Description

Technical Field

[0001] The present invention relates to a mount for an antenna.

Background Art

[0002] Conventionally, in disaster-stricken areas where communication networks have been cut off due to emergencies such as disasters, simple antennas are installed for relaying radio waves transmitted and received by wireless communication devices such as mobile phones to base stations and the like. When roads or railways are blocked due to natural disasters or accidents, transportation means cannot be used, so it is necessary to manually transport the simple antenna to the disaster-stricken area. For example, the antenna supporting mount described in the following Patent Document 1 (hereinafter referred to as "the first known invention from the literature") has a structure in which three support legs extend radially from the stand main body and the support legs are detachable, so that disassembly facilitates manual transportation.

Summary of the Invention

Problem to be Solved by the Invention

[0004] However, when a mount like the above-mentioned first known invention from the literature is used in a disaster-stricken area, for example, in a heavy snowfall area, it needs to be stably installed even in a deep snow environment to ensure an environment where the antenna can function. Additionally, in disaster-stricken areas, work is not necessarily performed by persons accustomed to installing such mounts, so a structure that can be easily assembled by anyone is preferable.

[0005] The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide an antenna mount that is robust and easy to assemble.

Means for Solving the Problem

[0006] To achieve the above objective, the antenna mount according to the present invention comprises a plurality of legs and arms connected to the upper ends of the legs and connecting the legs to each other, and positioned between each of the legs, wherein the connection portion between the legs and the arms becomes a joint, thereby transforming into a supported state that enables the antenna to be supported at the upper ends of the legs, or into a folded state that enables it to be folded and transported, wherein one of the joints is a detachable joint that allows the legs and the arms to be attached to each other, and in the supported state, the legs and arms are connected at the detachable joint, the legs stand upright, and the arms extend horizontally between adjacent legs, and in the folded state, the legs and arms are detached at the detachable joint, the legs bend at the joint and are directed horizontally, and the arms bend at the joint and move closer to each other.

[0007] The antenna mount according to the present invention is characterized in that the arm portion has a first reinforcing portion that connects the arm portions to each other in the supported state.

[0008] The antenna mount according to the present invention is characterized in that the arm portion has a second reinforcing portion that connects the arm portion and the leg portion in the supported state.

[0009] The antenna mount according to the present invention is characterized in that the first reinforcing part is attached to the upper surface of the arm and is detachable, and the second reinforcing part is attached to the lower surface of the arm and is detachable.

[0010] The antenna mount according to the present invention is characterized in that the length of the legs is 30 centimeters to 65 centimeters.

[0011] The antenna mount according to the present invention comprises an arm section composed of a first arm section, a second arm section, and a third arm section, a leg section composed of a first leg section, a second leg section, and a third leg section, one end of the first arm section connected to the first leg section, the other end of the first arm section detachably attached to the third leg section, one end of the second arm section connected to the second leg section, the other end of the second arm section connected to the first leg section, one end of the third arm section connected to the second leg section, and the other end of the third arm section connected to the third leg section. In the supported state, the other end of the first arm is connected to the third leg, so that the first arm, the second arm, and the third arm are arranged in a triangular shape. In the folded state, the other end of the first arm is detached from the third leg, so that the first arm and the second arm are close together, the second arm and the third arm are close together, the first leg is close together to the first arm and the second arm, the second leg is close together to the second arm and the third arm, and the third leg is close together to the third arm. [Effects of the Invention]

[0012] The antenna mount according to the present invention has a plurality of legs and arms connected to the upper ends of the legs to connect the legs to each other, and positioned between each leg. The connection points between the legs and arms become joints, allowing the mount to transform into a supported state that supports an antenna at the upper ends of the legs, or into a folded state that allows it to be folded and transported. One joint is a detachable joint that allows the legs and arms to be attached and detached. In the supported state, the legs and arms are connected at the detachable joint, the legs stand upright, and the arms extend horizontally between adjacent legs. In the folded state, the legs and arms are detached at the detachable joint, the legs bend at the joint to face horizontally, and the arms bend at the joint to move closer together. The legs and arms are connected at the detachable joint, and the supported state is achieved by rotating the legs and arms, making assembly easy. Furthermore, because the legs are oriented vertically, they stand upright relative to the mounting surface, allowing the antenna to be securely supported at a height higher than the snow accumulation, even in deep snowy environments. On the other hand, in the folded state, the legs and arms detach at the detachable joints, and each leg and arm is oriented horizontally, allowing them to be bundled together for transport. As described above, the transformation is possible by detaching the arms and legs at a single point (the detachable joint), making assembly simple.

