Description

Technical Field

[0001] The present invention relates to screw joint arrangements and devices comprising at least one such screw joint arrangement. In particular, the present invention relates to a screw joint arrangement for fixing a first member and a second member to each other.

Background Art

[0002] Screw joint arrangements are often used to fix two members to each other by screws.

[0003] A common problem associated with screw joint arrangements is the risk of the screw falling out during handling.

[0004] To fix the screw to one of the members, screw joint arrangements with some kind of retainer function are known. One such solution is disclosed in DE4243097A1.

[0005] Certain types of screw joint arrangements can adjust the position of two members relative to each other by loosening or re-tightening the screw joint arrangement.

[0006] The problem associated with this type of screw joint arrangement is the risk of the screw falling out during the adjustment process, especially when using a screw joint arrangement in an application located in a difficult-to-access position, which can be troublesome. An example could be a surveillance camera provided with such a screw joint arrangement and located on the ceiling of a room.

[0007] As a result, there is a need for an improved screw joint arrangement that provides a retainer function for the screw while also allowing the position of two members relative to each other to be adjusted.

Summary of the Invention

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

[0009] It is also an objective to provide a device that includes at least two such screw fitting arrangements.

[0010] To achieve at least one of the above objectives, and also to achieve other objectives that will become apparent from the following description, the present invention provides a screw coupling arrangement having the features defined in claim 1 and the apparatus described in claim 11. Several preferred embodiments will become apparent from the dependent claims.

[0011] More specifically, according to a first aspect of the present invention, a screw joint arrangement is provided comprising the following: A first member having at least one screw receiving portion, A second member having a bore comprising a first threaded bore portion, a second threaded bore portion, and a non-threaded bore portion separating the first threaded bore portion and the second threaded bore portion, and This is a screw comprising a screw head and a screw shaft on which a threaded portion is provided.

[0012] The first member is positioned next to the second member such that the first threaded bore portion of the bore of the second member is in close proximity to the first member. The screw joint configuration can be set by rotating the screw between a first state in which the second member is fixed to the first member and a second state in which the second member is movable relative to the first member. In the first state described above, one of at least one screw receiving portion of the first member and the bore of the second member are aligned, and the screw shaft extends into the bore with the screw portion screwed into the second threaded bore portion, passing through one of the at least one screw receiving portion, so that the first member is clamped between the screw head and the second member. In the second state described above, the screw shaft extends through the first threaded bore portion of the bore, and the threaded portion of the screw shaft is located within the unthreaded bore portion of the bore.

[0013] This provides an improved arrangement of threaded joints.

[0014] The screw joint configuration can be set between a first state and a second state by rotating the screw.

[0015] The first member and the second member are fixed to each other in a first state of the screw joint arrangement. More specifically, in the first state, one of at least one screw receptacles of the first member is aligned with the bore of the second member, and the screw shaft extends into the bore, with the screw portion threaded with the second threaded bore portion, passing through one of the at least one screw receptacles, so that the first member is clamped between the screw head and the second member. As a result, the first member and the second member can be firmly fixed to each other by setting the screw joint arrangement to the first state, that is, by tightening the screw.

[0016] The second member is movable relative to the first member in the second state of the threaded joint configuration. More specifically, in the second state, the screw shaft extends through the first threaded bore portion of the bore, and the threaded portion of the screw shaft is positioned within the unthreaded bore portion of the bore. This prevents the first member from being clamped between the second member and the screw head, while the threaded portion of the screw shaft is trapped within the unthreaded bore portion of the bore between the first and second threaded bore portions. As a result, the relative positions between the first and second members can be adjusted when the threaded joint configuration is set to the second state, i.e., by loosening the screw while ensuring that the screw cannot fall out.

[0017] According to one embodiment, the unthreaded bore portion of the bore may have a first length L1, and the threaded portion of the screw shaft may have a second length L2, wherein the first length L1 of the unthreaded bore portion is greater than the second length L2 of the threaded portion. This ensures that when the screw coupling arrangement is set to the second state, the threaded portion of the screw shaft can be firmly captured within the unthreaded bore portion of the bore.

