Description
- The present invention relates to a fastener fastening tool which can prevent a loaded fastener from coming off by a reaction force at a cutoff time of a weakened portion.
- The present applicant has already proposed a fastener (Patent Document 1) which expands a diameter of a female member by pushing a male member into the female member, or a rivet fastening air tool (Patent Document 2).
- Patent Document 1: Japanese Unexamined Patent Publication No. 2010-43728
- Patent Document 2: Japanese Unexamined Patent Publication No. 2010-29939
- There has been no fastener fastening tool, however, there has been a demand for the tool. Namely, the aforementioned rivet fastening air tool is loaded by tearing off the thin-walled weakened portion of a rivet (see paragraph [0102] of the Patent Document 2).
- However, a fastener differs from the rivet used for the rivet fastening air tool, in which the structure is complicated, and increases in size, so that a wall thickness of the weakened portion also increases to be comparatively thick, and it is difficult to tear off. Accordingly, the weakened portion has been required to be cut off.
- In the fastener fastening tool, however, there has been the possibility for the already loaded fastener to come off by the reaction force at the cutoff time of the weakened portion.
- Thus, the present invention is made in view of the aforementioned demand, and an object thereof is to be capable of preventing the loaded fastener from coming off by the reaction force at the cutoff time of the weakened portion.
- The present invention is made in order to achieve the aforementioned object, and the present invention has the following characteristics.
- First, a fastener comprises the following structure.
- (1) Female Member
- A female member includes a flange portion and a leg portion hanging from the flange portion.
- (2) Male Member
- A male member can expand an outer diameter of the leg portion by pushing the male member toward the leg portion from the flange portion.
- Incidentally, in a section of “Best Modes of Carrying out the Invention”, the fastener will be explained as an example of a fastener wherein the male member is screwed into a hoisting member of the female member, thereby expanding a diameter of the female member through the hoisting member, i.e., a “hoisting-type screw grommet”. However, the fastener is not limited to the above. The fastener may be, for example, a general fastener wherein the hoisting member is omitted, and the male member is directly screwed into the female member, i.e., a “screw grommet”; a fastener wherein the male member is pressed only at a fastening time so as to expand the diameter of the female member, and the male member is twisted and turned at a releasing time so as to restore the female member, i.e., a “scrivet”; a fastener which does not include a screw structure, expands the diameter of the female member by a first pressing, and restores the female member by a second pressing so as to be capable of releasing a fastened state, i.e., a “push-push rivet”; or a fastener which also does not include the screw structure, expands the diameter of the female member by pressing the male member only at the fastening time, and restores the female member by pulling the male member at the releasing time so as to be capable of releasing the fastened state, i.e., a “push pull rivet”.
- Secondly, by connecting both adjacent flange portions through a weakened portion by facing the leg portion in the same direction, the fastener is structured as a fastener row wherein a plurality of fasteners is linked together like beads.
- Thirdly, a fastener fastening tool comprises the following structure.
- (3) Supply Channel
- A supply channel is for supporting the fastener row slidably in a row.
- (4) Transfer Mechanism
- A transfer mechanism is for transferring the fastener row supported in the supply channel in one direction.
- (5) Cutoff Mechanism
- A cutoff mechanism is for cutting off the weakened portion of the fastener row supported in the supply channel.
- (6) Loading Member
- A loading member is for holding one fastener which has been cut off by the cutoff mechanism in a loading portion which is located in front in a transfer direction of the transfer mechanism, and is positioned by abutting against the front-most row of the supply channel.
- (7) Slide Mechanism
- A slide mechanism is for moving the loading member forward and backward.
- (8) Push-in Mechanism
- A push-in mechanism is for expanding the outer diameter of the leg portion by pushing the male member of the fastener loaded in the loading member.
- Fourthly, the cutoff mechanism cuts off the weakened portion of the fastener in a second row, positioned in a next row thereof by counting the fastener in the front-most row as the first row, and in subsequent rows.
- The present invention may have the following characteristic.
- First, between the female member and the female member, there is respectively formed either one of a male screw portion or a female screw portion wherein the male screw portion is screwed in.
- Secondly, the push-in mechanism screws the male member in when the male member is pushed in.
- Consequently, a tool, which fits into the fastener expanding the diameter of the female member by screwing the male member toward the female member, can be provided.
- The present invention may have the following characteristic.
- Namely, the cutoff mechanism cuts off the weakened portion between the fastener in the first row and the fastener in the second row. Consequently, the cutoff mechanism can be disposed in an appropriate position.
- The present invention may have the following characteristic.
- Namely, in the leg portion, there comprises the hoisting member which can expand the outer diameter of the leg portion by advancing an inside of the leg portion toward the flange portion when the male member is screwed in. Consequently, a tool, which fits into the fastener comprising the hoisting member, can be provided.
