In order to better understand the present invention, a prior art battery fixing device will be described below.

Detailed ways

FIG. 1 shows a prior art electronic device or electronic instrument including a prior art battery holder. The prior art electronic device of FIG. 1 has a box-like housing composed of a body 1 and a cover 2 . One side of the housing cover 2 is hinged to one side of the housing 1 . The housing cover 2 can swing relative to the housing between a closed position and a fully open position. The housing cover 2 covers the open end of the housing 1 when it is in the closed position. The open end of the housing 1 is exposed when the housing cover 2 is in the fully open position.

The housing 1 has a recess 1a extending from its open end. When the housing cover 2 is in its closed position, the recess forms part of the interior or an interior space within the housing.

The battery 3 is placed in the groove of the casing 1 . Typically, the battery 3 is fastened to the wall of the housing 1 by means of an elastic band 4 . Both ends of the elastic band are connected to the wall of the housing 1 . The battery 3 can be moved into and out of its normal position fastened to the wall of the housing 1 by the strap 4 . Normally, the strap 4 is deformed as the battery moves in and out of its normal position. In this way, the battery 3 may become detached from the belt 4 .

The upper wall of the housing 1 is formed with a pair of bosses 5 and 6 extending in the recess 1a. The bosses 5 and 6 each have a screw hole.

Referring to Figures 1 and 2, the prior art battery holder includes a holder 9 made of metal. The holder 9 has an intermediate portion 9a, a joining portion 9b and a connecting portion 9c. The bonding portion 9b and the connection portion 9c are perpendicular to the middle portion 9a. The joint portion 9b and the connecting portion 9c each protrude in opposite directions from opposite sides of the intermediate portion 9a. The connection portion 9c has a pair of through holes through which the screws 7 and 8 pass, respectively. The screws 7 and 8 project into screw holes on the bosses 5 and 6, thereby engaging the walls of the bosses 5 and 6 forming the screw holes. The heads of the screws 7 and 8 are combined with the connecting portion 9c. In normal state, the connection part 9c is fixed on the bosses 5 and 6 by screws 7 and 8, and the joint part 9b cooperates with the middle part 9a to fix a corner of the upper end of the battery 3 relative to the wall of the housing 1 . Specifically, the joining portion 9b presses a part of the front surface of the upper end of the battery 3 against the wall of the case 1 , and the middle portion 9a joins a part of the upper end surface of the battery 3 . In this way, the holder 9 fixes the battery 3 on the wall of the housing 1 .

In this way, the battery 3 is firmly held in its normal position relative to the wall of the housing 1 by the holder 9 and the strap 4 .

In the prior art electronic equipment of FIGS. 1 and 2, the battery 3 is replaced as follows. Move the housing cover 2 to its fully open position. The screws 7 and 8 are loosened and moved away from the screw holes of the bosses 5 and 6 to allow the holder 9 to be completely disassembled and separated from the bosses 5 and 6 and the battery 3 . In this way, the battery 3 is released from the holder 9 . Next, the battery 3 is removed from the belt 4 . A new battery is placed in a normal position where it is fastened to the wall of the case 1 by the strap 4 . Then, the screws 7 and 8 are passed through the through holes of the connecting portion 9 c of the holder 9 . Place the ends of screws 7 and 8 over the entrances of the screw holes of bosses 5 and 6 while aligning screws 7 and 8 with the screw holes. Next, the screws 7 and 8 are tightened so that the holder 9 fixes the new battery on the wall of the housing 1 .

In the prior art electronic equipment of Figs. 1 and 2, in the process of changing the battery 3, the screws 7 and 8 and the holder 9 must be completely removed from the boss of the housing 1 before the battery 3 moves away from its normal position. Disassemble on 5 and 6. After the new battery is positioned, screws 7 and 8 must be put into the screw holes of bosses 5 and 6 again. Therefore, in the prior art electronic equipment of FIGS. 1 and 2, it is troublesome to replace the battery 3 with a new one. Furthermore, there is the possibility that the screws 7 and 8 or the holder 9 will be lost.

FIG. 3 shows an electronic device or electronic instrument including a battery fixing device according to an embodiment of the present invention.

The electronic device of FIG. 3 has a box-shaped case composed of a body 11 and a cover 12 . One side of the housing cover 12 is hinged to one side of the housing 11 . The housing cover 12 is swingable relative to the housing 11 between a closed position and a fully open position. The housing cover 12 covers the open end of the housing 11 when it is in the closed position. This open end of the housing 11 is exposed when the housing cover 12 is in its fully open position.

The housing 11 has a recess 11a protruding from its open end. When the housing cover 12 is in its closed position, the recess 11a forms part of the interior or an interior space within the housing.

A battery 13 is disposed in the groove of the casing 11 . In a normal state, the elastic band 14 fastens the battery 13 to the wall of the casing 11 . Both ends of the elastic band 14 are connected to the wall of the housing 11 . The battery 13 can be moved in and out of its normal position by the strap 14 fastening it to the wall of the housing 11 . Typically, the strap 14 is deformed as the battery moves in and out of its normal position. In this way, the battery 13 may become detached from the belt 14 .

