Title: JOINT DEVICE

The invention relates to a joint device, more particularly to a joint device for use in a baby basket. A conventional baby basket is used to carry an infant, and includes a basket, a handle, and a joint device that interconnects rotatably the basket and the handle. The handle can be locked relative to the basket at an unfolded position by the joint device, where a distal portion of the handle is distal from the basket. To fold the handle relative to the basket, a pushbutton of the joint device needs to be pressed constantly to unlock the handle, such that the handle can be rotated relative to the basket to a folded position, where the distal portion of the handle is close to the basket. The abovementioned operation needs to be achieved by both hands of a user, and is inconvenient for the user.

Therefore, the object of the present invention is to provide a joint device that can overcome the aforesaid drawbacks associated with the prior arts.

Accordingly, a joint device of the present invention includes a first, mounting seat, a second mounting seat, a latch member, an operating member and a retention unit. The first mounting seat is formed with at least one first locking groove. The second mounting seat is connected to the first mounting seat, is formed with at least one second locking groove, and is rotatable relative to the first mounting seat about a first axis. The second locking groove is ahgned with the first locking groove in a direction of the first axis when the second mounting seat is at an unfolded position relative to the first mounting seat. The second locking groove is misaligned from the first locking groove when the second mounting seat leaves the unfolded position. The latch member has at least one latch portion, and is movable along the first axis between the first and second mounting seats. The latch portion of the latch member engages the first locking groove and the second locking groove to prevent the rotation of the second mounting seat relative to the first mounting seat when the latch member is at a locking position. The latch portion of the latch member engages the first locking groove and is disengaged from the second locking groove to permit the rotation of the second mounting seat relative to the first mounting seat when the latch member is at an unlocking position. The operating member is coupled to the latch member, and is capable of being driven to move along the first axis toward the first mounting seat to drive movement of the latch member from the locking position to the unlocking position so that the second mounting seat can leave the unfolded position. The retention unit is configured to hold the latch member at the unlocking position in response to the movement of the latch member driven by the operating member from the locking position to the unlocking position to permit the rotation of the second mounting seat relative to the first mounting seat when the second mounting seat is at the unfolded position.

Before the present invention is described in greater detail, it should be noted that hke elements are denoted by the same reference numerals throughout the disclosure.

Referring to Figs. 1 and 2, a baby basket is shown to include a basket la, a handle lb, and two first preferred embodiments of joint devices 100 according to the present invention that interconnect rotatably the basket la and the handle lb.

Referring further to Figs. 3 to 9, the first preferred embodiment includes a first mounting seat 1, a second mounting seat 2, a latch member 3, a retention unit 4, an operating member 5, a first resilient member 6 and a second resilient member 7.

The first mounting seat 1 has a first mounting segment 10 that is mounted with the basket la, and a first shaft segment 13 that extends along a first axis (A) (see Fig. 6). The second mounting seat 2 has a second mounting segment 20 that is mounted with the handle lb, and a second shaft segment 23 that extends along the first axis (A) (see Fig. 6), that is connected to and inserted into the first shaft segment 13, and that is rotatable relative to the first shaft segment 13 about the first axis (A), such that the second mounting seat 2 is rotatable relative to the first mounting seat 1 about the first axis (A) between an unfolded position (see Fig. 1) and a folded position (see Fig. 2). A distal portion of the handle lb is distal from the basket la when the second mounting seat is at the unfolded position, and is close to the basket la when the second mounting seat is at the folded position.

The first mounting seat 1 is formed with two first locking grooves 11 that are opposite to each other in a direction perpendicular to the first axis (A), and a plurality of first auxiliary locking grooves 12. The first locking grooves 11 and the first auxihary locking grooves 12 are angularly-arranged about the first axis (A).

