Embodiment for Carrying Out the Invention

[0011] [Embodiment] Hereinafter, the machine tool 100, the leveling device 200, and the support devices 300 and 400 according to exemplary embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and the description will not be repeated.

[0012] [Definition of Directions] In the embodiment, for ease of understanding, in some of the drawings, a first direction Z, a second direction X, and a third direction Y that intersect each other are appropriately described. In this specification, the term "intersect" includes that lines, planes, or lines and planes intersect at right angles to each other and intersect at non-right angles within a slight difference range. The slight difference is a concept including, for example, tolerance and error.

[0013] One side and the other side of the first direction Z are described as the first direction one side Z1 and the first direction other side Z2, respectively. One side and the other side of the second direction X are described as the second direction one side X1 and the second direction other side X2, respectively. One side and the other side of the third direction Y are described as the third direction one side Y1 and the third direction other side Y2, respectively.

[0014] In the embodiment, the "vertical direction" is the first direction Z, which is the vertical direction when the machine tool 100 is installed on the installation surface S01 (see FIG. 1) in the posture generally used for the machine tool 100 (hereinafter referred to as the "usage posture"). The installation surface S01 is a flat surface, such as the floor surface of a factory. The "upward direction" is one side Z1 of the first direction. The "downward direction" is the other side Z2 of the first direction. Hereinafter, there may be cases where the upward direction Z1 and the downward direction Z2 are described.

[0015] Hereinafter, unless otherwise specified, the term "machine tool 100" may mean the machine tool 100 in the usage posture.

[0016] In the embodiment, the "front-rear direction" of the machine tool 100 is the second direction X. The "front direction" is one side X1 of the second direction. The "rear direction" is the other side X2 of the second direction. Hereinafter, there may be cases where the front direction X1 and the rear direction X2 are described.

[0017] The "left-right direction" is defined from the machine tool 100 toward the front direction. In the embodiment, the "left-right direction" is the third direction Y. The "left direction" is one side Y1 of the third direction. The "right direction" is the other side Y2 of the third direction. Hereinafter, there may be cases where the left direction Y1 and the right direction Y2 are described.

[0018] Also, in the embodiment, the "surface direction" is the direction along the installation surface S01, and is also the direction along the second direction X or the third direction Y. "Along" may be parallel to the installation surface S01 or may be inclined with respect to the installation surface S01 within a minute difference range.

[0019] [Machine tool 100] As shown in FIG. 1, the machine tool 100 is a machine that removes unnecessary parts from a workpiece, for example, by cutting or grinding, and forms it into a required shape. Examples of this type of machine tool 100 include a lathe, a milling machine, or a machining center.

[0020] The machine tool 100 includes, for example, a bed 1 made of cast iron. The bed 1 is one of the main components of the machine tool 100 and is the base that constitutes the machine tool 100. In addition to the bed 1, the machine tool 100 is composed of various components. However, these components are not the main parts of this embodiment. Therefore, details and illustrations of the components other than the bed 1 are omitted.

[0021] Specifically, the bed 1 has a bottom surface 11, a front surface 12, a left side surface 13, and a right side surface 14. The bottom surface 11 faces the installation surface S01 when the machine tool 100 is in the use posture. The front surface 12 is the surface of the bed 1 facing the forward direction X1 and intersects the bottom surface 11. The left side surface 13 and the right side surface 14 are the surfaces of the bed 1 facing the left direction Y1 and the right direction Y2, respectively. The left side surface 13 intersects each of the bottom surface 11 and the front surface 12. The right side surface 14 intersects each of the bottom surface 11 and the front surface 12 and is farther from the left side surface 13 in the right direction Y2.

[0022] As shown in FIGS. 1 and 2, a recess 121 that recesses toward the rear direction X2 is formed in the front surface 12. The recess 121 has an opening that opens toward the forward direction X1. Specifically, the recess 121 has a surface 122 (see FIG. 2) that faces the upward direction Z1. The surface 122 is a flat surface that extends from a predetermined position on the front surface 12 toward the rear direction X2. The surface 122 extends in each of the front-rear direction X and the left-right direction Y. That is, the surface 122 is parallel to the bottom surface 11. In the embodiment, the term "parallel" includes that lines, surfaces, or lines and surfaces do not intersect even if extended, and that they are non-parallel within a minute difference range.

