Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a training rack. Background Technology

[0002] With the improvement of people's living standards, the demand for self-fitness and exercise is increasing. To better facilitate daily exercise, many communities and even individual households install or purchase appropriate sports equipment, with training racks being the most common type. However, most common indoor and outdoor training racks are simple structures, only suitable for basic stretching or exercises, and their functions are limited, failing to adequately meet the exercise needs of the public. Furthermore, the target audience for training racks on the market is relatively narrow, generally requiring a certain level of fitness level before use. This is particularly unfriendly to beginners, especially children, teenagers, and women. Because training racks need to withstand significant irregular forces, most are made of metal (aluminum alloy or steel). While metal materials offer excellent mechanical properties, they conduct heat quickly, making them feel cold to the touch, especially in cold weather, which is unfriendly to children and women. Therefore, this utility model was developed. Utility Model Content

DETAILED DESCRIPTION

[0036] To make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0037] Referring to Figures 1 to 10 The training rack of the utility model embodiment mainly comprises a frame body 10, a double bar 20, a single bar 30, at least two movable plates 40 and at least one free cross rod 50. The training rack of the utility model embodiment combines the functions of the rib frame, the single bar 30 and the double bar 20. It is various in function, simple and stable in structure.

[0038] Specifically, as Figure 1 and Figure 2As shown, the frame 10 includes a base frame 11, an upper frame 12, and two diagonal braces 13. More specifically, the base frame 11 is a square frame body 10, including two opposing and parallel horizontal frames 111 and two opposing and parallel horizontal bars 112. The two horizontal frames 111 and the two horizontal bars 112 are arranged in a quadrilateral, with the two horizontal bars 112 positioned above the two horizontal frames 111. Both ends of the two horizontal frames 111 partially extend to the outside of the horizontal bars 112, i.e., the outside of the aforementioned quadrilateral, and both ends of the two horizontal bars 112 also partially extend to the outside of the horizontal frames 111, i.e., the outside of the aforementioned quadrilateral. The upper frame 12 and the base frame 11 are arranged intersectingly (preferably perpendicular in the figure), i.e., the upper frame 12 and the base frame 11 are arranged in an L-shape. Specifically, the upper frame 12 includes two opposing and parallel vertical frames 121, with a second clearance space defined between the two vertical frames 121 to allow the user to move freely without interference. Two diagonal braces 13 are arranged obliquely between the upper frame 12 and the lower frame 11. Specifically, one end of each diagonal brace 13 is fixed at a position slightly above the middle of the vertical frame 121 on its corresponding side, and the other end is fixed at a position away from the upper frame 12 on its corresponding side. That is, each diagonal brace 13 and its corresponding horizontal frame 111 and vertical frame 121 form a triangle (exemplarily a right triangle in the figure; for ease of description and distinction, the right triangle here is described as the first right triangle). The two diagonal braces 13 are arranged opposite each other and parallel, with a first clearance space between them. As above, the first clearance space allows the user to move freely without interference when using the training frame. The angle between each diagonal brace 13 and its corresponding horizontal frame 111, i.e., the angle with the horizontal plane, is not particularly limited, for example, 60°. The arrangement of the diagonal braces 13 can stabilize the angle between the upper frame 12 and the lower frame 11. For the two horizontal bars 112, as Figure 2 As shown, it is a cylindrical rod, one of which is a transverse rod 112, i.e. Figure 2 The left front transverse bar 112 shown is located on the outside of the end where the transverse frame 111 connects to the diagonal brace 