Japanese Unexamined Patent Application Publication No. 2012-273

However, conventional transmitters for radio-controlled models are configured so that the entire grip unit can be replaced according to the user's preference, so as to meet the needs of the size, thickness, and material of the grip part. It is Therefore, the grip unit used as a replacement part tends to be large and heavy. In order to fix large and heavy replacement parts with high rigidity and detachably, there is concern that the fixing structure will be complicated and large, and the weight of the entire transmitter will increase.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a radio control transmitter and a grip for the radio control transmitter that can realize a grip portion with a small grip diameter while suppressing an increase in the weight of the entire transmitter. to provide cover.

Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The radio control transmitter 1 according to claim 1 of the present invention includes a columnar grip portion 3,
a head portion 5 provided at one end of the grip portion 3 and having a steering antenna 12;
A radio control transmitter comprising a base portion 4 formed with a larger diameter than the grip portion 3 and provided at the other end of the grip portion 3,
The grip portion 3 has a grip main body portion 13 in which a ridge portion 18 is formed along the longitudinal direction between the fingers of the thumb and forefinger. The grip cover 8 has an elongated hole 22 for exposing the penetrating tip surface of the grip 18 and is fitted with a grip cover 8 that covers the half 15 of the grip main body 13 facing the palm.

In this radio control transmitter 1, a grip portion 3 has a grip body portion 13 having a head portion 5 at one end and a base portion 4 at the other end. The grip body portion 13 connects the head portion 5 and the base portion 4 and has rigidity as a structure capable of supporting them together. The grip main body portion 13 is formed with a ridge portion 18 along the longitudinal direction on the inter-finger side between the thumb and the forefinger. The half of the grip main body 13 on the side where the ridges 18 are provided serves as the rear half 15 with which the inter-finger portion is in contact.
A grip cover 8 having an elongated hole 22 through which the ridge 18 passes is attached to the rear half 15 of the grip main body 13 . The grip part 3 is gripped by the user with the grip cover 8 attached. The grip cover 8 has an elongated hole 22 through which the protrusion 18 penetrates so that the material of the portion corresponding to the protrusion 18 is reduced. That is, the weight is reduced by that amount.
Since the radio control transmitter is detachably attached to the grip main body 13 with the grip cover 8 made lighter by the long hole 22, the entire grip unit can be adjusted according to the size and thickness of the grip as in the conventional case. This eliminates the need for a detachable fixing structure that is highly rigid and heavy compared to replacing the entire unit. That is, the lightweight and compact grip cover 8 can be detachably attached with a simple locking claw structure.
In addition, since the inter-finger portion of the grip cover 8 is in contact with the penetrating tip surface of the protrusion 18 penetrating the elongated hole 22 of the grip cover 8, the direction is the same as when the grip cover 8 is not attached. becomes. Most importantly, the distance between the index finger and the trigger 2 can be minimized. This makes the grip portion 3 optimal for users with small hands, such as children with small grip diameters.

The radio control transmitter according to claim 2 of the present invention is the radio control transmitter according to claim 1,
The penetrating tip surface of the ridge portion 18 is characterized in that a textured surface is formed.

In this radio control transmitter, when the grip cover 8 is attached to the grip main body 13, the embossed surface of the penetrating tip surface of the projection 18 penetrating the elongated hole 22 of the grip cover 8 is exposed. The material of the grip cover 8 is, for example, an elastomer. The surface of the grip cover 8 is non-slip. As a result, when the grip cover 8 is attached to the grip main body 13, the grip cover 8 has a rubber-like texture, so that it can be comfortably gripped (grasped) and a good steering feeling can be obtained. When the grip cover 8 is attached to the grip part 3 , the grip cover 8 is positioned on both the left and right sides of the protrusion 18 . It is possible to obtain two anti-slip actions on the surface of the grip part 3, namely, anti-slip action by the embossed surface of the part 18. - 特許庁

The radio control transmitter according to claim 3 of the present invention is the radio control transmitter according to claim 1 or 2,
A groove portion 29 is formed at the boundary between the long hole 22 and the penetrating tip surface.