[0018] According to another embodiment, the first member comprises two screw receivers, and the second member may be movable relative to the first member between a first position in which a portion of the screw shaft is positioned in one of the two screw receivers and a second position in which a portion of the screw shaft is positioned in the other of the two screw receivers, in a second state of the screw joint arrangement. Thus, the relative positions of the first member and the second member can be adjusted when the screw joint arrangement is in a second state in which the second member can move between a first position in which one of the two screw receivers is aligned with the bore of the second member and a second position in which the other of the two screw receivers is aligned with the bore of the second member.

[0019] Each of the two screw receiving portions may be provided with a lateral opening, and the second member may be movable relative to the first member between the first position and the second position by rotation around the axis in the second state of the screw joint arrangement.

[0020] The first member comprises first and second C-shaped sections facing each other, separated by a curved section, the first and second C-shaped sections being capable of forming the two screw receiving portions.

[0021] In yet another embodiment, the bore may be formed as an insert placed within a through-hole provided in the second member.

[0022] The insert may include a first part provided with a first threaded bore portion and a second part provided with a second threaded bore portion, and the insert may be assembled by concentrically inserting one of the first part and the second part into the other of the first part and the second part.

[0023] By providing the bore in the form of an insert, it becomes possible to form the first bore portion and the second bore portion of the bore from a first material such as a metallic material, and to form the second member from a second material such as a plastic material.

[0024] The insert may be placed in the through-hole by a mould-in process.

[0025] The insert can be profiled or stepped on its outer peripheral surface. This can facilitate fixing the insert within the second member when the insert is placed in the through-hole by a mould-in process.

[0026] According to a second aspect of the present invention, an apparatus is provided that includes at least one screw joint arrangement of the type described above.

[0027] According to one embodiment, the apparatus can be a camera device.

[0028] The first member may form part of the camera body of the camera device, and the second member may form part of the lens holder unit of the camera device. By setting at least one screw joint arrangement to a second state, the second member, i.e., the lens holder unit, can be moved relative to the first member, i.e., the camera body. Thereby, the orientation of the format of the camera device can be changed, for example, by rotating the camera's field of view by 90 degrees, the orientation can be changed from the corridor format orientation to the landscape format orientation.

[0029] In the second state of the screw joint arrangement, the second member can be moved relative to the first member between the first and second positions by rotating it around an axis corresponding to the optical axis of the lens holder unit.

[Modes for carrying out the invention]

[0033] The present invention will now be described more fully herein with reference to the accompanying drawings illustrating several current preferred embodiments of the invention. The invention may, however, be embodied in many different forms and should not be construed as being limited to the several embodiments described herein. Rather, these embodiments are provided to make the description thorough and complete and to fully convey the scope of the invention to those skilled in the art.

[0034] Referring to Figures 1a to 1c, the first member 100, the second member 200, and the screw 300 of the screw joint arrangement 1 according to the first embodiment are shown.

[0035] The first member 100 shown in Figure 1a may form part of a larger structure and may have any suitable form. In the illustrated embodiment, the first member 100 may be formed as a circular plate.

[0036] The first member 100 is provided with at least one screw receiving portion 101. In the illustrated embodiment, the first member 100 is provided with one centrally located screw receiving portion 101 in the form of a through hole 102.

[0037] The second member 200 shown in Figure 1b may form part of a larger structure and may have any suitable form. In the illustrated embodiment, the second member 200 may be formed as a rectangular plate.

[0038] The second member 200 is provided with a bore 201 comprising a first threaded bore portion 202, a second threaded bore portion 203, and an unthreaded bore portion 204 separating the first threaded bore portion 202 and the second threaded bore portion 203. In the illustrated embodiment, the bore 201 is a centrally located through bore that extends between the upper surface 205 and the lower surface 206 of the rectangular plate.

[0039] The non-threaded bore portion 204 of the bore 201 may have a first length L1.

[0040] The screw 300 shown in Figure 1c comprises a screw head 301 and a screw shaft 302 on which a threaded portion 303 is provided. In the illustrated embodiment, the threaded portion 303 is located at the distal end of the screw shaft 302.

[0041] The threaded portion 303 of the screw shaft 302 may have a second length L2.

[0042] The first length L1 of the non-threaded bore portion 204 may be greater than the second length L2 of the threaded portion 303.

[0043] Next, referring to Figures 2a and 2b, the screw joint arrangement 1 according to the first embodiment in an assembled state is shown.

