Description

Technical Field

[0001] This invention relates to a lead apron that shields against radiation, and more particularly to a method for reducing the load on the shoulders of a lead apron and a lead apron with waist support for load reduction. Background Technology

[0002] Existing lead aprons are heavy, with the weight transferred downwards by the fabric, placing a heavy burden on the shoulders and spine. Prolonged wear of lead aprons causes muscle strain and joint damage, making shoulder and back pain a common occupational ailment for those using lead aprons. A proposed invention patent application (CN105616013A) describes a lead apron support device with a rear-view design. It includes a waist belt and a T-shaped support frame. A support plate is located in the middle of the waist belt. The bottom of the vertical bar of the T-shaped support frame engages with the support plate. The length of the horizontal bar of the T-shaped support frame is adapted to the shoulder width of the lead apron. In use, the lead apron shoulders rest on the horizontal bar of the T-shaped support frame. The vertical bar of the T-shaped support frame is telescopic. The upper part of the vertical bar of the T-shaped support frame is an arc shape that conforms to the curve of the human neck and back. The horizontal bar of the T-shaped support frame is also an arc shape that conforms to the curve of the human neck and back. In use, medical personnel fasten the waist belt and attach the T-shaped support frame to their lower back. The shoulders of the lead apron are supported on the crossbars of the T-shaped support frame, transferring the pressure of the lead apron on the neck and shoulders to the waist. After trial production and practical application by the applicant, it was found that it did not meet the practical requirements in terms of reducing shoulder load and wearing comfort. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a method for reducing shoulder load with lead apron. This invention also relates to a waist-support lead apron for implementing the method of this invention, which can significantly reduce shoulder load, provide comfortable wear, and meet practical requirements.

[0004] To achieve the above objectives, the present invention provides a lead apron method for reducing shoulder load, characterized in that the lead apron has two V-shaped or at least bifurcated back vertical support plates extending upwards from the waist along the spine to the back shoulder, and any number of pairs of symmetrical left and right side vertical support plates and two symmetrical left and right front vertical support plates arranged symmetrically from the waist upwards from the back vertical support plates on a front-fastening lead apron, or two opposing front vertical support plates arranged on a front-fastening lead apron, or two symmetrical front vertical support plates arranged on a front-fastening lead apron. The apron features two symmetrical front vertical support plates and two opposing side vertical support plates on each side panel. This allows the weight of the lead apron applied to the shoulders to be transferred to a frame-like structure composed of at least three vertical support plates. A waist belt, supporting the waist base of the frame vertical support plates and the lightweight vertical support plates, forms a combined frame, transferring the weight of the lead apron borne by the frame vertical support plates to the waist belt. The waist belt, through fastening, ultimately transfers the load to the load-bearing waist, thus reducing the shoulder load of the lead apron. Preferably, the folded-front lead apron has two opposing front vertical support plates on the inner front panel, or it has two symmetrical front vertical support plates on the inner front panel and opposing side vertical support plates on each side panel. The vertical support plates are non-rigid lightweight plates, such as organic resin plates, acrylic plates, carbon fiber composite plates, or inflatable plates. Organic resin plates include acrylic plates and plastic plates. Lead aprons can be categorized into lightweight extended lead tops, high-protection lead overcoats, ultralight lead vests suitable for non-reproductive individuals, high-protection lead skirts paired with short lead tops, easy-to-wear double-breasted lead aprons, and front-facing folded lead aprons with strong front protection, among others. This lead apron effectively transfers the weight of the shoulders to the lumbosacral region by sewing Y-shaped or V-shaped vertical support plates into the inner back of traditional lead-skin aprons, significantly reducing shoulder pressure, increasing comfort, and alleviating shoulder pain. The invention also includes vertical support plate structures under the armpits and at both front flaps to better transfer the weight of the upper body lead apron and improve protective effectiveness. This design can be used for both two-piece and one-piece lead aprons. For example, a typical approach is a three-layer lead apron consisting of an inner and outer layer and a middle lead-skin layer, with the vertical support plate sewn between the inner and middle lead-skin layers. In other words, the inner layer, the vertical support plate, and the middle lead-skin layer are sewn together, with the vertical support plate confined within the circular seam. In this way, compared with existing technologies, using a lightweight vertical support plate significantly reduces the weight of the vertical support plate attached to the lead apron. The vertical support plate's placement within the slats of the lead apron body also significantly reduces the feeling of foreign objects on the vertical support plate during wear, improving comfort. Compared with existing technologies, the back vertical support plate, with its two upper sloping ends extending to the back shoulder in a V-shape, or at least its upper end branching outwards along the back shoulder to support the back shoulder of the lead apron, significantly increases the load-bearing capacity of the back vertical support plate on the lead apron.Compared to existing technologies, this design features a waist belt supporting the vertical support plates at the base of the lead apron. This integrated support of the belt for both the vertical support plates and the apron itself improves support and reduces shoulder load. The staggered arrangement of the back, side, and front vertical support plates, while easily supported by the waist belt, offers better fit and support adaptability compared to horizontal frames. Therefore, it offers the advantages of significantly reducing shoulder load while providing comfortable wear and high practicality.

[0005] As an optimization, the lead apron has an inner or outer waistband hook or a waistband nose tube at the waist base of the vertical support plate. When worn, an adhesive waistband or a nose-piercing waistband, compatible with the hook or nose tube, is used to support the waistband against the vertical support plate. Alternatively, the waistband is fixed to the middle of the back vertical support plate at the waist base, with the waistband attaching to or passing through the inner or outer waistband hook or nose tube at the waist base of the side and front vertical support plates for support. The waist base of the support plate is fixed to the middle of the back of the waist belt. The waist belt is attached to or passes through the waist base of the lead apron side flap vertical support plate or the front flap vertical support plate. The waist belt supports the vertical support plate by attaching to or passing through the waist belt hook or waist belt nose, or by being fixed to the waist base of the lead apron on the back vertical support plate at the back. After the waist belt is tied, it forms the combined cage of the waist belt and vertical support plate, which reduces the shoulder load of the lead apron when worn. Lead aprons have inner or outer waistband hooks or waistband nose tubes at the waist base of the vertical support plate. When wearing, an adhesive waistband or a nose-piercing waistband is used in conjunction with the hooks or nose tubes. The inner waistband is more comfortable to wear than the outer waistband, while the outer waistband is more convenient to fasten or unfasten as needed. The adhesive waistband is more flexible to fasten, while the nose-piercing waistband is more reliable. Alternatively, the waistband is fixed to the middle back of the waist base of the lead apron at the back vertical support plate. The waistband is attached to or passes through the inner or outer waistband hooks or nose tubes at the waist base of the side or front vertical support plates for waistband support, which allows the lead apron to be loose. Or, the waistband is fixed to the middle back of the waist base of the lead apron at the back vertical support plate. The waistband is attached to or passes through the inner or outer waistband hooks or nose tubes at the waist base of the side or front vertical support plates for waistband support. Installing belt hooks or belt nose tubes inside or outside the lead apron will not affect the integrity of the lead apron protective layer and will help ensure the protective strength.