[0013] The antenna mount according to the present invention has arm sections that are connected to each other in the supported state by a first reinforcing section. In the supported state, the connection of the arm sections makes it robust.

[0014] The antenna mount according to the present invention has an arm portion that has a second reinforcing portion that connects the arm portion and the leg portion when in a supported state. When in a supported state, the connection between the arm portion and the leg portion makes it robust.

[0015] The antenna mount according to the present invention has a first reinforcing part that is attached to the upper surface of the arm and is detachable, and a second reinforcing part that is attached to the lower surface of the arm and is detachable. When folded, the first and second reinforcing parts are housed in the arm, so the components are bundled together and do not take up much space.

[0016] The antenna mount according to the present invention has legs that are 30 to 65 centimeters long. Therefore, even in snowy environments, the antenna can be securely supported at a height higher than the snow cover.

[0017] The antenna mount according to the present invention has an arm section composed of a first arm section, a second arm section, and a third arm section, and a leg section composed of a first leg section, a second leg section, and a third leg section, one end of the first arm section is connected to the first leg section, the other end of the first arm section is detachably attached to the third leg section, one end of the second arm section is connected to the second leg section, the other end of the second arm section is connected to the first leg section, one end of the third arm section is connected to the second leg section, and the other end of the third arm section is connected to the third leg section, and in the supported state, the other end of the first arm section is connected to the third leg section, so that the first arm section, the second arm section, and the third arm section are arranged in a triangular shape, and in the folded state, the other end of the first arm section is detached from the third leg section, the first arm section and the second arm section are close together, the second arm section and the third arm section are close together, the first leg section is close together to the first arm section and the second arm section, the second leg section is close together to the second arm section and the third arm section, and the third leg section is close together to the third arm section. In its supported state, the arms are arranged in a triangular shape, allowing it to stand stably on the surface and support the antenna more securely compared to a square or circular shape. On the other hand, in its folded state, the arms and legs can be bundled together in close proximity, making it transportable. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0019] Hereinafter, an antenna stand 10 according to an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 7 show the process of deformation of the antenna stand 10 according to this embodiment, and Figures 8 and 9 show the antenna stand 10 supporting an antenna (more precisely, what is shown is a tripod, and the antenna is not shown). As shown in Figures 1 to 7, the antenna stand 10 can be transformed from a folded state to an unfolded support state, and also from the support state to a folded state. As shown in Figures 1 and 2, the folded antenna stand 10 is longitudinal and can be bundled into a single unit, so it can be stored in a dedicated storage bag, etc. (not shown), and can be transported by hand. On the other hand, as shown in Figures 6 and 7, the antenna stand 10 in the support state is self-supporting on the installation surface, so it can support an antenna, as shown in Figures 8 and 7.

[0020] As shown in Figures 1 and 2, the antenna mount 10 has three legs 11, three arms 16, joints 21 which connect the legs 11 and arms 16, a first reinforcing part 25 (see Figure 12), and a second reinforcing part 26 (see Figure 13). Each leg 11 is a rectangular prism shape with a longitudinal orientation and is approximately 30 to 65 centimeters long. Preferably, the length of the leg 11 is approximately 54 centimeters. Each arm 16 is also longitudinal and is approximately 70 to 90 centimeters long. Preferably, the length of the arm 16 is approximately 88.2 centimeters. The upper end of each leg 11 is connected to the arm 16 via the joint 21, and the arm 16 is positioned between each leg 11. The lower end of each leg 11 is connected to the grounding part 15. The ground contact portion 15 consists of two overlapping plate-like pieces, with both pieces fastened at a single point. As the second plate-like piece rotates relative to the first plate-like piece, the ground contact portion 15 expands, increasing the contact area with the mounting surface (see Figure 7, bottommost ground contact portion 15). At each joint portion 21, the arm portion 16 rotates around the joint portion 21, allowing it to bend freely in the lateral (horizontal) direction. Similarly, at each joint portion 21, the leg portion 11 rotates around the joint portion 21, allowing it to bend freely in the vertical (vertical) direction. Each leg portion 11 and each arm portion 16 are connected to each joint portion 21 by bolts. The joints can be freely deformed by loosening the bolts and secured by tightening the bolts.

