Description

  The present invention relates to an apparatus for carrying a battery of an automobile.

  Conventionally, when replacing the battery of an automobile, the wiring connected to the battery is removed in the engine room, and then the battery is pulled out and transported by hand. However, in addition to having a considerable weight, the battery compartment can become hot, and the gap around the battery is usually narrow, so careful transportation to prevent burns and injuries is necessary. Need attention.

  Therefore, for example, as shown in FIG. 6A, there is known an instrument for holding and transporting a battery. The battery carrying device 100 includes two sandwiching portions 110 and 111 that face each other, a spring 120 that biases them toward each other, and a grip 130. Rubber pads 110a and 111a are provided at the ends of the sandwiching portions 110 and 111, respectively.

  In order to carry the battery B using the battery carrying device 100, as shown in FIG. 6C, the grip 130 is gripped, a finger is placed on the coil portion 121 provided on the spring 120, and the spring 120 is biased. By pulling the coil part 121 in the grip 130 direction against this, the gap between the holding parts 110 and 111 is opened in the directions of the arrows P1 and P2, and the battery B is arranged between the holding parts 110 and 111 in this state. Release your finger. Then, since the rubber pads 110a and 111a hold the battery B by the bias of the spring 120, the battery B can be lifted by grasping the grip 130.

  Depending on the application, two sharp protrusions 110b and 111b can be provided on the holding portions 110 and 111, respectively, as shown in FIG. 6 (b). By using the protrusions 110b and 111b for the battery to be discarded, the battery can be securely held, and the new battery can be carried without being damaged by using the rubber pads 110a and 111a.

  However, the battery carrying device 100 may lose balance if the center of gravity of the battery B is not accurately pinched, and it may be difficult to carry and may drop the battery. Further, since the holding portions 110 and 111 are usually arranged and held in the width direction of the battery B, the battery is long in the side surface direction of the user and easily touches the foot during walking.

  In view of the above-described problems, an object of the present invention is to provide a battery carrying device that can easily maintain a balance and can easily carry a battery.

  In order to achieve the above object, a battery carrying device of the present invention includes a handle, and first and second arms that are supported between the handle and a positive terminal and a negative terminal of the battery and support the battery. And the first and second arms have first and second holes for fitting positive and negative terminals at their tips.

It is desirable that the battery carrying device includes an elastic member that is elastically mounted between the handle and the battery and biases the battery with the terminal fitted in the hole.

It is desirable to have third and fourth holes having different diameters from the two holes.
Each of the holes desirably has a friction portion at a portion in contact with the terminal.
Each of the arm portions may include an upper arm portion supported by a handle and a lower arm portion including a hole and detachably held by the upper arm portion. Alternatively, the handle may be pivotally supported via a screw so as to be swingable.

According to the present invention, the positive and negative terminals are fitted into the first and second holes by lifting the handle, and the battery can be supported by the first and second arms. By urging the elastic member to the battery, it is possible to generate a frictional force necessary for fitting the positive and negative terminals into the first and second holes. By providing the third and fourth holes, it is possible to deal with two types of standard batteries. By providing the friction part in the part of the hole that contacts the terminal, the battery can be held more reliably.
The arm part is composed of an upper arm part that is supported by the handle and a lower arm part that includes a hole and can be attached to and detached from the upper arm part, so that the lower arm part can be exchanged according to the terminal size of the + and-poles. In addition, it is supported by a screw so that it can be swung, so that the space between the holes in the lower arm can be adjusted according to the space between the + and-poles. can do.

That is, by providing the third hole 51 and the fourth hole 61 in addition to the first hole 31 and the second hole 41, it is possible to deal with batteries of two different standards.

  The center line 31a of the first hole 31 and the center line 41a of the second hole 41 are parallel to the center line 21c of the interposing member 21, and the same applies to the third hole 51 and the fourth hole 61. is there. That is, the first to fourth holes 31, 41, 51 and 61 are formed in directions parallel to the center line 21 c of the interposing member 21. Further, the first arm portion 4 and the fourth arm portion 6 and the second arm portion 4 and the third arm portion 5 are respectively formed in a “<” shape as described above, and the bent portions 36 and 45 are formed. Is connected to the horizontal member 24 through the horizontal member 24 and is positioned almost symmetrically across the horizontal member 24. That is, the center line 21c of the interposing member 21 exists in parallel away from the plane passing through the center lines 31a and 41a of the first and second holes.

  A method for carrying a battery using such a battery carrying device 1 will be described. FIG. 2 is a diagram showing a procedure for lifting the battery of the first standard by using the first and second arms 3 and 4 of the battery carrying device 1, and (a) is a diagram for installing the battery carrying device 1 on the battery. Before, (b) shows the installed state, (c) shows the state where the battery is pulled up, and (d) shows the state where it is removed from the battery.

  First, as shown by arrows A1 and A2 in FIG. 2A, the battery carrying device 1 is arranged so that the first hole 31 and the second hole 41 fit into the + terminal B1 and the -terminal B2 of the battery B. To do.

  Next, as shown in FIG. 2 (b), the battery carrying device 1 is pressed against the battery B by pushing down the handle 2. Then, the spring portion 7 comes into contact with the upper surface of the battery B and contracts. Specifically, when the battery carrying device 1 is pressed against the battery B, the lower end of the sliding member 74 comes into contact with the upper surface of the battery B, and when the battery carrying device 1 is pressed further strongly, the sliding member 74 is moved to the spring 73. It slides in the direction of the handle 2 along the spring guide member 71 against the bias. Then, the positive terminal B1 and the negative terminal B2 of the battery B enter the first and second holes 31 and 41, respectively.

