Yes.

<Overall configuration>
In FIG. 1, a telephone device 1 includes a device main body 10 with a built-in telephone function, a pedestal 20 that supports the device main body 10, and a ratchet unit 30 that supports the inclination angle of the device main body 10 with respect to the pedestal 20 so that the inclination angle can be changed. I have. In addition, the coordinate axes are displayed in FIG. In accordance with the case where the operator operates the telephone device 1, the X axis represents the left and right, and the Y axis represents the depth (front side of the operator). The Z axis represents the vertical direction, and the upper side of the drawing is the upper direction. The plane formed by the X axis and the Y axis is a plane on which the pedestal 20 is placed, and is a horizontal plane such as a tabletop. On the other hand, the plane formed by the X-axis and the Z-axis is a vertical plane, and will be described as a wall surface or “wall hanging”.

  A dotted line shown between the X axis and the Z axis is an inclination angle with the Y axis as a base point. This corresponds to the inclination angle of the apparatus main body 10. Specifically, inclining the apparatus main body 10 upward means increasing the inclination angle. On the contrary, lowering the apparatus main body 10 is to reduce the inclination angle. Making the apparatus main body 10 horizontal means that the apparatus main body 10 is parallel to the pedestal 20 and means that the angle (inclination angle) formed with the Y axis is substantially zero.

  The apparatus main body 10 is formed in a substantially rectangular parallelepiped, and is provided with an operation panel portion 11 on the front surface facing the operator, and a main body base portion 12 that houses a circuit board having a telephone function on the other box-like surface. A handset H is disposed on the left side of the operation panel unit 11. The operation panel unit 11 is provided with a display unit 111 for performing various displays such as a telephone number display, a clock display, and a call time display, and an operation key unit 112 in which numeric keys and function keys are arranged. As the display unit 111, a liquid crystal display panel can be used.

<Body bottom>
In FIG. 2, the bottom surface of the main body base 12 is formed in a shape that gently bulges downward. At the center of the bottom surface, a bottom space 121 is formed in which a vertical section is formed in a substantially triangular shape and bulged in the direction of the pedestal 20. The bottom space 121 forms a bottom side wall 1221 and a main body arcuate peripheral surface 1223. The bottom side wall 1221 is provided with a rotation hole 1222 for rotatably supporting a hook described later. A projecting hole 1224 for projecting a hook and a cam described later is provided at the bottom of the main body arcuate peripheral surface 1223.

  Furthermore, main body bearing portions 123 are formed at two positions on the left and right sides of the bottom surface of the main body base 12, and the bottom space 121 is disposed so as to sandwich the left and right sides. The main body bearing portion 123 forms a main body swinging hole 1232. On the other hand, a pedestal swing hole 2221 is also provided in the pedestal 20, and the main body swing hole 1232 and the pedestal swing hole 2221 are connected by a swing shaft 124. In this way, the main body base 12 is connected to the pedestal 20 so as to be swingable (that is, capable of tilting). Therefore, the main body arc-shaped peripheral surface 1223 is formed so as to form a part of a cylindrical peripheral surface centering on the swing shaft 124.

  The swing shaft 124 is formed of resin in the same manner as the main body base 12 and the pedestal 20. Further, the swing shaft 124 may be formed of a metal material. The structure can withstand abrasion and impact. Alternatively, either the main body swing hole 1232 or the base swing hole 2221 and the swing shaft 124 may be integrally formed. The integrally formed swing shaft 124 may be fitted into the other hole (the main body swing hole 1232 or the base swing hole 2221 which is not integrally molded) using the elasticity of the resin. The number of parts can be reduced and the structure can be reduced.

<Hook>
In FIG. 3, the hook 31 is formed in a shape branched from the main body portion into a substantially T shape. The tip of the hook 31 is a claw portion 311, and the claw portion 311 is formed in a triangular prism shape and has a function of engaging with a tooth row 224 described later. The left and right ends of the hook 31 are formed on the hook shaft 312. The hook shaft 312 is pivotally attached to the rotation hole 1222 formed in the bottom space 121 described above. When the hook 31 rotates about the hook shaft 312, the main body portion of the hook 31 approaches or separates toward the main body arcuate peripheral surface 1223.

  A hook contact portion 313 is provided at a portion where the main body portion approaches the main body arcuate peripheral surface 1223. The hook abutting portion 313 is a portion that abuts a cam 33 which will be described later. The hook abutting portion 313 has a substantially triangular cross section so that the hook 31 abutting on the cam 33 can be effectively rotated. Formed. The shape of the hook contact portion 313 is designed in order to make effective the timing, operation range, and the like regarding the rotation operation of the hook 31. Needless to say, the fact that the cross section is formed in a substantially triangular shape is an example of the first embodiment, and it should not be understood that the cross section is limited to a substantially triangular shape.

  Each hook shaft 312 is provided with a torsion coil spring 32. One end of the torsion coil spring 32 spans a predetermined position of the bottom space 121 (for example, to a hole provided in the main body arcuate circumferential surface 1223 or the edge of the protruding hole 1224), and the other end extends to the main body portion of the hook 31. It is. By the torsion coil spring 32, the hook 31 is urged toward the tooth row 224, and the claw portion 311 protruding from the protruding hole 1224 is pressed and urged to engage with the tooth row 224. That is, the torsion coil spring 32 functions as an urging member. Since the torsion coil spring 32 is disposed on the hook shaft 312, space can be saved. By appropriately adjusting the strength of the torsion coil spring 32, the urging force can be easily adjusted.

<Cam>
In FIG. 4, the cam 33 has a structure in which a rectangular columnar cam contact portion 331 and a substantially L-shaped cam arm portion 332 provided at both ends of the cam contact portion 331 are connected to form a substantially U shape. Have. A substantially L-shaped portion of the cam arm portion 332 forms a cam locking portion 333 for locking to the base 20. The cam contact portion 331 slides on the main body arcuate peripheral surface 1223.

  Each surface is processed so that moderate friction is generated between the main body arcuate peripheral surface 1223 and the cam contact portion 331 (surface finish). As the sliding mode, the main body arc-shaped peripheral surface 1223 slides with a frictional resistance that the cam contact portion 331 does not slide freely. When the cam contact portion 331 slides on the main body arcuate peripheral surface 1223, the cam locking portion 333 protrudes and moves in the direction of the pedestal 20 from the opening continuous with the protrusion hole 1224. In addition, you may provide an opening part as a protrusion hole of the cam latching | locking part 333 separately.

