Description

[Technical Field]

[0001] The present disclosure relates to a support mechanism, a support leg having a support mechanism, and a carrier having a support leg. [Background technology]

[0002] Generally, child car seats are provided with support legs at the front of the seat. One end of the support legs is fixed to the base of the child car seat, and the other end of the support legs is supported on the floor of the vehicle, resulting in a more stable installation of the child car seat. However, if the support legs do not stably contact the floor, there is a risk that the child car seat will tip over. For this reason, it is necessary to ensure that the support legs are in contact with the ground when using the seat.

[0003] Currently available support legs are extendable and foldable relative to the base, but the extendable mechanism of the support legs does not provide any indication of whether the support legs are securely positioned, creating a potential safety hazard if the support legs are misused when they are not fully extended and in firm contact with the floor surface. Summary of the Invention

[0004] The present disclosure provides a novel support leg grounding indication mechanism, which is a simple overall mechanism that can provide grounding indications for the support legs and / or indications that the support legs are fully extended from the base, thereby avoiding various potential risks caused by improper user operation.

[0005] According to the present disclosure, there is provided an indicating mechanism for indicating whether a component is in contact with a surface, the component having an indicating end and a contact end vertically opposed to each other, the indicating mechanism being attached to the component, the indicating mechanism comprising: an indicator disposed at the indicating end and movable between a first position and a second position to indicate whether the component is in contact with the surface, a driver movably disposed at the contact end, a cable sleeve including a first end fixed to the indicating end and a second end fixed to the driver, and a cable movably disposed within the cable sleeve and including a first end and a second end extending from opposite ends of the cable sleeve, the first end of the cable being fixed to the indicator and capable of moving the indicator, and the second end of the cable being fixed to the contact end, wherein when the component contacts the surface, the driver drives the second end of the cable sleeve away from the contact end, causing the cable to move relative to the cable sleeve toward the contact end, thereby moving the indicator.

[0008] Although the present disclosure is illustrated and described herein with reference to particular embodiments, the present disclosure should not be limited to the details shown. Indeed, many changes may be made to these details, within the scope and range of equivalents of the claims, without departing from the present disclosure.

[0009] The descriptions of directions such as "front", "rear", "upper", and "lower" referred to in this specification are for ease of understanding only, and the present disclosure is not limited to these directions and can be adjusted according to actual circumstances.

[0010] Please refer to Figures 1 to 3. In the embodiment of the present disclosure, the carrier 200 is a child car seat, but is not limited to this. The present disclosure can be applied to any carrier 200 that requires support legs 100.

[0011] As shown in the figure, the carrier 200 includes a base 210 and a seat 220. The base 210 is a portion for fixing the carrier 200 to a vehicle seat, and the seat 220 is a portion for carrying a passenger (i.e., a child). The support legs 100 are attached below the base 210, more specifically, to the front side below the base 210, and are configured to support the base 210 against the floor surface of the vehicle and prevent the child car seat from tipping forward in the event of a vehicle collision.

[0012] In one embodiment, the support leg 100 is coupled to the base 210 by an extendable bracket 170 (see FIG. 5 ) such that the support leg 100 is movable longitudinally (i.e., forward and backward) relative to the base 210, extending out from the base 210 and retracting to a position below the base 210. It should be understood that the support leg 100 can be coupled directly to the base 210.

[0013] The cover 160 covers the upper part of the support leg 100, and a cover indicator 165 is provided on the upper surface of the cover 160 so that the user can observe whether the support leg 100 is fully extended from the base 210. The cover indicator 165 is provided at the rear end of the cover 160, and when the cover 160 is fully extended, the cover indicator 165 moves away from the base 210. The cover indicator 165 has an easily observable color, such as green or other color that has a strong contrast with the color of the support leg 100, to attract the user's attention.

[0014] 1, the support leg 100 is fully extended from the base 210, and the cover support portion 165 is visible. In the state shown in FIG. 2, the support leg 100 is not fully extended from the base 210, and the cover support portion 165 is not visible.