[0006] Inside the lead apron, the waist belt is fixed to the base of the waist at the back vertical support plate. This prevents the apron from tightening simultaneously when the waist belt is tightened, resulting in a loose fit. The waist belt has a pair of symmetrical vertical support plates fixed to the back center, which are more comfortable than the latter type. Alternatively, there can be a central vertical support plate plus a pair of symmetrical vertical support plates for better lumbar pressure reduction. Or, there can be a wide waist belt with only a central H-shaped vertical support plate, which combines the benefits of lumbar pressure reduction and comfort, as the large support area of ​​the waist belt against the back helps reduce lumbar pressure. The vertical support plates are lightweight. These vertical support plates are non-rigid lightweight plates, such as organic resin plates, acrylic plates, carbon fiber composite plates, inflatable plates, and organic resin plates such as acrylic plates and plastic plates. The central vertical support plate is either vertical strip or H-shaped. The H-shaped vertical support plate provides better support, while the vertical strip type is more comfortable than the former. The left and right symmetrical vertical support plates are H-shaped, which offer better waist comfort and support for the waist belt compared to the former. The wide waist belt is spindle-shaped with a width in the middle greater than the width on both sides, providing better back support and comfort.

[0007] As an optimization, the waist base of the vertical support plate is the same width as the area above the waist base, or the waist base is a side-extending foot waist base extending to one or both sides, so as to increase the support surface of the waist belt on the waist base of the vertical support plate and enhance the support capacity of the waist base on the vertical support plate; the two sides of the back vertical support plate are either a flat extension type to enhance the flat support capacity or a Y-shaped type to facilitate the outward and upward extension of the body. The two sides are either an upper layer provided at the top of the back vertical support plate to provide the shoulder support function, or upper and lower layers provided at the top and middle of the back vertical support plate to provide the shoulder support and middle back support functions. The vertical support plate is either a large-foot or small-foot V-shape. A large-foot V-shape means that the width of the bottom is greater than the width of the sloping arm, the height of the V-shaped indentation is greater than the width of the bottom, and there are horizontal feet on both sides. A small-foot V-shape means that there are no horizontal feet on the above basis. The large-foot V-shape has good waist belt stability, while the small-foot V-shape has good body fit. The side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, which have good support and body fit. Alternatively, they are vertical strips that extend from the waist base to both sides, which have good support stability and even better body fit. Or they are simple vertical strips, which have the best body fit.

[0008] The side extensions and side bifurcations consist of an inner base section and an outer tip section that are pivotally connected, making them easy to adapt to human movement. The pivot axis of the pivot connection is perpendicular to the long axis of the side extensions and side bifurcations, further improving adaptability to human movement. The side extensions and side bifurcations extending from both sides of the back vertical support plate are symmetrical, with two forward-curving outer sections, providing good body conformity. Any straight section of the vertical support plate is an arc-shaped tile section that convexes forward or backward along its long axis, and the arc grooves of adjacent arc-shaped tile sections with the same arc convexity are interconnected, while the arc walls of adjacent arc-shaped tile sections with opposite arc convexities smoothly transition, providing good body conformity and support. The lateral width of the lower layer's two side bifurcations is smaller than that of the upper layer's two side bifurcations, resulting in good body conformity. The outer upper inclined extensions of the Y-shaped upper layer extend laterally to both sides, and the laterally extended sections provide better support compared to the original outer upper inclined extension ends.

[0009] The vertical support plate is either a large-foot or small-foot V-shape. A large-foot V-shape means that the width of the bottom is greater than the width of the sloping arm, the height of the V-shaped indentation is greater than the width of the bottom, and there are horizontal feet on both sides. A small-foot V-shape means that there are no horizontal feet on the above basis. The large-foot V-shape has good waist belt stability, while the small-foot V-shape has good body fit. The side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, which have good support and body fit. Alternatively, they are vertical strips that extend from the waist base to both sides, which have good support stability and even better body fit. Or they are simple vertical strips, which have the best body fit.

[0010] As an optimization, the waist base of the vertical support plate is the same width as the area above the waist base, or the waist base is a side-extending foot waist base extending to one or both sides, so as to increase the support surface of the waist belt on the waist base of the vertical support plate and enhance the support capacity of the waist base on the vertical support plate; the two sides of the back vertical support plate are either a flat extension type to enhance the flat support capacity or a Y-shaped type to facilitate the outward and upward extension of the body. The two sides are either an upper layer provided at the top of the back vertical support plate to provide the shoulder support function, or upper and lower layers provided at the top and middle of the back vertical support plate to provide the shoulder support and middle back support functions. The waist base of the vertical support plate is the same width as the area above it, occupying little space in the lead apron and providing good comfort. Alternatively, the waist base can be a side-extending leg waist base extending to one or both sides, resulting in a large connection surface for the waist belt and high connection strength. The two side branches of the back vertical support plate are either horizontally extending, providing a large support surface, or Y-shaped with an outward and upward sloping extension, offering better fit than the aforementioned horizontal type. The two side branches are an upper layer located at the top of the back vertical support plate, providing high support efficiency for the lead apron, or two layers located at the top and middle of the back vertical support plate, providing strong support for the lead apron. The lateral width of the lower layer's two side branches is smaller than that of the upper layer's two side branches, resulting in good body fit. The side extensions and side branches consist of an inner base section and an outer slight section that are pivotally connected, easily adapting to human movement. The pivot axis of the pivot connection is perpendicular to the long axis of the side extensions and side branches, further improving adaptability to human movement. The side extensions and side branches extending from both sides of the back vertical support plate are symmetrical, with two forward-curving outer sections, providing good body fit. Each straight section of the vertical support plate is an arc-shaped tile segment that convexes forward or backward along its long axis. The arc grooves of adjacent arc-shaped tile segments with the same convex direction are interconnected, while the arc walls of adjacent arc-shaped tile segments with opposite convex directions smoothly transition, resulting in good body support. The lateral width of the bifurcations on both sides of the lower layer is smaller than that of the bifurcations on both sides of the upper layer, ensuring good body conformity. The Y-shaped upper layer's outer upper oblique extensions extend laterally to both sides, and these laterally extended sections offer better support compared to the original outer upper oblique extensions. The vertical support plate is either a large-foot or small-foot V-shape. A large-foot V-shape means that the width of the bottom is greater than the width of the sloping arm, the height of the V-shaped indentation is greater than the width of the bottom, and there are horizontal feet on both sides. A small-foot V-shape means that there are no horizontal feet on the above basis. The large-foot V-shape has good waist belt stability, while the small-foot V-shape has good body fit. The side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, which have good support and body fit. Alternatively, they are vertical strips that extend from the waist base to both sides, which have good support stability and even better body fit. Or they are simple vertical strips, which have the best body fit.

