Fig. 9 ~sheet 2) i~ a view, partly in section, showing the clamp of Fig. 2 clamped on a large round tube;
and Fig. 10 (~heet 1) is a per~pective view showing another embodiment of a clamp according to the invention.
Reference is first made to Fig. 1 which ~hows a typical prior art ~ign holder of the kind now in very com-mon use. The ~ign holder, generally indicated at 10, in-clude~ a U-shaped clamp 12 having a socket 14 on its up-per surface. The rod 16 of a sign 18 fits into the -~ ~ 4 - ~152478 socket 14. In use the U-shaped clamp 12 is simply spring fitted over a strut of appropriate size. It will be evident that a different size U-shaped clamp must be used for each size strut, and in addition the U-shaped clamp is not suitable for round struts.
Fig. 2 is a perspective view of a preferred embodiment of a clamp 20 of the invention. As shown in E~ig. 2, the clamp 20 includes a generally L-shaped member 22 having a first or upper leg 24 and a second or side leg 26. The leg 24 extends outwardly from leg 26 with an angle of about 80 to 90 degrees between them. Spaced along the first leg 24 are a number of holes 28. A
threaded socket 30 is welded or soldered to the top of the first leg 24 at the end where the first leg 24 meets the second leg 26.
The second leg 26 includes a threaded bolt 32 welded thereto near its free end. The bolt 32 extends in the same direction as the first leg 24 and is approximately parallel therewith.
The clamp 20 further includes a clamping member 34, shown in perspective in Fig. 2 and in edge view in Figs. 4 to 9 inclusive. The clamping member 34 includes a first end section 36, which normally is generally linear and which has a curved tongue 38 projecting from its free end. The tongue 38 is adapted to fit into any of the holes 28.
The clamping member 34 also includes a second end section 40, which is offset from the first end section 36 towards the second leg 26 when the first end section ~ 5 ~ 2478 36 is connected to the first leg 24. The second end sec-tion 40 is also preferrably generally linear.
The first and second end sections 36, 40 are connected by a generally S-shaped curved section 42.
The curved section 42 as viewed from the right hand side in Figs. 4 through 9 includes a convexly curved portion 44 and a concavely curved portion 46.
The second end section 40 also includes a slot 48 therein near its free end to accommodate the bolt 32.
In use, the L-shaped member 22 is first fitted over the strut or tube on which the clamp is to be located.
The tongue 38 is then inserted through an appropriate hole 28, the clamping member 34 is pressed toward the second leg 26 of the L-shaped member 22, with the bolt 32 pro-truding through the slot 48, and a nut 50 is then tight-ened on the bolt 32 to hold the clamp 20 in position.
It will be seen from Figs. 4 to 9 that the shape provided insures that the tubing on which the clamp i~ located is held at least at three point~ in all cases.
For example in the Fig. 4 situation, the large square tube 52 i~ clamped along its entire side 54 and also at its corners 56 and 58. The same situation prevails in Fig. 5, although it will be ~een that the ~mall square tube 60 is held at a different location, i.e. further down the clamping member 34.
The rectangular tube 62 shown in Fig. 6 is held in a manner similar to the square tube 52 of Fig. 4, but it will be appreciated that as the length to width ratio of the rectangular tube changes, the location of - 6 - 1 lS 2 47 8 the clamping points on the clamping member 34 may vary.
In addition the orientation of the clamp 20 on the rectang-ular tube 62 can be rotated through 90 degrees, as shown in Fig. 7, in which case the rectangular tube 62 is held in S the sarne manner as the square tube 60 of Fig. 5.
As shown in Figs. 8 and 9, when round tube 64a, 64b is used, the tube is held at point 66 on the second leg 26 of the L-shaped member 22, and at points 68 and 70 of the clamping member 34. The points 68, 70 will shift toward each other in the case of the smaller diameter tube 64a shown in Fig. 8, and will shift away from each other in the case of the larger diameter tube 64b shown in Fig. 9.
Although a threaded socket 30 has been shown for attachment to a sign holder, various other attachment methods may be used for connecting signs and the like to the clamp of the invention.
If desired, and as shown in Fig 10, where primed reference numerals indicate parts corresponding to those of Figs. 1 to 9, the clamp can be "reversed" by integrally con-necting the leg 24' to the first end section 36' and placing the tongue 38' on the end of the leg 26'. The socket 30' is placed remote from the frce end of leg 24'. The Fig. 10 clamp will function essentially in the same way as the pre-viously described embodiment.