In this radio control transmitter, a groove portion 29 is formed at the border between the penetrating tip surface of the projection portion 18 of the grip body portion 13 and the long hole 22 of the grip cover 8 . With the presence of this groove portion 29, when the user grips the grip portion 3, a gap is created between the user's hand and the grip 3, and ventilation can be ensured.

The radio control transmitter according to claim 4 of the present invention is the radio control transmitter according to claim 1 or 2,
The grip portion 3 is characterized in that other grip covers 24 and 27 that cover the ridge portion 18 without the long hole 22 are detachably attached.

In this radio control transmitter, a grip cover 8 and other grip covers 24 and 27 are detachably and selectively attached to the grip body portion 13 . As described above, the grip cover 8 has a finger-to-toe portion in contact with the penetrating tip surface of the protrusion 18 penetrating the elongated hole 22 of the grip cover 8, so that the grip cover 8 may not be attached in that direction. It is the same and can be optimized for users with smaller hands, such as children with smaller grip diameters. On the other hand, the other grip cover 8 does not have the elongated hole 22, and the distance in the direction in which the finger-to-toe portion contacts is increased by the thickness of the portion covering the protrusion 18, so that the diameter of the constricted portion 17 can be increased. Thereby, the user can select either the grip cover 8 or the other grip covers 24 and 27 to change the grip diameter and adjust the optimal grip condition according to the user's preference.

A grip cover for a radio control transmitter according to claim 5 of the present invention is a grip cover for a radio control transmitter attached to a grip portion 3 of a radio control transmitter,
It is detachably attached to the grip main body portion 13 of the grip portion 3 in which a ridge portion 18 is formed along the longitudinal direction on the inter-finger side between the thumb and index finger, and the ridge portion 18 is penetrated to extend the protrusion. It is characterized by having an elongated hole 22 for exposing the penetrating tip surface of the streak 18 and covering the half of the grip main body 13 facing the palm.

This grip cover for a radio control transmitter is provided with an elongated hole 22 through which a ridge portion 18 provided on the grip body portion 13 penetrates. The radio control transmitter grip cover (grip cover 8 ) is attached so as to cover the grip main body 13 by penetrating the elongated hole 22 through the protrusion 18 . The material of the grip cover 8 corresponding to the protrusion 18 is reduced, and the weight is reduced accordingly.
Since the finger-to-toe portion of the grip cover 8 touches the penetrating tip surface of the protrusion 18 penetrating the long hole 22 of the grip cover 8, the direction is the same as when the grip cover 8 is not attached. That is, the distance between the index finger and the trigger 2 can be minimized. Accordingly, by attaching the grip cover 8 to the grip portion 3, the grip portion 3 can be optimized for users with small hands, such as children with a small grip diameter.

According to the radio control transmitter of claim 1 of the present invention, a grip portion with a small grip diameter can be realized while suppressing an increase in the weight of the entire transmitter. This makes the grip optimal for users with smaller hands, for example children with smaller grip diameters.

According to the radio control transmitter of claim 2 of the present invention, the embossed surface of the ridge exposed from the long hole of the grip cover prevents slippage, so that even a user with small hands can firmly grip the transmitter.

According to the radio control transmitter of claim 3 of the present invention, the groove formed at the boundary between the penetrating tip surface of the ridge of the grip body and the elongated hole of the grip cover allows the user to hold the grip. When gripped, a gap is created between the user's hand and the grip, and ventilation can be ensured.

According to the radio control transmitter according to claim 4 of the present invention, while suppressing an increase in the weight of the entire transmitter, it is possible to change the color, change the design (pattern), feel and grip (softer or harder). etc.) can be accommodated.

According to the grip cover for a radio control transmitter according to claim 5 of the present invention, it is possible to cope with a small-diameter grip portion while suppressing an increase in the weight of the entire transmitter.