[0015] The front end of the cover 160 may be provided with a hollow portion or a transparent window 166 so that the user can observe the indicator 110 provided on the support leg 100 (see FIG. 4). The indicator 110 is configured to indicate whether the bottom end of the support leg 100 is grounded or not, and its structure and principle will be described in detail later. Note that "grounded" means that a component such as the support leg 100 is in contact with the floor surface and is stably supported on the floor surface.

[0016] In one embodiment, the length of the support leg 100 can be adjusted. Specifically, the support leg 100 includes an upper tube 101 having a supporting end and a lower tube 102 having a contact end. The upper tube 101 of the support leg 100 is fitted onto the lower tube 102 of the support leg 100 and has a corresponding positioning device (e.g., an engaging element or pin) so that the overall length of the support leg 100 can be adjusted.

[0017] The upper end (referred to as the support end) of the support leg 100 is coupled to the bracket 170 (or, in embodiments without the bracket 170, directly coupled to the base 210). The lower end (referred to as the contact end) of the support leg 100 is used to contact the floor surface. In one embodiment, a fixing seat 140 may be provided at the contact end to facilitate assembly of the support mechanism of the present disclosure. In other embodiments, the fixing seat 140 may be integrated into the support leg 100 and formed as a unitary part therewith.

[0018] In one embodiment, the support legs 100 can be rotated together about the supporting end to a position below the base 210, as shown in Figure 3. In this manner, the support legs 100 can be folded completely into the base 210, facilitating transportation of the carrier 200.

[0019] 4 and 5, as shown, the bracket 170 for connecting the support leg 100 to the base 210 includes a slide mechanism 171 and a support leg rotation shaft 175. Here, the slide mechanism 171 is a hinged connecting rod and / or a slide rail, and a spring is provided in the slide mechanism 171 so as to urge the support leg 100 toward a position below the base 210. The support leg rotation shaft 175 extending in the left-right direction (i.e., the lateral direction) is provided at the front end of the bracket 170, and the upper end of the support leg 100 is attached to the support leg rotation shaft 175 so as to allow the entire support leg 100 to rotate to a position below the base 210 (as shown in FIG. 3).

[0020] As shown in FIGS. 4 and 5, the indicator 110 of the indicating mechanism is exposed to the user through a hollow portion or transparent window 166 on the cover 160 so as to be observed by the user.

[0021] 6 to 8, the specific structure of the support mechanism according to the present disclosure and how the support mechanism is attached to the support leg 100 will be described below.

[0022] As shown, the indicating mechanism includes an indicator 110, a driver 130, a cable sleeve 155, and a cable 150. In some embodiments, the indicating mechanism further includes a mount 120, a first resilient member 182, a first screw 181 (as shown in FIGS. 9A and 9B ), a second resilient member 183, and a second screw 184.

[0023] The indicator 110 is disposed on the supporting end of the support leg 100 via a lateral movable shaft 114 and rotates around the movable shaft 114 between a first position and a second position. For example, the first position corresponds to a position where the support leg is not in contact with the floor surface, and the second position corresponds to a position where the support leg is in contact with the floor surface. In one embodiment, the first region 111 and the second region 112 are disposed along the circumferential direction of the cylindrical outer periphery of the indicator 110 (see FIGS. 9A and 9B ). When the support leg 100 is in the non-grounding position (i.e., when the support leg is not in contact with the floor surface), the first region 111 is exposed to the hollow portion or the transparent window 166, and when the support leg 100 is in the grounding position (i.e., when the support leg is in contact with the floor surface), the second region 112 is exposed to the hollow portion or the transparent window 166. For example, the first region 111 may be red and the second region 112 may be green, or different marks (e.g., dots, diagonal lines, or other patterns) may be applied to the second region 111 and the second region 112 as long as it is possible to indicate whether the support leg 100 is grounded or not. The shapes of the first region 111 and the second region 112 may correspond to the shape of the hollow portion or the transparent window 166. The embodiment of the present disclosure does not limit the shapes or colors of the first region and the second region to those described above.

[0024] The movable shaft 114 may be disposed directly on the supporting end of the support leg 100, or may be attached to the supporting end by a mount 120. For example, the movable shaft 114 is erected on two opposing upright walls of the mount 120, and the mount 120 is fixed to the supporting end. In the illustrated embodiment, the support leg 100 is a hollow tubular part, and the mount 120 is fixed to the inside of the supporting end, but the present disclosure is not limited thereto.

