Problems to be Solved by the Invention
[0004] However, the conventional technology as described above adsorbs to the adsorption surface by the negative pressure generated between the elastic body and the adsorption surface, and operates an on-off valve that controls the outflow of air using a gripping portion at the upper part of the stand. For this reason, there is a problem that the configuration is complicated, the number of parts increases, and the manufacturing cost is high.
[0005] One aspect of the present invention aims to provide an electronic device that can suppress toppling with a simple configuration.
Means for Solving the Problems
[0006] To solve the above problems, an electronic device according to one aspect of the present invention comprises an electronic device body, a base portion having an adsorption portion that adheres to a mounting surface, and a stand having a support portion erected vertically from the base portion and to which the electronic device body is attached, wherein the adsorption portion is provided with a roll-up portion that is compressed vertically when the stand to which the electronic device body is attached is placed on the aforementioned mounting surface, and is switchable between a first state and a second state, wherein when the roll-up portion is in the first state, the air in the gap between the adsorption portion and the aforementioned mounting surface is discharged due to the weight of the electronic device body, causing the roll-up portion to adhere to the aforementioned mounting surface due to the negative pressure generated in the gap, and when the roll-up portion is in the second state, air is supplied to the gap from between the roll-up portion and the aforementioned mounting surface, thereby releasing the adsorption, and the device further comprises an operation portion for switching the roll-up portion between the first state and the second state. [Effects of the Invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. The electronic device 1 according to the present invention may be any electronic device supported by a stand, and can be applied to various display devices such as television receivers, computer liquid crystal displays, and information displays. An example in which the electronic device 1 is a television receiver will be described below.
[0010] <Overview of Electronic Device 1> Figure 1 is a perspective view showing an example of the external appearance of an electronic device 1 according to an embodiment of the present invention. Here, in the normal operating state of the electronic device 1, the direction pointing upwards is referred to as the Y1 direction, and the direction opposite to the Y1 direction (downwards) is referred to as the Y2 direction. When Y1 and Y2 are not distinguished from each other and are referred to collectively as the Y direction.
[0011] The electronic device 1 according to the present invention is a large television receiver, for example, 55 inches to 75 inches in size, but is not limited to this, and may be smaller than 55 inches or larger than 75 inches.
[0012] As shown in Figure 1, the electronic device 1 comprises an electronic device body 2 and a stand 3. The electronic device body 2 is, for example, a display device for a television receiver that displays images and various information, and is implemented using a liquid crystal display, an organic EL display, a plasma display, etc.
[0013] The stand 3 includes a support portion 4 and a base portion 5, and supports the main body 2 of the electronic device. The support portion 4 stands upright in a substantially vertical direction from the base portion 5, and the main body 2 of the electronic device is attached to the side opposite to the base portion 5 side.
[0014] The base portion 5 is configured in a substantially flat plate shape and is placed on a mounting table of the electronic device 1 or on the floor or the like. In a normal use state, a load due to the weight (self-weight) of the main body 2 of the electronic device is applied to the base portion 5. As will be described in detail later, the base portion 5 includes an elastic member 51 (elastic body) attached to the lower surface of the base portion 5 so as to contact the mounting surface 6. By the adsorption portion 511 of the elastic member 51 being adsorbed to the mounting surface 6 by negative pressure, the electronic device 1 can be prevented from falling over.
[0015] <Overview of the stand 3> Next, the overview of the stand 3 will be described with reference to the drawings. FIG. 2 is a perspective view showing an example of the stand 3. The figure indicated by reference numeral 200A is a view of the stand 3 as seen from the front side and the left side, and the figure indicated by reference numeral 200B is a view of the stand 3 as seen from the front side and the right side. In FIG. 2, the housing 40 of the support portion 4 is shown by a two-dot chain line so that the inside of the support portion 4 can be shown. FIG. 3 is a front view of the stand 3, FIG. 4 is a rear view of the stand 3, FIG. 5 is a left side view of the stand 3, FIG. 6 is a right side view of the stand 3, FIG. 7 is a plan view of the stand 3, and FIG. 8 is a bottom view of the stand 3. In FIGS. 3 to 8, the housing 40 and the screw 423 for attaching the guide portion 42 to the housing 40 are not shown. FIG. 9 is an exploded perspective view of the bottom side showing a part of the stand 3 disassembled.