In this example, an example in which the controlled object remotely controlled by the transmitter 1 is a model automobile will be described. Further, the description will be made on the assumption that an engine is used as the power source for the controlled object, but a motor can also be used as the power source.

FIG. 1 is a perspective view of a radio control transmitter according to the present invention as seen obliquely from the lower rear.
As shown in FIG. 1, the transmitter 1 generally comprises a grip portion 3, a base portion 4, and a head portion 5. The casing of each portion is made of flexible thermoplastic resin (for example, general-purpose plastic). It is

One end (upper side) of the grip part 3 is integrated with the head part 5, and the other end (lower side) is integrated with the base part 4. formed in The grip part 3 functions as a grasping part that is grasped by the operator when remotely controlling the object to be controlled.

The base portion 4 is provided at the other end (lower side) of the grip portion 3 and is formed in a rectangular shape. The base portion 4 regulates the lower limit position of the hand that grips the grip portion 3 to prevent the hand from slipping out of the grip portion 3, and also prevents the transmitter 1 from being put upright on the ground, for example, when not in use. It also functions as a leg having a predetermined installation area on the bottom surface.

Also, the base portion 4 is provided with a switch mechanism 7 for operation when the operator is operating the wheel 6 and the trigger 2 with both hands. FIG. 1 shows an example in which the switch mechanism 7 is provided at the end on the operator side when the operator grips the grip part 3 . The switch mechanism 7 is designed so that the operator operating with both hands touches a part of the body other than the fingers of both hands (for example, chest, abdomen, shoulders, crotch, knees, etc.) or nearby objects (for example, handrails in a stadium). By pulling the transmitter 1 to switch it on and off, the function assigned to the switch mechanism 7 can be activated.

The functions assigned to the switch mechanism 7 include, for example, turning on/off the turbo function, mixing, gyro operation, lap measurement, sudden braking, camera, and the like. By assigning the function, the switch mechanism 7 can be operated instantaneously by making a quick decision in case of an emergency, and the function assigned to the switch mechanism 7 can be immediately turned on/off.

The head portion 5 is provided at one end (upper side) of the grip portion 3 and includes a wheel 6 as a first operating member and a trigger 2 (see FIG. 2) as a second operating member.

The wheel 6 is an operation member as a steering for controlling the traveling direction of the controlled body. The wheel 6 is supported by a rotating shaft extending in the direction of the head section 5 of the transmitter 1 perpendicularly to the substantially disc-shaped surface, with the center of the substantially disc-shaped surface aligned with the axis. The wheel 6 is operated as a steering wheel for controlling the traveling direction of the object to be controlled by turning leftward and rightward from a predetermined reference position.

FIG. 2 is a side view of the radio control transmitter shown in FIG. 1 with the small type grip cover 8 removed.
The trigger 2 is an operation member for controlling the power source of the controlled body and controlling the movement speed of the controlled body. As shown in FIG. 2, the trigger 2 has a trigger shape and is divided into a throttle lever 9 as a first lever and a brake lever 10 as a second lever. and is attached to the head portion 5 so as to be rotatable in the direction of the arrow B. As shown in FIG.

The trigger 2 is generally operated by pulling the index finger of the hand holding the grip portion 3 over the throttle lever 9 in the direction of arrow A, and pushing the brake lever 10 with the back of the finger over the throttle lever 9 in the direction of arrow B. manipulated.

The trigger 2 automatically returns to a preset initial position (the state shown in FIG. 2) when the finger on the throttle lever 9 is released. This initial position is called a neutral position. In the neutral position, the engine of the controlled body is rotating, but the clutch is disengaged, and the controlled body does not run.

Note that when the power source of the controlled body is a motor, the motor is not rotating at the neutral position.

The trigger 2 controls the throttle of the engine of the object to be controlled by pulling the throttle lever 9 in the direction of arrow A in FIG. 2, thereby controlling the moving speed of the object to be controlled. The more the trigger 2 operates the throttle lever 9 in the direction of the arrow A, the more the steered object accelerates.

