Description

Technical Field

[0001] The utility model relates to the technical field of horizontal bars, in particular to a horizontal bar for doors. Background Art

[0002] A horizontal bar for doors is a fitness equipment, usually installed on the door frame, mainly used for performing actions such as pull-ups and pull-downs to exercise the strength and endurance of parts such as the back, biceps, and triceps.

[0003] Patent No. US11484746B2 discloses a foldable fitness device, which is essentially a horizontal bar for doors. More specifically, as Figure 11 shown, reference numerals 20'-21' are the door frame members to which the foldable fitness device is attached, reference numerals 10'-16' are the members of the foldable fitness device, and reference numerals A1'-A2' are two holding positions on the left side of the foldable fitness device. In this device, the upper end of the top horizontal member 11' is fixed to the upper end of the connecting member 16', the lower end of the connecting member 16' is fixed to the bottom horizontal member 15', a sleeve 14' is movably sleeved on the connecting member 16', the pull-up handle 10' and the door lintel hook 13' are respectively fixed on both sides of the sleeve 14'. When the sleeve 14' is rotated, the pull-up handle 10' and the door lintel hook 13' move synchronously. When the door lintel hook 13' hooks the door lintel 20', a positioning pin and a spring (not shown in the figure) are installed inside the connecting member 16' to position the sleeve 14'. From the above process, it can be seen that when the door lintel hook 13' hooks the door lintel 20', the pull-up handle 10' is fixed outward. When the user holds the two outer holding positions A1' and performs a pull-up, the two outwardly extending pull-up handles 10' will form an obstruction and limit the user's ascent, causing inconvenience.

[0004] Therefore, it is still necessary to improve the existing horizontal bar for doors to solve the problem that the pull-up handle of the existing horizontal bar for doors brings inconvenience to users. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a horizontal bar for doors to solve the problem that the pull-up handle of the existing horizontal bar for doors brings inconvenience to users.

[0006] To achieve the above object, the present utility model provides a single bar on a door. The single bar on the door includes two intermediate components, and a lower crossbar and an upper crossbar arranged in sequence along the ascending direction of the user. The intermediate component includes a connecting rod connecting the upper crossbar and the lower crossbar, a pull-up handle rotating around the connecting rod, and a door lintel hook. One end of the door lintel hook away from the door lintel is fixed to the lower crossbar. The active positions of the pull-up handle include an extended position and a staggered position. When in the extended position, the pull-up handle is located in the ascending direction of the user and is for the user to hold. When in the staggered position, the user holds the upper crossbar, and the pull-up handle is staggered from the ascending direction of the user.

[0007] In some embodiments, along the axial direction of the lower crossbar, the door lintel hook is located between the end of the connecting rod and the lower crossbar. Both sides of the upper crossbar are provided with holding areas. The holding areas include a first holding position, a second holding position, and a third holding position arranged in sequence along the axial direction of the upper crossbar. The connecting rod is located between the first holding position and the second holding position. The second holding position is adjacent to the third holding position.

[0008] In some embodiments, the second holding position is a horizontal holding area; the third holding position is a downward-sloping holding area.

[0009] In some embodiments, the single bar on the door further includes two detachable connection components corresponding to the two door lintel hooks respectively. The detachable connection components are used to detachably connect the door lintel hooks and the lower crossbar.

[0010] In some embodiments, the detachable connection component includes a sleeve and a bolt. The sleeve is fixed to one end of the door lintel hook away from the door lintel, and the sleeve is sleeved on the lower crossbar. The bolt is used to connect the sleeve and the lower crossbar.

[0011] In some embodiments, the door lintel hook is a pipe fitting. The bolt penetrates through the sleeve, the lower crossbar, and the door lintel hook, and the tail end of the bolt is located inside the door lintel hook.

