Description

  The present invention relates to an eaves support.

  2. Description of the Related Art Conventionally, a spring washer in which a stepped portion in which an annular part is cut into a step shape is provided with a spring property is used for a lateral rotation lock type eaves support (see, for example, Patent Document 1). In this eaves support, the spring washer is placed on the back surface of the bolt head or the back surface of the nut, and the step is pressed against the flange (bolt head or nut) by screwing and fastening the bolt and nut. Springiness acts.

  In the eaves rod support tool described in Patent Document 1, a rivet is used as a fixing tool for fastening an object member, and a spring washer is attached to the caulking portion side of the rivet. Unlike bolts and nuts, rivets are often used for semi-permanent fastening applications. Like the above-mentioned eaves support, the rivet is locked by rotating operation. A rivet that does not sag when moved to a position is preferably used as a fixture.

JP 2002-332729 A

  As described above, this type of spring washer has a structure using bolts and nuts, and unless the bolt and nut are defective, the stepped portion of the spring washer is reliably pressed by screwing the bolt and nut. The resilience works without any problem.

  On the other hand, when the spring washer is used for a rivet, the caulking portion is formed by using a tool such as a rivet hammer, and may be formed in a distorted state with respect to the rivet shaft. That is, in such a case, the back surface of the rivet caulking part may not be parallel to the surface of the target member to which the rivet is attached. For those having such caulking defects, the pressing force of the flange portion (caulking portion) acts only on the portion where the spring washer is biased. Therefore, there is a possibility that the pressing force does not act on the step portion of the spring washer, and in that case, the elastic force does not act naturally. Therefore, there is a possibility that slack between the members may occur even in the locked state.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide an eaves-holding support device in which the spring property acts properly even when the pressing portion by the fixing device is biased. There is.

  In order to achieve the above-mentioned object, the eaves rod support device according to claim 1 is formed in a plate shape having a long hole and is slidably connected to the mounting rod, and a hook support portion at both ends in the longitudinal direction. An eaves bowl comprising a main body having a heel support and a lock lever that is pivoted in the horizontal direction, and is connected by a fixing tool that overlaps and vertically penetrates, and the heel support body is fixed at a desired position. In the support tool, the lock lever has a substrate portion that is arranged substantially parallel to the heel support tool body, and the substrate portion has an insertion hole through which the fixing tool is inserted, and is fixed. The fixture is provided with flange portions that sandwich the heel support main body and the mounting rod at both ends thereof, and the flange portion of the fixture that is inserted below the bottom surface of the lock lever substrate portion and the insertion hole of the substrate portion. Are provided with a plurality of spring tongues along the circumferential direction of the insertion hole. It is possible to switch between the locked position and the unlocked position by the rotation operation, and at the locked position, the spring tongue is elastically deformed so that the elastic force acts between the flange portion and the substrate portion. On the other hand, the spring tongue piece is in a return state when in the unlocked position.

  According to a second aspect of the present invention, the spring tongue piece is formed by cutting and raising a part of the substrate portion of the lock lever.

  According to a third aspect of the present invention, the spring tongue is provided on a separate spring washer, and the spring washer is provided on either the base plate portion of the lock lever or the flange portion of the fixture. It is arranged to stand up.

  Since the eaves hook support tool according to claim 1 has the above-described configuration, even when the fixing tool cannot press the spring tongue piece evenly and presses only the biased portion, any spring tongue piece is pressed. It is elastically deformed and elastic force acts. Therefore, there is no possibility that a shift occurs in the locked position.

  Since the eaves hook support tool according to claim 2 has the above-described configuration, the eaves hook support tool can have a spring action without using other members such as a spring washer. In addition, the number of parts can be reduced.

  Since the eaves-holding support tool according to claim 3 has the above-described configuration, if a spring washer having the above-described configuration is added to an existing eaves-holding support tool, an integrated one (the one according to claim 2) ) And the same effect.

(A) is a top view which shows the other example of a spring tongue piece, (b) is the elements on larger scale which correspond to the AA line of (a).

  Below, the eaves hook support tool which concerns on embodiment of this invention is demonstrated based on an accompanying drawing. First, the basic structure of the spring washer 1 used for the eaves hook support A shown in FIG. 5 will be described.

