Description

Technical Field

[0001] This invention relates to screw joint devices and devices including at least one such screw joint device. More specifically, this invention relates to screw joint devices for securing a first component and a second component to each other. Background Technology

[0002] Screw joints are typically used to fasten two components together with screws.

[0003] A common problem associated with screw-joint devices is the risk of screws coming loose during operation.

[0004] Screw joint devices with a retainer function are known for securing screws to one of components. One such solution is disclosed in DE4243097A1.

[0005] A certain type of screw joint device allows the position of two components relative to each other to be adjusted by loosening and retightening the screw joint device.

[0006] A problem associated with this type of screw-joint device is the risk of the screw coming loose during the adjustment process, which can be troublesome, especially if the screw-joint device is used in applications where it is placed in hard-to-access locations. An example could be a surveillance camera equipped with this type of screw-joint device and installed in the ceiling of a room.

[0007] Therefore, there is a need for an improved screw joint device that provides a retainer function for the screw while also allowing adjustment of the position of the two components relative to each other. Summary of the Invention

[0008] In view of the foregoing, one object of the present invention is to provide a screw joint device that has a retainer function for screws and also allows adjustment of the position between two components that are fixed to each other by means of the screw joint device.

[0009] Another object of the present invention is to provide a device comprising at least two such screw joint devices.

[0010] To achieve at least one of the above objectives, and others that will also be apparent from the following description, a screw joint device and apparatus having the following features are provided according to the present invention. Preferred embodiments will become apparent from the following description.

[0011] More specifically, according to a first aspect of the invention, a screw joint device is provided, comprising:

[0012] The first component is provided with at least one screw receiving portion;

[0013] A second component is provided with a hole, the hole including a first threaded hole portion, a second threaded hole portion, and a non-threaded hole portion separating the first threaded hole portion and the second threaded hole portion; and

[0014] A screw, including a screw head and a screw shank with threaded screw portions.

[0015] The first component is arranged adjacent to the second component, and the first threaded hole portion of the hole in the second component is close to the first component.

[0016] The screw connector can be set between a first state and a second state by rotating the screw. In the first state, the second component is fixed relative to the first component, and in the second state, the second component is movable relative to the first component.

[0017] In the first state, one of the at least one screw receiving portions of the first member is aligned with the hole of the second member, and the screw shank extends through the at least one screw receiving portion and into the hole, and the threaded screw portion engages the second threaded hole portion, such that the first member is clamped between the screw head and the second member.

[0018] In the second state, the screw shank extends through the first threaded portion of the hole, and the threaded screw portion of the screw shank is located in the non-threaded portion of the hole.

[0019] An improved screw joint device is provided herein.

[0020] The screw connector can be set between the first state and the second state by rotating the screw.

[0021] In the first state of the screw connector assembly, the first member and the second member are fixed relative to each other. More specifically, in the first state, one of the screw receiving portions of at least one screw receiving portion of the first member is aligned with a hole in the second member, and a screw shank extends through the screw receiving portion and into the hole, with the threaded screw portion engaging the second threaded hole portion, such that the first member is clamped between the screw head and the second member. Therefore, by setting the screw connector assembly in the first state, i.e., by tightening the screw, the first member and the second member can be securely fixed to each other.

[0022] In the second state of the screw connector, the second member is movable relative to the first member. More specifically, in the second state, the screw shank extends through the first threaded portion of the hole, and the threaded screw portion of the screw shank is located in the unthreaded portion of the hole. Here, the first member is not clamped between the second member and the screw head, while the threaded screw portion of the screw shank is captured in the unthreaded portion between the first and second threaded portions of the hole. Therefore, when the screw connector is set in the second state, i.e., by loosening the screw, the relative position between the first and second members can be adjusted while ensuring that the screw does not fall out.

[0023] According to one embodiment, the non-threaded portion of the hole may have a first length L1, and the threaded portion of the screw shank may have a second length L2, wherein the first length L1 of the non-threaded portion is greater than the second length L2 of the threaded portion. Here, it can be ensured that when the screw connector is set in the second state, the threaded portion of the screw shank can be easily captured in the non-threaded portion of the hole.

