Description

  The present invention controls a suction unit composed of a suction cup that is sucked to an installation location, a stand that is integrally connected to the suction portion and mounts a mounting body such as an electronic device, and a suction state of the suction portion to the installation location in a detachable manner. In particular, the present invention relates to a stand device that is applied when the mounting body is installed and used in a vehicle or the like.

  In recent years, navigation devices incorporating an audio / video playback device function and a digital broadcast receiving function have become widespread as in-vehicle electronic devices. These in-vehicle electronic devices are mounted on a stand device that is detachably attached to a dashboard or the like in a vehicle as a mounting body. This stand device can be installed in a place suitable for use of the on-vehicle electronic device, and is extremely advantageous in that it can be used as a portable type with the on-vehicle electronic device removed from the stand device.

  As this type of stand device, for example, a conventional technique shown in the following Patent Document 1 (Japanese Patent Laid-Open No. 2008-232259) has been proposed. This conventional stand device is detachably fixed to an installation location such as a dashboard in a vehicle using a suction cup. The suction cup has a flat disk shape, and a central axis projects from the center of the suction cup. The suction cup is disposed below the circular mounting base, and the central axis protrudes above the mounting base. The central axis is configured to be moved up and down by a displacement mechanism provided at the upper part of the mounting base.

  When installing the stand device at the installation location, the stand device is pushed down to bring the suction surface on the lower surface of the suction cup into close contact with the suction surface at the installation location. At this time, the outer peripheral portion of the mounting base is in contact with the outer periphery of the back surface of the suction cup. As a subsequent operation, the center axis is displaced upward by a displacement mechanism. By this operation, the central portion of the suction cup is pulled away in the direction away from the attracted surface. As a result, a vacuum state is established between the suction surface and the surface to be attracted, and the degree of adhesion of the suction cup to the surface to be attracted is increased to obtain a stable fixed state.

  The displacement mechanism includes an axis provided near the upper end of the central axis, a handle that rotates about the axis, and a cam that is provided integrally with the handle. When the handle is suspended, the displacement mechanism has the central axis positioned downward by the cam so that the suction cup is in a flat state. On the other hand, the displacement mechanism is designed to lock the state by sucking the central portion of the suction cup by displacing the central axis upward by a cam when the handle is turned and leveled.

  The conventional stand device having such a configuration is detachably fixed to an arbitrary place by a suction cup. And a vacuum state is forcibly created between the suction surface of the suction cup and the suction surface of the installation location, and the fixed state can be reliably maintained. On the other hand, when the stand device is detached from the installation location, the suction state can be released relatively easily by returning the handle.

JP 2008-232259 A (paragraphs [0012] to [0014], FIG. 9)

  However, in the conventional stand apparatus, since the installation location can be arbitrarily selected, the situation of the attracted surface is not always the same. Therefore, if the attracted surface is formed of a soft material, the attracted surface is deformed by the attracting force when the stand device is removed. Such deformation of the attracted surface is likely to occur frequently because the stand device is often installed in the same place for a long time, resulting in an attracted surface with significantly unevenness, and the smoothness of the attracted surface is lost. In other words, there is a problem that it is not possible to reliably obtain the adsorption again. Moreover, there is a problem that not only the surface to be mounted is deformed but also the surface subjected to the coating treatment is damaged.

  Accordingly, an object of the present invention is to provide a stand device that is free from the adverse effects of, for example, the installation location of the stand device being deformed by an adsorption force.

In order to solve the above problems, the invention of the stand device according to claim 1 of the present application is as follows.
A stand on which an attachment body is mounted, comprising an adsorption portion that is adsorbed to an installation location, a stand that is integrally connected to the adsorption portion, and an operation unit that removably controls the adsorption state of the adsorption portion to the installation location. A device,
The suction portion includes a suction cup (for example, suction cup 201 in the following embodiment) having a suction surface formed of an elastic material, and a support shaft (for example, a suction cup support in the following embodiment) that is suspended from the center of the upper surface of the suction cup. A shaft 202), a threaded portion (for example, the threaded portion 203 in the following embodiment) for threadably coupling the support shaft to the suction cup, and a direction perpendicular to the central axis of the support shaft. A through hole (for example, through hole 205 in the following embodiment),
The stand is provided at the center top of the stand cover that houses the suction portion and is formed with the lower edge of the outer periphery facing the outermost peripheral surface of the suction cup (for example, the stand cover 301 in the following embodiment). A connecting column (for example, the connecting column 302 in the following embodiment) and a recess (for example, the recess 303 in the following embodiment) that loosely fits the support shaft formed in the connecting column,
The operation portion corresponds to an elastic body (for example, elastic body 401 in the following embodiment) interposed between the top surface of the support shaft and the bottom portion of the recess, and the through hole of the connecting column. A cutout portion (for example, the cutout portion 402 in the following embodiment) formed in the side wall by being cut out to be larger than the through hole, and the both ends of the cutout portion are connected to the through hole through the cutout portion. A support shaft (for example, a support shaft 403 in the following embodiment) provided to protrude from the side surface of the column, and is pivotally supported by the support shaft so that the support shaft is moved in the vertical direction and locked at the upper end. A suction lock mechanism (e.g., suction lock mechanism 404 in the following embodiment) having a cam to be
The relative position of the suction cup and the support shaft is changed by the screwing portion.