[0023] As shown in FIGS. 1 and 3, a recess 131 that recesses toward the right direction Y2 is formed in the left side surface 13. The recess 131 has an opening that opens toward the left direction Y1. Specifically, the recess 131 has an upper surface 132 that faces the upward direction Z1. The upper surface 132 is a flat surface that extends from a predetermined position on the left side surface 13 toward the right direction Y2. The upper surface 132 extends in each of the front-rear direction X and the left-right direction Y. That is, the upper surface 132 is parallel to the bottom surface 11.

[0024] On the left side surface 13, a convex portion 133 is further formed. The convex portion 133 protrudes in the left direction Y1 with respect to the left side surface 13. The convex portion 133 has an outer shape generally like a rectangular parallelepiped. The convex portion 133 generally has an upper surface 134, a lower surface 135, a front surface 136, a rear surface 137, and a left surface 138.

[0025] The upper surface 134 faces in the upward direction Z1 and is flush with the upper surface 132. The term "flush" means a state where a plurality of flat surfaces are parallel without steps.

[0026] The lower surface 135 is located in the downward direction Z2 with respect to the upper surface 134 and is a surface parallel to the upper surface 134.

[0027] The front surface 136 and the rear surface 137 are parallel to each other in the front-rear direction X. Each of the front surface 136 and the rear surface 137 is a flat surface extending in the up-down direction Z and the left-right direction Y. The front surface 136 faces in the forward direction X1. The rear surface 137 faces in the rearward direction X2.

[0028] The left surface 138 is located in the left direction Y1 with respect to the left side surface 13 and is a surface parallel to the left side surface 13. The left surface 138 intersects the upper surface 134, the lower surface 135, the front surface 136, and the rear surface 137.

[0029] As shown in FIGS. 1 and 4, on the right side surface 14, a concave portion 141 that is recessed in the left direction Y1 is formed. The concave portion 141 has an opening that is open in the right direction Y2. Specifically, the concave portion 141 has an upper surface 142 that faces in the upward direction Z1. The upper surface 142 is a flat surface that extends in the left direction Y1 from a predetermined position on the right side surface 14. The upper surface 142 extends in each of the front-rear direction X and the left-right direction Y. In the embodiment, the upper surface 142 has a substantially symmetric shape in the left-right direction Y with respect to the upper surface 132 (see FIG. 3).

[0030] On the right side surface 14, a convex portion 143 is further formed. The convex portion 143 protrudes in the right direction Y2 from the right side surface 14. The convex portion 143 has an outer shape generally like a rectangular parallelepiped. The convex portion 143 has a symmetrical shape with the convex portion 133 in the left - right direction Y, and has an upper surface 144, a lower surface 145, a front surface 146, a rear surface 147, and a right surface 148.

[0031] As shown in FIGS. 2 to 4, the bed 1 further has plate - like portions 15, 16, 17. Each of the plate - like portions 15, 16, 17 is a portion that extends in the surface - along direction and is a portion where female screw portions 151, 161, 171 are formed. Specifically, the plate - like portion 15 is a portion between the bottom surface 11 and the surface 122 in the bed 1 (see FIG. 2). The plate - like portion 16 is a portion between the bottom surface 11 and the lower surface 135 and the upper surfaces 132, 134 in the bed 1 (see FIG. 3). The plate - like portion 17 is a portion between the bottom surface 11 and the lower surface 145 and the upper surfaces 142, 144 in the bed 1 (see FIG. 4).

[0032] The female screw portions 151, 161, 171 each have female threads on the peripheral surface of a hole that penetrates the plate - like portions 15, 16, 17 in the vertical direction Z.

[0033] As shown in FIGS. 1 and 5, in order to support the machine tool 100 on the installation surface S01, a pedestal 18 is used. The pedestal 18 is on the installation surface S01 and is located in the downward Z2 direction of the plate - like portion 15 (more specifically, the female screw portion 151 shown in FIG. 2).

[0034] [Leveling device 200] As shown in FIG. 1, the leveling device 200 adjusts the position of the machine tool 100 in the vertical direction Z. The leveling device 200 supports a part of the machine tool 100 from the upward Z1 and downward Z2 directions. In the embodiment, a part of the machine tool 100 is the plate - like portions 16, 17 (see FIGS. 3 and 4).