[0012] In some embodiments, taking the side of the lower crossbar facing the door lintel hook and fixed to it as the rear side, and the back of the rear side as the front side; the detachable connection component includes a bolt, a front annular piece fitting the front side, and a rear annular piece fitting the rear side. The door lintel hook is a pipe fitting. The bolt penetrates through the front annular piece, the lower crossbar, the rear annular piece, and the door lintel hook, and connects the front annular piece, the lower crossbar, and the rear annular piece. Along the ascending direction of the user, there is a gap between the lower ends of the front annular piece and the rear annular piece. The gap is used for the front annular piece to deflect downward to abut against the rear annular piece when bearing the downward pulling force of the user, so as to achieve common force bearing.

[0013] In some embodiments, the lintel hook is a telescopic hook.

[0014] In some embodiments, a widened connecting piece is fixedly provided at one end of the connecting rod facing the lower cross bar; the widened connecting piece is aligned with and fixed to the lower cross bar.

[0015] In some embodiments, a connecting ring is installed in the middle of the upper cross bar, and the connecting ring is used to connect the stretching fitness equipment.

[0016] Compared with the prior art, the utility model has the beneficial effect that the movement states of the pull-up handle and the door lintel hook are independent of each other, and the use method is more flexible and comfortable. Specifically, when the door lintel hook is hooked on the door lintel, since the pull-up handle can move independently on the connecting rod, the pull-up handle can be used in a variety of ways. For example, the pull-up handle can be rotated to the extended position for the user to hold and perform pull-ups. For another example, the pull-up handle can be rotated to the staggered position so that the pull-up handle is staggered with the user's ascending direction. At this time, the user's ascending direction is not blocked and there is more room for movement. When the user holds the upper cross bar to perform pull-ups, the movement is more comfortable.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] A single-bar on a door is a fitness equipment, usually installed on the door frame, mainly used for performing actions such as pull-ups and pull-downs to exercise the strength and endurance of parts such as the back, biceps brachii, and triceps brachii.

[0030] In the prior art, when the door lintel hook hooks the door lintel, the pull-up handle is fixed facing outwards. When the user holds the two holding positions on the outside and performs a pull-up, the two outward-extending pull-up handles will form an obstruction and limit the user's ascent, causing inconvenience.

[0031] An embodiment of the present utility model provides a single-bar 1 on a door, as Figures 1 to 4 shown. The single-bar 1 on the door includes two middle components 10, and a lower crossbar 11 and an upper crossbar 12 arranged in sequence along the user's ascending direction Z. The middle component 10 includes a connecting rod 100 that fixedly connects the upper crossbar 12 and the lower crossbar 11, a pull-up handle 101 that rotates around the connecting rod 100, and a door lintel hook 102. One end of the door lintel hook 102 facing away from the door lintel (not shown in the figure) is fixed to the lower crossbar 11. The moving positions of the pull-up handle 101 include an extended position 1010 and a staggered position 1011. When in the extended position 1010, the pull-up handle 101 is located in the user's ascending direction Z and is for the user to hold. When in the staggered position 1011, the user holds the upper crossbar 12, and the pull-up handle 101 is staggered from the user's ascending direction Z.

[0032] Compared with the prior art, the beneficial effects of the present utility model are as follows: The movement states of the pull-up handle 101 and the lintel hook 102 are independent of each other, and the usage method is more flexible and comfortable. Specifically, when the lintel hook 102 hooks the lintel, since the pull-up handle 101 can move independently on the connecting rod 100, the pull-up handle 101 has various usage methods. For example, the pull-up handle 101 can be rotated to the extended position 1010 for the user to hold and perform pull-ups. Another example is that the pull-up handle 101 can be rotated to the staggered position 1011 so that the pull-up handle 101 is staggered from the user's ascending direction Z. At this time, there is no obstruction in the user's ascending direction and there is more activity space, and the user can move more freely when holding the upper crossbar 12 to perform pull-ups.

[0033] In the single-bar on the door 1:

[0034] (1) Regarding the intermediate component 10, it refers to the component that is roughly located between the lower crossbar 11 and the upper crossbar 12. More specifically, it means that at least one of the parts included in the component is located between the lower crossbar 11 and the upper crossbar 12, such as the connecting rod 100.

