Furthermore, features defining "first", "second" may include one or more such features, either explicitly or implicitly. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the embodiment of the present invention, the exercise frame 1000 is a foldable exercise frame, and the exercise frame 1000 may have two basic configurations, one is a use configuration and one is a storage configuration. Some exercise frames 1000 can have various functions when in use, and the use modes of the exercise frames 1000 can be divided into various modes according to different functions.

Since both the connection rod 300 and the backrest 500 can be rotated with respect to the base 200, the connection rod 300 and the backrest 500 can be rotated to positions corresponding to the form of the exercise frame 1000, respectively, in use. For this purpose, in the embodiment of the present invention, a lever set switching and fastening mechanism 100 is provided between at least one base 200 and the backrest 500, and the lever set switching and fastening mechanism 100 is configured to lock the backrest 500 when the backrest 500 is rotated to a set backrest angle with respect to the base 200. Also, a lever set switching and clamping mechanism 100 is provided between at least one of the bases 200 and the connecting lever 300, and the lever set switching and clamping mechanism 100 is configured to lock the connecting lever 300 when the connecting lever 300 rotates to a set lever angle with respect to the base 200.

For convenience of description, the rod group switching and fastening mechanism 100 between the backrest 500 and the base 200 is referred to as a first adjustment mechanism 100a, and the rod group switching and fastening mechanism 100 between the connection rod 300 and the base 200 is referred to as a second adjustment mechanism 100b. The deformation function of the exercise frame 1000 with the participation of the two mechanisms is described below using an example of the exercise frame 1000 shown in fig. 1-5.

In this example, the exercise frame 1000 has four variations, fig. 1 shows the storage configuration of the exercise frame 1000, fig. 2 shows the exercise configuration of the exercise frame 1000, fig. 4 shows the seating configuration of the exercise frame 1000, and fig. 5 shows the half-recliner configuration of the exercise frame 1000.

In the storage configuration, as shown in fig. 1, the connection bars 300 are substantially parallel to the base 200, two connection bars 300 are positioned between two base 200, the backrest 500 is also substantially parallel to the base 200, and the backrest 500 is folded over the base 200.

In the exercise mode, as shown in fig. 2, the upper ends of the two connection rods 300 are rotated to the front sides of the two bases 200, the angle between the connection rods 300 and the bases 200 is an obtuse angle, the upper ends of the backrest 500 can be rotated to the rear sides of the two bases 200, and the backrest 500 is substantially at an obtuse angle with respect to the bases 200.

In the seat configuration, as shown in fig. 4, the connecting rod 300 is generally perpendicular to the base 200 and the backrest 500 is also generally perpendicular to the base 200.

In the semi-reclining chair configuration, as shown in fig. 5, the connecting rod 300 is substantially perpendicular to the bases 200, and the upper ends of the backrest 500 are rotatable to the rear sides of the two bases 200, the backrest 500 being substantially at an obtuse angle to the bases 200. The angle between the backrest 500 and the base 200 in fig. 5 is smaller than the angle between the backrest 500 and the base 200 in fig. 2.

In the above four configurations of the exercise frame 1000, the backrest 500 has four angular positions with respect to the base 200, and the four angular positions are all set back angles of the backrest 500, so that the first adjusting mechanism 100a can be said to have four shift positions when adjusting the angle of the backrest 500. At these four set back angles, the first adjustment mechanism 100a can lock the back 500 to the base 200.

In the above four modes of the exercise frame 1000, the connecting rod 300 has three angular positions with respect to the base 200, and the three angular positions are all set lever angles of the connecting rod 300, so that the connecting rod 300 can be said to have three gears when being angularly adjusted. At these three set lever angles, the second adjustment mechanism 100b can lock the connecting lever 300 to the base 200.

For example, in one specific example, in the storage configuration: the included angle between the table 400 and the connecting rod 300 is about 0 degrees, the included angle between the connecting rod 300 and the base 200 is about 0 degrees, and the included angle between the backrest 500 and the base 200 is about 0 degrees;

the body building shape is as follows: the included angle between the table 400 and the connecting rod 300 is about 90 degrees, the included angle between the connecting rod 300 and the base 200 is about 150 degrees, and the included angle between the backrest 500 and the base 200 is about 150 degrees;

in the seat configuration: the included angle between the backrest 500 and the base 200 is about 90 degrees, the included angle between the connecting rod 300 and the base 200 is about 90 degrees, and the included angle between the table 400 and the connecting rod 300 is about 90 degrees;

in the semi-reclining chair configuration: the angle between the backrest 500 and the base 200 is about 120 deg., and the angle between the table 400 and the connecting rod 300 is about 90 deg..

Of course, in the embodiment of the present invention, the set rod angle of the connecting rod 300 relative to the base 200 is not limited to the above three angle positions, the connecting rod 300 can have more set rod angles relative to the base 200, and the included angle between the connecting rod 300 and the base 200 at each set rod angle is not limited to the above angle values; also, the set backrest angle of the backrest 500 with respect to the base 200 may not be limited to the four angular positions described above, and the backrest 500 may have more set backrest angles with respect to the base 200, and the angle between the backrest 500 and the base 200 at each set backrest angle is not limited to the above-described angle values. For convenience of explanation, the following description will be given by taking the example in which the first adjusting mechanism 100a locks the backrest 500 when the backrest 500 is rotated to the four set backrest angles, and the second adjusting mechanism 100b locks the connecting rod 300 when the connecting rod 300 is rotated to the three set rod angles.

