## Abstract

A pneumatic frame for textiles of control at of light used in the film industry or images capture with the object to reflect, block, filter, blur and make any use of light and have optimum control of it at the time of capturing the image. The pneumatic frame comprises a hose inflatable structure of at least twelve pieces with threads that allow its assembly, tucks vulcanized along its entire periphery which allow the passage of an elastic which is intertwined with the stitched slit, secured by hang setbolt devices along its entire periphery, as well as external gripping devices of type-setbolt screw pins.

## Claims

### Claim 1

A pneumatic frame for textiles of control and/or modification of light, comprising:
a structure of inflatable pneumatic hose, wherein the inflatable pneumatic hose includes at least twelve pieces;
at least four filing and deflating check valves, each one vulcanized in an elbow of a corner of a periphery of the pneumatic frame;
at least sixteen gripping handles for manual manipulation of the pneumatic frame, four handles in each side of the periphery of the frame;
at least four metal rings for external gripping or clamping of the frame, each ring vulcanized on a corner of the frame;
at least four external connection devices of the frame, wherein the external connection devices of the frame are gripping pins with a setbolt screw, and wherein the gripping pins with setbolt screws allow the gripping pins to receive a T-shape external connection plate, entering through the gripping pins' holes and sliding down by the gripping pins' canal to remain under pressure;
at least fifty-nine tucks vulcanized along the periphery of the pneumatic frame;
an elastic;
at least eight hang type-setbolt devices;
a textile with stitched slot along its entire periphery to hold the same in any medium, depending of its use, wherein the elastic joins to the textile; and
a hang type-setbolt devices throughout the periphery of the pneumatic frame in the back of the pneumatic frame.

### Claim 2 (depends on 1)

A pneumatic frame according to claim 1, wherein the structure of inflatable pneumatic hose comprises:
at least four elbows set each in each corner of the structure with screw termination for connection of the hose to other parts of the internal structure;
at least two pieces of PVC inflatable pneumatic hose of 20 feet long each, with screw termination for connection of the hose to other parts of the internal structure;
at least four pieces of PVC inflatable pneumatic hose of 8 feet long each, with screw termination for connection of the hose to other parts of the internal structure; and
at least two pieces of PVC inflatable pneumatic hose of 4 feet long each (15), with screw termination for connection of the hose to other parts of the internal structure.

### Claim 3 (depends on 2)

A pneumatic frame according to claim 2, wherein each elbow of the inflatable pneumatic hose structure contains an air filling and deflation check valve.

### Claim 4 (depends on 1)

A pneumatic frame according to claim 1, wherein the structure of the inflatable pneumatic hose comprises PVC inflatable pneumatic hose.

### Claim 5 (depends on 1)

A pneumatic frame according to claim 1, wherein the structure of the inflatable pneumatic hose is assembled by means of threads that fit together and connect together forming a frame.

### Claim 6 (depends on 1)

A pneumatic frame according to claim 1, wherein the structure of the inflatable pneumatic hose increases the pneumatic frame's resistance to hard use, allowing the exchange of each piece separately in case of damage without compromising the integrity of the pneumatic frame in its entirety.

### Claim 7 (depends on 1)

A pneumatic frame according to claim 1, wherein the gripping pins with setbolt screws are set parallel in each side of the pneumatic frame for the holding thereof to any external device which allows the mounting of the frame.

### Claim 8 (depends on 1)

A pneumatic frame according to claim 1, wherein the tucks vulcanized along the periphery of the pneumatic frame form a channel which allows the passage of the elastic to hold the textile.

### Claim 9 (depends on 1)

A pneumatic frame according to claim 1, wherein the textile is attached to the frame by the elastic which is intertwined among the tucks and stitched slit.

### Claim 10 (depends on 1)

A pneumatic frame according to claim 1, wherein the hang type-setbolt devices in every corner of the pneumatic frame allow the elastic to stop, exerting the necessary pressure to hold the textile.

### Claim 11 (depends on 1)

A pneumatic frame according to claim 1, wherein the hang type-setbolt devices throughout the periphery of the frame in its back stop the outgoing elastic between each tuck of the frame and every stitched slit, exerting the necessary pressure to hold the textile.

### Claim 12 (depends on 1)

A pneumatic frame according to claim 1, wherein the pneumatic frame is used in the film industry or of digital or analogue capture of images or photographs, in order to reflect, block, filter, blur and make any use of light and have optimum control of it at the time of capturing the image.

### Claim 13 (depends on 1)

A pneumatic frame according to claim 1, wherein the textile includes any textile which has stitched slit.

### Claim 14

A pneumatic frame for textiles of control and/or modification of light, comprising:
a structure of inflatable pneumatic hose, wherein the inflatable pneumatic hose includes at least twelve pieces;
at least four filing and deflating check valves, each one vulcanized in an elbow of a corner of a periphery of the pneumatic frame;
at least sixteen gripping handles for manual manipulation of the pneumatic frame, four handles in each side of the periphery of the frame;
at least four metal rings for external gripping or clamping of the frame, each ring vulcanized on a corner of the frame;
at least four external connection devices of the frame;
at least fifty-nine tucks vulcanized along the periphery of the pneumatic frame;
an elastic;
at least eight hang type-setbolt devices;
a textile with stitched slot along its entire periphery to hold the same in any medium, depending of its use, wherein the elastic joins to the textile; and
a hang type-setbolt devices throughout the periphery of the pneumatic frame in the back of the pneumatic frame;
wherein the periphery of the pneumatic frame already assembled is of 2 inches wide or less, which allows the reduction of shadow which sometimes reflects in the modification and filtering applications of light.

### Claim 15 (depends on 14)

A pneumatic frame according to claim 14, wherein the tucks vulcanized along the periphery of the pneumatic frame form a channel which allows the passage of the elastic to hold the textile.

### Claim 16 (depends on 14)

A pneumatic frame according to claim 14, wherein the textile is attached to the frame by the elastic which is intertwined among the tucks and stitched slit.

### Claim 17 (depends on 14)

A pneumatic frame according to claim 14, wherein the hang type-setbolt devices in every corner of the pneumatic frame allow the elastic to stop, exerting the necessary pressure to hold the textile.

### Claim 18 (depends on 14)

A pneumatic frame according to claim 14, wherein the hang type-setbolt devices throughout the periphery of the frame in its back stop the outgoing elastic between each tuck of the frame and every stitched slit, exerting the necessary pressure to hold the textile.
