Summary of the Invention

Problems to be Solved by the Invention

[0006] However, a conventional electronic device that can be used both on a desktop and on a wall can be installed only by moving the electronic device housing vertically with respect to the wall mounting pin WP attached to the wall, and it is necessary to perform the work after bringing the housing close to the wall surface without a gap during the installation work. Therefore, there is a problem that the wall mounting work is difficult because it is a wall mounting work in a state where visual confirmation is not possible.

[0007] This invention has been made in view of the above-mentioned conventional problems, and one of its objectives is to provide an electronic device that can be used both as a wall-mounted or desktop-standing electronic device, by utilizing a stand to hold the main unit used when it is desktop-standing, thereby improving the ease of installation when wall-mounted. [Means for solving the problem]

[0008] The electronic device according to the present invention comprises a housing body portion containing electronic device elements, and a plate-shaped stand whose one end is rotatably coupled to the housing body portion around a pivot axis along the surface of the housing body portion, wherein the housing body portion has a hook portion that engages with one surface of the stand to hold the stand, and the stand has a first recess formed on the free end opposite to the one end of the other surface opposite to the first surface, which engages with a first protrusion provided on the wall when the housing body portion is hung on the wall for installation, and the first recess has a retaining portion that can hold the first protrusion, which is inserted when the stand is in a position rising from the housing body portion, while the first surface of the stand rotates to approach the housing body portion. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide an electronic device that improves ease of installation when wall-mounted by utilizing a stand that holds the main unit when it is placed on a tabletop. [Brief explanation of the drawing]

[Figure 6C] This is a schematic cross-sectional view of the electronic device of this embodiment. [Modes for carrying out the invention]

[0011] An example of an electronic device according to the present invention, such as a telephone, will be described in detail with reference to the drawings.

[0012] In the following explanation, when the electronic device is wall-mounted or tilted on a table, the upward direction of the electronic device will be referred to as the X direction, and the downward direction as the Y direction.

[0013] Figure 1 is a perspective view from the rear of the electronic device ED in this embodiment, particularly showing the main unit support structure. Figure 1 shows the wall-mounted mode of the main unit rear 1 (main housing) of the electronic device ED, with the stand 3 folded around the stand rotation axis 2 (rotation axis). Although not shown, the front side of the electronic device ED is equipped with, for example, a liquid crystal display device at the top that displays the dial number and status of the other party, a number of function buttons in the center, a dial button at the bottom, and a handset mounted on the right side of the front surface.

[0014] For example, the casing of an electronic device is a roughly rectangular prism with rounded corners. The casing may be made of plastic and consist of a structure that combines, for example, a front case half and a back case half, each molded as a single piece. The shape of the casing is not limited to a roughly rectangular prism and can be any shape.

[0015] Figure 2 is an exploded perspective view showing the main support structure of the electronic device ED as seen from the rear side.

[0016] FIG. 3 shows a desktop mode in which the stand 3 is rotated around the stand rotary shaft 2 and opened from the back surface 1 of the main body, and the electronic device ED can stand independently by the lower side of the back surface 1 of the main body and the tip of the stand 3.

[0017] [Back surface of main body] As shown in FIG. 1, at substantially the center of the back surface 1 of the main body, three bearing portions 4 arranged horizontally and capable of attaching the stand rotary shaft 2 of the stand 3 are provided.

[0018] The stand 3 is rotatably attached around the stand rotary shaft 2 (one end portion) by the bearing portion 4 on the back surface 1 of the main body.

[0019] On the back surface 1 of the main body, a group of lower hook portions 6 (gripping portions) are arranged below the bearing portion 4. A pair of horizontal hook portion sets are arranged in parallel in two stages in the XY direction (up and down). The two sets of lower hook portions 6 are used for adjusting the angle of the electronic device ED when standing independently on the desktop. Each of the lower hook portions 6 detachably grips the engaging portion 5a at the tip of the link 5.

[0020] Also, on the back surface 1 of the main body, below the bearing portion 4 and above the lower hook portion 6, a lower mounting convex portion 8 protruding in a box shape at a height H1 (see FIG. 6C) from the back surface 1 of the main body is formed. In the lower mounting convex portion 8, a lower mounting hole 8h (second recess) is formed at the center of the back surface 1 of the main body. The lower mounting hole 8h is used for holding the electronic device ED when wall-mounted.

[0021] Also, on the back surface 上に of the main body, above the bearing portion 4, a pair of horizontal upper hook portions 1f are arranged. The upper hook portions 1f are used for holding the folded stand 3 to the back surface 1 of the main body when wall-mounted.

[0022] Slip prevention members 1j that contact the table when standing independently on the desktop are attached to both lower end side surfaces at the lower end of the back surface 1 of the main body.