[0016] As shown in FIGS. 2 to 7, the support portion 4 includes an accommodation space 44 (see FIG. 2) inside the housing 40 (see FIG. 2) of the stand 3. The operation portion 41 and the guide portion 42 are arranged in the accommodation space 44.
[0017] The operating unit 41 is connected to the winding portion 513 of the elastic member 51, which will be described later. By switching the state of the winding portion 513 using the operating unit 41, the suction portion 511 can be switched between an suction state and a non-suction state. Details of the operating unit 41 will be described later.
[0018] The guide section 42 is roughly plate-shaped and includes a front side 42a (see Figure 5), a back side 42b opposite to the front side 42a (see Figure 6), and a guide hole 421 that penetrates the guide section 42. An operating section 41 is attached to the guide section 42 so as to be slidable along the guide hole 421. The upper part of the guide section 42 is fixed to the housing 40 by, for example, a number of screws 423 (see Figure 2), and the lower part is fixed to the base section 5 by screws or the like (not shown). Details of the guide section 42 will be described later.
[0019] As shown in Figures 8 and 9, the base portion 5 has a recess 50 on its lower surface that is recessed in a direction away from the mounting surface 6. An elastic member 51 is fitted into the recess 50, and a retaining plate 54 is positioned below the elastic member 51. The elastic member 51 is fixed to the recess 50 together with the retaining plate 54 by screws 541.
[0020] Furthermore, the base portion 5 has an opening 53 (see Figure 9) that penetrates the base portion 5 in the Y direction. The mounting portion 512 of the elastic member 51, which will be described later, is inserted through the opening 53 from the bottom to the top of the base portion 5 in the Y1 direction. Air is also supplied into or discharged from the gap portion 52 through the opening 53. Details of the supply and discharge of air into the gap portion 52 through the opening 53 will be described later.
[0021] <Elastic member 51> Next, the elastic member 51 will be described with reference to the drawings. Figure 10 shows an example of the elastic member 51. The figure indicated by reference numeral 100A is a perspective view of the elastic member 51, the figure indicated by reference numeral 100B is a side view, and the figure indicated by reference numeral 100C is a cross-sectional view taken along section line AA (see reference numeral 1000A).
[0022] As shown in Figure 10, the elastic member 51 is configured in the shape of an inverted dish with a central recess. The elastic member 51 is made of silicone and is formed to a thickness of, for example, about 1.0 mm to 5.0 mm, preferably about 3.0 mm. The elastic member 51 includes a flat portion 510, an adsorption portion 511, an attachment portion 512, a curling portion 513, and an internal space 514.
[0023] The flat portion 510 is a substantially flat portion formed on the upper surface of the elastic member 51. The elastic member 51 is fixed to the recess 50 of the base portion 5 such that the flat portion 510 and the recess 50 of the base portion 5 are in contact with each other.
[0024] The suction portion 511 is the peripheral portion of the elastic member 51 and is flexible. The suction portion 511 adheres to the mounting surface 6 when the gap 52 (see Figure 14) between the suction portion 511 and the mounting surface 6, which will be described later, is under negative pressure.
[0025] The elastic member 51 is attached to the recess 50, for example, so as to protrude downward (in the Y2 direction) from the bottom surface of the legs of the base portion 5. Therefore, when the electronic device 1 is placed on the mounting surface 6, the suction portion 511 is compressed vertically (in the Y2 direction) due to the weight of the electronic device body 2, etc.
[0026] As a result, the air in the gap 52 is expelled, and the compressed suction part 511 attempts to return to its original shape due to its elasticity, generating negative pressure in the gap 52. Due to the generation of negative pressure in the gap 52, the area near the end 511a of the suction part 511 adheres to the mounting surface 6. In this way, the suction part 511 adheres to the mounting surface 6, preventing the electronic device 1 from tipping over.
