Description
Technical Field
[0001] The utility model relates to the technical field of treadmills, and particularly to an alignment structure for a treadmill running board that is folded, unfolded, and flattened so that adjacent running boards are flush with each other after folding. Background Art
[0002] To facilitate transportation and reduce the storage space at home, many treadmills in the prior art are designed with a foldable structure for the front and rear running boards. For example, folding mechanism bodies, or commonly known as hinges, are symmetrically arranged on the side frames of the front and rear running boards. The front and rear running boards of the front and rear running boards are fixed within the side frames of the front and rear running boards through their respective cross bars. The front and rear running boards can be rotated 180° through the folding mechanism bodies on both sides to be folded parallel to each other. When running is required, they are rotated 180° in the reverse direction to expand the front and rear running boards into a flat running state.
[0003] However, the above-mentioned foldable treadmills in the prior art still have the following common deficiencies: 1. It is very difficult to keep the top surfaces of the front and rear running boards after unfolding on the same plane, and it is also very difficult to ensure that there is no gap between the front and rear running boards. As a result, there is a sense of drop and unevenness at the joint of the front and rear running boards. In order to improve the good foot feeling and experience of the runner, the general treatment method is to lay a layer of flexible material layer on the front running board and the rear running board as a whole to eliminate the sense of drop and unevenness. However, if it is relatively thin, it is difficult to completely eliminate it. If it is relatively thick, it is soft and brings a negative effect to the authenticity of running, and makes the manufacturing process relatively complex and relatively increases the material cost. Moreover, multiple folds and unfoldings also greatly reduce the effect and service life of the flexible material layer. 2. It is also very difficult to keep the top surfaces of the front two side frames and the rear two side frames after unfolding on the same plane. Generally, there is a gap between one end of the outer movable part of the two folding mechanism bodies and one of the front and rear side frames, and there is generally also a gap between the movable part and the fixed part of the two folding mechanism bodies, which directly affects the firmness, stability, and reliability of the connection of the front and rear side frames, and also more or less affects the good experience of the runner. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an alignment structure for a treadmill running board that is folded, unfolded, and flattened so that adjacent running boards are flush with each other after folding, and the top surfaces of adjacent running boards are on the same plane and there is no gap between adjacent running boards.
[0005] The technical solution of the utility model is to provide an alignment structure for a treadmill running board that is folded, unfolded, and flattened so that adjacent running boards are flush with each other after folding. At the joint of the first running board of the first running platform and the second running board of the second running platform, there is a structure that makes the adjacent running boards on the same plane and in contact with each other when the adjacent running platforms are unfolded: at least one female part with a first groove is fixed on the first running board, and at least one male part with a first protrusion that matches the shape of the first groove of the female part and slides to contact and makes the top surfaces of the first running board and the second running board on the same plane is fixed on the second running board.
[0006] After adopting the above structure, the treadmill platform of the utility model is unfolded after being folded to make the adjacent treadmills flush with the alignment structure, which has the following advantages: when the folded treadmill is unfolded and flattened, the first groove of the female part of the first running board, such as the front running board, and the first protrusion of the male part of the second running board, such as the rear running board, naturally fit together and slide against each other, that is, automatically guide and align, so that the top surface of the first running board and the top surface of the second running board are maintained in the same plane, such as the same horizontal plane, and the adjacent first running board and second running board, such as the front running board and the rear running board, have a strong sense of unity, that is, a strong sense of overallness, which completely eliminates the sense of drop and unevenness at the junction of the two adjacent running boards, such as the front running board and the rear running board in the prior art, improves the runner's good foot feel and good experience, and also improves the sense of reality of the running board with feet on the ground; makes the manufacturing process relatively simple; and relatively saves material costs; and can maintain the above good technical effects for a long time and greatly extend the service life of the treadmill.