[0024] According to another embodiment, the first component may include two screw receiving portions, and in the second state of the screw connector device, the second component is movable relative to the first component between a first position and a second position. In the first position, a portion of the screw shank is located in one of the two screw receiving portions, and in the second position, the portion of the screw shank is located in the other of the two screw receiving portions. Here, when the screw connector device is in the second state, the positions of the first component and the second component relative to each other can be adjusted such that the second component can move between the first position and the second position. In the first position, one of the two screw receiving portions is aligned with a hole in the first component, and in the second position, the other screw receiving portion is aligned with a hole in the first component.

[0025] Each of the two screw receiving portions may be provided with a lateral opening, and in the second state of the screw joint assembly, the second member can be moved relative to the first member between the first position and the second position by rotating about an axis.

[0026] The first component may include a peripheral portion comprising a first C-shaped segment and a second C-shaped segment, the first C-shaped segment and the second C-shaped segment facing each other and separated by a curved segment, and the first C-shaped segment and the second C-shaped segment forming the two screw receiving portions.

[0027] According to yet another embodiment, the hole can be formed as an insert disposed in a through hole provided in the second member.

[0028] The insert may include a first component having the first threaded hole portion and a second component having the second threaded hole portion, and wherein the insert can be assembled by concentrically inserting one of the first component and the second component into the other of the first component and the second component.

[0029] By providing a hole in the form of an insert, it is possible to form a first hole portion and a second hole portion of the hole in a first material (such as a metallic material), and to form a second component in a second material (such as a plastic material).

[0030] The insert can be arranged in the through hole through a mold-in process.

[0031] The insert can be provided with a profiled or stepped outer envelope surface. This facilitates anchoring the insert in the second component when it is arranged in the through-hole via an in-mold process.

[0032] According to a second aspect of the invention, an apparatus is provided comprising at least one screw joint device of the type described above.

[0033] According to one embodiment, the device may be a camera device.

[0034] The first component can form part of the camera body of the camera device, and the second component can form part of the lens retainer unit of the camera device. By setting at least one screw joint device in a second state, the second component (i.e., the lens retainer unit) can be moved relative to the first component (i.e., the camera body), which can be used to change the format orientation of the camera device, such as changing from a corridor format orientation to a landscape format orientation by flipping the camera view by 90 degrees.

[0035] In the second state of the screw joint device, the first member can be moved between the first position and the second position by rotating about an axis corresponding to the optical axis of the lens retainer unit.

[0036] Generally, unless otherwise expressly defined herein, all terms used in the claims will be interpreted according to their ordinary meaning in the art. Unless otherwise expressly stated, all references to “a / the [element, device, component, manner, step, etc.]” ​​will be openly interpreted as referring to at least one instance of said element, device, component, manner, step, etc. Unless expressly stated otherwise, the steps of any method disclosed herein do not necessarily have to be performed in the exact order disclosed.

[0053] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for comprehensiveness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0054] In the reference Figures 1a to 1c The first component 100, the second component 200, and the screw 300 of the screw joint device 1 according to the first embodiment are illustrated.

[0055] exist Figure 1a The first component 100 shown can form part of a larger structure and can also have any suitable form. In the illustrated embodiment, the first component 100 can be formed as a circular plate.

[0056] The first component 100 is provided with at least one screw receiving portion 101. In the illustrated embodiment, the first component 100 is provided with a centrally located screw receiving portion 101 in the form of a through hole 102.

[0057] exist Figure 1b The second component 200 shown can form part of a larger structure and can also have any suitable form. In the illustrated embodiment, the second component 200 can be formed as a rectangular plate.

[0058] The second component 200 is provided with a hole 201, which includes a first threaded hole portion 202, a second threaded hole portion 203, and a non-threaded hole portion 204 separating the first threaded hole portion 202 and the second threaded hole portion 203. In the illustrated embodiment, the hole 201 is a through hole centrally located and extending between the top surface 205 and the bottom surface 206 of the rectangular plate.

[0059] The non-threaded portion 204 of hole 201 may have a first length L1.

[0060] exist Figure 1c The screw 300 shown includes a screw head 301 and a screw shank 302 provided with a threaded screw portion 303. In the illustrated embodiment, the threaded screw portion 303 is disposed at the distal end of the screw shank 302.

[0061] The threaded screw portion 303 of the screw rod 302 may have a second length L2.

[0062] The first length L1 of the non-threaded hole portion 204 can be greater than the second length L2 of the threaded screw portion 303.

