Description

[Technical Field]

[0001] The present invention relates to a pole fixing device and an attachment for an item that handles a fixed pole, which reduces the number of parts, simplifies the configuration, and reduces weight, and which firmly fixes the pole by strongly pressing a ceiling pressing plate against the ceiling surface, allowing the upright fixed pole to be handled and various daily necessities to be easily attached. [Background technology]

[0002] For example, a support post fixing device for fixing both ends of a support post by abutting them against the ceiling surface and the floor surface may include a receiving member that can abut against the ceiling surface arranged at the upper end of the support post, an adjusting member that can abut against the floor surface arranged at the lower end of the support post, the receiving member having a ceiling abutment plate that can be attached to the ceiling surface, a shaft that protrudes downward from the underside of the ceiling abutment plate, a stop plate fixed to the lower end of the shaft, and the stop plate arranged so as to be engageable with the inner surface of the upper end of the support post, and a locking piece with a substantially inverted U-shaped cross section arranged at the bottom of the shaft, which is arranged so as to be engageable with the inner surface of the upper part of the support post, and the locking piece A coil spring is attached to the shaft above the locking piece, and the elasticity of the coil spring urges the locking piece downward, while the adjustment member has a base that can be attached to the floor surface, a bolt is erected on the base base, a nut is screwed onto the bolt, and the support plate directly above it and the locking piece with an approximately U-shaped cross section are arranged so that they can be supported, and by screwing the nut, the support plate and strut of the adjustment member are moved upward to compress the coil spring, and the elasticity of the coil spring presses the ceiling contact plate against the ceiling surface, and at the same time presses the base against the floor surface (see, for example, Patent Document 1).

[0003] However, this support pillar fixing device has a large number of parts and a complex configuration, making it difficult to manufacture. In addition, it is difficult to position the ceiling support plate and base on a vertical line, which can easily lead to the support pillar falling over due to misalignment.

[0004] To solve this problem, there is a column structure that has an upper support that accommodates the upper end of the column and a lower support that accommodates the lower end of the column, each of which has a recessed hole that accommodates the upper or lower end of the column, a spring placed in the bottom of the recessed hole on the upper end side, and the width of each recessed hole in the direction away from the indoor wall surface being approximately 10% wider than the width of the column in the direction away from the indoor wall surface, so that the column is positioned at an angle, and when a rotational force that would cause the column to fall over acts on it due to an earthquake or the like, the column can be prevented from falling over and can be firmly fixed in place compared to when the column is fixed upright (see, for example, Patent Document 2).

[0005] However, this type of column structure has the problem that it is not possible to adequately prevent the columns from falling over when subjected to shaking or impacts such as those caused by an earthquake, and it is difficult to adjust the reaction forces received from the floor and ceiling.

[0006] To solve such problems, a column fixing device is provided which is equipped with a ceiling presser that is pressed against the ceiling, a column presser that is pressed against a temporary column, and a link mechanism that is arranged between the ceiling presser and the column presser and has a link, and that widens or narrows the gap between the ceiling presser and the column presser according to the moment applied to the link, and further equipped with an elastic body that is connected to the link and generates an elastic force according to the magnitude of the deformation when elastically deformed, and an elastic deformation setting unit that sets the magnitude of the elastic deformation of the elastic body so that an elastic force is generated in the direction in which the moment is applied to the link, and the elastic body generates an elastic force according to expansion and contraction. There is a column fixing device in which the elastic deformation setting section has an elastic body connecting member that is connected to the elastic body together with the link, and a member holding section that holds the elastic body connecting member so that the connection point with the elastic body can be set to any one of a plurality of positions along the direction in which a moment is applied to the link, and the member holding section is arranged to extend along the direction in which a moment is applied to the link, and has a male screw that is screwed into the female screw of the elastic body connecting member, and a male screw support section that supports the male screw so that it can rotate while maintaining a fixed position, and the reaction force received from the floor and ceiling is adjusted in accordance with the rotation of the male screw (see, for example, Patent Document 3).

