Description

  The present invention relates to a photographing device such as a camera and other devices using a battery as a power source, and more particularly to a battery holder configured to be detachable from a device body while holding the battery.

  In a device or apparatus that employs a battery as a power source, the battery replacement operation becomes complicated as the number of batteries increases. For this reason, there has been proposed a battery holder in which a plurality of batteries are held in advance and the battery holder is attached to or detached from an apparatus or device. In particular, in digital cameras that shoot still images and moving images, the number of batteries tends to increase with an increase in power supply capacity. Therefore, a camera having a battery holder that is detachable from the camera has been proposed. For example, Patent Document 1 proposes a battery grip that is attached to a camera body, and a battery holder is detachably attached to the battery grip. As this type of battery holder, there are many battery holders that use a cylindrical R-type battery that is easily available not only in Japan but also overseas, especially an R6 battery called an AA battery in Japan. A battery holder using an R-type battery has also been proposed, and six R-type batteries are held in a battery holder, and the battery holder is mounted on a battery grip that is attached to and detached from a camera.

The third and sixth battery lock portions 43 and 46 for locking the third and sixth two batteries B3 and B6 are arranged in the length direction. Further, in the second battery lock groove 52, second and fifth battery lock portions 42 for locking the second and fifth batteries B2 and B5 held in the second holding frame 312 respectively. 45 and a fourth battery lock portion 44 for locking the fourth battery B4 held by the fourth holding frame 314 is disposed in the length direction. The first to sixth battery lock portions 41 to 46 are arranged when the batteries B1 and B4 are inserted into the holding frames 311 and 314 as representatively shown by the battery lock portions 41 and 44 in FIG. In addition, in the case of the first battery lock portion 41, the position within the battery outer diameter of the battery B <b> 1 and the position outside the battery center inside the battery outer diameter of the batteries B <b> 1, B <b> 4 is larger than the battery center position. 3 is a position displaced to the upper side of FIG. 3, and in the case of the fourth battery lock portion 44, a position displaced to the lower side of FIG. 3 from the battery center position within the range of the battery outer diameter of the battery B4. It is arranged. The same applies to other battery lock portions.

  The said lock part 4 (41-46) is the same structure, and the partial exploded perspective view of the 1st battery lock part 41 is shown in FIG. A pair of guide ribs 411 are formed in the first battery lock groove 51 at a position corresponding to the first battery lock portion 41 in the groove width direction at a required interval, and a corresponding first holding frame is provided between the guide ribs 411. A cutout 412 extending from the upper edge to the bottom surface is formed in the side edge portion 341 of 311. Between the guide ribs 411, a battery lock piece 413 having a generally convex shape in plan view is housed, and a lock front end 414 formed in a narrow width is loosely fitted into the notch 412. As can be seen from FIGS. 3 and 7, the lock tip 414 has an outer taper surface 414a and an inner taper surface 414b that are inclined at substantially the same angle at the tip, but the inner taper surface 414b is the outer taper. It is formed longer than the surface 414a. Therefore, the position where both the tapered surfaces 414a and 414b intersect, or the virtual intersection position thereof, is biased to the outside of the middle in the thickness direction of the tip 414. Further, as described above, the battery lock portion 41 is offset outward from the center of the battery B1, but is particularly offset outward from the center of the battery B1 held by the lock tip 414.

  A protrusion 415 is integrally formed on the rear end surface of the battery lock piece 413 that is recessed, and one end of a coil spring 416 having an axial core directed in the width direction of the battery lock groove 51 is fitted into the protrusion 415. Are combined. The other end of the coil spring is fitted between a pair of wedge-shaped sandwiching protrusions 417 provided on the side edge 343 of the third holding frame 313, and is supported while being sandwiched by these sandwiching protrusions 417. Yes. A lock cover 418 formed of an elongated plate is placed on the battery lock groove 51 so as to cover the battery lock piece 413 and the coil spring 416, and is screwed into a screw hole 411a provided in a part of the guide rib 411. The battery lock groove 51 is fixed by a screw 419. Accordingly, the battery lock piece 413 is sandwiched between the battery lock groove 51 and the lock cover 418 in the vertical direction, and the groove of the battery lock groove 51 by the spring force of the coil spring 416 with the pair of guide ribs 411 sandwiched in the left-right direction. The lock tip 414 is moved in the width direction so that the lock front end 414 can advance and retreat with respect to the first holding frame 311.