13, and the other transverse bar 112 is also as shown. Figure 2 The horizontal bar 112 at the right rear end, as shown, is located on the outer side of the end where the horizontal frame 111 connects to the vertical frame 121. Specifically, as... Figure 2 The two ends of the left front transverse bar 112 shown are fixedly connected to the two transverse frames 111 and the two diagonal braces 13 respectively (that is, the transverse bar 112 is fixed to the outside of the end where the diagonal brace 13 is connected to the bottom frame 11; for ease of description, this transverse bar 112 will be referred to as the first transverse bar). Figure 2The two ends of the right rear end transverse rod 112 are fixedly connected with the two transverse frames 111 and the two vertical frames 121 respectively (that is, the transverse rod 112 is fixed outside the end of the upper frame 12 and the bottom frame 11, for the convenience of description, the transverse rod 112 will be described as the second transverse rod in the following). More specifically, the first transverse rod is connected and fixed between any end of the first transverse rod and the connection between the corresponding inclined support 13 and the transverse frame 111 through the first connecting assembly 60. Similarly, any end of the second transverse rod is also connected and fixed between the corresponding transverse frame 111 and the vertical frame 121 through the first connecting assembly 60. Further preferably, the first reinforcing member 80 is arranged between the inclined support 13 and the transverse rod 112 connected thereto, and the second reinforcing member 90 is arranged between the vertical frame 121 and the transverse rod 112 connected thereto. Specifically, as shown in Figure 2 As shown, any end of the transverse rod 112 fixed outside the end of the inclined support 13 and the bottom frame 11 is arranged with a triangular first reinforcing member 80 at the corresponding end of the inclined support 13, and the upper end of any first reinforcing member 80 is fixed with the inclined support 13 and the lower end is inclinedly extended to the two sides and fixed with the end of the transverse rod 112 fixed outside the end of the inclined support 13 and the bottom frame 11, that is, the first reinforcing member 80 has two edges arranged at an angle such as 90°. As shown in Figure 2 As shown, the second reinforcing member 90 has the same structure as the first reinforcing member 80 Figure 2 The part of the second reinforcing member 90 is blocked in the middle view angle. The upper end of the second reinforcing member 90 is fixed with the corresponding vertical frame 121 and the lower end is fixed with the corresponding transverse rod 112, and the second reinforcing member 90 and the corresponding transverse frame 111 and vertical frame 121 form a right triangle (the right triangle here is described as the third right triangle, and the area is smaller than the second right triangle, and the specific area is not described and limited). The fixing between the first reinforcing member 80 and the inclined support 13 and the transverse rod 112, and the second reinforcing member 90 and the vertical frame 121 and the transverse rod 112 can be screws or rivets. The triangular reinforcing member can further increase the connection stability of the connection. For the two transverse frames 111 and the two vertical frames 121, they are rectangular plate blocks with square cross sections. For the two transverse rods 112, that is, the first transverse rod and the second transverse rod, they are cylindrical rod members with circular cross sections. As a replaceable embodiment of the bottom frame 11, as shown in Figure 3 As shown, the transverse rod 112 is a square rod, in this embodiment, the transverse rod 112 and the transverse frame 111 can be directly fixed and connected through fasteners such as long screws, and do not need to be connected through the first connecting assembly 60, that is, the horse clamp 120 or the U-shaped clamping member or the binding clamp, and the first reinforcing member 80 can be optionally arranged at the connection between the transverse rod 112 and the inclined support 13, and the second reinforcing member 90 can be optionally arranged at the connection between the transverse rod 112 and the vertical frame 121.

