bracket

Abstract

This invention discloses a bracket comprising a fixed base and three support components. The fixed base includes three engaging portions, each containing multiple first engaging structures. Each support component includes a fixing component, a sliding member, and an engaging member. One end of the fixing component is pivotally connected to an engaging portion. The sliding member is sleeved around the periphery of the fixing component. The engaging member is connected to the fixing component. When the sliding member slides relative to the fixing component, it drives the engaging member to engage the second engaging structure of the engaging member with the first engaging structure, and the second limiting structure of the sliding member engages with the first limiting structure of the fixing component, thereby restricting the movement of the engaging member and the fixing component. The bracket of this invention allows users to adjust the angles of the fixing components and the fixed base of the bracket by simply operating the sliding member.

Description

Technical Field

[0001] This invention relates to a bracket, and more particularly to an adjustable-angle bracket. Background Technology

[0002] Existing common adjustable brackets have the problem of inconvenient operation. Summary of the Invention

[0003] This invention discloses a bracket, which is mainly used to improve the problem of inconvenient operation of known adjustable brackets.

[0004] One embodiment of the present invention discloses a bracket for placement on a support surface. The bracket includes: a fixed base including at least three engaging portions, each engaging portion including a plurality of first engaging structures; at least three support components, each support component including: a fixed component, one end of which is pivotally connected to one of the engaging portions; the fixed component including a first positioning structure; a sliding member sleeved around the fixed component, the sliding member including a second positioning structure; the second positioning structure being capable of engaging with the first positioning structure; and an engaging member connected to the fixed component, the engaging member being movable relative to the fixed component, the engaging member including a second engaging structure. The structure includes a second engaging structure that can engage with any adjacent first engaging structure; wherein, a slider can be operated to move relative to a fixed component between an unlocked position and a fixed position; when the slider moves from the unlocked position to the fixed position, the slider will drive the engaging component, causing the second engaging structure to engage with the adjacent first engaging structure, and the second positioning structure to engage with the first positioning structure; the range of motion of the engaging component is limited by the slider and the fixed component; when the slider is in the unlocked position, the engaging component can be operated to move relative to the fixed component so that the second engaging structure no longer engages with the adjacent first engaging structure.

[0005] Preferably, when the slider is in a fixed position, the engaging member is housed inside the slider, and the outer periphery of the engaging member abuts against the inner side of the slider.

[0006] Preferably, the fixing component further includes a third positioning structure. When the slider is in the unlocked position, the second positioning structure and the third positioning structure engage with each other, and the engaging component is not located inside the slider.

[0007] Preferably, each support component further includes an elastic element, one end of which is fixed to the fixing component, and the other end of which is fixed to the engaging component. When the sliding component is in the fixed position, the engaging component is driven by the sliding component, and the elastic element is compressed to generate an elastic restoring force. When the sliding component moves from the fixed position to the unlocked position, and the sliding component no longer drives the engaging component, the elastic restoring force of the elastic element will cause the engaging component to return to the position not driven by the sliding component, and the second engaging structure will change from a state of engaging with the first engaging structure to a state of not engaging with the first engaging structure.

[0008] Preferably, when the slider is in a fixed position, the engaging member is driven by the slider, and the elastic member is compressed to generate an elastic restoring force, and the elastic restoring force of the elastic member causes the outer periphery of the engaging member to abut against the inner side of the slider.

[0009] Preferably, each slider includes an opening and an elastic arm, the elastic arm being located in the opening, the second positioning structure being a protrusion formed on the elastic arm, and the first positioning structure being a recess formed on the fixing component; when the protrusion abuts against the periphery of the fixing component, the elastic arm elastically deforms.

[0010] Preferably, the engaging member includes a guide ramp; during the process of the slider moving from the unlocked position to the fixed position relative to the fixed component along a first direction, one end of the slider will drive the guide ramp, causing the engaging member to move relative to the fixed component in a second direction; the second direction is not parallel to the first direction.