[0011] As an optimization, the lead apron or jacket can be equipped with a Y-shaped or V-shaped back vertical support plate, symmetrical vertical stripe side vertical support plates, and symmetrical vertical stripe front vertical support plates that are longer than the side vertical support plates. Alternatively, the lead apron or jacket can be equipped with a V-shaped or V-shaped top layer with forked sides and a middle layer with forked sides, symmetrical vertical stripe side vertical support plates, and symmetrical V-shaped front vertical support plates that are longer than the side vertical support plates. Alternatively, the lead apron or jacket can be equipped with a Y-shaped or V-shaped back vertical support plate and... Two opposing vertical support plates are set on the inner or outer folded front panels, or Y-shaped or V-shaped back vertical support plates are set on the folded coat or upper body lead apron, and two opposing vertical support plates are set on the inner or outer folded front panels and symmetrical side panel vertical support plates are set on the side panels; so as to transfer part of the weight of the lead apron applied to the shoulders to the combined frame vertical support plates; and the waist base of the combined frame vertical support plates is supported by the waist belt to form a combined cage frame of waist belt vertical support plates, so as to transfer the weight of the lead apron borne by the combined frame vertical support plates to the waist belt.

[0012] Among them, the extended upper lead apron worn independently is equipped with the aforementioned vertical support plate to reduce the load on the waist belt of the upper lead apron; or the short upper lead apron with the aforementioned vertical support plate is worn with a skirt lead apron with its own waist belt to enhance the radiation protection of the overlapping part of the upper lead apron and the skirt lead apron and to share the load of the upper lead apron with the skirt lead apron. Among them, the double-breasted coat or upper lead apron is equipped with a Y-shaped or wide-leg V-shaped back vertical support plate, or the double-breasted coat or upper lead apron is equipped with a Y-shaped or wide-leg V-shaped back vertical support plate and symmetrical vertical strip side flap vertical support plates and symmetrical vertical strip front flap vertical support plates that are longer than the side flap vertical support plates. The former only has a back vertical support plate compared to the latter having all of them, which has better wearing mobility, and the latter has better shoulder load reduction compared to the former; or the double-breasted coat or upper lead apron is equipped with a V-shaped or wide-leg V-shaped top layer branching on both sides and a middle layer branching on both sides back vertical support plate and symmetrical vertical strip side flap vertical support plates. And the large-footed V-shaped front vertical support plate, which is symmetrical on both sides and higher than the side vertical support plate, provides good overall shoulder load reduction; or the folded-front coat or lead apron is equipped with a Y-shaped or large-footed V-shaped back vertical support plate and two opposite front vertical support plates on the inner or outer folded front, which can reduce the shoulder load in front and back, and also provides good left and right bending mobility; or the folded-front coat or lead apron is equipped with a Y-shaped or large-footed V-shaped back vertical support plate and two opposite front vertical support plates on the inner or outer folded front, and symmetrical side vertical support plates on both sides; the front protection is strong and the overall shoulder load reduction is good. Among them, the extended upper lead apron with the aforementioned vertical support plate, compared with the large lead apron, can significantly reduce the weight of the lead apron and the burden on the shoulders, and can also shield and protect all sensitive organs of the body; or the short upper lead apron with the aforementioned vertical support plate, worn with a skirt lead apron with its own waist belt, compared with the extended upper lead apron, can significantly reduce the weight of the lead apron and the burden on the shoulders, but the protective strength can still be comparable to that of the large lead apron.

[0013] As an optimization, the vertical support plate is an airbag vertical support plate filled with pressurized gas, or an inflatable or pressurized airbag vertical support plate is replaced and installed on the lead apron, or the airbag vertical support plate is inflatable, and all inflatable airbag vertical support plates are individually connected to an air supply valve or are connected to a common air supply valve and are equipped with an easy-connect air nozzle, or all inflatable airbag vertical support plates are individually connected to an air supply valve or are connected to a common air supply valve and are equipped with a portable air pump through an easy-connect air nozzle; the airbag vertical support plate is supported by the air column formed by the whole, and the compressibility and deformability of the air column ensures comfort, and further, the compressibility and bending deformation of the air column ensures comfort.

