Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and in particular to a modular fitness bar based on a dormitory bed frame. Background Technology

[0002] Indoor exercise provides great convenience for students' fitness, and the horizontal bar is an essential piece of equipment. Wall-mounted horizontal bars require a sturdy solid wall that allows drilling or a reliable door frame. However, many dormitory beds are bunk beds surrounded by modular furniture or glass windows, making it difficult to find a suitable and safe installation location. Sometimes, the protruding bar can obstruct passage and movement within the dormitory, making it unsuitable for use in student dormitories. On the other hand, some schools have equipped students with beds that come with built-in fitness functions and horizontal bars. However, most beds are still traditional beds without fitness functions, meaning that most students still cannot conveniently exercise with the help of a horizontal bar in their dormitories. Summary of the Invention

[0003] To address the shortcomings of the current invention, this invention provides a modular fitness bar based on a dormitory bed frame, which can be flexibly installed on a bed frame or ladder, allowing for diverse installation scenarios.

[0004] According to an embodiment of the present invention, a modular fitness bar based on a dormitory bed frame includes: a bar body, the bar body including a sleeve and an adjusting rod, the two sides of the sleeve being screwed to one end of the adjusting rod, and further including: a second support frame, a first fixed support part, a second fixed support part, and a connecting sleeve, the end of the adjusting rod away from the sleeve being sleeved into a first interface of the first fixed support part and detachably connected by a small bolt, the connecting sleeve being sleeved on the adjusting rod, the connecting sleeve being hinged to one end of the second support frame, and the other end of the second support frame being hinged to the second fixed support part.

[0005] According to the invention, the modular fitness bar based on the dormitory bed frame can be installed around different positions of the bed frame by changing the position and angle of the fixed support and the second support frame, and different structures can be produced to achieve the same effect. There is no need to go to the gym, and you can pull up the bar anytime and anywhere, realizing the integration of exercise equipment into the dormitory.

[0006] In some embodiments of the present invention, the connecting sleeve is provided with a threaded hole, and a large screw is screwed into the threaded hole. When the large screw is tightened, it can abut against the adjusting rod, so that the horizontal position of the connecting sleeve can be adjusted arbitrarily. It can be used to adjust the angle and position of the second support frame to adapt to different bed frame and bed ladder installation scenarios.

[0007] In some embodiments of the present invention, the first fixed support part is composed of a first frame and a second frame. The first frame and the second frame are connected and form a circular mounting cavity in the middle. The two sides are detachably connected by fixing bolts and fastened to the bed frame or bed ladder. The first frame and the second frame are used for the selected mounting position of the bed frame or bed ladder, and the fixed position can be arbitrarily selected.

[0008] In some embodiments of the present invention, the circular threaded hole provided on the second bracket connecting seat and the circular threaded hole provided on the end of the bar body are detachably connected by a small screw.

[0009] In some embodiments of the present invention, the circular threaded hole provided on the second frame connecting seat corresponds to the circular threaded hole provided on the end of the bar body, and there are two such holes, which correspond to the horizontal bar and vertical bar of the dormitory bed frame or bed ladder respectively.

[0010] In some embodiments of the present invention, the second fixed support portion includes a fixed support portion connecting seat, and the second support frame end connecting seat cooperates with the fixed support portion connecting seat and is fixed by a second adjusting bolt.

[0011] In some embodiments of the present invention, the two ends of the sleeve and one end of the adjusting rod are provided with threaded lines, and the two ends inside the sleeve are connected to the adjusting rod along the spiral line to realize fine adjustment of the horizontal distance of the single bar.

[0012] In some embodiments of the present invention, the helixes at both ends inside the sleeve are greater than the helixes at one end of the adjusting rod.

[0013] By adjusting the installation position of the fixed support and the angle and position of the second support rod, the installation position of the bed frame or bed ladder can be flexibly changed. The installation position is basically centered around the bed frame, and different structures can be designed to achieve the same effect.

[0014] The advantages of this invention compared to the prior art are: By changing the position and angle of the fixed support and the second support frame, it can be installed around different positions of the bed frame to create different structures and achieve the same effect. There is no need to go to the gym; you can pull up a horizontal bar anytime, anywhere. This brings exercise equipment into the dormitory. It is more suitable for dormitory use than wall-mounted horizontal bars. The equipment is simple, and if you don't consider the extension of the horizontal bar distance, the cost is about the same as a regular horizontal bar. It is basically designed to fit around the bed frame. Attached Figure Description

Detailed Implementation

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] A modular fitness bar based on a dormitory bed frame according to an embodiment of the present invention, such as... Figure 1 and Figure 2 As shown, it includes: a lever body 100, which includes a sleeve 1 and an adjusting rod 3. The two sides of the sleeve 1 are screwed to one end of the adjusting rod 3. It also includes: a second support frame 6, a first fixed support part 4, a second fixed support part 5, and a connecting sleeve 7. The end of the adjusting rod 3 away from the sleeve is fitted into the first interface 422 of the first fixed support part 4 and is detachably connected by a small bolt 421. The connecting sleeve 7 is fitted on the adjusting rod 3. The connecting sleeve 7 is hinged to one end of the second support frame 6, and the other end of the second support frame 6 is hinged to the second fixed support part 5.