  In this state, as shown in FIG. 3A, the force to push down the handle 2 is weakened, and at the same time, the battery carrying device 1 is tilted to the + terminal B1 and −terminal B2 side, that is, the left side in the drawing. Then, the center line 21c of the interposing member 21 is tilted to the left in the drawing, and accordingly, the center lines 31a and 41a of the first and second holes are tilted with respect to the + terminal B1 and the -terminal B2 of the battery B. Therefore, as shown in FIG. 3B in which the first hole 31 and the + terminal B1 are shown in an enlarged cross-section, of the wall forming the first hole 31, the lower part 31b outside the battery and the upper part inside the battery 31c comes into contact with the positive terminal B1, and friction occurs.

  Here, the spring portion 7 tries to recover due to its elasticity. That is, the lower end of the sliding member 74 is pressed against the upper surface of the battery B in an attempt to extend in the length direction, and the horizontal member 24 is pushed upward by the reaction. Then, the principle of the lever which uses the above-described lower part 31b of the battery and the upper part 31c of the battery as a fulcrum and a point of action works, and the press-contact of the part further increases, and the frictional force increases. The above operation is the same for the second hole 41 and the negative terminal B2.

  Therefore, as shown in FIG. 2C, the battery B can be lifted by holding the handle 2 and lifting the battery carrying device 1 in this state. At this time, the action of the above-described insulator is further strengthened by the dead weight of the battery B, and the first and second holes 31 and 41 strongly hold the positive terminal B1 and the negative terminal B2 of the battery B.

  After the battery B is lifted and transported as described above, the battery transport device 1 is removed from the battery by placing the battery B in an appropriate place and as shown by a one-dot chain line in FIG. By making the center line 21c of the interposing member 21 perpendicular to the upper surface of the battery B, the pressure contact relationship between the first and second holes 31 and 41 and the + terminal B1 and the −terminal B2 is released. Therefore, it can be easily removed from the battery B by lifting the battery carrying device 1 as shown in FIG.

  As described above, the method for transporting the first standard battery B using the battery transport device 1 of the first embodiment has been described. However, when transporting the second standard battery, the third and second Four arms 5 and 6 are used. That is, as described above, the third and fourth holes 51 and 61 are molded so that their diameters and intervals correspond to the battery of the second standard. The battery can be transported. The method of use is the same as described above except that the third and fourth holes 51 and 61 are fitted to the positive terminal and negative terminal of the battery instead of the first and second holes 31 and 41, respectively. To do. As described above, according to the battery transport device 1, it is possible to transport two types of standard batteries easily and safely without replacing parts or the like.

  In addition, even if it is the battery transport instrument (illustration omitted) which concerns on 2nd embodiment provided with the structure similar to the battery transport instrument 1 except not providing the spring part 7, it is the same by utilizing the dead weight of a battery. The battery carrying device 1 having the spring portion 7 can be lifted by the first and second holes 31, 41, the positive terminal B1 and the negative terminal B2 of the battery B in the stage before the lifting as described above. This is advantageous in that strong friction occurs between the two.

  FIGS. 4A and 4B show the shape of the hole H of the battery carrying device according to the third embodiment, which is different from the battery carrying device 1 only in the shape of the first to fourth holes. ) Is a plan view, and (b) is a bottom view. In such a battery carrying device, the friction which is several slits for increasing the frictional force in the lower part outside the battery and the upper part inside the battery in the walls forming the first to fourth holes H. Part H1 and H2 are provided. The battery carrying device according to the third embodiment is the same as the battery carrying device according to the first embodiment in other respects. If the battery carrying device according to the third embodiment is used, stronger friction is generated, and safety is improved.

When the pin 83 is pushed into the lower arm 83 against the bias of the elastic member, the lower arm 83 is slid into the upper arm 82, and the pin 83 overlaps the hole 82a of the upper arm 82. The pin 83 protrudes from the lower arm portion 83 by the urging of the elastic member therein, and fits into the hole 82a. As a result, the lower arm 83 is joined to the upper arm 82.
On the other hand, in order to remove the lower arm portion 83 from the upper arm portion 82, an operation reverse to the above-described insertion is performed. That is, the pin 83 is pushed against the urging force of the elastic member, and the lower arm portion 83 is pulled out from the upper arm portion 82.

  With the above operation, the lower arm 83 can be detached from the upper arm 82. Therefore, it can be replaced with a lower arm portion having a suitable hole according to the battery standard.

  The second arm portion 9 includes an upper arm portion 92 and a lower arm portion 93, and the upper arm portion 92 has a bolt hole 95a and a small hole 92a. The lower arm portion 93 has a second hole 91 and a pin 93. Since the upper arm portion 92 and the lower arm portion 93 of the second arm portion 9 have the same configuration as the upper arm portion 82 and the lower arm portion 83 of the first arm portion 8, description thereof is omitted.

  The first and second arm portions 8 and 9 are connected to the horizontal member 24 by screwing the butterfly screws 19a and 19b into bolt holes 85a and 95a provided in the base portions 85 and 95, respectively. And 19b are provided with flanges 19c and 19d, which can be adjusted by hand rotation, so that the thumb screws 19a and 19b are rotated in the loosening direction, and the first and second arm portions 8 and 9 are The first and second holes 81 and 82 are arranged so as to correspond to the positive terminal and the negative terminal of the battery, and can be adjusted by rotating in the tightening direction.