[0011] Preferably, each fixing component includes a fixing member and a support foot. One end of the fixing member is pivotally connected to the fixing seat, and the other end of the fixing member has a first limiting structure. The end of the sliding member away from the fixing seat has a second limiting structure. The second limiting structure can abut against the first limiting structure, and the first limiting structure and the second limiting structure can jointly limit the range of motion of the sliding member relative to the fixing member. The fixing member is fixed to one end of the support foot, and the other end of the support foot is used to abut against the bearing surface.

[0012] Preferably, the periphery of the fixing member includes at least one first guide structure, and the inner side of the sliding member includes at least one second guide structure. The sliding member can cooperate with the first guide structure through the second guide structure to move relative to the fixing member in a first direction.

[0013] Preferably, the engaging member is movable between a non-engaged position and an engaged position. When the engaging member is in the non-engaged position, there is a gap between the second engaging structure and any adjacent first engaging structure, and the fixing component can be operated to rotate relative to the fixing seat. When the sliding member is in the fixed position and the engaging member is in the engaged position, the second engaging structure engages with the adjacent first engaging structure, and the fixing component cannot rotate relative to the fixing seat.

[0014] In summary, the bracket of the present invention, through the design of the fixing base, the fixing component, the locking component, the sliding component, etc. included in the support assembly, allows users to quickly and conveniently adjust the angle of the bracket.

[0024] In the following description, if a specific drawing is indicated or shown in a specific drawing, it is only to emphasize that most of the relevant content in the following description appears in that specific drawing, but does not limit the following description to referring only to that specific drawing.

[0025] Please refer to the following: Figures 1 to 6 , Figure 1 This is a schematic diagram of the bracket of the present invention. Figure 2 This is a partially enlarged schematic diagram of the bracket of the present invention. Figure 3 This is a partially enlarged schematic diagram showing the sliding components of the bracket of the present invention in the unlocked position. Figure 4 This is a partially exploded view of the stent of the present invention. Figure 5 This is an exploded view of the support assembly of the bracket of the present invention. Figure 6This is a partial cross-sectional view of the sliding member of the bracket of the present invention in the unlocked position. The bracket 100 of the present invention is used to place on a support surface (not shown in the figure). The support surface is, for example, the ground, a tabletop, etc., and is not limited thereto. The bracket 100 of the present invention can be used to support various cameras, camcorders, lamps, speakers, etc., and is not limited thereto.

[0026] The bracket 100 includes a fixed base 1 and three support components 2. The fixed base 1 includes a body 231 and three engaging portions 12. The body 231 may have a connecting structure 111 for engaging with various cameras, video cameras, lamps, speakers, pan-tilt heads, measuring devices, etc. The three engaging portions 12 are spaced apart from each other and connected to the body 231. The body 231 and the three engaging portions 12 may be integrally formed. Each engaging portion 12 includes a plurality of first engaging structures 121. The plurality of first engaging structures 121 included in each engaging portion 12 may, for example, be toothed. The number of support components 2 included in the bracket 100 is not limited to three; in different embodiments, the bracket 100 may also include four or more support components 2. The number of engaging portions 12 included in the fixed base 1 corresponds to the number of support components 2.

[0027] Each support assembly 2 includes a fixing component 21, a sliding component 22, a locking component 23, and a resilient component 24. The three fixing components 21 are pivotally connected to the three locking portions 12, and each fixing component 21 can be operated to rotate relative to the locking portion 12. It is worth mentioning that in different embodiments, each support assembly 2 may also not include the resilient component 24.

[0028] The fixing assembly 21 includes a fixing member 211, a support leg 212, and an auxiliary member 213. One end of the fixing member 211 is pivotally connected to the fixing base 1. In practical applications, the end of the fixing member 211 that is pivotally connected to the fixing base 1 may have two pivot arms 2111, which are spaced apart from each other. A receiving groove 2112 is formed between the two pivot arms 2111 on the fixing member 211. The receiving groove 2112 is used to receive a locking portion 12 of the fixing base 1. The locking portion 12 is pivotally connected to the two pivot arms 2111.

