Technical Field

The present invention relates to a locking tool for mounting a sheet-like mounting member such as a lower cover plate to a mounted member such as an automobile panel on which a stud such as a stud bolt is erected. More specifically, the present invention relates to a stud retainer for attaching an attachment member to an attached member by locking a retainer holding the attachment member to a stud standing on the attached member.

Background

Generally, a locking member is used for attaching a sheet-like attachment member such as a lower cover to an attachment target member such as an automobile panel. In order to attach a wide sheet-like attachment member such as a lower cover plate to a panel, studs are fixed to a plurality of predetermined positions of an attached member by welding or the like, and attachment holes into which the studs are fitted are formed at predetermined positions in the attachment member. A stud erected on the member to be mounted is inserted through the mounting hole of the mounting member, and the nut is engaged with the stud protruding from the mounting hole of the mounting member. Thus, the mounting member is mounted to a mounted member such as an automobile panel.

In order to facilitate the mounting work of the mounting member, the following stud retainer is known: the mounting member is held from both sides by the engaging member formed of two members, and in this state, the mounting member is mounted by fitting the stud into the stud-fitting hole of the engaging member.

Patent document 1 discloses a fixing tool (a stud retainer) including a first ferrule and a second ferrule. The first ferrule has an inner tube portion, a flange formed at one end of the inner tube portion, and a locking claw inside the inner tube portion. The second ferrule has an outer tube section and a flange formed at one end of the outer tube section. The fastener of patent document 1 is attached by sandwiching a sheet-like attachment member between a flange of a first ferrule and a flange of a second ferrule. The mounting member is mounted to a mounting target member such as an automobile panel by engaging the fixing members with a plurality of pegs erected on the mounting target member.

Fig. 22 shows a fixing member 1' of patent document 1. The anchor 1' is constituted by a first ferrule 2 made of hard synthetic resin which is integrally molded, and a second ferrule 3 made of hard synthetic resin which is integrally molded. The first ferrule 2 includes an inner tube portion 2b and a flange 2a formed at one end of the inner tube portion 2 b. The second ferrule 3 has an outer tube portion 3b and a flange 3a formed at one end of the outer tube portion 3 b.

The inner tube portion 2b of the first ferrule 2 is inserted into the mounting hole 9 of the sheet-shaped mounting member 5, and the inner tube portion 2b of the first ferrule 2 is inserted into the outer tube portion 3b of the second ferrule 3. A mounting member 5 is interposed between the flange 2a of the first ferrule 2 and the flange 3a of the second ferrule 3, and the first ferrule 2 and the second ferrule 3 are coupled to each other. When a stud 7 standing on a mounting member 6 such as an automobile panel is inserted into a stud insertion hole of the anchor 1', the locking claw 4 of the first clip 2 engages with the screw of the stud 7 and is locked, and the mounting member 5 is mounted on the mounting member 6.

A hexagonal hole 8 is formed in the center of the flange of the first ferrule 2, and a hexagonal wrench is engaged with the hexagonal hole 8 and rotated, whereby the fastener 1' can be more tightly coupled to the stud 7 or detached from the stud 7.

The retainer of patent document 1 does not have a tapered portion for fitting the peg into the bottom surface of the peg fitting hole of the first ferrule. Therefore, when the peg is inserted into the peg attachment hole, the peg is not guided by the peg attachment hole, and therefore, the position of the peg needs to be inserted in alignment with the peg attachment hole.

Patent document 2 discloses a mounting member that facilitates positioning of a mounting member. A stud is projected from the member to be attached, the stud is inserted into the attachment hole of the attachment member, and the attachment member is locked to the screw portion on the outer peripheral surface of the stud. The attachment includes a ferrule including an elastic portion and a locking portion, and a guide member for guiding the plug to the ferrule, wherein the elastic portion abuts against the mounting hole of the mounting member, and the locking portion is locked to the screw portion of the plug.

When the pin is pressed into the mounting member, the pin is inserted into the locking portion in a state where the elastic portion expands and contracts while sliding along the guide member, and the axis of the pin coincides with the locking portion. Thus, the locking portion of the attachment is locked to the screw portion of the stud.

In the attachment of patent document 2, even when the axis of the peg is disposed at a position offset from the center of the mounting hole, the peg slides along the guide hole and is inserted into the locking portion by pressing the tip of the peg against the tapered surface of the guide hole of the guide member.

However, the guide member of patent document 2 is thin-plate-shaped, and the range in which the peg can be guided is limited.