  The cam contact portion 331 also has a function of coming into contact with the hook contact portion 313 when sliding on the main body arc-shaped peripheral surface 1223. Since the inclination angle (sliding movement position and timing) at the time of contact has a great influence on the rotation operation of the hook 31, the hook 31 is effective in combination with the aforementioned substantially triangular cross section of the hook contact portion 313. The inclination angle of the cam abutting portion 331 is formed so as to perform a simple rotation operation.

  When the hook contact portion 313 comes into contact with the cam contact portion 331, the hook 31 comes into contact with the cam 33 by receiving an appropriate pressing force by the torsion coil spring 32, and the hook 31 rides on the cam 33.

  The hook 31 accommodated in the bottom space 121 described above, the biasing member of the hook 31, and the cam 33 are collectively referred to as a main body ratchet unit.

<Pedestal>
5 and 6, the pedestal 20 is integrally formed with a pedestal 21 that is a flat plate and a pedestal support 22 provided in front of the pedestal 21. The pedestal support portion 22 is formed in a space portion surrounded by a box shape of the rear portion 221 of the operator's back, the left and right side portions 222, and the front portion 223. A base rocking hole 2221 is formed in the front portion of the left and right side portions 222. A swing shaft 124 (see FIG. 2) is fitted to the base swing hole 2221 together with a main body swing hole 1232 (see FIG. 2), and the apparatus main body 10 is swingably mounted on the base 20. The periphery of the pedestal swing hole 2221 functions as a pedestal bearing that secures sufficient strength against the tilting operation of the apparatus main body 10, and is a pedestal bearing portion 2222.

  5 and 7, the inner (inner) surface of the rear portion 221 of the pedestal support portion 22 is a pedestal arc-shaped peripheral surface formed so as to form a part of a cylindrical peripheral surface centering on the swing shaft 124. 2211. In this way, the main body base 12 (particularly, the main body arc-shaped peripheral surface 1223 and the main body ratchet unit) that swings (tilts) with respect to the base 20 and the base arc-shaped peripheral surface 2211 are arranged to face each other.

  A tooth row 224 in which a plurality of teeth formed in a sawtooth shape along the pedestal arc-shaped peripheral surface 2211 is provided in the left and right central portions of the pedestal arc-shaped peripheral surface 2211. Therefore, the tip of the tooth row 224 is aligned along the pedestal arc-shaped peripheral surface 2211. The shape of the serrated teeth of the dentition 224 is that the claw portion 311 traces the slope of the sawtooth teeth when the locus of the inclination angle of the main body base 12 is increased, and the claw portion 311 is sawtooth when the main body base 12 descends. The tooth shape of the tooth row 224 is arranged so as to trace the horizontal surface of the tooth. In the case of the tooth row 224 of the first embodiment illustrated in FIG. 7, the number of teeth is 7 and the tooth horizontal surface 8, which means that it can be set to a horizontal state and seven stages of inclination angles.

  In addition, the base support part 22 is resin-molded integrally with the base 20 as a part of the whole base 20. On the other hand, the tooth row 224 and a cam control groove 226, which will be described later, require accurate finishing accuracy and are subject to repeated friction, so that surface wear resistance is also required. Therefore, the tooth row 224 and the cam control groove 226 may be formed of a material having excellent wear resistance and fitted to the base arcuate circumferential surface 2211.

  Furthermore, the downward extension surface of the tooth row 224 is formed with a space portion of a concave portion 225 formed in a curved surface 2251 continuous along the pedestal arc-shaped peripheral surface 2211. The curved surface 2251 is formed on the extension of the envelope that contacts the apex of the teeth of the tooth row 224. This is to ensure a smooth pivoting operation of the hook 31 when the hook 31 descends below the tooth row 224. Further, the space portion of the recess 225 is a space for securing a storage space for the main body ratchet unit when the apparatus main body 10 is leveled, and a storage space that can be used for wall hanging as described in the second embodiment. This is to ensure.

  In FIG. 6 and FIG. 7, cam control grooves 226 are provided in parallel on the left and right sides of the tooth row 224. When the apparatus main body 10 performs an inclination operation, the cam locking portion 333 protrudes from the protruding hole 1224 (opening) toward the base 20 and moves together with the apparatus main body 10. At this time, the cam control groove 226 functions as a guide groove for the cam locking portion 333.

  With this configuration, the cam control grooves 226 are positioned on both sides of the tooth row 224, so that the cam control groove 226 engages with the hook 31 and the tooth row 224, and the hook 31 moves to the cam 33. The right and left balance of the cam 33 in the ride-up operation can be kept good. Therefore, the locking operation of the cam 33 can be stabilized.

  Further, when the apparatus main body 10 is raised, an upper stage locking portion 2261 that restricts the upper limit of movement of the cam 33 is formed in the cam control groove 226. Even if the cam locking portion 333 engages with the upper locking portion 2261 and causes the apparatus main body 10 to increase the inclination angle, the cam 33 stops at the upper locking portion 2261.

  On the other hand, when the apparatus main body 10 is returned to the horizontal position, a lower locking portion 2262 that restricts the lower limit of movement of the cam 33 is formed in the cam control groove 226. The cam 33 stops at the lower locking portion 2262 even when the cam locking portion 333 is engaged with the lower locking portion 2262 and the apparatus main body 10 is returned to the horizontal position or the inclination angle is reversed for hanging. The upper locking portion 2261 and the lower locking portion 2262 block movement of the cam 33 by closing both ends of the cam control groove 226. That is, the cam 33 moves inside the apparatus main body 10 according to the inclination angle of the apparatus main body 10.

  The pedestal arc-shaped peripheral surface 2211, the tooth row 224, and the cam control groove 226 described above are collectively referred to as a pedestal ratchet unit. Furthermore, the pedestal ratchet unit and the aforementioned main body ratchet unit are collectively referred to as a ratchet portion 30.

  As described in detail above, according to the present invention, the mechanism such as the tooth row 224 and the hook 31 is housed in the housing (the ratchet portion 30). It becomes unnecessary. In this way, a telephone terminal device with a clean appearance and a thin main body can be obtained.