[0035] In the embodiment, there are two leveling devices 200. In the embodiment, the two leveling devices 200 have the same specifications. Note that the two leveling devices 200 may have different specifications from each other.

[0036] As shown in FIG. 6, the leveling device 200 is a leveling foot in the embodiment, and includes a pedestal 21, a leveling bolt 22, and a nut 23.

[0037] The pedestal 21 is on the installation surface S01 and is located in the downward Z2 direction of the female screw portion 161 (see FIG. 3) of the plate-like portion 16.

[0038] The leveling bolt 22 has a male thread on its circumferential surface. The leveling bolt 22 is screwed into the female thread of the female screw portion 161. That is, the leveling bolt 22 is assembled to the female screw portion 161. The end portion of the leveling bolt 22 on the downward Z2 side protrudes downward Z2 from the plate-like portion 16 and contacts the pedestal 21 from the upward Z1 direction. The end portion of the leveling bolt 22 on the upward Z1 side protrudes upward Z1 from the plate-like portion 16. That is, the leveling bolt 22 protrudes upward Z1 from the plate-like portion 16.

[0039] The nut 23 is rotated by an operator in a state of being screwed onto the end portion of the leveling bolt 22 on the upward Z1 side. As a result, the nut 23 moves either in the upward Z1 or downward Z2 direction. Thereby, the position of the machine tool 100 in the vertical direction Z is adjusted.

[0040] The other of the two leveling devices 200 is different in that it is assembled to the female screw portion 171 (see FIG. 4) as compared with one of the leveling devices 200. Therefore, a detailed description of the other of the leveling devices 200 is omitted. In the present embodiment, the position of the machine tool 100 in the vertical direction Z is adjusted by the pedestal 2 and the two leveling devices 200. Note that there may be three or more leveling devices.

[0041] [Support devices 300, 400] In FIG. 1, the support devices 300, 400 support on the installation surface S01 of the machine tool 100.

[0042] [Support device 300] As shown in FIG. 5, the support device 300 includes an anchor bolt 31, a base plate 32, a washer 33, a nut 34, and an anchor fixing adjuster bolt (hereinafter, also simply referred to as "adjuster bolt") 35.

[0043] The anchor bolt 31 is embedded in the concrete forming the installation surface S01 and protrudes upward in the Z1 direction from the installation surface S01. The anchor bolt 31 extends in the upward Z1 direction at a position slightly forward in the X1 direction from the plate-like portion 15 and the concave portion 121. The anchor bolt 31 has a male thread on its circumferential surface.

[0044] The base plate 32 is generally in the shape of a rectangular parallelepiped plate. Holes 321 and 322 are formed in the base plate 32. The holes 321 and 322 penetrate the base plate 32 from one of two parallel surfaces 323 and 324 to the other in the base plate 32. The holes 321 and 322 are separated in the long side direction of each of the surfaces 323 and 324.

[0045] The anchor bolt 31 is inserted into the hole 321. The end portion 312 on the upward Z1 side of the anchor bolt 31 protrudes upward in the Z1 direction from the base plate 32. The washer 33 is, for example, substantially annular and made of a metal plate, and is inserted into the anchor bolt 31 from the end portion 312 by an operator. As a result, the washer 33 contacts the base plate 32 from above in the Z1 direction. The nut 34 is rotated by the operator in a state of being screwed onto the end portion 312. As a result, the nut 34 moves downward in the Z2 direction and contacts the base plate 32 from above in the Z1 direction via the washer 33.

[0046] The adjuster bolt 35 has a pedestal 351, a bolt 352, and a nut 353. The pedestal 351 is on the installation surface S01 and is located in the forward direction X1 with respect to the anchor bolt 31. The bolt 352 has a male thread on its circumferential surface. The bolt 352 extends in the vertical direction Z on the pedestal 351. The nut 353 is rotated by an operator in a state where it is screwed onto the upper end portion of the bolt 352 on the upper direction Z1 side. As a result, the nut 353 moves in the lower direction Z2. The portion of the bolt 352 on the upper direction Z1 side of the nut 353 is inserted into the hole 322 of the base plate 32. By the pedestal 2 and the support device 300, the machine tool 100 is positioned in the vertical direction Z and fixed to the installation surface S01.

