  In the glove box shown in Patent Document 1, the housings of the work chamber 110 and the loading / unloading chamber 120 are generally formed of a stainless steel plate having a thickness of 5 mm to 10 mm in order to maintain pressure resistance and corrosion resistance. It is normal. Therefore, there is a disadvantage that the entire weight of the housing is increased and the manufacturing cost is increased. At the same time, there are many welded parts on the whole, and the pressure resistance of high vacuum is also difficult.

  In Patent Document 2, a bellows tube, that is, an expansion / contraction tube, is used for an arm portion in order to utilize its flexibility. However, there is no description or suggestion of an attempt to configure a housing with an expansion / contraction tube. It has not been.

  Further, Patent Document 3 discloses a method apparatus in which a glove box that is disassembled is housed in a bellows-shaped tent that can be freely opened and closed, and the glove box is safely disassembled in an airtight tent. However, the idea of constructing the housing of the glove box itself with a telescopic tube is not described or even suggested.

  The object of the present invention is to reduce the wall thickness by using an expansion tube, a gear-shaped tube, or an expansion / contraction tube or a gear-shaped tube having an arc cross section for the housing of the glove box and / or the loading / unloading chamber. It is an object of the present invention to provide a concavo-convex glove box that can be made compact, can increase pressure resistance, and can reduce manufacturing costs. Therefore, according to the present invention, there are few welded parts, the structure is simple, and any size is possible, and the material is composed of stainless steel as well as metals other than stainless steel, such as aluminum, inconel, steel, hastelloy, titanium, etc. An uneven glove box that can be provided can be provided.

  The present invention has been made to solve the above problems, and the first embodiment of the present invention is a glove operating port for an operator to insert a hand to work and a perspective for an operator to observe the inside. A glove box having a working chamber in which a window is arranged, the glove operating port and the see-through window are arranged in a front side housing of the working chamber, and an uneven wall having an arcuate cross section as a rear side housing of the working chamber. It is used and the surrounding surface of the said uneven | corrugated type | mold wall body is an uneven | corrugated type | mold glove box comprised by arranging many concave stripes and convex stripes by turns.

  According to a second aspect of the present invention, a loading / unloading chamber for loading and unloading a material is disposed on the side of the working chamber, the housing of the loading / unloading chamber is configured by a concavo-convex tubular body, and the circumferential surface of the concavo-convex tubular body is a large number of It is an uneven | corrugated type | mold glove box comprised by arranging a concave line and a convex line alternately.

  According to a third aspect of the present invention, the concavo-convex wall body is composed of a telescopic tube having a circular arc cross section, and the concave and convex strips are alternately arranged in the circumferential direction on the peripheral surface of the telescopic tube. It is an uneven glove box.

  According to a fourth aspect of the present invention, the concavo-convex wall body is composed of a gear-shaped tube having a circular arc cross section, and the concave and convex ridges are alternately arranged in the axial direction on the peripheral surface of the gear-shaped tube. An uneven glove box.

  According to a fifth aspect of the present invention, the concave-convex glove is configured such that the concave-convex tubular body is formed of an elastic tube, and the concave and convex ridges are alternately arranged in a circumferential direction on a peripheral surface of the elastic tube. Is a box.

  According to a sixth aspect of the present invention, the concave-convex tube body is formed of a gear-shaped tube, and the concave and convex portions are alternately arranged in the axial direction on the peripheral surface of the gear-shaped tube. Type glove box.

