TECHNICAL FIELD

[0002] This disclosure relates to weightlifting equipment for use with weight stand assemblies, more specifically weightlifting equipment with components and features configured to connect a rope-based weightlifting device to a conventional weight stand assembly. BACKGROUND

[0003] There are various types of strength training equipment that allow users to perform strength exercises in which the resistance element, providing the resistance for the exercise, moves in a controlled manner. In many cases, the equipment can change the direction of movement of the resistance element so that it differs from the direction of the force exerted by the user. For example, a machine might use a pulley and rope to redirect the movement of a resistance element so that it moves upward when a user pushes down on a handle, as with a lat pulldown machine. These types of equipment are often limited, restricting the number of exercises a user can perform, yet they can still occupy valuable space in a gym.This poses a significant problem for small gyms and home fitness studios where space may be extremely limited. Furthermore, a rope-based weightlifting device, whether configured as a standalone machine or as a component to attach to a barbell rack, requires a substantial financial investment and can present difficulties with shipping and assembly. Accordingly, there is a need for a weightlifting setup that incorporates this type of resistance element movement and can be integrated into an existing barbell rack structure, allowing users to perform multiple exercises in a reduced space, cost-effectively, and with simple installation.

In one embodiment, a single surface of a frame element 20 may have a mixture of different types of holes 26. It is understood that opposite holes 26 (i.e., directly opposite each other) may be axially aligned along the length of the frame element 20 and may have the same shapes. Alternatively, in some embodiments, the frame elements 20 may have an L-shaped or U-shaped structure with a plurality of holes 26 arranged along the length of each surface.This arrangement of the mounting holes 26 allows fasteners (not shown) to project into or through each frame member 20 in two transverse directions to attach various components to each side of each frame member 20, including weightlifting structures, other frame members 20, and other structures. Suitable fasteners include pins (including cotter pins or other locking pins), bolts and other threaded connectors, clamps, and other types of fasteners. The [details of the] Fig. The rack assembly 10 and the frame 12, constructed as shown in Figure 1 and described here, enable a modular design to provide a variety of desired configurations, including customizable sizes, layouts, and supported weightlifting structures. It is understood that the rack assembly 10 and the frame 12 are made of Fig. 1 are represented in a simple form, which can be larger and more complex, involving several weightlifting structures.

[0021] The various embodiments of weightlifting devices 30 disclosed herein can be configured for use with an existing weight rack assembly 10 by connecting them to typical and existing frame elements 20, as described herein and shown in the figures. The connection of the weightlifting devices to such a weight rack assembly 10 can be achieved without the use of special frame elements 20 or with minimal use of such special frame elements 20.

[0022] The weight storage device 10 in Fig. 1 can comprise a weightlifting device 30 for use with a resistance band 31 to provide resistance for a weightlifting exercise. The weightlifting device 30 generally comprises a fixed connection 32 that is fixedly attached to one of the frame elements 20, a movable connection 33, a handle attachment 34, a rope system 35 that connects the movable connection 33 to the handle attachment 34, a handle 36 that is connected to the handle attachment 34, and a pulley system 37 that guides the rope system 35.

[0023] As in Fig. As can be seen in Figure 1, the band 31 can in one embodiment be formed as a complete loop, so that two substantially parallel segments 31A, 31B extend between the fastening 40 and the connector 42 and are connected to each other at the ends 31C, 31D of the band 31.

[0024] The fixed connection 32 and the movable connection 33 are both attached to the resistance band 31, so that movement of the movable connection stretches the resistance band 31 to create resistance for the weightlifting exercise. The fixed connection 32 in Fig. 1 comprises a base 38, a base connector 39 (e.g., a removable and attachable pin) that firmly connects the base 38 to the frame element 20, and a fastener or connector 40 (e.g., a carabiner) that is connected to the base 38 to allow a removable attachment to the resistance band 31. The movable connection 33 in Fig. 1 comprises a base 41 connected to the rope system 35 and a connector 42 (e.g., a carabiner) connected to the base 41 to allow a detachable attachment to the resistance band 31. The fixed and / or detachable connection 32, 33 can be configured for free rotation, e.g., by means of internal bearings.

