Technical Field
[0001] This utility model belongs to the technical field of door-mounted single bar structure, specifically referring to a single bar with a stable structure. Background Technology
[0002] A door-mounted horizontal bar is a fitness equipment used to exercise the arms, waist, and abdomen. Currently available door-mounted horizontal bars consist of a tube and a pair of retractable bars installed inside the tube. The bars are threaded into the tube; rotating the bars extends or retracts them, allowing each bar to press against a wall. However, current technology is not perfect. Existing door-mounted horizontal bars rely on the friction between the wall and the bars for support, resulting in a simple support structure that is prone to slippage, instability, and safety hazards.
[0003] Therefore, to increase the strength and safety of the door-mounted horizontal bar, support rods are installed on both sides of the bar, such as in Chinese Patent CN202122049091.6, which aims to overcome the problem of unstable support in existing technologies. It includes a door-mounted horizontal bar with support rods at both ends below it. These support rods provide auxiliary support to the bar. Each support rod includes at least an outer tube and an inner tube. The inner tube is located below the bar, and the inner tube slides inside the outer tube. The lengths of the inner and outer tubes are relatively adjustable. A support member is installed at the end of the inner tube, supporting the lower end of the bar. When the bar is fixed to the wall, the wall provides support, and the support rods also provide support, thus providing dual support. This product improves stability, but it also has some shortcomings: the side support rods are retractable, and it's uncertain whether they can support the weight of a person if the bar slides down; moreover, there is a large gap between the support rods and the door frame, affecting user passage, and the product is not aesthetically pleasing. Summary of the Invention
[0004] The purpose of this invention is to provide a structurally stable single bar.
[0005] The purpose of this utility model is achieved as follows:
[0006] A structurally stable horizontal bar includes a retractable horizontal bar with abutment seats fixedly installed at both ends; it also includes two lateral support plates that can be abutted against a wall or door frame surface; the lateral support plates have connecting parts on their sides, and the abutment seats have engaging parts at their ends that cooperate with the connecting parts; the abutment seats at both ends of the horizontal bar are limited to the connecting parts of the lateral support plates by the engaging parts; when the horizontal bar is locked, the two ends of the abutment seats abut against the surface of the lateral support plates with soft rubber, and at the same time, the engaging parts and the connecting parts abut against each other;
[0007] The back of the lateral support plate is fixed to the surface of the wall or door frame and / or the lower end of the lateral support plate abuts against the ground; the lateral support plate is formed by several plates fixed to each other to form a complete structure, the lateral support plate cannot be extended or retracted longitudinally, and the lateral support plates on both sides support the bar simultaneously to prevent the bar from sliding downward.
[0008] The lateral support plate has a flat surface on its back, which is used to fix the lateral support plate to the surface of the wall or door frame by means of flat adhesive bonding; or, the lateral support plate is fixed to the surface of the wall or door frame by means of fasteners.
[0009] The panels are fixed together by interlocking; the lateral support plates are fixed to the surface of the wall or door frame, and the panels in the middle cannot be removed separately.
[0010] A slot is provided at the lower rear of the board, and a plug is provided at the upper end of the board, which can be locked into the slot.
[0011] The slot has a blocking surface on the surface of the plate. The opening of the slot is located on the rear surface of the plate. The plug extends into the slot through the opening and abuts against the blocking surface. The plug cannot be removed from the blocking surface.
[0012] It includes a connector, the two ends of which are inserted into adjacent boards and connected to the adjacent boards.
[0013] The plate is a metal profile or a plastic profile, and the plate has a cavity. A box is set inside the cavity, and the connecting part is located inside the box.
[0014] The abutment seat has several engagement portions longitudinally arranged on both sides. When the abutment seat is connected to the lateral support plate, the engagement portions simultaneously engage with the corresponding connecting portions. Alternatively, the outer surface of the abutment seat has several abutment seat teeth longitudinally arranged; the lateral support plate has plate teeth that mate with the abutment seat teeth, the number of plate teeth being greater than the number of abutment seat teeth. When the abutment seat is connected to the lateral support plate, the abutment seat teeth simultaneously engage with the corresponding plate teeth.
[0015] The engagement part is a protrusion, and the connecting part is a groove; the end of the abutment is provided with soft rubber, and the engagement part is located on both sides of the soft rubber; the lower end of the lateral support plate is fixedly provided with a base plate, the base plate is provided with a bending part, and the lower end of the base plate is supported on the ground.
[0016] The end of the lateral support plate is recessed inward to form an inner cavity, and the connecting parts are longitudinally arranged on both sides of the inner cavity.
[0017] The side of the lateral support plate is provided with an inlet, which is connected to the connecting part. The engaging part of the abutment can enter the connecting part through the inlet.
[0018] The outstanding and beneficial technical effects of this utility model compared to the prior art are:
[0019] 1. This utility model employs a lateral support plate that abuts against a wall or door frame surface. In use, the lateral support plate not only provides support for a single bar but also occupies little space, making the entire product more aesthetically pleasing. The lateral support plate is a longitudinally oriented panel that cannot be extended or retracted longitudinally, thus providing superior support capacity. The lateral support plate uses a multi-section splicing method, with the panels meeting face-to-face to ensure structural stability. The splicing of multiple panels reduces transportation costs and allows manufacturers to freely determine the actual length of the lateral support plate, increasing their control.