[0014] The waist-supported lead apron used to implement the lead apron weight reduction method of the present invention is characterized in that the back panel of the lead apron has two V-shaped or at least bifurcated back vertical support plates extending upward from the waist along the mid-spine to the back shoulder, or at least the upper end of which bifurcates to both sides along the back shoulder. This facilitates modification without affecting the main structure of the existing lead apron. Compared with the bifurcated type, the V-shaped lead apron is more loose in the back spine area and the support plates have better back support, making it more comfortable to wear. The two upward-extending plates also provide better support for back movement. The double-breasted lead apron has any number of pairs of symmetrical left and right side vertical support plates and two symmetrical front vertical support plates symmetrically arranged from the back vertical support plates forward from the waist. When only the side vertical support plates or only the two front vertical support plates are used on the basis of the back vertical support plates, it is convenient to move around. When both the side vertical support plates and the two front vertical support plates are used on the basis of the back vertical support plates, the shoulder load can be reduced to the maximum extent. Alternatively, a lead apron with a folded front flap can have two opposing vertical support plates on one front flap. When worn, the two front flaps are buttoned or fastened together, and the two front flap vertical support plates can also provide auxiliary support to the other front flap to reduce the shoulder load. Folding the front flap can double the front protection capability. Alternatively, a lead apron with a folded front flap can have two symmetrical front flap vertical support plates on one front flap and opposing side flap vertical support plates on each side flap. When worn, the two front flaps are buttoned or fastened together, and the two front flap vertical support plates can also provide auxiliary support to the other front flap to reduce the shoulder load. Folding the front flap can double the front protection capability. The introduction of opposing side flap vertical support plates can further reduce the shoulder load to the maximum extent. The vertical support plates are lightweight plates. The waist base of the frame-type vertical support plate composed of at least three vertical support plates is supported by a waist belt to form a waist belt vertical support plate combination cage. The load-bearing capacity of the frame vertical support plate that shares the shoulder load is transferred to the waist of the lead apron wearer through the tied waist belt. The preferred type of lead apron features two opposing vertical support plates on the inner front panel, or two symmetrical vertical support plates on the inner front panel and opposing vertical support plates on the side panels. These vertical support plates are made of lightweight, non-rigid materials such as acrylic, carbon fiber composite, or inflatable bladder panels. Other types of lead aprons can include lightweight extended lead jackets, high-protection lead overcoats, ultralight lead vests suitable for non-reproductive individuals, high-protection lead skirts and short lead jackets, easy-to-wear double-breasted lead aprons, and front-facing folded lead aprons with high protection. This lead apron effectively transfers shoulder weight to the lumbosacral region through the support plates and a dedicated waistband by sewing Y-shaped or V-shaped inner back vertical support plates into the traditional lead rubber apron, significantly reducing shoulder pressure, increasing comfort, and alleviating shoulder pain symptoms. The invention also includes vertical support plates under the armpits and at the front of the garment to better transfer the weight of the lead apron to the upper body and improve the protective effect. This design can be used for both two-piece and one-piece lead aprons.For example, a typical design is a three-layer lead apron consisting of an inner and outer layer and a middle lead rubber layer. The vertical support plate is sewn between the inner and middle lead rubber layers, effectively connecting the inner layer, the vertical support plate, and the middle lead rubber layer together, confining the vertical support plate within the circular seam. Compared to existing technologies, this lightweight vertical support plate significantly reduces the weight of the apron itself. Its integration into the apron's structure also reduces the feeling of foreign objects on the plate, improving comfort. Compared to existing technologies, a V-shaped back vertical support plate extending to the back shoulder with two upward-sloping ends, or at least branching outwards from the back shoulder at the upper end, provides structural support to the back shoulder, significantly increasing the load-bearing capacity of the back vertical support plate. Finally, compared to existing technologies, a waist belt supports the vertical support plate at the waist base, providing integrated support for both the vertical support plate and the apron itself, further enhancing support and reducing shoulder load. The staggered arrangement of the back vertical support plate, side vertical support plates, and front vertical support plate allows for easy support by the waist belt, while also providing better fit and support compared to the horizontal frame. Therefore, it offers the advantages of significantly reducing shoulder load while maintaining comfortable wear and high practicality.

[0015] As an optimization, the lead apron has an inner or outer belt hook or nose tube at the waist base of the vertical support plate. When worn, an adhesive belt or nose-piercing belt, compatible with the hook or nose tube, is used to support the belt against the vertical support plate. The inner belt is more comfortable to wear than the outer belt, while the outer belt allows for easy fastening or unfastening as needed. The adhesive belt is more flexible, while the nose-piercing belt is more reliable. Alternatively, the lead apron can be fixed at the waist base of the back vertical support plate. The waist belt is secured to the back center of the lead apron. It is attached to or passes through the vertical support plates on the side and front panels, with the waist belt hooks or nose tubes located inside or outside the apron for support. This allows the lead apron to fit loosely. Alternatively, the waist belt can be fixed to the back center of the lead apron at the base of the back vertical support plate. The waist belt is then attached to or passes through the vertical support plates on the side or front panels, with the waist belt hooks or nose tubes located inside or outside the apron for support. Using waist belt hooks or nose tubes inside or outside the lead apron does not affect the integrity of the protective layer and helps ensure protective strength.

[0016] Inside the lead apron, the waist belt is fixed to the base of the waist at the back vertical support plate. This prevents the apron from tightening simultaneously when the waist belt is tightened, resulting in a loose fit. The waist belt has a pair of symmetrical vertical support plates fixed to the back center, which are more comfortable than the latter type. Alternatively, there can be a central vertical support plate plus a pair of symmetrical vertical support plates for better lumbar pressure reduction. Or, there can be a wide waist belt with only a central H-shaped vertical support plate, which combines the benefits of lumbar pressure reduction and comfort, as the large support area of ​​the waist belt against the back helps reduce lumbar pressure. The vertical support plates are lightweight. These vertical support plates are non-rigid lightweight plates, such as organic resin plates, acrylic plates, carbon fiber composite plates, inflatable plates, and organic resin plates such as acrylic plates and plastic plates. The central vertical support plate is either vertical strip or H-shaped. The H-shaped vertical support plate provides better support, while the vertical strip type is more comfortable than the former. The left and right symmetrical vertical support plates are H-shaped, which offer better waist comfort and support for the waist belt compared to the former. The wide waist belt is spindle-shaped with a width in the middle greater than the width on both sides, providing better back support and comfort.

[0017] As an optimization, the waist base of the vertical support plate is the same width as the area above the waist base, or the waist base is a side-extending leg waist base extending to one or both sides; the two side branches of the back vertical support plate are either a flat extension type to enhance the flat support capacity or a Y-shape to facilitate the outward and upward extension of the body. The two side branches are either an upper layer provided at the top of the back vertical support plate to provide the shoulder support function, or two upper and lower layers provided at the top and middle of the back vertical support plate to provide the shoulder support and middle back support function. The lateral width of the lower side branches is smaller than the lateral width of the upper side branches; the vertical support plate is a V-shaped plate with large or small feet, the side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, or are vertical strips with side-extending legs extending from the waist base to both sides, or are simple vertical strips.

[0018] The waist base of the vertical support plate is the same width as the area above the waist base, occupying little lead apron surface and providing good comfort. Alternatively, the waist base can be a side-extending leg waist base extending to one or both sides, resulting in a large connection surface for the waist belt and high connection strength. The two side branches of the back vertical support plate are either horizontally extending, providing a large support surface, or Y-shaped with an outward and upward sloping extension, offering better fit than the aforementioned horizontally extending type. The two side branches can be an upper layer set at the top of the back vertical support plate, providing high support efficiency for the lead apron, or two layers set at the top and middle of the back vertical support plate, providing strong support for the lead apron. The lateral width of the lower layer's two side branches is smaller than the lateral width of the upper layer's two side branches, resulting in good fit.

[0019] The side extensions and side bifurcations consist of an inner base section and an outer tip section that are pivotally connected, making them easy to adapt to human movement. The pivot axis of the pivot connection is perpendicular to the long axis of the side extensions and side bifurcations, further improving adaptability to human movement. The side extensions and side bifurcations extending from both sides of the back vertical support plate are symmetrical, with two forward-curving outer sections, providing good body conformity. Any straight section of the vertical support plate is an arc-shaped tile section that convexes forward or backward along its long axis, and the arc grooves of adjacent arc-shaped tile sections with the same arc convexity are interconnected, while the arc walls of adjacent arc-shaped tile sections with opposite arc convexities smoothly transition, providing good body conformity and support. The lateral width of the lower layer's two side bifurcations is smaller than that of the upper layer's two side bifurcations, resulting in good body conformity. The outer upper inclined extensions of the Y-shaped upper layer extend laterally to both sides, and the laterally extended sections provide better support compared to the original outer upper inclined extension ends.