[0035] (2) The user's ascending direction Z is parallel to the height direction of the door frame.

[0036] (3) The lower crossbar 11 can be a one-piece formed rod or a rod composed of multiple segments; in addition, in addition to being cylindrical as a whole, the lower crossbar 11 can also adopt other shapes such as square.

[0037] (4) The upper crossbar 12 can be a one-piece formed rod or a rod composed of multiple segments.

[0038] (5) Regarding the extended position 1010. Only one can be set, and a position perpendicular to the lower crossbar 11 is selected. At this time, the pull-up handle 101 is perpendicular to the lower crossbar 11, which is more convenient for the user to hold.

[0039] (6) Regarding the staggered position 1011. Multiple can be set, such as the position rotated 90° from the extended position 1010 towards the lintel hook 102, another example is the position rotated 120° from the extended position 1010 towards the lintel hook 102, and another example is the position rotated 150° from the extended position 1010 towards the lintel hook 102, mainly to meet the requirement of being staggered from the user's ascending direction Z.

[0040] 1. Regarding the rotational connection between the connecting rod 100 and the pull-up handle 101

[0041] 1.1 In some embodiments, as Figure 1 、 Figures 5 to 7 shown, for the rotational connection between the connecting rod 100 and the pull-up handle 101, Scheme 1 can be adopted:

[0042] The intermediate component 10 further includes a sleeve 103, a positioning pin 104, and a spring 105; the sleeve 103 is adapted to the connecting rod 100, and the pull-up handle 101 is fixed to the sleeve 103. Therefore, the pull-up handle 101 and the sleeve 103 rotate synchronously around the connecting rod 100; the spring 105 is located inside the connecting rod 100 and is coaxial with the connecting rod 100. The two ends of the spring 105 respectively abut against the connecting rod 100 and the positioning pin 104, or respectively abut against the upper crossbar 12 and the positioning pin 104. The spring 105 exerts a downward pressure on the positioning pin 104, causing the positioning pin 104 to abut against the sleeve 103, playing a limiting role.

[0043] 1.1.1 Based on the solution provided in 1.1, further, in some embodiments, as Figure 5 shown, at one end of the sleeve 103 facing the lower crossbar 11, a card slot 1030 is provided. The positioning pins 104 are inserted through the upper and lower ends of the connecting rod 100. Different from this, the positioning pin 104 close to the upper crossbar 12 can move up and down with the spring 105, and the positioning pin 104 close to the lower crossbar 11 is fixed. The positioning pin 104 close to the lower crossbar 11 mainly cooperates with the card slot 1030 to hold the sleeve 103 when the pull-up handle 101 is in the extended position 1010, preventing the sleeve 103 and the pull-up handle 101 from accidentally deflecting when the user does pull-ups and ensuring the safety of use.

[0044] 1.2 In some embodiments, the rotational connection between the connecting rod 100 and the pull-up handle 101 can adopt Solution Two:

[0045] The intermediate component 10 further includes a sleeve 103 and bumps (not shown in the figure). Different from Solution One provided in 1.1, in Solution One, the sleeve 103 is positioned by the positioning pin 104 and the spring 105, while in Solution Two, positioning is achieved by a groove (not shown in the figure) and an elastic bump made of rubber. The groove and the bump are adapted. One of the inner surface of the sleeve 103 and the outer surface of the connecting rod 100 is provided with one or more grooves, and the other is fixed with one or more bumps. When the pull-up handle 101 is in the extended position 1010, the bump cooperates with the groove to hold the sleeve 103, preventing the sleeve 103 and the pull-up handle 101 from accidentally deflecting when the user does pull-ups and ensuring the safety of use.