[0063] The reference now Figure 2a and Figure 2b An example is shown of a screw joint device 1 according to the first embodiment in an assembled state.

[0064] The first component 100 is arranged adjacent to the second component 200, and the first threaded hole portion 202 of the hole 201 of the second component 200 is close to the first component 100.

[0065] In the illustrated embodiment, the first member 100 is disposed on top of the second member 200, and the screw receiving portion 101 in the form of a through hole 102 of the first member 100 is aligned with the hole 201 of the second member 200.

[0066] Screw 300 is arranged in through hole 102 and hole 201 such that first member 100 is arranged between screw head 301 and second member 200.

[0067] The screw connector 1 can be set between a first state and a second state by rotating the screw 300. In the first state, the second member 200 is fixed relative to the first member 100, and in the second state, the second member 200 can move relative to the first member 100.

[0068] exist Figure 2a In the first state illustrated, one of the screw receiving portions 101 of the first member 100 is aligned with the hole 201 of the second member 200, and a screw shank 302 extends through the one of the screw receiving portions 101 and into the hole 201, and a threaded screw portion 303 engages with a second threaded hole portion 203, such that the first member 100 is clamped between the screw head 301 and the second member 200. In the illustrated embodiment, the first member 100 includes only one screw receiving portion 101 in the form of a through hole 102, and therefore it is a through hole 102 aligned with the hole 201 of the second member 200.

[0069] The first state can be obtained by rotating the screw 300 to tighten the screw joint device 1, thereby fixing the second component 200 relative to the first component 100.

[0070] exist Figure 2b In the second state illustrated, the screw shank 302 extends through the first threaded hole portion 202 of the hole 201, and the threaded screw portion 303 of the screw shank 302 is located in the non-threaded hole portion 204 of the hole 201.

[0071] The fact that the length L1 of the non-threaded portion 204 of the hole 201 is greater than the second length L2 of the threaded portion 303 of the screw rod 302 ensures that the threaded portion 303 of the screw rod 302 can be completely contained within the non-threaded portion 204 of the hole 201.

[0072] The second state can be obtained by rotating the screw 300 to loosen the screw joint device 1 so that the first component 100 is no longer clamped between the screw head 301 and the second component 200, thereby enabling the second component 200 to move relative to the first component 100.

[0073] In the current reference Figure 3 In the first embodiment, the screw joint device 1 is shown in its second state.

[0074] As described above, in the second state, the second member 200 is movable relative to the first member 100. In the illustrated embodiment, this relative mobility enables the first member 100 to rotate about axis X, such that a mark on the first member 100 can be moved from a first position A indicated on the second member 200 to a second position B.

[0075] In the illustrated embodiment, during rotation of the first member 100, the screw receiving portion 101 in the form of a through hole 102 of the first member 100 remains aligned with the hole 201 of the second member 200.

[0076] When the screw connector 1 is set in the second state, the threaded screw portion 303 of the screw shank 302 is trapped in the non-threaded portion 204 between the first threaded hole portion 202 and the second threaded hole portion 203 of the hole 201. Therefore, when the screw connector 1 is set in the second state, i.e., by loosening the screw 300, the relative position between the first member 100 and the second member 200 can be adjusted, while ensuring that the screw 300 does not fall out.

[0077] If it is desired to completely remove the screw 300 from the screw head assembly 1, this can be achieved by using the first threaded hole portion 202 of the hole 201, that is, by unscrewing the screw 300 in the case of the threaded screw portion 303 of the screw shank 302 threadedly engaging the first threaded hole portion 202 of the hole 201.

[0078] As described above, the screw connector device may include more than one screw receiving portion. Furthermore, the screw connector device of the present invention can be used in conjunction with other screw connector devices.

[0079] In the current reference Figure 4 The diagram shows structure 2, which includes a first screw connector device 1' and a second screw connector device 1'' according to a second embodiment, wherein each of the first screw connector device 1' and the second screw connector device 1'' includes two screw receiving portions.

[0080] Structure 2 includes a first component 100, a second component 200, and two screws 300.

[0081] exist Figure 5a , Figure 5b The first component 100, shown in more detail, has an annular shape and includes a first pair of screw receiving portions 101 of the first screw connector device 1' and a second pair of screw receiving portions 101 of the second screw connector device 1''. Therefore, the first component 100 of the first screw connector device 1' and the first component 100 of the second screw connector device 1'' are integrally formed, that is, the two screw connector devices 1' and 1'' share a common first component 100.