[0020] The vertical support plate is either a large-foot or small-foot V-shape. A large-foot V-shape means that the width of the bottom is greater than the width of the sloping arm, the height of the V-shaped indentation is greater than the width of the bottom, and there are horizontal feet on both sides. A small-foot V-shape means that there are no horizontal feet on the above basis. The large-foot V-shape has good waist belt stability, while the small-foot V-shape has good body fit. The side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, which have good support and body fit. Alternatively, they are vertical strips that extend from the waist base to both sides, which have good support stability and even better body fit. Or they are simple vertical strips, which have the best body fit.

[0021] As an optimization, the lead apron or jacket can be equipped with a Y-shaped or V-shaped back vertical support plate, symmetrical vertical stripe side vertical support plates, and symmetrical vertical stripe front vertical support plates that are longer than the side vertical support plates. Alternatively, the lead apron or jacket can be equipped with a V-shaped or V-shaped top layer with two forks on both sides and a middle layer with two forks on both sides, symmetrical vertical stripe side vertical support plates, and symmetrical V-shaped front vertical support plates that are longer than the side vertical support plates. Alternatively, a lead apron or jacket with folded front panels may be equipped with Y-shaped or V-shaped back vertical support plates and two opposing front vertical support plates on the inner or outer folded front panels; or a lead apron or jacket with folded front panels may be equipped with Y-shaped or V-shaped back vertical support plates and two opposing front vertical support plates on the inner or outer folded front panels and two symmetrical side vertical support plates on the side panels; the waist base of the frame-like vertical support plates composed of vertical support plates is supported by a waist belt to form a combined waist belt and vertical support plate cage. The extended upper lead apron worn independently features the aforementioned vertical support plate, or the short upper lead apron with the aforementioned vertical support plate is worn with a skirt lead apron that comes with its own waist belt, to ensure radiation protection while reducing the load on the upper lead apron waist belt. Specifically, the double-breasted coat or upper lead apron features a Y-shaped or wide-legged V-shaped back vertical support plate, or a double-breasted coat or upper lead apron features a Y-shaped or wide-legged V-shaped back vertical support plate and symmetrical vertical stripe side flap vertical support plates, as well as symmetrical vertical stripe front flap vertical support plates longer than the side flap vertical support plates. The former only has a back vertical support plate, while the latter has all of them, offering better wearing freedom of movement; the latter, compared to the former, reduces shoulder load. Alternatively, the double-breasted coat or upper lead apron features a V-shaped or wide-legged V-shaped top layer with two branching sides and a middle layer with two branching sides, along with symmetrical vertical stripe side flap vertical support plates. And the large-footed V-shaped front vertical support plate, which is symmetrical on both sides and higher than the side vertical support plate, provides good overall shoulder load reduction; or the folded-front coat or lead apron is equipped with a Y-shaped or large-footed V-shaped back vertical support plate and two opposite front vertical support plates on the inner or outer folded front, which can reduce the shoulder load in front and back, and also provides good left and right bending mobility; or the folded-front coat or lead apron is equipped with a Y-shaped or large-footed V-shaped back vertical support plate and two opposite front vertical support plates on the inner or outer folded front, and symmetrical side vertical support plates on both sides; the front protection is strong and the overall shoulder load reduction is good. Among them, the extended upper lead apron with the aforementioned vertical support plate, compared with the large lead apron, can significantly reduce the weight of the lead apron and the burden on the shoulders, and can also shield and protect all sensitive organs of the body; or the short upper lead apron with the aforementioned vertical support plate, worn with a skirt lead apron with its own waist belt, compared with the extended upper lead apron, can significantly reduce the weight of the lead apron and the burden on the shoulders, but the protective strength can still be comparable to that of the large lead apron.

[0022] As an optimization, the vertical support plate is an airbag vertical support plate filled with pressurized gas, which has good adaptability to body deformation and vertical support to meet the support requirements. The inflatable or pressurized gas-filled airbag vertical support plate is installed on the lead apron in a replaceable manner. The replaceable airbag pocket is equipped with a pocket cover or pocket door with a lockable pocket opening. This allows for the replacement of different materials and air pressure specifications of the airbag vertical support to better meet the needs of reducing shoulder load and comfort. The airbag vertical support plate is inflatable. All inflatable airbag vertical support plates have individual air supply valves or are connected to a common air supply valve and are equipped with easy-connect air nozzles. This allows for the configuration of a dedicated inflation device at the use site for precise inflation when needed. All inflatable airbag vertical support plates have individual air supply valves or are connected to a common air supply valve and are equipped with a portable inflation pump through an easy-connect air nozzle. The portable inflation pump can be carried for inflation or pre-placed nearby for on-site or portable inflation when needed. Compared to a pure plate design, it significantly improves body fit and comfort. The airbag vertical support plate has sufficient vertical support strength without being rigid, and it can deform under compression for a comfortable fit.

[0023] After adopting the above technical solution, the lead apron method for reducing shoulder load and the waist-support lead apron of the present invention have the advantages of significantly reducing shoulder load, improving wearing comfort and fit, and promoting perspiration, and are highly practical.

