Description

[Detailed description of the invention] [Industrial application field] This invention relates to a storage battery in which a handle is rotatably attached to a lid that closes the opening of the battery case body. It is about the structure that makes it possible.

[Prior Art] A handle is sometimes attached to a storage battery for convenience when lifting or carrying the storage battery.

Such a handle is only necessary when the battery is to be carried by hand; in other situations, the presence of the handle may be a nuisance. Therefore,
It is desirable that the handle be in a form that does not take up much bulk when not in use.

Therefore, for example, when attaching a handle to the lid of a storage battery, if the handle is made rotatable, the handle can be raised only when needed and folded down when not in use. One possible solution is to attach the handle to the lid so that it can rotate. In this way, a storage battery equipped with a rotatable handle was developed, for example, in 1983-
It is described in Publication No. 78534.

In this prior art, support pins are provided on both sides of the lid of the battery case, and the support pins are passed through mounting holes installed at both ends of the handle, thereby making the handle rotatable around the support pin. When the handle is not in use, it can be folded down to lie along the lid. In particular, in the prior art described in this publication, a storage step is formed on the peripheral edge of the lid to receive the handle when not in use, and a retaining piece is provided on the support pin provided on the lid. It is formed.

On the other hand, there is also one in which a handle is rotatably attached to the side surface of the storage battery case body. In order to make such a handle rotatable, the handle is made of resin, and by utilizing the flexibility of such resin, the handle is made bendable via a hinge made of a thin part. The mounting structure is, for example, Jikko 56-
It is described in Publication No. 25496.

In this second prior art, the handles are provided on a pair of opposing outer surfaces of the battery case body, and when the handles are used, each of the pair of handles is placed upright along the side surface of the battery case. When the handles are not in use, they are turned downward and along the outer surface of the battery case body when the handles are not in use.

[Problems to be solved by the invention] However, the above-mentioned two conventional technologies have the following problems:
Each had the following problems.

First, in the first conventional technology, the work of attaching the handle to the support pin involves a relatively complicated process such as inserting each support pin into each attachment hole of the handle, so it is not possible to automate the process, for example. It cannot be done so easily.

Another problem with molding is that while forming a storage step, a support pin is provided that protrudes to the side, and such a support pin is provided with a retaining piece. is impossible to mold in one piece, for example by injection molding, or
Or rather difficult. Therefore, in practice, the support pin would be prepared separately from the lid and would be attached to the lid later. However, it is difficult to accurately attach the support pin to the specified position on the lid, and if the support pin is misaligned, the handle may not fit properly into the storage step when folded down. .

Furthermore, the rotatable structure, such as the combination of support pins and mounting holes, requires a relatively large amount of space, which can result in an oversized storage battery case. .

Next, in the second prior art, the handle is attached with the handle protruding from the outer surface of the battery case, so when multiple storage batteries are used side by side, the presence of such a handle makes it difficult for each storage battery to This creates wasted space in between. Furthermore, when storing batteries in storage means such as some types of boxes, there are problems such as the presence of handles that impede storage and the storage means having to have a larger volume. can be encountered.

Furthermore, as mentioned above, when multiple storage batteries are placed side by side or when the storage batteries are placed in a storage means, the handles should be placed upright and protruding from the top of the storage battery. It is preferable to place the battery case facing downward and aligned with the side of the battery case body in order to make the storage form more compact. However, if there is not much free space around the area where the battery is placed, you may have to remove your hand from the handle during the series of operations from lifting the battery via the handle to placing it in the designated location. If the handle is not turned downward in advance, it may not be possible to turn the handle downward after the storage battery is placed. Furthermore, even when lifting a storage battery that has already been placed in a predetermined location, if there is not enough space around the battery to turn the downward-facing handle upward, the handle cannot be used from the beginning. Other inconveniences may also occur. Thus, in the above-mentioned situation, even if the storage battery is provided with a handle, the handle cannot be used effectively.

Additionally, if the handles are attached to the opposing outer surfaces of the battery case, each handle must be held with both hands in order to lift the battery horizontally, and one person must hold each handle in order to lift the battery horizontally. You can only have one battery at a time.

Therefore, this invention is based on the above-mentioned first and second
The aim is to solve all of the problems contained in each of the conventional techniques in one go, and the work of attaching the handle is easy, and the structure for making such a handle attachment structure rotatable is extremely simple. An object of the present invention is to provide a storage battery with a handle that can be operated with one hand even when there is no space around the storage battery.

[Means for Solving the Problems] This invention is directed to a storage battery in which two handles are rotatably attached symmetrically to the top surface of a lid that closes the opening of the battery case body, and is directed to a storage battery that Various technical problems are solved as follows.