<Main body / pedestal engagement>
In FIG. 8, the positional relationship among the main body base 12, the pedestal 20, the hook 31, and the cam 33 in the above description will be described. First, the cam 33 is attached to the protruding hole 1224 of the main body base 12. Next, the hook shaft 312 of the hook 31 is pivotally attached to the rotation hole 1222 of the main body base 12, and the torsion coil spring 32 is hung on a predetermined position of the bottom space 121. Thus, the prepared main body base 12 mounts the swing shaft 124 to the main body swing hole 1232 together with the pedestal swing hole 2221, and the main body base 12 is pivotally attached to the pedestal 20.

  FIG. 9 shows the pedestal support part 22 so that the pedestal support part 22 can be seen by breaking a part of the bottom space part 121 in order to explain the engaged state of the main body base 12 and the pedestal 20. Furthermore, the prepared state of the main body base 12 will be described with reference to a cross-sectional view taken along the line CC of FIG.

  In FIG. 10, the cam 33 is stored in the bottom space 121 of the main body base 12 with the cam arm portion 332 facing downward. The cam locking portion 333 at the tip of the cam arm portion 332 protrudes from the protruding hole 1224 of the bottom space 121 and engages with the cam control groove 226 (see FIG. 5) of the pedestal support portion 22 when the main body base portion 12 is engaged with the pedestal 20. Match.

  Since there is moderate friction between the main body arcuate peripheral surface 1223 and the cam contact portion 331, the cam 33 is inclined and moved with the inclination of the main body base 12 (the pedestal) in the inclination range in which the main body base 12 can adjust the inclination angle. The cam 33 does not slide on the main body arcuate circumferential surface 1223.

  On the other hand, when the main body base 12 has an inclination angle exceeding the uppermost inclination, or when the main body base 12 has an inclination angle from the lowermost inclination to the initial position, the protruding cam engagement portion 333 is the upper engagement portion 2261 of the cam control groove 226 or the lower step. Lock to the locking portion 2262. Accordingly, the cam 33 stops moving (relative movement with respect to the pedestal 20), and the cam 33 slides and moves on the main body arcuate peripheral surface 1223 even if the main body base portion 12 tilts. That is, the cam 33 moves inside the apparatus main body 10 or stops according to the inclination angle of the apparatus main body 10.

  The hook 31 is attached in a state where the hook shaft 312 is inserted through the rotation hole 1222 of the bottom space 121 and the torsion coil spring 32 (not shown) is locked in the hole provided in the main body arcuate peripheral surface 1223. The hook 31 is biased toward the main body arcuate peripheral surface 1223 by the pressing bias of the torsion coil spring 32. The claw portion 311 of the hook 31 protrudes from the protruding hole 1224 similarly to the cam locking portion 333. When the main body base 12 is engaged with the pedestal 20, the protruding claw portion 311 is biased toward the tooth row 224 of the base arcuate circumferential surface 2211 and engages with the tooth row 224.

<Operating state>
The usage state of telephone device 1 according to Embodiment 1 of the present invention configured as described above will be described with reference to the drawings. 11 is a cross-sectional view showing the initial position, FIG. 11A is a view showing the position of the hook, and FIG. 11B is a view showing the position of the cam. In addition, the cross-sectional position represented by A and B represents the same position as the relationship between FIG. 6 and FIG. 7 in the same order, and the following cross-sectional views are the same.

  12A and 12B are cross-sectional views showing the lowest slope, FIG. 12A is a view showing the position of the hook, and FIG. 12B is a view showing the position of the cam. FIGS. 13A and 13B are cross-sectional views showing the uppermost slope, FIG. 13A is a view showing the position of the hook, and FIG. 13B is a view showing the position of the cam. FIG. 14 is a cross-sectional view showing the tilt release position, FIG. 14A is a view showing the position of the hook, and FIG. 14B is a view showing the position of the cam. FIG. 15 is a diagram illustrating a process of returning from the tilt release position to the initial position.

<Initial position>
Regarding the usage state of the telephone device 1, first, the device main body 10 is placed on a table horizontally and is set as an initial position. In FIG. 11, when the main body base 12 is horizontal as an initial position, the claw portion 311 of the hook 31 is not engaged with the tooth row 224, and the claw portion 311 is located at the front edge of the curved surface 2251. Further, the cam locking portion 333 of the cam 33 is locked to the lower locking portion 2262. Therefore, the cam 33 does not further descend from the position locked to the lower locking portion 2262 (see the position F in FIG. 15).

  The operator holds the display unit 111 side or the left and right side surfaces of the apparatus main body 10 (main body base 12), and gradually tilts the apparatus main body 10 (main body base 12). The main body base 12 starts to tilt (swing) about the swing shaft 124. As the main body base 12 is tilted (swinged), the hook 31 has the hook shaft 312 mounted on the rotation hole 1222, so that the hook 31 moves while sliding the claw portion 311 along the curved surface 2251. Start (see reverse movement of hook 31 from position F to position D in FIG. 15). As described above, since the cam 33 has a moderate friction between the main body arcuate peripheral surface 1223 and the cam contact portion 331, the cam 33 is camped in the cam control groove 226 as the main body base 12 is inclined (swinged). The ascending movement is started while sliding the locking portion 333.

<Inclined bottom>
If the operation of FIG. 11 is continued, the lowermost slope shown in FIG. 12 is reached. In FIG. 12, the claw portion 311 of the hook 31 engages with the first tooth (lowermost tooth) of the tooth row 224. Therefore, it is abbreviated as the lowermost inclination, and the inclination angle at that time is abbreviated as the minimum inclination position. Since the hook 31 is pressed and urged in the direction of the tooth row 224 by the torsion coil spring 32, the claw portion 311 is engaged with the tooth row 224 even if the operator depresses the main body base 12 or stops lifting. Is maintained. As a result, the apparatus main body 10 maintains the inclination of the initial position.

<Position adjustment>
The intermediate position from FIG. 12 to FIG. 13 is an adjustment range in which the inclination angle can be freely set. When the operator further pulls up the main body base 12, the hook 31 is pulled up along with the inclination of the main body base 12 as the rotation hole 1222 is raised. The claw portion 311 of the hook 31 traces the slope of the serrated tooth of the tooth row 224 and rises while getting over the tooth. The cam 33 starts to move upward while sliding the cam locking portion 333 in the cam control groove 226 due to friction with the main body arcuate peripheral surface 1223.

