The present invention relates to a slide handler which is mounted on a top end side of a handle lever of which a base end side is attached to a slider of an operated member.
Generally, there has been known a handle tab of an arc-shaped fader as this kind of slide handler (see Patent Document 1). In the arc-shaped fader, a lever shaft is attached to a flange-like movable piece (slider) and the flange-like movable piece is slidably supported in an arc-shaped slits which are formed in a right frame and a left frame, respectively. A handle tab (slide handler) is mounted to fit on a top end portion of the lever shaft.
Since such a known handle tab (slide handler) is attached to fit on the top end portion of the lever shaft (handle lever) by light press fitting or the like, backlash develops between the handle tab and the lever shaft over frequent usage. When attrition therebetween progresses, there arises a problem such that the handle tab can be easily pulled off (can be lost). While, in a case that the handle tab is designed to be pressed strongly to fit on the lever shaft, a problem may be envisioned in which the handle tab can not be readily exchanged when it breaks.
It is an advantage of the invention to provide a slide handler which can be mounted in a securely retained state on a handle lever and can be easily detached therefrom as necessary.
According to one aspect of the invention, there is provided a slide handler mounted on a top end portion of a handle lever of which a base end side is attached to a slider of an operated portion having a handler body that has a lever reception portion in which the handle lever is received, a mount attachment that has a lever locking portion relatively fitted and mounted in the lever reception portion in a state that the lever locking portion is locked on the handle lever and that has a hook portion hooked in the lever reception portion in a state that the fitting and mounting is completed, and a pressing member that is detachably mounted on the handler body and presses the hook portion in the lever reception portion in a hooking direction.
According to the structure, when the mount attachment is relatively fitted and mounted in the lever reception portion of the handler body in a state that the lever locking portion is locked on the handle lever, the hook portion of the mount attachment is hooked in the lever reception portion. This makes the handler body immovably mounted on the handle lever. Further, the pressing member is mounted on the handler body in that state, the hook portion is pressed in the lever reception portion in a hooking direction, thereby the handler body is in a locked state on the handle lever by way of the hook portion. While, the pressing member is detached from the handler body from the locked state, the locked state is released. In short, it is possible to mount the handler body on the handle lever securely in the locked state and is possible to easily detach the handler body as needed. It is preferable that the hook portion is strong against a tension direction and weak against a bending direction. Still further, since a configuration of the handler lever in AV equipment is almost identical, it is generally possible to attach the slide handler of the invention on new and existing handle levers.
In this case, it is preferable that the hook portion exert spring force in a bending direction including the hooking direction, and the lever reception portion have a hook reception portion on which the hook portion is hooked, a guide groove that guides relative hooking action of the hook portion in a free state on the hook reception portion, and a hooking introduction portion that is provided between the hook reception portion and the guide groove and bends the hook portion just before hooking from the free state.
According to the structure, when the mount attachment is relatively fitted and mounted (hooking action) in the lever reception portion of the handler body, the hook portion relatively moves along the guide groove in the free state, thereby the mount attachment does not receive the spring force from the hook portion until just before that the hook portion is hooked. Therefore, as to the fitting and mounting, the mount attachment can not be inclined and the fitting and mounting can be performed smoothly. Since the hook portion is relatively bent by the hooking introduction portion just before being hooked in the hook reception portion, an operator can feel following hooking on the hook reception portion. Therefor it is possible to certainly avoid a mounting defect of the mount attachment to the handler body.
In this case, it is preferable that the lever reception portion have a lever retention portion in which the handle lever is relatively inserted and mounted and the handle lever be inserted in the lever retention portion preceding to the hooking of the hook portion on the hook reception portion.
According to the structure, since the handle lever has been already inserted in the lever retention portion just before that the hook portion is hooked on the hook reception portion, spring force of the hook portion run on the hooking introduction portion is received by the lever retention portion. Therefore, it is possible to fit and mount the mount attachment in the lever reception portion (up to the hooking of the hook portion) smoothly.
Further, it is preferable that the lever reception portion have an attachment fitting portion on which the lever locking portion of the mount attachment is relatively fitted and mounted, and a base end surface of the mount attachment and a base end surface of the handler body be coplanar in a state that the lever locking portion is fitted in the lever reception portion and the hook portion is hooked in the lever reception portion. Still further, it is preferable that, with respect to a slider moving direction, a gap between the lever reception portion in the fitting state and the lever locking portion of the mount attachment in a vertical direction be small. This prevents the mount attachment from turning and can reduce backlash of the handler body.
