Mode for Carrying Out the Invention

[0024] The present disclosure will be described in detail with reference to the accompanying drawings. For the sake of ease of explanation, the terms "upper", "lower", "top", "bottom" and other terms in the present disclosure mean the 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 by the vehicle floor. This improves the child safety seat's ability to prevent tipping and impact, thereby protecting the child's safety. However, it is inconvenient for the user to confirm whether or not the support leg device is in contact with the vehicle floor. Therefore, to solve the above problem, it is necessary to develop an indicator assembly for the child safety seat support leg device to inform the user whether the device is already properly assembled.

[0026] In the embodiment shown in Figure 1, the support leg device 10 is positioned at the front end of the base of the safety seat. When in use, the bottom 12 of the support leg device 10 may be supported by the vehicle floor. The support leg device 10 includes a first tube 20 and a second tube 30. The second tube 30 is slidably positioned inside the first tube 20, allowing the support leg device 10 to be extended or retracted. Therefore, 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 or not 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 located at the top 11 of the support leg device 10 and 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 located 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 located inside the support leg device 10.

[0029] As shown in Figure 1, the indicator housing 110 may be formed as a connector for connecting the support leg device 10 and the base of the safety seat. Therefore, the indicator housing 110 may be formed integrally with the support leg device 10 and the base of the safety seat, and sufficient strength may be provided between them, thereby ensuring that the support leg device 10 performs its support role relative to the safety seat. Of course, to facilitate manufacturing and transportation, the indicator housing 110, the support leg device 10, and the base of the safety seat may be manufactured separately and assembled by screwing, riveting, or welding.

[0030] The indicator window 111 is formed in the indicator housing 110 and penetrates the indicator housing 110. In the embodiments shown in Figures 1 and 2, the indicator window 111 is formed at the top of the indicator housing 110, so that the user can more conveniently observe the indicator window 111 from above. Alternatively, the indicator window 111 may be formed on the side of the indicator housing 110, so that the user can observe the indicator window 111 from the side.

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

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

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

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

[0036] The pressing member 200 is located inside the support leg device 10 and is movable up and down relative to the bottom 12 of the support leg device 10. The pressing 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 thermoplastic elastomer (TPE) material and serves to prevent slipping and avoid impact. Because 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 force from the floor surface, and the floor contact end 201 and the pressing 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 positioned within the hollow sleeve 310. The traction member 300 is a flexible, elongated member such as a traction wire, and is formed from a tensioning material such as metal, textile, rubber, or plastic. The sleeve 310 is a hollow tube that wraps around the traction member 300 and guides its movement, 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 made from a material having a predetermined elasticity and predetermined rigidity, such as metal, textile, rubber, or plastic. The sleeve 310 is elastic and is designed to bend and deform accordingly when the support leg device 10 retracts, so that the sleeve 310 does not hinder the extension and retraction of the support leg device 10. The sleeve 310 has rigidity that allows it to guide the movement of the traction member 300 and ensures that the overall length of the sleeve 310 does not change due to the movement of the traction 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. The 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, so that the indicator member 100 is pulled to rotate to a second position in a second direction opposite to the first direction. The second end 302 of the traction member 300 protrudes from the lower end 312 of the sleeve 310 and is positioned so that the upward movement of the push member 200 can drive the upward movement of the second end 302 of the traction member 300.

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

[0040] On the other hand, 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. Thus, the above can be implemented in various ways, which will be described in detail below with examples.

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

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

[0043] Furthermore, 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 and the distance between the top 11 and bottom 12 of the support leg device 10 is changed, only the distance between the ends of the sleeve 310 changes. However, unless the support leg device 10 is in contact with the floor surface, this change cannot pull the traction member 300 inside the sleeve 310, and the indicator member 100 cannot rotate to the second position. Also, when the support leg device 10 is fully extended, the distance between the ends of the sleeve 310 is at its maximum, and as a result, 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 aesthetic reasons and ease of use, as shown in Figures 5, 7, and 11. vinegar Thus, the entire sleeve 310 is positioned inside the support leg device 10, although the sleeve 310 may be provided partially or entirely outside the support leg device 10.

[0045] To enable those skilled in the art to better understand this disclosure, several preferred examples of this disclosure are described in detail.

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

[0047] In this embodiment, the lower end 312 of the sleeve 310 is positioned close to the upper end 31 of the second pipe 30, a retaining member 400 is provided on the upper end 31 of the second pipe 30, and the lower end 312 of the sleeve 310 is fixed to the retaining member 400. Thus, since the retaining member 400 provided on the second pipe 30 is immovable relative to the lower end of the second pipe 30, the lower end 312 of the sleeve 310 fixed to the retaining member 400 is immovable relative to the lower end of the second pipe 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 pipe 30, or it may be provided on other components of the upper end 31.

[0048] On the other hand, when the lower end 312 of the sleeve 310 is positioned close to the upper end 31 of the second pipe 30, the push 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 push member exceeds the height of the lower end 312 of the sleeve 310, and the second part 302 of the traction member 300 is fixed to the upper part 202 of the push member 200. When the lower end 312 of the sleeve 310 is fixed to the retaining member 400, the upper part 202 of the push member 200 penetrates the retaining member 400, as shown in Figures 5 and 6. Since the pressing member 200 extends from the lower end of the second pipe 30 (i.e., the bottom 12 of the support leg device 10) to the upper end 31 of the second pipe 30, that is, since the pressing member 200 extends along almost the entire length of the second pipe 30, although the pressing member 200 is shown as a sheet-like elongated member in Figures 5 and 6, it may also be a rod-like member.

