Description

  The present invention relates to a connecting member useful for connecting a short rail member to form a long rail, and a connecting structure including the connecting member.

  In order to connect adjacent members, various connecting members are used. For example, it is known to attach a rail member using a bracket. However, since the brackets are attached at intervals in the longitudinal direction of the rail member, it is usually difficult to connect and extend adjacent rail members.

  On the other hand, in order to connect a pair of members so that rotation is possible, the connection pin as a pivot is utilized. Japanese Patent Application Laid-Open No. 8-26020 (Patent Document 1) relates to a lashing rail (long metal plate) mounting device for hooking a rope hook (metal fitting) in a vehicle such as a truck. A protrusion protruding outward and at least one of the protrusions and a protrusion protruding inward are formed adjacent to and opposed to each other in the vertical direction, and a connecting pin fitting groove is formed in the opposing portion of these protrusions. It is described that the lashing rail is attached with good workability by forming a through hole 20 and inserting connecting pins into at least both front and rear ends of the entire length of the through hole. However, such a form does not extend the rail member in the longitudinal direction by the connecting pin.

  In order to arrange a rail member that can be run by a runner or the like, a connecting member that can be attached to the upper wall is used. For example, in Japanese Unexamined Patent Application Publication No. 2013-135931 (Patent Document 2) and Japanese Unexamined Patent Application Publication No. 2013-81747 (Patent Document 3), a connecting rod (joint pin) is formed in a connecting hole (or connecting concave portion) of an adjacent rail member. Etc.), it is described that adjacent rail members can be connected and extended in the longitudinal direction. When the connecting rod-like bodies described in these documents are used, the rail members can be connected while being positioned. However, if the diameter of the connecting rod-like body is smaller than the inner diameter of the connecting hole, the adjacent rail members are displaced from each other and cannot be firmly connected even if they are easily mounted in the connecting hole. On the other hand, if the diameter of the connecting rod-like body is the same as the inner diameter of the connecting hole, it is difficult to mount it in the connecting hole.

  Furthermore, although rail members are usually stacked and stored and transported, they are long and heavy. Therefore, a large storage and transportation space is required, and the storage and transportation costs also increase.

JP-A-8-26020 ([0001] [0007], FIG. 1) JP2013-135831A ([0072], FIG. 5) JP 2013-81747 A ([0045], FIG. 4)

  Accordingly, an object of the present invention is to provide a connecting member (engaging connecting member, connecting pin) that can form a long rail by simply and reliably connecting short rail members and a connecting structure including the connecting member. is there.

  Another object of the present invention is to provide a connecting member capable of reducing storage and transportation space for rail members and storage and transportation costs, and a connecting structure including the connecting member.

  As a result of intensive studies to achieve the above-mentioned problems, the inventor has shortened the rail member, and formed engaged portions (such as concave grooves or protrusions) on both side walls of the short rail member. The first engaged portion is engaged at one end of an engagement connecting member (clamping or pinching connecting member) that can be attached to the wall, and a screw at the other end. When engaged with the second engaged portion using the advance / retreat of the member, both ends of the rail member can be connected in a sandwiched or gripped state, and the adjacent rail members can be firmly connected without being displaced; A connecting hole extending in the longitudinal direction is formed in the rail member, and connected to the central region in the longitudinal direction of the shaft portion having an outer diameter that can be inserted into the connecting hole as a connecting pin to be attached to or inserted into the connecting hole of the adjacent rail member. Forms a thick cylindrical part with an outer diameter larger than the inner diameter of the hole When using a connecting pin (connecting rod body) which is formed by crossing the peripheral surface of the thick cylindrical portion to form an intersecting groove portion, a shaft portion is attached to or inserted into the connecting hole and the like. It was found that when the convex portions between the two are pressed, the top portions of the convex portions between the intersecting groove portions are crushed, and the adjacent short rail members can be reliably and firmly connected without being displaced, thereby completing the present invention.