[0020] 2. In this invention, the panels are fixed together by interlocking, ensuring structural stability. Furthermore, the lateral support plate is fixed to the surface of the wall or door frame, and the central panel cannot be removed individually. Users can only remove the panels one by one from top to bottom or bottom to top, or remove the entire lateral support plate, thus preventing accidental detachment of the central panel and ensuring its stability. Preferably, the slot has a blocking surface on the surface of the panel, with the slot opening located on the rear surface of the panel. The plug extends into the slot through the opening and rests against the blocking surface. The plug cannot be removed from one side of the blocking surface. Due to the blocking surface, the central panel cannot be removed independently when the lateral support plate is installed on the surface of the wall or door frame.
[0021] 3. The horizontal bar features multiple supports during use: Support position 1: The abutments at both ends of the bar are secured to the connecting parts of the lateral support plate via interlocking parts, providing upward support to the bar. Support position 2: The abutments at both ends rest against the surface of the lateral support plate via soft rubber, meaning the bar rests laterally against the lateral support plate, which in turn rests against a wall or door frame surface. These two support positions enhance the overall stability of the product, making it more stable during use.
[0022] 4. In this utility model, the abutment and the connecting seat are connected by a two-sided interlocking method. Several interlocking parts are longitudinally arranged on both sides of the abutment. When the abutment is connected to the support plate, these interlocking parts simultaneously engage with the corresponding connecting parts, making the connection more stable and preventing accidental slippage. The abutment has interlocking parts on both sides, and the middle section can be used to install soft rubber, allowing the horizontal bar to rest against the surface of the lateral support plate.
[0023] 5. The lateral support plate of this utility model is provided with an inlet on its side, which connects to the connecting part. The engaging part of the abutment can enter the connecting part. By providing an inlet, it is convenient for users to assemble the bar. After adjusting the bar to the approximate length, it can be inserted through the inlet and placed on the corresponding connecting part, and then the bar can be locked. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-18 As shown:
[0045] A structurally stable horizontal bar includes a retractable horizontal bar 2. The horizontal bar 2 is prior art, therefore this application does not describe the specific structure of the horizontal bar. Any retractable horizontal bar on the market can be used, such as the support rod for a fitness horizontal bar in Chinese patent CN202222185311.2, the ratchet lock sleeve for a horizontal bar on a door in CN202222168834.6, and the horizontal bar on a door in CN202221019171.5. Any retractable horizontal bar structure disclosed in the above prior patents is acceptable, as long as the horizontal bar can be retracted and adjusted. The horizontal bar 2 has abutment seats 21 fixedly installed at both ends; it includes two lateral support plates 1, which can be abutted against a flat surface, such as a wall or door frame. A connecting portion 112 is provided on the side of the lateral support plate 1, and an engaging portion 211 that mates with the connecting portion 112 is provided at the end of the abutment seat 21. The abutment seats 21 at both ends of the horizontal bar 2 are limited to the connecting portion 112 of the lateral support plate 1 by the engaging portion 211. When the horizontal bar 2 is locked, the two ends of the abutment seats 21 abut against the surface of the lateral support plate 1 through the soft rubber 212, while the engaging portion 211 and the connecting portion 112 abut against each other. Preferably, the engaging portion is located on both sides of the soft rubber. This multi-position support makes the horizontal bar more stable and safer for the user.
[0046] The back of the lateral support plate is fixed to the surface of the wall or door frame, and the lower end of the lateral support plate abuts against the ground. The lateral support plate 1 is formed by fixing several plates 11 together. The lateral support plate 1 cannot be extended or retracted longitudinally. The lateral support plates 1 on both sides support the bar simultaneously to prevent the bar from sliding downward. The plates 11 are fixed together to each other, which facilitates the transportation of the lateral support plate 1. Moreover, the length of the lateral support plate 1 is more flexible. The manufacturer can set the lateral support plate of the appropriate length for the user.
[0047] The back of the lateral support plate 1 is provided with a flat surface 119. This flat surface can be a naturally formed flat surface or it can be formed by fixing a flat plate. The specific flat surface configuration is determined by the manufacturer. The flat surface 119 is fixed to the surface of the wall or door frame by adhesive. Alternatively, the lateral support plate can be fixed to the door frame or wall by fasteners, with adhesive bonding being preferred. Soft glue or foam adhesive can be used for fixation, facilitating disassembly by the user later.