  As shown in FIGS. 1A and 1B, the spring washer 1 is a washer having an insertion hole 1a for penetrating the fixture 3 at the center. This spring washer 1 is provided with a plurality of spring tongues 1b on the outer side of the insertion hole 1a substantially along the circumferential direction.

  Since the spring washer 1 has such a shape, when the target member is fastened with the fixture 3 using the spring washer 1, the spring property is evenly used at any position in the circumferential direction in the circumferential direction. I can get it. Therefore, the spring washer 1 acts regardless of the state of the fixture 3.

  Next, the detailed configuration and effects of the spring washer 1 shown in FIG. 1 will be described.

  As described above, the spring washer 1 has the insertion hole 1a for fixing tool penetration at the center, and three spring tongues 1b on the outer side. A shaft portion 3b of a shaft-shaped fixture 3 such as a bolt 3A (see FIG. 3) and a rivet 3C (see FIG. 5) is inserted through the insertion hole 1a.

  The spring tongue piece 1b is formed in the shape of a curved strip along the circumference (arc) at the outer peripheral edge portion, and these three pieces have substantially the same shape and substantially the same size. These spring tongues 1b are preferably approximately the same shape and approximately the same size so that the spring property acts equally, but if the spring property acts at any position in the circumferential direction, the shape and dimensions It doesn't have to be the same.

  The spring tongue 1b is provided with a short cut 1d corresponding to the width dimension of the spring tongue 1b toward the center from the outside of the disc body, and the notch 1d adjacent in the circumferential direction from the center side end of the cut 1d. It is formed by making a long cut 1e so as to approach the end. The notches 1d and 1e desirably have a certain width so that the spring tongue 1b can easily operate without being caught in the thickness direction of the spring washer 1 as shown in the figure.

  As shown in FIG. 1A and FIG. 2, the base end portion 1ba of the spring tongue piece 1b is located on a plane substantially the same height as the circular central portion 1c inside the spring tongue piece 1b, and is located on the tip end portion 1bb. It has a shape that slopes toward it. More specifically, the outer peripheral part of the insertion hole 1a and the base end part 1ba of the spring tongue 1b are continuously formed on the same plane.

  2 (a) shows a steady state in which the spring tongue 1b is elastically restored, and the spring washer 1 places the tip 1bb of the spring tongue 1b on the surface of the target member 4 to which the fixture is attached. The state of being placed is shown. In this state, the end portion of the fixture 3 (bolt head 3Aa (see FIG. 3), nut 3B (see FIG. 3), rivet head 3Ca of the rivet 3C (see FIG. 5 (a)) or caulking portion 3Cb (see FIG. 5) of the rivet 3C. 5 (a)))), the spring washer 1 is compressed and the spring tongue piece 1b is not inclined, and the surface of the spring tongue piece 1b is the center of the circle. It becomes substantially flush with the surface of the portion 1c.

  Further, as shown in FIG. 2B, the spring washer 1 may be arranged upside down. In this case, the surface of the circular central portion 1c of the spring washer 1 is in contact with the target member 4, and the spring tongue 1b. The front end portion 1bb is arranged on the back side of the flange portion 3a of the fixture 3. In this case, in order to make the spring washer 1 springy, as shown in FIG. 2 (b), the spring washer 1 and the fixture 3 are provided with a tip 1bb of the spring tongue 1b. A dimensional relationship that contacts the flange portion 3a of the fixture 3 is required.

  FIG. 3 shows an example in which the spring washer 1 is arranged on the side of the nut 3B, which is the fixture 3, and the spring washer 1 arranged as shown in FIG. 2A is pressed and clamped between the bolt 3A and the nut 3B. The central part is pressed and is compressed and deformed into a flat shape.

  As described above, the spring washer 1 is formed with the spring tongue piece 1b on substantially the entire circumference along the circumferential direction. Therefore, when fastening the target member 4 using the fixture 3, at least one of The spring tongue 1b is elastically deformed, and the spring action is almost certainly exhibited. Therefore, if this spring washer 1 is used, it will not happen that the spring property cannot be used.