[0021] The leg portion 11 is composed of a first leg portion 12, a second leg portion 13, and a third leg portion 14, and the arm portion 16 is composed of a first arm portion 17, a second arm portion 18, and a third arm portion 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 portion 11 and the arm portion 16, and a detachable joint portion 24 that allows the leg portion 11 and the arm portion 16 to be attached and detached.

[0022] One end of the first arm 17 is connected to the upper end of the first leg 12 via the first joint 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 24. The detachable joint 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 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 22. One end of the third arm 19 is connected to the upper end of the second leg 13 via the second joint 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 24.

[0023] In the folded state, the other end of the first arm 17 is detached from the detachable joint 24, while the first leg 12 and the first arm 17 remain connected. The first leg 12 is bent at the first joint 22 and lies horizontally on the ground. The second leg 13 is bent at the second joint 23 and lies horizontally on the ground. The third leg 14 is bent at the detachable joint 24 and lies horizontally on the ground. The first arm 17 and the second arm 18 are bent at the first joint 22 and are close to each other. The second arm 18 and the third arm 19 are bent at the second joint 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 portion 14 is close to the third arm portion 19 and the first arm portion 17. Therefore, in the folded state, the first leg portion 12, the second leg portion 13, the third leg portion 14, the first arm portion 17, the second arm portion 18, and the third arm portion 19 are aligned in roughly the same longitudinal direction when lying down, forming a single bundle.

[0024] As shown in Figure 3, the first arm 17 and the second arm 18 are deployed by rotating around the first joint 22, and the second arm 18 and the third arm 19 are deployed by rotating around the second joint 23. As shown in Figures 4 and 5, when the other end of the first arm 17 is connected to the third leg 14 via the detachable joint 24, the first arm 17, the second arm 18, and the third arm 19 are arranged in a triangular shape. The first arm 17 extends laterally between the adjacent first leg 12 and the third leg 14, the second arm 18 extends laterally between the adjacent first leg 12 and the second leg 13, and the third arm 19 extends laterally between the adjacent second leg 13 and the third leg 14.

[0025] In Figures 4 and 5, when the first leg portion 12 rotates around the first joint portion 22 and stands up vertically, the second leg portion 13 rotates around the second joint portion 23 and stands up vertically, and the third leg portion 14 rotates around the detachable joint portion 24 and stands up vertically, the antenna mount 10 is in a supported state, as shown in Figure 6. In the supported state, the second reinforcing portion 26 is further connected across the first arm portion 17 and the first leg portion 12, across the second arm portion 18 and the first leg portion 12, across the second arm portion 18 and the second leg portion 13, across the third arm portion 19 and the second leg portion 13, across the third arm portion 19 and the third leg portion 14, and across the first arm portion 17 and the third leg portion 14. Furthermore, as shown in Figure 7, the first reinforcing section 25 is connected across the first arm section 17 and the second arm section 18, the first reinforcing section 25 is connected across the second arm section 18 and the third arm section 19, and the first reinforcing section 25 is connected across the first arm section 17 and the third arm section 19.

[0026] As shown in Figures 8 and 9, in the supported state of the antenna mount 10, the antenna tripod 5 is attached to the upper end of the leg portion 11.