- Due to the aforementioned structure, the present invention can prevent the loaded fastener from coming off by the reaction force at the cutoff time of the weakened portion. Also, by cutting off the weakened portion before loading, the reaction force due to a cutoff is not allowed to act at a loading time so as to be capable of reliably loading the fastener.

FIG. 8 andFIG. 9 , the cutter, which is thecutoff mechanism 83, is moved forward, and cuts off the weakenedportion 41 in between thefastener 20 in the first row and thefastener 20 in the second row by counting the front-most row of thesupply channel 81 as the first row. Incidentally, the cutter is moved backward again after being moved forward so as to move away from thesupply channel 81. - Fourthly, the
fastener 20, in which the weakenedportion 41 has been cut off, is transferred to theloading portion 51 from the front-most row of thesupply channel 81 by thetransfer mechanism 82. As shown inFIG. 3 andFIG. 6 , theflange portion 110 of thefemale member 100 thereof is held by the loadingmember 52. - Fifthly, as shown in
FIG. 1 andFIG. 4 , the loadingmember 52 is moved forward by the slide mechanism 53 so as to protrude theleg portion 120 of thefemale member 100 from theend cylinder 57. - Sixthly, as shown in
FIG. 13 , theleg portion 120 is inserted into the attachment holes 30 a and 30 b of the two sheets ofpanels - Seventhly, by operating the
first operation portion 70, the push-in mechanism 54 is driven so as to rotate thehead portion 210 of themale member 200. When thehead portion 210 rotates, due to an engagement between themale screw portion 221 of theaxis portion 220 and thefemale screw portion 142 of the hoistingmember 140, as shown inFIG. 14 , the hoistingmember 140 advances the inside of theleg portion 120 toward theflange portion 110, so that theleg portion 120 expands the diameter at a back side of thepanel 31. Consequently, through thefastener 20, the two sheets ofpanels - Eighthly, when the
tool 10 is pulled away from thepanel 30, since a fastening force between thepanel 30 and thefastener 20 surpasses a holding force of theloading member 52, as shown inFIG. 5 andFIG. 7 , thefastener 20 comes off from the loadingmember 52. Incidentally, when thesecond operation portion 71 is operated in the second place, the loadingmember 52 moves backward by the slide mechanism 53, and stands by at theloading portion 51. - (Fastener 20)
- Next, using
FIGS. 10 to 14 , details of thefastener 20 will be explained. - The
fastener 20 includes thefemale member 100 comprising theflange portion 110 and theleg portion 120. In an illustrated example, thefastener 20 is structured by combining themale member 200, which produces the aforementioned expansion by the aforementioned forward-screwing operation, with suchfemale member 100 beforehand. In the illustrated example,such fastener 20 is attached to thepanels leg portion 120 by the forward-screwing operation of suchmale member 200 after theleg portion 120 of thefemale member 100 is inserted relative to the attachment holes 30 a and 30 b formed having a size wherein theflange portion 110 of thefemale member 100 can not enter in, and by sandwiching thepanels leg portion 120 and theflange portion 110 from two sides (or front and back, or inside and outside, or up and down, or right and left). In the illustrated example, in order to provide such expansion function to thefemale member 100, suchfemale member 100 is made of plastic. Themale member 200 comprises thehead portion 210, and theaxis portion 220 having themale screw portion 221, and typically, themale member 200 is made of plastic or metal. - (Male Member 200)
- In the illustrated example, such
male member 220 is structured by thehead portion 210 forming a circular disk shape, and theaxis portion 220 wherein anaxis base portion 222 is integrally connected in the center of one face side of thehead portion 210. On the other face side ofsuch head portion 210, there is formed theoperating hole 211 in which the end of the tool such as the driver and the like is housed. - (Female Member 100)
- On the other hand, in the illustrated example, the
female member 100 is structured in such a way that theflange portion 110 has a circular disk shape, and that theleg portion 120 has a hollow angular cylinder shape. Theleg portion 120 is structured thinner than an outer diameter of theflange portion 110. Theleg portion 120 integrally connects one end of a cylinder thereof in the center of one face side of theflange portion 110. In theflange portion 110, there is formed a through-bore 111 communicated with the inside of theleg portion 120 connected to theflange portion 110 in the aforementioned manner. On the other face side of theflange portion 110, there is formed a circling risingportion 112 by positioning such through-bore 111 on an inner side. An inner diameter of the circling risingportion 112 is approximately equal to a diameter of thehead portion 210 of themale member 200, and themale member 200 is combined with thefemale member 100 in such a way as to house thehead portion 210 inside the circling risingportion 112, and as to insert theaxis portion 220 thereof into theleg portion 120 through the through-bore 111 of theflange portion 110. - The
