Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a lid opening/closing mechanism and an electronic device storage case. 
         [0002]    Priority is claimed on Japanese Patent Application No. 2013-223533, filed on Oct. 28, 2013, the contents of which are incorporated herein by reference. 
       BACKGROUND ART 
       [0003]    A storage case of an electronic device, which is installed in the outdoors or under an environment of high humidity, has a structure which can seal an aperture plane of a case body with a lid so that the electronic device stored in the inside may not be influenced by moisture. 
         [0004]    Conventionally, for example, a case opening/closing mechanism shown in the patent document 1 is mentioned as the storage case of the electronic device which can seal the inside. Invention described in the patent document 1 has a structure for moving the lid in parallel with a horizontal direction with respect to the case body and rotating the lid around a hinge axis. By the structure, the lid can be in close contact with the case body, and outside air and moisture can be prevented from entering into the case body. 
         [0005]    On the other hand, in a case that a connector for connecting to the electronic device stored in the case body of the storage case, a display panel of the electronic device, an operation panel, and so on are mounted on an external surface of the lid, it is necessary that a distribution cable is disposed between the case body and the lid so that the lid can be opened and closed. As the storage case of the electronic device where the distribution cable is disposed between the case body and the lid, for example, an attachment device of the electronic device shown in the patent documents 2 is mentioned. According to the patent document 2, a main body and an attachment base can be rotated by a hinge member, and a connection lead connects between the electronic device in the main body and a wiring connection part of the attachment base. The connection lead is hanged down with excess length between the electronic device and the attachment base so that the electronic device and the attachment base can be rotated.

       SUMMARY OF INVENTION 
     Technical Problem 
       [0007]    However, in the case opening/closing mechanism disclosed in the above-described patent document 1, it is not supposed that a distribution cable is disposed between the lid and the case body. Therefore, in the patent document 1, a distribution cable for allowing the parallel movement and the rotation of the lid with respect to the case body is not disclosed at all. 
         [0008]    On the other hand, in the attachment device of the electronic device disclosed in the patent document 2, the connection lead is disposed between the main body and the attachment base. However, in the patent document 2, the main body just rotates with respect to the attachment base, and a structure for moving the main body in parallel with the attachment base is not disclosed at all. 
         [0009]    Moreover, since the connection lead described in the patent document 2 is hanged down between the electronic device and the attachment base, there is a problem of workability, for example, the connection lead interferes work when the electronic device is operated. Since a space for storing the connection lead is necessary to be large so that the connection lead can be hanged down between the main body and the attachment base, it is difficult to downsize the attachment device. In addition, it is necessary to provide a sleeve and a cableveyor (registered trademark) at a part where the connection lead hanged down with excess length, and there is also a problem of increasing manufacturing cost due to increase of components. 
       Solution to Problem 
       [0010]    In order to solve the above problems, a lid opening/closing mechanism, which attaches a lid to an opening of a case body to be openable and closable, and holds a distribution cable electrically connecting the case body and the lid, includes a first member which is attachable to an attachment surface of the case body and slidable along the attachment surface, and a second member of which one side is rotatable and attachable to the first member, and of which another side is fixed to the lid, wherein the distribution cable is curved and held along the first member and the second member. 
         [0011]    Moreover, in the lid opening/closing mechanism of the present invention, the first member and the second member are an integrated plate member, and a thinned part of which thickness is reduced is formed in a boundary between the first member and the second member. 
         [0012]    Moreover, the lid opening/closing mechanism of the present invention further includes a cable holding member which faces the first member and the second member and holds the distribution cable, and a space for storing the distribution cable is formed between the cable holding member, the first member, and the second member. 
         [0013]    Moreover, in the lid opening/closing mechanism of the present invention, the cable holding member includes a first part fixed to the first member and a second part rotatably engaged with the first part. 
         [0014]    Moreover, in the lid opening/closing mechanism of the present invention, the first member and the first part included in the cable holding member is an integrated member. 
         [0015]    Moreover, the lid opening/closing mechanism of the present invention further includes a pressing member which is attached to make the second part included in the cable holding member slidably follow the second member. 
         [0016]    Moreover, in the lid opening/closing mechanism of the present invention, the cable holding member is a guide member which guides the distribution cable along a curved part of the distribution cable. 
         [0017]    Moreover, in the lid opening/closing mechanism of the present invention, the distribution cable is held to be an approximately S-shape along the first member and the second member. 
         [0018]    Moreover, the lid opening/closing mechanism of the present invention further includes a stopper member which is disposed in the attachment surface of the case body and the first member, the stopper member regulating a range of slide of the first member. 