[0082] Each screw receiving portion 101 is provided with a lateral opening 103. More specifically, each screw receiving portion 103 is formed as a C-shaped section disposed at the peripheral portion of the first member 100.

[0083] The screw receiving portion 101 of the first screw connector device 1' includes a first C-shaped section 104 and a second C-shaped section 105, which face each other and are separated by a curved section 106.

[0084] Correspondingly, the screw receiving portion 101 of the second screw connector device 1'' includes a first C-shaped section 107 and a second C-shaped section 108, which face each other and are separated by a curved section 109.

[0085] exist Figure 6a , Figure 6b The second member 200, shown in more detail, has an annular shape and is provided with a hole 201 for the first screw joint device 1' in the peripheral portion of the second member 200 and a hole 201 for the second screw joint device 1'' in the opposite peripheral portion of the second member 200.

[0086] Each hole 201 includes a first threaded hole portion 202, a second threaded hole portion 203, and a non-threaded hole portion 204 that separates the first threaded hole portion 202 and the second threaded hole portion 203.

[0087] The non-threaded portion 204 of each hole 201 may have a first length L1.

[0088] In the illustrated embodiment, the control lever 207 is arranged in the peripheral portion of the hole 201, which includes the first screw joint device 1'. The control lever 207 extends outward in the radial direction.

[0089] The second component 200 of the first screw joint device 1' is integrally formed with the second component 200 of the second screw joint device 1'', that is, the two screw joint devices 1' and 1'' share the common second component 200.

[0090] Screws 300 are disposed in each hole 201. Each screw 300 includes a screw head 301 and a screw shank 302 provided with a threaded screw portion 303. In the illustrated embodiment, the threaded screw portion 303 is disposed at the distal end of the screw shank 302.

[0091] The threaded screw portion 303 of each screw rod 302 may have a second length L2.

[0092] The first length L1 of the non-threaded hole portion 204 may be greater than the second length L2 of the associated threaded screw portion 303.

[0093] In the illustrated embodiment, each hole (i.e., the hole of the first screw connector 1' and the hole of the second screw connector 1'') 201 is formed as an insert 208, which is arranged in a corresponding through hole 209 provided in the second member 200.

[0094] Insert 208 in Figure 7a , Figure 7b It is shown in more detail below.

[0095] Each insert 208 includes a first component 210 having a first threaded hole portion 202 and a second component 211 having a second threaded hole portion 203. The insert 208 is assembled by concentrically inserting one of the first component 210 and the second component 211 into the other of the first component 210 and the second component 211. In the illustrated embodiment, the first component 210 can be concentrically partially inserted into the second component 211.

[0096] Each insert 208 can be arranged in a corresponding through hole 209 via an in-mold process. The insert 208 can be provided with a shaped or stepped outer envelope to facilitate anchoring the insert 208 in the second member 200 when the insert 208 is arranged in the through hole 209 via an in-mold process.

[0097] Insert 208 can be made of metal.

[0098] The second component 200 can be made of plastic material.

[0099] like Figure 4 As shown, the first member 100 is arranged adjacent to the second member 200 such that the first threaded hole portion 202 of the hole 201 of both the first screw connector 1' and the second screw connector 1'' is close to the first member 100.

[0100] The first C-shaped sections 104 and 107 of the corresponding screw joint devices 1' and 1'' are aligned with their associated holes 201.

[0101] The screw 300 of the first screw connector 1' is shown with its screw shank 302 extending through an associated screw receiving portion 101 in the form of a first C-shaped section 104 of the first member 100 and entering into a hole 201 of the second member 200. The first screw connector 1' is positioned in a first state in which the threaded screw portion 303 of the screw shank 302 threadedly engages the second threaded hole portion 203 of the hole 201, such that the first member 100 is clamped between the screw head 301 and the second member 200. The first state can be obtained by rotating the screw 300 to tighten the first screw connector 1'.