[0029] The other end of the fastener 211 may be recessed to form a mounting groove 2114. One end of the support leg 212 is fixedly disposed in the mounting groove 2114, and the other end of the support leg 212 is used to abut against the bearing surface. In practical applications, each support leg 212 and the fastener 211 may be mutually fixed only by fitting together, and there may also be adhesive between the support leg 212 and the fastener 211. In a special embodiment, each support leg 212 and the fastener 211 may also be detachably fixed together, and relevant personnel can replace different support legs 212 as needed. In different embodiments, the fastener 211 and the support leg 212 may also be integrally formed.

[0030] The sliding member 22 can be a cylindrical structure, and the fixed member 211 can also be roughly cylindrical in shape. The sliding member 22 is fitted around the fixed member 211, and the sliding member 22 can be operated to slide relative to the fixed member 211. The shape and size of the sliding member 22 and the fixed member 211 are not limited to those shown in the figure, as long as the sliding member 22 can be operated to slide relative to the fixed member 211. The shape and size of the sliding member 22 and the fixed member 211 can be varied according to requirements.

[0031] In practical applications, the end of the fixing member 211 opposite to the end pivotally connected to the fixing base 1 may have a first limiting structure 2115, while the end of the sliding member 22 away from the fixing base 1 has a second limiting structure 221. The sliding member 22 may be inserted from the end of the fixing member 211 without the first limiting structure 2115, and the second limiting structure 221 of the sliding member 22 is adjacent to the first limiting structure 2115. When the sliding member 22 is operated to slide relative to the fixing member 211 and the second limiting structure 221 abuts against the first limiting structure 2115, the range of motion of the sliding member 22 relative to the fixing member 211 will be restricted, and the sliding member 22 will no longer be able to move away from the fixing base 1. The design of the first limiting structure 2115 and the second limiting structure 221 is mainly used to limit the range of motion of the slider 22 and the fixed member 211. In different embodiments, the fixed member 211 and the slider 22 may not include the first limiting structure 2115 and the second limiting structure 221, and the range of motion of the slider 22 relative to the fixed member 211 can be limited by other means.

[0032] The periphery of the fastener 211 may have a first positioning structure 2116 and a third positioning structure 2117, the first positioning structure 2116 and the third positioning structure 2117 being spaced apart from each other, and the first positioning structure 2116 and the third positioning structure 2117 may be, for example, a recess formed by the inward recess of the periphery of the fastener 211.

[0033] The sliding member 22 has a second positioning structure 222, which can engage with the first positioning structure 2116 and the third positioning structure 2117 respectively. When the second positioning structure 222 engages with the first positioning structure 2116 or the third positioning structure 2117, the range of motion of the sliding member 22 relative to the fixed member 211 will be restricted.

[0034] In practical applications, the slider 22 may have an opening 223 and an elastic arm 224. The elastic arm 224 is located in the opening 223. The second positioning structure 222 may be a protrusion formed in the elastic arm 224. When the protrusion abuts against the periphery of the fixing member 211, the elastic arm 224 elastically deforms. Thus, when the slider 22 is operated to slide relative to the fixing member 211, the protrusion will continuously abut against the periphery of the fixing member 211 until the protrusion enters one of the recesses.

[0035] In one preferred embodiment, the periphery of the fixing member 211 may further include two first guide structures 2118, and the inner side of the sliding member 22 includes two second guide structures 225. The sliding member 22 can cooperate with the first guide structures 2118 through the second guide structures 225 to move relative to the fixing member 211 along a first direction D1. For example, each first guide structure 2118 may be a strip-shaped groove, while each second guide structure 225 may be a protruding pillar structure, and each protruding pillar structure can slide in the corresponding strip-shaped groove.

