Description
Technical Field
The present invention relates to a panel fastener for joining two panels.
Background
Conventionally, various panel fasteners have been proposed for quickly and easily joining two panels to each other when assembling an assembled rack, a cabinet, or the like, which is composed of a plurality of panels.
A panel fastener of the above kind is disclosed in JP2010-270770 a. The fastener of the above document includes: the panel mounting device comprises a central rotating shaft, a locking piece arranged at the front end part of the central rotating shaft in the panel insertion direction, a fixing piece rotating operation part arranged at the tail end part of the central rotating shaft in the panel insertion direction, a holding mechanism which is formed by extending the central rotating shaft and the locking piece in the same direction and fixes the fixing piece on the mounting panel, and a clamping part for limiting the rotation of the fixing piece. A groove portion which can be operated by a coin or a straight screwdriver is formed on the front side of the fixing member rotation operation portion. Further, as the holding mechanism, an arm portion is formed orthogonal to the central rotation axis.
On the other hand, a mounting hole is formed at a fastener mounting position of the mounting panel. The mounting hole portion has: the locking device includes a rotation shaft support portion composed of a pair of protruding portions that hold a central rotation shaft of the stator, a through portion through which the locking piece and the arm portion can pass, and a rotation restricting portion that engages with an engagement portion formed in the stator. The pair of protruding portions of the rotation shaft support portion are formed with hole portions having a small diameter for holding the center rotation shaft. One rotation restricting portion restricts the rotation of the stator in the counterclockwise direction, and the other rotation restricting portion restricts the rotation of the stator in the clockwise direction, restricting the maximum rotation angle of the stator to 90 degrees.
Further, a locking hole portion is formed at a fastener attachment position of the body panel. The locking hole has a rotation axis through-hole through which the center rotation axis of the fastener can pass, and a locking piece through-hole through which the locking piece can pass. In addition, the bent portions are formed at both ends of the main body panel, and the thickness of the arm portion of the fixing member is absorbed by the space portion formed between the bent portions and the mounting panel.
In this way, the mount is inserted into the mount hole portion formed in the mount panel from the front side of the mount panel, and after the mount is held by rotating in the counterclockwise direction, the back side of the mount panel is brought into contact with the body panel, and the tip end portion of the mount is inserted into the engagement hole portion formed in the body panel and rotated in the clockwise direction, whereby the mount panel is fixed to the body panel. With such a panel mounting structure, two panels can be joined quickly and easily.
However, since the conventional panel fastener is rotationally fixed through the mounting holes of the two panels, a tool for rotating the panel fastener is required, which results in a problem that the mounting work of the panel fastener is complicated. Further, since the mounting hole portion is provided in one of the two panels and the locking hole portion is provided in the other panel, and the holes are formed in different special shapes, the shapes of the holes are complicated, and the cost required for drilling the holes is increased.

Referring to fig. 2 and 3, the pair of claw plates 3 respectively have: a first surface portion 301 on one end side corresponding to the projecting edge portion 201 of the support plate 2 in a retracted state shown in fig. 6 (2) described later; a second face portion 302 corresponding to the other end side of the edge 202 opposite to the protruding edge portion 201 of the support plate 2; a third surface portion 303 corresponding to the side edge portions 203 and 204 of the support plate 2 and arranged on the outer side surface side of the support plate 2; and a fourth surface portion 304 which is opposed to the third surface portion 303 and is disposed on the inner side surface side of the support plate 2.
As shown in fig. 2, the pair of claw plates 3 are formed symmetrically with respect to the longitudinal center position as the center of symmetry in the rectangular plane of the pair of support plates 2, respectively, so as to have a size that can be arranged in the half plane of the rectangular plane. As shown in fig. 2 and 3, the rotation center of each claw plate 3 is provided near the third surface portion 303 corresponding to the side edge portions 203 and 204 of the support plate 2 on the first surface portion 301 side corresponding to the protruding edge portion 201 of the support plate 2, and a shaft insertion portion 30 through which the shaft 4 can be inserted is formed at this position. The second surface portion 302 corresponding to the edge portion 202 of the support plate 2 is formed in a part of a circle having a center placed closer to the first surface portion 301 and closer to the fourth surface portion 304 than the rotation center of the claw plate 3, that is, in an arc shape.
