Description

Technical Field

[0001] The present invention relates to a cylindrical member, a fan with a cylindrical member, a fan, and a protective suit.

Background Art

[0002] Conventionally, protective suits have been required to have high tightness in consideration of work safety. For example, in asbestos removal work, the Ministry of Health, Labour and Welfare and the Ministry of the Environment have prepared the "Manual for Thorough Measures for Preventing Asbestos Exposure and Preventing Asbestos Scattering and Leakage in Demolition of Buildings, etc." and shown guidelines regarding asbestos removal work (Non-Patent Document 1).

[0003] However, as described in Non-Patent Document 1, from the viewpoint of preventing the adhesion of asbestos to the body surface, underwear, and work clothes worn under the protective suit, during work, it is stipulated to use an equivalent or higher product than the airtight suit for preventing floating solid dust (Type 5) of JIS T 8115. Such a protective suit is shaped to cover the whole body including the head, and the joints between the overall surface body of the protective suit and the respiratory protective device, gloves, shoe covers, etc. need to be taped, so the tightness is very high. Performing very complicated and diverse work for a long time in a high-temperature environment while wearing such a protective suit has been a great burden on workers, such as increasing the risk of heat stroke.

[0004] In order to solve such problems, Patent Document 1 discloses a configuration in which an air supply and exhaust part including a synthetic resin member is provided in a protective suit for asbestos removal work.

[0020] Figure 5 is a schematic perspective view of a first embodiment of the fan of the present invention. As shown in Figure 5, the fan F3 comprises a side 42 and a front F3f. F3f is provided with a vent for air to enter and exit.

[0021] The second connecting portion 43 is provided on the side surface 42. The second connecting portion 43 may be provided on a part of the side surface or on the entire side surface, as shown in Figure 5. The second connecting portion 43 is connected to the first connecting portion provided on the protective suit. This makes it possible to easily fix the fan to the protective suit. A detachable member is preferred for the second connecting portion 43. Examples of such detachable members include tape, snap buttons, hook-and-loop fasteners, etc. Examples of such tape include double-sided tape.

[0022] Figure 6 is a schematic perspective view of a second embodiment of the fan of the present invention. As shown in Figure 6, the fan F4 comprises a side 52 and a front F4f. F4f is provided with a vent for air to enter and exit.

[0023] The second connecting portion 53 is provided on the side surface 52. The second connecting portion 53 is a male thread and is screw-connected to the first connecting portion, which is a female thread provided on the protective suit. As shown in Figure 6, the second connecting portion 53 may be provided on a part of the side surface or on the entire side surface.

[0024] Figure 7 shows (a) a front view and (b) a rear view of the first embodiment of the protective suit of the present invention. As shown in Figure 7, the protective suit P1 according to this embodiment is equipped with filters 101 on both the left and right sides of the front torso. This makes it possible to cool the inside of the protective suit more effectively, and even if one of the fans stops, the other fan can still introduce and expel air.

[0025] Figure 8 shows (a) a front view and (b) a rear view of the protective suit according to the second embodiment of the present invention. As shown in Figure 8, the protective suit P2 according to this embodiment is equipped with filters 201 on both the left and right sides of the torso on the back.

[0026] Furthermore, protective suits P1 and P2 may be provided with one or more filters on the front and back of the torso. This makes it possible to efficiently cool the entire torso using a fan.

[0027] Figure 9 shows (a) a schematic diagram and (b) a schematic cross-sectional view along line BB of an example of a mounting portion when a fan with a cylindrical member or a fan according to the present invention is attached to protective clothing. As shown in Figure 9, the mounting portion comprises a filter 101, a fixing portion 102, an opening 103, and a first connecting portion 104. In this example, the filter 101 provided on the protective clothing P1 is fixed in close contact with the protective clothing P1 by the fixing portion 102 near the outer circumference. The fixing method is not particularly limited as long as external substances or air do not enter from the fixing portion. The first connecting portion 104 is fixed to the protective clothing P1 so as not to separate during work.

[0028] The material of the filter 101 is selected appropriately depending on the application, but for example, in the case of protective clothing for asbestos removal work, it is necessary to have a structure that prevents asbestos fibers from penetrating the inside of the protective clothing P1. As such a filter, the filter 101 can be considered to have, for example, a laminated intermediate L2 containing polyacrylonitrile fibers and polyolefin fibers, and an outer layer L1 and an inner layer L3 containing polypropylene fibers.

[0029] The basis weight of the laminated intermediate L2 is 150-250 g / m². 2 Preferably, 160-240 g / m² 2 Furthermore, the basis weight of the outer layer L1 and the inner layer L3 are 15-35 g / m². 2 Preferably, 20-30 g / m 2 That is the case.

[0030] The laminated intermediate L2 can be manufactured by known methods, such as those described in Japanese Patent Publication No. 7-256024, Japanese Patent Publication No. 2000-189732, Japanese Patent Publication No. 2002-249963, and Japanese Patent No. 7495773. Examples of polyolefin fibers include polyethylene and polypropylene. Of these, polypropylene is preferred from the viewpoint of maintaining breathability and effectively preventing the intrusion of asbestos fibers.

[0031] The outer layer L1 and the inner layer L3 can be manufactured by known methods. For example, a nonwoven fabric made of polypropylene fibers can be used, similar to masks commonly manufactured using polypropylene-containing nonwoven fabric.

[0032] Examples of methods for manufacturing the filter 11 include spunbonding and ultrasonic bonding.

[0033] The first connecting portion 104 is connected to a second connecting portion provided on a cylindrical member or fan. Preferably, the first connecting portion 104 is made of a member that is detachable from the second connecting portion. Examples of such detachable members include tape, snap buttons, hook-and-loop fasteners, etc. Examples of such tape include double-sided tape.

[0034] Figure 10 shows (a) a schematic diagram and (b) a schematic cross-sectional view along the CC line, illustrating another example of a mounting portion when a fan with a cylindrical member or a fan according to the present invention is attached to protective clothing. As shown in Figure 10, the mounting portion comprises a filter 111, a fixing portion 112, an opening 113, and a first connecting portion 114. In this example, the filter 111 provided on the protective clothing P1 is fixed in close contact with the protective clothing P1 by the fixing portion 112 near its outer circumference. The fixing method is not particularly limited as long as external substances or air do not enter through the fixing portion.

[0035] The first connection part 114 has a female thread and is connected to a second connection part, which has a male thread and is provided on a cylindrical member or fan.

[0036] Figure 11 shows a schematic side view (a) showing the exhaust state and (b) showing the blowing state when the fan with a cylindrical member according to the present invention is attached to a protective suit and the fan is in operation. As shown in Figure 11(a), when exhausting air, the fan F1 is in exhaust mode, and humid air from inside the protective suit P1 is expelled. Also, as shown in Figure 17(b), when blowing air, the fan F1 is in blowing mode, and outside air is introduced into the protective suit P1. Note that the exhaust and blowing of air by the fan F1 may be performed alternately.

[0037] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the invention is indicated by the claims rather than the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