In addition, the elastic part enters the mounting hole of the mounting component, and the elastic part stretches and contracts to enable the axis to be consistent with the stud. The mounting member cannot move easily in a direction at right angles to the axis. Therefore, if the position of the peg is deviated, it is difficult to insert the peg into the locking portion.

The prior art structure for guiding the front end of the peg arranged on the hoop has the following defects: if the range in which the ferrule can guide the peg is increased, the force with which the first ferrule and the second ferrule sandwich the attachment member is increased when the peg is inserted, and the slidability of the peg in the lateral direction is impaired.

Therefore, when mounting a mounting member such as a lower cover plate to a mounting member such as an automobile panel on which a peg is erected, a peg fastener capable of guiding the peg over a wide range without impairing the slidability at the time of guiding the peg is desired.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. A stud retainer 1 according to an embodiment of the present invention includes a first integrally molded rigid synthetic resin ferrule 10 shown in fig. 1 to 8 and a second integrally molded rigid synthetic resin ferrule 30 shown in fig. 9 to 16.

(first hoop)

The first ferrule 10 is explained with reference to fig. 1 to 8. Fig. 1 is a perspective view of first ferrule 10 of peg catch 1 in accordance with one embodiment of the present invention. Fig. 2 is a perspective view of the first cuff 10 viewed from another direction. Fig. 3 is a plan view of the first ferrule 10, fig. 4 is a front view, fig. 5 is a bottom view, and fig. 6 is a right side view. Fig. 7 is an a-a line end view of the first ferrule 10 of fig. 3. Fig. 8 is a B-B line end view of the first ferrule 10 of fig. 3.

As shown in fig. 4 and 6, the first ferrule 10 has a first flange 11 at the upper end. The first flange 11 has a disc shape with a large diameter. As shown in fig. 3, 8 flange ribs 12 radially extend from the upper surface of the first flange 11. The flange rib 12 reinforces the thin-walled first flange 11. The lower surface of the first flange 11 is planar.

As shown in fig. 4, the first band 10 is adjacent to the first flange 11 and has an inner cylindrical portion. The inner cylinder includes a large-diameter inner cylinder 14, a small-diameter inner cylinder 15, and an inner cylinder end 16.

The large-diameter inner cylindrical portion 14 extends from the first flange 11 in the axial direction along the central axis.

The first ferrule 10 is adjacent to the large-diameter inner tube portion 14, and has a small-diameter inner tube portion 15 having a smaller diameter than the large-diameter inner tube portion 14. As shown in fig. 8, a stepped portion having a step in the right-angle direction is formed between the large-diameter inner cylindrical portion 14 and the small-diameter inner cylindrical portion 15. The small-diameter inner cylindrical portion 15 is formed of two portions extending in the circumferential direction around the central axis, and a window is provided between the two portions. A locking claw 25 described later is formed in the window.

The first ferrule 10 is adjacent to the small-diameter inner tube portion 15 and has an inner tube portion end 16. A stepped portion having a step in the right-angle direction is formed between the small-diameter inner tube portion 15 and the inner tube end portion 16. The outer diameter of the inner cylindrical portion end 16 is substantially equal to the outer diameter of the large-diameter inner cylindrical portion 14. The inner cylinder end 16 has a short length in the height direction, and the upper and lower surfaces are flat. As will be described later, the inner tube portion end 16 functions as a stopper on the first band 10 side.

As shown in fig. 8, a through hole is formed along the central axis from the first flange 11 of the first ferrule 10 to the inner cylinder end 16. The through hole is a hole for passing the peg 70 therethrough. The through hole is a large-diameter hole 21 having a large inner diameter inside the first flange 11 and the large-diameter inner cylindrical portion 14. Inside the large- diameter hole 21, 4 protrusions 23 extend in the height direction from the upper surface of the first flange 11 to the end of the large-diameter hole 21. The tip of a tool such as a screwdriver can be pressed against the protrusion 23 to rotate the first ferrule 10.

As shown in fig. 8, the through hole is a small-diameter hole 22 having a small inner diameter inside the small-diameter inner tube portion 15 and the inner tube end portion 16. The small diameter hole 22 has an inner diameter equal to the distance between the protrusions 23 facing the inside of the large diameter hole 21.

As shown in fig. 6 and 7, a pair of locking claws 25 extend upward from the inner cylinder end 16 at a circumferential position where the small diameter inner cylinder 15 is not present. The distal end portion of the locking claw 25 is bent inward to become a locking claw distal end portion 25 a. The edge of the locking claw tip 25a is concave in shape to match the outer diameter of the external thread of the peg 70.

