The present disclosure relates to a system for mounting body components to model vehicles. More particularly, the present disclosure relates to structures for mounting body components to model vehicle frames such as radio-controlled model airplanes, helicopters, cars, and boats.
Model vehicles are used in leisure and hobby activities. Body mounting systems are used to mount body structures and components to vehicles for aerodynamic or aesthetic purposes.
According to the present disclosure, a system for mounting body components to model vehicles includes a model vehicle frame, a body component, and a body mounting apparatus. Body mounting apparatus is used to couple the body component to the vehicle frame so that the body component covers a portion of the vehicle frame.
Illustratively, the body mounting apparatus includes a mounting member coupled to the vehicle frame, a connector post coupled to the mounting member, and a body support flange. The body support flange is adapted to be coupled to the body component and to mate with a portion of the connector post to enable pivotable movement of the body support flange relative to the connector post.
In an illustrated embodiment, one end of the connector post is formed to include a hole receiving a free end of the mounting member therein to anchor the connector post in a fixed position relative to the vehicle frame. An opposite second end of the connector post includes a ball that is located in a socket formed in the body support flange to establish a “snap-fit” universal joint allowing motion of the body support flange relative to the anchored connector post. Such motion enables a user to move the body support flange relative to the anchored connect post to engage an inner wall of the body component. An adhesive is used to retain the body support flange in mating engagement with the inner wall of the body component.
Additional features of the disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
The detailed description refers particularly to the accompanying figures which are drawn to scale in which:
According to the present disclosure, a body mounting system 10 for model vehicles includes components that can be coupled to a vehicle frame 16 and a vehicle body 30 and located in a chamber provided inside vehicle body 30. Body mounting system 10 is configured to allow rapid mounting and dismounting of body shell components 30 to vehicle frame 16 as shown, for example in
Body mounting system 10 includes a mounting member 24, a left-side body-mount fixture 11a, and a right-side body-mount fixture 11b. In the illustrated embodiment, each body-mount fixture 11a and 11b includes a connector post 12 and a body support flange 14 as shown, for example, in
Connector post 12 includes a mounting member-receiving first end 18 and a ball-shaped second end 20. Connector post 12 is generally hollow with a connector post through-hole 22 passing from first end 18 through a center of connector post 12 to second end 20. Through-hole 22 is arranged to receive threaded mounting member or stud 24 which extends through vehicle frame 16 and couples to an interior surface of through-hole 22 to form a threaded surface thereon. A blind hole (not shown) could also be used. Connector post 12 is generally square or polygonal in cross-section to facilitate the gripping of connector post 12 by hand tools such as pliers or wrenches so that connector post 12 can be coupled to threaded stud 24 easily. Illustratively, connector post 12 can be mounted in pairs on opposite sides of vehicle frame 16 to form a multi-connector post mounting system.
Body support flange 14 includes a ball-receiving socket 26 formed to include an annular lip 27 and “petal-shaped” mounting plates 28. Mounting plates 28 are able to deflect relative to one another to mate with a non-flat or otherwise irregular surface of body component 30 of a model vehicle as shown, for example, in
Illustratively, connector post 12 and body support flange 14 are constructed of a molded plastic material such as, for example, nylon, acetal, polyurethane, or polycarbonate. In other embodiments contemplated by this disclosure, connector post 12 is made of injection-molded nylon or acetal plastic for stiffness. Body support flange 14 is made of injection-molded polycarbonate plastic because polycarbonate plastic is physically strong and compatible with the adhesives used in coupling socket flange 14 to body component 30. In yet another embodiment, connector post 12 is made of injection-molded flexible polyurethane plastic so that connector post 12 can flex when high loads are applied to body component 30, for example, during a crash of a model helicopter 36, as shown in
Connector post 12 is arranged to be coupled to threaded stud 24 for perpendicular alignment of connector post 12 relative to vehicle frame 16. Threaded stud 24 passes through an aperture 38 in vehicle frame 16 and extends into through-hole 22 in connector post 12 as shown, for example, in
Ball-receiving socket 26 is pressed over ball-shaped second end 20 of connector post 12 whereupon annular lip 27 of ball-receiving socket 26 expands elastically and radially outwardly from a center of ball-receiving socket 26 to receive ball-shaped second end 20 into ball-receiving socket 26, and then contracts radially inwardly toward the center of ball-receiving socket 26 to surround ball-shaped second end 20 to form a “snap-fit” connection, thereby coupling body support flange 14 to connector post 12. Body support flange 14 is arranged to pivot about axis 19 on ball-shaped second end 20 of connector post 12, and is further arranged to tilt through a pivot angle 40 of about plus or minus 30 degrees relative to a back-plane 42 before annular lip 27 contacts a side of connector post 12.