[0007] Further, the female component is a female strip, and the male component is a male strip; the female component is arranged in the middle of the width direction of the first running board and extends to both ends of the width direction of the first running board, or multiple female components are arranged at intervals along the width direction and on the same line; the male component is arranged in the middle of the width direction of the second running board and extends to both ends of the width direction of the second running board, or multiple male components are arranged at intervals along the width direction and on the same line. After adopting the above structure, the cross-sections of the two remain reasonably narrow, making the guidance of the first protrusion and the first groove more flexible and accurate, making the matching and sticking of the two faster and more reliable, and the alignment structure will not interfere with the two frames described below.
[0008] Furthermore, the first crossbar of the first running board at the shelving joint is fixed to the two first frames, the female strip is fixed to the first crossbar via a plurality of first longitudinal bars, and the outer side of the female strip is in the same vertical plane as the outer end of the first running board; the second crossbar of the second running board at the shelving joint is fixed to the two second frames, the male strip is fixed to the second crossbar via a plurality of second longitudinal bars, and the outer side of the male strip is convex to the outer end of the second running board. With the above structure, the connection between the joint of the first running board, such as the front running board, and the second running board, such as the rear running board, and the respective two frames is more firmly and reliably connected, and the male strip and the female strip are more firmly, more reliably and more stably connected, further ensuring the technical effect of making the guidance of the first protrusion and the first groove more flexible and more accurate, and making the matching and sticking of the two faster and more reliable.
[0009] Furthermore, the first groove matches the first protrusion in shape, and the first groove and the first protrusion are in surface contact. With the above structure, the technical effect of making the guidance of the first protrusion and the first groove more flexible and more accurate, and making the matching and sticking of the two faster and more reliable is further ensured.
[0010] Furthermore, the first groove is a V-shaped groove with an opening facing the first protrusion, and the first protrusion is a V-shaped protrusion with a convex tip facing the first groove. After adopting the above structure, the first groove is a specific V-shaped groove, and the first protrusion is a specific V-shaped protrusion. Compared with the first grooves and first protrusions of other specific shapes, each has its own advantages and disadvantages, and both can achieve the technical effects of guiding, resisting, and making the top surfaces of the first running board and the second running board on the same plane. Specifically, the V-shaped groove and the V-shaped protrusion have relatively better guiding properties compared with the first grooves and first protrusions of other specific shapes. The two are relatively quickly attached to each other, and the accuracy of the top surfaces of the first running board and the second running board on the same plane is relatively high.
[0011] Furthermore, the first groove is a U-shaped groove with an opening facing the first protrusion, and the first protrusion is a U-shaped protrusion with a convex arc surface facing the first groove. After adopting the above structure, the contact surface between the U-shaped groove and the U-shaped protrusion is relatively larger than that between the V-shaped groove and the V-shaped protrusion.
[0012] Furthermore, the first groove is a semi-circular groove with an opening facing the first protrusion, and the first protrusion is a semi-circular protrusion with a semi-circular convex surface facing the first groove. After adopting the above structure, the contact surface between the semi-circular groove and the semi-circular protrusion is relatively larger than that between the V-shaped groove and the V-shaped protrusion.
[0013] Furthermore, each folding mechanism body includes a first fixed clamping plate fixed to the first running platform and a second fixed clamping plate fixed to the second running platform; it also includes a first connecting plate located on the outside and fixed to the first fixed clamping plate and a second connecting plate located on the inside and fixed to the second running platform. There is a first arc-shaped through hole on the first connecting plate, and a second arc-shaped through hole on the second connecting plate; it also includes a sliding plate located between the first connecting plate and the second connecting plate. At least one first pin is fixed to the outside of the sliding plate and is slidably matched with the first arc-shaped through hole, and at least one second pin is fixed to the inside of the sliding plate and is slidably matched with the second arc-shaped through hole. Both ends of the sliding plate have a second protrusion and a third protrusion respectively. After adopting the above structure, the components of the folding mechanism body are relatively few, the structure is relatively simple, the volume of the folding mechanism itself is relatively small, the sliding between the slider and the two connecting blocks is labor-saving and reliable, the guiding property of the pin sliding in its respective arc-shaped through hole is good, and the folding or opening of the first running board and the second running board is flexible, stable and reliable.