The locking claw distal end portions 25a of the pair of locking claws 25 are different in position in the height direction, and can correspond to the difference in the left-right height of the thread portion of the male thread of the peg 70.

Only one locking claw tip portion 25a is formed in one locking claw 25. The locking claw 25 is small in size in the height direction, and the height of the entire plug fastener 1 can be reduced.

A pair of flange holes 13 are formed at radially outward facing positions of the large-diameter inner tube portion 14 of the first flange 11. The flange hole 13 is provided to allow a tool to engage with the flange hole 13 to rotate and detach the first ferrule 10 and the second ferrule 30.

(second hoop)

The second cuff 30 is explained with reference to fig. 9 to 16. Fig. 9 is a perspective view of second ferrule 30 of peg catch 1 in accordance with an embodiment of the present invention. Fig. 10 is a perspective view of the second cuff 30 viewed from another direction. Fig. 11 is a plan view of the second ferrule 30, fig. 12 is a front view, fig. 13 is a bottom view, and fig. 14 is a right side view. Fig. 15 is an end view a-a of fig. 11 of the second ferrule 30. Fig. 16 is a B-B line end view of fig. 11 of the second ferrule 30.

The second ferrule 30 has a second flange 31 of large diameter at the upper end. The upper surface of the second flange 31 is a surface tangent to the lower surface of the mounting member 51.

An elastic edge 32 extending obliquely upward is formed on the outer edge of the second flange 31. The elastic edge portion 32 elastically presses the lower surface of the mounting member 51 toward the first flange 11 of the first ferrule 10.

As shown in fig. 9 and 11, 4 elongated flange holes 33 extending in the circumferential direction are formed around the center axis of the second ferrule 30 of the second flange 31. The flange holes 33 facilitate the elastic deflection of the elastic rim 32.

The elastic edge portion 32 and the portion of the second flange 31 inside the flange hole 33 have rigidity and are less elastically deformed.

The second ferrule 30 has an outer barrel portion 35 that abuts the second flange 31 and extends downwardly.

An outer cylinder housing 36 is formed inside the outer cylinder 35. The inner diameter of the outer cylinder housing 36 is larger than the outer diameters of the large-diameter inner cylinder portion 14 and the inner cylinder end portion 16 of the first ferrule 10, and the inner cylinder portion of the first ferrule 10 can be mounted therein. As shown in fig. 9, the bottom surface of the outer cylinder housing 36, i.e., the housing bottom surface 37, is a flat surface. As will be described later, the receiving portion bottom surface 37 functions as a stopper on the second ferrule 30 side.

A circular bottom hole 41 is formed in the center of the bottom surface 37 of the housing portion. The bottom hole 41 has an inner diameter larger than the outer diameter of the peg 70 to allow the peg 70 to pass through.

As shown in fig. 14, a window is formed in the outer tube portion 35 at a position facing the central axis. A pair of engagement claws 38 is formed in the window. The engaging claw 38 extends downward in the window from the lower surface of the second flange 31. A pair of engagement claw distal end portions 38a of the engagement claws 38 extend inward of the outer tube housing portion 36. The distance between the pair of engagement claw distal ends 38a of the engagement claws 38 is smaller than the outer diameter of the inner tube portion end 16 of the first ferrule 10. As shown in fig. 15, the engaging claw bottom surface 38b of the bottom surface of the engaging claw 38 is a flat surface.

When the inner cylindrical end 16 of the first ferrule 10 is inserted into the outer cylindrical housing 36 of the second ferrule 30, the pair of engagement claw distal ends 38a are engaged with the inner cylindrical end 16 and are not disengaged therefrom.

As shown in fig. 12 and 16, the outer surface and the inner surface of the lower side of the outer tube portion 35 are both inclined surfaces 42 that conically expand downward. The lower surface of the ramp portion 42 is a guide surface 42a that guides the peg 70 to the bottom hole 41.

In one embodiment, 6 outer cylinder ribs 43 are formed on the outer side of the outer cylinder portion 35 and the inclined surface portion 42. The outer cylinder rib 43 extends in the lateral direction and the height direction, and reinforces the outer cylinder portion 35 and the slope portion 42. The shape and number of the outer cylindrical ribs 43 are not limited to those shown here.