leg portion 120 of thefemale member 100 is divided by the hoistingmember 140 and a legmain body 130. The hoistingmember 140 is structured in such a way as to be moved to theflange portion 110 side by the forward-screwing operation of themale member 200 which has been inserted from theflange portion 110 side. The legmain body 130 is located between such hoistingmember 140 and theflange portion 110, and is structured in such a way as to be expanded by inserting the hoistingmember 140, which is moved to theflange portion 110 side by the forward-screwing operation, to the inner side. - (Leg Main Body 130)
- In the illustrated example, the leg
main body 130 is structured in such a way that both inner and outer faces have an approximately square outline in a cross-sectional surface in a direction orthogonal to an axis line x (FIG. 12( a)/a center line) of theleg portion 120. The inner side of the legmain body 130 is made wider than a thickness of theaxis portion 220 of themale member 200. Also, at four corners of such legmain body 130, there are respectively formedslits 131 along the axis line x of theleg portion 120. The legmain body 130 is partitioned into four sheets ofplate pieces 132 bysuch slit 131 ranged between a cylinder oneend 133 positioned on a hoistingmember 140 side in such legmain body 130, and a cylinderother end 134 positioned on a connecting side to theflange portion 110. The through-bore 111 of theflange portion 110 of thefemale member 100 has a rectangular hole which follows an outline of the inner side of such legmain body 130. Incidentally, in the illustrated example, insuch flange portion 110, there are formedbrunched split grooves 113 communicated with a pair of corner portions, which is in an opposing position of the through-bore 111, and continuing to a formation position of the circling rising portion 112 (FIG. 12( d)). - (Hoisting Member 140)
- The hoisting
member 140 comprises a throughhole 141 of theaxis portion 220 of themale member 200 on an inner side. In the illustrated example, in the throughhole 141, there is formed thefemale screw portion 142 corresponding to themale screw portion 221 of theaxis portion 220 of themale member 200. In the illustrated example, in a state before the forward-screwing operation, themale member 200 positions anaxis end portion 223 side thereof inside the hoistingmember 140 by engaging themale screw portion 221 with thefemale screw portion 142 of the hoistingmember 140. If thefemale screw portion 142 is formed on the inner side of the hoistingmember 140 in the above-mentioned manner, by the aforementioned forward-screwing operation, the hoistingmember 140 can be smoothly inserted into the inner side of the legmain body 130. Aside from the illustrated example, in a case wherein thefemale screw portion 142 is not formed on the inner side of the hoistingmember 140 in the above-mentioned manner, themale member 200 is not combined with thefemale member 100 beforehand. Then, from a state wherein theleg portion 120 of thefemale member 100 has been inserted into the attachment holes 30 a and 30 b of thepanels male portion 200 as a tapping screw is screwed into thefemale member 100. By the screwing (forward-screwing) of themale member 200, the hoistingmember 140 is inserted into the inner side of the legmain body 130 so as to be attached to thepanels main body 130. - In the illustrated example, in the cross-sectional surface in the direction orthogonal to the axis line x of the
leg portion 120, an outer face of the hoistingmember 140 is structured in such a way as to have an approximately square outline shape in any position in a direction of the axis line. Namely, the hoistingmember 140 comprisesouter faces 143 respectively corresponding to the four sheets ofplate pieces 132 of the legmain body 130 divided by theslits 131. Also, the hoistingmember 140 includes a cylinder oneend 145 having an approximately equal thickness to a width of the inner side of the legmain body 130, and inserted into an inner side of the cylinder oneend 133 of the legmain body 130; and a cylinderother end 146 having an approximately equal thickness to a thickness of an outer side of the legmain body 130. In the illustrated example, such hoistingmember 140 and the legmain body 130 are connected and joined through a thin-walled connectingportion 150 which is installed between theouter face 143 of the cylinder oneend 145 of the hoistingmember 140 and aninner face 136 of the cylinder oneend 133 of the leg main body 130 (FIG. 13 ). Also, in the illustrated example, outside the hoistingmember 140, there are formed rib-like guide portions 147 along the axis line x of theleg portion 120 respectively in a pair of corner portions which is in an opposing position among four corner portions of the hoistingmember 140. One end of theguide portion 147 is positioned on theflange portion 110 side of thefemale member 100 rather than the cylinder oneend 145 of the hoistingmember 140. In the state before the forward-screwing operation, one end of theguide portion 147 has been inserted into theslit 131 of the legmain body 130. Then, by such forward-screwing operation, when the hoistingmember 140 is moved in a direction of being inserted further into the inside of the legmain body 130, i.e., when the hoistingmember 140 is moved toward theflange portion 110 side of thefemale member 100, theguide portion 147 is guided to theslit 131 so as to be moved along theslit 131. - Then, in the embodiment, at a time of the aforementioned expansion of the leg
