`MOUNTING BRACKET
`
`FIELD OF THE INVENTION
`
`invention relates to a mounting bracket,
`The present
`whereby is meant a clamp device by means of which an
`object, for instance an elongated object, an antennaetc, can
`be secured to a ground pole, a tube or a post, a ground
`anchored post or a similar anchoring support. The clamp
`device comprisesa first clamp part adapted to be secured to
`the object to be mounted against the pole, and a second
`clamp part adapted to embracethe pole and to be tightened
`to the first clamp part, generally by means of a screw-nut
`connection means. The invention also relates to a mounting
`bracket, which alternatively can be used for panning the
`object if the second clamp part is mounted on a supporting
`structure such as a wall.

`
`The object of the invention has been to suggest a clamp
`device of the above mentioned type which is designed so
`
`2
`that it is very well possible for a single installation engineer
`to mount the antenna against an antenna pole. The clamp
`device comprisesa first clamp, the base clamp, adapted to be
`anchored against an antenna, a second clamp, the tightening
`clamp, adapted to be tightened against said first clamp by
`means of a screw-nut joint with the antenna pole there
`between. The clamps preferably are formed as U-shaped
`brackets (< >) which along the branches thereof are
`formed with U- or V-shaped pole guide groovesor recesses.
`According to the invention the second clamp, the tight-
`ening clamp,
`is formed with two elongated slots at the
`intermediate side of said clamp and extending in the longi-
`tudinal direction of the clamp, a first slot which may be
`closed and a second slot which is open at the end of the
`clamp for passage of the mounting bolts. The screws for
`tightening of the clamps against the pole are formed so that
`said screws can notrotate in the first clamp, the base clamp.
`This is provided in that said screwsare of carriage bolt type
`having square bolt parts adjacent the head thereof, which
`square bolt parts engage square bores of said base clamp.
`Alternatively said bolts can be welded or by other means
`secured to said base clamp.
`Whenusing the above mentioned clamp device the screws
`are pulled through the bores of the base clamp and through
`the closed slot of the tightening clamp, and nuts are loosely
`screwed onto the outer ends of the screws. Thereby the
`clamp devices forms an integral part in which the tightening
`clamp is hanging freely from the corresponding clamp
`screw, and the twin clamp device can simply be tightened by
`a single installation engineer using only one hand, whereby
`the antenna with the integral clamp device can be held by the
`second hand.

`The invention hasbasically been developed in connection

`
`DESCRIPTION OF PREFERRED
`EMBODIMENTS
`
`As mentioned abovea prior art clamp device comprises a
`first clamp 1, a base clamp, adapted to be connected to a
`base, for instance an antenna(notillustrated), for instance by
`meansof screws extending throughboresofsaidfirst clamp,
`and adapted to engage an “inner”portion of a pole, a second
`clamp 2 adapted to engage an “outer” portion of a pole, and
`two screws 3 adapted to extend through bores 4 and 5 of
`clamp 1 and clamp 2, respectively and having nuts 6 for
`tightening the second clamp 1 to the first clamp 2 thereby
`fixedly mounting the base (antenna) to a pole. Preferably the
`base clamp 1 can be formed with two lugs 7 or two holes 11
`by means of which an antenna can be mounted, for instance
`tiltable, in relation to the base clamp, of by means of which
`a coupling box, or a similar means can be connected to the
`clamp device.
`The clamp device according to the invention is basically
`of the same type as said prior art clamp device shown in FIG.

`into place against the pole with said pole located between the
`two bolts 10. The tightening clamp 2 is moved longitudi-
`nally so that the bolt 10 engages the inner, closed end of the
`elongated slot 12. In this position the tightening clamp 2 can
`be rotated clockwise past the left hand bolt 10 as shown in
`FIGS. 4 and 5, whereupon said second clamp 2 is moved
`back so that the bolt engages the closed outer end of the
`closed slot 12, whereby the second bolt 10 is in a position
`with the open slot 13 embraces same and the corresponding
`screw is positioned at or close to the bottom end of said slot
`13. Now the two nuts can easily be tightened by one hand
`of the installation engineer, who holds the antenna with the
`clamp device with his second hand. FIG. 5 shows the
`antenna with the clamp device finally securely attached
`against the pole 15 using a clamp device according to the
`invention.