[0007] However, this pillar fixing device has a large number of parts, a complex configuration, and is difficult to manufacture. In addition, the surface area of the ceiling pressing body is small, so the contact force of the ceiling pressing body against the ceiling surface is weak, making it difficult to firmly fix the pillar.

[0025] 1 to 6, reference numeral 1 denotes a support pillar that stands vertically between a floor surface 2 and a ceiling surface 3. In this embodiment, support pillar 1 is made of a wooden block timber with a horizontally long rectangular cross section (38 mm x 89 mm). A box-shaped support pillar 4 is disposed at the lower end of support pillar 1, and a ceiling presser 5 is disposed at the upper end of support pillar 1.

[0026] The column holder 4 is composed of a flat metal base plate 6 that can be installed on the floor surface 2, and a horizontally long rectangular metal box-shaped column holder frame 7 that is connected to the base plate 6 by caulking or welding. The column holding frame 7 is formed in a box shape that can accommodate the lower end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, so that it can accommodate errors in the processing dimensions of the column 1 and subsequent expansion, contraction, warping, and twisting.

[0027] A pair of large dial knobs 8, 8 are rotatably attached to one side of the column holding frame 7, and the end of the inner screw shaft 9 is pressed against the side of the lower end of the column 1, making it possible to fix the lower end of the column 1. The ceiling pressing body 5 is composed of a metal box-shaped column mounting frame 10 and a metal, generally plate-shaped ceiling pressing plate 11 that can be pressed against the ceiling surface 3. A pantograph mechanism 12 is disposed between these, and the ceiling pressing plate 11 can be raised and lowered by rotating a dial knob 13 on the side of the pantograph mechanism 12.

[0028] The pillar mounting frame 10 is formed in a box shape that can accommodate the upper end of the pillar 1, and its shape dimensions are formed to be larger than the cross-sectional shape of the pillar 1, similar to the pillar holding frame 7, so that it can accommodate errors in the processing dimensions of the pillar 1 and subsequent expansion, contraction, warping, and twisting. The ceiling pressure plate 11 is formed in a horizontally elongated rectangular shape, and its shape is formed to be larger than the cross-sectional area of the pillar mounting frame 10, with the length and width dimensions increased by approximately 10% outside the cross-sectional area, and the length and width dimensions increased by approximately 13 to 15% compared to conventional similar ceiling pressure plates.

[0029] A pair of oblong rectangular holes 14 are formed in the middle of the ceiling pressure plate 11, and these holes 14 function as so-called material stealers, reducing the weight of the ceiling pressure plate 11 by an amount equivalent to the area of the holes 14, 14, and reducing the contact area or pressing area of the ceiling pressure plate 11 with the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, thereby increasing the reaction force or stress on the ceiling surface 3.

[0030] The pantograph mechanism 12 has a pair of first links 15 and second links 16 arranged diagonally so as to be able to intersect with each other, and upper and lower ends of the links 15, 16 are rotatably connected via pins 17-20. Of these, pin 17 is hung at a fixed position between the side surfaces of the pillar mounting frame 10, pin 18 is formed with a large diameter and has small diameter sections 18a at both ends slidably disposed in elongated guide grooves 21, 21 formed on the side surfaces of the pillar mounting frame 10, pin 19 is hung at a fixed position between bent pieces 22, 22 that are bent downward at the outer opening edges of the long holes 14, 14, and pin 20 is slidably disposed in elongated guide grooves 23, 23 formed in the other bent piece 22, 22. In the figures, 24 is a pivot pin that pivots the intersection of the first and second links 15, 16 so that they can rotate.

[0031] The pillar mounting frame 10 has elongated slots 25, 25 formed in the middle of both horizontally long sides thereof, with the upper opening edges bent inward so that the upper end of the pillar 1 can abut against the bent edges 26, 26. A pair of large dial knobs 27, 27 are rotatably attached to one side of the pillar mounting frame 10, and the end of the inner screw shaft 28 is pressed against the side of the upper end of the pillar 1, making it possible to fix the upper end of the pillar 1.