  When the operator tilts the main body base 12 to a desired tilt angle, the operator stops the pulling. Since the claw portion 311 of the hook 31 is pressed and urged by the torsion coil spring 32 in the direction of the tooth row 224, when it has passed the top of the sawtooth tooth of the tooth row 224, it is related to the horizontal surface of the tooth at that position. Match. When the tooth row 224 is in the middle of the slope of the sawtooth teeth, the tooth slope is lowered to reach the horizontal surface of the lower tooth, and the claw portion 311 engages with the lower tooth.

<Inclined top>
In this way, when the inclination angle of the apparatus main body 10 is increased, the uppermost inclination shown in FIG. 13 is reached. In FIG. 13, the hook 31 engages with the uppermost tooth of the tooth row 224. Therefore, it is abbreviated as the uppermost inclination, and the inclination angle at that time is abbreviated as the maximum inclination position. The pressing force applied to the hook 31 also functions in the same manner as described above. The cam 33 moves upward while sliding the cam locking portion 333 in the cam control groove 226 due to friction with the main body arcuate peripheral surface 1223, and the cam locking portion 333 moves to the vicinity of the upper locking portion 2261. ing.

  Thus, the hook 31 engages with a tooth at a desired position in the tooth row 224, so that the operation panel unit 11 can be set to an optimum inclination angle. The inclination angle of the main body base 12 is finely adjusted according to the number of teeth set in the tooth row 224 (that is, the number of division stages) from the lowest inclination (minimum inclination position) in FIG. 12 to the highest inclination (maximum inclination position) in FIG. It becomes possible to do.

<Inclination release position>
When the operator wants to release the inclination of the main body base 12 or returns it to the horizontal position, the main body base 12 is further pulled up to the inclination release position and inclined. An aspect of the tilt release position will be described with reference to FIGS. 14 and 15. When the main body base 12 is pulled up to the tilt release position, the cam locking portion 333 of the cam 33 is locked to the upper locking portion 2261 which is the cam movement upper limit point of the cam control groove 226, and the cam 33 stops moving. (See FIGS. 14B and 15A).

  On the other hand, when the main body base 12 is pulled up to the tilt release position, the hook 31 is pulled up by the lifting movement of the rotation hole 1222. At this time, the hook contact portion 313 of the hook 31 contacts the cam contact portion 331 of the stopped cam 33, and the hook 31 rides on the cam 33. When the hook 33 rides up, the hook 33 rotates about the hook shaft 312 against the pressing bias of the torsion coil spring 32 (see arrow D in FIG. 15B), and the claw portion 311 moves in the direction of arrow D. Rotates away from the dentition 224. Since the nail | claw part 311 leaves | separates from the tooth row | line | column 224, this is abbreviated as an inclination cancellation | release position.

  As described above, when the operation panel unit 11 is tilted beyond the uppermost tilt, the tilt cancellation position is reached and the tilt of the operation panel unit 11 can be canceled. Therefore, the operator can adjust the angle simply by tilting the apparatus main body 10 upward, and can easily operate with one hand.

<Inclination release process-descent start->
When the tilt release position described in FIGS. 14 and 15B is reached, the operator stops the operation of pulling up the main body base 12 and decreases the tilt angle of the main body base 12. Since the hook 31 is pressed and biased in the direction of the cam 33, the claw portion 311 hook 31 maintains the state of riding on the cam 33. In this way, the claw portion 311 of the hook 31 is lowered while maintaining the position away from the tooth row 224 (see FIGS. 15B to 15D).

  As described above, the cam 33 has a moderate friction between the main body arcuate peripheral surface 1223 and the cam abutting portion 331. Therefore, as the main body base 12 is lowered (decreasing the inclination angle), the cam locking portion 333 descends while sliding in the cam control groove 226. Thus, the main body base 12 continues to descend without being blocked while the claw portion 311 of the hook 31 is away from the tooth row 224. The process of continuing the lowering of the main body base 12 as described above is shown in FIGS. 15 (B) to 15 (D).

<Inclination release process-Cam stop->
In FIG. 15D, as described in the above initial position, the cam control groove 226 is formed with the lower locking portion 2262, so that the cam 33 that has continued to descend is locked by the lower locking portion 333. Engage with the portion 2262 to stop the downward movement.

  On the other hand, since the hook 31 continues to descend as the main body base 12 descends, the hook 31 cancels the riding on the stopped cam 33 and moves away (lowers) from the cam 33 (FIG. 15D). )reference). At this time, the claw portion 311 passes through the lowermost stage of the tooth row 224. As described above, since the curved surface 2251 is formed on the extension of the envelope contacting the apex of the teeth of the tooth row 224, even if the hook 31 moves further downward from the tooth row 224, it engages with the tooth row 224. There is nothing.

<Return to initial position>
The hook 31 rotates in the direction of arrow E (see FIG. 15E), and the claw portion 311 at the tip of the hook 31 slides on the surface of the curved surface 2251 (see FIGS. 15D to 15E). ). The operator continues to lower the main body base 12 and stops the lowering operation when the apparatus main body 10 returns to a substantially horizontal position. The hook 31 continues to move downward (rotates in the direction of arrow E), the cam 33 continues to stop, reaches the initial position shown in FIG. 15F, and stops the downward movement.

<Effect>
As described above in detail, according to the present invention, the initial position means that the hook 31 is separated from the cam 33 in the middle of lowering, and the hook 31 returns to a position where it can engage with the lowermost tooth of the tooth row 224. By this, it represents that the main body apparatus 10 is a position that returns to the minimum inclination angle with respect to the base 20. According to the present invention, the lowered main unit 10 is automatically set to the minimum inclination angle.

  The hook 31, the torsion coil spring 32 that is an urging member of the hook 31, and the cam 33 are accommodated in the bottom space 121 and constitute a main body ratchet unit. Further, the pedestal arc-shaped peripheral surface 2211, the tooth row 224, and the cam control groove 226 are accommodated in the pedestal support portion 22 and constitute a pedestal ratchet unit. The main body ratchet unit and the pedestal ratchet unit constitute a ratchet portion 30. As a result, there is no need to provide a post for determining the angle, a lever for operation, and the like, so that the phone apparatus 1 can be made thin and slim.

