Technical Field
[0001] The utility model relates to the field of bicycle hangers, and more particularly to a foldable self-holding wheel type bicycle hanger. Background Art
[0002] As a green and environmentally friendly means of transportation, bicycles are powered by pedals and are deeply loved by the public. More and more people use bicycles as fitness equipment for cycling exercises. When bicycles are not in use, people use bicycle racks to hang them on the wall to save space.
[0003] Existing bicycle racks can accommodate bicycles with different handlebar heights, but the bicycle tires are exposed and easily worn or squeezed, and the bicycles are not fixed and can easily be bumped and fall to the ground. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a foldable self-holding wheel bicycle hanger, which can protect bicycle tires, adapt to wheels of different sizes, and will not fall off.
[0005] In order to solve the above problems, the present invention adopts the following technical solutions.
[0006] A foldable self-holding wheel bicycle rack, comprising a U-shaped upper wall stop, a U-shaped bottom stop, and an adjustable positioning piece;
[0007] The U-shaped upper wall support is fixed vertically on the wall;
[0008] A limited-angle rotation connection is formed between one end of the U-shaped bottom rail and the lower end of the U-shaped upper wall rail; the U-shaped bottom rail is provided with a wheel groove extending through at least a portion of its bottom surface for receiving a bicycle tire;
[0009] The adjustable positioning part includes a front positioning part and a kick-up foot; the front positioning part is located on the side of the wheel groove close to the wall and is fixed when in use; the kick-up foot is located on the side of the wheel groove away from the wall and has a rotational connection with the end of the U-shaped bottom stop away from the wall with a limited angle; the front positioning part and the kick-up foot respectively abut the same tire at the front and rear to support the tire and limit its downward movement tendency.
[0010] Furthermore, the front positioning member includes a tire baffle; the tire baffle is fixedly connected to the bottom end of the U-shaped bottom block; the tire baffle is arranged at an angle, and the inclination direction is in the direction away from the U-shaped bottom block and extends in the direction of the wheel groove, so that when the bicycle is hung, it is located under the bicycle tire to support the bicycle tire.
[0011] Furthermore, the front positioning member also includes a positioning wheel; a plurality of positioning holes are provided on both sides of the U-shaped bottom block, and the positioning holes on both sides are symmetrical about the center of the positioning wheel. Both ends of the positioning wheel are slidably connected with a fixing ring, and the two fixing rings are respectively clamped in one of the pairs of positioning holes. The positioning hole is located at one end close to the U-shaped upper wall block, and the adjacent positioning holes on the same side are connected to each other through a slide running through the side end of the U-shaped bottom block, and the length of the wheel groove is less than the length of the U-shaped bottom block; the positioning wheel is detachably mounted on the upper side of the tire baffle; the diameter of the positioning hole is greater than the width of the slide.
[0012] Furthermore, the U-shaped bottom rail has a rotation range of 90 degrees from horizontal to vertical upward.
[0013] Furthermore, the kickstand includes a kickstand body and two tire side baffles, which are respectively fixedly connected to both sides of the kickstand body to limit the horizontal movement of the tire; the two tire side baffles are both located on the inner side of the U-shaped bottom block, and are both independently rotatably connected to the end of the U-shaped bottom block away from the wall; the rotation axes of the two tire side baffles are concentric to release space for the kickstand to embed the tire.
[0014] Furthermore, the angle formed by the upper and lower ends of the leg body is an obtuse angle, and the lower end of the leg body adopts an arc design. When the tire is hung, the tire is protected by two tire side guard plates, and the arc surface of the lower end of the leg body can be tangent to the tire surface.
[0015] Furthermore, the supporting component of the tilted leg is a sheet-like structure, and the tire baffle is a sheet-like structure, so as to increase the contact area with the bicycle tire.