  According to a first aspect of the present invention, there is provided a glove box having a glove operating port for an operator to insert a hand and work, and a work chamber in which a transparent window for an operator to observe the inside is disposed, Since the glove operating port and the see-through window are arranged in the front-side housing of the work chamber, it has excellent operability similar to that of a normal glove box. In particular, the present invention is characterized in that an uneven wall having an arcuate cross section is used as the rear housing on the work chamber. Since the circumferential surface of the concavo-convex wall body is formed by alternately arranging a large number of ridges and ridges, the glove box of the present invention is referred to as a concavo-convex glove box. That is, the concavo-convex wall body is formed by alternately repeating a large number of ridges and ridges, and simply speaking, a corrugated sheet represented by a tin roof may be recalled. Moreover, the cross section is arcuate and not circular. Accordingly, the corrugated plate is rounded into an arc shape. The concave stripe and the convex stripe may be formed in the axial direction of the arc, may be formed in the circumferential direction of the arc, or may be formed in an oblique direction shifted from the axial direction and the circumferential direction. Since it is formed in a concavo-convex shape, it has higher mechanical strength than a flat plate and excellent pressure resistance, and has sufficient pressure resistance even when the inside of the work chamber is evacuated. Therefore, the thickness can be made thinner than that of the flat plate, the overall weight can be reduced, and the manufacturing cost can be reduced accordingly. When the work room of the glove box is configured with a flat plate, a thickness of 5 mm to 10 mm is usually required. However, when it is made uneven as in the present invention, a thickness of 2 mm to 3 mm is equivalent to the flat plate. The above pressure resistance can be expressed. In addition, it is possible to form a concavo-convex shape with metals such as stainless steel, aluminum, inconel, steel, hastelloy, titanium, etc., and form a concavo-convex wall using metals required for various experiments. be able to. In addition, since the concave-convex wall body having an arc-shaped cross section is used as the rear surface side housing of the working chamber, the number of welded portions between the front-side housing and the concave-convex wall body having an arc-shaped cross section is considerably reduced. That is, in the case of welding between flat plates, since four flat plates on the front, rear, upper and lower sides are welded, it is necessary to weld four joint lines. On the other hand, there are two or three joint lines between the concavo-convex wall having an arcuate cross section and the front housing, and the number of welds is clearly reduced.

  According to the 2nd form of this invention, the carrying-in / out chamber which puts in / out a raw material to the side of the said working chamber is arrange | positioned, The housing of the said carrying-in / out chamber is characterized by the point comprised with an uneven | corrugated tube. Since the circumferential surface of the concavo-convex tubular body is formed by alternately arranging a large number of ridges and ridges, the glove box of the present invention is referred to as a concavo-convex glove box as described above. Compared to the large number of welded portions in the case of a conventional cross-sectional square shape, since it is a concave-convex tube, it has a cylindrical shape, and there are very few or no welded portions for forming the housing. Moreover, since it is a tubular body in which a large number of ridges and ridges are alternately adjacent, this corresponds to a case where the corrugated sheet is round and cylindrical. As described in the first embodiment, the concavo-convex shape has higher mechanical strength than the flat plate shape and can withstand high vacuum because the pressure resistance can be enhanced. Further, since the thickness can be reduced by the amount of mechanical strength, not only the weight of the housing can be reduced, but also the manufacturing cost can be reduced corresponding to the weight reduction. In addition, it is possible to form a concavo-convex shape using metals such as stainless steel, aluminum, inconel, steel, hastelloy, titanium, etc., and using the metals required for various experiments. be able to.

  According to the third aspect of the present invention, the concavo-convex wall body is composed of a telescopic tube having an arcuate cross section, and the concave and convex strips are alternately arranged in the circumferential direction on the peripheral surface of the telescopic tube. It is possible to provide a concave-convex glove box. Since it is a telescopic tube, the concave strip and the convex strip are formed in the circumferential direction, and as a result, the telescopic tube can expand and contract in the axial direction. Moreover, since the expansion tube is cylindrical, it can be formed in a circular arc shape by cutting two locations of the expansion tube. Or you may pile up an element | base_body with an arc-shaped cross section from the beginning, and mechanically shape | mold into an expansion-contraction pipe | tube. It is also possible to bulge the straight pipe having an arcuate cross section to the expandable pipe by applying internal pressure with a special molding machine. Circumferential ridges and ridges are automatically formed in the process of forming into a telescopic tube. Since the effect of the concave stripes and the convex stripes has been described in the first embodiment, it is omitted here.

