  The mode for carrying out the present invention includes an embodiment described below as well as various improved embodiments based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
What is indicated by the symbol R is a latch device according to the present invention, which includes various exterior parts of the motorcycle M as application parts m as shown in FIGS. Used. For example, as an example of the application part m, it is one suitable example to be applied to a support member at the rear portion of the seat called a sea sieve m1, and a case where it is applied to the sea sieve m1 will be described below.
First, in the motorcycle M, the seesieber m1 is mounted mainly on the so-called cruiser type, chopper type, American type, etc., and the seesieber m1 itself has the owner's preference as a mounting part. It is a part that is reflected. Therefore, it is welcomed by the owner that they can be attached and detached freely.

Hereinafter, the latch device R will be described in detail.
The latch device R uses the seesieber m1 as an example of the application component m. The latch body 2 is movably attached to the bracket member 1 which is a part of the sea sieve m1 as one component member. Further, an urging spring 3 for urging the latch body 2 with respect to the bracket member 1 in a fixed direction and a presser plate 4 for maintaining the assembled state are provided.
And such a latch device R is attached, and the seesieber m1 is attached to the frame 5 of the motorcycle M. Of course, the frame 5 includes a frame as a main member of the vehicle body and a sub-frame that is appropriately extended from the frame.

The bracket member 1 is formed on a part of the lower plate 10 of the seesieber m1. The lower plate 10 is formed in a substantially inverted T shape when viewed from the side. A locking notch 11 is provided at the front end of the lower plate 10, and the locking plate formed on the frame 5 on the motorcycle M side. It takes a form that can be inserted into the striker 50. The lower plate 10 forms a bar support plate 12 so as to rise from the center thereof, and a rectangular tubular bar insertion tube 13 is provided on the inner side thereof, and the lower end of the arch-shaped sea-sieber main body 14 is provided here. It is inserted.
As an example, the lower plate 10 having such a bracket member 1 is formed with a striker receiving portion 15 in a notch shape at the lower rear end, the lower portion being opened. The definition of up / down or front / rear is defined as front / rear with the front in the traveling direction of the motorcycle M to which the seesiever m1 is applied as front, and the up / down direction of the vehicle body is defined as up / down. Of course, in the latch device R, depending on the form of the application part m, such a front / rear and upper / lower definition may not be appropriate. Therefore, the front / rear and upper / lower definitions are not absolute. Other appropriate expressions are also adopted with the primary goal of accurately grasping the technical contents.

The striker receiving portion 15 receives the lock striker 51 protruding from the frame 5 and holds the lock striker 51 by the latch body 2 so that the bracket member, that is, the overall sea-sieber m1 is attached to the vehicle body.
A pivot pin 16 is fixedly attached to the bracket member 1 on the upper side from the striker receiving portion 15. In addition, the selector pin 17 is similarly attached to the bracket member 1 at a position which is further forward and slightly deviated downward. The pivot pin 16 and the selector pin 17 are preferably provided with a freely rotatable sleeve so that the operation can be facilitated. In this embodiment, the pivot pin 16 has a sleeve 16a.
The pivot pin 16 is a component of the bracket-side slide / pivot guide mechanism G1 in the slide / pivot guide mechanism G defined in the claims, while the selector pin 17 is also a bracket-side selector of the selector guide mechanism S. It is a structural member of the guide mechanism S1.
As a result of such an arrangement, as an example, the pivot pin 16, the selector pin 17, and the striker receiving portion 15 are triangularly arranged in a side view.

Next, the latch main body 2 assembled to the bracket member 1 will be described.
The latch body 2 is a substantially flat member that is partially hooked and shaped to hold the lock striker 51. In general, in this embodiment, a shift action portion 20 is formed on the upper side, and a hook portion 21 extending downward therefrom is integrally formed.
First, a pivot hole 22 is formed in the shift action portion 20 at a position deviated rearward from the center. The pivot hole 22 is in the shape of a long hole, and the long axis of the long hole shape is formed in a so-called front-down shape that is somewhat lowered toward the front. In other words, the extension line of the long axis of the pivot hole 22 takes an arrangement shape that crosses the line connecting the center of the selector pin 17 and the center of the striker receiving portion 15 therebetween.
Further, the pivot hole 22 is formed by integrally extending a spring accommodating portion 23 formed in a narrow width from the front end portion. As a result, the overall side view shape of the spring accommodating portion 23 and the pivot hole 22 is a shape expressed as a wing plate shape or a racket shape.

