Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to an indoor horizontal bar. Background Technology

[0002] Indoor horizontal bars are a common piece of equipment in indoor fitness and entertainment facilities, widely used in home gyms, school gymnasiums, children's playgrounds, and other places, providing people with the convenience to perform various sports activities such as pull-ups and hanging exercises. Existing technology has the following limitations: First, the main support foot directly connected to the bar has a small support area, resulting in insufficient stability and safety; Second, if an auxiliary support foot is set to increase the support area, it is necessary to solve (1) the problem of torque transmission efficiency between the main support foot and the auxiliary support foot, (2) the problem of the setting position and space occupied by the transmission mechanism, and (3) the problem of the flexibility of the auxiliary support foot setting, how to make the auxiliary support foot able to adjust its posture and fit tightly against the wall. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an indoor horizontal bar to meet the needs of users.

[0004] To achieve the above objectives, this utility model provides an indoor horizontal bar, including a bar assembly and support assemblies disposed at both ends of the bar assembly. The bar assembly includes a main bar and telescopic bars extending outward from both ends of the main bar. The telescopic bars can be flexibly adjusted in length according to the indoor installation space and requirements, making it easy to adapt to different installation scenarios, while providing additional support length for the main bar.

[0005] The support components include

[0006] First supporting leg

[0007] The second support leg is located below the first support leg.

[0008] A drive unit, adapted to connect to the telescopic rod, the drive unit including a drive pin, the drive unit being slidably engaged with the first support leg.

[0009] The driven unit includes a driving end adapted to be drively connected to the driving unit and a driven end adapted to be drively connected to the second support leg. The driving end includes a slanted groove adapted to slide into the driving pin. The driven unit is pivotally connected to the first support leg via a first driven shaft.

[0010] When the drive unit moves down relative to the first support foot, the drive pin slides into the inclined groove, causing the active end to rise and the driven end to move down to drive the second support foot to press against the wall.

[0011] Preferably, the first support leg includes a first abutment portion adapted to conform to a wall surface, and the second support leg includes a second abutment portion adapted to conform to a wall surface. The first abutment portion and the second abutment portion are arranged parallel to each other. The first driven rotating shaft is arranged parallel to the first abutment portion, and the drive pin is arranged parallel to the first driven rotating shaft. Both the first abutment portion and the second abutment portion are elastic bodies with anti-slip textures or anti-slip protrusions. Since the horizontal bar is generally installed between a door frame or two walls, the wall surface abutted by the first and second abutment portions is a vertical surface, and the first and second abutment portions are also arranged vertically.

[0012] Preferably, the inclined groove is arranged perpendicular to the first driven shaft, the inclined groove is arranged along the extension direction of the driven unit, and the extension direction of the driven unit is defined as the extension direction from the driving end to the driven end.

[0013] Preferably, the driven unit includes a longitudinal plate and a transverse plate suitable for forming a T-shaped structure, wherein: the inclined groove is formed on the longitudinal plate, and the first driven rotating shaft is perpendicular to the plane of the longitudinal plate; and / or, the longitudinal plate can be divided into an active arm with an active end and a driven arm with a driven end, the length of the driven arm being 1.5 to 2 times the length of the active arm, utilizing the lever principle to enable the second support foot to stabilize the bar with a greater clamping force.

[0014] Preferably, the drive unit includes two drive lugs, the active end extends between the two lugs, the drive pin passes through the inclined groove, and both ends of the drive pin are mounted on the drive lugs.

[0015] Preferably, the first support foot includes two first ear plates, the driven unit extends between the two first ear plates, and a first driven rotating shaft passes through the driven unit, with both ends of the first driven rotating shaft mounted on the first ear plates. The second support foot includes two second ear plates, the driven unit extends between the two second ear plates, and a second driven rotating shaft passes through the driven end, with both ends of the second driven rotating shaft mounted on the second ear plates. The driven unit is arranged parallel to the driving ear plate, the first ear plate, and the second ear plate.

[0016] Preferably, the first support foot has a sliding surface, and the drive unit has a drive surface suitable for sliding contact with the sliding surface. The inclined groove provides a turning space for the active end relative to the drive device. The sliding surface can be arranged parallel to the first abutment portion, resulting in a more compact structure. Alternatively, the sliding surface can be inclined, and the sliding surface tends to move away from the first abutment portion from top to bottom. This design can increase the rotatable angle of the active end and provide more torque.

[0017] Preferably, the first support foot includes a sliding groove, which includes an open end and a closed end respectively disposed at its upper and lower ends. The sliding groove includes a groove bottom adapted to form the sliding surface and a groove opening disposed opposite to the groove bottom. The groove opening extends towards the middle to form a retaining edge disposed parallel to the groove bottom. Part of the driving unit slides into the sliding groove through the open end, and part of the driving unit extends out through the groove opening. The closed end is adapted to abut against the driving unit to restrict separation, and the retaining edge is adapted to limit the driving unit in a direction perpendicular to the sliding surface to restrict separation.

