Patent Grant
12303731
The present disclosure relates to the technical field of sports equipment, in particular to a wall-mounted fly wall rack.
Smith machine and big and small bird exercisers are two kinds of fitness equipment that must be equipped in the exercise field and gym. However, having these two exercisers at the same time is too expensive and takes up too much space, which is not suitable for use in places with limited space such as home.
Although there are comprehensive exercisers combining Smith machine and small fly exerciser in the market, Smith machine and small fly exerciser are simply superimposed and combined together, and they do not have the function of mutual conversion. For this kind of machines, because they include all the necessary components of Smith machine and small fly exerciser, the manufacturing cost is not less than that of two separate machines, and they are huge.
The U.S. Pat. No. 933,387 discloses a “Slidable bar and carriage exercise assembly”, which includes a Smith bar as a part of a multifunctional exerciser, and uses the Smith bar instead of free weight to use a selectable weight stack to resist movement resistance. U.S. patent Ser. No. 12/011,635 puts forward “Multifunctional comprehensive training device capable of being grasped stably”, which can use the same set of selected barbells for Smith mechanism and cable mechanism through brackets, hangers and other parts.
However, when the exerciser disclosed above is doing flying exercise, the fitness equipment cannot adjust or switch the exercise posture and angle at will according to its own needs. At the same time, this fitness equipment is too bulky to be used in a smaller area than the traditional gym, and its manufacturing cost is not less than that of two separate exercise equipment.

The adjustable locking mechanism 30 includes a pivot arm 31 and a fixed arm 34. The pivot arm 31 is provided with a locking member 33 and a pivot shaft 32, and the fixed arm 34 is provided with a pivot disk 35 and a mounting seat 60. The pivot arm 31 is rotatably connected with the pivot disk 35 through the pivot shaft 32; and the pivot arm 31 horizontally rotates relative to the pivot disk 35 within a limited angle range. The pivot disk 35 is provided with a plurality of fixing holes 35-1 for insertion of the locking member 33 along the rotation direction of the pivot arm 31. The pivot arm 31 can be selectively positioned at one of a plurality of rotation angles through the locking member 33, and the fixed arm 34 is installed on the wall through the mounting seat 60.
When the movable frame 20 horizontally rotates to the open state relative to the fixed frame 10, the pivot arm 31 of the movable frame 20 is arranged vertically to the wall along the length direction and locked by the locking member 33. At this time, the movable frame 20 is at a position of 90 degrees, and the connecting rod 40 is installed at the top ends of the two movable frames 20, providing certain stability to the two movable frames 20. When the movable frames 20 horizontally rotate to the storage state relative to the fixed frame 10, the connecting rod 40 is disengaged from the top ends of the two movable frames 20, the locking member 33 is unlocked from the locked state to the open state, and the pivot arms 31 of the movable frames 20 are arranged parallel to the wall along the length direction. At this time, the movable frames 20 are at the position of 0 or 180 degrees.
As shown in
Specifically, the elastic locking member 33-1 of the pivot arm 31 is unlocked from the locked state, and then the pivot arm 31 of the movable frame 20 is rotated to an appropriate angle with respect to the pivot disk 35 of the fixed frame 10. At this time, the elastic locking member 33-1 automatically rebounds to lock the pivot arm 31 on the pivot disk 35, and the movable frame 20 forms an angle suitable for exercise with respect to the fixed frame 10, which is convenient for users to exercise. The locking member 33 of the second pivot arm 31-B is a pin member, and the pin member is inserted into the pivot disk 35, which can not only improve the stability of the whole structure when the movable frame 20 is locked relative to the fixed frame 10, but also facilitate the adjustment of the angle.
In this embodiment, the movable frame 20 is connected to the pivot arm 31 by bolts passing through the movable frame 20, and the fixed frame 10 is connected to the fixed arm 34 by bolts passing through the fixed frame 10. In some embodiments, not shown in the drawings, the connection between the movable frame 20 and the fixed frame 10 and the arm is not limited to bolt connection, but can be customized according to specific application requirements, such as threaded connection, welding or riveting. Compared with the other two connection methods, welding can make the connection between the two parts more firm and improve the strength of the overall structure.