As shown in fig. 3, in each claw plate 3, in a retracted state shown in fig. 6 (2) described later, the third surface portion 303 is formed as a flat surface having a straight cross section parallel to the side edge portions 203, 204 of the support plate 2. The claw portion 31 is defined as a portion from the second surface portion 302 to the third surface portion 303. The first surface portion 301 has a complex shape, and a part of the third surface portion 303 side thereof is formed as a flat surface having an arc-shaped cross section with the center of a circle positioned at the rotation center of the claw plate 3, and the remaining part of the fourth surface portion 304 side thereof is formed as a flat surface inclined symmetrically to the third surface portion 303 with the rotation center of the claw plate 3 as the center of symmetry. The fourth surface portion 304 is formed as a flat surface facing in a direction parallel to or slightly open from the third surface portion 303, in this embodiment, slightly open from parallel.
A convex rotation restricting portion 32 having a trapezoidal cross section in the present embodiment is provided at an end portion of the second surface portion 302 of each claw plate 3 on the fourth surface portion 304 side so as to be engageable with the stopper 21 of the mounting plate 1.
Further, a cylindrical hole 33 is formed in the fourth surface portion 304 of each claw plate 3. As shown in fig. 2, the coil spring 5 is used as a spring member, and both ends of the coil spring 5 are held in the holes 33 of the pair of claw plates 3 and interposed between the two claw plates 3. As shown in fig. 2 and 3, the hole 33 of each claw plate 3 is formed at a predetermined angle with respect to the fourth surface portion 304. The above angle is determined as follows: when the panel mount F is attached to the attachment holes 61, 62 of the two panels P1, P2, the coil spring 5 can be deformed into an arc shape protruding toward the attachment plate 1 side when the claw portions 31 of the claw plates 3 protrude from the both side edge portions 203, 204 of the support plate 2 as shown in fig. 6 (1) and (3) before and after the pair of support plates 2 and the pair of claw plates 3 are passed through the attachment holes 61, 62 together. A portion 331 of the inner peripheral surface of the hole 33 on the second surface portion 302 side is inclined at a predetermined angle so as to gradually increase in diameter from the back side toward the opening side of the hole 33. The above angle is determined as follows: while the pair of support plates 2 and the pair of claw plates 3 are passing through the mounting holes 61, 62 together, as shown in fig. 6 (2), when the claw portions 31 of the claw plates 3 are retracted inside the both side edge portions 203, 204 between the support plates 2, the coil spring 5 can be deformed into an arc shape protruding to the side opposite to the mounting plate 1.
Each part of the panel fixing member F has a configuration in which, as shown in fig. 2, the pair of claw plates 3 are arranged between the pair of support plates 2 symmetrically with the position of the center in the longitudinal direction of the support plate 2 as the center of symmetry, and the shaft 4 is inserted through the shaft insertion portions 20 near the both side corners on the projecting end 201 side of the support plate 2 and the shaft insertion portions 30 of the claw plates 3, and is assembled to be rotatably supported between the pair of support plates 2. Both ends of each shaft 4 are swaged and fixed in the tapered inclined portion 200 of the support plate 2.
In this way, the panel fastener F is configured such that the pair of support plates 2 and the pair of claw plates 3 pass through the mounting holes 61 and 62 of the two panels P1 and P2 together by pushing down, and the pair of claw plates 3 are locked to the edge of the mounting hole 62 of the panel P2.
Fig. 4 and 5 illustrate the case where the panel fixing member F is used for assembling the assembled rack R. The frame R is composed of a top panel, a bottom panel, left and right side panels, a front door panel, and a back panel. A rectangular mounting hole is bored in each panel at a fixed position, and the rack R is assembled by aligning the mounting holes of two adjacent panels and inserting and locking the panel fasteners F.
