[0010] The antenna stand according to the present invention is characterized in that the detachable part is in the shape of a long rod.

Effect of the Invention

[0011] The antenna stand according to the present invention has a metal detachable part to which the antenna is detachably attached, a metal opening and closing joint part connected to the lower part of the detachable part, and a plurality of metal legs radially extending from the opening and closing joint part, and the legs open and close starting from the opening and closing joint part. Since each member is made of metal, it is robust and particularly excellent in durability when used outdoors. In addition, since the legs open and close, the angle of the legs with respect to the opening and closing adjustment part can be arbitrarily selected, so that the antenna is arranged at a high position from the installation surface, and thus the radio wave reception sensitivity is high.

[0012] The antenna stand according to the present invention has a detachable part including a cylindrical locking part into which the support column part of the antenna is inserted and locked, and a cylindrical cover part that covers the locking part. In a state where the support column part is locked to the locking part, the locking part is covered by the cover part. Since the locking part is covered by the cover part, it becomes impossible to operate the locking part from the outside, so that the support column part of the antenna is prevented from being accidentally removed from the detachable part. Therefore, theft of the antenna is prevented.

[0013] In the antenna stand according to the present invention, a locking part flange piece is formed on the side surface of the locking part, a cover part flange piece is formed on the side surface of the cover part, and the locking part flange piece and the cover part flange piece are connected. By connecting the flange pieces to each other, the cover part remains immovable while covering the locking part, so that the locking part is not accidentally exposed and is prevented from being operated. Therefore, theft of the antenna is prevented.

[0014] The antenna stand according to the present invention has a connecting part at the tip of the leg for connecting to an antenna pedestal that rises upward from the installation surface. By connecting the leg to the antenna pedestal, the antenna is arranged at a higher position by the amount that rises upward from the installation surface. Therefore, the reception sensitivity of radio waves is high.

[0015] The detachable part of the antenna stand according to the present invention is in the shape of a long rod. By using the detachable part, the antenna is arranged at a higher position from the installation surface by an amount corresponding to the length of the detachable part. Therefore, the reception sensitivity of radio waves is high.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, the antenna stand 40 according to an embodiment of the present invention will be described with reference to the drawings. First, the antenna mount 10 to which the antenna stand 40 is attached or detached will be described with reference to the drawings. FIGS. 1 to 7 show the process of deformation of the antenna mount 10, and FIGS. 8 and 9 show the antenna mount 10 supporting an antenna (accurately, what is shown is a tripod, and the antenna is not shown). As shown in FIGS. 1 to 7, the antenna mount 10 deforms from the folded state to the deployed support state, and also deforms from the support state to the folded state. As shown in FIGS. 1 and 2, the antenna mount 10 in the folded state is longitudinal and grouped together, so it can be stored, for example, in a dedicated storage bag (not shown) and can be manually transported. On the other hand, as shown in FIGS. 6 and 7, the antenna mount 10 in the support state stands on the installation surface, so it can support the antenna as shown in FIGS. 8 and 7.

[0018] As shown in FIGS. 1 and 2, the antenna pedestal 10 has three legs 11, three arms 16, a joint portion 21 which is a connecting portion between the legs 11 and the arms 16, a first reinforcing portion 25 (see FIG. 12), and a second reinforcing portion 26 (see FIG. 13). Each leg 11 has a longitudinal rectangular prism shape and is approximately 30 centimeters to 65 centimeters. Preferably, the length of the leg 11 is approximately 54 centimeters. Each arm 16 is also longitudinal and is approximately 70 centimeters to 90 centimeters. Preferably, the length of the arm 16 is approximately 88.2 centimeters. At the upper end of each leg 11, the arm 16 is connected via the joint portion 21, and the arm 16 is disposed between each pair of legs 11. At the lower end of each leg 11, a grounding portion 15 is connected. The grounding portion 15 is formed by two overlapping plate-like pieces, and the two plate-like pieces are fastened at one point. By rotating the second plate-like piece with respect to the first plate-like piece, the grounding portion 15 expands, and the installation area with respect to the installation surface expands (see FIG. 7, the lowermost grounding portion 15). At each joint portion 21, the arm 16 rotates about the joint portion 21, so that it can be freely bent in the lateral direction (horizontal direction). Also, at each joint portion 21, the leg 11 rotates about the joint portion 21, so that it can be freely bent in the longitudinal direction (vertical direction). Each leg 11, each arm 16, and each joint portion 21 are connected by bolts, and can be freely deformed by loosening the bolts and fixed by tightening the bolts.

