Description

  The present invention relates to an apparatus with a rotating body in which a rotating body is rotatably attached to a bottom surface of an apparatus main body.

  2. Description of the Related Art Conventionally, an apparatus with a rotating body is known in which a rotating body is rotatably attached to the bottom surface of the apparatus main body. For example, in Patent Document 1 below, a stand member (rotating body) is rotatably provided on the bottom surface of the apparatus main body, and the state can be changed between a horizontally installed state and a standing state. A connection cord extending from a concave accommodation space provided on the bottom surface of the apparatus main body is accommodated in the accommodation space, and a stand member placed in a horizontal state functions as the lid. Further, when the stand member is set in the standing state, the apparatus main body is held at an angle suitable for use (keyboard performance).

  In this type of device that supports the apparatus main body in a state where the rotating body is displaced in the opening direction, the position of the rotating body in the opening direction is normally restricted by some kind of restricting member such as a stopper.

Japanese Patent No. 3896934

  However, if the rotating body is restricted to the limit position in the opening direction and receives a very strong force in the opening direction, the rotating body may be damaged, or the rotating mechanism that supports the rotating body can be broken. There is a risk of doing so. For example, although the above-mentioned Patent Document 1 is applied to a musical instrument, it is considered that if the musical instrument is strongly pressed down in a standing state, the stand member and its rotating mechanism are damaged.

  Such a possibility of failure around the rotating body due to overload is not limited to electronic devices, and can be considered in any apparatus with a rotating body. Further, the rotating body is not limited to the lid body or the stand. For example, in a music stand apparatus, if an overload is applied in the opening direction with a turnable music stand standing, there is a risk of damage.

  The present invention has been made to solve the above-described problems of the prior art, and its purpose is to prevent the rotating body from being detached from the main body when it is overloaded in the opening direction, thereby preventing damage. The object is to provide a moving device.

One is a shaft portion (44) and the other is a bearing hole (29). By inserting the shaft portion into the bearing hole, the apparatus main body and the rotating body become relatively rotatable, and the rotation When the moving body further receives a force in the opening direction in the standing state, the rotating body The abutting portion (P2) between the free end and the rotation center (C0) abuts against the abutted portion (P1) of the apparatus main body, and the urging force with the abutted portion as a fulcrum is A chamfered portion (47) is formed on one end of the shaft portion in the radial direction at the edge portion (44a) of the shaft portion, and the contact portion is configured to act on the engaging portion. When the rotating body further receives a force in the opening direction while being in contact with the contacted portion, the rotating body is elastically deformed due to the biasing force, and follows the direction (F1) of the biasing force. the relative separation of the shaft portion relative to the bearing bore starts from the chamfered portion of the edge of the distal end of the shaft portion is configured soon as the shaft portion may be disengaged with respect to said bearing hole and said Of the main body or the rotating body, the one having the bearing hole is inserted adjacent to the bearing hole. A first meat part protrudes on the pull-out side in the direction, and the one of the apparatus main body or the rotating body that has the shaft part is integrated with the shaft part on the insertion side in the insertion / extraction direction of the shaft part. Before the chamfered portion of the shaft portion starts to be detached from the bearing hole along the direction of the urging force in a process in which the protruding portion is protruded and the rotating body further rotates in the opening direction in the standing state. In this stage, the rotating body elastically deforms as the protruding portion rides on the pulling side with respect to the first meat part, and the device body or the rotating body further includes the bearing hole. Next to the bearing hole, a second meat portion projects from the pull-out side at a distance from the first meat portion, and the rotating body rotates in the opening direction from the inverted state. In the process, the protruding portion is connected to the side of the second meat portion. The rotating body is in the standing state when it is positioned between the first meat part and the second meat part after getting over .

  Preferably, the chamfered portion includes a straight line (L1) connecting the contact portion (P2) and the rotation center in a state where the contact portion is in contact with the contacted portion, and an axis of the shaft portion. Is located on a virtual straight line (L2) perpendicular to the center and passing through the center of rotation.

