Description

Technical Field

[0001] This invention relates to accessories for photographic equipment, and in particular to a foldable, trumpet-shaped, small softbox. Background Technology

[0002] Photography often requires electric light sources to enhance the brightness of the subject and achieve good photographic results. However, the light emitted by electric light sources is often harsh and lacks softness, resulting in poor photographic effects from direct illumination. Therefore, a softbox is often attached to the electric light source to soften the light and improve its quality, thus enhancing the photographic outcome. A small, trumpet-shaped softbox is characterized by a large front diameter and a small rear diameter, with the electric light source positioned at the rear center. The light from the electric light source shines forward, softening the light and directly illuminating the subject, such as portraits or still life. Because trumpet-shaped softboxes are generally quite large when unfolded, they are often designed to be foldable or collapsible for easy portability.

[0003] Chinese Patent Publication No. CN215297908U discloses an inflatable softbox, a foldable, small, horn-shaped softbox. Its structural features include: a softbox fabric, a reflective fabric, and a box frame. The box frame forms a hollow cavity, the softbox fabric is disposed within the hollow cavity, and the reflective fabric is disposed on the inner wall of the hollow cavity so that light is reflected by the reflective fabric and then projected onto the softbox fabric. The box frame is an inflatable membrane structure, including an inflation port to maintain its expanded shape after inflation and to retract after deflation. The drawbacks of this design are: firstly, the box frame inflated by the membrane has poor rigidity, making it prone to deformation and shaking during use, affecting the stability of photographic lighting; secondly, relying solely on a single layer of softbox fabric for light softening results in an unsatisfactory softening effect.

[0004] Chinese Patent Publication No. CN218181297U discloses a foldable softbox, which is a foldable trumpet-shaped softbox. The structure includes a mounting base, characterized by a quick-folding device inside the mounting base. This quick-folding device includes: a frame, the ends of which are rotatably connected to the interior of the mounting base, with a reflective cloth fixedly connected to the surface of the frame, and a meshing gear fixedly connected to one end of the frame; a rack, the surface of which is slidably connected to the interior of the mounting base, and a rotating gear meshing on the surface of the rack; and a gear disc, the rear end of which is rotatably connected to the interior of the mounting base. The drawbacks of this design are: firstly, it uses a folding structure similar to an umbrella, resulting in a relatively large volume when folded, numerous components, a complex structure, and considerable weight, making it inconvenient to carry and expensive; secondly, it relies solely on a single layer of diffuser cloth at the front to soften the light, resulting in an unsatisfactory softening effect.

[0005] Chinese Patent Publication No. CN214414716U discloses a foldable basin, providing a reference solution for different fields where the container wall can be folded. The structure includes a basin opening and a basin bottom. The key feature is that an elastically deformable telescopic component connects the basin opening and the basin bottom. When an external force is applied to the basin bottom and it moves away from the basin opening, the telescopic component is stretched, causing the basin opening, the telescopic component, and the basin bottom to close together to form a basin-shaped structure. When an external force is applied to the basin bottom and it moves towards the basin opening, the telescopic component is compressed, causing the basin bottom to enter the basin opening. The telescopic component includes a first telescopic ring and a second telescopic ring made of elastic material, with a support ring made of rigid material connected between the first and second telescopic rings. The first telescopic ring connects to the basin opening, and the second telescopic ring connects to the basin bottom. The drawback of this solution is that... Figure 3 As shown, the walls of its first telescopic ring, second telescopic ring, and support ring are almost vertical, and the support ring is a wall ring made of highly rigid PP material. Figure 3 The unfolded state needs to be changed to its Figure 5 When folded, the first and second telescopic rings can only be flipped over due to their very soft texture, which allows them to be deformed at will. Because of the presence of these very soft wall rings, they are not suitable as a reference for the foldable wall of a softbox. During use, the entire softbox is prone to deformation and shaking, which will seriously affect the stability of photographic lighting. Summary of the Invention

[0006] In order to overcome the problems of poor overall rigidity, easy deformation and shaking during use, or large size, many components, complex structure, heavy weight, inconvenience to carry and high price of existing technologies, the purpose of this invention is to provide an improved foldable horn-shaped small softbox that can overcome the defects of existing technologies.

