Abstract

Abstract A pivot mechanism for a housing laterally arranged at a support, such as a stand or the like, especially a housing for a medical instrument, comprising a first axle body and a second axle body, the second axle body being rotatably mounted at one side or end in the first axle body and at the other side or end is capable of being operatively connected with the housing. The first axle body and the second axle body are mounted in a headpiece such that the housing is horizontally rotatable about an essentially vertical lengthwise axis of the first axle body and vertically pivotable about an essentially horizontal lengthwise axis of the second axle body. The headpiece has at least one friction surface for the horizontal rotational movement and further friction surfaces for the vertical pivotal movement. For braking such movements there is provided but a single resilient element such as a compression or pressure spring.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 158 words
A pivot mechanism for pivotably laterally securing a housing at a stand, comprising: a first axle body; a second axle body; said second axle body being rotatably mounted at one end in the first axle body; said second axle body being capable of being operatively connected at its other end with the housing; a headpiece; means for mounting the first axle body and the second axle body in said headpiece such that the housing can be horizontally rotated about an essentially vertical lengthwise axis of the first axle body and vertically pivotable about an essentially horizontal lengthwise axis of the second axle body; means providing at least one friction surface for the headpiece for horizontal rotational movement of the housing about said vertical lengthwise axis; means providing further friction surfaces for the headpiece for vertical pivotal movement of the housing about said horizontal lengthwise axis; and only a single resilient element for braking said movements of the housing.
Claim 2
Dependent Claim 158 words
A pivot mechanism for pivotably laterally securing a housing at a stand, comprising: a first axle body; a second axle body; said second axle body being rotatably mounted at one end in the first axle body; said second axle body being capable of being operatively connected at its other end with the housing; a headpiece; means for mounting the first axle body and the second axle body in said headpiece such that the housing can be horizontally rotated about an essentially vertical lengthwise axis of the first axle body and vertically pivotable about an essentially horizontal lengthwise axis of the second axle body; means providing at least one friction surface for the headpiece for horizontal rotational movement of the housing about said vertical lengthwise axis; means providing further friction surfaces for the headpiece for vertical pivotal movement of the housing about said horizontal lengthwise axis; and only a single resilient element for braking said movements of the housing.
Claim 3
Dependent Claim 16 words
The pivot mechanism as defined in claim 1, wherein: said resilient element comprises a pressure spring.
Claim 4
Dependent Claim 66 words
The pivot mechanism as defined in claim 2, wherein: for braking the horizontal rotational movement of the housing said at least one friction surface defines a substantially ring-shaped friction surface formed at the headpiece; said stand having an upright tube; a pressure ring rigidly connected for rotation with said upright tube of said stand; said pressure ring bearing against said ring-shaped friction surface of the headipiece.
Claim 5
Dependent Claim 52 words
The pivot mechanism as defined in claim 1, wherein: for braking the vertical pivotal movement of the housing said further friction surfaces are operatively associated with the second axle body and cooperate with a sliding element provided at the first axle body; and a friction surface provided at the second axle body.
Claim 6
Dependent Claim 21 words
The pivot mechanism as defined in claim 4, wherein: said friction surface provided at the second axle body comprises a recess.
Claim 7
Dependent Claim 84 words
The pivot mechanism as defined in claim 4, wherein: said headpiece is provided with a first bore for receiving the first axle body; said headpiece is provided with a second bore arranged essentially transversely with respect to said first bore; said second bore receiving the second axle body; said second bore having two edges constituting said further friction surfaces; said second bore having a substantially groove-like recess at a side of the headpiece directed towards an underside thereof and extending essentially in radial direction.
Claim 8
Dependent Claim 36 words
The pivot mechanism as defined in claim 6, wherein: said second axle body is positioned in radial direction and secured against axial displacement by means of the sliding element operatively associated with the first axle body.
Claim 9
Dependent Claim 73 words
The pivot mechanism as defined in claim 1, further including: a stand having an upright tube provided for the housing; a pressure ring cooperating with the first axle body; said first axle body having a lower end; a centering ring mounted at the lower end of the first axle body; said pivot mechanism being centrally guided by means of the pressure ring and the centering ring in the upright tube of the stand.
Claim 10
Dependent Claim 147 words
A pivot mechanism for pivotably laterally securing a housing at a stand, comprising: a first body; a second body; said second body being rotatably mounted at one end in the first body; said second body being capable of being operatively connected at its other end with the housing; a headpiece; means for mounting the first body and the second axle body in said headpiece such that the housing can be horizontally rotated about an essentially vertical axis of the first body and vertically pivotable about an essentially horizontal axis of the second body; means providing at least one friction surface for the headpiece for horizontal rotational movement of the housing about said vertical lengthwise axis; means providing further friction surfaces for the headpiece for vertical pivotal movement of the housing about said horizontal lengthwise axis; and a single resilient means for braking said movements of the housing.
Claim 11
Dependent Claim 147 words
A pivot mechanism for pivotably laterally securing a housing at a stand, comprising: a first body; a second body; said second body being rotatably mounted at one end in the first body; said second body being capable of being operatively connected at its other end with the housing; a headpiece; means for mounting the first body and the second axle body in said headpiece such that the housing can be horizontally rotated about an essentially vertical axis of the first body and vertically pivotable about an essentially horizontal axis of the second body; means providing at least one friction surface for the headpiece for horizontal rotational movement of the housing about said vertical lengthwise axis; means providing further friction surfaces for the headpiece for vertical pivotal movement of the housing about said horizontal lengthwise axis; and a single resilient means for braking said movements of the housing.