[0019] The leg 11 is composed of a first leg 12, a second leg 13, and a third leg 14, and the arm 16 is composed of a first arm 17, a second arm 18, and a third arm 19. The joint portion 21 is composed of a first joint portion 22 and a second joint portion 23 that are pre-connected to the leg 11 and the arm 16, and a detachable joint portion 24 that makes the leg 11 and the arm 16 detachable.

[0020] One end of the first arm 17 is connected to the upper end of the first leg 12 via the first joint portion 22, and the other end of the first arm 17 can be connected to the upper end of the third leg 14 via the detachable joint portion 24. The detachable joint portion 24 is pre-connected to the upper end of the third leg 14. One end of the second arm 18 is connected to the upper end of the second leg 13 via the second joint portion 23, and the other end of the second arm 18 is connected to the upper end of the first leg 12 via the first joint portion 22. One end of the third arm 19 is connected to the upper end of the second leg 13 via the second joint portion 23, and the other end of the third arm 19 is connected to the upper end of the third leg 14 via the detachable joint portion 24.

[0021] In the folded state, the other end of the first arm 17 is detached from the detachable joint portion 24, and the first leg 12 and the first arm 17 remain connected. The first leg 12 is bent at the first joint portion 22 and lies horizontally on the installation surface in the lateral direction. The second leg 13 is bent at the second joint portion 23 and lies horizontally on the installation surface in the lateral direction. The third leg 14 is bent at the detachable joint portion 24 and lies horizontally on the installation surface in the lateral direction. The first arm 17 and the second arm 18 are bent at the first joint portion 22 and are close to each other. The second arm 18 and the third arm 19 are bent at the second joint portion 23 and are close to each other. The first leg 12 is close to the first arm 17 and the second arm 18. The second leg 13 is close to the second arm 18 and the third arm 19. The third leg 14 is close to the third arm 19 and the first arm 17. Therefore, in the folded state, the first leg 12, the second leg 13, the third leg 14, the first arm 17, the second arm 18, and the third arm 19 are in a lying state, aligned in generally the same longitudinal direction, and bundled together.

[0022] As shown in FIG. 3, the first arm portion 17 and the second arm portion 18 are deployed by rotating about the first joint portion 22, and the second arm portion 18 and the third arm portion 19 are deployed by rotating about the second joint portion 23. As shown in FIGS. 4 and 5, when the other end of the first arm portion 17 is connected to the third leg portion 14 via the detachable joint portion 24, the first arm portion 17, the second arm portion 18, and the third arm portion 19 are arranged in a triangular shape. The first arm portion 17 extends horizontally across the first leg portion 12 and the third leg portion 14 adjacent to each other, the second arm portion 18 extends horizontally across the first leg portion 12 and the second leg portion 13 adjacent to each other, and the third arm portion 19 extends horizontally across the second leg portion 13 and the third leg portion 14 adjacent to each other.

[0023] In FIGS. 4 and 5, when the first leg portion 12 rotates about the first joint portion 22 and rises vertically, the second leg portion 13 rotates about the second joint portion 23 and rises vertically, and the third leg portion 14 rotates about the detachable joint portion 24 and rises vertically, as shown in FIG. 6, the antenna pedestal 10 is in a supported state. In the supported state, further, the second reinforcing portion 26 is connected across the first arm portion 17 and the first leg portion 12, the second reinforcing portion 26 is connected across the second arm portion 18 and the first leg portion 12, the second reinforcing portion 26 is connected across the second arm portion 18 and the second leg portion 13, the second reinforcing portion 26 is connected across the third arm portion 19 and the second leg portion 13, the second reinforcing portion 26 is connected across the third arm portion 19 and the third leg portion 14, and the second reinforcing portion 26 is connected across the first arm portion 17 and the third leg portion 14. Further, as shown in FIG. 7, the first reinforcing portion 25 is connected across the first arm portion 17 and the second arm portion 18, the first reinforcing portion 25 is connected across the second arm portion 18 and the third arm portion 19, and the first reinforcing portion 25 is connected across the first arm portion 17 and the third arm portion 19.

[0024] As shown in FIGS. 8 and 9, in the antenna pedestal 10 in the supported state, the tripod 5 of the antenna is attached to the upper end of the leg portion 11.