  The stand device of the present invention has the following excellent effects.

  That is, in the first aspect of the invention, the support shaft is connected to the center of the upper surface of the suction cup by the threaded portion and is suspended, and the support shaft has a through-hole penetrating in a direction perpendicular to the center axis of the support shaft. Is provided. The stand is loosely fitted with a stand cover formed with the lower edge of the outer periphery facing the outermost peripheral surface of the suction cup, a connecting column provided at the center top of the stand cover, and a support shaft formed in the connecting column. And a concave portion. The operation portion is formed by cutting an elastic body inserted between the top surface of the support shaft and the bottom portion of the concave portion and a side wall corresponding to the through hole of the connecting column larger than the through hole. A notch, a support shaft that is fitted into the through-hole and protrudes from the side surface of the connecting column through the notch, and is pivotally supported by the support shaft. The suction lock mechanism has a cam that is moved in the vertical direction and locked at the upper end.

  According to such a configuration, since the support shaft is connected to the suction cup by the screwing portion and can change the relative position with the suction cup, the distance away from the suction surface of the suction cup is changed and the suction force is changed. Can be increased or decreased. Therefore, when the surface to be attracted is subjected to a failure such as deformation or breakage due to the suction force, it is possible to select a small suction force that does not cause such a failure. Further, when the suction surface is tilted, the suction cup is deteriorated, or the like, when the suction force is larger than usual, the stand device can be reliably installed by increasing the suction force. As a result, a stand device can be obtained in which the suction force by the suction cup can be changed and installed according to the state of the suction face and the suction cup with a simple operation.

  Moreover, in order to bring the suction cup into close contact with the suction surface, the connecting column is pushed down with the stand device placed at the installation location, and the suction cup support shaft is pushed down via the elastic body to press the central portion of the suction cup. Press the center of the suction cup firmly against the suction surface. At the same time, the stand cover is also lowered so that the lower edge of the outer periphery of the stand cover directly presses the outermost peripheral edge of the suction cup. Accordingly, the entire suction cup is strongly adhered to the attracted surface, and air can be reliably removed. Then, the cam is rotated by the suction lock mechanism of the operation unit to move the support shaft upward, the suction cup support shaft is displaced upward independently of the stand cover, and the suction cup central portion is lifted away from the suction surface. The state can be locked. In other words, the suction cup is firmly pressed against the surface to be sucked, including the central portion, and the central portion is pulled apart to form a vacuum state. can get.

  As shown in FIGS. 2 and 3, the suction portion 20 is made of a circular elastic material and has a suction cup 201 whose lower portion is slightly recessed at the center and a lower end fixed to the center of the upper surface of the suction cup 201. A suction cup support shaft 202 arranged vertically, a screwing portion 203 for screwing and connecting the suction cup support shaft 202 to the suction cup 201, and a protruding piece 204 attached to the edge of the suction cup 201. It is composed of A through-hole 205 is formed in the suction cup support shaft 202 in a direction perpendicular to the central axis of the suction cup support shaft 202.

  As shown in FIG. 5, the screwing portion 203 includes a support 206 that supports the suction cup 201, a female screw 207 formed on the support 206, and a female screw 207 formed on the outer periphery of the lower end of the suction cup support shaft 202. It is composed of a mating male screw 208.