[0046] 2. Regarding the setting method of the lintel hook 102 and the connecting rod 100

[0047] 2.1 In some embodiments, as Figure 1 shown, the setting method of the lintel hook 102 and the connecting rod 100 can adopt Solution One:

[0048] Along the axial direction of the lower cross bar 11, the lintel hook 102 is located between the ends of the connecting rod 100 and the lower cross bar 11; gripping areas 120 are provided on both sides of the upper cross bar 12; the gripping area 120 includes a first gripping position 1200, a second gripping position 1201 and a third gripping position 1202 arranged in sequence along the axial direction of the upper cross bar 12; the connecting rod 100 is located between the first gripping position 1200 and the second gripping position 1201; the second gripping position 1201 is adjacent to the third gripping position 1202. The advantage of the above structure is that, on the one hand, when the lintel hook 102 is relatively outward, it can adapt to a wider door distance and the connection stability is better. On the other hand, more gripping positions can be provided to optimize the fitness experience. Specifically, the connecting rod 100 is staggered with the door lintel hook 102, and the connecting rod 100 is offset inward, leaving space for adding a gripping position, so that three gripping positions (i.e., the first gripping position 1200, the second gripping position 1201, and the third gripping position 1202) can be provided on one side of the upper crossbar 12. By providing multiple gripping positions, different arm widths and different training movements can be adapted, bringing a better fitness experience to users. In sharp contrast, Figure 11 In the conventional horizontal bar on the door shown, the connecting rod 100 and the pull-up handle 101 are relatively outward, occupying the space of the gripping position, so that the upper cross bar 12 can only provide two gripping positions on one side, which has certain limitations on the arm width and training movements.

[0049] 2.2 In some embodiments, the door lintel hook 102 and the connecting rod 100 may be arranged in the second scheme:

[0050] The connecting rod 100 is located between the door lintel hook 102 and the end of the lower cross bar 11. Although the connecting rod 100 is relatively outward, it still leaves enough space for the second gripping position 1201. At the same time, since the door lintel hook 102 is relatively inward, it can adapt to a narrower door distance.

[0051] In some embodiments, Figure 1 As shown, accessories for increasing friction are provided on the corresponding gripping positions, including but not limited to foam 13 and rubber sleeves.

[0052] 3. About the setting method of the second holding position 1201 and the third holding position 1202

[0053] 3.1 In some embodiments, Figure 1 As shown, the second holding position 1201 and the third holding position 1202 may be arranged in a manner as follows:

[0054] The second holding position 1201 is a horizontal holding area; the third holding position 1202 is a downward-inclined holding area. The arm-opening angle and the palm-inclination angle corresponding to the horizontal holding area are significantly smaller than those corresponding to the downward-inclined holding area. Therefore, fitness actions corresponding to different difficulty levels can be provided, which helps to meet the diverse fitness needs of users.

[0055] 3.2 In some embodiments, the second holding position 1201 and the third holding position 1202 can be arranged in accordance with Solution 2:

[0056] Both the second holding position 1201 and the third holding position 1202 are horizontal holding areas. Different holding positions can adapt to the physical conditions and training needs of different users. For example, some users may require a narrower holding position, while others may require a wider holding position. By arranging adjacent second holding position 1201 and third holding position 1202 on one side, more people can be accommodated.

[0057] In some embodiments, as Figure 1 shown, the overhead door bar 1 further includes two detachable connection components 14 respectively corresponding to the two door lintels hooks 102; the detachable connection components 14 are used to detachably connect the door lintels hooks 102 to the lower crossbar 11. When viewed from the left or right side of the overhead door bar 1, during use, the overall shape of the overhead door bar 1 is similar to a T shape and occupies a relatively large space. By combining the detachable connection components 14 and the rotatable pull-up handle 101, the occupied space can be effectively saved, especially during the stages of cargo transportation or home storage. Specifically, when it is necessary to fold the overhead door bar 1, with the aid of the detachable connection components 14, the fastening state between the door lintels hooks 102 and the lower crossbar 11 can be released. The door lintels hooks 102 can be adjusted in position, for example, placed in a posture parallel to the upper crossbar 12, and the pull-up handle 101 is rotated to make it substantially coplanar with the lower crossbar 11 and the upper crossbar 12. Thus, the overhead door bar 1 in a T-like shape during use can be changed into a flat shape, which is convenient for transportation and storage.

