Fastening element of a T-shaped profile hose, connection arrangement with the fastening element, setting device as well as manufacturing and connection method
Described are the fastening element of a T-shaped profile hose (e.g., made of a polymer material) in a connection arrangement, as well as the associated connection arrangement. Furthermore, a manufacturing method of the fastening element, a connection method of the connection arrangement with a setting device and the setting device with the connection arrangement are disclosed. The fastening element may be made of one-part sheet metal construction and may comprise a rectangular bottom with a central longitudinal axis having a first surface and a second surface opposite to the first surface. Furthermore, a plurality of locking teeth which project beyond the first surface on one side are adapted for penetrating into the polymer material of the T-shaped profile hose in use, and for avoiding a relative movement between fastening element and T-shaped profile hose in a direction parallel to the first surface.
1 . A connection arrangement for connecting a T-shaped profile hose made out of a polymer material with a setting device or a further T-shaped profile hose, with the connection arrangement comprising:
a) a basic element with a central longitudinal axis having a connecting means for fastening the basic element to the setting device or a further connection arrangement of a further T-shaped profile hose, wherein the basic element comprises a T-shaped recess for receiving the T-shaped profile hose, which extends in a longitudinal direction through the basic element and is open at a head end,
b) a locking element with which the T-shaped recess is closable perpendicular to the longitudinal axis, and
c) a fastening element consisting of a one-part sheet metal construction, and the fastening element comprising: a rectangular bottom with a central longitudinal axis having a first surface and a second surface opposite to the first surface, and a plurality of locking teeth which project beyond the first surface on one side and are adapted for penetrating into the polymer material of the T-shaped profile hose in use, and for avoiding a relative movement between fastening element and the T-shaped profile hose in a direction parallel to the first surface, wherein the fastening element is arranged in the T-shaped recess.
2 . The connection arrangement according to claim 1 wherein the central longitudinal axis of the fastening element and the central longitudinal axis of the basic element are aligned parallel to one another.
3 . The connection arrangement according to claim 1 , wherein the fastening element is connected to a bottom and/or one or more sidewalls of the T-shaped recess in the basic element such that the fastening element is secured against a movement relative to the basic element along the central longitudinal axis.
4 . The connection arrangement according to claim 1 , wherein the T-shaped recess comprises indentations in the basic element at one or more sidewalls, so as to secure the fastening element in the T-shaped recess against a relative movement to the basic element along the central longitudinal axis.
5 . The connection arrangement according to claim 1 , wherein in the T-shaped recess, a T-shaped profile hose is furthermore arranged and a central longitudinal axis of the T-shaped profile hose and the central longitudinal axis of the basic element are arranged parallel to one another in the connection arrangement.
6 . The connection arrangement according to claim 1 , wherein the basic element and/or the locking element is/are made of aluminum or steel.
7 . A setting device which is connected with a T-shaped profile hose made out of a polymer 20 material by means of the connection arrangement according to claim 1 .
8 . A connection method for connecting a T-shaped profile hose with a setting device or a further T-shaped profile hose by using the connection arrangement according to claim 1 , the method comprising:
a) providing the T-shaped profile hose and the connection arrangement according to claim 1 ,
b) arranging the fastening element in the T-shaped recess in the basic element of the connection arrangement,
c) arranging the T-shaped profile hose in the connection arrangement such that an end of the T-shaped profile hose is aligned flush with a face side of the basic element,
d) fixing the T-shaped profile hose in the T-shaped recess by arranging the locking element of the connection arrangement to the basic element, causing the plurality of locking teeth to penetrate the T-shaped profile hose, and
e) connecting the fixed T-shaped profile hose with the setting device or a further T-shaped profile hose.
9 . The connection arrangement according to claim 1 , wherein the plurality of locking teeth comprises at least a first locking tooth and at least a second locking tooth.
10 . The connection arrangement according to claim 9 , wherein the plurality of locking teeth comprises a plurality of first locking teeth and a plurality of second locking teeth.
11 . The connection arrangement according to claim 1 , wherein two sidewalls extend from the rectangular bottom which are arranged parallel and mirror-symmetrically to the central longitudinal axis and where the plurality of locking teeth are arranged at an end of the two sidewalls which faces away from the rectangular bottom.
12 . The connection arrangement according to claim 11 , wherein the sidewalls limit the rectangular bottom laterally and wherein there is a plurality of apertures in a transition portion between the rectangular bottom and the respective sidewall.
13 . The connection arrangement according to claim 11 , wherein at least one U-shaped recess is present in each of the two sidewalls, so that a lug is provided which projects in a direction away from the central longitudinal axis and is connected to the sidewall on one side.
14 . The connection arrangement according to claim 1 , wherein the rectangular bottom:
a) has at least one passage hole, and/or
b) has at least one lug projecting beyond the second surface on one side.