[0023] [Stand] The stand 3 has a pair of parallel side walls 3a extending from the stand rotation axis 2, a cylindrical surface at the free end 3c (free end) of the side wall 3a, and a stand base 3d (surface 1) connecting them. The stand base 3d has a pair of hook receiving holes 3fh formed at positions for engaging the hook portion 1f on the upper part of the main body when the stand is folded, such as when hanging it on a wall.

[0024] The side wall 3a is a roughly rectangular longitudinal member that holds the main body back 1. The height of the side wall 3a is approximately the same as the height H1 (see Figure 6C) of the mounting projection 8 at the bottom of the main body back 1 when the stand 3 is folded.

[0025] A pair of link bearing sections RB, which hold the link 5 on its rotation axis, are provided on the base 3d of the stand, parallel to the stand's rotation axis 2.

[0026] Furthermore, the stand 3 is provided with a recessed groove (mortar) that is deep enough to accommodate the link 5. In other words, the folded link 5 can be stored in the recess, which is partitioned by the link bearing portion RB, a pair of side walls 3a, and the free end 3c of the stand.

[0027] Furthermore, the stand 3's base 3d is provided with an elastic locking piece 3p that secures the link 5 when it is stored.

[0028] Furthermore, an opening 3e is provided around the stand rotation axis 2 of the stand base 3d so as not to come into contact with the bearing portion 4 provided on the back surface 1 of the main body. In addition, a convex base portion 3f is provided around the free end 3c of the stand base 3d, with an upper mounting portion 7 provided in the center.

[0029] The upper mounting portion 7 has a retaining portion 7a. The retaining portion 7a is provided on the inner wall of the upper mounting hole 7h (first recess) for engaging the head of the wall-mounting pin WP (not shown) (see Figure 6A). In other words, the stand 3 has a mounting hole 7h at its upper end. The height of the lower mounting projection 8 is greater than or equal to the height of the lower hook portion 6.

[0030] [link] Link 5, which is a connecting member between the main body back panel 1 and the stand 3, is rotatably attached to a pair of link bearing sections RB located from the center of the stand 3 towards the main body back panel 1. Link 5 is located on the underside of the stand 3.

[0031] As shown in Figure 2, the link 5 has a pair of parallel longitudinal members, each consisting of legs 5b with an engaging portion 5a (angle adjustment engaging portion) at its free end, a link rotation axis 5c (rotating end) spanning the other ends of the legs 5b, and a connecting portion 5d integrated with the link rotation axis 5c, and the whole is formed in the shape of the Japanese katakana character "コ". The legs 5b are roughly rectangular prisms that are slightly bent on the side of the engaging portion 5a. The thickness of the link 5 is less than the depth of the recess in the bottom 3d of the stand so that it can be housed in the stand 3.

[0032] Each of the leg portions 5b is forked at its tip, with an engaging portion 5a spanning and fixed between them. The engaging portion 5a has a cylindrical surface that can be fitted into the lower hook portion 6 on the back of the main body 1. An opening 5e is provided around the engaging portion 5a. This opening 5e is provided for the tip of the lower hook portion 6 to engage when the engaging portion 5a is fitted into the lower hook portion 6 on the back of the main body.

[0033] Near both ends of the link rotation axis 5c of the leg portion 5b of link 5, a pair of openings 5op are provided so that link 5 can rotate on a pair of link bearing portions RB of stand 3.

[0034] The angle between the stand 3 and the back of the main unit 1 is adjusted by fitting the pair of engaging portions 5a of link 5 into the pair of horizontal lower hook portions 6. The electronic device ED is supported upright by its lower end, link 5, and stand 3.

[0035] Furthermore, a locking opening 5ef is provided in the connecting portion 5d of link 5. The locking opening 5ef engages with the elastic locking piece 3p on the bottom portion 3d of stand 3 when link 5 is stored in stand 3, thereby securing the stored link 5.

[0036] Furthermore, to hold the rotating shaft, a C-shaped bearing recess is formed in the bearing section 4 and the link bearing section RB, thereby preventing the stand rotating shaft 2 and the link rotating shaft 5c from falling out through fitting.

[0037] [Tabletop setup instructions] As shown in Figure 4, the user removes link 5 from the stand 3's storage space as indicated by the triangular arrow and rotates it around the link bearing RB. Note that the removal of link 5 may also be done after the stand 3 is opened.

[0038] As shown in Figure 5, the user pulls the mounting part 7 at the top of the free end of the stand 3 downwards from the hook part 1f at the top of the back of the main unit 1, as indicated by the triangular arrow, to raise the stand 3, and rotates the stand 3 around the bearing part 4 to open the stand 3. Then, the engaging part 5a of the link 5 is fitted into one of the lower hook parts 6.