  That is, the engagement connecting member of the present invention is used for connecting a rail member having engaged portions to both side walls and attaching to a wall portion (upper wall such as a ceiling wall and / or side wall). . The engagement connecting member can be attached to the wall portion, and can be disposed in a connecting area (adjacent area of a predetermined length) of short rail members (a pair of short rail members) adjacent to each other. A first mounting portion (such as a groove or a ridge) that is bent or curved at one end in the width direction of the plate-shaped mounting portion and formed on one side wall of the rail member. A second engaging portion (concave) formed at the other end in the width direction of the plate-like mounting portion and formed on the other side wall of the rail member. A side wall (for example, a side wall into which a screwing member can enter) capable of being attached to an advancing / retreating member that can be engaged (and / or pinched) by advancing / retreating. ing. Such an engagement connecting member can also be referred to as a pinching or pinching connection member because the rail member can be pinched or pinched as well as being engaged with the rail member by the forward movement of the advance / retreat member. Since such an engaging connection member is disposed in a connection region of adjacent rail members, it is usually short and may be attached in a form straddling the connection region or adjacent region of the plate-like attachment portion.

  Even if the rail member of such a form is provided with a connecting hole that can be connected to each other in the longitudinal direction by a connecting pin (or connecting rod) as an engaging connecting member in order to connect adjacent short rail members. Good. The connecting pin (or connecting rod) includes a shaft portion (or a cylindrical shaft portion) having a predetermined length, and a thick cylindrical portion formed in a central region in the axial direction leaving both side portions of the shaft portion. The thick-walled cylindrical portion may be provided with a groove portion (such as a spiral groove portion) formed in parallel or intersecting with each other.

  The present invention also includes a connecting pin (or connecting rod) for connecting a plurality of short rail members having connecting holes formed in the longitudinal direction. The connecting pin (or connecting rod) includes a shaft portion (cylindrical shaft portion or the like) having a predetermined length that can be inserted into the connecting hole, and a central region in the axial direction of the shaft portion (a central region that leaves both side portions). And a thick cylindrical portion having an outer diameter larger than the inner diameter of the connecting hole, and a groove portion (for example, a groove in an oblique direction) engraved on the peripheral surface of the thick cylindrical portion in parallel or crossing each other. Etc.). In such a connecting pin (or connecting rod), the groove (or spiral groove) may be formed in a spiral shape with a depth equal to or less than the outer diameter of the shaft portion intersecting the diagonal direction. A quadrangular pyramidal protrusion may be formed adjacent to the cylindrical portion. In addition, you may form a groove | channel with the depth below the internal diameter of the said connection hole.

  The present invention relates to an engagement connecting member (a pinching or pinching connecting member) that can be disposed in a form engaged with engaged portions on both side walls of the rail member; and a connecting hole formed in the longitudinal direction of the rail member A connection set including a connection pin (or connection rod body) that can be attached to the rail, and a connection structure including the rail member, the engagement connection member, and the connection pin (or connection bar body) are also included. In this connection set and connection structure, the engagement connection member is disposed in a connection region of adjacent short rail members and is configured by the engagement connection member that can be engaged with or sandwiched with the engaged portion. Alternatively, the connecting pin (or connecting rod) may be constituted by the connecting pin (or connecting rod) that can be mounted in the connecting hole of the adjacent rail member.

  Furthermore, this invention also includes the method (or method of constructing) which connects an adjacent rail member. In this method, the engaging connecting member (clamping connecting member) is attached to the wall portion; the connecting area of the adjacent short rail members in a state where the end faces of the engaging connecting member plate-like attaching portions are abutted or opposed to each other. The first engagement portion of the rail member is engaged with the bending engagement portion of the engagement connecting member, and the advance / retreat member is engaged with the second engagement portion of the rail member. The adjacent rail members can be connected (or constructed) by attaching (or press-fitting) both side portions of the connecting pins to the connecting holes of the adjacent rail members.

  In the present specification, the engaging connecting member (or the sandwiching connecting member) and the connecting pin function as connecting means, respectively, and may be simply referred to as “connecting member”. Moreover, a connection pin is used not only in the elongate form but in the meaning including a rod-shaped body.

  In the present invention, since the engagement and clamping mechanism of the engagement connecting member (clamping or clamping pressure connecting member) and the engagement mechanism with advancement and retraction are used, the short rail member can be connected easily and reliably in an orderly manner. A long rail can be formed by extending the rail member. Further, since the predetermined connecting pin is used, it is possible to connect the short rail member in an orderly, surely and firmly without being displaced. Furthermore, the connection structure of a rail member can be formed easily and firmly using the said engagement connection member and a connection pin, and a rail member can be connected or constructed orderly. Furthermore, since the rail member can be stored and transported by shortening (shortening) the rail member, it can be stored and transported in a small space, and the transportation cost can be greatly reduced.