[0027] By the way, the first reinforcing part 25 and the second reinforcing part 26 are attached to their respective arm parts 16 and are detachable from the arm parts 16. The arm parts 16, the first reinforcing part 25 and the second reinforcing part 26 will now be described based on the drawings. Figures 10 and 11 show the arm parts 16. Figure 12 shows the first reinforcing part 25, and Figure 13 shows the second reinforcing part 26.

[0028] As shown in Figure 10, each arm portion 16 is longitudinal and has an L-shaped cross-section. Multiple mounting holes 20 are formed in the arm portion 16, and bolts, nuts, washers, etc. are attached to the mounting holes 20 as appropriate. 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 the width of the arm portion 16 or narrower than the width of the arm portion 16.

[0029] As shown in Figure 12, the first reinforcing portion 25 is a long, flat plate shape and has multiple first reinforcing portion mounting holes 27 formed therein. As shown in Figure 13, the second reinforcing portion 26 is a flat plate shape and is twisted, with second reinforcing portion mounting holes 28 formed at both ends. That is, the second reinforcing portion 26 is twisted between its ends because it is connected to the side surface of each leg portion 11 and the lower surface of each arm portion 16.

[0030] One first reinforcing section 25 is placed on the upper surface of the arm section 16, and bolts or the like are passed through the mounting holes 20 and the first reinforcing section mounting holes 27. One second reinforcing section 26 is placed on the lower surface of one end of the arm section 16, and another second reinforcing section 26 is placed on the lower surface of the other end, and bolts or the like are passed through the mounting holes 20 and the second reinforcing section mounting holes 28 in each case. Therefore, one first reinforcing section 25 and two second reinforcing sections 26 are attached to the arm section 16.

[0031] As described above, the antenna mount 10 is constructed. Next, the effects of the antenna mount 10 will be explained.

[0032] As described above, the antenna mount 10, when folded, has the third leg 14 and first arm 17 detached at the detachable joint 24, and each leg 11 and each arm 16 lies on the installation surface, aligned roughly in the same longitudinal direction and bundled together (see Figure 1), making it possible to transport by hand. On the other hand, the third leg 14 and the first arm 17 are connected via the detachable joint 24, and the support state is achieved by rotating each leg 11 and each arm 16 (see Figure 6), making assembly easy. Furthermore, in the support state, each leg 11 is oriented vertically, so it stands upright relative to the installation surface, allowing the antenna 1 to be securely supported at a height higher than the snow cover (see Figure 8). In particular, since each leg 11 is approximately 30 to 65 centimeters long, the antenna 1 can be securely supported at a high position even in snowy environments. As described above, the first arm 17 and the third leg 14 are detached at one point (detachable joint 24) and connected with a single bolt, so even those unfamiliar with assembly can complete the work with just one tool such as a wrench.

[0033] The first reinforcing section 25 and the second reinforcing section 26 are attached to their respective arms 16 and are detachable from the arms 16. In the folded state, the first reinforcing section 25 and the second reinforcing section 26 are housed in their respective arms 16, so the components are bundled together and not bulky. In the supported state, the arms 16 are connected to each other by the first reinforcing section 25, making them robust, and the arms 16 and their respective legs 11 are connected to each other by the second reinforcing section 26, making them even more robust. In other words, each arm 16 and each leg 11 restrains each other, so that they do not rotate unintentionally at their respective joints 21. Also, since the length of the arms 16 is approximately 70 to 90 centimeters, they are easy to transport by hand.

[0034] In the supported state, each arm 16 is arranged in a triangular shape, allowing it to stand stably on the mounting surface and support the antenna 1, compared to a square or circular shape. Furthermore, the ground contact section 15, which consists of two overlapping plate-like pieces, unfolds and spreads out, enabling it to stand stably on the mounting surface. The mounting surface can rotate three-dimensionally relative to each leg 11 to maintain any desired posture, and it is also possible to fine-tune the height relative to each leg 11.

[0035] Next, the antenna stand 40, which is attached to and detached from the antenna mount 10, will be described based on the drawings. Figures 14 and 15 show the antenna stand 40 attached to the antenna mount 10. The antenna stand 40 is used, for example, to replace the existing stand (not shown), which is an accessory of the antenna 1, if the existing stand is fragile or if the height of the existing stand is too low.