(i) a first end section, (ii) a second end section offset from said first end section towards said first leg when said second clamping member is connected to said first clamping member, (iii) a generally S-shaped curved section inte-grally joining said first and second end sections, ~c) a second leg connected to one of said first leg and said first end section and extending toward the other of ~aid first leg and said first end section when said first and second clamping members are connected together, (d) means for releasably connecting said second leg and said other of said first leg and first end section, and (e) mean~ for releasably connecting said first leg and said Pecond end section.

Reference is first made to Fig. 1 which ~hows a typical prior art ~ign holder of the kind now in very com-mon use. The ~ign holder, generally indicated at 10, in-clude~ a U-shaped clamp 12 having a socket 14 on its up-per surface. The rod 16 of a sign 18 fits into the -~ ~ 4 - ~152478 socket 14. In use the U-shaped clamp 12 is simply spring fitted over a strut of appropriate size. It will be evident that a different size U-shaped clamp must be used for each size strut, and in addition the U-shaped clamp is not suitable for round struts.
Fig. 2 is a perspective view of a preferred embodiment of a clamp 20 of the invention. As shown in E~ig. 2, the clamp 20 includes a generally L-shaped member 22 having a first or upper leg 24 and a second or side leg 26. The leg 24 extends outwardly from leg 26 with an angle of about 80 to 90 degrees between them. Spaced along the first leg 24 are a number of holes 28. A
threaded socket 30 is welded or soldered to the top of the first leg 24 at the end where the first leg 24 meets the second leg 26.
The second leg 26 includes a threaded bolt 32 welded thereto near its free end. The bolt 32 extends in the same direction as the first leg 24 and is approximately parallel therewith.
The clamp 20 further includes a clamping member 34, shown in perspective in Fig. 2 and in edge view in Figs. 4 to 9 inclusive. The clamping member 34 includes a first end section 36, which normally is generally linear and which has a curved tongue 38 projecting from its free end. The tongue 38 is adapted to fit into any of the holes 28.
The clamping member 34 also includes a second end section 40, which is offset from the first end section 36 towards the second leg 26 when the first end section ~ 5 ~ 2478 36 is connected to the first leg 24. The second end sec-tion 40 is also preferrably generally linear.
The first and second end sections 36, 40 are connected by a generally S-shaped curved section 42.
The curved section 42 as viewed from the right hand side in Figs. 4 through 9 includes a convexly curved portion 44 and a concavely curved portion 46.
The second end section 40 also includes a slot 48 therein near its free end to accommodate the bolt 32.
In use, the L-shaped member 22 is first fitted over the strut or tube on which the clamp is to be located.
The tongue 38 is then inserted through an appropriate hole 28, the clamping member 34 is pressed toward the second leg 26 of the L-shaped member 22, with the bolt 32 pro-truding through the slot 48, and a nut 50 is then tight-ened on the bolt 32 to hold the clamp 20 in position.
It will be seen from Figs. 4 to 9 that the shape provided insures that the tubing on which the clamp i~ located is held at least at three point~ in all cases.
For example in the Fig. 4 situation, the large square tube 52 i~ clamped along its entire side 54 and also at its corners 56 and 58. The same situation prevails in Fig. 5, although it will be ~een that the ~mall square tube 60 is held at a different location, i.e. further down the clamping member 34.
The rectangular tube 62 shown in Fig. 6 is held in a manner similar to the square tube 52 of Fig. 4, but it will be appreciated that as the length to width ratio of the rectangular tube changes, the location of - 6 - 1 lS 2 47 8 the clamping points on the clamping member 34 may vary.
In addition the orientation of the clamp 20 on the rectang-ular tube 62 can be rotated through 90 degrees, as shown in Fig. 7, in which case the rectangular tube 62 is held in S the sarne manner as the square tube 60 of Fig. 5.
As shown in Figs. 8 and 9, when round tube 64a, 64b is used, the tube is held at point 66 on the second leg 26 of the L-shaped member 22, and at points 68 and 70 of the clamping member 34. The points 68, 70 will shift toward each other in the case of the smaller diameter tube 64a shown in Fig. 8, and will shift away from each other in the case of the larger diameter tube 64b shown in Fig. 9.
Although a threaded socket 30 has been shown for attachment to a sign holder, various other attachment methods may be used for connecting signs and the like to the clamp of the invention.
If desired, and as shown in Fig 10, where primed reference numerals indicate parts corresponding to those of Figs. 1 to 9, the clamp can be "reversed" by integrally con-necting the leg 24' to the first end section 36' and placing the tongue 38' on the end of the leg 26'. The socket 30' is placed remote from the frce end of leg 24'. The Fig. 10 clamp will function essentially in the same way as the pre-viously described embodiment.