[0016] Furthermore, the kick leg is at a first flip angle in the unfolded state, at which time the supporting part of the kick leg is located outside the wheel groove and is in an outwardly extended state to guide the wheel into the supporting part; the kick leg is at a second flip angle in the stowed state, at which time the supporting part of the kick leg is at least partially folded and arranged in the wheel groove; during the loading process of the kick leg, the supporting part of the kick leg abuts against the wheel at least two places so that it can be driven by it, and has a tendency to flip into the wheel groove with the tire, so that the kick leg has the ability to rotate freely with the tire within the first flip angle and the second flip angle range.
[0017] Furthermore, the center of gravity of the tilting leg is not located on the rotation axis of the tilting leg and the U-shaped bottom rail, so that the tilting leg always has a tendency to rotate toward the first flip angle or the second flip angle in a free state.
[0018] Furthermore, limit protrusions are provided on both sides of the inner walls of the wheel groove away from the end of the wall; the limit protrusions are located within the rotation range of the leg, so that when the leg is at the first flip angle and the second flip angle, the limit protrusions abut against the outer end surface of the leg to interfere and limit the forward and / or reverse rotation of the leg.
[0019] Compared with the prior art, the advantages of the present invention are:
[0020] (1) This solution can realize the folding of the bicycle hanger through the rotation connection of the U-shaped upper wall bracket and the U-shaped bottom bracket, so that a large space can be saved when the bicycle hanger is not in use.
[0021] (2) This solution can protect bicycle tires and prevent them from being worn or squeezed by using the two sides of the U-shaped bottom bar, the arc design at the bottom of the footrest, the arc design of the contact surface between the positioning wheel and the tire, and the tire side baffle. At the same time, the footrest body and the tire baffle are both sheet-shaped. When the bicycle is hung, the tire will produce a certain elastic deformation under the influence of gravity. The sheet-shaped footrest body and tire baffle can increase the contact area with the tire surface, reduce the effect of pressure, and avoid marks on the tire surface caused by long-term hanging.
[0022] (3) This solution can fix the bicycle tire in the wheel groove through the mutual cooperation of the tire baffle, the wheel groove, the positioning wheel and the lifting foot, and the bicycle will not fall off.
[0023] (4) This solution uses a positioning wheel that can slide in the slide and rotate with its legs connected to one end of the U-shaped bottom gear, so that the bicycle rack can adapt to bicycles of different tire sizes. Bicycles of different tire sizes can be hung on it, and the scope of use is wider.
[0024] (5) This solution designs the kickstand to be able to form a rotational connection with the bottom gear at a limited angle, so that the kickstand can become a guiding component in the unfolded state, guiding the wheel to enter the kickstand for positioning; and during the loading process, the tire will abut against the bent kickstand body and drive the kickstand to flip inward, and finally to the second flipping angle, without the need for manual driving of the kickstand to flip, and the wheel can enter accurately and quickly; the kickstand will not rotate indefinitely, but will stop at the position required by the user.
[0025] (6) In this solution, the center of gravity of the leg is eccentric, so that the leg will automatically maintain the first flip angle when it is unfolded, and will automatically rotate to the second flip angle during the loading process, and finally maintain the second flip angle, without the need for manual flipping, which is easy and labor-saving.
[0026] (7) In this solution, the two sides of the footrest and the bottom stop are independently connected by rivets to achieve rotation. Compared with the existing method of using a shaft to achieve rotation connection, the space inside the footrest can be completely released, effectively avoiding the problem that the tire cannot fit and abut against the footrest body due to interference from the shaft.

