Mounting unit with adjustable lockable pivot arm

Claim 2

A mounting unit for mounting a game warning siren to a mounting surface comprising: a base plate attachable to said mounting surface; a pivot arm for attachment to said siren; and a bipartite slide block having a pivot arm retaining means for retaining said pivot arm and a locking means for preventing rotation of said pivot arm, said pivot arm being pivotably mounted to said pivot arm retaining means; wherein said locking means is elastically swingable with respect to said pivot arm retaining means and wherein slidable insertion of said slide block into said base plate fixes the position of said pivot arm retaining means with respect to said locking means and prevents rotation of said pivot arm.

Claim 3

The mounting unit of claim 1 wherein said pivot arm is mountd to said pivot arm retaining means in a region adjacent to said locking means and insertion of said slide block into said base plate produces tension in said slide block.

Claim 4

The mounting unit of claim 1 wherein said locking means is provided with a first geared portion and said pivot arm is provided with a second geared portion for mating engagement with said first geared portion of said locking means.

Claim 5

The mounting unit of claim 3 wherein said pivot arm retaining means inserted into said base plate urges said pivot arm against said locking means and matingly engages said second geared portion of said pivot arm with said first geared portion of said locking means.

Claim 6

The mounting unit of claim 1 wherein said pivot arm retaining means of said slide block inserted into said base plate clamps a shaft of said pivot arm thereby preventing rotation of said pivot arm.

Claim 7

The mounting unit of claim 5 wherein force applied by said locking means to said pivot arm retaining means as a result of insertion of said locking means into said base plate clamps said shaft.

Claim 8

The mounting unit of claim 1 wherein said base plate is provided with an end stop to limit insertion of said slide block.

Claim 9

A mounting unit for mounting a game warning siren to a mounting surface comprising: a pivotably mounted support arm attachable to said siren; a bipartite slide block adapted to pivotably receive said pivotably mounted support arm; means for fixing said pivotably mounted support arm with respect to said slide block in a preassigned position and comprising a first geared portion on said support arm and a second mating geared portion on said slide block wherein said support arm and said slide block are elastically displaceable in a direction to engage and disengage said first geared portion from said second geared portion; and means for affixing said slide block to said mounting surface.

Claim 10

A mounting unit for mounting a game warning siren to a mounting surface comprising: a pivotably mounted support arm attachable to said siren; a bipartite slide block adapted to pivotably receive said pivotably mounted support arm; means for fixing said pivotably mounted support arm with respect to said slide block in a preassigned position and comprising a first geared portion on said support arm and a second mating geared portion on said slide block wherein said support arm and said slide block are elastically displaceable in a direction to engage and disengage said first geared portion from said second geared portion; and means for affixing said slide block to said mounting surface.

Claim 11

The mounting unit of claim 8 wherein said means for fixing said support arm comprises clamping means for clamping a shaft of said support arm.

Claim 12

The mounting unit of claim 8 wherein said means for affixing said slide block comprises an adhesive.

Claim 13

The mounting unit of claim 8 wherein said means for affixing said slide block comprises a base plate into which said slide block is insertable.

Claim 14

The mounting unit of claim 11 wherein said base plate is mounted to said mounting surface.

Claim 15

A high frequency game warning siren mountable on a motor vehicle for use in warning animals of oncoming vehicles comprising: a siren portion geometrically and acoustically configured so as to produce a high frequency sound upon the passage of air therethrough; a pivot arm attached at a first end to said siren; a bipartite slide block having a pivot arm retaining means for retaining said pivot arm and a locking means for preventing rotation of said pivot arm; wherein said bipartite slide block is provided with an opening at least partially therethrough, said opening adapted to receive a shaft of said pivot arm wherein said locking means comprises a geared portion attached to said pivot arm and a geared portion attached to said slide block, said geared portions matingly engaging each other when said slide block is inserted into said base plate, thereby preventing rotation of said pivot arm and said siren; and a base plate attachable to said motor vehicle, said slide block being insertable into said base plate.

Claim 16

A high frequency game warning siren mountable on a motor vehicle for use in warning animals of oncoming vehicles comprising: a siren portion geometrically and acoustically configured so as to produce a high frequency sound upon the passage of air therethrough; a pivot arm attached at a first end to said siren; a bipartite slide block having a pivot arm retaining means for retaining said pivot arm and a locking means for preventing rotation of said pivot arm; wherein said bipartite slide block is provided with an opening at least partially therethrough, said opening adapted to receive a shaft of said pivot arm wherein said locking means comprises a geared portion attached to said pivot arm and a geared portion attached to said slide block, said geared portions matingly engaging each other when said slide block is inserted into said base plate, thereby preventing rotation of said pivot arm and said siren; and a base plate attachable to said motor vehicle, said slide block being insertable into said base plate.

Claim 17

The high frequency game warning siren of claim 13 wherein said opening has a diameter adjustable in accordance with force applied to said locking means.

Claim 18

The high frequency game warning siren of claim 13 wherein said locking means comprises a movable member which causes a diameter of said opening to decrease and a surface defining said opening to contact said shaft of said pivot arm with sufficient force to prevent rotation thereof.