  As shown in FIGS. 1 to 5, the stand 30 includes a convex spherical stand cover 301 that houses the suction portion 20, a connection column 302 provided on the upper surface of the center top of the stand cover 301, and a connection column 302. A recess 303 (see FIG. 5) formed so that the upper part of the suction cup support shaft 202 fits loosely and connects the suction part 20 and the stand 30 together, and a mounting part 304 provided on the upper surface of the stand cover 301. A connecting arm 305 (see FIG. 1B) whose base portion is attached to the mounting portion 304 so as to be rotatable up and down, and a portable navigation device 50 provided at the tip of the connecting arm 305 are detachably mounted. A mounted portion 306 (see FIG. 1B) to be mounted, and a fixing lever 307 (see FIG. 1B) for fixing the vertical rotation of the connecting arm 305 provided on one side surface of the mounting portion 304; It is al configuration. The stand cover 301 is circular like the suction cup 201, and the lower edge 308 of the outer periphery thereof is formed to oppose the outermost peripheral surface 209 of the upper surface of the suction cup 201.

  As shown in FIGS. 2 and 5, the operation unit 40 includes an elastic body 401 formed of a coil spring interposed between the top surface of the suction cup support shaft 202 and the bottom portion of the recess 303, and the suction cup support shaft 202. A notch 402 formed by being largely cut out in the vertical direction on the side wall of the connecting column 302 corresponding to the drilled through-hole 205, and a notch 402 at both ends of the notch 402 loosely fitted in the through-hole 205. And a support shaft 403 provided so as to project on the side surface of the connecting column 302, and a suction lock mechanism 404 coupled to the support shaft 403. The operation unit 40 is covered with a detachable operation unit cover 405 as shown in FIG.

  The suction lock mechanism 404 includes a cam 406 that is rotatably supported by a support shaft 403 and a lever 407 that rotates the cam 406. As shown in FIGS. 8 and 10, when the lever 407 shown in FIG. 6 is rotated from the suspended state in the direction indicated by the arrow X, the cam 406 is attached to the stand cover 301 as shown in FIGS. 10 and 11. The support shaft 403 is displaced upward by hitting the upper surface 309. The cam 406 is rotated to a position where the flat peripheral portion 409 abuts on the upper surface 309 in a state where the most protruding top portion 408 contacts the upper surface 309 and is locked at that position.

  As shown in FIGS. 10 and 11, the suction lock mechanism 404 in the locked state is configured such that the support shaft 403 greatly displaces the suction cup support shaft 202 upward and sucks the central portion of the suction cup 201 greatly. . In this state, the cam 406 is in a rotational position where the top portion 408 passes through the upper surface 309 and the flat peripheral portion 40 abuts against the upper surface 309, and achieves the lock function by the elastic force of the elastic body 401. Yes.

  Next, the installation method of the stand apparatus 10 of the above-described embodiment will be described. In the installation, two operation procedures performed by the operation unit 40 are performed.

  In the first operation procedure, the stand device 10 shown in FIGS. 4 and 5 is placed at a place where the stand device 10 is to be installed, and the top surface of the connecting column 302 is pushed in the direction indicated by the arrow Y, so Displace in the direction. As a result, as shown in FIG. 6, the lower edge 308 of the periphery of the stand cover 301 comes into contact with the outermost peripheral surface 209 of the upper surface of the suction cup 201. At the same time, as shown in the figure, the spring forming the elastic body 401 is compressed by pushing down the connecting column 302 and pushes down the suction cup support shaft 202 with its elastic force. For this reason, the central portion of the suction cup 201 protrudes and comes into close contact with the surface to be adsorbed to eliminate the air in that portion, and the lower surface of the peripheral edge of the suction cup 201 is in close contact with the surface to be adsorbed.

  4 and 5, the operation of pushing down the connecting column 302 and the operation of removing the air at the central portion of the suction cup 201 in close contact with the surface to be adsorbed are made easy to understand. Although the lower edge 308 of the peripheral edge of the cover 301 and the outermost peripheral surface 209 of the upper surface of the suction cup 201 are shown wide open, in the actual stand device 10, the lower edge 308 of the peripheral edge of the stand cover 301 and the suction cup are so far apparently. The outermost peripheral surface 209 on the upper surface 201 is not wide open.

  As shown in FIGS. 8 and 9, the next operation procedure is to push the lever 407 in the direction indicated by the arrow X and rotate the cam 406 in a state where the connecting column 302 is pushed down. The top portion 408 is passed through the upper surface 309 of the stand cover 301. As a result, as shown in FIGS. 10 and 11, the support shaft 403 at the center of rotation of the cam 406 is displaced, and the suction cup support shaft 202 is largely displaced upward. Accordingly, the central portion of the suction cup 201 is forcibly displaced in a direction away from the mounting surface. As shown in FIG. 11, the lock mechanism 404 is locked at a position where the lever 407 is rotated to the maximum and the flat peripheral portion 409 is in contact with the upper surface 309.

