Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery attachment device for a vehicle such as an automobile, and more particularly to improvements in a tray and bolt used for fixing a battery in an automobile or the like.

Conventionally, in order to attach a battery to a vehicle such as an automobile, it is placed in a tray 9 with a cross-sectional shape as shown in FIG. The clamp bolt 7 is engaged with the recessed portion having the fins 8, a presser plate is bridged over the top of the opposing clamp bolt 7 (not shown), and the top of the clamp bolt 7 is tightened with a nut or the like (not shown). According to this method, the battery is fixed on the tray 9. However, when this conventional mounting method is used, the operator must hold the clamp bolt 7 by hand until the clamp bolt 7 does not come off the tray 9 until the tightening is completed, so the tray is often This results in a problem that the clamp bolt 7 cannot be accurately fixed in the proper position of the clamp bolt 9.

The present invention has been made with the aim of solving the above-mentioned problems in the prior art.

The features of the structure of the present invention are that recesses are provided at certain points on the ridges at the bottom of both sides of the battery tray to prevent the clamp bolts from rotating and for positioning, and the clamp bolts are provided with claws to prevent the clamp bolts from falling. By providing the clamp bolt on the side of the battery tray, the clamp bolt cannot be tightened unless it is set in the correct position on the battery tray, and once set, the work can be carried out without having to hold the clamp bolt by hand. It's what I did.

Next, embodiments of the present invention will be described based on the drawings.

Fig. 1 is a longitudinal sectional view showing the order in which the present invention is carried out, Fig. 2 is an enlarged side view showing the mounting portion of the clamp bolt and tray after the clamp bolt has been installed, and Fig. 3 is the second FIG. 3 is a plan view of the attachment portion shown in the figure.

In the figure, reference numeral 1 indicates a part of the battery, which is placed on the bottom surface of a tray 2 which is shaped like a gutter and whose bottom center is curved downward. Then, the tray 2 is moved outward (towards the right in Fig. 1) at an appropriate location on its upper edge.
The clamp bolt 3 is made to bulge out to form claws 2', 2', and the clamp bolt 3 can be pushed between the claws 2', 2'. Further, a recess 2'' for accommodating the curved tip of the clamp bolt 3 is provided at the bottom edge of the tray 2 directly below the claws 2', 2', and the opening periphery of this recess 2'' is , opposed detents 2,2 are provided. The clamp bolt 3 is formed into a J-shape with a curved tip, and is connected to the claws 2' of the tray 2,
In FIG. 2, there are symmetrical claws 3',
3' is provided protrudingly. Now, in order to assemble the clamp bolt 3 to the tray 2, first, the claws 3', which are symmetrically protruded from the side surface of the clamp bolt 3,
3' around the upper surface of the claws 2', 2' of the tray 2, and then tighten the clamp bolt 3 to the claws 2', 2'.
2', and at the same time push the curved portion of the tip between the detents 2 and 2 of the recess 2'' of the tray 2, the curved tip of the clamp bolt 3 will not come off the recess 2'' of the tray 2. Clamp bolt 3 is tightened by tightening the upper nut.
The curved tip of the battery can be accurately fitted into the recess 2'' for positioning.Therefore, there is no need to hold the clamp bolt 3 by hand when fixing the battery, and the assembly can be done in the same way. The connecting fitting is bridged between the top end of the mating clamp bolt (not shown), and the work of tightening both bolts can be performed extremely easily and quickly.

Note that the claw 3' of the clamp bolt 3 is inserted between the tray detents 2 and 2.
The clamp bolts 3 are protruded symmetrically from both sides of the clamp bolt 3 at positions where the curved portions of the clamp bolts 3 are exposed. Also,
The opposing surfaces of the detents 2, 2 of the tray 2 are formed in the shape of horizontal walls so that they do not come off when the curved portion at the tip of the clamp bolt 3 is pushed in.

Since the present invention is constructed as described above, the clamp bolt 3 can be simply pushed between the claws 2' and 2' of the tray 2, eliminating the need to hold it by hand. This makes it possible to prevent problems such as incorrect assembly as shown in .
