[0024] The present disclosure will now be described in detail with reference to the accompanying drawings, in which: For ease of description, the terms "upper", "lower", "top", "bottom" and other terms in this disclosure refer to directions within the accompanying drawings.

[0025] A support leg device for a child safety seat is provided, which is attached to the base of the child safety seat and supported on the vehicle floor surface, thereby improving the anti-tip and anti-shock ability of the child safety seat and protecting the safety of the child. However, it is inconvenient for a user to check whether the support leg device is in contact with the vehicle floor surface. Therefore, in order to solve the above problem, it is necessary to develop an indicator assembly for the support leg device for a safety seat to inform the user whether the device has been assembled properly.

[0026] In the embodiment shown in FIG. 1, the support leg device 10 is disposed at the front end of the base of the safety seat. In use, the bottom 12 of the support leg device 10 may be supported on the vehicle floor. The support leg device 10 includes a first tube 20 and a second tube 30. The second tube 30 is slidably disposed inside the first tube 20, thereby allowing the support leg device 10 to be extended or retracted. Thus, when the safety seat is placed on the car seat, the bottom 12 of the support leg device can reach the vehicle floor by adjusting the length of the support leg device 10.

[0027] The structure for indicating whether the support leg device 10 is in contact with the floor surface will be described in detail below. The indicator assembly according to the present invention is attached to the support leg device 10.

[0028] The indicator assembly is disposed on the top 11 of the support leg device 10, more specifically, connected to the upper end of the first tube 20 and includes an indicator housing 110 having an indicator window 111, an indicator member 100 rotatably housed within the indicator housing 110, a first elastic member 120 disposed within the indicator housing 110 and in contact with the indicator member 100 to rotate the indicator member 100 in a first direction, and a pushing member 200 and a pulling member 300 disposed inside the support leg device 10.

[0029] 1, the indicator housing 110 may be formed as a connection for connecting the support leg device 10 and the base of the safety seat. Therefore, the indicator housing 110 may be integrally formed with the support leg device 10 and the base of the safety seat and have sufficient strength therebetween, thereby ensuring that the support leg device 10 plays a supporting role for the safety seat. Of course, for ease of manufacturing and transportation, the indicator housing 110, the support leg device 10 and the base of the safety seat may be manufactured separately and then assembled by screwing, riveting or welding.

[0030] The indicator window 111 is formed in the indicator housing 110 and passes through the indicator housing 110. In the embodiment shown in Figures 1 and 2, the indicator window 111 is formed at the top of the indicator housing 110, so that a user can more conveniently observe the indicator window 111 from above. It should be noted that the indicator window 111 may also be formed at the side of the indicator housing 110, so that a user can observe the indicator window 111 from the side.

[0031] The indicator member 100 is rotatably accommodated in the indicator housing 110. As shown in FIG. 4, the indicator member 100 includes a first region 101 and a second region 102 on its outer surface. The first region and the second region can be alternately exposed from the indicator window 111 by rotating the indicator member 100. The first region 101 and the second region 102 may have different colors, such as red and green, or may have different patterns, such as letters and figures, thereby indicating different states of the indicator assembly. For example, when the support leg device 10 is not in contact with the floor surface, the first region 101 of the indicator member 100 is exposed from the indicator window 111, and when the support leg device 10 is in contact with the floor surface, the second region 102 of the indicator member 100 is exposed from the indicator window 111. This allows the user to clearly know whether the support leg device 10 is in contact with the floor surface or not.

[0032] To facilitate the rotation of the indicator member 100, as shown in Figure 4, a pivot axis 103 may be formed on both sides of the indicator member 100, and as shown in Figures 3 and 5, the pivot axis 103 may be rotatably supported on an indicator housing 110, or on the top 11 of the support leg arrangement 10 (i.e., the first tube 20), or on a frame 40 disposed on the top 11 of the support leg arrangement 10 (i.e., the first tube 20), such that the indicator member 100 rotates within the indicator housing 110 about the pivot axis 103. In other embodiments, the indicator member 100 may rotate by other means, such as a sliding rail.

