Description

[Technical field]

[0001] The present invention relates to a linear transmission module, and more particularly to a linear transmission module with a dustproof part. [Background technology]

[0002] Generally, in a linear transmission module, a dustproof strip made of soft material such as rubber or plastic is arranged near the slide rail to achieve sealing and dustproof effects.

[0003] The dustproof strip is generally assembled by inserting the dustproof strip along the longitudinal direction of the linear transmission module from one end cap of the slider to the other end cap, or by pressing the dustproof strip against the linear transmission module along a direction perpendicular to the longitudinal direction. Summary of the Invention [Problem to be solved by the invention]

[0004] However, a general dustproof strip has an asymmetric cross-sectional shape regardless of the assembly method, and therefore, when assembling, it is necessary to first confirm the cross-sectional shape of the dustproof strip corresponding to the assembly groove and then confirm the assembly direction, and therefore it is not possible to assemble it arbitrarily.

[0005] Also, due to the asymmetric cross-sectional shape, during manufacture, for example during injection or extrusion molding, the amount of cooling shrinkage of each part is inconsistent, making it difficult to control processing accuracy.

[0006] Furthermore, since the cross-sectional shape of the dust-proof strip is asymmetric, a mold needs to be made according to the difference in the cross-sectional shape, and repair of the mold is also relatively difficult. [Means for solving the problem]

[0007] In view of the above problems, the present invention has the following configuration.

[0008] A linear transmission module having a slider body, two end caps, and at least two dustproof parts, The slider body has a first direction defined as a longitudinal direction, a second direction defined as a width direction, and a third direction defined as a thickness direction, the first direction, the second direction, and the third direction being perpendicular to each other; the two end caps are provided at opposite ends of the slider body in the first direction, each end cap is provided with at least two assembly grooves corresponding to the second direction, each assembly groove extends along the first direction and penetrates the end cap, each assembly groove has an abutment surface, an engagement portion, and an assembly surface, the engagement portion is connected to the abutment surface and the assembly surface respectively, the abutment surface and the assembly surface are opposing surfaces, and the minimum distance between them in the fourth direction is shorter than the maximum distance in the fourth direction of the engagement portion; The at least two dustproof parts extend along the first direction, and one end of each of the dustproof parts in the first direction is assembled in the assembly groove of one of the end caps; The other end of each of the dustproof parts in the first direction is assembled into the assembly groove of the other end cap, Each of the dustproof parts includes a dustproof part body, a first contact part, and a second contact part, The first contact portion and the second contact portion are respectively located on the dustproof body and are perpendicular to opposite sides in the first direction, In addition, they protrude from the dustproof body in the fourth direction of the dustproof body and have shapes that are symmetrical to each other.

[0009] The end cap has a groove extending therethrough in the first direction. The drilling groove comprises two end cap inner surfaces in the second direction of the end cap, and the two assembly grooves are provided corresponding to the two end cap inner surfaces.

[0010] The inside of the slider body is provided with a track groove penetrating in the first direction, The track groove has two slider body inner surfaces in the second direction of the slider body and forms an opening in the third direction; The slider body further includes two external retainers, the two external retainers being disposed on an inner surface of the slider body and adjacent to the opening, respectively; Each of the outer retainers has a receiving tank extending along the first direction and corresponding to the assembly groove; When the two opposing ends of each of the dustproof parts are assembled into the assembly grooves of the two end caps, a portion of each of the dustproof parts is accommodated in the corresponding storage tank.

[0011] In addition, the number of the at least two dustproof parts is four, and the number of the at least two assembly grooves is four, The slider body further includes an internal retainer, the internal retainer facing the opening side of the track groove of the slider body, The internal retainer includes two support portions, the two support portions being arranged to correspond to the second direction, and each of the support portions being arranged to extend along the first direction; These two assembly grooves correspond to the two support parts, and the two support parts are provided on the end cap, when the two opposing ends of the two dustproof parts are respectively assembled into the assembly grooves corresponding to the support parts of the two end caps, the first contact parts of the two dustproof parts abut against the support parts, When the opposing ends of these other two dustproof parts are respectively assembled into the assembly grooves corresponding to the accommodating grooves of the two end caps, the first contact parts of these other two dustproof parts are respectively accommodated in the accommodating grooves.