[0039] As Figure 2 shown, the double bar 20 includes two opposite and parallel spaced horizontal short bars 21, the two horizontal short bars 21 are connected at the inner side of the two inclined braces 13 and the two vertical frames 121 respectively, in the embodiment of the utility model, the two ends of the horizontal short bar 21 are not fixed, but can be moved at will. Any horizontal short bar 21 is arranged in parallel with the bottom frame 11 and perpendicular to the upper frame 12. Any horizontal short bar 21 divides the first right angle into a smaller triangle (exemplarily shown as a right triangle in the drawing, for the convenience of description and distinction, the right triangle here is a second right triangle), and a trapezoid (exemplarily shown as a right trapezoid in the drawing), the second right triangle is similar to the first right triangle, and the area ratio is not specially described and limited, such as 1:16. Both ends of any horizontal short bar 21 are partially extended and protruded outward, that is, as Figure 2 shown, the left front end of the horizontal short bar 21 is extended to the outer side of the inclined brace 13, that is, the left front side, and the right rear end of the horizontal short bar 21 is extended to the outer side of the vertical frame 121, that is, the right rear side, the part extended to the outer side is for the user to use the double bar 20 for double bar 20 training, and does not interfere with the inclined brace 13 or the upper frame 12 during the double bar 20 training. For the connection mode between any horizontal short bar 21 and the inclined brace 13 and the vertical frame 121, specifically, as Figure 2 shown, the inner side of each inclined brace 13 and the vertical frame 121 connected therewith is respectively provided with a U-shaped clamp or a horse clamp or a saddle clamp 120 (as Figure 10 shown), and the horizontal short bar 21 is horizontally arranged in the U-shaped clamp or the horse clamp 120 (as Figure 10 shown) or the saddle clamp on the corresponding inclined brace 13 and the vertical frame 121 and is fixed. Preferably, in order to prevent the free cross bar 50 or the horizontal short bar 21 from rotating at will when being fixed by, for example, the horse clamp 120. In the embodiment of the utility model, preferably, as Figure 10 shown, one or more pin holes 1201 (exemplarily one pin hole 1201) for fixing the pin 140 are formed on the horse clamp 120. Correspondingly, pin holes (not shown) for fixing the pin 140 are also formed on the free cross bar 50 and the horizontal short bar 21, when it is needed to remove the free cross bar 50 or move the position of the horizontal short bar 21, the pin 140 can be taken out; when it is needed to fix the horizontal short bar 21 or the free cross bar 50, the pin 140 can be inserted into the corresponding pin hole 1201 of the horizontal short bar 21 or the free cross bar 50 and the horse clamp 120. Figure 10

[0040] For the single bar 30, as Figure 2 ​As shown, the single bar 30 is horizontally arranged at the top end of the two vertical frames 121 and partially extends to the outside of the vertical frames 121 at both ends. For the fixation of the single bar 30 and the two vertical frames 121, as shown in Figure 2 As shown, the connection between the first transverse bar and the inclined support 13 and the transverse frame 111 and the connection between the second transverse bar and the transverse frame 111 and the vertical frame 121 are the same as the connection between the single bar 30 and the corresponding vertical frame 121 at either end of the single bar 30. Further preferably, a third reinforcing member 100 in a triangular shape is arranged between either end of the single bar 30 and the corresponding vertical frame 121. The third reinforcing member 100, like the first reinforcing member 80, includes two edges at an angle, for example, 90°. The third reinforcing member 100 is fixedly connected to the vertical frame 121 and the single bar 30 by screws or rivets.

[0041] As shown in Figure 1 , Figure 2 and Figures 4 to 6 , the utility model embodiment preferably includes three movable plates 40, the width of which is not limited and the length of which is greater than the distance between the two transverse frames 111. The placement position of the movable plates 40 is different in different states. Specifically, as shown in Figure 1 and Figure 5 , the three movable plates 40 are horizontally placed side by side on the upper surface of the bottom frame 11 in the initial state (i.e. the state when leaving the factory), and can serve as a support and heightening when a user, for example, a child, uses the double bar 20 for double bar training, i.e. the first use state. Of course, when an adult or a child with a higher height uses the double bar 20 for double bar training, the movable plates 40 can be taken down and directly placed on the bottom surface. In the second use state, as shown in Figure 4 , all or part of the movable plates 40 are placed on the two inclined supports 13, the user can place a free crossbar 50 on the double bar 20, and place a free crossbar 50 on the two vertical frames 121 and below the double bar 20, then sit on the free crossbar 50 on the double bar 20, hook the soles of the feet below the free crossbar 50 on the two vertical frames 121, and then lean back so that the back is against the movable plate 40 on the inclined support 13 to perform a high-difficulty sit-up. In the third use state, as shown in Figure 6 , one of the movable plates 40 is vertically placed at the connection between the two inclined supports 13 and the two vertical frames 121, and the remaining movable plates 40 are still placed on the bottom frame 11, then the user holds the single bar 30 with the back against the movable plate 40 to perform a hanging knee-up training, which exercises the abdominal muscles, the iliopsoas muscle, the rectus femoris muscle, etc., which is the basic function of the ribbed frame.