  In the example shown in FIGS. 1 to 4, the rail members 1 a and 1 b are short and are formed in a symmetrical cross-sectional shape by metal extrusion (or aluminum extrusion). That is, the short rail members 1a and 1b are formed in a plate-like upper wall 2, side walls 3a and 3b extending from both ends of the plate-like upper wall, and recessed in the longitudinal direction on the upper sides of the both side walls. U-shaped concave grooves 4a, 4b and ridges 5a, 5b formed on the upper ends of both side walls 3a, 3b by the concave grooves, and the concave grooves 4a, 4b and the ridges 5a, 5b are provided. The engaged part is formed. Further, the lower end portions of both side walls 3a and 3b are bent inward to form a running portion where the runner can run. That is, it is formed on the bent bottom walls 6a and 6b that are bent inward from the lower ends of the side walls 3a and 3b and extend at a predetermined interval, and the runner wheel that can run on the tip of the bent bottom wall. It has walls 7a and 7b and connecting holes 8a and 8b formed in the traveling wall so as to extend in the longitudinal direction. The space between the pair of running walls facing each other forms a running space for the runner, and the upper walls (upper surfaces) of the running walls 7a and 7b form a running path that can contact the wheels of the runner, The connecting holes 8a and 8b are open along the longitudinal direction toward the side walls 3a and 3b. The plate-like upper wall 2 is formed with a shallow groove-like concave portion in the longitudinal direction, and the inner wall of the plate-like upper wall 2 is countersunk, and using this countersink, a screw member 17 or the like is used. The fixing member can be attached to the upper wall.

  In order to connect such rail members 1a and 1b and attach them to a wall portion (upper wall, side wall, etc.), an engagement connecting member having a length corresponding to the connecting region (adjacent region) of the rail members 1a and 1b ( An engagement connecting member 11 having a short length is used. The engagement connecting member 11 is bent or bent into a V shape at an acute angle from one end portion in the width direction of the plate-like attachment portion, which can be attached to the wall portion, and A bent engagement portion 13 that can be engaged with the first protrusion 5a by inserting a bent tip portion into the first concave groove 4a on one side wall of the rail members 1a and 1b, and the plate-like attachment portion 12 And a side wall 14 extending from the other end in the width direction. In the longitudinal direction of the side wall portion, a plurality of screwing members (screw members) 15 are screwed so as to be able to advance and retract at predetermined intervals. A mating screw hole (female screw portion) 16 is formed. Therefore, by screwing the screwing member (screw member) 15 into the screwing hole 16 of the side wall portion 14, the second groove 4b formed on the other side wall of the rail members 1a and 1b is screwed. The joint member (screw member) 15 is moved forward to enter or fit into the second groove 4b, and the tip of the shaft portion of the screw member (screw member, screw) 15 is engaged with the second protrusion 5b. Is possible. Further, in addition to the engagement between the shaft portion of the screwing member (screw member, screw) 15 and the second protrusion 5b, the rail member 1a, 1b is clamped by the forward movement of the screwing member (screw member) 15. Clamping is possible. In the side wall 14, a peripheral portion of a screw hole (female screw portion) 16 is formed with an extruding portion 16a protruding outward, and a screw hole (female screw portion) 16 is formed in the push portion.

