[0014] Further objects, features, and advantages of the present disclosure will appear from the following detailed description, wherein some aspects of the disclosure will be described in more detail with reference to the accompanying drawings, in which:

[0015] FIG. 1 schematically illustrates a speed ring according to an exemplary embodiment of the present disclosure.

DETAILED DESCRIPTION

[0016] Aspects of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. The devices and methods disclosed herein can, however, be realized in many different forms and should not be construed as being limited to the aspects set forth herein. Like numbers in the drawings refer to like elements throughout.

[0017] The general object or idea of embodiments of the present disclosure is to address at least one or some of the disadvantages with the prior art solutions described above as well as below. The various aspects described below in connection with the FIGURES should be primarily understood in a logical sense.

[0018] The terminology used herein is for the purpose of describing particular aspects of the disclosure only, and is not intended to limit the disclosure to any particular embodiment. 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.

[0019] FIG. 1 schematically illustrates a support ring 1 for mounting of a soft box on a light source. The support ring 1 comprises attachment means 2 for attachment of the support ring 1 to the light source. Further the support ring comprises at least one cavity 3 configured to receive support pins 4 of the soft box. According to an aspect of the present disclosure the cavity 3 further comprises a first 5 and a second 6 support element arranged to counteract a torque from the support pins, when the support pins are in an inserted position in the cavity; and at least one entry element 7 arranged on a radial outside of the cavity 3 and arranged to counteract a force required to bend the support pin to an angle where the support pin can be inserted into the cavity 3. The at least one cavity 3 can also be a space 3 that among others is narrowed by the first 5 and the second 6 support elements.

[0020] By providing the support ring 1 with at least one entry element 7 arranged on a radial outside of the cavity 3 and arranged to counteract a force required to bend the support pin to an angle where the support pin can be inserted into the cavity 3, it becomes much easier to insert the support pin 4 into the cavity 3 since the entry element 7 can counter the force from the support pin 4 when the support pin 4 is bent. Thus it is only required to pull the support pin 4 in order to bend the support pin 4 so that the support pin 4 can be inserted into the cavity 3.

[0021] The support ring 1 can be manufactured in many different materials. Preferably the support ring 1 is made of cast aluminium. An advantage with manufacturing the support ring 1 in cast aluminium is that the manufacturing process is easy which means that the support ring 1 can be produced at a low cost. Another advantage by manufacturing the support ring 1 in aluminium is that the support ring 1 becomes strong and light weight.

[0022] The cavity 3 in the support ring 1 may be embodied in many different ways. It is however important that the cavity has at least the first 5 and the second 6 support element arranged to counteract a torque from the support pins 4, when the support pins 4 are in an inserted position in the cavity 3. According to one aspect of the present disclosure is the cavity 3 cylinder shaped and has a diameter that is adapted to the diameter of the support pins 4.

[0023] According to one aspect of the present disclosure, in an embodiment where the cavity 3 is cylinder shaped, the first 5 and the second 6 support elements are inner wall sections of the cylinder 3.

[0024] According to another aspect of the present disclosure the cross section of the cavity 3 perpendicular to the radial direction is rectangular or quadratic. In this embodiment the dimension of the cross section is adapted to fit the diameter of the support pins 4.

[0025] In the exemplary embodiment of the present disclosure where the cross section of the cavity 3 perpendicular to the radial direction is rectangular or quadratic the first 5 and the second 6 support elements can be interval sections of the quadratic cavity 3.

[0026] According to another aspect of the present disclosure the first 5 and the second 6 support elements are bar elements perpendicular to a radial direction of the cavity 3. The first 5 and the second 6 support elements can be bar elements perpendicular to a radial direction of the cavity 3 in exemplary embodiments were the cavity 3 has different shape.

[0027] The cavity 3 does not have to be a closed space. An advantage with the cavity 3 not being a closed space is that the weight of the support ring 1 can be reduced.

[0028] In one exemplary embodiment were the first 5 and the second 6 support elements are bar elements 5, 6, the cross section of the cavity is rectangular or quadratic. In another exemplary embodiment were the first 5 and the second 6 support elements are the bar elements 5, 6 the cross section of the cavity is cylinder shaped.

[0029] The at least one entry element 7 may be embodied in many different ways. According to one aspect of the present disclosure the at least one entry element 7 is an outer edge of the cavity 3. An advantage with this embodiment is that it is not necessary to bend the support pin as much before the outer edge 7 can counteract the force, since the outer edge 7 is positioned further away from the centre of the support ring than the other edge of the cavity. The outer edge of the cavity can be embodied in many different ways. It is however important that the outer edge can counteract a force required bending the support pin to an angle where the support pin can be inserted into the cavity 3.

[0030] According to another aspect of the present disclosure the at least one entry element 7 is an element arranged at the radial outer opening of the cavity 3. This element can be embodied in many different ways. It is however important that the element can counteract a force required bending the support pin to an angle where the support pin can be inserted into the cavity 3.

[0031] The present disclosure also relates to a method for manufacturing a support ring 1 for mounting of a soft box on a light source. The method comprises a first step of providing the support ring 1 with attachment means 2 for attachment of the light source on the support ring 1. In a next step the support ring 1 is provided with at least one cavity 3 configured to receive support pins 4 of the soft box. Thereafter in yet another step the cavity 3 is provided with a first 5 and a second 6 support element arranged to counteract a torque from the support pins, when the support pins are in an inserted position in the cavity 3. Next, the cavity 3 is provided with at least one entry element 7 arranged on a radial outside of the cavity 3 and arranged to counteract a force required to bend the support pin to an angle where the support pin can be inserted into the cavity 3.

[0032] According to one aspect of the present disclosure the method of manufacturing the speed ring 1 comprises manufacturing the speed ring wherein the cavity 3 is cylinder shaped and wherein the diameter of the cylinder is adapted to the diameter of the support pins 4.

[0033] The speed ring can be manufactured so that the first 5 and the second 6 support elements are inner wall sections of the cylinder.

[0034] According to another aspect of the manufacturing method a cross section of the cavity 3 perpendicular to the radial direction is rectangular or quadratic and the dimension of the radial intersection is adapted to fit the diameter of the support pins 4.

[0035] Further in the method of manufacturing the speed ring, the first 5 and the second 6 support elements are inner wall sections of the rectangular or quadratic cavity 3. In another exemplary embodiment the first 5 and the second 6 support elements are bar elements perpendicular to a radial direction of the cavity 3.

[0036] According to one aspect of the manufacturing method the at least one entry element 7 is an outer edge of the cavity 3. In another embodiment of the method the at least one entry element 7 is an element arranged at the radial outer opening of the cavity 3.

[0037] In some implementations and according to some aspects of the disclosure of the method for manufacturing, the steps can occur in another order than the order described. For example, two method steps shown in succession can in fact be executed substantially concurrently or the method steps can sometimes be executed in the reverse order, depending upon the manufacturing method. Especially if the speed ring 1 is made of cast aluminium, the method steps are executed substantially concurrently.

[0038] In the drawings and specification, there have been disclosed exemplary aspects of the disclosure. However, many variations and modifications can be made to these aspects without substantially departing from the principles of the present disclosure. Thus, the disclosure should be regarded as illustrative rather than restrictive, and not as being limited to the particular aspects discussed above. Accordingly, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation.