[0025] The handle attachment 34 can be connected to the rope system 35 and also attached to a handle 36 so that the user can grip it to perform the weightlifting exercise. The handle 36 in Fig. 1 is a lat pulldown handle configured for gripping with the user's hands, but other handles may be used in other embodiments. It is understood that the handle attachment 34 can also be connected to other user-engaging devices, such as a belt or harness. The handle attachment 34 may include a detachable connector for attachment to various handles 36 or other devices, such as a carabiner. The handle attachment 34 may be configured for free rotation, for example, by means of internal bearings.

[0026] The rope system 35 in Fig. 1 comprises a single rope 43, which is connected at one end to the movable connection 33 and at the other end to the handle attachment 34. In another embodiment, the rope system 35 may comprise multiple ropes 43. Additionally, the rope system 35 may include stops 44 to limit the movement of the rope(s) 43. The rope system 35 may be configured such that the rope(s) 43 passes through one or more of the frame elements 20, for example, through one or more mounting holes 26 and / or through the central passage of the frame element(s) 20. The rope 43 in Fig. 1 runs transversely to the frame element 20 (i.e., vertically through a horizontal frame element 20B) through one of the mounting holes 26, through the hollow interior of the horizontal frame element 20B, and exits through another mounting hole 26 on the opposite side of the lateral frame element 20B. In some embodiments, the mounting hole 26 on the top of the lateral frame element 20B and the mounting hole 26 on the bottom of the lateral frame element 20B may be aligned with each other. While the lower mounting hole 26 in Fig. The lower mounting hole 26 is not shown. Fig. Figure 33 shows a similar embodiment. Furthermore, a person skilled in the art would readily recognize its presence and location.

[0027] The pulley system 37 can comprise one or more pulleys 45 configured to guide and, in some cases, redirect the rope(s) 43 of the rope system 35. For example, the pulley system 37 can comprise a first pulley 45A attached at a first point on the frame 12 and a second pulley 45B attached at a second point on the frame spaced apart from the first pulley. The pulley system 37 in Fig. 1 comprises two pulleys 45 such that the rope 43 extends directly from the first pulley 45A to the second pulley 45B, with each pulley 45 redirecting the rope 43 as required. The pulley system 37 can engage with a resistance element that provides a resistance force opposing the movement of the rope. The resistance element can comprise a free weight such as a barbell, a resistance band, a machine, or a limited weight, and / or a combination of resistance elements or other similarly arranged elements. For example, in the embodiment of Fig. 1. The rope 43 is engaged with a resistance band 31 at the movable connection 33, so that a user can pull the handle 36 away from the front pulley 45A or pull the handle 36 vertically (or substantially vertically) downwards, thereby moving the rope 43, which causes a vertical upward movement of the movable connection 33, thereby stretching the resistance band 31. In another embodiment, the pulley system 37 can also be configured to provide a mechanical advantage in a weightlifting exercise, for example by incorporating pulleys and additional ropes 43, as shown in the Fig. 64-65 shown and described herein. The pulley system 37 also includes one or more brackets 46 configured to attach the pulley(s) 45 to the frame 12. In the embodiment according to Fig. 1 The pulley system 37 comprises a single bracket 46 which is detachably connected to a horizontal or lateral frame element 20B or a vertical frame element 20A by fasteners (not shown), such as pins (including cotter pins or other locking pins), bolts and other threaded connectors, clamps and other types of fasteners. The bracket 46 can rotatably support both pulleys 45 at opposite ends of the bracket 46, and the bracket 46 includes a central slot 47 which accommodates a portion of both pulleys 45.