[0033] When the support leg device 10 is not in contact with the floor surface, a first elastic member 120 is also disposed in the indicator housing 110 to ensure that the first region 101 is exposed from the indicator window 111, and rotates the indicator member 100 to a first position along a first direction, and when the indicator member 100 is in the first position, the first region 101 is exposed from the indicator window 111. The first elastic member 120 is made of an elastic material and may be a spring, an elastic piece, or any elastic element that can provide a driving force. In addition, the first elastic member 120 may be integrally formed with the indicator member 100, or the first elastic member and the indicator member may be assembled after being formed separately. The first elastic member 120 may have any shape.

[0034] When the support leg device 10 is in contact with the floor surface, the indicator member 100 is driven to rotate to a second position along a second direction opposite to the first direction mainly by the pushing member 200 and the pulling member 300. When the indicator member 100 is in the second position, the second region 102 is exposed through the indicator window 111.

[0035] Next, the pushing member 200 and the pulling member 300 will be briefly described.

[0036] The pushing member 200 is disposed inside the support leg device 10 and can move up and down relative to the bottom 12 of the support leg device 10. The pushing member 200 includes a floor contact end 201 that protrudes from the bottom 12 of the support leg device 10 and contacts the floor surface. The bottom of the floor contact end 201 is made of a thermoplastic elastomer (TPE) material, which serves to prevent slipping and avoid impact. Since the floor contact end 201 extends from the bottom 12 of the support leg device 10, when the support leg device 10 contacts the floor surface, the floor contact end 202 first contacts the floor surface and receives an upward acting force from the floor surface, and the floor contact end 201 and the pushing member 200 move upward relative to the bottom 12 of the support leg device 10 until the floor contact end 201 is completely retracted into the bottom 12 of the support leg device 10.

[0037] The traction member 300 is movably disposed within a hollow sleeve 310. The traction member 300 is a flexible elongated member, such as a traction wire, and is formed of a tensile material, such as metal, fabric, rubber, or plastic. The sleeve 310 is a hollow tube that wraps around the traction member 300 and guides the movement of the traction member 300, so that when one end of the traction member 300 is pulled out of the sleeve 310, the other end of the traction member 300 is pulled into the sleeve 310. The sleeve 310 may be manufactured from a material having a predetermined elasticity and a predetermined rigidity, such as metal, fabric, rubber, or plastic. The sleeve 310 has elasticity to ensure that when the support leg device 10 is retracted, the sleeve 310 can bend and deform accordingly, so that the sleeve 310 does not hinder the extension and contraction of the support leg device 10. The sleeve 310 has a rigidity that allows the sleeve 310 to guide the movement of the towing member 300 and ensures that the overall length of the sleeve 310 does not change with the movement of the towing member 300 .

[0038] The sleeve 310 has an upper end 311 configured to be immovable relative to the top 11 of the support leg device 10 and a lower end 312 configured to be immovable relative to the bottom 12 of the support leg device 10. A first end 301 of the traction member 300 extends from the upper end 311 of the sleeve 310 and is fixed to the indicator member 100 such that the indicator member 100 is pulled to rotate in a second direction opposite to the first direction to a second position. A second end 302 of the traction member 300 protrudes from the lower end 312 of the sleeve 310 and is positioned such that upward movement of the push member 200 can drive upward movement of the second end 302 of the traction member 300.

[0039] The upper end 311 of the sleeve 310 is configured to be immovable relative to the top 11 of the support leg device 10 in various ways. For example, in another embodiment, as shown in FIG. 5, the sleeve upper end fixing member 130 may be fixed to the top 11 of the support leg device 10, and the upper end 311 of the sleeve 310 may be fixed to the sleeve upper end fixing member 130. The sleeve upper end fixing member 130 may be fixed to the top 11 of the support leg device 10 via a frame 40. The sleeve upper end fixing member 130 and the frame 40 may be fixed using various conventional connection methods such as screws and rivets. Of course, the upper end 311 of the sleeve 310 may be directly fixed to the top 11 of the support leg device 10 or to another member disposed on the top 11.