[0032] A jack screw 29 coaxial with the dial knob 13 is arranged inside the column mounting frame 10, and the jack screw 29 intersects with the large diameter pin 18 and is screwed in, with its threaded shaft extended and screwed into a fixing nut 30. Then, the dial knob 13 is rotated, and the jack screw 29 is simultaneously rotated and screwed into the pin 18. The pin 18 is pulled to the upper right in FIG. 1 following the rotational displacement of the jack screw 29, and its small diameter portion 18a moves along the guide grooves 21, 21, allowing the first and second links 15, 16 to be raised or lowered. That is, the first and second links 15, 16 can be tilted and displaced by rotating the dial knob 13 to the right or left.

[0033] In this case, in the embodiment of FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15, 16 are tilted. However, if an upright displacement is desired instead of a tilted displacement, the pin 18 can be configured to be capable of following the rotational displacement of the dial knob 13, and the pin 18 can be moved to the left in FIG. 1 along the guide grooves 21, 21. In addition, reference numeral 31 in the figure denotes a rubber plate glued onto the ceiling pressing plate 11, which is made up of separate parts that are glued together to prevent marks from being pressed against the ceiling surface 3 and also to increase the friction of the ceiling pressing plate 11, allowing it to be pressed firmly and reliably against the ceiling surface 3.

[0034] The pole fixing device configured in this way is a pole holding device. body The floor requires a ceiling support 4, a ceiling push-in body 5, and a support 1, all of which must be manufactured. Of these, a specific piece of wood is selected for the support 1, and it is cut to a specific length and with a specific cross-sectional shape according to the distance between the floor surface 2 and the ceiling surface 3. Also, pillar retention body 4 is composed of a flat metal base plate 6 that can be placed on the floor surface 2, and a horizontally long rectangular metal box-shaped column holding frame 7 that is connected to the base plate 6 by caulking or welding.

[0035] The column holding frame 7 is formed into a box shape made of steel plate that can accommodate the lower end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, so that it can accommodate errors in the processing dimensions of the column 1 and subsequent expansion, contraction, warping, and twisting. A pair of large dial knobs 8, 8 are rotatably attached to one side of the column holding frame 7, and the end of the inner screw shaft 9 is pressed against the side of the lower end of the column 1, making it possible to fix the lower end of the column 1.

[0036] The ceiling pressing body 5 is composed of a metal box-shaped column mounting frame 10 and a metal, approximately plate-shaped ceiling pressing plate 11 that can be pressed against the ceiling surface 3, with a pantograph mechanism 12 placed between them, and by rotating a dial knob 13 on the side of the pantograph mechanism 12, the ceiling pressing plate 11 can be raised and lowered.

[0037] The column mounting frame 10 is formed in a box shape capable of accommodating the upper end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, similar to the column holding frame 7, so that it can accommodate errors in the processing dimensions of the column 1 and subsequent expansion / contraction, warping and twisting. The ceiling pressing plate 11 is formed into a horizontally long rectangle, and its shape dimensions are formed to be larger than the cross-sectional area of the column mounting frame 10, and the length and width dimensions are formed to be approximately 10% larger outside the cross-sectional area, and the length and width dimensions are formed to be approximately 13 to 15% larger than those of a conventional similar ceiling pressing plate.

[0038] A pair of oblong rectangular holes 14 are formed in the middle of the ceiling pressing plate 11, and the holes 14 function as so-called material stealers, reducing the weight of the ceiling pressing plate 11 by an amount equivalent to the area of the holes 14, 14, and reducing the contact area or pressing area of the ceiling pressing plate 11 with the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, making it possible to increase the reaction force or stress on the ceiling surface 3.

[0039] Each pair of first link 15 and second link 16 of the pantograph mechanism 12 is disposed obliquely so as to be able to cross each other. Of these, pin 17 is hung at a fixed position between the side surfaces of the pillar mounting frame 10, and pin 18 is formed with a large diameter, with small diameter portions 18a at both ends thereof slidably positioned in elongated guide grooves 21, 21 formed on the side surfaces of the pillar mounting frame 10.

