DEVICE FOR THE CLAMPING TOGETHER OF TWO BARS OR TUBES AT AN ANGLE WITH ONE ANOTHER Filed March 9, 1954 Q INVENTOR Tll 0770 [7109/5 7'/A/.V r/E/YSEN ATTORNEYS DEVICE FOR THE CLAMPING TOGETHER OF.
TWO BARS OR TUBES AT AN ANGLE WITH ONE ANOTHER Otto Christian Jensen, Gentofte, Denmark, assignor it); H. StIriuers Chemiske Laboratorium, Copenhagen,
enmar This invention relates to devices for the clamping together of two bars or tubes at an angle with one another. Such devices or clamps usually comprise two clampmg members adapted to be clamped together on two mutually crossing bars so as to press such bars directly against one another, each clamping member having a seat to receive one of the bars, the two seats being disposed at an angle with one another and being constgucted to support their respective bars from opposite si es.
In the known clamps of this type, the seats will ordinarily be relatively short so that it is diflicult e. g. to obtain great accuracy of the angle at which the two bars will be disposed. Moreover, in the known clamps, the point of contact between the two bars will be located between the said two seats, and consequently it will be diflicult on loosening the clamp to separate the two bars from one another in a lateral direction, such as is often desirable e. g. when the bars are very long or have protruding objects fastened thereto. Also, owing to the said arrangement of the known clamps, it is not possible in the use of the clamp to substitute e. g. a plane or cylindrical surface for one of the bars or in other words to use the clamp for attaching a bar to a plane or cylindrical surface.
It is an object of the invention to construct a clamp of simple and inexpensive design and which is easy to operate for the clamping together of crossing bars and for the subsequent separation of huch bars in a lateral direction when desired.
It is also an object of the invention to construct a clamp by means of which two bars may be clamped together at a right angle with satisfactory accuracy.
A further object of the invention is to construct a clamp suitable not only for the clamping together of two bars but optionally also for the clamping together of one bar and a flat or curved object.
With these objects in view, the invention consists of the arrangements and combinations set forth in the appended claims. A specific embodiment of the invention will in the following be described with reference to the accompanying drawing, in which Fig. 1 shows one example of a clamp according to the invention, in exploded view,
Fig. 2 the clamp in position for the clamping together of two bars at a right angle with one another, the view being taken from one side of the clamp,
Fig. 3 the same as viewed from one end of the clamp, and
Fig. 4 a view similar to Fig. 3, but with a cylindrical object substituted for one of the bars.
In Figs. 1, 3 is a clamping member which is made from sheet material in the form of an elongated strip provided with two lateral lugs 5 and 6 at one end and an end lug 4 at the other end. The lateral lugs 5 and 6 are bent at an angle of 90 relative to the body of the clamping member along longitudinal lines 15 and 16 United States Patent 0 and are provided with angular notches 17, which form a seat adapted to receive a bar or tube 1, so as to support said bar or tube from one side. I
The end lug 4 is similarly bent along a transverse bending line 18 and is provided with an angular notch 19 forming a seat adapted to receive a second bar or tube 2 in a position at right angles to the bar or tube 1 received in the seat formed by the notches 17 and to support the bar 2 from the same side as that from which the bar 1 is supported in the seat 17.
8 is a second clamping member which comprises a book 7 and a threaded shank 9 received in a hole 11 intermediate the seats of the first clamping member 3. The hook portion 7 of the second clamping member forms an angular seat which is substantially aligned with the seat 19 of the first clamping member but is inverted relative thereto so as to support the bar or tube 2 from the other side.
To facilitate the manipulation of the clamp, in the construction shown, the shank 9 is flattened as indicated at 10, and the hole 11 is similarly constructed with a flat side 12 so that the clamping member 8 cannot rotate relative to the clamping member 3. In this manner the seats formed by the hook 7 and the lug 4 of the clamping member 3 respectively will always remain substantially aligned, also when the clamp is being engaged with or disengaged from a pair of bars or tubes to be connected with one another.
In order to use the clamp, one bar 1 is placed in the seat formed by the angular notches of the lugs 5 and 6 and a second bar 2 is placed in the seats formed by the lug 4 and the hook 7. The two clamping members are thereupon clamped together by tightening a nut 13 engaged with the thread of the shank 9 whereby the two bars are pressed directly against one another and at the same time are pressed against their respective seats. When it is again desired to separate the two bars or tubes from one another, the nut 13 is loosened and as will be seen, it is possible already after a relatively small loosening movement to separate the two bars or tubes by pulling them out in the transverse direction, since none of the tubes interferes with such pulling out of the other tube.
As illustrated in Fig. 4 and in dotted lines in Fig. 2, the clamp can also be used for attaching one bar 2 to an object other than a bar or tube such as e. g. a fiat or curved object 14. In this case, the fiat or curved object takes the place of the bar 1 and is engaged by the lugs 5 and 6 though of course it cannot pass into the angular notches thereof. This use of the clamp is possible owing to the fact that the lugs 5 and 6 are provided at the end of one of the clamping members, so that there is no obstacle to the moving in and out of objects between the bar 2 and the lugs 5 and 6.
I claim:
1. A clamp comprising a clamping member provided at one end with two mutually parallel and spaced lugs having aligned notches forming a seat to receive and support a rod from one side, and provided at its other end with a lug perpendicular to said first-mentioned lugs and having a notch forming a second seat to receive a second rod in a position perpendicular to said first-mew tioned rod and to support said second-mentioned rod from the same side as that from which said first-mentioned rod is supported in said first-mentioned seat, a second clamping member having a counter seat located intermediate said seats of said first-mentioned clamping member and being substantially aligned with but inverted relative to said second-mentioned seat of said first-mentioned clamping member so as to be capable of supporting said second-mentioned rod from the other side, and