According to the structure, since the mount attachment is hidden in the handler body mounted on the handle lever and can not be seen from an outside, a design of the handler body can not be degraded by the mount attachment.
Further, it is preferable that the lever locking portion have a pair of clamp spring portions that clamp to lock on the handle lever and a base portion on which the handle lever clamped by the pair of clamp spring portions is struck in a positioning state and from which the hook portion projects.
According to the structure, the handle lever is held at three points by the mount attachment fitted and mounted in the lever reception portion. In other words, the handle lever is held by the pair of clamp spring portions and the base portion of the lever locking portion. Therefore, the handler body can be mounted on the handle lever without backlash.
In this case, it is preferable that the pair of clamp spring portions and the base portion be disposed side by side in a direction orthogonal to a handling direction of the handle lever.
According to the structure, it is possible to dispose the handle lever and the mount attachment in the lever reception portion in a small space and the handler body can have any configuration (does not become large) even if the mount attachment is provided.
Further, it is preferable that the pressing member be mounted on the handler body from an opposite direction to a direction in which the mount attachment is fitted and mounted on the handler body and have a pressing boss formed with a cam inclined surface by which the hook portion is pressed in the hooking direction.
According to the structure, when the pressing member is mounted on the handler body, the cam inclined surface of the pressing boss automatically presses the hook portion in the hooking direction. Therefore, it is possible to easily set the handler body in the locked state. With a reverse procedure, the locked state of the handler body can be easily released.
While, it is preferable that the handler body have a slit groove portion that communicates with the lever reception portion and extends in a direction orthogonal to the handling direction, and the pressing member be formed in a plate-like shape and is detachably mounted in the slit groove portion.
According to the structure, it is possible to detachably mount the pressing member without worsening appearance configuration and strength of the handler body.
In this case, it is preferable that the pressing member be a position indicating member that indicates a handling position of the handler body.
According to the structure, the position indication member of the handler body and the pressing member can be structured by one member, which limits increase of the number of members. Further, in order to indicate the position of the handler body, the handler body does not need to be formed by a two-colored molding process and the handler body and the pressing member can have a simple configuration by molding. Therefore, production cost will be reduced as a whole. It is preferable that the handler body and the pressing member be colored with different colors to get enough contrast therebetween.
Further, it is preferable that an exposed surface of the pressing member mounted in the slit groove portion be formed approximately to be coplanar with an external surface of the handler body.
According to the structure, the pressing member does not project from the handler body seen from an outside, and design and operability of the handler body is not degraded.
Further, it is preferable that the slit groove portion extend to a base end of the handler body.
According to the structure, it is possible to easily detach the pressing member from the handler body by using the extended portion of the slit groove portion. In short, it is possible to detach the pressing member from the handler body without using a jig or the like and to release the locked state of the handler body on the handle lever.
It is preferable that the handler body have an engagement reception portion that engages with the mounted pressing member, and the pressing member have an engagement portion that engages with the engagement reception portion snappingly.
According to the structure, the mounted pressing member does not easily fall off from the handler body and a mounting defect of the pressing member on the handler body can be effectively prevented by the snap.
According to the invention, since the pressing member detachably mounted on the handler body presses the hook portion in the hooking direction with respect to the lever reception portion, the handler body is in the locked state with respect to the handle lever when the pressing member is mounted on the handler body, and the locked state is released when the pressing member is detached from the handler body. Therefore, it is possible to securely mount on the handle lever in the locked state and to detach easily as needed.
A slide handler according to one embodiment of the invention will be explained with reference to accompanying drawings. The slide handler is used for a handle tab, for example, of a fader of AV equipment and is detachably mounted on a handle lever of the fader for manipulating sound volume or sound quality.
As illustrated in an exploded perspective view of
The handle lever 5 is made of an aluminum or a stainless steel plate which is processed by a press punching process, and a pair of hook grooves 11, 11 are formed at an intermediate position in an extending direction (vertical direction in
The mount attachment 3 is a plastic molding and is integrally formed by a lever locking portion 21 which is relatively fitted and mounted in the above mentioned lever reception portion 7 in a state that it is locked on the handle lever 3, and a hook portion 22 which is hooked in the lever reception portion 7 in a state that the fitting and mounting is completed. The lever locking portion 21 has a pair of clamp spring portions 23, 23 which lock to clamp on the handle lever 5, and a base portion 24 on which the handle lever 5 clamped by the pair of clamp spring portions 23, 23 is struck in a positioning state and from which the hook portion 22 projects. The pair of clamp spring portions 23, 23 are mounted with the handle lever 5 on an intermediate position of the handler body 2 in a width direction (horizontal direction), and the hook portion 22 and the base portion 24 are mounted at a position offset to either side from the intermediate position of the handler body 2 in the width direction (horizontal direction). After the mounting completes, a bottom surface (base end surface) of the base portion 24 and a bottom surface (base end surface) of the handler body 2 are coplanar.