[0042] For the support 110, the support 110 of the utility model embodiment is exemplarily a horse riding card 120 as shown in the figure. Figure 10 As an alternative embodiment, the support 110 can also be other components such as a conventional binding or U-shaped or L-shaped hook on the market, as long as it can achieve the purpose of placing the free crossbar 50 when not in use and freely removing it when in use. The number of supports 110 is not particularly limited and can be set according to the number of free crossbars 50. The supports 110 can be arranged at intervals along the height direction of the vertical frame 121 on the left side and / or the right side of the vertical frame 121 as shown in the figure, and can also be arranged on the inclined support 13. Figure 2

[0043] The number of free crossbars 50 is not particularly limited and can be one, two, three, etc. The utility model is exemplarily two. As shown in the second use state. Figure 5 The free crossbar 50 of the utility model embodiment can be placed horizontally on the upper frame 12 through the support 110 arranged on the two vertical frames 121. For the free crossbar 50 which is a cylindrical rod with a circular cross section and has a length greater than the distance between the two vertical frames 121, the distance between the two horizontal short rods 21, and the distance between the two inclined supports 13. When the free crossbar 50 is placed on the double bar assembly, the support 110 can not be arranged on the double bar assembly, and the inclined support 13 and the vertical frame 121 can be used to limit the movement of the free crossbar 50. When the free crossbar 50 is placed on the inclined support 13, the corresponding support 110 needs to be arranged on the inclined support 13. In order to realize the adjustability of the position of the free crossbar 50, one support 110 can be arranged at intervals on the vertical frame 121 and the inclined support 13. The interval distance is not limited. Exemplarily, one free crossbar 50 is placed horizontally on the inclined support 13 and is wrapped with a soft pad, and one free crossbar 50 is placed horizontally on the upper and lower ends of the vertical frame 121. The user can support his feet on the free crossbar 50 on the vertical frame 121, hook his feet on the horizontal rod 112 fixed to the outer side of one end of the connection between the upper frame 12 and the bottom frame 11, press his abdomen on the free crossbar 50 on the inclined support 13, and perform a back stretching exercise with a barbell.

[0044] ​The training frame of the embodiment of the utility model, in addition to the use state above, still has other use states, for example, the user can also lie on the movable plate 40 on the bottom frame 11, the double feet back leans below the free crossbar 50 at the bottom end of the two vertical frames 121 and the double feet soles hook on the transverse rod 112 fixed on the one end outside of the connection of the upper frame 12 and the bottom frame 11 to carry out the back stretching training of the back bending upwards, can also place sandbags on the movable plate 40 on the bottom frame 11, use the double shoulders to carry the parallel bars 20 to carry out the weight-bearing deep squat exercise of the quadriceps femoris and gluteus maximus, can also carry out the training of one foot lifting and placing on the free crossbar 50 placed in the upper part of the upper frame 12, one foot hooking the horizontal bar 30, lower waist training of one foot supporting on the bottom surface, training of the rotatory force muscle group of one hand or both hands grabbing the free crossbar 50 placed on the parallel bars 20, footstep supporting on the transverse rod 112 fixed on one end outside of the connection of the inclined support 13 and the transverse frame 111 and the body tilting, push-up training of different difficulty of the double hands supporting on the inclined support 13 at different height positions and the like, the utility model does not enumerate one by one. When using, the population that cannot do the push-up can first do the inclined support 13 of different height, slowly strengthens the strength. Let the population that cannot do the pull-up first do the inclined pull of different height, slowly establishes the basic skill. Both functions can gradually increase the difficulty from simple to difficult, let the novice grow slowly. Then when the level is good enough, can also do the parallel bars 20 arm-bending support, the pull-up, the high-difficulty action of the suspension leg lifting on the rib wood frame. The base can do the leg-pressing type back stretching, exercises the rear chain muscle group. Can also do the supine leg lifting, practices the core muscle group such as abdominal muscle, iliopsoas and rectus femoris. The function is various, can let the weak group in strength use easily.