[0012] The inside of the slider body is provided with a track groove penetrating in the first direction, The track groove has two slider body inner surfaces in the second direction of the slider body, and an opening is formed in the third direction, The slider body further includes an internal retainer, the internal retainer being provided on a side of the track groove of the slider body away from the opening, The inner retainer includes two support portions, the two support portions are provided to correspond to the second direction, and each of the support portions is provided to extend along the first direction; When the opposing ends of each of the dustproof parts are assembled into the assembly grooves of the two end caps, respectively, the first contact parts abut against the support parts.

[0013] Moreover, each of the support portions extends continuously from one of the end caps to the other of the end caps.

[0014] Further, each of the support portions extends from one of the end caps to the other of the end caps at a plurality of intervals.

[0017] Further, the dimension of the dustproof body in the fourth direction is equal to the minimum distance in the fourth direction between the abutment surface of the assembly groove and the assembly surface.

[0018] Further, the assembly surface of the assembly groove protrudes toward the abutment surface and abuts against the dustproof body of the dustproof part.

[0019] The two assembly grooves are provided on the outer surface of the end cap in the second direction.

[0020] Further, the hardness of the dustproof portion main body of each of the dustproof portions is harder than the hardness of the first contact portion and the second contact portion.

[0021] Furthermore, the cross sections of the first contact portion and the second contact portion are circular, elliptical, triangular, or rectangular. Effect of the Invention

[0022] As described above, according to an embodiment of the present application, a linear transmission module is provided, which has a first contact portion and a second contact portion of a corresponding shape on either side of its dustproof part. When the dustproof part is assembled into a corresponding assembly groove of the end cap, it can be fixed in the assembly groove via one of the contact portions, and the other contact portion can be abutted against an external component to seal the gap, while simultaneously achieving the effects of ease of assembly and dustproofness.

[0023] Furthermore, since the first contact portion and the second contact portion have mutually symmetrical shapes, assembly and dust prevention are possible regardless of whether the first contact portion or the second contact portion is used.

[0024] For example, when the first contact portion is used as an assembly structure, the second contact portion can be used as a dustproof structure, and when the first contact portion is used as a dustproof structure, the second contact portion can be used as an assembly structure, i.e., the first contact portion or the second contact portion can have both an assembly function and a dustproof function.

[0025] In addition, since the first contact portion and the second contact portion have symmetrical shapes, assembly by the user is easy, and the dustproof portion is also easy to manufacture.

[0026] In addition, as the usage time increases, one of the two contact parts may wear out. In this case, the dustproof part can be pulled out and reassembled using the other unworn contact part, thereby reducing the replacement rate of the dustproof part and achieving environmental protection and waste reduction.

[0028] An embodiment of the present invention will be described with reference to Figs. 1 to 4. Fig. 1 is a perspective view of a linear transmission module according to a first embodiment. Fig. 2 is a front view of the linear transmission module applied to a slide rail according to the first embodiment. Fig. 3 is an enlarged view of a main part of the linear transmission module of Fig. 2. Fig. 4 is a front view of the linear transmission module applied to a slide rail according to the first embodiment. The linear transmission module 100 includes a slider body 110, two end caps 130, and at least two dustproof parts 150.

[0029] For ease of understanding the following description, the direction extending along the longitudinal direction of the slider body 110 is referred to as a first direction Z (i.e., the Z-axis direction in FIG. 1), the direction extending along the width direction of the slider body 110 is referred to as a second direction X (i.e., the X-axis direction in FIG. 1), and the direction extending along the thickness direction of the slider body 110 is referred to as a third direction Y (i.e., the Y-axis direction in FIG. 1), and the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0030] The two end caps 130 are provided on opposite ends of the slider body 110 in the first direction Z. Since the two end caps 130 have the same structure, only one of the end caps 130 will be used for the description.

[0031] In this embodiment, the end cap 130 is described by taking four assembly grooves 131 as an example, as shown in Fig. 1. In practical applications, in order to provide the most basic dustproof effect, it is sufficient to provide only the assembly grooves 131 on both the left and right sides of the lower side of the end cap 130.

[0032] The two assembly grooves 131 located on the left and right sides of the lower side will be referred to as assembly grooves 131A and 131B, respectively (see FIG. 2). The two assembly grooves 131A and 131B are provided in correspondence with the second direction X.