[0044] The first member 100 is positioned next to the second member 200 such that the first threaded bore portion 202 of the bore 201 of the second member 200 is in close proximity to the first member 100.

[0045] In the illustrated embodiment, the first member 100 is positioned on top of the second member 200. In this case, the screw receiving portion 101 in the form of a through hole 102 of the first member 100 is aligned with the bore 201 of the second member 200.

[0046] The screw 300 is positioned within the through hole 102 and the bore 201. As a result, the first member 100 is positioned between the screw head 301 and the second member 200.

[0047] The screw joint arrangement 1 can be set between a first state in which the second member 200 is fixed to the first member 100 and a second state in which the second member 200 is movable relative to the first member 100 by rotating the screw 300.

[0048] In the first state shown in Figure 2a, one of at least one screw receiving portion 101 of the first member 100 is aligned with the bore 201 of the second member 200, and the screw shaft 302 extends into the bore 201 with the screw portion 303 threaded with the second threaded bore portion 203, passing through one of the at least one screw receiving portion 101, so 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 has only one screw receiving portion 101 in the form of a through hole 102, and as a result, the single screw receiving portion 101 in the form of a through hole 102 is aligned with the bore 201 of the second member 200.

[0049] The first state can be achieved by rotating the screw 300 to tighten the screw joint arrangement 1. Thereafter, the second member 200 is fixed to the first member 100.

[0050] In the second state shown in Figure 2b, the screw shaft 302 extends through the first threaded bore portion 202 of the bore 201, and the threaded portion 303 of the screw shaft 302 is located within the unthreaded bore portion 204 of the bore 201.

[0051] The fact that the length L1 of the unthreaded bore portion 204 of the bore 201 is greater than the second length L2 of the threaded portion 303 of the screw shaft 302 ensures that the threaded portion 303 of the screw shaft 302 can be fully accommodated within the unthreaded bore portion 204 of the bore 201.

[0052] The second state can be obtained by rotating the screw 300 to loosen the screw joint arrangement 1. Thereafter, the first member 100 is no longer clamped between the screw head 301 and the second member 200, thereby allowing the second member 200 to move relative to the first member 100.

[0053] Next, referring to Figure 3, we see the screw joint arrangement 1 according to the first embodiment in the second state.

[0054] 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 allows the first member 100 to rotate around axis X. This allows the marking on the first member 100 to move from a first position A to a second position B indicated on the second member 200.

[0055] In the illustrated embodiment, the screw receiving portion 101, which is in the form of a through hole 102 in the first member 100, remains aligned with the bore 201 of the second member 200 while the first member 100 is rotating.

[0056] When the screw coupling arrangement 1 is set to the second state, the threaded portion 303 of the screw shaft 302 is trapped within the unthreaded bore portion 204 of the bore 201 between the first threaded bore portion 202 and the second threaded bore portion 203. As a result, the relative position between the first member 100 and the second member 200 can be adjusted when the screw coupling arrangement 1 is set to the second state, that is, by loosening the screw 300 while ensuring that the screw 300 cannot fall out.

[0057] If you want to completely remove the screw 300 from the screw fitting arrangement 1, this can be done by using the first threaded bore portion 202 of the bore 201, that is, by loosening the screw 300 while the threaded portion 303 of the screw shaft 302 is threaded with the first threaded bore portion 202 of the bore 201.

[0058] As described above, the threaded joint arrangement may include two or more threaded receiving parts. Furthermore, the threaded joint arrangement of the present invention may be used in conjunction with further threaded joint arrangements.

[0059] Next, referring to Figure 4, a structure 2 comprising a first screw joint arrangement 1' and a second screw joint arrangement 1'' according to the second embodiment is shown. In this case, each of the first screw joint arrangement 1' and the second screw joint arrangement 1'' is provided with two screw receiving portions.

[0060] Structure 2 comprises a first member 100, a second member 200, and two screws 300.

[0061] The first member 100, shown in more detail in Figures 5a and 5b, has an annular shape and comprises a first pair of screw receiving portions 101 for the first screw joint arrangement 1' and a second pair of screw receiving portions 101 for the second screw joint arrangement 1''. As a result, the first member 100 of the first screw joint arrangement 1' is integrally formed with the first member 100 of the second screw joint arrangement 1'', that is, the two screw joint arrangements 1' and 1'' share a common first member 100.