  At this time, the support shaft 403 protrudes to the side surface of the connecting column 302 through the notched portion 402 which is greatly cut out, and is supported by the cam 406 constituting the suction lock mechanism 404. Is performed independently without being limited to the vertical position of the connecting column 302.

  In a state where such an operation procedure has passed, a vacuum state is established between the central portion of the suction cup 201 and the suction surface of the installation location, and the degree of adhesion of the suction cup 201 to the suction surface is increased. In this state, since the periphery of the suction cup 201 is strongly pressed against the attracted surface by the stand cover 301, the vacuum state is maintained permanently. As a result, the stand device 10 is fixedly installed at a desired installation location, and the portable navigation 50 can be mounted.

  When the stand device 10 is detached from the installation location, the lever 407 is rotated in the direction opposite to the arrow X, and the top portion 408 of the cam 406 passes through the upper surface 309 and is operated to return to the original position. As a result, since the locked state is released, the suction cup support shaft 202 is released from the upward displacement state. And the center part of the suction cup 201 is cancelled | released from the state attracted | sucked. Simultaneously with the unlocking, the connecting column 302 is raised by the elastic force of the elastic body 401. Then, the stand cover 301 is also lifted and the lower edge 308 is separated from the outermost peripheral surface 209 of the suction cup 201. Thereafter, the stand device 10 can be removed from the installation location by holding the protruding piece 204 and peeling the suction cup 201 from the attracted surface.

  Next, the case where the suction force on the suction surface of the suction cup 201 is changed will be described with reference to FIGS. 12 to 19. FIGS. 12 to 15 show the case where the suction force is reduced, and FIGS. The case where the force is increased is shown.

  When reducing the suction force, first, as shown in FIGS. 12 and 13, the suction cup 201 or the stand 30 is rotated in the direction in which the male screw 208 is extracted from the female screw 207. As a result, the relative positions of the suction cup 201 and the suction cup support shaft 202 are separated.

  In this way, the stand device 10 in which the suction cup 201 and the suction cup support shaft 202 are separated from each other is placed at a place to be installed, and the top surface of the connecting column 302 is pushed in the direction indicated by the arrow Y to stand cover 301. Is displaced in the direction of the attracted surface (installation surface). As a result, the lower edge 308 of the periphery of the stand cover 301 abuts on the outermost peripheral surface 209 on the upper surface of the suction cup 201. At the same time, the spring forming the elastic body 401 is compressed by pushing down the connecting column 302 and pushes down the suction cup support shaft 202 with its elastic force. Therefore, the suction cup 201 comes into close contact with the surface to be attracted and excludes the air in that portion, and the lower surface of the peripheral edge of the suction cup 201 is firmly attached to the installation surface.

  After that, as shown in FIGS. 14 and 15, the lever 407 is pushed down to rotate the cam 406 while the connecting column 302 is pushed in. By this operation, the support shaft 403 at the rotation center of the cam 406 is displaced upward, and the suction cup support shaft 202 is displaced upward. Accordingly, the central portion of the suction cup 201 is forcibly displaced in a direction away from the mounted surface to be in a suction state. The suction lock mechanism 404 is locked by rotating the lever 407 to the maximum.

  The distance at which the central portion of the suction cup 201 is forcibly separated from the attracted surface is small because the relative position between the suction cup 201 and the suction cup support shaft 202 is set in advance. For this reason, the suction force is reduced, and the suction force by the suction cup 201 is reduced as compared with a normal case.

  On the other hand, when increasing the suction force, the suction cup 201 or the stand cover 301 is rotated in the direction in which the male screw 208 is screwed into the female screw 207, as shown in FIGS. As a result, the relative positions of the suction cup 201 and the suction cup support shaft 202 approach each other.