  Preferably, the ridge line portion (49a) that engages with the first meat portion when riding on the first meat portion among the protrusions is chamfered or rounded.

  Preferably, a concave portion (21) is formed on a surface of the apparatus main body on which the rotating body is disposed, and the engaging portion and the engaged portion are engaged in the concave portion.

  In addition, the code | symbol in the said parenthesis is an illustration.

According to the first aspect of the present invention, when the rotating body is overloaded in the opening direction, it can be removed from the main body to prevent damage. Further, when the rotating body is excessively rotated in the opening direction, preliminary elastic deformation can be applied to the rotating body before the chamfered part starts to be detached, so that the rotating body can be easily detached from the main body when overloaded. Moreover, the stable positioning to a standing state can be performed.

According to the third aspect , preliminary elastic deformation can be smoothly applied to the rotating body.

According to the fourth aspect , the shaft portion and the bearing hole are not exposed, and the durability of the rotation mechanism portion is enhanced.

Hereinafter, the front and rear directions of the lid 40 are referred to based on the closed state of the lid 40. Also, the surfaces that are the outer side and the inner side in the closed state are referred to as an outer surface and an inner surface, respectively.

  First, as shown in FIG. 2, an accommodation recess 21 that is recessed upward is formed in the right half of the front portion 20 a of the bottom surface 20 e of the device main body 20. A connecting portion 25 which is a USB female terminal is provided on a wall portion 24 which is a vertical central wall constituting the left end of the housing recess 21 (see also FIG. 1B). The male terminal portion 31 of the connection cord 30 can be connected to the connection portion 25. In the connection state shown in FIG. 2, signals are exchanged between the electronic device 12 and the personal computer 11 by connecting a terminal (not shown) at the tip of the cord portion 32 of the connection cord 30 to the terminal of the personal computer 11. It becomes possible.

  The lid body 40 is rotated by an opening / closing operation, and is folded between the device body 20 and covers the housing recess 21, and the lid body 40 is erected with respect to the device body 20 and functions as a standing stand. It is possible to change. The inverted state corresponds to the closed state, and the standing state corresponds to the open state. In the standing state, the leg portions bt1 and bt2 made of elastic resin are provided at the left and right end portions of the free end portion 40a of the lid body 40 on the placement surface (not shown) at the rotation position shown in FIG. Comes into contact with each other and the device body 20 is supported. The leg portions bt1 and bt2 also serve to prevent the device main body 20 from slipping when standing.

  A first cord outlet 22 is formed as a first recess connected to the right side of the deepest portion 21a in the housing recess 21 (see also FIG. 4B). The first cord outlet 22 is formed as a recess that is shallower than the deepest portion 21a, and opens to the right portion 20d of the device main body 20. Used to derive to the right.

  In addition, a second cord outlet 23 is formed in the front portion of the first cord outlet 22 as a second recess connected to the first cord outlet 22. The second cord outlet 23 opens to the front portion 20a of the device main body 20, and is used to lead the cord portion 32 forward.

  A stepped portion 21b is formed at a position shallower than the portion 21a so as to connect to the right rear portion of the deepest portion 21a. A rotation mechanism M that allows the lid 40 to rotate with respect to the device main body 20 is disposed at a position higher than the bottom surface 20 e in the stepped portion 21 b of the recess 21. The rotating mechanism M includes a receiving mechanism MU (FIG. 5A) configured on the device main body 20 side and a shaft-side mechanism MJ (FIGS. 3 and 5) configured on the lid 40 side. (B)).

  As shown in FIG. 3A, the lid 40 is integrally formed of resin or the like with the left-right direction as the longitudinal direction. A shaft side mechanism MJ is provided at each rear part of the left part 40b and the right part 40c of the lid 40. The front part of the plate part 41 between the left part 40b and the right part 40c becomes the free end part 40a when the lid body 40 rotates. An insertion portion 42 is formed by a notch at a position slightly to the left of the free end portion 40a of the plate portion 41 (see also FIG. 1B). The insertion portion 42 is mainly used to lead the cord portion 32 of the connection cord 30 rearward when the lid body 40 is in the standing state. For example, after passing through the insertion portion 42, it can be led out in either the rear or left and right directions.