  In such an engagement connecting member 11, the plate-like attachment portion 12 of the engagement connecting member 11 is attached to the upper wall using a fixing member such as a screw member 17, and adjacent areas of the short rail members 1 a and 1 b adjacent to each other. With the (connection area) covered, the plate-like mounting portion 12 of the engagement connection member 11 is positioned or disposed in the adjacent area (connection area), and the rail member is placed on the bending engagement portion 13 of the engagement connection member 11. The first concave grooves 4a of 1a and 1b are inserted and engaged with the first protrusion 5a, and a screwing member (screw member) 15 is screwed from the side wall portion 14 of the engagement connecting member 11 and screwed. A short rail is formed by causing the tip (shaft) of the member (screw member) 15 to enter the second concave groove 4b and engaging the second protrusion 5b or pressing the second concave groove 4b. The adjacent area (connection area) of the members 1a and 1b is clamped (pinched) or gripped from both sides without being displaced. It can be firmly linked in the form. Further, the bending engagement portion 13 of the engagement connecting member 11 is engaged with the first protrusion 5a, and the rail members 1a and 1b are attached to the inner wall (or lower surface) of the plate-like attachment portion 12 with this engagement portion as a base point. The rail members 1a and 1b can be reliably connected in the adjacent area (connection area) by a simple method of turning and screwing the screwing member (screw member) 15 to clamp. At that time, even if the front end portion of the screwing member 15 is screwed into the screwing hole (female screw portion) 16 without protruding the front end portion of the screwing member 15 from the inner wall of the side wall portion 14, it protrudes outward. The pushing portion 16a can secure the thickness and hold the screwing member 15, and can prevent the screwing member 15 from coming off. Therefore, in a state where the tip end portion of the screwing member 15 is fixed in the screwing hole (female screw portion) 16 (temporarily fixed state that does not protrude from the inner wall of the side wall portion 14), the rail member 1a, Even if 1b is rotated to the inner wall (or lower surface) of the plate-like attachment portion 12, the side wall portion 14 does not come into contact with the tip end portion of the screwing member 15. Therefore, the rail members 1a and 1b are rotated in a temporarily fixed state in which the tip end portion of the screwing member 15 is screwed into the screwing hole 16, and the screwing member 15 is further screwed to advance the tip portion. By doing so, the rail members 1 a and 1 b can be smoothly mounted on the engagement connecting member 11.

  Further, a connecting pin 21 can be mounted or press-fitted into the connecting holes 8a and 8b. The connecting pin 21 is formed in a cylindrical shaft portion 22 having a predetermined length that can be inserted into the connecting holes 8a and 8b, and a central region in the axial direction of the cylindrical shaft portion (a central region with both side portions remaining). The thick cylindrical portion 23 is formed so that the outer diameter of the thick cylindrical portion is larger than the inner diameters of the connecting holes 8a and 8b. The circumferential surface of the thick cylindrical portion 23 is deeper than the outer diameter of the shaft portion 22 (or the connecting holes 8a, A groove portion 24 having a V-shaped cross section is engraved deeper than the inner wall of 8b to form a cross groove portion (spiral groove portion) 25. In this cross groove portion (spiral groove portion), the groove portion 24 is engraved. Thus, the quadrangular pyramid (or pyramid) projections 26 are formed adjacent to each other in a staggered manner.

  In such a connecting pin 21, the shaft portions 22 on both sides of the connecting pin 21 can be easily inserted into the connecting holes 8a and 8b of the adjacent rail members 1a and 1b, respectively, and the connecting holes 8a and 8b of the rail members 1a and 1b can be easily inserted. When the thick cylindrical portion (intersecting groove portion or spiral groove portion) 23 of the connecting pin 11 is press-fitted into 8b, the quadrangular pyramidal protrusions 26 are crushed, and the adjacent short rail members 1a and 1b are not neatly displaced. Connect closely and firmly. The press-fitting of the connecting pin 21 can be performed by a conventional method, for example, a method of hitting the end of the connecting pin 11 or the rail members 1a and 1b with a hammering member such as a hammer or a mallet.

  In the present invention, since the engaging connecting member and the connecting pin function as a connecting member or connecting means, respectively, a rail member in which engaged portions are formed on both sides; a rail in which connecting holes are formed in the longitudinal direction. Member: It can be applied to any of rail members in which engaged portions are formed on both sides and a connecting hole is formed in the longitudinal direction. The rail member does not need to have a left-right symmetric structure, and the engaged portion can be formed at an appropriate position on both side walls of the rail member, but can usually be formed at the upper part of both side walls. The engaged portion may be formed by a concave groove (or concave portion) and / or a ridge (or convex portion), and the ridge can be formed adjacent to the concave groove by forming the concave groove. Alternatively, it may be formed by projecting laterally outward on both side walls without forming a concave groove. The connecting hole can also be formed at an appropriate position of the rail member, and is not limited to the traveling wall, and may be formed in a bent bottom wall, a side wall, a plate-like upper wall, or the like. Further, the cross-sectional shape of the coupling hole is not limited to a circular shape, and may be an irregular shape (an elliptical shape, a polygonal shape, etc.) or a key groove shape. Further, the connecting hole does not need to be opened along the longitudinal direction, but in order to improve the press-fitting operability of the connecting pin, it is opened in a slit shape along the longitudinal direction, and is curved or bent adjacent to the opening. A free-end curved or bent wall may be formed. Furthermore, although one connection hole may be formed in the rail member, in a state in which it is positioned by forming a plurality of connection holes (for example, 2 to 5, preferably about 2 or 3 connection holes). Short rail members can be connected in an orderly manner.