[0007] The technical solution adopted by this invention to solve its technical problem is: a foldable horn-shaped softbox, comprising a horn, a reflective cloth tube, a diffuser, and a mounting bracket; the reflective cloth tube is installed inside the horn, the diffuser is installed on the front port of the horn, and the mounting bracket is installed on the rear port of the horn, the mounting bracket being used to install an electric light source; characterized in that: the foldable horn-shaped softbox further includes a concave lens and a honeycomb light-blocking plate; the horn is composed of multiple cylindrical sections with increasing diameter connected together, wherein adjacent cylindrical sections are connected by a frustum, and the bevel angle of each frustum is 10°. ~40°, the connection between the cylinder and the frustum cylinder is a flexible connection; when the horn cylinder is folded into the cylinder where the front port is located along the axial direction, the cylinder walls of all the frustum cylinders are flipped back and forth along the axial direction of the horn cylinder; the rear opening of the concave lens and the reflective cloth tube is fixed to the rear port of the horn cylinder through the front part of the bracket, and the rear part of the bracket is used to install an electric light source; a large metal retaining ring is provided on the front opening of the reflective cloth tube, and the large metal retaining ring is locked inside the cylinder where the front port of the horn cylinder is located; the honeycomb light-blocking plate and the diffuser are installed in front and behind the inner side of the cylinder where the front port of the horn cylinder is located.

[0008] The inclined angle of the frustum cylinder described in the above technical solution refers to the angle between the generatrix of the frustum cylinder and the bottom surface of the frustum cylinder. The cylinder wall of the frustum cylinder takes the inclined angle of the frustum cylinder as 0° as the critical point for its forward and backward flipping.

[0009] In the above technical solution, the length of the frustum generatrix of one of the frustum cylinders can be greater than the height of another cylinder other than the cylinder where the front port is located, so that the trumpet cylinder can be folded into the cylinder where the front port is located along the axial direction.

[0010] The horn tube described in the above technical solution can be injection molded using plastic materials. Specifically, both the cylindrical tube and the frustum tube can be made of materials with sufficient rigidity and a certain degree of elasticity, such as polyethylene (PE) or polyvinyl chloride (PVC). Then, through a secondary injection molding process, thermoplastic elastomer (TPE) is used to cover all the cylindrical tubes and frustum tubes and form the entire horn tube. The thermoplastic elastomer (TPE) forms the flexible connection at the break between the cylindrical tube and the frustum tube, so that the flexible connection has good flexibility. The flexible connection can be made into a concave and thinned part on the horn tube, or the concave and thinned part can be made into a corrugated and tortuous shape.

[0011] The horn tube described in the above technical solution can be injection molded using plastic material. Specifically, the entire horn tube can be injection molded using silicone with a Shore hardness of 15 to 30A. The cylindrical and frustum sections adopt a thick-walled structure to achieve sufficient rigidity, while the flexible connection section adopts a thin-walled structure to achieve good flexibility. The flexible connection section with the thin-walled structure can be made into a corrugated and tortuous shape.

[0012] The cylinder at the front port of the horn tube described in the above technical solution can be divided into two parts, front and rear. The front part has a radially protruding front edge on the inner side of its front end. The honeycomb light-blocking plate, the diffuser, and the large metal retaining ring on the reflective cloth tube are all secured to the inner side of the front edge of the front part. The rear part is used to accommodate the folded cylinders other than the cylinder at the front port of the horn tube and all the frustum cylinders.

[0013] The aforementioned technical solution describes a radially protruding rear edge on the inner side of the rear end of the cylinder where the rear port of the horn tube is located, and a radially protruding cloth tube opening edge on the inner side of the rear opening of the reflective cloth tube. The front part of the mounting base is provided with a forward-extending mounting rod. The mounting rod passes through a rod hole one on the rear opening edge of the horn tube, then through a rod hole two on the cloth tube opening edge of the reflective cloth tube, and then passes into the mounting hole on the concave lens. A screw with a washer is threaded into the screw hole at the front end of the mounting rod, thereby fixing the front part of the mounting base, the rear opening of the reflective cloth tube, and the concave lens to the rear opening edge of the horn tube.

[0014] The reflective cloth tube described in the above technical solution may be provided with a small metal retaining ring in the middle. The small metal retaining ring is connected to the back side of the middle part of the reflective cloth tube and abuts against the inner step of the middle part of the horn tube, which is composed of the cylinder and the frustum, so as to prevent the middle of the reflective cloth tube from being concave inward when the reflective cloth tube is unfolded.

[0015] The concave lens described in the above technical solution can disperse the light emitted by the electric light source onto the reflective cloth tube through its concave mirror surface, and then reflect it onto the diffuser to improve the softening effect of the light from the electric light source.

[0016] The honeycomb light-blocking plate described in the above technical solution can be secured to the inner side of the front opening edge of the front part by means of the plate bracket on its outer side.