Detailed Implementation

[0025] The method for reducing shoulder burden in lead aprons of the present invention involves a V-shaped or at least bifurcated back vertical support plate extending upwards from the waist along the spine to the back shoulder on the back panel, and any number of pairs of symmetrical left and right side vertical support plates and two symmetrical left and right front vertical support plates arranged symmetrically from the waist upwards on the front panel of the lead apron, or a lead apron with a folded front panel having two opposing front vertical support plates on one front panel, or a lead apron with a folded front panel having two symmetrical left and right front vertical support plates on one front panel. Two front-panel vertical support plates and two side-panel vertical support plates arranged opposite each other on the side panels are used to transfer part of the weight of the lead apron applied to the shoulders to the frame-like vertical support plates composed of at least three vertical support plates. A waist belt-supported vertical support plate cage is formed by lightweight vertical support plates and the waist base of the frame-like vertical support plates, transferring the weight of the lead apron borne by the frame-like vertical support plates to the waist belt. The waist belt, through fastening, ultimately transfers the load to the load-bearing waist, thereby reducing the shoulder load of the lead apron. Preferably, the folded front-panel lead apron has two front-panel vertical support plates arranged opposite each other on the inner front panel, or the folded front-panel lead apron has two symmetrical front-panel vertical support plates on the inner front panel and two side-panel vertical support plates arranged opposite each other on the side panels. The vertical support plates are non-rigid lightweight plates, such as organic resin plates, acrylic plates, carbon fiber composite plates, inflatable bladder plates, and organic resin plates such as acrylic plates and plastic plates. Lead aprons can be categorized into lightweight extended lead tops, high-protection lead overcoats, ultralight lead vests suitable for non-reproductive individuals, high-protection lead skirts paired with short lead tops, easy-to-wear double-breasted lead aprons, and front-facing folded lead aprons with strong front protection, among others. This lead apron effectively transfers the weight of the shoulders to the lumbosacral region by sewing Y-shaped or V-shaped vertical support plates into the inner back of traditional lead-skin aprons, significantly reducing shoulder pressure, increasing comfort, and alleviating shoulder pain. The invention also includes vertical support plate structures under the armpits and at both front flaps to better transfer the weight of the upper body lead apron and improve protective effectiveness. This design can be used for both two-piece and one-piece lead aprons. For example, a typical approach is a three-layer lead apron consisting of an inner and outer layer and a middle lead-skin layer, with the vertical support plate sewn between the inner and middle lead-skin layers. In other words, the inner layer, the vertical support plate, and the middle lead-skin layer are sewn together, with the vertical support plate confined within the circular seam. In this way, compared with existing technologies, using a lightweight vertical support plate significantly reduces the weight of the vertical support plate attached to the lead apron. The vertical support plate's integration into the slats of the lead apron body significantly reduces the feeling of foreign objects on the vertical support plate during wear, improving comfort. Compared with existing technologies, the back vertical support plate, with its two upper sloping ends extending to the back shoulder in a V-shape, or at least its upper end branching out to both sides along the back shoulder, provides structural support to the back shoulder of the lead apron, significantly increasing the load-bearing capacity of the back vertical support plate on the shoulders. Compared with existing technologies, the waist base where the vertical support plate is located on the lead apron body is supported by a waist belt, achieving integrated support of the waist belt for both the vertical support plate and the lead apron body during wear, which is beneficial for improving support and reducing shoulder load performance.The staggered arrangement of the back vertical support plate, side vertical support plates, and front vertical support plate allows for easy support by the waist belt, while also providing better fit and support compared to the horizontal frame. Therefore, it offers the advantages of significantly reducing shoulder load while maintaining comfortable wear and high practicality.

[0026] Specifically, the lead apron has an inner or outer waistband hook or a waistband nose tube at the waist base of the vertical support plate. When worn, an adhesive waistband or a waistband with a nose tube, used in conjunction with the hook or tube, supports the waistband against the vertical support plate. Alternatively, the lead apron has a waistband fixed to the middle of the back vertical support plate at the waist base. The waistband is attached to or passes through the inner or outer waistband hook or nose tube at the waist base of the side and front vertical support plates of the lead apron for support. The waist base of the board is fixed to the middle of the back of the waist belt. The waist belt is attached to or passes through the waist base of the lead apron side flap vertical support plate or the front flap vertical support plate. The waist belt supports the vertical support plate by attaching to or passing through the waist belt hook or waist belt nose tube, or by attaching to the lead apron at the waist base of the back vertical support plate at the middle of the back. After the waist belt is tied, it forms the combined cage of the waist belt and vertical support plate, which plays the role of reducing the shoulder load of the lead apron when worn.

[0027] Inside the lead apron, a waist belt is fixed to the waist base of the back vertical support plate. The waist belt is a wide belt with a pair of symmetrical left and right vertical support plates fixed to the back center, or a central vertical support plate plus a pair of symmetrical left and right vertical support plates, or only a central H-shaped vertical support plate. The vertical support plates are lightweight plates. The central vertical support plate is vertical strip-shaped or H-shaped, and the symmetrical left and right vertical support plates are H-shaped. The wide waist belt is spindle-shaped with the central width greater than the width of the sides. The vertical support plates are V-shaped with large or small feet, or I-shaped with high vertical arms and short horizontal arms, or vertical strips extending to both sides from the waist base, or simply vertical strips.

[0028] The side extensions and side bifurcations consist of an inner base section and an outer tip section that are pivotally connected, making them easy to adapt to human movement. The pivot axis of the pivot connection is perpendicular to the long axis of the side extensions and side bifurcations, further improving adaptability to human movement. The side extensions and side bifurcations extending from both sides of the back vertical support plate are symmetrical, with two forward-curving outer sections, providing good body conformity. Any straight section of the vertical support plate is an arc-shaped tile section that convexes forward or backward along its long axis, and the arc grooves of adjacent arc-shaped tile sections with the same arc convexity are interconnected, while the arc walls of adjacent arc-shaped tile sections with opposite arc convexities smoothly transition, providing good body conformity and support. The lateral width of the lower layer's two side bifurcations is smaller than that of the upper layer's two side bifurcations, resulting in good body conformity. The outer upper inclined extensions of the Y-shaped upper layer extend laterally to both sides, and the laterally extended sections provide better support compared to the original outer upper inclined extension ends.

[0029] Specifically, the waist base of the vertical support plate is the same width as the area above it, or the waist base is a side-extending leg waist base extending to one or both sides, to increase the support surface of the waist belt on the waist base of the vertical support plate and enhance the support capacity of the waist base for the vertical support plate; the two side branches of the back vertical support plate are either flat extensions to enhance the flat support capacity or Y-shaped extensions to facilitate body movement. The two side branches are either an upper layer provided at the top of the back vertical support plate to provide shoulder support, or upper and lower layers provided at the top and middle of the back vertical support plate to provide shoulder support and middle back support. The side extensions and side branches are composed of an inner base section and an outer tip section that are pivotally connected, which easily adapts to human movement. The pivot axis of the pivot connection is perpendicular to the long axis of the side extensions and side branches, which better adapts to human movement. The side extensions and side branches extending on both sides of the back vertical support plate are symmetrical, forward-curving extensions of two outer sections, which provides good body movement. Each straight section of the vertical support plate is an arc-shaped tile segment that convexes forward or backward along its long axis. The arc grooves of adjacent arc-shaped tile segments with the same convex direction are interconnected, while the arc walls of adjacent arc-shaped tile segments with opposite convex directions smoothly transition, resulting in good body support. The lateral width of the bifurcations on both sides of the lower layer is smaller than that of the bifurcations on both sides of the upper layer, ensuring good body conformity. The Y-shaped upper layer's outer upper oblique extensions extend laterally to both sides, and these laterally extended sections offer better support compared to the original outer upper oblique extensions. The vertical support plate is either a large-foot or small-foot V-shape. A large-foot V-shape means that the width of the bottom is greater than the width of the sloping arm, the height of the V-shaped indentation is greater than the width of the bottom, and there are horizontal feet on both sides. A small-foot V-shape means that there are no horizontal feet on the above basis. The large-foot V-shape has good waist belt stability, while the small-foot V-shape has good body fit. The side flap vertical support plate and the front flap vertical support plate are I-shaped with high vertical arms and short horizontal arms, which have good support and body fit. Alternatively, they are vertical strips that extend from the waist base to both sides, which have good support stability and even better body fit. Or they are simple vertical strips, which have the best body fit.