The existence of the connecting rod 40 can make the present disclosure have a pull-up exercise environment, and the existence of the limit sheet 41 makes the connecting rod 40 not rotate with the user's hard work when using the present disclosure for pull-ups; When a user wants to use the present disclosure to do fly exercise, the connecting rod 40 can be detached from the movable frame 20 by operating the fixing bolts 43, and then the movable frame 20 is operated to adjust it to a proper angle for exercise.
Specifically, firstly, two movable frames 20 are horizontally rotated and unfolded along the pivot disk, so that the length direction of the movable frames 20 is perpendicular to the wall and overhangs outward, and then the locking member 33 is inserted into the fixing hole 35-1 of the pivot disk 35, which plays a role in reliably positioning the movable frames 20, and ensures that the movable frames 20 are stably kept in a state of extending vertically parallel to the wall during unfolding. Then, the connecting rod 40 is connected with the top end of the movable frame 20, and both ends of the connecting rod 40 are fastened with fixing bolts 43 to prevent the connecting rod 40 from falling off. The existence of the fixing bolts 43 realizes the flexible disassembly and assembly between the connecting rod 40 and the movable frame 20.
In some embodiments, not shown in the figure, the connecting rod 40 may be a hollow circular tube or a hollow square tube. The hollow design can not only maintain a certain strength, but also reduce the material cost in production, and because it is hollow, the quality is also reduced to a certain extent, and the transportation cost can also be reduced. The square design can make the connecting rod 40 not rotate with the user's effort when the user performs pull-up exercise.

The handle pulley block 70 includes a handle 71, a pull rope 72, a sleeve 73 and a pulley seat 75. The handle pulley block 70 is slidably sleeved on the movable frame 20 through the sleeve 73, and a plurality of adjusting jacks 20-1 are arranged on the movable frame 20 in the vertical direction. The sleeve 73 can be selectively slidably positioned at any adjusting jack 20-1 position of the movable frame 20 through an adjusting pin 74. A first pulley 75-1 and a second pulley 75-2 are rotatably connected to the pulley seat 75, and a gap through which the pull rope 72 passes is reserved between the first pulley 75-1 and the second pulley 75-2;
The pull rope 72 extends from the handle 71, passes through the pulley assembly, the first guide pulley 77, the adjusting pulley 76, the pulley rack 79 and the pivot shaft 32 in turn, and is connected to the counterweight mechanism 50, the handle 71 is provided with a stopper D for limiting the retraction of the pull rope 72. The middle part of the second pivot arm 31-B is provided with a lock catch 90 and a fixing rope 91, and the fixing rope 91 extends from the lock catch 90 and sequentially passes through the adjusting pulley 76 and the second guide pulley 78 to be connected to the handle pulley block 70.
When the user uses the pulley assembly to exercise, the sleeve 73 is slidably positioned along the movable frame 20 to the appropriate position of the adjusting jack 20-1 by operating the adjusting pin 74. Because the adjusting pulley 76 is arranged in the pulley assembly, the pull rope 72 and the fixing rope 91 in the whole pulley assembly are always in a tight state, forming a labor-saving pulley block, which is more convenient for the user to exert force during exercise and improves the exercise effect.
In this embodiment, the first guide pulley 77 at the top of the movable frame 20 and the second guide pulley 78 at the top of the second pivot arm 31-B, which is far away from the pivot shaft 32, are connected by welding, which can make the connection between the two parts more firm. The pulley frame 79 at the top of the first pivot arm 31-A is connected by bolts, and there are three pulleys arranged side by side in the pulley frame 79, leaving a certain gap between the pulleys. In some embodiments, not shown, the guide pulley 77 and pulleys 75-1 and 75-2 can be made of rubber, plastic or other wear-resistant materials.
