Description

Technical Field

[0001] The utility model relates to a roller skate with a plastic shoe shell and a shoe inner cover, in particular to a roller skate which is easy to put on and take off. Background Art

[0002] Currently, common roller skates generally include a plastic shoe shell, a shoe liner, and a bracket (also called a blade holder or wheel bracket). The shoe liner is constrained within the plastic shoe shell, which is fixed above the bracket. Multiple rollers and brake pads are mounted on the bracket. The plastic shoe shell generally has a sole. The front portion of the sole has bilaterally symmetrical, spaced-apart shoe holes that cover the upper portion. The upper portion is provided with shoe holes for threading shoelaces. The rear portion of the sole is fixed with a leg wrap that provides greater support for the leg. The leg wrap is provided with a plastic adjustment strap for binding. The main way to wear these roller skates with a plastic shoe shell and shoe liner is to tighten the shoelaces at the front of the shoe shell and the adjustment straps at the leg wrap. Because the plastic shoe shell is relatively hard, this type of wearing method requires completely untying the shoelaces before the foot can be inserted into the shoe liner from the outside, making it inconvenient to wear.

[0003] To this end, the applicant has invented a Chinese utility model patent with patent number ZL201520860304.5 (publication number CN205269001U), which discloses a roller skate shell that is easy to put on and take off, including a sole, the front part of the sole has a covering structure that can restrain the front part of the shoe inner cover, and the rear part of the sole is provided with a leggings part; the characteristic is that: the leggings part is rotatably connected to the rear part of the sole and can be flipped backward to open, the rear end of the sole is rotatably connected to a support rod for supporting the leggings part, the upper end of the support rod is provided with a rearwardly protruding positioning button, and the leggings part is provided with a positioning hole that is engaged with the positioning button; when the leggings part is flipped upward and in a covering state, the upper end of the support rod is located on the inner side of the leggings part, and the positioning button on the support rod is stuck in the positioning hole; when the positioning button is disengaged from the positioning hole, the leggings part can be flipped backward to open.

[0004] In order to prop up the leggings, a support rod needs to be set up, and the positioning buttons on the support rod need to be inserted into the positioning holes on the leggings. The support rod and the leggings are both rotatably connected to the rear end of the shoe bottom, and there is a flipping order, which makes the operation very inconvenient. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an easy-to-put-on-and-off roller skate with a more reasonable and compact structure, which enables quick and convenient donning and doffing, in response to the above-mentioned existing technical status. The easy-to-put-on-and-take-off roller skate shell has a leg wrap that can be fully opened backwards. This roller skate shell allows for quick and convenient donning and doffing, and allows the liner to be effectively wrapped in the shell and completely removed from the shell for daily walking use.

[0006] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a pair of roller skates that are easy to put on and take off, including a sole and a leggings part, the front part of the sole is provided with a tongue cover, the left and right sides of the rear part of the sole are provided with upwardly extending mounting walls, and the left and right sides of the leggings are provided with downwardly extending connecting arms; it is characterized in that: an outwardly protruding mounting shaft is fixed on the mounting wall, a through-hole is provided on the connecting arm, the connecting arm is sleeved on the mounting shaft through the through-hole so that the leggings part is rotatably connected to the mounting wall, and an unlockable locking structure is provided between the connecting arm and the mounting shaft on at least one side, the locking structure locks the connecting arm and the mounting shaft together, so that the leggings part is in a vertical wearing state, and when the locking structure is unlocked, the leggings part can be flipped backward and opened relative to the sole of the shoe.

[0007] As a preferred locking structure, the connecting arm is provided with a mounting cavity, the locking structure including a locking button that is movably mounted within the mounting cavity, and the mounting shaft having a locking notch for inserting the locking button. The locking button can be moved into or out of the locking notch. The mounting cavity provides a suitable mounting position for the locking button. When the locking button is inserted into the locking notch on the mounting shaft, the connecting arm and the mounting shaft are locked together. When the locking button is released from the locking notch, the locking button can be flipped backward relative to the sole of the shoe along with the connecting arm.

[0008] Further improvement, the above-mentioned installation shaft includes a first shaft and a second shaft, the first shaft is fixed on the installation wall, the first shaft has an accommodating cavity, the inner end of the second shaft is inserted and constrained in the accommodating cavity so that it can only slide axially within a certain range relative to the first shaft, and a first spring is provided in the accommodating cavity to maintain the outward movement trend of the second shaft, and the locking mouth is provided on the peripheral wall of the second shaft; when the second shaft moves inward relative to the first shaft until the locking mouth is aligned with the locking button, the locking button can be inserted into the locking mouth; when the locking button is out of the locking mouth, the second shaft moves axially outward under the action of the first spring, the locking mouth and the locking button are misaligned, and the locking button cannot be inserted into the locking mouth. This structure makes the locking and unlocking operations between the connecting arm and the mounting wall simpler. When unlocking, it is only necessary to move the locking button to disengage the locking hole. The second shaft moves axially outward under the action of the first spring, the locking hole and the locking button are misaligned, and the locking button cannot be inserted into the locking hole. In this way, the connecting arm can rotate around the axis of the second shaft relative to the mounting wall. When locking, it is only necessary to push the second shaft inward to overcome the elastic force of the first spring and move it inward relative to the first shaft until the locking hole is aligned with the locking button. At this time, the moving locking button can be inserted into the locking hole, completing the locking between the connecting arm and the mounting wall.