[0030] Specifically, the lead apron or jacket with a front opening is equipped with a Y-shaped or V-shaped back vertical support plate and symmetrical vertical stripe side vertical support plates, as well as symmetrical vertical stripe front vertical support plates that are longer than the side vertical support plates. Alternatively, the lead apron or jacket with a front opening is equipped with a V-shaped or V-shaped top layer with two forks on both sides and a middle layer with two forks on both sides, symmetrical vertical stripe side vertical support plates, and symmetrical V-shaped front vertical support plates that are longer than the side vertical support plates. Alternatively, the lead apron with a folded front opening is equipped with a Y-shaped or V-shaped back vertical support plate and an inner... Alternatively, two opposing vertical support plates can be installed on the outer folded front placket, or Y-shaped or V-shaped vertical support plates can be installed on the back of the folded coat or upper garment lead apron, and two opposing vertical support plates can be installed on the inner or outer folded front placket, and symmetrical vertical support plates can be installed on the side plackets; this allows part of the weight of the lead apron applied to the shoulders to be transferred to the combined frame-type vertical support plates; and the waist base of the combined frame vertical support plates is supported by the waist belt to form a combined cage frame of waist belt vertical support plates, thereby transferring the weight of the lead apron borne by the combined frame vertical support plates to the waist belt.

[0031] The extended upper lead apron worn independently is equipped with the aforementioned vertical support plate to reduce the load on the upper lead apron waist belt; or the short upper lead apron equipped with the aforementioned vertical support plate is worn with a skirt lead apron with its own skirt waist belt to enhance radiation protection of the overlapping part of the upper lead apron and the skirt lead apron to share the load of the upper lead apron.

[0032] Specifically, the vertical support plate is an airbag vertical support plate filled with pressurized gas, or an inflatable or pressurized airbag vertical support plate is installed on the lead apron in a replaceable manner, or the airbag vertical support plate is inflatable, and all inflatable airbag vertical support plates are individually connected to an air supply valve or are connected to a common air supply valve and are equipped with an easy-connect air nozzle, or all inflatable airbag vertical support plates are individually connected to an air supply valve or are connected to a common air supply valve and are equipped with a portable air pump through an easy-connect air nozzle; the airbag vertical support plate is supported by an integrally formed air column, and the compressibility and deformability of the air column ensures comfort, and further, the compressibility and bending deformation of the air column ensures comfort.

[0033] Example 1, as Figure 1-2As shown, the waist-branching lead apron of the lead apron method for reducing shoulder load using this invention includes a lead apron and support plates. The lead apron has a back vertical support plate 2 extending upwards from the waist along the spine, with its upper end branching outwards to both sides past the shoulders. Specifically, the button-down, sleeveless lead coat-style lead apron 11 has two symmetrically spaced vertical support plates 21 and two symmetrical vertical support plates 22 extending upwards from the waist from the back vertical support plate 2. The vertical support plates are lightweight. The waist base of the five vertical support plates forming a frame-like structure is supported by a waist belt, forming a combined frame. The load-bearing capacity of the frame vertical support plates, which share the shoulder load, is transferred to the waist of the lead apron wearer through the tied waist belt. The vertical support plates are non-rigid, lightweight plates, such as organic resin plates, acrylic plates, carbon fiber composite plates, or inflatable bladder plates. Organic resin plates include acrylic plates and plastic plates. Lead aprons can be categorized into lightweight extended lead tops, high-protection lead overcoats, ultralight lead vests suitable for non-reproductive individuals, high-protection lead skirts paired with short lead tops, easy-to-wear double-breasted lead aprons, and front-facing folded lead aprons with strong front protection, among others. This lead apron effectively transfers the weight of the shoulders to the lumbosacral region by sewing Y-shaped or V-shaped vertical support plates into the inner back of traditional lead-skin aprons, significantly reducing shoulder pressure, increasing comfort, and alleviating shoulder pain. The invention also includes vertical support plate structures under the armpits and at both front flaps to better transfer the weight of the upper body lead apron and improve protective effectiveness. This design can be used for both two-piece and one-piece lead aprons. For example, a typical approach is a three-layer lead apron consisting of an inner and outer layer and a middle lead-skin layer, with the vertical support plate sewn between the inner and middle lead-skin layers. In other words, the inner layer, the vertical support plate, and the middle lead-skin layer are sewn together, with the vertical support plate confined within the circular seam. In this way, compared with existing technologies, using a lightweight vertical support plate significantly reduces the weight of the vertical support plate attached to the lead apron. The vertical support plate's integration into the slats of the lead apron body significantly reduces the feeling of foreign objects on the vertical support plate during wear, improving comfort. Compared with existing technologies, the back vertical support plate, with its two upper sloping ends extending to the back shoulder in a V-shape, or at least its upper end branching out to both sides along the back shoulder, provides structural support to the back shoulder of the lead apron, significantly increasing the load-bearing capacity of the back vertical support plate. Compared with existing technologies, the waist base of the vertical support plate, where it is located on the lead apron body, is supported by a waist belt, achieving integrated support of the waist belt for both the vertical support plate and the lead apron body during wear, which is beneficial for improving support and reducing shoulder load. The spaced arrangement of the back vertical support plate, side vertical support plates, and front vertical support plate, while easily supported by the waist belt, offers better fit and support adaptability compared to the horizontal frame. Therefore, it has the advantages of significantly reducing shoulder load, providing comfortable wear, and being highly practical.

[0034] Specifically, the lead apron is sewn with vertical support plates, and an outer waistband nose tube 4 is installed at the waist base of the vertical support plates. When worn, a nose-piercing waistband that matches the waistband nose tube 4 is used to support the vertical support plates. The two sides of this back vertical support plate 2 are Y-shaped, extending outward and upward. That is, the double-breasted lead apron has a Y-shaped back vertical support plate 2, symmetrical vertical strip side flap vertical support plates 21, and symmetrical vertical strip front flap vertical support plates 22 that are longer than the side flap vertical support plates.

