Clothes air conditioning device

Abstract

To provide an air blower for air-conditioned clothing, which can solve the conventional problems that the fabric of clothing is wrinkled, making it look bad, damaging the fabric of clothing, and making it difficult to remove. [Solution] Even when the external cylinder 5 is rotated, the inner surface of the female thread-forming cylindrical portion 14 of the external cylinder 5 is formed further outward than the inner surface of the female thread-forming cylindrical portion 14 of the external cylinder 5 that is radially outward, so that the external cylinder 5 comes into contact with the fabric of the garment 2 at the inner surface that is radially outward of the female thread-forming cylindrical portion 14 of the external cylinder 5. As a result, even when the external cylinder 5 is rotated, the tightening force of the screw is less likely to be transmitted to the contact surface of the fabric of the garment 2.

Description

[Technical Field]

[0001] The present invention relates to a clothing air conditioning blower that is attached to an opening in the fabric of clothing and blows outside air from the outside to the inside of the clothing to suppress sweating of the wearer. [Background technology]

[0002] A garment air conditioning and blowing device that is attached to an opening in the fabric of clothing and blows outside air from the outside to the inside of the clothing to suppress sweating of the wearer has been known. One such garment air conditioning and blowing device (air-conditioned garment blowing device 110) includes an inner cylindrical portion 111 that houses a motor M and a fan 118 rotated by the motor M, an outer cylindrical portion 140 that is attached to the outside of the inner cylindrical portion 111 and has an intake hole 149 for introducing outside air and a flange 142 that protrudes radially from its outer peripheral surface, and an annular ring 150 that is threadedly connected to the outer peripheral surface of the inner cylindrical portion 111, and the threaded connection between the inner cylindrical portion 111 and the ring 150 is formed by a multiple-start thread 113, 153 having two or more start holes (see, for example, Patent Document 1).

[0003] Then, the inner cylindrical portion 111 and the outer cylindrical portion 140 are connected to each other along the axial direction, including the locking means (not shown), and then most of the inner cylindrical portion 111 and the outer cylindrical portion 140 are inserted into the mounting hole 109 of the air-conditioning garment 100 from outside the garment, and the flange 142 of the outer cylindrical portion 140 is brought into close contact with the outer periphery of the mounting hole 109. Then, the ring body 150 is brought close to the cylindrical peripheral portion 112 of the inner cylindrical portion 111 connected to the outer cylindrical portion 140 from the inside of the air-conditioning garment 100, and the double thread 153 of the ring body 150 and the double thread 113 of the inner cylindrical portion 111 are screwed together, and the inner peripheral edge of the mounting hole 109 of the air-conditioning garment 100 is clamped from both the inside and outside by the flange 142 of the outer cylindrical portion 140 connected to the inner cylindrical portion 111 and the annular piece 151 of the ring body 150. Furthermore, as the screwing operation is performed, the multiple uneven strips 156 formed on the annular piece 151 of the ring body 150 rotate and bite into the fabric located inside the mounting hole 109, so that the air-conditioning clothing blower 110, which is composed of the inner cylindrical portion 11, the outer cylindrical portion 40, and the ring body 50, can be firmly attached to the air-conditioning clothing 100 in a state where it blocks the mounting hole 109 of the air-conditioning clothing 100.

[0004] [Patent Document 1] Utility Model Registration No. 3217531 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the conventional air-conditioned garment blower 110, when the fabric of the air-conditioned garment 100 is sandwiched between the flange 142 of the outer cylindrical portion 140 connected to the inner cylindrical portion 111 and the annular piece 151 of the ring body 150, rotating the ring body 150 causes the multiple ridges 156 formed on the annular piece 151 of the ring body 150 to dig into the fabric inside the mounting hole 109, pulling the fabric of the air-conditioned garment 100, causing wrinkles in the fabric of the air-conditioned garment 100, resulting in a poor appearance, damaging the fabric of the air-conditioned garment 100, and making it difficult to remove the air-conditioned garment blower. This problem occurs not only when using a ring body 150 with multiple ridges 156 formed thereon, as in the conventional air-conditioned garment blower 110, but also when using one without multiple ridges 156 formed thereon.