That is, the handle is made of resin, and is connected to the top surface of the lid via a bendable hinge made of a thin part at a position away from the side surface of the lid, and A recessed portion is formed to receive the handle when the handle is folded down along the top surface of the lid, and the upper edge of the grip portion of the handle is positioned so as to be exposed on the side surface of the lid when the handle is folded down. It is characterized by being

[Operations and Effects of the Invention] According to this invention, the handle is connected to the top surface of the lid via a hinge made of a thin portion that takes advantage of the flexibility of the resin that constitutes the handle. Therefore, such a handle is made pivotable by a hinge. Here, the structure adopted to make the handle rotatable is simply a hinge consisting of a thin wall, so almost no space is required to adopt this structure, and the storage battery case can be enlarged. Formation is prevented.

In addition, it is extremely easy to form a thin part that becomes a hinge in order to make the handle rotatable, and the work for attaching or forming such a handle is as follows:
Can be easily automated.

In addition, the handle is attached to the top of the lid, so
Even if there is not enough space around the storage battery, not only will it not interfere with the operation of the handles, but the two handles are connected to the lid at a distance from the sides of the lid, so that when the handles are upright, , since each grip part meets in the center, both handles can be easily gripped with one hand. Therefore, even if the storage space for the storage battery does not have enough space at all for the volume of the storage battery, you can lift the storage battery from there or place the storage battery there while holding the handle. This is extremely efficient and allows you to use both hands to handle two batteries at once.

Furthermore, according to the handle mounting structure of this invention, the handle is rotatable, so it can be erected only when the handle is needed, and when not in use, it can be folded down and placed into the recess. , it can be made into a less bulky state. In addition, as mentioned above, when the handle is folded down and received in the recess, it is difficult to put the handle in the upright position again because the upper edge of the grip part of the handle is exposed on the side of the lid. For example, this can be easily done by hooking a finger or the like.

Furthermore, the fact that the upper end edge of the grip part of the handle received in the recess is exposed to the side surface of the lid as described above means that the recess is open to the side surface of the lid. Therefore, any liquid such as rainwater or electrolyte that has entered the recess can be immediately drained out through this opening. Additionally, cleaning inside the recess is easy.

In addition, since the hinge is made up of thin parts, it tends to be easily damaged by external shocks.
In this invention, such a hinge is located away from the side of the lid, so it is less susceptible to external shocks.

[Example] Figures 1 to 3 show a first embodiment of this invention, in which Figure 1 is a plan view of the lid of the storage battery, and Figure 2 shows the line - in Figure 1. FIG. 3 is a cross-sectional view taken along the line - of FIG. 1. It should be noted that this invention only needs to be understood particularly in relation to the lid and the handle, so illustration of the structure on the battery case body side is omitted in these drawings and the drawings described below.

Referring to FIGS. 1 to 3, the lid 1 is for a lead-acid battery having, for example, six compartments, and therefore six liquid ports 2 are provided corresponding to each compartment. ing. Note that in the case of a sealed storage battery, such a liquid port is not provided. Also,
A partition wall 3 corresponding to a partition wall of a battery case body (not shown) is provided on the lower surface of the lid 1. Furthermore, a pair of pole rods 4 are provided passing through the lid 1.
The configuration described so far is the same as that of a conventional storage battery.

Two handles 5, 5 are attached symmetrically to the top surface of the lid 1 of such a storage battery with the row of liquid ports 2 in between. Each handle 5 has two vertical legs 6, 6, and a grip 7 connecting the upper ends of these vertical legs 6, 6, as shown in the overall shape in FIG.
and a mounting-side connecting portion 8 that connects the lower ends of the vertical legs 6, 6, and a hinge 9 is formed along the lower edge of the mounting-side connecting portion 8. In FIG. 1, the hinge 9 actually hardly appears as a line, but for illustrative purposes, the hinge 9 is shown as an area sandwiched between two parallel straight lines.
A mounting portion 10 is formed on the opposite side of the hinge 9 from the side on which the grip portion 7 is formed.

The handle 5 as described above can be made of any resin material, for example, resin such as polypropylene, polyethylene, polyamide, etc.
Molded in one piece.

For example, as clearly shown in FIG. 3, the hinge 9 is made of a thin portion and is bendable by utilizing the flexibility of the resin as described above.

The lid 1 can also be made of any resin material, such as polypropylene, acrylonitrile-butadiene-styrene resin, or the like. The handle 5 is joined to the lid 1 at the attachment portion 10 by heat welding, ultrasonic welding, adhesion, or the like.