  The free end portion 40a of the plate portion 41 is provided with two protrusions 43 having claw portions 43a. The leg portions bt1 and bt2 are covered and pressure-bonded to the protrusion 43. On the inner surface side of the right portion 40c of the lid 40, a concave portion 48 that is recessed downward is formed (FIGS. 3C and 3D). The lid 40 is symmetrical except for the insertion portion 42.

  FIG. 4A is an enlarged bottom view of the vicinity of the right rotation mechanism M in the closed state of the lid 40. FIG.4 (b) is sectional drawing which follows the AA line of FIG.1 (b).

  As shown in FIG. 4 (b), when the lid 40 is in the inverted state, the device body 20 has a first gap between the front portion of the right portion 20d of the device body 20 and the right portion 40c of the lid body 40. A vertical gap S <b> 1 is formed between the one cord outlet 22 and the recess 48 of the lid 40. When the lid 40 is in the inverted state, the cord portion 32 of the connection cord 30 can be led out in a desired direction. First, the cord portion 32 can be led out from the gap S1 to the right via the first cord outlet 22. Alternatively, it can be led forward from the gap S1 through the first cord outlet 22 and the second cord outlet 23 (FIG. 2). Any of these derivation modes can be selected.

  Here, as shown in FIG. 1B, the straight line L3 connecting the connecting portion 25 and the gap S1 is parallel to the left-right direction, and the first cord outlet 22 opens on the extension of the straight line L3. Yes. On the other hand, the second cord outlet 23 opens in a direction substantially orthogonal to the straight line L3. Since the opening direction of the first cord outlet 22 and the second cord outlet 23 is clearly different (90 °), the user can select the derivation direction according to the usage mode, and in routing and handling the cord portion 32 A high degree of freedom is obtained.

  On the other hand, when the lid 40 is in the standing state, if the cord portion 32 is inserted into the insertion portion 42 (FIG. 2), the cord portion 32 is guided backward without passing the left or right side of the lid 40. You can also. The cord portion 32 can be guided in the right or left direction through the insertion portion 42 and between the leg portions bt1 and bt3 (FIG. 1b) or between the leg portions bt2 and bt4 (FIG. 1b). Thus, by obtaining various options for the derivation route and direction, it is possible to increase the degree of freedom in the derivation direction and improve the convenience for the user. Moreover, the code | cord | chord part 32 can also be wound around the cover body 40 made into the standing state.

  FIGS. 5A and 5B are perspective views of the right-side receiving mechanism MU and the shaft-side mechanism MJ, respectively. Since the left and right turning mechanism M (the receiving side mechanism MU and the shaft side mechanism MJ) are bilaterally symmetrical, the description will mainly be made on the right side.

  As shown in FIGS. 3B to 3D, FIG. 4A, and FIG. 5B, in the shaft-side mechanism portion MJ, the first shaft portion 44 and the second shaft portion 45 that are both concentric are integrated. Is formed. The second shaft portion 45 protrudes rightward from the rear portion of the right portion 40 c, and the first shaft portion 44 having a smaller diameter than the second shaft portion 45 protrudes rightward from the second shaft portion 45. A protrusion 49 is formed integrally with the rear portion of the outer periphery of the second shaft portion 45 on the rear end face 40b1 of the right portion 40c. Chamfering or R-shape is applied to the ridge line portion 49a on the inner surface side of the lid body 40 in the protrusion 49 (FIG. 5B).

  A chamfered portion 47 is formed on one edge of the first shaft portion 44 in the radial direction (the inner surface side of the lid body 40) at the edge portion 44a of the first shaft portion 44 (FIG. 5B). In the closed state of the lid 40, the chamfered portion 47 faces rightward and upward, and the ridgeline formed by the tip surface of the first shaft portion 44 and the chamfered portion 47 is substantially parallel to the front-rear direction (FIG. 3C )).