`
`It is to be understood that the antenna necessarily has to
`be mounted by meansof two, or more, spaced clamp devices
`of the same type as described above, and which clamp
`devices are mounted on different levels against the base
`(antenna).
`In FIG. 6 a further embodimentof the invention is shown.
`A base clamp 1 and a tightening clamp 2 of the kind
`described above, are provided with holes in order to expand
`the possibilities of use of the mounting bracket. One pair of
`holes in the base clamp 1 and one pair of holes in the
`tightening clamp 2 are together with a screw 16 and nut 17
`forming a rotary joint or a hinge, which allows the base
`clamp 1 and the tightening clamp 2 to be rotated in relation

`to each other around an axis defined by the screw 16. An arm

`a screw 20, which also passes through two holes in the

`thereof for engaging a pole 15, and an interconnecting side
`having elongated slots 12 and 13. Said slots have a width
`which correspondsto, or is slightly wider than the diameter
`of the connection bolts 10 and a length whichisat least twice
`the diameter of said bolts 10. For mounting reasons the
`closed slot 12 has to be longer than the openslot, preferably
`at least one bolt diameter longer than the open slot 13.
`The clamp device preferably is pre-mounted, in factory or
`at the ground, to the object to be mounted, for instance an
`antenna,in that the bolts 10 are pulled through the two bores
`8 of the base clamp 1, and one of said bolts is also pulled
`through the closed, elongated slot 12 of the outer clamp 2,
`named the tightening clamp, and in that nuts 6 are loosely
`screwed onto the outer ends of the two bolts 10.
`
`In FIG. 7 the embodiment of FIG. 6 is shown in a top
`view. Here the tightening clamp 2 is secured to a wall 24, by
`means of screws (not shown) through holes in the interme-
`diate portion of the tightening clamp 2. The object to be
`secured, e.g. an antenna 29 is mount e d on the base clamp
`1 as described above, e.g. by screws through the lugs 7. By
`the arrangementof this hinge and locking member, i.e. arm
`18, an antenna can be panned, Le. its rotational position in
`respect of its vertical longitudinal axis can be adjusted to a
`desired value. The tightening clamp 2 is further provided
`with a scale where the position of the edge 26 of the base
`clamp indicates the angle between the base clamp 1 and the
`tightening clamp 2. As shown,the holes in the base clamp
`The way of mounting the antenna with the clamp device
`1 for the screws 16, 22 are symmetrical. Further additional
`on the pole is illustrated in FIGS. 4 and 5. The base clamp
`holes 27, 28 are provided in the tightening clamp 2 as well
`1 is screwed or otherwise connected to the base, e g the
`as an additional scale. This enables the hinge to be movedto
`holes 28 and the holes for the screw 22, and the arm 18 to
`antenna. The tightening clamp 2 is hanging freely in the
`screw 10 extending through the closed slot 12, that is in the
`be connected to holes 27 and the holes in the base clamp for
`right bolt as shown in FIGS. 4 and 5 but can not be released

`FIG. 9 illustrates an antenna 29 mounted on a pole 15 by
`means of prior art mounting brackets 1, 2. The mounting
`bracket according to the invention is used in a similar way,
`when used on a pole, or similar.
`It
`is evident
`that
`the
`mounting of an antenna, when using a mounting bracket
`according to the invention, which can be pre-assembled so
`that no loose parts have to be added during the mounting on
`the pole,
`is much simpler then when using a prior art
`mounting bracket with numerous loose parts to be added
`during the mounting on the pole.