[0028] The weightlifting device 30 can also include one or more protective devices 48 to protect the rope 43 from abrasion when passing through a frame element 20, as shown in Fig. Figure 33 shows the weightlifting device 30 in Fig. 1 comprises a guard 48 in the form of a grommet or socket that is received in one of the mounting holes 26 of the frame element 20, wherein the rope can extend through an opening 66 in the guard 48 to protect the rope 43 from abrasion during movement through the mounting hole. In one embodiment, the guard 48 may be made of a polymer material, such as rubber or another durable polymer, but in other embodiments it may also be made of other materials. The material of the guard 48 may have properties such as low friction and / or elasticity and may have edges that are rounded, chamfered, or otherwise configured to reduce abrasion. The weightlifting device 30 in Fig. 1 can comprise a second guard 48 which is received in the opposite mounting hole 26 on the underside of the frame element 20. In a further embodiment, the guard 48 can be in the form of a sleeve or other tubular structure extending through the frame element 20 and received in both mounting holes 26. In some embodiments, the guard 48 can have a groove 65 or other retaining device on an outer surface that engages in the wall of the frame element 20 to fasten the guard 48 to the frame element 20, as shown in Fig. Figure 33. It is understood that each embodiment of a weightlifting device described herein, in which a rope 43 passes through a frame element 20, may include one or more protective devices 48 as described herein, although protective devices 48 are not shown in connection with all embodiments.

[0029] The weightlifting device 30 in the embodiment of Fig. 1 is configured for use as a lat pulldown mechanism, however, it is understood that the weightlifting device 30 can be modified for use with other weightlifting exercises, for example by fitting a different handle, rearranging components and / or adding additional pulleys 45 to the pulley assembly 37.

[0030] The Fig. Figures 2-13 show another embodiment of a weightlifting device 30, which incorporates many features of the weightlifting device 30 from Fig. 1. The pulley bracket 46 in this embodiment comprises a mounting structure 49 with two lateral mounting plates 50 extending on opposite sides of each pulley 45, each lateral mounting plate being connected to opposite sides of the lateral frame element 20B to accommodate the lateral frame element 20B between them. The mounting structure 49 is connected to the frame element 20 by accommodating fastening elements 51 that are connected to both mounting plates 50 and extend through the frame element 20. The mounting plates 50 both extend outward at an angle to the bracket 46 and then vertically downward to connect to and engage with the lateral frame element 20B.In this configuration, a third or front mounting plate 52 is connected by fasteners 51 to an adjacent vertical frame element 20A to support the front of the bracket 46. The third mounting plate 52 is perpendicular to the mounting plates 50 in this configuration. The guard 48 can be positioned below the bracket 46 and between the mounting plates 50 in this configuration. Additionally, the front pulley 45A can be positioned in front of the front mounting plate 52, so that the front pulley 45A is completely outside the circumference of the frame 12, making it easier for a user to grip the handle 36. Fig. Figures 7-13 show additional views and illustrations of the weightlifting device 30. Fig. 2 and of the pulley system 37 and of the bracket 46 thereof. Fig. Figure 14 shows a view of the fixed connection 32, which is located along a second lateral frame element 20B.

[0031] The Fig. Figures 15-33 show a further embodiment of the weightlifting device 30, in which the pulley arrangement 37 comprises a front pulley 45A and a rear pulley 45B, wherein the rear pulley 45B can be positioned at several locations. For example, the Fig. 15-23 a pulley arrangement 37 in which the rear pulley is in a first position closer to the front pulley 45A, while the Fig. Figures 24-33 show the weightlifting device 30 with the rear pulley 45B in a second position, which has a greater distance from the front pulley 45A. This adjustable position of the rear pulley helps the weightlifting device 30 to accommodate frames 12 with different hole spacings and allows the weightlifting device 30 to be mounted on several weight stands 10.