[0037] Example 1:
[0038] See also Figure 1-8 The foldable bicycle rack with self-holding wheels comprises a U-shaped upper wall bracket 1, a U-shaped bottom bracket 2, a leg 3 and a positioning wheel 4; the U-shaped upper wall bracket 1 is fixedly mounted on the wall, one end of the U-shaped bottom bracket 2 is rotatably connected to the lower end of the U-shaped upper wall bracket 1, and the other end of the U-shaped bottom bracket 2 is rotatably connected to the middle end of the leg 3; a plurality of positioning holes 21 are opened on both sides of the U-shaped bottom bracket 2, and the positioning holes 21 on both sides are symmetrical about the center of the positioning wheel 4, and both ends of the positioning wheel 4 are slidably connected with a fixing ring 41, and the two fixing rings 41 are respectively clamped in one of the pairs of positioning holes 21, and the positioning The hole 21 is located at one end close to the U-shaped upper wall block 1, and the adjacent positioning holes 21 on the same side are connected to each other through a slide 24 that passes through the side end of the bottom block 2. The bottom end of the U-shaped bottom block 2 is fixedly connected to a tire baffle 22, and the tire baffle 22 is located on the lower side of the positioning wheel 4. The bottom end of the U-shaped bottom block 2 is provided with a penetrating wheel release groove 23, and the length of the wheel release groove 23 is less than the length of the U-shaped bottom block 2. The tire baffle 22 is oriented obliquely downward and extends in the direction of the wheel release groove 23; it can protect bicycle tires, adapt to wheels of different sizes, and the bicycle will not fall.
[0039] The U-shaped bottom rail 2 has a rotation range of 90 degrees from horizontal to vertical; the bicycle rack can be folded, so that the bicycle rack can save a large amount of space.
[0040] The footrest 3 includes a footrest body 31 and two tire side fenders 32. The two tire side fenders 32 are fixedly connected to both sides of the footrest body 31. The two tire side fenders 32 are both located on the inner side of the bottom block 2 and are rotatably connected to the end of the bottom block 2 away from the wall. They can block the tires of the bicycle and protect the tires of the bicycle to prevent damage to the tires.
[0041] The diameter of the positioning hole 21 is larger than the width of the slide 24; the two ends of the positioning wheel 4 can be clamped in the positioning hole 21 and cannot move, which can block the bicycle tire and prevent the bicycle with a smaller tire from falling.
[0042] When the mounted tire cannot be blocked by the tire baffle 22, the positioning wheel 4 can slide in the slideway 24 until it contacts the tire, and the contact surface adopts an arc design that can match the tire; this can protect the bicycle tire and prevent the bicycle tire from being worn. The positioning wheel 4 can also better match the tire to prevent the bicycle from falling.
[0043] The angle formed by the upper and lower ends of the foot body 31 is an obtuse angle, and the lower end of the foot body 31 adopts an arc design. When the tire is hung, the tire is protected by the two tire side guards 32, and the arc surface of the lower end of the foot body 31 can be tangent to the tire surface; it can protect the bicycle tire and can also adapt to wheels of different sizes.
[0044] Working principle: When you need to use a bicycle rack, Figure 1 As shown, since the rotation range of the U-shaped bottom rail 2 is from horizontal to vertical upward, the U-shaped bottom rail 2 is swung away from the wall. Because of the gravity of the U-shaped bottom rail 2, the U-shaped bottom rail 2 is in a horizontal state, and the front tire of the bicycle can be placed in the wheel groove 23, as shown in FIG. Figure 7 shown.
[0045] When a bicycle with a large tire is mounted, the tire baffle 22 blocks one end of the front wheel of the bicycle, and the lower end of the leg body 31 blocks the other end of the front wheel of the bicycle. Due to the weight of the bicycle, the lower end of the leg body 31 is pressed, so that the leg 3 is Figure 1 The bicycle is placed vertically with the handlebars facing outwards, so that the bicycle can be fixed on the bicycle rack because the tire baffle 22 and the cross leg 3 block the direction opposite to gravity and will not fall off the road.
[0046] When attaching a bicycle with small tires, such as Figure 2 As shown, the tire baffle 22 cannot block one end of the front wheel of the bicycle, which will cause the front wheel of the bicycle to fall. (Because both ends of the positioning wheel 4 are slidably connected with fixing rings 41, the two fixing rings 41 are respectively clamped in the positioning holes 21 opened on both sides of the U-shaped bottom gear 2, and the adjacent positioning holes 21 on the same side are connected to each other through the slide 24 running through the side end of the U-shaped bottom gear 2), so the two fixing rings 41 can be slid out from both ends of the positioning wheel 4, so that the positioning wheel 4 slides in the slide 24. At this time, the positioning wheel 4 can be moved in the slide 24 to a direction away from the wall. Move it in the direction until the positioning wheel 4 can touch one end of the front wheel of the bicycle and when it can be determined that the front wheel of the bicycle cannot fall off, the two fixed rings 41 taken out are installed on the two ends of the positioning wheel 4 so that the two fixed rings 41 are both engaged in the two positioning holes 21 away from the wall, thereby preventing the positioning wheel 4 from sliding in the slide 24, so that the positioning wheel 4 can block the front wheel of the bicycle and prevent it from falling off, and can adapt to wheels of different sizes. The U-shaped bottom stop 2, tire baffle 22, foot 3 and positioning wheel 4 can protect the bicycle tire.