The second mounting seat 2 is formed with two second locking grooves 21 that are opposite to each other in a direction perpendicular to the first axis (A), and a plurality of second auxiliary locking grooves 22. The second locking grooves 21 and the second auxiliary locking grooves 22 are angularly-arranged about the first axis (A). Each of the second locking grooves 21 is ahgned with a respective one of the first locking grooves 11 in the direction of the first axis (A) when the second mounting seat 2 is at the unfolded position, and is misahgned from the respective one of the first, locking grooves 11 in the direction of the first axis (A) when the second mounting seat 2 leaves the unfolded position. Each of the second auxiliary locking grooves 21 is aligned with a respective one of the first auxihary locking grooves 11 in the direction of the first axis (A) when the second mounting seat 2 is at the unfolded position, and is misaligned from the respective one of the first auxiliary locking grooves 11 in the direction of the first, axis (A) when the second mounting seat 2 leaves the unfolded position. The second mounting seat 2 is further formed with a plurality of extension holes 2a and a plurality of communication holes 2b (see Fig. 4). In this embodiment, the extension holes 2a and the communication holes 2b are arranged alternately and angularly about the first axis (A).

The latch member 3 has a circular body 33 that is centered at the first axis (A), two latch portions 32 that are opposite to each other in a direction perpendicular to the first axis (A), and a plurality of auxihary latch portions 31. The latch portions 32 and the auxihary latch portions 31 are disposed on a periphery of the circular body 33.

The latch member 3 is disposed movably between the first and second mounting seats 1, 2. The circular body 33 of the latch member 3 is formed with a through hole 3b for extension of the first and second shaft segments 13, 23 of the first and second mounting seats 1, 2. The latch member 3 is movable along the first axis (A) between a locking position (see

Fig. 6) and an unlocking position (see Fig. 7) when the second mounting seat 2 is at the unfolded position.

When the latch member 3 is at the locking position, each of the latch portions 32 of the latch member 3 engages a respective one of the first locking grooves 11 and the respective one of the second locking grooves 21 aligned with the respective one of the first locking grooves 11 to prevent the rotation of the second mounting seat 2 relative to the first mounting seat 1, and each of the auxiliary latch portions 31 of the latch member 3 engages a respective one of the first auxiliary locking grooves 12 and the respective one of the second auxiliary locking grooves 22 aligned with the respective one of the first auxiliary locking grooves 12.

When the latch member 3 is at the unlocking position, each of the latch portions 32 of the latch member 3 engages the respective one of the first locking grooves 11 and is disengaged from the respective one of the second locking grooves 21 to permit the rotation of the second mounting seat 2 relative to the first mounting seat 1, and each of the auxiliary latch portions 31 of the latch member 3 engages the respective one of the first auxiliary locking grooves 12 and is disengaged from the respective one of the second auxiliary locking grooves 22. Each of the first and second auxiliary locking grooves 12, 22 has a dimension smaller than that of each of the latch portions 32 of the latch member 3 to prevent the latch portions 32 from being engaged therewith when the second mounting seat 2 leaves the unfolded position.

The operating member 5 is movable along the first axis (A), is co-rotatable with the second mounting seat 2, and has a button portion 51 that is disposed at one side of the second mounting seat 2 opposite to the latch member 3, and a plurality of rod portions 52, each of which extends from a periphery of the button portion 51 and through a respective one of the extension holes 2a in the direction of the first axis (A). The button portion 51 of the operating member 5 is capable of being pressed to move toward the first mounting seat 1 to drive the rod portions 52 to push the latch member 3, and to drive movement of the latch member 3 from the locking position to the unlocking position when the second mounting seat 2 is at the unfolded position.

The first resilient member 6 has opposite ends arranged along the first axis (A) and connected respectively to the first mounting seat 1 and the latch member 3 for biasing the latch member 3 away from the first mounting seat 1 toward the locking position. In this embodiment, the first resilient member 6 is configured as a compression spring.

The second resilient member 7 has opposite ends arranged along the first axis (A) and connected respectively to the second mounting seat 2 and the operating member 5 for biasing the operating member 5 away from the latch member 3 to return to its initial position when the button portion 51 of the operating member 5 is released. In this embodiment, the second resilient member 7 is configured as a compression spring.

