Description

ADJUSTABLE SPEAKER BOX FOR THE SPORTS BAR
OF A VEHICLE
BACKGROUND OF THE INVENTION
1. Field of the Invention. This invention relates to the field of speaker boxes for sort utility vehicles and more particularly to the field of speaker boxes mountable to the sports bar of such vehicles.

2 Discussion of the Backaround. Speaker boxes are commonly mounted to the sports bar of sport utility vehicles to provide music and other audio entertainment for the driver and passengers.
Currently, such speaker boxes are mounted to extend across the sports bar in a fixed, horizontal position. In use, the sound from the speakers is then only directed downwardly and cannot be adjusted. At outdoor parties or other gatherings in which it is desirable to use the speakers to provide entertainment to the people gathered around the vehicle (such as at a campsite or on the beach), this can be a drawback. That is, because the speakers are fixed in place and their sound is directed downwardly into the deck or cabin area of the vehicle, the music or other audio heard by the party Boers around the vehicle is often muted and distorted.

With this and other drawbacks in mind, the present invention was developed. With it, an arrangement is provided for pivotally mounting the speaker box to the sports bar so the sound from the speakers can be directed as desired. In one position, the sound can be directed downwardly as in current designs. However, unlike current designs, the speaker box of the present invention can also be positioned to direct its sound to the rear of the vehicle or even slightly toward the front of the vehicle if desired. In the rearwardly facing position, the sound is delivered without obstruction to the people gathered behind the vehicle. In the slightly forward position, the sound from the speaker box of the present invention is clearer to the driver and front passengers as they travel in the vehicle. In this forward position, a saddle or cutout is provided in the middle section of the speaker box so the driver can still clearly see passed the speaker box through the rear view mirror.

SUL~lARY OF THE INVENTION
This invention involves a speaker box for a sport utility vehicle. The speaker box is pivotally mounted to the sports bar of the vehicle and can be selectively pivoted relative to the bar to a plurality of positions. In one position, the sound from the speakers of the speaker box is directed downwardly as in convention designs. However, unlike conventional designs, the speaker box and its l0 sound can also be directed rearwardly of the vehicle for parties and other gatherings such as at campsites or on the beach. Further, the speaker box and its sound can be directed slightly forward toward the front of the vehicle if desired. In doing so, a saddle or cutout is provided in the middle of the speaker box so as not to unduly inhibit the driver's vision through the rear view mirror.