main body 130 of theleg portion 120 of thefemale member 100, theouter face 143 of the hoistingmember 140, which has contact with theinner face 136 of anexpansion portion 135 of the legmain body 130, is structured in such a way as to have a shape following theinner face 136 of theexpansion portion 135. Specifically, at the time of the expansion of the legmain body 130 ofsuch leg portion 120, theouter face 143 of the hoistingmember 140, which has contact with theinner face 136 of theexpansion portion 135 of the legmain body 130, becomes a curved face 144 having a curvature following a curvature of the inner face of the expansion portion 135 (FIG. 14 ). In the illustrated example, fourouter faces 143 of the hoistingmember 140 respectively include the curved faces 144 curved in a direction of gradually expanding the hoistingmember 140 as the hoistingmember 140 goes toward a cylinderother end 146 side from a cylinder oneend 145 side thereof. - (Usage Method of the Fastener 20)
- After the
leg portion 120 is inserted into the attachment holes 30 a and 30 b of thepanels leg portion 120 of thefastener 20, when themale member 200 is operated to be screwed forward, i.e., when themale member 200 is operated in a direction of being inserted further than theflange portion 110 side of thefemale member 100 while themale member 200 is rotating, the hoistingmember 140 is moved in a direction of approaching theflange portion 110 side. Accordingly, by being pushed from the inside by the hoistingmember 140 which is moved in the aforementioned manner, the legmain body 130 is expanded. Thereby, thefastener 20 is fastened to thepanels panels flange portion 110 thereof and theexpansion portion 135. In the fastened state, theouter face 143 of the hoistingmember 140 has the shape following theinner face 136 of theexpansion portion 135 of the legmain body 130, so that in order to prevent a gap between bothfaces faces leg portion 120 with the faces (FIG. 14 ). Thereby, even in a case wherein a force in a direction of crossing such axis line x acts on thepanels panels panels fastener 20, one of thepanels panels such panels axis base portion 222 of theaxis portion 220 of themale member 200 is structured slightly larger compared to a formation portion of themale screw portion 221. In the fastened state, a gap between the legmain body 130 and theaxis base portion 222 is reduced so as to contribute to a reduction of the wobbling. - In the illustrated example, first, the
leg portion 120 of thefemale member 100 is inserted into the attachment holes 30 a and 30 b of thepanels FIG. 13 ). Next, when themale member 200 is operated to be screwed forward, thehead portion 210 thereof is caught on theflange portion 110 of thefemale member 100, so that themale member 200 itself does not move in the direction of being inserted further than theflange portion 110. However, the hoistingmember 140 receives a moving force in the direction of approaching theflange portion 110. The hoistingmember 140 is prevented from turning associated with themale member 200 by theguide portion 147, and only a movement by being guided to theslit 131 is allowed, so that due to the forward-screwing operation of themale member 200, the thin-walled connectingportion 150 is broken. Also, the hoistingmember 140 is gradually moved toward theflange portion 110 side, so that the legmain body 130 is expanded (FIG. 14 ). - The overall
female member 100 may not have to be made of plastic, andsuch hoisting member 140 can be structured by metal. In that case, without providing the thin-walled connectingportion 150 connecting the hoistingmember 140 and the legmain body 130, bothportions member 140 is made of metal, it is difficult for a situation, wherein themale screw portion 221 of themale member 200 has crushed thefemale screw portion 142 of the hoistingmember 140 at a time of the forward-screwing operation, to occur. Accordingly, by sufficiently moving the hoistingmember 140 to theflange portion 110 side by such forward-screwing operation, the legmain body 130 can be appropriately expanded. Also, a rigidity of theguide portion 147 formed insuch hoisting member 140 can be enhanced. Even in a case wherein thefemale member 100 is downsized, with theguide portion 147 guided to theslit 131 at the time of the forward-screwing operation, the hoistingmember 140 can be reliably prevented from turning associated with themale member 200. - The fastened state of the
fastener 20 tosuch panels male member 200. When themale member 200 is operated to be screwed backward from a state ofFIG. 14 , since the hoistingmember 140 is fitted into the inner side of the legmain body 130 in a state wherein the legmain body 130 is expanded, themale member 200 gradually slips out of the inside of thefemale member 100. When themale member 200 is pushed into thefemale member 100 from a state wherein themale member 200 has been screwed backward for a dimension portion in which the hoistingmember 140 has been moved to theflange portion 110 side by the aforementioned forward-screwing operation, the hoistingmember 140 is slipped out and returned to a position before the forward-screwing operation from the legmain body 130, and an expanded state of the legmain body 130 is released, so that the fastened state of thefastener 20 to thepanels - All contents of the specification, claims, drawings, and abstract of Japanese Patent Applications No. 2010-137020 filed on Jun. 16, 2010 are cited in their entireties herein and are incorporated as a disclosure of the specification of the present invention.