Hereinafter, a method of using the panel fastener F and the function of the panel fastener F will be specifically described. In addition, the method of use of the panel fastener F is the same between any two adjacent panels, and therefore, the joined panels are not specifically referred to herein, but merely as two panels P1, P2 or a first panel P1 and a second panel P2, etc. The first panel P1 is a panel on which the mounting hole 61 is the outside when the two panels P1 and P2 are overlapped, that is, a panel on which the panel fastener F is inserted, and the second panel P2 is a panel on which the mounting hole 62 is the inside when the two panels P1 and P2 are overlapped, that is, a panel on which the panel fastener F protrudes.
As shown in fig. 5 and (1) of fig. 6, the normal state before use of the panel fastener F is as follows: the pair of claw plates 3 are pressed and biased in the direction of both side edge portions 203, 204 of the support plate 2 by the coil springs 5 between the pair of support plates 2, and claw portions 31, which are portions of the claw plates 3 from the third surface portion 303 to the second surface portion 302, protrude outward from both side edge portions 203, 204 of the support plate 2. Further, on the mounting surface of the mounting plate 1, a pair of stoppers 21 are formed between the pair of support plates 2 on the side of both side edge portions 203, 204, and a convex rotation restricting portion 32 engageable with each stopper 21 is provided at the end portion on the side of the fourth surface portion 304 of the second surface portion 302 of each claw plate 3, so that the claw plate 3 is reliably prevented from flying out from between the support plates 2.
As shown in fig. 5 and 6, when the above-described assembled rack R is assembled, the two panels P1 and P2 are overlapped, the mounting holes 61 and 62 of the two panels P1 and P2 are aligned, the panel fastener F is aligned in the direction of the mounting holes 61 and 62, the lateral direction is the lateral direction, and the longitudinal direction is the longitudinal direction, and the pair of support plates 2 and the pair of claw plates 3 are inserted together into and pressed (pushed) into the mounting holes 61 and 62 of the two panels P1 and P2.
Thus, as shown in fig. 6, both side edge portions 203, 204 and both outer side surfaces of the support plate 2 of the panel fastener F slide from the front end to the middle and from the middle to the base end at the edge portions in the short-side direction and the long-side direction of the attachment holes 61, 62 of the panels P1, P2, and pass through the attachment holes 61, 62. During this time, the claw portions 31 of the pair of claw plates 3 protruding outward from the both side edge portions 203, 204 of the pair of support plates 2 are pressed against the respective short-side direction edge portions of the mounting holes 61, 62 of the panels P1, P2, gradually rotate inward between the support plates 2 against the biasing force of the coil spring 5 between the claw plates 3 (while compressing the coil spring 5), and retract inward between the both side edge portions 203, 204 of the support plates 2. Next, at the moment when the panel fastener F is pushed into the mounting holes 61 and 62, the pair of claw portions 31 are completely retracted between the support plates 2, the support plates 2 completely pass through the mounting holes 61 and 62 of the panels P1 and P2, and the flange 11 of the mounting plate 1 abuts against the entire periphery of the mounting hole 61 of the outer panel P1. The pair of claw plates 3 between the support plates 2 pass through the mounting holes 61, 62 of the panels P1, P2, and are elastically locked to the edge peripheries in the short-side direction of the mounting holes 62 by the inner side of the inner second panel P2 rotating in the direction of the both side edges 203, 204 of the support plates 2 by the biasing force of the coil springs 5 between the claw plates 3 (the elastic restoring force of the coil springs 5) and protruding outward from the both side edges 203, 204. Here, as shown in fig. 3, in the panel fixing member F, the rotation center of the claw plate 3 is provided near the third surface portion 303 on the first surface portion 301 side, and the second surface portion 302 of the claw plate 3 is formed in an arc shape having a center positioned closer to the first surface portion 301 and closer to the fourth surface portion 304 than the rotation center of the claw plate 3, so that the arc-shaped portion of the claw portion 31 is pushed out toward the edge of the mounting hole 62 and bites into each edge of the mounting hole 62 in the short-side direction as the claw portion 31 is rotated outward, as shown in fig. 7, of the claw plate 3. As a result, as shown in fig. 6 (3), the pair of support plates 2 are pulled from the mounting hole 61 of the first panel P1 to the mounting hole 62 of the second panel P2, the flange 11 of the mounting plate 1 abuts against the entire periphery of the mounting hole 61 of the first panel P1, and the two panels P1 and P2 are fastened and joined between the mounting plate 1 and the pair of claw plates 3.