  4A and 4B are explanatory views of a spring washer 1 according to another embodiment. The spring washer 1 has four spring tongues 1b that are linear in a plan view and are formed substantially along the circumferential direction, and are inclined in the same direction (clockwise in the illustrated example). Two pieces of the spring tongues 1b are opposed to each other, and those having substantially the same shape and the same size are arranged at substantially equal intervals in the circumferential direction. Further, the base end portion 1ba of the spring tongue piece 1b is substantially flush with the circular central portion 1c.

  Since it has such a configuration, the same effect as that shown in FIG.

  Further, since the spring washer 1 shown in FIG. 1 has the spring tongue piece 1b formed on the outer peripheral edge portion, the spring washer 1 can be easily formed and the manufacturing cost can be reduced. On the other hand, the spring washer 1 shown in FIG. Since 1b is formed on the inner side of the outer peripheral edge, the pressing force by the fixture 3 is easily transmitted to the spring tongue 1b, and is suitable for the case where the fixture 3 having a small diameter flange portion 3a (bolt head 3Aa, etc.) is used. ing.

  These spring washers 1 can also be used for fastening with rivets 3C (see FIG. 5). In particular, the caulking portion 3Cb of the rivet 3C may not be formed in parallel to the outer surface of the target member 4 fastened by the rivet 3C. When the caulking portion 3Cb has a problem as described above, the pressing force by the caulking portion 3Cb (flange portion 3a) acts only on a portion where the spring washer 1 is biased. Since 1b is formed over the entire circumference, the spring property of the spring washer 1 can be utilized.

  The rivet 3C is often used for semi-permanent fastening applications, and the spring washer 1 is used for various members having such a purpose. As a member using the rivet 3 </ b> C, an eaves support that can be switched between tightening and loosening by rotating the operation unit will be described with reference to FIGS. 5 to 7.

  The eaves support A is a support that can vary the degree of protrusion from the wall surface or the like that is the attachment site to the eaves 5 (the eaves support body 20 that supports the eaves 5).

  The eaves support A is slidably connected to the mounting rod 10 and has a long hole 23 and is formed in a plate shape. The eaves support main body 20 has hook support portions 22 at both ends in the longitudinal direction. And a lock lever 30 that is rotated in the horizontal direction, and these are overlapped and connected with a fixture 3 (rivet 3C in the example of FIG. 5) that penetrates up and down, and the heel support body 20 is fixed at a desired position. Is a supported tool.

  The eaves support A is further configured with the spring washer 1 of the present invention illustrated in FIG. Moreover, the fixing tool 3 is provided with flange portions 3a that sandwich the heel support body 20 and the mounting rod 10 at both ends thereof.

  The shaft 3b of the fixture 3 is inserted between the outer surface of the target member 4 to be connected by the fixture and the flange portion 3a on the outer surface side on at least one side of the rod support body 20 and the attachment rod 10. A spring washer 1 is interposed.

  The eaves support A can be switched between a locked position and an unlocked position by rotating the lock lever 30. In the locked position, the spring washer 1 is elastically deformed by the spring tongue 1b. While being sandwiched between the portion 3a and the target member 4, when in the unlocked position, the spring tongue 1b is in the return state.

  As the spring washer 1 used in the eaves support A, the one shown in FIGS. 1 and 4 is used. That is, the spring washer 1 is a washer having an insertion hole 1a for passing through a fixture at the center, and includes a plurality of spring tongues 1b extending substantially along the circumferential direction outside the insertion hole 1a. Yes. In addition, in the main eaves support A, the spring washer 1 illustrated in FIG. 1 is used.

  Since the eaves support A is configured as described above, the spring property of the spring washer 1 is expressed even when the fixture 3 cannot press the spring washer 1 evenly and presses only the biased part. Therefore, there is almost no possibility that the lock is loosened at the lock position.

  Hereinafter, the configuration of the eaves support A will be described in detail with reference to FIGS.

  The four members, which are the main members constituting the eaves support A, that is, the mounting rod 10, the main body 20 of the support, the stopper washer 40, and the lock lever 30, are connected by the overlapping rivet 3C (fixing tool 3) in the above-described order. It is what is done. The lock lever 30 is a member for switching between lock and unlock. When the lock lever 30 is rotated in the horizontal direction and moved to the lock position, the four members are locked (fixed), and the unlock position is reached. When this is operated, the heel support main body 20 can be slid for adjusting the condition of the protrusion. That is, in the unlocked position, the lock lever 30 remains at a fixed position with the shaft position unchanged from that of the mounting rod 10, and only the rod support body 20 sandwiched between them slides.