[0039] As described above, according to this embodiment, the stand 3 is held by the bearing portion 4 on the back of the main body 1 and the axis of rotation, the link 5 is held by the stand 3 and the axis of rotation, and a lower hook portion 6 for angle adjustment is provided on the back of the main body 1, thereby achieving the effect that angle adjustment is possible using only two points: the stand 3 and the link 5.

[0040] When adjusting the angle, the only operation required is to insert the cylindrical engaging part 5a at the tip of the link 5 into one of the two lower hook parts 6 on the back of the main unit 1. This makes the structure easy to understand and easy to operate.

[0041] Furthermore, according to this embodiment, a lower hook portion 6 is provided on the back of the main body 1, and the tip of the link 5 is made into a cylindrical engaging portion 5a, thereby achieving a structure that allows for easy attachment and detachment while maintaining a fitting strength that prevents the main body from coming loose even when it is lifted, to the lower hook portion 6 on the back of the main body 1.

[0042] By making the link bearing section RB and bearing section 4 for holding the rotating shaft into bearing recesses with a C-shaped cross-section, the stand rotating shaft 2 and the link rotating shaft 5c are prevented from falling out.

[0043] By providing a recess in stand 3 that allows link 5 to be stored, a structure is achieved that eliminates the need to remove link 5 from stand 3 when mounting it on a wall.

[0044] [Instructions for wall mounting] Figures 6A to 6C are schematic longitudinal cross-sectional views of the electronic device ED, cut along a plane passing through the upper mounting hole 7h and the lower mounting hole 8h, illustrating the procedure for wall-mounting the electronic device ED. In these schematic longitudinal cross-sectional views, the electronic device ED contains various electronic components such as printed circuit boards and wiring, as well as housing elements such as bosses, screws, and ribs. However, for the sake of simplicity, these components are omitted from the diagram.

[0045] When mounting the unit to a wall, as shown in Figure 6A, the user pulls the mounting part 7 at the upper end of the stand 3 downwards from the hook part 1f at the top of the back of the main unit 1, as indicated by the triangular arrow, to raise the stand 3, and then hooks the upper wall mounting pin WP (first protrusion) into the upper mounting hole 7h. At this time, since the stand rotation axis 2 is rotatable, the housing can rotate in the direction of the arrow.

[0046] With the wall-mounting pin WP still attached to the upper mounting hole 7h, the user rotates the electronic device ED around the stand rotation axis 2 in the direction of the triangular arrow, as shown in Figure 6B, to bring it closer to the wall. The upper mounting part 7 is provided with a retaining part 7a on the inner wall of the upper mounting hole 7h for engaging the head of the wall-mounting pin WP, so the head of the wall-mounting pin WP slides on the retaining part 7a while the electronic device ED is rotating.

[0047] As shown in Figure 6C, the user then engages the lower mounting hole 8h on the back of the main body 1 of the electronic device ED with the lower wall-mounting pin WP (second protrusion), and engages the upper hook portion 1f with the hook receiving hole 3fh (see Figure 1). At this time, the height H1 of the upper mounting portion 7 from the back of the main body 1 is equal to the height H1 of the lower mounting protrusion 8, and the back of the main body 1 and the stand 3 are engaged by the upper hook portion 1f and hook receiving hole 3fh, so the rigidity necessary for wall mounting can be ensured even when the stand rotation axis 2 is not fixed. Furthermore, the retaining portion 7a can hold the wall-mounting pin WP, which was inserted when the stand 3 is in a position rising from the back of the main body 1, while the stand 3 rotates to approach the back of the main body 1, preventing the wall-mounting pin WP from coming out.

[0048] (Explanation of effects) As described above, according to this embodiment, the retaining portion 7a prevents the wall mounting pin WP from coming loose during wall mounting, and by arranging one upper mounting hole 7h and one lower mounting hole 8h on the back of the main unit 1 and one on the stand 3, which engage with the wall mounting pin WP, it becomes possible to mount the housing on the wall while rotating it around the stand rotation axis 2, and an improvement in ease of installation can be expected.

[0049] According to this embodiment, by providing mounting holes that engage with wall-mounting pins WP on both the back side of the electronic device ED and the stand 3 which has a rotating mechanism, it becomes possible to install the device while rotating it during wall mounting, thus securing more installation space than in conventional wall mounting methods.

[0050] This embodiment describes an example of its application to the tilt structure of a desktop and wall-mounted telephone, but it can also be applied to the tilt stand structure of desktop electronic devices other than telephones. [Explanation of symbols]