[0032] The weightlifting device 30 can be used to convert an existing frame 12 into a functional weightlifting device. As explained above, the pulley assembly 37 can be connected to a first lateral frame member 20B of the frame 12. The pulley assembly 37 can comprise a pair of pulleys 45A, 45B. A first guard 48 can be attached in one of the holes on the top of the first lateral frame member 20B, and a second guard 48 can also be attached in one of the holes on the underside of the first lateral frame member 20B, aligned with the hole 26 on the top where the guard 48 is located.Next, a rope system 35 can be installed on the pulley, the rope 43 being able to engage with each pulley 45A, 45B in both vertical and horizontal orientations to guide the rope 43, the rope 43 extending through one of the holes 26 in a top surface of the first lateral frame element 20B and also through one or more openings 66 in one (or both) of the guards 48. A first end of the rope can be connected to a movable connection 33, while a second end of the rope 43 can be attached to a handle attachment 34. Next, the first end 31C of the resistance band 31 can be connected to a second lateral frame element 20B, spaced apart from the first lateral frame element 20B, using a fixed connection 32, and the opposite end 31D of the resistance band 31 can be connected to the movable connection 33.

[0033] The Fig. Figures 34-35 show further embodiments of a weightlifting device 30, which incorporate many of the features of the weightlifting devices 30 from the Fig. exhibiting 1-33. For the sake of brevity, these common features are not described in detail here, and it is understood that similar reference numbers can be used to refer to components of the Fig. 34-35 to refer to the components of the in Fig. embodiments shown in 1-33 are similar. Fig. 34-35 The movable connection 33, which is attached to the rope system 35, can be connected to a weight support 54, which supports a free weight in the form of a weight plate 53 for additional resistance. For example, in Fig. 34 The rope system 35 is connected to a weight support 54, which is configured to support one or more weight plates 53 such that the one or more weight plates 53 rest on the support plate 59 of the weight support 54. In addition, the weight support 54 can also be connected to a resistance band 31, so that the weight plate 53, the weight support 54 and the resistance band 31 provide the resistance for the weightlifting exercise. When a user moves the handle 36 away from the pulley 45, or moves the handle 36 vertically (or substantially vertically) or downwards, the movable link 33 and the weight support 54 move upwards away from the fixed link 33. Similarly, as the movable link 33 moves away from the fixed link 32, the resistance band 31 can be kept under tension and stretched as the handle 36 moves away from the pulley 45.In some embodiments, the resistance band 31 can be under tension when the stop 44 engages with the pulley 45 to stabilize the weight support 54. In another embodiment, which is described in . Fig. As shown in Figure 35, the movable connection 33, which is attached to the rope system 35, is connected to a weight support 54 to support a weight 53 without using the resistance band 31, so that the weight 53 and the weight support 54 provide the resistance for the weightlifting exercise.

[0034] The Fig. Figures 62-63 show another embodiment of a pulley arrangement 37 for a weightlifting device 30, which incorporates many of the features of the pulley arrangement 37 from the Fig. 15-33. For the sake of brevity, these common features are not described in detail here, and it is understood that similar reference numbers can be used to refer to components of the Fig. 62-63 to refer to the components of the in Fig. The embodiments shown in 15-33 are similar. In the embodiment of Fig. 62-63 the bracket 46 has connections for four different pulleys 45, and the pulley arrangement 37 in the Fig. 62-63 has four pulleys 45 connected to the bracket 46. This configuration can be used in more complex or cumbersome cable routing configurations. Additionally, in one embodiment, fewer than four pulleys 45 can be connected to the bracket 46, allowing for greater adaptability of the pulley arrangement 37.

[0035] The Fig. Figures 36-45 show another embodiment of a strength training machine 30, which incorporates many of the features of the strength training machines 30 from the Fig. exhibits 1-35. For the sake of brevity, these common features are not described in detail here, and it is understood that similar reference numbers can be used to refer to components of the Fig. 36-45 to refer to the components of the in the Fig. embodiments shown in 1-35 are similar.