         [0019]    Moreover, in the lid opening/closing mechanism of the present invention, all of the first member, the second member, and the cable holding member are integrally molded by using resin. 
         [0020]    Moreover, an electronic device storage case includes a case body which has an opening, a lid which is attached to the opening to be openable and closable, a distribution cable which electrically connects the case body and the lid, a first member which is attachable to an attachment surface of the case body and slidable along the attachment surface, and a second member of which one side is rotatable and attachable to the first member, and of which another side is fixed to the lid, wherein the distribution cable is curved and held along the first member and the second member. 
       Advantageous Effects of Invention 
       [0021]    In the lid opening/closing mechanism and the electronic device storage case of the present invention, the first member is attachable to an attachment surface of the case body and slidable along the attachment surface, the second member of which one side is rotatable and attachable to the first member, and of which another side is fixed to the lid, and the distribution cable is curved and held along the first member and the second member. Thereby, the lid opening/closing mechanism can be positioned in a small space while allowing the lid to slide and rotate, and workability can be improved when the lid is opened and the electronic device is operated.

     DESCRIPTION OF EMBODIMENTS 
       [0039]    An aspect of some embodiments of the present invention is to provide a lid opening/closing mechanism and an electronic device storage case, which include a distribution cable between a case body and a lid, and can allow movement of the lid in a storage case in which the lid is slidable and rotatable with respect to the case body, can be positioned in a small space, and can improve workability when the lid is opened and the electronic device is operated. 
         [0040]    Embodiments of a lid opening/closing mechanism and an electronic device storage case will be described below, with reference to drawings. The present embodiment is described specifically so that the meaning of the invention can be understood better, and the present invention is not limited unless otherwise specified. Moreover, in order to understand an aspect of the present invention easily, there is a case that drawings used for the description below illustrate an enlarged main part for convenience, and a dimensional ratio of each component is not necessarily the same as an actual ratio.

         [0042]    The case  11  includes a case body  12  and a lid  13 . For example, the case body  12  is a cuboid-shaped hollow box, and an opening  12   a  is formed at one side of the case body  12 . 
         [0043]    The lid  13  has a structure which can seal the opening  12   a  of the case body  12 . The lid  13  is connected to the case body  12  by a lid opening/closing mechanism  20 . A waterproof seal component  19 , such as packing, may be disposed between the opening  12   a  of the case body  12  and the lid  13 . 
         [0044]    An attachment slot  14  is formed in an upper side and a lower side of the attachment surface  12   b  of the case body  12  to which the lid opening/closing mechanism  20  is attached. The attachment slot  14  makes it possible that the lid opening/closing mechanism  20  engages and slides along the attachment surface  12   b . Slide slots  15  are formed in the attachment surface  12   b  of the case body  12 . The slide slots  15  are stopper components for regulating slide range of the lid opening/closing mechanism  20 . 
         [0045]    A pressing member  17  is formed on an inner surface  13   a  of the lid  13 . The pressing member  17  allows a second part  41   b  of a cable holding member  41  described later to rotate in order to follow a second member  31 . The pressing member  17  makes it possible that the second part  41   b  slides in order to follow the second member  31 . Thereby, the second part  41   b  rotates following the rotation of the second member  31 . 
         [0046]    The lid opening/closing mechanism  20  of the present invention includes a first member  21 , a second member  31 , and a cable holding member  41 . For example, the first member  21 , the second member  31 , and the cable holding member  41  are molded as an integrated resin member. If whole of the lid opening/closing mechanism  20  is integrally formed by injection molding, the lid opening/closing mechanism  20  can be easily manufactured at low cost. 
         [0047]    The first member  21  is a plate-shaped member. The second member  31  is connected to one side  21   a  of the first member  21 . The cable holding member  41  is connected to another side  21   b  of the first member  21 . Ridges  22  are formed on the upper end and the lower end of the first member  21  respectively. The ridges  22  respectively fit into the attachment slots  14  formed in the attachment surface  12   b  of the case body  12 . Slide projections  23  are formed on one side  21   c  where the first member  21  faces to the attachment surface  12   b  of the case body  12 . The slide projections  23  respectively fit into the slide slots  15  formed in the attachment surface  12   b  of the case body  12 . 
         [0048]    The attachment slots  14  respectively slide and fit to the ridge  22  so that the lid opening/closing mechanism  20  can slide along the attachment surface  12   b  of the case body  12 . The slide range of the lid opening/closing mechanism  20  is regulated by the slide slots  15  and a stopper member within the length range of the slide slots  15 . The stopper member includes the slide projections  23  respectively fitting into the slide slots  15 . Thereby, the lid opening/closing mechanism  20  can be prevented from dropping from the case body  12 . 