  According to the fourth aspect of the present invention, the concavo-convex wall body is constituted by a gear-shaped tube having an arc-shaped cross section, and the concave and convex ridges are alternately arranged in the axial direction on the peripheral surface of the gear-shaped tube. An uneven glove box arranged in a row can be provided. A gear-shaped tube expresses that a concave strip and a convex strip are alternately formed in the axial direction of a tube like a gear. The shape of the ridges and ridges may be anything as long as it is a valley shape or a mountain shape, and the apex may be pointed or rounded. Since the effect of the concave stripes and the convex stripes has been described in the first embodiment, it is omitted here.

  According to the fifth aspect of the present invention, the concavo-convex-type tubular body is composed of a telescopic tube, and the concavo-convex in which the concave and convex ridges are alternately arranged in the circumferential direction on the peripheral surface of the telescopic tube. A type glove box can be provided. In this form, since the said uneven | corrugated type tubular body can be comprised with a cylindrical expansion-contraction pipe as it is, it has the advantage which can be formed very easily. Since the effect of the concave stripe and the convex stripe is described in the second embodiment, it is omitted here.

    According to the sixth aspect of the present invention, the concavo-convex tube body is constituted by a gear-shaped tube, and the concave and convex ridges are alternately arranged in the axial direction on the peripheral surface of the gear-shaped tube.

A see-through window 15 made of an acrylic plate, tempered glass, or the like is disposed on the curved plate 12, and an operator works while seeing through the inside of the see-through window 15. A working chamber gas flow meter 13 is disposed on the side surface of the working chamber 10, and a working chamber pressure gauge 16 is disposed on the upper surface. The rear side housing of the working chamber 10 will be described later.

  The carry-in / out chamber 30 is constituted by a concavo-convex tube 32, and a plurality of ridges 32 a and ridges 32 b formed in the circumferential direction are alternately formed on the peripheral surface of the concavo-convex tube 32. In this 1st Embodiment, the said uneven | corrugated type tubular body 32 is comprised with the expansion-contraction pipe | tube, the protruding item | line 32a and the protruding item | line 32b are laminated | stacked on the axial direction continuously alternately, and the inside is hold | maintained airtight. Since the thickness of the expansion tube is as thin as 2 to 3 mm, it is lightweight and effective in reducing costs, and since it has a concavo-convex shape, it has extremely high pressure resistance, and has sufficient pressure resistance even in a high vacuum. In addition to the stainless steel having corrosion resistance, there is a feature that various metal materials can be formed on the expansion tube according to various experimental work. For example, various metals such as aluminum, inconel, steel, hastelloy, and titanium can be used. A carry-in / out chamber pressure gauge 34 is attached to the upper surface of the carry-in / out chamber 30, and a carry-in / out chamber gas flow meter 38 is attached to the side surface. An outer opening / closing door 36 is disposed at the outer end of the carry-in / out chamber 30, and an inner opening / closing door 37 described later is disposed at the inner end. With the inner opening / closing door 37 closed, the outer opening / closing door 36 is opened, and various materials are placed inside the carry-in / out chamber 30. Next, the outer opening / closing door 36 is closed, for example, the inside is evacuated, and the inner opening / closing door 37 is manually opened from the glove operating port 17, and the material is moved into the working chamber 10. Then, the inner opening / closing door 37 is closed.

  2 is a cross-sectional view taken along line XX of FIG. As is apparent from this cross-sectional view, the transparent window 15 is disposed on the upper surface of the transparent window projection frame 15 a, and the transparent window protrusion frame 15 a protrudes from the arcuate curved plate 12. Similarly, a glove operating port projection frame 17a projects from the vertical front plate 11. The glove operating port projection frame 17a is formed with a glove operating port 17 and a pair of gloves are provided in an airtight manner. ing. The glove operating port 17 can also be used as a door that can be opened and closed. Inside the work chamber 10, the inner opening / closing door 37 described above is disposed. The rear housing of the work chamber 10 is constituted by a large-diameter arcuate uneven wall 20, the edge 24 is welded to the curved plate 12, and the opposite edge 22 is welded to the floor plate 18. Connected. Further, a rear plate 19 is erected on the rear edge of the floor plate 18, and the central portion of the concavo-convex wall body 20 is abutted and supported by the back plate 19, and the stability of the concavo-convex wall body 20 is ensured.