[0040] The pin 19 is placed in a fixed position between two bent pieces 22, 22 that are bent downward at the outer opening edges of the long holes 14, 14, and the pin 20 is slidably disposed in elongated guide grooves 23, 23 formed in the other bent piece 22, 22. The intersecting portion of the first and second links 15, 16 is pivotally mounted by a pivot pin 24 so as to be rotatable.

[0041] Long, narrow slots 25, 25 are formed in the middle of both horizontally long sides of the column mounting frame 10, and the upper opening edges are bent inward so that the upper end of the column 1 can abut against the bent edges 26, 26. A pair of large dial knobs 27, 27 are rotatably attached to the lower part of one side of the pillar mounting frame 10, and the end of the inner screw shaft 28 is pressed against the side of the upper end of the pillar 1, making it possible to fix the upper end of the pillar 1.

[0042] A jack screw 29 coaxial with the dial knob 13 is arranged inside the column mounting frame 10, and the jack screw 29 is supported rotatably at a fixed position. The jack screw 29 is screwed in by intersecting with the large-diameter pin 18, and its screw shaft is extended and screwed into a fixing nut 30. Then, the dial knob 13 is rotated, and the jack screw 29 is simultaneously rotated and screwed into the pin 18. The pin 18 is pulled to the right in FIG. 1 in response to the rotational displacement of the jack screw 29, and its small diameter portion 18a moves along the guide grooves 21, 21, allowing the first and second links 15, 16 to be raised or lowered. That is, the dial knob 13 is rotated to the right or left, so that the first and second links 15, 16 can be tilted and displaced.

[0043] In this case, in the embodiment of FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15, 16 are tilted, but if an upright displacement is required instead of a tilting displacement, the pin 18 is caused to follow the rotational displacement of the dial knob 13, and the pin 18 is moved to the left in FIG. 1 along the guide grooves 21, 21. A rubber plate 31 is adhered onto the ceiling pressing plate 11, and each part of the rubber plate 31 is divided and adhered to prevent the occurrence of pressing marks on the ceiling surface 3, and also increases the friction of the ceiling pressing plate 11, making it possible to press it firmly and surely against the ceiling surface 3.

[0044] In this way, the ceiling pressing plate 11 is formed into a horizontally elongated rectangle, and its shape dimensions are made larger than the cross-sectional area of the pillar mounting frame 10, and the length and width dimensions are increased by approximately 10% outside of the cross-sectional area, making it larger by approximately 13 to 15% than conventional similar ceiling pressing plates.

[0045] A pair of oblong rectangular holes 14 are formed in the middle of the ceiling pressing plate 11, and the holes 14 function as so-called material stealers, reducing the weight of the ceiling pressing plate 11 by an amount equivalent to the area of the holes 14, 14, and reducing the contact area or pressing area of the ceiling pressing plate 11 with the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, thereby making it possible to increase the reaction force or stress on the ceiling surface 3. In addition, the divided components of the rubber plate 31 are adhered to the ceiling pressing body 5, which increases the friction, and there is no need to incorporate a spring into the pillar mounting frame 10 as in the past, so the structure is simpler and can be easily manufactured.

[0046] When using the column holder 4, ceiling presser 5, and column 1 manufactured in this manner to fix the column 1 vertically between the floor surface 2 and the ceiling surface 3, for example, a plumb line is hung from a predetermined position on the ceiling surface 3 where the column 1 is fixed, and the column holder 4 is placed on the corresponding floor surface 2. Then, the lower end of the support 1 is placed in the support frame 7 of the support body 4, and the dial knobs 8, 8 are rotated to press the end of the screw shaft 9 against the side of the lower end of the support 1, thereby fixing the lower end of the support 1 in place.

[0047] In this case, the dial knobs 8, 8 are formed large, which allows for easy rotation and simple fixing of the support 1. Also, the box-shaped dimensions of the support frame 7 are formed larger than the cross-sectional shape of the support 1, so it can quickly accommodate errors in the processing dimensions of the wooden support 1, as well as any subsequent expansion, contraction, warping, or twisting.