[0027] The roll-up portion 513 is part of the suction portion 511, and is the portion of the suction portion 511 located near the mounting portion 512. As described above, the roll-up portion 513 can be switched between a state in contact with the mounting surface 6 (first state) and a state separated from the mounting surface 6 (second state) by operating the operating portion 41.
[0028] The mounting portion 512 is the part that connects the winding portion 513 and the operating portion 41, and is attached to the operating portion 41. The mounting portion 512 has a shape that protrudes upward (in the Y1 direction) from the winding portion 513, for example. The mounting portion 512 comprises a base portion 512a and a main body portion 512b.
[0029] The base portion 512a is formed by extending from the winding portion 513. As described above, the main body portion 512b is inserted through the opening 53 and then inserted into the housing portion 411 of the operating portion 41, which will be described later, and fixed in place. This allows the operating portion 41 to operate the winding portion 513 connected to the main body portion 512b and switch the state of the winding portion 513.
[0030] The mounting portion 512 is not limited to this and may be composed of a separate component from the elastic member 51. The mounting portion 512 only needs to be structured to connect to or fit with the winding portion 513 and allow the winding portion 513 to be wound up. For example, it may be a string-like member connecting the back surface of the winding portion 513 to the operating portion 41, or it may be any other structure.
[0031] <Operation section 41 and guide section 42> Figure 11 is a perspective view showing an example of the operating section 41. The figure indicated by reference numeral 1100A is a perspective view seen from the side where the operating knob 415 is located, and the figure indicated by reference numeral 1100B is a perspective view seen from the opposite side of reference numeral 1100A. Figure 12 is a perspective view showing an example of the operating section 41 attached to the guide section 42. The figure indicated by reference numeral 1200A is a perspective view seen from the front side 42a of the guide section 42, and the figure indicated by reference numeral 1200B is a perspective view seen from the back side 42b of the guide section 42. Figure 13 is an exploded perspective view showing the operating section 41, the guide section 42, and the elastic member 51 in disassembled form.
[0032] As shown in Figures 11 to 13, the operating section 41 comprises a housing section 411, a pair of rail sections 412, a mounting piece 413, a projection 414, and an operating knob section 415 (operating piece). The guide section 42 comprises a pair of guide holes 421 and a hole section 422.
[0033] The housing section 411 is formed within the operating section 41, and as described above, the mounting section 512, which passes through the opening 53, is inserted into the housing section 411. The inserted mounting section 512 is fixed to the operating section 41, for example, by screws or the like.
[0034] The rail section 412 is a pair of rail-shaped members. The rail section 412 is inserted into the guide hole 421 of the guide section 42 so as to be slidable along the guide hole 421. The number of rail sections 412 is not limited to this; there may be one or three or more.
[0035] The mounting piece 413 is a member that connects a pair of rail sections 412, which are inserted into the guide hole 421 from the front side 42a, from the back side 42b. This prevents the rail sections 412 from unintentionally coming out of the guide hole 421.
[0036] The projection 414 is, for example, a roughly hemispherical projection that fits into the hole 422a or hole 422b of the guide portion 42.
[0037] The operating knob 415 is a component operated by the operator when operating the operating unit 41. By pinching the operating knob 415 with their fingers and moving it up and down, the operator can move the operating unit 41 along the guide hole 421.
[0038] At this time, the mounting portion 512 inserted into the operating portion 41 also moves along the guide hole 421 as the operating portion 41 moves. As will be described in more detail later, this makes it possible to switch the state of the winding portion 513 connected to the mounting portion 512 between a state in contact with the mounting surface 6 and a state separated from the mounting surface 6.
[0039] The housing 40 of the support unit 4 is provided with a window 43 (see Figure 200B) that exposes the operating knob 415 of the operating unit 41. This allows the operator to operate the operating knob 415 by inserting their finger through the window 43 without removing the housing 40. Furthermore, by visually checking the position of the operating knob 415, it is possible to confirm whether or not the suction unit 511 is in a suction state.
[0040] The guide hole 421 in the guide section 42 is a through hole that penetrates the guide section 42, and as described above, it is the hole into which the rail section 412 of the operating section 41 is inserted. The guide hole 421 is longer in the axial direction than the rail section 412. As a result, the rail section 412 can slide and move along the guide hole 421.