Further, an opening guide cam groove 24 and a restraining guide cam groove 25 are continuously formed on the front end side of the shift action portion 20, and an intermediate position thereof is a partition convex portion 26. These open guide cam grooves 24 are relatively shallow cam grooves, while the restraining guide cam grooves 25 are deep grooves.
The pivot hole 22 is a component of the latch-side slide / pivot guide mechanism G2 in the slide / pivot guide mechanism G defined in the claims, and includes one open guide cam groove 24 and a restraint guide cam groove. Reference numeral 25 denotes a constituent member of the latch-side selector guide mechanism S2 of the selector guide mechanism S.
Furthermore, the hook part 21 in the latch body 2 will be described. The hook portion 21 has a shape expressed as a bowl shape, and a space formed inside the hook portion 21 serves as a striker restraining portion 27. The striker restraining portion 27 has a restraining opening 27a on its front side and an inner edge on the protruding tip side as a striker pressing edge 27b. A portion that is continuous from the edge of the striker restraining portion 27 and forms the lower edge of the shift action portion 20 is defined as a striker contact edge 28.

  A biasing spring 3 that contributes to the assembly of the bracket member 1 and the latch body 2 is provided in a contracted state in the spring receiving portion 23 of the latch body 2, and a guide piece 30 is appropriately applied thereto. , To ensure its stable assembly. Note that the urging spring 3 is considered to be a part of the constituent members of the slide / pivot guide mechanism G and the selector guide mechanism S in consideration of the function.

  Furthermore, in order to obtain the assembled state of these members, the presser plate 4 is applied. The presser plate 4 is applied with the presser plate 4 having a shape expressed as an oval shape in a side view with a slightly different front-rear width as an example, and includes a bolt hole 40 and a bolt washer for assembling them. 41 is provided. The assembly state of these members will be further described. First, the pivot hole 22 in the latch main body 2 is attached to the pivot pin 16 in the bracket member 1 so as to fit outside, and the spring accommodating portion 23 is used between them. The urging spring 3 is attached in a contracted state. In this attachment, the guide piece 30 contributes to stable attachment. As a result, the latch body 2 is urged substantially forward with respect to the bracket member 1. That is, one end of the biasing spring 3 abuts on a side end surface of the pivot pin 16 attached to the bracket member 1, and the other end presses the dead end of the spring accommodating portion 23, and as a result, the latch body 2. Always develops a tendency to bias toward the front and slightly downward.

At this time, it is preferable that either the release guide cam groove 24 or the restraining guide cam groove 25 in the latch body 2 is fitted to the selector pin 17, but in consideration of the assembling work, the biasing spring 3 is extended. It is easy to select the fitting with the restraining guide cam groove 25 as shown in FIG. However, such a work is a work at the time of production, and it is extremely rare for a user to actually perform this operation.
After assembling in such a state, the presser plate 4 secures the assembly of the two, and the bolt washer 41 is attached to the female screw hole provided on the bracket member 1 side using the bolt hole 40. It is. In this embodiment, as an example of the most rational arrangement, the female screw 16b and the female screw 17b are formed and attached using the central axes of the pivot pin 16 and the selector pin 17.

Although such a specific configuration and combination form have been described, the latch device according to the present invention to be described below is adopted by adopting a mechanism that allows the latch body 2 to slide somewhat while rotating relative to the bracket member 1. The action of R can be achieved.
However, the present invention is not limited to the optimum embodiment described above, and various variations can be considered. Therefore, the pivot pin 16 on the bracket member 1 side and the long hole shape on the latch body 2 side in the embodiment already described. A mechanism comprising a combination with the pivot hole 22 is defined as a slide / pivot guide mechanism G in the scope of claims. That is, the pivot pin 16 on the bracket member 1 side is defined as the bracket side slide / pivot guide mechanism G1, and the corresponding pivot hole 22 in the latch body 2 is defined as the latch side slide / pivot guide mechanism G2. It is.

The selector pin 17 in the bracket member 1 and the release guide cam groove 24 and the restraining guide cam groove 25 in the latch main body 2 engaged with the selector pin 17 are combined with each other as a selector guide mechanism S. The pin 17 is defined as the bracket-side selector guide mechanism S1, and the release guide cam groove 24 and the restraining guide cam groove 25 provided in the latch body 2 are defined as the latch-side selector guide mechanism S2.
By the way, the definition of such terms is that in the slide / pivot guide mechanism G that allows sliding and allows rotation, the formation relationship between each pin-like member and the long hole-like member is reversed. Further, in the selector guide mechanism S, the formation relationship between the fixed selector pin 17 and the cam groove can be reversed.
Specifically, for example, a pin fixed to the latch body 2 may be protruded, and a slot-like slit that guides the pin may be formed on the bracket member 1 side. In the selector guide mechanism S, It is also possible to have a cam groove on the bracket member 1 side and a protrusion or pin-like member that fits on the latch side selector guide mechanism S2 side, and considering these, the slide / pivot guide mechanism G and The selector guide mechanism S is defined. The specific shape will be described later.