[0036] Through the design of the first guide structure 2118 and the second guide structure 225, when the slider 22 is operated and moves relative to the fixed member 211, the slider 22 will not wobble from side to side, but will move relatively straight along the first direction D1 (i.e., the length direction of the fixed member 211). This provides the user with a good operating feel and allows the user to move the slider 22 relative to the fixed member 211 more smoothly. The shape, setting position, size and number of the first guide structure 2118 and the second guide structure 225 included in the fixed member 211 and the slider 22 are not limited to those shown in the figure.

[0037] Each engaging component 23 is connected to the fixing component 21, and the engaging component 23 can be in an engaging position relative to the fixing component 21 (e.g., ...). Figure 8 (as shown) and a non-engaging position (as shown) Figure 6The fastener 211 moves between the slots (as shown). In practical applications, the fastener 211 also forms two guide slots 2113 in the receiving slot 2112. The engaging member 23 may have a body 231, two guide structures 232, and a guide portion 233, with two guide structures 232 formed on both sides of the body 231. The body 231, each guide structure 232, and the guide portion 233 may be generally rectangular. In practical applications, the body 231, the two guide structures 232, and the guide portion 233 may be integrally formed.

[0038] Two guide structures 232 are slidably disposed in the two guide slots 2113 of the fixing member 211, and the engaging member 23 can cooperate with the two guide structures 232 and the two guide slots 2113 of the fixing member 211, thereby moving relative to the fixing member 211 along a second direction D2. The second direction D2 is not parallel to the first direction D1. Through the design of the guide structures 232 and the guide slots 2113, it can be ensured that the engaging member 23 can move stably along the second direction D2 when operated.

[0039] A guide portion 233 is formed at one end of the main body 231. A guide slope 2331 may be formed at one end of the guide portion 233, and a second engaging structure 234 may be formed on the inner side of the other end of the guide portion 233 (i.e., the side facing the main body 231). The second engaging structure 234 can engage with the adjacent first engaging structure 121.

[0040] The body 231, opposite to the end connected to the guide part 233, can be recessed to form a groove 2311 and a locking hole 2312. The periphery of the fixing member 211 is also recessed to form a limiting groove 2119, and the fixing member 211 also includes a through hole 2120, which penetrates the fixing member 211, and the through hole 2120, the limiting groove 2119 and the receiving groove 2112 are interconnected.

[0041] The auxiliary component 213 includes a body 231 and a stop portion 2132. The body 231 has a hollow channel 21311 that extends through the body 231. A portion of the body 231 passes through the through hole 2120 and is located in the groove 2311 of the engaging component 23, and the hollow channel 21311 communicates with the locking hole 2312 of the engaging component 23. One end of the auxiliary member 213 has an abutting part 2132. The outer diameter of the abutting part 2132 is larger than the outer diameter of the body 231, and the outer diameter of the abutting part 2132 is larger than the inner diameter of the through hole 2120 of the fixing member 211. The outer diameter of the body 231 of the auxiliary member 213 is not larger than the inner diameter of the through hole 2120 of the fixing member 211. A part of the auxiliary member 213 can be inserted into the fixing member 211 through the through hole 2120 from the outside of the engaging member 23, and the abutting part 2132 can abut against the wall of the fixing member 211 to form a limiting groove 2119.

[0042] When the abutting part 2132 of the auxiliary member 213 abuts against the wall of the limiting groove 2119 formed by the fixing member 211, the through hole 2120 of the fixing member 211, the hollow channel 21311 and the locking hole 2312 of the engaging member 23 are interconnected, and a screw A can be locked by passing through the through hole 2120, the hollow channel 21311 and the locking hole 2312, thereby preventing the engaging member 23 from disengaging from the fixing member 211, but the engaging member 23 can be operated to move relative to the fixing member 211 in the second direction D2.