  The eaves support A is provided with a lock mechanism that locks the slide by fixing the heel support body 20 to the mounting rod 10 and releasing the unlocking. There are various mechanisms for this lock mechanism. Here, as an example, a mechanism provided with a lock lever 30 and a stopper washer 40 is illustrated.

  The lock lever 30 includes a substrate portion 31 having a shaft hole portion 32 through which the shaft portion 3b of the rivet 3C passes, and a grip portion 33 extending downward from a side end of the substrate portion 31. . Two lock recesses 34 for locking are formed at a substantially central position between the gripping portions 33 in the substrate portion 31. A shaft hole 32 is formed in the approximate center of these lock recesses 34.

  The stopper washer 40 is a rectangular plate-like body having substantially the same shape and substantially the same size as the substrate portion 31 of the lock lever 30. Before and after the stopper washer 40 on the lower surface side, a bulging portion 42 that is long in the width direction and bulges in a mountain shape is formed. A substantially hemispherical navel portion 42 a is formed at the center of the peak of the bulging portion 42. A shaft hole 41 through which the shaft 3b of the rivet 3C passes is formed in the center of the stopper washer 40.

  Further, on the upper surface side of the stopper washer 40, a pair of locking pieces 43 that are locked to the concave portions 24 a of the concave and convex portions 24 formed on the lower surface of the saddle support main body 20 at symmetrical positions before and after the shaft hole portion 41 are provided. I have.

  When the four members of the mounting rod 10, the rod support body 20, the stopper washer 40, and the lock lever 30 are connected by the rivet 3C and the lock lever 30 is arranged in the direction shown in FIG. 5 (lock position), FIG. As shown to (a), the bulging part 42 of the stopper washer 40 and the locking recessed part 34 of the lock lever 30 overlap, and the navel part 42a of the bulging part 42 corresponds to the position of the locking recessed part 34. In this example, since the lock recess 34 is formed by a hole, the navel portion 42a is exposed on the lower surface side as shown in FIG.

  The attachment rod 10 has a foot piece 12 extending from the center of the upper end of the attachment foot plate 11 fixed to the eaves or the like toward the front, and has a connecting piece portion 13 formed in a stepped manner in front of the foot rod 12. It becomes. The connecting piece portion 13 is provided with a shaft hole portion 14 that is connected to the hook support body 20, the stopper washer 40, and the lock lever 30 that are disposed and overlapped with each other by the fixture 3.

  The heel support main body 20 has hook ear support portions 22 for suspending and supporting the eaves ridge 5 as shown in FIG. 5 at both front and rear ends of the long plate-like slide plate main body 21. Note that the ear support 22 is not limited to the illustrated example, and various types can be adopted depending on the shape of the eaves 5.

  A long hole 23 is formed along the longitudinal direction at the center of the slide plate body 21 in the width direction. The long hole 23 is a slide hole for adjusting the degree of protrusion for overlapping and coupling between the mounting rod 10 and the lock lever 30.

  On both sides in the width direction of the long holes 23 on the plate surface of the slide plate main body 21, uneven portions 24 that are continuous in the longitudinal direction are formed. In addition, although the continuous unevenness | corrugation has exposed on the upper and lower surfaces in the scissors support body 20 of this example, continuous unevenness | corrugation may be formed only in the lower surface.

  As shown in FIG. 5, the eaves support A is configured by inserting a rivet 3 </ b> C from above into each shaft hole of the four members of the mounting support 10, the support body 20, the stopper washer 40 and the lock lever 30. The spring washer 1 is inserted into the lower end of the rivet 3C protruding below the base plate portion 31 of the 30 and then the lower end thereof is caulked to be connected.

  As shown in FIG. 5 (b), the spring washer 1 shown in FIG. 1 is reverse to that shown in FIG. 2 (a), and the spring tongue 1b is a lock lever. It arrange | positions so that the back surface of 30 board | substrate parts 31 may be touched.