[0036] As shown in Figures 14 and 15, the antenna stand 40 has a metal attachment / detachment part 41 to which the antenna 1 is attached and detached, a metal opening / closing joint part 47 connected to the lower part of the attachment / detachment part 41, and three metal stand legs 50 extending radially from the opening / closing joint part 47. Each stand leg 50 is a long rectangular prism shape and opens and closes starting from the opening / closing joint part 47. The tip of each stand leg 50 has a connecting part 51 for connecting to the upper end of the leg 11 of the antenna mount 10. Therefore, when the opened stand leg 50 is connected to the leg 11 of the antenna mount 10, the antenna stand 40 is connected to the antenna mount 10. Note that the connecting part 51 may also be present on the leg 11 of the antenna mount 10.

[0037] Here, the opening / closing joint 47 and the attachment / detachment part 41 will be described in detail based on the drawings. Figures 16 and 17 show the opening / closing joint 47, and Figures 18 to 20 show the attachment / detachment part 41.

[0038] As shown in Figures 16 and 17, the opening and closing joint 47 is divided into three branches and has three joint bases 48. Each joint base 48 has a pair of base pieces 49 facing each other, and the stand leg 50 is connected between the base pieces 49. A detachable part 41 is formed on the upper surface of the opening and closing joint 47.

[0039] As shown in Figures 18 to 20, the support column 2 of the antenna 1 is connected to the detachable part 41. The support column 2 has a locking structure. The locking structure is designed to allow the hook-shaped part 3 to move in and out from the side of the support column 2. That is, when no external force is applied to the pressing part 4 which is integrated with the hook-shaped part 3, the hook-shaped part 3 protrudes from the side of the support column 2, but when the pressing part 4 is pressed, the hook-shaped part 3 retracts into the inside of the support column 2.

[0040] The detachable part 41 has a structure to prevent theft of the antenna 1, and includes a cylindrical locking part 42 into which the support column 2 of the antenna 1 is inserted and locked, and a cylindrical cover part 43 that covers the locking part 42. A locking hole 45 and a locking part flange piece 46 are formed on the side of the locking part 42. The hook-shaped part 3 of the support column 2 is locked into the locking hole 45. The locking part flange piece 46 is a flat plate-like piece that extends in the vertical direction and protrudes outward from the side of the locking part 42. On the other hand, a cover part flange piece 44 is formed on the side of the cover part 43. The cover part flange piece 44 is a flat plate-like piece that extends in the vertical direction and protrudes outward from the side of the locking part 42.

[0041] Next, the use of the detachable part 41 will be explained. First, the cover part 43 is passed through the support column part 2 of the antenna 1. Then, the locking part 42 is connected to the support column part 2. Specifically, as the support column part 2 is inserted into the locking part 42, the hook-shaped part 3 is pushed against the inner surface of the locking part 42 and housed inside the support column part 2, and the hook-shaped part 3 is locked into the locking hole 45 from the inside of the locking part 42. Finally, the cover part 43 is lowered along the support column part 2, and the locking part 42 is covered by the cover part 43. The locking part flange piece 46 and the cover part flange piece 44 are overlapped and connected by, for example, a padlock (not shown).

[0042] The antenna stand 40 is configured as described above. Next, the effects of the antenna stand 40 will be explained.

[0043] As described above, the antenna stand 40 is robust because each component is made of metal, and is particularly durable when used outdoors. Furthermore, since the stand legs 50 can be opened and closed, the angle of the stand legs 50 relative to the opening and closing joint 47 can be arbitrarily selected, so the antenna 1 is positioned high above the mounting surface (see Figure 15), resulting in high radio wave reception sensitivity.