[0009] To further ensure that the second shaft can only move axially relative to the first shaft and cannot rotate, the outer end of the first shaft has a guide groove, and the inner end of the second shaft has a guide rib that inserts into the guide groove. The guiding cooperation between the guide rib and the guide groove also makes the movement of the second shaft smoother.

[0010] To facilitate securing the first shaft within the mounting hole, a further improvement is provided in the aforementioned mounting wall, wherein a mounting hole for inserting the first shaft is formed. The first shaft has a plurality of outwardly protruding positioning portions on its periphery, and the wall of the mounting hole is provided with positioning grooves corresponding to the positioning portions. A positioning pin is provided through the rear portion of the first shaft, with both ends of the positioning pin extending through the periphery of the first shaft. The back of the mounting wall is provided with an embedding groove into which the positioning pin extending through the periphery of the first shaft is embedded. The mating of the positioning portion and the positioning groove prevents the first shaft from rotating about its own axis relative to the mounting hole, thereby achieving axial positioning. The bottom end of the positioning groove is sealed, preventing the first shaft from further extending through the aforementioned mounting hole, thus achieving rearward positioning. Furthermore, the positioning pin cooperates with the embedding groove on the back of the connecting arm to prevent the first shaft from moving forward out of the mounting hole, ultimately achieving positioning.

[0011] To facilitate locking the mounting arm and mounting wall, a second spring is installed within the mounting cavity. This second spring acts on the locking knob, keeping it positioned downward toward the mounting shaft. To lock the mounting arm, the second shaft is pushed inward, overcoming the force of the first spring until the locking notch aligns with the locking knob. At this point, the locking knob, under the action of the second spring, automatically engages the notch, completing the locking process.

[0012] Preferably, the lock button has an insertion portion extending downward and a side-convex push-and-twist portion, wherein the insertion portion is used to be inserted into the lock port, and the push-and-twist portion exposes an installation cavity for the user to push.

[0013] In order to facilitate the formation of the installation cavity, a side cover is fixed to the outer end surface of the connecting arm, and the installation cavity is formed between the side cover and the outer end surface of the connecting arm.

[0014] As a further improvement, the rear ends of the two mounting walls are connected together by an arcuate connecting portion. The mounting wall and the arcuate connecting portion are connected together, which can have a certain restraining effect on the shoe inner cover, and when the leggings rotate to fit the arcuate connecting portion, the leggings are restrained.

[0015] A further improvement is that the front end of the tongue cover is rotatably connected to the front portion of the sole and can be flipped forward to open. A strap structure is provided between the tongue cover and the sole. When the tongue cover is flipped back to cover the upper of the shoe liner, the strap structure can secure the tongue cover to the sole. This allows not only the gaiter portion of the shoe shell to be flipped back and opened, but also the tongue cover that restrains the shoe liner to be flipped forward to open. That is, the gaiter portion and tongue cover can be easily and fully opened in the front-to-back direction, making it more convenient to put the shoe liner in and out.

[0016] Compared with the prior art, the advantages of the present invention are: the leggings are rotatably mounted on the connecting wall of the shoe bottom through the connecting arms thereon. Specifically, the connecting arms are mounted on the mounting shaft through perforations so that the leggings are rotatably connected to the mounting wall, so that the leggings can be flipped backward relative to the rear of the shoe bottom, making it convenient for the shoe inner cover to enter and exit the shoe shell from the rear. At the same time, the shoe inner cover can be completely taken out of the shoe shell, which can not only be used independently as a daily shoe, but also solve the inconvenience of carrying extra shoes. In addition, the locking structure is directly arranged between the connecting arm and the mounting shaft, and no additional components are required to complete the locking. The locking structure locks the connecting arm and the mounting shaft together, so that the leggings are in a vertical wearing state. When the locking structure is unlocked, the leggings can be flipped backward and opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 9 Shown is a preferred embodiment of the present utility model.

[0028] An easy-to-put-on-and-off roller skate comprises a sole 1 and a legging 3. The front portion of the sole 1 is provided with a tongue cover 2. The rear left and right sides of the sole 1 have upwardly extending mounting walls 11. The legging 3 has downwardly extending connecting arms 31 on its left and right sides. The front end of the tongue cover 2 is pivotally connected to the front portion of the sole 1 and can be flipped forward to open. A strap structure (not shown in the drawings) is provided between the tongue cover 2 and the sole 1. When the tongue cover 2 is flipped back to cover the upper of a shoe liner (not shown in the drawings), the strap structure secures the tongue cover 2 to the sole 1. For more information on the above structure, please refer to the background patent.