[0006] To provide a clothing air-conditioning and blowing device that can prevent wrinkles from forming in the fabric of clothing when the clothing air-conditioning and blowing device is attached, does not spoil the appearance, does not damage the fabric of the clothing, and does not make it difficult to remove the air-conditioning and blowing device for clothing. [Means for solving the problem]

[0007] In order to solve the above problems and achieve the above objects, a first aspect of the present invention is a garment air conditioning blower that is attached to an opening in the fabric of a garment and blows outside air from the outside to the inside of the garment to suppress sweating of the wearer, and is characterized by having: a fan that rotates by the driving force of a motor; an inner cylindrical body that houses the fan and has an air supply hole on its inner surface and a flange portion that protrudes radially on its outer peripheral surface, and has a male thread threaded on the outer peripheral surface of the flange outer cylindrical portion outside the flange portion; and an outer cylindrical body that has an air intake hole on its outer surface for introducing outside air and has a female thread threaded on its inner peripheral surface that screws together with the male thread threaded on the outer peripheral surface of the flange outer cylindrical portion of the inner cylindrical body, and the inner surface of the cylindrical female thread-formed cylindrical portion of the outer cylindrical body is formed in a more outward direction than the inner surface of the female thread-formed cylindrical portion of the outer cylindrical body in the radially outward direction.

[0008] According to the present invention, the inner surface of the female-threaded cylindrical portion of the outer cylinder, which is cylindrical and has a female thread, is formed further outward than the radially outward inner surface of the female-threaded cylindrical portion of the outer cylinder. Therefore, the clothing fabric of the outer cylinder comes into contact with the radially outward inner surface of the female-threaded cylindrical portion of the outer cylinder. Therefore, even when the outer cylinder is rotated with the clothing fabric sandwiched between the outer surface of the flange of the inner cylinder and the radially outward inner surface of the female-threaded cylindrical portion of the outer cylinder, the tightening force of the screws is not easily transmitted to the contact surface of the clothing fabric. This prevents wrinkling of the clothing fabric, avoids poor appearance, and does not damage the clothing fabric. Furthermore, the air-conditioned clothing blower can be easily removed.

[0009] The second aspect of the present invention is a clothing air conditioning fan according to the first aspect, characterized in that the radial width of the inner surface of the female thread-forming cylindrical portion of the outer cylinder is longer than the radial width of the inner surface of the outer cylinder radially outward from the female thread-forming cylindrical portion.

[0010] According to the present invention, the radial width of the inner surface of the female thread-forming cylindrical portion of the outer cylinder is longer than the radial width of the inner surface of the outer cylinder radially outward from the female thread-forming cylindrical portion. In other words, the radial width of the inner surface of the outer cylinder radially outward from the female thread-forming cylindrical portion is shorter than the radial width of the inner surface of the female thread-forming cylindrical portion of the outer cylinder. This reduces the radial width of the inner circumferential surface of the outer cylinder that comes into contact with the clothing fabric. Therefore, even when the outer cylinder is rotated with the clothing fabric sandwiched between the outer surface of the flange of the inner cylinder and the radially outward inner surface of the female thread-forming cylindrical portion of the outer cylinder, the tightening force of the screws is less likely to be transmitted to the contact surface of the clothing fabric. This effectively prevents wrinkling of the clothing fabric, maintaining its appearance and preventing damage to the clothing fabric, and facilitating removal of the air-conditioned clothing blower.

[0011] The third aspect of the present invention is a clothing air conditioning fan according to the first aspect, characterized in that a space is formed between the inner surface of the female thread-forming cylindrical portion of the outer cylinder and the inner surface of the outer cylinder radially outward from the female thread-forming cylindrical portion.

[0012] According to the present invention, a space is formed between the inner surface of the female thread-forming cylindrical portion of the outer cylinder and the inner surface radially outward of the female thread-forming cylindrical portion of the outer cylinder. Therefore, even when the outer cylinder is rotated with the clothing fabric sandwiched between the outer surface of the flange portion of the inner cylinder and the inner surface radially outward of the female thread-forming cylindrical portion of the outer cylinder in contact with the clothing fabric, the space between the inner surface of the female thread-forming cylindrical portion of the outer cylinder and the inner surface radially outward of the female thread-forming cylindrical portion of the outer cylinder allows the inner surface radially outward of the female thread-forming cylindrical portion to move flexibly left and right. This allows the inner surface radially outward of the female thread-forming cylindrical portion to move flexibly left and right, thereby preventing wrinkling of the clothing fabric, improving appearance, preventing damage to the clothing fabric, and facilitating removal of the air-conditioned clothing blower.