[0040] Meanwhile, the lower end 312 of the sleeve 310 is configured to be immovable relative to the bottom 12 of the support leg device 10, and the second end 302 of the traction member 300 is configured such that the upward movement of the push member 200 can drive the upward movement of the second end 302 of the traction member 300, so that the above can be implemented in various ways, which will be described in detail below by giving examples.

[0041] The following describes how the push member 200 and the pull member 300 rotate the indicator member 100 along the second direction to the second position.

[0042] When the support leg device 10 is in contact with the floor surface, the floor contact end 201 of the pushing member 200 first contacts the floor surface, causing the pushing member 200 to move upward relative to the bottom 12 of the support leg device 10, thereby driving the second end 302 of the traction member 300 to move upward, and the first end 301 of the traction member 300 moves downward relative to the top 11 of the support leg device 10 to pull the indicator member 100, causing the indicator member 100 to rotate along the second direction against the force of the first elastic member 120, thereby exposing the second region 102 of the indicator member 100 from the indicator window 111.

[0043] In addition, since both ends of the sleeve 310 are fixed to the top 11 and bottom 12 of the support leg device 10, respectively, when the support leg device 10 is retracted to change the distance between the top 11 and bottom 12 of the support leg device 10, only the distance between both ends of the sleeve 310 changes. However, unless the support leg device 10 contacts the floor surface, this change cannot pull the traction member 300 in the sleeve 310, and the indicator member 100 cannot rotate to the second position. In addition, when the support leg device 10 is maximally extended, the distance between both ends of the sleeve 310 is maximized, so that the length of the sleeve 310 may be set longer than the required sleeve length, thereby ensuring that the extension of the support leg device 10 is not limited by the length of the sleeve 310.

[0044] Furthermore, for aesthetics and ease of use, the entire sleeve 310 is positioned inside the support leg device 10 as shown in Figures 5, 7 and 11, although the sleeve 310 may be partially or entirely located outside the support leg device 10.

[0045] Some preferred examples of the present disclosure will now be described in detail so that those skilled in the art can understand the present disclosure more clearly.

[0046] 5 to 6 show a first embodiment of the present disclosure.

[0047] In this embodiment, the lower end 312 of the sleeve 310 is disposed close to the upper end 31 of the second tube 30, a holding member 400 is provided at the upper end 31 of the second tube 30, and the lower end 312 of the sleeve 310 is fixed to the holding member 400. In this manner, the holding member 400 provided at the second tube 30 is immovable relative to the lower end of the second tube 30, and therefore the lower end 312 of the sleeve 310 fixed to the holding member 400 is immovable relative to the lower end of the second tube 30 (i.e., the bottom 12 of the support leg device 10). Of course, the lower end 312 of the sleeve 310 may be directly fixed to the inner wall of the upper end 31 of the second tube 30, or may be provided to another component at the upper end 31.

[0048] On the other hand, when the lower end 312 of the sleeve 310 is disposed adjacent to the upper end 31 of the second tube 30, the pushing member 200 extends upward from the floor contact end 201 along the longitudinal direction of the support leg device 10 until the height of the upper portion 202 of the pushing member exceeds the height of the lower end 312 of the sleeve 310 and the second end portion 302 of the pulling member 300 is fixed to the upper portion 202 of the pushing member 200, so that the upward movement of the pushing member 200 can drive the upward movement of the second end portion 302 of the pulling member 300. When the lower end 312 of the sleeve 310 is fixed to the holding member 400, the upper portion 202 of the pushing member 200 penetrates the holding member 400, as shown in FIG. 5 and FIG. 6. Because the pushing member 200 extends from the lower end of the second tube 30 (i.e., the bottom 12 of the support leg device 10) to the upper end 31 of the second tube 30, i.e., because the pushing member 200 extends along almost the entire length of the second tube 30, in Figures 5 and 6 the pushing member 200 is shown as a sheet-like elongated member, but it may also be a rod member.