[0047] When the bicycle rack is not required, such as Figure 3 As shown, the U-shaped bottom rail 2 can be rotated upward to be in a vertical state, and the legs 3 are also in a vertical state. In this way, folding will not take up a large space and can save space.
[0048] Preferably, the two tire side baffles (32) are both located on the inner side of the U-shaped bottom baffle (2), and are both independently rotatably connected to the end of the U-shaped bottom baffle (2) away from the wall through rivets; the rotation axes of the two tire side baffles (32) are concentric to release space for the foot (3) to embed the tire.
[0049] Preferably, the supporting part of the footrest (3) is a sheet-like structure, and the tire baffle (22) is a sheet-like structure, so as to increase the contact area with the bicycle tire. When the bicycle is hung, the tire will produce a certain elastic deformation under the influence of gravity. The sheet-like structure of the footrest body 31 and the tire baffle 22 can increase the contact area with the tire surface, reduce the effect of pressure, and avoid marks on the tire surface caused by long-term hanging.
[0050] Preferably, the leg (3) is at a first flip angle in the unfolded state, at which time the supporting part of the leg (3) is located outside the wheel groove (23) and is in an outwardly extended state to guide the wheel into the supporting part; the leg (3) is at a second flip angle in the retracted state, at which time the supporting part of the leg (3) is at least partially folded and arranged in the wheel groove (23); during the loading process of the leg (3), the supporting part of the leg (3) abuts against the wheel at least two places so as to be driven by the wheel and has a tendency to flip into the wheel groove (23) along with the tire, so that the leg (3) has the ability to rotate freely along with the tire within the range of the first flip angle and the second flip angle.
[0051] Specifically, both inner walls of the bottom side plate 21 away from the wall end are provided with limiting protrusions 26; the limiting protrusions 26 are located within the rotation range of the leg 3 so as to abut the outer end surface of the leg 3 when the leg 3 is at the first flip angle and the second flip angle, thereby interfering with and limiting the forward and / or reverse rotation of the leg 3. Specifically, there is a gap between the tire side baffle 32 and the leg body 31 (the portion without the tire side baffle 32); when the leg 3 is at the first flip angle, the limiting protrusions 26 are located within the gap to abut the leg 3 to prevent it from further flipping outward; the tire side baffle 32 is provided with a slide 34 near the rotation axis, and the slide 34 and the limiting protrusion 26 coincide with the rotation path of the limiting protrusion 26 relative to the rotation axis. When the leg 3 is at the second flip angle, the limiting protrusion 26 is located within the slide 34 to abut the leg 3 to prevent it from further flipping inward.
[0052] Preferably, the center of gravity of the leg 3 is not located at the rotation axis between the leg 3 and the U-shaped bottom rail 2. In this embodiment, this means that the length of the portion of the leg body 31 without the tire side guard 32 is shorter than the length of the portion of the leg body 31 with the tire side guard 32. Therefore, the center of the leg 3 is not located at the rotation axis between the leg 3 and the U-shaped bottom rail 2, but is located at the portion of the leg body 31 with the tire side guard 32. This ensures that the leg, in a free state (not affected by the wheel), always has a tendency to rotate toward the first flip angle or the second flip angle (in particular, the leg 3 automatically maintains the first flip angle in the extended state and the second flip angle in the retracted state), thereby automatically maintaining the wheel guiding posture or wheel supporting posture without manual adjustment, which is easy and labor-saving.