  Furthermore, the inclination of the apparatus main body 10 can be canceled by inclining beyond the uppermost stage. By the operation of releasing the inclination, the apparatus main body 10 can be returned to a substantially horizontal position with respect to the base 20. When the initial position is returned to the substantially horizontal position, the tilt angle can be set again.

  According to the present invention, the operator can adjust the angle simply by tilting the apparatus main body 10. The angle adjustment operation can be easily performed with one hand. The operator can adjust the tilt angle adjustment and the tilt angle cancellation by performing an operation of lifting a part of the main body.

<Example of initial position = minimum tilt position>
In the above description, it has been described that the initial position is at the horizontal position that is further lowered than the minimum tilt position. At this time, the number of teeth in the tooth row 224 is increased, and the tooth row 224 is further arranged below to obtain a new tooth row 224. When the mutual positions of the lower locking portion 2262 of the cam control groove 226, the hook contact portion, and the cam contact portion 331 are newly adjusted, the minimum inclination position can be set as the initial position.

  For example, in FIG. 15D, when the cam locking portion 333 of the cam 33 is engaged with the lower locking portion 2262 and the downward movement is stopped, the cam stopped like the hook 31 in FIG. The claw portion 311 can be configured to be positioned at the lowermost stage of the tooth row 224 by eliminating the riding on the position 33. Thus, the minimum inclination position can be set as the initial position.

  According to the present invention, the initial position is a position where the main body returns almost horizontally with respect to the pedestal when the hook is separated from the cam at a position where the initial position of the dentition is lowered in the middle of the lowering. It is a feature.

  According to this configuration, when the inclination is relaxed to the minimum inclination angle, the inclination angle can be set to the minimum inclination position. The operation can be easily performed with one hand, and the operator can adjust the tilt angle and cancel the tilt angle by lifting a part of the main body.

  As a result, the lowered main body can be returned to the substantially horizontal initial position. The pedestal is attached to the wall surface, and can be set to an initial position suitable for wall mounting.

<Other examples>
FIG. 16 is a diagram for explaining another example of the hook and the urging member. In this example, a plate spring is used as the urging member instead of the torsion coil spring 32. FIG. 16A is a perspective view of another hook, in which a part of the hook 31 formed of an elastic resin member is stretched to form a U-shaped leaf spring 314 integrally with the hook 31. Is.

  FIG. 16B is a diagram for explaining a mounting state of another hook, in which the tip of the leaf spring 314 is mounted over the opening edge of the bottom space 121 (for example, the edge of the protruding hole 1224). Represents a state. The U-shaped portion of the leaf spring 314 exhibits the elastic function of the elastic resin member, and can press and urge the claw portion 311 of the hook 31 toward the tooth row 224. By forming the leaf spring 314 integrally with the hook 31, the number of parts can be reduced and the cost can be reduced.

  In the above description, an example in which the ratchet portion 30 is provided at one position in the center has been described. However, the present invention is not limited to this example, and a plurality of ratchet portions 30 may be provided according to the bottom surface area and weight of the apparatus main body 10. The strength and durability of the main body bearing portion 123, the swing shaft 124, and the pedestal bearing portion 2222 can be increased, and a stable tilting operation can be ensured.

(Embodiment 2)
Next, another embodiment 2 of the present invention will be described. As described above as the first embodiment, the user can easily adjust the angle of the apparatus main body to a desired inclination. However, even when a third party lifts the apparatus main body, the inclination may easily change. This is because if the inclination is changed without knowing it, the user will feel uncomfortable.

  Then, the terminal device which can fix an apparatus main body to a desired inclination position is demonstrated using FIGS. 17-25. FIG. 17 is a view for explaining a mechanism for fixing the apparatus main body 10 in the inclined position in the second embodiment. FIG. 18 is a diagram for explaining the auxiliary lever 35. FIG. 19 is a perspective view of the lock lever 36. FIG. 20 is a diagram illustrating the lock lever 36. FIG. 21 is a perspective view of the hook 31. FIG. 22 is a diagram illustrating the hook 31. FIG. 23 is a cross-sectional view of the hook 31 of FIG. FIG. 24 is a diagram for explaining a hook mounting state. FIG. 25 is a diagram for explaining release of engagement at the initial position. In FIG. 17 to FIG. 23, the same components as those shown in FIG. 1 to FIG.

<Overview of mechanism for fixing at desired tilt position>
In FIG. 17, the telephone device 1 has a hook 31 having a lock button 34, an auxiliary lever 35, a lock lever 36, and an engaging portion 315 for the lock lever 36 with respect to the main body base 12 of the first embodiment. Are provided.

  Here, the lock button 34 is an operation means. The lock lever 36 is a second urging member that controls the engagement state between the hook 31 and the tooth row 224. The engaging portion 315 is a biasing engaging portion that receives control of the engagement state from the lock lever 36. Detailed operation of the engagement state control will be described later.

  The main body base 12, the pedestal 20, the bottom space 121, the main body bearing 123, the swing shaft 124, and the like, which are the structures of the main body base 12, described in FIGS. 1 and 2 have the same structure in the second embodiment. . They are denoted by the same reference numerals and description thereof is omitted.

<Lock button>
In the detailed view of the K section, the lock button 34 is a button having a substantially cubic shape. A hole having a shape along the outer peripheral wall portion 343 of the lock button 34 is provided in the main body base 12, and the lock button 34 is disposed so as to be fitted into the hole. A broken line portion is a portion protruding from the back surface 13 of the main body base 12 in FIG. The lock button 34 is supported by a guide 342. When the lock button 34 is pushed from the back surface 13 of the main body base 12, the lock button 34 is configured to move in the direction of arrow a while being supported by the guide 342.

  The lock button 34 is arranged so that a finger is placed on the upper right side of the apparatus main body 10 in FIG. When the user puts his hand to change the tilt position, the user can press it from the back surface 13 side. Since it is arranged on the back surface 13, it is excellent in design and looks good. In addition, when the user touches the apparatus main body 10, the finger is naturally applied to the button, so that the usability is improved.

  Further, in the detailed view of the K section, the lock button 34 has an inclined surface 341. At this time, a slight convex portion 344 is provided in the middle of the guide 342 in contact with the lock button 34. Then, when the lock button 34 is pushed in the direction a, it can be understood as a feeling that the lock button 34 is half-pressed. As a result, the lock button 34 can be pushed in two stages without being pushed all at once. In other words, it is possible to perform the push-separation with the first-pressed (half-pressed) position as the first operation position and the second-pressed position as the second operation position. The lock button 34 can be assigned three functions including the case where the lock button 34 is not pressed, thereby increasing usability.