  As shown in FIG. 5, the third and sixth battery lock portions 43 and 46 are notched in the side edge portion 343 of the third holding frame 313, and accordingly the first battery lock portion 41 is formed. And a symmetrical configuration. The lock cover 418 is formed to be elongated so as to cover the first, third, and sixth battery lock portions 41, 43, and 46 collectively. Since the configurations of the second, fourth, and fifth battery lock portions 42, 44, and 45 shown in FIG. 6 are the same, the same reference numerals are given and description thereof is omitted. Here, the position of each battery lock part 41-46, especially the position of the length direction with respect to each holding frame 311-314 is from the intermediate position of the length direction of battery B1-B6 hold | maintained at each holding frame 311-314. Is also arranged at a position biased to one side, here a position biased toward the tip end side of the holder portion 3. Further, as described above, the virtual intersection position where the outer tapered surface 414a and the inner tapered surface 414b intersect with each other is biased outward from the middle in the thickness direction of the battery lock piece 413. The effect of this configuration of the battery lock piece 413 will be described later.

The operation of these battery lock portions 41 to 46 will be described with reference to FIG. FIG. 9 is a diagram illustrating the operation of the first battery lock unit 41. As shown in FIG. 9A, when the battery B1 is not held in the first holding frame 311 (hereinafter simply referred to as the holding frame), the lock tip of the battery lock piece 413 is driven by the spring force of the coil spring 416. The portion 414 is in the state of having advanced into the holding frame 311 through the notch 412. When the battery B1 is held by the holding frame 311 and the battery B1 is inserted into the holding frame 311 from the opening side in this state, the outer taper of the lock tip 414 is formed as shown in FIG. 9B. The outer peripheral surface of the battery B1 comes into contact with the surface 414a, and the taper action generates a force in the direction of retracting the lock tip 414 from the holding frame 311. The lock tip 414 is inside the holding frame 311 while reducing the coil spring 416. Accordingly, the battery B1 can be inserted into the holding frame 311. When the battery B1 is inserted into the holding frame 311, the battery lock piece 413 is pushed out by the spring force of the coil spring 416 as shown in FIG. 9C, and the lock tip 414 advances into the holding frame 311 through the notch 412. The inner tapered surface 414b comes into contact with the circumferential surface of the battery B1. Due to the taper action at this time, the lock tip 414 abuts the outer peripheral surface of the battery B1 toward the bottom and side surfaces of the holding frame 311 to prevent the battery B1 from falling off the holding frame 311 and to lock the battery. . In particular, the battery lock piece 413 is located outside the battery center of the battery B1, and the virtual crossing position where the inner tapered surface 414b and the outer tapered surface 414a intersect is the thickness direction of the lock tip 414 of the battery lock piece 413. Since it is biased to the outside of the middle, the position where the lock tip 414 contacts the outer peripheral surface of the battery B1 becomes the position on the outer diameter side of the battery B1, and the locking effect of the battery B1, that is, the drop prevention effect is enhanced. It becomes.

  When removing the battery B1 from the holding frame 311, the end of the battery B1 in the length direction is hooked with a fingertip or the like and pulled up. The battery B1 is pulled up in an oblique posture. At this time, the outer peripheral surface of the battery B1 comes into contact with the inner taper surface 414b of the lock front end portion 414. A force is generated, and the coil spring 416 is contracted by this force, the lock tip 414 is retracted from the holding frame 311, and the battery B 1 can be taken out from the holding frame 311. The operation of the second to sixth battery lock portions 42 to 46 is exactly the same.