[0025] The first resilient member 182 is disposed between the indicator 110 and the first end 156 of the cable sleeve 155 and abuts the indicator 110 to bias the indicator 110 toward the first position.

[0026] A first side of indicator 110 is provided with first receiving portion 113 for receiving first end 151 of cable 150, and a second side of first elastic member 182 and indicator 110 abuts one end of first elastic member 182. The other end of first elastic member 182 is fixed to the indicating end. In one embodiment, the first side of indicator 110 is opposite the second side.

[0027] The drive unit 130 is at least partially disposed on the contact end of the support leg 100 and includes a contact portion 131 extending vertically outward from the contact end. The drive unit 130 moves relative to the contact end between an extended position where the contact portion 131 extends from the contact end and a retracted position where the contact portion 131 retracts into the contact end.

[0028] More specifically, the drive portion 130 includes a shoulder 135 and a hole 132. The shoulder 135 is located inside the contact end of the support leg 100 and extends substantially laterally, and the two contact portions 131 extend vertically from both lateral ends of the shoulder 135 to the outside of the contact end. The hole 132 is opened in the shoulder 135, and the shoulder 135 is slidably fitted onto a column 141 that extends inward from the bottom of the contact end.

[0029] In one embodiment, a second elastic member 183 is provided between the driver 130 and the contact end of the component, and the second elastic member 183 biases the driver 130 to the extended position. The second elastic member 183 may be a coil spring. The second elastic member 183 is fitted onto the column 141. One end of the second elastic member 183 abuts against the inside of the second screw 184, and the other end abuts against the shoulder 135 to bias the driver 130 to the extended position. However, it should be understood that the arrangement of the second elastic member 183 is not limited thereto, as long as the driver 130 is biased to the extended position.

[0030] The drive unit 130 further includes an attachment portion (i.e., second receiving portion 133) for the cable sleeve 155, which is in the form of a groove extending vertically inward from the center of the shoulder 135 and having a shape corresponding to the second end 157 of the cable sleeve for fixing the second end 157 of the cable sleeve. It should be understood that the shape of the attachment portion of the cable sleeve is not limited thereto and can be changed depending on the shape of the second end of the cable sleeve.

[0031] The fixed seat 140 is a substantially flat part extending in the horizontal and vertical directions. In an embodiment in which the fixed seat 140 is provided as a separate part, the lower end (contact end) of the support leg 100 may be an open end, and the fixed seat 140 is used to close the open end. The column 141 and the third receiving portion 142 are provided inside the fixed seat 140. A through hole is provided in the fixed seat 140 so that the contact portion 131 of the drive portion 130 extends outside the support leg 100. As described above, the fixed seat 140 can be integrated into the support leg 100 as a single part.

[0032] The cable sleeve 155 extends generally vertically between the supporting end and the contact end of the support leg 100. The cable sleeve 155 includes a first end 156 fixed to the supporting end and a second end 157 fixed to the drive unit 130. The cable sleeve 155 can be made of rubber or plastic that has some flexibility and can bend, but whose length remains substantially unchanged.

[0033] In one embodiment, both cable sleeve first end 156 and cable sleeve second end 157 are in the form of hammers with increasing diameters at either end, although it should be understood that cable sleeve first end 156 and cable sleeve second end 157 may be in other forms such as external threads, resilient engagement elements, or may be welded directly to support end and drive portion 130.

[0034] Cable 150 extends substantially vertically between the supporting end and the contact end of support leg 100 and is slidably sleeved within cable sleeve 155. Cable 150 includes first end 151 and second end 152 extending from opposite ends of cable sleeve 155, where first end 151 of the cable is fixed to indicator 110 and drives indicator 110 to rotate about movable shaft 114, and second end 152 of the cable is fixed to the contact end and further fixedly connected to base 140. Cable 150 is made of, for example, steel wire, nylon wire, carbon fiber, etc. and has a certain degree of flexibility and is bendable, but its length does not change much.