[0045] For the material of the frame body 10 (including the upper frame 12, the bottom frame 11 and the inclined support 13), the parallel bars 20, the horizontal bar 30, the movable plate 40 and the free crossbar 50, the utility model preferably is one of wood, carbon fiber or bamboo fiber. The problem of ice-cold touch in winter caused by metal material in the prior art is solved. The size of the transverse frame 111, the transverse rod 112, the vertical frame 121, the inclined support 13, the horizontal short rod 21, the horizontal bar 30, the movable plate 40 and the free crossbar 50 is not described and limited, and the person skilled in the art can select and design according to the actual demand.

[0046] Because wood, carbon fiber, and bamboo fiber are oriented fiber materials, their mechanical properties are inferior to those of metal materials, making the joints more fragile and prone to cracking. To solve this problem, this utility model innovatively adopts a cross-connection method and adds a first connecting piece 61 made of metal at the joint. Simultaneously, it uses a wire-wrapping method on the outer surface to reduce cracking while increasing strength. Specifically, a metal connecting piece is provided at the joints between the two ends of the first horizontal bar and the corresponding diagonal brace 13 and horizontal frame 111, the two ends of the second horizontal bar and the corresponding horizontal frame 111 and vertical frame 121, the two ends of the single bar 30 and the corresponding vertical frame 121, and the joint between the top of the diagonal brace 13 and the corresponding vertical frame 121, and these are all connected and fixed by connectors. However, regarding the connection structure between the top of the diagonal brace 13 and the vertical frame 121, since the connection point between the top of the diagonal brace 13 and the vertical frame 121 is a apex corner of the top of the diagonal brace 13 rather than a surface, the connection structure between the diagonal brace 13 and the vertical frame 121 is different from the connection structures of other joints. For ease of distinction, the connection structure at the junction of the top of any diagonal brace 13 and the corresponding vertical frame 121 is described as the second connection assembly 70. More specifically, as... Figure 2 , Figure 8 and Figure 10 As shown, the first connection component 60 includes, as Figure 9 The shown are saddle clamps, 120 or zip ties or U-shaped clamps, such as... Figure 7 The first connecting piece 61 and the first connecting member (not shown) are shown. Figure 2 , Figure 4 and Figure 9 As shown, the second connection component 70 includes, as Figure 8 The second connecting piece 71, the second connecting member 72, and the third connecting member 73 are shown. The main difference between the first connecting assembly 60 and the second connecting assembly 70 is that the structures of the first connecting piece 61 and the second connecting piece 71 are different, with the third connecting member 73 being longer than the second connecting member 72. The first connecting member, the second connecting member 72, and the third connecting member 73 are exemplarily screws of different lengths and / or thicknesses. The structure of the saddle clip 120, clamp, or U-shaped clamp of the first connecting assembly 60 is consistent with the structure of the saddle clip 120, clamp, or U-shaped clamp between the horizontal short bar 21 and the diagonal brace 13 and the vertical frame 121. The first connecting piece 61 and the second connecting piece 71 are both placed between the mating surfaces of the two connecting parts, and the saddle clip 120, clamp, or U-shaped clamp is located outside the outer connecting parts (such as the first horizontal bar, the second horizontal bar, and the single bar 30). More specifically, as shown... Figure 8As shown, the first connecting piece 61 is a square or diamond-shaped steel sheet, a through hole (not shown) is formed in the middle of the square or diamond-shaped steel sheet, and four first connecting holes 62 are arranged around the through hole and on both sides of two opposite diagonal lines of the square or diamond-shaped steel sheet. In order to facilitate description and distinction, the connecting holes are described as first connecting holes 62. Four first connecting holes 62 are arranged on the periphery of the four first connecting holes 62 and close to the four corners. A connecting hole (for the sake of