<Auxiliary lever>
In FIG. 18A, the auxiliary lever 35 is a lever formed in a substantially rectangular parallelepiped. The auxiliary lever 35 forms an inclined surface 353 on the end point L side in contact with the lock button 34 in the detailed view of the K portion in FIG. The auxiliary lever 35 has a long hole 351 that fits and slides on the fixed shaft 356 of the fixture 355. Further, the auxiliary lever 35 forms a protrusion 352 on the end point M side.

  The auxiliary lever 35 is attached to the main body base 12 such that its long side is in the horizontal direction (parallel to the X axis). A spring 357 is installed in the gap between the back surface 354 of the auxiliary lever 35 and the main body base 12. The spring 357 is a compression spring, and one end is attached to the auxiliary lever 35 and the other end is attached to the main body base 12. The auxiliary lever 35 is formed to be movable left and right with respect to the main body base 12 by the fixture 355 in a state in which the spring 357 is biased in the arrow c direction (the lock button 34 direction). The auxiliary lever 35 is fitted to the fixed shaft 356 of the fixture 355 and moves to the left and right within the range of the long hole 351. The end point L when the auxiliary lever 35 is attached to the main body base 12 is disposed so as to contact the lock button 34.

<Lock lever>
FIG. 19A is a perspective view of the lock lever 36. FIG. 19B is a view of the lock lever 36 of FIG. The lock lever 36 is a lever formed in a thick plate shape. The lock lever 36 includes a rotation shaft 362 near the center. Further, an inclined groove 363 for contacting the protrusion 352 of the end point M of the auxiliary lever 35 is provided on the end point P side. An engagement shaft 361 is provided on the end point Q side. The end point Q has a substantially T-shaped shape in the reverse direction due to the engagement shaft 361.

  The lock lever 36 is fixed by a fixture 364 such that both end points of the lock lever 36 are rotatable about the rotation shaft 362 as a fulcrum. A spring 366 is installed in a gap between the back surface 365 near the end point Q of the lock lever 36 and the main body base 12. The spring 366 is a compression spring, and one end is attached to the lock lever 36 and the other end is attached to the main body base 12. The spring 366 is operably formed on the main body base 12 by the fixture 364 in a state where the end point Q side is urged in the direction of the arrow f. The lock lever 36 is attached to the main body base 12 so that the long side thereof is in the vertical direction. FIG. 20A is a view of the lock lever 36 of FIG. 19A viewed from the end point P direction.

  In FIG. 20A, the end point P of the lock lever 36 is provided with an inclined groove 363.

<Hook>
This will be described in detail based on the relationship between the engaging portions. FIG. 21 is a perspective view of the hook of the present embodiment. The hook 31 of the first embodiment is characterized in that an engagement portion 315 with the lock lever 36 is provided. The hook 31 is extended with respect to the hook shaft 312 in the direction opposite to the claw portion 311 to form an engaging portion 315 with the lock lever 36. The engagement hole 316 is a hole for engaging with the engagement shaft 361 of the lock lever 36. The opening 317 is formed by opening a part of the engagement hole 316 as shown in the figure. The torsion coil spring 32 is the same as that described in the first embodiment. In the second embodiment, the torsion coil spring 32 is referred to as a first biasing member in order to distinguish it from the second biasing member (lock lever 36).

  FIG. 22 is a front view of the hook 31 as viewed from the direction of arrows RR in FIG. A space portion surrounded by the engagement portion 315 with the lock lever 36 and formed by the opening 317 can engage the engagement shaft 361 at the end point Q of the lock lever 36. Since the engagement shaft 361 of the end point Q of the lock lever 36 is disengaged or pivotally attached through the portion where the width of the space portion is widened, the hook 31 and the lock lever 36 can be easily engaged and released. Can be. Furthermore, in the process of manufacturing and assembling the apparatus, extra man-hours for engagement are not taken, so that productivity can be increased.

  FIG. 23A is an SS cross-sectional view of FIG. The engagement portion 315 has an engagement hole 316 that engages the engagement shaft 361 at the end point Q of the lock lever 36. When the engagement shaft 361 is directed in the arrow i direction in the mounted state, the engagement hole 316 contacts the inner left surface (j surface) of the engagement hole 316 earlier than the inner right surface (k surface) in this drawing, and the arrow This is a structure formed so that the inner right surface (k surface) of the engagement hole 316 is in contact with the inner left surface (j surface) earlier than the inner left surface (j surface) when moving in the h direction. With this structure, when the engagement shaft 361 at the end point Q of the lock lever 36 moves in the direction of arrow i, the hook 31 is biased counterclockwise (q direction) about the hook shaft 312 as a fulcrum, and the engagement shaft 361 is moved to the arrow direction. When moving in the e direction, the hook 31 is urged clockwise (p direction) with the hook shaft 312 as a fulcrum. Detailed operation will be described later.

  FIG. 23B is a TT cross-sectional view of FIG. The engaging hole 316 of the engaging portion 315 has the structure as described above. In the TT sectional view, the opening 317 is provided on the inner left surface (j surface) of the engaging hole 316 in this figure. With this structure, when the engagement shaft 361 at the end point Q of the lock lever 36 is in the opening 317 of the hook 31, the engagement is released by the rotation of the hook 31 and the engagement hole 316 is released from the position. This operation will be described in detail later with reference to FIG.

<Operation of engaging part of lock button, auxiliary lever and lock lever>
18B, 18 </ b> C, and 18 </ b> D are diagrams for explaining in detail the operation by the contact between the lock button 34 and the auxiliary lever 35. In FIG. 18B, the lock button 34 is not yet pressed. When the lock button 34 is pressed with a finger from the back surface 13 of the main body base 12 from this state, the inclined surface 353 of the auxiliary lever 35 pushed in the direction of arrow a by the inclined surface 341 is in a direction in which the inclination of the contact portion releases the force. It moves in the direction of arrow b by the moving action.

  FIG. 18C shows a state where the lock button 34 is pressed one step (half pressed). Compared to the state of FIG. 18B, the auxiliary lever 35 has moved slightly in the direction of the arrow b. When the lock button 34 is further pressed, the auxiliary lever 35 further moves in the arrow b direction as shown in FIG.