[0043] One end of the elastic element 24 is fixed to the fixing element 211, and the other end of the elastic element 24 is fixed to the engaging element 23. When the engaging element 23 is operated and moves closer to the fixing element 211, the elastic element 24 will be compressed and generate an elastic restoring force. When the engaging element 23 is no longer operated, the elastic restoring force of the elastic element 24 will cause the engaging element 23 to return to its unoperated state. In practical applications, the elastic element 24 can be a compression spring, which can be sleeved on the periphery of the auxiliary element 213. One end of the compression spring can be fixed to the side of the fixing element 211 opposite to the side forming the limiting groove 2119, and the other end of the compression spring is fixed to the engaging element 23. A portion of the compression spring can be correspondingly located in the groove 2311 of the engaging element 23.

[0044] Please refer to the following: Figure 2 , Figure 6 , Figure 7 and Figure 8 , Figure 7 This is a partially enlarged schematic diagram showing the sliding components of the bracket of the present invention in fixed positions. Figure 8 This is a cross-sectional schematic diagram showing the sliding member of the bracket of the present invention in a fixed position. Figure 2 and Figure 6 As shown, when the second positioning structure 222 of the slider 22 (i.e. the protrusion of the elastic arm 224) and the third positioning structure 2117 of the fixing member 211 (i.e. one of the recesses of the fixing member 211) engage with each other, and the slider 22 is in the unlocked position and the slider 22 does not obstruct the engaging member 23, the engaging member 23 will be in the non-engaged position accordingly, and there is a gap between the second engaging structure 234 of the engaging member 23 and any of the adjacent first engaging structures 121. At this time, the fixing component 21 can be operated to rotate relative to the fixing base 1.

[0045] Furthermore, when the engaging member 23 is in the non-engaged position, the elastic member 24 is in an uncompressed state, and the guide portion 233 of the engaging member 23 protrudes from the periphery of the fixing member 211 and the sliding member 22, while the guide slope 2331 of the guide portion 233 is provided adjacent to one end of the sliding member 22. In addition, when the sliding member 22 is in the unlocked position, the second limiting structure 221 of the sliding member 22 abuts against the first limiting structure 2115 of the fixing member 211, and the user cannot easily move the sliding member 22 away from the fixing base 1.

[0046] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, when the slider 22 is operated and moves from the unlocked position to the fixed position relative to the fixed member 211 along the first direction D1, the second positioning structure 222 of the slider 22 will engage with the first positioning structure 2116 of the fixed member 211. The end of the slider 22 adjacent to the guide portion 233 will drive the guide slope 2331 of the guide portion 233, and the engaging member 23 will thus move relative to the fixed member 211 in the second direction D2 until the guide portion 233 is housed within the slider 22. At this time, the engaging member 23 will change from a non-engaged position to an engaged position, and the second engaging structure 234 will engage with the adjacent first engaging structure 121.

[0047] like Figure 8 As shown, when the engaging member 23 is in the engaged position and the outer periphery of the guide portion 233 of the engaging member 23 is housed within the sliding member 22, the elastic member 24 will be under pressure. The elastic restoring force generated by the pressure on the elastic member 24 will cause the engaging member 23 to move outward, thereby causing the outer periphery of the guide portion 233 to tightly abut against the inner side of the sliding member 22. This strengthens the connection between the engaging member 23 and the sliding member 22, making the second engaging structure 234 and the first engaging structure 121 more securely engaged. In other words, the sliding member 22, located in a fixed position, can stably engage with the first engaging structure 121 and the second engaging structure 234 not only through the second limiting structure 221 and the first limiting structure 2115, but also with the assistance of the elastic member 24.

[0048] Furthermore, when the slider 22 is in the fixed position, the engaging member 23 is in the engaging position, and the second limiting structure 221 engages with the first limiting structure 2115, and the second engaging structure 234 engages with the first engaging structure 121, and the engaging member 23 is housed inside the slider 22, the fixing component 21 will not be able to rotate relative to the fixing base 1, and the fixing component 21 and the fixing base 1 will be fixed at a specific angle. At this time, the user can fix devices such as cameras, video cameras, and lamps onto the fixing base 1.