The operating state of the latch device R having such a basic form as applied to the seesieber m1 and the lower plate 10 as an example of the bracket member 1 will be described.
<First departure state>
An operation state when the seesieber m1 is attached to the motorcycle M will be described.
First, the initial posture of the latch body 2 combined with the bracket member 1 is as follows.
As shown in FIG. 4A, the latch main body 2 takes a posture as a whole, that is, the front, that is, the side where the selector guide mechanism S is provided is lowered downward. At this time, the opening guide cam groove 24 in the latch main body 2 is in a position in which the opening guide cam groove 24 is positioned in contact with the selector pin 17 in the bracket member 1. On the other hand, when the positional relationship between the pivot hole 22 formed in the shift action portion 20 of the latch body 2 and the pivot pin 16 in the bracket member 1 is seen, the latch body 2 is formed in the open guide cam groove 24 which is a shallow cam groove. Due to the restriction, the pivot pin 16 is relatively positioned closer to the striker spring receiving portion 23 side in the latch body 2. Therefore, at this time, the urging spring 3 is sufficiently contracted, and the reaction force is received by the selector pin 17 in the bracket member 1 constituting the selector guide mechanism S.

  On the other hand, when the state of the hook portion 21 in the latch body 2 is viewed at this time, the striker restraining portion 27 substantially formed by the hook portion 21 is shown in the upper left in FIG. 4 (1) from the striker receiving portion 15 in the bracket member 1. It is in a state that has been sufficiently moved away. That is, the restraining opening 27a of the striker restraining portion 27 is sufficiently retracted from the striker receiving portion 15. On the other hand, when the striker contact edge 28 connected to the striker restraining portion 27 is viewed, it is lowered downward and projects downward from the upper end of the striker receiving portion 15 in the bracket member 1.

<Lock operation>
In order to attach the seesieber m1 in which the latch device R is in the starting state to the motorcycle M in this way, the locking notch 11 in the lower plate 10 of the bracket member 1 is attached to the front-side locking striker 50 of the frame 5 of the motorcycle M. Inserted from the rear, the seesieber m1 is pressed downward with the locking striker 50 as the center of rotation. When such an operation is performed, the lock striker 51 in the frame 5 first enters the striker receiving portion 15 relatively. Actually, the lock striker 51 is fixed to the frame 5, and the latch device R is lowered from above.

In such a state, as shown in FIGS. 4 (2) to 4 (4), the upper part of the lock striker 51 abuts against the striker contact edge 28 in the latch body 2, and the latch body 2 is moved to this portion. It works to push up. Looking at the latch body 2 at this time, the positioning with respect to the bracket member 1 is performed by the pivot pin 16 and the selector pin 17. The latch body 2 moves in a counterclockwise direction in the drawing. At this time, when viewed from the selector guide mechanism S side, the rotation operation in the latch body 2 starts from the contact state between the open guide cam groove 24 and the selector pin 17 as shown in FIGS. 26, the latch body 2 is further rotated counterclockwise in the drawing, and the restraining guide cam groove 25 having a deep cam groove is fitted into the selector pin 17. Due to the depth of the cam groove and the shape of the elongated hole-shaped pivot hole 22, the latch body 2 is slid toward the selector guide mechanism S as a whole with respect to the bracket member 1. That is, in the slide / pivot guide mechanism G, the latch body 2 is allowed to rotate and the slide is allowed simultaneously. The operation of the urging spring 3 that urges the latch body 2 toward the selector guide mechanism S between the bracket member 1 and the latch body 2 always contributes to such an operation. In this state, when the movement of the hook portion 21 of the latch body 2 is viewed, the hook portion 21 selects a position where the striker restraining portion 27 relatively moves forward, and as shown in FIG. The opening 15a of the striker receiving portion 15 is closed.
<Lock completed, self-locked>
As a result, escape of the lock striker 51 that takes a positional relationship as if entering the striker receiving portion 15 is prevented by the striker presser edge 27 b that is the lower outer edge of the striker restraining portion 27.
In such a state, according to the present invention, as defined in claim 5, the extension line of the elongated hole-like pivot hole 22 is the striker receiving portion 15, the selector, and the selector, regardless of whether the long axis direction is the starting posture or the restraining posture. The position is set so as to cross between the lines connecting the pins 17. With this configuration, the latch device R exhibits a so-called self-locking state even when a force in a direction to release the restraint is applied.
That is, when a force in the releasing direction is applied to the latch device R as shown in FIG. 5, that is, a force F as shown in the figure, the reaction force of the force F extends to F2 which is the normal direction of F1 and tangent. Represented as a vector. When the vector of F2 in the result pivot pin 16 is decomposed in the vertical and horizontal directions, it is expressed as a component force of F2y and F2x. As a result, a component force of F2x that pulls the latch body 2 toward the selector guide mechanism S is generated. Yes. Therefore, this component force acts as an acting component force that moves the latch body 2 in the restraining direction even if a force in the releasing direction is applied to the latch body 2. As a result, the biasing spring 3 can be applied to a member having a weak elasticity such as a positioning action of the latch body 2 and can be further restrained even when an unfavorable force acts in the releasing direction of the latch device R. Acting in the direction of increasing the force, the restraining force as the latch device R is maintained.