As described above, the panel fixing member F according to the present invention includes: a mounting plate 1, the mounting plate 1 having a mounting surface larger than the first mounting hole 61 of the first panel P1; a pair of support plates 2, each of the support plates 2 having a flange 11 formed around the entire periphery of the mounting surface of the mounting plate 1, being inserted into the first mounting hole 61 of the first panel P1 and the second mounting hole 62 of the second panel P2, and protruding from the mounting surface of the mounting plate 1 in parallel with each other; a pair of claw plates 3, the pair of claw plates 3 having a rotation center on the first surface portion 301 side, the second surface portion 302 being formed in an arc shape, and portions from the second surface portion 302 to the third surface portion 303 being claw portions, the pair of claw plates 3 being arranged so as to be rotatably supported between the pair of support plates 2 via a pair of shafts 4 inserted on both sides on the protruding end 201 side of the pair of support plates 2, respectively, and the claw portions 31 being capable of being extended and retracted from both side edge portions of the pair of support plates 2; and a coil spring 5 as a spring member, wherein the coil spring 5 is a spring member, and in a normal state, the pair of claw plates 3 are pivotally biased by the coil spring 5 so as to protrude from both side edge portions 203, 204 of the pair of support plates 2, the pair of support plates 2 and the pair of claw plates 3 are passed through the first mounting hole 61 of the first panel P1 and the second mounting hole 62 of the second panel P2 together by one push, and the pair of claw plates 3 are locked to the edge portion of the second mounting hole 62 of the second panel P2, and therefore, the panel holder F can be passed through and locked to the mounting holes 61, 62 of the two panels P1, P2 by one push without using a tool, and therefore, the mounting work is simplified, and the two panels P1, P2 can be joined more quickly and easily than in the conventional case.
Further, in the panel fixing member F described above, there are also the following advantages.
(1) The rotation center of each claw plate 3 is provided near the third surface portion 303 on the first surface portion 301 side of the claw plate 3, and the second surface portion 302 is formed in an arc shape having a center positioned closer to the first surface portion 301 and closer to the fourth surface portion 304 than the rotation center of the claw plate 3, so that, when the claw plate 3 is pushed once through the mounting holes 61 and 62 of the two panels P1 and P2 after the panel fixing member F passes through the mounting holes 61 and 62, the arc-shaped portion of the claw portion 31 can be pushed out toward the edge of the mounting hole 62 and can be caused to bite into the edge of the mounting hole 62 as the claw portion 31 is rotated outward. Thus, the pair of support plates 2 can be pulled from the first mounting hole 61 of the first panel P1 to the mounting hole 62 of the second panel P2, the flange 11 of the mounting surface of the mounting plate 1 can be brought into contact with the entire periphery of the first mounting hole 61 of the first panel P1, and the two panels P1 and P2 can be fastened and joined between the mounting plate 1 and the pair of claw plates 3. Therefore, even if there is a slight deviation in the plate thickness of the two panels P1, P2, the two panels P1, P2 can be joined reliably without play.