         [0049]    Moreover, engaging projections  24  are formed on another side  21   d  of the first member  21 . The engaging projections  24  respectively fit into engaging holes  45  formed in a cable holding member  41  described later. The ridges  22 , the slide projections  23 , the engaging projections  24  may be formed integrally as a part of the first member  21 . 
         [0050]    The second member  31  is a plate member formed integrally with the first member  21 . The side  31   a  of the second member  31  is rotatably mounted with respect to the side  21   a  of the first member  21 . A bottomed groove which extends along the vertical direction C of the plate member is formed in the boundary of the second member  31  and the first member  21 . The bottom of the groove is a thinned part  52  which is thinner than other parts of the second member  31  and the first member  21 . 
         [0051]    The thinned part  52  makes it possible that the second member  31  is rotated around the vertical direction C as a rotational axis with respect to the first member  21 . As the groove formed in the boundary (rotating part) between the second member  31  and the first member  21 , for example, a V-shaped groove and a U-shaped groove are given. 
         [0052]    Attachments  32  are formed integrally with another side  31   b  of the second member  31 . The lid  13  is fixed to the attachments  32 . For example, the second member  31  is attached vertically to the inner surface  13   a  of the lid  13 . A fixing method of the second member  31  and the lid  13  is not limited to a specific method. For example, a screw hole may be formed in the attachment  32  of the second member  31 , and the attachment  32  and the lid  13  are fixed by a screw through the screw hole. The attachment  32  has a shape which can be folded at right angle with respect to the surface of the second member  31  by a thinned part  39  in which a groove is formed between the attachment  32  and the second member  31 . 
         [0053]    A guide member  33 , which is along a curved part of the distribution cable described later, is formed integrally on the upper side of the second member  31 . The guide member  33  prevents that the distribution cable is folded in an unexpected direction and deviates greatly from the lid opening/closing mechanism  20 . 
         [0054]    The cable holding member  41  is a plate member formed integrally with the first member  21 , and has a first part  41   a  and a second part  41   b . The cable holding member  41  is attached to the other side  21   b  of the first member  21  at an upper end and a lower end of the end side  41   c  of the cable holding member  41 . For example, a connection part  38  between the cable holding member  41  and the first member  21  is thinner and narrower than other parts of the cable holding member  41 . Thereby, the cable holding member  41  can be rotated (folded) from a position parallel to the first member  21  in a plane ( FIG. 2 ), to a position facing the other side  21   d  of the first member  21  ( FIG. 3 ). 
         [0055]    In addition, in the present embodiment, an example of the cable holding member  41  formed integrally with the first member  21  through the connection section  38  is described. However, the cable holding member  41  may be molded separately from the first member  21 , and attached so that the first member  21  faces the first part  41   a  and the second part  41   b.    
         [0056]    At a time of forming (manufacturing), the lid opening/closing mechanism  20  is formed integrally in a state that the cable holding member  41  is parallel to the first member  21  in a plane. At a time of using the lid opening/closing mechanism  20 , as shown in  FIG. 5A , the cable holding member  41  is rotated with respect to the first member  21  so as to be folded. 
         [0057]    As shown in  FIG. 5B , the first part  41   a  of the cable holding member  41  faces the other side  21   d  of the first member  21 , and these are overlapped. Thereby, the engaging projections  24  of the first member  21  respectively fit into the engaging holes  45  formed in the first part  41   a . An end part of the engaging projection  24  is slightly larger than the diameter of the opening of the engaging hole  45 . The end part of the engaging projection  24  is made of resin, and the engaging projection  24  fits into the engaging hole  45  and it is fixed by elasticity of the resin. 
         [0058]    In this way, the engaging projection  24  fits into the engaging hole  45  so that the first part  41   a  of the cable holding member  41  is fixed to the first member  21 . Moreover, the engaging projection  24  fits into the engaging hole  45  so that a cable storing space S which is a wiring duct storing the distribution cable described later is formed between the cable holding member  41  and the first member  21 . 
         [0059]    The second part  41   b  included in the cable holding member  41  is formed so as to be thinner than the first part  41   a . The second part  41   b  is rotatable around the boundary between the first part  41   a  and the second part  41   b  as a rotational axis with respect to the first part  41   a.    
