Description
A CLAMPING DEVICE FOR MOUNTING A LOUDSPEAKER TO A PLATE MEMBER AND A LOUDSPEAKER APPARATUSTECHNICAL FIELD
[0001] The present disclosure relates to a clamping device for mounting a loudspeaker apparatus to a plate member and a loudspeaker apparatus.BACKGROUND
[0002] Loudspeakers are used in various applications, and in buildings, they can be installed in different ways. The speakers can be mounted in the ceiling, for example. In such cases, a hole is made in the ceiling and the loudspeaker is accommodated in a housing whose main part is smaller in diameter than the hole, and which has a flange with a widened radius at the bottom of the housing, wherein the flange is dimensioned larger than the diameter of the hole. The housing is equipped with clamping means, such as dogear clips, which can move and pivot in guide member, switching between retracted and extended positions. In order to mount the loudspeaker at the ceiling, the housing together with the speaker inside, is first passed underneath the ceiling through the hole, whereupon the clamping member is retracted, thereby allowing the housing to pass through the hole. Then, the clamping member is driven downwards and extended outwardly with the aid of self-tapping screws so as to be able to clamp the both sides of the ceiling with the cooperation of the clamping members with the flanges, thus fixing the housing together with the loudspeaker inside it at the ceiling.
[0003] However existing designs of the mounting device are not always satisfactory. First of all, the range of ceiling thicknesses is quite narrow due to the length restriction of the self-tapping screws. For thicker ceilings, the dogear clips must be replaced with adapters. Moreover, the ends of the screws are not fixed, so when the dogear clips approach the screw tops to clamp the ceiling, there is a risk of falling out of channels for the clips. Additionally, over-rotating the screws can cause the dogear clips to fall off the screws and channels.
[0004] Therefore, the technical problem to be solved by the present invention is to provide a clamping device which allows reliably and easily mounting a ceiling loudspeaker.SUMMARY

[0026] The disclosure can be better understood with reference to the following drawings and description. The components in the drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the disclosure. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
[0027] As used herein, the singular forms “a” , “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises” , “comprising” , “includes” , and / or “including” , as used herein, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. As used herein, the term “and / or” and the symbol “ / ” are meant to include any and all combinations of one or more of the associated listed items. Additionally, while the terms first, second, etc. may be used herein to describe various elements, components, steps or calculations, these elements, components, steps or calculations should not be limited by these terms, rather these terms are only used to distinguish one element, component, step or calculation from another. For example, a first component could be termed a second component, similarly a first calculation could be termed a second calculation; similarly a first step could be termed a second step; all without departing from the scope of this disclosure.
[0028] According to one aspect of the present disclosure, a clamping device for mounting a loudspeaker apparatus to a plate member is provided, wherein the loudspeaker apparatus comprises a housing for accommodating a loudspeaker comprising a circumferential wall and a mounting flange extending outwardly from the circumferential wall, wherein the clamping device comprises: a guide member fixedly connected to the housing and extending longitudinally along a height direction of the housing; a clamping means comprising a driving section and a clamping section; and a driving screw passing through the driving section of the clamping means, enabling a movement of the clamping means along the height direction in the guide member through a rotation of the driving screw; wherein the guide member comprises a first edge and a second edge opposed to each other, wherein the clamping means abuts against the first edge when the clamping means moves upward along the height direction, and the clamping means abuts against the second edge when the clamping means moves downward along the height direction, wherein the first edge includes a base segment and a recessed segment located above the base segment in the height direction and retracted towards the housing with respect to the base segment.
[0029] A hole is made in the ceiling and the loudspeaker is accommodated in a housing which has a main body whose dimensions are smaller than the diameter of the hole, and which has a mounting flange with a widened radius at the bottom of the housing, wherein the mounting flange is dimensioned larger than the diameter of the hole. In the prior art, the housing is equipped with clamping means, such as dogear clips, which can move and pivot in guide member, switching between retracted and extended positions. However, the range of upward movement of the clamping means is limited, suitable only for thinner ceilings. For thicker ceilings, the dogear clips must be replaced with adapters. Compared to this unfavorable design and cumbersome installation process, the clamping device of the present disclosure is suitable for a wider range of ceiling thicknesses. Specifically, the first edge of the guide member, against which the clamping means abuts when moving upward, is at least divided into a base segment below and a recessed segment above. The recessed segment is retracted inward with respect to the base segment, allowing the clamping means to retract and move further upward. This enables the clamping device to clamp thicker ceilings without replacing the clamping means, simplifying the installation process.
