Description

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 door frame support. 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 with a door frame support.

[0005] The purpose of this utility model is achieved as follows:

[0006] A horizontal bar with a door frame support includes a retractable horizontal bar with abutment seats fixed at both ends; it also includes two lateral support plates that can abut against a wall or door frame surface; the sides of the lateral support plates are provided with connecting parts, and the ends of the abutment seats are provided with engaging parts 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; the back of the lateral support plates is fixed to the wall or door frame surface and / or the lower end of the lateral support plates abuts against the ground; the lateral support plates cannot be extended or retracted along their length; the lateral support plates on both sides simultaneously support the horizontal bar to prevent it from sliding downwards;

[0007] Several connecting parts are arranged longitudinally above the lateral support plate, and the engaging part of the abutment can stay on any of the connecting parts.

[0008] The abutment seat has several engagement portions arranged longitudinally 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 arranged longitudinally; 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.

[0009] The interlocking part is a protrusion, and the connecting part is a groove.

[0010] The end of the abutment is provided with soft rubber, and the biting part is located on both sides of the soft rubber; when the bar is locked, the two ends of the abutment abut against the surface of the side support plate through the soft rubber, and at the same time, the biting part and the connecting part abut against each other.

[0011] 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.

[0012] 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.

[0013] The back of the lateral support plate has a flat surface, which is fixed to the surface of the wall or door frame by adhesive bonding.

[0014] The lower end of the lateral support plate is fixedly provided with a base plate, which has a bent portion, and the lower end of the base plate is supported on the ground.

[0015] The lateral support plate is formed by fixing several plates together.

[0016] The lower rear end of the board has a slot, and the upper end of the board has a plug that can be locked into the slot; or, it includes a connector, the two ends of which are respectively inserted into adjacent boards and connected to the adjacent boards.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] 1. This utility model adopts a lateral support plate that abuts against the surface of a wall or door frame. In use, the lateral support plate not only provides support for the single bar but also occupies little space, making the entire product more aesthetically pleasing. The lateral support plate is a longitudinal plate and cannot be extended or retracted longitudinally, thus providing better support capacity.

[0019] 2. The horizontal bar features multiple supports during use: Support position 1: The abutments at both ends of the bar are engaged with the connecting parts of the lateral support plates, which provide upward support to the bar. Support position 2: The abutments at both ends rest against the surface of the lateral support plates via soft rubber, meaning the bar rests laterally against the lateral support plates, which in turn rest against a wall or door frame. These two support positions enhance the overall stability of the product, making it more stable during use.

[0020] 3. 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.

[0021] 4. The lateral support plate of this utility model has an inlet on its side, which connects to the connecting part. The engaging part of the abutment can enter the connecting part. By providing the 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 and placed on the corresponding connecting part, and then the bar can be locked.

[0022] 5. The side support plate of this utility model adopts a multi-section splicing method, and the plates are connected face to face to ensure the stability of the structure. Moreover, the bottom plate of the side support plate can be a vertical plate or a shape with a bend, which avoids the baseboard of the house and allows the lower end of the bottom plate to be supported on the ground.

Detailed Implementation

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-18 As shown:

[0043] A horizontal bar with a door frame support includes a retractable horizontal bar 2. The horizontal bar 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 retractable horizontal bar support rod of Chinese patent CN202222185311.2, CN202222168834.6, a ratchet lock sleeve for a horizontal bar on a door, and CN202221019171.5, a horizontal bar on a door. The retractable horizontal bar structure disclosed in the above prior patents can be used, 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 plane, which refers to the surface of a wall or door frame; the side of the lateral support plate 1 is provided with a connecting part 112, and the end of the abutment seat 21 is provided with an engagement part 211 that cooperates with the connecting part 112. The abutment seats 21 at both ends of the horizontal bar 2 are limited to the connecting part 112 of the lateral support plate 1 by the engagement part 211; the back of the lateral support plate 1 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 can be fixed to the wall by adhesive connection, or the lower end of the longitudinal support plate abuts against the ground. The manufacturer can choose one of the fixing methods or both of the fixing methods at the same time. Preferably, the lateral support plate 1 cannot extend or retract along its length. The lateral support plates 1 on both sides abut against the ground and are also fixed to the wall or door frame surface by adhesive. The two lateral support plates 1 support the horizontal bar 2 simultaneously to prevent the horizontal bar 2 from sliding downward.

[0044] Several connecting parts 112 are longitudinally arranged above the lateral support plate 1, and the engaging part 211 of the abutment 21 can stay on any of the connecting parts 112. By setting several engaging parts 211 to engage simultaneously on the corresponding connecting parts, simultaneous multi-position engagement is achieved, ensuring the stability of mutual fixation; even if one connecting part slips or misaligns, the remaining connecting parts can still provide effective support for the arch.

[0045] The abutment 21 has several engagement parts 211 arranged longitudinally on both sides. When the abutment 21 is connected to the lateral support plate 1, the engagement parts 211 engage with the corresponding connecting parts 112 simultaneously. By arranging the engagement parts on both sides of the abutment, the support effect is better, the abutment is less prone to axial torsion, and the stability is better when multiple engagement parts engage simultaneously.

[0046] The engagement portion 221 is a protrusion, and the connecting portion 112 is a groove. Conversely, the same technical solution applies if the engagement portion is a groove and the connecting portion is a protrusion. The protrusion can extend to both sides or outwards, and the specific orientation of the protrusion is determined by the manufacturer.

[0047] The end of the abutment 21 is provided with soft rubber 212, and the biting part 211 is located on both sides of the soft rubber 212. When the bar is locked, the two ends of the abutment abut against the surface of the lateral support plate through the soft rubber, and at the same time, the biting part and the connecting part abut against each other. That is, the bar is supported at multiple positions at the same time, making the bar more stable and safer for the user.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The lateral support plate 1 is formed by fixing several plates 11 together. The mutual fixing method facilitates the transportation of the lateral support plate 1, and the length of the lateral support plate 1 is also more flexible, allowing the manufacturer to set the appropriate length of the lateral support plate for the user.

[0052] 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 made 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 abutted against the wall or door frame surface, the boards will not separate.

[0053] 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 or plastic 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.

[0054] 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.

[0055] 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 a series of teeth engaging, ensuring the stability of the connection. 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.

[0056] 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 through the inlet. The inlet facilitates user assembly; the bar is adjusted to its approximate length and then inserted through the inlet 116 and placed on the corresponding connecting part 112, after which the bar is locked.

[0057] 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.