[0017] The beneficial effects of this invention are as follows: First, the horn tube is composed of multiple cylindrical sections with increasing diameters connected together. Adjacent cylindrical sections are connected by a frustum, with the angle of the frustum being 10-40°. The connection between the cylindrical sections is a flexible connection. When the horn tube folds along its axis into the cylinder containing the front port, the angle of the walls of all the frustums decreases from 10-40° to 0°, thus achieving a front-to-back flip. This requires only a small amount of elastic deformation between the frustum and the connected cylinder, without requiring the connected cylinder to have a very soft texture capable of arbitrary deformation. Therefore, all cylindrical sections and frustums can be formed from high-rigidity materials, ensuring good overall rigidity when the horn tube, capable of axial folding, is unfolded. This ensures that the foldable horn tube softbox will not deform or shake during use, achieving good stability for photographic lighting. Secondly, because the foldable horn-shaped softbox also includes a concave lens, the light emitted by the electric light source can be more dispersed and projected onto the reflective cloth tube, and then reflected by the reflective cloth tube onto the diffuser, effectively improving the softening effect of the electric light source. Thirdly, the foldable horn-shaped softbox also includes a honeycomb light-blocking plate, which can block the off-axis portion of the light emitted from the diffuser, allowing only the axial portion to pass through, thereby effectively improving the quality of photographic lighting. Fourthly, because the concave lens and the rear opening of the reflective cloth tube are fixed to the rear port of the horn tube through the front part of the mounting bracket, and the front opening of the reflective cloth tube is provided with a large metal retaining ring, which is locked inside the cylinder where the front port of the horn tube is located, the reflective cloth tube inside the horn tube can automatically unfold synchronously when the horn tube is unfolded. This is a clever, simple, sturdy, and practical structure for setting the reflective cloth tube inside the horn tube. Fifth, the speaker tube softbox of the present invention has the advantages of small folding volume, few components, simple structure, light weight, easy to carry, and low price.

[0025] Reference Figures 1-5 This foldable horn-shaped softbox includes a horn tube 1, a reflective cloth tube 2, a diffuser 3, and a mounting bracket 4. The reflective cloth tube 2 is installed inside the horn tube 1, the diffuser 3 is installed on the front port 5 of the horn tube 1, and the mounting bracket 4 is installed on the rear port 6 of the horn tube 1. The mounting bracket 4 is used to install an electric light source. Its characteristic is that the foldable horn-shaped softbox also includes a concave lens 7 and a honeycomb light-blocking plate 8. The horn tube 1 is composed of multiple cylindrical tubes 9 of increasing diameter connected together, wherein adjacent cylindrical tubes 9 are connected by a frustum 10. The slope angle α of the frustum 10 is 10–40°. The connection between 0 is a flexible connection 11; when the horn tube 1 is folded into the cylinder 12 where the front port is located along the axial direction, the cylinder walls of all the frustum cylinders 10 are flipped back and forth along the axial direction of the horn tube; the concave lens 7 and the rear cylinder opening 13 of the reflective cloth tube 2 are fixed to the rear port 6 of the horn tube 1 through the front part of the bracket 4, and the rear part 14 of the bracket 4 is used to install an electric light source; a large metal retaining ring 15 is provided on the front cylinder opening of the reflective cloth tube 2, and the large metal retaining ring 15 is locked inside the cylinder 12 where the front port of the horn tube 1 is located; the honeycomb light blocking plate 8 and the diffuser 3 are installed in front and back order inside the cylinder 12 where the front port of the horn tube 1 is located.

[0026] In addition, such as Figure 5 As shown, the inclined plane angle α of the frustum cylinder 10 refers to the angle between the generatrix 16 of the frustum cylinder 10 and the bottom surface 17 of the frustum. The wall of the frustum cylinder 10 is at the critical point of its forward and backward flipping when the inclined plane angle α of the frustum cylinder 10 is 0°.

[0027] like Figure 4 As shown, the length of the frustum generatrix 16 of one of the frustum cylinders 10 is greater than the length of the height 18 of another cylinder 9 other than the cylinder 12 where the front port is located, so that the horn cylinder 1 can be folded into the cylinder 12 where the front port is located along the axial direction.

[0028] The horn tube 1 is injection molded from plastic material. Specifically, both the cylinder 9 and the frustum cylinder 10 can be made of materials with sufficient rigidity and a certain degree of elasticity, such as polyethylene (PE) or polyvinyl chloride (PVC). Then, through a secondary injection molding process, thermoplastic elastomer (TPE) is used to cover all the cylinders 9 and frustum cylinders 10 and form the whole of the horn tube 1. The thermoplastic elastomer (TPE) is used to form the flexible connection 11 at the break between the cylinder 9 and the frustum cylinder 11, so that the flexible connection 11 has good flexibility. The flexible connection 11 is made into the concave and thinned part on the horn tube.