[0018] Preferably, the driven end is pivotally connected to the second support leg via a second driven shaft, and the second driven shaft is arranged parallel to the first driven shaft.

[0019] Preferably, one of the first and second support feet includes a first guide surface, and the other includes a second guide surface. The first and second guide surfaces slide in a direction perpendicular to the first abutment portion to guide the movement direction of the second support foot, ensuring the accuracy and stability of its movement trajectory. For example, during installation, this precise guidance ensures that the second support foot always abuts against the wall in a direction perpendicular to the wall, avoiding tilting or offset due to uneven force, and ensuring that the abutment force is evenly distributed on the contact surface, making the bar installation more secure and stable. On the other hand, it allows the second support foot to adapt to installation errors to a certain extent. In indoor installation environments, the flatness of the wall may vary. Guided by the guide surface, the second support foot can adjust its position within a certain range, allowing the abutment portion of the second support foot to better fit the uneven wall surface. When the second support foot encounters a protrusion or depression in the wall, it can adjust its position appropriately along the guide surface, ensuring that the entire support structure still functions, enabling the bar to achieve good installation results under various wall conditions.

[0020] Preferably, the first support leg has a guide cover at one end facing the second support leg, the guide cover having a first guide surface, and the second support leg has a guide post adapted to extend into the guide cover, the guide post having a second guide surface.

[0021] Preferably, the two second support legs are symmetrically arranged about the driven unit.

[0022] Preferably, the two second support legs are connected as a whole by a connecting beam, and the connecting beam is provided with a second ear plate.

[0023] As a preferred option, the first and second support feet can be made of high-strength engineering plastics, which have a certain degree of flexibility and high wear resistance, and can accommodate a certain amount of installation error while providing support, thus avoiding damage to the wall surface.

[0024] The beneficial effects of this utility model are:

[0025] By linking the first and second support legs through the active and driven units, and utilizing the lever principle and mechanical transmission, a large clamping force can be generated during installation. This achieves the effect of firmly pressing the second support leg against the wall, thereby effectively fixing the horizontal bar to the wall. This enhances the strength and stability of the horizontal bar, enabling it to withstand greater weight and external forces. It also reduces the risk of the horizontal bar loosening due to vibration or external forces during use, thus improving the safety and reliability of the product. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0032] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] like Figs. 1-3 The described indoor horizontal bar includes a bar assembly 1 and support assemblies 2 disposed at both ends of the bar assembly 1. The bar assembly 1 includes a main bar 11 and telescopic bars 12 extending outward from both ends of the main bar 11. The telescopic bars 12 can be flexibly adjusted in length according to indoor installation space and needs, making it easy to adapt to different installation scenarios, while providing additional support length for the main bar 11. The support assembly 2 includes a first support foot 21, a second support foot 22, a drive unit 23, and a driven unit 24. The first support foot 21 includes a first abutment portion 211 adapted to conform to the wall surface. The second support foot 22 is disposed below the first support foot 21 and includes a second abutment portion 221 adapted to conform to the wall surface. The first abutment portion 211 and the second abutment portion 221 are arranged parallel to each other. Both the first abutment portion 211 and the second abutment portion 221 are elastic bodies with anti-slip textures or anti-slip protrusions. A horizontal bar is typically installed between a door frame or two walls. The walls abutting the first abutment portion 211 and the second abutment portion 221 are vertical surfaces, and both abutment portions 211 and 221 are vertically positioned. The drive unit 23 is adapted to connect to the telescopic rod 12, and it slides with the first support leg 21. The driven unit 24 is pivotally connected to the first support leg 21 via a first driven pivot 246, which is parallel to the first abutment portion 211. The drive unit 23 includes a drive pin 231, which is parallel to the first driven pivot 246. The driven unit 24 includes an active end 241 and a driven end 242. The active end 241 includes a groove 243 adapted to slide with the drive pin 231, and the driven end 242 is drively connected to the second support leg 22. Furthermore, the inclined groove 243 is arranged perpendicular to the first driven rotating shaft 246, and the inclined groove 243 is arranged along the extension direction of the driven unit 24. The extension direction of the driven unit 24 is defined as the extension direction from the driving end 241 to the driven end 242.

[0034] When the drive unit 23 moves downward relative to the first support foot 21, the drive pin 231 slides into the inclined groove 243, causing the driving end 241 to rise, and the driven end 242 to move downward to drive the second support foot 22 to press against the wall. Specifically, the drive pin 231 applies a driving force to the driving end 241 in the downward direction. This driving force can be decomposed into an oblique component force along the extension direction of the inclined groove 243 and a vertical component force perpendicular to the inclined groove 243. The oblique component force causes the drive pin 231 to slide relative to the inclined groove 243, and the vertical component force acts on the driving end 241, causing the driving end 241 to rotate around the first driven shaft 246.