  As shown in FIG. 4A and FIG. 5A, the receiving side mechanism unit MU includes a first meat part 26 and a second part formed integrally with the step part 21b with a space in the front-rear direction. And a meat part 27. Further, a tapered surface 28 is formed on the right side of the stepped portion 21b along the oblique vertical direction, and a circular bearing hole 29 into which the first shaft portion 44 is inserted is formed on the tapered surface 28. The center line of the bearing hole 29 is along the left-right direction. In the bearing hole 29 of the right receiving side mechanism MU, the right side (left side in FIG. 4A) is the insertion side in the insertion / extraction direction of the first shaft portion 44, and the left side (right side in FIG. 4A). Is the unplugged side. Each of the first meat portion 26 and the second meat portion 27 protrudes from the tapered surface 28 toward the drawing side and is adjacent to the bearing hole 29.

  FIG. 6 is a schematic view of the right turning mechanism M viewed from the inner left side (direction D1 in FIG. 4A). 6A and 6B show a closed state (inverted state) and an open state (upright state) of the lid 40, respectively. FIG. 6C shows a state (overload state) in which the lid 40 is rotated by receiving a force in the opening direction from the open state. As will be described later, when the lid body 40 is further overloaded in the opening direction from the standing state, the first shaft portion 44 is detached (disengaged) from the bearing hole 29, so that the device body 20 and the lid body 40 are Damage is to be avoided.

  In the left and right turning mechanism M, the first shaft 44 is inserted and engaged with the bearing hole 29, and the lid 40 is assembled to the device main body 20. As shown in FIG. 4A, the second shaft portion 45 is over the first meat portion 26 and the second meat portion 27 in the axial direction of the first shaft portion 44 when the lid body 40 is in the inverted state. Wrapping. And the outer peripheral surface of the 2nd axial part 45, the concave curved surface 26a of the 1st meat part 26, and the concave curved surface 27a of the 2nd meat part 27 are opposing sliding contact. (FIG. 5A, FIG. 6A).

  With reference to FIG. 6, the transition in the rotation stroke of the lid 40 will be described. In FIG. 6, the clockwise direction and the counterclockwise direction are the closing direction and the opening direction of the lid 40, respectively. First, in the inverted state (FIG. 6A), the ridge line portion 49a of the projection portion 49 and the tapered surface 49b connected to the lower surface 27b of the second meat portion 27 with the projection portion 49 facing rearward. (Fig. 5 (b)) is on board. In this state, as shown in FIG. 4A, there is a slight gap between the end surfaces 26c and 27c (FIG. 5A) of the meat portions 26 and 27 and the end surface 40b1 of the right portion 40c at the rear portion of the lid body 40. Thus, the gap portion CL can be generated, and the lid body 40 is not restricted in the left-right direction and can be slightly displaced.

  By the way, when changing from the open state to the closed state (inverted state), a click feeling is obtained when the protruding portion 49 rides on the second meat portion 27, and at the same time, the lid body 40 is attached to the device main body 20 by snap fitting. It is easily locked in the closed state. In addition, it is not essential that the gap CL is generated, and the end surface 40b1 and the end surfaces 26c and 27c may be in sliding contact with each other.

  When the lid 40 receives a certain force or more in the opening direction from this inverted state, it starts to rotate in the opening direction. In the rotation stroke, the protruding portion 49 gets over the second meat portion 27 on the pulling side, and the distal end surface 49c and the end surface 27c of the protruding portion 49 are elastically slidably in contact with each other to further displace. And the first meat part 26, the lid 40 is in a standing state (FIG. 6B).

  The same operation occurs simultaneously in the left rotation mechanism M. In a state in which the protruding portion 49 rides on the second meat portion 27, the lid body 40 is elastically deformed in a direction in which the left and right shaft side mechanism portions MJ (FIG. 3A) approach each other. This elastic deformation includes not only deformation of the plate portion 41 (mainly vertical deformation), but also deformation of the portion extending in a cantilevered state behind the left portion 40b and the right portion 40c inward in the left-right direction (extraction side). Is also included.