[0013] The fourth aspect of the present invention is a clothing air conditioning fan according to the first aspect, characterized in that the fan is arranged in approximately the same plane as the outer surface of the flange portion of the inner cylindrical body when attached to the fabric of the clothing.

[0014] According to the present invention, when the fan is attached to the fabric of the clothing, it is positioned approximately flush with the outer surface of the flange portion of the inner cylinder. Therefore, when the inner cylinder is attached to the clothing, it does not protrude significantly into the clothing, which allows for a larger space inside the clothing, allowing for a wider flow of air (wind) inside the clothing, providing sufficient comfort to the wearer of the clothing.

[0015] The fifth aspect of the present invention is a clothing air conditioning fan according to the first aspect, characterized in that it is attached to clothing with an ice pack inserted into an ice pack pocket on the inner surface of the fabric.

[0016] According to this invention, an ice pack is inserted into the ice pack pocket on the inner surface of the fabric and attached to the garment, so that the air blown from the garment air conditioning unit is cooled by the ice pack and sent into the garment, providing sufficient comfort to the wearer of the garment. [Effects of the Invention]

[0017] According to the clothing air conditioning and blowing device of the present invention, it is possible to prevent the formation of wrinkles in the clothing fabric when the clothing air conditioning and blowing device is attached, so that the appearance is not deteriorated, the clothing fabric is not damaged, and the air conditioning clothing blowing device is not difficult to remove.

[0019] An embodiment of the garment air conditioning and blower device of the present invention will be described below with reference to the drawings. Here, Fig. 1 shows a state in which the garment air conditioning and blower device of the present invention is attached to a garment, Fig. 2(a) is an outward perspective view of the garment air conditioning and blower device, Fig. 2(b) is an inward perspective view of the garment air conditioning and blower device, Fig. 3(a) is an inward perspective view of the inner cylinder of the garment air conditioning and blower device, Fig. 3(b) is an outward perspective view of the inner cylinder of the garment air conditioning and blower device, Fig. 4(a) is an outward perspective view of the outer cylinder of the garment air conditioning and blower device, and Fig. 4(b) is an inward perspective view of the outer cylinder of the garment air conditioning and blower device.

[0020] The garment air conditioning and blowing device 1 is attached to an opening 3 provided in the fabric of the garment 2, and blows outside air from the outside to the inside of the garment 2 to suppress sweating of the wearer, and has an inner tubular body 4 and an outer tubular body 5 (see FIGS. 1 to 4). Note that while this embodiment will be described using a garment 2 with long sleeves, this is not limiting, and short-sleeved or sleeveless garments 2 may also be used. Here, in this embodiment, the side of the garment 2 worn by the wearer that faces the body of the wearer is referred to as the inside, and the opposite side of the garment 2 is referred to as the outside.

[0021] The inner cylindrical body 4 has a fan 6 installed therein, an air supply hole 7 on its inner surface, a flange portion 8 that protrudes radially on its outer peripheral surface, and a male screw 10 threaded on the outer peripheral surface of a flange outer cylindrical portion 9 outside the flange portion 8 (see Figures 2 and 3).

[0022] The fan 6 is a device that rotates by the driving force of a motor (not shown), and as the fan 6 rotates, outside air from the outside of the garment 2 is sent into the inside of the garment 2 through the air supply holes 7. The air supply holes 7 have many holes formed therein for sending outside air from the outside of the garment 2 into the inside of the garment 2, and the air supply holes 7 have a substantially flat surface at the approximate center of the inner surface, and are formed to expand radially outward from the outer periphery of the substantially flat surface. A motor (not shown) that rotates the fan 6 is built into the approximate center of the substantially flat surface on the inner surface where the air supply holes 7 are provided, and the rotation shaft of the fan 6 is connected to the motor (not shown). The motor (not shown) is driven by a battery (not shown), which can be charged via a power terminal 11.