[0048] The panels 11 are fixed together by interlocking. Connecting parts can be placed on the top panel or on all panels; the specific design of the connecting parts is determined by the manufacturer. The side support plate 1 is fixed to the surface of the wall or door frame. The middle panel 11 cannot be removed individually. Users can only remove the panels one by one from top to bottom or bottom to top, or remove the side support plate as a whole, thus preventing accidental detachment of the middle panel and ensuring the stability of the side support plate. Preferably, a slot 113 is provided at the lower rear end of the plate 11, and a plug 114 is provided at the upper end of the plate 11. The plug 114 can be locked in the slot 113. At least one pair of slots 113 and plugs 114 are provided. Two pairs of slots and plugs are provided in the attached figure. Furthermore, a blocking surface 1131 is provided on the surface of the plate 113. The opening of the slot is located on the rear surface of the plate. The plug 114 extends into the slot through the opening and abuts against the blocking surface 1131. The plug 114 cannot be moved out from one side of the blocking surface 1131. Under the action of the blocking surface 1131, when the lateral support plate 1 is installed on the surface of the wall or door frame, the middle plate 11 cannot be removed independently.
[0049] The abutment 21 has several engagement portions 211 longitudinally arranged on both sides. When the abutment 21 is connected to the lateral support plate 1, the engagement portions 211 simultaneously engage with the corresponding connecting portions 112. By setting several engagement portions 211 to engage with the corresponding connecting portions 112 simultaneously, simultaneous multi-position engagement is achieved, ensuring the stability of mutual fixation; even if one connecting portion 112 slips or misaligns, the remaining connecting portions 112 can still provide effective support for the arch. Furthermore, by setting the engagement portions 211 on both sides of the abutment 21, the support effect of the two-sided engagement is better, the abutment 21 is less prone to axial torsion, and the simultaneous engagement of multiple engagement portions 211 provides better stability.
[0050] The engagement portion 211 is a protrusion, and the connecting portion 112 is a groove. Conversely, the same technical solution applies if the engagement portion 211 is a groove and the connecting portion 112 is a protrusion. The protrusion can extend to both sides or outwards, and the specific orientation of the protrusion is determined by the manufacturer.
[0051] A base plate 12 is fixedly installed at the lower end of the lateral support plate 1. The base plate 12 has a bending part 121, which can avoid the baseboard of the house. The lower end of the base plate 12 is supported on the ground. Of course, a base plate without a bending part can also be selected, depending on the actual situation of the user's home.
[0052] The lateral support plate 1 is recessed inward at one end to form an inner cavity 111, and the connecting portions 112 are longitudinally arranged on both sides of the inner cavity 111. By setting the inner cavity 111, the abutment 21 is partially inserted into the cavity 111, thus concealing the connection position. Moreover, the inner cavity 111 and the abutment 21 are adapted to each other, allowing the abutment 21 to be properly positioned and preventing lateral twisting. This allows the abutment 21 to move up and down within the cavity 111 for adjustment. The built-in structure limits the range of motion of the abutment, allowing the user to adjust it within a limited range.
[0053] Example 1: As Figure 1-7 As shown in the figure, a slot 113 is provided at the lower rear end of the board 11, and a plug 114 is provided at the upper end of the board 11. The plug 114 can be locked into the slot 113. The connection is more stable by interlocking. Preferably, at least one pair of slots 113 and plugs 114 are provided. Two pairs of slots and plugs are shown in the figure. Preferably, the slots do not penetrate through the board. After the two boards are connected, the plug will not protrude from the slot. When the lateral support plate is connected and abuts against the wall or door frame surface, the boards will not separate.
[0054] Example 2: Figure 8-10As shown. The difference between Embodiment 2 and Embodiment 1 lies in the connection method of the lateral support plate. It includes a connector 14, with both ends of the connector 14 inserted into adjacent plates and connecting them to the adjacent plates 11. Preferably, the plates 11 can be made of metal profiles, resulting in a stronger lateral support plate 1. The profiles are connected to each other via connectors. Preferably, the profiles have open slots, and a box 13 is provided in the open slots, with corresponding connecting parts 112 inside the box 13.
[0055] Example 3: As Figure 11-13 As shown. The difference between Embodiment 3 and Embodiment 1 lies in the engagement method between the lateral support plate and the abutment. Engaging parts 211 are provided on the outer sides of both sides of the lateral support plate 1, and the lateral support plate 1 and the abutment 21 engage on both sides, with the soft rubber 212 in the middle of the abutment 21 pressing against the lateral support plate 1.
[0056] Example 4: Figure 14-15 As shown in the attached figure. The difference between Embodiment 4 and Embodiment 1 lies in the engagement method between the lateral support plate and the abutment. The lateral support plate 1 has plate teeth 115 on its surface, and the abutment 21 has corresponding abutment teeth 213. The two are fixedly connected by the engagement of the teeth. The plate teeth on the lateral support plate can be selected according to the actual needs of the manufacturer. As shown in the attached figure, all plates can be provided with plate teeth, or plate teeth can be provided at the required positions.
[0057] Example 5: Figure 16-18 As shown. The difference between Embodiment 5 and Embodiment 1 lies in the engagement method between the lateral support plate and the abutment. The lateral support plate 1 has an inlet 116 on its side, which connects to the connecting part 112. The engaging part 211 of the abutment can enter the connecting part 112. By providing an inlet, it is convenient for the user to assemble the bar. After adjusting the bar to the approximate length, it can be inserted through the inlet 116 and placed on the corresponding connecting part 112, and then the bar can be locked.
[0058] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