DETAINED DESCRIPTION OF THE INVENTION
As shown in Figures 1 and 8, the dual speaker box 1 of the present invention is mounted on the sports bar 2 of the vehicle 4 for pivotal movement to a variety of positions. Normally, the speaker box 1 is supported substantially horizontally in the position H as shown in solid lines in Figure 8.
However, with the present invention, the speaker box 1 can be pivoted to a number of other positions as desired including the up or vertical position V_ illustrated in Figure 1.
In the vertical position V of Figure 1, the high frequency speakers 3 and mid-frequency/bass ports 5 of the speaker box 1 as well as the dome lights 6 are directed substantially rearwardly of the vehicle 4. In contrast and in the normal horizontal position H of Figure 8, the high frequency speakers 3 and mid-frequency/bass ports 5 of the speaker box 1 as well as the dome lights 6 are directed substantially downwardly. In doing so, the speaker box 1 as shown in full lines in Figure 8 then assumes an essentially out-of-the way location for maximum use of the interior space of the vehicle 4. This position H also permits any removable soft or hard top to be placed on the vehicle 4. However, with the pivoting arrangement of the present invention as indicated above, the speaker box 1 is not limited to this horizontal position H in Figure 8 as in conventional designs. Rather, the speaker box 1 of the present invention can be adjusted, for example, to the up or vertical position V in Figures 1 and 2 to direct the sound from the box 1 rearwardly of the vehicle 4. This is a particularly desirable option for outdoor parties and gatherings at campsites, the beach, and similar locations as the sound can be directed in an unobstructed manner at the party Boers. That is, instead of having the sound directed primarily downwardly into the deck 8 and/or cabin area 10 of the vehicle 4 as in conventional designs and be somewhat muted and distorted, the speaker box 1 can be pointed directly at the gathering to deliver a clear and unobstructed sound to the party Boers.
To accomplish this, the speaker box l as shown in Figure 2 is mounted by the adjustable mechanism 9 to the sports bar 2. As perhaps best seen in the partially cutaway view of Figure 3 and in the side view of Figure 4, the adjustable mechanism 9 includes a plate member 11 on each of its sides that is fixedly attached by a C-clamp 13 (see Figure 4) to the sports bar 2. A rod member 15 is then provided on each half of the adjustable mechanism 9 as shown in Figure 3. Each rod 15 is mounted in the channel 17 in the speaker box 1 for sliding movement along the collinear, longitudinal axes 19 of the rods 15. More specifically as illustrated in Figure 3, the rods 15 are hollow along part of their lengths and are concentrically mounted on the inner post member 21. In this manner, the coil spring 23 can be positioned as shown to bias the two rods 15 apart to the position of Figure 3. Referring to the left side of Figure 3 and as is explained in more detail below, the two detents 25 on the cross piece 27 in this view are engaged in the corresponding pair of holes 29 in the fixed plate 11 (see also Figure 4). The speaker box 1 is then firmly secured in the up or vertical position v_ of Figures 1-4 with the speakers 3 and ports 5 as well as the dome lights 6 (see Figure 1) facing rearwardly of the vehicle 4.
Each rod 15 as shown in Figure 5 has a handle 31 extending outwardly of the rod 15 and its axis 19. This handle 31 as illustrated sticks through the opening at 33 in the speaker box 1 so the handles 31 can be manually grasp and manipulated to adjust the mechanism 9. More specifically and in operation as best seen in reference to Figures 3 and 6, the pair of handles 31 can be manually squeezed together in the direction of arrows 35 in Figure 6.
This movement slides the rods 15 together and withdraws or disengages the detents 25 on the respective cross pieces 27 from the holes 29 .in each fixed plate 11 (see Figure 6). In this withdrawn or disengaged position of Figure 6, the speaker box 1 can be rotated about the axis 19 toward a second position such as the horizontal position H shown in full lines in Figure 7. Releasing the handles 31 will then bias and move the cross pieces 27 (which are fixed to the respective rods 15) outwardly under the force of the spring member 23. Once the detents 25 on each cross piece 27 are rotated to be aligned with the horizontal pair of holes 29' in each plate 11 as illustrated in Figure 7, the detents 25 will move or snap outwardly to be received in the horizontally spaced holes 29'. In this manner, the speaker box 1 is then firmly secured in the horizontal position H of Figure 7.
It is noted as illustrated in Figures 3-4 and 6-7 that the speaker box 1 is mounted by support pins or members 37 on the respective rods 15. The main body of each support member 37 (see Figures 3 and 6) is positioned between the plate member 11 on each side of the speaker box 1 and the respective cross piece 27. In operation to rotate the speaker box 1 about the axis 19 from the position of Figure 3, the detents 25 are withdrawn or disengaged (see Figure 6) not only from the pair of holes 29 in the respective plate 11 but also from the aligned pair of holes 39 in the respective support member 37.
The support member 37 on each side and the respective rod 15 are not fixed to each other and the rods 15 as shown in Figures 3 and 6 can slide along the axis 19 relative to the support members 37. However, the rotation of the speaker box 1 about the axis 19 will move both the support members 37 and the rods 15 (as well as the cross pieces 27 fixed to the rods 15) . The rods 15 with the cross pieces 27 and detents 25 are thus the catch and release arrangements to firmly secure the support members 37 of the speaker box 1 to the respective plate members 11. The plate members 11 in turn are then fixedly attached to the sports bar 2 as discussed above. In this regard, each support member 37 and each arrangement of rod 15, cross piece 27, and detents 25 are thus respectively engagable and disengagable with the respective plate member 11.