[0014] Furthermore, the inner end of the first fixed clamping plate is fixed to the first frame, and the outer end of the first fixed clamping plate has a second groove that matches the shape of the second protrusion and slides to abut, so that the top surfaces of the butted first frame and the second frame are on the same plane; the inner end of the second fixed clamping plate is fixed to the second frame, and the outer end of the second fixed clamping plate has a third groove that matches the shape of the third protrusion and slides to abut, so that the top surfaces of the butted first frame and the second frame are on the same plane. After adopting the above structure, when the folded running platform is unfolded and flattened, the second grooves of the first fixed clamping plates of the two first frames, such as the two front frames, naturally coincide with the second protrusions at one end of the sliding plate of the folding mechanism body and slide to abut against each other, and the third grooves of the second fixed clamping plates naturally coincide with the third protrusions at the other end of the sliding plate of the folding mechanism body and slide to abut against each other, that is, they are automatically guided and aligned, so that the top surfaces of the two first frames, such as the two front frames, and the top surfaces of the two second frames, such as the two rear frames, are kept on the same plane and abut against each other. In other words, when unfolded, the top surface of one first frame, such as one front frame, and the top surface of one second frame, such as one rear frame, are on the same plane, and the top surface of the other first frame, such as the other front frame, and the top surface of the other second frame, such as the other rear frame, are on the same plane and abut against each other. This further improves the good experience of the runner and greatly improves the firmness, stability and reliability of the connection between the two first frames and the two second frames.

[0027] The following further describes the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these detailed implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the following detailed implementation manners of the present utility model can be combined with each other as long as they do not conflict with each other.
[0028] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ,Figure 6 , Figure 7 and Figure 8 as shown.
[0029] For the convenience of transportation and to reduce the storage space at home, the treadmill 1 can be designed such that the first running board 11 (such as the front running board) and the second running board 12 (such as the rear running board) are of a foldable structure. The first side frames 111 (such as the front side frames) on both sides of the first running board 11 and the second side frames 121 (such as the rear side frames) on both sides of the second running board 12 are hinged to each other through a folding mechanism body 3, and the folding mechanism body 3 is also called a hinge, that is, folding mechanism bodies 3 are symmetrically provided on the side frames of both the first running board 11 and the second running board 12. The first running board 112 (such as the front running board) of the first running board 11 is fixed within the two first side frames 111 (such as the front side frames) through a first cross bar 113, and the second running board 122 (such as the rear running board) of the second running board 12 is fixed within the two second side frames 121 (such as the rear side frames) through a second cross bar 123. A running belt 14 or a running belt is covered outside the first running board 112 (such as the front running board) and the second running board 122 (such as the rear running board). The first running board 11 (such as the front running board) and the second running board 12 (such as the rear running board) can be rotated 180° through the folding mechanism bodies 3 on both sides to be folded parallel to each other, and when running is required, they are rotated 180° in the reverse direction to unfold and flatten the first running board 11 (such as the front running board) and the second running board 12 (such as the rear running board), or to be laid flat in a running state.
[0030] The invention points of the alignment structure of the treadmill running board of the present utility model, which makes the adjacent running boards flush after unfolding and flattening after folding, are as follows.