[0062] 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 positioned on the peripheral edge of the first member 100.

[0063] The screw receiving portion 101 of the first screw joint arrangement 1' comprises a first C-shaped section 104 and a second C-shaped section 105. The first C-shaped section 104 and the second C-shaped section 105 face each other and are separated by a curved section 106.

[0064] Correspondingly, the screw receiving portion 101 of the second screw joint arrangement 1" comprises a first C-shaped section 107 and a second C-shaped section 108. The first C-shaped section 107 and the second C-shaped section 108 face each other and are separated by a curved section 109.

[0065] The second member 200, shown in more detail in Figures 6a and 6b, is provided with a bore 201 of the first threaded joint arrangement 1' at the peripheral portion of the second member 200 and a bore 201 of the second threaded joint arrangement 1” at the opposite peripheral portion of the second member 200.

[0066] Each bore 201 comprises a first threaded bore portion 202, a second threaded bore portion 203, and a non-threaded bore portion 204 that separates the first threaded bore portion 202 and the second threaded bore portion 203.

[0067] The non-threaded bore portion 204 of each bore 201 may have a first length L1.

[0068] In the illustrated embodiment, the lever 207 is positioned in the peripheral portion of the bore 201 of the first threaded joint arrangement 1'. The lever 207 extends radially outward.

[0069] The second member 200 of the first screw joint arrangement 1' is formed integrally with the second member 200 of the second screw joint arrangement 1'', that is, the two screw joint arrangements 1' and 1'' share a common second member 200.

[0070] The screws 300 are arranged within each bore 201. Each screw 300 comprises a screw head 301 and a screw shaft 302 on which a threaded portion 303 is provided. In the illustrated embodiment, the threaded portion 303 is located at the distal end of the screw shaft 302.

[0071] Each screw shaft 302 may have a second length L2 in its threaded portion 303.

[0072] The first length L1 of the non-threaded bore portion 204 may be greater than the second length L2 of the associated threaded portion 303.

[0073] In the illustrated embodiment, each bore 201, i.e., both the bore of the first threaded joint arrangement 1' and the bore of the second threaded joint arrangement 1'', are formed as inserts 208 positioned within their respective through holes 209 provided in the second member 200.

[0074] Insert 208 is shown in more detail in Figures 7a and 7b.

[0075] Each insert 208 comprises a first portion 210 having a first threaded bore portion 202 and a second portion 211 having a second threaded bore portion 203. The insert 208 is assembled by concentrically inserting one of the first portion 210 and the second portion 211 into the other of the first portion 210 and the second portion 211. In the illustrated embodiment, the first portion 210 is partially concentrically insertable into the second portion 211.

[0076] Each insert 208 may be positioned within its respective through-hole 209 by a molding process. The inserts 208 may be profiled or stepped on their outer surface to facilitate fixing them within the second member 200 when they are positioned within the through-hole 209 by the molding process.

[0077] The insert 208 may be made of metal.

[0078] The second member 200 may be made of plastic.

[0079] As shown in Figure 4, the first member 100 is positioned next to the second member 200. As a result, the first threaded bore portion 202 of both bores 201 of the first threaded joint arrangement 1' and the second threaded joint arrangement 1'' is in close proximity to the first member 100.

[0080] The first C-shaped sections 104, 107 of each threaded fitting arrangement 1', 1'' are aligned with the associated bore 201.

[0081] The screw 300 of the first screw joint arrangement 1' is shown with its screw shaft 302 extending into the bore 201 of the second member 200, passing through an associated screw receiving portion 101 in the form of a first C-shaped section 104 of the first member 100. The first screw joint arrangement 1' is set to a first state in which the threaded portion 303 of the screw shaft 302 is threaded with the second threaded bore portion 203 of the bore 201. Thereafter, the first member 100 is clamped between the screw head 301 and the second member 200. The first state can be achieved by rotating the screw 300 to tighten the first screw joint arrangement 1'.