[0047] [Support device 400] As shown in FIGS. 7 to 9, the support device 400 includes a first portion 41, a second portion 42, and an anchor bolt 43. The first portion 41 supports the machine tool 100 (see FIG. 7) in the surface direction which is the direction along the installation surface S01. The second portion 42 supports the machine tool 100 in the vertical direction Z. The anchor bolt 43 fastens the first portion 41 and the second portion 42 to the installation surface S01. Thereby, the support device 400 can fix the machine tool 100 with a simpler configuration than in the case of using individual fixtures in a plurality of directions (i.e., the vertical direction Z and the surface direction).

[0048] More specifically, since the anchor bolt 43 fastens the first portion 41 and the second portion 42 to the installation surface S01, the machine tool 100 can be fixed in a plurality of directions with a simple configuration (i.e., the first portion 41, the second portion 42, and the anchor bolt 43). In addition, the machine tool 100 can be fixed in a space-saving manner compared to the case of using individual fixtures in a plurality of directions (i.e., the vertical direction Z and the surface direction). Note that either one of the front-rear direction X and the left-right direction Y is an example of the "surface direction" of the present disclosure.

[0049] The first part 41 further supports the machine tool 100 along another surface direction that intersects the installation surface S01 and is along the surface direction. Thereby, the machine tool 100 can be fixed in the vertical direction Z, the surface direction, and another surface direction with a simpler configuration than in the case of using individual mounting tools in a plurality of directions. Note that either one and the other of the front-rear direction X and the left-right direction Y are examples of the "surface direction" and the "other surface direction" of the present disclosure.

[0050] The first part 41 and the second part 42 are separate members from each other. However, the present invention is not limited to this, and the first part 41 and the second part 42 may be the same member. The anchor bolt 43 has nuts 431 and 432 (see FIG. 8). The nut 431 is an example of the "first nut" in the present disclosure. The nut 432 is an example of the "second nut" in the present disclosure. The nut 431 is a nut for fastening the first part 41 to the installation surface S01. The nut 432 is a nut for fastening the second part 42 to the installation surface S01. Thereby, the machine tool 100 can be positioned on the installation surface S01 with one anchor bolt 43.

[0051] The first part 41 has an upper surface 411 facing the upward direction Z1. The upper surface 411 has a recess 412 that is recessed in the downward direction Z2 between both ends in the surface direction. The nut 431 is provided in the recess 412. Since the nut 431 is provided in the recess 412, the size of the support device 400 in the vertical direction Z can be suppressed.

[0052] The first part 41 has a base portion 413, a protruding portion 414, and at least two bolts 415. The base portion 413 extends in the surface direction. The protruding portions 414 protrude from positions spaced apart from each other in the surface direction of the base portion 413 in another surface direction. At least two bolts 415 are provided on the protruding portion 414 and support the machine tool 100 from one side and the other side in the surface direction. At least two bolts 415 are an example of the "two first members" in the present disclosure. The machine tool 100 can be easily supported in the surface direction as compared with the case where it is not supported by the bolts 415. Note that the first member may be a member other than a bolt.

[0053] In the embodiment, the base portion 413 extends in the front-rear direction X as an example of the along-surface direction. The protruding portion 414 protrudes in the left-right direction Y as an example of another along-surface direction. At least two bolts 415 support the machine tool 100 from the forward direction X1 and the rearward direction X2 as examples of one side and the other side of the along-surface direction, respectively.

[0054] The first portion 41 further has at least one bolt 416 provided on the base portion 413. At least one bolt 416 supports the machine tool 100 from one side or the other side of another along-surface direction. At least one bolt 416 is an example of the "at least one second member" in the present disclosure. Thereby, the machine tool 100 can be easily supported in another along-surface direction as compared with the case where it is not supported by the bolt 416. Note that the second member may be a member other than a bolt.

[0055] The second portion 42 and the leveling device 200 support a part of the machine tool 100 from the upward direction Z1 and the downward direction Z2. Thereby, the machine tool 100 is surely positioned in the vertical direction Z as compared with the case where the machine tool 100 is not supported by the second portion 42.

[0056] The second portion 42 contacts the plate-shaped portion 16 from the upward direction Z1 on both sides of the leveling bolt 22 in the along-surface direction. Thereby, the load from the second portion 42 does not bias to one side in the along-surface direction with respect to the leveling bolt 22.