[0023] The flange portion 8 is provided on the outer peripheral surface on the outer side of the air supply hole 7, and is formed in a circular outer shape that protrudes in the radial direction with approximately the same thickness and same curvature. A male thread 10 is threaded on the outer peripheral surface of a flange outer cylindrical portion 9 on the outside of the flange portion 8.

[0024] The outer cylindrical body 5 has an intake hole 12 on its outer surface for introducing outside air, and an internal thread 13 threaded on its inner circumferential surface that engages with an external thread 10 threaded on the outer circumferential surface of the flanged outer cylindrical portion 9 of the inner cylindrical body 4. The intake holes 12 are formed with many holes for sending outside air from the outside of the garment 2 to the inside of the garment 2, and the outer surface on which the intake holes 12 are formed is formed in a curved shape that widens radially outward. Furthermore, an internal thread 13 is threaded on the inner circumferential surface of an internally threaded cylindrical portion 14 on the inward side of the intake holes 12 (see Figures 2 and 4).

[0025] The inner surface of the cylindrical female-thread-formed cylindrical portion 14 on which the female thread 13 of the external cylinder body 5 is formed is formed more outward than the radially outward inner surface of the female-thread-formed cylindrical portion 14 of the external cylinder body 5 (see FIGS. 5 and 6 ). Here, FIG. 5 is a rear view of the external cylinder body of a garment air conditioning blower device according to one embodiment of the present invention, and FIG. 6 is a cross-sectional view taken along the line AA of FIG. 5 . The “inner surface of the female-thread-formed cylindrical portion 14” refers to the surface of the female-thread-formed cylindrical portion 14 facing the body of the wearer of the garment 2. Furthermore, the phrase “formed more outward than the radially outward inner surface of the female-thread-formed cylindrical portion 14” means that the female-thread-formed cylindrical portion 14 is formed more outward from the garment 2 than the radially outward inner surface of the female-thread-formed cylindrical portion 14, i.e., shorter than the radially outward inner surface of the female-thread-formed cylindrical portion 14. Thus, the female-thread-formed cylindrical portion 14 is the cylindrical portion on which the female thread 13 is formed, and the inner surface of the external cylinder body 5 is formed shorter inward than the other inner portions of the external cylinder body 5. As a result, the inner surface of the cylindrical female thread forming cylindrical portion 14 on which the female thread of the outer cylinder body 5 is provided is formed further outward than the inner surface of the female thread forming cylindrical portion 14 of the outer cylinder body 5 in the radially outward direction, so that the outer cylinder body 5 comes into contact with the fabric of the clothing at the inner surface of the female thread forming cylindrical portion 14 of the outer cylinder body 5 in the radially outward direction.

[0026] As described above, the inner surface of the cylindrical female-thread-forming cylindrical portion 14 on which the female thread 13 of the external cylinder 5 is provided is formed outward from the inner surface of the female-thread-forming cylindrical portion 14 of the external cylinder 5 in the radially outward direction, so that the fabric of the garment 2 comes into contact with the radially outward inner surface of the female-thread-forming cylindrical portion 14 of the external cylinder 5. As a result, even if the external cylinder 14 is rotated with the fabric of the garment 2 sandwiched between the outer surface of the flange 8 of the internal cylinder 4 and the radially outward inner surface of the female-thread-forming cylindrical portion 14 of the external cylinder 5, the tightening force of the screws is unlikely to be transmitted to the contact surface of the fabric of the garment 2. This prevents wrinkling of the fabric of the garment 2, maintaining its appearance and preventing damage to the fabric of the garment 2, and also allows the air-conditioned clothing blower 1 to be easily removed.