[0033] The two assembly grooves 131A, 131B are located on opposite sides and have the same structure. Hereinafter, only the assembly groove 131A on the left side of FIG. 2 will be described.

[0034] 1 to 3, the assembly groove 131A penetrates the end cap 130 along the first direction Z. Also, as can be seen from Fig. 3, the assembly groove 131A has an abutment surface 1311A, an engagement portion 1312A, and an assembly surface 1313A.

[0035] The engagement portion 1312A is connected to the contact surface 1311A and the assembly surface 1313A, respectively, and the contact surface 1311A and the assembly surface 1313A are opposing surfaces.

[0036] As shown in FIG. 3, the minimum distance in the fourth direction D between the contact surface 1311A and the assembly surface 1313A is shorter than the maximum distance in the fourth direction D of the engagement portion 1312A.

[0037] This is advantageous when assembling the dustproof section 150, which will be described later, and the details of the assembly structure will be described later. In this embodiment, the fourth direction D is a direction perpendicular to the contact surface 1311A.

[0038] 1 to 3. In this embodiment, one dustproof portion 150 is assembled into each of the four assembly grooves 131, so that a total of four dustproof portions 150 are provided.

[0039] As described above, when only the two lower assembly grooves 131A, 131B are provided, only two dustproof parts 150 provided in the two corresponding assembly grooves 131A, 131B are required.

[0040] Here, the two dustproof parts 150 provided in the two assembly grooves 131A and 131B will be described.

[0041] The two dustproof parts 150A, 150B extend along the first direction Z. Since the two dustproof parts 150A, 150B have the same structure, one of them, the dustproof part 150A, will be described below.

[0042] One end of the dustproof part 150A in the first direction Z is assembled into the assembly groove 131A of the end cap 130, and the other end of the dustproof part 150A in the first direction Z is assembled into the assembly groove 131A of the other end cap 130.

[0043] Regarding a method of assembling the dustproof part 150, for example, the dustproof part 150A can be inserted along the first direction Z from the end cap 130 at one end of the slider body 110 to the end cap 130 at the other end, and both ends of the dustproof part 150A in the first direction Z are respectively accommodated in the assembly grooves 131A of the two end caps 130.

[0044] It is also possible to grasp both ends of the dustproof part 150A in the first direction Z and push the dustproof part 150A toward the two assembly grooves 131A along a direction perpendicular to the first direction Z, thereby fitting both ends of the dustproof part 150A into the two assembly grooves 131A.

[0045] 1 to 3, the dustproof part 150A has a dustproof part main body 151A, a first contact part 152A, and a second contact part 153A. The first contact part 152A and the second contact part 153A are located on both sides of the dustproof part main body 151A that are perpendicular to the first direction Z, and each protrudes from the dustproof part main body 151A in the fourth direction D of the dustproof part main body 151A and has a symmetrical shape.

[0046] In this manner, when the first contact portion 152A is assembled into the assembly groove 131A, the second contact portion 153A protrudes from the assembly groove 131A and abuts against an external component (e.g., the slide rail 500 shown in FIG. 2), thereby preventing dust or impurities from entering through the gap between the slider body 110 and the slide rail 500, or between the end cap 130 and the slide rail 500, and affecting the operation of the slider body 110 on the slide rail 500.

[0047] In addition, when the linear transmission module 100 moves along the slide rail 500, the second contact portion 153A continues to abut tightly against the slide rail 500, continuously closing the gap to isolate the internal space from the external space, and providing a dustproof effect.

[0048] Further, the dustproof portion 150A of the linear transmission module 100 is formed with a first contact portion 152A and a second contact portion 153A that are symmetrical to each other.

[0049] A user can use any contact portion to assemble the dustproof parts 150A and 150B into the assembly grooves 131A and 131B of the two end caps 130. When the dustproof parts 150A and 150B are assembled into the corresponding assembly grooves 131A and 131B of the two end caps 130, the dustproof parts 150A and 150B are fixed into the assembly grooves 131A and 131B through one of the contact portions.

[0050] In this way, the dustproof portion 150A has both an assembly effect and a dustproof effect. The first contact portion 152A is attached, and the second contact portion 153A contacts an external component to close the gap.

[0051] Furthermore, when assembling using the second contact portion 153A, the first contact portion 152A can also come into contact with an external component to fill in any gaps.