[0041] By moving the rail section 412 downward (in the Y2 direction) along the guide hole 421, the operating section 41 can be moved in a direction closer to the mounting surface 6. Conversely, by moving the rail section 412 upward (in the Y1 direction) along the guide hole 421, the operating section 41 can be moved in a direction further away from the mounting surface 6.
[0042] The guide hole 421 extends in the vertical direction (Y direction), but is not limited to this; it may extend in a direction that is close to the mounting surface 6 or in a direction that is away from the mounting surface 6. For example, it may extend diagonally upward from a position near the mounting surface 6.
[0043] The hole 422 includes a hole 422a located on the upper side (Y1 direction side) and a hole 422b located on the lower side (Y2 direction side) of the hole 422a.
[0044] The hole 422a is a hole into which the projection 414 of the operating part 41 fits when the operating part 41 moves upward (towards the Y1 direction) along the guide part 42. As will be described in more detail later, at this time the winding part 513 is separated from the mounting surface 6, and the suction between the suction part 511 and the mounting surface 6 is released.
[0045] The hole 422b is a hole into which the projection 414 of the operating part 41 fits when the operating part 41 moves downward (towards the Y2 direction) along the guide part 42. As will be described in more detail later, at this time the winding part 513 comes into contact with the mounting surface 6, and the suction part 511 becomes capable of adhering to the mounting surface 6.
[0046] In this way, by operating the operating unit 41, the state of the winding unit 513 can be switched between a state in contact with the mounting surface 6 and a state separated from the mounting surface 6, thereby allowing the suction unit 511 to be attached to the mounting surface 6 or released from the attached state.
[0047] <Adsorbed state and non-adsorbed state> Figure 14 illustrates the adsorption state of the adsorption part 511. The figure indicated by reference numeral 1400A is a schematic diagram showing the state in which the adsorption part 511 is adsorbed to the mounting surface 6. The figure indicated by reference numeral 1400B is a schematic diagram illustrating the release of the adsorption state of the adsorption part 511.
[0048] First, let's describe the state in which the suction part 511 is adsorbed to the mounting surface 6. As indicated by reference numeral 1400A, when the operating part 41 moves along the guide part 42 and is positioned on the lower side (Y2 direction side) (hereinafter referred to as "position P1"), the mounting part 512 inserted into the housing part 411 is also in position P1.
[0049] As described above, the elastic member 51 is attached to the recess 50 so as to protrude downward (in the Y2 direction) from the base portion 5. Therefore, when the electronic device 1 is placed on the mounting surface 6, the weight of the electronic device body 2 compresses the suction portion 511 vertically (in the Y2 direction), and the air in the gap 52 between the suction portion 511 and the mounting surface 6 is discharged from the opening 53.
[0050] At this time, since the mounting portion 512 is at position P1, the rolled-up portion 513 near the mounting portion 512 comes into contact with the mounting surface 6, and the gap portion 52 is kept airtight. As the compressed suction portion 511 tries to return to its original shape due to its elasticity, negative pressure is generated in the gap portion 52. As a result, the end portion 511a of the suction portion 511 adheres to the mounting surface 6.
[0051] Next, we will explain how to release the suction state of the suction part 511. As indicated by reference numeral 1400B, when the operating part 41 moves upward (towards the Y1 direction) along the guide part 42 (hereinafter referred to as the "P2 position"), the mounting part 512 inserted into the housing part 411 also moves to the P2 position.
[0052] At this time, as the mounting portion 512 moves, the roll-up portion 513 connected to the mounting portion 512 is pulled by the mounting portion 512 and rolls up upward (in the Y1 direction). As a result, the roll-up portion 513 separates from the mounting surface 6, and air is supplied into the gap portion 52 from between the roll-up portion 513 and the mounting surface 6 through the opening 53. This eliminates the negative pressure in the gap portion 52, and the suction between the suction portion 511 and the mounting surface 6 is released.
[0053] This allows the electronic device 1 to be moved and placed in any desired location. When the electronic device 1 is placed in any desired location, a negative pressure is generated by the weight of the electronic device body 2, and the suction part 511 is re-adhered to the mounting surface 6.