Upper half portions of the pair of clamp spring portions 23, 23 incline inwardly in accordance with a configuration of the lever reception portion 7 and allow the handle lever 5 to have strong clamp force after fitting and mounting in the lever reception portion 7 (see
The hook portion 22 is integrally formed by a plate spring portion 27 which is formed at a center portion of the base portion 24 in the vertical direction and a hook piece 28 which is provided at a top end portion of the plate spring portion 27. The plate spring portion 27 is formed in a thin plate shape and exerts relatively weak spring force in a bending direction. A lower surface of the hook piece 28 is orthogonal to the plate spring portion 27 and an upper surface thereof is inclined so as to form a triangle seen from a lateral side, and the hook piece 28 is hooked on a hook reception portion 42 described later of the lever reception portion 7 when the mount attachment 3 completes to fit and engage with the lever reception portion 7 (see
The indication line member 4 has functions by which the handler body 2 is kept in a locked state to the handle lever 5 by pressing the hook portion 22 in a locking direction against the lever reception portion (the hook reception portion 42 described later) 7, and by which an operation position of the handler body 2 is indicated when it is mounted on the intermediate position of the handler body 2 in the width direction (operation direction).
The indication line member 4 which constitutes a separate member from the handler body 2 is a plate-shaped plastic molding, and is integrally formed by an upside-down “U-shaped” member body 31 which constitutes a main body, a pressing boss 32 extending downwardly from an inside of the member body 31 and pressing the above mentioned hook portion 22, and an engagement portion 33 extending downwardly together with the pressing boss 32 from the inside of the member body 31.
In a state that the indication line member 4 is mounted in the above mentioned slit groove portion 8, a peripheral surface of the member body 31 is exposed at the intermediate position of the handler body 2 in a thickness direction and the member body 31 indicates an operation position of the handler body 2. In short, when the indication line member 4 is mounted in the slit groove portion 8, the member body 31 is set to a position at which the peripheral surface thereof is coplanar with or slightly under the upper surface and both side surfaces of the handler body 2 (see
The pressing boss 32 projects in a shape of square from the member body and a side which is engaged with the hook member 22 forms a cam inclined plane 32a. When the indication line member 4 is mounted in the slit groove portion 8, the cam inclined plane 32a of the pressing boss 32 presses the hook piece 28 of the hook portion 22 which is hooked in the lever reception portion (hook reception portion 42) 7 from a rear side (see
The engagement portion 33 projects lengthwise in a shape of rectangle from the member body 31 and a rectangular engagement aperture 35 is formed in a lower half portion thereof. In a state that the indication line member 4 is mounted in the slit groove portion 8, the engagement portion 33 exerts spring force in an orthogonal direction to an in-plane direction and engages in a boss-shaped engagement reception portion 52 described later snappingly. In other words, when the indication line member 4 is gradually mounted in the slit groove portion 8, a top end of the engagement portion 33 runs on the engagement reception portion 52 and the engagement reception portion 52 fits in the engagement aperture 35 snappingly, thereby the indication line member 4 is mounted in the handler body 2 completely (see
As illustrated in
In other words, the handler body 2 has a structure in which a pair of body element members 2A, 2A facing in the operation direction where the indication line member 4 is provided therebetween are connected by the portion on which the above described hook portion 22 is hooked, the portion in which the handle lever 5 is inserted, and a portion which guides to mount the indication line member 4. In short, the lever reception portion 7 and the slit groove portion 8 are formed in a space (space opening downwardly) between the pair of body element members 2A, 2A except the above described connection portions. Each connection portion does not come up with undercut in molding and has a shape which can be molded only with top and bottom molds.