  In the state of FIG. 18C or FIG. 18D, when the finger is released from the lock button 34, the auxiliary lever 35 is returned in the direction of the arrow c by the action of the spring 357 of the auxiliary lever 35 and the inclination of the contact portion releases the force. The lock button 34 is pushed back to the position shown in FIG. 18B by the action of moving in the direction.

  The engagement state of the lock lever 36 and the auxiliary lever 35 will be described with reference to FIGS. 19 (A), 20 (A), and 20 (B). The protrusion 352 of the auxiliary lever 35 abuts on the inclined groove 363 of the lock lever 36. Referring to FIG. 20B, when the lock button 34 is pushed with a finger, the auxiliary lever 35 moves in the arrow b direction. Then, the protrusion 352 also moves in the arrow b direction. At this time, since the protrusion 352 moves along the inclined groove 363 of the lock lever 36, the inclined groove upper surface 367 is pushed. The pressed inclined groove upper surface 367 moves the end point P in the direction of the arrow d in FIG. 20A with the rotation shaft 362 as a fulcrum by the action of the inclination moving in the direction of releasing the force. At this time, as shown in FIG. 19B, the engagement shaft 361 at the end point Q moves in the direction of arrow e.

  When the finger is released from the lock button 34, the end point P of the lock lever 36 moves in the direction of arrow f by the action of the spring 366 of the lock lever 36. Then, the auxiliary lever 35 and the lock button 34 are also pushed back by the action of the inclination of the contact portion moving in the direction of releasing the force.

<Operation of engaging portion between lock lever and hook>
FIG. 24 is a diagram for explaining a mounting state of the hook 31 according to the embodiment of the present invention, and shows a mounting state in which the hook 31 and the lock lever 36 are engaged.

  When the lock button 34 is not touched, that is, when the lock button 34 is not pressed with a finger, the engagement position between the hook 31 and the lock lever 36 is such that the engagement shaft 361 is at the end in the arrow i direction. In the U portion detailed view, the engagement shaft 361 in the relationship between FIG. 23A and FIG. 24A is at the r position of the engagement hole 316. A biasing force in the direction of arrow i is applied to the inner left surface (j surface) of the engagement hole 316 of the engagement portion 315. This urging pushes the inner left surface (j surface) of the engagement hole 316. That is, the hook 31 is biased to rotate counterclockwise (q direction) with the hook shaft 312 as a fulcrum.

  Then, the claw portion 311 of the hook 31 is already urged in the dentition direction by the coil spring 32 which is the first urging member, but the dentition is further increased by the urging transmitted from the lock lever 36 which is the second urging member. Biased in the direction.

  Thereby, when the main body is lifted, the claw portion 311 of the hook 31 cannot move in the direction opposite to the biasing direction. That is, unlike the first embodiment, the apparatus main body 10 can be fixed at the current desired tilt position.

  Therefore, even if a third party who is not the user of the apparatus lifts the apparatus main body 10, the inclination does not change easily, so that the user does not feel uncomfortable as described above and uses it comfortably. be able to. Moreover, since it can be realized by a mechanism inside the apparatus, it can be made clean in terms of design. In addition, the design can be easily changed because the engagement is maintained by the additional urging to the hook of the first embodiment.

  Further, if the engagement by the lock lever 36 is not maintained, the torsion coil spring 32 of the hook 31 needs to be provided with a very strong spring, but the present invention does not require such a strong spring.

  The hook 31 is positioned so that the position of the engagement shaft 361 when the finger is released from the lock button 34 is the uppermost position of the engagement hole 316 when the claw portion 311 is in contact with the tooth row 224. It may be designed to retain the engagement by exerting additional bias on the hook only when the body is lifted. This is because the tension applied to each component can be lowered during normal operation to reduce the burden on the component.

  When the lock button 34 is pushed down with a finger, as described above, the engagement position with the lock lever 36 is at the s position of the engagement hole 316 in FIG. A biasing force in the direction of arrow h is applied to the inner right surface (k surface) of the engagement hole 316 of the engagement portion 315. This biasing pushes the inner right surface (k surface) of the engagement hole 316. That is, the hook 31 is biased to rotate clockwise (p direction) about the hook shaft 312.

  The claw portion 311 of the hook 31 is already urged in the dentition direction by the coil spring 32 that is the first urging member, but this time, it is opposite to the dentition direction due to the urging transmitted from the lock lever 36 as described above. The direction is biased so as to cancel the bias by the coil spring 32. Then, the claw portion 311 of the hook 31 is separated from the tooth row 224 and the engagement is released.

  Thus, in Embodiment 1, the tilt cannot be released unless the main body base 12 is lifted to the tilt release position. However, in the present invention, the tilt angle can be adjusted downward without being lifted from the current desired position. Become. Therefore, even if a third party who is not the user of the apparatus lifts the apparatus main body 10, the inclination does not change easily. On the other hand, if the inclination is to be changed, the inclination can be easily achieved by pressing down the lock button 34 with a finger. Because the angle can be changed, it can be used comfortably.

  When the lock button 34 is pushed only one step with a finger (half-pressed), the engagement position with the lock lever 36 is at the position t of the engagement hole 316 in FIG. No bias is applied to any surface inside the joint hole 316. That is, the claw portion 311 of the hook 31 is only urged in the dentition direction by the coil spring 32 that is the first urging member.

  Thus, the operation is the same as in the first embodiment. That is, when the user pulls up the main body base 12, the hook 31 is pulled up along with the inclination of the main body base 12 as the rotation hole 1222 rises. Then, since it is only urged by the coil spring 32, the claw portion 311 of the hook 31 traces the slope of the sawtooth teeth of the tooth row 224 and moves up over the teeth. When the user tilts the main body base 12 to a desired tilt angle and stops the pulling, the claw portion 311 of the hook 31 is pressed and urged by the torsion coil spring 32 in the direction of the tooth row 224. If the apex of the tooth of the shape is overcome, it engages the horizontal surface of the tooth at that position. When the tooth row 224 is in the middle of the slope of the sawtooth teeth, the tooth slope is lowered to reach the horizontal surface of the lower tooth, and the claw portion 311 engages with the lower tooth. Thus, the hook 31 engages with a tooth at a desired position in the tooth row 224, so that the operation panel unit 11 can be set to an optimum inclination angle.