[0035] In one embodiment, both the first end 151 and the second end 152 of the cable are in the form of hammers with increasing diameters at either end, although it should be understood that the first end 151 and the second end 152 of the cable may be in other forms such as external threads, knots, or direct welds to the supporting and contact ends.

[0036] The operation of the indicating mechanism of the present disclosure will be described with reference to FIGS. 9A to 10B.

[0037] 9A and 10A, the indicator 110 is in its first position, and the driver 130 is in its extended position. The first region 111 of the indicator 110 faces upward (i.e., toward the hollow portion or transparent window 166 on the cover 160) to indicate that the support leg 100 is not in contact with the floor surface. Due to the biasing action of the first elastic member 182 and the second elastic member 183, in the absence of the influence of an external force, the indicator 110 and the driver 130 tend to be maintained in the positions shown in FIGS. 9A and 10A.

[0038] As shown in Figures 9B and 10B, the contact end contacts the floor surface. Because the contact portion 131 of the drive unit 130 is exposed to the outside of the support leg 100, it receives pressure from the floor surface and moves to the retracted position against the biasing force of the second elastic member 183. Because the second end of the cable sleeve is fixed to the drive unit 130, the drive unit 130 drives the second end 157 of the movable cable sleeve away from the contact end (i.e., moves upward). On the other hand, because the second end 152 of the cable is fixed to the contact end, the second end 152 of the cable does not move away from the contact end, i.e., does not move upward. This means that the second end 152 of the cable extends a constant length from the second end 157 of the cable sleeve. As described above, the lengths of the cable and the cable sleeve are substantially constant, i.e., the length of the portion of the cable 150 in the cable sleeve 155 is substantially constant. Thus, when cable second end 152 extends a certain length from cable sleeve second end 157, cable first end 151 retracts a corresponding length into cable sleeve first end 156. Because cable sleeve first end 156 is fixed to the indicating end of support leg 100, cable 150 slides relative to cable sleeve 155 toward the contact end, which in turn drives indicator 110 to rotate from its first position to its second position.

[0039] In other embodiments, the indicator 110 can be configured to move linearly instead of rotating. For example, the indicator 110 can be mounted on a slide rail at the indicator end and slide between a second position and a first position. The indicator 110 is biased to the first position without an external force. When the contact end contacts a surface, the cable 150 (specifically, the first end 151 of the cable) drives the indicator 110 to move to the second position against the biasing force. The slide rail can also be arranged horizontally, with the vertical movement of the cable 150 being converted to lateral movement by a pulley at the indicator end. The slide rail can also be arranged vertically, with a hollow or transparent window 166 formed in the vertical surface of the cover 160.

[0040] 11A-11B provide an explanation of the technical principle of the present application. When the cable sleeve 155 changes from the non-contact state shown in FIG. 11A to the contact state shown in FIG. 11B, the second end 157 of the cable sleeve is pushed upward, but because the first end 156 of the cable sleeve is fixed, the cable sleeve 155 is bent (the degree of bending is exaggerated in the figure). Because the cable 150 is sleeved within the cable sleeve 155 and must extend along the curved path of the cable sleeve 155, the extension path of the cable 150 from the supporting end to the contact end is actually longer. Because the second end 152 of the cable is fixed to the contact end, the first end 151 of the cable is retracted inward.

[0041] 11A shows the cable sleeve 155 and the cable 150 extending along a substantially straight line, it should be understood that the cable sleeve 155 and the cable 150 do not need to extend in a straight line when not in contact. In fact, the cable sleeve 155 and the cable 150 may be bent when not in contact, or may be bent more when in contact, while still achieving their function. The advantage of this feature is that the cable 150 and the cable sleeve 155 can be adapted to support legs 100 of various lengths. For example, the length of the cable 150 and the cable sleeve 155 can be designed to correspond to the maximum length of the support leg 100, and when the support leg 100 is adjusted to be shorter, the cable 150 and the cable sleeve 155 can be bent and connected between both ends of the support leg 100 and still achieve the function of contact support.