  As described above, in the first battery lock portion 41, when the battery B1 is inserted into the holding frame 311 and when the battery B1 is taken out from the holding frame 311, the spring force of the coil spring 416 is resisted. Then, the battery lock piece 413 is retracted. Further, when the battery B <b> 1 is held on the holding frame 311, the battery is held by the battery lock piece 413 by the spring force of the coil spring 416. Therefore, the material constituting the holding frame 311 can be designed independently of the battery lock piece 413, the coil spring 416, and the lock cover 418 of the battery lock portion 41. Therefore, when the material of the holding frame 311 is designed, even when the rigidity and strength of the holding frame 311 are increased to ensure stable holding of the battery B1, the spring of the coil spring 416 is independent of this. By designing the force to a suitable spring force, it is possible to easily perform an operation when replacing the battery B1, and it is possible to stably hold the battery B1 in the holding frame 311. The same applies to the second to sixth battery lock portions 42 to 46. In this embodiment, the communication window 32 is provided at the boundary between the holding frames 311 to 314 that hold two batteries B2, B5, B3, and B6 arranged in series with one battery B1 and B4, respectively. Even if the holders 3 are reduced in size by reducing the dimensions in the arrangement direction of the arranged batteries, the holding frame 311 is configured so that the outer peripheral surfaces of the adjacent batteries B1 to B6 are in contact with each other. By designing the rigidity and strength of ˜314 sufficiently large, the battery can be stably held in the holding frame regardless of the presence of the communication window 32.

  In the embodiment, the six battery lock portions disposed for each of the six batteries B1 to B6 include three batteries in the first battery lock groove 51 and the second battery lock groove 52, respectively. The lock portions 41, 43, 46 and 42, 44, 45 can be configured together, and the battery lock pieces 413 and the coil springs 416 constituting the battery lock portions 41 to 46 have the same configuration. The lock cover 418 covering ˜46 is common and has the same configuration in the two battery lock grooves 51 and 52, which is advantageous in reducing the number of parts. Further, here, the holding frames 311 to 314 need only be integrally formed with side edge portions 341, 342a, 342b, and 343 for forming the lock grooves 51 and 52, and the battery lock portions 41 to 46 are configured. Since there is no need to integrally form the other part of the battery, the molding die can be simplified compared to the configuration in which the battery lock piece is integrally molded with the holding frame as in Patent Document 1, and the holder part is designed. As well as molding, it is possible to perform molding easily.

  Here, as described above, each of the battery lock portions 41 to 46 is disposed at a position biased to one side with respect to the batteries B1 to B6 to be locked, rather than an intermediate position in the battery length direction. 10, when the battery B1 is to be held in the holding frame 311 or to be taken out from the holding frame 311, the battery lock piece 413 of the battery lock unit 41 is Since the battery B1 has advanced into the holding frame 311, the battery B1 is supported by the battery lock piece 413 at a position biased to one side, and is held in a state where one end of the battery B1 is lifted and inclined. The posture is placed on the frame 311. Thereby, it becomes easy to perform an operation when holding or taking out the battery B1. Assuming that the battery lock piece 413 is provided at an intermediate position in the length direction of the battery B1, when the battery B1 is placed on the holding frame 311, the tilt direction of the battery is not determined, and it becomes difficult to handle the battery B1. . The same applies to the other battery lock portions 42 to 46.

  In addition, in this embodiment, although it is a structural example of the battery holder holding 6 batteries, it cannot be overemphasized that the number of batteries is not restricted to this number. In addition, the battery arrangement may be configured in a different arrangement such as 2 × 3 rows according to the external dimensions required for the battery holder.

  The battery holder of the present invention is not limited to the battery holder loaded in the battery grip described in the embodiment, and can be similarly applied to a battery holder loaded directly in the camera body. The battery holder of the present invention is not limited to the battery holder of a camera as long as it is a device that uses a battery as a power source. Moreover, as long as the battery is an R-type battery, another battery such as a single-type battery or a single-type battery may be used.

  The present invention can be employed as a battery holder for various devices that use a battery as a power source, particularly for a battery holder that is miniaturized.