  In this way, the stand device 10 in which the relative positions of the suction cup 201 and the suction cup support shaft 202 are close to each other is placed, and the top surface of the connecting column 302 is pushed in the direction indicated by the arrow Y to hold the stand cover 301. Displace in the direction of the attracted surface (installation surface). As a result, the lower edge 308 of the periphery of the stand cover 301 abuts on the outermost peripheral surface 209 on the upper surface of the suction cup 201. At the same time, the spring forming the elastic body 401 is compressed by pushing down the connecting column 302 and pushes down the suction cup support shaft 202 with its elastic force. As a result, the suction cup 201 comes into close contact with the surface to be adsorbed and excludes air at that portion, and the lower surface of the peripheral edge of the suction cup 201 is in close contact with the installation surface.

  Then, as shown in FIGS. 18 and 19, in a state where the connecting column 302 is pushed in, the lever 407 is pushed down to rotate the cam 406. By this operation, the support shaft 403 at the rotation center of the cam 406 is displaced upward, and the suction cup support shaft 202 is displaced upward. Accordingly, the central portion of the suction cup 201 is forcibly displaced in a direction away from the mounted surface to be in a suction state. The suction lock mechanism 404 is locked by rotating the lever 407 to the maximum.

  The distance at which the central portion of the suction cup 201 is forcibly separated from the attracted surface is large because the relative positions of the suction cup 201 and the suction cup support shaft 202 are set close in advance. For this reason, the suction force is increased, and the suction force by the suction cup 201 is increased as compared with a normal case.

  Therefore, according to the stand device 10 of the embodiment of the present invention described above, the suction cup 201 is positively pressed by pushing down the connecting column 302 unlike the prior art, and thus strongly against the suction surface of the installation location. Adhere closely to eliminate air. Therefore, the vacuum state obtained by the next suction operation is ensured, and the suction cup 201 is firmly adsorbed on the attracted surface. Further, even if the central portion of the suction cup 201 is recessed or the entire shape is distorted by using the stand device 10 for many years, the central portion is positively pressed and pushed in greatly, Can absorb the gap formed between the surface to be adsorbed and adhere to the surface to be adsorbed. Therefore, the air can be surely excluded.

  Moreover, since the suction cup support shaft 202 is connected to the suction cup 201 by the screwing portion 203 and can be changed in relative position with the suction cup 201, the suction cup 201 is changed by changing the distance away from the suction surface of the suction cup 201. You can increase or decrease the power. In the operation, when the suction force is decreased, the suction screw 201 or the stand 30 may be rotated in the direction in which the male screw 208 is extracted from the female screw 207. On the other hand, when the suction force is increased, the suction cup 201 or the stand 30 may be rotated in the direction in which the male screw 208 is screwed into the female screw 207.

  By such a simple operation, when the attracted surface is made of a soft material, the suction cup 201 can be attracted to the attracted surface with a smaller attracting force than usual. Therefore, no deformation occurs on the attracted surface. As a result, it is possible to maintain a good adsorption state by always keeping the adsorbed surface smooth. In addition, since it is possible to prevent the surface to be adsorbed that has been subjected to the coating treatment from being damaged, it is possible to always maintain an aesthetic appearance.

  Further, the stand device 10 may be installed on an inclined surface to be attracted. In this case, the suction force can be increased more than usual by the screwing operation of the screwing portion 203. As a result, the suction cup 201 does not come off the inclined suction surface due to the weight of the stand device 10 and the portable navigation device 50. Further, even when the suction cup 201 is deteriorated, the suction force can be increased, so that a good suction state can always be obtained.

  In order to discharge the air between the suction cup 201 and the suction surface more reliably, the male screw 208 is rotated in the direction of extracting from the female screw 207 so that the relative distance between the suction cup support shaft 202 and the suction cup 201 is increased. The top of the connecting column 302 is pushed down and the stand cover 301 is displaced toward the attracted surface. As a result, the central portion of the suction cup 201 is strongly pressed against the attracted surface, and the air in that portion is surely excluded.

  In this state, if the stand device 10 is rotated and the male screw 208 is screwed into the female screw 207, the relative distance between the suction cup support shaft 202 and the suction cup 201 is reduced, and the fixing lever 407 is rotated and locked. The central portion of the suction cup 201 is greatly displaced upward to increase the suction force. Therefore, the air between the suction cup 201 and the surface to be adsorbed is more reliably eliminated, and the suction surface is adsorbed to the surface to be adsorbed by a large suction force.

  Further, the suction lock mechanism 404 does not unnecessarily rotate the lever 407 from the initial position because the cam 406 is always in contact with the upper surface 309 of the stand cover 301. Therefore, the suction operation of the suction cup 201 by the turning operation of the lever 407 is performed reliably.