[0052] That is, each structure of the first contact portion 152A and the second contact portion 153A can be used as a dustproof structure or as an assembly structure.

[0053] Furthermore, the symmetrical first contact portion 152A and second contact portion 153A of dustproof portion 150A allows the user to assemble more conveniently and does not need to be particularly conscious of the assembly direction during assembly, which not only speeds up the assembly work and reduces the possibility of errors, but also makes it easier to manufacture dustproof portions 150A and 150B.

[0054] In addition, as the usage time increases, either the first contact portion 152A or the second contact portion 153A may become worn. In this case, the dustproof portion 150A can be pulled out and reassembled using the other unworn contact portion, thereby reducing the replacement rate of the dustproof portion 150A, thereby providing the effects of protecting the environment and reducing waste.

[0055] In this embodiment, the hardness of the dustproof part main body 151A is greater than the hardness of the first contact part 152A and the second contact part 153A.

[0056] For example, the dustproof body 151A is made of a metal or a high molecular weight polymer, and the first contact portion 152A and the second contact portion 153A are made of a high molecular weight polymer, for example.

[0057] In this embodiment, the high molecular weight polymer is, for example, plastic or rubber, and enhances the structural strength while maintaining the effect of making the first contact portion 152A and the second contact portion 153A easily deformable.

[0058] As a result, when the first contact portion 152A or the second contact portion 153A comes into contact with the slide rail 500, the deformation effect due to the flexibility allows the first contact portion 152A or the second contact portion 153A to come into close contact with the slide rail 500, thereby closing the gap.

[0059] For the assembly of the dustproof part 150A, please refer to Figures 1 to 3. In this embodiment, the assembly of the first contact part 152A will be described as an example. Similarly, since the two end caps 130 have the same structure, the end cap 130 at one end is taken as an example, and the end cap 130 at the other end will not be described again.

[0060] When the dustproof part 150A penetrates along the first direction Z and is accommodated in the assembly groove 131A, or is pushed into the assembly groove 131A from the opening between the abutment surface 1311A and the assembly surface 1313A, and both ends of the dustproof part 150A in the first direction Z are respectively assembled into the assembly grooves 131A of the two end caps 130, the first contact portion 152A is accommodated in the engagement portion 1312A, the dustproof part main body 151A abuts against the abutment surface 1311A, and the second contact portion 153A is exposed from the assembly groove 131A.

[0061] As shown in FIG. 3, the minimum distance in the fourth direction D between the abutment surface 1311A and the assembly surface 1313A is shorter than the maximum distance in the fourth direction D of the engagement portion 1312A. Therefore, when the size of the first contact portion 152A is wider than the minimum distance in the fourth direction D between the abutment surface 1311A and the assembly surface 1313A but shorter than the maximum distance of the engagement portion 1312A in the fourth direction D, the first contact portion 152A does not receive a force in the appropriate direction and is blocked by the abutment surface 1311A and the assembly surface 1313A but cannot penetrate, thereby preventing the first contact portion 152A from falling off the engagement portion 1312A.

[0062] Furthermore, the second contact portion 153A exposed in the assembly groove 131A continues to abut against the slide rail 500, and the gap between the slide rail 500 and the linear transmission module 100 is filled.

[0063] In addition, in this embodiment, the dimension of the dustproof main body 151A in the fourth direction D is shorter than the minimum distance between the abutment surface 1311A and the assembly surface 1313A in the fourth direction D, and when the second contact portion 153A presses the slide rail 500, the second contact portion 153A can deform or move toward the assembly surface 1313A in Figure 3.

[0064] This ensures space for the second contact portion 153A to move, and if the tolerances are too large during the manufacturing of the dustproof portion 150A, the second contact portion 153A and the slide rail 500 will be too tightly attached to each other, increasing the relative sliding resistance between the two and thus affecting the operation of the linear transmission module 100.

[0065] 1 and 2 again. In this embodiment, the inside of the end cap 130 has a perforated groove 132 penetrating in the first direction Z, and the perforated groove 132 has two end cap inner surfaces 133A, 133B in the second direction X of the end cap 130. The inner surfaces 133A, 133B of the two end caps are surfaces facing each other, and two assembly grooves 131A, 131B are provided to correspond to the two end cap inner surfaces 133A, 133B.