[0057] Next, with reference to FIGS. 1 to 9, a more detailed configuration of the support device 400 will be described. In the embodiment, there are two support devices 400 (see FIG. 1). In the embodiment, the two support devices 400 have the same specifications as each other. Note that the two support devices 400 may have different specifications from each other.

[0058] As shown in FIGS. 7 to 9, the first portion 41, the second portion 42, and the anchor bolt 43 are made of metal.

[0059] In the first part 41, the base 413 has an outer shape of a substantially rectangular parallelepiped. However, the upper surface of the base 413 coincides with the upper surface 411 of the first part 41. Accordingly, the base 413 has a recess 412 between both ends in the front-rear direction X.

[0060] The base 413 is formed with female screw portions 417 (see FIG. 9) corresponding to the number of bolts 416. In the embodiment, the number of bolts 416 is 2. Accordingly, the number of female screw portions 417 is 2. The two female screw portions 417 are located on both sides of the recess 412 in the front-rear direction X. The two female screw portions 417 have female threads on the peripheral surface of a hole penetrating the base 413 in the left-right direction Y. The two bolts 416 are screwed into and penetrate the two female screw portions 417, and abut against the left surface 138 of the plate-like portion 16, specifically, the convex portion 133, from the left direction Y1 as an example of another surface contact direction. Thereby, the support device 400 supports the machine tool 100 in the left-right direction Y.

[0061] The base 413 is further formed with a hole 418 penetrating the first part 41 in the vertical direction Z from the recess 412.

[0062] The protruding portion 414 has an outer shape of a substantially rectangular parallelepiped. The protruding portion 414 is formed with female screw portions 419 (see FIGS. 8 and 9) corresponding to the number of bolts 415. In the embodiment, the number of bolts 415 is 2. Accordingly, the number of female screw portions 419 is 2. The two female screw portions 419 are formed in the base 413 in the front-rear direction X. The two female screw portions 419 have female threads on the peripheral surface of a hole penetrating the protruding portion 414 in the front-rear direction X. The two bolts 415 are screwed into and penetrate the two female screw portions 417, and abut against the plate-like portion 16 (specifically, the front surface 136 and the rear surface 137 of the convex portion 133) from the front direction X1 and the rear direction X2 as an example of another surface contact direction. Thereby, the support device 400 supports the machine tool 100 in the front-rear direction X.

[0063] The second part 42 is thin and plate-shaped in the vertical direction Z. In the second part 42, holes 421, 422 (see FIGS. 8 and 9) are formed. The holes 421, 422 penetrate the second part 42 from one of the two mutually parallel surfaces 423, 424 in the second part 42 to the other. The holes 421, 422 are separated from each other in the left-right direction Y.

[0064] In the first part 41, the base 413 is placed on the installation surface S01 by the operator. At this time, an anchor bolt 43 is inserted into the hole 418 of the first part 41. A washer 433 is inserted from the upper Z1-side end of the anchor bolt 43. The nut 431 is rotated by the operator while being screwed onto the upper Z1-side end of the anchor bolt 43. As a result, the nut 431 moves downward in the Z2 direction. Thereby, the first part 41 is fastened to the installation surface S01 by the anchor bolt 43 and the nut 431.

[0065] Also, the hole 421 of the second part 42 is inserted through the upper Z1-side end of the anchor bolt 43 by the operator. Here, in the second part 42, a concave portion 425 with a semi-elliptical notch is formed at the end on the right Y2 side. The concave portion 425 moves downward in the Z2 direction together with the second part 42 and contacts the plate-shaped portion 16 from above in the Z1 direction on both sides in the front-rear direction X with respect to the leveling bolt 22 (see FIG. 7). Thereafter, a washer 435 is inserted from the upper Z1-side end of the anchor bolt 43. The nut 432 is rotated by the operator while being screwed onto the upper Z1-side end of the anchor bolt 43. As a result, the nut 432 moves downward in the Z2 direction. Thereby, the second part 42 is fastened to the installation surface S01 by the anchor bolt 43 and the nut 432.

[0066] The support device 400 further has an adjuster bolt 44.