         [0060]    The second part  41   b  included in the cable holding member  41  engages with the pressing member  17  of which end side was formed on the inner surface  13   a  of the lid  13 . Further, when the lid  13  is rotated, the second part  41   b  is rotated so as to follow the second member  31  in a state that the second part  41   b  is engaged with the pressing member  17 . That is, the pressing member  17  makes it possible that the second part  41   b  slidably follows to the second member. Thereby, the second part  41   b  also rotates so as to follow the rotation of the second member  31 . 
         [0061]      FIG. 6A  is a drawing illustrating an electronic device storage case equipped with the lid opening/closing mechanism.  FIG. 6B  is a perspective view illustrating a state of the distribution cable stored in the lid opening/closing mechanism. As shown in FIG.  6 A, the electronic device storage case  10  includes the case  11  and the lid opening/closing mechanism  20 . A circuit substrate  52  is disposed in the case body  12  of the case  11 . A circuit substrate  53  is disposed on the lid  13  of the case  11 . 
         [0062]    For example, the circuit substrate  52  disposed in the case body  12  is a main part of the electronic device. For example, the circuit substrate  53  disposed on the lid  13  may be a control circuit of an operation panel for operating the electronic device from outside of the case  11  and a display which displays a state of the electronic device to outside of the lid  13 . The connector  52   a  of the circuit substrate  52  disposed in the case body  12  and the connector  53   a  of the circuit substrate  53  disposed on the lid  13  are electrically connected to each other by the distribution cable  55 . 
         [0063]    As shown in  FIG. 6B , the distribution cable  55  has a plurality of thin wires arranged in parallel, and the distribution cable  55  is made of material which can be curved flexibly. The distribution cable  55  is curved between the connector  52   a  and the connector  53   a , and stored in the cable storing space S of the lid opening/closing mechanism  20 . For example, the distribution cable  55  is curved to an approximately S-shape along the first member  21  and the second member  31  of the lid opening/closing mechanism  20 , and the distribution cable  55  is arranged with an excess length. The distribution cable  55  is arranged so that the curved part is along the guide member  33 . Moreover, the distribution cable  55  is regulated by the cable holding member  41  so as not to be separated greatly from the first member  21  and the second member  31 . 
         [0064]    That is, the distribution cable  55  is arranged in the narrow cable storing space S formed between the first member  21  and the second member  31  and the cable holding member  41  facing them, so that the distribution cable  55  is curved by the guide member  33  to an approximately S-shape along the first member  21  and the second member  31 . If the lid  13  is opened or closed, the distance between the circuit substrate  52  and the circuit substrate  53  varies. Therefore, the length between the connector  52   a  and the connector  53   a  of the distribution cable  55  has a length for the variation of the distance and a length for maintaining the curved state of the distribution cable  55  after the lid  13  is opened, as the excess length. 
         [0065]    Behavior of the electronic device storage case equipped with the lid opening/closing mechanism of the above-described configuration will be described. In the following description, operation of the lid opening/closing mechanism will be described. As shown in  FIG. 6A  and  FIG. 6B , the lid of the electronic device storage case is closed. As shown in  FIG. 7A  and  FIG. 7B , the lid is slid and pulled out. As shown in  FIG. 8A  and  FIG. 8B , the lid is rotated and completely opened. 
         [0066]    As shown in  FIG. 6A , in a state where the lid  13  of the electronic device storage case  10  is closed (in a state where the lid  13  covers the opening  12   a  of the case body  12 ), the first member  21  and the second member  31  of the lid opening/closing mechanism  20  are arranged in a same plane. As shown in  FIG. 6B , the distribution cable  55  stored in the cable storing space S is greatly curved to an approximately S-shape along the first member  21  and the second member  31 . An outermost peripheral part in the curved part of the distribution cable  55  is held so that the S-shape can be kept by the guide member  33 . 
         [0067]    Operation of opening the lid  13  from a closed position of the lid  13  will be described. First, as shown in  FIG. 7A , a worker slides the lid  13  so as to pull it out from the case body  12 . With the slide of the lid  13 , the ridges  22  formed on the first member  21  are slid along the attachment slots  14  formed in the attachment surface  12   b  of the case body  12  ( FIG. 1  and  FIG. 2 ). The slide range of the lid  13  is regulated in a range where the slide projection  23  formed on the first member  21  can fit into the slide slot  15  formed in the attachment surface  12   b  of the case body  12  ( FIG. 1  and  FIG. 2 ). For this reason, the lid  13  is not dropped from the case body  12  when the lid  13  slides. 