[0025] Incidentally, the first reinforcing portion 25 and the second reinforcing portion 26 are attached to the respective arm portions 16 and are detachable from the arm portions 16. Here, the arm portions 16, the first reinforcing portion 25, and the second reinforcing portion 26 will be described based on the drawings. In FIGS. 10 and 11, the arm portions 16 are shown. In FIG. 12, the first reinforcing portion 25 is shown, and in FIG. 13, the second reinforcing portion 26 is shown.

[0026] As shown in FIG. 10, each of the arm portions 16 is longitudinal and has an L-shaped cross section. A plurality of attachment holes 20 are formed in the arm portions 16, and bolts, nuts, washers, etc. are appropriately attached to the attachment holes 20. The first reinforcing portion 25 is attached to the upper surface of the arm portion 16 and fixed with bolts. The second reinforcing portion 26 is attached to the lower surface of the arm portion 16 and fixed with bolts. Therefore, both the first reinforcing portion 25 and the second reinforcing portion 26 have a width that is the same as or narrower than the width of the arm portion 16.

[0027] As shown in FIG. 12, the first reinforcing portion 25 has a longitudinal flat plate shape, and a plurality of first reinforcing portion attachment holes 27 are formed. As shown in FIG. 13, the second reinforcing portion 26 has a flat plate shape and is twisted, and second reinforcing portion attachment holes 28 are formed at both ends. That is, since the second reinforcing portion 26 is connected to the side surfaces of the respective leg portions 11 and the lower surfaces of the respective arm portions 16, the portion between both ends is twisted.

[0028] One first reinforcing portion 25 is stacked on the upper surface of the arm portion 16, and bolts, etc. are passed through the attachment holes 20 and the first reinforcing portion attachment holes 27. One second reinforcing portion 26 is stacked on the lower surface of one end of the arm portion 16, and one second reinforcing portion 26 is also stacked on the lower surface of the other end. Bolts, etc. are respectively passed through the attachment holes 20 and the second reinforcing portion attachment holes 28. Therefore, one first reinforcing portion 25 and two second reinforcing portions 26 are attached to the arm portion 16.

[0029] As described above, the antenna pedestal 10 is configured. Next, the effects of the antenna pedestal 10 will be described.

[0030] The antenna pedestal 10 configured as described above, in the folded state, at the detachable joint 24, the third leg 14 and the first arm 17 are disengaged, and the respective legs 11 and the respective arms 16 lie on the installation surface, aligned in substantially the same longitudinal direction and bundled together (see Fig. 1), so that it can be carried by manpower. On the other hand, by connecting the third leg 14 and the first arm 17 via the detachable joint 24, and also by rotating the respective legs 11 and the respective arms 16 to a supported state (see Fig. 6), the assembly is simple. Also, in the supported state, since the respective legs 11 are oriented in the vertical direction and stand up with respect to the installation surface, the antenna 1 can be firmly supported at a position higher than the snow accumulation (see Fig. 8). In particular, since the respective legs 11 are approximately 30 centimeters to 65 centimeters, even in a snowy environment, the antenna 1 can be firmly supported at a high position. As described above, since the first arm 17 and the third leg 14 are detached and connected by a single attached bolt at one location (the detachable joint 24), even a person not accustomed to assembly can perform the work with a single tool such as a wrench.

[0031] The first reinforcing part 25 and the second reinforcing part 26 are attached to the respective arms 16 and are detachable from the arms 16. In the folded state, since the first reinforcing part 25 and the second reinforcing part 26 are housed in the respective arms 16, the members are grouped together and do not protrude. In the supported state, the arms 16 are made firm by being connected by the first reinforcing part 25, and the respective arms 16 and the respective legs 11 are made even more firm by being connected by the second reinforcing part 26. That is, since the respective arms 16 and the respective legs 11 restrain each other, they do not accidentally rotate with respect to each other at the respective joints 21. Also, since the length of the arm 16 is approximately 70 centimeters to 90 centimeters, it is easy to carry by manpower.

[0032] In the supported state, since the respective arm portions 16 are arranged in a triangular shape, compared with a rectangular shape or a circular shape, they can stably stand on the installation surface independently and support the antenna 1. Further, the grounding portion 15 formed by overlapping two plate-like pieces expands and spreads, so that it can stably stand on the installation surface independently. The installation surface can rotate three-dimensionally with respect to the respective leg portions 11 to maintain an arbitrary posture, and it is also possible to finely adjust the height with respect to the respective leg portions 11.