[0067] The adjuster bolt 44 has a pedestal 441, a bolt 442, and a nut 443. The pedestal 441 is on the installation surface S01 and is located in the leftward direction Y1 relative to the anchor bolt 43. The bolt 442 has a male thread on its circumferential surface. The bolt 442 extends in the vertical direction Z on the pedestal 441. The nut 443 is rotated by an operator in a state of being screwed onto the upper-end portion on the Z1 side of the bolt 442. As a result, the nut 443 moves in the downward direction Z2. The portion of the bolt 442 on the Z1 side above the nut 443 is inserted into the hole 422 of the second portion 42. By the support device 400, the machine tool 100 is positioned in the vertical direction Z, the front-rear direction X, and the left-right direction Y and fixed to the installation surface S01.

[0068] The other of the two support devices 400 is different from one of the support devices 400 in that it is mounted on the plate-shaped portion 17. Therefore, a detailed description of the other of the support devices 400 is omitted.

[0069] [Modification Example] Next, with reference to FIGS. 10 and 11, the machine tool 100 and the support device 400 according to a modification example of the embodiment will be described.

[0070] The machine tool 100 has recesses 51 and 52 instead of the convex portions 133 and 143 in the embodiment. Each of the recesses 51 and 52 is formed in the bed 1.

[0071] The recess 51 is defined by a first surface 511, a second surface 512, and a third surface 513. The first surface 511 and the second surface 512 face each other in the tangential direction. The third surface 513 extends in the vertical direction Z and the other tangential direction.

[0072] Specifically, the recess 51 is open in both the vertical direction Z and the leftward direction Y1. Also, each of the first surface 511 and the second surface 512 extends in the vertical direction Z and the left-right direction Y. The second surface 512 is located in the rearward direction X2 relative to the first surface 511 and faces the first surface 511.

[0073] The recess 52 is defined by a first surface 521, a second surface 522, and a third surface 523. The first surface 521 and the second surface 522 face each other in the along-surface direction. The third surface 523 extends in the vertical direction Z and other along-surface directions.

[0074] Specifically, the recess 52 is open in both the vertical direction Z and the left direction Y1. Also, each of the first surface 521 and the second surface 522 extends in the vertical direction Z and the left-right direction Y. The second surface 522 is located in the rear direction X2 with respect to the first surface 521 and faces the first surface 521.

[0075] In the support device 400, the first part 41 is different in that it further includes a base 61 instead of the base 413 in the embodiment. The base 61 is different from the base 413 in that at least a part of it is accommodated in the recess 51 and it does not have the protruding portion 414.

[0076] The first part 41 is further different in that it includes two bolts 62 and two bolts 63 instead of the bolts 415, 416 in the embodiment. The two bolts 62 and the two bolts 63 are an example of the "two first members" and the "at least one second member" in the present disclosure.

[0077] The two bolts 62 are provided on the base 61 and support the machine tool 100 from one side and the other side in the along-surface direction. Specifically, two nuts 64 are screwed onto the tips of the two bolts 62. The operator rotates one nut 64 with one bolt 62 and the nut 64 positioned between the base 61 and the first surface 511. The operator rotates the other nut 64 with the other bolt 62 and the nut 64 positioned between the base 61 and the second surface 512. Thereby, the two bolts 62 support the machine tool 100 from one side and the other side in the along-surface direction.

[0078] Two bolts 63 are provided on the base 61 and support the machine tool 100 from one or the other of the other surface directions in the same manner as the two bolts 416. That is, the two bolts 63 are screwed into and penetrate the two female screw portions 417 and abut against the plate-shaped portion 16 from the front direction X1 and the rear direction X2 as an example of the other surface direction. Thereby, the support device 400 supports the machine tool 100 in the front-rear direction X.

[0079] The other of the two support devices 400 is different in that it is housed in the recess 52 as compared with one of the support devices 400. Therefore, a detailed description of the other of the support devices 400 will be omitted.

[0080] Thereby, the support device 400 can fix the machine tool 100 with a simpler configuration than when using individual fixtures in a plurality of directions (that is, the vertical direction Z and the surface direction).

[0081] In addition, the drawings schematically show each component mainly for easy understanding of the present disclosure, and the thickness, length, number, interval, etc. of each illustrated component may be different from the actual ones for convenience of drawing creation. Also, the configuration of each component shown in the above embodiment is an example and is not particularly limited, and it goes without saying that various changes can be made without substantially departing from the effects of the present disclosure.