The portion on which the hook portion 22 is hooked is formed by a partition portion 41 which extends upwardly from the lower ends of the pair of body element members 2A, 2A and the hook reception portion 42 where the hook piece 28 of the hook portion 22 is hooked on is formed on an upper end of the partition portion 41. At a side facing to the hook portion 22 of the partition portion 41, a guide groove 43 which guides the hook portion 22 in a free state to relatively hook on the hook reception portion 42 and a hooking introduction portion 44 which bends the hook portion 22 in the free state just before hooking are formed (see
A transit portion from the upper end of the guide groove 43 to the hooking introduction portion 44 is an inclined surface for bending the hook portion 22 in the free state. The hook piece 28 in the free state of the hook portion 22 relatively inserted into the lever reception portion 7 is guided by the guide groove 43. After the hook piece 28 runs on the hooking introduction portion 44, the hook portion 22 bends backwards, and finally the hook piece 28 moves from the upper end of the hooking introduction portion 44 to the hook reception portion 42, leading to hook the hook portion 22 on the hook reception portion (partition portion 41) 42 (see
The portion into which the handle lever 5 is inserted is formed by a pair of facing plate portions 46, disposed between upper portions of the pair of body element members 2A, 2A (see
A position of the top end of the handle lever 5 relatively inserted between lever retention portions 47 is set such that the hook portion 22 of the mount attachment 3 runs on the hooking introduction portion 44 at a position just before the completion of the insertion, and the top end portion of the handle lever 5 begins to insert (is inserted precedingly) between the lever retention portions 47 before the hook portion 22 in the free state reaches to the hooking introduction portion 44 (see
The pair of clamp spring portions 23, 23 of the mount attachment 3 locked on the handle lever 5 are positioned in right and left directions by two positioning bosses at a left side and two positioning bosses at a right side, that is, four positioning bosses in total each of which projects from the pair of body element members 2A, 2A at a lower side of the pair of facing plate portions 46, 46 (see
The upper half portions of the pair of clamp spring portions 23, 23 which are fitted and mounted and the pair of body element members 2A, 2A are formed in a complementary shape (comparatively tight fitting), and the pair of clamp spring portions 23, 23 clamp the handle lever 5 strongly in a state that the mount attachment 3 is mounted completely in the attachment fitting portion (lever reception portion 7) 49 (see
The portion which guides to mount the indication line member 4 is a portion corresponding to a spaced portion between one leg portion 31a of the member body 31 and the engagement portion 33 of the indication line member 4 and is formed by a connection portion 51 provided between the pair of body element member 2A, 2A (see
Further, at an inner side of one of the body element members 2A, 2A, the engagement reception portion 52 which is engaged with the engagement portion 33 of the indication member 4 snappingly is formed adjacent to the connection portion 51. The engagement reception portion 52 is a planar projection piece which projects inside the body element member 2A and a projection piece 52a of which upper and lower portions are inclined to form a trapezoidal shape is formed on the top end portion thereof (see
Referring to
Then, as illustrated in
Then, the indication line member 4 is mounted in the handler body 2 mounted on the handle lever 5 from an upper side. First of all, the indication line member 4 is positioned to an outer shape of the handler body 2 and is inserted therein. As the insertion progresses, the pressing boss 32 of the indication line member 4 gets into touch with the hook portion 22 and begins to press the hook portion 22, and the engagement portion 33 runs on the engagement reception portion 52 (see
While, in a case that the handler body 2 breaks or gets dirty, or the slider needs maintenance or replacement, the handler body 2 is detached by a reverse procedure described above. Specifically, the operator inserts a nail under a lower end of the slit groove portion 8 and pushes out the indication line member 4. This allows the engagement portion 33 to come off from the engagement reception portion 52. Then, the user olds and pulls out the upper end portion of the indication line member 4 which is out of the handler body 2. Finally, the operator pulls out the handler body 2 strongly to disengage the hook portion 22 with the hook reception portion 42.
As stated above, according to the embodiment, since the handler body 2 is mounted on the handle lever 5 attached with the mount attachment 3 having the hook portion 22 and the indication line member 4 is mounted on the handler body 2 to press the hook portion 22 in the hooking direction, the handler body 2 can be mounted immovably and in the retained state on the handle lever 5. Further, the handler body 2 can be easily dismounted from the handle lever 5 by detaching the indication line member 4 from the handler body 2. Further, it can be easily manufactured at low cost by the indication line member 4 having two functions. Still further, the slide handler 1 can have general versatility.
The pressing member which presses the hook portion in the hooking direction is not necessarily the indication line member which indicates an operation position of the handler body, and is not limited thereto only if the pressing member is mounted on the handler body and presses the hook portion in the hooking direction. Further, the hook piece of the hook portion may be bent inwardly and may hook on the pair of facing plate portions above. Still further, a boss may be provided on the engagement portion, an aperture may be formed in the engagement reception portion and the boss may engage in the aperture snappingly.