description and distinction, the connecting hole is described as a second connecting hole 63) is formed close to each of the four corners. Two first connecting holes 62 on one diagonal line are used for connecting the U-shaped clamping piece or the horse clamping piece 120 to the first connecting piece 61 (for example, the two ends of the U-shaped clamping piece or the horse clamping piece 120 are linear and threaded, and are respectively arranged in the first connecting holes 62 on one diagonal line and are screwed with the threaded holes formed on one of the components). One group of the second connecting holes 63 on the two diagonal lines is used for connecting the first connecting piece to one of the components (for example, the diagonal brace 13, the horizontal frame 111 or the vertical frame 121), and the other group of the second connecting holes 63 is used for connecting the first connecting piece to the other component (for example, the diagonal brace 13, the horizontal frame 111 or the vertical frame 121). Therefore, the first connecting piece of the embodiment of the utility model actually includes at least two types of screws, one type of relatively thick screw is used for connecting the first connecting hole 62, and the other type of relatively thin screw is used for connecting the second connecting hole 63. As shown in Figure 4 and Figure 9 The second connecting piece 72 includes two first parts 711 and second parts 712 at an included angle (not limited, for example, 120°), and the first parts 711 and the second parts 712 are substantially triangular and are bent from the same sheet metal. One first fixing hole 713 is formed at the end of the first part 711 and the second part 712 away from each other, and two second fixing holes 714 are formed at the connection of the first part 711 and the second part 712 and are arranged in opposite directions and symmetrically. In the figure, the diameter of the second fixing hole 714 is larger than the diameter of the first fixing hole 713. The number of the second connecting piece 72 is two, the first part 711 is installed to abut against one of the side of the vertical frame 121 facing the diagonal brace 13 or the top end bottom surface of the diagonal brace 13 (for example, the side of the vertical frame 121 facing the diagonal brace 13 in the embodiment of the utility model as shown in Figure 4 ), and is fixed by the first fixing hole 713 of the second connecting piece 72 arranged in the first fixing hole 713. The second part 712 is installed to abut against the other of the side of the vertical frame 121 facing the diagonal brace 13 or the top end bottom surface of the diagonal brace 13 (for example, the side of the vertical frame 121 facing the diagonal brace 13 in the embodiment of the utility model as shown in Figure 4The top end of the exemplary inclined support 13 is fixed in the first fixing hole 713 provided on the bottom surface of the top end of the inclined support 13 and is fixed through another second connecting piece 72. The number of the third connecting pieces 73 is two, and the two third connecting pieces 73 are fixed to the inclined support 13 after sequentially penetrating the vertical frame 121, the second fixing hole 714 on the second connecting piece 71, and the side surface of the inclined support 13 away from the vertical frame 121, so as to realize the fixing of the inclined support 13 and the vertical frame 121. This connection mode resists the force of the vertical frame 121 shaking forward and backward, cooperates with the subsequent wire winding to jointly ensure the stability of the structure, and the vertical frame 121 and the inclined support 13 can be firmly fixed whether they are subjected to the force of mutual extrusion or the force of mutual separation. It should be noted that the connection between the top end of any inclined support 13 and the corresponding vertical frame 121 has a certain gap, and the gap (which is not described and limited in detail) should allow the horizontal rod 50 to be horizontally placed (as shown in Figure 6 The figure shows that the horizontal rod 50 can be used as a single bar 30, and the movable plate 40 can be vertically placed (as shown in Figure 7 The figure shows that the horizontal rod 50 can be used as a single bar 30, and the movable plate 40 can be vertically placed (as shown in Figure 4 The figure shows that the horizontal rod 50 can be used as a single bar 30, and the movable plate 40 can be vertically placed (as shown in