[0049] It should be noted that the "height" referred to in this disclosure refers to the height from the bottom 12 of the support leg device 10.

[0050] The pushing member 200 may be connected to a second elastic member 210, which moves the pushing member 200 downward relative to the bottom 12 of the support leg device 10. Thus, when the support leg device 10 leaves the floor surface, the pushing member 200 moves downward relative to the bottom 12 of the support leg device 10 under the action of the second elastic member 210, and its floor contact end 201 extends from the bottom 12 of the support leg device 10 once again, and at the same time, the upper portion 202 and the second end 302 of the traction member 300 also move downward, so that the traction member at the second end 302 moves downward and retracts into the sleeve 310. Thus, the traction member at the first end 301 moves upward and extends from the sleeve 310, so that the indicator member 100 rotates along the first direction to a first position under the action of the first elastic member 120.

[0051] The second elastic member 210 is made of an elastic material and may include a spring, an elastic piece, or any elastic element capable of providing a driving force. Although Fig. 5 and Fig. 6 show that the second elastic member 210 is a tension spring provided on the pushing member 200, the present disclosure is not limited thereto, and the second elastic member 210 may be provided at any suitable position on the pushing member 200 as long as the pushing member 200 is biased to move downward.

[0052] 7 to 10 show a second embodiment of the present disclosure.

[0053] In this embodiment, the lower end 312 of the sleeve 310 is disposed adjacent to the bottom 12 of the support leg device 10, the bottom 12 of the support leg device 10 includes a sleeve lower end fixing member 500, and the lower end 312 of the sleeve 310 is fixed to the sleeve lower end fixing member 500. In this manner, the sleeve lower end fixing member 500 is immovable relative to the bottom 12 of the support leg device 10, and therefore the lower end 312 of the sleeve 310 fixed to the sleeve lower end fixing member 500 is immovable relative to the bottom 12 of the support leg device 10. The lower end 312 of the sleeve 310 may be directly fixed to the bottom 12 of the support leg device 10 or to the inner wall of the lower end of the second tube 30.

[0054] On the other hand, when the lower end 312 of the sleeve 310 is disposed close to the bottom 12 of the support leg device 10, in order to realize that the upward movement of the pushing member 200 drives the upward movement of the second end 302 of the towing member 300, the pushing member 200 extends upward from the floor contact end 201 along the longitudinal direction of the support leg device 10 until the height of the upper part 202 of the pushing member exceeds the height of the lower end 312 of the sleeve 310 and the second end 302 of the towing member 300 is fixed to the upper part 202 of the pushing member 200. FIG. 10 is a perspective view showing a solution of the pushing member 200. Of course, the pushing member 200 may be realized by other solutions as long as it can meet the above requirements. In this embodiment, since the lower end 312 of the sleeve 310 is not high, there is no need to increase the height of the pushing member 200 extending upward. As shown in FIGS. 7 to 9, the sleeve lower end fixing member 500 is disposed below the upper part 202 of the pushing member 200.

[0055] Although not shown, the pushing member 200 in this embodiment may be connected to a second elastic member 210, which moves the pushing member 200 downward relative to the bottom 12 of the support leg device 10.

[0056] 11 to 14 show a third embodiment of the present disclosure.

[0057] In this embodiment, the lower end 312 of the sleeve 310 is disposed adjacent to the bottom 12 of the support leg apparatus. For example, the lower end 312 of the sleeve 310 may be directly fixed to an inner wall of the lower end of the second tube 30 or other component provided on the bottom 12 of the support leg apparatus 10, such that the lower end 312 of the sleeve 310 is immovable relative to the bottom of the support leg apparatus 10.