In this embodiment, a handle 5 is provided on the top surface of the lid 1.
A recess 11 is formed along the top surface of the lid 1 to receive the lid 1 when it is folded down. This recess 11 also receives a portion of the attachment portion 10, and is selected in shape and size so that when the handle 5 is folded down, all portions of the handle 5 do not protrude from the top surface of the lid 1. For example, as best shown in FIG.
It is more profound in the area of acceptance. In this embodiment, as shown in FIG. 1, in order to receive the handle 5 that extends along each side of the rectangle as a whole, the recess 11 is also shaped to extend along each side of the rectangle. Ru. Therefore, the area 12 surrounded by the recess 11 is arranged on the same plane as the other part of the top surface of the lid 1. In addition, as can be seen in FIG. 1 for example, in the drawing, there is a recess 1 around the handle 5.
1 had a gap, but in order to prevent dust from entering, it is preferable that such a gap be as small as possible or not at all.

Further, the upper end edge of the grip portion 7 of each handle 5 is positioned so as to be exposed on the side surface of the lid 1. That is, the recess 11 is open at the side surface portion of the lid 1.

In such a storage battery, when lifting the storage battery using the two handles 5, hold the two handles 5, The storage battery can be lifted by aligning the grips 7, 7 of 5 with one hand and gripping with one hand. Note that these handles 5, 5 may be held with both hands.

Figures 4 to 6 show a second embodiment of this invention, in which Figure 4 is a plan view of the lid of the storage battery, and Figure 5 is a sectional view taken along the line - in Figure 4. 6 is a sectional view taken along the line - in FIG. 4. In this second embodiment, the first
Since it contains many elements in common with the example of
Corresponding parts are given the same reference numerals, and duplicate explanations will be omitted.

The main feature of the second embodiment shown in FIGS. 4 to 6 is that a bendable hinge 9a formed of a thin part is formed to extend integrally from the top surface of the lid 1. That is, in this embodiment, the handles 5a, 5a are integrally molded with the lid 1. Therefore, there is no part corresponding to the attachment part 10 provided on the handle 5 in the first embodiment described above.

Each handle 5a includes vertical leg portions 6a, 6a, a grip portion 7a, and a mounting side connecting portion 8a, as in the above-described embodiment.
However, a recess 11a for receiving such a handle 5a in a fallen state is formed to uniformly extend to the area surrounded by the handle 5a. This is to facilitate molding of the lid 1 that is integrally provided with the handle 5a. That is,
For example, if the recess 11 is formed to surround a protruding step like the region 12 in the first embodiment, the direction in which the mold is removed is limited to the direction perpendicular to the top surface of the lid 1. However, if the recess 11a is formed without a protruding step in the center as in the second embodiment, the mold removal direction will be parallel to the top surface of the lid 1. You can also choose. Therefore, it becomes easier to form the handle 5a integrally with the lid 1.

As in the second embodiment, a handle 5a is integrated with the lid 1.
When the hinge 9a is molded, the so-called "curve" after molding acts to make the handle 5a stand up from the top surface of the lid 1, for example, as shown in the solid line on the right side of FIG. 6. I might. However, in this case, the handle 5a may not be able to settle into the recess 11a due to the "curvature" of the handle 9a. Therefore, in this embodiment, the grip portion 7a of the handle 5a has a
An engaging portion 14 is provided, which is configured to come into frictional contact with a corresponding wall portion 15 of the recess 11a.
The state in which the engaging portion 14 and the wall portion 14 are engaged is the sixth state.
It can be seen in the handle 5a shown in solid lines on the left side of the figure.

In addition, in the above description, the engaging part 14 and the wall part 1
5 are in frictional contact with each other, however, an undercut portion or the like may be provided on either one of these to provide a structure for more secure engagement.

Moreover, if the engaging part 14 is formed relatively long along the longitudinal direction of the grip part 7a, the width of the part of the grip part 7a that the hand touches can be increased, and the engaging part 14 can be easily gripped by the hand. It can also serve as a means to do so.

Although this invention has been described above in detail in connection with the first and second embodiments, several modifications are possible within the scope of this invention.

For example, in the first embodiment, the handle 5 is later joined to the lid 1 by heat welding or the like.
When molding the lid 1, a pre-formed handle 5 is inserted into the mold so that the handle 5 is already joined to the lid 1 when the lid 1 is molded. You can.

Further, in each of the embodiments described above, the hinge 9 or 9a was formed along the attachment side connecting portion 8 or 8a. Therefore, the length of the hinge 9 or 9a can be increased, contributing to improved strength. However, if such an advantage is not desired, the mounting side connecting portion 8 or 8a should not have a corresponding portion. A hinge may be formed directly at the lower end of the vertical leg 6 or 6a.