[0036] The weightlifting machine 30 in the Fig. 36-45 can be configured for use with free weight plates 53 alone or in combination with a resistance band 31, similar to the embodiment of the Fig. 34 and Fig. 35. In this embodiment, the machine 30 comprises a weight support 54, which is similar to the weight support 54 in the Fig. 34 and Fig. The machine 30 is connected to the cable system 35 and has a base support 70 configured to hold the weight(s) 53 and the weight support 54 while the weight plates 53 are mounted on the support 54. The machine 30 also has a cable system 35 and a pulley system 37, which includes a bracket 46 and a fixed connection 32 for attaching the resistance band 31 to the frame assembly 10. The fixed connection 32 in this embodiment can include a fork head structure 63 for connecting to a lateral frame element 20B of the frame assembly 10 and a connecting hole 64 for connecting to the resistance band 31 (e.g., via a carabiner). It is understood that the machine 30 in the Fig. 36-45 can be configured for use in a vertical or downward-inclined pulling exercise, such as a lat pulldown or triceps extension, and that the rope system 35 can have a suitable handle connected to the handle attachment 34. It is also understood that the rope system 35 can be routed differently to configure the machine 30 for use in a different exercise with a different movement pattern.

[0037] The weight plate 54 is in the Fig. Figures 34-37, 40, 41 and 45 show the assembly and generally comprises a support plate 59 configured to support the weight plate(s) 53 from below in a rest position and during a lifting exercise, a shaft 60 extending upwards from the support plate 59, a first connection 61 at the upper end of the shaft 60 for connection to the rope system 35, and a second connection 62 below the support plate 59 for connection to a first end 31C of the resistance band 31. The connections 61, 62 in the Fig. 34-37, 40, 41 and 45 are manufactured using carabiners, and it is understood that both connections 61, 62 can be configured as detachable connections. The shaft 60 in the Fig. 34-37, 40, 41 and 45 can be a hollow tube extending through the support plate 59 and attached to the support plate 59 (e.g., by welding), such that portions of the shaft 60 are positioned above and below the support plate 59. The upper section of the shaft 60 can extend upward from the support plate 59 and be configured to extend through holes in the weight plate(s) 53 to attach the weight plate(s) 53 to the weight support 54. The connections 61, 62 are fixedly connected to the upper and lower ends of the shaft 60, respectively (e.g., by welding), and each connection 61, 62 extends across the hollow center of the shaft 60. It is understood that the weight support 54 may be configured differently in other embodiments, and the embodiment in the Fig. The 34-37 and 45 offer a durable and effective function with acceptable weight and simple construction.

[0038] The base support 70 in the Fig. 36, Fig. 37, Fig. 40 and Fig. 41 is in the Fig. 42-44 are shown individually in detail. The base support 70 generally has a fastening structure 71 for detachable connection with a vertical frame element 20A of the weight rack assembly 10 and a support element 72 configured to engage the weight support 54 and the weight plate(s) 53, supporting them in an elevated position. The base support 70 can be used during training to limit the range of motion, to support the weight support 54 between sets, or during the mounting of the weight plate(s) 53 onto the weight support 54. The weight support 54, as shown in the Fig. 34 and Fig. As shown in Figure 35, the weight plate(s) 53 must be disconnected from the rope system 35 to attach or remove them, leaving the weight support 54 and the weight plate(s) 53 unsupported. This complicates the installation of the weight plate(s) 53 and the reconnection of the weight support 54 to the rope system 35, as the user must bear the weight of both the support 54 and the weight plate(s) 53 for part or all of this process (and may also be subject to the additional resistance of the resistance band 31). The support element 72 of the base support 70 can extend into a path of movement of the weight support 54 defined by a range of motion of the rope 43, such that the support element 72 of the base support 70 is configured to engage with and support the weight support 54 in the raised position within the path of movement of the weight support 54.The base support 70 supports the weight support 54 in a position where the cable system 35 can be easily connected to and disconnected from the weight support 54. It also allows the weight plate(s) 53 to be mounted on the weight support 54 without disconnecting the weight support 54 from the resistance band 31. The mounting structure 71 can be configured to be attached at different heights along the length of the vertical frame element 20A, so that, depending on the configuration of the machine 30 and the cable system 35, a suitable height for mounting and dismounting the weight plate(s) 53 can be achieved. The base support 70 can also form a lower limit for the range of motion of the weight plate(s) 53 during training.