[0049] like Figure 8 and Figure 6 As shown, when a user wants to change the angle between the fixed base 1 and the fixed component 21, the user only needs to apply force to the slider 22 to move the slider 22 away from the fixed base 1 along the first direction D1 until the second limiting structure 221 and the third positioning structure 2117 engage with each other. When the slider 22 is moved to the unlocked position, the inner side of the slider 22 will no longer abut against the outer periphery of the guide part 233 of the engaging member 23, and the engaging member 23 will automatically move away from the fixed member 211 along the second direction D2 under the action of the elastic member 24. In this way, the second engaging structure 234 will automatically stop engaging with the first engaging structure 121. At this time, the user can readjust the angle between the fixed component 21 and the fixed base 1.

[0050] In other words, when the slider 22 is in the unlocked position, the elastic restoring force generated by the compression of the elastic member 24 will cause the engaging member 23 to return to the position when it was not driven by the slider 22 (i.e., the non-engaged position), and the second engaging structure 234 will move away from the first engaging structure 121 so that it no longer engages with the first engaging structure 121.

[0051] In short, the user only needs to operate the slider 22, and the second engaging structure 234 of the engaging member 23 will automatically de-engage with the first engaging structure 121. The user can then operate the fixing component 21 to change the angle between the fixing component 21 and the fixing base 1. After the user adjusts the angle of the fixing component 21 and the fixing base 1, the user can also simply operate the slider 22 to drive the engaging member 23, thus making the second engaging structure 234 engage with the adjacent first engaging structure 121.

[0052] It should be emphasized that in embodiments where each support component 2 does not include the elastic element 24, when the user moves the slider 22 to the unlock position, the engaging component 23 will not automatically move away from the fixing component 211. However, the user can still operate the engaging component 23 to make the second engaging structure 234 of the engaging component 23 no longer fixed to the first engaging structure 121.

[0053] In summary, the bracket of the present invention, through its design of a fixed base, engaging components, and sliding components, allows users to easily fix the fixed components and fixed base together by simply operating the sliding component after adjusting the angle between them, thus completing the bracket setup. Conversely, when users want to readjust the angle between the fixed components and fixed base, they only need to operate the sliding component again and, in conjunction with the engaging component or the elastic component, disengage the second engaging structure of the engaging component from the first engaging structure, thereby allowing the fixed components to be adjusted relative to the fixed base. In other words, the bracket of the present invention allows users to easily adjust the angles between the various support components and the fixed base.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the description and drawings of the present invention are included within the protection scope of the present invention.

The bracket according to claim 1, characterized in that, The engaging component includes a guide ramp; during the process of the sliding component moving from the unlocked position to the fixed position relative to the fixed component along a first direction, one end of the sliding component will drive the guide ramp, causing the engaging component to move relative to the fixed component in a second direction; the second direction is not parallel to the first direction.

8. The bracket according to claim 1, characterized in that, Each of the fixing components includes a fixing member and a support foot. One end of the fixing member is pivotally connected to the fixing base, and the other end of the fixing member has a first limiting structure. The end of the sliding member away from the fixing base has a second limiting structure. The second limiting structure can abut against the first limiting structure, and the first limiting structure and the second limiting structure can jointly limit the range of motion of the sliding member relative to the fixing member. The fixing member is fixed to one end of the support foot, and the other end of the support foot is used to abut against the bearing surface.

9. The bracket according to claim 8, characterized in that, The periphery of the fixing member includes at least one first guide structure, and the inner side of the sliding member includes at least one second guide structure. The sliding member can move relative to the fixing member along a first direction by cooperating with the first guide structure through the second guide structure.

10. The stent according to claim 1, characterized in that, The engaging member is movable between a non-engaged position and an engaged position. When the engaging member is in the non-engaged position, there is a gap between the second engaging structure and any one of the adjacent first engaging structures, and the fixing component can be operated to rotate relative to the fixing base. When the sliding member is in the fixed position and the engaging member is in the engaged position, the second engaging structure engages with the adjacent first engaging structure, and the fixing component cannot rotate relative to the fixing base.