[0044] The hook-shaped portion 3 of the support column portion 2 of the antenna 1 is locked to the locking portion 42 of the attachment / detachment portion 41, and the locking portion 42 is covered by the cover portion 43 of the attachment / detachment portion 41, making it impossible to operate the locking portion 42 from the outside. This prevents the support column portion 2 from being unintentionally removed from the attachment / detachment portion 41 (see Figures 18 to 20). Therefore, theft of the antenna 1 is prevented.

[0045] The locking flange piece 46 and the cover flange piece 44 are overlapped, and when they are connected, for example, by a padlock, the cover piece 43 remains immobile, covering the locking piece 42. As a result, the locking piece 42 is not unintentionally exposed, and operation is deterred (see Figures 18 to 20). Therefore, the theft of the antenna 1 is prevented.

[0046] 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. Therefore, when the open stand leg 50 is connected to the leg 11, the antenna stand 40 is connected to the antenna mount 10 (see Figure 14). Because the stand leg 50 is connected to the antenna mount 10, the antenna 1 is positioned at an even higher position as it rises upward from the mounting surface. As a result, the radio wave reception sensitivity is high.

[0047] Next, an antenna stand 140 according to another embodiment will be described based on the drawings. Figure 21 shows the main parts of the antenna stand 140. In the following description, the configurations that differ from those of the antenna stand 40 will be mainly described, and the descriptions of configurations similar to those of the antenna stand 40 will be omitted as appropriate.

[0048] As shown in Figure 21, the antenna stand 140 differs from the antenna stand 40 in that the attachment / detachment part 141 is a long rod shape, and each stand leg 150 has a hook part 152 formed on it.

[0049] Since the attachment / detachment part 141 is a long rod, the position of the antenna 1 is relatively higher by the amount corresponding to its length. For example, if the attachment / detachment part 141 has an extendable structure or a structure in which another rod-shaped member (not shown) is added, the attachment / detachment part 141 can be changed to any length.

[0050] The hook portion 152 is positioned between the upper and lower ends of the stand leg portion 150 and is formed on the underside of the stand leg portion 150 when viewed from above. The hook portion 152 is a plate-like piece with a hole, a hook, or a ring, etc. A chain or string (hereinafter referred to as "chain, etc."; not shown in the figure) is passed through each hook portion 152, and the degree to which the stand leg portion 150 is opened and closed changes according to the length of the chain, etc. For example, if the length of the chain, etc. is short, the stand leg portions 150 are closer together, so the degree of opening and closing is narrow. Therefore, the position of the antenna 1 is relatively higher. On the other hand, if the length of the chain, etc. is long, the stand leg portions 150 are far apart, so the degree of opening and closing is wide. Therefore, the position of the antenna 1 is relatively lower.

[0051] Because the detachable part 141 or the stand leg 150 allows the antenna 1 to be positioned high above the mounting surface, the radio wave reception sensitivity is high. In addition, the antenna 1 may include any type of antenna (not shown), such as antenna 1a or antenna 1b.

[0052] In another embodiment of the present invention, the first reinforcing portion is attached to the leg portion. In another embodiment, the second reinforcing part is attached to the arm. In another embodiment, the first reinforcing part is attached to the lower surface of the arm, and the second reinforcing part is attached to the upper surface of the arm. In another embodiment, there is no first reinforcement and / or second reinforcement. In another embodiment, the leg length is arbitrary. Therefore, the leg length may be less than 30 centimeters or 66 centimeters or more. The leg length is selected according to the expected snowfall. In another embodiment, the number of legs and arms is arbitrary. Therefore, it may have four or more legs and arms. In another embodiment, the length of the arm is arbitrary. Therefore, the arm length may be less than 70 centimeters or 91 centimeters or more. The arm length affects the ease of transport and is influenced by the size of the antenna stand, etc., so it is selected according to the physique, strength, gender of the person transporting it, the size of the antenna and stand, etc. In another embodiment, the antenna stand does not have an anti-theft structure. In another embodiment, the antenna stand does not have a connecting part. Therefore, the antenna stand is not connected to an antenna mount and stands independently on the mounting surface.

[0053] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments described above. Furthermore, various design modifications can be made to the present invention without departing from the matters described in the claims. [Explanation of Symbols]