  FIG. 5 is a schematic sectional view showing another example of the present invention. In this example, a connection structure basically similar to that in the example shown in FIG. 1 is shown except that the structure of the rail member is mainly different. That is, the short rail members 31a and 31b are formed of a hard and high-strength metal such as steel or stainless steel (such as bending of a metal steel plate) in a symmetrical cross-sectional shape. Both side walls 33a and 33b which are bent and extended from both ends of 32, concave grooves 34a and 34b and protrusions 35a and 35b which are recessed along the longitudinal direction in the upper part of both side walls, and both side walls. The lower ends of 33a and 33b are respectively provided with bent bottom walls 36a and 36b that bend inward. The distal ends of the bent bottom walls 36a and 36b are formed as curved walls that extend further upward (rise up) and are curved (or rounded) outward, and are capable of running the runner wheels 37a and 37b. And connecting holes 38a and 38b formed by the curved walls of the traveling wall.

  Even such a rail member 31 can be effectively connected by the same engaging connecting member 11 and connecting pin 21 as described above.

  Furthermore, when the long rail member formed of the metal is cut to produce the short rail members 31a and 31b, the interval between the connecting holes 38a and 38b is narrowed in the one rail member 31a along with the cutting operation. The other rail member 31b expands at the interval between the connecting holes 38a and 38b, and short rail members 31a and 31b having different intervals between the connecting holes 38a and 38b are generated. For example, with the cutting operation, a pair of short rail members 31a and 31b in which the distance between the coupling holes 38a and 38b is different by about 1 to 1.5 mm are generated. In addition, along with the cutting, a short rail member in which the shape of the coupling holes 38a and 38b is deformed may be generated. Even in the case of such rail members 31a and 31b, by attaching or press-fitting the connecting pin 21 to the connecting holes 38a and 38b, the spacing and deformation of the connecting holes 38a and 38b can be corrected, and adjacent to each other without being displaced. The short rail members 31a and 31b can be connected in an orderly manner.

  The rail member does not need to be provided with both side walls as long as it can be clamped or clamped by the engagement connecting member in the engaged state with the engagement connecting member. FIG. 6 is a schematic sectional view showing another example of the present invention.

  In this example as well, a connecting structure similar to that in the example shown in FIG. 1 is basically shown except that the structure of the rail member is mainly different. In other words, the short rail members 41a and 41b are formed in a symmetrical I-shaped cross-section by metal extrusion (or aluminum extrusion). The rail members 41a and 41b extend laterally from the plate-like support shaft portion 42 and the upper and lower end portions of the plate-like support shaft portion 42, and are extended engagement portions (projecting engagements) as engaged portions. Part) 43a, 43b, 44a, 44b, and connecting holes 45a, 45b formed in the upper and lower ends of the plate-like support shaft part 42. It should be noted that the base portions of the extending engaging portions 43a, 43b, 44a, 44b are formed thick and reinforced, and the upper extending portions are formed in order to increase the engaging strength with the engaging bent portion 53 of the engaging connecting member 51. The distal end portions of the lower walls of the projecting engaging portions 43a and 43b protrude or bulge downward, and the distal end portions of the upper walls of the lower extending engaging portions 44a and 44b project or bulge upward, respectively. A concave portion having a trapezoidal cross section is formed. In addition, you may form the running surface of the wheel of a runner with the recessed part of cross-sectional trapezoid shape.

