruded sideward from the protruding ends of thelever loading part 12A andlever supporting part 42A. - Next, in order to adjust the protruding length of the
second pole 4 with respect to thefirst pole 2 in the telescopic prop-uppole device 1A, the lockingscrew 53 is first turned to remove it, which is followed by pushing in thepressing button 84 in the direction of arrow ‘b’ against the resilience of thecoil spring 22. - Thereby, the pushing-up
piece 82 of theoperation lever 81 pushes upward theprotrusion 24 a of the pressure-contactingannular body 24, and thus as shown inFIG. 9 , one side of the pressure-contactingannular body 24 and that of the internalcylindrical body 23 are pushed up upward against the resilience of thecoil spring 22, resulting in the pressure-contactingannular 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-contactingannular body 24 are protruded toward the side of the circumference of one side and the other side of thesecond pole 4 fitted into thefirst pole 2 being cancelled, whereby thesecond pole 4 becomes free to be vertically moved, i.e., thesecond pole 4 becomes telescopable with respect to the lower pole, which results in the protruding length of thesecond pole 4 with respect to thefirst 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 thepressing button 84 will automatically lower the pressure-contactingannular body 24 by the resilience of thecoil spring 22 to allow it to restore the state as shown inFIG. 8 , with theoperation lever 31 also being displaced in the direction of arrow ‘c’ to be returned to the position as shown inFIG. 8 under the action of the resilience of thecoil spring 22. - With the telescopic prop-up
pole device 1A according to thepresent embodiment 2, simply by making one-touch operation on thepressing pushbutton 84 of theoperation lever 81 of pushbutton type in the direction of arrow ‘b’, thesecond pole 4 can be brought into the state where it is telescopable with respect to thefirst pole 2, and the protruding length of thesecond pole 4 is adjustable to a desired length, and simply by canceling the pressing force applied to thepressing pushbutton 84, thesecond pole 4 can be automatically brought into the state where it is fixed with respect to thefirst pole 2. - Therefore, there can be realized and provided a telescopic prop-up
pole device 1A with which the length adjustment of thesecond pole 4 and the fixing of thesecond 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 theoperation lever 81 for pushing up the pressure-contactingannular 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-uppole device 1A with which thesecond pole 4 can be positively mounted to theceiling 62 through thesecond butting body 5 with the ceiling surface being prevented from being damaged. - Next, a telescopic prop-up
pole device 1B according to anembodiment 3 of the present invention will be described with reference toFIG. 10 . - The telescopic prop-up
pole device 1B according to thepresent embodiment 3 is characterized in that it utilizes the telescopic prop-uppole device 1 of theembodiment 1, and further to the second pole 4 (or the first pole 2), a desired number (two in an example as shown inFIG. 10 ) ofhooks 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-uppole device 1B is the same as that of theembodiment 1. - According to the telescopic prop-up
pole device 1B of thepresent embodiment 3, as is the case with the aforedescribed embodiments, there can be realized and provided a telescopic prop-uppole 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, thesecond pole 4 can be positively mounted to theceiling 62 through thesecond 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-uppole 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 thepresent embodiment 3, the telescopic prop-uppole device 1A in theembodiment 2 can duly be used, with ahook 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. - The telescopic prop-up