[0082] The screw 300 of the second screw joint arrangement 1" is shown with its screw shaft 302 extending into the bore 201 of the second member 200, passing through a screw receiving portion 101 in the form of a first C-shaped section 107 of the second member 200. The second screw joint arrangement 1" is set to a second state in which the threaded portion 303 of the screw shaft 302 is positioned within the unthreaded bore portion 204 of the bore 201. As a result, in the second state of the second screw joint arrangement 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 joint arrangement 1".

[0083] As described above, the first member 100 and the second member 200 are shared by the first screw joint arrangement 1' and the second screw joint arrangement 1'', and as a result, both screw joint arrangements 1' and 1'' need to be set to the second state so that the second member 200 is movable relative to the first member 100.

[0084] Therefore, by setting the first and second screw joint arrangements 1', 1'' to the second state, the position of the second member 200 can be adjusted relative to the first member 100.

[0085] As described above, each threaded joint arrangement 1', 1'' comprises two threaded receptacles 101 in the form of first and second C-shaped sections 104, 105, 107, 108 that face each other. The position of the second member 200 can therefore be adjusted by rotating the second member 200 around axis X. Thereafter, the threaded shaft 302 of each threaded joint arrangement 1', 1'' is moved to exit the associated first C-shaped sections 104, 107 through the lateral opening 103. By continuously rotating the second member 200 relative to the first member 100, each threaded shaft 302 can be moved along the curved sections 106, 109 of the respective threaded receptacles 101 and enter the associated second C-shaped sections 105, 108 by entering through the lateral opening 103.

[0086] A lever 207 positioned on the periphery of the second member 200 can be used to rotate the second member 200 relative to the first member 100 around the axis X.

[0087] When the position between the first member 100 and the second member 200 is adjusted, the first and second screw joint arrangements 1', 1'' can be set to a first state by rotating the screw 300 to tighten the screw 300, thereby fixing the relative position between the first member 100 and the second member 200.

[0088] The device in the form of camera device 3 is provided with two screw fitting arrangements 1', 1'' which will be described with reference to Figures 4, 5a, 5b, 6a, 6b, 7a, and 7b, and will be described with reference to Figure 8. In Figure 8, the housing of camera device 3 has been removed for clarity.

[0089] The camera device 3 comprises a camera body 4 that supports a first camera unit 5 and a second camera unit 6. The first camera unit 5 (on the left in the figure) can be rotated to change the orientation of the camera device 3's format. Therefore, for example, the first camera unit 5 can be changed from a corridor format orientation to a landscape format orientation by rotating the camera's field of view by 90 degrees.

[0090] The first camera unit 5 includes a lens holder unit 7. The lens holder unit 7 is connected to the camera body 4 by two screw coupling arrangements 1' and 1''. The two screw coupling arrangements 1' and 1'' are shown in more detail in Figure 9. Figure 9 shows the first camera unit 5 with the cover plate removed for clarity.

[0091] The second member 200 of the two screw joint arrangements 1', 1'' forms part of the lens holder unit 7. More specifically, the ring-shaped second member 200 surrounds the lens barrel of the lens holder unit 7.

[0092] The first member 100 with two screw joint arrangements 1', 1'' forms part of the camera body 4.

[0093] When both screw joint arrangements 1' and 1'' are set to the first state, the position between the first member 100 and the second member 200 is locked, which means that the position between the lens holder unit 7 and the camera body 4 is fixed.

[0094] When both screw joint arrangements 1' and 1'' are set to the second state, the position between the first member 100 and the second member 200 can be adjusted, which means that the lens holder unit 7 can be moved 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 around an axis corresponding to the optical axis of the lens holder unit 7 relative to the first member 100 and the camera body 4.

[0095] The fact that the threaded portion 303 of each screw shaft 302 is captured inside the unthreaded bore portion 204 of the associated bore 201 in the second state of screw joint arrangement 1', 1'' as described above ensures that the position can be adjusted without the risk of the screw 300 falling out.

[0096] A lever 207 located on the second member 200 may be used to rotate the second member 200.

[0097] When the relative position between the lens holder unit 7 and the camera body 4 is adjusted, this position can be fixed again by setting the screw joint arrangement 1', 1'' to a first state.

[0098] It will be understood that the present invention is not limited to the illustrated embodiments. Therefore, several modifications and variations are conceivable within the scope of the invention, which is exclusively defined by the appended claims.