<Initial position>
Next, the case where the main body base 12 is lowered toward the initial position will be described with reference to FIG. When the main body base portion 12 is pulled up to the tilt release position or the lock button 34 is pushed down with a finger, the claw portion 311 of the hook 31 comes into contact with the curved surface 2251. If the descent continues further, the hook shaft 312 descends, but the claw portion 311 has already come into contact with the curved surface 2251 and thus escapes in the direction of the arrow u due to the reaction from the curved surface 2251. For this reason, the hook 31 rotates clockwise around the hook shaft 312. Then, the engagement shaft 361 at the end point Q of the lock lever 36 passes through the opening 317 of the engagement hole 316 of the engagement portion 315 with the lock lever 36 of the hook 31. Then, the lock lever 36 is released from the hook 31.

  Even when the apparatus main body 10 is set to the initial position by detaching the lock lever 36 from the hook 31, the thickness of the apparatus can be reduced because the hook can be rotated to a nearly horizontal state, and the usability is improved. Also, the design is excellent. In particular, the functionality increases when used on a wall.

<Others>
The engagement shaft 361 of the end point Q of the lock lever 36 may be provided only in one direction, and the engagement portion 315 of the hook 31 may be provided only in the same direction as the engagement shaft 361, and the engagement portion may be provided in one place. In this case, the substantially L-shaped space portion formed by the substantially L-shaped end point Q and the opening 317 is engaged or disengaged. The width of the parts can be narrowed and the apparatus can be miniaturized.

  In the present embodiment, it has been described that the hook 31 is urged toward the tooth row 224 by the urging of the lock lever 36 when the lock button 34 is not pressed with a finger, but the torsion coil spring 32 is simply urged in the urging direction. You may keep it from being pushed back from. This is because the claw portion 311 of the hook 31 cannot be lifted while tracing the tooth row 224 as in the first embodiment when the main body is lifted unless pushed back from the urging direction.

  In the present embodiment, the hook 31 is extended in the direction opposite to the claw portion 311 with respect to the hook shaft 312, and the engaging portion with the lock lever 36 is formed. An engaging portion 315 with the lock lever 36 may be formed between the shaft 31 and the hook shaft 312.

  Since the hook 31 is not extended, the thickness of the apparatus can be reduced, and the usability is improved. Also, the design is excellent. In this case, since the engaging portion of the claw portion 311 serving as the action point and the lock lever 36 serving as the power point is on the same side with respect to the hook shaft 312 serving as the fulcrum, the urging direction from the lock lever 36 to the hook 31 is set to This is because the same effect as described above can be obtained by reversing that described above.

  In addition, the arrangement of the lock button 34 has been described as being arranged so as to be pressed from the back surface of the main body base 12, but it may be arranged on another surface. This is because the same effect can be obtained if the urging force from the lock lever 36 to the hook 31 works regardless of the arrangement of the lock button 34. Thus, since there is a degree of freedom in the arrangement of the lock button 34, it can be arranged according to the design and functionality.

  In addition, the lock button 34 has been described so that it can be pressed in two steps by providing a slight convex portion as a resistor in the middle of the guide 342 in contact with the lock button 34, but a button having a two-step mechanism is a component. It may be used as Increased reliability.

  Further, the auxiliary lever 35 may be directly operated without having the lock button 34 as a component. For example, if the auxiliary lever 35 is extended to the right and protrudes from the right side surface of the main body base 12, the operation can be changed to push the auxiliary lever 35 directly. In this way, the number of parts can be reduced and the mechanism can be simplified, so that the reliability is increased.

  Further, although the lock lever 36 has been described as having the spring 366 installed in the gap with the main body base 12, the spring 366 may not be provided as a component. This is because both the end points of the lock lever 36 are determined by the engagement with the hook 31 and the auxiliary lever 35, and thus are equal to being formed in a state of being biased by the spring 366.

<Effect>
As described in detail above, according to the present invention, the apparatus main body 10 can be fixed at the current desired tilt position. Therefore, even if a third party who is not the user of the apparatus lifts the apparatus main body 10, the inclination does not change easily, so that the user does not feel uncomfortable as described above and uses it comfortably. be able to. On the other hand, when it is desired to change the inclination, the inclination angle can be easily changed by pressing the lock button 34 with a finger, so that it can be used comfortably.

  Furthermore, according to the present invention, since it can be realized by a mechanism inside the apparatus, the design can be made clean. Furthermore, according to the present invention, the engagement can be maintained by the additional urging to the hook of the first embodiment, so that the design can be easily changed. Furthermore, according to the present invention, the inclination angle can be adjusted downward without being pulled up from the current desired position.

  According to the present invention, the hook 31, the torsion coil spring 32 of the hook 31, and the cam 33 are accommodated in the bottom space 121 and constitute a main body ratchet unit. Further, the pedestal arc-shaped peripheral surface 2211, the tooth row 224, and the cam control groove 226 are accommodated in the pedestal support portion 22 and constitute a pedestal ratchet unit. The main body ratchet unit and the pedestal ratchet unit constitute a ratchet portion 30. As a result, there is no need to provide a post for determining the angle, and the telephone device 1 can be made thin and slim with a clean appearance.

  Furthermore, the inclination of the apparatus main body 10 can be canceled by inclining beyond the uppermost stage. By the operation of releasing the inclination, the apparatus main body 10 can be returned to a substantially horizontal position with respect to the base 20. When the initial position is returned to the substantially horizontal position, the tilt angle can be set again.

  According to the present invention, the user can adjust the angle simply by tilting the apparatus main body 10. The angle adjustment operation can be easily performed with one hand. The user can adjust the tilt angle adjustment and the tilt angle cancellation by performing an operation of lifting a part of the main body.

  In the present invention, since the operation panel can be easily set to a desired inclination and the engaged state is maintained after adjusting to a desired angle, the operation panel can be installed on a tabletop or a wall for viewing and operating the display. It is suitable for a terminal device with improved performance.

  The embodiment of the present invention has been described by taking a telephone device as an example. However, the present invention is not limited to a telephone device, and the contents of the present invention are widely used for a terminal device that is installed on a tabletop or a wall and is improved in operability for human viewing and operation. There is no need to repeat that what can be done.
