## Abstract

A hook-type connection for the play-free connection of two parts. A first part comprises a hook with wings which engage an edge which is formed on an abutment on a second part. In the assembled condition, the wings are pivoted about the longitudinal axis of the shank of the hook, so that the hook is subjected to a torsional load. A hook-type connection of this kind offers optimum freedom of design for the different manufacturing tolerances of the parts and the hook-type connection occuring during practice.

## Claims

### Claim 1

A hook-type connection for the play-free connection of a first part to a second part, the hook-type connection comprising:
a flexible hook with a shank and at least one wing mounted on said shank, said shank connected to said first part having a pressure edge, and
an abutment which is connected to said second part having an abutment edge with which said pressure edge cooperates, at least one of the two edges enclosing an acute angle with a plane which extends substantially perpendicularly of the longitudinal direction of said shank of said hook, said hook being locally structurally weakened in the longitudinal direction of said shank when a torque is exerted on said shank by at least said one wing which forms part of said hook and which is connected to said shank adjacent the end which is remote from said first part, said wing having an edge which faces said first part and comprises said pressure edge.

### Claim 2 (depends on 1)

A hook-type connection as claimed in claim 1 wherein said pressure edge encloses an acute angle with a first plane which extends perpendicularly of the longitudinal direction of said shank and also encloses an acute angle with a second plane which extends parallel to the longitudinal direction of said shank and perpendicularly of the bending plane of said shank.

### Claim 3 (depends on 1, 2)

A hook-type connection as claimed in claim 1 or 2 wherein said hook comprises two identical wings which are connected to said shank adjacent the end thereof which is remote from the first part, said wings being symmetrically situated with respect to the longitudinal direction of said shank and lying mainly in two intersecting planes.

### Claim 4 (depends on 1)

A hook-type connection as claimed in claim 1 wherein said abutment edge of said abutment connected to said second part extends perpendicularly to the longitudinal direction of said shank.

### Claim 5 (depends on 4)

A hook-type connection as claimed in claim 4 wherein said abutment connected to said second part is formed by an elongated thickened portion of a wall of said second part which thickened portion extends perpendicularly to the longitudinal direction of said shank.

### Claim 6 (depends on 1)

A hook-type connection as claimed in claim 1 wherein said hook and said first part connected thereto are moulded as one unit from a synthetic material.

### Claim 7 (depends on 1)

A hook-type connection as claimed in claim 1 wherein said first part is formed by a mask of a television receiver, said second part being formed by a cabinet of said television receiver.

### Claim 8 (depends on 1)

A television receiver with a mask which is connected to a cabinet by means of several hook-type connections as claimed in claim 1, said hook-type connections being distributed along the circumference of said mask.