[0035] Example 2, as Figure 3 As shown, the waist-bracing lead apron used in the present invention to realize the method of reducing shoulder load is different from the above embodiment 1 in that it is an independent upper garment type lead vest 12 that provides simple protection for people who do not need reproductive needs. The lead apron has a waist belt hook piece 41 inside the waist base of the vertical support plate. When wearing it, the adhesive belt that is matched with the waist belt hook piece 41 is used.

[0036] like Figure 4 As shown, the first vertical support plate from the left has two outwardly extending Y-shaped branches on both sides, with the branches forming two layers at the top and middle of the back vertical support plate. Furthermore, the lateral width of the lower layer's branches is smaller than that of the upper layer's branches. The base of this vertical support plate has side extensions extending to both sides. The second vertical support plate from the left has a large-foot V-shape. The third vertical support plate from the left has an I-shape with a high vertical arm and a short horizontal arm. The fourth vertical support plate from the left is a vertical strip plate with side extensions extending from the base to both sides. The fifth vertical support plate from the left is a simple vertical strip plate.

[0037] like Figure 5-6 As shown, the back vertical support plate 2 has two forked, upwardly extending Y-shaped sections. These two forks form an upper layer at the top of the back vertical support plate 2. The side extensions and side forks are composed of an inner base section and an outer end section that are pivotally connected. The side extensions and side forks extending from both sides of the back vertical support plate 2 are symmetrical, forward-curving arc-shaped sections.

[0038] Example 3, as Figure 7 As shown, the waist-bracing lead apron used in this invention to reduce shoulder load differs from embodiments one and two above in that it features a V-shaped top layer with two bifurcated sides and a V-shaped middle layer with two bifurcated sides, symmetrical vertical side panel support plates 21, and symmetrical V-shaped front panel support plates 22 that are higher than the side panel support plates. The vertical support plates are pressurized gas-filled airbag support plates. Preferably, the pressurized gas-filled airbag support plates are replaceable on the lead apron; more preferably, the airbag support plates are inflatable, and all airbag support plates are connected to a gas supply pipe 3 valve 30 and equipped with an easy-connect air nozzle 31. The waist base of all vertical support plates is a side-extending foot waist base extending to both sides. The airbag support plates have sufficient vertical support strength without being rigid, allowing for deformation under pressure and providing comfort.

[0039] Example 4, as Figure 8 As shown, the waist-bracing lead apron used in this invention to reduce shoulder load differs from the one described in Embodiment 3 in that it features a V-shaped (or Y-shaped) back support plate 2, symmetrical vertical side support plates, and symmetrical vertical front support plates longer than the side support plates. The vertical support plates are airbag-shaped support plates filled with pressurized gas. All airbag support plates are connected to an air supply pipe 3 valve 30 and connected to a portable air pump 32 via an easy-to-access air nozzle 31. The airbag support plates provide sufficient vertical support strength without being rigid, allowing for deformation under pressure and providing comfort.

[0040] Example 5, as Figure 9 As shown, the waist-bracing lead apron used in this invention to achieve the lead apron load reduction method differs from the one in Embodiment 2 above in that the folded-front lead overcoat 13 is equipped with an attachment. Figure 5-6 The display shows a Y-shaped (or V-shaped) back support plate 2 and two opposing front flap support plates 22 on the left inner flap. No side support plates are provided. The left inner flap and right outer flap are tightly fastened together by an outer adhesive tape and an inner hook-and-loop tape 41, respectively.

[0041] The lead apron is fixed to the waist belt 5 at the waist base of the back vertical support plate 2. The waist belt 5 has adhesive strips 40 on the outside that are attached to the two front vertical support plates 22 (or through the side vertical support plates of the lead apron). The waist belt hooks 41 (or waist belt nose tubes) located at the waist base of the apron provide support for the front vertical support plates 22. The waist belts 5 are also secured together by adhesive strips at the ends of the two waist belts 5. Inside the lead apron, the waist belt 5 is fixed to the waist base of the back vertical support plate 2 at the back center. The waist belt 5 is a wide waist belt 5 with a central vertical support plate and a pair of symmetrical left and right vertical support plates. Alternatively, it may have a pair of symmetrical left and right vertical support plates fixed at the back center or only a central H-shaped vertical support plate. The vertical support plates are lightweight. The central vertical support plate 6 is a vertical strip (or H-shaped), and the symmetrical left and right vertical support plates 61 are H-shaped. The wide waist belt 5 is spindle-shaped with a central width greater than the widths on both sides. The lead coat 13 has a buckle connecting strap 51 between the left shoulder and the upper edge of the right outer flap on its back panel, and a buckle connecting strap 51 between the outer edge of the right outer flap and the rear part of the left inner flap to ensure a close fit.

[0042] When using, align the Velcro strap at the center of the back of the waist belt with the Velcro strap at the center of the inside of the lead apron's back, securing them together. Put on the apron and waist belt, first tightening the waist belt to the appropriate tightness. Hold the left and right front panels of the apron with both hands, shrug your shoulders slightly, first the left then the right, aligning the inner Velcro strap with the outer Velcro strap of the waist belt, securing them together. Align the front panels so that the weight of the apron is transferred through the vertical support plate to the waist belt and ultimately to the hips. With practice, you can also tighten the waist belt first, then put on the lead apron. Advantages include: cleverly utilizing the beam-column structure in architecture and the biomimetic method of human skeletal anatomy to add a "shoulder-to-waist-load mechanism" to the lead apron; using the soft connection between the vertical support plate of the lead apron and the waist belt to construct a cage-like or frame-like structure to support the lead apron and significantly reduce the stress on the shoulders and back; traditional lead aprons are worn outside the lead apron, which is close to the skin and makes it difficult to wick away sweat, often becoming soaked after a surgery, and long-term sweat stains can even cause secondary problems such as eczema and itching; the waist support is worn inside the lead apron, supported by the vertical support plate, which leaves a certain space between it and the skin to wick away moisture and sweat, reducing the problem of sweat stains and improving comfort.

[0043] Example 6, as Figure 10 As shown, the waist-bracing lead apron used in this invention to implement the lead apron load reduction method differs from the one in Embodiment 5 above in that it is a short-sleeved lead apron 14 with a vertical support plate, worn with a skirt lead apron 10 that has its own matching waist belt. The skirt lead apron 10 has symmetrical straps 101 on both sides.

[0044] Example 7, as Figure 11 As shown, the waist-supported lead apron used to implement the lead apron weight reduction method of the present invention differs from that in Embodiment Six above in that it is an extended lead apron 1 with a folded front without a lead skirt. This helps to reduce the weight burden on the support plate under tension.

[0045] In summary, the method for reducing shoulder load with lead apron and the waist-support lead apron of the present invention have the advantages of significantly reducing shoulder load, improving wearing comfort and fit, promoting perspiration, and being highly practical.