         [0068]    If the worker slides the lid  13  so as to pull it out from the case body  12 , as shown in  FIG. 7B , the distance between the connector  52   a  and the connector  53   a  of the distribution cable  55  is increased. Accordingly, the excess length which is the curved part of the distribution cable  55  is stretched, and the curvature radius of the curved portion is changed. However, even if the lid  13  is pulled out completely from the case body  12 , the excess length of the distribution cable  55  is long enough to keep the curved state of the distribution cable  55 . For this reason, the distribution cable  55  is held along the first member  21  and the second member  31  in a state where the curved state is kept while changing the curvature radius. 
         [0069]    Next, as shown in  FIG. 8A , the worker rotates the lid  13  with respect to the case body  12  in order to expose the opening  12   a  of the case body  12 . Thus, if the worker does not slide the lid  13  and does not pull it from the case body  12 , the lid  13  cannot be rotated. Thereby, it can be prevented that the lid  13  rotates against intention of the worker. If the lid  13  is rotated, the second member  31  is folded around the thinned part  52  ( FIG. 2 ), which is a bottom of the groove formed in the boundary between the second member  31  and the first member  21  of the lid opening/closing mechanism  20 , as a rotational axis with respect to the first member  21 . 
         [0070]    At this time, as shown in  FIG. 9 , the second part  41   b  of the cable holding member  41  which faces the second member  31  is rotated so as to follow the rotation of the second member  31 . This is because the second part  41   b  is rotatable with respect to the first part  41   a  which is fixed to the first member  21 , and an end part of the second part  41   b  is engaged with the pressing member  17  formed on the inner surface  13   a  of the lid  13 . That is, since the pressing member  17  is engaged with the second part  41   b  of the cable holding member  41 , if the lid  13  is rotated, the second part  41   b  is also rotated while sliding against the pressing member  17 . 
         [0071]    By the mechanism, wherever the first member  21  and the second member  31  are positioned, the distribution cable  55  is covered with the cable holding member  41 . For example, in the opened position of the lid  13  shown in  FIG. 8A , the cable storing space S is curved in accordance with the curved shape of the second member  31  with respect to the first member  21 . 
         [0072]    If the lid  13  is rotated, as shown in  FIG. 8B , the distribution cable  55  is curved along the second member  31  which is curved from the first member  21  in the cable storing space S. Even if the distribution cable  55  is curved as such, the first member  21  and the second member  31  are covered with the cable holding member  41 . For this reason ( FIG. 9 ), the distribution cable  55  does not lose greatly touch with the lid opening/closing mechanism  20 , and the distribution cable  55  is kept to be along the first member  21  and the second member  31 . 
         [0073]    As described above, according to the lid opening/closing mechanism  20  and the electronic device storage case  10  in the present invention, when the worker slides and rotates the lid  13 , the distribution cable  55  can follow the movement of the lid opening/closing mechanism  20  while the distribution cable  55  is along the first member  21  and the second member  31  which are hinges. Thereby, the distribution cable  55  can be stored efficiently in the space of the lid opening/closing mechanism  20 , and the internal space of the electronic device storage case  10  can be used effectively. Since whole of the lid opening/closing mechanism  20  can be molded integrally by using resin, the lid opening/closing mechanism which has the distribution cable can be realized with a few components and at low cost. 
         [0074]    The above-described embodiment is an embodiment of the lid opening/closing mechanism of the present invention, and a configuration of each part is not limited unless otherwise described. 
         [0075]      FIG. 10  is a plan view illustrating another embodiment of a lid opening/closing mechanism of the present invention. In the lid opening/closing mechanism  70  shown in  FIG. 10 , a cylinder type cable in which a plurality of wires is stored as a distribution cable  71  is adopted. The distribution cable  71  is along the first member  21  and the second member  31  with an excess part curved to an approximately U-shaped. In this way, if the distribution cable is made of flexible material which can follow the slide and the curve of the lid opening/closing mechanism, a shape and a number of the distribution cable are not limited. Furthermore, if the distribution cable is curved along the first member and the second member, the curved shape of the excess length part of the distribution cable is not limited. 
         [0076]    In the above-described embodiment, although each of the first member and the second member is a plate member, for example, a frame member can be also used desirably to realize weight reduction and cost reduction. 
         [0077]    In the above-described embodiment, although the cable holding member is a plate member facing the first member and the second member, a linear support member, which prevents from greatly losing touch with the first member and the second member while the distribution cable is allowed to slide, may be disposed on a part of the first member and the second member. 
         [0078]    In the above-described embodiment, although the rotation part of the first member and the second member is realized by the thinned part formed by the groove, for example, a hinge including a rotation shaft and a bearing may be used. 
         [0079]    In the above-described embodiment, although the lid opening/closing mechanism is integrally molded by using resin material, for example, it may be made of metal material or combination of various types of materials.