Fig. 17 is a perspective view of the peg catch 1 assembled from the first ferrule 10 and the second ferrule 30. Fig. 18 is a top view of peg catch 1. Fig. 19 is a front view of a state in which the mounting member 51 is mounted to the mounted member 61 by the peg catcher 1.

In the detailed description of the present invention, the top and bottom in fig. 19 will be referred to as the top and bottom direction, and the lateral direction will be referred to as the lateral direction.

The inner tube portion (the large diameter inner tube portion 14, the small diameter inner tube portion 15, and the inner tube end portion 16) of the first ferrule 10 is housed in the outer tube housing portion 36 of the second ferrule 30. The upper surface of the inner tube portion end 16 of the first hoop 10 enters below the engaging claw bottom surface 38b of the engaging claw 38 of the second hoop 30. Since the upper surface of the inner tube end portion 16 and the engagement claw bottom surface 38b are both flat surfaces, the first hoop 10 is prevented from falling off.

The elastic edge portion 32 of the second flange 31 has a larger diameter than the first flange 11. A gap is provided between the first flange 11 and the second flange 31.

Referring to fig. 19, the mounting member 51 is sandwiched between the first flange 11 and the second flange 31. The elastic edge portion 32 of the second flange 31 is pressed against the lower surface of the mounting member 51. The large-diameter inner tubular portion 14 of the first ferrule 10 is positioned inside the attachment hole 53 of the attachment member 51.

The inner tube portion of the first ferrule 10 is housed in the outer tube housing portion 36 of the second ferrule 30.

The attached member 61 is provided with a peg 70. The peg 70 passes through the bottom hole 41 of the second ferrule 30, the small-diameter hole 22 of the first ferrule 10, and the large-diameter hole 21 to be exposed above the first flange 11.

The distal end 25a of the locking claw is engaged with the male screw of the pin 70 to prevent the pin locking piece 1 from falling off.

Fig. 20 is an a-a line end view of fig. 18 at a stage before the mounting member 51 is clamped between the first ferrule 10 and the second ferrule 30 and the peg 70 is inserted. Fig. 21 is an end view, a-a, of the stage of fig. 20 to the stage of insertion of the peg 70. In fig. 20 and 21, the mounting member 51, the mounting hole 53, the mounted member 61, and the peg 70 are indicated by two-dot chain lines.

The following operation will be described with reference to fig. 20 and 21: the attachment member 51 is held between the stud retainer 1 composed of the first ferrule 10 and the second ferrule 30, and then the attachment member 51 of the stud retainer 1 is attached to the attached member 61 on which the stud 70 is erected.

Referring to fig. 20, in order to attach the peg lock 1 to the attachment member 51, the second ferrule 30 is disposed below the attachment member 51, and is aligned so that the attachment hole 53 of the attachment member 51 comes above the outer tube housing 36 of the second ferrule 30.

The inner tube portion of the first ferrule 10 is inserted from above the mounting hole 53 of the mounting member 51 and into the outer tube housing 36 of the second ferrule 30.

By this operation, the attachment member 51 is interposed between the first flange 11 of the first ferrule 10 and the second flange 31 of the second ferrule 30. Further, when the first hoop 10 and the second hoop 30 are pushed in so as to press each other, the inner tube portion end 16 of the first hoop 10 pushes and expands the engagement claw tip portion 38a of the second hoop 30 outward to be exposed thereunder. Since the upper surface of the inner tube portion end 16 of the first hoop 10 is engaged with the engagement claw bottom surface 38b of the second hoop 30, the first hoop 10 is prevented from falling off from the second hoop 30.

The mounting member 51 is held between the first flange 11 of the first ferrule 10 and the second flange 31 of the second ferrule 30. In this state, the elastic edge portion 32 of the outer edge portion of the second flange 31 of the second ferrule 30 presses the mounting member 51.

As shown in fig. 20, in a state where the first hoop 10 is prevented from coming off, the engagement claw bottom surfaces 38b of the engagement claws 38 of the second hoop 30 are in contact with the upper surface of the inner tube portion end 16 of the first hoop 10. At this time, a gap h1 exists between the lower surface of the inner tube end 16 of the first ferrule 10 and the receiving portion bottom surface 37 of the second ferrule 30. The gap h1 is a length obtained by subtracting the thickness of the inner tube portion end 16 of the first hoop 10 from the distance from the engaging pawl bottom surface 38b to the receiving portion bottom surface 37.

