The base assembly 100 and play yard 1000 according to an embodiment of the present invention are described below with reference to fig. 1-5.

As shown in fig. 1, 2 and 3, the base assembly 100 of the play yard 1000 according to the embodiment of the first aspect of the present application comprises: a base 10, a plurality of bottom tubes 20 and a locking device 30.

The base assembly 100 has a folded state in which the plurality of base pipes 20 are folded under the base 10 to reduce the space occupation of the base assembly 100, facilitating the carrying and transportation of the base assembly 100 and the play yard 1000, and an unfolded state in which the plurality of base pipes 20 are unfolded around the base 10 to form a support portion of the bottom surface of the play yard 1000 for supporting the bottom surface of the play yard 1000 above the ground.

Referring to fig. 2, a projection of the base 10 toward a horizontal plane is circular or rectangular, a plurality of bottom pipes 20 are arranged around the base 10 (e.g., 4 or 6), one end of each bottom pipe 20 is rotatably connected to the base 10, and each bottom pipe 20 is rotated between an unfolded state and a folded state, such that the other ends of the plurality of bottom pipes 20 are disposed away from the base 10 in a horizontal direction in the unfolded state and are connected to the supporting legs 400 or the side pipes 200 of the play yard 1000 to form a frame for supporting the bottom surface of the play yard 1000, and in the folded state, the plurality of bottom pipes 20 are located below or laterally below the base 10 in a vertical direction to reduce a space occupation of the base assembly 100 in the horizontal direction in the folded state.

As shown in fig. 3, a locking device 30 is disposed on the base 10, the locking device 30 is used for locking at least one bottom tube 20 in the unfolded state to ensure that the base assembly 100 can be stably maintained in the unfolded state, that is, the locking device 30 is engaged with at least one bottom tube 20 (e.g., push-fit, snap-fit, plug-fit, etc.) to lock the bottom tube 20 in the unfolded state, and further, when the bottom tubes 20 are in the unfolded state, the locking device 30 is configured to release the bottom tube 20 when being lifted upwards, so as to switch the unfolded state of the bottom tubes 20 to the folded state by lifting the locking device 30.

It should be noted that each of the bottom tubes 20 has one end rotatably engaged with the base 10, and when at least one of the bottom tubes 20 is locked in the unfolded state, the base assembly 100 can be maintained in the unfolded state based on the connection relationship among the bed cloth covered on the play yard 1000, the side tubes 200 of the play yard 1000, the handrail tube 300 and the base assembly 100 in the unfolded state of the play yard 1000, and the locking device 30 of the present application can lock one or more of the bottom tubes 20 in the unfolded state, which is not particularly limited.

As shown in fig. 2, in the unfolded state, each bottom tube 20 is arranged to be inclined upward in a direction away from the base 10, and an angle α between each bottom tube 20 and the horizontal plane is between 1 and 10 degrees.

Therefore, in a daily use state, the bottom surface of the game bed 1000 can be relatively flat, and the ground on which the game bed 1000 is placed is not flat; or when a bias force is generated in the game space, the base pipe 20 and the base 10 can move upward synchronously to absorb the sinking amount through the ascending of the base 10 and the base pipe 20, so that the bottom surface of the game space is always kept flat, and the use experience of the game bed 1000 is improved.

According to the base assembly 100 of the game bed 1000 of the embodiment of the present application, at least one bottom tube 20 is locked by the locking device 30 when the plurality of bottom tubes 20 are in the unfolded state, and in the unfolded state, the bottom tube 20 has an included angle α of 1 to 10 degrees with the horizontal plane in the direction away from the base 10, and the specific position is 3 degrees, and the inclination angle of the bottom tube 20 is smaller and has a sinking amount towards the middle area, and in the daily use state, the bottom surface of the game bed 1000 can be relatively flat and slightly inclined towards the center, and when the game bed 1000 is subjected to a bias stress or the ground surface where the game bed 1000 is placed has a lower flatness, the base 10 and the bottom tube 20 can be lifted synchronously, and the preset sinking amount absorbs the lifting amount of the base 10 and the bottom tube 20, so as to avoid the middle area of the game bed 1000 from being raised, and ensure the flatness of the bottom surface, thereby improving the use experience of the game bed 1000.

It should be noted that, in the unfolded state of the bottom tube 20, in the direction away from the base 10, the angle between the bottom tube 20 and the horizontal plane may be 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, and the like, which all can achieve the above technical effects, and the description is omitted here, and the offset force refers to a local area on the bottom surface of the game bed 1000, for example: single-side stress, local stress on the upper left corner, the lower right corner and the like.