[0039] The fastening structure 71 of the base support 70 in the Fig. 36, 37 and 40-44 comprise two spaced mounting plates 73 connected to a base plate 74 and extending rearward from the base plate 74, so that the frame element 20A can be inserted between the mounting plates 73 and a fastening element 75 (e.g., a removable pin) through holes in the mounting plates 73 and holes 26 in the frame element 20A to fix the base support 70 in its position. The support element 72 of the base support 70 in the Fig. Figures 36, 37, and 40-44 can comprise two legs 76 extending forward from the base section 74 to define a space 77 between them, and a bridge plate 78 connected to the legs 76 and covering part of the space 77. In this embodiment, the legs 76 extend forward and are inclined away from each other, such that the space 77 is widest at the distal ends of the legs 76. Alternatively, in some embodiments, the legs 76 can extend forward substantially parallel to each other. The legs 76, as in the Fig. Figures 36, 37, and 40-44 show that the legs 76 are triangular in shape such that their heights are greatest near the base plate 74 and taper towards their distal ends. For example, each leg has a first height near the base section 74 and a second height near a distal end of each leg 76, the first height being greater than the second height. In one embodiment, the side surfaces of the legs 76 are formed by two plates 79 connected to the base plate 74 and extending outwards and forwards from it. In another embodiment, each of the plates 79 can be formed as an integral plate structure with one of the mounting plates 73 by means of an integral connection technique. Additionally, the bridge plate 78 and the tops of the legs 76 can also be formed together as a single plate element 80, which is bent downwards along the inner sides of the legs 76 to open the space 77.The base plate 74 can be a separate plate element or an integral part of the plate element 80 that forms the bridge plate 78 and the top and inner surfaces of the legs 76. These plate structures can be formed from metallic materials and joined together by welding and / or other joining techniques, and the plate elements can have some mechanical locking structures to support this connection.

[0040] In use, the weight support 54 sits on the support element 72, so that the underside of the support plate 59 rests on the legs 76 and optionally also on the bridge plate 78. The legs 76 are spaced apart at a distance less than the width of the support plate 59 to accommodate this support configuration. The components of the weight support 54 below the support plate 59, e.g., the lower end of the shaft 60 and the second connection 62, project into the space 77 between the legs 76 to allow a connection with the resistance band 31, which is held so that it extends through the space 77. In this configuration, the base plate 74 can engage with the vertical frame element 20A to counteract rotation of the base support 70 due to the weight exerted on the support element 72. It is understood that the base support 70 may have a different configuration in other embodiments.For example, in one embodiment the space 77 may be enclosed by the legs (e.g. a hole / an opening), and in another embodiment the space 77 may not be present, for example if the weight support 54 does not have a structure below the support plate 59 for connection with a resistance band 31.