The retention unit 4 includes a plurality of barb-shaped first hooks 41 and a plurahty of barb-shaped second hooks 42. The second hooks 42 are connected fixedly to an outer surrounding surface of the first shaft segment 13 of the first mounting seat 1. Each of the first hooks 41 extends from the periphery of the button portion 51 of the operating member 5 through a respective one of the communication holes 2b in the direction of the first axis (A).

The first hooks 41 correspond respectively in angular position to the second hooks 42 when the second mounting seat 2 is at the unfolded position, and are spaced apart from the second hooks 42 along the first axis (A) when the latch member 3 is at the locking position. When the button portion 51 of the operating member 5 is pressed to move toward the first mounting seat 1 to drive the movement of the latch member 3 from the locking position to the unlocking position, the button portion 51 simultaneously drives the first hooks 41 to move toward the first mounting seat 1 to engage respectively the second hooks 42, such that the operating member 5 and the first hooks 41 are prevented from moving away from the first, mounting seat 1 through the engagement between the first and second hooks 41, 42 to hold the latch member 3 at the unlocking position to permit the rotation of the second mounting seat 2 relative to the first mounting seat 1 when the second mounting seat 2 is at the unfolded position and when the operating member 5 is released. The latch member 3 is further formed with a plurality of through grooves 3a that are in spatial communication with the through hole 3b for receiving respectively the second hooks 42 when the latch member 3 is at the unlocking position.

When the second mounting seat 2 rotates relative to the first mounting seat 1 to leave the unfolded position, each of the first hooks 41 is misahgned from the respective one of the second hooks 42 in the direction of the first axis (A) to be disengaged from the respective one of the second hooks 42 to release the latch member 3. At this time, the latch member 3 is biased by the first resilient member 6 to abut against the second mounting seat 2 and is prevented from moving to the locking position due to the misahgnment between the first and second locking grooves 11, 21, and the operating member 5 is biased to move away from the first mounting seat 1 to its initial positions by the second resilient member 7 to separate the first hooks 41 from the second hooks 42 along the first axis (A), such that when the second mounting seat 2 rotates back to the unfolded position, the first hooks 41 cannot engage the second hooks 42 to hold the latch member 3 at the unlocking position, and the latch member 3 is biased by the first resilient member 6 to the locking position.

To sum up, by virtue of the retention unit 4, the latch member 3 can be moved from the locking position to the unlocking position, and be retained at the unlocking position to permit the rotation of the second mounting seat 2 relative to the first mounting seat 1 through a single depression operation of the operating member 5 when the second mounting seat is at the unfolded position. Referring back to Figs. 1 and 2, in this invention, during a fold operation of the handle lb relative to the basket la, the operating member 5 of one of the joint devices 100 is depressed to drive the latch member 3 of the one of the joint device 100 to be held at the unlocking position, and the operating member 5 of the other one of the joint devices 100 is subsequently depressed to drive the latch member 3 of the other one of the joint device 100 to be held at the unlocking position. Then, the handle lb can be rotated relative to the basket la to the folded position. The abovementioned fold operation can be achieved by only one hand of a user, and is more convenient than that of the conventional baby basket.

Referring to Figs. 10 to 15, a second preferred embodiment of the joint device 100 according to the present invention is similar to the first preferred embodiment. What is different, is that the retention unit 4’ of the second preferred embodiment includes a locking groove 42’, a locking block 41’ and a third resilient member 43’.

The locking groove 42’ is formed in one of the latch portions 32 of the latch member 3.

The locking block 41’ is mounted to the second mounting seat 2, and is movable relative to the second mounting seat 2 along a second axis (B) (see Fig. 12) of the second mounting seat 2 that is oblique to the first axis (A).