Illustratively, the present disclosure is shown for use on a model helicopter 36 as shown, for example, in
Model helicopter 36 includes a main rotor 44 and a tail rotor 46 driven by a power source 48 as shown, for example, in
In addition to body component 30, vehicle frame 16 supports, for example, vehicle systems 39, as shown in
Illustratively, when mounted on helicopter 36, body component 30 is an aircraft canopy arranged to cover a portion of vehicle frame 16. In some embodiments, body component 30 is configured in a variety of other shapes. In the illustrated embodiments, body component 30 is shown as a typical model helicopter canopy. Body component 30 can also be arranged as a scaled-down, man-carrying helicopter. In such arrangements, body component 30 is a “scale canopy,” and is configured to present the appearance of a full-sized helicopter.
Connector posts 12 are anchored to vehicle frame 16 to support body component 30 as shown, for example, in
To locate body component 30 in a fixed position relative to vehicle frame 16, body component 30 is moved in a direction 66 over a front end 17 of vehicle frame 16 until each body support flange 14 is in position adjacent to its associated connector post 12 as shown, for example, in
Body component 30 is removed from vehicle frame 16 in a similar fashion. A force is applied in the opposite of direction 68 to the inside surface of body component 30 near each body support flange 14 to cause each annular lip 27 of ball-receiving socket 26 to expand radially outwardly from the center of ball-receiving socket 26 to release ball-shaped second end 20, and allow body component 30 to move away from vehicle frame 16, as suggested in
Body support flange 14 is able to snap-fit onto connector post 12 at pivot angle 40 of about plus or minus 30 degrees, as suggested in
Connector post 12 is designed to be adaptable to different vehicle frames and body components. Each connector post 12 further includes a set of trimming marks 13 and is generally constructed of a plastic material at a length longer than required for any particular model. Trimming marks 13 are molded on the surface of connector post 12. To adjust the length of connector post 12, a sharp instrument (e.g. hobby knife 15) is used to cut away an excess portion of connector post 12 at one of the trimming marks 13, as illustrated in
In some embodiments, connector post 12 further includes cross holes 70, mounting bolts 72, and spacers 74. Cross holes 70 are configured for mounting other components of a model vehicle such as, for example, guards and wiring harnesses. It will be appreciated that connector post 12 can be arranged to have cross holes 70 located along its entire length and configured to receive mounting bolts 72 as shown, for example, in
In one embodiment contemplated by this disclosure, connector post 12 is mounted to vehicle frame 16 using cross holes 70. Spacers 74 are arranged to separate post 12 from vehicle frame 16 so as to position or offset connector post 12 to any desired location relative to vehicle frame 16.
Body mounting system 10 further includes connector posts 12 with a like number of mounting bolts 72 or threaded studs (not shown), washers 76, and body support flanges 14, as shown in
Illustratively, body mounting system 10 includes four connector posts 12 and four body support flanges 14 although kits containing other numbers of connector posts 12 and body support flanges 14 are anticipated as shown, for example, in
In some embodiments it may desirable to use a hard, stiff connector post 12 to rigidly mount a body component 30 wherein connector post 12 is almost certain to break in the event of a crash. Thus, connector post 12 is considered to be disposable.
The illustrative embodiment has multiple posts, adjustable post lengths, adjustable post orientations, adjustable socket angles, flexible body support flanges, and is compatible with many adhesive systems. Thus, it can adapt to most body components and vehicle frame styles, and mount most body components to most frame structures.
It may be desirable to configure connector post 12 to release from body support flange 14 during a crash of a model vehicle such as helicopter 36 so as to reduce damage to connector post 12 and body component 30. When force is applied to body component 30 as when, for example, helicopter 36 crashes, connector post 12 is configured to deform or otherwise bend away from the force until the angle between connector post 12 and body support flange 14 exceeds the maximum socket pivot angle 40 so that body support flange 14 uncouples from connector post 12 without breaking. Since body shell component 30 is often thin and flexible, flexing of body component 30 near connector post 12 effectively increases pivot angle 40 and encourages body flange 14 to disengage from ball-shaped second end of connector post 12.
Unlike simple toys which have few operational requirements, radio-controlled model vehicles are configured to operate realistically. Cars are designed to drive. Airplanes and helicopters are designed to fly. Such operational models have design challenges not found in toys. Thus, it may desirable on many types of models to remove all or part of body component 30 at various times to access components such as radio system components and batteries mounted to vehicle frame 16.
Illustratively, connector post 12 is flexible to resist damage in the event of a crash of the model vehicle which applies unusual forces to body component 30. Multiple connector posts 12 are provided to support large body components such as the canopy of a model helicopter. In some embodiments, connector post 12 further includes means such as cross-holes and brackets for mounting other model components such as guards.
With respect to body mounting system 10, mounting member 24, connector post 12, and body support flange 14 cooperate to provide means for removably coupling body component 30 to vehicle frame 16. Mounting member 24, connector post 12, and body support flange 14 also cooperate to provide means for body support flange 14 allowing pivotable movement of body support flange 14 about axis 19 relative to connector post 12.