  Further, when the protrusion 49 gets over the second meat portion 27, the ridge line portion 49a of the protrusion 49 that first engages with the second meat portion 27 is chamfered or rounded as described above. The ride-up operation is smooth. In the state where the protrusion 49 is located between the second meat portion 27 and the first meat portion 26, the elastic deformation of the lid body 40 is eliminated, and the standing state is stabilized. At this time, it is not essential that the elastic deformation is completely eliminated.

  When the cover body 40 receives a greater force in the opening direction in the standing state and becomes overloaded, the contact portion P2 of the cover body 40 is brought into contact with the device body 20 as shown in FIG. It strongly abuts against the part P1. The contact portions P <b> 2 and P <b> 1 may be lightly contacted in advance by the weight of the device body 20. The contact portion P2 is a portion between the rotation center C0 passing through the axis of the first shaft portion 44 and the free end portion 40a. In this state, the urging force with the abutted portion P <b> 1 as a fulcrum acts on the first shaft portion 44. The direction of this urging force is the F1 direction and can be increased by the lever principle.

  Here, as shown in FIG. 6C, a straight line connecting the contact portion P2 and the rotation center C0 in a state where the contact portion P2 is in contact with the contacted portion P1 is defined as L1, and the rotation center C0. A virtual straight line that passes through the straight line L1 and is perpendicular to the axis of the first shaft portion 44 is denoted by L2. The chamfered portion 47 is formed on the virtual straight line L2 in a state where the contact portion P2 is in contact with the contacted portion P1. In the present embodiment, immediately after the first shaft portion 44 is detached from the bearing hole 29, the chamfer forming direction F2 and the F1 direction are substantially the same direction, and the separation is smooth. However, the chamfer forming direction F2 may be coincident with the F1 direction.

  In the rotation process of the lid body 40 in the opening direction, the protrusion portion 49 rides on the pulling side with respect to the first meat portion 26 from before the urging force is applied to during the operation, so that the lid body 40 is elastic. Deform. Also in this case, the ridge line portion 49a of the protrusion 49 is chamfered or rounded, so that the riding operation is smooth. The elastic deformation at this time can be said to be preliminary elastic deformation with respect to the elastic deformation necessary for the first shaft portion 44 to come out of the bearing hole 29. The elastic deformation referred to here is not only the deformation of the plate portion 41, but also the left and right direction of the portion extending in a cantilevered manner behind the left portion 40b and the right portion 40c, as in the case of riding on the second meat portion 27. The deformation to the inner side (extraction side) is also included.

  If the urging force is further increased in the state of the preliminary elastic deformation, the elastic deformation of the lid body 40 is further increased, and the first shaft portion 44 is finally removed from the bearing hole 29. That is, first, the chamfered portion 47 is completely fitted into the bearing hole 29 from the inverted state to the standing state (see FIG. 4A). However, when the overload is applied and the protruding portion 49 rides on the first meat portion 26, the first shaft portion 44 comes slightly out of the bearing hole 29 due to preliminary elastic deformation of the lid 40.

  The first shaft portion 44 is exposed from the bearing hole 29 and receives the urging force in the F1 direction, so that the lid body 40 is further elastically deformed due to the urging force. When attention is paid to the direction (position in the rotation direction) of the chamfered portion 47, the chamfered portion 47 is located in the F1 direction in the overload state (FIG. 6C). Accordingly, the separation of the first shaft portion 44 from the bearing hole 29 along the F1 direction starts from the chamfered portion 47 of the edge portion 44a at the tip of the first shaft portion 44. Then, the first shaft portion 44 is eventually detached from the bearing hole 29 in the F1 direction.

  The detachment of the first shaft portion 44 from the bearing hole 29 occurs almost simultaneously in the left and right turning mechanism portions M, whereby the lid body 40 is completely removed from the device main body 20 without difficulty.