[0058] On the other hand, when the lower end 312 of the sleeve 310 is disposed close to the bottom 12 of the support leg device 10, in order to realize that the upward movement of the pushing member 200 drives the upward movement of the second end 302 of the pulling member 300, the pushing member 200 is provided with a driving member 600 extending upward along the longitudinal direction of the support leg device 10, and the height of the upper part 601 of the driving member exceeds the height of the lower end 312 of the sleeve 310, and the second end 302 of the pulling member 300 is fixed to the upper part 601 of the driving member 600. In this embodiment, since the lower end 312 of the sleeve 310 is not high, the height of the upwardly extending driving member 600 does not need to be high.

[0059] The driving member 600 is connected to a third elastic member 610 which causes the driving member 600 to move downward relative to the bottom 12 of the support leg device 10. Thus, when the support leg device 10 leaves the floor surface, the driving member 600 moves downward relative to the bottom 12 of the support leg device 10 under the action of the third elastic member 610, so that the pushing member 200 also moves downward and its floor contact end 201 extends from the bottom 12 of the support leg device 10 once again. At the same time, the upper portion 601 of the driving member 600 and the second end 302 of the traction member 300 also move downward, so that the traction member at the second end 302 moves downward and retracts into the sleeve 310. Thus, the traction member at the first end 301 can move upward and extend from the sleeve 310, so that the indicator member 100 rotates to a first position along a first direction under the action of the first elastic member 120.

[0060] The third elastic member 610 is made of an elastic material and may include a spring, an elastic piece, or any elastic element capable of providing a driving force. Although Figs. 11 to 14 show that the third elastic member 610 is a compression spring provided on the driving member 600, the present disclosure is not limited thereto. The third elastic member 610 may be provided at any suitable position on the driving member 600 or the pushing member 200, as long as the third elastic member 610 is biased so as to eventually move the pushing member 200 downward.

[0061] Furthermore, in the second and third embodiments of the present disclosure, the lower end 312 of the sleeve 310 is disposed close to the bottom 12 of the support leg device 10, so that when the upper end 311 of the sleeve 310 is fixed to the top 11 of the support leg device 10 or a component at that position, the support leg device 10 will be maximally extended and minimally retracted, and the distance between the two ends of the sleeve 310 will be greatly changed. In order to ensure that the extension of the support leg device 10 is not limited by the length of the sleeve 310, the length of the sleeve 310 is set longer so that the sleeve 310 will be wound inside the support leg device 10 when the support leg device 10 retracts. In order to avoid the influence on the extension and contraction of the support leg device 10 caused by the sleeve 310 being wound, the sleeve 310 is adjusted in two ways in the present disclosure.

[0062] In the first method, shown in Figures 7 to 9, a retaining member 400 is provided on the upper end 31 of the second tube 30, and a sleeve 310 is wound into a first loop 313 in the space below the retaining member 400 within the support leg device 10. A lower portion of the retaining member 400 extends from a sleeve retaining portion 401, and the first loop 313 is suspended from the sleeve retaining portion 401.

[0063] 11-14, in which a sleeve 310 includes a first section 310A proximate the upper end 311 and a second section 310B proximate the lower end 312. The first section 310A is a leather sleeve and the second section 310B is a spring sleeve, with the first section 310A and the second section 310B connected at node 310C. In this manner, due to the greater stiffness of the leather sleeve, the first section 310A is essentially unrolled. Conversely, due to the greater elasticity of the spring sleeve, rolling may occur at the second section 310B, thereby effectively limiting the length of the sleeve that can be rolled.

[0064] The second section 310B of the sleeve 310 may be wound into a second loop 314. The second loop 314 is wound around a post member 700 within the support leg apparatus 10. The post member 700 may be formed on an inner wall of the support leg apparatus 10, as shown in Figures 11 and 12, or may be formed on another component within the support leg apparatus 10.