  In the engagement connecting member 51, the engagement bent portion 53 formed at one end portion of the plate-like attachment portion 52 is in the downward direction at the distal end portions of the lower walls of the upper extension engagement portions 43a and 43b. Is formed in a U-shaped cross section or trapezoidal shape that can accommodate or mount a protruding or protruding portion protruding or protruding. Similarly to the above, the engagement connecting member 51 also includes a side wall portion that extends from the other end portion of the plate-like attachment portion 52 and that can be screwed into the screwing member.

  Such a rail member 41 can also be effectively connected using the engaging connecting member 51 and the connecting pin 21 similar to the above that can be attached to the connecting holes 45a and 45b.

  In the present invention, the short rail member may be connected by at least one of the engaging connecting member and the connecting pin. That is, when the engagement connecting member is used, the connection pin is not always necessary, and when the connection pin is used, the engagement connecting member is not always necessary. In a preferred aspect, adjacent rail members are connected using both the engagement connecting member and the connecting pin.

  Since the engagement connecting member only needs to be disposed in the connection region (adjacent region) of the pair of short rail members, it is usually a member having a short length. Moreover, when connecting a rail member with an engagement connection member, the rail member does not necessarily need to have a connection hole. The plate-like mounting portion of the engagement connecting member only needs to be disposed in a connecting area (adjacent area) of rail members adjacent to each other, corresponding to the width of the rail member. It may have a flat plate shape that can be covered (can be covered). The bent engagement portion formed by bending or curving at one end in the width direction of the plate-like attachment portion is a first engaged portion (concave groove, ridge or extension) formed on the side wall of the rail member. It is only necessary to be able to engage with a protruding or protruding engaging portion, and is not limited to the V-shaped cross section, and may be bent or curved in a U-shaped or U-shaped cross section. In a preferred embodiment, the bending engagement portion is guided downward toward the inner side of the plate-like attachment portion as in the V-shaped cross section so as to guide the first protrusion on the side wall of the rail member to the deep portion. You may have the inclined wall (guide wall) inclined in the direction. Moreover, the bending engagement part may have an accommodation recessed part (accommodating part having a U-shaped cross section or the like) for accommodating the first protrusion on the side wall of the rail member.

  On the side wall formed at the other end in the width direction of the plate-like mounting portion, an advancing / retracting member that can be engaged with or sandwiched by the second engaged portion by advancing / retreating can be mounted. . Such an advancing / retracting member may be a screwing member (screw member) that can be advanced / retracted by being screwed to the side wall as described above, and a plate-like mounting portion by a biasing member such as a spring. May be configured by a claw member (claw member capable of moving forward and backward) that can be urged inwardly and can be engaged with or sandwiched with the second engaged portion. In order to engage the second engaged portion with a simple structure and hold the rail member by a clamping or clamping mechanism, a screwing member is advantageous.

  When such an engagement connecting member is used, a connecting pin that can be mounted in a connecting hole of an adjacent short rail member may be used instead of the connecting pin of the above-described form. This connection pin may assist the connection by the engagement connection member, and may have, for example, an outer diameter that can be inserted into or attached to the connection hole. In a preferred embodiment, the connecting pin is attached to the connecting hole in a retaining state (or in a state where it cannot be prevented).

  In addition, the cross-sectional shape of the connecting pin may be a circular shape or an irregular shape (an elliptical shape, a polygonal shape, etc.) corresponding to the connecting hole, and the connecting hole has a key groove shape. May be key-shaped.

  In a preferred embodiment, as described above, a connecting pin that can connect a plurality of short rail members to each other in the longitudinal direction in a state in which the connecting holes formed in the longitudinal direction of the rail members are prevented from coming off is used. Such a connecting pin may be a pin in which one or more protrusions or protrusions extending in the axial direction (longitudinal direction) and / or the circumferential direction are formed on the peripheral surface thereof. In addition, although you may form a ridge part over the perimeter in the circumferential direction of a connecting pin, usually, in many cases, a plurality of projection parts are formed at intervals in the circumferential direction. Further, it may be formed in the circumferential direction at a predetermined interval in the axial direction.