[0029] The main improvement of the present invention is that: an outward-protruding mounting shaft 5 is fixed on the mounting wall 11, and a through-hole 3a is opened on the connecting arm 31. The connecting arm 31 is sleeved on the mounting shaft 5 through the through-hole 3a so that the leggings 3 are rotatably connected to the mounting wall 11. An unlockable locking structure is provided between the connecting arm 31 and the mounting shaft 5 on at least one side. The locking structure locks the connecting arm 31 and the mounting shaft 5 together, so that the leggings 3 are in a vertical wearing state. When the locking structure is unlocked, the leggings 3 can be flipped backward relative to the sole 1 of the shoe.

[0030] The connecting arm 31 is provided with an installation cavity 3b, and the locking structure includes a lock button 6 that is installed in the installation cavity 3b and can move. The installation shaft 5 is provided with a lock opening 5a for the lock button 6 to be inserted. The lock button 6 can be inserted into or out of the lock opening 5a.

[0031] The mounting shaft 5 includes a first shaft 51 and a second shaft 52. The first shaft 51 is fixed on the mounting wall 11. The mounting wall 11 is provided with a mounting hole 1a for inserting the first shaft 51. The periphery of the first shaft 51 has a plurality of outwardly protruding positioning portions 512. The hole wall of the mounting hole 1a is provided with a positioning groove 1b corresponding to the positioning portion 512. A positioning pin 7 is passed through the rear part of the first shaft 51. Both ends of the positioning pin 7 pass through the peripheral wall of the first shaft 51. The back side of the mounting wall 11 is provided with an embedding groove 1c for the positioning pin 7 passing through the peripheral wall of the first shaft 51 to be embedded.

[0032] The first shaft 51 has a housing cavity 5b. The inner end of the second shaft 52 is inserted and constrained within the housing cavity 5b, allowing only axial sliding relative to the first shaft 51 within a certain range. The outer end of the first shaft 51 has a guide groove 511, and the inner end of the second shaft 52 has a guide rib 521 that inserts into the guide groove. A first spring 4a is installed within the housing cavity 5b to maintain the outward movement of the second shaft 52. A locking notch 5a is provided on the peripheral wall of the second shaft 52. When the second shaft 52 moves inward relative to the first shaft 51 until the locking notch 5a aligns with the locking button 6, the locking button 6 can be inserted into the locking notch 5a. When the locking button 6 is disengaged from the locking notch 5a, the second shaft 52 moves axially outward under the action of the first spring 4a, causing the locking notch 5a to misalign with the locking button 6, preventing the locking button 6 from being inserted into the locking notch 5a.

[0033] A second spring 4b is disposed within the mounting cavity 3b, acting on the locking button 6 to maintain its downward movement toward the mounting axis 5. The locking button 6 comprises a downwardly extending insertion portion 61 and a laterally protruding push-and-twist portion 62. The insertion portion 61 is inserted into the locking opening 5a. The width of the locking opening 5a is greater than that of the insertion portion 61 on the locking button 6. In the locked state, the insertion portion abuts against the sidewall of the locking opening 5a, thereby preventing the legging 3 from flipping backward. This is because the inner shoe cover placed on the sole 1 blocks the legging 3 from further forward rotation. The push-and-twist portion 62 exposes the mounting cavity 3b for the user to push. A side cover 32 is fixed to the outer end surface of the connecting arm 31, forming the mounting cavity 3b between the side cover 32 and the outer end surface of the connecting arm 31.

[0034] The rear ends of the two mounting walls 11 are connected together via an arc-shaped connecting portion 12 .

[0035] The shoe shell mainly consists of three parts: the sole 1, the legging part 3 and the tongue cover 2. It has a strong sense of integrity and good wrapping, which reduces the movements required for putting on and taking off shoes to a minimum and improves the efficiency of putting on and taking off shoes.

[0036] When wearing shoes: Figures 1 to 4 As shown, the shoe inner cover is first put on from the outside, then enters the concave cavity of the sole 1, and then flips the leggings 3 upward. At the same time, the second shaft 52 is pushed inward to overcome the elastic force of the first spring 4a and move inward relative to the first shaft 51 until it is aligned with the locking button 6, and the locking button 6 is automatically inserted into the locking hole 5a under the action of the second spring 4b, completing the locking between the connecting arm 31 and the mounting wall 11. Next, the tongue cover 2 is placed on the shoe, and finally the tongue cover 2 is fixed to the sole 1 with the strap structure to complete the wearing process.

[0037] When taking off shoes: Figures 5-7 As shown, first release the lock of the shoe tongue cover 2 on the strap, and the shoe tongue cover 2 is flipped forward to open; then move the locking button 6 obliquely upward to disengage the locking button 6 from the locking port 5a, and the second shaft 52 moves axially outward under the action of the first spring 4a, and the locking port 5a and the locking button 6 are misaligned, and the locking button 6 cannot be inserted into the locking port 5a, so that the connecting arm 31 can rotate around the axis of the second shaft 52 relative to the mounting wall 11; the leggings 3 are flipped backward to open, and the shoe inner cover can be completely and easily taken out of the shoe shell, and the independent shoe inner cover can be used as a daily shoe.