  FIG. 6 is a schematic bottom view of the eaves hook support A in which the four members are connected by rivets 3C. FIG. 6A is a schematic bottom view of the lock position, and FIG. 6B is a schematic bottom view of the unlock position. Further, FIG. 7A is a schematic longitudinal sectional view of the eaves support A corresponding to the locked position, and FIG. 7B is a schematic longitudinal sectional view of the eaves supporting tool A corresponding to the unlocked position. . In addition, each figure of Fig.6 (a) (b) and Fig.7 (a) (b) is a schematic diagram. Moreover, the lock lever of FIG.7 (b) respond | corresponds to what was shown by the dashed-two dotted line of FIG.6 (b).

  As shown in FIGS. 6 (a) and 7 (a), the lock position means that the longitudinal direction of the base plate 31 of the lock lever 30 is the longitudinal direction of the heel support body 20 as shown in FIG. 5 (a). On the other hand, as shown in FIGS. 6 (b) and 7 (b), the unlocked position refers to the longitudinal direction of the base plate portion 31 of the lock lever 30 in the longitudinal direction of the heel support main body 20. The position is not right.

  More specifically, the lock position refers to the base plate portion 31 of the lock lever 30 riding on the bulging portion 42 of the stopper washer 40, the navel portion 42a of the bulging portion 42 entering the lock concave portion 34 of the base plate portion 31, and This refers to the position where the locking piece 43 of the stopper washer 40 has entered and locked into the concave portion 24a of the concave-convex portion 24 (see FIGS. 6A and 7A). At this time, the saddle support main body 20, the stopper washer 40, and the substrate portion 31 of the lock lever 30 are in a state of being pressed and fixed to each other.

  The unlock position refers to a position in which the base plate portion 31 of the lock lever 30 is disengaged from the bulging portion 42 of the stopper washer 40 (see FIGS. 6B and 7B). At this time, the saddle support main body 20, the stopper washer 40, and the substrate portion 31 of the lock lever 30 are in a state in which the mutual pressure contact fixing is released.

  When the rotation angle of the lock lever 30 is slight (when the lock recess 34 is displaced from the navel portion 42a), a part of the base plate portion 31 of the lock lever 30 remains on the bulging portion 42. In this state, the eaves 5 is not installed, and no sliding operation is performed. In other words, if the base plate portion 31 of the lock lever 30 rides on the bulging portion 42 and is locked at the position shown in FIG. 6A, the stopper washer 40 and the lock recess 34 where the navel portion 42a is not formed. You may use the lock lever 30 which is not formed.

  When the eaves hook support A is in the locked position, the spring tongue 1b of the spring washer 1 is pressed against the flange portion 3a of the caulking portion 3Cb of the rivet 3C, and becomes flat and flat like FIG. On the other hand, in the unlocked position, the pressure contact fixing is released, and accordingly, the spring tongue 1b of the spring washer 1 returns.

  As shown by the two-dot chain line in FIGS. 7A and 7B, when the caulking portion 3Cb is formed to be inclined, a part of the flange portion 3a (left side in the drawing) even in the locked position However, since the other part (the right side in the drawing) presses the spring washer 1, the spring property (elastic return force) is developed.

  As described above, the spring washer 1 is particularly effective when attached to the caulking portion 3Cb side of the rivet 3C. As in the main eaves support A, when the positional relationship between the caulking portion 3Cb and the spring washer 1 is changed by repeatedly switching between the lock position and the unlock position, the spring washer 1 has the above-described configuration. In the position, the spring washer 1 is almost surely elastic. The spring washer 1 may be arranged on the rivet head 3Ca side.

  Next, the eaves hook support B provided integrally with the spring tongue 32b will be described with reference to FIGS. In addition, about the site | part common to the eaves hook support tool A (refer FIGS. 5-7) in this eaves support tool B, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  Unlike the eaves cage support A of FIG. 5, the eaves cage support B does not use the spring washer 1, and instead, a spring tongue 32 b is formed on the lock lever 30. The spring tongue 32 b is formed by cutting and raising a part of the base plate portion 31 of the lock lever 30. Note that the lock / unlock operation and the structure of the eaves hook support tool B by the operation of the lock lever 30 are the same as those in FIGS.

  FIG. 8A is a view of the central portion of the substrate portion 31 of the lock lever 30 as viewed from the back side. An insertion hole 32a including a shaft hole portion 32 is formed in the center portion of the substrate portion 31, and three spring tongue pieces 32b are formed on the outer periphery thereof.