  Further, the connecting pin includes a shaft portion having a predetermined length (a shaft portion having a cylindrical shape or the like), and a thick cylindrical portion formed in a central region in the axial direction, leaving both side portions of the cylindrical shaft portion. The thick cylindrical portion is provided with a groove portion formed or engraved in parallel or crossing each other. The shaft portion has an outer diameter that can be inserted into the connecting hole, and the thick-walled cylindrical portion has an outer diameter larger than the inner diameter of the connecting hole. By forming the groove portions in such a thick cylindrical portion in parallel or intersecting with each other, even if the outer diameter of the thick cylindrical portion is larger than the inner diameter of the connection hole, it is deformed as the connection pin is pressed into the connection hole. Or the convex part or protrusion part (or protrusion) which can be crushed can be formed.

  7 and 8 are schematic views showing other examples of connecting pins. Similar to the connection pin 21, the connection pin 61 in this example includes a cylindrical shaft portion 62 having a predetermined length that can be inserted into the connection hole, and a central region in the axial direction of the cylindrical shaft portion (both side portions are redundant). And a thick cylindrical portion 63 having an outer diameter larger than the inner diameter of the connecting hole. On the peripheral surface of the thick cylindrical portion, groove portions 64 having a V-shaped cross section (straight horizontally long groove portions) 64 extending in parallel with each other along the axial direction (longitudinal direction) are formed at intervals in the circumferential direction. Due to the engraving of the groove portion 64, a convex strip (laterally long projection portion) 66 having an inverted V-shaped cross section extending in the axial direction (longitudinal direction) is formed on the peripheral surface of the thick cylindrical portion. Even with such a connecting pin 61, the pair of rail members can be tightly connected by mounting or press-fitting into the connecting hole.

  In addition, in the connecting pin having a horizontally long groove portion as shown in FIG. 7 and FIG. 8, the end surface shape of the protrusion formed with the adjacent groove portion may be a triangular shape with a sharp top portion, and the width of the top portion is narrow. It may be in the form of a trapezoid.

  In a preferred embodiment, the groove portion may be formed in the axial direction and the circumferential direction of the thick-walled cylindrical portion to form convex portions or projection portions (vertical and transverse intersecting groove portions) adjacent to the peripheral surface in the vertical and horizontal directions. You may form the convex part or projection part (helical or diagonal crossing groove part) which cross | intersects the diagonal direction with respect to the axial direction of the meat | cylindrical cylinder part, and adjoins alternately with respect to an axis line. Such a groove portion may form a let-like thick cylindrical portion (cross groove portion) or a let portion.

  Furthermore, the cross-sectional shape of the groove portion is not limited to the V-shape, but may be a U-shape or a U-shape. However, from the viewpoint of press-fitting operability, the top portion is opened from the bottom portion (toward the bottom portion). When the groove portion of the narrowing shape is formed, the top portion of the convex portion or the protruding portion is easily deformed or crushed. That is, in many cases, a convex portion or a projection portion having a polygonal pyramid shape (triangular pyramid shape, quadrangular thrust shape, etc.) is formed adjacent to the thick cylindrical portion. Furthermore, the convex portions or the projecting portions may be formed parallel to the axial direction (on the same line in the axial direction), but from the viewpoint of press-fitting operability, alternate forms (staggered form) with respect to the axial direction. It is preferable to form adjacent to each other.

  When the inner diameter of the connecting hole is “1”, the outer diameter of the shaft portion may be about 0.9 to 0.98 (for example, 0.95 to 0.97). The outer diameter of the cylindrical portion may be about 1.01 to 1.1 (for example, 1.02 to 1.05). Further, when the outer diameter of the shaft portion is “1”, the groove portion is 0 to 0.2 (for example, 0.03 to 0.15), preferably 0.04 to 0.1 (from the surface of the shaft portion). For example, it may be formed to a depth of about 0.05 to 0.08). Furthermore, the average diameter (the average value of the minor axis and the major axis in the case of an irregular shape) of the bottom of the convex part or the projecting part is 0.2 to 2 mm (for example, 0.3 to 1.5 mm), preferably 0. It may be about 4 to 1 mm (for example, 0.5 to 0.8 mm). In the oblique intersecting groove portion, the intersecting angle of the groove portion may be about 25 to 75 ° (for example, 30 to 60 °) or about 40 to 50 °.

  Furthermore, the connecting pin can connect the rail member in an arbitrary direction as well as connecting the rail member in the lateral direction without using the engaging connecting member. Further, the clamping mechanism is not limited to the clamping or clamping mechanism using the screwing of the screwing member to the engagement connecting member, and a clamping or clamping mechanism using a pair of plates or the like may be used. FIG. 9 is a schematic sectional view showing still another example of the present invention.