[0033] Next, the antenna stand 40 that is attached to and detached from the antenna pedestal 10 will be described with reference to the drawings. FIGS. 14 and 15 show a state in which the antenna stand 40 is attached to the antenna pedestal 10. The antenna stand 40 is used in place of an existing stand (not shown), for example, when an existing stand that is an accessory of the antenna 1 is fragile or when the height of the existing stand is low.

[0034] As shown in FIGS. 14 and 15, the antenna stand 40 has a metal attachment / detachment portion 41 to which the antenna 1 is attached / detached, a metal opening / closing joint portion 47 connected to the lower part of the attachment / detachment portion 41, and three metal stand leg portions 50 radially extending from the opening / closing joint portion 47. Each stand leg portion 50 has a longitudinal rectangular prism shape and opens and closes with the opening / closing joint portion 47 as a starting point. The tip of each stand leg portion 50 has a connecting portion 51 for connecting to the upper end of the leg portion 11 of the antenna pedestal 10. Therefore, when the opened stand leg portions 50 are connected to the leg portions 11 of the antenna pedestal 10, the antenna stand 40 is connected to the antenna pedestal 10. Note that the connecting portion 51 may be provided on the leg portion 11 of the antenna pedestal 10.

[0035] Here, the opening / closing joint portion 47 and the attachment / detachment portion 41 will be described in detail with reference to the drawings. FIGS. 16 and 17 show the opening / closing joint portion 47, and FIGS. 18 to 20 show the attachment / detachment portion 41.

[0036] As shown in FIGS. 16 and 17, the opening / closing joint portion 47 is divided into three parts and has three joint base portions 48. Each joint base portion 48 has a pair of base pieces 49 facing each other, and a stand leg portion 50 is connected between the base pieces 49. A detachable portion 41 is formed on the upper surface of the opening / closing joint portion 47.

[0037] As shown in FIGS. 18 to 20, the strut portion 2 of the antenna 1 is connected to the detachable portion 41. The strut portion 2 has a locking structure. The locking structure is a structure for inserting and removing the hook-shaped portion 3 from the side surface of the strut portion 2. That is, when no external force is applied to the pressing portion 4 integrated with the hook-shaped portion 3, the hook-shaped portion 3 protrudes from the side surface of the strut portion 2, but when the pressing portion 4 is pushed, the hook-shaped portion 3 is received inside the strut portion 2.

[0038] The detachable portion 41 has a cylindrical locking portion 42 into which the strut portion 2 of the antenna 1 is inserted and locked, and a cylindrical cover portion 43 that covers the locking portion 42, as a structure for preventing theft of the antenna 1. A locking hole 45 and a locking portion flange piece 46 are formed on the side surface of the locking portion 42. The hook-shaped portion 3 of the strut portion 2 is locked in the locking hole 45. The locking portion flange piece 46 is a flat plate-shaped piece extending in the vertical direction and protruding outward from the side surface of the locking portion 42. On the other hand, a cover portion flange piece 44 is formed on the side surface of the cover portion 43. The cover portion flange piece 44 is a flat plate-shaped piece extending in the vertical direction and protruding outward from the side surface of the locking portion 42.

[0039] Next, the usage method of the detachable portion 41 will be described. First, the cover portion 43 is passed through the strut portion 2 of the antenna 1. Next, the locking portion 42 is connected to the strut portion 2. Specifically, in the process of inserting the strut portion 2 into the locking portion 42, the hook-shaped portion 3 is pushed by the inner surface of the locking portion 42 and received inside the strut portion 2, and the hook-shaped portion 3 is locked in the locking hole 45 from the inside of the locking portion 42. Finally, the cover portion 43 is lowered along the strut portion 2, and the locking portion 42 is covered by the cover portion 43. The locking portion flange piece 46 and the cover portion flange piece 44 are overlapped, and for example, they are connected by a Nanjing lock (not shown).

[0040] As described above, the antenna stand 40 is configured. Next, the effects of the antenna stand 40 will be described.

[0041] The antenna stand 40 configured as described above is robust because each member is made of metal, and it is particularly excellent in durability when used outdoors. Also, since the stand legs 50 open and close, the angle of the stand legs 50 with respect to the opening / closing joint portion 47 can be arbitrarily selected, so that the antenna 1 is arranged at a high position from the installation surface (see FIG. 15), and thus the radio wave reception sensitivity is high.

