DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, Figure 1 illustrates a clamping and holding device 10 comprising a first clamping arm 12 with a general C shape. A second clamping arm 13 is pivotally mounted at one end of the first clamping arm 12.
Clamping arms 12 and 13 cooperate to engage an article upon which the clamping and holding device is to be mounted, such as for example, a section of an arm of a lawn chair illustrated at 14.
A holder 15 which may be in form of a tube with an interior diameter of about one inch is mounted on the first clamping arm 12 to extend laterally from the first clamping arm 12. As shown in Figure 2, holder 15 is mounted for pivotal movement about a horizontal axis transverse to the clamping arms 12 and 13. As shown in Figure 2, holder 15 has a mounting portion 16 which is conical with the smaller diameter close to holder 15. A retaining lip 17 is at the far end of mounting 16 to prevent it from being fully retracted from the first clamping arm 12. A serrated collar 18 is also provided having teeth 19 to permit the holder to be locked firmly in position at a variety of different angles. Upon assembly of holder 15 with main body 10 as shown in Figures 3, 4 and 5, a compression spring 20 urges locking button 21 against conically shaped mounting 16 to urge teeth 19 into engagement with teeth 22 in first 7 212~ 1.6 clamping arm 12. This structure provides a firm engagement between the holder 15 and the first clamping arm 12 at a variety of positions. However, the angular position of holder 15 can readily be adjusted by pulling holder 15 out in a downward direction with respect to Figure 5 to disengage teeth 19 and 22 and permit pivotal rotation.
A locking button 23 is also controlled by spring 20 and it provides a cam follower for engagement with a cam 24 shown in Figure 5. Cam 24 is secured in position within clamping arm 13 by pin 25 which engages locking button 26.
The interaction of cam 24 and cam follower 23 causes clamping arm 13 to be biased into a closed position to hold the article of furniture such as 14 between the clamping arms 12 and 13.
A locking arm 90 may also be pivotally mounted on the first clamping arm 12 to prevent inadvertent opening of the second clamping arm 13 from the closed position as shown in Figure 12. The locking arm 90 is provided with an engagement member 91 which engages with an engagement surface 92 on second clamping arm 13, a locking arm pivot 93 and pivot arm 94 with arresting pin 95. When the second clamping arm 13 is in the closed position, the locking arm 90 may be pivoted about pivot point 93 in order that engagement member 91 engages with engagement surface 92 in order to prevent pivotal movement of second clamping arm 13. When engagement member 91 is moved away from engagement surface 92 by movement of pivot member 94, arresting pin 95 limits the range of motion of the pivot member 94.
Assembly Assembly is achieved in accordance with the following:
1) Insert holder 15 into a hole 28 in first clamping arm 12;
2 ~ Insert locking button 21 into the bore 29 of first - 8 - 212~6~
clamping arm 12;
3) Insert spring 20 into first clamping arm 12 ensuring that it seats over locking button 21;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, Figure 1 illustrates a clamping and holding device 10 comprising a first clamping arm 12 with a general C shape. A second clamping arm 13 is pivotally mounted at one end of the first clamping arm 12.
Clamping arms 12 and 13 cooperate to engage an article upon which the clamping and holding device is to be mounted, such as for example, a section of an arm of a lawn chair illustrated at 14.
A holder 15 which may be in form of a tube with an interior diameter of about one inch is mounted on the first clamping arm 12 to extend laterally from the first clamping arm 12. As shown in Figure 2, holder 15 is mounted for pivotal movement about a horizontal axis transverse to the clamping arms 12 and 13. As shown in Figure 2, holder 15 has a mounting portion 16 which is conical with the smaller diameter close to holder 15. A retaining lip 17 is at the far end of mounting 16 to prevent it from being fully retracted from the first clamping arm 12. A serrated collar 18 is also provided having teeth 19 to permit the holder to be locked firmly in position at a variety of different angles. Upon assembly of holder 15 with main body 10 as shown in Figures 3, 4 and 5, a compression spring 20 urges locking button 21 against conically shaped mounting 16 to urge teeth 19 into engagement with teeth 22 in first 7 212~ 1.6 clamping arm 12. This structure provides a firm engagement between the holder 15 and the first clamping arm 12 at a variety of positions. However, the angular position of holder 15 can readily be adjusted by pulling holder 15 out in a downward direction with respect to Figure 5 to disengage teeth 19 and 22 and permit pivotal rotation.