(2) The third surface portion 303 of each claw plate 3 is formed in parallel with the both side edge portions 203, 204 of the support plate 2, a part of the first surface portion 301 of each claw plate 3 on the side of the third surface portion 303 is formed in an arc shape having a center of a circle placed at the rotation center of the claw plate 3, the remaining part of the first surface portion 301 on the side of the fourth surface portion 304 is formed to be inclined symmetrically to the third surface portion 303 with the rotation center of the claw plate 3 as a symmetric center, and the fourth surface portion 304 of each claw plate 3 is formed in a direction parallel to the third surface portion 303 or slightly opened from the parallel direction, so that the pair of claw plates 3 can be arranged such that only the claw portions 31 can be extended and retracted from the both side edge portions 203, 204 of the support plate 2 inside the pair of square support plates 2.
Further, on the mounting surface of the mounting plate 1, the pair of stoppers 21 are formed in a stepped manner on the side of both side edge portions 203, 204 between the pair of support plates 2, and the end portion on the side of the fourth surface portion 304 of the second surface portion 302 of each claw plate 3 is provided with the convex rotation restricting portion 32 engageable with each stopper 21 of the mounting plate 1, so that each claw plate 3 can be reliably prevented from flying out of each support plate 2, and the claw portion 31 of each claw plate 3 can be reliably extended and retracted from both side edge portions 203, 204 of each support plate 2.
Further, the cylindrical hole 33 is formed in the other side edge portion 304 of each claw plate 3, and the coil spring 5 is used as a spring member, and the coil spring 5 is interposed between the claw plates 3 so that both ends thereof are held in the hole 33 of each claw plate 3, whereby the respective claw plates 3 can be reliably urged to pivot in the directions of the both side edge portions 203, 204 of the respective support plates 2 with a simple structure.
In this case, the hole 33 of each claw plate 3 is formed at a predetermined angle with respect to the fourth surface portion 304 so that the coil spring 5 can be deformed into an arc shape protruding toward the mounting plate 1 side when the claw portions 31 of the pair of claw plates 3 protrude from the both side edge portions 203, 204 of the support plate 2 before and after the pair of support plates 2 and the pair of claw plates 3 are passed through the mounting holes 61, 62 of the two panels P1, P2 together, and the portion 331 of the inner peripheral surface of the hole 33 on the second surface portion 302 side is formed with an inclination of a predetermined angle so that the diameter is gradually enlarged from the back side toward the opening side of the hole 33 so that the coil spring 5 can be guided to be deformed into an arc shape protruding toward the opposite side to the mounting plate 1 when the claw portions 31 of the pair of claw plates 3 are retracted inside the both side edge portions 203, 204 of the support plates 2 while the pair of support plates 2 and the pair of claw plates 3 are passed through the mounting holes 61, 62 of the two panels P1, P2 together, therefore, the coil spring 5 can be deformed to expand and contract, and the claw portions 31 of the pair of claw plates 3 can be reliably and smoothly extended and retracted from the both side edge portions 203 and 204 of the pair of support plates 2.
(3) The mounting plate 1 is formed of a rectangular plate larger than the first mounting hole 61 of the first panel P1, the pair of support plates 2 are formed in a rectangular shape having a predetermined length that can pass through the two mounting holes 61 and 62 in a size that can be fitted into the mounting holes 61 and 62 of the two panels P1 and P2, respectively, and the mounting holes 61 and 62 of the two panels P1 and P2 are opened in the rectangular shape, respectively, so that the mounting holes 61 and 62 of the two panels P1 and P2 can be formed in a simple shape, and the cost required for drilling can be reduced.
In the above embodiment, the coil spring 5 is used as the spring member and the coil spring 5 is interposed between the pair of claw plates 3, but a torsion spring or a leaf spring may be used as the spring member and interposed between each claw plate 3 and each support plate 2. This also provides the same effects as those of the above embodiment.
The panel fastener F is used for joining two panels, but the present invention can be applied to a case where another member is present between two panels, a case where three or more panels are overlapped and joined, and the present invention is not limited to the case of joining only two panels.