[0042] The hooked portion 3 of the support column portion 2 of the antenna 1 is locked to the locking portion 42 of the attachable / detachable portion 41, and since the locking portion 42 is covered by the cover portion 43 of the attachable / detachable portion 41, it becomes impossible to operate the locking portion 42 from the outside, so that the support column portion 2 is prevented from being inadvertently removed from the attachable / detachable portion 41 (see FIGS. 18 to 20). Therefore, theft of the antenna 1 is prevented.

[0043] The locking portion flange piece 46 and the cover portion flange piece 44 are overlapped, and for example, when both are connected by a padlock or the like, the cover portion 43 remains immovable while covering the locking portion 42, so that the locking portion 42 is not inadvertently exposed and is prevented from being operated (see FIGS. 18 to 20). Therefore, theft of the antenna 1 is prevented.

[0044] Since the tip of the stand leg 50 has a connecting portion 51 for connecting to the upper end of the leg 11 of the antenna mount 10, when the opened stand legs 50 are connected to the leg 11, the antenna stand 40 is connected to the antenna mount 10 (see FIG. 14). By connecting the stand legs 50 to the antenna mount 10, the antenna 1 is arranged at an even higher position due to the upward rise from the installation surface. Therefore, the radio wave reception sensitivity is high.

[0045] Next, the antenna stand 140 according to another embodiment will be described with reference to the drawings. FIG. 21 shows the main part of the antenna stand 140. In the following, the configuration different from that of the antenna stand 40 will be mainly described, and the description of the same configuration as that of the antenna stand 40 will be omitted as appropriate.

[0046] As shown in FIG. 21, the antenna stand 140 is different from the antenna stand 40 in that the detachable part 141 is in the shape of a long bar and the hook part 152 is formed on each stand leg 150.

[0047] Since the detachable part 141 is in the shape of a long bar, the position of the antenna 1 becomes relatively high by the length corresponding to the length. For example, when the detachable part 141 has a telescopic structure or a structure in which another bar-shaped member (not shown) is added, the detachable part 141 changes to an arbitrary length.

[0048] The hook part 152 is arranged between the upper end and the lower end of the stand leg 150 and is formed on the back side of the stand leg 150 in a plan view. The hook part 152 is a plate-shaped piece with a hole, a hook, a ring, or the like. A chain, a string, or the like (hereinafter referred to as "chain or the like", not shown) is passed through each hook part 152, and the opening / closing degree of the stand legs 150 changes according to the length of the chain or the like. For example, when the length of the chain or the like is short, the stand legs 150 are close to each other, so the opening / closing degree is narrow. Therefore, the position of the antenna 1 becomes relatively high. On the other hand, when the length of the chain or the like is long, the stand legs 150 are separated from each other, so the opening / closing degree is wide. Therefore, the position of the antenna 1 becomes relatively low.

[0049] According to the detachable part 141 or the stand leg 150, since the antenna 1 is arranged at a high position from the installation surface, the reception sensitivity of the radio wave is high. In addition, the antenna 1 includes, for example, other arbitrary types (not shown) in addition to the antenna 1a and the antenna 1b.

[0050] In another embodiment according to the present invention, the first reinforcing part is attached to the leg. In another other embodiment, the second reinforcing part is attached to the arm part. In another other embodiment, the first reinforcing part is attached to the lower surface of the arm part, and the second reinforcing part is attached to the upper surface of the arm part. In another other embodiment, it does not have the first reinforcing part and / or the second reinforcing part. In another other embodiment, the length of the leg part is arbitrary. Therefore, the length of the leg part is less than 30 centimeters or 66 centimeters or more. The length of the leg part is selected according to the expected snow accumulation amount. In another other embodiment, the number of leg parts and the number of arm parts are arbitrary. Therefore, it has four or more leg parts and arm parts. In another other embodiment, the length of the arm part is arbitrary. Therefore, the length of the arm part is less than 70 centimeters or 91 centimeters or more. The length of the arm part affects the ease of transportation and is affected by factors such as the size of the antenna stand. Therefore, it is selected according to the physique, physical strength, gender of the person carrying it, and the size of the antenna and stand, etc. In another other embodiment, the antenna stand does not have an anti-theft structure. In another other embodiment, the antenna stand does not have a connecting part. Therefore, the antenna stand is not connected to the antenna pedestal and stands independently directly on the installation surface.

[0051] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments. And the present invention can make various design changes without departing from the matters described in the scope of the utility model registration claims.