A locking button 23 is also controlled by spring 20 and it provides a cam follower for engagement with a cam 24 shown in Figure 5. Cam 24 is secured in position within clamping arm 13 by pin 25 which engages locking button 26.
The interaction of cam 24 and cam follower 23 causes clamping arm 13 to be biased into a closed position to hold the article of furniture such as 14 between the clamping arms 12 and 13.
A locking arm 90 may also be pivotally mounted on the first clamping arm 12 to prevent inadvertent opening of the second clamping arm 13 from the closed position as shown in Figure 12. The locking arm 90 is provided with an engagement member 91 which engages with an engagement surface 92 on second clamping arm 13, a locking arm pivot 93 and pivot arm 94 with arresting pin 95. When the second clamping arm 13 is in the closed position, the locking arm 90 may be pivoted about pivot point 93 in order that engagement member 91 engages with engagement surface 92 in order to prevent pivotal movement of second clamping arm 13. When engagement member 91 is moved away from engagement surface 92 by movement of pivot member 94, arresting pin 95 limits the range of motion of the pivot member 94.
Assembly Assembly is achieved in accordance with the following:
1) Insert holder 15 into a hole 28 in first clamping arm 12;
2 ~ Insert locking button 21 into the bore 29 of first - 8 - 212~6~
clamping arm 12;
3) Insert spring 20 into first clamping arm 12 ensuring that it seats over locking button 21;
4) Insert locking button 23 into bore 29 ensuring that the button 23 seats into spring 20;
5) Position clamping arm 13 over projecting legs 30 and 31 in first clamping arm 12 and slide pin 25 through the arms 32 and 33 of clamp 13 and one leg 31 of first clamping arm 12 and cam 24 ensuring that the cam face is in alignment with locking button 23;
6) Position locking cap 26 through arm 32 of clamp arm 13 and bottom leg 30 of body 11, pressing pin 25 and locking cap 26 together until the pin 25 locks into the locking cap 26.
Figures 6 and 7 illustrate an alternative embodiment of this invention in which there are two sections, a clamping section 40 and a holding section 41. The clamping section 40 comprises a body 42 to which is pivotally secured jaws 43 20 and 44 which preferably are faced with rubber or similar material as shown at 45. Pivot pins 46 and 47 permit the jaws to pivot. A wing nut 48 threadably engages jaws 43 and 44 to clamp the device to an article of furniture. The first section also comprises serrated teeth 49.
The second section includes holder 41 which is mounted on body 50 having teeth 51 to engage teeth 49. A wing nut 52 is mounted on threaded shaft 53 so as to clamp teeth 49 and 51 into engagement or to permit pivotal movement of 30 section 2 with respect to section 1 about a horizontal axis for a variety of positions of holder 41. In the embodiment illustrated in Figures 6 and 7 the umbrella or other article supported by the holder cannot pass through holder 41 because of the location of wing nut 52. This embodiment 35 will therefore be particularly suitable for supporting a tray as illustrated in Figures 8 (a) or 8 (c) but can be used with a small umbrella as shown in Figure 8 (b). It will ` 2125616 g however be appreciated that if desired holder 41 can be located laterally of the wing nut to permit the shaft of the umbrella to pass unimpeded down through the holder.
Figure 8 illustrates applications of this invention.
In Figure 8(a) what is known as a "resin" chair 60 has a tray 64 attached to it by a clamp in accordance with this invention. Figure 8(b) shows a chair 60 to which umbrella shaft 62 has been secured by a clamp 63 in accordance with the invention. Figure 8(c) shows that tray 64 can be secured to chair 60 in a frontal position by clamp 65.
Figure 8(d) is a detail view of the top side of tray 64 showing a glass holder recess 65. Figure 8(e) shows the underside of tray 64 including glass holder 65 and a stub 66 to be attached to the holder of a clamp in accordance with the invention. Figure 8(f) shows a pair of clamps 67 and 68 to be attached to the side of a chair to support rods 69, which in turn support awning 70.
It will be noted from Figure 8 that a clamping and holding device in accordance with this invention can readily be attached in a variety of locations on the arms or elsewhere of outside furniture of the type illustrated.