[0102] The screw 300 of the second screw connector 1'' is shown with its screw shank 302 extending through a screw receiving portion 101 in the form of a first C-shaped section 107 of the second member 200 and entering the associated hole 201 of the second member 200. The second screw connector 1'' is positioned in a second state in which the threaded screw portion 303 of the screw shank 302 is located in the unthreaded hole portion 204 of the hole 201. Therefore, in the second state of the second screw connector 1'', the first member 100 is not clamped between the screw head 301 and the second member 200. The second state can be obtained by rotating the screw 300 to loosen the second screw connector 1''.

[0103] As described above, the first component 100 and the second component 200 are shared by the first screw joint device 1' and the second screw joint device 2''. Therefore, both screw joint devices 1' and 1'' need to be set in the second state so that the second component 200 can move relative to the first component 100.

[0104] Therefore, by setting the first screw connector 1' and the second screw connector 1'' in the second state, the position of the second component 200 can be adjusted relative to the first component 100.

[0105] As described above, each screw connector 1', 1'' includes two screw receiving portions 101 in the form of first C-shaped sections 104, 107 and second C-shaped sections 105, 108 facing each other. Therefore, the position of the second member 200 can be adjusted by rotating the second member 200 about axis X, causing the screw shank 302 of each screw connector 1', 1'' to move out through its lateral opening 103 from the associated first C-shaped section 104, 107. With continued rotation of the second member 200 relative to the first member 100, each screw shank 302 can be moved along the curved sections 106, 109 of the corresponding screw receiving portion 101 and enters the associated second C-shaped section 105, 108 by entering through its lateral opening 103.

[0106] The control lever 207, arranged in the peripheral portion of the second member 200, can be used to rotate the second member 200 relative to the first member 100 about the axis X.

[0107] When the position between the first component 100 and the second component 200 has been adjusted, the first screw connector 1' and the second screw connector 1'' can be set in a first state by rotating the screw 300 to tighten it, thereby fixing the relative position between the first component 100 and the second component 200.

[0108] Now refer to Figure 8 The device described is of the form of camera device 3, which provides the above reference. Figure 4 , Figure 5a , Figure 5b , Figure 6a , Figure 6b , Figure 7a , Figure 7b The description refers to two screw-joint devices 1' and 1'' of the type described. For clarity, in... Figure 8 The casing of camera device 3 has been removed.

[0109] The camera device 3 includes a camera body 4 that supports a first camera unit 5 and a second camera unit 6. The first camera unit 5 (upper left in the figure) can be rotated to change the format orientation of the camera device 3. For example, the first camera unit 5 can be changed from a corridor format orientation to a landscape format orientation by flipping the camera viewpoint by 90 degrees.

[0110] The first camera unit 5 includes a lens retainer unit 7, which is connected to the camera body 4 by means of two screw connectors 1', 1''. Figure 9 It is shown in more detail in the middle. Figure 9 Example of a first camera unit 5, in which a cover plate has been removed to improve clarity.

[0111] The second member 200 of the two screw joint assemblies 1', 1'' forms part of the lens retainer unit 7. More specifically, the annular second member 200 surrounds the lens barrel of the lens retainer unit 7.

[0112] The first component 100 of the two screw joint devices 1' and 1'' forms part of the camera body 4.

[0113] When both screw connectors 1' and 1'' are set in the first state, the position between the first component 100 and the second component 200 is locked, which means that the position between the lens holder unit 7 and the camera body 4 is fixed.

[0114] When both screw connectors 1' and 1'' are in the second state, the position between the first member 100 and the second member 200 can be adjusted, meaning that the lens holder unit 7 can move relative to the camera body 4. In the illustrated embodiment, this movement is a rotational movement of the second member 200 and the lens holder unit 7 relative to the first member 100 and the camera body 4 about an axis corresponding to the optical axis of the lens holder unit 7.

[0115] In the second state of the screw connector 1', 1'' as described above, the fact that the threaded screw portion 303 of each screw shank 302 is trapped inside the non-threaded hole portion 204 of the associated hole 201 ensures that the position can be adjusted without the risk of the screw 300 falling out.

[0116] The control lever 207 arranged on the second component 200 can be used to rotate the second component 200.

[0117] When the relative position between the lens retainer unit 7 and the camera body 4 has been adjusted, the position can be fixed again by setting the screw connectors 1', 1'' in the first state.

[0118] It will be understood that the invention is not limited to the embodiments shown. Therefore, various modifications and variations are conceived within the scope of the invention as defined herein only by the appended claims.