Also, the trigger 2 can control the brake by operating the brake lever 10 in the direction of the arrow B in FIG. The more the trigger 2 operates the brake lever 10 in the direction of the arrow B, the more powerful the brake becomes.

Depending on the settings of the transmitter 1, operating the brake lever 10 of the trigger 2 in the direction of arrow B in FIG. In addition, even when a motor is used to power the object to be controlled, the object to be controlled can be accelerated by operating the throttle lever 9 of the trigger 2 in the direction of arrow A in FIG.

In addition to the wheel 6 and the trigger 2, the transmitter 1 is also provided with many operating members such as buttons. These operation members can be assigned special operations related to the operation of the controlled object.

The head portion 5 is provided with a display portion 11 and a steering antenna 12 . The display section 11 is provided at a predetermined angle so that the operator can easily see the display screen when the grip section 3 is gripped by the operator. The display unit 11 is a display for displaying the settings of the transmitter 1 . By operating setting operation members such as operation buttons and slide switches provided around the display unit 11 , the content of the display can be switched and the transmitter 1 can be displayed. setting is changed.

The steering antenna 12 is located at one end portion of the head portion 5 located on the opposite side of the display portion 11 when the grip portion 3 is gripped by the operator (that is, at one end portion of the head portion 5 when the grip portion 3 is gripped by the operator). rotatably supported at the end opposite to the end facing the operator). The steering antenna 12 is rotated 90 degrees from the horizontal state (the state shown in FIG. 2) where it forms an outer shape integrally with the head unit 5, and is used in an upright state when the object to be controlled is remotely controlled. be. By using the steering antenna 12 in an upright state, it is possible to improve directivity during remote control of the controlled object.

In addition to the display unit 11 described above, the head unit 5 also incorporates an electronic circuit unit (not shown) including a transmission unit (communication module), a storage unit, and a control unit.

The base portion 4 is replaceably provided with a battery for supplying necessary drive power to each portion (the display portion 11, the communication module, the storage portion, and the control portion) of the electronic circuit portion.

The communication module modulates and amplifies the transmission data generated by the controller, and transmits the modulated and amplified steering signal to the controlled object via the steering antenna 12 under the control of the controller.

The storage section stores various setting information based on the operation of the setting operation member under the control of the control section. Further, the storage unit stores a control program for controlling the driving of each unit that constitutes the transmitter 1 .

The control unit integrally controls the display unit 11, the communication module, and the storage unit, generates transmission data according to the operation and setting of the wheel 6 and the trigger 2, controls the display of the display unit 11, and controls the display from the communication module to the steering antenna. 12, stores setting information in a storage unit, and controls driving of each unit of the transmitter 1 based on a control program stored in the storage unit.

The base portion 4 is formed with a larger diameter than the grip portion 3 and provided at the other end (lower side) of the grip portion 3, as shown in FIG. This base portion 4 accommodates a battery.

The grip part 3 has a rear part on the wrist side to be supported and a front part on the finger side. Therefore, the direction along the long axis of the cylindroid shape, which is the cross-sectional shape perpendicular to the axis of the grip portion 3, is the front-rear direction. The grip part 3 has a grip body part 13 . As shown in FIG. 7A, the front half 14 of the grip main body 13 has a slightly larger outer diameter than the rear half 15 at the boundary 16 along the axis. Conversely, the grip main body portion 13 is formed such that the outer diameter of the rear half portion 15 is slightly smaller than that of the front half portion 14 with respect to the boundary portion 16 .