In some embodiments, as shown in fig. 1-5, two ends of the table 400 are rotatably connected to upper ends of two connecting rods 300, respectively, and a third adjusting mechanism 700 is provided between an upper end of at least one connecting rod 300 and the table 400, and the third adjusting mechanism 700 is configured to lock the table 400 when the table 400 is rotated to a set table angle relative to the connecting rod 300. In the example of fig. 1, the table 400 is disposed parallel to the connecting rod 300 in the storage configuration, and in the examples of fig. 2-5, the table 400 is disposed perpendicular to the connecting rod 300 in the exercise configuration, the seating configuration, and the semi-reclining chair configuration. In the above four configurations of the exercise frame 1000, the table 400 has two angular positions with respect to the connecting rod 300, and the two angular positions are set table angles of the table 400, so that the table 400 can be said to have two gears when the angles are adjusted. At both of these set table angles, the third adjustment mechanism 700 can lock the table 400 to the connecting rod 300.

In one specific example, as shown in fig. 3, the table 400 is a dinner plate of a body-building frame, the table 400 includes a dinner plate cover 420 and a music panel 410, the dinner plate cover 420 is detachably disposed on the music panel 410, and two ends of the music panel 410 are rotatably connected to two connecting rods 300. Wherein, as shown in fig. 2, when the exercise rack 1000 is in the exercise configuration, the dinner plate cover 420 is detached from the music panel 410. As shown in fig. 1, 4 and 5, the dinner plate cover 420 is mounted on the music panel 410 when the exercise rack 1000 is in the storage, seating and semi-reclining configurations.

As can be seen from the above description, the exercise frame 1000 according to the embodiment of the invention has various shapes, can provide multiple use functions for infants, and has strong practicability. And the body-building frame 1000 is not easy to overturn, safe and reliable when in use due to the supporting function of the supporting frame 600.

In particular, and still taking the embodiment shown in fig. 1-5 as an example, the exercise rack 1000 may be configured with a cloth cover, and when the exercise rack 1000 is in the storage configuration shown in fig. 1, the cloth cover may be sleeved on the backrest 500, and the base 200, the connecting rod 300, the table 400 and the backrest 500 are all disposed substantially in parallel, and the backrest 500 covers the cloth cover on the table 400.

When the exercise frame 1000 is in the exercise configuration shown in fig. 2, the cloth cover can be covered on the support frame 600, an infant can lie on the cloth cover on the support frame 600 (equivalent to lying on the ground), then the music panel 410 is stepped on by the feet, and the U-shaped backrest 500 can be held.

When the exercise frame 1000 is in the seating configuration shown in fig. 3, the cloth cover may be covered on the backrest 500, and an infant may sit on the ground between the backrest 500, the base 200 and the connection rod 300 and then lie on the table 400 for dining.

When the exercise rack 1000 is in the semi-reclining chair configuration shown in fig. 4, the cloth cover still covers the backrest 500, and an infant can rest on the cloth cover in a semi-reclining position.

The structural composition of the key components of exercise frame 1000 will be described below in conjunction with the accompanying drawings.

In the embodiment of the invention, when the exercise frame 1000 is used, the front end of the support frame 600 is connected with the rear ends of the bases 200, and the support frame 600 and the two bases 200 are positioned on the same horizontal plane, so that the support frame 600 can increase the grounding length of the bases 200, and the exercise frame 1000 can not be turned over due to unstable gravity center when the chair form or the half-reclining chair form of the exercise frame 1000 is used, thereby improving the use safety of the exercise frame 1000.

The support frame 600 is movably coupled to the base 200 such that the support frame 600 can be unfolded or stored on the exercise frame 1000.

In some embodiments, the support frame 600 is detachably connected to the base 200, such that the support frame 600 can be detached from the base 200 when the exercise frame 1000 is received; when the body-building frame 1000 is in use, the support frame 600 can be installed at the rear end of the base 200. In the embodiment of the present invention, the support 600 may be detachably coupled to the base 200 in various structures.

For example, in one specific example shown in fig. 6 and 7, two ends of the support frame 600 are respectively connected to the base 200 by fastening boxes 610. The bottom of the base 200 is provided with a bottom groove 210 that is opened downwards, and the clamping box 610 is connected in the bottom groove 210 in a snap-fit manner, so that when the support 600 is assembled, the bottom surface of the support 600 can be leveled with the bottom surface of the base 200.

Specifically, as shown in fig. 7, a peripheral wall of one side of the bottom groove 210 is provided with an insertion hole 220, the clamping box 610 is provided with an insertion block 611 inserted into the insertion hole 220, and in fig. 7, a peripheral wall of the front side of the bottom groove 210 is provided with two insertion holes 220.

More specifically, as shown in fig. 7, a hook 230 is disposed in the bottom slot 210, the hook 230 extends into the clamping box 610, a clamping pin 612 and a reset member (not shown) are disposed in the clamping box 610, the clamping pin 612 is movable between a clamping position, in which the clamping pin 612 cooperates with the hook 230 to lock the clamping box 610, and a releasing position, in which the clamping pin 612 is separated from the hook 230, and the reset member is connected between the clamping box 610 and the clamping pin 612 to normally drive the clamping pin 612 to move toward the clamping position, and the clamping pin 612 has a pulling block 6121 extending downward out of the clamping box 610. The reset element is a spring, and the spring is arranged at the rear end of the clamping pin 612 and is used for normally driving the clamping pin 612 to slide forwards.

Thus, as shown in fig. 6, when the clamping box 610 is to be removed, the pulling block 6121 can be pulled backward at the bottom of the clamping box 610 to pull the clamping pin 612 to the releasing position, so that the clamping pin 612 is released from the clamping hook 230. The insert 611 of the cartridge 610 is then pulled out of the receptacle 220 of the base 200, and the cartridge 610 can be removed from the base 200.