[0027] Furthermore, the radial width of the inner surface of the female thread-forming cylindrical portion 14 of the external cylindrical body 5 is longer than the radial width of the inner surface of the external cylindrical body 5 radially outward from the female thread-forming cylindrical portion 14 (see FIG. 6 ). In other words, the radial width of the inner surface of the external cylindrical body 5 radially outward from the female thread-forming cylindrical portion 14 is shorter than the radial width of the inner surface of the external cylindrical body 5. Here, "the radial width of the inner surface of the female thread-forming cylindrical portion 14 of the external cylindrical body 5" refers to the radial (diameter) width of the inner surface of the female thread-forming cylindrical portion 14 of the external cylindrical body 5, and "the radial width is longer than the radial width of the inner surface of the external cylindrical body 5 radially outward from the female thread-forming cylindrical portion 14" means that the radial (diameter) width is longer than the radial width of the inner surface of the external cylindrical body 5 radially outward from the female thread-forming cylindrical portion 14. In this embodiment, the radial width of the inner surface of the female thread forming cylindrical portion 14 of the outer cylinder body 5 is longer than the radial width of the inner surface radially outward from the female thread forming cylindrical portion 14 of the outer cylinder body 5, but this is not limited to this, and the radial width of the inner surface of the female thread forming cylindrical portion 14 of the outer cylinder body 5 does not have to be longer than the radial width of the inner surface radially outward from the female thread forming cylindrical portion 14 of the outer cylinder body 5.

[0028] In this way, the radial width of the inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5 is longer than the radial width of the inner surface radially outward from the female thread-forming cylindrical portion 14 of the outer cylinder 5. In other words, the radial width of the inner surface radially outward from the female thread-forming cylindrical portion 14 of the outer cylinder 5 is shorter than the radial width of the inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5. As a result, the radial width of the inner circumferential surface of the outer cylinder 5 that comes into contact with the fabric of the clothing 2 becomes smaller. Therefore, even if the outer cylinder 5 is rotated with the fabric of the clothing 2 sandwiched between the outer surface of the flange portion 8 of the inner cylinder 4 and the radially outward inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5, the tightening force of the screw is less likely to be transmitted to the contact surface of the fabric of the clothing 2. This can further prevent the fabric of the clothes 2 from wrinkling, so that the clothes 2 do not look bad, the fabric of the clothes 2 is not damaged, and the air-conditioned clothing blower 1 can be easily removed.

[0029] Furthermore, a space is formed between the inner surface of female thread-forming cylindrical portion 14 of external cylinder body 5 and the inner surface of external cylinder body 5 that is radially outward from female thread-forming cylindrical portion 14 (see FIG. 6). Note that in this embodiment, a space is provided between the inner surface of female thread-forming cylindrical portion 14 of external cylinder body 5 and the inner surface of external cylinder body 5 that is radially outward from female thread-forming cylindrical portion 14 of external cylinder body 5, but this is not limiting, and it is not necessary to provide a space between the inner surface of female thread-forming cylindrical portion 14 of external cylinder body 5 and the inner surface of external cylinder body 5 that is radially outward from female thread-forming cylindrical portion 14 of external cylinder body 5.

[0030] In this way, a space is formed between the inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5 and the inner surface radially outward of the female thread-forming cylindrical portion 14 of the outer cylinder 5. Therefore, even if the fabric of the clothing 2 is sandwiched between the outer surface of the flange portion 8 of the inner cylinder 4 and the radially outward inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5 and the outer cylinder 5 is rotated while the fabric of the clothing 2 is in contact with the radially outward inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5, the space between the inner surface of the female thread-forming cylindrical portion 14 of the outer cylinder 5 and the inner surface radially outward of the female thread-forming cylindrical portion 14 of the outer cylinder 5 allows the radially outward inner surface of the female thread-forming cylindrical portion 14 to move flexibly left and right. In this way, the inner surface of the female thread forming cylindrical portion 14 in the radially outward direction can move flexibly left and right, which further prevents wrinkles from forming in the fabric of the clothing 2, does not spoil the appearance, does not damage the fabric of the clothing 2, and also makes it easy to remove the air-conditioned clothing blower 1.

[0031] Furthermore, when the fan 6 is attached to the fabric of the garment 2, it is disposed on approximately the same plane as the outer surface of the flange 8 of the inner cylindrical body 4 (see FIG. 7 ). Here, "the outer surface of the flange 8 of the inner cylindrical body 4" refers to the surface of the flange 8 of the inner cylindrical body 4 that comes into contact with the fabric of the garment 2, and "disposed on approximately the same plane as the outer surface of the flange 8 of the inner cylindrical body 4" means that the fan 6 is disposed on a plane formed by the outer surfaces of the flange 8 of the inner cylindrical body 4. Note that in this embodiment, the fan 6 is disposed on approximately the same plane as the outer surface of the flange 8 of the inner cylindrical body 4 when attached to the fabric of the garment 2, but this is not limiting, and the fan 6 does not have to be disposed on approximately the same plane as the outer surface of the flange 8 of the inner cylindrical body 4 when attached to the fabric of the garment 2. Here, FIG. 7 is a cross-sectional view taken along line B-B of FIG. 2.