<Release action>
When the latch device R locked in such a state is released, it is manually operated. As shown in FIGS. 6 (1) to 6 (4), the operation handle 20A and the operation handle 21A are formed in a slightly uneven state on the shift action portion 20 and the hook portion 21 in the latch body 2. Each operator puts his finger and performs an operation of turning the front in the clockwise direction in the drawing while pulling back this. Thereby, the fitting between the restraining guide cam groove 25 and the selector pin 17 moves to the open guide cam groove 24 side beyond the partition convex portion 26, and the relationship between the pivot pin 16 and the pivot hole 22 is relatively A form in which the pivot pin 16 moves toward the front end of the pivot hole 22 is adopted, and a release state is caused to appear.

[Other embodiments]
The present invention is based on the embodiment described above as one basic technical idea, but the following modifications can be considered.
<Other embodiments of the urging spring>
The urging spring 3 only needs to be able to always bias the latch body 2 toward the selector guide mechanism S. For example, a torsion coil spring is applied as shown in FIG. 16, the left and right working ends may be engaged with the latch body 2, and the latch body 2 may be biased in the direction indicated by the arrow A. Of course, in addition to such a spring, a tension type coil spring as shown in FIG. 7B may be applied as the biasing spring 3 to bias the latch body 2.
Furthermore, in the embodiment already described, a spring that can be pressed by a rubber block instead of a metal spring can be applied as the urging spring 3 if possible.

<Another embodiment of the slide / pivot guide mechanism G>
First, with respect to the slide / pivot guide mechanism G, in the embodiment already described, the bracket-side slide / pivot guide mechanism G1 uses the pivot pin 16, while the latch body 2 side has a long-hole-like pivot hole 22. However, this relationship can be reversed. That is, as shown in FIGS. 8 (a) and 8 (b), a pivot pin 216 is formed on the latch body 2 side, while the bracket member 1 side is provided with a long hole-like pivot hole 122 into which the pin is fitted. It is. Of course, in this case, as shown in the figure, for the long hole-shaped pivot hole, in addition to the pivot hole 122 being arranged in parallel on the bracket member 1 side, the long hole-shaped pivot hole 422 is also formed on the presser plate 4. You can leave it.

<Another embodiment of the selector guide mechanism S>
The selector pin 17 provided on the bracket member 1 constituting the selector guide mechanism S, the open guide cam groove 24 provided on the latch body 2 side, and the restraining guide cam groove 25 can be reversed. That is, as shown in FIG. 8, a projection member 217 is formed on the selector guide mechanism S side of the latch body 2 instead of the cam groove, whereas an open guide cam groove 124 and a restraining guide cam are formed on the bracket member 1 side. A groove 125 is formed. In this case, since the vertical arrangement is reversed, the open guide cam groove 124 is disposed below, that is, on the striker receiving portion 15 side of the bracket member 1, and the deeper constraining guide cam groove 125 is disposed above it. It will be installed continuously. Reference numeral 126 denotes a partition convex portion.

<Other Embodiments of Applicable Parts m>
The embodiment described above is a form of various embodiments of the latch device R. Next, the applicable component m in the motorcycle M will be described. In the above description, the exterior component as the application component m to which such a latch device R is preferably applied is the sea-sieber m1 as an example, but various developments are possible. The mechanism itself of the latch device R applies the one already described, and although the illustration is simplified, the rear carrier m2, the carry box bracket m3, the front windshield m4, the seat m5, the fuel tank m6, the oil The tank m7, the rear fender m8, the front number plate m9, the side panel m10, the carry box m11, and the like can be applied. As for the rear fender m8, as shown in FIG. 9, in the case of the motorcycle M having a strong competition orientation, the rear fender m8 provided with safety parts and a license plate is attached to the public road to be removed with one touch during the competition. There is a request, and this latch device R is effective. Similarly, application to a front number plate m9 incorporating a headlight or the like, or a side panel m10 serving as a side number plate is effective.