  According to the present embodiment, when the cover body 40 receives a force that causes an overload in the opening direction from the standing state, the first shaft portion 44 is detached from the bearing hole 29 from the chamfered portion 47, Since the lid 40 is detached from the device main body 20, damage to the electronic device 12 can be prevented.

  In particular, since the chamfered portion 47 is located in the direction of application of the urging force with the abutted portion P1 as a fulcrum (F1 direction: on the imaginary straight line L2), the positional relationship in which the chamfered portion 47 is most likely to be detached from the bearing hole 29 during overload. It is possible to leave without difficulty.

  Here, the cover body 40 is in a position rotated by an obtuse angle of 90 ° or more with respect to the inverted state in the standing state. In most cases, it is assumed that the device main body 20 receives a pressing force from above in the standing state. In such a case, the lid body 40 is further subjected to a load in the opening direction from the standing state. Accordingly, the present invention is an effective measure for situations where damage is most likely to occur. However, the application of the present invention is not excluded for an apparatus including a rotating body that has an acute angle in a standing state with respect to a standing state.

  Furthermore, in the process in which the lid body 40 is further rotated in the opening direction in the standing state, the protrusion 49 runs on the pulling side with respect to the first meat part 26 at a stage before the chamfered part 47 starts to be detached. Thus, the lid 40 is elastically deformed preliminarily. Thereby, it connects smoothly to the operation | movement to the elastic deformation for detachment | leave, and the cover body 40 becomes easy to remove | deviate from the apparatus main body 20 at the time of an overload. In addition, since the ridge line portion 49a of the protrusion 49 is chamfered or rounded, the operation of riding on the first meat portion 26 and applying preliminary elastic deformation to the lid body 40 becomes smooth.

  Further, in the process of turning the lid 40 in the opening direction, the protruding portion 49 is in the standing state with the projection 49 positioned between the second meat portion 27 and the first meat portion 26. Can be positioned stably. Moreover, the first meat portion 26 plays a role of regulating the position of the lid 40 in the opening direction in the standing state in addition to the role of causing the lid 40 to undergo preliminary deformation for detachment (the opening direction beyond that). It also serves as a stopper function that does not displace

  Further, the chamfered portion 47 is not exposed from the bearing hole 29 until immediately before separation. That is, the lid 40 is completely fitted into the bearing hole 29 in the stroke from the inverted state to the standing state. Thereby, the rotation operation | movement of the cover body 40 can be maintained stably.

  Further, the rotation mechanism part M is disposed in the step part 21b of the housing recess 21, and the first shaft part 44 of the shaft side mechanism part MJ and the bearing hole 29 of the receiving side mechanism part MU are engaged in the step part 21b. Therefore, the first shaft portion 44 and the bearing hole 29 are not exposed, and the rotation mechanism portion M is protected and durability is increased. Moreover, since the rotation mechanism M is disposed at a position higher than the bottom surface 20e, the height of the device main body 20 can be kept low when the lid 40 is in the inverted state.

  According to the present embodiment, when the lid 40 is in the inverted state, the cord portion 32 of the connection cord 30 is led out from the first cord outlet 22 through the gap S1, or the gap S1. Can be selected from the first cord outlet 22 and the second cord outlet 23. On the other hand, when the lid 40 is in the standing state, the cord portion 32 can be led out through the insertion portion 42 and can be passed through the portion other than the insertion portion 42. Therefore, the degree of freedom in the direction in which the connecting cord 30 is led out can be increased both when the lid 40 is laid down and when it is erected.

  Note that the chamfered portion 47 is indispensable from the viewpoint that the lid body 40 is easily detached when it is overloaded in the opening direction, but the first meat portion 26 and the second meat portion 27 are not indispensable. .

  Although the insertion portion 42 of the free end 40a of the lid 40 is formed as a notch, the insertion is mainly for leading the cord portion 32 of the connection cord 30 rearward when the lid 40 is in the standing state. The part may be a hole. However, the handling of the connection cord 30 is easier in the cutout portion than in the hole. Moreover, you may provide such an insertion part in two or more places.