The upper wall of the housing 11 is formed with a pair of bosses 15 and 16 extending in the recess 11a. The bosses 15 and 16 respectively have screw holes.

Referring to Figures 3, 4, 5 and 6, the battery holder includes a holder 19 made of a suitable material such as metal or resin. As can be seen more clearly below, the holder 19 is pivotable between a normal position and an inoperative position. The holder 19 has an intermediate portion 19a, a joining portion 19b and a connecting portion 19c. The bonding portion 19b and the connection portion 19c are perpendicular to the middle portion 19a. The bonding portion 19b and the connecting portion 19c protrude in opposite directions from opposite sides of the intermediate portion 19a, respectively. The connection portion 19c has a U-shaped groove 27 through which the screw 17 passes when the holder 19 is in the normal position. The connection portion 19c has a through hole 28 through which a screw passes. The screws 17 and 18 project into the screw holes on the bosses 15 and 16, thereby engaging with the walls of the bosses 15 and 16 on which the screw holes are formed. Thus, screws 17 and 18 are connected to bosses 15 and 16, respectively. In the case where the screws 17 and 18 are tightened when the holder 19 is in its normal position, the heads of the screws 17 and 18 are combined with the connecting portion 19c. Therefore, in this case, the screws 17 and 18 fix or firmly connect the connecting portion 19c to the bosses 15 and 16 . The joining portion 19b and the intermediate portion 19a constitute an L-shaped portion holding the battery 13 . In a normal state, the joint portion 19b cooperates with the middle portion 19a to fix one corner of the upper end of the battery 13 relative to the wall of the casing 11 . Specifically, the joint portion 19 b presses a part of the front surface of the upper end of the battery 13 against the wall of the case 11 , and the middle portion 19 a is combined with a part of the upper end surface of the battery 13 . In this way, the holder 19 serves to fix the battery 13 to the wall of the housing 11 .

The upper wall of the housing 11 is formed with a detent pin 20 extending in the groove 11a. The detent pin 20 is arranged relative to the cams 15 and 16 in such a way that the cam 15 protrudes between the detent pin 20 and the cam 16 . The connecting portion 19c of the retainer 19 has a contact portion 22 which engages or hits the stopper pin 20 . The contact portion 22 and the groove 27 are provided on opposite sides of the connection portion 19c of the holder 19, respectively. The contact portion 22 includes an inclined portion or an arcuate portion 29 which allows the contact portion to smoothly and gradually engage the detent pin 20 .

In a normal state, the contact portion 22 of the holder 19 is in a state of being combined with the stopper pin 20 . The engagement between the detent pin 20 and the contact portion 22 of the retainer 19 cooperates with the connection between the boss 16 and the connecting portion 19c of the retainer 19 to prevent clockwise rotation of the retainer 19 from its normal position. The connection between the boss 15 and the connecting portion 19c of the holder 19 cooperates with the connection between the boss 16 and the connecting portion 19c of the holder 19 to prevent counterclockwise rotation of the holder 19 from its normal position.

In the electronic equipment of Figs. 3-6, the battery 13 is replaced as follows. The housing cover 12 is moved to its fully open position. The screws 17 and 18 are loosened to a specified degree so that they remain engaged with the bosses 15 and 16 . The holder 19 is pulled out and moved away from its lowermost position. During this movement of the holder 19 , the contact portion 22 of the holder 19 moves out of the detent pin 20 . The retainer 19 is then pivoted clockwise about the screw 18 from its angled normal position to an inoperable position "P" (see FIG. 6 ). In this way, the holder 19 is completely separated from the battery. In other words, the battery is released from the holder. When the retainer 19 is turned clockwise to its inoperable position "P", the screw 17 is correspondingly moved out of the slot 27 in the connecting portion 19c of the retainer 19 . The retainer 19 does not interfere with the removal of the battery 13 from its normal position when in the inoperative position "P". Next, the battery is removed from the strap 14 . A fresh battery is moved to its normal position where it is fastened to the wall of the housing 11 by the strap 14 . Then, the holder 19 is rotated counterclockwise about the screw 18 from its inoperable position "P" until the screw 17 moves into the groove 27 of the connecting portion 19c of the holder 19 accordingly. Preferably, the counterclockwise rotation of the holder 19 continues until the holder 19 hits the screw 17 . Next, the screws 17 and 18 are tightened and the holder 19 is driven down to its lowermost position, where the holder 19 fixes the newly changed battery on the wall of the casing 11, and the contact of the holder 19 Portion 22 engages detent pin 20 on housing 11 .

In the process of replacing a new battery, it is not necessary to separate the screws 17 and 18 from the screw holes of the bosses 15 and 16 before removing the battery 13 . Furthermore, it is not necessary to place the screws 17 and 18 in the screw holes of the bosses 15 and 16 after the new battery has been positioned. Therefore, battery replacement on the electronic device of FIGS. 3-6 is easier than battery replacement on the prior art electronic device of FIGS. 1 and 2 . Also, the possibility of losing the screws 17 and 18 or the holder 19 during replacement of the new battery 13 can be eliminated.