  The circumferential surface of the arc-shaped concavo-convex wall body 20 is composed of a large number of circumferential ridges (substantially ring-shaped) ridges 20a and ridges 20b that are alternately continuous. The tips of the concave stripes 20a and the convex stripes 20b may be round or pointed, and the width (pitch) of the concave stripes 20a and the convex stripes 20b can be arbitrarily selected. The concavo-convex arcuate wall body has extremely high mechanical strength, and has extremely high pressure resistance as compared with a flat plate. Therefore, by configuring the rear side housing of the working chamber 10 with the concavo-convex wall body 20, the strength of the working chamber 10 can be strengthened, and the inside can be evacuated or filled with high-pressure gas. Become. Further, if the plate thickness is reduced to 2 mm to 3 mm or to the limit while maintaining the pressure resistance, the weight can be reduced and the cost can be reduced. In this 1st Embodiment, the said uneven | corrugated type | mold wall body 20 is comprised by the circular arc-shaped expansion-contraction pipe mentioned later. Since it is an arc-shaped telescopic tube, the concave strip 20a and the convex strip 20b are formed in the circumferential direction, and at the same time, there is an advantage that their pitch can be set freely. In addition to the stainless steel having corrosion resistance, there is a feature that various metal materials can be formed on the expansion tube according to various experimental work. For example, various metals such as aluminum, inconel, steel, hastelloy, and titanium can be used.

  FIG. 3 is a perspective view of the concavo-convex wall body in which the telescopic tube is formed in a cross-sectional arc shape in the first embodiment of the present invention. In this example, the concavo-convex wall body 20 is composed of an arc-shaped telescopic tube 25. After the arc-shaped expansion / contraction tube 25 is formed into a cylindrical expansion / contraction tube, the cutout portion 23 is cut and removed from the expansion / contraction tube, thereby forming the arc-shaped expansion / contraction tube 25 having the end edge 22 and the end edge 24 as both edges. . If the arc-shaped telescopic tube 25 is used as it is for the concavo-convex wall body 20 shown in FIG. 2, the ridges 25a and the recesses 25b become the ridges 20a and the recesses 20b of the concavo-convex wall body 20 as they are.

  FIG. 4 is a rear view of the first embodiment of the concave-convex glove box according to the present invention. 1 is a front view, and FIG. 4 is a rear view thereof.

It is that. In other words, the concavo-convex wall body 20 is a gear-like tube in which a corrugated plate is rolled into an arc shape, and the ridges 20 a and the ridges 20 b are formed in the same direction as the end edges 22 and 24. The tops of the ridges 20a and the ridges 20b may be round or pointed. Therefore, the telescopic tube 20 cannot be applied to the concavo-convex wall body 20.

  FIG. 7 is a perspective view of a gear-shaped tube having a circular arc cross section used in FIG. The arcuate gear-like tube 26 has both end edges 24 and 22, and a large number of ridges 26 a and recesses 26 b are alternately formed in the axial direction, that is, parallel to the both end edges 24 and 22. Therefore, the arcuate gear-like tube 26 corresponds to the concavo-convex wall body 20 having an arcuate cross section, and the ridges 26a and the recesses 26b correspond to the ridges 20a and the recesses 20b of the concavo-convex wall body 20, respectively. Since the operational effects of the ridges 26a and the concave ridges 26b are the same as the operational effects of the ridges 20a and the concave ridges 20b described above, the description thereof is omitted here.

  FIG. 8 is a rear view of the second embodiment of the concave-convex glove box according to the present invention. That is, FIG. 8 is a rear view of FIG. The rear side housing of the working chamber 10 is constituted by the concavo-convex wall body 20 having the ridges 20a and the ridges 20b. However, since the arcuate gear-like tube 26 is actually used here, The state where the strips 26a and the concave strips 26b run horizontally is depicted. Since other symbols have already been described, description of these symbols is omitted here.