Figures 9, 10, 11, 13 and 14 show an alternate embodiment of the invention where the second clamping arm 13 is provided with a bolt 80 which extends through channel 82 and the first clamping arm 12. Pivotal movement of second clamping arm 13 to open the clamp causes the bolt 80 to move through channel 82, thereby enabling an opening of typically 45. A wing nut may be threadably engaged upon the bolt 80 in order to secure the first clamping arm 12 with respect to the second clamping arm 13.
Figures 13 and 14 show an alternative embodiment of the invention wherein the clamping arm 12 is provided with an adjustable member 100 telescopically received on the clamping arm 12 adjacent the clamping region. The adjustable member 100 is adapted for longitudinal movement with respect to the clamping arm 12 to alter the relative length of the clamping arm 12 to permit the clamping and holding device 10 to be secured to articles of different sizes. The adjustable member 100 and clamping arm 12 are provided with locking means and guide means for securing the adjustable member 100 at a particular position and for providing correct alignment of the adjustable member 100 with respect to the clamping arm 12. The locking means may be a bolt 102 extending through the clamping arm 12 and adjustable member 100. The adjustable member 100 is provided with a longitudinal slot 104 to permit movement of the adjustable member 100 with respect to the clamping arm 12 with the bolt 102 extending through the clamping arm 12 and adjustable member 100. A nut 103 engaged upon the bolt 102 locks the clamping arm 12 with respect to the adjustable member 100. The clamping arm 12 is also provided with a guide peg 106 received in guide peg slot 108 on the adjustable member 100 to ensure alignment of the adjustable member 100 with respect to the clamping arm 12 and to ensure alignment of the clamping surfaces 110 and 112 with respect to one other.
The clamping surfaces 110 and 112 may also be provided with a variety of surface profiles for clamping the device 10 on articles with different surface profiles. For example, the clamping and holding device 10 may be provided with flat surfaces shown as clamping surfaces 110 and 112 or as concave surfaces 114 and 116 (dotted lines) for clamping the clamping and holding device 10 to tubular surfaces.
Figures 13, 14 and 14a also show an alternative embodiment for securing the holder 15 within the clamping arm 12. A clip 120 with retaining arms 122 is inserted into holes 124 in the clamping arm 12 in order that retaining arms 122 project into holder bore 28 in clamping arm 12 as shown in Figure 14. The retaining arms 122 are thereby - 11 2l2~6~
positioned between retaining lip 17 and collar 18 to prohibit removal of the holder from bore 28 while allowing displacement of the holder 15 to disengage teeth 19 from teeth 22 to allow pivotal movement of the holder 15 with 5 respect to the clamping arm 12.
Figures 15, 16, and 17 show an alternate embodiment of the invention, in particular for clamping on tubular surfaces. The clamp 150 is provided with two mating halves 152 and 154 having a hinge portion 156, a clamping portion 158 and a holder portion 160. The two halves 152 and 154 are joined together by hinge portion 156 where one half 152 is provided with a lip 162 which engages with undercut channel 164.
The clamping portion 158 is provided with opposed concave surfaces 166 and 168 which form a tube when the halves 152 and 154 are hinged together for clamping a tubular surface of similar shape and dimensions. A bolt 183 received in holes 180 with nut 182 secures the two halves together to firmly engage the clamp 150 around a tubular article (not shown).
The holder portion 160 receives a holder 15 between the two halves 152 and 154 when the two halves 152 and 154 are hinged together. A securing means in the form of a nut 170 and a bolt 172 retains the holder 15 within the assembled halves 152 and 154. The bolt 172 is received thorough longitudinal slots 174 and bore 176 in the holder 15. The longitudinal slots 174 permit pivotal movement of the holder 15 with respect to the halves 152 and 154.
The clamping portion may also be provided with a downsizer 190 in order that the clamp may be attached to tubular surfaces of different diameters. The downsizer 190 has a generally tubular body in two halves with a internal surface 192 and external surface 194. The internal surface 21~6~.5 192 is proportioned to engage the outer surface of a tube to which the clamp 150 is to be attached and the outer surface 194 is proportioned to engage the inner surface 166 of the clamping portion 158. The upper edge of the downsizer 190 is provided with an outwardly projecting lip 196 to seat the downsizer 190 against the corresponding upper edge of the clamping portion 158.