5 In the preferred embodiment, the speaker box 1 is adjustable to assume at least the three positions shown in Figure 8. In the up or vertical position _V, the sound from the speaker box 1 as indicated above is directed rearwardly of the vehicle 4. In 10 the horizontal position H shown in full lines in Figure 8, the speaker box 1 is directed downwardly as in conventional designs. This places the speaker box. 1 as discussed above in an out-of-the-way position for maximum use of the interior space of the vehicle 4. It also enables a removable soft or hard top to be placed on the vehicle 4. The third or forward position _F illustrated in Figure 8 shows the speaker box 1 at about a 30 degree angle from the horizontal position H. In this position _F, the speaker box 1 is facing slightly toward the front of the vehicle 4 to direct the sound from the speaker box 1 slightly forward for more enjoyment by the drive and front passenger in the cabin area 10.
This movement of the speaker box 1 to position _F
from position _H is accomplished as illustrated in Figure 9 in the same manner as the movement from position V_ to position H was described above. In the position F_, the detents 25 are then engaged in the pair of holes 29" in the plate 11. The pair of holes 29" as shown are spaced from and about the rotational axis 19 of the rod 15 as are the respective pairs 29' and 29 as illustrated in Figures 4 and 7. The pairs of holes are for additional strength and there could be just a single set of holes 29, 29', and 29" in each plate 11 if desired. Similarly, each support member 37 for the speaker box 1 preferably has two holes 39 selectively alignable with the pairs of holes in each plate 11 but the support member 37 could have only a single hole 39 spaced from the rotational l0 axis 19 and selectively alignable with the holes in the plate 11 if desired. Each cross piece 27 in this regard is also preferably provided with a pair of detents 25 but a single one could be used. If so, the cross piece 27 would then only need to extend in one direction outwardly of the axis 19 of the rod 15.
Referring again to Figure 8 and in the slightly forward facing position F shown in this view, it is important that the speaker box 1 not unduly inhibit the vision of the driver through the rear mirror 12 along the path 14. To accomplish this, the speaker box 1 as illustrated throughout (e.g., see Figure 2) is preferably provided with a recessed middle portion 41. This saddle or cutout portion 41 as best seen in Figure 10 enables the driver to still see passed the speaker box 1 out the rear of the vehicle 4 with the speaker box 1 in the forward position _F. In this regard, the recessed middle portion 41 extends outwardly of the pivotal axis 19 for a distance less than the distances the spaced-apart side sections 43 do. With both the rear mirror 12 and recessed middle portion 41 of the speaker box 1 centrally located across or transversely of the vehicle 4, the recessed middle portion 41 then permits the driver to still see rearwardly of the vehicle 4 through the rear vision mirror 12 with the speaker box 1 in the forward position F.
It is noted that an additional safety feature is provided in the adjustable mechanism 9 to stop the speaker box 1 from pivoting too far forward.
This feature is best illustrated in Figure 9 in which a stop post 45 is provided on each fixed plate 11 (see also Figure 3). In operation and should the speaker box 1 inadvertently fall or slip passed the desired position _F in Figure 9, the support member 37 for the speaker box 1 will abut and be stopped by the post 45 in the safety position S of Figures 9.
With certain modifications to the preferred design of the speaker box 1 (e.g., reducing the size of the recessed middle portion 41 and/or the entire size of the speaker box 1 including the sections 41 and 43), the speaker box 1 may be allowed to swing to a position facing directly toward the front of the vehicle 4 and the driver still be able to see passed it. However, it is preferred that the downward rotation of the speaker box 1 be limited as disclosed above.
Referring to Figure 11, the pivotal movement of the speaker box 1 about the horizontal axis 19 could be done by using a power drive if desired such as the simple gear motor arrangement 51 of Figure 11.

The motor 51 could then be remotely controlled by an electronic actuator or switch 53 located in the vehicle cabin 10 as schematically illustrated in Figure 11. The motor 51 could also be remotely controlled by radio or other electromagnetic waves received by the antenna 55 from a generating source or actuator that was in the cabin 10 or part of a portable, handheld unit such as 57. The portable unit 57 in this regard could additionally be used to remotely control the volume and other operations of the speaker box 1. The speaker box 1 could also be mounted as illustrated in Figure 12 for pivotal movement about a vertical axis 59 in place of or preferably in addition to the horizontal axis 19.
Such movement as in Figure 11 could be remotely controlled if desired from within the vehicle cabin 10 or from a location outside the vehicle 4.
Figure 13 is a cross sectional view of the speaker box 1 illustrating the mid-frequency resonance chamber 61 on each side and the surrounding resonance chamber 63 for the bass or lower frequencies. As shown, both the mid-frequency and bass are directed to exit the speaker box through the respective ports 5. The enlarged and curved horn of each resonance chamber 63 has been found to particularly enhance the quality of the bass sounds from the speaker box 1.
while several embodiments of the present invention have been shown and described in detail, it to be understood that various changes and modifications could be made without departing form the scope of the invention.