[0030] According to one or more embodiments of the present disclosure, the driving screw is constructed as a self-tapping screw. The driving section and the clamping section of the clamping means are integrally or rigidly connected, with the driving section arranged in the guide member and the clamping section extending outwardly from the guide member. The driving section of the clamping means is frictionally engaged with the driving screw, allowing the clamping means to pivot between a retracted state, in which the clamping section abuts against the recessed segment of the first edge, and an extended state, in which the clamping section abuts against the second edge.
[0031] According to the present disclosure, rotating the self-tapping screw in one rotation direction can transform the clamping means from the retracted state to the extended state based on the frictional engagement between the driving section of the clamping means and the self-tapping screw. When continuing to rotate the self-tapping screw in the same rotation direction, the clamping means, already abutting the second edge, moves downward driven by the self-tapping screw. Conversely, rotating the self-tapping screw in an opposite rotation direction transforms the clamping means from the extended state to the retracted state while moving upward along the first edge.
[0032] According to one or more embodiments of the present disclosure, the clamping section comprises an auxiliary segment on a side facing the second edge of the guide member, thereby the auxiliary segment abutting the second edge in the extended state of the clamping means. Preferably, the auxiliary segment is constructed as reinforcing a rib extending longitudinally in the height direction. This provides stable support for the clamping section in the extended state.
[0033] According to one or more embodiments of the present disclosure, the clamping section comprises multiple protrusions on its bottom surface, which oppose the mounting flange in the extended state of the clamping means. As a result, it is possible to increase the friction between the clamping section of the clamping means and the mounting flange of the housing, further improving the functional stability of the clamping device.
[0034] According to one or more embodiments of the present disclosure, the clamping means is formed from an elastic material. Preferably, the entire clamping device is made of plastic. This facilitates the mating action of the clamping means with the self-tapping screw.
[0035] According to one or more embodiments of the present disclosure, the clamping device comprises an end cap fixedly connected to a top of the guide member. An upper opening of the guide member is closed by means of the end cap, thus effectively preventing accidental dislodgement of the clamping means from the screw and the guide member.
[0036] According to one or more embodiments of the present disclosure, the first edge comprises a transition segment, wherein the transition segment is located between the base segment and the recessed segment and is constructed at least partially downwardly inclined. This prevents self-locking during the transition of the clamping means between the retracted and the extended states, thereby ensuring reliable functionality of the clamping device.
[0037] According to one or more embodiments of the present disclosure, the plate member is a ceiling. Of course, the plate member can also be the top of other spaces, such as the roof of a car.
[0038] In addition, another aspect of the present disclosure relates to a loudspeaker apparatus comprising a loudspeaker and the above-mentioned clamping device. The number of the clamping devices can be varied according to the design needs. It is possible, for example, to provide three, four or more clamping devices on the housing.
[0039] FIG. 1 schematically illustrates a loudspeaker apparatus according to an embodiment of the present disclosure, which is constructed, for example, as a ceiling loudspeaker. The loudspeaker apparatus comprises clamping devices 10, a housing 20 as shown in FIG. 1 and a loudspeaker not visible in figure.
[0040] The housing 20 is constructed substantially cylindrically. As shown in FIG. 1, the housing 20 comprises a circumferential wall 22 and a mounting flange 24 projecting outwardly with respect to the circumferential wall 22. Furthermore, the housing 20 comprises a mounting base 26 between the circumferential wall 22 and the mounting flange 24, which together with the circumferential wall 22 and the mounting flange 24 define an interior space, in which the loudspeaker is arranged. The loudspeaker works in a known manner and is not described herein.
[0041] Three clamping devices 10 are provided adjacent to the circumferential wall 22 of the housing 20. Each of the clamping devices 10 is capable of lifting and lowering in a height direction z with respect to the housing 20 so that the ceiling is clamped by the cooperating action of the clamping device 10 with the mounting flange 24. Three clamping devices 10 are uniformly spaced and distributed at equal angular intervals along the circumferential wall 22. As a result, a reliable installation of the loudspeaker apparatus can be guaranteed.
[0042] The clamping device 10 comprises a guide member 12, a clamping means 14 and a driving screw 16 constructed as a self-tapping screw.
[0043] The guide member 12 extends longitudinally along the height direction z of the housing 20, wherein a lower end of the guide member 12 is arranged on the mounting base 26 of the housing 20, while its upper end is closed by an end cap 18. In this case, a threaded hole is provided on the upper end surface of the guide member 12, and the end cap 18 is secured to the upper end of the guide member 12 with the aid of a mounting screw 32. As shown in FIG. 2, the guide member 12 has a substantially curved inner wall and includes a first edge 122 and a second edge 124 opposed to each other.