[0049] Please note that the term "height" as used 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. Therefore, when the support leg device 10 is lifted off the floor, the action of the second elastic member 210 causes the pushing member 200 to move downward relative to the bottom 12 of the support leg device 10, and its floor contact end 201 extends again from the bottom 12 of the support leg device 10. At the same time, the upper part 202 and the second end 302 of the traction member 300 also move downward, resulting in the traction member at the second end 302 moving downward and retracting into the sleeve 310. Therefore, the traction member at the first end 301 moves upward and extends out of the sleeve 310, and as a result, the action of the first elastic member 120 causes the indicator member 100 to rotate to a first position along the first direction.

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

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

[0053] In this embodiment, the lower end 312 of the sleeve 310 is positioned close 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. Thus, since 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 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 also 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 pipe 30.

[0054] On the other hand, when the lower end 312 of the sleeve 310 is positioned close to the bottom 12 of the support leg device 10, the push member 200 extends upward along the longitudinal direction of the support leg device 10 from the floor contact end 201 until the height of the upper part 202 of the push member exceeds the height of the lower end 312 of the sleeve 310, and the second part 302 of the traction member 300 is fixed to the upper part 202 of the push member 200. Figure 10 is a perspective view showing a solution for the push member 200. Of course, the push member 200 may be implemented by other solutions as long as they can satisfy 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 upward-extending push member 200. As shown in Figures 7 to 9, the sleeve lower end fixing member 500 is positioned below the upper part 202 of the push member 200.

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

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

[0057] In this embodiment, the lower end 312 of the sleeve 310 is positioned close to the bottom 12 of the support leg device. For example, the lower end 312 of the sleeve 310 may be directly fixed to the inner wall of the lower end of the second pipe 30 or to other components provided on the bottom 12 of the support leg device 10, so that the lower end 312 of the sleeve 310 is immovable relative to the bottom of the support leg device 10.

[0058] On the other hand, when the lower end 312 of the sleeve 310 is positioned close to the bottom 12 of the support leg device 10, the push member 200 is provided with a drive member 600 that extends upward along the longitudinal direction of the support leg device 10 in order to enable the upward movement of the push member 200 to drive the upward movement of the second end 302 of the traction member 300. The height of the upper part 601 of the drive member exceeds the height of the lower end 312 of the sleeve 310, and the second end 302 of the traction member 300 is fixed to the upper part 601 of the drive member 600. In this embodiment, since the lower end 312 of the sleeve 310 is not high, the height of the upward-extending drive member 600 does not need to be high.

[0059] The drive member 600 is connected to a third elastic member 610 which moves the drive member 600 downward relative to the bottom 12 of the support leg device 10. Therefore, when the support leg device 10 is lifted off the floor, the drive member 600 moves downward relative to the bottom 12 of the support leg device 10 due to the action of the third elastic member 610, and as a result the push member 200 also moves downward, and its floor contact end 201 extends again from the bottom 12 of the support leg device 10. At the same time, the upper part 601 of the drive member 600 and the second end 302 of the traction member 300 also move downward, and as a result the traction member at the second end 302 moves downward and retracts into the sleeve 310. Therefore, the traction member at the first end 301 can move upward and extend out of the sleeve 310, and as a result the indicator member 100 rotates to a first position along a first direction due to the action of the first elastic member 120.

[0060] The third elastic member 610 may be formed of an elastic material and may include a spring, an elastic piece, or any elastic element capable of providing a driving force. Figures 11 to 14 show the third elastic member 610 as a compression spring provided on the drive member 600, but the disclosure is not limited thereto. The third elastic member 610 may be provided on the drive member 600 or at any suitable position on the push member 200, insofar as it is biased to eventually move downward.

[0061] Furthermore, in the second and third embodiments of this disclosure, the lower end 312 of the sleeve 310 is positioned 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 extends to its maximum and retracts to its minimum, and the distance between the two ends of the sleeve 310 changes significantly. 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 to be longer so that the sleeve 310 winds up inside the support leg device 10 when the support leg device 10 retracts. To avoid the effect on the extension and retraction of the support leg device 10 caused by the winding of the sleeve 310, the sleeve 310 is adjusted in two ways in this disclosure.

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

[0063] The second method is shown in Figures 11 to 14, and the sleeve 310 includes a first section 310A adjacent to the upper end 311 and a second section 310B adjacent to the lower end 312. The first section 310A is a leather sleeve, and the second section 310B is a spring sleeve, and the first section 310A and the second section 310B are connected at node 310C. In this way, due to the high rigidity of the leather sleeve, the first section 310A is essentially not wound. Conversely, due to the high elasticity of the spring sleeve, winding may occur in the second section 310B, thereby effectively limiting the length of the sleeve that can be wound.

[0064] The second section 310B of the sleeve 310 may be wound to form a second loop 314. The second loop 314 is wound around a post member 700 in the support leg device 10. The post member 700 may be formed on the inner wall of the support leg device 10, as shown in Figures 11 and 12, or it may be formed on other components within the support leg device 10.