[0042] In one embodiment, the drive portion includes a contact portion that is at least partially exposed from the contact end and extends outside the contact end, and the drive portion is movable between an extended position and a retracted position relative to the contact end, wherein when the contact end contacts a surface, the drive portion moves accordingly from the extended position to the retracted position to drive the second end of the cable sleeve away from the contact end.

[0043] In one embodiment, the indicating end further includes a first elastic member disposed between the indicator and the first end of the cable sleeve and abutting the indicator (110) to bias the indicator to the first position.

[0044] In one embodiment, a first receiving portion for receiving a first end of the cable is provided on a first side of the indicator, and the first elastic member and the second side of the indicator abut one end of the first elastic member, and the other end of the first elastic member is fixed to the indicating end of the part, wherein the first side is opposite the second side.

[0045] In one embodiment, the indicating end is provided with a movable shaft or a slide rail, and the indicator is rotated between a first position and a second position via the movable shaft, or slid between the first position and the second position via the slide rail.

[0046] In one embodiment, the indicator includes a first region and a second region, and when the part is not in contact with the surface, the first region is exposed through a hollow portion or transparent window of the indicating mechanism, and when the part is in contact with the surface, the second region is exposed through the hollow portion or transparent window.

[0047] In one embodiment, a second resilient member is provided between the driver and the contact end of the component, the second resilient member biasing the driver to the extended position.

[0048] In one embodiment, the driver includes a shoulder extending generally laterally, and two contact portions extend outwardly from both lateral ends of the shoulder along a vertical direction as contact ends. A hole may be formed in the shoulder, and the hole may be fitted onto a column at the bottom of the contact ends. A second elastic member is fitted onto the column. The second elastic member is disposed between the column and the shoulder and biases the driver to the extended position.

[0049] In one embodiment, the drive portion further includes a second receiving portion extending vertically inward from the center of the shoulder, the second receiving portion being in the form of a groove and having a shape corresponding to the second end of the cable sleeve for securing the second end of the cable sleeve.

[0050] In one embodiment, the first end of the cable, the second end of the cable, the first end of the cable sleeve, and the second end of the cable sleeve are each in the form of a hammer having an enlarged diameter at its end.

[0051] In one embodiment, the cable is a steel wire.

[0052] In one embodiment, the first position of the indicator corresponds to a condition in which the component is not in contact with the surface, and the second position of the indicator corresponds to a condition in which the component is in contact with the surface.

[0053] A support leg for supporting a carrier according to the present disclosure on a surface is provided, the support leg including a support mechanism according to the present disclosure, wherein the component is the support leg, the surface is an interior floor surface of a vehicle, and the support leg is coupled at its supporting end to a base of the carrier.

[0054] In one embodiment, the support leg includes a cover that covers the supporting end of the support leg, and the top surface of the cover is provided with a hollow or transparent window for showing the indicator.

[0055] In one embodiment, the support legs are connected to the base of the carrier via brackets, and the brackets are connected to the base via vertically slidable slide mechanisms, allowing the support legs to slide into and out of positions below the bottom side of the base.

[0056] In one embodiment, a cover support portion is provided on the outer surface of the cover, the cover support portion being observable by the user when the support leg slides out of position under the base, and not observable by the user when the support leg slides into position under the base.

[0057] In one embodiment, the support leg is connected to the bracket via a rotation axis, and when the support leg slides into position below the base, the support leg can rotate below the base about the support leg rotation axis.

[0058] In one embodiment, the support leg includes an upper tube having a supporting end and a lower tube having a contact end, the upper tube being fitted over the lower tube and provided with a corresponding positioning device to allow the overall length of the support leg to be adjusted.

[0061] As described above, the present disclosure provides an indicator mechanism that intuitively indicates whether one end of a support leg is in contact with the ground at the other end of the support leg. Furthermore, the indicator mechanism of the present disclosure allows the length of the support leg to be changed, thereby achieving its touch indicator function. While the embodiment illustrates a support leg, it should be understood that the indicator mechanism of the present disclosure can be applied to various components with various shapes.

[0062] The present disclosure also provides a support leg that is provided with an indication mechanism and an extension indication mechanism, and that can indicate to a user the extension state and grounding state of the support leg.