[0041] The pulley system 37 in the Fig. 36-45 can include a bracket 46 connected to the frame 12 and having two pulleys 45 that engage with and guide the rope(s) 43. The pulley bracket 46 in this embodiment is in the Fig. 25-26 shown in more detail. The pulley bracket 46 in the Fig. 38 and Fig. 39 can comprise a mounting structure 49, which includes two mounting plates 50 extending on opposite sides of the frame element 20 to accommodate the frame element 20 between them. The mounting structure 49 is connected to the frame element 20 by accommodating fasteners 51 that are connected to both mounting plates 50 and extend through the frame element 20. The mounting plates 50 both extend outward at an angle to the bracket 46 and then vertically downward to connect to and engage with the frame element 20. The bracket 46 can also have wings 56 that extend outward and downward near the center of the bracket 46 to engage, in this configuration, an adjacent vertical frame element 20A by means of fasteners 51 to support the front of the bracket 46.In this configuration, the wings 56 are adjacent to the outwardly extending sections of the mounting plates 50. The vertical frame element 20A in the . Fig. 25-26 extends over the top of the horizontal frame element 20, and the body of the bracket 46 is mounted at the same level as the top of the vertical frame element 20A. In this configuration, the mounting plates 50 extend further downwards than the mounting plates 50 in the Fig. 1-35, so that a gap 57 is defined between the underside of the body of the bracket 46 and the top of the horizontal frame element 20. The bracket 46 further comprises one or more bracing elements 58 that engage in the top of the horizontal element 20 to stiffen and stabilize the bracket 46. The in Fig. The bracing elements shown in 38 have the form of rigid tabs that are bent inwards from the mounting plates 50.

[0042] In the embodiment of the Fig. 36-45 The bracket 46 is connected to a horizontal or lateral frame element 20B by fasteners 51 such as pins (including cotter pins or other locking pins), bolts and other threaded connectors, clamps and other types of fasteners. The bracket 46 supports both pulleys 45 at opposite ends of the bracket 46, and the bracket 46 includes a central slot 47 that accommodates a portion of both pulleys 45.

[0043] With reference to Fig. Figure 46 shows an embodiment of a weight storage device 10 comprising a frame 12 and one or more weightlifting structures connected to and / or supported by the frame 12, including one or more racks, barbell stands and bodyweight exercise supports (e.g. bars, handles and other structures for use in bodyweight exercises such as pull-ups, climbing and others) as well as weightlifting accessories and mechanisms. Fig. Figures 46-48 illustrate further embodiments of a weightlifting device 30, which incorporate many of the features of the weightlifting devices 30 from the Fig. exhibiting 1-45. For the sake of brevity, these common characteristics are not described in detail here, and it is understood that similar reference numbers can be used to refer to components of the Fig. 46-48 to refer to the components of the in Fig. The embodiments shown in Figures 1-45 are similar. The frame 12 in this embodiment is primarily formed by a plurality of structural support elements or frame elements 20 in the form of metal rods, which can be arranged and connected to one another as vertical beams, horizontal or lateral crossbeams, and angle beams to support the various structures of the frame assembly 10, as shown above in the figures. Fig. The embodiments shown in 1-45 are described.

[0044] The frame assembly 10 in Fig. 46 includes a weightlifting machine 30 which includes a movable weight plate assembly 90 configured for installation on an existing rack assembly 10 for use in a weightlifting exercise. Fig. Figure 47 shows part of a frame assembly 10 with a weightlifting machine 30, which is similar to those in Fig. 46 and is similar to those described above in the previous embodiments, and Fig. 48 and Fig. Figure 49 shows additional embodiments of frame assemblies 10 with weightlifting machines 30 with components that are related to the one described here in relation to Fig. 46 and Fig. The components described in section 47 are similar. The weightlifting device 30 generally comprises a weight engagement element 92 configured to selectively engage one or more weights 94, a handle attachment 34, a rope system 35 connecting the weight engagement element 92 to the handle attachment 34, a handle 36 connected to the handle attachment 34, and a pulley system 37 guiding the rope system 35.

[0045] The weight engagement element 92 in this embodiment comprises an elongated element extending through aligned holes (not shown) in a plurality of stacked weights 94. The weight engagement element 92 may be firmly connected to one or more of the upper weights 94 in the stack, or to none of the weights 94, and several of the lower weights 94 in the stack may not be firmly engaged with the weight engagement element 92.