[0048] Next, the support column 1 is held upright in the column holding frame 7, and the box-shaped column mounting frame 10 is fitted onto the upper end of the support column 1, and the upper end of the frame is held in contact with the bent pieces 26, 26. Thereafter, the dial knobs 27, 27 are rotated to press the ends of the threaded shafts 28, 28 against the side of the upper end of the support 1, thereby fixing the upper end of the support 1. In this state, the support 1 is temporarily held in an upright position between the support frame 7 and the support mounting frame 10.

[0049] In addition, the dial knobs 27, 27 are large, which allows for easy rotation and simple fixing of the support 1. Moreover, the box-shaped dimensions of the support frame 10 are larger than the cross-sectional shape of the support 1, so it can quickly accommodate errors in the machining dimensions of the wooden support 1, as well as any subsequent expansion, contraction, warping, or twisting.

[0050] Under these circumstances, the dial knob 13 is rotated to start the pantograph mechanism 12 and raise or lower the ceiling pressure plate 11. For example, the dial knob 13 is rotated to the right, which moves the jack screw 29 in unison, pulling the pin 18 to the upper right in FIG. 1 in response to the rotational displacement of the jack screw 29, moving the small diameter portion 18a along the guide grooves 21, 21 and raising or lowering the first and second links 15, 16. In the embodiment shown in FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15 and 16 are tilted and displaced.

[0051] In this case, when the dial knob 13 is to be turned upright instead of tilted, the pin 18 is caused to follow the rotational displacement of the dial knob 13, and the pin 18 is moved along the guide grooves 21, 21 to the left in FIG.

[0052] In this way, when the first and second links 15, 16 are displaced upright and the ceiling pressure plate 11 is pressed against the ceiling surface 3, the contact surface pressure gradually increases and acts as a reaction force on the ceiling surface 3. As a result, the upper end of the support 1 is fixed to the ceiling surface 3, and the support 1 is fixed in an upright position between the ceiling surface 3 and the floor surface 2.

[0053] In this case, the ceiling pressing plate 11 is formed larger than the cross-sectional area of the pillar mounting frame 10, and is formed outside the pillar mounting frame 10 with its length and width dimensions increased by approximately 10%, making it larger than a conventional ceiling pressing plate of the same type with its length and width dimensions increased by approximately 13 to 15%.As a result, the contact area or pressing area with respect to the ceiling surface 3 is increased, and the reaction force is increased, firmly fixing the pillar 1. Furthermore, the ceiling pressing plate 11 has long holes 14, 14 formed in the middle, which reduce the contact area or pressing area with the ceiling surface 3 by an amount equivalent to the area of these holes, thereby increasing the reaction force or stress against the ceiling surface 3 and firmly fixing the support 1.

[0054] The pole 1 thus erected and fixed can be handled, and a hook holder 32 attached to the desired position, and then processed or welded to it as appropriate, so that various daily necessities can be easily hung and used. That is, Figures 7 to 23 show a second embodiment of the present invention, and the same reference numerals are used for components corresponding to those of the above-mentioned embodiment. Of these, Figures 7 to 9 show a hook holder 32 that is attached to an upright fixed support 1, and a pair of hook arms 37, 37 that are attached to both sides of the hook holder 32 to clamp and hold the support 1, and these are used in each of the specific examples in Figures 10 to 23.

[0055] The hook holder 32 comprises a holder body 33 that is attached to the peripheral surface of the support pole 1 at an appropriate position, and hook fittings 34 that are attached to both sides of the body 33. The holder body 33 is made of steel plate formed into a horizontally elongated rectangle or square, and the upper and lower edges are bent inward to form hook rails 35, 36 with a substantially U-shaped cross section, and both ends of the hook fittings 34, 34 are slidably inserted into the hook rails 35, 36.