[0029] The horn tube 1 is injection molded from plastic material. Specifically, the entire horn tube 1 can be injection molded from silicone with a Shore hardness of 15 to 30A. The cylindrical tube 9 and the frustum tube 10 are thick-walled to achieve sufficient rigidity, while the flexible connection 11 is thin-walled to achieve good flexibility.

[0030] The cylinder 12 at the front port of the horn tube 1 is divided into front and rear parts. The front part 19 has a radially protruding front edge 20 on its inner side. The honeycomb light-blocking plate 8, the diffuser 3, and the large metal retaining ring 15 on the reflective cloth tube 2 are all secured to the inner side of the front edge 20 of the front part 19. The rear part 21 is used to accommodate the folded other cylinders 9 except for the cylinder 12 at the front port of the horn tube 1 and all the frustum cylinders 10.

[0031] The rear end of the cylinder containing the rear port 6 of the horn tube 1 is provided with a radially protruding rear edge 22. The rear opening 13 of the reflective cloth tube 2 is provided with a radially protruding cloth opening 23. The front part of the mounting base 4 is provided with a forward-extending mounting rod 24. The mounting rod 24 passes through the rod hole 25 on the rear opening 22 of the horn tube 1, then through the rod hole 26 on the cloth opening 23, and then passes into the mounting hole 27 on the concave lens 7. The front part of the mounting base 4, the rear opening 13 of the reflective cloth tube 2, and the concave lens 7 are fixed to the rear opening 22 of the horn tube 1 by means of a screw 28 with a washer threadedly engaged in the screw hole at the front end of the mounting rod 24.

[0032] The reflective cloth tube 2 is provided with a small metal retaining ring 29 in the middle. The small metal retaining ring 29 is connected to the back of the middle part of the reflective cloth tube 2 and abuts against the inner step of the middle part of the speaker tube 1, which is composed of the cylinder 9 and the frustum cylinder 10, so that the middle of the reflective cloth tube 2 is not concave when it is unfolded.

[0033] The concave lens 7, through its concave mirror surface 30, allows the light emitted by the electric light source to be more dispersed and projected onto the reflective cloth tube 2, and then reflected by the reflective cloth tube 2 onto the diffuser 3, thereby improving the softening effect on the light from the electric light source.

[0034] The honeycomb light-blocking plate 8 is secured to the inside of the front edge 20 of the cylinder 12 where the front port of the speaker tube 1 is located via the plate bracket 31 on its outer side.

[0035] When using, such as Figure 1 , Figure 3 and Figure 5 As shown, when the foldable horn-shaped softbox is unfolded, the large metal retaining ring 15 is engaged inside the cylinder 12 where the front port of the horn 1 is located. The front part of the retaining base 4, the rear cylinder opening 13 of the reflective cloth tube 2, and the concave lens 7 are fixed to the rear edge 22 of the horn 1. The small metal retaining ring 29 is connected to the back of the middle part of the reflective cloth tube 2 and presses against the inner step formed by the cylinder 9 and the frustum cylinder 10 in the middle of the horn 1. Therefore, the reflective cloth tube 2 can unfold automatically and synchronously inside the horn 1. At this time, the light emitted by the electric light source installed on the rear part 14 of the retaining base 4 is dispersed and projected onto the reflective cloth tube 2 through the concave lens 30 on the concave lens 7. The light is then reflected by the reflective cloth tube 2 onto the softbox 3, and then blocked by the honeycomb light-blocking plate 8 to block the off-axis irradiation part of the light. The softened light illuminating the axis shines forward to provide lighting for photography. When the photography lighting is complete, the foldable trumpet-shaped softbox is folded up. By pressing the front port 5 and / or rear port 6 of the trumpet 1 axially, all the frustum cylinders 10 undergo a slight elastic deformation due to their own and the cylinders 9, causing them to flip back and forth. That is, the slope angle α of the frustum cylinders 10 gradually decreases from 10 to 40°, and after crossing the slope angle 0°, they flip back and forth. Thus, the front flexible connection part of the frustum cylinder 10 becomes the rear, and the rear flexible connection part becomes the front. At this time, all the cylinders 9 except the cylinder 12 where the front port is located, and all the frustum cylinders 10, are folded into the rear part 21 of the cylinder 12 where the front port is located. The reflective cloth tube 2 also automatically folds back inside the trumpet 1, thus becoming... Figure 4 The folded state shown.