Further, the grip main body portion 13 has a constricted portion 17 having a smaller outer diameter than the other portion at the boundary with the head portion 5 . The back of the constricted portion 17 is in contact with the inter-finger portion between the thumb and index finger. Therefore, the distance from the finger-to-toe portion to the trigger 2 is the shortest in the hand gripping the grip portion 3 with the finger-to-toe portion in contact with the constricted portion 17, so that the index finger can easily reach the trigger 2. - 特許庁

The grip body portion 13 has a step of about several millimeters at the boundary portion 16 . In other words, the boundary portion 16 is a stepped portion that is the difference between the outer diameter of the front half portion 14 and the outer diameter of the rear half portion 15 . A grip cover 8 called a small type in this embodiment is attached to a rear half portion 15 of the grip body portion 13 bordering on the boundary portion 16 .

The grip main body 13 has a ridge 18 (see also FIG. 1) along the longitudinal direction, that is, the direction in which the head portion 5 and the base portion 4 are separated from each other, in the rear half portion 15 to which the small type grip cover 8 is attached. It is formed. A plurality of locking holes 19 are formed at intervals along the boundary portion 16 in the rear half portion 15 of the grip body portion 13 . The locking holes 19 are arranged symmetrically on both sides of the grip main body 13 with the protrusion 18 interposed therebetween.

3(a) is a perspective view of the small type grip cover 8 as seen from the rear, (b) is a perspective view of the small type grip cover 8 as seen from the front, and (c) is the small type grip cover 8. is a side cross-sectional view of the.
The small type grip cover 8 has a figure 7 shape when viewed from the side by a back portion 20 covering the rear half portion 15 of the grip body portion 13 and a curved portion 21 curved backward from the upper end of the back portion 20.例文帳に追加When the grip cover 8 is attached to the grip body portion 13 , the boundary between the bent portion 21 and the back portion 20 is arranged at the constricted portion 17 .

The grip cover 8 has an elongated hole 22 through which the protrusion 18 of the grip body 13 passes. The grip cover 8 weighs about 10 g without the elongated hole 22 . The grip cover 8 is lightened to a weight of about 7 g by providing the long hole 22 . The grip cover 8 is made of elastomer having a thickness of about 2 mm, for example. A slot 22 is formed across the bent portion 21 and the back portion 20 . That is, the long hole 22 overlaps the constricted portion 17 of the grip body portion 13 . The grip cover 8 is attached to the grip main body 13 to cover the rear half 15 of the grip main body 13 facing the palm. One of the characteristics of the small type grip cover 8 is that it has the long hole 22 .

The grip body portion 13 has a crimped surface (see FIG. 1) formed on the penetrating tip surface of the ridge portion 18 . When the grip cover 8 is attached to the grip part 3 , the embossed surface is exposed from the long hole 22 . The grip portion 3 has a non-slip effect due to the exposed textured surface. The grip cover 8 has a non-slip surface. That is, the grip portion 3 has the non-slip surface of the grip cover 8 divided in the circumferential direction. The embossed surface is anti-slip like the surface of the grip cover 8. - 特許庁As for texturing, it has a soft feel that reproduces the feel of an elastomer. Also, unlike a knurled surface, the textured surface has a rougher feel than that of the elastomer surface. Therefore, the grip portion 3 exists so that the non-slip surface of the grip cover 8 and the embossed surface of the ridge portion 18 are continuous in the circumferential direction (see FIG. 7(e)).

The grip body portion 13 has a penetrating tip surface of the ridge portion 18 formed in an arc shape in the circumferential direction. The grip cover 8 is formed in a shape that is not continuous with the penetrating tip surface of the protrusion 18 in the circumferential direction. Accordingly, when the grip cover 8 is attached to the grip main body 13, the groove 29 is formed at the boundary between the penetrating tip surface of the protrusion 18 of the grip main body 13 and the edge of the long hole 22 of the grip cover 8. It is formed.

The grip cover 8 has a plurality of locking claws 23 spaced apart from the edge of the back portion 20 on both sides of the elongated hole 22, the lower edge of the back portion 20, and the upper edge of the bent portion 21, and the grip main body. It is formed toward the portion 13 . These locking claws 23 lock the grip cover 8 to the grip body 13 so as to be unlockable by locking into the locking holes 19 provided in the grip body 13 . In other words, the grip cover 8 is detachably attached to the grip main body 13 by elastically deforming the locking claws 23 .