[0056] The hook fittings 34 are made of steel wire of an appropriate diameter, in this embodiment a steel wire with a diameter of 8 mm, and have hook arms 37, 37 bent and formed at the upper and lower ends thereof in a U-shape when viewed from above.The pair of hook arms 37, 37 are positioned on either side of the support 1, and the distance between them can be adjusted so that both sides of the support 1 can be clamped and held. A nut 38 is fixed to the front center of the holder body 33 , and a large knob 39 and a threaded shaft 40 coaxial with the nut 38 are screwed into the nut 38 , so that the end of the shaft can be pressed against the circumferential surface of the support 1 . In this case, it is desirable to fix a nut (not shown) onto the back surface of the holder body 33, into which the screw shaft 40 can be screwed, place a large-diameter circular pressing plate on the outside of the nut, fix another nut (not shown) onto which the screw shaft 40 can be screwed onto one side of the pressing plate, and arrange the pressing plate so that it can be pressed against the circumferential surface of the support 1, thereby preventing the formation of pressing marks on the support 1 by the screw shaft 40.

[0057] 10 to 12 show a first specific example of an attachment tool for an article in which the second embodiment is applied to attaching to a helmet. The hook holder 32 is fixed to the support 1 using the hook arms 37, 37 and the knob 39, and a helmet holder 41 is attached in an upright position to the front of the holder body 33, so that a helmet 42 can be hung on the upper end of the holder 41. The helmet holder 41 is made by forming a steel wire into an inverted U-shape, with its curved portion 41a allowing a helmet 42 to be hung on it, its lower end bent at a right angle to form a pair of holder legs 43, 43, its tip bent downward to form hook portions 43a, 43a, and a pair of hanging holes 44, 44 formed in advance in the upper front part of the holder body 33.

[0058] Then, the hook holder 32 is fixed to the desired position on the support pole 1, and the hook portions 43a, 43a of the helmet holder 41 are inserted into the latch holes 44, 44 on the front surface of the holder body 33, and the helmet holder 41 is attached in an upright position. After the helmet holder 41 is attached, its curved portion 41a is positioned at the front upper end of the support pole 1, and the helmet 39 is hung on this curved portion 41a for use. This usage state is as shown in FIG.

[0059] 13 to 15 show a second specific example in which the second embodiment is applied to mounting on a bicycle. A hook holder 32 is fixed to the support post 1, and the middle part of a bicycle holder 45 is pre-welded and attached horizontally to the upper front part of the holder body 33. The holder 45 has roughly U-shaped hook portions 46, 46 at both ends of the front of the holder 45, to which a bicycle 47, or in this embodiment the top frame (tube) 48 of a mountain bike, can be hooked.

[0060] The bicycle holder 45 is made of straight steel wire, with a roughly U-shaped bent section 49 formed in the center of the straight section 48, and both ends of the straight sections 48, 48 are bent at right angles, with roughly U-shaped hook sections 46, 46 formed upward at the tips, allowing the top frame (tube) 48 to be hooked onto the hook sections 46, 46. Then, the hook holder 32 is fixed to the desired position on the support pole 1, and the bicycle holder 45 is fixed to the upper front surface of the holder body 33, with the hook portions 46, 46 facing upward to attach the bicycle holder 45.

[0061] After the bicycle holder 45 is installed, the top frame (tube) 48 is hooked onto the hook portions 46, 46, allowing for easy installation and removal of the bicycle 47. This usage is shown in Figure 15. In this case, the top frame (tube) 48 is hooked to the hook portions 46, 46 with a sufficient margin, so that the bicycle 47 is hooked to the support pole 1 in a forward-leaning position, but as mentioned above, the ceiling pressing plate 11 presses firmly against the ceiling surface 3, firmly fixing the support pole 1 and stably supporting the forward-leaning position of the bicycle 47.