The third resilient member 43’ has opposite ends arranged along the second axis (B) and connected respectively to the locking block 41’ and the second mounting seat 2 for biasing the locking block 41’ toward the latch member 3. In this embodiment, the third resilient member 43’ is configured as a compression spring.

The locking groove 42’ is aligned with the second axis (B) when the second mounting seat 2 is at the unfolded position and when the latch member 3 is at the unlocking position (see Fig. 13), such that the locking block 41’ is biased by the third resilient member 43’ to engage the locking groove 42’ to hold the latch member 3 at the unlocking position in response to the movement of the latch member 3 from the locking position to the unlocking position driven by the operating member 5 to permit the rotation of the second mounting seat 2 relative to the first mounting seat 1.

The first mounting seat 1 is further formed with a first groove lc that is registered with the locking groove 42’ when the latch member 3 is at the unlocking position. The second mounting seat 2 is further formed with a second groove 2c for extension of the locking block 41’ therethrough.

The first mounting seat 1 has a groove defining surface that defines the first groove lc. The locking block 41’ has an inclined surface 413’ for contacting slidably the groove defining surface of the first mounting seat 1, so that the locking block 41’ is pushed by the groove defining surface to be smoothly disengaged from the locking groove 42’ to release the latch member 3 when the second mounting seat 2 leaves the unfolded position.

The locking block 41’ further has an abutment surface 412’ for contacting the groove defining surface when the second mounting seat 2 is at the unfolded position, so as to hmit the rotation angle of the second mounting seat 2 relative to the first mounting seat 1.

Referring to Fig. 13, it is noted that there is a gap (G) between the latch member 3 and an interior end surface 25 of the second mounting seat 2 when the latch member 3 is at the unlocking position and when the second mounting seat 2 is at the unfolded position. Therefore, when the second mounting seat 2 leaves the unfolded position, the latch member 3 is released by the retention unit 4’ and is biased by the first resilient member 6 to move to an intermediate position, where the latch member 3 abuts against the interior end surface 25 of the second mounting seat 2 and is prevented from moving to the locking position due to the misalignment between the first and second locking grooves 11, 21, and where the locking groove 42’ is not registered with the first groove lc (i.e., the locking groove 42’ is misahgned from the second axis (B) when the second mounting seat 2 is at the unfolded position), such that the locking block 41’ cannot engage the locking groove 42’ to hold the latch member 3 at the unlocking position and the latch member 3 is biased back to the locking position by the first resilient member 6 when the second mounting seat 2 rotates back to the unfolded position.

Referring to Figs. 16 to 18, a third preferred embodiment of the joint device 100 according to the present invention is similar to the second preferred embodiment. The retention unit 4” of the third preferred embodiment also includes a locking groove 42”, a locking block 41” and a third resilient member 43”. What is different, is that the locking block 41” of the retention unit 4” is formed with a retaining groove 41a” that extends along the second axis B. The second mounting seat 2 further has a protrusion 2d that is retained in the retaining groove 41a”. The third resilient member 43” is retained in the retaining groove 41a”, and has opposite ends connected respectively to the locking block 41” and the protrusion 2d for biasing the locking block 41” toward the latch member 3.

Referring to Fig. 18, like the second preferred embodiment, there is a gap (G) between the latch member 3 and the interior end surface 25 of the second mounting seat 2 when the latch member 3 is at the unlocking position and when the second mounting seat 2 is at the unfolded position. Therefore, when the second mounting seat 2 leaves the unfolded position, the latch member 3 is biased by the first resilient member 6 to move to an intermediate position, where the latch member 3 abuts against the interior end surface 25 of the second mounting seat 2, such that the locking block 41” cannot engage the locking groove 42” to hold the latch member 3 at the unlocking position when the second mounting seat 2 rotates back to the unfolded position.

It is noted that, in the second and third preferred embodiments of this invention, the operating member 5 may be configured not to be co-rotatable with the second mounting seat 2 (i.e., the operating member 5 may not rotate about the first axis (A) when the second mounting seat 2 rotates relative to the first mounting seat 1).