In this state, when the first ferrule 10 is pressed into the second ferrule 30, the first ferrule 10 and the second ferrule 30 can be brought close to each other until the gap h1 becomes zero. That is, in a state where the first cuff 10 and the second cuff 30 are prevented from coming off, the first cuff 10 can move by the gap h1 in the height direction with respect to the second cuff 30.

When the tip end portion of the peg 70 standing on the attached member 61 is pressed against the guide surface 42a of the second ferrule 30, the tip end portion of the peg 70 is guided toward the bottom hole 41.

As shown in fig. 21, when the first ferrule 10 is further pushed in toward the peg 70, the tip end portion of the peg 70 is guided by the guide surface 42a of the second ferrule 30 and enters the bottom hole 41.

The locking claw 25 formed inside the small-diameter inner cylindrical portion 15 receives the peg 70 by the outward deflection of the peg 70. When pushed further, the catch 25 slides over the thread on the side of the peg 70. The front end of the peg 70 enters the small diameter hole 22 of the first ferrule 10, and the outer peripheral portion thereof is held by 4 protrusions 23 inside the large diameter hole 21 and exposed from the upper surface of the first flange 11.

The engagement claw distal end portion 25a engages with the screw of the peg 70, and the mounting member 51 is mounted to the mounted member 61.

When the distance between the first ferrule 10 and the second ferrule 30 is short and the lower surface of the inner tube end 16 of the first ferrule 10 abuts against the receiving portion bottom surface 37 of the second ferrule 30, the gap h1 becomes 0, and the first ferrule 10 cannot come closer to the second ferrule 30.

At this time, a gap h2 exists between the lower surface of the first flange 11 of the first ferrule 10 and the upper surface of the second flange 31 of the second ferrule 30. The interval h2 is equal to or greater than the plate thickness of the mounting member 51. Therefore, the mounting member 51 is not crushed.

The lower surface of the inner tube portion end 16 of the first band 10 and the receiving portion bottom surface 37 of the second band 30 function as stoppers.

After the mounting member 51 is mounted to the mounted member 61, a straight screwdriver is inserted from the upper surface of the first flange 11 of the first hoop 10 to engage with the protrusion 23, and the first hoop 10 is rotated about the axis of the peg 70, so that the first hoop 10 can be more tightly engaged with the locking claw 25.

When the attached member 61 is, for example, a panel of an automobile, the attaching member 51 to which the stud lock 1 is attached is carried into an assembly line of the automobile or the like.

The assembly worker positions the mounting member 51 to which the stud lock 1 is mounted at a predetermined position on a member 61 to be mounted such as an automobile panel. The mounting member 51 is positioned so that the plurality of pins 70 fixed to the mounted member 61 are respectively fitted into the spaces inside the pin retainers 1.

Since the stud lock 1 is already attached to the mounting member 51, the worker does not need to hold the stud lock 1 by hand, and only needs to perform the operation of aligning the stud lock 1 of the mounting member 51 with the stud 70. When the tip of the peg 70 is brought into contact with the inclined surface portion 42 of the second ferrule 30 and the mounting member 51 is pressed against the mounted member 61, the tip of the peg 70 can be easily guided to the bottom hole 41 of the second ferrule 30 and further guided to the small-diameter hole 22 of the first ferrule 10. Each peg 70 is fixed to the peg catch 1 only by pressing the mounting member 51 against the mounted member 61.

Even if there is a deviation in the position of the peg 70, the leading end of the peg can be guided by the guide surface 42 a. The first flange 11 and the second flange 31 are held at a certain distance, and thus, the mounting member 51 can move in the lateral direction without being more firmly pressed by the first flange 11 and the second flange 31. Each peg 70 is attached to the peg retainer 1.

Conventionally, in a plug fastener provided with two ferrules, a guide for allowing positional deviation of the plug 70 is provided in the inner ferrule. Since the outer diameter of the inner ferrule is small, the range in which the stud can be guided is narrow. In the present embodiment, the guide surface is provided on the second ferrule 30 which is the outer ferrule in order to guide a wide range of pegs.

According to the present embodiment, when the peg 70 is inserted into the small-diameter hole 22 of the first hoop 10 from the bottom hole 41 of the second hoop 30, the receiving portion bottom surface 37 abuts against the lower surface of the inner tube portion end 16, and the first hoop 10 cannot be further pushed in.

A certain gap can be maintained between the first flange 11 of the first ferrule 10 and the second flange 31 of the second ferrule 30, and the mounting member 51 is not excessively compressed. Therefore, the mounting member 51 can move in the lateral direction. The guiding of the peg 70 in the transverse direction is performed well.