[0035] In this embodiment, the first support foot 21 includes a sliding groove 212, which includes an open end 213 and a closed end 214 respectively disposed at its upper and lower ends. The sliding groove 212 includes a groove bottom adapted to form a sliding surface 215 and a groove opening disposed opposite to the groove bottom. The groove opening extends towards the middle to form a retaining edge 216 disposed parallel to the groove bottom. The drive unit 23 forms a drive surface 233 adapted to slide and engage with the sliding surface 215. Part of the drive unit 23 slides into the sliding groove 212 through the open end 213, and part of the drive unit 23 extends out through the groove opening. The closed end 214 is adapted to abut against the drive unit 23 to restrict separation. The drive unit 23 also includes symmetrically disposed limiting strips 234. The retaining edge 216 and the limiting strips 234 constitute a limiting force in a direction perpendicular to the sliding surface 215 to restrict the separation of the drive unit 23 from the first support foot 21. The inclined groove 243 provides a space for the active end 241 to move and turn relative to the drive device. The sliding surface 215 is inclined and tends to move away from the first abutment portion 211 from top to bottom. This design can increase the rotation angle of the active end 241 and provide more torque. In some other embodiments, the sliding surface 215 can be arranged parallel to the first abutment portion 211, resulting in a more compact structure.

[0036] In this embodiment, the driven end 242 is pivotally connected to the second support leg 22 via a second driven pivot 247, which is parallel to the first driven pivot 246. A guide cover 217 is formed at the end of the first support leg 21 facing the second support leg 22. The guide cover 217 has a first guide surface 218, and the second support leg 22 correspondingly has a guide post 224 adapted to extend into the guide cover 217. The guide post 224 has a second guide surface 225. The first guide surface 218 and the second guide surface 225 slide in a direction perpendicular to the first abutment portion 211 to guide the movement direction of the second support leg 22, ensuring the accuracy and stability of its movement trajectory. For example, during installation, this precise guidance ensures that the second support leg 22 always presses against the wall in a direction perpendicular to the wall, avoiding tilting or offset due to uneven force, ensuring that the pressing force is evenly distributed on the contact surface, making the bar installation more secure and stable. Furthermore, it allows the second support leg 22 to accommodate installation errors to a certain extent. In indoor installation environments, the flatness of the wall surface may vary. Guided by the guide surface, the second support leg 22 can adjust its position within a certain range, allowing its contact part to better fit against uneven wall surfaces. When the second support leg 22 encounters a protrusion or depression in the wall surface, it can adjust its position appropriately along the guide surface, ensuring that the entire support structure still functions effectively. This allows the bar to achieve good installation results under various wall conditions.

[0037] In this embodiment, the driven unit 24 includes a longitudinal plate 248 and a transverse plate 249 adapted to form a T-shaped structure. A groove 243 is formed in the longitudinal plate 248, and a first driven shaft 246 is perpendicular to the plane of the longitudinal plate 248. The longitudinal plate 248 can be divided into an active arm 244 with an active end 241 and a driven arm 245 with a driven end 242. The length of the driven arm 245 is 1.8 times the length of the active arm 244. Utilizing the lever principle, the second support foot 22 can stabilize the bar with a greater clamping force. Specifically, the drive unit 23 includes two drive ear plates 232, with the active end 241 extending between the two ear plates. A drive pin 231 is disposed through the groove 243, and both ends of the drive pin 231 are mounted on the drive ear plates 232. The first support leg 21 includes two first ear plates 219, a longitudinal plate 248 extending between the two first ear plates 219, and a first driven rotating shaft 246 passing through the driven unit 24, with both ends of the first driven rotating shaft 246 mounted on the first ear plates 219. Two second support legs 22 are symmetrically arranged about the driven unit 24. The two second support legs 22 are connected as a whole by a connecting beam 222, and two second abutment portions 221 are integrally formed. A second ear plate 223 is provided above the connecting beam 222, a driven end 242 extending between the two second ear plates 223, and a second driven rotating shaft 247 passing through the driven end 242, with both ends of the second driven rotating shaft 247 mounted on the second ear plates 223. The longitudinal plate 248 is arranged parallel to the driving ear plate 232, the first ear plates 219, and the second ear plates 223. The first support legs 21 and the second support legs 22 can be made of high-strength engineering plastics, possessing a certain degree of flexibility and high wear resistance, allowing them to accommodate certain installation errors while providing support and preventing damage to the wall surface.