  In this example, the pair of short rail members 71a and 71b includes guide grooves (ant groove-shaped mounting recesses) 72a and 72b on which a slide member (intermediate connecting member) 81 can be slidably mounted along the longitudinal direction. It is provided with connecting holes 73a and 73b formed in the longitudinal direction on the side wall facing the guide groove and having a circular arc cross section in which the connecting pin 21 can be mounted. The rail members 71a and 71b are also provided with receiving grooves (or travel spaces) 74a and 74b on which runners can be freely mounted.

  In such rail members 71a and 71b, a plate-like slide member (intermediate connecting member) 81 is slidably mounted in the guide grooves 72a and 72b at the connecting portion (adjacent portion or boundary portion) of the rail member, and the connecting hole The connecting pin 21 is mounted or press-fitted into the holes 73a and 73b, and the holes of the clamping plate 83 are passed through a plurality of screw members (screw rods) 82 formed (or welded) on the slide member 81 at intervals in the longitudinal direction. The adjacent rail members 71a and 71b can be erected and firmly connected in the vertical direction by screwing and fastening the nuts 74 to the respective screw members (screw rods) 82 through a washer if necessary.

  In addition, the connecting pin is a side end portion (unevenly engaged portion of the side wall) or a side wall (sliding portion) of the rail member, such as the engaging connecting member, the holding member or the holding mechanism using the slide member and the holding plate. In many cases, it is used together with a clamping mechanism or a clamping mechanism for clamping and holding an extended side wall that narrows and extends from an opening such as a groove.

  As described above, the present invention includes the engagement connecting member (a pinching connection member or a pinching connection member) and a connection pin, and a connection set for connecting the rail member; connecting the rail member and the engagement connection member A connecting structure including a pin is also included. In such a connection structure, the engagement connection member is attached to the wall; the engagement connection member plate-like attachment portion is connected to an adjacent short rail member in the state where the end faces are abutted or opposed (adjacent to each other). And a first engagement portion (such as a groove or a ridge) of the rail member is engaged with the bending engagement portion of the engagement connecting member, Advancing and retracting members such as screw members are moved forward and engaged with second engaged portions (such as concave grooves or protrusions) of the rail member; both side portions of the connecting pin are respectively connected to the connecting holes of the adjacent rail members. By mounting or press-fitting, adjacent rail members can be connected or constructed.

  When such an engagement connecting member and / or connecting pin is used, even if the length of the rail member is significantly shortened, it can be connected to a long rail member, and the storage and transportation space for the rail member can be greatly reduced. In particular, since the weight of the rail member is large, the transportation cost of the rail member can be greatly reduced. For example, even if the length of the short rail member is, for example, about 1 to 5 m, preferably about 1 to 3 m (for example, 1.5 to 2.5 m), the engagement connecting member and / or the connecting pin is used. By this, according to a construction place, it can be connected or extended to arbitrary length, for example, 3-10 m or more. The rail member is not limited to a straight rail member, and may be a curved or curved or bendable rail member.

  The rail member can be formed of various materials, and is usually formed of a metal such as aluminum, iron (steel), or a metal alloy (stainless steel).

  The type of runner that can travel with respect to the rail member is not particularly limited, and a pair of wheels, a shaft portion that connects the wheels, a support portion that rotatably supports the shaft portion, and a support portion It may be provided with an attachment portion (such as a hook portion) that is attached and is used to lock or attach a traveling body (a shield such as a curtain, a carrier such as a component). Further, the attachment portion may be attached to the support portion so as to be swingable, and a shaft portion rotatable in the circumferential direction may be interposed between the support portion and the attachment portion.

  The present invention can easily and easily connect a plurality of short rail members adjacent to each other, and can form a long rail having a desired length. Moreover, a rail member can also be attached with respect to a wall part (an upper wall, a side part wall, especially ceiling wall), and can also be attached in the form of a support | pillar. Therefore, it is useful for constructing rail members and partitioning various spaces such as indoor spaces and outdoor spaces (outdoor spaces for renovation and renovation of buildings such as houses and apartment buildings). It is also useful for transporting or moving the object to be transported along.
