This invention relates to a single control horn and more particularly to a single pull control horn which has a control arm that may be used to control the movement of a component of a radio-controlled vehicle having a center line.
In the remote control field, control arms and the like are often used to control the movement of various components or pieces of equipment. Mounting of such a control arm can create a difficult problem.
For example, a control rod will often be used to control the movement of a rudder used on a remote control airplane. However, because the outer surface of the rudder is angled, securing a control arm so that it is perpendicular to the center line of the component is often difficult. This is so because the clamping members used with a control arm are only designed to work on flat surfaces. Thus, when an angled surface is encountered, the clamping members cannot either fully engage the surface. Neither is it permitted for the clamping member to dig into the surface, as is often the case.
Many times, shims or inserts are used to overcome the problem of attaching the control arms to an angled surface. However, the shims or inserts upset the balance of the remote control vehicle. Thus, there are advantages to avoiding shims or inserts.
Among the many objectives of this invention is the provision of a single pull control horn for a remote control vehicle.
A further objective of this invention is the provision of a single pull control horn for a remote control vehicle adapted to be securely attached to a curved surface.
Yet a further objective of this invention is the provision of a single pull control horn with a clamping member which can fully engage the surface.
A still further objective of this invention is the provision of a single pull control horn with a clamping member which can avoid digging into the surface.
Yet another objective of this invention is the provision of a single pull control horn with a clamping member which can avoid the use of a shim on the surface.
Still, another objective of this invention is the provision of a single pull control horn with a clamping member which can avoid the use of an insert on the surface.
These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a single pull control horn which has a control arm that may be used to control the movement of a component of a remote or radio-controlled vehicle having a center line, and which control arm includes a base member mounted on a threaded rod.
These and other features, objects and advantages of the present invention will become apparent from the following description and drawings wherein like reference numerals represent like elements in several views and in which:
Throughout the figures of the drawings, where the same part appears in more than one figure of the drawings, the same number is applied thereto.
The present invention permits the use of single pull horn with a control arm fitting on an angled surface by providing clamping members that have movable portions. The moveable sections conform to the angle of the support surface so as to maintain the control arm perpendicular to the center line of the component.
The present invention relates to a novel single control horn for use with remote-controlled apparatus including, but not limited to, aircraft, water craft, and land vehicles. More specifically, the present invention provides a base member that maintains a control rod in a position that is perpendicular to a central axis no matter the angle of the outer surface of the component to be controlled
This control arm may be used to control the movement of a component of a remote or radio-controlled vehicle having a center line. The control arm includes a threaded rod as well as a base member. One short clamping member is positionable on each of the opposing sides of the component surface. Each short clamping member has a planar surface and an opposingly located raised section; that, in turn, has an outer surface being partially spherical in shape.
An opening is located in each of the clamping members which extends through the clamping members. Also provided is a locking member, having a cavity shaped to engage the spherical section of the clamping member and an internally threaded bore which coacts with the threaded rod. The coaction between the threaded portions creates a biasing force which urges the base members against the components. The engagement of the cavity and spherical section permit the base member to be moveable with respect to the locking member so as to maintain the threaded rod perpendicular to the centerline of the component, even though the outer surface of the component may not be perpendicular to that centerline.
As shown in
Threaded gripping rod 118 includes a male threaded rod member 120 permanently or releasably secured to a cap nut 126. Cap nut 126 permits threaded gripping rod 118 to be applied as desired to the single pull horn 100 in a desired position at threaded rod member 120.
Adding
With the further consideration of
Once threaded gripping rod 118 is in position through component 104, a second base member 122 is inserted over threaded gripping rod 118 as shown in
As also shown in
As shown in
The base member 122 has a planar surface 142 and an opposingly located raised section 148 that has an outer surface 150 that is partially spherical in shape. A base opening 156 is located in each of the base member 122 which extends through the base member 122.
Also, provided is a locking member 132 on component 104. Locking member 132 has a locking cavity 140 shaped to engage the spherical outer surface 154 of the clamping member 122 and an internally threaded bore 136, which coacts with the threaded gripping rod 118. The coaction between the threaded portions creates a biasing force which urges the base members against the component 104. The engagement of the cavity 138 and spherical section 138 permit the base member 122 to be moveable with respect to the locking member 132, so as to maintain the gripping rod 118 perpendicular to the centerline of the component 104.
Cooperating with the threaded locking member 132 on the topside 160 of component 104, and on the bottom side 162 of component 104, is open locking member 164. Open locking member 164 has an open side 166 adjacent to a second base or clamping member 122 on bottom side 162. Open side 166 has a trapezoidal shape 170 in order to permit cooperation with raised section 148 of clamping member 122 located on bottom side 162.
Cap nut 126 applies threaded rod member 120 of threaded rod 118, forces open locking member 164 to open and abut against clamping member 122, and cooperates with threaded locking member 132 in order to position threaded gripping rod 118. With threaded gripping rod 118 thus positioned control arm 110 can be applied thereto in threaded relation therewith. If desired, holding nut 172 can be positioned between control arm 110 threaded locking member 132 for additional holding power.
This application; taken as a whole with the abstract, specification, claims, and drawings being combined; provides sufficient information for a person having ordinary skill in the art to practice the invention as disclosed and claimed herein. Any measures necessary to practice this invention are well within the skill of a person having ordinary skill in this art after that person has made a careful study of this disclosure.