[0066] 1 and 4. In this embodiment, the slider body 110 has a track groove 111 penetrating therein in a first direction Z. The track groove 111 has two slider body inner surfaces 112A, 112B in the second direction X of the slider body 110, and an opening 113 is formed in the third direction Y.

[0067] The slider body 110 further comprises two external retainers 114A, 114B disposed on the slider body inner surfaces 112A, 112B, respectively, adjacent the opening 113.

[0068] Each of the outer holders 114A, 114B has an accommodating groove 1141A, 1141B penetrating along the first direction Z, and the accommodating groove 1141A, 1141B corresponds to the assembly groove 131A, 131B.

[0069] As can be seen from FIGS. 1 and 4, the receiving grooves 1141A and 1141B are located in the outer retainers 114A and 114B, respectively, and the outer retainers 114A and 114B face the outer surface of the track groove 111.

[0070] In this embodiment, the two external holders 114A and 114B have the same structure, so the following description will be given using only one of them, the external holder 114A.

[0071] When both ends of the dustproof part 150A in the first direction Z are respectively assembled into the assembly grooves 131A of the two end caps 130, the first contact part 152A in the middle of the dustproof part 150A in the first direction Z abuts into the corresponding accommodating groove 1141A.

[0072] In this way, additional support is provided to the dustproof portion 150A via the external retainer 114A, preventing the middle section of the dustproof portion 150A from sagging due to gravity and affecting contact with the slide rail 500 and the sliding between the slider body 110 and the slide rail 500.

[0073] In this embodiment, the dustproof part 150A is assembled in an assembly groove 131A adjacent to the opening 113, and the dustproof part 150B is assembled in an assembly groove 131B adjacent to the opening 113.

[0074] This can prevent dust or foreign matter from entering the slide rail 500, but is not limited to this.

[0075] As described above, in this embodiment, there are four dustproof parts 150. Below, the dustproof parts 150A, 150B, 150C, and 150D will be described respectively. There are also four assembly grooves 131 of the end cap 130 correspondingly, and below, the assembly grooves 131A, 131B, 131C, and 131D will be described respectively.

[0076] A method for assembling the dustproof parts 150A, 150B and the assembly grooves 131A, 131B will not be described again.

[0077] In this embodiment, as can be seen from FIG. 2, the assembly grooves 131C and 131D are located at one end farther from the opening 113 than the assembly grooves 131A and 131B.

[0078] As can be seen from FIGS. 1 and 4, the slider body 110 further includes an internal retainer 115, which is provided on the opposing side of the opening 113 in the track groove 111 of the slider body 110.

[0079] The internal cage 115 has two supports 1151, 1152 arranged corresponding to the second direction X, and each of the supports 1151, 1152 extends along the first direction Z.

[0080] The two assembly grooves 131C, 131D are provided corresponding to the two support parts 1151, 1152, and when the opposing ends of the dustproof part 150C in the first direction Z are respectively assembled into the assembly grooves 131C of the corresponding support parts 1151 of the two end caps 130, the first abutment part 152C of the dustproof part 150C abuts against the support part 1151.

[0081] When both opposing ends of the dustproof part 150D in the first direction Z are assembled into the assembly grooves 131D of the corresponding supports 1152 of the two end caps 130, the first abutment parts 152D of the dustproof part 150D abut against the supports 1152.

[0082] In this way, by providing dustproof portions 150C, 150D on the opposing inside sides of opening 113, the dustproof effect can be further enhanced, and by further supporting dustproof portions 150C, 150D via internal retainer 115, it is possible to prevent the middle sections of dustproof portions 150C, 150D from bending due to gravity, which would affect contact with slide rail 500 and the sliding between slider body 110 and slide rail 500.

[0083] In this embodiment, two dustproof parts 150A and 150B are provided adjacent to the opening 113, and two dustproof parts 150C and 150D are provided on the inside relatively far from the opening 113.

[0084] In other embodiments, the two dust prevention sections 150A and 150B may be provided only near the opening 113, or the two dust prevention sections 150C and 150D may be provided only on the inside relatively far from the opening 113.

[0085] Next, a description will be given with reference to Fig. 5. Here, Fig. 5 is a bottom view of the linear transmission module according to the first embodiment.