  The spring tongue 32b has a curved shape along the circumferential direction in plan view, and the base end portion 32ba to the tip end portion 32bb rise in an inclined manner between the gripping portions 33 of the lock lever 30 by cutting and raising. This spring tongue piece 32b is pressed against the flange portion 3a of the caulking portion 3Cb of the rivet 3C, and becomes flat and flat, thereby exhibiting springiness (elastic return force).

  FIG. 9A is a view of the state when the eaves hook support B is in the locked position, and the spring tongue 32b is pressed against the flange portion 3a of the caulking portion 3Cb of the rivet 3C. Moreover, FIG.9 (b) is a figure of the state when the eaves hook support tool B exists in an unlocking position, and the spring tongue piece 32b is in a reset state.

  Thus, even if the positional relationship between the caulking portion 3Cb and the spring washer 1 is changed by repeatedly switching the lock position and the unlock position as in the main eaves support B, the spring tongue 32b is formed as described above. Therefore, the spring tongue 32b exhibits the spring property almost certainly at the locked position, and the locked state is maintained.

  Thus, the basic configuration of the eaves support A and B shown in the above two embodiments is as follows.

  The eaves supporters A and B are slidably connected to the mounting rod 10 and have a long hole 23 and are formed in a plate shape. The eaves support main body 20 has hook support portions 22 at both ends in the longitudinal direction. And a lock lever 30 that is pivoted in the horizontal direction, and these are connected by a fixture 3 that overlaps and vertically penetrates, and the heel support tool body 20 is fixed at a desired position.

  The lock lever 30 has a substrate portion 31 disposed substantially parallel to the heel support tool main body 20, and the substrate portion 31 has an insertion hole 32 a through which the fixing tool 3 is inserted at substantially the center. . Moreover, the fixing tool 3 is provided with flange portions 3a that sandwich the heel support body 20 and the mounting rod 10 at both ends thereof. In addition, between the lower surface of the substrate portion 31 of the lock lever 30 and the flange portion 3a of the fixture 3 that is inserted below the insertion hole 32a of the substrate portion 31, a plurality of pieces are provided along the circumferential direction of the insertion hole 32a. Spring tongues 1b and 32b are provided.

  The lock lever 30 can be switched between a lock position and an unlock position by rotating the lock lever 30. In the locked position, the spring tongue pieces 1b and 32b are elastically deformed and fixed so that a resilient force acts between the flange portion 3a and the base plate portion 31, while in the unlocked position, the spring tongue pieces 1b. , 32b are in the return state.

  According to such eaves supporting tools A and B, even when the fixing tool 3 cannot press the spring tongue pieces 1b and 32b evenly and presses only the biased portion, any one of the spring tongue pieces 1b and 32b It is pressed and elastically deformed, and elastic force acts. Therefore, there is no possibility that a shift occurs in the locked position.

  Moreover, the eaves hook support A shown in FIG. 5 can be simply comprised only by adding the spring washer 1 mentioned above to the existing eaves hook support. On the other hand, the eaves bar support B shown in FIG. 9 can give the eaves bar support B a spring action without using other members such as the spring washer 1. In addition, the number of parts can be reduced.

  Next, still another example of the spring tongue pieces 1b and 32b will be described with reference to FIGS. The spring tongues 1 b and 32 b may be formed on the spring washer 1 or on the base plate portion 31 of the lock lever 30.

  The spring tongue pieces 1b and 32b shown in FIG. 1, FIG. 4 and FIG. 8 are all strip-like ones extending along the outer circumferential direction of the insertion holes 1a and 32a, but the spring tongue pieces 1b shown in FIG. As shown in FIGS. 10 (a) and 10 (b), 32b rises in an inclined shape toward the central insertion holes 1a and 32a.

  A two-dot chain line in FIG. 10 (a) indicates a substantially center position of the flange portion 3a of the caulking portion 3Cb of the rivet 3C, and the flange portion 3a presses any of the spring tongue pieces 1b and 32b. ing.

  In this example, three spring tongues 1b and 32b are provided in the circumferential direction, but unlike those of FIGS. 1, 4 and 8, the gap between the spring tongues 1b and 32b is wide and pressed by the flange 3a.