FIG. 4 is a perspective view of the radio control transmitter with the normal type grip cover 24, viewed obliquely from the rear.
Instead of the small type grip cover 8, a normal type grip cover 24, which is another grip cover, is detachably attached to the grip body portion 13. - 特許庁The normal type grip cover 24 is formed so as to cover the ridge 18 without having the elongated hole 22 and preferably to adhere to the penetrating tip surface, which is the surface of the ridge 18 . When the grip cover 24 is attached to the grip main body 13 , the constricted portion 17 has a diameter larger than that of the small type grip cover 8 by covering the protrusion 18 .

FIG. 5(a) is a perspective view of the normal type grip cover 24 as viewed diagonally from the rear, (b) is a perspective view of the normal type grip cover 24 as viewed diagonally from the front, and (c) is a normal type grip cover 24. is a side cross-sectional view of the.
The normal type grip cover 24 is formed thicker than the small type grip cover 8 . Specifically, the normal type grip cover 24 is made of an elastomer having a thickness of about 2.5 mm, for example. As a result, the grip portion 3 with the normal type grip cover 24 attached has a larger grip diameter than when the small type grip cover 8 is attached. The normal type grip cover 24 has a thicker wall and a larger outer diameter, and is provided with a plurality of cutouts 25 inside to suppress an increase in weight. In addition, the normal type grip cover 24 is provided with a support rib 26 in contact with the grip main body 13 at the boundary with the adjacent lightening part 25 to suppress the decrease in rigidity, that is, when the grip part 3 is gripped, it is compressed. It is difficult to cause deformation. In addition, the normal type grip cover 24 is provided with a plurality of locking claws 23 to be locked in the locking holes 19 in the same manner as the small type.

FIG. 6(a) is a perspective view of the large type grip cover 27 seen from the rear, (b) is a perspective view of the large type grip cover 27 seen from the front, and (c) is the large type grip cover 27. is a side cross-sectional view of the.
In place of the small-type grip cover 8 and the normal-type grip cover 24, a large-type grip cover 27, which is another grip cover, is detachably attached to the grip body portion 13. - 特許庁A large-type grip cover 27 is formed so as to cover the ridge portion 18 without the elongated hole 22 . When the grip cover 27 is attached to the grip main body 13 by covering the protrusion 18, the diameter of the constricted portion 17 becomes larger than that of the normal type grip cover 24. - 特許庁

The large type grip cover 24 is formed thicker than the normal type. Specifically, the large type grip cover 27 is made of an elastomer having a thickness of about 5.5 mm, for example. As a result, the grip portion 3 with the large type grip cover 27 attached thereto has a larger grip diameter than when the normal type grip cover 24 is attached. The large-type grip cover 27 is made thicker and has a larger outer diameter, and is provided with a plurality of lightening portions 25 on the inner side to suppress an increase in weight. Also, in the large-type grip cover 27, a support rib 26 is provided at the boundary between the adjacent recessed portion 25 and is in contact with the grip main body 13 to suppress a decrease in rigidity. It is difficult to cause compression deformation. In addition, the large type grip cover 27 is provided with a plurality of locking claws 23 to be locked in the locking holes 19 in the same manner as the small type.

In other words, in addition to the small type grip cover 8, the normal type grip cover 24 and the large type grip cover 27 can be selectively attached to the transmitter 1. As shown in FIG.

As shown in FIG. 7(a), the constricted portion 17 is formed with a concave portion 28 corresponding to the trigger 2 and serving as an escape when the trigger 2 is pulled, in the front half portion 14 on the side opposite to the ridge portion 18. there is In the sectional views of the grip covers shown in FIGS. 7(b), (c), and (d), the distance from the locking claw 23 to the rear end is small type (8), normal type (24), and large type. (27) increases in order. As a result, in the constricted portion 17 with the grip covers attached, as shown in FIG. d3 of the large type grip cover 27 increases in order (d1<d2<d3).