[0058] 4. Regarding the composition of the detachable connection components 14

[0059] 4.1 In some embodiments, as Figures 7 to 10 shown, the composition of the detachable connection components 14 can adopt Solution 1:

[0060] It includes a sleeve 140 and a bolt 141; the sleeve 140 is fixed to the end of the lintel hook 102 away from the lintel, and the sleeve 140 is sleeved on the lower crossbar 11; the bolt 141 is used to fixedly connect the sleeve 140 and the lower crossbar 11. With the foregoing structure, disassembly and assembly are convenient. When carrying out the installation work, the lower crossbar 11 can be first inserted into the sleeve 140, and the sleeve 140 is slid to the corresponding fastening position. After reaching the fastening position, the bolt 141 is inserted into the sleeve 140 and the lower crossbar 11, and then the sleeve 140 and the lower crossbar 11 can be fixedly connected. The installation steps are short and easy to operate.

[0061] 4.1.1 On the basis of the solution provided in 4.1, further, in some embodiments, the connection method of the bolt 141 can adopt Solution 1:

[0062] Both the head and the tail of the bolt 141 are exposed, that is, they do not penetrate into the lintel hook 102. The detachable connection assembly 14 further includes a nut (not shown in the figure) adapted to the bolt 141. With this structure, since both the head and the tail of the bolt 141 are exposed, it is convenient to disassemble and assemble the nut.

[0063] 4.1.2 On the basis of the solution provided in 4.1, further, in some embodiments, the connection method of the bolt 141 can adopt Solution 2:

[0064] The lintel hook 102 is a pipe fitting; the bolt 141 penetrates into the sleeve 140, the lower crossbar 11 and the lintel hook 102, and the tail end of the bolt 141 is located inside the lintel hook 102, and the middle section is hidden in the sleeve 140 and the lower crossbar 11, and only the head is exposed, making the overall product more compact and beautiful.

[0065] Further, on the basis of the solution provided in 4.1.1 or the solution provided in 4.1.2, regarding the setting of the thread and the through hole, it can adopt:

[0066] On the side of the sleeve 140 penetrated by the bolt 141, the side of the lower crossbar 11 penetrated by the bolt 141, and the side of the lower crossbar 11 penetrated by the bolt 141, through holes without threads are provided, and only the side of the sleeve 140 penetrated by the bolt 141 is provided with a threaded section. In this case, as Figure 7 shown, since it is necessary to ensure that the sleeve 140 can be smoothly sleeved on the lower crossbar 11, an installation space needs to be reserved between the two, that is, the area A1 filled with reticulations; as Figure 8 shown, during the process of tightening the bolt 141, the sleeve 140 will be pushed and finally form an internal space with unequal sizes on both sides, that is, the area A2 filled with reticulations; as Figure 9As shown, when the user does a chin-up, the lintel hook 102 is firmly fixed on the lintel. The horizontal bar 1 on the door bears the downward pulling force as a whole. The lower crossbar 11 has a tendency to bend downward, that is, the lower crossbar 11 will enter the area A3 filled with reticulations and finally fit against the lower left side of the inner side of the sleeve 140. With this structure, the lower crossbar 11 has space to bend downward, and the force can be transmitted to the sleeve 140, enabling the lower crossbar 11 and the sleeve 140 to bear the force together.