[0062] 16 to 18 show a third specific example in which the second embodiment is applied to attachment to a school bag or a backpack. A hook holder 32 is fixed to the support 1, and a school bag or backpack holder 50 is attached horizontally to the upper front part of the holder body 33. The roughly U-shaped hook portions 51, 51 at both ends of the holder 50 can be used to hook the school bag 52 or backpack, or in the third specific example, the shoulder strap 53 of the school bag 52. The school bag or backpack holder 50 is made by folding a steel wire approximately in half, forming approximately U-shaped hook portions 51, 51 at both ends, and bending both ends of the steel wire downward to provide an insertion shaft 54 protruding downward.

[0063] Then, the hook holder 32 is fixed at the desired position on the support pole 1, and the insertion shafts 54, 54 are inserted into the side edges at both ends of the upper front surface of the holder body 33, and the school bag holder 50 is held horizontally by the bending elasticity when inserted. In this case, it is also possible to fix the insertion shafts 54, 54 by welding them to the front surface of the hook holder 32. This situation is shown in Figure 17. After the school bag holder 50 is attached, it has U-shaped hooks 51, 51 on both sides that protrude outward from the sides of the support pole 1, and the school bag 52 can be easily attached by hooking the shoulder straps 53, 53 of the school bag 52 onto these hooks 51, 51. A backpack can be attached in the same way. This usage is shown in Figure 18.

[0064] 19 to 21 show a fourth example in which the second embodiment is applied to the installation of a guitar. The hook holder 32 is fixed to the support 1 at an appropriate height, and the rear end of the holder case 54 of the guitar holder 55 is welded to the upper end of the center of the front of the holder body 33, with the front part of the holder case 54 being attached so that it protrudes horizontally. A nut 56 is welded to the front end of the holder case 54, and an attachment screw 57 of the guitar holder 55 is screwed into the screw hole to secure it in place. A roughly U-shaped hook portion 58 is welded to the front end of the attachment screw 57 and attached.

[0065] The hook portion 58 is formed in a bifurcated shape, and the tips of the pair of hook arms 59, 59 are formed to be inclined upward, so that the head portion 61 of the guitar 60 can be hooked onto these hook arms 59, 59. Therefore, when the guitar 60 is not in use, the head portion 61 is hooked on the hook arms 59, 59 and supported vertically, allowing for safe storage in a compact storage space, and when in use, the head portion 61 is removed from the hook arms 59, 59.

[0066] 22 to 24 show a fifth example of a multipurpose device in which the second embodiment is applied to the attachment of a shoulder bag and a cap. A hook holder 32 is fixed to the support 1, and the rear ends of a pair of bag or cap holders 62 are rotatably attached to the upper front surface of the holder body 33, and are attached so as to be able to rotate freely around the rear ends, and shoulder bags 63 and caps 64 can be hooked onto the tip ends of these holders.

[0067] The bag or cap holder 62 is made by forming a steel wire into a straight line, the rear end of the straight line being bent at a right angle, and the bent portion 65 can be inserted into an insert pipe 66 welded vertically to the front surface of the holder body 33, and the front end of the straight line is gently inclined upward to form a hook portion 67. In the drawing, 68 is a rubber or resin tube attached to the straight portion, and 69 is a rubber or resin tube attached to the hook portion 67.

[0068] Then, the holder body 33 is attached to the desired position of the support 1, multiple insert pipes 66 are attached to the front of the holder body 33, the rear end of the bag or cap holder 62 is inserted into the insert pipe 66, and it is attached so that it can rotate around the rear end, and the hook part 67 is placed at the tip of the insert pipe 66 facing upward. Therefore, the shoulder bag 63 or the cap 64 is hooked onto these hook portions 67. This state is shown in Figure 24, and when in use, the shoulder bag 63 or the cap 64 is simply hooked onto the hook portion 67 or removed. [Industrial Applicability]

[0069] The pole fixing device of the present invention reduces the number of parts, simplifies the configuration, and reduces weight, and also increases the pressing area of the ceiling pressing plate, which presses the ceiling pressing plate strongly against the ceiling to firmly fix the pole.Furthermore, the attachment tool for items that handle the fixed pole can handle the upright fixed pole and easily attach various daily necessities, for example, thereby improving convenience.