FIG. 8 is an explanatory diagram comparing the distance in the longitudinal direction of the constricted portion 17 of the radio control transmitter, which differs for each type of grip cover.
As a result, when the grip covers 8, 24, and 27 are attached, the constricted portion 17 in the grip portion 3 has a major axis length of d2=44 mm in the cylindric shape of the normal grip cover 24, and d2=44 mm in the large type grip cover. 27 has d3=47 mm, and the small type grip cover 8 has d1=41 mm. In other words, by exchanging each grip cover, the transmitter 1 can be changed to the side opposite to the position (recess 28 in FIG. 7) where the trigger 2 is placed across the grip part 3 (the two-dot chain line in FIG. 8). three-dot chain line) can be changed. As for the weight, the small type grip cover 8 for children is about 7 g, the normal type grip cover 24 is about 10 g, and the large type grip cover 27 is about 15 g.

Next, the operation of the configuration described above will be described.

In the transmitter 1 according to this embodiment, the grip portion 3 has the grip body portion 13 to which the head portion 5 is connected at one end and the base portion 4 is connected at the other end. The grip main body portion 13 has rigidity as a structure capable of supporting both the head portion 5 and the base portion 4 . The grip main body portion 13 is formed with a ridge portion 18 along the longitudinal direction on the inter-finger side between the thumb and the forefinger. The half of the grip main body 13 on the side where the ridges 18 are provided serves as the rear half 15 with which the inter-finger portion is in contact.

A grip cover 8 having an elongated hole 22 through which the ridge portion 18 passes is attached to the rear half portion 15 of the grip body portion 13 . The grip part 3 is gripped by the user with the grip cover 8 attached. The grip cover 8 has an elongated hole 22 through which the protrusion 18 penetrates so that the material of the portion corresponding to the protrusion 18 is reduced. That is, the weight is reduced by that amount.

In the transmitter 1, since the grip cover 8 made lighter by the long hole 22 is detachably attached to the grip main body 13, the entire grip unit can be replaced according to the size and thickness of the grip part like the conventional one. This eliminates the need for a highly rigid and heavy detachable fixing structure. That is, the lightweight and compact grip cover 8 can be detachably attached with a simple locking structure using the locking claws 23 and the locking holes 19 .

In addition, since the inter-finger portion of the grip cover 8 is in contact with the penetrating tip surface of the protrusion 18 penetrating the elongated hole 22 of the grip cover 8, the direction is the same as when the grip cover 8 is not attached. becomes. Most importantly, the distance between the index finger and the trigger 2 can be minimized. This makes the grip part 3 optimal for users with small hands, such as children with small grip diameters. Specifically, even children aged 4 to 5 can operate the trigger 2, making the transmitter 1 very easy to hold.

Here, in the transmitter 1, in order to make the grip part 3 thin, the inside of the grip part becomes narrow. In other words, if a user with small hands is used as a standard and a thin structure for assembling a grip cover that covers the rear half 15 of the grip part 3 is used as a standard, the thickness of the elastomer must be increased in the order of the normal type and the large type. In other words, if the structure d2 in FIG. 7(e) is used as a thin type without having the elongated hole 22 like the grip cover 8, d3 in FIG. The type consists of thin, standard, and thick elastomer grip covers covering the grip portion 3, and the thick-sized grip considerably increases the weight. Heavy transmitters are less valuable because they are out of the user's options. For this reason, the grip cover is based on the normal type, which is one step smaller (thinner), and a small type that has a structure with an elongated hole 22 to reduce the thickness is added to the size variations. Since the large type can be made one step larger (thicker) than the normal type, the increase in the thickness and weight of the elastomer can be suppressed compared to when the small type is used as the standard. The structure of the grip main body 13 based on the small type has a protrusion 18 corresponding to the elongated hole 22, so that wiring and a substrate can be configured inside and to maintain the rigidity of the grip itself. Therefore, the original function of the grip portion is not degraded.