[0086] As shown in FIG. 5, the support portions 1151 and 1152 extend from one end cap 130 to the other end cap 130 with a plurality of intervals d therebetween, but the present invention is not limited to this.

[0087] In other embodiments, the supports 1151 , 1152 extend continuously from one of the end caps 130 to the other end cap 130 .

[0088] In another embodiment, the support portion 1152 may be provided only at the middle portion in the first direction Z to prevent the middle portions of the dustproof portions 150C and 150D from sagging due to gravity.

[0089] The assembly groove 131 and the dustproof part 150 may have other embodiments. In Fig. 3, the dimension of the dustproof part main body 151A in the fourth direction D is shown to be shorter than the minimum distance in the fourth direction D between the abutment surface 1311A of the assembly groove 131A and the assembly surface 1313A, but is not limited thereto.

[0090] Next, a description will be given with reference to Fig. 6. Here, Fig. 6 is a schematic diagram of an assembly groove of the linear transmission module according to the second embodiment.

[0091] In the second embodiment, the dimension of the dustproof main body 151A in the fourth direction D (the thickness dimension of the dustproof main body 151A) is substantially equal to the minimum distance in the fourth direction D between the abutment surface 1311A of the assembly groove 131A and the assembly surface 1313A.

[0092] As a result, one side of the dustproof part main body 151A abuts against the abutment surface 1311A, and the assembly surface 1313A abuts against the other side of the dustproof part main body 151A. With this configuration, the dustproof part 150A can be more firmly clamped in the assembly groove 131A and assembled.

[0093] In addition, while FIG. 3 shows the first contact portion 152A and the second contact portion 153A having a substantially elliptical cross-sectional shape, the present invention is not limited to this.

[0094] Description will be given with reference to Figures 7A and 7B, where Figure 7A is a schematic diagram of a dustproof part of a linear transmission module according to a third embodiment, and Figure 7B is a schematic diagram of a dustproof part of a linear transmission module according to a fourth embodiment.

[0095] In the third embodiment, the cross sections of the first contact portion 152A and the second contact portion 153A may be triangular as shown in FIG. 7A.

[0096] Alternatively, in the fourth embodiment, the cross sections of the first contact portion 152A and the second contact portion 153A may be circular or other shapes as shown in FIG. 7B.

[0097] In other embodiments, it is sufficient that the first contact portion 152A and the second contact portion 153A have a symmetrical shape, and they may have any shape, such as a rectangle.

[0098] The following description will be given with reference to Fig. 8 to Fig. 10. Fig. 8 is a front view of a linear transmission module applied to a slide rail according to a fifth embodiment. Fig. 9 is an enlarged view of a main part of the linear transmission module of Fig. 8. Fig. 10 is a schematic diagram of an assembly groove of the linear transmission module according to a sixth embodiment.

[0099] In the fifth embodiment, the linear transmission module 200 can also be applied to a slide rail 600 of a monorail robot (not shown). In this embodiment, as shown in FIG. 8, the slide rail 600 of the monorail robot is, for example, a slide rail 600 having a U-shaped cross section.

[0100] The linear transmission module 200 is slidably disposed in a recessed position of the U-shaped slide rail 600. In the fifth embodiment, a description of the same configuration as in the first embodiment will be omitted.

[0101] 8 and 9, in this embodiment, the slide rail 600 is U-shaped, and therefore the opening faces upward. The linear transmission module 200 is also assembled from above, and slides in a recessed position in the middle of the slide rail 600. Therefore, when dust falls from above, it is likely to enter through the left and right gaps where the slide rail 600 and the linear transmission module 200 come into contact with each other.

[0102] For this reason, two assembly grooves 231A, 231B are provided on the outer surface of the end cap 230 in the second direction X, and both ends of each dustproof part 250A, 250B are assembled into the two assembly grooves 231A, 231B of the two end caps 230 along the first direction Z. This closes the gap between the linear transmission module 200 and the slide rail 600, preventing the intrusion of dust or foreign matter from above.

[0103] As shown in Fig. 9, the assembly groove 231A has a groove formed so that the opening side is narrowed so that the dustproof part 250A can be assembled more firmly, but is not limited to this. Also, as shown in Fig. 10, in the sixth embodiment, the assembly groove 231A may be a groove whose inner surface extends flatly all over. [Explanation of symbols]