[0019] According to the present invention, the modular fitness bar based on a dormitory bed frame can be installed around different positions of the first fixed support part 4, the second fixed support part 5, and the second support frame 6 by changing their positions. Different structures can be produced to achieve the same effect. There is no need to go to the gym, and the bar can be used anytime and anywhere, realizing the integration of exercise equipment into the dormitory.

[0020] In some embodiments of the present invention, such as Figure 3As shown, the connecting sleeve 7 is provided with a threaded hole, and a large screw 11 is screwed into the threaded hole. When the large screw 11 is tightened, it can abut against the adjusting rod 3, so that the horizontal position of the connecting sleeve 7 can be adjusted arbitrarily. The large screw 11 tightly abuts against the adjusting rod to prevent the fixed sleeve from sliding. It can also be used to adjust the angle and position of the second support frame to adapt to different bed frame and bed ladder installation scenarios. Therefore, the structure is simple and easy to implement. In the description of the present invention, "multiple" means two or more.

[0021] In practical applications, for example, the connecting sleeve 7 and the adjusting rod 3 are connected by a large screw 11, thereby adjusting the position of the second support frame 6, and the connection strength is relatively high. Of course, the distance between the connecting sleeve 7 and the adjusting rod 3 can also be adjusted in other ways, and the present invention does not limit this.

[0022] In some embodiments of the present invention, such as Figure 2 As shown, the first fixed support part 4 is composed of a first frame 41 and a second frame 42. The first frame 41 and the second frame 42 are connected and form a circular mounting cavity in the middle. The two sides are detachably connected by fixing bolts 43 and fastened to the bed frame or bed ladder.

[0023] In some embodiments of the present invention, such as Figure 2 As shown, the circular threaded hole on the connecting seat of the second frame 42 mates with the circular threaded hole on the end of the rod body 100, and is detachably connected by a small screw 421. The first and second frames are used for the vertical rod section of a selected bed frame or bed ladder, and can be fixed at any selected height, such as... Figure 4 As shown, in another embodiment of the first fixed support part 4 of the single bar, the end of the adjusting rod 3 away from the sleeve is inserted into the second interface 423 of the first fixed support part 4 and is detachably connected by a small bolt 421. The circular threaded hole of the connecting seat of the second sleeve 42 is connected to the circular threaded hole at the end of the bar body 100 and is detachably connected by a small screw 421. The first fixed support part 4 can be sleeved on the crossbar of the bed frame, so that the installation range of the single bar is larger. When using it, the customer can choose the position that satisfies him / her according to his / her installation needs.

[0024] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the circular threaded hole provided on the connecting seat of the second frame 42 corresponds to the circular threaded hole provided on the end of the bar body 100, and there are two such holes, which correspond to the two installation methods of the horizontal bar and vertical bar of the dormitory bed frame or bed ladder, respectively.

[0025] In some embodiments of the present invention, the second fixed support part 5 includes a fixed support part connecting seat 51, and the end connecting seat of the second support frame 6 cooperates with the fixed support part connecting seat 51 and is fixed by the second adjusting bolt 13.

[0026] The single bar is easy to install and disassemble. When the single bar is not in use, it can be partially disassembled, for example, partially disassembling it while retaining the fixed support part on the bed frame, which can save disassembly time. When it is used again, it can be quickly installed. Of course, the end connecting seat of the second frame 42 and the end connecting seat of the second support frame 6 can also be connected in other ways. The specific method should be flexibly selected according to the actual production and assembly situation, and the present invention does not limit it.

[0027] In some embodiments of the present invention, the two ends of the sleeve 1 and one end of the adjusting rod 3 are provided with threaded lines. The two ends inside the sleeve 1 are connected to the adjusting rod 3 along the spiral line to realize fine adjustment of the horizontal distance of the single bar. This connection structure is simple and easy to install. After the user adjusts it to the correct position, the position is automatically locked due to the friction and mechanical constraint of the differential thread.

[0028] In some embodiments of the present invention, the spiral lines at both ends of the sleeve 1 are greater than the spiral lines at one end of the adjusting rod 3. When the user adjusts the length of the bar, if the thread of the adjusting rod is found to be exposed, the length should not be increased further to ensure the user's safety. This can effectively prevent the bar from loosening unexpectedly under vibration or load, and improve the stability of the mechanism and operational safety.

[0029] By adjusting the installation position of the fixed support, the fixed position of the connecting sleeve, and the angle and position of the second support rod, the installation position of the bed frame or bed ladder can be flexibly changed. The installation position is basically centered around the bed frame. For example, it can also be installed on the bed ladder or bed frame, and different structures can be introduced to achieve the same effect.

[0030] This invention allows for flexible installation of a pull-up bar on a bed frame or ladder, making it more suitable for dormitory use than wall-mounted pull-up bars. It also offers a higher safety factor, is simple to use, and, without considering the extension or retraction of the bar, costs about the same as a regular pull-up bar. It essentially revolves around the bed frame, allowing for different structures to achieve the same effect. No need to go to a gym; you can use the pull-up bar anytime, anywhere, bringing exercise equipment into the dormitory.

[0031] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
