Referring to Figs. 1 through5, the preferred embodiment of a connecting device 300 according to this invention connects a child safety seat 800 releasably to a retaining ring 10 on a vehicle seat 100, and is shown to include a housing 4, a rotating member 5, and a positioning member 6.
The housing 4 is includes a pair of left and right halves 41, 42 that are interconnected fixedly to define an accommodating space 43 therebetween. The rotating member 5 and the positioning member 6 are disposed within the accommodating space 43. The housing 4 has a rear end connected fixedly to the child safety seat 800. The left half 41 is generally U-shaped, and includes a vertical wall 410, a horizontal top wall 411, and a horizontal bottom wall 412. The vertical wall 410 has upper and lower ends that are formed respectively and integrally with the top and bottom walls 411, 412, and an inner surface that faces the right half 42 and that is formed with a recess 413.
The accommodating space 43 is defined between the inner surface of the left half 41 and the right half 42 of the housing 4, and is communicated with the recess 413 in the inner surface of the left half 41. Each of the left and right halves 41, 42 has a front end 44 and a rear end 45.
Each of the front ends 44 of the left and right halves 41, 42 is formed with a slot 46 that has an open front end, and a closed rear end.
The rotating member 5 has an outer periphery that is formed with a retaining groove 51 and a positioning unit 52 that is configured as a groove. The retaining groove 51 is defined between a rear retaining arm 511 and a front retaining arm 512 of the rotating member 5. The positioning unit 52 is defined between a lower positioning arm 521 and an upper positioning arm 522 of the rotating member 5. The lower positioning arm 521 is disposed between the upper positioning arm 522 end the rear retaining arm 511, and is adjacent to the rear retaining arm 511.
A pivot pin 53 extends through the rotating member 5, and is connected fixedly to the housing 4 so that the rotating member 5 is mounted rotatably within the housing 4. The rotating member 5 is rotatable about the pivot pin 53 between a release position shown in Fig. 3, where the rear retaining arm 511 extends into the slot 46, and a retaining position shown in Fig. 5.
A first biasing member 55 is disposed between the rotating member 5 and the housing 4, is configured as a coiled tension spring, and has a front end 551 inserted into a hole 57 in the rotating member 5, and a rear end 552 sleeved on a rivet 553 that extends through and that is connected fixedly to the left and right halves 41, 42 of the housing 4. As such, the first biasing member 55 can bias the rotating members to rotate to the release position shown in Fig. 3 so that the lower positioning arm 521 abuts against the bottom wall 412 of the left half 41 of the housing 4, thereby retaining the rotating member 5 at the release position.
The positioning member 6 is configured as an elongated vertical plate, and is formed with an integral tongue 61 at a front end thereof. Two guide pins 63 are fixed within the housing 4, are parallel to the pivot pin 53, and extend respectively through two pinholes 65 in the positioning member 6 so as to permit movement of the positioning member 6 on the guide pins 63.
Two second biasing members 67 are sleeved respectively on the guide pins 63, are configured as coiled compression springs, and are disposed between the left half 41 of the housing 4 and the positioning member 6 so as to bias the positioning member 6 to move from the recess 413 in the inner surface of the left half 41 of the housing 4 into the accommodating space 43. As such, when the rotating member 5 is disposed at the release position shown in Fig. 3 or the position shown in Fig. 4, the positioning member 6 is disposed at a disengaging position in the recess 413, and the tongue 61 of the positioning member 6 presses against a left side surface of the upper positioning arm 522 of the rotating member 5. When the rotating member 5 is disposed at the retaining position shown in Fig. 5, the positioning member 6 is disposed at an engaging position in the accommodating space 43 in the housing 4, and the tongue 61 of the positioning member 6 engages fittingly the positioning unit 52 of the rotating member 5 so as to prevent rotation of the rotating member 5 within the housing 4.
The right half 42 of the housing 4 is formed with a buttonhole 421 therethrough. A pushbutton 68 is disposed movably within the buttonhole 421 in the housing 4, and has a bifurcated inner end that abuts against the positioning member 6 and that is formed with a flange unit 681 extending radially and outwardly therefrom and having a diameter larger than that of the buttonhole 421 in the housing 4 so as to prevent removal of the pushbutton 68 from the buttonhole 421 in the housing 4. The second biasing members 67 bias the positioning member 6 to press the flange unit 681 of the pushbutton 68 against the right half 42 of the housing 4. As such, the pushbutton 68 is operable to move along a direction parallel to the pivot pin 53 so as to move the positioning member 6 from the engaging position to the disengaging position.
During assembly, the retaining ring 10 is inserted into the slots 46 in the left and right halves 41, 42 of the housing 4, as shown in Fig. 3. Subsequently, the retaining ring 10 is moved from the front ends of the slots 46 to the rear ends of the slots 46 so as to contact and rotate the rear retaining arm 511 of the rotating member 5, thereby engaging the retaining groove 51 in the rotating member 5, as shown in Fig. 4. When the retaining ring 10 reaches the rear ends of the slots 46, the rotating member 5 is disposed at the retaining position shown in Fig. 5, where the positioning member 6 is biased by the second biasing member 67 to move from the disengaging position to the engaging position and where the tongue61Of the positioning member 6 engages the positioning unit 52 so as to confine the retaining ring 10 within the retaining groove 51 in the rotating member 5 and between the rotating member 5 and the housing 4, thereby retaining the retaining ring on the housing 4. As such, the assembly of the retaining ring 10 and the connecting device 300 of this invention can be conducted with ease.
When it is desired to remove the retaining ring 10 from the connecting device 300 of this invention, the pushbutton 68 is pressed so as to move the positioning member 6 from the engaging position to the disengaging position, thereby permitting the first biasing member 55 to rotate the rotating members from the retaining position to the release position.