[0032] In this way, when the fan 6 is attached to the fabric of the garment 2, it is arranged on approximately the same plane as the outer surface of the flange portion 8 of the inner cylindrical body 4. Therefore, when the inner cylindrical body 4 is attached to the garment 2, the inner cylindrical body 2 does not protrude significantly into the garment, and the space inside the garment 2 can be made larger, allowing the air (wind) to flow widely inside the garment 2 and providing sufficient comfort to the wearer of the garment 2.

[0033] The garment 2 is also provided with an ice pack pocket 16 on the inner surface of the fabric for inserting an ice pack 15 (see FIG. 8). The garment air conditioning and blowing device 1 is attached to the garment 2 with the ice pack 15 inserted in the ice pack pocket 16 on the inner surface of the fabric. Here, FIG. 8 is a diagram showing the location of the ice pack pocket on the inner surface of the fabric of the garment to which the garment air conditioning and blowing device is attached in one embodiment of the present invention.

[0034] In this way, the garment air conditioning and blowing device 1 is attached to the garment 2 with the ice pack 15 inserted in the ice pack pocket 16 on the inner surface of the fabric, and the air blown from the garment air conditioning and blowing device 1 is cooled by the ice and sent into the garment 2, thereby providing sufficient comfort to the wearer of the garment 2.

[0035] Next, a method for wearing the garment air conditioning and blower device 1 will be described.

[0036] First, in S1, an inner cylinder fabric insertion step is carried out. In this inner cylinder fabric insertion step, the flange outer cylindrical portion 9 of the inner cylinder 4 is inserted into the opening 3 of the fabric from the inside of the garment 2. This brings the fabric of the garment 2 into contact with the flange portion 8 of the inner cylinder 4. Then, the process proceeds to S2.

[0037] In S2, an external cylinder fastening step is performed. In this external cylinder fastening step, the female thread cylindrical portion 14 on the inner peripheral surface of the external cylinder 5 is brought close to the flange portion 8 of the internal cylinder 4 from outside the garment 2, and the external cylinder 5 is then rotated so that the female thread 13 of the female thread cylindrical portion 14 of the external cylinder 5 threadably engages with the male thread 10 of the flange outer cylindrical portion 9 on the outside of the flange portion 8 of the internal cylinder 4. This allows the external cylinder 5 to be attached and fixed to the internal cylinder 4 with the fabric of the garment 2 sandwiched between the outer surface of the flange 8 of the internal cylinder 4 and the radially outward inner surface of the female thread cylindrical portion 14 of the external cylinder 5. In this manner, the garment air conditioning blower 1 can be attached to the garment 2.

[0038] In this way, even if the outer cylinder 14 is rotated with the fabric of the garment 2 sandwiched between the outer surface of the flange 8 of the inner cylinder 4 and the radially outward inner surface of the female-thread-forming cylindrical portion 14 of the outer cylinder 5, the inner surface of the cylindrical female-thread-forming cylindrical portion 14 on which the female thread 13 of the outer cylinder 5 is formed is formed further outward than the radially outward inner surface of the female-thread-forming cylindrical portion 14 of the outer cylinder 5, so that the fabric of the garment 2 comes into contact with the radially outward inner surface of the female-thread-forming cylindrical portion 14 of the outer cylinder 5. As a result, even when the outer cylinder 14 is rotated, the tightening force of the screws is less likely to be transmitted to the contact surface of the fabric of the garment 2, and wrinkles in the fabric of the garment 2 can be suppressed, which does not spoil the appearance or damage the fabric of the garment, and also allows the air-conditioned garment blower 1 to be easily removed.

[0039] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. Furthermore, the scope of the present invention is defined by the claims rather than the above description, and it is intended to include all modifications within the meaning and scope of the claims.