[0067] 4.2 In some embodiments, as Figure 10 shown, the detachable connection assembly 14 can be composed according to Scheme 2:

[0068] Taking the side of the lower crossbar 11 facing the lintel hook 102 and fixed thereto as the rear side, and the back of the rear side as the front side; the detachable connection assembly 14 includes a bolt 141, a front annular piece 142 that fits the front side, and a rear annular piece 143 that fits the rear side; the lintel hook 102 is a pipe fitting. The bolt 141 passes through the front annular piece 142, the lower crossbar 11, the rear annular piece 143, and the lintel hook 102, and fixedly connects the front annular piece 142, the lower crossbar 11, and the rear annular piece 143; along the user's ascending direction, there is a gap 1420 between the lower ends of the front annular piece 142 and the rear annular piece 143; the gap 1420 is used for the front annular piece 142 to offset downward to abut against the rear annular piece 143 when bearing the user's downward pulling force, so as to achieve joint force bearing. Compared with Scheme 1 of the detachable connection assembly 14, especially the scheme with the thread and through-hole arrangement, after the horizontal bar 1 on the door is stressed, the lower crossbar 11 will enter the area A3 filled with reticulations, and there will be non-fitting parts between the sleeve 140 and the lower crossbar 11. When there are forces in other directions, there will be shaking and noise. In Scheme 2 adopted in this embodiment, when the horizontal bar 1 on the door is stressed, the front annular piece 142 will have a slight downward offset and abut against the rear annular piece 143. Here, not only the bolt 141 can bear the corresponding force, but also due to the existence of the gap 1420, the front annular piece 142 and the rear annular piece 143 can also bear the corresponding force, improving the overall force-bearing capacity. And because the offset direction and offset amount of the front annular piece 142 are relatively determined, the shaking and noise during the fitting process can be effectively reduced.

[0069] In some embodiments, as Figure 10 shown, the fixation of the front annular piece 142 to the front side of the lower crossbar 11 includes, but is not limited to, welding, bolts and nuts. The specific welding method can be: the inner arc surface of the front annular piece 142 is directly attached to the outer arc surface of the lower crossbar 11, and the periphery (i.e., the outer edge) of the front annular piece 142 is welded and fixed to the lower crossbar 11.

[0070] In some embodiments, as Figure 1As shown, the lintel hook 102 is a telescopic hook, adopting a telescopic structure, which can adjust the length of the lintel hook 102 to adapt to door frames of different thicknesses and save space during storage. Among them, the telescopic structure of the lintel hook 102 is an existing structure. For example Figure 1 as shown, the threaded pin 15 and multiple pin holes 1020 can also be the telescopic structure of a clothes drying rod (not shown in the figure).

[0071] In some embodiments, such as Figure 1 as shown, one end of the connecting rod 101 facing the lower crossbar 11 is fixedly provided with a widened connecting piece 16; the widened connecting piece 16 fits and is fixed to the lower crossbar 11. If the end of the connecting rod 101 is directly connected to the lower crossbar 11, since the end of the connecting rod 101 is relatively small, the connection surface / contact surface between the two is small, and the load-bearing capacity is relatively limited. After adding the widened connecting piece 16, the connection surface / contact surface can be increased, and the load-bearing capacity can be improved. In addition, the fixing method of the widened connecting piece 16 to the lower crossbar 11 includes but is not limited to welding, bolts and nuts.

[0072] In some embodiments, such as Figure 1 as shown, a connecting ring 17 is installed in the middle of the upper crossbar 12, and the connecting ring 17 is used to connect a stretching fitness appliance (not shown in the figure). First, the installation method of the connecting ring 17 to the upper crossbar 12 includes but is not limited to fixed and rotational connections. The fixed method can be welding or bolts and nuts, and the rotational connection can be a sleeve. Second, the stretching fitness appliance refers to a type of appliance that users exercise by stretching, including but not limited to elastic bands, tension bands, and resistance bands. These can only contain a band body or can be provided with handles on the band body. Third, adding the connecting ring 17 can increase the stretching training options. Users can tie the stretching fitness appliance to the connecting ring 17, or just wind it without tying it, that is, the middle part of the stretching fitness appliance is wound around the connecting ring 17, one end passes through the connecting ring 17 downward, and the other end passes through the connecting ring 17 upward. Thus, users can use the connecting ring 17 as a fixed point and pull outward for exercise.

[0073] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