[0044] As shown in FIG. 3, the first edge 122 of the guide member 12 comprises a base segment 122a and a recessed segment 122b, which is located above the base segment 122a in the height direction z and retracted towards the housing 20 with respect to the base segment 122a. That is, the base segment 122a protrudes outwardly farther than the recessed segment 122b. The first edge 122 comprises a transition segment 122c, which is located between the base segment 122a and the recessed segment 122b and is constructed at least partially downwardly inclined. Therefore, a substantially L-shaped opening is formed by the base segment 122a, the recessed segment 122b and the transition segment 122c. The second edge 124 extends linearly in the height direction z.
[0045] The drive screw 16 extends between the lower end and an upper end of the guide member 12, wherein the head of the drive screw 16 is disposed on a bottom surface of the housing 20 so as to be operated from below, while the end of the driving screw 16 passes the end cap 18 and is tightened by the crown nut 30, wherein a washer34 and a spring ring 36 are arranged between the crown nut 30 and the end cap 18.
[0046] As shown in FIG. 4, the clamping means comprises a driving section 142 and a clamping section 144. The driving section 142 and the clamping section 144 are constructed integrally from a plastic material, wherein the driving section 142 has an arcuate cross-section and is provided with a center bore, and the clamping section 144 protrudes outwardly from the driving section 142. In the embodiment shown in FIG. 4, the clamping section 144 has a greater thickness in the height direction z than the driving section 142. In embodiments not shown, the clamping section 144 may also have the same thickness as the driving section 142 for thicker ceilings. The clamping section 144 is nested in the guide member 12, while the clamping section 144 protrudes outwardly from the guide member 12.
[0047] The driving screw 16 passes the center bore of the driving section 142 and is friction fit connected to the inner wall of the center bore so that pivoting of this clamping means 14 is achieved by rotation of the driving screw 16. For example, in the embodiment, by rotating the driving screw 16 in a first rotation direction R1 the clamping means 14 is rotated with the driving screw toward the first edge 122 until the clamping section 144 thereof abuts against the first edge 122, wherein when the clamping section 144 abuts against the recessed segment 122b of the first edge 122, the clamping section 144 is close to the circumferentially wall 22 of the housing 20, and is thus in the retracted state as shown in FIG. 1 and FIG. 7; the clamping means 14 is rotated with the driving screw toward the second edge 124 by rotating the driving screw 16 in a second rotation direction R2 opposite to the first rotation direction R1 until the clamping section 144 thereof rests against the second edge 124, wherein the clamping section 144 protrudes outwardly to the greatest extent possible, thereby the clamping means 14 is in the extended state as shown in FIGS. 5 and 6.
[0048] In addition, by a cooperating action of the male thread of the driving screw 16 with the clamping section 144, it is also possible to realize movement of the clamping means 14 in the height direction z when the free rotation of the clamping means 14 is limited. The driving screw 16 itself cannot move in the height direction z due to the limitations of its head, but can only rotate. When the clamping means 14 can no longer rotate freely, continued rotation of the driving screw 16 causes a movement of the clamping member 14 in the height direction z. The relationship between the rotation direction of the driving screw 16 and the direction of movement of the clamping means 14 in the height direction z depends on the direction of rotation of the threads. In this embodiment, for example, rotation of the driving screw 16 in the first rotation direction R1 may result in a rise of the clamping means 14; rotation of the driving screw 16 in the second rotation direction R2 may result in a fall of the clamping means 14.
[0049] In the illustrated embodiment, the self-tapping screw 16 is frictionally engaged with the clamping means 14. When the screw 16 is rotated, if the clamping means 14 is not obstructed or stopped by a structure, it rotates together with the screw 16. However, if obstructed or stopped (for example, by the first edge 122 or the second edge 124 of the guide member 12) , the clamping means 14 does not rotate with the screw 16, but instead moves up or down along the threads of the screw 16 during its rotation.