[0031] At the joint of the first running board 112 of the first running board 11 and the second running board 122 of the second running board 12, there is a structure for making the adjacent running boards, that is, the first running board 112 and the second running board 122, be in the same plane and abut against each other when the adjacent running boards are unfolded and flattened: At least one female member with a first groove (such as the V-shaped groove 212 described below), that is, a female strip board 21, is fixed on the first running board 112, and at least one male member with a first protrusion (such as the V-shaped protrusion 222 described below), that is, a male strip board 22, which is matched with the shape of the first groove (such as the V-shaped groove 212) of the female member (such as the female strip board 21) and slides to abut against each other (that is, the two abut against each other), and makes the top surfaces of the first running board 112 and the second running board 122 be in the same plane, is fixed on the second running board 122. Here, the adjacent running boards, that is, the first running board 11 and the second running board 12 being unfolded and flattened can be understood as unfolding and flattening after folding. The structure for making the adjacent running boards be in the same plane and abut against each other described in this paragraph can be simply referred to as the running board leveling and abutting structure 2.
[0032] The mother part mentioned above may be a mother strip board 21, and the male part may be a male strip board 22. The mother part, such as the mother strip board 21, is arranged in the middle of the first running board 112 in the width direction and extends towards both ends of the first running board 112 in the width direction, or multiple mother parts, such as mother strip boards 21, are arranged at intervals in the width direction and are on the same straight line. The male part, such as the male strip board 22, is arranged in the middle of the second running board 122 in the width direction and extends towards both ends of the second running board 122 in the width direction, or multiple male parts, such as male strip boards 22, are arranged at intervals in the width direction and are on the same straight line.
[0033] At the shelving joint, the first cross bar 113 of the first running board 112 is fixed to two first side frames 111. The mother strip board 21 is fixed to the first cross bar 113 by multiple, such as three, first longitudinal bars 114. See Figure 1 and Figure 2 , the outer side surface 211 of the mother strip board is on the same vertical plane as the outer end surface 1121 of the first running board; at the shelving joint, the second cross bar 123 of the second running board 122 is fixed to two second side frames 121. The male strip board 22 is fixed to the second cross bar 123 by multiple, such as three, second longitudinal bars 124. The outer side surface 221 of the male strip board protrudes from the outer end surface 1221 of the second running board. The cross bar can be called a cross beam, and the longitudinal bar can be called a longitudinal beam.
[0034] The ends of multiple, such as three, first longitudinal bars 114 fixed to the inner convex surface 213 of the mother strip board may be inner concave surfaces 1141 that match the inner convex surface 213 of the mother strip board, making their fixation more stable and reliable.
[0035] The first groove matches the shape of the first protrusion, and the first groove and the first protrusion are in surface contact:
[0036] The first groove may be a V-shaped groove 212 with an opening facing the first protrusion, and the first protrusion may be a V-shaped protrusion 222 with a convex tip facing the first groove, such as the V-shaped groove 212.
[0037] The first groove may also be a U-shaped groove with an opening facing the first protrusion, and the first protrusion may also be a U-shaped protrusion with a convex arc surface facing the first groove, such as the U-shaped groove.
[0038] The first groove may also be a semi-circular groove with an opening facing the first protrusion, and the first protrusion may also be a semi-circular protrusion with a semi-circular convex surface facing the first groove, such as the semi-circular groove.
[0039] The following changes are allowed for the first groove and the first protrusion:
[0040] The first groove may also be a W-shaped groove with an opening facing the first protrusion, and the first protrusion may also be a W-shaped protrusion with two convex tips facing the first groove, such as the W-shaped groove, etc.
[0041] The shape of the first groove and the first protrusion may not match either, that is, the first groove and the first protrusion may also be in line contact. For example, the first groove is a V-shaped groove, and the first protrusion is an arc-shaped protrusion, such as a U-shaped protrusion or a semi-circular protrusion, etc.
[0042] Of course, the effect of this change is not as good as that of the structure before the above changes. That is, the present utility model preferably has the first groove and the first protrusion matching in shape, and preferably the first groove and the first protrusion are in surface contact. The first groove is preferably a V-shaped groove 212, and the matching first protrusion is preferably a V-shaped protrusion 222; the first groove is preferably a U-shaped groove, and the matching first protrusion is preferably a U-shaped protrusion; the first groove is preferably a semi-circular groove, and the matching first protrusion is preferably a semi-circular protrusion.