In this transmitter 1 , when the grip cover 8 is attached to the grip main body 13 , the embossed surface on the penetrating tip surface of the projection 18 penetrating the elongated hole 22 of the grip cover 8 is exposed. The material of the grip cover 8 is, for example, an elastomer. A non-slip is provided on the surface of the grip cover 8. - 特許庁As a result, when the grip cover 8 is attached to the grip main body 13, the grip cover 8 has a rubber-like texture, so that it can be comfortably gripped (grasped) and a good steering feeling can be obtained. When the grip cover 8 is attached to the grip part 3 , the grip cover 8 is positioned on both the left and right sides of the protrusion 18 . Two anti-slip actions, i.e., anti-slip action by the textured surface of the part 18, can be obtained as a continuous surface on the grip part 3. - 特許庁As a result, the embossed surface of the protrusion 18 exposed from the elongated hole 22 of the grip cover 8 prevents slippage, and even a user with small hands can firmly grip the grip cover.

A groove portion 29 is formed at the boundary between the penetrating tip surface of the protrusion portion 18 of the grip body portion 13 and the long hole 22 of the grip cover 8 . Due to the presence of this groove portion 29, when the user grips the grip portion 3, a gap is generated between the user's hand and the grip portion 3, and ventilation can be ensured. As a result, even users whose hands are prone to perspiration, such as children's hands, can firmly grip without slipping.

In the transmitter 1, the grip cover 8 and other grip covers 24 and 27 are detachably and selectively attached to the grip main body 13. As shown in FIG. As described above, the grip cover 8 has a finger-to-toe portion in contact with the penetrating tip surface of the protrusion 18 penetrating the elongated hole 22 of the grip cover 8, so that the grip cover 8 may not be attached in that direction. It is the same and can be optimized for users with small hands with small grip diameters, such as children. On the other hand, the other grip covers 24 and 27 do not have the elongated hole 22, and the thickness of the portion covering the protrusion 18 is increased, so that the distance in the direction in which the finger-to-toe portion contacts is increased. diameter increases. Thereby, the user can select either the grip cover 8 or the other grip covers 24 and 27 to change the grip diameter and adjust the optimal grip condition. As a result, it is possible to change the color, design (pattern), touch/grip (softer/harder, etc.) while suppressing an increase in the overall weight of the transmitter. In addition, it is possible to replace it due to aging deterioration, staining, etc., and to replace it with a limited color version.

A small type grip cover 8, which is a transmitter grip cover according to the present embodiment, is mounted so as to cover the grip main body 13 by penetrating the elongated hole 22 through the projection 18. As shown in FIG. The material of the grip cover 8 corresponding to the protrusion 18 is reduced, and the weight is reduced accordingly.

Since the finger-to-toe portion of the grip cover 8 touches the penetrating tip surface of the protrusion 18 penetrating the long hole 22 of the grip cover 8, the direction is the same as when the grip cover 8 is not attached. That is, the grip cover 8 can be attached based on the diameter of the constricted portion 17 of the grip main body portion 13 . Thereby, the distance between the index finger and the trigger 2 can be minimized. The minimum diameter of the constricted portion 17 is the outer diameter required for forming wiring and substrates inside the grip portion 3 and for maintaining the rigidity of the grip itself, which corresponds to the small size. As a result, by attaching the small type grip cover 8 to the grip portion 3, the grip portion 3 can be optimized for users with small hands and children with small grip diameters.

Therefore, according to the transmitter 1 of the present embodiment, the grip portion 3 having a small grip diameter can be realized while suppressing an increase in the weight of the transmitter as a whole. In other words, a grip cover 8 made of elastomer or the like and having a non-slip function can be provided on a part of the peripheral surface of the grip portion 3 having a necessary rigidity and a small diameter.

According to the transmitter grip cover (small type grip cover 8) according to the present embodiment, it is possible to deal with the small-diameter grip portion 3 while suppressing an increase in the weight of the entire transmitter.