[0050] During operation, when the ceiling thickness is less than the distance between the clamping means 14 and the mounting flange 24, rotating the screw 16 in the second rotation direction R2 causes the clamping means 14 to abut against one of the edges, for example the second edge 124. At this point, the clamping means 14 moves downward along the threads of the screw 16, clamping the ceiling securely between the clamping means 14 and the mounting flange 24. On the other hand, if the ceiling thickness is greater than the initial distance between the clamping means 14 and the mounting flange 24, rotating the screw 16 in the first rotation direction R1 which is opposite to the second rotation direction R2, causes the clamping means 14 to abut against the other of the edges, for example the first edge 122. This causes the clamping means 14 to move upward, increasing the distance between the clamping means 14 and the mounting flange 24. Once the distance is sufficiently increased to accommodate the ceiling thickness, rotating the screw 16 in the second rotation direction R2 again causes the clamping means 14 to move downward, thereby securely clamping the ceiling.
[0051] Generally, ceilings have a thickness less than the initial distance between the clamping means 14 and the mounting flange 24, allowing for a straightforward clamping by simply rotating the screw 16 in the second rotation direction. For thicker ceilings, the procedure involves initially rotating the screw 16 in the first rotation direction to increase the gap, followed by a rotation in the second rotation direction to achieve secure clamping, simplifying the installation process.
[0052] While in the embodiments shown, the screw 16 is described as a self-tapping screw, it is not limited to this type and may include any suitable screw, as long as there is sufficient friction between the screw 16 and the clamping means 14. The clamping means 14 will rotate with the screw 16 when unobstructed by external forces. However, when obstructed by sufficient external force, the clamping means 14 does not rotate with the screw 16, but moves up or down along the screw’s threads.
[0053] To ensure the functional reliability and stability of the clamping device 10, an auxiliary segment 1442 is provided on the side of the clamping section 144 toward the second edge 124 of the guide member 12. As shown in FIG. 5, the auxiliary segment 1442 is constructed as a reinforcing rib extending along the height direction z, wherein the auxiliary segment 1442 rests against that second edge 124 when that clamping means 14 is in the extended state, thereby optimizing the distribution of force and improving the stability of the clamping means 14. In additional, the clamping section 144 comprises multiple protrusions 1444 on its bottom surface. In the extended state of the clamping means 14 the protrusions oppose the mounting flange 24, thereby improving the friction between the clamping section 144 and the mounting flange 24.
[0054] The following describes the operation of the clamping device 10 with reference to FIGS. 1, 5, 6 and 7.
[0055] When it is necessary to clamp a thinner ceiling with the clamping device 10, it is initially in the first starting position as shown in FIG. 1. At this time, the clamping means 14 is supported on the transition segment 122c between the base segment 122a and the recessed segment 122b of the first edge 122, with the clamping section 144 abutting the recessed segment 122b. The clamping means 14 is thus in the retracted state. Currently, the upper portion of the housing 20 and the clamping device 10 can pass through the mounting hole opened in the ceiling and be positioned above the ceiling, while the mounting flange 24 of the housing 20 remains below the ceiling.
[0056] Then, for example, when the driving screw 16 is rotated in the second rotation direction R2, it drives the clamping means 14 to pivot until its clamping section 144 abuts the second edge 124 of the guide member 12, reaching the extended state of the clamping means 14, as shown in FIG. 5.
[0057] At this time, if the driving screw 16 continues to be rotated in the second rotational direction R2, the clamping means 14 moves downward until its clamping section 144 clamps the ceiling from both sides with the mounting flange 24, reaching the final position of the clamping device 10, as shown in FIG. 6.
[0058] When it is necessary to release the clamping device 10 from the ceiling, the driving screw 16 is rotated in the first rotation direction R1, causing the clamping section 144 to abut the base segment 122a of the first edge 122 and move upward along the base segment 122a. The clamping section 144 then moves through the transition segment 122c to the recessed segment 122b, thereby abutting the recessed segment 122b. Thus the clamping means 14 switches from the extended state to the retracted state, allowing the clamping device 10 to be released from the ceiling.
[0059] When it is necessary to clamp a thicker ceiling with the clamping device 10, it is initially in the first starting position as shown in FIG. 1. At this time, the driving screw 16 is rotated in the first rotation direction R1, causing it to move upward along the recessed segment 122b of the first edge 122 until reaching the second starting position shown in FIG. 7, in which a distance between the clamping section 144 and the mounting flange 24 is greater, suitable for clamping thicker ceiling.
[0060] Then, by rotation of the driving screw 16 in the second rotation direction R2, the clamping means 14 is driven to pivot until its clamping section 144 abuts the second edge 124 of the guide member 12, reaching the extended state of the clamping means 14. Then the driving screw 16 continues to be rotated in the second rotational direction R2, the clamping means 14 moves downward until its clamping section 144 clamps the ceiling from both sides with the mounting flange 24, reaching the final position of the clamping device 10, as shown in FIG. 6.
